3W Green High Power LEDs 520-530nm High Lumen

What is high power LED? 

For those SMD LED that we name as 3014 SMD LED, 2835 SMD LED, 2016 SMD LED ect. They are all small power LED normally because their will just have the power like 0.06W, 0.1W, 0.2W or 0.5W. In this 8080LGC52D45I1A, the power can reach more than 1 watt and it can even handle 700mA for each LED. If the LED can dissipate 1 watt or more of power like 2 watt even 3 watt, we will also name this LED as high power LED. They have a good performance of heat dispersion so that we can put a big chip inside and high temperature won't hurt the LED in this case. 

High Power SMD LED Size: 

Electrical Parameters:

*Pulse forward current confition: Duty 1% and Pulse width=10us.

*Soldering confition: Soldering confition must be completed with 3 secongds at 260℃

*Luminous intensity is measured by ZWL600.

*λD is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.

HANDLING PRECAUTIONS:

Compare to epoxy encapsulant that is hard and brittle, silicone is softer and flexible Althouth its characteristiec significantly reduces thermal stress, it is more susceptible to damage by extemal mechanical force. As a result, special handling precautions need to be observed during assembly using silicone encapsulated Led products. Failure to comply might lead to damage and premature failure of the led

1. Handle the component along the side surfaces by using forceps or appropriate tools.

2, Do not directly touch or handle the silicone lens surface. It may damage the internal circuitry.

3, Do not stack together assembled PCBS containing exposed LEDs. Impact may scratch the silicone lens or damage the internal circuitry.

4, 4-A The inner diameter of the SMD pickup nozzle should not exceed the size of the LED to prevent air leaks;

    4-B A plible material is suggested for the nozzle tip to avoid acratching or damaging the LED surface during pickup.

    4-C The dimension of the component must be accurately programmed in the pick-and-place machine to insure precise pickup and avoid damage during production;

    4-D As silicone encapsulation is permeable to gases, some corrosive substances such as H2S might corrode silver plationg of leadframe. Special care should be taken if an LED with silicone encapsulation is to used near such substances.

5, Please aviod continued exposure to the condensing moisture environment and keep the product away from repid transitions in ambiemt temperature.

6, Product in the original sealed package is recommended to be assembled within 24 hours of opening.
