As the stakeholders are ready embracing the power of intelligence for a futuristic lighting, Indian lighting system is seemingly on the verge of a complete facelift.
Intelligent lighting is the most versatile technology that can be used in most of the LED lighting applications in the form of the ‘Internet of Things’ (IoT) – a platform that is provisioned with multifarious capabilities like environmental monitoring and asset tracking, which can be scaled to innumerable real-time IoT applications. It can be energy management, remote asset monitoring, ready-to-deploy point solution derived from this best in the class platform. In short, it enables the users to control the entire outdoor or indoor lighting system in one console.
Whether it is local street lighting, highway to sports & arena, from building facades to basement parking, one can now control the lighting operations from anywhere in the world. The remote switching and monitoring system provides most effective intelligent controls, facilitating high energy savings and proven ROI, whether through retrofitting the existing luminaire fixtures or by integrating any futuristic lighting technologies.
Lighting currently is a US$ 2 billion-market in India and is growing at a consistent rate of over 14% per year. Like most developing countries, India also faces shortage of electrical energy which hampers the overall economic growth. While the Government has been focusing on generation enhancement, the supply-demand gap continues to surge and calls for immediate attention. Energy saving products and systems are a priority for the entire nation and this is where lighting can contribute to reduce energy consumption.
The Indian Lighting Industry
ELCOMA (Electric lamp and component manufacturers’ association of India), the Apex body of lighting manufacturers in India recently organised a Conference on Intelligent Lighting Designs in New Delhi to mark the beginning of a series of such events in various other cities to disseminate knowledge and enhance awareness of the industry stakeholders to enable them handling and catering to the high-tech requirements of the proposed smart cities. Experts holding forte on intelligent lighting shared their ideas of futuristic lighting.
Held in coordination with EESL, Government of India, the Conference was well supported by Philips, Osram, Crompton Greaves, Jaquar, Havells and Bajaj. The event brought together experts, who presented papers on new technology and applications in intelligent lighting for smart cities, wireless lighting control, smart street lighting, and the footprints of EESL’s national plan for street lighting. In all, the event was designed to cover all the topics of immediate and long term interest of the Indian lighting fraternity.
In his inaugural speech, Sunil Sikka, Past President Elcoma and President – Havells India Ltd., gave a brief about the evolution of lighting that has today reached the stage of incorporating smartness. “Lighting initially was limited to incandescent, followed by gas discharged, and of course, CFLs came much later. Till then, there was no relationship of lighting with electronics and IT as such. But with the game changer technology coming in the form of LED and getting acceptance all over the world, the entire scenario has changed. We don’t now look at metallurgic or ceramic scientists. We don’t even look at people from Physics, but we look at people who are from electronic background. This is the biggest ever revolutionary change that has happened in the lighting industry.”
He went on adding that the lighting industry in India is still at a very nascent stage. “I remember, a decade back the size of the industry was $1 billion. Today, we are $3 billion, and probably, this is because of the advent of LED in lighting. Of the total, 80% of lighting has already has gone in to LED and by 2020, we hope that the industry would be touching a whopping $4 billion,” he anticipated adding that it’s advantage India. “This is because we are the underdeveloped nation and our pace was not compared with the developed countries. The market size of small European countries was much bigger than us. But more is going to change in the near future because India is at that level where the growth of infrastructure is growing at a very high speed owing to the rapid urbanisation, which changing the landscape of rural India.”
He further pointed out that the change or the transformation now has been much faster than what it was during the 70s when sodium vapour technology was introduced. “Unlike sodium, LED took least possible time i.e. just four years to transform more than 50% lighting in to LED and rest would soon be converted. All thanks to the government and the EESL for their unparalleled efforts in accomplishing the task. This was not it but by projecting the transformation of 770 million LED bulbs plus 30 million streetlights could help indigenous manufacturing to touch a new high – both in terms of quality as well as capacity. This is not it as another 30 million units are coming up with the projection of new roads and highways in the pipeline.”
