US 2014/0232253 A1 · LIGHT EMITTING DIODE DEVICE

Abstract

A light emitting diode device including a base, at least one light emitting diode, a bulb, and a patterned reflective layer is provided. The light emitting diode and the bulb are both disposed on the base. The bulb has a side-wall and a reflective surface, wherein the side-wall surrounds the light emitting diode and the reflective surface connected with the side-wall is located above and facing the light emitting diode. The patterned reflective layer is disposed on the reflective surface. The light emitting diode device has side-emitting effects that a user desired by the co-disposition of the patterned reflective layer and the reflective surface.
