Abstract
Abstract A light distributing assembly such as a direction lamp utilizing a fluorescent plastic member which is capable of emitting light from its ends or edges when a light source is impinged on its surface combined with a cylindrical dowel, rod, spherical ball, reflector or the like which will pick up a substantial portion of the light emitted from the end or edge and direct such light in a restricted direction while concentrating the light into a beam capable of use in many orientations.

Claim 1
Independent Claim
146 words
A controlled light distributing unit comprising a fluorescent plastic member having a terminal light emitting surface emitting light therefrom in response to sunlight impinging upon a surface with the sunlight impinging surface being larger than the terminal light emitting surface, and a transparent, light collecting and distributing member having a curved surface in spaced, adjacent and aligned relation to the terminal light emitting surface of the fluorescent plastic member for receiving light emitted therefrom and a curved surface opposite from the terminal light emitting surface for emitting the received light therefrom, said fluorescent plastic member being a substantially flat circular sheet with the peripheral edge thereof defining the terminal light emitting surface, said light collecting and distributing member being an annular ring having a circular cross section disposed in adjacent spaced aligned concentric relation with the peripheral edge of the circular sheet and receiving light therefrom.
Claim 2
Dependent Claim
146 words
A controlled light distributing unit comprising a fluorescent plastic member having a terminal light emitting surface emitting light therefrom in response to sunlight impinging upon a surface with the sunlight impinging surface being larger than the terminal light emitting surface, and a transparent, light collecting and distributing member having a curved surface in spaced, adjacent and aligned relation to the terminal light emitting surface of the fluorescent plastic member for receiving light emitted therefrom and a curved surface opposite from the terminal light emitting surface for emitting the received light therefrom, said fluorescent plastic member being a substantially flat circular sheet with the peripheral edge thereof defining the terminal light emitting surface, said light collecting and distributing member being an annular ring having a circular cross section disposed in adjacent spaced aligned concentric relation with the peripheral edge of the circular sheet and receiving light therefrom.
Claim 3
Dependent Claim
141 words
A controlled light distributing unit comprising a fluorescent plastic member having a terminal light emitting surface emitting light therefrom in response to sunlight impinging upon a surface with the sunlight impinging surface being larger than the terminal light emitting surface, and a transparent, light collecting and distributing member having a curved surface in spaced, adjacent and aligned relation to the terminal light emitting surface of the fluorescent plastic member for receiving light emitted therefrom and a curved surface opposite from the terminal light emitting surface for emitting the received light therefrom, said fluorescent plastic member being a substantially flat polygonal sheet with the peripheral edge thereof forming the terminal light emitting surface, said light collecting and distributing member being a continuous ring disposed in adjacent spaced aligned concentric relation with the peripheral edge of the polygonal sheet and receiving light therefrom.
Claim 4
Dependent Claim
141 words
A controlled light distributing unit comprising a fluorescent plastic member having a terminal light emitting surface emitting light therefrom in response to sunlight impinging upon a surface with the sunlight impinging surface being larger than the terminal light emitting surface, and a transparent, light collecting and distributing member having a curved surface in spaced, adjacent and aligned relation to the terminal light emitting surface of the fluorescent plastic member for receiving light emitted therefrom and a curved surface opposite from the terminal light emitting surface for emitting the received light therefrom, said fluorescent plastic member being a substantially flat polygonal sheet with the peripheral edge thereof forming the terminal light emitting surface, said light collecting and distributing member being a continuous ring disposed in adjacent spaced aligned concentric relation with the peripheral edge of the polygonal sheet and receiving light therefrom.
Claim 5
Dependent Claim
162 words
A controlled light distributing unit comprising a fluorescent plastic member having a terminal light emitting surface emitting light therefrom in response to sunlight impinging upon a surface with the sunlight impinging surface being larger than the terminal light emitting surface, and a transparent, light collecting and distributing member having a curved surface in spaced, adjacent and aligned relation to the terminal light emitting surface of the fluorescent plastic member for receiving light emitted therefrom and a curved surface opposite from the terminal light emitting surface for emitting the received light therefrom, said fluorescent plastic member being a flat sheet defined by parallel unequal length leg portions connected by a curved bight portion with the edges of the member facing in the same direction defining terminal light emitting edges, said light collecting and distributing member being a pair of equal diameter cylindrical rods disposed in spaced parallel relation to the terminal light emitting edges of the fluorescent plastic sheet and receiving light therefrom.
