发明名称 Light emission device and method utilizing multiple emitters and multiple phosphors
摘要 A light emission device, including at least two LED dies having differing spectral output from one another; and phosphor material including one or more phosphors, arranged to receive spectral output from at least one of the LED dies and to responsively emit a phosphor output, as a component of a spectral output of the light emission device. In a specific arrangement, the multiple LED dies and phosphor material are arranged to produce a white light output having a color temperature selected from among (i) color temperature in a range of from 1350° K to 1550° K, (ii) color temperature in a range of from 2400° K to 3550° K and (iii) color temperature in a range of from 4950° K to 6050° K.
