  • Patent number: 8870617
    Abstract: Multiple colors of light emitted by an assembled light emitting diode (LED) based illumination device is automatically tuned to within a predefined tolerance of multiple target color points by modifying portions of wavelength converting materials associated with each color. A first color of light emitted from the assembled LED based illumination device in response to a first current is measured and a second color of light emitted from the assembled LED based illumination device in response to a second current is measured. A material modification plan to modify wavelength converting materials is determined based at least in part on the measured colors of light and desired colors of light to be emitted. The wavelength converting materials may be selectively modified in accordance with the material modification plan so that the assembled LED based illumination device emits colors of light that are within a predetermined tolerance of target color points.

  • Patent number: 8841831
    Abstract: A light emitting device includes a first luminous body having a first light source and a long wavelength cut-off filter; and a second luminous body generating light of different color from that of the first luminous body, and having a second light source and a short wavelength cut-off filter. The first and the second light source emit light in a first wavelength range and a second wavelength range extending to a longer wavelength side than the first wavelength range while overlapping with the first wavelength range, respectively. The long and the short wavelength cut-off filter cut off light having a wavelength longer than a first set wavelength and shorter longer than a second set wavelength, respectively. Thus, light emitted from the first luminous body and light emitted from the second luminous body are mixed together, such that light in between the first set wavelength and the second set wavelength is reduced.
