  • Publication number: 20120281387
    Abstract: A structure of light-emitting diode includes a base, a circuit board, at least one light emission chip, a light-transmitting resin layer, and a light adjustment film. The base forms a cavity. The circuit board is mounted at a bottom of the cavity. The light emission chip is electrically connected to the circuit board. The light-transmitting resin layer is received in the cavity and bonded to the circuit board to encapsulate the light emission chip. The light adjustment film is separately provided and is set on a top of the light-transmitting resin layer and contains therein uniformly distributed powders of phosphor to allow the light-emitting diode to project uniform light.
