Abstract:
1. A multi-light emitting diode (LED) package, comprising: an integrally formed heat sink comprising an upper surface and a cavity on the upper surface; a primary LED chip arranged on a bottom surface of the cavity; a secondary LED chip arranged on the heat sink upper surface outside the cavity, the secondary LED chip being one of a red LED chip, a green LED chip, a blue LED chip, an infrared LED chip, and an ultraviolet LED chip; a lead frame structure electrically connected to the primary LED chip and the secondary LED chip, the lead frame structure to individually operate the primary LED chip and the secondary LED chip; and a phosphor mixed with a transparent resin, the phosphor and the transparent resin being arranged in the cavity to cover at least a part of the primary LED chip; wherein the secondary LED chip is not covered by any phosphor, wherein the multi-LED package is configured to emit a white light using the phosphor and the primary LED chip, a non-white light using the secondary LED chip, or both the white light and the non-white light, wherein the primary LED chip is arranged on the bottom surface of the cavity, the bottom surface of the cavity being coplanar with an upper surface of the heat sink, and wherein the bottom surface of the cavity is separated from the upper surface of the heat sink by a raised partition protruding from the heat sink, wherein the raised partition comprises a coplanar upper surface that completely surrounds the primary LED chip and separates the primary LED chip from the secondary LED chip.
