Abstract:
1. A method comprising: measuring a first color point of a light emitting diode (LED) based illumination module in a visually matched color space, wherein a visually matched color space is a space in which light emitted from an LED based illumination module at a target color point visually matches a target light that is not based on solid state technology at the same target color point; comparing the measured first color point to the target color point of the target light in the visually matched color space, wherein the target light is not generated by a LED; and selecting and installing in the LED based illumination module a first selectable component that includes a first type of wavelength converting material having a first wavelength converting characteristic that converts light produced by at least one light emitting diode of the LED based illumination module to shift the first color point in the visually matched color space to within a predetermined tolerance of the target color point, wherein a light emitted from the LED based illumination module at the target color point visually matches the target light at the target color point.
