ON-BBL tunable white COB LED is now available from ZIGEN

Hiroshima Japan: ZIGEN Lighting solution co., ltd. announced an industry’s first tunable white COB LED product ZG7BGXL5W00, which changes luminous color following the blackbody locus (BBL) by 2channel input, is now available. https://zigenls.com/web/product/zg7/

Thanks to proprietary ZIGEN’s patented ON-BBL LED structure, the color range of ZIGEN’s ZG7BGXL5W00 is set from 2000K sunset color temperature, preventing middle color from becoming pinkish.

So far, luminaire manufactures have to take care Duv (deviation from the BBL) in the middle color when designing a tunable white application by 2 channels of warm white LEDs and cool white LEDs, as mentioned in the Department of Energy’s report. (*ref1)

Thus, the color temperature ranges in most of tunable white LED applications are set from 2700K or above, where the BBL is relatively straight.

Tomokazu Nada, CEO of ZIGEN Lighting Solution Co., Ltd., said, “Color temperature range down to 2000K should be necessary for human centric lighting application, considering market success in dim to warm LED and researches in circadian rhythm lighting.” (*ref2)

With the above aspects, ZIGEN is now ready to support ON-BBL tunable white COB LED ZG7BGXL5W00 samples and offer customization to users.
