An illumination device for a motor vehicle includes at least one light source and an elongated waveguide which is delimited along the length thereof by a lateral surface. The waveguide is configured to guide light from the at least one light source along a light propagation direction in a totally reflective manner, the light propagation direction corresponding to the length of the waveguide. The light of the at least one light source can be coupled into the waveguide via a coupling surface at an end face of the waveguide, and a decoupling structure is provided in the lateral surface of the waveguide for decoupling light, which exits the waveguide via an exit region of the lateral surface along the light propagation direction, thereby overriding the total reflection condition.

A problem to be solved by an embodiment of the present application is how to make the structure of a vehicle lamp more compact. According to an embodiment of the present application, an outer lens is provided, wherein the outer lens comprises: a first lens portion; and a reflecting portion, the reflecting portion being disposed on at least one side of the first lens portion, in close contact with the first lens portion, and capable of reflecting a light beam entering the first lens portion so that the light beam is propagated inside the first lens portion. Compared with the prior art, the present application has the following advantages: the structure of the outer lens is more compact, the overall volume of the vehicle lamp is smaller, and the light output is more uniform.

Disclosed are a communication device and method for a vehicle, the device including a housing, an external lens structure covering an open front region of the housing, an internal lens structure mounted in the housing and covered by the external lens structure, a liquid crystal section mounted on the internal lens structure, configured to become transparent or opaque based on whether or not power is applied thereto, and a bezel disposed behind the liquid crystal section, such that the bezel becomes visible from an exterior of the communication device upon the liquid crystal section being controlled to be transparent.

The present invention generally relates to vehicle emblems, badges, logos or design elements and in particular to a vehicle design element including a light assembly that can provide a uniform light output without the light source being viewable.

The present disclosure discloses an optical element and a light distributing module. The optical element includes an optical element body provided with a light incident surface and a light emergent surface; the optical element body is provided with a second reflective surface peripherally arranged along the light emergent surface; the second reflective surface and the light emergent surface form a cavity, and a light source is arranged in the cavity; the light incident surface is attached to a top of the light source; and along a diameter direction of the light emergent surface, the light emergent surface includes a first transparent surface, a frosted surface, and a second transparent surface, which are connected in sequence. The light distributing module includes: the above-mentioned optical element and a reflector; and along a direction away from the light emergent surface, one end of the reflector is connected with the light emergent surface.

The present invention relates to a lighting system including a primary light source producing a primary light beam in the direction of a conversion device that returns a secondary light radiation to an optical imaging system forming a projected light beam. A light sensor generates a signal corresponding to the light received by this sensor. The light includes a non-converted light part of the first primary light beam which is returned by the conversion device in the projected light beam and is reflected by an obstacle situated in the zone illustrated by said projected light beam. A control unit has modulation means generating a modulation signal for the primary light, and demodulation means for processing the signal formed by said sensor, and determines a distance between the obstacle and the lighting system.

A vehicle lamp for emitting light at various locations adjacent to a vehicle while having a simplified configuration is provided. A vehicle lamp includes a light-emitting unit that emits light to form a road surface pattern, and a movable unit on which the light-emitting unit is mounted. The light generated by the light-emitting unit enables the road surface pattern to be formed on different locations of a road surface adjacent to the vehicle as the movable unit rotates.
