摘要： Light beams are outputted from optical devices and mixed together to obtain uniform white light free from color stains, thereby achieving a backlight unit improved in light mixing feature. In the backlight unit, a surface light source has a reflecting surface with a plurality of optical devices mounted thereon. An optical sheet is disposed in front of the surface light source. A reflecting layer is disposed between the surface light source and the optical sheet and has reflectivity varied by an incident angle of light beams from the optical devices. The backlight unit enables the light beams from the optical devices to be mixed together. The light beams outputted from the optical devices are effectively mixed together by a reflecting layer having reflectively varied by an incident angle of the light beams from the optical devices, thereby achieving uniform white light without color stains.

摘要： An LED backlight unit includes a light source; a board including a circuit pattern printed on an underside thereof, and having at least one mounting hole perforated therein where the light source is inserted; a metal chassis having an inside surface on which an underside of the light source is mounted, and receiving the board to be arranged in parallel to and with a gap from the metal chassis; and a reflector arranged on a top surface of the board to reflect light generated from the light source. The heat radiating path for transferring heat from the light source to the outside can be more simplified to enhance heat radiation efficiency thereby raising product reliability. The number of whole components can be reduced and the board with the light mounted thereon can be replaced with an inexpensive part thereby saving fabrication cost.
