摘要： A headlamp unit based on a PBS includes a lens and a beam splitter. Viewed from a reverse light path, parallel light is refracted twice by an incident surface and an emergent surface of the lens and then converged in at least two focuses through the beam splitter. Each focus corresponds to a light path system, and the light path systems may be turned on simultaneously or separately to obtain a corresponding headlamp light pattern. Through beam combination of the PBS, two optical systems may achieve different illumination light shapes through on-off combination of light sources, and the two optical systems do not interfere with each other. The PBS obtains at least two accurate focus positions for the focuses of the lens, and an ideal light pattern may be accurately obtained. An upper beam light pattern may partially cover a lower beam light pattern.

摘要： The present disclosure relates to the field of automobile lamp technologies, and in particular, to a light source module based on a graded index lens, a lamp assembly including the light source module, and an automobile including the lamp assembly. The light source module includes a light source and a graded index lens disposed in front of the light source. Light emitted from the light source is incident to an incident surface of the graded index lens, and is emitted from an out-light surface of the graded index lens after being refracted and converged by using the graded index lens. The graded index lens converges the light emitted from the light source, so that the light has relatively large optical radioactive energy and a relatively small divergence angle on the out-light surface of the graded index lens.

摘要： Disclosed are PBS-based ADB function adjustment method and an intelligent vehicle light module therefor. A light source system and a light control element constitute an intelligent illumination light control system. One part of light rays emitted by the intelligent illumination light control system penetrate through a PBS to form an illumination light shape, and the other part of the light rays emitted by the intelligent illumination light control system are reflected by the PBS in a direction opposite to a photosensitive chip integrated circuit. Ambient light enters an imaging lens group in a direction opposite to an illumination light path, and one part of the ambient light is reflected by the PBS to the photosensitive chip integrated circuit to form an information source for dynamic control of the light control system.

摘要： The invention relates to a combined lens at least includes a lens and a reflector. Viewed from a reflective light path, parallel light is refracted twice by an incident surface and an emergent surface of the lens, is reflected once by the reflector, and then is converged to one point, namely a focus of the combined lens. A distance between the lens and the reflector is less than a focal length of the lens. The lens may be a convex lens or a concave lens, and the reflector may be a convex mirror, a plane mirror or a concave mirror. In addition, in a traditional lens, a focus position is controlled through two optical surfaces, namely an incident surface and an emergent surface, the lens is usually thicker in the case of the same focal length, and moreover, an optical axis direction is generally a center line of the lens.

摘要： A lens for an automobile lamp, an automobile headlamp, and an automobile are disclosed. A lens (1) for an automobile lamp includes a first lens surface (11) and a second lens surface (12) opposite to the first lens surface (11). The first lens surface (11) is a curved surface or a planar surface. The second lens surface (12) includes multiple concentric circle-type annular surfaces. By means of multiple annular surfaces (13) disposed on the second lens surface (12) of the lens (1), parallel incident light that forms an angle with a horizontal direction can be separately incident on several small surfaces without affecting horizontal parallel light penetrating the lens and being focused, so that neither light reflected by the lens nor light penetrating the lens can be effectively focused.

摘要： Disclosed are an ADB function adjustment method and a vehicle light, wherein a superposed illumination light shape is formed by a periodic high-speed change of a light shape; the periodic high-speed change of the light shape may be a shape change (dynamic superposition of light shapes) or a position change or a synchronous change in shape and position; and a light source is quickly switched off in conjunction with the periodic change of the light shape to generate one or more local dark areas, thereby realizing an adaptive driving beam function.
