In addition to energy saving and environmental protection, the lighting fixtures using the new light source LED high bay lamps also have the advantage of pure light concentration. New technologies, new materials and new processes have been continuously applied to the design of high-power LED high bay lights, laying a solid foundation for the design of high-power LED high bay lights. The design of LED high bay lights involves more details. High bay light manufacturers believe that we follow the following important considerations to reflect the design process and methods:
1 power selection
Traditional high bay lamps are mostly 250W or 400W high pressure sodium lamps and metal halide lamps. Compared with the characteristics of the new LED lamps, there are obvious differences:
2Light source selection
There are many well-known brands of high-power LED industrial and mining light sources on the market.
3 Heat dissipation design:
In the use of high-power LEDs, heat dissipation is a big problem. For example, if a 10W white LED has a photoelectric conversion efficiency of 20%, 8W of electrical energy is converted into heat. If no heat dissipation measures are taken, the core temperature of the high-power LED will rise rapidly, when its junction temperature (TJ) When the temperature rises above the maximum allowable temperature (usually 150°C), the high-power LED will be damaged due to overheating. Therefore, heat dissipation design is also our most important content. In the following, we will discuss heat dissipation design from the combination of aluminum substrate and heat sink.
4 Institutional design
The design of LED high bay light mechanism involves not only the mechanical structure of the whole lamp, but also the beautiful appearance of the lamp. Next, we carry out the specific design of the die-casting radiator from the following four aspects.
5. Cost and benefit evaluation
Compared with high-pressure sodium lamps or metal halide lamps for plant lighting, the initial investment cost of LED high bay lamps is significantly higher than that of traditional lamps. However, since the LED light source has the characteristics of high luminous efficiency, and when it is made into a lamp, it is easy to reflect the advantage of the strong directivity of the LED light source. The efficiency of LED lights is much higher than that of traditional lights, so its energy-saving characteristics can be clearly reflected.
