Abstract
Abstract A luminaire which has in its housing a multiplicity of groups of light emitters of different colors or pluralities of optical waveguides constructed to emit light progressively along the lengths thereof and a diffuser at which the colors can be mixed and from which the light emerges. The emitters can be controlled at the housing or light can be delivered to the optical waveguides by optical fibers from remote light sources.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
89 words
A luminaire, comprising: a housing; a light-transmissive diffuser extending across said housing for diffusing light impinging upon said diffuser from within said housing; a multiplicity of spaced apart elongated light guides in said housing emitting light continuously over respective lengths thereof, each of said light guides being cladded optical fiber having a cladding removed over a portion of a periphery thereof and for the entire respective length of light emission therefrom; and means at an end of said housing or injecting light into corresponding ends of said light guides.
Claim 2
Dependent Claim
89 words
A luminaire, comprising: a housing; a light-transmissive diffuser extending across said housing for diffusing light impinging upon said diffuser from within said housing; a multiplicity of spaced apart elongated light guides in said housing emitting light continuously over respective lengths thereof, each of said light guides being cladded optical fiber having a cladding removed over a portion of a periphery thereof and for the entire respective length of light emission therefrom; and means at an end of said housing or injecting light into corresponding ends of said light guides.
Claim 3
Dependent Claim
48 words
The luminaire defined in claim 1 wherein said light guides are grouped in groups of light guides emitting light of different complementary colors, said colors mixing at said diffuser, said means at said end of said housing controllably injecting light of corresponding color into the respective light guides.
Claim 4
Dependent Claim
22 words
The luminaire defined in claim 1 wherein said housing said light guides and said diffuser are flexible allowing bending of the luminaire.
Claim 5
Dependent Claim
23 words
The luminaire defined in claim 1 wherein said light guides are disposed in a plane parallel to a specularly or diffusely reflective surface.
Claim 6
Dependent Claim
19 words
The luminaire defined in claim 4 wherein said light guides are disposed adjacent said specularly or diffusely reflective surface.
Claim 7
Dependent Claim
19 words
The luminaire defined in claim 4 wherein said light guides are spaced from said specularly or diffusely reflective surface.
Claim 8
Dependent Claim
39 words
The luminaire defined in claim 1 wherein said means at an end of said housing for injecting light into corresponding ends of said light guides includes at least one light emitter in said housing assigned to each light guide.
Claim 9
Dependent Claim
16 words
The luminaire defined in claim 7, further comprising means for cooling said end of said housing.
Claim 10
Dependent Claim
46 words
The luminaire defined in claim 1 wherein said means at an end of said housing for injecting light into corresponding ends of said light guides includes at least one light source remote from said housing and fiber optics optically connecting said source with said light guides.
Claim 11
Dependent Claim
34 words
The luminaire defined in claim 9 wherein said light source includes respective sources of light of different colors to be mixed at said diffuser and delivered to respective light guides by said fiber optics.
Claim 12
Dependent Claim
17 words
The luminaire defined in claim 9 wherein said housing is water-tight and the luminaire is water immersible.
Claim 13
Dependent Claim
26 words
The luminaire defined in claim 9 wherein said luminaire is one of a plurality of luminaires connected to a common light source by said fiber optics.
Claim 14
Dependent Claim
16 words
The luminaire defined in claim 11 wherein said diffuser forms a wall of a bathing facility.
Claim 15
Dependent Claim
34 words
The luminaire defined in claim 1, further comprising a light source connected to each of said light guides and selected from the group which consists of LEDs, laser diodes, gas discharge and HID sources.
Claim 16
Dependent Claim
25 words
The luminaire defined in claim 1 wherein at least one of said light guides is provided with at least one optical element forming collection optics.
Claim 17
Dependent Claim
72 words
A luminaire, comprising: an inflatable and deflatable housing; a light-transmissive diffuser extending across said housing for diffusing light impinging upon said diffuser from within said housing; a multiplicity of elongated light guides in said housing emitting light over respective lengths thereof; means at an end of said housing for injecting light into corresponding ends of said light guides; and means for introducing a gas into and removing a gas from said housing.
