2 AT 502 121 B1

The present invention relates to luminaires, in particular recessed luminaires and recessed luminaires as downlights, with a plurality of luminaire components, which can be connected by means of a latching connection. 5 The connection of lighting components is achieved in various ways in the prior art. For tool-free connection, for example, screw, bayonet or the like are known. For example, e.g. in DE 90 15 205 U1 a radiator disclosed, the reflector and the reflector housing is connected by means of a bayonet closure. However, these types of connection presuppose that the luminaire components to be connected are at least accessible in such a way that a corresponding screwing movement can be carried out. Another way to connect lamp components without tools together are locking connections, in which an elastic element of a lamp component engages in a corresponding counterpart of another lamp component. Such lights can be assembled relatively easily, even if the lighting components are difficult to access in the mounted state. A disadvantage, however, is that such locking connections, once they are put together, can not or only very poorly be solved again. As a rule, special tools are required to reopen the locking connections. However, this requires that the locking connections are still accessible in the assembled state of the lamp. 20

Object of the present invention is to provide a locking connection for lights available, which is simple, especially without tools, in the locked state, solvable.

The object is achieved by a luminaire having at least two luminaire components, which are lockable to one another and detachable from one another, wherein in the locked state at least one elastic latching element which is fastened to the first of the two luminaire components, on a counter element which on the second the two lamp components is fixed, engages in a locking position, so that a movement of the two lamp components is blocked against each other in at least one direction, wherein for releasing the lamp components, a 30 push element on one of the lamp components relative to the elastic locking element is mounted displaceable, so that upon relocation the thrust element is the elastic locking element of the counter-element from the locking position is deflected.

In one embodiment of the present invention, the pusher element is accessible externally in the mounted state on the lamp.

In another embodiment, the thrust element in the mounted state of the lamp is not accessible from the outside. In this embodiment, the pusher element, for example, by displacement of one of the lamp components relative to the other lamp component 40 are indirectly actuated to cause a displacement of the pusher, whereby the latching element is released.

According to a preferred embodiment, at least two elastic locking elements are provided, which cooperate with a common thrust element. In this way 45, the lighting components can be connected to each other at several points, without the release of the two lighting elements is difficult.

In a preferred embodiment, the thrust element is opposite to the direction displaced in which the two lighting elements in the locking position against each other 50 are blocked. In the case of a ceiling light, for example, one light component can be inserted into the other light component from below. The locking mechanism ensures that the inserted lighting component can not fall down. The unlocking of the two lighting components is done by moving the pusher upwards. As a result, the locking element is released and the inserted lamp component can be removed down 55. 3 AT 502 121 B1

In a preferred embodiment, the elastic latching element has an inclined surface with respect to the direction of displacement of the pusher, such that a portion of the pusher slides on the inclined surface during displacement, thereby deflecting the latching element. For example, the pusher can be displaced in one direction to thereby spread out one or more latching elements in the direction perpendicular thereto or to compress inwardly. As a result of this deflection movement of the latching element, the latching element is released from the counter-element on the second luminaire component and the first luminaire component is released.

In a preferred embodiment, the locking element has at least two legs, wherein one leg rests in the locking position on the counter element and the other leg rests against the first lamp component.

In a preferred embodiment, the locking element comprises at least one spring, in particular a leaf spring made of a spring steel.

In a preferred embodiment, the counter element for the detent spring is formed by a projection on the second lamp component, wherein the projection may be in particular a circumferential on an inner or outer periphery of the lamp component projection.

In particular, it can be provided that the first lamp component relative to the second lamp component in the locking position in a direction perpendicular to the blocking direction is freely displaceable, in particular rotatable. In this way, the lighting components in the assembled state can still readjust. This embodiment is particularly advantageous for luminaires which have an asymmetric, i. not rotationally symmetric light distribution, generate. The luminaire can then be mounted first and then rotated for the desired illumination perpendicular to the optical axis of the luminaire. This embodiment is likewise advantageous for luminaires which allow a pivoting of a light exit surface formed by the reflector in the installation plane. The pivot axis can be adjusted within the plane by turning the two lamp components against each other in any orientation. By pivoting such a lamp can be set to a desired point for illumination. This embodiment is particularly suitable for spotlights, i. Luminaires with a concentrated light intensity distribution (half-beam angle less than 35 °), advantageous.

In a preferred embodiment, the lamp has a stop which limits the displacement movement of the pushing element. The stop allows the displacement movement to the extent that the elastic element is deflected so far that it can be passed safely past the mating element of the other lighting component. However, an overstretching of the elastic locking element or slipping of the thrust element of the locking element is effectively prevented.

In the aforementioned embodiment, the stop may be formed by a portion of the elastic detent element and / or by a portion of the first or luminaire component.

