摘要
LEDPN结温上升会引起LED光学、电学和热学性能的变化,甚至过高的结温还会导致封装材料(例如环氧树脂)、荧光粉物理性能变坏,LED发光衰变直至失效,因此分析LED结温、热阻构成,如何降低PN结温升,是应用LED的重要关键所在。
LED PN junction temperature increases will cause LED optical, electrical and thermal properties of the changes, or even excessive junction temperature can lead to packaging materials (such as epoxy resin) , phosphordeterioration of physical properties, LED luminescence decay until Failure , The analysis of LED junction temperature, a heat resistance, how to reduce the PN junction temperature rise, LED application is an important key.
