Light emission device and method utilizing multiple emitters
Abstract:
A light emission device includes multiple electrically activated solid state emitters (e.g., LEDs) having differing spectral output from one another; and/or phosphor material including one or more phosphors arranged to receive spectral output from at least one of the solid state emitters and to responsively emit a phosphor output, to provide spectral output. In one arrangement, at least four electrically activated solid state emitters each have different spectral outputs in the visible range, with the emitters arranged in an array positioned on a single reflector cup or other support, with at least two solid state emitters differing substantially in size. Aggregated output may include white light having a color temperature in any of several desired ranges.
