Characteristic of ir led emitter

With the progress of science and technology, the level of industrialization has also been improved, now high-tech products have been used widely, we believe that for infrared emitting diode will not be unfamiliar, infrared emitting diode that is capable of emitting infrared diode, the more common is applied to remote control and other occasions. Is widely used in our daily life, here we will to recognize the infrared light emitting diode model and the principle of work, hoping to serve as a reference.the shape of the infrared light-emitting diodes and light-emitting diode (LED) is very similar，to emit infrared light. Infrared light emitting diode in the pipe pressure drop is 1.4V, operating current of less than 20mA. Infrared light-emitting diodes are designed to adapt to different working voltage, the circuit is often with the limited resistor. Infrared light-emitting diodes emit infrared to control the controlled device controlled device emits infrared light, corresponding to achieve the purpose of control. The following we will be familiar with the infrared emitting diode models and principles described.
 Application Parameter：
Infrared light-emitting diodes are made of high efficiency infrared radiation material PN junction,to stimulate the infrared.Infrared light when inject current to bias the infrared. Infrared light emitting diode spectral power distribution as the center wavelength of 830~ 950nm, half peak bandwidth around 40nm. Infrared light emitting diode in use, the biggest advantage is that you can complete without red storm, or only faint red storm so that its life is greatly prolonged, the light is an electromagnetic wave, the wave length range from several nanometers to about 1 mm. In our daily lives to see only one part, called the visible light wavelength range is 380nm ~ 780nm.
