Lighting device and lighting method
First Claim
1. A lighting device, comprising:
- at least a first solid state light emitter;
at least a first light filter, andat least a first luminescent material-containing structure,said first solid state light emitter and said first light filter being positioned relative to one another such that if said first solid state light emitter is illuminated, said first solid state light emitter will emit first solid state emitter light, and at least a portion of said first solid state emitter light will exit said first light filter,said first light filter allowing passage of at least some light having wavelength within a first solid state emitter range of wavelength and reflecting at least some light having wavelength outside said first solid state emitter range of wavelength, said first solid state emitter range of wavelength consisting of wavelengths of light emitted by said first solid state light emitter if said first solid state light emitter is illuminated, such that if said first solid state light emitter is illuminated so that said first solid state light emitter emits said first solid state emitter light, at least a portion of said first solid state emitter light will pass through said first light filter,said first light filter in direct contact with said first solid state light emitter,said first luminescent material-containing structure spaced from said first light filter.

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.

20. A method of lighting, comprising:
-
illuminating at least a first solid state light emitter to produce first solid state light emitter light, said first solid state light emitter being positioned relative to a first light filter such that at least a first portion of said first solid state emitter light passes through said first light filter, said first solid state light emitter and said first light filter being positioned relative to a first lumiphor such that at least some of said first portion of said first solid state emitter light is absorbed by said first lumiphor, thereby exciting said first lumiphor and causing said first lumiphor to emit first lumiphor light, and at least a portion of said first lumiphor light is reflected by said first light filter, said first light filter in direct contact with said first solid state light emitter, said first lumiphor spaced from said first light filter. - View Dependent Claims (21, 22, 23)

24. A lighting device, comprising:
-
at least a first solid state light emitter; at least a first lumiphor; and filter means for allowing at least a first portion of light emitted by said first solid state light emitter to pass through and for reflecting at least a second portion of light which is emitted by said first lumiphor after said first lumiphor is excited by at least part of said first portion of light. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)
