1. History The invention of epoxy resin has undergone a long period of time. As early as 1891‚ the German Lindmann hydroquinone and epichlorohydrin with the reaction of condensation into the resin and make use of anhydride curing. But its value has not been revealed. Epoxy plastic has its roots far back in history‚ to be specific‚ in 1936‚ when Dr. Pierre Castan in Switzerland succeeded in synthesizing an epoxy resin that he hardened with pthalic acid anhydride. Dr. Castan’s work was licensed

eliminating the need to utilize a mold. Current injection into a bare LED chip‚ triggers a photosensitive epoxy to polymerize‚ leading to the formation of mushroom lamp cap on the LED chip. The emission properties of LEDs fabricated by this method‚ including their emission beam profiles and light outputs‚ were characterized. The results showed that a self-focusing effect happened with the addition of an epoxy on the chip. The simulation demonstrated that the geometry the encapsulant controlled the beam pattern
