A lighting device contains light-emitting elements and has an elongated shape. The lighting device has a housing that has reflective side walls extending in a longitudinal direction of the housing; a cavity formed between the reflective side walls; and light-emitting elements arranged at least partially along the longitudinal direction relative to each other in the cavity. An opening of the cavity forms a light-emitting area, A width of the cavity expands from the light-emitting elements towards the opening at least in sections. A reflective element covers at least a section of the opening and reflects a part of light emitted from the light-emitting elements towards the cavity and reduces a width of the light-emitting area compared to a width of the opening.

Disclosed are lighting arrangements that provide, when in operation, more uniform angular light distribution emissions into an environment. The lighting arrangements use LED light sources, a light scattering optical element and partial reflectance from a light transmissive sheet or reflective layer to produce direct and indirect illumination with improved angular light distribution and uniformity onto targeted illumination surfaces such as ceilings, walls, and floors. The present disclosure provides a solution to problems of non-uniform angular distribution of light causing visual discomfort and spatial discontinuity in output. Energy savings are achieved with high optical efficiency utilizing compact, durable, robust, and aesthetically appealing optical composites and lighting arrangements capable of providing an assortment of configurable angular light distributions.

A lighting device, preferably a LED, includes a profiled element adapted to be applied to an external structure and coupled to a transparent or translucent longitudinal portion that allows the passage of a luminous flux generated by an illuminating element, preferably a LED strip, housed within a longitudinal chamber defined inside the profiled element. The profiled element also houses, in facing relationship to the illuminating element, a reflecting element oriented to reflect the luminous flux generated by the illuminating element toward the transparent or translucent longitudinal portion of the profiled element. The longitudinal chamber housing the illuminating element is separate from a second longitudinal chamber defined inside the profiled element and housing the reflecting element.

A shelf lamp includes a lamp holder, a circuit board, a light source and a first optical element; the first optical element is arranged in the light emitting direction of the first illumination light to deflect upward at least part of the first illumination light; the connection line between the light source and the lower edge of the outer panel is the C direction, and the included angle between the C direction and the vertical downward direction is greater than 45°. The shelf lamp and the identification plate lamp can simultaneously illuminate the upper and lower side areas of the laminate, and achieve different lighting effects. When they are installed on each laminate, the goods on the laminate obtain the illumination of different angles and different effects in two directions.

A billiard table top lighting apparatus provides substantially uniform lighting across the surface of a billiard table surface. In one form, the lighting apparatus includes a frame supporting lights that are non-centrally placed such that no lights are supported above a middle portion of the billiard table surface. So configured, the frame can have an attractive profile and further mount additional items above the billiard table surface to enable a variety of other features. For example, the frame may support one or more cameras, one or more motion sensors, one or more microphones, and/or one or more computing devices to enable any of a variety of innovative features. Such features could include automatic game play recording from one or more perspectives, merged video track storage for replay, review, and analysis, automatic lighting and dimming control, control of the apparatus from any mobile device, and the like.

A lighting apparatus includes a bottom cover, a first reflective plate, a second reflective plate, a light source and a light passing cover. The bottom cover has a first wall, a second wall and a bottom plate. The first wall has a first bottom edge fixed to the bottom plate. The second wall has a second bottom edge fixed to the bottom plate. The first reflective plate has a first upper side attached to a first top edge of the first wall. The second reflective plate has a second upper side attached to a second top edge of the second wall. The light source is placed between a first lower side of the first reflective plate and a second lower side of the second reflective plate.

A lighting fixture defines a lateral direction, a transverse direction, and a vertical direction. The light fixture includes a frame and a first panel supported by the frame. The first panel includes a first edge extending between a front surface of the first panel and a rear surface of the first panel. The lighting fixture includes a second panel supported by the frame. The second panel includes a second edge extending between a front surface of the second panel and a rear surface of the second panel. The lighting fixture includes at least one light source configured to illuminate the first panel and the second panel. The lighting fixture includes a light reflector extending adjacent to the rear surface of the first panel and the rear surface of the second panel. The light reflector reflects light emitted from at least one of the first panel and the second panel.

In one example, a lighting assembly includes a housing to hold an elongated lamp and an elongated device attached to or integral with the housing and configured to, when an lamp is held in the housing, convert light from the lamp having a first irradiance that is non-uniform along a length into light having a second irradiance that is uniform along the length.

A light fixture for lighting a surface includes a housing, a plurality of light sources, and a reflector for directing light out of a window of the housing. The plurality of light sources are directed away from the window of the housing and are then not directly viewable from the exterior of the housing while providing light reflected against the reflector through the window of the housing. The light sources are connected to a substrate through which power is supplied to the light sources and through which heat energy is removed from the light sources during operation. The substrate may form a portion of the housing of the light fixture.

In an embodiment, a luminaire includes a housing with a reflector. A rail is positioned near the reflector and has a light thereon which is configured to emit light into the reflector. The light is reflected from the reflector and passes through a diffuser that can act to ensure the emitted light is desirably defuse. In an embodiment, the diffuser can be removed from the housing for service or replacement.
