Description

The invention relates to a surface-mounted or surface-mounted luminaire with a housing and at least one reflector accommodated therein, to which at least one LED (Light Emitting Diode) illuminant is assigned.

Such recessed or surface lights can be embedded in ceilings or walls or alternatively mounted with their housing on a wall or ceiling surface. The at least one reflector is used to effectively bundle the light of the LED bulb and to be able to radiate directionally. In particular, if the luminous means without a reflector were arranged inside the housing, a non-negligible proportion of the light emitted by the luminous means would be reflected or absorbed ineffectively on inner surfaces of the housing. However, the bundling by the reflector can lead to a radiation in a non-desired (main) radiation direction. For many applications, an adjustability of the emission direction is therefore advantageous.

It is an object of the present invention to provide a recessed or surface-mounted luminaire of the type mentioned, in which a (main) radiation direction of the at least one reflector is adjustable in a mechanically simple manner.

This object is achieved by a recessed or surface luminaire with the features of the independent claim. Advantageous embodiments and further developments are the subject of the dependent claims.

A recessed or surface light according to the invention, hereinafter abbreviated as luminaire, is characterized in that the at least one reflector is attached via an elongate support member to the housing and disposed within a space in the interior of the housing, such that the at least one reflector is pivotable by changing the shape of the support element.

The basic idea of the luminaire according to the application is thus to mount the reflector in the housing interior via an easily modifiable and simply constructed element, the named support element. The carrier element carries the reflector and the associated LED lighting means and positions it within the housing so that there is a free space in at least one direction in which the carrier element is changed in its shape, for example bent.

Another advantage of the assembly of the reflector and the LED light source on the support element is that on the support member, a derivative of the heat that produces the LED light source to the housing is possible. Advantageously, both the carrier element and the housing are made of a good heat-conducting material, in particular of aluminum. Other conceivable bearings for adjusting the orientation of the reflector such as pivot bearings, in which the reflector is mounted on rotatable pins, generally have lower thermal conductivity.

The support member may be formed, for example, as a support plate. The carrier plate is preferably connected to the housing in one end region, and the reflector with the associated LED illuminant is arranged on an opposite free end of the carrier plate. The support plate preferably has a length between the two said end regions, which is of the order of magnitude in the range of the housing dimensions of the luminaire, for example, amounts to at least 50% of a width of the housing. In this way, a support plate with a sufficient and for stability-providing material thickness can be easily bent on site to suit the direction of radiation.

In further embodiments of the luminaire, the carrier plate may be tapered in a central region with respect to its material thickness in order to facilitate bending of the carrier plate for aligning the reflector. In a further alternative embodiment, it is possible to integrate a hinge in the central region of the carrier plate in order to further simplify the alignment of the reflector and thus the setting of the emission direction. In such an embodiment, an electromotive adjustment of the emission direction is possible by an adjusting motor integrated in the lamp.

In a further advantageous embodiment of the luminaire, the housing is a profile housing which has a constant profile in a longitudinal direction. Such a housing can be cut to length from bar stock of the desired length, so that one or more reflectors can be arranged in the longitudinal direction behind one another in the housing as required. End faces of the housing are preferably closed by closure elements.

In the formed as a profile housing one or more undercut grooves are preferably formed in the longitudinal direction, in which freely positionable fastening means for the support plate (s) for the reflectors can be mounted. More preferably, the reflector is not centrally located within the housing relative to a longitudinal axis of the housing, but arranged off-center. The support plate for the reflector is then preferably secured in an opposite half of the housing housing. In this way, the reflector in one Level to be pivoted perpendicular to the longitudinal axis of the housing. Such a luminaire is suitable, for example, for use in a projecting canopy, for example for illuminating the passage that leads under the canopy or the sidewalk in front of it. By pivoting the reflector can be determined how far a beam of light generated by the lamp, extends in the direction of the walkway.

Preferably, further strips or grooves or the like are provided as mounting means in the inner and / or outer region of the housing formed by a profile. By means of this mounting means, for example, a control electronics for the LED light source can be mounted inside the housing. Corresponding profile elements as mounting means in the outer region of the housing are used directly or indirectly via, for example mounting bracket assembly of the lamp.

More preferably, the housing has mounting elements for mounting it, e.g. on or in a ceiling or wall, which provide a pivoting possibility for the housing. For example, profile elements arranged at an angle to one another (grooves, strips, etc.) may be provided so that, depending on the selection of these profile elements, an alignment of the housing during assembly can be varied. Further, for example, a pivotable mounting bracket may be provided which is pivotally mounted on the housing via one or more pivot bearings. The mounting of the mounting bracket on the housing can be done on said profile elements (grooves, strips, etc.).

