Energy-saving industrial and mining lamps can be divided into general lighting and partial lighting according to their bright functions: general lighting is usually symmetrically arranged on the upper side or outer wall of the working environment to illuminate all work surfaces, and fluorescent lamps and halogen tungsten lamps with excessive output power must be used. , high toughness metal halide lamps or a large number of fluorescent tubes.
Most of the environmental protection and energy-saving high bay lamps belong to this category. Generally, lighting lamps have higher requirements on the distribution of light sources, and two types of light distribution, immediate lighting type and semi-direct lighting type, are generally used, especially the latter. In the semi-immediate lighting type, a part of the upward light source illuminates the canopy, which can enhance the canopy chromaticity and create a more comfortable and brighter natural environment. The 4th generation light source used in LED high bay light has the following advantages over other light sources, such as fluorescent lamps, metal halide lamps, high pressure sodium lamps, and led floodlights: Working voltage: LED high bay light source applies low voltage switching power supply, single bead working voltage In the middle of 1.9-4V, it is a more reliable switching power supply than applying DC high voltage power supply.
High-power high bay lamp efficiency: high luminous efficiency, the maximum luminous efficiency of the laboratory has reached 161lm/w (cree) at this stage, and it is a lighting commodity with high luminous efficiency at this stage. Theoretically, the high fluorescent efficiency per watt of LEDs can reach 370LM/W. At this stage, the integrated IC structure does not have to be changed. The better processing technology allows the LEDs to reach 150LM per watt without problems. When this kind of chromaticity is achieved , most of the lighting industry can be replaced. It is estimated that in the next 1 to 3 years, the LED light source will achieve a high light efficiency of 300 lumens per watt. At this stage, the LEDs in the UK laboratory have achieved a high light efficiency of 161 lumens per watt, and the total lumen value is 175LM. Shock resistance: LED is a solid light source, because of its uniqueness, it has shock resistance unmatched by other light source products. Reliability: 100,000 hours, light loss is 70% of the original.