Industry’s Lightening Stride
Taking the discussion to the next level, Shyam Sujan, Secretary General, Elcoma first explained that Intelligent Lighting Design refers to the advancement in the lighting system, which with the advent of LEDs has become foreseeable as lighting products are now tailored or rather customised based on the particular application. “We added design as the LED is different from all earlier lighting sources, which had limitations with their standard shape and limited applications, while LED is not restricted. It is not only suitable to domestic/commercial/ industrial illumination, but has opened doors to various other applications.”
According to Elcoma, Rs. 22,000-crore Indian lighting industry is expected to reach to Rs. 27,000 crore by 2020.“Today, we have around 50% of total lighting converted in to LEDs, which by 2020 would be touching 80%. This fact advocates that we have to enhance our concentration especially in the manufacturing part of LEDs,” suggested Sujan emphasizing that Elcoma is very pro-active in helping the industry grow, be it in terms of bringing in new technology or enhancing capacity of the industry as a whole.
“It was only a few years back that we built a capacity to produce 1 billion CFLs. Today, the entire CFL producing capacity is convergent in to LEDs, especially the bulbs to meet the demand from domestic sector which is on a steep high. Following the EESL’s national plan DELP, we together were supposed to deliver about 770 million LED bulbs for domestic usage by 2019 and I am very proud to mention that we already have met the target much before the set time frame. We are now eyeing at around 1.2 billion LED bulbs, which would ultimately help us save around 1000 MW of energy from domestic sector alone. The energy consumption in lighting at present is around 18%, which would come down to 13%, once we meet our target.”
Going forward as per the plan, soon all lighting in the public domain would be intelligent lighting starting from the proposed 100 cities. “With intelligence incorporated,the poles would not only be throwing lights from the top of it, but would sport a billboard for advertising, occupancy sensors for need-based illumination, security camera to work as a watch dog, and WiFi connectivity to report the fault as well as the systematic energy consumption chart. This is a task that would be accomplished by the industry in coordination with the government and EESL,” underscored Sujan.
He further highlighted, “While accomplishing our goal of installing or replacing 30-million streetlights, we tried completing the set task in a hurry without even evaluating the viability of the existing infrastructure. Also, the workforce we hired for the job was not trained on installing these LED streetlights, which resulted in 30% failure. But anyway, we learned from our mistakes as we are gearing up for illuminating smart cities with a rather fail-proof intelligent lighting system. At the moment, there are 13 such cities in priority, which are to be illuminated with these intelligent smart lighting.”
Government Initiatives and Industry’s Efforts
Acknowledging the efforts put forth by Elcoma for creating awareness, Venkatesh Dwivedi, CGM (Technical), Street Lighting National Program (SLNP), EESL, expressed his gratitude, “We are thankful to Elcoma for all its hard work. We are very sure that whatever limited success, we have achieved is only because of the lighting industry’s belief in us to take forward this important task. In the last four years that EESL has been carrying out various initiatives, two projects are very important i.e. DELP and SLNP as there were concerns about the success of the programme and if it would be good or bad for the lighting industry.”
He further added that it looked as if these steps put the lighting industry on a price war. “But as time went by, especially over the period of last couple of years, the industry learned a lot from all the projects and experiments that EESL initiated. In the matter of just two years, we could see that how much transformation has been noted within the EESL’s procurement domain as well as outside in the market. After acting as a catalyst for one and half years, we were able to trigger a much bigger change than it was anticipated,” said Dwivedi.
According to him, there were quite a few takeaways from these initiatives of EESL for the industry as the price pressure would not have been that much clear if the industry could have continued interacting with the market directly. “And whatever sacrifices the lighting industry could make in pricing were more on a compensatory side as many new opportunities were created and new plants were setup. We can very much observe that the industry is able to derive a good price outside the EESL domain and has learned from whatever projects we have done till date. This resulted in the large business opportunities with market transformation. With all this in hand, we felt that we have done our job at least in that segment. And there is no denial of the fact that we have secured same level of success in the streetlights also.”
He emphasised that in the streetlight segment there has always been a discussion on how to control the prices and how to get more out of it. “From day one, EESL has been pitching the streetlight segment to key decision makers as lights with individual lamp control. However, we were not able to actually deliver such solution because unlike the DELP, in SLNP the price was bigger barrier followed by the ambiguity in selection of the technology to be adopted for individual or group level lamp control solution whether it is CCMS, GSM-based, RF/ Zigbee or a combination of these.”
