  • Illumination device with at least one LED as the light source
    Patent number: 7821196
    Abstract: An illumination device with at least one LED as the light source, the LED emitting primary radiation in the range from 370 to 430 nm of the optical spectral region (peak wavelength), this radiation being partially or completely converted into radiation of a longer wavelength by three phosphors which are exposed to the primary radiation from the LED and which emit in the blue, green and red spectral regions, so that white light is formed. The conversion is achieved at least with the aid of a phosphor which emits blue light with a wavelength maximum at 440 to 485 nm, and with the aid of a phosphor which emits green light with a wavelength maximum at 505 to 550 nm, and with the aid of a phosphor which emits red light with a wavelength maximum at 560 to 670 nm.

  • Illumination device with at least one LED as the light source
    Patent number: 7239082
    Abstract: The invention relates to a luminescence conversion led based illumination deice that emits primarily radiation in the range of from 370 and 430 nm of the optical spectrum (peak wavelength). Said radiation is converted to radiation having a longer wavelength using three luminescent substances that emit in the red, green and blue range.
