Patent ID: 7530709

Claim:
An illumination apparatus having a light-transmitting frame, comprising: a substrate; a first light emitting diode and a second light emitting diode mounted on the substrate and configured to emit different colored lights, respectively; and a single light-transmitting frame comprising a side wall and an upper wall which form a concave portion, mounted on the substrate and configured to cover the first and the second light emitting diodes from above within the concave portion; wherein the upper wall of the light-transmitting frame includes an inside surface comprising a first light incident area and a second light incident area, each of the first and second light incident areas faces each one of the first and the second light emitting diodes, and an outside surface comprising a first light exit area configured to face the first light incident area and a second light exit area configured to surround the first light exit area, respectively, and further; wherein the inside surface of the upper wall of the light-transmitting frame has a stepped portion separating the first and the second light incident areas, the first light incident area is separated by the stepped portion to receive light emitted from the first light emitting diode and to pass the light through the upper wall of the light-transmitting frame at the first light exit area; wherein the second light incident area is separated by the stepped portion to receive light emitted from the second light emitting diode and to pass the light through the upper wall of the light-transmitting frame at the second light exit area, which is configured to surround the first light exit area.
