Cooling Kit truly first brand! ! ! ] Where the LED plastic heat has been a serious problem! There data indicate LED bulb brand, if the LED chip junction temperature of 25 degrees is 100% LED luminous bulb fittings, so the junction temperature rises to 60 degrees When the luminous amount is only 90%; a junction temperature of 100 degrees, drops to 80 percent; only 70 percent of 140 degrees. Visible improve heat dissipation, junction temperature control is very important. In addition to LED's heat also makes its spectral shift; color temperature increases; forward current increases (at constant power); reverse current increases; increased thermal stress; phosphor epoxy accelerated aging, etc. all sorts of problems, so that the heat LED LED lighting design is the most important issue. [Pu Wan heat Technology - industry, academia, research, sales for the body, is committed to building a low-carbon environmental protection high-tech entrepreneurs in China Green Smart LED bulb, high heat, high insulation, low-density, high-performance | similar products Enterprise benchmarking enterprise! Cooling Kit truly first brand! ! ! ] LED lamp technology degree carried out quickly, but most LED bulb lamp manufacturers in the product development process neglect the special technical requirements applied in cold environments. A common misconception is: LED application in the cold area is conducive to heat, not easy to attack problems. As everyone knows, under ice environments, LED lights have a more stringent technical requirements, mainly in the following two aspects: first, the cold area temperature is low, and the temperature, thermal shock and sudden changes in the long-term work on low temperature devices It has more stringent quality requirements. Second, the application of LED lights ice area will need to think about preventive measures to avoid ice condensation.
