LIGHTING DEVICE INCLUDING ONE OR MORE SATURATED AND NON - SATURATED LIGHT EMITTERS, AND METHOD OF COMBINING LIGHT FROM THE EMITTERS

摘要

A solid state lighting device comprising at least one first light emitter (121) that emits non- saturated non- white light of a first color point, at least one second light emitter (122) that emits saturated non- white light, and a controller (1,2,3) configured to control a ratio of light emitted by the first emitter (s) (121) and by the second light emitter (s) (122) to provide non- white light of a second color point. Also, a solid state lighting device comprising at least one first light emitter (121) that emits light within a first area or a second area on a Chromaticity Diagram, and at least one second light emitter (122), wherein output light is non-white and has a second color point. Also, methods of providing non- white light.
