Definitions

  • the invention relates to a luminaire according to the preamble of claim 1.
  • a lamp of this type is a common construction with a housing pan, a housing located in the lamp socket, electrical connection and equipment for the lamp, a cover for the housing tray of translucent material and closure means for releasably securing the cover to the housing tray ,
  • a luminaire of this type has fastening means for direct or indirect attachment to a wall or a ceiling.
  • the lamp can be attached directly or in a suspended by means of ribbons, chains or cords arrangement on the ceiling.
  • Known closure means for releasably securing the cover to the housing pan pass through the cover in feedthrough holes. hereby Not only are the appearance of the luminaire and its suitability for living or office space affected, but it can also impurities such as dust, moisture, z. As water or spray in particular, get into the housing interior or at least accumulate at the feed-through joints, which is undesirable.
  • the invention has for its object to improve a lamp of the type specified in that to the outside of the disc no fasteners are available.
  • the closure means engage only on the inside of the cover on this or they are connected only on the inside of the cover with this.
  • the functional area of the closure means which is in contact with the cover is displaced or restricted to the inside of the cover, the closure means being arranged completely in the housing interior. Therefore, the parts of the closure means with the cover in the closure function are arranged in the housing interior and thus hidden from the outside and removed from view from the outside. Therefore, the visual appearance of the luminaire which is visible when looking at the outside of the cover is also improved.
  • closure means are suitable, the housing side-side closure means parts and cover-side closure means parts cooperate by magnetic force and hold each other.
  • Such closure means may form at least one magnetic holding device.
  • a magnetic holding force is therefore particularly well suited for the closure means, because they are detachable from each other by peeling off the cover, for. B. by manual attack on the cover by means of a suction head. Ie. special, externally accessible components on the cover for releasing the closure means are not required.
  • a magnetic holding device is also advantageous because it can be realized with a low height, which also a low height for the lamp can be achieved.
  • Both a magnet of the holding device and a counter-element made of ferromagnetic material may be formed in a flat design.
  • the attachment of the cover or the disc associated closure means parts is preferably carried out by gluing.
  • a preferably annular circumferential solid layer, in particular a ceramic layer on the cover or the disc, preferably prefabricate during their production.
  • a stable adhesive attachment can be achieved.
  • At least two oppositely arranged magnetic holding devices can be realized preferably at two in the housing interior opposite each other arranged device carriers that stabilize the housing pan.
  • an annular seal is disposed between the housing pan and the cover or disc, which is preferably formed by a sealing strand of elastically deformable material.
  • the sealing strip may be permanently attached to the cover or on the housing pan, z. B. by gluing or foaming.
  • the ring seal is preferably arranged on the peripheral edge of the housing pan and the cover, wherein the closure means and also preferably existing centering surrounds and thus seals and protects against contamination.
  • the ring seal also allows - seen from the inside - dust and splash water proof design of the lamp. A luminaire with this development is therefore also suitable for rooms of medical areas, in particular examination and operating rooms, in which for the purpose of cleaning or disinfecting a splashing of the lamp takes place with disinfectants.

B. by a suction head to the cover and manual pulling the magnetic closure is releasable, wherein the holding device parts are detached from each other. It does not require a direct manual attack on the closure parts 8a, 8b, but the operator can manually attack the cover 6 to release the magnetic locks.
  • the magnetic fasteners can thus be arranged invisibly in the housing interior 3 so that they are not visible on the visible side of the luminaire 1 facing the room to be illuminated are. It is also not necessary that the cover 6 associated closure part or magnetic part, the cover 6 overlaps at its edge, as is necessary in the prior art.
