Abstract
Abstract The arrangement transmits light energy from a light source by means of a stack of light-conducting members having surfaces which are approximately parallel to a common plane. The members are arranged around the light source and their outward ends define reflecting surfaces. Each member collects a portion of the light energy emanating from the light source and guides its portion of the collected light energy along a prescribed path to its reflecting surface.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
115 words
In an arrangement for transmitting the light energy radiated by a light source having an elongated light-producing means, and comprising a stack of light-conducting bodies having walls running in parallel to a common plane, said walls extending sidewards from said light source and having reflecting surfaces at their respective ends remote from said light source, the improvement wherein, said bodies are arranged around said light source, and said means is substantially perpendicular to said plane, whereby each one of said bodies collects only a portion of the light produced by said means and transmits the collected light to its reflecting surface, thereby allowing said bodies to substantially fully collect the light produced by said means.
Claim 2
Dependent Claim
115 words
In an arrangement for transmitting the light energy radiated by a light source having an elongated light-producing means, and comprising a stack of light-conducting bodies having walls running in parallel to a common plane, said walls extending sidewards from said light source and having reflecting surfaces at their respective ends remote from said light source, the improvement wherein, said bodies are arranged around said light source, and said means is substantially perpendicular to said plane, whereby each one of said bodies collects only a portion of the light produced by said means and transmits the collected light to its reflecting surface, thereby allowing said bodies to substantially fully collect the light produced by said means.
Claim 3
Dependent Claim
12 words
The arrangement according to claim 1 wherein, each light-conducting body is disc-shaped.
Claim 4
Dependent Claim
40 words
Arrangement according to claim 1, and a superposed Fresnel lens wherein the light energy transmitted by the reflecting surfaces of the light conducting bodies is supplied to the Fresnel lens which concentrates the light energy onto a common focal point.
Claim 5
Dependent Claim
16 words
The arrangement according to claim 3, and a circular cylindrical disc matched to said Fresnel lens.
Claim 6
Dependent Claim
17 words
The arrangement according to claim 3, and a light-conducting rod positioned to receive the concentrated light energy.
Claim 7
Dependent Claim
56 words
The arrangement according to claim 1, and a superposed circular lens disc having impressed, inclined circular ring surfaces with stepped different inclination angles, and the light energy transmitted by the reflecting surfaces is supplied to said circular lens disc whereby the light is transmitted by the inclined circular ring surfaces dependent upon the stepped inclination angles.
Claim 8
Dependent Claim
46 words
The arrangement according to claim 1, and a superposed circular ring disc having a number of concave circular surfaces, and a plurality of light-conductors arranged whereby the light transmitted by the reflecting surfaces of the light conducting bodies reaches the light conductors through the circular surface.
Claim 9
Dependent Claim
30 words
The arrangement according to claim 7, wherein said light conductors are cylindrical and concentric to each other, and each concave circular surface is operatively associated with a cylindrical light conductor.
Claim 10
Dependent Claim
24 words
Arrangement according to claim 1, wherein said reflecting surfaces of the light conducting bodies are arranged at different radial distances from said light source.
Claim 11
Dependent Claim
38 words
The arrangement according to claim 1, and at least one scattering lense positioned laterally relative to said light source such that the optical axis of said scattering lense coincides with the longitudinal axis of said elongated light-producing means.
Claim 12
Dependent Claim
36 words
The arrangement according to claim 1, and a collecting lense positioned laterally relative to said light-conducting bodies such that the optical axis of said collecting lense coincides with the longitudinal axis of said elongated light-producing means.
Claim 13
Dependent Claim
39 words
The arrangement according to claim 1, wherein at least one of said light-conducting bodies has a projection which is substantially perpendicular to said common plane, and the reflecting surface of said one light-conducting body is opposite to said projection.
Claim 14
Dependent Claim
12 words
The arrangement of claim 12, wherein said projection has a chamfered edge.
Claim 15
Dependent Claim
14 words
The arrangement according to claim 12, wherein the end of said projection is concave.
Claim 16
Dependent Claim
14 words
The arrangement according to claim 12, wherein the end of said projection is convex.
