Definitions

  • the invention relates to a luminaire with at least one elongated lamp arranged in a luminaire housing, a lamp luminaire spanning the lamp and closing, transparent or translucent luminaire trough with a peripheral edge, in particular claw rim, which is detachably connected to the luminaire housing via a plurality of closures.
  • a lamp known on the market has an undercut of the lamp housing, which extends over the entire length of the side edge, which undercuts the edge of the lamp trough, which acts as a claw edge, i.e. outwardly bent edge is also overlaps over the entire length.
  • a disadvantage of this lamp is considered that the lamp can be opened again only with difficulty, especially if it exceeds a certain length.
  • lights are known in which several snap locks are articulated on the light housing, which can be hung on the edge of the tub, which must have a claw edge for this purpose, and can then be folded down into a closed position.
  • a lamp with such closures can be opened more easily, these closures are complicated to manufacture on the one hand, on the other hand, the lamp housing must be provided with receptacles specially designed for these closures, into which the closures are hung or clipped.
  • the substantially vertical edge of the lamp housing has one part of the closure, usually in the form of a molded hook, and the edge of the lamp trough has the other part of the closure, so that the two parts of the closures are inserted into one another by plugging the lamp trough onto the lamp housing can be locked together.
  • the luminaire trough which generally consists of a very brittle material, for example polymethyl methacrylate, must be provided with the closure part and can therefore no longer be produced, for example, by simple thermoforming.
  • the closure parts When attaching the luminaire trough to the luminaire housing or when loosening, the closure parts are subjected to bending loads, so that there is a risk that the closure part of the luminaire trough consisting of a brittle material will be damaged. If one of these locking parts is damaged, the luminaire tray can only be insufficiently attached to the luminaire housing; in particular, the dust and splash water tightness that may be present in a fully functional luminaire is then no longer ensured.
  • the invention is therefore based on the object of providing a lamp with closures, no additional component being required for this, these being as simple as possible to use and the risk of damage to the lamp tub being small due to mechanical stresses on the closures being small.
  • the lamp housing has a circumferential standing edge and a groove lying opposite it, and in that the closures are integrally formed on the circumferential standing edge and protrude into the groove receiving the edge of the lamp trough in such a way that when the lamp trough is inserted, they follow it overlap the outside curved edge.
  • closures are integrated into the lamp housing, so that no additional components are required and the closures can be produced together with the lamp housing as an injection molded part.
  • the closures are only provided on the lamp housing, so that the lamp tray has no special components that could be excessively stressed when closing and opening the lamp.
  • the tub housing is made of a tough material, such as polycarbonate. Therefore, the closures can be deformed to a certain extent without the risk of damage.
  • a handle can be provided on the closure, which protrudes beyond the standing edge. This means that both the locking point is marked for the installer and it is easier to operate.
  • the closures are preferably provided evenly distributed over the circumference or over the side lengths of the lamp housing. As a result of this even distribution of the closures, the mechanical load on the luminaire trough is evenly distributed over its entire circumference and the edge of the luminaire trough is held evenly in the circumferential groove of the luminaire housing.
  • a sealing tape is inserted into the groove of the lamp housing.
  • the edge of the lamp trough is pressed against the sealing tape by the overlapping closures. Thanks to this seal, the luminaire can also be used as a damp room luminaire.
  • At least two further receiving devices are integrally formed on the closures or on the standing edge on the same side length of the lamp housing, into which the edge of the lamp trough can be hung when the lamp is open.
  • These receptacles can be integrated on a closure as well as molded onto the standing edge at another point, if this is desirable or necessary for reasons of stability.
  • the luminaire 10 consists of a luminaire housing 12, a transparent or translucent luminaire trough 14 which closes the luminaire housing and has a circumferential edge 16.
  • the luminaire housing 12 has a circumferential standing edge 18, 18 'and a groove 20 lying deeper in relation to this, into which a sealing strip 22 is inserted.
  • Closures 24, 24 ' are integrally formed on the standing edge 18, 18', which are formed from formations 26, 26 'of the standing edge 18, 18', locking hooks 28, 28 'formed thereon and grip tabs 30, 30'. Several of these closures 24, 24 'are evenly distributed on the two opposite side lengths of the lamp housing.
