Osram Opto Semiconductors has added new versions of the PointLED and Firefly LEDs to its portfolio for use in mobile applications such as fitness tracking and health monitoring.
The Firefly E 1608 in hyper red has a special narrow-band wavelength range around 660 nm so it also offers optimized signal recognition. It is suitable for measuring oxygen levels in blood, while the true green version is ideal for use in pulse monitors. Both color versions of the Firefly have the advantage of compact dimensions, giving customers greater flexibility in designing their products.
In true green, the PointLED offers greater brightness of 1800 to 2800 mcd at 20 mA. In fitness trackers it provides an improved signal with a higher output compared with earlier versions. This means that it needs less energy to produce the same signal as its predecessors, which in turn enables the battery to last about 50% longer.
In addition, the hyper red version at 660 nm has a special narrow-band wavelength range that is ideal for these applications. The true green version has a typical brightness of 1400 mcd and a wavelength of 525 nm. Both versions of the Firefly E 1608 have a small package of only 0.8 mm x 1.6 mm x 0.6 mm.