“For all this, if anyway, we would have tried to do without consulting the lighting industry, we don’t think it would have been so successful either in the bulb or streetlight segment. Although for group control, adoption has been implemented long back, and almost 2 million streetlights have already been put under the group control. But the time has come now to take the first step in the smart cities solution to the individual lamp level control. Once the technology is proven and rolled out, it would be the first step towards the smart cities concept. It would be the way to bring forth other services including WiFi or there are so many option that one can choose from,” shared Dwivedi.
“At EESL, we have been working with the Elcoma in coordination of which a committee has been set up to evaluate various technologies to find out the most appropriate and the best one. We are yet to reach a conclusion on this front. If we look at the current progress on the project, of the total number of streetlights i.e. three crore, we are in process of installing one crore streetlights by the end of 2018-19. We believe that we would be able to achieve another 50 lakh streetlights in the next one year. This brings a very important point that whatever lights that are already installed by EESL or by any other company, there has to be a seamless integration at the maximum level,” he insisted.
“Based on the discussion on this issue that we have had with the lighting industry, there are two different solutions for the lights – one which is already there and another solution for the lighting that we are going to come up with. There is already 20-30 million streetlights are on the roads across the country. We know that this number is going to double in the next 10-15 years owing to the tremendous development in the pipeline. We, therefore, need to strategically workout on how do we implement the lamp level control in the Brownfield projects and in the Greenfield projects, the carrier that we are going to use, the standard that we need to follow, and the testing protocols that are to be adopted? All to make sure that which ever be the solution is going to come up, should have to be robust and reliable till its projected lifetime,” commented Dwivedi.
The Analysis of Support
Adding further depth, S. K. Marwah, Director/Scientist ‘F’, Ministry of Electronics and Information Technology, said, “LED-based lighting technology has improved dramatically over the past decades. On account of enormous progress made in the field of LEDs and for their energy efficient &eco-friendly advantages, LED-based lighting system has revolutionised the lighting process across the world. We already know that the LED lighting market in India is projected to grow at 4 billion and is growing at a CAGR of over 32%. Presently, the outdoor lighting of the LED lighting sector is the largest revenue generator on account of growing demand from LED activation in streets, automobiles, communication signage, etc. However, the indoor segment is expected to witness strong demand owing to strong awareness campaign on the LED technology and various government initiatives to subsidise the cost of LEDs.”
According to him, with a relatively low penetration and huge untapped opportunities, the Indian market is showing impeccable growth potential for both Indian and international LED players. “The market has been witnessing a very strong trend over the past five years and the same is expected to continue. The current market conditions have created the needed competitive environment among the manufacturers. Adding to it is the demand aggregation by the EESL that has played a significant role in bringing together the manufacturers and promoting manufacturing on large scale,” stated Marwah.
He further emphasised that LED products have emerged as one of the important verticals of electronics. “Overall electronics manufacturing has grown from 1,90,000 crore in 2014-15 to (estimated) 3,87,000 crores in 2017-18. Electronics has been growing at 28% year-on-year during the last three years, where electronics for LED products has been growing at 45% which is much more than that of overall rate. The production of electronics has increased from 5,000 crores in 2015-16 to 9,600 crores in 2017-18 for LED lighting industry. This rise in the electronics manufacturing is a result of various policy initiatives taken by the government and the efforts of the industry. Based on this development, we have observed that the growth is tremendous. Last year, we recorded the growth rate of imports of 4.6% less than half the rate of previous year i.e. 9%. More demand for electronics in domestic market, which is growing at the rate of 19% is met out with the domestic production.”
“Internet of Things is a platform that is emerging and enabling us to control the entire outdoor and indoor lighting in to one control tool. And we can now control our lighting operation from anywhere in the world even through smart phones. Remote switching monitoring and control system provides most effective intelligent controls and high energy savings with proven ROI whether we retrofit the existing fixtures or integrate any futuristic technology.”