Due to the possibility of swiveling the housing, the emission direction of the luminaire can additionally be varied. In combination with the possibility of adjustment of the emission direction by the carrier element, a particularly flexibly adjustable illumination is made possible.

In a further advantageous embodiment of the luminaire, the at least one reflector is formed asymmetrically, whereby an object-related illumination and illumination is possible. In contrast to symmetrical reflectors, where the light is radiated uniformly in all directions, asymmetric reflectors allow the greatest amount of emitted light to be directed to where it is needed and where it is desired.

In a further advantageous embodiment, a cover frame with a light exit window is arranged on a housing side opposite the reflector. Advantageously, the light exit window is covered by a light exit disc, which may be transparent or partially transparent or also provided with light scattering or light-guiding means in order to achieve a desired Lichtabstrahlcharakteristik. More preferably, the cover frame with the light exit window is pivotally fixed to the housing, being provided in the installed state from the outside accessible closure means to secure the cover frame in a closed position can.

Preferred applications of the luminaire described above are roofing - also and in particular curved roofing - of e.g. Platforms and in staircases of stations, department stores, parking garages and underpasses.

• 6 a side view of in 5 shown light.

1 shows in an isometric oblique representation, a first embodiment of an according to the application surface or surface, hereinafter abbreviated referred to as light. The light is in 1 shown in an installed in the ceiling position from below obliquely.

The lamp has a housing 1 on, which is cut from a bar profile material in appropriate length. The running direction of the profile material corresponds to the longitudinal direction of the lamp. The housing is preferred 1 made of aluminum. If the LED bulb 5 has a low heat dissipation, can also plastic as a material for the housing 1 to get voted.

On the two transverse sides, where the profile material of the housing 1 is cut, each is a closure element 2 used to the housing 1 to close. The closure element 2 may be, for example, a plastic injection molded part or an aluminum die-cast part. In the illustrated embodiment is on the closure elements 2 one mounting bracket each 21 fixed, with which the lamp in a (usually suspended) ceiling can be mounted.

The housing 1 is in cross-section U-shaped with a built-in state when ceiling mounted downwards open side, by a cover frame 3 is closed. This cover frame 3 has light exit cutouts 31 behind, behind which reflectors 4 with bulbs 5 are arranged. That of the bulbs 5 radiated light is bundled by the reflectors 4 through the light exit window 31 emitted in a radiation direction.

In order to connect the lamp and / or for service purposes, the cover frame 3 be unfolded. For this purpose it is pivotable on the housing 1 stored, in this case by the side in the housing 1 arranged screws 32 laterally in folded areas of the cover frame 3 to grab. Opposite on the longitudinal side is a central closure accessible from below 33 provided that the cover frame 3 secured in the closed operating position. The closure 33 For example, it can be designed as a toggle closure, which in the adjacent closure element 2 engages and can be locked or unlocked by a partial rotation, for example a quarter or half turn.

2 shows the light of the 1 again in a plan view of the (relative to a ceiling installation) underside of the lamp.

3 shows an alternative embodiment of the lamp in a plan view analogous to 2 in which only one reflector 4 with an LED bulb 5 is available. Otherwise, the luminaire differs according to 3 in its basic structure not of the in the 1 and 2 shown. In particular, the same profile material as a housing 1 used, only cut to a shorter length.

4 gives the light to the 1 and 2 and also the 3 in a sectional view again. The cut is in a plane perpendicular to the longitudinal orientation of the profile of the housing 1 educated.

In the sectional view of 4 is the profile material of the housing 1 clearly visible. In particular, profiles are visible, for example, an undercut and accessible from the outside groove 11 and two undercut and with their opening inward facing grooves 12 , The groove 11 is used for mounting the lamp.

The grooves 12 serve for fixing of a reflector 4 and the bulb 5 , These two components are according to the application on a here as a support plate 6 assembled carrier element mounted. The carrier plate 6 carries in one end the LED bulb 5 and a reflector holder 7 , where the here asymmetrically shaped reflector 4 is attached. The connection of the LED illuminant 5 on the carrier plate 6 leads to a good thermal coupling, so that from the LED bulbs 5 generated heat through the support plate 6 can be dissipated. The carrier plate is preferred 6 Made of aluminum, in turn, a good heat conduction for the dissipation of the light source 5 to ensure generated heat. The reflector holder 7 can be made of plastic, for example.

