The invention relates to a luminaire (1) having a housing which is closed by a translucent cover (11). The housing accommodates a light source and control gear (6), the light source being formed from a plurality of LEDs (8) arranged on at least one circuit board (9). According to the invention the light from the LEDs (8) is coupled into at least one light guide (7) which extends from the cover (11) towards the LEDs (8). The coupled-in light from the LEDs (8) is guided in the light guide (7) to the cover (11) and is preferably emitted diffusely.

The LED lamp has an enclosure defined by a housing and an optically transmissive exit surface. A base is connected to the enclosure. The housing is connected to the base at a proximal end and diverges as the housing extends away from the base to a distal end. The optically transmissive exit surface is connected to the distal end of the housing. A LED board is positioned transversely to a longitudinal axis of the enclosure adjacent the distal end to define a first interior space and a second interior space. A passage communicates the first interior space with the second interior space. A first aperture and a second aperture in the enclosure communicate the first interior space and the second interior space with the exterior of the lamp.

The invention provides an acoustic panel comprising a plurality of parallel-arranged elongated cavities, wherein each cavity has a first cavity wall and a second cavity wall tapering to a cavity back end and defining a cavity opening angle (Y) having a value in the range of 0°
摘要:
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.
摘要:
A lighting device comprises a heat sink, a housing mounted to and/or thermally coupled to the heat sink, a basket assembly attached to the housing, a solid state light emitter thermally coupled to the heat sink, and a baffle assembly attached to the housing. Also, a lighting device comprising a basket assembly and a baffle assembly. In some embodiments, the basket assembly comprises a first member defining a first opening, a second member, a space between the first and second members, and lenses in the opening and in the space. In some embodiments, the heat sink extends farther in a first direction in a first plane than a largest dimension of the housing in any plane which is parallel to the first plane. In some embodiments, at least one additional component (e.g., a power supply module or a junction box) is in contact with the heat sink element.
