Advantages:
1): Sufficient power can replace
traditional light
2): Low temperature inside of light
body.
3): Energy saving, low power
consumptiona
4): Environmental protection, lead
free and RoHS compliant.
5): Low heat, no IR & UV light
radiation
6): Quick & Simple installation,
it is an excellent replacement of conventional
lamp.
Special COB
advantage:
1. Soft light and low sight hazard. By
using new COB LED light source, it is very good for human eyes
due to the even lighting surface.
2. Long Life Span. Combine the
advantage of COB LED package, our lamp have very good heat
dissipation and its life span could reach more than ****0
hours.
3. Stable performance. Rational
structure design and constant current driver ensure the products’
stable performance.
4. Environmental friendly. No hazard
materials occur when lighting.

lighting
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 *0 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 **9lm/watt for *0mA. But
big size LED chip can only reach **1lm/watt for **0mA. 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
