Description

The present invention relates to a lighting system with an elongate support member to which lighting units are attached. The light band system is designed such that the subsequent attachment of add-on elements, which have optical means for influencing the light output, is possible.

Lichtbandsysteme are known in different forms. They are widely used, as they offer a high degree of flexibility in the individual planning of lighting structures compared to fixed or built-in luminaires. Since such systems consist of individual elements that are assembled according to the modular principle, the entire arrangement can be easily adapted to the premises to be illuminated.

A well-known lighting system, which, for example, in the DE 100 25 647 A1 the applicant is described in 1 shown. The basic framework of the well-known trunking system 100 is by an elongated mounting rail 10 formed, which is formed by an open toward the bottom, U-shaped profile element. This mounting rail 10 can be mounted either directly on a ceiling or suspended and serves to hold several lighting units, in 1 a single lamp unit is shown, which is denoted by the reference numeral 30 is provided. In this context, it should be noted that 1 only a short section of the lighting system 100 shows. Actually, the mounting rail 10 significantly longer than the attached lighting unit 30 , so usually several lighting units 30 - in particular flush - one behind the other on the mounting rail 10 are attached.

The lighting unit 30 In turn, initially consists of an elongated cover rail 31 , which from the bottom to the mounting rail 10 attached and attached. With the help of actuators, which via openings 35 in the cover rail 31 are accessible, it can be both a mechanical attachment to the mounting rail 10 as well as an electrical contact within the mounting rail 10 running power lines. The illustrated lighting system 100 characterized by the fact that a free arrangement of the lighting units 30 on the mounting rail 10 what allows the flexibility of the lighting system 100 additionally increased. However, there are also known light band systems in which the lighting units can be arranged only at fixed predetermined positions.

The lighting unit 30 also has retaining elements on the two end faces 32 on which the holder of lamp holders 33 serve. In these versions 33 is in the illustrated Ausfürungsbeispiel an elongated light source 34 used in the form of a fluorescent lamp. The power supply of the lamp 34 via lamp operating means, which at the top of the cover rail 31 arranged and accordingly after mounting the lamp unit 30 in the recording room 11 the mounting rail 10 are arranged.

The fastening to the mounting rail lamp units can be designed differently and in particular also have reflectors or other optical elements to influence the light output. Not infrequently, however, also lighting units in the in 1 used form, which have only the light source, but not other elements which surround the light source. The lighting units are usually mounted directly behind one another on the mounting rail, so that no free space between them.

It has now been found that there is often the need, in such light bands, in which the simple luminaire units described above are used to subsequently attach attachments, which have optical means to influence the light output in a certain way. Also, for optical reasons, the retrofitting of such attachments is often desirable to give the system a different look. In this context is from the EP 2 107 293 A1 a solution known in which the lamps of the lamp units are subsequently surrounded by a cuboid, transparent cover. The covers are in this case designed such that they can expand unhindered in the longitudinal direction, which is achieved in that they consist of a substantially U-shaped and open at its end profile elements.

Depending on the type of field of application for a luminaire or for a lighting system, it is often desirable to protect the luminaire from external influences. In particular, there is often the need to design the luminaire in such a way that it corresponds to the degree of protection IP50, that is to say it is dust-proof. For this purpose, it is necessary to shield the sensitive components of the lamp in a suitable manner from the environment. However, this is not possible in a satisfactory manner with the retrofittable optics known hitherto.

The present invention is therefore based on the object to provide a solution which the subsequent attachment of optics or in general of add-on elements to lighting units of a lighting system allows, in particular by the attachment of the add-on elements, the protection of the lamp against external influences to be improved.

The object is achieved by a lighting system with the features of claim 1 and by a mounting element according to claim 9. Advantageous developments of the invention are the subject of the dependent claims.

The solution according to the invention is based on the idea of providing sealing means on the attachment element to be attached to the lamp unit, which seal means allow a seal between the lamp unit and the attachment element in the mounted state. In particular, the sealing means are provided on one of the lamp unit facing investment area.

According to the present invention, a lighting system with an elongated support member is accordingly proposed, to which at least one lamp unit with an elongated light source is releasably attached, wherein the lamp unit is associated with a surrounding light source attachment element which has optical means for influencing the light output and releasably attached to the Luminaire unit can be fastened, and wherein the attachment according to the invention comprises at its the lamp unit facing contact area sealing means.

