Open publisher page 1 citations

Abstract

InGaAlP LED has the featares of high luminous efficiency, stable property and wide application. Luminous characteristic is a very important parameter in the InGaAlP LED application which consists of two main parameters-luminous intensity and half-intensity angle. This article introduced different chip structures of InGaAlP LED, analyzed its lighting property and luminous characteristic after packaging. It also discussed the effect of different reflective lead frame structure on the luminous characteristic, which has good significance for the InGaAlP LED production and its application.
