In order  meet the visual needs of different production operations and the needs of lighting installation conditions, the reflecr of the industrial and mining lamp should be able  produce various wide and narrow light distributions. The surface is painted and glazed  make it appear white, and reflecrs made of aluminum, glass mirrors, prism glass and other materials can obtain a wide light distribution, which is suitable for large-area, vertical or nearly vertical workplaces . For tall workshops and places with tall machine ols that require separate lighting, reflecrs made of materials with strong light control properties such as prism glass, mirror glass, and polished aluminum can be used  obtain a narrow beam distribution.

　　In order  work long-term and reliably in places with poor environmental conditions such as dust and humidity, high bay lights have special requirements in terms of structural design, housing, and reflecrs. Closed luminaires or convection luminaires with upward luminous flux should be used in dusty environments; attention should be paid  the airtightness of the enclosure and the surface treatment of reflecrs in humid environments; open luminaires are commonly used indoors, using enamel surface reflecrs and surface oxidation The aluminum reflecr with thick aluminum film or coated with silicon dioxide protective film; considering the inevitable vibration in the production site, the fixed light source should adopt the anti-loosing lamp holder, and so on. There are many ways  fix high bay lights. General lighting has the form of ceiling, embedded, hoisting (using straight pipe or chain) and suction wall. Movable local illuminars are equipped with corresponding hooks, handles, clamp feet, etc.; fixed local illuminars are generally firmly locked on the working machine with screws or fixing mechanisms.
