A domestic appliance has an operating element, the operating element comprising a carrier, at least one pressure sensor configured for detection of an operation of the operating element, and at least one light source. A control is configured to switch the light source on or off subject to a sensor signal coming from the pressure sensor. At least one light conductor is arranged close to the light source and is configured to conduct light from the light source to at least a side of the light conductor remote from the carrier. Provided on or close to the side of the light conductor remote from the carrier is a screen comprising at least one opaque part and at least one translucent part, which together form a symbol.

A lighting system comprises a flexible support, such as a pair of fabric or web-like strips, and a plurality of tubular light sources supported by the flexible support. The flexible support may be hung from a support structure, and the tubular light sources will hang generally parallel to one another. Each tubular light source may include a plurality of LED chips, and power supply or conversion circuitry may also be disposed in the tubular light sources. Power cabling extends to the light sources, and may be adapted to provide pass-through power to other, similar assemblies to form a modular system. The assemblies may be easily deployed and repacked for storage and movement. The system is suitable for large area lighting, particularly with panels used for theater, television, and film sets, or with displays, trade show installations, and so forth.

A light fixture includes a housing and a light emitting element. The housing includes a lower edge and is configured to be recessed within a surface. The light emitting element is supported in the housing, and the light emitting element includes a planar surface spaced apart from the lower edge of the housing.

A set of louvers adapted for use with a linear luminaire has a first wall, a second wall spaced from the first wall, and a plurality of louvers extending between the first wall and the second wall. Each of the plurality of louvers is fixed to the first wall and the second wall, and may be integrally formed with the walls, and each of the plurality of louvers is spaced from the others. First and second side portions depend from the first wall and the second wall. An internal cavity of the set of louvers is defined by bottoms of the plurality of louvers and the first and second side portions. Engaging structure is defined on inwardly-facing surfaces of the first and second side portions. Combinations including the set of louvers and a linear luminaire in which the set of louvers snaps on externally to the linear luminaire are disclosed.

A lighting assembly comprising a housing (2), a lighting system and a reflector system. The housing (2) has a longitudinal direction, a lateral direction and a height direction which are perpendicular to each other. The lighting system is installed in the housing (2) and configured to produce light and emit the light out from the housing (2), the lighting system comprising a first light source (61). The reflector system is configured for reflecting the light produced by the lighting system out from the housing (2) and comprises a first reflector (41) including a first reflector surface (411) which is a concave surface with a first radius of curvature (r1). The first reflector (41) is also provided with a second reflector surface (412) which is a concave surface with a second radius of curvature (r2) which is larger than the first radius of curvature (r1), a centre of curvature (cc2) of the second reflector surface (412) being spaced from a centre of curvature (cc1) of the first reflector surface (411). The lighting assembly is configured to be such that most of the light emitted by the lighting system out from the housing (2) passes via the reflector system.

There is a category of situations which may have previously been considered direct replacement but in fact takes on many elements of a true retrofit; namely, replacing existing LED lighting systems (which they themselves were retrofits) with different LED lighting systems that (i) overcome a deficiency or inadequacy of the existing LED lighting system retrofit, (ii) adds a functionality to the existing LED lighting system retrofit, or (iii) reestablishes functionality that would otherwise be lost with the existing LED lighting system retrofit. Discussed herein are means to provide improved glare control, horizontal beam containment, playability and control functionality for interfacing with third party controls in these so-called retrofit-of-a-retrofit, or upgrade situations.

A lighting film (1) includes a first base material (2), a plurality of lighting portions (3), and a void portion (9), and if a virtual straight line (F) that passes through a point (C), at which any one light ray of light entering the lighting portion (3) is incident on a reflective surface, and is orthogonal to a first surface (2a) of the first base material (2) marks a boundary between two spaces, a space with the light ray incident on the point (C) of the two spaces is labeled as a first space (S1), and a space without the light ray incident on the point (C) is labeled as a second space (S2), the lighting film (1) has a function of decreasing intensity of light traveling toward the second space (S2) of light emitted from the first base material (2) or the lighting portion (3).