The MeITy has taken several policy initiatives towards the promotion of design and manufacturing of LED products. These include incentives under the modified special package scheme, support for setting up of electronics manufacturing clusters, compulsory registration order for compliance of safety standard, support for skill development, etc. Further we have also modified LED products under the public procurement order preference to make in India notified by the department of industrial policy and promotion.
“We are also in process of extension of the phase manufacturing program, which has been a success in promotion of indigenous manufacturing of mobile handsets, to the LED lighting sector. We look forward to the industry and Elcoma for the needed support and coordination. We are also in the process of revision of the National Policy on Electronics that was devised in 2012. We have already taken the inputs from the industry and we still seek inputs from the industry on continuous process. The way we perceive lighting has changed. The sheen of lighting has changed. Today, we can set the lighting as per our mood. Streetlight is emerging as the streetdogs. I believe that in time to come the urge in the departments to give special efforts to incorporating IoT, we can see altogether a different lighting world in the making,” he assured.
Throwing lights on how companies perceive the intelligent lighting, Uma Lanka, Associate Vice President – Design Technology & Business Development, Crompton Greaves Consumer Electricals Ltd., elaborated, “Smart has become very common these days – anything and everything that we see and talked off today as being very smart. But the big question is what is the smart lighting that we see has got to do with the intelligence? In what are the various applications that it can be used and how do we see the next era coming up in this field of intelligent lighting?”
She put forth what exactly we mean by intelligent lighting! “Obviously, intelligence is related to the human intelligence that includes right from the understanding, to self awareness, to communication, to having an emotional knowledge, to reasoning, to problem solving capability, and so and so forth. If we imbibe some aspects of these in to the LED devices so that we are able to come out with many mundane tasks that are being done or higher level of intelligence and that can restrict accidents from happening. Or we can control things in such a way which would not have been possible manually or physically for the human being.”
She opined that the credit of this advancement goes to the advent of LED, which is nothing but a semi conductor device and allows to be controlled just like how each and every electronic device can be controlled. “Why is this intelligence needed? This is because we want to leverage this particular aspect of LED and derive benefit out of it. The possible benefits that could be there are ease of use, resource productivity, trust-building, etc. Once we are able to incorporate a very robust and reliable element of control or monitoring into the devices, these devices can play a very important role. Of late, it has also been found that lighting plays a very important role in terms of how the emotional productivity of a particular human being really affects? How does a human behave?”
“So, starting from visual comfort to energy efficiency to connectivity to internet of things, etc. are all important basic benefits that we want to avail from LED lighting through various applications that include right from home to office to commercial complexes, to public spaces, to hospitality, healthcare, education, retail, monuments, or any kind of architectural structures or buildings. Especially, a country like India, where energy is already deficient, we can make good use of these techniques. For all these areas of applications, the basic aspect of intelligence would be the same. Factors like consumption scalability, fault reporting, artificial intelligence, digital communication, automatic controls, etc. can be incorporated,”explained Lanka elaborating the possibilities attached to it.
Lighting for Modern Workplaces
Akshay Rawane, Senior Manager, Bajaj Electricals Ltd. presented a rather interactive session when he put forth a question to the audience as what do they understand by being smart? “Smart refers to something that is communicable through various means like humans, logic or system, sensors, etc. to make instantaneous decision on-site. Lighting, of course, matters,”he said suggesting that workplace lighting is the new decision drivers. “Since ages, we are talking of various deficiencies of lighting like under or over lighting, glare, human comforts, etc. – all these are hygiene factors. But there are issues arouse due to technological advents, which are now influencing decision makers to think about new factors. Technology talks of human-centric lighting, which is very important with LEDs and electronics coming in to the picture. It is allowing us to explore the picture in a much greater way.”
According to him, in case of workplaces various lighting research foundations have found out that better lighting by mixing the natural daylight with artificial one has been directly linked to the reduction of 15% absenteeism in the workplace. “Office goers’ satisfaction can be positively affected by well-designed illumination. That’s why we see many places are lit differently. We are connected with lighting and we see different places are lit in different ways. This brings forth the potential to building owners and managers to add value, reduce cost, and enhance performance through the application of good lighting alone,” said Rawane.
