Mini IR Illuminator Principle

- Jul 12, 2017-

Infrared light-emitting diode (LED) principle Infrared light-emitting body is composed of infrared light-emitting diode (LED) matrix. Mini IR Illuminator Infrared light emitting diodes from the infrared radiation efficiency of the material made of PN junction, plus forward bias to the PN junction injection current excitation infrared light. Mini IR Illuminator Spectral power distribution for the central wavelength of 830 - 950nm, half - peak bandwidth of about 40nm, as shown in Figure 1 (850nm, Mini IR Illuminator 940nm infrared light emitting diode spectrum diagram) shown. Mini IR Illuminator It is narrow band distribution, for the ordinary CCD black and white camera can feel the range. Its biggest advantage is that there can be no red storm (using 940 ~ 950nm wavelength infrared tube) or only weak red storm (using 850nm wavelength infrared tube); also has a long life characteristics.

Light control soft-switching circuit circuit The infrared light using a light-controlled soft-switching circuit to reduce the impact of its working state transition to extend the life of infrared light

Constant current circuit to compensate for the infrared light in winter and summer infrared radiation power difference, the infrared light using a constant current regulator circuit, Mini IR Illuminator the infrared light-emitting diode optical power stability, thereby enhancing the use of infrared light effect, extended use life.

The choice of infrared light and the choice of the use of infrared light The most important issue is the infrared light and the camera, lens, protective cover, Mini IR Illuminator power supply and other complete sets of. Some people have bought a surveillance camera, lens, shield, power supply, and even after installation to consider buying infrared light, which is not correct, Mini IR Illuminator should be in the design of all the equipment when considering it as an infrared low light Night vision monitoring system engineering to carry out the design.
