    A motor vehicle headlamp, of the type capable of creating a main beam, and a dipped beam limited by a cutoff, comprises two axial filaments 11, 12 aligned on the optical axis Ox of the headlamp, and acting as light sources respectively for the main beam and for the dipped beam, a reflector 200 and a closure glass 30. According to the invention, the reflector is divided into two lateral zones 202, 203 and a central zone 201, the lateral zones are paraboloid portions whose foci Fo are situated on the optical axis between the two filaments, the central zone is a zone which reflects the light rays emitted by the filament so that they converge in a region substantially distant from the closure glass, and the central zone and the lateral zones are connected with continuity in two substantially vertical planes situated on either side of the optical axis of the headlamp. Application to attenuating the intensity of the dipped beam at the centre of the glass, and to spreading the beam sideways. <IMAGE>

    The invention is ttnositsya to lighting, namely .. car headlights, forming a beam of high and low beam.
    The aim of the invention is to reduce the labor intensity of manufacturing the headlamp and improving the technical characteristics.
    On fng.1 shows a headlight, a horizontal cut; figure 2 is the same, front view; from fng. Z - headlight, version; FIG. 4 is the same, front view; FIG. 5 shows curves of equal values of the luminous intensity of the formed beam of the headlight shown in FIG. 3, without a gassenoztel; FIG. on

    The headlight of an automobile vehicle contains a lamp with a high-beam incandescent body, a low-beam incandescent body 2, a screen 3, a reflector 4 n a diffuser 5. The reflector 4 consists of two parabond elements 6 n 7 n of the central zone 8, which is connected to elements 6 n 7 in vertical planes parallel to the optical axis OX. Central zone 8 at-y. y Ј O corresponds to the equation

    The headlight of the motor vehicle sports track works as follows.
    The light beam of the body of the impudent neighbor e &amp; eta, reflecting from aeons 8, 9 and 10 of Hartel 4, forms a light beam, the highest concentration of light flux of which lies outside the dispersant 5 thereby reducing the thermal heat of the ravoviatel 5.
    In zones b, 9, and 10, according to equations (1) and (2), it is possible to obtain a smooth poison 4, which
