- the lens can be arranged in such a way that its focus backward, including about 1.5 mm back, from the fireplace outer of the ellipsoidal reflector.
- the ellipsoidal reflector can be located below of the horizontal plane passing through the transverse axis of the light source and parallel to the optical axis of the reflector, while the verticalized projector is located above this plane. This provision is advantageous in the where the light source is a discharge lamp.
- a projector illuminated P for a motor vehicle having a source S transversal that is to say whose geometric axis is horizontal and orthogonal to the Y-Y optical axis of the projector.
- the source S may consist of a halogen lamp having a generally cylindrical filament.
- this lamp is mounted transversely in the projector while in the case of a lamp standardized H3 with cross filament, this H3 lamp is mounted axially in the projector.
- the source S may consist of a lamp discharge producing a generally cylindrical arc whose axis geometric mean is perpendicular to the plane of FIG. 1.
- the source S is placed in the vicinity of the internal focus Fi of a ellipsoidal reflector R1.
- ellipsoidal reflector is meant a reflector whose surface is defined from two foci respectively an internal focal point Fi and an external focus Fe, this surface is closer to an ellipsoid without necessarily being exactly a ellipsoid.
- the wall of the ellipsoidal reflector R1 has an indentation 1 on one side of the plane passing through the geometric axis of source S and parallel to the Y-Y optical axis.
- the plane in question is the horizontal plane passing through the geometric axis of the source S.
- the notch 1 corresponds substantially to a cut of half lower reflector R1 by an oblique plane.
- the cutting plane is slightly inclined from left to right of Fig.1.
- Plan view, according to 3 the indentation 1 is limited by two edges converging towards the rear from the source S.
- the rear ends of the edges of the indentation 1 are connected by a segment orthogonal to the Y-Y axis.

- optical axis of the ellipsoidal reflector R1 is confused with the Y-Y optical axis of the projector.
- the diameter of the lens 2 may be about 50 mm.
- the lens 2 is preferably of small size (by “pull” is meant the distance between the lens and the external focus Fe of R1).
- the accessory parts of the headlamp in particular ice-cream closure and auxiliary equipment to maintain reflector, lens, light source and other parts, are not shown because known in themselves.

- the optical axis 4 of the lens 2 is located more down as the optical axis Y-Y.
- the vertical distance h between the optical axis 4 of the lens 2 and the optical axis Y-Y is about 1.5 mm which allows to recover more luminous flux coming from the reflector R1.
- the filament of the S lamp can be located vertically above of the internal fireplace Fi to increase the luminous flux from the ellipsoidal reflector R1.
- the projector P is intended to provide the function code that is to say to provide a beam crossing.
- a cover 5 is disposed in the vicinity of the focus outer cover Fe.
- the cover 5 is constituted by an opaque plate, by metal example, maintained by any appropriate means. Due to the curvature of the field, the cover 5 forms a portion of surface cylindrical vertical generatrices turning its concavity forward.
- the upper edge of the cover 5 is located below the horizontal plane passing through Y-Y at a distance of about 1.5 mm.
- a verticalized reflector R2 is arranged on the side of the notch 1 opposite most of the ellipsoidal reflector R1. The intersection of this verticalized reflector R2 by a vertical plane passing through the Y-Y axis is formed by a curve arc next to a parabola bow having a focus neighbor of the internal focus Fi.
- the surface of the reflector R2 is determined so that a light ray such as 6i from source S is reflected in 6th following a direction parallel or substantially parallel to the Y-Y axis.
- the verticalized reflector R2 is intended to give images of the source S centered on the Y-Y axis at infinity, that is to say at a distance several tens of meters from the projector.
- the verticalized reflector R2 is intended to concentrate the beam that it reflects in an opening angle A (Fig.3) at most equal at ⁇ 20 ° on both sides of the Y-Y optical axis.
- the reflector R2 can have streaks C1, C2 defining at least three facets, namely a central facet 7 constituted by a cylindrical surface portion whose generators are horizontal and perpendicular to the plane of Fig.1, and two side facets 8, 9 slightly folded towards each other compared to the central facet 7.
- the central facet 7 of the reflector vertically contributes to the range of the beam while the lateral facets 8, 9 contribute to widening the beam reflected by R2.
- the housing K projector schematized on Fig.2 with a rectangular outline, can be higher than wide.
