High power COB light source in application
The cob plate light source is light production as save power and friend environment, this integrate led chip packing on the aluminum substrate,
it has a lot of advantage for example , low heat resister, excellent dissipation heat, install convenient , adopting reflection plate surface as make light source soft and have large range of illumination ,no dazzle ,no uv light.

application area
supermarket , indoor, hotel , kitchen ,bedroom ,

Product process of cob chip
Putting the heat conducting epoxy resin covers the surface of the aluminum substrate, then put the silicon chip into the aluminum substrate, the silicon chip firmly fixing the aluminum substrate with heat-treatment,
then cilicon chip and the aluminum substrate build relation of electrical connection using wire welding

Advantage and drawback of high power cob

Advantage
Compare to single LED, the cob light source can save that once packing cost and twice grading cost. the same function in lighting device system,
the cob can cut down 30% cost of light source through actual measure,
this is great important significance to promote COB to application market.
in performance , via reasonable lens design , cob module can avoid dazzle,
in application, the product and install of cob module is simple and convenient, so it can cut down product cost. with the lighting market gradually increase , the cob light source will be mainly production .

The COB packing is more reasonable than traditional SMD packing. the COB packing is that single or various led chip pacing in to aluminum substrate.aluminum substrate for heat dissipation. the COB packing is low heat resister, the low heat resister lit well-distributed is the advantage .so the COB widely applicable to the lighting field

Attentions in use:
static electrical
The COB afraid static electrical, so ant-static electrical is necessary , especially the static electrical is bigger that max specified value. it will damage the cob. the user must adopted a resolution for ant-static electrical,

Welding

The power of welding machine be lower 20W and work temperature of welding machine is not higher than 300℃, the welding time no more than three seconds.

Clean COB
After welding please using ultrasonic to clean the COB
