The beautiful led lights effect can not afford the high cost of injury

The beautiful led lights effect can not afford the high cost of injury
Advances in technology, skills enhancement, car manufacturing has brought more changes. In recent years, the popular group of the led lights  give us a shine. With widely used "daytime running lights", both beautiful "angel eyes" began to appear in the streets. When people enjoy these cool equipment that brings the visual pleasure at the same time, the problem behind also call for deep thought. Recently, the "Southern Metropolis Daily" damage replacement the led lights produced by the high cost ...Continue reading

Introductions of LED testing methods (3)

Introductions of LED testing methods (3)
Thermal property of LED refers to thermal resistance and PN junction temperature. Thermal resistance is the ratio of temperature difference in channel to its power consumption. Resistance and junction temperature are two important parameters which will impact an influence on LED High Bay photoelectric properties. There are two main methods for measuring LED junction temperature: using infrared microscope and micro-thermocouple to measure the surface temperature of LED chips. This value is approx...Continue reading

high power led price continued to fall 20%, half of domestic fear factory will close down

high power led price continued to fall 20%, half of domestic fear factory will close down
Overcapacity, high power led price are falling down, probably make half of production used in Sam sung Electronics (Sam sung) LCD TV, Sharp, computer display back-light light-emitting diode (LED High Bay) industry closed down. The only survival industry is the one who gets countries to foster. HSBC (HSBC) Jerry Tsai analyst pointed out that, the global television, computer sales weakness in fear so that LED Street Light prices continued to fall 20% in 2012. For smaller domestic LED industry, fac...Continue reading

heat sink design of top led lighting companies
LED applications is now becoming more diversified, due to the high-power LED input power of only 15 to 20% into light, and the remaining 80-85% is converted into heat, if heat is not timely discharged to the outside world, then will make the LED High Bay chip interface temperature is too high to affect the luminescence efficiency and luminescence lifetime from the top led lighting companies. As the LED materials and packaging technologies continue to develop, to promote the brightness of the LED...Continue reading
