Subject: Automotive LED-reduce the junction temperature.
2010-03-01



LED proportion of each part of heat flux, of which aluminum plate (MCPCB) and the electrode pins (Lead) the largest percentage share of heat flux, due to LED junction temperature is much lower temperatures than other light sources, it is unable to heat and light radiation mode with Injection to go, so LED as much as about 90% of the waste heat to heat conduction outward proliferation, under the action of a high current intensity, LED chip junction temperature increases, the need for a good LED package and module design, to provide adequate heat transfer LED ways to reduce the junction temperature.
