100 lm/W 80W CE RoHs certification 220V SMD 2835 LED DOB driverless led square pcb pcba module for LED Streetlight 

Product Featured In

1.Linear constant current IC control, photoelectric integration design with stable performance, high reliability and long lifespan.

2.Over-voltage & over-current protection.
With optimized constant power IC design, when input voltage varies between AC 220 and 240V, the IC maintains constant power output within ±5% fluctuation range to protect the module from over-voltage and over-current.

3.Over-temperature protection design.
When the PCB rises up to a very high temperature after running for some time, the patented technology IC will automatically reduce the output current to control the temperature rising of the PCB.

4.High quality EMC 2835 LED with high color rendering index. Ra > 80. No concern in ultraviolet ray or electromagnetic radiation.

5.No EMI.
The module meets qualification standards of certification such as CE-EMC, CE-LVD, SAA, RoHS, PSE and UL.

6.Custom design and Manufacturing.
Customized service is available for custom PCB shape and size design, custom color temperature, custom LEDs and so on.
