Abstract: The present invention in various embodiments relates to an illuminating device for a vehicle, in particular a motor vehicle, for realizing an asymmetrical light distribution. The asymmetrical light distribution has a greater illumination depth on the vehicle's side of traffic than it does on the side of oncoming traffic.

Abstract: A self-focussing spectacle as well as a method for self-focussing a spectacle are proposed. The spectacle comprises at least one spectacle lens of adjustable refracting power, and means for adjusting the refracting power of the spectacle lens as a function of a measured parameter representing a state of accommodation of a corresponding eye of a user of the spectacle. The means measure the refracting power of the eye directly.

Abstract: An illuminating device for motor vehicles has a plurality of light sources formed as semiconductor light sources, each of the semiconductor light sources emitting light of only one color and light colors emitted by different semiconductor light sources are different. The semiconductor light sources include several semiconductor light sources which emit light of a same color. The semiconductor light sources are distributed so that the lights emitted by all semiconductor light sources produce a light of a uniform color which exits the illuminating device.

Abstract: An illumination device comprises a light source, a reflector which reflects light emitted by the light source, a light disc, and a plurality of optically active elements arranged in a path of rays of the light reflected by the reflector for at least one of dispersing and deviating of the light, the optically active elements being formed as diffraction-optical elements and together forming a diffraction grating which is formed as a member which is separate from the light disc.
