■ Importance of On-BBL (Black Body Line) technology in tunable white
Actually, the reason of “why tunable white LED in the market all start from 2700K or above” is because light become pink color in the middle CCT range.
As shown above, color change by conventional tunable white LED move straightly between 2 color point.
So, when color range is set from 2000K to 5000K, middle color point around 3000K stay >step 6 away from color target and becomes too pink .
That’s why conventional tunable white available in the market only starts from 2700K or above.
Only ZG7 can provide tunable white starting from 2000K, important color as Sunset color temperature for human centric lighting
■ Why ZIGEN can provide On-BBL COB solution ?
ZIGEN has patented technology in LED structure and using 3 phosphor color by 2 CH control makes tunable white LED able to provide On-BBL color change.
We are planning to adopt this technology to higher power COB and SMT solution in soon.
■ Controlled color quality.
ZIGEN check 3 color point during production.
at both edge and at the middle color.
Also, step 3 control is also no change from standard series.
