ABSTRACT:
A lighting device, comprising a solid state light emitter and a light filter. At least a portion of light emitted by the light emitter contacts the filter, and at least part of the light passes through the filter. Also, such lighting devices further comprising lumiphor, in which at least some of the first part of the light is absorbed by the lumiphor, which then emits light, and at least a portion of any light emitted by the lumiphor directed toward the filter is reflected by the filter. Also, a method of lighting, comprising illuminating a solid state light emitter in such devices. Also, a lighting device, comprising a solid state light emitter; a lumiphor and filter means for allowing at least a portion of light emitted by the light emitter to pass through and for reflecting a second portion of light emitted by the lumiphor after the lumiphor is excited.
