  • a particularly advantageous embodiment of the fastener is that this is formed of two opposing spring arms having at one end in each case the latching lug and the inclined ramp or ramps and which are connected to each other at its other end via a connecting web. After assembly, the two locking lugs engage from both sides into the corresponding recesses of the support element, so that a secure hold of the light influencing means is ensured. At least one actuating tab can be provided on the underside of the connecting web, by which the actuation of the fastening element for releasing the latching is simplified.
  • the light-influencing means preferably have a C-shaped profile in the region of the fastening element, wherein the connecting web of the fastening element rests on the underside of the center leg. Both side legs of the light influencing means each contain a first elongated hole through which engage the locking lugs of the spring arms. As a result, a secure hold of the fastener is achieved at the same time the light influencing means.
  • the spring arms preferably also have a C-shaped structure at their end opposite the connecting web, wherein a side limb is formed by the inclined ramp or ramps and the latching lug and the further side limb are formed by an additional contact surface, which on the underside of the center limb of the light influencing means rests.
  • the contact surface preferably has a contact projection in the form of a bead.
  • the locking lugs are each provided with a front and a rear stop edge, which cooperate with the side walls of the first slots.
  • the Side legs of the light influencing means each having a second slot, in which engage at the opposite ends of the locking lugs of the spring arms arranged sliding projections, whereby the fastener is securely guided during actuation.
  • the support element is preferably an elongated beam to be fastened to a support rail of a busbar system.
  • a fastening element for attaching light influencing means to a support element of a luminaire which comprises at least one deflectable spring arm, which contains a latching nose and an inclined ramp, which is inclined relative to the longitudinal axis of the spring arm.
  • a further inclined ramp is arranged on the spring arm, which is arranged perpendicular to the longitudinal axis of the spring arm and is inclined relative to the direction in which it extends.
  • the embodiment shown in the drawing relates to a luminaire, which is to be attached to the realization of a light band to the support rails of a busbar system.
  • the invention is not limited to such busbar systems, since a simple mounting of the light influencing means is desirable even in other lights.
  • it can also be a normal ceiling or hanging lamp.
  • Figure 1 shows the basic elements of the lamp according to the invention, which is arranged in the present example on the underside of a C-shaped mounting rail 1.
  • this support rail 1 usually run the lines for power supply and possibly also for the transmission of control signals.
  • All elements of the lamp are fastened in the example shown on an elongate beam 2, which thus forms the support structure of the backbone of the lamp.
  • the beam 2 is clamped on the downwardly open side of the C-shaped mounting rail.
  • the light influencing means forming reflector 3 u.a. also fixed the sockets for the lamp.
  • the reflector 3 which is shown in a perspective view in Figure 2, has a central region 3 1 and two laterally projecting reflector wings 3 2 and 3 3 .
  • the central region 3 1 which is placed on the beam as shown in Figure 1, has a C-shaped profile, wherein the center leg rests in the mounted state on the underside of the beam 2, while the two side legs extend perpendicularly thereto upwards , In each case a first slot 4 and a second slot 5 are provided in the side legs, whose function will be explained in more detail later.
  • the Fastening element 6 has a C-shaped claw 8 on both sides.
  • the lower leg of the claw 8 is formed by a contact surface 10 which presses with the aid of a contact projection 11 against the underside of the central region 3 1 of the reflector 3.
  • the upper side leg of the claw 8 forms a latching lug 12 which engages in the recess 13 formed by the profile of the beam 2.
  • the fastening element 6 consists of two elongate spring arms 7, which have the C-shaped claw 8 at their front end and which are connected to one another at their other end via a connecting web 9.
  • two actuating tabs 14 are further arranged, through which the fastening element can be moved to release the beam-reflector connection.
  • the fastener 6 can be made only from a single punched corresponding and bent into the shape shown piece of sheet metal.
  • the side legs of the responsible for the attachment of the reflector 3 claws 8 are formed on the one hand by the aforementioned contact surfaces 10 with the beads 11 disposed therein and by the locking lugs 12.
  • a detent 12 consists of a perpendicular to the longitudinal axis of the spring arm 7 and opposite the direction inclined inclined inclined surface 15 and a support projection arranged therebelow 16.
  • This inclined surface 15 forms the above-mentioned further oblique ramp, by the automatic recession of the spring arms 7 when placing of the reflector 3 is achieved on the beam 2.
  • the support projection 16 ensures that the pressure occurring on the surface 15 during placement actually leads to a retraction of the spring arms 7 and not to a deformation of the inclined surface 15.
  • two ramps 17 are arranged next to the locking lugs 12 on the spring arms 7, which are slightly curved and formed with the longitudinal axis of the spring arm 7 an angle enclosing pieces of sheet metal. These ramps 17 are responsible for releasing the lock when removing the reflector 3.
  • opposite ends of the spring arms 7 are also two inward Slightly protruding sliding projections 18, which cause a secure guidance of the fastening element 6 during an actuation, ie a displacement relative to the reflector 3.
  • the interaction of the beam 2 with the C-shaped claws 8 of the fastener 6 for fixing the reflector 3 is shown in an enlarged view in Figure 6.
  • the detent 12 formed by the inclined surface 15 and the support projection 16 engages through the slot 4 of the reflector 3 in the recess 13 of the beam 2 a.
  • the bead 11 presses the contact surface 10 from below against the central region 3 1 of the reflector 3, whereby the desired clamping effect is achieved for attachment.
  • the function of the bead 11 is that even in the event that the lower portion of the claw 8 is slightly bent, a defined contact with the reflector 3 is achieved.
  • the fastening element is in the latching position explained in more detail with reference to FIG. 7, in which the latching lug 12 passes through the slot 4.
  • the reflector 3 can be placed with the fastener 6 on the beam 2, without requiring an operation of the fastener 6 would be necessary. If the reflector 3 placed far enough, then snaps the locking lug 12 automatically into the undercuts 13 of the beam 2, so that the desired clamping effect is achieved. As a result, the mounting of the reflector 3 on the bar 2 is made particularly simple.
  • the locking element 6 In the locking position shown in Figure 7, the locking element 6 is in a position in which both the locking lugs 12 and the inclined ramps 17 through the slots 4 shown in Figure 2 of the side legs of the central region 3 1 of the reflector 3 reach through. In the mounted state of the reflector 3, the locking lugs 12 and the inclined surfaces 17 then engage simultaneously in the undercuts of the beam 2 a. A further movement of the fastener 6 upwards is prevented by the front stop edges 19 of the locking lugs 12 come into contact against the side walls of the slots 4 and thus block further displacement.
  • the fastener is moved in the direction of arrow in the unlocking position shown in Figure 8.
  • the oblique ramps 17 cooperate with the corresponding side walls of the oblong holes 4 in such a way that the spring arms 7 are bent out so that the latching lugs 12 emerge almost completely from the oblong holes 4.
  • the second stop edge 20 comes into abutment in the unlocking position against the lower side wall of the slot 4.
  • a secure guidance of the fastener is ensured by the engaging in the slots 5 slide projections 18.
  • the fastening element according to the invention is characterized by its simple structure, which makes it possible to produce this only from a single piece of sheet metal.
