Description

Luminaire, in particular wall and / or ceiling light

The invention relates to a luminaire having the features of the preamble of claim 1. Such luminaires are used in a variety of premises, for example in office or business premises, in sales rooms, in living spaces and everywhere where good lighting is important.

Known luminaires of this type have a housing in which one or more fluorescent tubes are mounted. These fluorescent tubes consume comparatively much energy, which is becoming less and less desirable today. In addition, these fluorescent tubes can flicker, which is very unpleasant for the people in the room. If several such lights are to be mounted, they must be aligned with each other.

DE 10 2008 036 474 AI describes a lighting system for luminaires, which use LED bulbs. The light source is arranged in a rail which has a plurality of openings on one side. Here, either an opening for each LED is provided or an opening for each LED associated with a light-guiding element. Lens or reflectors are proposed as light-guiding elements, the light emitted by each LED being directed by its own lens or reflector. A disadvantage of this arrangement, however, is that a plurality of openings must be provided for the LEDs and that additionally the individual light-guiding elements such as lenses or reflectors must be provided. If a different number of LEDs are to be used in the same rail, this is not easy to enable. The document DE 20 2008 017 219 Ul describes a light emitting diode light unit. Several LED lamps are arranged on a substrate. In addition, a Lichtfokussierplatte is provided which focuses the emitted light from the LEDs and then emits. In addition, a translucent cover is provided, which is arranged below the Lichtfokussierplatte. This additional component makes the device thus described more expensive, which should be avoided.

The object of the invention is therefore to avoid the aforementioned disadvantages and to provide a luminaire, which is inexpensive and easy to manufacture and yet energy-saving operable, does not flicker and ensures good illumination of the rooms. This object is solved by the characterizing features of claim 1, which have the following special significance.

The light emitting device comprises a plurality of LEDs (light emitting diodes). In particular, the use of ten LEDs per light-emitting device has proven itself. But it can also be provided a different number of LEDs. These LEDs consume significantly less energy than conventional fluorescent tubes. In addition, such LEDs can also work flicker-free. For this purpose, the rail has on one side along its longitudinal axis an opening through which the light emitted by the LEDs can emerge. This opening is closed by a translucent prismatic disk, which has a honeycomb-shaped profile. This has the advantage that the light emitted by the LEDs light can be well distributed, so that the space to be illuminated is uniformly and well illuminated. Persons looking at the luminaire in operation will not be blinded by the LEDs. By using the prismatic wafer with honeycomb profile, the LEDs are not visible as individual points of light, but as distributed over the surface of the prismatic lens illumination. In addition, by the arrangement and the honeycomb shape of the prismatic lens, the angle at which the light is emitted from the lamp can be determined. This is important in particular to comply with ergonomic and employment regulations and to ensure a good illumination of the room. The LEDs can be adjusted so that they produce different colors, especially different shades of white. The luminaire according to the invention achieves illumination with constant brightness and color quality with lower power consumption and thus lower energy consumption, which is furthermore inexpensive to manufacture.

Particularly preferably, the rail comprises an aluminum profile or consists of such. Such aluminum profiles are easy to manufacture. It can be provided different forms of aluminum profiles.

In addition, aluminum is a very light material. Aluminum has the necessary temperature resistance, is less susceptible to corrosion and corrosion

Wear and has a high thermal conductivity factor to dissipate the waste heat produced by the LEDs. In addition, such are

Aluminum profiles even after their lifetime simply the

To recycle.

