The invention relates to a system for projecting light beams for a vehicle, including a first device configured to generate a first beam which performs a signaling function and a second device configured to generate at least a second beam for projecting a pattern, with the first device including at least one refractive optical member for shaping the first beam and in that the second device includes at least one optical element having a controlled pattern-generating surface to deflect light rays from a light source, this generating surface having local variations arranged so as to form a predetermined pattern in the second beam.

The invention relates to a lighting device for a vehicle having at least one lighting channel for generating a holographic light function assigned to this lighting channel by lighting a holographic structure of the lighting channel. Each channel includes a lighting assembly and a coupling-in surface of a light guide body disposed along a main beam direction of the lighting assembly. The lighting device also includes a holographic structure disposed on the coupling-out surface of the light guide body. The coupling-out surface is disposed in a beam path of the coupled-in light beams, so that lighting of the coupling-out surface takes place at an angle which is greater than a critical angle of the total reflection. The invention also relates to a rear light for a vehicle and to a vehicle.

An illumination device for a motor vehicle light has a plate-like transparent light guiding body (LGB). Light sources are arranged on a narrow side of the LGB and emit light that enters the LGB and propagates therein in a first main light propagation direction (X.sub.1) to the opposite narrow side. At least some of the light rays (S1), incident on the front main surface (FMS) of the light propagating in the X.sub.1 direction are totally reflected at the FMS such that the light strikes a rear main surface (RMS), which has an exit structure. At least some of the light rays (S1) which are totally reflected at the FMS and which strike the RMS exit the LGB via the exit structure. A reflector surface, which is arranged opposite the RMS, is designed such that light rays (S1) emerging from the RMS and striking the reflector surface are deflected by the reflector surface in the direction of the LGB in a second light propagation direction (X.sub.2) and the deflected light rays (S1) pass through the RMS and the FMS and are emitted into an area in front of the illumination device to form a light distribution.

A wheeled road vehicle has a main body with a front end and a rear end and defining two opposing sides extending between the front end and the rear end. A front wheel is located toward the front end and a rear wheel is located toward the rear end. The vehicle defines a footprint in plan view, the footprint having a front end, a rear end and opposing sides extending between the front end and rear end. The vehicle has a lighting system, the lighting system including one or more light sources for defining a zone of illumination extending along at least a major portion of both sides of the footprint and around the front end of the footprint.

A vehicle lamp includes a light source unit that includes at least one light source and generates light; an optical path adjustment unit that adjusts a path of the light incident from the light source unit to allow the light to become substantially parallel with an optical axis of the optical path adjustment unit; and an optical unit that transmits at least some of the light emitted by the optical path adjustment unit to form a predetermined beam pattern. The optical unit includes a plurality of incident lenses and a plurality of exit lenses corresponding to the plurality of incident lenses. In particular, a ratio of at least one lens parameter between a first pair of incident and exit lenses is different from a ratio of the at least one lens parameter between a second pair of incident and exit lenses.

A lamp for the rear of a vehicle is disclosed with a light transmissive cover having a red first illuminated surface area and a clear second illuminated surface area. It has a first LED light emitter located directly beneath the red first area, a second LED light emitter located directly beneath the clear second area, and a third LED light emitter, also located directly beneath said clear second area. The third red LED light emitter is for emitting red light through the clear second area simultaneously with light transmitted through the red first area, whereby the first and second areas are adapted to collectively form a contiguous red illuminated surface area.

A light source comprises an array of both white and amber LEDs. One or more light pipes are disposed adjacent the array of LEDs. An optical sheet is disposed adjacent the light pipe(s) wherein light modifying elements of the optical sheet are aligned perpendicular to the array of LEDs. During DRL activation, both white and amber LEDs illuminate, altering the output from a bluish-white to a warmer tone by integrating the amber LEDs with the white ones. The turn signal function exclusively illuminates the amber LEDs. This design significantly reduces the necessary number of white LEDs for a compliant DRL function while ensuring efficiency and an aesthetically pleasing lighting assembly in a compact space.
