Abstract: An optical tilt measurement apparatus includes an optical tilt sensor for use in sensing a tilt angle of a flat reflective surface around a pivot axis. The optical tilt sensor includes an optical emitter arrangement for emitting at least three beams of light so that each emitted beam of light is incident on, and reflected from, the flat reflective surface to form a corresponding reflected beam of light. The optical tilt sensor also includes an image sensor having a sensor area for detecting an intensity distribution of each of the reflected beams of light and outputting one or more signals representative of the detected intensity distribution of each of the reflected beams of light. The at least three emitted beams of light are emitted along at least three corresponding different emission paths. Each emission path extends from a corresponding emission point along a different corresponding emission direction.

Abstract: In various embodiments, a vehicle lamp is provided. The vehicle lamp includes at least one semiconductor light source, at least one light emission body, and a concentrator arranged between the at least one semiconductor light source and the respective light emission body. A larger light entrance area of the concentrator is separated from the at least one semiconductor light source by a gap. The concentrator at its smaller light exit area transitions into the light emission body. The light emission body has at least one region covered with a partly transmissive layer.

Abstract: The invention relates to an optoelectronic lamp with improved omni-directionality by using a reflector cap having an opening.

Abstract: Various embodiments relates to a device for providing electromagnetic radiation having a predefined target radiation distribution. The device has a lens arrangement and a radiation arrangement for generating electromagnetic radiation to be deflected including a predefined source radiation distribution. The lens arrangement has a first and a second lens. The first lens has a first and a second boundary surfaces. The first boundary surface is concave and the second boundary surface is convex. The first boundary surface forms a first recess. The second lens has a third and a fourth boundary surfaces. The third boundary surface is concave and the fourth boundary surface is convex. The third boundary surface forms a second recess, in which at least part of the first lens is arranged. The radiation arrangement is arranged such that at least part of the electromagnetic radiation to be deflected enters the lens arrangement via the first boundary surface.
