Abstract
Abstract A luminescent solar collector comprising at least one luminescent member which has at least one photovoltaic means operably associated therewith, the luminescent member having a side which is to be essentially oriented toward the sun when in operation, and an optically transparent member on the sun-facing side of the luminescent member, the transparent member being spaced from the sun-side to provide space between the luminescent member and the transparent member, the transparent member being essentially coextensive with the luminescent member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
88 words
A luminescent solar collector comprising at least one luminescent member having at least one photovoltaic means operably associated therewith, said photovolatic means being physically removed from said luminescent member and optically coupled with said luminescent member by optic means, said luminescent member having at least one side which is adapted to be oriented toward the sun and an edge face, a light transparent member carried adjacent to and in spaced relation from said sun-side of said luminescent member, said transparent member being essentially coextensive with said luminescent member.
Claim 2
Dependent Claim
88 words
A luminescent solar collector comprising at least one luminescent member having at least one photovoltaic means operably associated therewith, said photovolatic means being physically removed from said luminescent member and optically coupled with said luminescent member by optic means, said luminescent member having at least one side which is adapted to be oriented toward the sun and an edge face, a light transparent member carried adjacent to and in spaced relation from said sun-side of said luminescent member, said transparent member being essentially coextensive with said luminescent member.
Claim 3
Dependent Claim
43 words
A collector according to claim 1 wherein at least part of the photovoltaic means are carried on the underside of said luminescent member, and the area of said underside which is not covered by photovoltaic means is essentially covered by thermal insulation means.
Claim 4
Dependent Claim
21 words
A collector according to claim 1 wherein at least part of said edge face of said luminescent member carry reflective means.