  • Luminaires are provided on the inside of the luminaire housing along the groove 20, distributed over the circumference of centering webs 32, 32 '.
  • the shape 26 of the closures 24 lying on one side length is bent in the direction of the arrow until the edge 16 is completely released.
  • the sealing strip presses the edge of the lamp tray out of the groove 20, so that the locking lug 28 cannot overlap the edge 16 again.
  • the closures 24 lying on the same long side, not shown in section, can thus be opened effortlessly one after the other.
  • a tough plastic material polycarbonate
  • the required deformation of the formation 26 shown is possible without damage
  • Luminaire tray 14 can be removed from the closures 24 '.
  • the reverse procedure can be used to close the lamp 10.
  • the lamp trough 14 is inserted into the closures 24 'on one side length of the lamp housing 12, then the lamp trough is guided to the closures 24 on the opposite side by a rotary movement in these closures 24'.
  • closing the formation 26 does not have to be bent as shown in Fig. 1b, but the edge 16 is pressed against the inclined plane 34 of the locking hook 28 and bends the formation 26 so far that the edge 16 can be inserted into the groove 20 .
  • closures 24, 24 ' also allows simultaneous, vertical insertion of the lamp tray, in which both the closures 24 and the opposing closures 24' are pressed over the inclined plane 34, 34 'of the latching hooks 28, 28' and Edge 16 can be inserted into the groove 20.
  • FIG. 2 shows a broken side view of a closure 24 by way of illustration.
  • the molded portions 26, 26 ' are integrally formed on the standing edge 18.
  • the grip nose 30 protrudes in a trapezoidal shape beyond the standing edge 18 and thus additionally identifies the closure for the user and thus the point at which a latching hook 28 (FIG. 1) projects into the groove 20 (FIG. 1).
  • Fig. 3 shows a broken plan view of a closure area in which the elongated shape of the centering webs 32 can be seen.
  • the shape 26 also protrudes laterally beyond the standing edge 18 in order to create additional space for the locking lug 28 here with almost the same material thickness.
  • the groove 20 also tapers, which on the one hand achieves an additional clamping effect for the sealing tape 22 and on the other hand creates space for an opening 36 in which a plunger core lies during the manufacture of the luminaire housing 12. This enables the closure 24 and its locking lug 28 to be shaped with simple tools and complicated slides, among other things. avoided.
  • additional receptacle 40 is integrally formed on the closures 24 ', which essentially consists of an L-shaped hook 41 directed towards the center of the lamp housing, between the leg 42 of the hook and the shape 26 'of the closure 24' a slot is formed, into which the edge 16 of the lamp tray 14 can be inserted.
  • the receiving devices 40 can also be molded onto areas of the standing edge 18 where there are no closures, since, as can be seen from FIG. 3, the standing edge at the closing points is only insignificantly thicker and therefore the position of the receiving device does not depend on the position of the closure is.
  • This receiving device 40 is used to mount the lamp trough 14 in the open state of the lamp 10 during assembly or maintenance work on the lamp 10, for example when mounting on the ceiling.
  • the edge 16 of the lamp trough 14 is inserted into the slot remaining between the L-shaped hook 41 and the formation 26 ', and then turned downwards.
  • the edge 16 engages behind the leg 42 of the receiving device 40, and depending on the weight of the lamp trough 14 and the bending stiffness of the receiving device, the latter can also be slightly bent open.
  • 5 and 6 show a broken side view of a closure for clarification with molded receiving device or a broken top view.
  • Fig. 6 it can be seen that the hook 41 is formed on the outside of the lamp housing 12 via oblique webs 44, 44 ', which emanate from the formation 26 and a slot for the formation 26 is formed by the leg 42.
  • this type of shaping creates an opening 46 in which a plunger core lies when the lamp housing 12 is manufactured. This makes it possible to shape the receiving device 40 and its leg 42, which faces towards the inside, with simple tools and complicated slides, among other things. avoided.