Further, an attachment for releasable attachment to an elongated lamp of a lighting system is proposed, which has optical means for influencing the light output, according to the invention, the attachment element has at its the lamp unit facing contact area sealing means.

By attaching the aforementioned sealing means can accordingly be sealed, the connection area between the lamp unit and the attachment element or the optics, so that in particular the dust cover for the lamp unit is increased. In particular, this makes it possible to achieve the aforementioned degree of protection IP50. In order to facilitate the subsequent attachment to the lamp unit, it is preferably provided that the attachment element can be latched to the lamp unit.

According to a preferred embodiment, the attachment has a pot-shaped housing with one of the lamp unit facing and for engagement at this particular opening, in which case the sealing means are arranged on the circumference of the opening. In particular, the opening may be elongated, wherein the sealing means have two extending along the longitudinal side of the opening seals.

In order to adequately protect the lamp arranged inside the housing in the mounted state of the attachment element, it is of course necessary for the attachment element to completely surround the lamp. That is, in the present case elongate lamp units end caps or generally end portions are required, which complete the attachment element or the optics frontally. Here, however, there is the problem that often the lighting units of the lighting system are flush with each other. If subsequently an optic should be removed, the position of the luminaire units should remain as unchanged as possible, since otherwise the retrofitting of the optics would be associated with too much effort. However, this again means that the required end caps of the attachment may not take up too much space. According to a particularly preferred embodiment, it is therefore provided that the end caps terminate flush with the end regions of the lamp unit. Often, the lamp units each have at least one socket holder for holding a lamp socket, in which case it may be provided in particular that the end caps each receive an end portion of the associated socket holder flush.

The lower end of the attachment element is preferably formed by a transparent light exit disc. However, since access to the lamp for maintenance purposes should be required, it is preferably provided that the light exit plate is releasably secured to the housing of the attachment. Also at the transition between the light exit plate and the housing of the add-on element sealing means are then preferably provided in order to achieve the desired dust protection. The add-on element may further internally have a luminaire grid for influencing the light output.

The invention will be explained in more detail with reference to the accompanying drawings. Show it:

1 a section of a known from the prior art trunking system;

2a and 2 B Representations of a holder used in the lighting units of the lighting system;

3 the view of an end portion of a retrofit attachment according to the invention;

4 the end cap of the attachment element according to the invention;

5 the end cap with the socket holder received therein;

6 a section AA the 5 such as

7 a lighting unit with the attached thereto attachment.

This in 1 shown lighting strip system 100 was already explained at the beginning. It will be added to the DE 100 25 647 A1 in which this system is described in detail. The present invention supplements such a lighting system 100 which makes it possible the lighting units 30 to be subsequently provided with an optic to influence the light output. The optics should at the same time also form a dust cover for the luminaire unit, so that ideally the degree of protection IP50 is achieved, the luminaire is therefore dust-proof. Ultimately, an arrangement should result, as exemplified in 7 is shown. This figure, viewed in isolation, shows a lighting unit 30 , on the underside of which generally denoted by the reference numeral 50 provided optics is arranged.

A more detailed view of the retrofittable optics 50 is in 3 shown. It has an elongated housing 51 on, which primarily by two side walls 52 is formed, which towards the top - ie in the direction of the lamp unit 30 - are inclined inwards. It results from this at the top of the housing 51 a narrow elongated opening, which for attachment to the lamp unit 30 is provided. In particular, it is provided that in the assembled state, the upper edges 53 the side walls 52 on the elongated cover rail 31 the lighting unit 30 issue. Furthermore, in this area of the side walls 52 Locking means provided, which with the lamp unit 30 cooperate in such a way that when applying the optics 50 to the lamp unit 30 automatically a locking and thus attachment is achieved.

The bottom of the case 51 the optics is through a plate-shaped Lichtabstrahlelement 55 formed, which has a surrounding frame 56 and a transparent light emitting disc located therein 57 having. About this disc 57 then finally the light output takes place, wherein for influencing the light within the housing in the illustrated embodiment, in addition, an elongated luminaire grid 60 consisting of longitudinal reflectors 61 and transverse reflectors 62 is provided. About this grid 60 The light output can be limited to a certain angle range, so that the emitted light is blinding. Alternative to the use of the lighting grid 60 Of course, there would also be the possibility within the housing 51 the optics 50 to arrange other light influencing means. It would also be conceivable, the light exit window 57 to be provided with prismatic structures or the like. The light-emitting element 55 is detachable on the housing 51 attached in order to be able to be removed if necessary, for example, for a lamp change can. The connection between light emitting element 55 and housing 51 Again, preferably via suitable locking elements.

