  • Patent number: 9691945
    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.

  • Patent number: 8746937
    Abstract: A head lamp assembly including a housing; a plurality of head lamp cases installed in the housing, wherein each head lamp case comprises a light emitting diode (LED) light source, and a heat sink for dissipating heat generated from the LED light source; and a plurality of ventilating fans for circulating air in the plurality of head lamp cases and installed in the plurality of head lamp cases, respectively. Accordingly, the ventilating fans installed in the head lamp cases have opposite ventilating directions, and thus air is circulated in the head lamp cases by the ventilating fans to thus improve heat dissipation effects.
