Abstract
Abstract A coloured direction indicator lamp (1) is provided frontally with a colourless transparent element (2) and comprises an elliptical reflector (6), a light source (11) located at the rear focal point (F1) of the reflector, a coloured filter (7, 16) for imparting the desired colour to the rays of light emitted by the light source (11) and reflected by the reflector (6), and screenlng means (12, 13, 15, 18) between the two focal points (F1, F2) of the elliptical reflector (6) to prevent the direct rays of light emitted by the light source (11) from reaching the transparent element (2) and to substantially prevent the coloured filter (7, 16) from being seen from the exterior.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
Direction indicator lamp for motor vehicles adapted to emit a beam of coloured light, characterised in that it comprises a casing (1) which is closed at the front by a colourless transparent element (2), the casing housing: - a cup-shaped elliptical reflector (6) having its edge (6a) facing the transparent element (2); - a light source (11) located at the rear focal point (F1) of the elliptical reflector (6); - a coloured filter (7,16) for imparting the desired colour to the rays of light emitted by the light source (11) and reflected by the reflector (6), and - screening means (12,13,15,18) between the two focal points (F1,F2) of the elliptical reflector (6) to prevent the direct rays of light emitted by the light source (11) from reaching the transparent element (2) and to substantially prevent the coloured filter (7,16) from being seen from the exterior.
Claim 2
Dependent Claim
145 words
Direction indicator lamp for motor vehicles adapted to emit a beam of coloured light, characterised in that it comprises a casing (1) which is closed at the front by a colourless transparent element (2), the casing housing: - a cup-shaped elliptical reflector (6) having its edge (6a) facing the transparent element (2); - a light source (11) located at the rear focal point (F1) of the elliptical reflector (6); - a coloured filter (7,16) for imparting the desired colour to the rays of light emitted by the light source (11) and reflected by the reflector (6), and - screening means (12,13,15,18) between the two focal points (F1,F2) of the elliptical reflector (6) to prevent the direct rays of light emitted by the light source (11) from reaching the transparent element (2) and to substantially prevent the coloured filter (7,16) from being seen from the exterior.
Claim 3
Dependent Claim
20 words
An indicator lamp according to Claim 1, characterised in that the coloured filter (7) is incorporated in the reflector (6).
Claim 4
Dependent Claim
32 words
An indicator lamp according to Claim 2, characterised in that the coloured filter (7) is formed by a coloured filtering layer (7) superimposed on the reflective surface (8) of the reflector (6).
Claim 5
Dependent Claim
86 words
An indicator lamp according to Claims 2 and 3, characterised in that the screening means comprise an annular element (12,13) which extends as an extension of the edge (6a) of the reflector (6), and a central disc (15) which is carried on the internal edge of the annular element (12,13) by support rods (14) and has a diameter less than that of the central opening of the annular element (12,13), said disc (15) lying substantially in the plane of the edge (6a) of the reflector (6).
Claim 6
Dependent Claim
56 words
An indicator lamp according to Claim 4, characterised in that the annular element (12,13) comprises a frusto-conical side wall (12) which converges towards the transparent element (2), and a flat annular wall (13) which is parallel to the disc (15) and extends along the inside of the smaller diameter end of the frusto-conical side wall (12).
Claim 7
Dependent Claim
20 words
An indicator lamp according to Claim 1, characterised in that the coloured filter (16) is separate from the reflector (6).
Claim 8
Dependent Claim
38 words
An indicator lamp according to Claim 6 , characterised in that the coloured filter (16) is carried by the screening means (12,13),and in that the screening means (12,13) are carried by the edge (6a) of the reflector (6).
Claim 9
Dependent Claim
60 words
An indicator lamp according to Claim 7, characterised in that the screening means comprise an opaque annular element (12,13) extending as an extension of the reflector (6), and an opaque central disc (15) carried peripherally on the internal edge of the annular element (12,13) by means of a frusto-conical tubular coloured filter (16) which converges towards the light source (11).
Claim 10
Dependent Claim
48 words
An indicator lamp according to Claim 8, characterised in that the opaque annular element (12,13) has a frusto-conical tubular projection (18) opposite the frusto-conical tubular coloured filter (16) and converging towards the front focal point (F2) of the reflector (6), to screen the coloured filter (16) from view.
Claim 11
Dependent Claim
27 words
An indicator lamp according to Claim 8, characterised in that the surface (17) of the central screening disc (15) facing the transparent element (2) is painted silver.
