ABSTRACT:
The present invention comprises a method and apparatus for providing user selectable multi-color illumination to automotive instrument panel instruments. In one embodiment, an instrument panel or individual instrument is supplied with a plurality of differently colored illumination sources. The intensity of each color is individually controllable, allowing the user to select both intensity and hue of instrument illumination. In one embodiment, an instrument panel illumination system comprises three light sources that produce nominally white light and three associated diffusing filters, one red, one green, one blue. In another embodiment different colors of illumination are provided by light sources producing different colors of light, such as, for example, a plurality of high intensity red, green, and blue light emitting diodes ("LED's"). In one embodiment, a plurality of triplets of red, green and blue high intensity LED's are mounted above a white diffusing filter. In one embodiment, a plurality of colored light sources are mounted in an instrument housing behind the instrument's bezel.
