Description

[0001] The invention relates to a luminaire housing comprising a box-like base body and a support for holding at least one light source designed as an LED, wherein the support is movably mounted on the base body.

[0002] The invention relates in particular to luminaire housings for fixed luminaires for domestic use, especially wall and ceiling luminaires for indoor and / or outdoor use. These luminaires usually do not have a movable support.

[0003] These types of light fixtures are usually box-shaped, with at least one open side. The fixture also has a back panel opposite the open side. This back panel allows the fixture to be mounted to a wall, ceiling, or other mounting points. The light source and its mounting bracket are located inside the fixture. When in operation, the light source emits light from the open side. Reflectors are typically integrated into the fixture to focus and / or concentrate the light for improved illumination.

[0004] In some cases, lamp housings with a movable support for operating room lamps are known, by means of which the light source can be moved for focusing in relation to a stationary reflector that is arranged on the base body of the lamp housing.

[0005] Transparent or translucent covers are known for covering the luminaire housing, for example, to protect the light source from dirt. These covers can diffuse the light from the light source. In known luminaire housings, the components and wiring necessary for operating the light source are usually located between the support and the base. Maintenance of these components and wiring requires disassembly of the support or the luminaire housing. A disadvantage of known luminaires is therefore the time-consuming and labor-intensive maintenance.
