In order to meet the visual needs of different production operations and the requirements of the installation conditions of the lamps, the reflector of the mining lamp should be able to produce various broad and narrow light distributions. The surface is painted, glazed to make it white, and the reflector made of aluminum, glass mirror, prism glass and other materials can obtain a wide light distribution, suitable for large area, working surface vertical or near vertical working place. . For high-rise buildings and high-altitude machine tools that require separate illumination, reflectors made of materials such as prismatic glass, mirror glass, and polished aluminum can be used to obtain a narrow beam distribution. In order to work long-term and reliable in places with poor environmental conditions such as dust and humidity, industrial and mining lamps have special requirements in structural design, casing and reflector. In a dusty environment, use closed lamps or convection lamps with upward illumination; in a humid environment, pay attention to the tightness of the casing and the surface treatment of the reflector; generally open indoor lamps, enamel reflectors, surface oxidation Aluminium reflectors with a thick aluminum film or coated with a silicon dioxide protective film; in view of the inevitable vibration in the production site, a fixed light source should be a lock-proof lamp holder, and the like. There are various ways to fix the mining lamps. General lighting has the form of ceiling, embedding, lifting (using straight pipe or chain) and suction wall. The movable partial illumination lamp is equipped with corresponding hooks, handles, pinches, etc.; the fixed partial illumination lamps are generally firmly locked on the working machine by screws or fixing mechanisms.
