Embodiment Construction

[0030] figure 1 is a perspective view of a lamp module according to the present invention. The lamp module 2 mainly includes a support 4 , a first reflector 6 , a second reflector 8 and a third reflector 10 .

[0031] The first reflector 6 forms an elliptical first reflective surface 12 . More specifically, the reflective surface 12 forms an elliptical dome. The first reflector 6 may also comprise side walls extending to a transverse support 14 comprising a cutting edge 16 . More precisely, the cutting edge 16 in question is located at the second focal point of the first reflective surface 12 .

[0032] The second reflector 8 forms a second reflective surface 18 . This advantageously forms a parabolic dome, the focal point of which coincides with the second focal point of the first reflective surface 12 .

[0033] The third reflector 10 located below the second reflector 8 forms an elliptical reflective surface in a similar manner to the first reflector 6 .

Abstract

The invention relates to a lamp module (2), in particular for a motor vehicle, comprising a first reflective surface (12) of oval shape, said first reflective surface (12) having a first focal point (f 1 ) and the second focal point (f 2 ); a parabolic second reflective surface (18) having a second focal point (f 2 ) corresponding focal point; the first focal point (f 1 ) The light emitted by the first light source (24) at the place is reflected by the first reflective surface (12) and the second reflective surface (18) to form the first light beam; and the third reflective surface (20), the third reflective surface (20) and the second focal point (f 2 ) adjacent and configured to reflect light emitted by the second light source (28) toward the second reflective surface (18) to form a second light beam.

Description

technical field [0001] The invention relates to the field of lighting and light signaling, especially for motor vehicles. Background technique [0002] Published patent document FR 2 849 158 A1 discloses a lighting module for vehicle headlamps, mainly comprising an elliptical first reflective surface having a first focal point and a second focal point; and a parabolic The second reflective surface has a focal point corresponding to the second focal point of the first reflective surface. Light rays emitted by the light source at the first focal point of the first reflective surface are reflected towards the second reflective surface, passing through the second focal point. These rays are then reflected in the same direction by the parabolic second reflective surface. The module also includes a generally planar reflective surface having a cut edge passing through the second focal point. Light rays encountering this surface near the second focal point at an angle of incidenc...
