True green, hyper red LEDs target fitness wearables
In true green the PointLED offers greater brightness of 1800 to 2800 mcd at 20mA. 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. The hyper red version at 660nm has a special narrow-band wavelength range that is suitable for measuring oxygen levels in blood, while the true green version with a typical brightness of 1400 mcd and a wavelength of 525nm is suitable for use in pulse monitors.
Both versions of the Firefly E 1608 come in 0.8×1.6×0.6mm package. The PointLED is already available and the Firefly E1608 is available for first customer projects. Volume start-up is planned for the early 2017.
