Patent ID: 8474992

Claim:
A lighting device comprising: a light emitting module including a plurality of electrically connected light emitting bars each having a plurality of semiconductor light emitting devices; a chassis for containing the light emitting module and having a discharge opening for discharging light from each semiconductor light emitting device to an outside; a reflection sheet arranged in the chassis to reflect the light of the plurality of semiconductor light emitting devices to a side of the discharge opening; and a brightness nonuniformity reduction unit, wherein each of the said lighting bars include: a band plate-shaped substrate; a wiring formed to extend in a longitudinal direction on one surface of the substrate; the plurality of semiconductor light emitting devices arranged in one row on the one surface of the substrate and electrically connected to the wiring; and first and second connectors formed in proximity to opposing shorter sides of the substrate on the one surface of the substrate and electrically connected to the wiring, each of the first and second connectors having a top side surface, bottom side surface and opposing side surfaces extending between said bottom and top side surfaces, wherein the semiconductor light emitting device is a light emitting diode emitting a white light that has a light component in a horizontal direction, wherein the light emitting module is formed in a bar shape by electrically connecting the first connector and the second connector so as to be aligned in a longitudinal direction of two light emitting bars adjacent to each other when the plurality of light emitting bars are arranged in a longitudinal direction, wherein the reflection sheet has at least a plurality of corresponding holes through which the plurality of semiconductor light emitting devices are inserted, and the reflection sheet is arranged on the one surface of the substrate of the light emitting module while the semiconductor light emitting devices are inserted into the corresponding holes, and wherein the brightness nonuniformity reduction unit includes an inclined surface portion, the inclined surface portion being arranged in proximity to a position of the first and second connectors of each light emitting bar, and the inclined surface portion covering said side surfaces of the first and second connectors so as to suppress a decrease in brightness around the first and second connectors by reflecting in a horizontal direction light emitted by the semiconductor light emitting device to the first and second connectors.
