Abstract

A system provides light of selectable spectral characteristic (e.g. a selectable color combination of light), for luminous applications such a signage and indicator lights (10). An optical integrating cavity (11) combines energy of different wavelengths from different sources, typically different colored LEDs. The cavity has a diffusively reflective interior surface (29) and an aperture (17) for allowing emission of combined light. Control of the intensity of emission of the sources sets the amount of each wavelength of light in the combined output and thus determines a spectral characteristic of the light output through the aperture. A deflector (25) shaped like a number, character, letter, or other symbol, may be coupled to a similarly shaped aperture. By combining several such fixtures, it is possible to spell out words and phrases, with selectable color lighting. Disclosed fixture examples use an extruded body member with appropriately located reflective surfaces to form both the cavity and deflector.
