LUMINAIRE WITH A REFLECTOR AND LEDS |
摘要 |
A light source includes an array of LED components in each of a plurality of colors such as red, green, and blue in the entrance aperture of a tubular reflector which has an exit aperture, an optic axis extending between the apertures, and a reflective circumferential wall extending between the apertures to reflect and mix light from the array of LED components. At least a portion of the circumferential wall of the reflector body has a polygonal cross-section taken normal to the optic axis, and at least a portion of the cross-section taken parallel to the optic axis includes segments of a curve joined one to the next to form a plurality of facets for reflecting light from the LED components to said exit aperture. Preferably, the segments of the curve included in the cross-section of the reflector body taken parallel to the optic axis are contiguous, linear trapezoidal facets. |