Advantageously, the LEDs can be arranged on a board, which is fixedly attachable to the rail in the interior. The board can provide the supply of LEDs with electrical energy, and possibly an electronics for control or other electrical lines. Between the circuit board and the rail, in a particularly preferred embodiment, a heat conducting means, ie a means with high thermal conductivity, such as a thermal paste or heat conducting foil, are provided. This serves to dissipate the heat caused by the LEDs to the housing. This will prevent the LEDs from overheating, becoming damaged, or shortening their life. In a particular embodiment, the lamps themselves can be arranged in a housing, in particular in apertures of a housing. Depending on the size and shape of the housing, the luminaire designed in this way can serve as a grid lamp. Is the case in a size of 625 mm x 625 mm or 600 mm x 600 mm, the luminaire can serve as a standard recessed luminaire. It has proven useful to provide the already mentioned ten LEDs per rail. These provide sufficient brightness and otherwise meet the requirements of such grid lights. Of course, this type of light is also advantageous for other forms of ceiling lights and wall lights. The electronics used to control the LEDs can then also be accommodated in the housing.

The luminaires with housing according to the invention can also be designed as suspension lights, underfloor lights or surface mounted lights. To then align the ceiling light in the desired distance to the ceiling of the room, one or more slides may be provided, which make the ceiling lamp with respect to the ceiling of the room adjustable in height. In particular, it is advantageous to fix the carriages in the desired position by means of fixing means, such as screws.

In order that as much of the light emitted by the LEDs is radiated into the room, the rail is formed on its inside in a particularly preferred embodiment, at least partially reflective. This can also be done by introducing mirrors on the inside of the rail. Thus, the light emitted by the LEDs is reflected and emitted into the room. With a few LEDs, enough light is generated to illuminate the room. If the rail comprises an aluminum profile, the inside of the profile can be designed to be reflective so that it serves as an additional reflector for the light emitted by the LEDs. The use of an additional mirror is then not required. Nevertheless, the light emitted by the LEDs is sufficiently used. The electronics required for operating the light-emitting device or devices is preferably arranged in the rail, in particular at one of its ends. This is easier for mounting and electrical connection. However, it is also possible to have an extra space inside the Provide rail in which the electronics is or in which they can be arranged.

In a particularly preferred embodiment, the ends of the rails are formed so that a plurality of rails can be plugged one behind the other, thereby establishing an electrical contact between the respective ends of the rails. Preferably, for this purpose, plugs are provided at the ends of the rails, for example male and female plugs, which can be plugged into one another. Since these connectors are electrically effective contact, it is then possible to provide a Stormzuführung only on a single rail, in which case the rails connected to this rail by a connector are supplied via the same power supply with electrical energy, so that they are put into operation can. As a result, the lamp is very flexible, since depending on the application almost any number of rails in the manner of a light strip can be plugged one behind the other. The power supply can be brought into contact-effective connection by a plug with one end of a rail. This system also significantly reduces the cost of manufacturing and warehousing. It is also possible to arrange the rails differently as needed and to change the arrangement as desired without having to procure new lights or rails. This gives you a very flexible system.

In a luminaire of the type just described, it is preferably provided to provide a securing element on each plug connection of two rails, which secures the plug connection against unintentional release, which could happen, for example, if someone accidentally hits the rails. The easiest way is when the fuse element with the two ends of the two rails in the region of the connector by clipping, plugging or latching is connected laterally or from above. Such types of connections are solvable, so that the rails can also be separated from each other again as desired. It is also advantageous in such a luminaire to provide an indicator on the plug connection, which indicates whether the two rails are electrically connected to one another in an electrically effective manner and the plug connection has been produced correctly. If a securing element is used, then the indicator can be arranged in particular on this securing element.

In a further preferred embodiment of the luminaires described above, a respective contact element is provided, which produces the electrical contact between the two ends of two rails, wherein it can additionally or alternatively serve as a securing element. This contact element is inserted, for example, in or at the ends of the rails. The advantage here is that at the individual lights or rails no plug with protruding contacts, such as male plug, must be provided, which could bend or break during transport or storage.