In one embodiment, the luminaire is designed as a recessed luminaire, wherein the first luminaire component comprises a luminaire housing and the second luminaire component comprises a mounting frame, in particular a mounting ring, which can be fixed in a section of a support, in particular an intermediate ceiling or an intermediate wall, for example in a piece of furniture is. In this type of recessed lighting is very often the problem that the fasteners for the lighting components are not accessible when installed. Due to the locking connection according to the invention, however, the luminaire housing can be easily solved by the mounting ring again, even if the lamp is accessible only from below. For example, different luminaire housings, in particular round housings, can be inserted in the same mounting ring in order to switch from a wide-beam downlight to a wallwasher or a swivel downlight, a spotlight or other lighting devices. In a further embodiment, the first luminaire component comprises a reflector assembly and the second luminaire component comprises a luminaire housing. Due to the latching connection according to the invention, the reflector assembly can be locked in the lamp housing and released again, even if the lamp housing from the outside does not provide access to the locking connection. 10

Hereinafter, preferred embodiments of the lamp according to the invention will be illustrated with reference to the accompanying drawings.

The invention is illustrated by the example of a recessed luminaire in the form of a downlight, which essentially comprises three luminaire components: a mounting ring 2, a lamp housing 4 and 45 a reflector assembly 6. The latching connection according to the invention is in this luminaire design both between the reflector assembly and the lamp housing and between realized the luminaire housing and the mounting ring.

The locking connection according to the invention between the reflector assembly 6 and the luminaire housing 4 will first be explained below with reference to FIGS. 1 to 5 c.

Figures 1 and 2 show the lamp in a state before the reflector assembly 6 is inserted into the lamp housing 4. The luminaire housing 4 is mounted by means of the mounting ring 2 in a false ceiling 8. The mounting ring 2 is inserted in a circular section of the false ceiling 8. From below is an annular flange 10 of the mounting ring 2 on 5 AT 502 121 B1

Extent of the cut in the false ceiling 8 at. From above, the mounting ring 2 is held with a plurality of retaining claws 12 (shown only in FIGS. 6 and 7). The connection between the luminaire housing and the mounting ring will be described later in connection with FIGS. 6 to 8c. 5

The reflector assembly 6 comprises an upper reflector portion 14 and a lower reflector portion 14 'which are fixedly connected together. At the upper reflector portion 14, a support 16 is fixedly mounted for attachment of the reflector assembly. The support 16 is angled on two sides, wherein in the angles on two opposite sides in each case a io locking element or spring element 18 is fixedly mounted, for example by riveting. The spring element 18 is formed as a leaf spring made of a spring steel and has two opposite legs 20 and 22. The lower leg 20 is supported against the outer periphery of a displaceable cylinder 24, while the upper leg 22 projects into a lateral section of the cylinder 24. The cylinder 24 is displaceable relative to the reflector assembly 15, wherein it is held by the lower leg 20 of the spring element 18 in position.

To mount the reflector assembly in the housing, the reflector is pushed from bottom to top in the direction A. In this case, the cylinder 24 inverts over a retaining cylinder 26, 20 which is fixedly mounted on the inner bottom surface 30 of the lamp housing. The retaining cylinder 26 has at the lower end an outwardly directed projection 28 on which engages in the assembled state of the reflector assembly of the upper leg 22 of the spring element 18. As shown in Figures 4a and 4b, during assembly, the upper leg 22 pushes past the projection 28 and engages over this. By this Rastverbin-25 fertil the reflector assembly is securely held on the retaining cylinder and thus on the lamp housing. During the entire assembly phase, the position of the displaceable cylinder 24 with respect to the reflector assembly 6 does not change.

In one aspect of the present invention, the reflector assembly can be peeled away from the luminaire housing in a very simple manner. Referring to Figure 3 and Figures 5a to 5c, the reflector assembly 6 is pushed from below for this purpose by a distance D in the lamp housing. The displaceable cylinder 24 strikes against the upper bottom surface 30 of the lamp housing 4 and is thereby displaced downwards. By the displacement of the cylinder 24, the upper leg 22 of the Federele-35 element 18 slides over a tapered outer surface 32 of the cylinder 24. By this movement, the spring element 18 is spread and the upper leg 22 releases from the projection 28. In this movement supports the lower leg 20 of the spring element 18 laterally on the displaceable cylinder 24 and holds it in position. After the upper leg 22 of the spring element 18 is released from the projection 28 (see Figure 5b), the Reflektorbaugrup-40 pe 6 can be removed down from the housing (see Figure 5c). The displaceable cylinder 24 can be pushed back to its original position. Preferably, a blocking mechanism (not shown) is provided on the lower leg 20 to limit the upward movement of the slidable cylinder 24. 45 In this way, the two lighting components, i. the reflector assembly 6 of the lamp housing 4, slightly separate from each other, wherein the displaceable cylinder 24 acts as a thrust element, which deflects the elastic locking element 18 for releasing the lock. The thrust element, i. the cylinder 24 is not accessible from the outside in this embodiment. Nevertheless, the locking connection with this thrust element can be very easily solved so because the push element is actuated by pressing the reflector assembly 6 upwards indirectly by the stop on the bottom surface 30 of the lamp housing 4.

