Some Information about China COB LED Down Light:
LED (light emitting diode) is new technology with advantages of saving energy and very long lifespan. But all LED lighting source can not be faultless especially SMD, HP, FULX, etc. COB is multi-chips packaged, it can 10 times more increase lighting area, so it avoids uncomfortable glare by the maximum extent. By now, for small size chip, some famous LED chip manufacturer can reach 249lm/watt @ 20mA. But big size LED chip can only reach 161lm/watt @350mA. The light efficacy decrease when chip size is bigger. Also when LED driver increase current to LED, the light efficacy per watt is even low
The COB with small size chips will be a trend of LED light source package.
