Infrared light emitting diodes (ir) are made of high infrared radiation efficiency materials (commonly used gallium arsenide GaAs) to produce PN junction, plus forward bias to inject current into PN junction to stimulate infrared light.The spectral power distribution is 830 ~ 950nm of central wavelength, and the half-peak bandwidth is about 40nm.Its greatest advantage is that it can be completely free of red storms (using 940 ~ 950nm wavelength infrared tubes) or only weak red storms (red storms with visible red light), thus extending service life.Light is an electromagnetic wave whose wavelength ranges from a few nanometres (1nm=10-9m) to about a millimeter (mm).The human eye can see only part of it. We call it visible light. The wavelength range of visible light is 380nm ~ 780nm.
Generally, infrared emitter tube wavelength is 850nm, 870Nnm, 880nm, 940nm and 980nm
Relationship between power and infrared emitter wavelength: 850nm>880nm>940nm
Peak wavelength: the energy distribution measured by the luminator or object on the spectrometer, and the corresponding wavelength p at the peak position.
Radiation intensity (POWER) : unit mW/sr, denotes the size of IRLED radiation infrared energy.
The radiation intensity (POWER) is proportional to the input current (If), and the radiation intensity is inversely proportional to the transmitting distance.Unit mW/sr: unit of infrared radiation intensity, which is the power of light emitted by unit solid Angle (sr) of infrared transmitting infrared light.Artificially increasing the power of the infrared transmitter can only temporarily increase the irradiation distance, and finally the decay of the crystal circle is accelerated, causing the infrared lamp to become darker and the night vision to become less and less clear.The external light source in the irradiated environment is complex, and the infrared camera leaf can not play its due effect.Transmitting distance, transmitting Angle (15 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, 180 degrees), transmitting light intensity, wavelength.These are physical parameters.
