Definitions

  • the present invention relates to a luminaire, in particular for illuminating goods presentation areas, with a base body which can be fastened to or in a wall is one attached to the body or attachable Lampshade and a lamp holder for a Illuminant which is held on the base body.
  • Goods display areas such as refrigerated counters, Fruit pots, store shelves, etc. are usually artificially lit.
  • the goal here is the surfaces illuminate as evenly as possible.
  • lamps of the type mentioned used with transparent lamp shades This conventional Luminaires have the disadvantage that of them one Glare does not occur, as the bulbs from the outside as a particularly bright spot or area is visible.
  • the lights have only a small light control with the result that only a small part of the Lamp luminous flux actually the area to be illuminated meets.
  • common bulbs and rotationally symmetric Reflectors are used, each one circular create a luminous surface.
  • the object of the invention is therefore to provide a luminaire of the input mentioned type so that they can be used flexibly is and even after replacing a lampshade optimal lighting is ensured.
  • the lamp holder by a substantially dimensionally stable Holder spaced from the body positioned is, and the holder has a variable length, so that the distance between the base body and the lamp socket adjustable by changing the length of the holder is.
  • the invention is therefore based on the consideration that Variable position of the lamp holder and thus the ability to create the lamp socket in dependence from the size and shape of the lampshade so too Position is that an optimal lighting effect with simultaneously low glare can be achieved.
  • the lamp holder on the body by a dimensionally stable holder positioned, the length of which is changeable is, so that the distance between the main body and the lamp holder is precisely adjustable.
  • the invention provided that the holder at least has two holder elements which are axially against each other are adjustable, and fastening means provided are to the holder elements in predetermined relative positions releasably connect with each other. So can the desired Distance between the base body and the lamp socket can be adjusted by the holder elements against each other shifted and in the desired relative position to each other be fixed.
  • the Holder elements telescopically interlock.
  • This has the advantage that in a simple way against any occurring torques stable connection of the holder elements is reached.
  • the cable package for Power supply of the lamp within the holder elements be guided so that it is protected from damage is.
  • the locking of the holder elements can at this embodiment, for example by means of clamping screws done by threaded holes in the outer Holder element are screwed in until they on the inner Holder element come into contact by clamping.
  • Another Possibility is to correspond to each other To provide through holes in the two holder elements and after setting a desired position one or more pins or bolts through the top of each other to put lying holes.
  • the Holder elements designed striving or rod-like and arranged parallel to each other with an overlap region be, whereby the mounting of the holder especially just make it easy.
  • the fastening means for releasably connecting the holder elements may suitably be in the form of clamping or plug-in means may be provided.
  • the through holes as Long holes be formed so that a very simple and at the same time very precise possibility is given the distance between the base body and lamp socket too change.
  • the adjustment can be stepless in this case done so that a subsequent fine adjustment not necessary is.
  • the passage openings can also be in the form of perforated strips be executed. Then there is the possibility after setting a desired relative position, if necessary protruding free ends, for example by Abknikken easy to shorten.
  • a fixation of Holder elements in a simple manner realized by a Pin or bolt through corresponding holes in the tape is stuck. Both holder elements can Through holes in the form of perforated strips have, but it is sufficient if one of the holder elements having only a single passage opening.
  • a clamp connection for example possible in the form of a screw connection.
  • the holder on the body by a Fix screw connection.
  • the holder can be so opposite be axially adjusted by twisting the body to make any necessary fine adjustment.
  • the main body can be cylindrical and be provided with an external thread on which the holder is screwed on.
  • the holder may be formed like a bow, in which case the axial length adjustment via the corresponding stirrup leg respectively. Due to the bow-shaped design It is particularly easy, a mounting ring on the holder to fix.
  • FIG. 1 schematically shows a suspended luminaire 1 according to FIG of the present invention having a substantially cylindrical Base 2, on which a canopy 3 fixed is. At the canopy 3, a connector is arranged, over which the light by means of a steel rope or a rod suspension 4 to an electronic supply unit 6 is suspended.
  • This Connecting cable 5 is designed as a 3-wire ignition cable and has an electrical capacity of less than ⁇ 80 pF / m, so that the connection cable 5 depending from the electrical line capacity a maximum Own length of 6 m and otherwise separate from the lamp can be positioned on a wall or ceiling.
  • the connection cable 5 is further a steel cable integrated, so that the lamp 1 also alone of the connection cable 5 can be worn. Otherwise, the Lamp socket 8 have a protective conductor terminal and / or high voltage resistant.
  • FIG. 5 shows two rod-shaped and strut-shaped holder elements 10a and 10b, each corresponding to each other Slotted holes 21 are executed.
  • the holder elements 10a, 10b can here also axially against each other be moved, where they are in a desired relative position for example by clamping by a screw connection be fixed. From the screw connection is in the Drawing the screw 11 shown, which is the two Long holes 21 passes through and on the holder elements 10a and 10b secured by a nut, not shown is. It is understood that it is basically sufficient may be in one of the two holder elements Slot to form while in the other holder element a normal bore can be provided.
  • FIG. 2 shows a second embodiment of a device according to the invention Luminaire 1, which has the same basic structure as the lamp 1 according to the figure 1 with a cylindrical Base 2, a lampshade suspended from it 7 and a lamp holder 8, which on the body 2 is fixed by a dimensionally stable holder 9, having.
  • the holder 9 does not consist of a central Strut, but is bow-shaped and has a central mounting portion 9a, which on the cylindrical base body 2 is screwed, and two of them laterally downwardly projecting stirrup legs, which are designed like struts and at their free ends carry a mounting ring 17, on which the lamp socket 8 is attached.
  • the reflector has 15 light exit openings 15a, through which light can escape into the lampshade 7.
  • the Avoiding the formation of light points is around the holder 9 around a diffuser 16 is provided, which at the Mounting ring 17 is attached and, for example, in shape a transparent screen is formed.
