摘要： Disclosed are a projection unit for a low beam light of a vehicle, and a vehicle lamp. The projection unit is composed of a light source, a reflection plate and an optical lens. Wherein the reflection plate is provided with a reflection boundary corresponding to the shape of a bright and dark cut-off line required by an illumination light shape of a vehicle lamp system, and the reflection plate is a plane reflector, a curved reflector, or a reflector formed by connecting multiple curved surfaces. The reflection boundary is arranged near a focus of the optical lens, the light source illuminates the reflection plate, and light rays reflected by the reflection plate form an initial illumination light shape.

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.

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： Disclosed are a lens unit, an optical lens, an illumination module, a vehicle light, and a vehicle. The lens unit comprises a light incident portion (1) having first unidirectional collimation and a light emergent portion (2) having second unidirectional collimation, so as to form an asymmetric light shape. The lens unit can meet the requirement of the anisotropy of the illumination light shape of the vehicle light so as to form the asymmetric light shape, thereby meeting the requirement for a narrow and long model.

摘要： An optical lens, including a light incident portion and a light emergent portion, wherein a first single-directional alignment surface (1) is formed on the light incident portion; a second single-directional alignment surface (2) is formed on the light emergent portion; the alignment direction of the first single-directional alignment surface (1) is perpendicular to the alignment direction of the second single-directional alignment surface (2); and the first single-directional alignment surface (1) and the second single-directional alignment surface (2) jointly form a focal point or a focusing area of the optical lens. In addition, an optical lens group, a vehicle lamp system and a vehicle are further provided. The optical lens can meet the requirement for anisotropy of the illumination light shape of the vehicle lamp, and can form an asymmetrical light shape.