Preferably, the lamp is designed as a system lamp. This means that there are different uses. Thus, the lights can be attached directly to the ceiling or wall of a room by means of a holder, such as a headband, a chain or the like. Furthermore, it is also possible to arrange the rails in housings, so that in turn other types of luminaires can be realized, such as, for example, louvre luminaires. You can use a rail individually or combine by making the previously described connector with several other rails to produce a lamp. The result is a complete lighting system, which is flexible and by the use of always the same or similar components inexpensive in the production and warehousing. In a further preferred embodiment, an energy store, such as an accumulator, is provided, in which the energy required for the operation of the LEDs can be stored. This has the advantage that the electrical energy needed for operation is at low load times, for example at night, fed and then used at another time. Thus, the operating costs of the LEDs can be reduced. The energy storage can be operated for example by means of an intelligent control. This can bring the energy storage in its state of charge, if, for example, the charge located on the energy storage sinks too far. The state of charge can also be made dependent on other factors, such as the time, the presence of cheap night-time electricity, the operating state of the premises in which the light is located or the like. The control of the energy storage can also be performed programmable.

The energy store is preferably arranged in a space located in the rail, at one end of the rail, in particular in the plug connection or in the housing. Of course, it is also possible to provide the energy storage externally.

Further advantages and embodiments will become apparent from the following description, the subclaims and the drawings. In the drawings, the lamp is shown in several embodiments. Show it:

Fig. 18: Assembly of two rails with contact element Fig. 19: a lamp with rail according to FIG. 16 in an exploded view

Fig. 1 shows a rail 20 according to the invention a luminaire 10 in a first embodiment in section. The light-emitting device 1 1 is shown only schematically. It comprises a circuit board 15 on which one or more LEDs 1 8 are arranged. Between the board 15 and the rail 20, a heat conducting means 16, such as a thermal paste or heat conducting foil is arranged. As a result, the heat generated by the LEDs 18 can be delivered to the rail 20 faster and easier. The rail 20 has an aluminum profile 28. This has on its one side 21, the opening 23 through which the light which is emitted from the light-emitting device 1 1, can escape to the outside. The circuit board 15, the heat conducting means 16 and the LEDs 18 are shown in Fig. 1 only very schematically.

On the inner side 12 of the rail 20, two mirrors 13 are respectively arranged, which reflect the light emitted by the light-emitting device 1 1 and emit light in the direction of the opening 23. The mirrors 13 are supported on each inner side 12 of the rail 20 in recesses 14. Of course, the inner side 12 of the rail 20 itself may be polished or provided with a reflective coating or otherwise reflective designed to produce the aforementioned effect.

The opening 23 is closed by the prism plate 24, which is indicated only by dashed lines, which ensures that the light emitted by the light-emitting device 11 is distributed in the space. The prismatic disk 24 has a honeycomb-shaped profile. In the region of the one side 21 of the rail 20, receptacles 27 are provided in the embodiment shown here, in which the prismatic disk 24 can be attached. In addition, the counter-latching element 25 is still recognizable, whose function will be explained later in more detail. These counter-locking elements 25 are used to install the rail 20, for example, in a housing 60 or the attachment of the lamp 10 to a wall or ceiling or the like and help to provide a complete lighting system, as about the counter-locking elements 25 various components on the rail 20 are fastened.

The designated A section of FIG. 1 is shown in Fig. 2 in more detail. A cooling device 26 for the heat emitted by the light-emitting device 11, in particular by the LEDs 18, can be seen here. Thus, it is ensured that the light-emitting device 1 1 does not overheat and the LEDs 18 or the associated electronics 19, which is used for control, is damaged. The cooling device 26 is here designed in the form of ribs or serrations which conduct the heat generated by the light-emitting device 1 1 to the outside. This cooling device 26 can be formed directly when creating an aluminum profile 28 with, for example, in the production of the aluminum profile 28 by aluminum extrusion. The aluminum also has the advantage that it can conduct the heat well to the outside.

