What is COB LED ?
COB, (Chips on Board) , multi LED chips are packaged together as one lighting module.
Cob LED Light Source is a High efficiency, integrated, surface light source technology that mount the led chip on the high reflective metal substrate.
This technology without the conception of holder, no plating, no Reflow soldering, no patch process, reduce the 30% process, so it also cuts down about 30% cost.
Driverless 50w led chip feature
A1:MOV for surge protection>4000V passed
A2:1000V Bridge rectifier
A3:Constant current and constant power control
A4:NTC sensor for pcb overheat protection
A5:Voltage-regulator for ic vdd protectio
A6:Driver IC, over voltage and over current control
A7:It can use led dimmer or SCR dimmer to dimming it
Advantage of led chip board
1. LED chip is fixed on the aluminium layer of PCB, the heat can be spread out through aluminium layer rapidly.
2. Low light decay: decay rate is less than 2% after 10000 hours and less than 30% after 35000 hours.
3. Equable and soft irradiancy, no glaring and eye protection.
4. Good reliable, no dead bulb, no dark space, uniform spherical scattering.
5. COB LED encapsulation lighting can be multi-functionally used in variety lighting products.
6. Highly color-rendering index and lighting effect, no ultraviolet and infrared rays, no attraction to mosquitoes.
7. Low voltage work to ensure the products safety used.
8. No contain mercury, lead and other heavy metals, environment friendly.
