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.
