An automatic fog identification method using a front camera image and a emergency fog red LED high beam system using the same are proposed. The emergency fog red LED high beam system is configured such that a red LED module is applied to a high beam light source, thus providing a clear and wide view for a driver without diffused reflection even in a foggy situation.

A lighting device for a motor vehicle includes a first light source for producing visible light and a MEMS scanner in which a single tiltable mirror is integrated. A light spot, which is generated by the lighting device at a distance from the latter, can be moved by a scanning movement of the mirror. A control apparatus is provided in the lighting device and can be used to operate the lighting device in a first mode of operation. The control apparatus is further configured to operate the lighting device in a second mode of operation. Moreover, a sensor apparatus is provided, such that in the second mode of operation, the apparatus detects as sensor data light radiation which originates from the surroundings of the motor vehicle and which is incident on the mirror. The control apparatus carries out object recognition by way of evaluation of the sensor data.

A lamp for a vehicle includes a light source unit for generating a first light; a light adjustment unit for adjusting a first light concentration for the first light to generate a second light having a second light concentration from the first light concentration; and a movable mirror unit for reflecting the second light to form an image of a predetermined shape on a road surface. A position where the image is formed on the road surface is changed depending on a position of the movable mirror unit.

An illumination apparatus that illuminates an illumination zone having a first direction and a second direction crossing the first direction is provided with a light source to emit a coherent light beam, and a diffraction optical device to diffract the coherent light beam incident from the light source. The diffraction optical device diffracts the incident coherent light beam so that a width of the illumination zone in the second direction gradually becomes wider along the first direction of the illumination zone from a nearer side to the diffraction optical device.

A light source device includes: a substrate; a light-emitting unit matrix including a plurality of light-emitting units disposed in a matrix on the substrate; and a reflective resin disposed in a region, on the substrate, including a region where the light-emitting unit matrix is disposed.

An optical device for a motor vehicle headlight for producing continuously closed light distribution. The optical device includes: light sources; collimators which are respectively associated with a light source; and a light guiding body, which has a light shaping structure and is formed from a plurality of interconnected facets. The facets respectively have an inclination to the main emission direction, wherein the spatial vector of a facet forms a horizontal and a vertical angle of inclination to the main emission direction. The inclinations of all facets are distributed such that the horizontal angles of inclination are respectively distributed around an expected value that corresponds to the maximum luminous intensity of the light distribution such that light that enters or leaves the light guiding body via facets that have horizontal and vertical angles of inclination corresponding to the expected value forms the maximum luminous intensity of the light distribution. The light shaping structure forms the light entry side and/or the light exit side of the light guiding body, wherein the facets are distributed substantially homogeneously on the light entry and/or exit sides in relation to their respective inclinations.

Multiple light sources are arranged in an array. A light guide member receives light emitted from the multiple light sources on its back face, and outputs the light thus received from its front face. The light guide member has a base portion such that its back face faces the multiple light sources and such that it extends in the array direction of the multiple light sources. Multiple back-face protrusions and multiple front-face protrusions are formed such that they protrude from the back face and the front face of the base portion. The front-face protrusion has multiple continuous faces in the circumferential direction along the front face of the base portion.
