High-power RGBWW LEDs offer CRI in excess of 95

September 16, 2019 //By Julien Happich
YujiLEDS lab has released a high-power LED integrating 5 channels including red, green, blue, cold white and warm white in a 7070 package.

The RGBWW LEDs technology is well suited for photography and film lighting, but is also valuable for any areas that require various colours or CCTs, like entertainment venue or horticulture lighting. White light is usually used as a supplement to resolve the low CRI of RGB LEDs, yet colour fading still occurs when acquiring other CCTs by tuning the spectrum compared to the original white light. Adding a second white light source provides a solution to ensure that all the white light can be achieved at CCTs between that of cold and warm white light, with the same high level CRI (min Ra 95).

The lead frame of the new LED is designed by Yuji to satisfy the requirement of high luminance. With up to 150mA per channel, the RGBWW outputs a luminous flux from 43 to 48lm for white and green, 22lm for red and 10.5lm for blue which are 100% higher than conventional 5050 LEDs.

As well as its standard version of red, green, blue, cold white and warm white, the 7070 LED can be customized with specific colour channels.
