A light guide-based high-low beam system and a vehicle lamp are provided, relating to the technical field of vehicle-lamp illumination system. The high-low beam system includes a collimating light-transmitting device and a light guide. The collimating light-transmitting device and the light guide are disposed in sequence in the direction in which beams are emitted from the light source. The light-exiting face of the light guide is a convex face so that the beams emitted from the at least one light source exit through the collimating light-transmitting device and the light guide successively, forming a light spot with parallel upper and lower beams and diffusive left and right beams. In the present solution, different light sources are combined to produce one of a low-beam broadening light pattern, a low-beam inflecting light pattern and a high-beam light pattern, and various functions such as AFS and ADB can be realized.

A vehicle lamp includes: a light source unit including one or more light sources and configured to generate light; a reflector configured to reflect at least part of the light generated by the light source unit; and a lens configured to transmit therethrough a first portion of the light that is generated by the light source unit and that is reflected by the reflector to the lens. The reflector includes: a reflective part configured to reflect, to the lens, the first portion of the light generated by the light source unit; and a non-reflective part configured not to reflect, to the lens, the light generated by the light source unit. The reflective part and the non-reflective part of the reflector are configured to selectively reflect the light generated by the light source unit towards the lens to output a light distribution pattern from the vehicle lamp.

An optical indicating device, a vehicle lamp including the optical indicating device, and a motor vehicle are provided. The optical indicating device includes: at least one light source emitting a light beam; and a patterning device arranged to form an indicating pattern when a light beam emitted from the light source is transmitted through the patterning device; the patterning device includes an patterning unit arranged to pattern the light beam, and a plurality of light deflecting portions arranged adjacent to each other are formed on a side of the patterning unit facing towards the light source or facing away from the light source.

A vehicle lamp includes a projection lens, a first light source disposed behind the projection lens and configured to emit light forming a low-beam light distribution pattern which is a predetermined light distribution pattern, a reflector configured to reflect light emitted from the first light source toward a first rear focal point of the projection lens, and a second array light source disposed behind the projection lens and having a plurality of semiconductor light emitting elements arranged in at least one row. The second array light source is configured to emit light forming an additional light distribution pattern, and the center position or maximum light intensity position of the additional light distribution pattern overlaps with the low-beam light distribution pattern on a virtual vertical screen in front of the lamp.

A lamp unit and a camera are disposed in a lamp housing including a translucent cover, and an aiming adjustment of the camera is enabled. The camera is provided with a lens hood for preventing light emitted from the lamp unit from being incident on the camera. The lens hood has a required gap with respect to the translucent cover and allows the camera to tilt.
