Dome Lens SMD LED 555nm Standard LEDs 15-Degree

555nm 560nm LED with 2835 Dome Lens Type; 

Compare with 520nm LED, 555nm 560nm LED have a longer wavelength. Then what's the different of the color? 

520nm LED emits those green LED that from traffic light light. As we know 590nm LED will be Yellow LED. Then the wavelength more close to 590nm LED, the color will be more yellow-ish. Color of 555nm LED will be yellowish than 520nm LED. But it still will be green LED after all. In order to make this 555nm SMD LED have a higher brighness and more focused output, we also added a narrow lens on the top of this SMD LED. If you need some 555nm LED for your project, just feel free to contact us for more detail about it~

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.
