  • Film-covered LED device
    Patent number: 8476650
    Abstract: A film-covered LED device includes a high thermal conductive substrate, a reflector, a plurality of LED chips, and a fluorescent film. A pair of electrical contacts is respectively disposed on two ends of the high thermal conductive substrate. A thru opening is formed on the reflector, which is disposed on the high thermal conductive substrate. The LED chips are disposed on the high thermal conductive substrate and connected electrically, within the thru opening. The fluorescent film is disposed on the reflector and casted over the LED chips. Thereby, the LEDs illumination is more evenly distributed, in maintaining illumination efficiency uniformity. The yield rate is also enhanced with savings in labor cost.
