  • Patent number: 10829031
    Abstract: A headlamp assembly for a motor vehicle comprising at least one headlamp, which has a light source for emitting visible light, a radiation source for emitting infrared radiation, and a light emission optics with a light entry surface, which visible light from the light source and infrared radiation from the radiation source strikes, and which has an optical exit-deflection element, which directs the infrared radiation from the radiation source toward the light entry surface of the light emission optics. The optical exit-deflection element comprises at least one optics, which broadens the infrared radiation emitted by the radiation source to form a radiation beam with a cross section broadened in a horizontal plane (HH), and a radiation distribution that has at least one intensity maximum disposed toward the edge in the radiation distribution, to one side of a vertical plane (VV), when viewed in a focal plane of the light emission optics.

  • Patent number: 9249943
    Abstract: The present invention is directed toward a light module for a motor vehicle headlamp having a primary lens which conducts light emitted by a light source to an intermediate light distribution, wherein an aperture shutter is disposed in relation to a secondary lens such that light in the intermediate light distribution, which passes by the aperture shutter on a first side of the aperture shutter, ends up in a first beam path in a region lying on a first side of the light/dark border in the second light distribution. The primary lens deflects a portion of the light emitted from the light source, such that it passes by the aperture shutter on a second side of the aperture shutter, and is distributed by the secondary lens in a second beam path in a region lying on a second side of the light/dark border in the second light distribution.

  • Publication number: 20130201712
    Abstract: A headlight for a motor vehicle composes at least two semiconductor-light sources and a plurality of light refractors and/or reflecting optics. Light of each of the semiconductor-light sources is directed into a front area of the headlight such that the light produces at the front area a rule-consistent light distribution. An illuminated section of the light distribution of a first of the semiconductor-light sources is not identical with an illuminated section of a second of the semiconductor-light sources. The first semiconductor-light source defines a first construction type and the second semiconductor-light source defines a second construction type. The first construction type defines higher luminous flux and lower efficiency relative to luminous flux and efficiency defined by the second construction type.

  • Publication number: 20060002127
    Abstract: The present invention relates to a lens arrangement (7) for a motor vehicle headlight (7) or a motor vehicle light having at least one light source (5.1, 5.2, 5.3) that in the switched-on state emits light, the lens arrangement (7) including a plurality of individual lenses (7.1, 7.2, 7.3) that are arranged in the beam path of the light. In order to be able to manufacture and assemble the lens arrangement (7) as simply and as cost-effectively as possible, and so that the lens arrangement has the most reserved appearance possible, the present invention proposes that a light-emitting surface (7.4) of the lens arrangement (7) have a constant curvature. Advantageously, the curvature of the light-emitting surface (7.4) has no points of inflection. A light-receiving surface (7.5) of the lens arrangement (7) is advantageously configured such that, in combination with the light-emitting surface (7.4), specifiable projection characteristics of the individual lenses (7.1, 7.2, 7.3) result.
