What is COB?

There are basically 3 LED configurations:

LEDs in cylindrical packages

SMD LEDs (Surface Mounted Device)

COB LEDs (Chip On Board)

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.

Advantage of COB?

1, less thermal resistance .

Among different LED components such as high power LED, SMD, dip etc, COB LED is the best in less thermal resistance and cooling.

For high power LED, the total Thermal Resistance are a. LED attach, b. Slug, c. Epoxy, d. PCB

Thermal Resistance: A+B+C+D

But for COB LED, are only . a. LED attach + d. PCB.

Thermal Resistance: A+D

So the COB LED is less thermal resistance, so the heat generated from LED chip can conduct outside quickly. Then assure the LED has long lifetime and high quality.

2, larger cooling area for LED chips.

3, Better light effect,No glare,protect eyes.

4, higher light efficacy.

Application of COB Technology

1, COB LED light sources

2, LED lighting fixture which use COB LED light source
