摘要： A method for producing an optical component for an illuminating device of a motor vehicle, the optical component having at least one structured surface, comprising the following method steps: generating a first virtual representation of the surface that is to be structured of the component, applying a grid of points to the virtual representation of the surface that is to be structured of the component, shifting all or a plurality of the points in a randomized manner in the positive or negative direction in parallel with the respective normals to the surface in order to structure the surface, creating a second virtual representation of the surface that reproduces the structuring achieved by the shifting of the points, and producing the component on the basis of the second virtual representation of the surface.

摘要： Disclosed is a condenser and a high-and-low-beam integrated vehicle lamp module, the condenser comprises at least one light incident portion, a light-transmitting portion, and a light emergent portion, wherein a 50L dark area light shape forming structure is formed on the light-transmitting portion; the 50L dark area light shape forming structure protrudes from a surface of the light-transmitting portion and has a slope surface; and the distance from the slope surface to the surface of the light-transmitting portion gradually increases from a position close to the light incident portion to the light emergent portion. Since the 50L dark area light shape forming structure protrudes out of the surface of the light-transmitting portion and has the slope surface, in a high-beam illumination mode, some light is emitted from the 50L dark area light shape forming structure to a 50L test point.

摘要： PROBLEM TO BE SOLVED: To provide a headlight for a vehicle attaining both forming of an integral light distribution pattern with dark spots restrained, and restraint of glare given to a person existing at the front of the vehicle.
SOLUTION: The headlight for a vehicle 10 has a partitioning member 22A fitted in free movement between a separation position and a separation release position. The partitioning member 22A, when it is at the separation position, partitions a passing area of light from a pair of light sources forming partial light distribution patterns adjacent to each other to separate the adjacent light distribution patterns. The partitioning member 22A, when it is moved to the separation release position, releases separation of the adjacent light distribution patterns. A partitioning member moving mechanism 26 makes the partitioning member move between the separation position and the separation release position. The partitioning member moving mechanism 26, when a high-beam switch is on, moves the partitioning member 22A to the separation release position, and, when an intermediate-beam switch is on, moves the partitioning member 22A to the separation position.
