Abstract: A directional illumination device for a vehicle external light comprises an array of light sources and an imaging waveguide comprising an input surface and a reflective end. Opposed guide surfaces are arranged to guide input light from the input surface to the reflective end and back along the waveguide after reflection at the reflective end, the waveguide being arranged to extract input light as it is guided back along the waveguide after reflection and to cause the extracted light to exit through the first guide surface. The reflective end has positive optical power in the direction laterally across the waveguide and the waveguide is arranged to direct the extracted light in respective output illumination directions distributed in a lateral direction in dependence on the input positions of the light sources in the direction laterally across the waveguide. A thin, high brightness and high efficiency controllable directional vehicle headlight is provided.

Abstract: A lighting device for a vehicle contains a light module with at least one light-emitting diode and a light-emitting surface lit by the at least one light-emitting diode, from which light is emitted when the lighting device is in use. The light module has an optical component containing a converter, which is between the at least one light-emitting diode and the light-emitting surface, or forms the light-emitting surface. The lighting device is designed such that the light from the at least one light-emitting diode passes through the optical component and strikes the light-emitting surface. The converter alters the wavelength spectrum of the light passing through the optical component.

Abstract: An illumination apparatus for a motor vehicle comprises: a light source, an optical waveguide with an incident surface and a reflective region; and a hologram arranged on or in the optical waveguide. The illumination apparatus is configured such that light emitted by the light source enters the incident surface of the optical waveguide in the direction of the reflective region, is reflected by the reflective region inside the optical waveguide in the direction of the hologram and interacts with the hologram. The average distance between the light source and the incident surface is at least half as great as the average distance between the reflective region and the hologram.

Abstract: To allow light from one or one group of light sources to be used for a plurality of applications. A lens structure for a vehicle lamp includes a light transmitter and a reflective surface. The light transmitter is configured to transmit light in a predetermined horizontal direction. The reflective surface is provided at an upper portion of an end portion of the light transmitter in the predetermined horizontal direction. A direction perpendicular to the reflective surface is inclined toward a direction opposite to the predetermined horizontal direction from a direction directly downward. The reflective surface totally reflects the light travelling in the predetermined horizontal direction downward. The light transmitted from below the reflective surface in the light transmitter in the predetermined horizontal direction radiates in the predetermined horizontal direction, and the light reflected by the reflective surface illuminates a road surface.
