Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
192 words
In an automobile vehicle, a support piece of bodywork of said vehicle having an opening therethrough, an elliptical reflector device having two foci mounted on the inner face of said piece of bodywork so that the optical axis of said elliptical reflector device extends transversely to said piece of bodywork and so that one of the two foci of the elliptical reflector device substantially merges with said opening, a first holding means for securing said reflector device in position on said piece of bodywork, a lamp having a filament disposed within the elliptical reflector device on the inner face of said piece of bodywork so that the filament merges with the other focus of the elliptical reflector device, a globe supported on the outer face of said piece of bodywork opposite said elliptical reflector device, and a second holding means securing said globe in position, said opening provided in said piece of bodywork being small with respect to the surface circumscribed on the inner face of said piece of bodywork by said elliptical reflector device but allowing substantially all the beam reflected by the elliptical reflector device to emerge from said opening.
Claim 2
Dependent Claim
192 words
In an automobile vehicle, a support piece of bodywork of said vehicle having an opening therethrough, an elliptical reflector device having two foci mounted on the inner face of said piece of bodywork so that the optical axis of said elliptical reflector device extends transversely to said piece of bodywork and so that one of the two foci of the elliptical reflector device substantially merges with said opening, a first holding means for securing said reflector device in position on said piece of bodywork, a lamp having a filament disposed within the elliptical reflector device on the inner face of said piece of bodywork so that the filament merges with the other focus of the elliptical reflector device, a globe supported on the outer face of said piece of bodywork opposite said elliptical reflector device, and a second holding means securing said globe in position, said opening provided in said piece of bodywork being small with respect to the surface circumscribed on the inner face of said piece of bodywork by said elliptical reflector device but allowing substantially all the beam reflected by the elliptical reflector device to emerge from said opening.
Claim 3
Dependent Claim
17 words
The system of claim 1 wherein the filament of the lamp is surrounded by a coloured filter.
Claim 4
Dependent Claim
16 words
The system of claim 1 wherein the reflecting surface of the elliptical reflector device is coloured.
Claim 5
Dependent Claim
30 words
The system of claim 1 wherein a coloured translucent screen is provided in the vicinity of the opening made in said piece of bodywork, between said filament and said opening.
Claim 6
Dependent Claim
30 words
The system of claim 1 wherein an opaque screen is provided between said filament and said opening to occult the light beam emitted directly by said filament toward the opening.
Claim 7
Dependent Claim
47 words
The system of claim 1 wherein the elliptical reflector device is formed by a portion of ellipsoid of revolution having an axis of revolution coaxial with said opening and transvere to said piece of bodywork and the opening in the piece of bodywork is circular in form.
Claim 8
Dependent Claim
50 words
The system of claim 1 wherein the elliptical reflector device is in the form of an elongated envelope provided with two arms substantially in U form of which the cross section constitutes a portion of an ellipse, and the opening made in the piece of bodywork is elongated in form.
Claim 9
Dependent Claim
146 words
The system of claim 1, wherein it comprises a plurality of reflector devices of the elliptical mirror type, each associated with a lamp to form elementary light-emitting devices which are fixed on the inner face of a piece of bodywork of said vehicle in a position such that the filament of each lamp is substantially disposed at the first focus of the elliptical mirror which is associated therewith, whilst the other focus of each of the elliptical mirrors merges substantially with an orifice provided in said piece of bodywork; the dimensions of this orifice, whilst being small with respect to the surface circumscribed on the piece of bodywork by the reflector, are defined so that virtually all the beam reflected by each elliptical mirror emerges from the light; and a translucent globe is fixed on the outer face of said piece of bodywork, opposite the reflectors.
Claim 10
Dependent Claim
38 words
The system of claim 1 in which said first holding means comprises orifices provided in said piece of bodywork, and catches projecting with respect to the body of said elliptical reflector device so as to enter said orifices.
Claim 11
Dependent Claim
39 words
The system of claim 1 in which said second holding means comprises screws for supporting said globe on the outer face of said piece of bodywork, and an O ring interposed between said globe and said piece of bodywork.
Claim 12
Dependent Claim
111 words
The system of claim 1 wherein said piece of bodywork has a plurality of openings therethrough a like number of elliptical reflector devices are supported on the inner face of said piece of bodywork with the respective optical axes of said elliptical reflector devices extending transversely to said piece of bodywork so that one of the two foci of the elliptical reflector devices respectively merges with one of said openings, and a like number of lamps each having a filament associated respectively with the elliptical reflector devices are supported on the inner face of said piece of bodywork, each filament merging with the other focus of the associated elliptical reflector device.
