LIGHTING DEVICE AND LIGHTING METHOD

摘要

A lighting device (10), comprising a solid state light emitter (11) and a light filter (12). At least a portion of light emitted by the light emitter (11) contacts the filter (12), and at least part of the light passes through the filter (12). Also, such lighting devices further comprising luminophoric material (13), in which at least some of the first part of the light is absorbed by the luminophoric material (13), which then emits light, and at least a portion of any light emitted by the luminophoric material (13) directed toward the filter (12) is reflected by the filter (12). Also, a method of lighting, comprising illuminating a solid state light emitter (11) in such devices. Also, a lighting device, comprising a solid state light emitter (11); a luminophoric material (13) and filter (12) means for allowing at least a portion of light emitted by the light emitter (11) to pass through and for reflecting a second portion of light emitted by the luminophoric material (13) after the luminophoric material (13) is excited.