The desired dust protection for the lamp unit 30 is achieved through various measures, which are described in more detail below. These measures are intended in particular to achieve the best possible sealing between the lamp unit 30 and the optics 50 to achieve.

A first measure consists in the fact that the transition between the upper edges 53 the side walls 52 the optics 50 and the cover rail 31 the lighting unit 30 as close as possible. These are on the edges 53 the side walls 52 elongated seals are provided which extend substantially over the entire length of the optic 50 extend. These seals are in 7 indicated and by the reference numeral 58 Mistake. They consist of an elastic material, for example. Rubber, which when locking the optics 50 with the lamp unit 30 is slightly deformed, thus sealing the transition between the two units. Here is the flexibility and thickness of these seals 58 chosen so that still the releasable locking between the optics 50 and the lighting unit 30 At the same time, however, no gaps of the gaps remain, via which dust into the interior of the housing 51 could invade.

Furthermore, it must be ensured that the penetration of dust is largely prevented even at the front areas. The attachment or the optics 50 has end caps for this purpose 70 on which the case 51 complete at the two opposite ends. It should now be noted that the housing 51 So the side walls 52 together with the end caps 70 the lamp of the lamp unit 30 should completely enclose, so in particular the lamp holders 32 should embrace. However, this may end caps 70 do not take up too much space, as in the event that multiple lighting units 30 flush one behind the other on the mounting rail 10 are arranged between the versions 32 two adjacent lighting units 30 only a minimal gap remains. This requires a special design of the end caps 70 , which will be explained in more detail below.

The particular in the 4 to 6 illustrated end caps 70 are designed in a special way, such that the optics 50 flush with the end of the lamp unit 30 can conclude. It should be noted that the respective ends of a lighting unit 30 primarily by the holder 32 which are closer in the 2a and 2 B are shown.

These frame holders 32 first have a first area 36 on, which forms a mounting plate, the front side of the rail 31 the lighting unit 30 is postponed. Vertical to this first area 36 closes a second area 37 on, which forms a receptacle for the lamp socket. Like the side view of 2 B can be taken, forms this second area 37 a vertical end wall 37a , where at the top of the first area 36 slightly survived.

This special embodiment of the socket holder 32 must be in the design of the end caps 70 be considered appropriately. For this purpose, it is now provided that the end caps 70 each having a peripheral frame having a side wall 72 encloses, with this wall 72 opposite the outer face of the frame 71 slightly offset inwards. Furthermore, in the upper part of the wall 72 a storage bag 73 formed, which in the attached state of the optics 50 on the lamp unit 30 the recording area 37 of the holder 32 receives. This storage bag 73 is with respect to the upper end of the frame 71 slightly offset downwards, so that further a recess or recess 74 is formed, in which - as in particular in 5 Shown is the end region of the first region 36 of the holder 32 is recorded.

It then results in the 6 shown in section arrangement that can be removed that the end cap 70 flush with the end portion of the socket holder 32 concludes. In other words, when putting on the optics 50 on the lamp unit 30 results in an overall arrangement, which in its length substantially the length of the lamp unit 30 equivalent. The end caps 70 do not extend the resulting arrangement or at most negligible, so that the optics 5 for already installed lighting units 30 can be attached later, without displacing the lighting units 30 would be required. This represents a significant advantage of the embodiment according to the invention.

Furthermore, the view of 5 be taken that at the transition area between end cap 70 and frame holder 32 at most extremely small gaps remain, so that as far as possible the penetration of dust is suppressed. Possibly. it would be conceivable to install additional seals in this transition region.

The subsequent assembly of the optics of the invention 50 then takes place in that first in the already assembled lamp unit 30 the lamp is removed. In a second step, then the optics 50 on the lamp unit 30 put on and locked with this. Subsequently, from the bottom of the optics 50 The lamp can be used again in the sockets. For this, the cover must be temporarily 55 be removed. In order to prevent the penetration of dust in this area, are preferably between the cover 55 and the housing 51 again provided suitable seals.

Ultimately, therefore, the solution of the invention opens up the possibility to install in a simple way add-on elements in luminaires of a lighting system, in which case no displacement of the installed lighting units is required. Furthermore, the penetration of dust can be prevented by the novel attachment elements and accordingly the degree of protection of the resulting arrangement can be increased.
