The invention provides a vehicle lamp structure, which includes a first substrate, a first light-emitting element, a light guide and an optical member. The first light-emitting element is disposed on the first substrate. The light guide includes a light guide body and a light guide bump. The light guide body has an arc structure facing forward. The light guide body extends backward to form the light guide bump. The first light-emitting element is arranged below the light guide bump. The optical member is arranged in front of the light guide. The first light-emitting element upwardly emits a first light ray into the light guide bumps. After being reflected by the light guide bumps, the first light ray travels forward and emits from the arc structure. The first light ray is then received by and transmitted through the optical member.

A lamp module includes a light source unit that generates light; a light guide unit that guides the light incident on an incidence portion from the light source unit to be emitted to an emission portion; and an optical unit that transmits the light emitted from the light guide unit to allow a predetermined beam pattern to be formed. In particular, the optical unit includes a plurality of lenses disposed in a vehicle width direction, and the emission portion includes a plurality of emission surfaces disposed in the vehicle width direction to correspond to the plurality of lenses.

A light emitting diode (LED) lamp, vehicle headlight system and vehicle headlight that are adapted for use with an electrical system of a vehicle that was designed for a conventional lamp-based headlight. To adapt to the electrical system designed a conventional lamp-based headlight, a correcting circuit is utilized that allows for LEDs to be powered irrespective of a polarity of a power signal provided by the vehicle.

The present disclosure relates to vehicle lamps, and discloses a reflection-type headlamp module, comprising a light source, a light-collimating element, a reflecting element, and a lens, wherein the light-collimating element is suitable for converging light emitted by the light source and projecting the light; and the reflecting element is arranged on an emergent light path of the light-collimating element, so as to be suitable for reflecting the light emitted by the light source to the lens, and the light is projected by the lens to form an illuminating light pattern. The present disclosure further discloses a headlamp module. Besides, the present disclosure further discloses a headlamp and a vehicle using the headlamp.

When a pedestrian who is crossing a road or is about to cross a road is detected and it is determined that there is a risk of the own vehicle coming into contact with the pedestrian, a figure rendering forming optical unit provided in a housing of a head lamp emits a spot of light having a predetermined width and a predetermined length to a road surface ahead in a crossing direction including the pedestrian or the like. Accordingly, the pedestrian or the like knows the presence of an approaching vehicle and a driver knows the presence of the pedestrian or the like who is crossing a road or is about to cross a road.

A vehicle infrared lamp system mounted on a vehicle equipped with an infrared camera includes: an infrared light source; a rotating reflector; an other-vehicle position acquisition unit configured to acquire position information of another vehicle; and a control unit configured to control a lighting state of the infrared light source based on the position information of the other vehicle acquired by the other-vehicle position acquisition unit such that a dimming region where radiant intensity of infrared light is lower than radiant intensity of any other region is formed on at least a part of the other vehicle.

A high-low beam switching device includes a lamp seat mechanism, a light pattern switching unit, and a light pattern tuning mechanism. The light pattern switching unit includes a light occluding plate pivotable relative to the lamp seat mechanism between low and high beam positions. The light pattern tuning mechanism includes a blocking member, an adjusting member operable to move the blocking member forwardly and rearwardly relative to the lamp seat mechanism, thereby adjusting an angle between the light occluding plate and the blocking member when the light occluding plate is pivoted to the low beam position.