An opposite end of the carrier plate 6 is about a fastener, in this case a screw 8th , on the housing 1 attached. The screw 8th is in a groove stone, in which a thread is cut and in the groove 12 is arranged, screwed. In this way, the carrier plate 6 and thus the reflector 4 in the longitudinal direction as desired within the housing 1 moved and positioned with it.

In a middle area 61 is the carrier plate 6 slightly angled by changing the shape, so that the reflector holder 7 around a tilt angle α opposite a base of the housing 1 is tilted. Depending on the strength of the bend in the middle area 61 can the angle of inclination α be varied and so the direction of emission of the reflector 4 to be influenced. As the direction of radiation is the main direction in which a cone of light from the reflector 4 is radiated, to understand.

In alternative embodiments, the carrier plate 6 in the middle area 61 be tapered with respect to their material thickness, so that the illustrated bend can be made easier. In other alternatives, it is conceivable in the middle range 61 to arrange a preferably self-retaining hinge, so that a change in shape of the support plate 6 can be done with little effort. In such an embodiment, an electromechanical adjusting member can be used to change the emission direction electrically controlled.

In the example shown, the carrier plate 6 in the left of the two grooves 12 attached and the reflector 4 is more likely in a right half of the interior of the housing 1 , It is possible a mirror-symmetrical arrangement in which the reflector 4 is positioned in the left half of the housing and the support plate 6 in the groove 12 that are in the drawing of the 4 located in the right half of the housing, is attached.

If several reflectors 4 are provided in a lamp, such as in the 1 and 2 can be shown for each reflector 4 a separate carrier plate 6 be provided, whose width (ie their extension in the longitudinal direction of the lamp), for example in the range of the dimensions of the reflector holder 7 lies. Alternatively, it is possible to have two or more reflectors 4 and accordingly also LED bulbs 5 on a common carrier plate 6 to arrange, which is then formed correspondingly wider.

In cross-section of 4 is also the structure of the cover frame 3 recognizable. From inside is in the cover frame 3 a light exit window 34 arranged, for example, glued. The light exit window 34 closes the light exit openings 31 and prevents the ingress of dust, insects or the like. Between the light exit window 34 and the profile 1 is a preferred circumferential seal 35 arranged so that also the transition between the cover frame 3 and the housing 1 is sealed.

Next is parallel to the light exit window 34 in the middle area of the housing 1 a preferably high-gloss or mirrored cover 9 is arranged, which has a cutout, through which the reflector 4 protrudes. This cutout is preferably chosen so large that the reflector 4 by changing the shape of the support plate 6 a sufficiently large space is available. At a front end of the reflector 4 a collar which projects far outwards is provided, which projects beyond the cutout in the cover 9 so that it can be seen from the outside through the light exit disc 34 the area of the carrier plate 6 , which has a more technical appearance, is concealed.

In the 5 and 6 is another embodiment of a surface and surface mounted light shown. 5 shows the lamp in an oblique view of the frame 3 opposite rear side of the housing 1 and 6 returns the light in a side view.

Regarding its basic structure corresponds to the in the 5 and 6 shown lamp the previously shown embodiments, in particular those of 1 . 2 and 4 ,

In the example of the 5 and 6 shown lamp is supplemented by a mounting element, which pivoting of the housing 1 in the installed state permits.

The mounting element comprises an insertion angle 13 in the outside of the case 1 trained groove 11 inserted and fixed there, for example, with the help of one or more clamping screws. The insertion angle 13 is U-shaped, with a base in the groove 11 is inserted and outside the groove 11 having legs lying. On each of these legs is a pivot bearing 14 formed, the an attached mounting bracket 15 hinged stores. On the mounting bracket 15 In turn, clamping screws could also be arranged with which a set pivoting angle relative to the insertion angle 13 can be fixed. On the mounting bracket 15 are fastening means, in this case a mounting hole formed with which the mounting bracket 15 can be fixed to a wall or ceiling.

In this embodiment, the lamp is particularly suitable for mounting in a curved roof, in which an orientation of a suspended visible ceiling element of the curved roofing of a differs located behind the visible surface supporting element.

The light comes with the mounting bracket 15 attached to the supporting element, with their orientation on the pivot bearing 14 which can be adapted to the suspended visible ceiling element. In addition, as in the previously described embodiments, the emission direction of the lamp on the support plate 6 (see. 4 ).

Next is in the embodiment of 4 and 5 a cable bushing 22 visible through which a connecting cable through the closure elements 2 can be guided into the lamp. Such a cable feedthrough 22 can be attached to both fasteners 2 be present in order to loop through a power supply line for the lamp to other lights.
