%X The main problem of GaAs based AlGaInP series LED is the low light extraction efficiency and heat generation inside,which have serious impact on the LED' lifetime. In this paper,we introduce a kind of LED with new surface structure formed of surface texture and light anti-reflecting layers through the post-epitaxial processing. In this new structure,the inside light transmission route has been changed and the current spreading is enhanced,which makes much more light emit outside. With the same injected curr...
