Abstract: A lighting apparatus includes first and second light emitting areas, a color temperature controller, and a balance circuit. The first light emitting area includes first light-emitting arrays connected in series and outputs light of a first color temperature. The second light emitting area includes second light-emitting arrays connected in series and connected to the first light emitting area in parallel. The second light-emitting arrays output light of a second color temperature different from the first color temperature. The color temperature controller is selectively connected to at least one of an input node of the first light emitting area and an input node of the second light emitting area. The color temperature controllers determines an on/off state of the first and second light emitting areas. The balance circuit is connected to at least one of the first and second light emitting areas in series.

Abstract: A light emitting device is provide comprising a light emitting diode (LED) chip having a first main surface and a second main surface opposing the first main surface, and one or more side surfaces extending between the first main surface and second main surface. A plurality of electrodes is disposed on the first main surface. A wavelength conversion film is disposed on the second main surface. A mark is formed in the wavelength conversion film. The mark contains orientation information of the light emitting device, thereby enabling the light emitting device to be properly oriented on a receiving substrate.
