Taiwan’s Industrial Technology Research Institute (ITRI) displayed adjustable spectrum LED lighting that conforms to circadian rhythms at the 2018 Taiwan International Lighting Show (TILS) which was held in April. Basically, ITRI is assisting local lighting manufacturers in determining untapped growth opportunities.
The ‘LED Lighting and Health’ pavilion highlighted adjustable spectrum LED using multi-chip multi-colour module design. Specific wavelengths can be mixed to form white light to provide the human circadian rhythm health effects. The adjustable spectrum LED lighting module developed by ITRI provides white light with the same colour
temperature as seen by the eye, but the ratio of red, blue and green light is in fact different. This consequently leads to different amounts of melatonin inhibited by light and eventually impacts one’s day and night perception unwittingly.
Chih-I Wu, ITRI’s VP and general director of Electronic and Optoelectronic System Research Laboratories said that the increasing maturity of the LED technology is gradually expanding the scope of applications in the LED lighting market. Contrasting with the past when the LED lighting R&D centered on enhancing efficiency, focus nowadays tends to be more on raising the added value, he said. In practical terms, this marks a transition from “technology R&D centering on lighting alone” to “system integration and smart applications.” Taking an office setting for, example, efforts today are designed to make lighting comfortable and energy efficient, while at the same time ensuring worker efficiency and health.
According to Wu, ITRI is hopeful to combine its strengths in LED and ICT together with new ideas to aid Taiwan’s LED industry escape from immense competition that is engulfing much of the sector. Also, set its sights on untapped Blue Ocean opportunities in order to grow big.
