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.

Footwear including an external LED-based lighting arrangement is described, where the lighting arrangement is coupled to the outer surface of the footwear and controlled to change the color appearance of the footwear as desired. The lighting arrangement may use individual LEDs, strings of LEDs, or optical fibers illuminated by LEDs. The arrangement may be directly attached to the surface of the footwear, or embedded within a covering that may be removably attached to the footwear.

There is provided a vehicular component which include an illumination device capable of favorably illuminating the periphery of a host vehicle. There is provided a vehicular component that includes an illumination device (3) installed on a roof part (30) and configured to cover a vehicle interior space from above. The illumination device (4) includes a light source unit (100) and a light emitting unit (300). The light emitting unit (300) configured to emit light by light emitted from the light source unit (100) is provided along an outer peripheral edge (31) of the roof part (30) in a top view of the vehicle (1).

A lighting system, having a base cone assembly, a base plate that mounts onto a dock pile, and an electrical system having at least one adjustable diameter lighting source. The present invention further has a tip cone mounted onto the base cone assembly. The tip cone has at least one light slot or clear section to permit light to emit there through. The tip cone and the base cone assembly are apex shaped. Extending from the tip cone is a mast bolt that secures to the base plate. The at least one adjustable diameter lighting source has at least one LED source and regulator. The at least one adjustable diameter lighting source emits radial and/or downward lighting onto the dock pile.

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.

One example embodiment is a photosensitive candle comprising: (a) a candle container comprising an opening; (b) a candle component disposed in the candle container, comprising: a candle body having a surface proximate to or substantially aligned with the opening; a wick with an exposed portion protruding out of the surface of the candle body; and an optical fiber embedded in the candle body and positioned juxtapose to the wick for transmitting flame lights of the wick, wherein the optical fiber comprises a first end proximate to the exposed portion of the wick and an opposing second end; (c) a lighting control component disposed in the candle container, comprising: a casing comprising an interior cavity; a controller and a power source disposed within the interior cavity; and a light sensor connected to the controller, comprising a photosensitive element proximate to the second end of the optical fiber to detect light transmitted therefrom; and (d) at least one light-emitting device connected to the controller. In some embodiments, the controller is configured to receive light signals associated with the flame lights of the wick from the light sensor, and control the at least one light-emitting device based on the received light signals.

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 lighting device is provided that includes a light source and an optical element. The light source emits primary light having a primary emission characteristic. The optical element has a light entry face and a light exit face. The optical element includes light guiding elements each forming part of the light entry and exit faces. The light entry faces inject the primary light into the optical element. The light guiding elements each have a boundary surface that totally internally reflects the primary light so that the light exit face emits a secondary light. The optical element reduces a divergence of the primary light such that the secondary light has a secondary emission characteristic with an emission angle (β) that is smaller than an emission angle (α) of the primary emission characteristic. The light exit face is larger than the light entry face.
