Revert to Infrared LED light
Infrared LED light is an electromagnetic wave,The wavelength has a range of a few nanometers (1nm=10-9m) to 1 mm (mm).  a part of one’s wave band that It is a visible light in the human eyes.we could call it into visible light, visible light wavelength range of 380nm ~ 780nm, visible light wavelength from long wave band to short wave band divided into red, orange, yellow, green, cyan, blue, Wavelength is short than purple, we called it Ultraviolet rays . avelength is longer than red we called it infrared light.

Infrared light Applications：
The infrared led have a long historical standing. Uses. In 1962, People discovered how to form the Electromagnetic wave of infrared ray(using on GaAs on behalf of the III V compound semiconductor PN node that it could be phenomenon of Electromagnetic wave).The infrared led were used to . AlGaAsP class GaAs semiconductor materials to generate infrared ray , The forward voltage of ir led strip is about 3.3V.Ir emitting infrared ray. In generally refers to luminescence center wavelength of over 700nm LED. Much as a remote control and infrared light communication, distance sensor light source, a light source and a printer opt couplers hand piece light source etc.
