Definitions

  • the invention relates to a decorative lighting fixture that can be inserted into a cavity.
  • Lighting fixtures are widely used to illuminate architectural areas. Various types of lighting fixtures are used for this purpose, with halogen low-voltage lights also being used increasingly, particularly in the area of ceiling and wall lighting. Often, many individual lighting fixtures are combined in a decorative way to illuminate a large room to form a lighting fixture ensemble. The lighting fixtures are often arranged in corresponding recesses in the ceiling or wall.
  • a common disadvantage of all previously customary lighting fixtures is that repairing or simply replacing the lamp itself is very time-consuming since the lamps themselves are difficult to access.
  • the entire circuit may have to be interrupted if the repair of a single lighting fixture is required or only one lamp has to be replaced.
  • the object of the present invention is therefore to create a lighting fixture in which, in particular, simple, tool-free replacement of the lamp is possible.
  • the idea of the invention is to enable a quick lamp change by arranging the socket on the side of the lamp adjacent to the opening of the lamp housing or other cavity and by releasably attaching the socket to the lamp housing or cavity.
  • the present invention accordingly relates to a lighting fixture with a lamp, the holder of which is arranged on the side of the lamp adjacent to the opening of the cavity and the holder is detachably fastened to the cavity via a carrier element with a fastening device, the lamp being attached via the fastening device and the Carrier element can be supplied with electricity.
  • a major advantage of the lighting fixture according to the invention is that the lamp can be removed from the cavity together with the carrier element without any problems.
  • the lamp is thus easily accessible for replacement, which is particularly advantageous in the case of halogen low-voltage lamps, since the plug contacts are then easily accessible.
  • the significantly reduced outlay in maintenance, in particular in large systems and ceiling installation systems, results in a substantial saving in operating costs of a lighting system equipped with the lighting bodies according to the invention.
  • there is an electrical separation of the Carrier element from the circuit which prevents the burns which sometimes occur when the lamp is reinserted by touching the lamp which is again live.
  • the cavity in which the lighting fixture according to the invention can be used is in particular a recess in the ceiling or a wall.
  • the fastening device is preferably attached to the opening of the cavity from which the light from the lamp emerges.
  • Preferred embodiments of the lighting fixture according to the invention result from subclaims 2 to 14.
  • the carrier element is formed in one piece with a conventional lamp socket, the carrier element being equipped at both outer ends with suitable fastening devices which not only fasten the carrier element to the lamp housing or cavity, but can also produce the electrical connection.
  • the electrically connecting fastening devices are designed so that they do not pose any danger (electric shock, short circuit) when the carrier element is removed. This can be done, for example, by the fact that these are plug-in, clamp, screw, bayonet or snap-lock fastenings, in which the protruding end remains de-energized when the carrier element is separated from the lamp housing or cavity, and the receiving end, still under current standing end of the fastening device is insulated accordingly.
  • the fastening devices can be plug-in, clamp, screw, bayonet or snap locks which are electrically connected via conventional cables, and also magnets, which is a preferred embodiment of the electrically connecting fastening device according to the invention.
  • the carrier element can have two separate parts, both of which have a fastening device for fastening to the lamp housing or cavity at one end and a device for receiving the actual lamp socket at the other end.
  • the connection to the lamp socket can be, for example, a screw, via which a wireless socket for the lamp is then connected in an electrically conductive manner due to the conductive material of the metal screw.
  • the lamp holder thus connects the two separate parts of the carrier element and forms a three-part carrier element which is provided at both ends with fastening devices which can be fastened to the lamp housing or cavity.
  • the fastening devices consist of magnets, the outer ends of the carrier element on the one hand and the corresponding devices on the lamp housing or cavity on the other hand each being equipped with magnets for mutual connection.
  • the material the parts of the carrier element and the device on the lamp housing or cavity are arbitrary.
  • the carrier element itself can also be made of ferromagnetic material, as a result of which the electrical line between the contact magnet on the lamp housing or cavity on the one hand and the screw socket for connection to the wireless version of the lamp on the other hand is ensured without any further measure. It is advantageous that the carrier element of this embodiment is formed in two parts from two electrically separate parts. The two parts are connected via the lamp holder. This enables the production of both parts of the carrier element from the same ferromagnetic material without a short circuit occurring.
  • a wireless socket is provided as a socket for the lamp, which is connected to both parts of the carrier element.
  • the socket can be replaced independently of the support element, so that the maintenance effort is significantly reduced in the event of a defect.
  • the magnets provided on the lamp housing for connection to the carrier element parts can also be attached via an insulating sleeve.
  • This embodiment serves as a safety factor since current flow in the lamp housing is prevented. Accidents, for example due to a short circuit or electric shock, are thus avoided to a considerable extent.
  • the lampholder in the lighting fixture according to the invention is therefore arranged on the side of the lamp facing away from the reflector.