Furthermore, one recognizes in Fig. 2 still partially the arranged on the inside 12 of the rail 20 mirror 13. This mirror 13 is supported here in two recesses 14, on the one hand to prevent slipping, but the mirror 13 on the other hand easy to install and again to make removable from the rail 20.

Figures 3 to 7 show the attachment of two rails 20 by means of a connector 32 to each other. For this purpose, each of the rails 20 has at each of its ends 3 1 via a respective plug 30. These plugs 30 may be formed, for example, as male and female plugs 30, as here in particular from Figures 4 and 5 can be seen. Other forms of a plug 30 are of course conceivable. To the connector 32nd To manufacture, the two rails 20 are aligned with each other and the plug 30, which are located at the ends 31 of the rails 20, inserted into one another, so that an electrically contact-effective connection is formed. After this connector 32 has been made, then a fuse element 40 can be arranged on this connector 32 to prevent inadvertent release of the connector 32. Advantageously, the securing element 40 is clipped on the rails 20, plugged or locked with these. For this purpose, the securing element 40, for example, come into operative connection with the counter-latching element 25 of each of the rails.

In the advantageous embodiment shown here, an indicator 41 is additionally provided, which is arranged here on the securing element 40. This indicator 41 indicates whether the connector 32 has been made correctly and / or whether an electrically contact-effective connection of the two connectors 30 is present and / or whether the fuse element 40 has been correctly attached to the connector 32. As a result, assembly errors can be minimized.

It will also be seen from Figures 3 to 7 how the fastener 50 is secured to the rail 20, and then cooperate with a bracket 52 to allow the lamp 10 to be mounted. In the present embodiment, the holder 52 has a hook, which is engageable with an eye, another hook, a bracket or the like on a ceiling of a room in operative connection to secure the lamp 10 in space. The fastening means 50 and the holder 52 are also height-adjustable to each other, resulting in a great flexibility in the alignment of the lamp 10 in the room.

To attach the fastener 50 to the light 10, it cooperates with the rail 20. For this purpose, a plastic part 53 is provided, which is detachably fastened to the rail 20. For example, as methods for releasable attachment latching, Verclipsen or plugging on. In the present embodiment, the plastic part 53 has the Locking element 51, which is engageable with the counter-latching element 25 of the rail 20 in mechanical operative connection, as shown in Figures 3 and 4, for example. The fact that the counter-latching element 25 is integrated into the aluminum profile 28 of the rail 20, an attachment of the plastic part 53 and thus the fastener 50 at almost any point of the rail 20 is possible, which in turn a great deal of flexibility in the attachment of the lamp 10 in means a room. The plastic part 53 may be formed integrally with the fastening means 50. But it can also, as here, the fastener 50 screwed to the plastic part 53, locked, riveted, welded or otherwise secured.

After complete assembly of the two rails 20 to each other and the production of the connector 32 and the mounting of the fuse element 40 then a lamp 10, as shown in Fig. 8, arise, which can illuminate a room here.

9 and 10 show a further use of the rail 20 according to the invention using a housing 60 according to the invention, each with three openings 61 for receiving the rails 20, not shown here. In Fig. 10 are still locking points 63 can be seen, each of which laterally to the Breakthroughs 61 are arranged and on which the rails 20, preferably with the interposition of fastening means not shown here 50, can be latched. Furthermore, holes 62 are still provided, which form a kind of perforation. This serves to exchange air, so that the heat emitted by the rails 20 heat can escape better from the housing 60. In this context, it is also advantageous not to provide an additional cover for the housing 60, but to leave the top of the housing 60 open. As a result, the ambient air can circulate optimally and further dissipate the heat produced by the LEDs 18, which is conducted into the cooling devices 26.

The dashed lines indicated prismatic disk 24 is placed in two receptacles 27 on one side 21 of the rail 20. By the special Embodiment of the receptacle 27, it is also possible to subsequently replace the prismatic disk 24 in the individual rails 20. In order to make the rail 20 more handy overall, it may still have a cap at both ends 31, which preferably consists of plastic and is easily plugged onto the rails 20. The cap can be designed so that the electrical connection lines, which are necessary for the operation of the LEDs 1 8, can be guided through them.

