(Summary description)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 new LED lamps, there are obvious differences:
2 Light source selection
At present, the well-known brands of high-power LED industrial and mining light sources on the market are: CREE, OSRAM, NICHIA, Lumileds, and Taiwanese manufacturers Epistar, Addison, and domestic packaging manufacturers Shenzhen Wanrun, Guangzhou Hongli, Shenzhen Hongya And so on are also popular brands.
3 Heat dissipation design:
　 In the use of high-power LEDs, heat dissipation is a big problem. For example, if a 10W white light 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 ( When TJ) rises above the allowable temperature (usually 150°C), high-power LEDs will be damaged due to overheating. Therefore, heat dissipation design is also an important content for us. In the following, we will discuss the heat dissipation design from the combination of aluminum substrate and heat sink.
4 Mechanism 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 die-casting radiator from the following four aspects.
5. LED high bay light verification results
　 In order to ensure the quality of the lamps, we have carried out a series of tests on light distribution, thermal, and reliability before mass production and shipment. The following are the verification results of each test.
6. 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 obviously much higher than that of traditional lamps. However, because the LED light source has the characteristics of high luminous efficiency, and when the lamp is made, the advantage of the strong directivity of the LED light source is easily reflected. The efficiency of the LED lamp is much higher than that of the traditional lamp, so its energy-saving characteristics can be Clearly manifested.
