1. A light-emitting diode (LED) package, comprising:
- a one-piece main body comprising an opening in a bottom surface thereof;
a first heat sink, a second heat sink, and a third heat sink each comprising a thermally conductive material; and
a first light emitting diode die arranged on an upper surface of the first heat sink and a second light emitting diode arranged on an upper surface of the second heat sink; and
a zener diode arranged on an upper surface of the third heat sink,wherein the first heat sink, the second heat sink, and the third heat sink are spaced apart from each other,wherein a lower surface of each of the first heat sink, the second heat sink, and the third heat sink is exposed to air by the opening,wherein the upper surfaces and the lower surfaces are opposite to each other,wherein the first heat sink the second heat sink, and the third heat sink each comprise a reflective surface integrally formed with and extended from the upper surface thereof,wherein the lower surface of each of the first heat sink, the second heat sink, and the third heat sink exposed by the opening is wider than the upper surface of each of the first heat sink, the second heat sink, and the third heat sink.

Abstract
There is provided a light emitting diode package having at least two heat sinks. The light emitting diode package includes a main body, at least two lead terminals fixed to the main body, and at least two heat sinks of electrically and thermally conductive materials, the heat sinks being fixed to the main body. The at least two heat sinks are separated from each other. Thus, high luminous power can be obtained mounting a plurality of light emitting diode dies in one LED package. Further, it is possible to embody polychromatic lights mounting LED dies emitting different wavelengths of light each other in the LED package.
