With "Waterproof Cooling Fan" LED luminous efficiency and process quickly to improve, plus the global carbon reduction, environmental awareness, LED application market gradually branched out into interior lighting, high-profile prospects, and is considered to replace the traditional light source a new generation of light. LED light source for indoor lighting, with energy saving and environmental protection, long service life, resistance to vibration, low power consumption, small size, difficult attenuation for low temperature environments and high luminous efficiency a number of advantages, but "Waterproof Cooling Fan" problems are the impact of high-power LED and stepping into popularization of bottlenecks. In the global carbon reduction craze, led lighting industry has become one of the most promising green energy industry of the 21st century. Sun LED lamp cooling modules, LED ball lamp 9W break through the bottleneck, the use of forced cooling (cooling fans) make LED ball lamp reaches 15W. Sun LED lamp cooling module has three innovative design: two-way operation of the automatic dust removal fan design, "Waterproof Cooling Fan" to prevent hot air patent barrier ring design, as well as meet the high quality quiet cooling design. Through research and psycho-acoustic sound quality parameters to simulate the feelings of human hearing, people almost feel less cooling fan rotation.
