Cooling Kit truly first brand! ! ! ] Where the LED plastic heat has been a serious problem research data show that if the light-emitting LED chip junction temperature of 25 degrees is 100%, then when the junction temperature rises to 60 degrees, the luminous amount to only 90%!; 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 LED bulb purchase, cooling LED LED lighting design is the most important issue.

Cooling Kit truly first brand! ! ! ] With our thermally conductive plastic casing can save much power, with economic development, people's living standards continue to improve LED bulb, energy saving and environmental protection this topic more and more attention. At present, many projects achieved great success in environmental protection and energy saving. For example, this one in energy-saving, LED lighting will play a very big role. Experts predict that by 2020, global LED market share will reach 80%. So how energy-efficient LED lamps in the end quality LED bulb, take Pu Yi million LED bulbs for lighting, a 5-watt LED bulb equivalent to 15-watt light shines ordinary energy-saving lamp life up to 50,000 hours, the basic free Maintenance. LED bulb manufacturers, Pu Yi million - Technology (online consultation), Zhangmutou LED bulb provided by the Dongguan City, Pu Yi million Optoelectronics Technology Co., Ltd. heat. Dongguan City, Pu Yi million Optical Cooling Technology Co., Ltd. (www.powide.com) is Dongguan, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In general Wan cooling technology leaders with the staff warmly welcome all inquiries negotiations to create a general cooling of Science and Technology Wan better future.
