In order to meet the visual needs of different production operations and the requirements of lighting installation conditions, the reflector of industrial and mining lamps should be able to produce various widths of light distribution. The surface is painted and glazed to make it appear white, and the reflector made of aluminum, glass mirror, prism glass and other materials can get a wide light distribution, suitable for a large area, the work surface is vertical or near vertical workplace . For tall buildings and places with tall machine tools that require separate lighting, reflectors made of materials with strong light control properties, such as prism glass, mirror glass, and polished aluminum, can be used to obtain a narrow beam distribution.
In order to work reliably for a long period of time in places with poor environmental conditions such as dust and humidity, industrial and mining lamps have special requirements in terms of structural design, housing and reflector. In a dusty environment, closed lamps or convection lamps with upward light flux should be used (see figure); in a humid environment, attention should be paid to the tightness of the enclosure and the surface treatment of the reflector; open lamps used in general indoors are usually used, and the enamel surface is used for reflection Aluminium reflectors with thick aluminum oxide coatings or coated with silicon dioxide protective film; taking into account the inevitable vibration in the production site, fixed light sources should use anti-loosening lamp holders, etc. Industrial and mining lamps have a variety of fixing methods. The general lighting has the forms of ceiling, embedding, hoisting (using straight pipe or chain) and suction wall. Removable local illumination lamps are equipped with corresponding hooks, handles, clamping feet, etc.; fixed local illumination lamps are generally firmly locked on the working machine with screws or fixing mechanisms.
