Light-emitting diode

The invention discloses a light-emitting diode which comprises a bracket, a shell, a light-emitting diode chip and an encapsulation colloid, wherein the shell is used for containing the bracket and has a bowl-shaped structure; the bowl-shaped structure has first bowl walls and second bowl walls which are two-two opposite, wherein the upper edges of the second bowl walls are of concave-convex structures; the encapsulation colloid is used for encapsulating the bowl structure and has a concave-convex structure which is accordant with the concave-convex structure of the bowl-shaped structure; and the concave-convex structure comprises a convex structure and a concave structure. The light-emitting diode has simple structure, not only promotes the light-emitting strength and the light-emitting efficiency of the light-emitting diode, but also does not increase the thickness of the light-emitting diode and also does not exist the problems of gel convexity and material blocking.
