A vehicle comprises a first lighting assembly disposed to the left of a longitudinal axis of the vehicle and comprising a first array of independently operable light emitting diodes and a first projection lens arranged to form a front left light beam for the vehicle from light output from the first array of light emitting diodes, a second lighting assembly disposed to the right of the longitudinal axis of the vehicle and comprising a second array of independently operable light emitting diodes and a second projection lens arranged to form a front right light beam for the vehicle from the second array of light emitting diodes, and a controller configured to control activation of the light emitting diodes in the first array of light emitting diodes to adjust an angle between the front left light beam and the longitudinal axis of the vehicle and to control activation of the light emitting diodes in the second array of light emitting diodes to adjust an angle between the front right light beam and the longitudinal axis of the vehicle.

Lighting assembly for vehicle

The invention describes a lighting assembly for use in a lighting arrangement of a vehicle. The lighting assembly includes a projection lens and a light source array, wherein a center of the light source array and an optical axis of the projection lens have a lateral offset, and light sources of the light source array are individually controllable to adjust a swivel angle of a light beam generated by that lighting assembly. The invention further describes a controller for controlling the light sources of such a lighting assembly. The invention also describes a lighting arrangement for a vehicle, comprising such a lighting assembly and such a controller for controlling the light sources of the lighting assembly to adjust the swivel angle of the light beam. The invention also describes a method of generating a front beam for a vehicle comprising such a lighting assembly.

The invention describes a lighting assembly (') for use in a lighting arrangement () of a vehicle (), comprising a projection lens () and an array () of light sources (S, . . . , S), wherein the projection lens () and the light source array () are arranged according to an asymmetry displacement (&#x3a6;i, &#x3a6;, di, d) of the optical axis (X, X) of the projection lens (), and wherein the light sources (S, . . . , S) of the light source array () of the lighting assembly (&#x2032;) are individually controllable to adjust a swivel angle (&#x3c3;, &#x3c3;) of a light beam (BL, BH) generated by that lighting assembly (&#x2032;). The invention further describes a controller () for controlling the light sources (S, . . . , S) of such a lighting assembly (&#x2032;). The invention also describes a lighting arrangement () for a vehicle (), comprising such a lighting assembly (&#x2032;) and such a controller () for controlling the light sources (S, . . . , S) of the lighting assembly (&#x2032;) to adjust the swivel angle (&#x3c3;&#x3c3;) of the light beam (BL, BR). The invention also describes a method of generating a front beam (B, B) for a vehicle () comprising such a lighting assembly (&#x2032;).

The invention provides a lighting device () and a luminaire (). The lighting device comprises a light emitter () thermally connected to a heat sink (). The lighting device further comprises a communication circuit () which is coupled to the heat sink for transmitting and/or receiving a communication signal. The heat sink is electrically conductive and comprising an opening () having dimensions for constituting an aperture antenna () for a particular frequency for directionally transmitting and/or receiving the communication signal of the particular frequency via the heat sink. In the embodiment shown, the lighting device comprises an aperture antenna () and a further aperture antenna ().

Lighting device and luminaire comprising an integrated antenna

A lighting system is disclosed which includes a light source unit and a projection system for producing a desired light distribution pattern in a target area, especially for use in an automotive head lighting, studio and theater lighting, indoor spots with adjustable beam width or direction, architectural dynamic lighting, disco lighting and other. The lighting system is especially suitable for a light source unit having one or more Lambertian light sources, especially a plurality of LEDs. For generating a desired light distribution pattern in the target area, the light source unit may include a plurality of collimators that are configured especially such that the curved focal plane (P) of the projection system intersects with or tangentially touches the exit apertures of the collimators.
