A light bar mounted on a steering wheel includes a holding member, a substrate, a plurality of visible light sources, a plurality of infrared light sources, and a light guiding element. The holding member includes a radiating opening. The substrate is held by the holding member in such a manner that a gap is formed between a first end in a width direction of the substrate and one of side walls of the holding member. The infrared light sources are mounted and arranged on a front surface of the substrate generally along a length direction of the substrate for emitting infrared light toward the driver. The visible light sources are mounted and arranged on a back surface of the substrate generally along the length direction of the substrate. The light guiding element is configured to deflect visible light emitted from the visible light sources toward the radiating opening.

A mixed and distributed laser illumination system includes a source unit having an internally located power supply, a laser driver and a light generator. The light generator includes a plurality of laser diodes that are communicatively linked with the laser driver. The output of each laser diode is coupled to an individual cable that terminates at a fiber combiner. A transmission cable is in communication with the fiber combiner and transmits the light from the source unit to a fiber splitter. The fiber optic splitter distributes the received light to a plurality of output cables each having an optical diffuser or a conversion element for converting infrared to ultraviolet light.

A light guide guides incident light rays and emits some of the incident light rays from a light exit surface. The light guide includes a plurality of light exit areas arranged adjacent to one another and configured to change directions of the incident light rays and emit the incident light rays from the light exit surface. Each of the light exit areas includes a plurality of light exit parts in which directions of light rays with maximum intensities out of light rays to be emitted are substantially the same. The light exit parts in each of the light exit areas are configured so that the directions of the light rays with the maximum intensities out of the light rays to be emitted from each of the light exit areas are random. Each of the light exit areas has a strip shape, and lengths of the light exit areas are random.

Systems, methods, and apparatus for fiber optic lighting panels that produce twinkling star patterns by means of a light engine and specialized optics are disclosed. In one or more embodiments, a disclosed panel for creating a lighted scene comprises a substrate comprising a first surface, a second surface spaced from the first surface, and a plurality of apertures through the first and second surfaces.

Provided is a light guide for achieving an appearance resembling a stainless-steel surface with polishing marks. A light guide (13) guides incident light rays and emits some of the incident light rays from a light exit surface (14). A plurality of light exit areas (11), configured to change the directions of the incident light rays and emit the incident light rays from the light exit surface (14), are arranged adjacent to one another. Each of the light exit areas (11) includes a plurality of light exit parts (12) in which directions of light rays with maximum intensities out of the light rays to be emitted are substantially the same. The light exit parts (12) in each of the light exit areas (11) are configured so that the directions of the light rays with the maximum intensities out of the light rays to be emitted from each of the light exit areas (11) are random. Each of the light exit areas (11) has a strip shape.

A novel lighting device is provided which projects two simultaneous yet distinct lighting effects to its surrounding areas from a central mounted and covered light source, firstly illuminating a proximate surface directly by the light source and by reflection of a cover, and secondly light is remotely provided by optically conductive materials which transmit and project light, such that the central light source projects onto proximate surface areas directly and by reflection, and light projects remotely and outwardly, carried from said source by light transmission utilizing optically conductive materials.

An illumination system for a medical technology therapy and/or diagnosis system is provided. The system includes a light source, an optical waveguide, and an optical element in the form of a diffuser element. The optical waveguide has a first end that is connectable or assignable to the light source and the diffuser element is arranged at a second end of the optical waveguide so that light from the optical waveguide is injected into the optical element. The optical element has a lateral surface covered by a reflector layer at least in a section thereof. The reflector layer includes a mirror layer. The optical element has a light-reflecting area covered by the reflector layer and a light-transmissive area that is free of the reflector layer. Thus, light injected into the optical element is reflected on the light-reflecting area and emitted from the light-transmissive area.

An illuminated indicator for a doorbell can be arranged to receive light along an optical axis (e.g., that is perpendicular to a front face of the doorbell housing) and emit the light from an output portion that defines a closed loop (e.g., that extends around the optical axis) and in a direction that is parallel to the optical axis. The illuminated indicator can include a light pipe that receives light along the optical axis and reflects the light to follow a radially outward and divergent path, e.g., that is perpendicular to the optical axis. The radially outward and divergent light can be reflected to follow a path that is parallel to the optical axis for emission at an output portion of the light pipe. The light pipe can be configured to transmit a doorbell switch activation force to other parts of the doorbell to cause actuation of the switch.
