Classification of light sources
Infrared light source
Infrared light source is a non illuminating electrical light source designed to generate infrared radiation. Infrared radiation is electromagnetic radiation with a wavelength greater than the wavelength of red light in a certain range, ranging from 0.78 to 1000 μ m. It is usually divided into three bands: near-infrared (IR-A, wavelength 0.78 to 1.4 μ m), mid infrared (IR-B, 1.4-3 μ m), and far-infrared (IR-C, 3-1000 μ m). The corresponding infrared light sources are called near-infrared, mid infrared, and far-infrared light sources, respectively. Applied to heating, physical therapy, night vision, communication, navigation, plant cultivation, and animal husbandry.
UV light source
UV light source is a device that generates ultraviolet radiation. Mainly produces ultraviolet radiation, electromagnetic radiation with a wavelength smaller than that of purple light (1-380nm). According to the different wavelengths, ultraviolet radiation can be divided into four bands: long wave (UV-A, wavelength 315-380nm), medium wave (UV-B, 280-315nm), short wave (UV-C, 200-280nm), and vacuum (UV-D, 1-200nm). The corresponding ultraviolet light sources are called long wave, medium wave, short wave, and vacuum ultraviolet light sources, respectively.
Laser light source
Laser light source is an electrical light source that uses excited particles to emit light under stimulated radiation, and has high coherence. The output wavelength range ranges from shortwave ultraviolet to far-infrared. The characteristics of laser light sources are good monochromaticity, strong directionality, and high brightness. Applied in fields such as communication, medicine, ranging, and processing.
LED light source
LED light source, also known as light-emitting diode light source, is a semiconductor light source that utilizes the characteristics of semiconductor materials to generate light under the action of current. LED light sources have many advantages, such as small size, long lifespan, high efficiency, low power consumption, strong safety and reliability, and are conducive to environmental protection. Its working principle is based on the PN junction luminescence principle. When a forward voltage is applied to the PN junction, the holes in the P region and electrons in the N region will recombine, releasing energy that is emitted in the form of light, producing a luminescent effect. The application of LED light sources is mainly concentrated in the field of lighting, such as night scene lighting, traffic light markets, and specialized general lighting, in addition to the display of electrical appliances and devices, instruments and meters, and equipment.