According to the illustrated preferred embodiment, the projection 28 is provided around the entire circumference of the retaining cylinder 26. In this way, the reflector construction group 55 can be rotated arbitrarily even in the mounted state about the vertical center axis. On a 6 AT 502 121 B1

Preferred direction when inserting the reflector assembly 6 in the luminaire housing therefore need not be respected.

In the following, the connection between the 5 luminaire housing 4 and the mounting ring 2 will be described in connection with Figures 6 to 9. It is also a locking connection, which engage in a simple manner and can be solved without tools again.

FIG. 6 shows the luminaire housing 4 and the mounting ring 2 in the disassembled state. To io interlocking of the two lighting components are located on the outer circumference of the lamp * housing several, preferably three, spring elements 118 (in the figures, only one is shown in cross section). The spring element 118 has an upper leg with a barb 120, which engages in a projection 121 on the lamp housing. The spring element 118 is pressed in the region of the upper leg by a retaining lug 140 from outside to inside in the direction 15 to the projection 121. In this way, the spring element 118 is held on the outer periphery of the lamp housing 4 and on the projection 121. In the middle region of the spring element 118, a barb 122 is provided, which protrudes from the lamp housing to the outside. 20 For mounting the lamp housing 4, this is inserted from below into the already installed mounting ring 2. The barb 122 of the spring element 118 slides past an inwardly projecting projection 128 of the mounting ring 2. Above the projection 128 of the barb jumps outwards and engages over the projection 128 a. As a result, a movement of the lamp housing with respect to the mounting ring down to Lichtaustrittssei-25 te the light is blocked. In this position is also a stop 142, in the form of one or more projections on the outer periphery of the lamp housing, from below to the projection 128 of the mounting ring 2 (see Figure 3). In this way, the movement of the lamp housing with respect to the mounting ring is blocked upwards. The luminaire housing is thus blocked with respect to the mounting ring both upwards and downwards. 30

To release the latching connection, a pressure ring 124 is provided. The pressure ring 124 is arranged on the lamp housing 4 and hooked with a hook 144 in a section of the spring element 118. To release the latching connection, the pressure ring, as shown in Figure 8b, displaced upwards against the spring element 118. In this case, a beveled edge 35 of the pressure ring 132 slides upwards on the lower part of the spring element 118 and presses it inwards in the direction of the luminaire housing. When the spring element 118 is compressed, the barb 122 is entrained inwardly and is moved away from the projection 128 (see FIG. 8b). The pressure ring can be displaced so far up until the barb 122 rests on the top of the pressure ring. In this state of the spring element, the latching between the luminaire housing and the mounting ring is canceled and the luminaire housing can be removed downwards (see FIG. 8c).

In this embodiment of the latching connection therefore the pressure ring acts as a thrust element, which causes a displacement 45 of the spring element 118 by its displacement relative to the lamp housing in order to solve the Verrasterung between the lamp housing and the mounting ring. In this way, the locking connection can be easily solved without direct access to the spring element would be necessary. In contrast to the detent connection described in connection with FIGS. 1 to 5c, the push element, namely the pressure ring, is directly actuated in this case. Such a construction is so advantageous in the cases in which the two lamp components are to be blocked in the latched state in two directions against each other, as is the case with the lamp housing relative to the mounting ring.

The projection 128 on the mounting ring 2 is provided around the entire inner circumference of the mounting ring 55. To evenly support the luminaire housing, there are a total of three

Claims (16)

Spring elements 118 are provided, wherein, depending on the intended use, four or more spring elements can be provided in order to enable a uniform fastening of the luminaire housing in the mounting ring. 5 In the mounted state of the lamp housing, the barbs 122 can be moved on the projection 128 over the entire circumference of the mounting ring. In this way, the lamp housing can be freely rotated in the mounting ring in the locked state about the vertical center axis. io Due to the free rotation of the lamp housing relative to the mounting ring in the mounted state of the lamp housing, the lighting in an asymmetric radiation or lighting application, which can be pivoted in an axis parallel to the mounting plane, can be set arbitrarily. The skilled artisan will appreciate that the simple connection system between the luminaire housing and mounting ring also different luminaire housing can be used in the same mounting ring.