“Why I said workplace lighting as the new decision drivers? Because, these are advanced lighting systems and pay for themselves by adopting to new working areas as people today do not necessarily like working from their respective desks. It brings additional power in the hands of people enabling them to control, monitor and add to their well-being to enhance productivity. Monitoring has become a very acceptable thing to make it more reliable, sustainable and gather information from all the connected devices to take timely action. We have already started talking about beyond lighting, which means lighting is not limited to illumination but much more than that,” he emphasised.
Rawane also suggested that there is a replacement for emergency lighting, which works on battery power. “And, when battery enters, there comes a pause for charging or for switching over. For this, we can talk of super capacitors with guaranteed life of ten years advocating reliable performance to replace batteries. Most of us use wireless charging, which has now been eliminating the use of wires or cables for being connected. This intelligence can be incorporated at places where there is some kind typicality for ingress protection especially for outdoor and underwater lighting. DC power is also reducing the size of the device. PoE is now entering the lighting segment, eliminating the use of electrical wires, while LiFi – the high-powered connection and data movement is already in the air.”
Connected Indoor Lighting Systems: Optimising Space, Energy & Productivity
Productivity, opined that technology is the best when it brings people together. “We tried to bring solution by integrating arts science and business of illumination to create prolific and productive environment. Lighting simply illuminate the spaces, and now with LEDs, it also vouches for energy saving. But can we imagine a beautifully illuminated space where a light fixture can work as an interface to gather information? The photo-technical flavours of LEDs have induced enough interest among the researchers to create a lighting system where each light fixture gathers information from different entity.”
According to her, this is nothing but a connected lighting system that has become a marketing buzzword to describe a light fixture which has an element of intelligence and connectivity traits. “These lights can report their own energy usage, they can just get switched on if somebody walks by, and they can also tell us that which conference room is available for now. This means optimising space and productivity taking light beyond illumination. But why connected lighting? The indoor connected lighting has huge potential to enhance the quality, save energy and provide intelligent data which can transform the way we live. It can save up to 90% of energy, can maximise the efficiency, and improves the operation. The system allows adjusting the lighting level as per schedule.”
She further explained that how IoT brings forth a platform over which the connected lighting system interacts with other entities in the surrounding. “For instance, communicating with the ventilation system to increase or decrease the performance based upon the number of people in the room. This real time monitoring helps the connected lighting system to make other entities react and reduce their energy consumption at the time of low demand. Further, LEDs have the potential of dimming and facilitate with colour options for soft light to cool light to help the users personalise the experience with different recopies of LEDs to suit different requirements of space and tasks delivering the need-based lighting.”
Khera also highlighted that how the connected system provides human-centric lighting that monitors and enhances human health and functions to different kinds of lighting. “All this provides us the data, and the data management system in the connected lighting can lead to tremendous reduction in energy consumption by tracking and monitoring, in turn taking measures to reduce the energy consumption through power conditioning and control. All this data is actually very important for the facility owners and managers to think how it can further improve the usage of power besides helping them to future forecasting on operational expenses and do financial planning.”
Delving on how the technology works, she elaborated, “By providing the elements of intelligence in the lighting system, we are not just controlling lights but we are widening the scope of communication between different entities. This system is sensor-based where every light is connected with the sensor, which senses three things – temperature, brightness, and presence. The system is then connected to an entity called the smart engine, which can control 48 sensors/lighting units. All these smart engines are connected to smart director, which can talk to 20 smart engines. This system can be further integrated with many other facility management systems for more control & monitoring.”
Highlighting the power of Ethernet, Khera said, “Nowadays, with LEDs coming in to lighting, it is possible to supply power through Ethernet as the electricity requirement of LEDs is very low. This aspect, therefore, reduces the complexities of wiring system as the data and electricity can travel through the same carrier using same the smart engines. There can be any platform. This whole system of connected number of apps. For instance, energy app indoor lighting can be configured in an APP can take you to the lighting control system form, which has access to the available data talking about the occupancy, temperature, energy saving, ventilation, etc. Similarly, we have space app, productivity app, etc.”
