    This invention relates to lighting engineering, in particular to additional vehicle Laram vehicles, which, together with dipped-beam headlamps, create a driving beam.
    The purpose of the invention is to improve the manufacturability and lighting characteristics.
    FIG. 1 shows schematically an additional automobile headlight, a longitudinal vertical section (in Fig. 2 - the same, rear view of fig. 3 - 5 - a filament body for different, characteristic parts of the reflector; in Fig. 6 - a set of insulux headlights without a diffuser / 7 - diffuser, rear view in Fig. 8 - set of isolux headlights.
    An additional car headlight contains a lamp with an axial body of heat 1, a reflector 2 and a diffuser 3. Reflector 2 consists of two parabolic sectors 4 and 5, located symmetrically with respect to the headlight axis and bounded by inclined at an angle at half planes, focus fc of each sector 4 and 5 is located in the middle of the body 1 of the heat, as well as from sectors b - 9.
    Sectors 6 and 7 are located in the upper part of the reflector, connect sectors 4 and 5 and satisfy the equation

    1. An additional car headlight containing an axially incandescent lamp, a reflector with two paraboloid sectors, bounded by half-planes, tilted at the same angle relative to the horizontal plane passing through the headlight axis, and whose foci coincide with the incandescent body, and the lens, o - that, in order to improve manufacturability and lighting characteristics, the reflector is equipped with two additional sectors located between the parabolic sectors, with additional sectors correspond to the equations for the upper sector:
    where is the parameter that determines the displacement of the center of the images of the filament body, created by sectors 8 and 9,
    approximately equal to /) f c.
    The diffuser 3 consists of zones 10 - 25. Zones 10 and 11 are non-diverting, smooth. Zones 12-23 have grooves for a slight horizontal deviation. Zones 24 and 25 are highly divergent.
    An additional car headlight works in the following way.
    The images of the filament body, created by the paraboloid sectors 4 and 5 (Fig. 3), are located in the area of the trace of the headlight axis H, and all of the above images are oriented between - ol. and fc / relative to the horizontal h Hh.
    Sectors 6 and 8 create images (Fig. 4 and 5) of the filament body, the centers of which are located above the horizontal of h llh. The images created by sectors 7 and 9 will be symmetrical to the images of sectors 6 and 8 relative to the vertical plane v HV. The total beam, without taking into account the scatterer (Fig. 6), creates a spot with a higher level immediately above the horizontal 55 nb. After passing the diffuser (Fig. 8), it is evenly distributed in the horizontal direction.
