Abstract
A lighting module comprising a light source of the LED type (not visible), a reflector with an elliptical reflective surface and a lens, the module being provided with means of quick-fastening to a mount. These means comprise a flange fitted with tabs (not visible) able to collaborate with corresponding notches of an orifice in the mount. This mounting allows the module to be fitted and removed very easily so that the light source or sources can be replaced, without disturbing the beam alignment. The invention also relates to the mount in question and to a corresponding headlamp.
Claims19
A lighting module comprising:
- at least one light source able to emit rays of light, said at least one light source being a light-emitting diode;
- at least one reflective surface able to reflect said rays of light emitted by said at least one light source as a light beam along an optical axis of said lighting module;
- wherein said lighting module further comprises quick-fastening means for fastening said lighting module to a mount;
- wherein said lighting module further comprises holding means or a holder arranged at a rear end of said lighting module on a cooling radiator for cooling said at least one light source, said holding means or holder being a rear face which, in a longitudinal cross section, has a profile with a projecting part suited to holding in the hand;
- said lighting module generating a lighting or signaling light for in a motor vehicle;
- and
- wherein said at least one reflective surface comprises an elliptical profile having a first focal point occupied by said at least one light source and a second focal point such that said rays of light emitted by said at least one light source at said first focal point are reflected by said at least one reflective surface toward said second focal point, said quick-fastening means being positioned longitudinally about said optical axis of said lighting module substantially between said second focal point and a front end of said lighting module generally level with said second focal point.
