The existence of high-power industrial and mining lamps is of great significance, and it has a very large family. LED floodlights, LED street lights, LED lamps, LED flood lights, etc., each partner is wearing beautiful and gorgeous clothes to compete for favor with people.
High-power high bay lights often shuttle in the workshops of high bay light manufacturers, shipyards, workshops, warehouses, mines, highway toll stations, gas stations, large supermarkets, exhibition halls, gymnasiums and other places. It can realize its own value here, and has the characteristics of high efficiency and energy saving. With it installed, you can save 60% on your electricity bill compared to your current light. If you now pay 10,000 yuan a month for electricity bills, it is enough to pay only 4,000 yuan in my words. Not all high-power high bay lights have a lifespan of 50,000 hours, not all high-power high-bay lights are tailor-made for you, not all high-power high-bay lights are radiation-free, UV-free, not all high-power high-bay lights Both have high power conversion efficiency and good stability.
High power industrial and mining lamps
At present, the total heat dissipation efficiency of high-power industrial and mining lamps is only 50%, and there is still a lot of electric energy to be converted into heat energy. Secondly, high-power high bay lights will generate more concentrated waste heat, which needs to be well dissipated. In order to improve the cooling level, we offer the following suggestions:
1) From the perspective of LED chips, it is necessary to adopt new structures and new processes to improve the heat resistance of the junction temperature of the LED chips and the heat resistance of other materials, so that the requirements for heat dissipation conditions are reduced.
2) Reduce the thermal resistance of LED devices, adopt new packaging structure and new process, and select new materials with better thermal conductivity and heat resistance, including bonding materials between metals, etc., so that the thermal resistance is ≤10℃/W or lower .
3) Reduce the temperature rise, try to use heat dissipation materials with good thermal conductivity, and require better ventilation channels in the design, so that the waste heat can be dissipated as soon as possible, and the temperature rise should be less than 30 °C.
4) There are many ways to dissipate heat, such as the use of heat pipes, which is of course very good, but the cost factor should be considered, and the cost-effectiveness should be considered in the design.
