    摘要: A color sensor for measuring light from a light source and the method for fabricating the color sensor. The color sensor includes a plurality of photodetectors, a plurality of primary color filters and a trim filter. Each primary color filter includes a layer of material between the light source and a corresponding one of the photodetectors. Each primary color filter preferentially transmits light in a corresponding band of wavelengths about a characteristic wavelength. The trim filter is located between the light source and the photodetectors and includes a layer of material that preferentially attenuates light at a first trim wavelength between two of the characteristic wavelengths. In one embodiment, the trim filter further preferentially attenuates light at a second trim wavelength, the first wavelength being less than one of the characteristic wavelengths and the second wavelength being greater than that characteristic wavelength.

    摘要: A light source having first and second component light sources, a mixing device, and a controller is disclosed. The first component light source generates light having a perceived color that can be varied within a predetermined two-dimensional region of the CIE 1976 color space in response to a set of color control signals. The second component light source generates white light. The mixing device combines light from the first and second component light sources to produce an output light signal having a perceived output color. The controller generates the set of color control signals in response to an input signal from a source external to the light source, the controller maintaining the perceived output color at a point in the CIE 1976 color space determined by the input signal.
