  • Illumination module
    Patent number: 8740438
    Abstract: An illuminating module includes at least one light-emitting chip, a phosphor, and a color temperature conversion media. The light-emitting chip is capable of emitting wavelength light, and the phosphor is disposed in a propagation path of the wavelength light to transform the wavelength light into a first white light with a first color temperature. The color temperature conversion media is disposed in a propagation path of the first white light to transform the first white light into a second white light with a second color temperature. The second color temperature is smaller than the first color temperature.
    Type: Grant
