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.

The present invention relates to the technical field of vehicle illumination and, in particular, relates to a vehicle lamp optical element assembly, a vehicle lamp comprising the vehicle lamp optical element assembly, and an automobile comprising the vehicle lamp. The vehicle lamp optical element assembly comprises a primary optical element assembly and a secondary optical element assembly, wherein the primary optical element assembly comprises a primary optical element and a first support for supporting the primary optical element, and the secondary optical element assembly comprises a secondary optical element and a second support for supporting the secondary optical element, wherein the first support and the second support are connected in a matching manner so as to enable the primary optical element and the secondary optical element to be relatively fixed. The primary optical element and the secondary optical element are assembled into an integral structure, such that relative positions of the primary optical element and the secondary optical element are directly determined, and direct positioning between the primary optical element and the secondary optical element is realized. The positioning precision and the mounting reliability of the primary optical element and the secondary optical element can be ensured, such that the accuracy and functional stability of a light shape of the vehicle lamp are ensured.

A vehicular light-guiding body includes: an incidence surface on which light from a light source is incident; a first reflection surface; a second reflection surface; a connecting surface that has a transmission surface which transmits a portion of the light reflected by the second reflection surface from a lower side in an up-down direction on the onboard state to a guiding body outer part, and directs the light forward in the front-rear direction; a re-incidence surface that is disposed on a front side in the front-rear direction with respect to the transmission surface and on a lower side in the up-down direction with respect to the light blocking part, and allows the light transmitted from the transmission surface to the guiding body outer part to be re-incident; and an emission surface that emits the light internally reflected by the second reflection surface, and the light incident from the re-incidence surface.

A lamp for a vehicle includes a light source configured to emit light; a light guide provided in front of the light source and into which the light is incident; and a heat dissipation unit provided in close contact with one side of the light guide. The light guide includes a first recessed region formed on a bottom surface of the light guide and having an upward recessed shape, and the heat dissipation unit is provided in close contact with the first recessed region.

The present invention relates to a vehicle lamp module comprising a lens, a shading plate with a cut-off line structure, a low beam module, and a high beam module. Light emitted by the low beam module is suitable for interception by the shading plate and then emission to the lens to form a low beam type. Light emitted by the high beam module is suitable for interception by the shading plate and then emission to the lens to form a main high beam type located above a light and shade cut-off line. The vehicle lamp module further comprises an auxiliary high beam module. Light emitted by the auxiliary high beam module is suitable for interception by the shading plate and then emission to the lens to form an auxiliary high beam type located below the light and shade cut-off. The vehicle lamp module provides high beam with more uniform brightness.

A vehicle light guide and a vehicle headlight which can improve long-distance visibility are provided. The vehicle light guide has a shape having an incident surface on which light from a light source is incident, a first reflective surface which internally reflects the light incident from the incident surface toward a front in a front-back direction in a vehicle-mounted state, a second reflective surface having a shape with an inclined portion inclined to a lower side in the front-back direction in the vehicle-mounted state across an edge side on the front in the front-back direction and internally reflecting the light reflected by the first reflective surface toward the front in the front-back direction, and an emission surface that emits the light internally reflected by the first reflective surface and the second reflective surface and emits a light distribution pattern to the front of the vehicle.

A vehicle may have lights such as headlights. The lights may emit visible and infrared light. Infrared light may be used to illuminate objects that are monitored using infrared image sensors or other infrared sensors. Visible light may be used to illuminate objects that are viewed by vehicle occupants and which may be monitored using sensors. Headlights and other lights in the vehicle may be adjustable. An adjustable light may have a light source that contains an infrared light-emitting device such as an infrared light-emitting diode and a visible light-emitting device such as a visible light-emitting diode. A reflector may reflect light from the light source towards a lens. An adjustable light-blocking device may be located between the reflector and the lens. The light-blocking device may allow infrared light to pass unimpeded while adjusting visible light passing to the lens.
