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： A vehicle lamp includes a first lamp unit for forming a first region of a beam pattern, and a second lamp unit for forming a second region of the beam pattern. The first lamp unit and the second lamp unit are arranged in a left-right direction. Each of the first lamp unit and the second lamp unit includes a plurality of lamp modules arranged in the left-right direction, each of the plurality of lamp modules including a light source unit including a light source and a light path adjusting unit. A position of light irradiation region formed by the light emitted from each of the plurality of lamp modules is particularly configured depending on a position of the light source with respect to a rear focal point of the light path adjusting unit.

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： A method for correcting a light pattern provided by an automotive lighting device, wherein the light pattern is provided at least by a matrix arrangement of light sources. The method includes a first step of projecting a high beam pattern with a first zone where luminous intensity is lower, the first zone having a rectangular edge with four sides. The second step includes providing a number of pixels for each of the four sides of the edge of the first zone, thus creating an upper blur zone, a lower blur zone, a left blur zone and a right blur zone. A final step includes creating a blur pattern for the upper blur zone which extends along columns, a blur pattern for the lower blur zone which extends along columns, a blur pattern for the left blur zone which extends along rows and a blur pattern for the right blur zone which extend along rows, where the luminous intensity in each row or column adapts from the luminous intensity of the first zone to the luminous intensity of the high beam pattern. An automotive lighting device configured to perform these steps is also provided.
