  • Louver type LED luminaire using dye-sensitized solar cell
    Patent number: 9121558
    Abstract: An LED luminaire has a dye-sensitized solar cell for converting light emitted from a light source to electric energy and uses the converted electric energy. Since the dye-sensitized solar cell plays a role of a louver, the LED luminaire may reflect or shield light and convert wasted light into power. Further, since energy consumption and green-house gas generation decrease, it is possible to provide an environment-friendly LED luminaire. Moreover, if the power generated by the dye-sensitized solar cell is used for cooling the LED luminaire, it is possible to enhance heat dissipation efficiency of the LED luminaire.
    Type: Grant

  • Diffusion type LED apparatus utilizing dye-sensitized solar cells
    Patent number: 8987756
    Abstract: An LED luminaire has a dye-sensitized solar cell for converting light emitted from a light source to electric energy and uses the converted electric energy. Since the dye-sensitized solar cell plays a role of a diffusion plate, the LED luminaire may diffuse light and convert wasted light into power. Further, since energy consumption and green-house gas generation decrease, it is possible to provide an environment-friendly LED luminaire. Moreover, if the power generated by the dye-sensitized solar cell is used for cooling the LED luminaire, it is possible to enhance heat dissipation efficiency of the LED luminaire.
