摘要
An illumination module emits light from at least one light emitting diode (LED) with a peak wavelength between 380 nanometers and 460 nanometers that is converted to a second colored light by interaction with at least four different photo-luminescent materials in a light conversion sub-assembly. A first photo-luminescent material has a peak emission at a wavelength that is within 55 nanometers of the peak wavelength of the light emitted from the LED. A second photo-luminescent material has a peak emission at a wavelength greater than 650 nanometers. A third photo-luminescent material has a peak emission at a wavelength that is more than 20 nanometers greater than the peak emission wavelength of the first photo-luminescent material. A fourth photo-luminescent material has a peak emission at a wavelength that is at least 20 nanometers less than the second photo-luminescent material.
