Illumination source

The illumination source is an electric light source for the purpose of illumination, which radiates a visible spectrum (wavelength 380-780 nm) mainly for human vision. Its specifications range from 0.1 watt to 20 kW, and the output accounts for 95% of the total output of the electric light source. the above.

There are many kinds of illumination sources, which are divided into three categories: thermal radiation source, gas discharge source and electroluminescence source according to the form of illumination.

1 heat radiation source. A current that flows through a conductive object to radiate light energy at high temperatures. Including incandescent and tungsten halogen lamps.

2 gas discharge light source. A current source flows through a gas or metal vapor to produce a light source that emits light and emits light. There are two kinds of gas discharges: arc discharge and glow discharge. The discharge voltage has three kinds of low pressure, high pressure and super high pressure. The arc discharge light source includes: a low-pressure gas discharge lamp such as a fluorescent lamp, a low-pressure sodium lamp, a high-intensity mercury discharge lamp such as a high-pressure mercury lamp, a high-pressure sodium lamp, a metal halide lamp, an ultra-high pressure gas discharge lamp such as an ultra-high pressure mercury lamp, and a carbon arc lamp. A gas discharge lamp with a large discharge pressure span such as a xenon lamp and some spectral light sources. The glow discharge source includes a glow indicating light source utilizing glow discharge in the negative glow region and a neon lamp utilizing glow discharge in the positive pillar region, both of which are low pressure discharge lamps; in addition, some spectral light sources are included.

3 electroluminescent light source. A light source that illuminates a solid substance under the action of an electric field. It converts electrical energy directly into light energy. It includes two kinds of electroluminescent light sources and light-emitting diodes.

Fasteners, fastened and used for a very wide range of applications and a type of mechanical parts. Fasteners, the use of a wide range of industries, including energy, electronics, electrical, mechanical, chemical, metallurgy, mold, hydraulic and so on, in a variety of machinery, equipment, vehicles, ships, railways, bridges, construction, structure, tools, equipment , Chemicals, instruments and supplies above, you can see all kinds of fasteners, is the most widely used mechanical basis. It is characterized by a wide variety of specifications, performance, use different, but also standardization, serialization, the degree of generalization is also very high.