Street Lighting Controls – Opportunities & Challenges
Moving ahead, Ranjit Singh, Associate Vice President, Surya Roshni Ltd. shed some lights on how and why lighting controls and monitoring has become a must now. “With so many functions attributed to lighting, the lighting controls & monitoring has become inevitable. As we all know, lighting consumes 18% of the total electricity consumption. The environmental impact of lighting as measured is 1kw energy consumption releases 0.92 kg CO2 in the atmosphere. Further, approximately 2/3 of all the lighting installed globally based on older, less energy efficient technology, which indicates quite a huge potential and opportunity for the advancement of the system. However, people have started talking technology for lighting as there has been a revolution in lighting during past 5-10 years. Switching from the older lighting system to the futuristic technology-based lighting will bring huge saving in energy cost & CO2 emissions.”
Singh pointed out that when we explore the historic evolution of light sources, we found out that right from the incandescent to halogen lamp to HPMV/HPSV lamps to T5/T8 tube lights to CFLs to red LEDs to white high-powered LEDs to LED dimming control and monitoring, the objective for this whole transformation and switching over to the next improved system has mostly been the energy saving than any other factors on-board. “And need of intelligent smart lighting is nothing but the next level of development that was awaited. It facilitates automatic monitoring and control of lights, reduces the electricity bill, gets to know the status of installed lights, lowersthe maintenance and operational costs and last but not the least is that it brings a solution with better ROI.”
Adding further on the issue, Singh explained three main control and monitoring tools – Central Control Monitoring System (CCMS), Wired Dimming Controls, and RF-Based Lighting Controller – that can be used as per the need and suitability of the available system. Referring to a few installations, he elaborated as how group control and monitoring system based on GSM /GPRS/ 3G/4G/ or an equivalent proven technology, installed in a feeder or central switching point for remote monitoring and controlling group of street lights have been successfully delivering the desired results.He reiterated that for intelligent lighting through remote monitoring software, we can easily control lamps (group or individual), schedule tasks, collect data &prepare analysis reports, based on which the system can send alerts for events.
While speaking on such an important and extensive area of lighting, Singh highlighted a list of bottlenecks coming in the way when it comes to switching over to the intelligent and smart lighting system. He pointed out that there are a few challenges in the form of non-availability of GPRS signal, lack of ways to combat power pilferage, ambiguity in selection of control system / technology, installation of lights & equipment, and most important is the absence of needed infrastructure that can withstand the technology advancements now, and in time to come.
Dynamic Façade Lighting
Susanta Bhowmick from Osram Lighting, opined that dynamic façade lighting is nothing but the evolution of illumination patterns and how it is perceived by people over the period of time. “Lot of changes are there in the lighting but have we ever thought what these changes are here for? Safety, security, power, lighting, everything was there, but were functional in isolation. Now, we are trying to connect them. We are just adjoining them to avoid going to various vendors for different requirements. People nowadays do not love to go to various lighting providers, but look for solution or service where the solution provideralso takes the responsibility to maintain the installation and functioning of the system for certain years afterwards. And this is important to design a fail-proof system or if it fails there should be minimum errors and can be rectified in very little or almost no time.”
His opinion on lighting was a bit different from the league. “What is the importance of the dark, starry night time sky? The job of lighting is to glorify the darkness and not simply illuminate the spaces,” Bhowmick added that for creating or developing design of facade lighting, the need is to ideate to deliver the message through lights. “For this, we have to define a concept first by defining the event. We should not consider lighting as smart. We need to think that how lighting is to be treated to make the space smart. This is how we can create or develop interactive façade lighting, which can further be improved with the advancement in the display technology, accommodating the presence with accountability for holding on future.”
Smart & Intelligent Lighting System
Gaurav Bhalla, Deputing General Manager Lighting COD, Jaquar Lighting, feels that lights these days are being made to react through IoT. “From those traditional wired network, we are now travelling to wireless network. Nowadays, LEDs are in huge numbers. Even though we are the third largest producer of electrical energy, we are the third largest consumer of it at the same time. The goal is ultimately to have power for all. So whatever, we can save by changing over to LED that again a kind of contribution to a world which is power-starved.”