  • the power is supplied in a particularly suitable manner via contacts which are attached to the rear of the insulating sleeves.
  • maximum insulation of the housing is guaranteed.
  • the lighting fixture 1 has a lamp housing 4 with a reflector 11 arranged therein.
  • the housing 4 is embedded in a ceiling or a wall, for example.
  • the reflector 11 is designed as a parabolic mirror or in another way so that it bundles the light from the lamp 2 to form a light cone which emerges on the open side of the lamp housing 4.
  • the lamp 2 is arranged with the aid of a carrier element 3 in front of the lamp housing 4 in such a way that the side 12 of the carrier element 3, to which the holder 7 of the lamp 2 is fastened, faces the inside of the reflector 11.
  • the socket 7 is arranged on the side of the lamp 2, which faces the opening of the housing 4, from the the light of the lamp 2 emerges, or on the side of the lamp 2 which faces away from the reflector 11.
  • the releasable fastening devices 5, 6 between the carrier element 3 and the lamp housing 4 consist of magnets 5 on the lamp housing 4 and magnets 6 on the carrier element 3.
  • only magnets 5 on the lamp housing 4 or only magnets 6 on the carrier element 3 can also be provided be, in which case the material of the other part to be fastened must be ferromagnetic.
  • the lighting fixture 1 can also be installed without a lamp housing 4 in a cavity, e.g. in a ceiling or wall. Struts made of ferromagnetic material or magnets 5, for example, can then be provided in the cavity for holding and possible electrical connection to the carrier element 3.
  • the carrier element 3 consists of two electrically separate parts which are connected to one another via the wireless socket 7.
  • the two electrically separated parts of the carrier element 3 on one or the other side of the holder 7 are designed in the form of brackets, each of which has a screw 8 with the special, wireless holder, for example the Bender-Wirth No. 983, 873 and 913.
  • the power supply to the lamp 2 then takes place via these fastening screws 8.
  • the lamp housing 4 has, on its open side facing the carrier element 3, legs 13 which extend outwards. In this leg 13, an insulating sleeve 9 is fitted.
  • the insulating sleeve 9 serves to hold the magnets 5.
  • contact parts made of ferromagnetic material can also be arranged in the insulating sleeves 9.
  • the insulating sleeves 9 serve to receive fastening devices 5, 6 which are electrically conductive when closed. The power is supplied via power line cable 14.
  • the magnets 5 or the ferromagnetic contact elements or the fastening devices can also be simply soldered to the power line cable 14 or conventionally connected via luster terminals or the like.
  • the lamp used is a low-voltage halogen lamp. In principle, however, ordinary light bulbs can also be used, for which suitable sockets are then selected.
  • the arrangement of the lamp 2 is also not limited to the embodiment shown. If the bulb 2 is arranged with its bulb body facing away from the lamp housing 4, the provision of a reflector 11 is unnecessary.
  • the lamp housing 4 can be made of the usual materials such as metal or plastic consist.
  • materials which do not conduct the electrical current for example plastic, will be used for safety reasons.
  • decorative coatings can be provided.
  • the carrier element 3 can also be releasably fastened in another way to the lamp housing 4 or to the opening of the cavity which accommodates the lighting fixture 1, for example by means of a screw, snap lock or also simple Plug or clamp connections.
  • the material of the fastening device is arbitrary. If it consists of electrically conductive materials, there is no need for a separate power line within the fastening device. However, adequate insulation must be provided in embodiments in the normal high voltage range. In the case of electrically non-conductive materials of the fastening device, a current-conducting connection within the fastening device, which is interrupted by the loosening of the fastening device, must be provided. In the preferred use of magnets as fastening devices, ferromagnetic materials, which both conduct the electrical current and are magnetic, can also be provided.
  • the carrier element 3 or its electrically separated parts can also consist of different materials. However, the conduction of the electrical current through the ferromagnetic material of the carrier element 3 is only suitable when low voltages, such as in the case of low-voltage lamps, are present. Normally, any materials, including plastic, preferably transparent, or aluminum are selected, which are then equipped with a current supply inside.
  • the (+) pole and (-) pole of a power line cable 14 are connected to the contacts 10.
  • the current flow takes place here via fastening devices, namely via the magnets 5 and 6, part of the carrier element 3, via the screw 8, to the lamp 2.
  • the carrier element 3 is simply pulled off with one hand, so that the lamp 2 is easily accessible and the plug contacts are clearly visible, particularly in the case of halogen low-voltage lamps. This largely prevents improper insertion of the lamp. This results in a significantly reduced effort in maintenance, in particular in large systems and ceiling installation systems, which leads to a substantial saving in operating costs for a lighting system. At the same time there is an electrical disconnection, which prevents the burns which sometimes occur when the lamp is reinserted by touching the lamp which is again under current.
