Research and application on the relation of the lumens depreciation with temperature rise about COB LED
Abstract: The fourth generation of new light source LED light-emitting diodes (LEDs) since developed after years of development，With its high integration， high brightness， long life， full color， green energy-saving advantages to become the new century， the most the most promising high-quality light source to meet the requirements of energy development. High integration and high brightness， high power and high junction temperature. The restriction of the packaging technology， the LED light extraction efficiency can reach 20%， only a large amount of electrical energy into heat in the LED junction temperature is high， and seriously affect the service life of the luminous efficiency drops， the consistency and uniformity，Wavelength redshift. To control the LED junction temperature makes the reliable， effective heat dissipation LED a focus of research. The microchannel heat dissipation is most companies in recent years， the main research the LED heat dissipation and reduce the general control of the temperature rise droop. IWould of microchannel heat sink by the study on simpleWater cooling.