According to him, starting from smart phones to consumer electronics to PCs to other electronic devices, etc. all have been developed over the last 10-15 years and every single year, the number of these devices is doubling. “We now have smart homes wherein all the devices are connected to each other.Today, we are switching over to low-cost devices and everything has become commercially viable. So many software and hardware have been growing like anything to which customers are showing very positive attitude.New technical developments are happening almost on daily basis.”
“We are now developing systems, which are compatible with the existing infrastructure. All these are helping LED lighting to penetrate deeper with every passing day, where main drivers are comforts attached to it be it safety/security or smart home automation. All are connected through IoT and can be controlled from anywhere through smart app.All the devices are coming up with standard IPs, which are connected through www and we can operate it from one hand. We can connect any number and any kind of IT-enabled device,” said Bhalla.
He further emphasised that smart street lighting system comes with a lot of features like environment sensors, billboards for advertising purposes, security cameras, EV chargers, Wi-Fi system along with the lighting. “These are the basic parameters on which the smart city concept is working. It will provide an ease of installation. There won’t be any complex wiring involved but on simple cable network the system can remain connected through Wi-Fi. Advertising would become easier because of the precision of billboards. Now gradually we are switching over to electric vehicles, so the EV charging would be required. Security cameras are to be monitored at a centrally located place, etc.”
Bhalla advocated that individual or group control of streetlight luminaires would be there simply by sitting at a central control monitoring system based on the RF system. “The RF network can communicate with each other through the mesh networking technique enabling communication among a few nano cities would be possible. Any level of dimming of these lights is possible according to the setting of the daylight. All this is controlled by majority of sensors, which can help us 70% lighting energy. Daylight harvesting in combination with the dimming control can help us save extra up to 30% lighting energy. Various kind of customised setting is possible through these sensors depending upon the specific requirements,” he said.
In the final presentation, Rahul Sharma, Deputy Manager (Tech.) at EESL, highlighted how we can seamlessly incorporate intelligent controls in the streetlights to be installed under the Street Light National Program (SLNP) across the country, which can be replicated or further improvised if so needed for the projected smart cities. “So, what is a Smart City?A smart city is a municipality that uses information and communication technologies to increase operational efficiency, share information with the public and improve both the quality of government services and citizen welfare. Smart city concept broadly covers five major sections energy management, urban mobility, water management, waste management, and e-governance/citizen services.”
He also highlighted the challenges in the way to creating a Smart City. “We need to improvise the basic infrastructure at the ground level to make it compatible for smart technologies. New innovative models with operational flexibility should be put in place. For smooth progress of the projects, there should be the provision of proper financing without any break. Besides, there must have been an on-going capacity building program to keep feeding the project on continuous basis or as and when required so that the project should not go on a halt for the lack of resources,” elaborated Sharma.
For smart cities, he suggested that Central Control & Monitoring System (CCMS) could be a possible solution both at group level and individual level bringing transition in the country’s lighting infrastructure. The CCMS facilitates automatic switch off &switch on as per programme, provides dimming of individual or group of lights at late night as required, establish communication of each pole or group of poles with central control room. Besides, recording of electrical parameters like V, I, PF, Harmonics, etc. & metering of existing consumption would further allow managing or planning for optimised usage. The system also provides on-off status, apart from generating alert during fault. The best part is that it can be integrated trough Online, Mobile App, Toll-Free Number for complaints registration for an automated future.”
The way industry is prepping to incorporate the intelligence in lighting, it is aptly imperative that the country’s lighting system is on the verge of a revamp due for so long. All the stakeholders are seemingly happy to embrace the change indicating that the intelligent lighting design is in the air across the lighting fraternity of the country, and soon the much-hyped high-tech lighting system would be seen functional in India.
In short, the conference was a big success with quite a few takeaways for each of the 200 attendees who came to listen to the industry experts through their respective lectures/presentations followed by demonstration of the technologies – both indoors and outdoors, got something or the other for themselves. Elcoma thanked all the delegates and sponsors for their support without which it would not have been such a success.
