What's COB?
COB, (Chips on Board) , multi LED chips are packaged together as one lighting module. When it light up, it looks like a lighting panel..
Why COB? --Background
LED(light emitting diode) is new technology with advantage of saving energy and very long lifespan. But all LED lightsource can not be faultless especially SMD, HP, flux LED etc. Compare to traditional lighting such as fluorescent lamp, as it is super bright in a small size, it cause uncomfortable glare. In case of no diffused optical lens used, such LEDs usually cause glare and zebra strips . But when optical lens or cover used, it will cause light loss when LED beam pass through this lens or cover.
How COB LED Light source works
COB LED is multi chips packaged, it can 10 times more increase lighting area, so it avoid uncomfortable glare by the maximum extent.
Auroras Lighting uses small size of chips to make COB LED package.
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.
We holds the patent for invention for COB LED and lamp.
No glare,protect eyes.
Application of COB Technology
1, COB LED light sources
2, LED lighting fixture which use COB LED light source
