1. A high power light emitting diode package comprising:
- an insulation main body having an opening to a bottom surface;
at least two lead terminals fixed to the main body; and
at least two heat sinks of electrically and thermally conductive metallic materials, the heat sinks being separated from each other and the at least two lead terminals, and fixed to the main body, wherein a lower portion of each of the at least two heat sinks is exposed to the outside of the bottom surface of the main body through the opening of the main body.

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.

16. A high power light emitting diode package comprising:
-
an insulation main body; at least two lead terminals fixed to the main body; at least two heat sinks of electrically and thermally conductive materials, the heat sinks being separated from each other and fixed to the main body, each of the at least two heat sinks having an upper surface and a lower surface, the lower surface of each of the at least two heat sinks being relatively wider than the upper surface of each of the at least two heat sinks; and a light emitting diode die mounted on one of the upper surfaces of the heat sinks, the light emitting diode die having a lower surface facing the upper surface of each of the at least two heat sinks, wherein the upper surface of each of the at least two heat sinks is wider than the lower surface of the light emitting diode die, so that the light emitting diode die mounted partly on a portion of the heat sink. - View Dependent Claims (18)
