Definitions

  • the invention relates to a lamp which has a carrying device in order to keep the lamp housing at the intended height.
  • Luminaires are known whose luminaire housings are suspended from a ceiling with pendulum rods or with ropes. Such lights have the disadvantage that the ceiling fixation specifies the suspension location of the lamp housing, and that changes in position of the lamp housing require a new installation. Furthermore, low-voltage lamps are known in which a lamp holder or a lamp housing is suspended on two current-carrying parallel wires, the housing being able to be displaced along the wires. Such safety devices in the form of live wires are not suitable for safety reasons for luminaires that are operated with mains voltage.
  • the invention has for its object to provide a lamp, the lamp housing can still be moved with the support device mounted to make changes in position.
  • the carrying device has two hollow profile rods through which the supply lines can be passed. Plug-in parts of the lamp housing protrude into the slots of these profile rods. As a result, the lamp housing is engaged at its edges with the profile rods, so that it cannot be moved transversely to the profile rods. However, displacements of the lamp housing in the longitudinal direction of the profile rods are possible.
  • the luminaire housing lies with its side edges on the profile rods and is thereby held.
  • the profile bars are preferably arranged in a straight line and parallel to each other at a fixed distance. They form rails on which the lamp housing can be attached in any position (in the longitudinal direction), it also being possible for the lamp housing to be displaced while the plug-in parts of the lamp housing are in engagement with the slots.
  • the slots are preferably arranged on the upper sides of the profile rods, while the plug-in parts protrude downward from the lamp housing. This makes it possible to place the luminaire housing on the profile rods from above, the plug-in parts engaging with the slots.
  • the plug-in parts of the housing preferably engage directly in the slots of the profile rods.
  • profile bars e.g. Provide webs or grooves with which the plug-in parts of the lamp housing engage. If the plug-in parts protrude downwards from the luminaire housing and engage in the slots, they prevent the profile rods from spreading apart, so that the luminaire housing contributes to stabilizing the profile rods.
  • Cable passage openings can be provided on the side edges of the housing, which openings coincide with the slots in the profile rods.
  • the profile bars can be installed in a room in such a way that they form a rail-like network with nodes and branches, and luminaire housings can be attached to each pair of rails.
  • the hollow profile rods also serve as cable channels for the supply lines leading to the luminaire housings.
  • the lamp according to FIGS. 1 and 2 has an elongated lamp housing 10 which contains fluorescent lamps 11.
  • the lamp housing 10 has a convexly curved top wall 12 and a convexly curved bottom wall 13, so that it essentially has the cross section of a biconvex lens.
  • a longitudinal light exit opening 14 In the bottom wall 13, above a longitudinal light exit opening 14, there is a luminaire grid 15 made of longitudinal reflectors 16 and transverse reflecting lamellae 17.
  • a light exit opening 12a can also be provided in the upper wall 12, through which part of the lamp light is emitted upwards by one to achieve indirect room lighting.
  • the upper light exit opening 13 can be closed with an opaque or a translucent cover.
  • the walls of the lamp housing 10 consist of profile parts, which are produced, for example, in the extrusion process are and have a constant cross-section over the entire length.
  • Auxiliary devices 18, such as ballasts, are accommodated in the side areas of the lamp housing.
  • head parts 20 are provided as end walls. These head parts 20 are hollow.
  • the connecting device 19 is fastened to a head part 20.
  • the support device 21 for the lamp housing 10 consists of two rigid parallel profile bars 22 which are arranged at a mutual distance.
  • Each profile rod 22 is designed as a tube which has a longitudinal slot 23 on its upper side.
  • the slot edges 24 are bent inwards (FIG. 3).
  • the lower wall 13 of the lamp housing 10 each has an inwardly directed formation 26 which is adapted to the outer contour of the profile rod 22 and which closely encloses the profile rod over part of its circumferential region.
  • a downwardly directed plug-in part 27 is formed on the lamp housing, which protrudes into the slot 23.
  • the plug parts 27 are an integral part of the profile wall of the lamp housing and they extend over the entire length, with the exception of the head parts 20.
  • the plug parts 27, which form longitudinal strips, have a closed bottom.
  • Fig. 3 shows a cross section through a profile rod 22 in the region of a head piece 20.
  • the hollow head part 20 contains a pair of resilient plug-in parts 27a, 27b which engage in the slot 23 and are bulged laterally, so that they engage under the slot edges 24 laterally.
  • the lamp housing is latched to the profile rods 22, i.e. it can only be lifted up with a certain amount of force.
  • Inside the head parts 20 there are also the cable passage openings 20a between the elastic plug-in parts 27a, 27b.
  • the profile rods 22 have a length that is greater than a multiple of the length of the lamp housing.
  • the support device 21 is installed in the room and then the luminaire housings are mounted on it at suitable points by simply being placed on the profile rods.
  • the lamp can serve as a workplace lamp, for example, with the lamp housing being installed above a workplace.
  • the carrying device 21 forms a prefabricated unit in the form of a rigid frame, the profile rods 22 being connected to one another at their end regions by cross members 30. These cross members carry fastening devices 31 for hanging the carrying device 21 from a ceiling.
  • the profile rods 22 are longer than the lamp housing 10, so that the lamp housing can be adjusted in the longitudinal direction of the profile rods.
