IR 940nm LED Emitter 2016 SMD LED

Is 940nm IR Visible?

The color of LED changes all the time with the wavelength gets longer. As we know, the 365nm LED will be like purple color and then deep blue(450nm), water blue(470nm), ice blue(500nm), green(520nm), yellow green(570nm), yellow(590nm), orange(600nm), red(625nm LED). The color will be red since 625nm. After that, the color will go deeper and deeper until it's invisible. Even the LED still working. The color of 660Nm LED will redder than 635nm LED. When it go with 850nm LED, the color will still be red, but it will dimmer than 635nm LED. When we check on the 940nm LED, the light will be extremly dim and our nake eyes can not even see it work if we just light up a small power 940nm LED like 0.06W 940nm IR LED or 0.2W 940nm IR LED. But when the power go higher, such as 3W high power 940nm LED, it will be able to see a small dim spot in the chip. 

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.
