Abstract:
1. An encapsulation structure for encapsulating an LED chip, comprising: a first encapsulation defining a receiving room for receiving the LED chip therein; a second encapsulation defining a receiving space receiving the first encapsulation therein, the second encapsulation spaced from the first encapsulation to define a clearance therebetween; and a transparent resin layer with phosphorous compounds doped therein being filled in the clearance, the transparent resin layer having a uniform thickness; wherein the first encapsulation comprises an annular first mounting surface, a first light exit surface connected to an outer periphery of the first mounting surface and a first light incident surface connected to an inner periphery of the first mounting surface, the first light incident surface concaved from the inner periphery of the first mounting surface towards the first light exit surface to define the receiving room enclosed by the first light incident surface; and wherein the second encapsulation comprises an annular second mounting surface, a second light exit surface connected to an outer periphery of the second mounting surface and a second light incident surface connected to an inner periphery of the second mounting surface, the second light incident surface concaved from the inner periphery of the second mounting surface towards the second light exit surface to define the receiving space enclosed by the second light incident surface, the first mounting surface and the second mounting surface being coplanar to each other.
