  • Street lamp emitting filtered light
    Patent number: 7963668
    Abstract: A street lamp includes a lampshade, a light-emitting diode array, a lens array, and a filter film. The lampshade includes a bottom wall and a sidewall extending around the bottom wall, the lampshade defines a receiving space with an opening opposite to the bottom wall. The light-emitting diode array is received in the receiving space and has a number of light-emitting diodes which light emitting direction faces to the opening of the lampshade. The lens array has a number of lenses corresponding to the light-emitting diodes, the lenses is capable of converging light emitting from the light-emitting diodes. The filter film is disposed on the optical path of the plurality of light-emitting diodes for filtering light of predetermined wavelength ranges.
