Short Wave Infrared LED 1550nm High Power 2835

What is SWIR LED?

SWIR LED is the abbreviation of short wave infrared LED. In general, SWIR is the LED have wavelength between 1 and 2.5um. Then why some people also name this 1550nm or 1500nm LED as far red IR LED or long wavelength ir led? To sum up, long and short are relatively compaative conclusions. Such as, compare with 660Nm LED, this 1550nm LED will got a longer wavelength. That's why for the long wavelength. Back to the SWIR, it's on the boundary between visible and thermal imaging. It's report that this light field has unique properties. If you need some 1550nm LED for your project, just feel free to contact us for more detail about it. 

1550nm High Power LED 2835 SMD LED Size: 

* High Power SMD LED are also available in 940nm LED, 850nm LED , 730nm LED and some Far red infrared LED *

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.
