Introduction
 
The factory, mine production in the assignments section use lamps and lanterns. Mining lamp except in usually use a variety of environment floodlight outside, still have a special environment with the lamp and anti-corrosion, lamps, and industrial and mining lamp used in some large tall buildings.
 
Type
 
According to the function of the mining lamp can be divided into general lighting and local lighting two kinds.
 
General lighting usually evenly in the upper part of the work site layout or lateral wall, lighting the whole face, need to use power larger incandescent lamp, halogen lamp, tungsten high intensity discharge lamp or quantity more fluorescent lamp. Most of the mining of the lights. General lighting distribution of light to have higher demand, widely use direct lighting type and half direct lighting type two types of light distribution, especially the latter. Half direct lighting part of a type of light ceiling light up, can increase the ceiling brightness, create more comfortable, more bright environment.
 
Local lighting is a kind of improving a work place intensity of illumination lamps and lanterns. Its role can be based on the general lighting in strengthening, added lighting, also can be in some usually don't need lighting places (such as equipment repair, maintenance place) as a temporary lighting. Their light without strict rules most of distribution. Local lighting is usually served in the working area near, to use safety, the low voltage (more than 50 V, exchange RMS) of incandescent lamp, halogen lights for the light source of tungsten. Have (portable) line lamp, the lights up, work desk lamp, machine tool work light, etc. In some big factories, sometimes use project-light lamp as local lighting.
 
 
 
Mining lamp light source can be divided according to traditional light industrial light (such as sodium lamp, mercury lamp light industrial mining, etc) and LED light industrial and mining. Than the traditional industrial LED lamps light industrial has great advantage:
 
1 LED mining lamp show means high RA > 70
 
2 LED light industrial high efficiency, energy saving more, the equivalent of 100 W LED mining lamp can replace traditional 250 W of traditional industrial light.
 
3 traditional light the lamps and lanterns of high temperature has shortcomings, lamps temperatures up to 200-300 degrees. And LED itself is cold light source, lamps and low temperature, more safety.
 
4 LED mining lamp in the unceasing innovation, the latest chip radiator fins mining lamp more reasonable design of radiator, greatly reduced the weight of the mining lamps, make 80 W LED mining overall weight light fell to the following 4 KG, and perfect solution 80-300 W LED mining
 
 
 

Use requirement
 
In order to meet different production operation visual needs and the needs of the installation conditions lamps, industrial and mining light reflector should be able to produce all sorts of size degree of light distribution. Surface paint and coating of the present white glaze, and with aluminum, glass mirror, prismatic glass and other material made of reflector, and you can get wide light distribution, suitable for large area, vertical or close to the vertical working place to work. For tall plant and with a tall the need for a separate machine the place of lighting, can use the prism glass, glass mirror polishing aluminum and control performance of strong light material made of reflector, and get the narrow beam distribution.
 
For in the more dust, moisture and other environmental conditions of poor place long term and working reliably, industrial and mining lamp in structural design, shell and reflector are special requirements. More dust in the environment should be used lamps or closed has up to the light of the current lamps and lanterns (see chart); Damp environment should be paid attention to in the shell closure and reflector surface treatment; General indoor commonly used open wide type lamps and lanterns, adopts enamel surface reflector, alumina membrane surface layer is thick with silica film or aluminum reflector; Considering the production place of inevitable vibration, fixed light source appropriate USES the loose lamp holder, and so on. There are a variety of industrial and mining lights fixed way. General lights have suction a top, the embedded, hoisting (use of straight pipe or chain) and suck wall etc form. Will move a type according to local