1 to 13 show the fastening means 50. This serves to support the rail 20 on the housing 60 and secure. The fastening means 50 is embodied here as a clip and has the latching element 51 on its one side 54. This latching element 51 can be brought into operative connection with the counter-latching element 25 on a rail 20 and thus produces a latching connection. Of course, it is equally possible to provide the counter-latching element 25 on the housing 60.

In order to produce a secure support between the housing 60 and the rail 20 by means of one or more fastening means 50, the fastening means 50 on its other side 55 still has a projection 56 which, for example, with a detent 63, which here on the housing 60 of FIG 10 can be seen, occurs in operative connection by the projection 56 is at least partially introduced into the latching point 63. Again, it is of course possible to provide the projection 56 on the rail 20. A ceiling lamp according to the invention in the assembled state, Figs. 14 and 15. In the housing 60 three rails 20 are arranged in the openings 61. The rails 20 each comprise an aluminum profile 28 and are clipped by means of three pairs of fastening means 50 on the housing 60. The rails 20 are arranged in the apertures 61 so that they lie with their one side 21, which has the prismatic disk 24 in the illumination direction. If the LEDs 18, not shown here, are switched on, then the light emitted by the LEDs 18 passes through the prismatic disc 24 out of the ceiling light and can illuminate the space underneath.

The ceiling light shown here can serve as a recessed luminaire in a grid ceiling or as a suspension lamp. For this purpose, four height-adjustable slide 70 are provided on the housing 60, which are adjustable so that the distance of the ceiling light from the ceiling of the room is adjustable and the ceiling light itself by means of the carriage 70 is adjustable. Of course, the ceiling light can also serve as a surface light and the carriage 70 may be designed differently or there may be a completely different fastening system.

A second embodiment of the rail 20 according to the invention are shown in FIGS. 16 to 19. The rail 20 far here again in a known manner a receptacle 27 for the prismatic disk 24, not shown, as well as recesses 14 for the indicated mirror 13 and counter-latching elements 25. In addition, again the circuit board 15 with an LED 18, and the heat conducting means 16 is shown schematically. In its upper region, the rail 20 comprises rib-shaped cooling devices 26. However, a second type of cooling devices 26 is also provided in the side walls of the rail 20. These are also wavy or rib-shaped, but smaller, in terms of numbers more executed. This also dissipates the heat transferred to the aluminum profile 28 of the rail 20. Furthermore, one recognizes the space 17, in which, for example, an electronics 19 can be arranged, as the exploded view in Fig. 19 can be removed. This electronics 19 can serve the control of the light-emitting device 1 1. When the controller 19 is placed within the rail 20, the individual rails 20 can be easily interconnected to form a luminaire, such as shown in FIG. Fig. 18 shows how two rails 20 are connected together. In order to establish the electrical contact between the rails 20, a contact element 42 is used, which is connectable to the plugs 30 of the rails 20. As a result, both sides of the rails 20 can be provided with female plugs 30 which are not bent or damaged as quickly as male plugs 30.

It is also apparent from FIGS. 18 and 19 that the cover caps have passages 33 which are closed by an element with predetermined breaking point. If a plurality of rails 20 are successively fixed in contact with one another in contact with one another by means of a plug connection, then corresponding connection cables need only be connected to one of the rails 20. These are then feasible through one of the passages 33, wherein the covering element is removed by breaking it off at the predetermined breaking point. At the points where no connection cables are used, then the element can be left in the cap to protect the interior of the rail 20, in particular the space 17, from contamination.

Finally, it should be pointed out that the embodiments shown here are merely exemplary realizations of the invention. This is not limited to this. On the contrary, modifications and modifications are possible.
