Definitions

  • the present invention relates to a direction indicator lamp for motor vehicles adapted to emit a beam of coloured light.
  • the invention is concerned with a lamp of the aforesaid type for mounting at the front of a motor vehicle adjacent a headlamp.
  • the light is normally coloured by using a coloured transparent element as the front closure element of the lamp casing.
  • this coloured transparent element contrasts with the colourless transparent element of the adjacent headlamp and thus fails to meet those styling requirements which call for the headlamp and the adjacent direction indicator lamp to be harmonised into virtually a single unit.
  • the present invention seeks to avoid such a drawback by providing a front direction indicator lamp for motor vehicles adapted to emit a beam of coloured light, characterised in that it comprises a casing which is closed at the front by a colourless transparent element, the casing housing:
  • the casing 1 of a front direction indicator lamp for motor vehicles is closed at the front by a colourless transparent element 2.
  • the casing 1 is closed at the rear by a closure element 3 secured by screws 4 with the interpositioning of a sealing gasket 5.
  • the casing 1 contains an elliptical reflector, generally indicated 6, having focal points F1, F2 respectively.
  • the elliptical reflector 6 is formed by a main part 7 which is moulded from transparent plastics material coloured according to the colour of the light, for example yellow, which must be emitted by the indicator lamp in accordance with current regulations.
  • the external surface of the part 7 has a reflective layer 8 which is applied by metallization or lacquering.
  • the elliptical reflector 6 is provided with a tubular projection 9 at the rear, enabling it to be fixed to the casing 1.
  • the closure element 3 is provided with a tubular projection 10 which serves as a support for a bulb 11 the filament of which is in correspondence with the rear focal point F1 of the elliptical reflector 6.
  • a screen is fixed to the front edge 6a of the elliptical reflector 6 and comprises a frusto-conical element 12 which converges towards the transparent element 2, a flat annular wall 13 which lies in a plane perpendicular to the line passing through the two focal points F, F1, F2, and a central disc 15 carried by three inclined rods 14 on the internal edge of the annular wall 13.
  • the disc 15 has a diameter less than the internal diameter of the annular wall 13 and lies in a plane substantially coincident with that of the edge 6a of the reflector 6.
  • the parts 12,13,14,15 are conveniently made in a single piece by moulding from a white opaque plastics material, and form a screen which allows only those rays emitted by the bulb 11 which are reflected by the reflector 6 and coloured by passing through the part 7 acting as a filter, to pass towards the transparent element.
  • the rays emitted by the bulb 11 directly towards the transparent element 2, however, are intercepted by the screen, which also serves to substantially prevent the coloured internal surface of the reflector 6 from being seen from the exterior (particularly by anyone observing the lamp along the line joining the focal points F1, F2).
  • the main part 77 of the elliptical reflector 6 is provided on its internal surface with a reflective layer 88 obtained,for example, by metallizing or painting,so that the light rays emitted by the bulb 11 and reflected by the reflector 6 are no longer coloured as in the preceding example.
  • a coloured (for example, yellow) filter 16 which has a frusto-conical, tubular shape and is interposed between the internal edge of the annular wall 13 and the disc 15.
  • the disc 15 is formed in a separate piece from the parts 12, 13 and is carried by the filter 16.
  • the surface of the disc 15 which faces the transparent element 2 is preferably painted silver.
  • the annular wall 13 has a frusto-conical tubular projection 18 in correspondence with its internal edge, which opposes the coloured filter 16 and converges towards the front focal point of the reflector.
