  • the carrying profile part 31 of the coupling adapter 3 further comprises a post 313 extending downwards or in the direction of the sinkers 2 as a first positioning structure.
  • the blanks 2 have at their longitudinal ends in each case a half-passage 27 integrally formed as a dimple as a second positioning structure.
  • two of the half-passages 27 of the adjacent longitudinal ends form a passage which is formed corresponding to the post 313.
  • the post 313 extends each support profile part 31 through one of the passages of the boards 2.
  • the support profile part 31 has further on its underside holding elements 314, which extend downwards or in the direction of the boards 2.
  • the boards 2 are equipped with corresponding openings 25.
  • the holding elements 314 engage in the openings 25.
  • the boards 2 are held by a clamping of the holding elements 314 in the openings 25 on the support profile part 31.
  • the longitudinal ends or end faces are preferably covered. This can on the one hand be prevented that the linear lights cause damage when a person comes into contact with the inside of the front.
  • the linear lamps themselves can be protected from dirt, moisture or the like.
  • One problem that can arise with conventional covers is that individual components expand to different extents with changing internal or external temperatures. This makes it difficult to keep the end faces of the linear lights closed in all operating conditions or to ensure that the front covers hold reliable but not damage or affect the other components of the linear lights at changing temperatures.
  • linear lights can be used:
  • Example 1 is a linear lamp with a longitudinal support profile, an optic, a light source and a longitudinal cover or end cover, in which the light source and the optics are mounted on the support profile, so that the optics at least partially covers the light source in a radiation direction, the longitudinal cover a Cover plate which covers the support profile, the optics and the illuminant on a longitudinal side or end face of the linear lamp, and comprises a spring element, wherein the spring element is arranged so that it biases the cover plate with respect to the support profile, so that the cover plate in the direction of Support profile is pressed.
  • the cover plate can be connected in the longitudinal direction movable with the support profile, so that they can be moved in the longitudinal direction.
  • the cover plate is displaced outwards or in the longitudinal direction.
  • the spring element ensures that the cover plate always bears against the support profile and thus the linear light remains closed.
  • Example 2 is the linear lamp of Example 1, wherein the longitudinal cover has a pin which is fixedly connected to the cover plate and slidably extending into a pin receptacle of the support profile.
  • a plurality of pins are provided.
  • Such a construction with pin and pin holder allows a stable and longitudinally movable connection between the cover plate and support profile.
  • a plurality of preferably parallel pins can be arranged in corresponding pin receptacles of the support profile.
  • Example 3 is the linear lamp of Example 1 or 2, wherein the longitudinal cover comprises a support profile connector which is fixedly connected to the support profile, wherein the spring element acts between support profile connector and cover plate.
  • the cover plate can be moved so efficiently relative to the support profile connector and thus also to the support profile.
  • Example 4 is the linear lamp of Example 2 and 3, wherein the longitudinal cover comprises a fixedly arranged on the pin stop sleeve and the spring element comprises a movably arranged on the pin coil spring, wherein the Pin is movable relative to the support profile connector and wherein the coil spring is biased between the stop sleeve and support profile connector.
  • the longitudinal cover comprises a fixedly arranged on the pin stop sleeve and the spring element comprises a movably arranged on the pin coil spring, wherein the Pin is movable relative to the support profile connector and wherein the coil spring is biased between the stop sleeve and support profile connector.
  • Fig. 5 and Fig. 6 show an embodiment of a provided for the linear lamp 1 longitudinal cover 7 according to the above examples.
  • the longitudinal cover 7 comprises a cover plate 71, which is shaped so that it can completely cover the end faces of the linear lamp 1. Perpendicular to the cover plate 71 extend two parallel pins 72 which are fixedly connected to the cover plate 71. Adjacent to the cover plate 71 are two spacer cylinders 73, to which the pins 72 connect.
  • the cover plate 71, the spacer cylinder 73 and the pins 72 are integrally formed.
  • a connecting sleeve 74 Adjacent to the two spacer cylinders 73, a connecting sleeve 74 is in each case arranged as a carrier profile connector on the pins 72.
  • the connecting sleeves 74 each have a passage through which one of the pins 72 extends therethrough.
  • the pins 72 are so axially movable relative to the connecting sleeves 74.
  • Adjacent to the two connecting sleeves 74, a stop cylinder 75, a helical spring 76 as a spring element and a terminating sleeve 77 are respectively arranged in succession on the two pins 72.
  • the pins 72 are axially movable relative to the stop cylinders 75 and the coil springs 76.
  • the end sleeves 77 are fixedly connected to the pins 72.
  • the coil springs are each clamped between one of the end sleeves 77 and one of the stopper cylinder 75.
  • the pins 72, together with the spacer cylinders 73, the connecting sleeves 74, the stop cylinders 75, the coil springs 76 and the end sleeves 77 extend into each of the cover receptacles 44 of the support section 4.
  • the connecting sleeves 74 are fixed to the Support profile 4 is connected and the pins 72 together with the end sleeves 77 axially movable in the cover receptacles 44.
  • the coil springs 76 By compression and expansion of the coil springs 76, the pins 72 and the cover plate 71 can be moved toward and away from the support profile 4.
  • the present disclosure also includes embodiments having any combination of features that are mentioned or shown above or below various embodiments. It also comprises individual features in the figures, even if they are shown there in connection with other features and / or are not mentioned above or below. Also, the alternatives of embodiments and individual alternatives described in the figures and the description may be excluded from the subject matter of the invention or from the disclosed subject matter.
  • the disclosure includes embodiments which exclusively comprise the features described in the claims and in the exemplary embodiments as well as those which include additional other features.
