A closure for an apparatus comprises: a plurality of light sources; a lightguide to distribute light from the plurality of light sources, the lightguide having a first primary surface opposite a second primary surface, wherein the first primary surface has a first surface treatment, and wherein light emitted from the lightguide indicates a status of the apparatus; and a frame supporting the plurality of light sources and the lightguide for selective movement of the closure vertically or horizontally relative to the apparatus.

A optically transmissive component is configured within a light fixture to provide benefits in brightness uniformity and visual appearance with the use of a light scattering extension portion that provides light scattering of light emitted from near an input edge of a light guide or other edgelit optical element. The sequential propagation of light through both the extension portion and main portion of the optically transmissive component significantly reduces the higher brightness and uneven “hotspotting” type visual defects typically produced near the input edge of an edgelit optical system. With appearance constraints removed or reduced, edgelit light fixtures with higher output, higher efficacy, and/or simplified edgelit optical components are enabled. Embodiments include the use of the extension portion of the optically transmissive component extension to mechanically position and retain an edgelit optical element within a light fixture.

Light having high directivity and high uniformity is emitted. A light source apparatus (10) according to the present invention includes: a light emitting body group (11a) in which a plurality of light sources (11) that emit directional light are arranged on one surface; and a first visual field limiting film (12) that is provided on an optical path of the light emitted from the plurality of light sources (11), and outputs light that enters the first visual field limiting film in a first predetermined angular range by homogeneously diffusing the light within the first predetermined angular range.

A backlight assembly and a display device including the backlight assembly are provided. The backlight assembly includes a light source unit, a peep-proof layer on a light emitting side of the light source unit, a light adjustment layer on a side of the peep-proof layer distal to the light source unit, and a plurality of first microstructures between the peep-proof layer and the light adjustment layer and spaced apart from each other.

A mini-LED backlight structure and a backlight module are provided. The mini-LED backlight structure includes a backplate, a glass substrate, and reflective sheets. The glass substrate includes a line surface and a lineless surface close to a side of the backplate. Light emitting diodes and a connector are disposed on the lineless surface. Furthermore, a gap is between the backplate and the glass substrate for disposing the light emitting diodes and the connector. The connector is electrically connected to an external circuit through a conducting wire. Disposing a plurality of elements, the connector, and the light emitting diodes on a same surface of the lineless surface is unlikely affecting backlight effect and saves materials at a same time.

An electronic device includes a light source member configured to provide a first light, a color conversion member disposed on the light source member and including a first conversion material that converts the first light into a second light and a second conversion material that converts the first light into a third light, and a low-refractive index layer disposed on the light source member and disposed on at least one of upper and lower portions of the color conversion member. The low-refractive index layer includes a matrix part, a plurality of hollow inorganic particles dispersed in the matrix part, and a plurality of void parts defined by the matrix part.

A planar light source includes a light guide member having a through hole, a light source, a first light adjusting member, a second light adjusting member, and a light transmissive member. The first light adjusting member having reflectivity and transmissivity with respect to light from the light source is disposed on or above an upper face of the light source in the through hole. The second light adjusting member having reflectivity and transmissivity with respect to the light from the light source is disposed above and apart from the first light adjusting member. The first light transmissive member having a higher transmissivity with respect to the light from the light source than the transmissivities of the first and second light adjusting members is disposed between the first light adjusting member and the second light adjusting member, and between a lateral face of the light source and the light guide member.

A device and method for providing diffuse emission of light through a flat surface, which includes a flat light guide having two larger flat surfaces on opposite sides and side surfaces, wherein one of the two larger flat surfaces being a light emitting surface and the other surface being a back surface, a connector for coupling light into said flat light guide, and a diffusing layer arranged in contact with at least one of said two larger flat surfaces of said flat light guide.

An increase in the amount of recycled plastic used in a display assembly can be obtained by introducing other types of plastic material that allow increasing the recyclable content beyond 25% without significantly lowering the strength properties of the plastic. The recycled plastic materials may be assembled together with a bio-based material. One example display assembly with higher recycled plastic content while maintaining sufficient plastic strength is an assembly having an external frame having 70% recycled PC ABS mixed with 30% fresh PPS (Polyphenylene Sulfide), a diffuser optical film having 60-80% recycled PET mixed with fresh PET, and a light guide path (e.g., plate) having 70% recycled PC mixed with fresh COP (Cyclo Olefin Polymers). The stiffness strength of the display assembly may further be improved by laminating the display assembly with biodegradable adhesives and/or edge-bonded with ultrasound or laser fusion.

What is described as a multilayer body which can be illuminated by means of edge lighting and optionally also by backlighting, and which has a stone look. As well as the stone layer, layers of thermoplastic material are provided, with a translucent dark-colored layer provided on the reverse side with respect to the stone layer. The structure is a pleasing design element with day/night design not just in the configuration of building interiors and facades, but can also be used in a versatile manner in the automotive sector.
