Abstract

A light emitting diode of the present invention comprises a support frame, a shell, a light emitting diode chip and an encapsulating body. The shell is used to accommodate the support frame. The shell has a bowl-shaped structure and the bowl-shaped structure has two opposite first walls and two opposite second walls. The upper edge of the second wall is a concave-convex structure. The encapsulating body is used to package the bowl-shaped structure and the encapsulating body has a concave-convex structure similar to the concave-convex structure of the bowl-shaped structure. The concave-convex structure comprises a concave portion and a convex portion. The structure of the light emitting diode is simplified. The luminous intensity and the light extraction efficiency of the light emitting diode are enhanced and the thickness of the light emitting diode is not increased.
