A luminaire for providing configurable static lighting or dynamically-adjustable lighting. The luminaire uses an array of focusing elements that act on light provided via a corresponding array of sources or via an edge-lit lightguide. Designs are provided for adjusting the number of distinct beams produced by the luminaire, as well as the angular width, angular profile, and pointing angle of the beams. Designs are also provided for systems utilizing the adjustable luminaires in various applications.

A luminous panel includes a light-emitting board having a light-emitting face to form a surface of a wall device, and a receiving part to be fastened to a framing of the wall device. The light-emitting board is removably attachable to the receiving part. In the installed configuration, the emitting face forms a part of the surface of the wall device and the receiving part is at the rear of the surface of the wall device. The light-emitting board and the receiving part include complementary rotational members located near first ends of the light-emitting board and the receiving part, and complementary snap-fastening members located near second ends of the light-emitting board and the receiving part. In the assembled state, the receiving part is completely covered by the light-emitting board and the rotational members are housed in the volume between the light-emitting board and the receiving part.

A machine for extracorporeal blood treatment including a housing for accommodating operational components of the machine for extracorporeal blood treatment and a light-emitting unit having no diffusion disk for displaying an operating and/or therapy condition of the machine according to the principle of ambient light. The light-emitting unit is arranged in a predetermined sequence and/or with predetermined shaping on at least one portion of the housing. The light-emitting unit is a flexible light conductor having at least one end-face light coupling surface at a first end and at least one end-face light output surface at a second end or alternatively a self-luminous flat and/or flexible OLED unit.

A light emitting device which inactivates microorganisms is disclosed. The light emitting device may include a flexible light emitting layer emitting a light; and a transparent or translucent layer over the flexible light emitting layer. The light may travel through and exit an exterior surface of the transparent or translucent layer, creating an exiting light. The exiting light exiting the transparent or translucent layer may have at least a portion thereof having a wavelength in a range of 380 to 420 nanometers, and may disinfect the exterior surface of the transparent or translucent layer. The light emitting device may be used alone to create a self-disinfecting high touch surface, e.g., on a door, or may be shaped to mate with other structure to create a disinfecting high touch surface.

Provided are an optical member capable of implementing optical images having desired shapes through a pattern design, and a lighting device using the optical member, the optical member including: a base substrate; multiple patterns sequentially arranged on a first surface of the base substrate and having inclined surfaces with an inclination angle with respect to the first surfaces; and a reflective portion on the base substrate or the multiple patterns, wherein the multiple patterns implement a line shaped beam of a first path crossing at right angles to respective pattern extension directions of the multiple patterns by guiding a first incident beam into a first surface direction toward which the first surface looks or a second surface direction toward which a second surface of the base substrate opposite to the first surface looks, through refraction or reflection from the inclined surfaces.

A light device includes a transparent substrate having a first surface and a second opposite surface, an array of light-modifying elements formed on the substrate, and a light source to project light along a thickness direction of the substrate. The light-modifying elements having surfaces inclined at an angle with respect to at least one of the first surface and the second surface, and configured to diffuse light by reflecting and/or refracting incident light.

A light emitting device with a rotating form thereon, said device having a motor and a power source contained within a generally durable housing having a lens and an elongated spire extending outside of the durable housing and through an opening contained within the lens, said elongated spire additionally having a decorative rotatable form positioned on a distal end of the elongated spire, and at least one light source directing emitted light at the rotatable form, such that crisp hard shadows are produced on outlying surfaces. A power source is provided, connected to a motor and processor so as to move or rotate the spire and thus the form, causing the lights to cast moving decorative shadows on an exterior surface.

A solid state lighting system includes a number of light sources with multiple light colors that can be used to replace fluorescent lamps.

The present disclosure provides decorative lights using prismatic film such as Optical Lighting Film (OLF) available from 3M Company, and a diffuse partial reflector. The decorative lights generate design styles and comfort for a light fixture, and can use solid state lighting such as Light Emitting Diodes (LEDs) to generate the light. The decorative lights can have an appearance that changes with the viewing angle of the light.

A task light that includes a plurality of light emitting diodes (LED's) adapted for providing a variable intensity of emitted light; a light directing member for directing light from the LED's onto a work surface; a control logic, electrically connected to a light intensity selector, an ambient light sensor, and the plurality of LED's and wherein the control logic compares the intensity of ambient light in the area surrounding the work surface with the desired intensity of light to be provided at the work surface and adjusts the supply of electrical power to the LED's so that the total of the variable intensity of emitted light and the intensity of ambient light in the area surrounding the work surface is approximately equal to the desired intensity of light to be provided at the work surface.