- the ellipsoidal reflector R1 produces a light beam having an opening angle B (Fig.3) of approximately ⁇ 40 ° on either side of the axis Y-Y optics.
- the verticalized reflector R2 is intended to establish the V-cut line, corresponding to the regulation of codes, as will be described in Fig.5.
- the operation of the projector P is as follows.
- the ellipsoidal reflector R1 When the light source S is in operation, the ellipsoidal reflector R1 produces a beam of reduced range but wide, to illuminate the aisles.
- Isolux illumination curves of this beam on a screen perpendicular to the Y-Y optical axis and located 25 m from the projector are represented in FIG. 4, for a particular nonlimiting example.
- the axis abscissa corresponds to the trace on the screen of the horizontal plane passing by the Y-Y optical axis of the projector.
- the graduations in% (percent) on this axis corresponds to the tangent of the angle formed between the optical axis and the right going through the focus of the projector and cutting the screen to the level of graduation.
- the ordinate axis corresponds to the trace on the screen of the vertical plane passing through the optical axis Y-Y.
- the graduations in% (for cent) of this vertical axis correspond to the tangent of the formed angle between the horizontal plane passing through the optical axis and a straight line through the projector's focus and off the screen at the point of graduation.
- the isolux curves of the beam produced by the reflector R1 are located essentially below the horizontal plane passing through the optical axis Y-Y.
- the closed curve L1 of maximum illumination is entirely below the plane horizontal and is substantially symmetrical with respect to the vertical axis.
- This curve L1 is surrounded by a series of closed curves corresponding to ever weaker illuminations. Some of these curves extend laterally up to ⁇ 70% (corresponding to angles of about ⁇ 35 ° / tg 35 ° ⁇ 0.7).
- the isolux curve L1 corresponds, in the example under consideration, to a illumination of 6 lux.
- the maximum illumination is at the center of this curve.
- the following isolux curves correspond to illuminations which gradually decrease: 3.2 lux for L2, 1.6 lux for L3, 0.7 lux for L4, 0.4 lux for L5, 0.2 lux for L6.
- the total flux of the beam produced by the reflector ellipsoidal R1 is about 254 lumens.
- FIG. 5 represents, for the example under consideration, the isolux curves the light beam provided by the verticalized reflector R2 alone.
- the beam is more concentrated than that of Fig.4 with a cutoff line in V, substantially horizontally to the left of the y-axis and amount to the right along an inclined branch 10.
- the closed curve isolux of higher illumination V1 is crossed by the vertical axis and extends a little more to the right than to the left, likewise for other isolux curves.
- This curve V1 corresponds to an illumination of 32 lux.
- isolux curves V2, V3, V4, V5, V6, V7, V8, V9 and V10 correspond respectively to levels of 24 lux, 20 lux, 16 lux, 12 lux, 6 lux, 3,2 lux, 1,6 lux, 0,7 lux and 0,4 lux.
- the high illumination of this beam along the axis reflects the range larger than that of the more spread beam (Fig.4) of the reflector ellipsoidal.
- Fig.6 illustrates the isolux curves of the projector obtained by addition of the respective beams of the ellipsoidal reflector R1 and the verticalized reflector R2. Still for the example considered, the curve LV1 central isolux corresponds to a level of 32 lux. The curves surrounding areas correspond to decreasing levels gradually. The LV5 curve corresponds to a level of 12 lux and the LV10 curve at a level of 0.4 lux.
- the curves of Fig.6 correspond to a beam bright crossover located, for the left side, basically below of the horizontal plane passing through the optical axis, with a line of oblique cut on the right side rising above the horizontal.
- the ellipsoidal reflector R1 is located mainly above the horizontal plane passing through the axis the projector's Y-Y optic, the notch 1 being located below this plane, as well as the verticalized reflector R2.
- the invention applies not only to a projector of crossing P such as the one described, but also to other types of projectors, including a road searchlight. In the latter case the cache 5 would be deleted and there would be no need for lines cutoff for the light beams.
- the presence of the verticalized reflector R2 allows, in the case of a crossover projector with cover 5, a better performance in flow compared to a projector with a single ellipsoidal reflector full.
- the gain in flux is of the order of 25% because the light beam produced by the verticalized reflector R2 is not diminished by the cache 5.
