High bay light, also known as high bay light, is a high-efficiency indoor LED lamp, which can be widely used in industrial plants, production workshops, supermarkets, sports and entertainment venues and warehouses.

高棚灯是现代工业照明的重要组成部分。传统的高棚灯通常使用250W，400W，500W，1000W金属卤化物灯。金属卤化物灯发射360度，光损耗大的缺点造成了能源的巨大浪费。因此，开发新型高效、节能、长寿命、高显色指数、环保型LED工矿灯对国家工业照明节能具有重要意义。高湾照明与工业生产密切相关。LED工矿灯以定向发光、低功耗、驱动特性好、响应速度快、抗震性高、使用寿命长、绿色环保等优点逐渐进入人们的视野。LED光源灯具已成为世界上取代传统光源最具优势的新一代节能光源。因此，LED高棚灯将成为传统大型工业厂房照明领域照明节能改造的最佳选择，也是大势所趋。

In order to meet the visual needs of different production operations and the needs of high bay light installation conditions, the reflector of high bay light should be able to produce light distributions of various widths. The surface is painted and glazed to make it appear white, and reflectors 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 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 long-term and reliably in places with poor environmental conditions such as dust and humidity, high bay light has special requirements in terms of structural design, housing and reflector. Closed luminaires or convection luminaires with upward luminous flux should be used in dusty environments; attention should be paid to the airtightness of the enclosure and the surface treatment of reflectors in humid environments; open luminaires are commonly used indoors, using enamel surface reflectors and surface oxidation The aluminum reflector 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-loosening lamp holder, and so on.　

There are many ways to fix the high bay light. General lighting has the form of ceiling, embedded, hoisting (using straight pipe or chain) and suction wall. Movable local illuminators are equipped with corresponding hooks, handles, clamp feet, etc.; fixed local illuminators are generally firmly locked on the working machine with screws or fixing mechanisms.
