Waterproof luminaire

The present invention relates to a wet room light having a base well and a translucent cover which is releasably supported on the base well.

A state-of-the-art moisture-proof luminaire usually has an elongate base trough and a light-permeable and likewise elongate cover fastened to the base trough. The base tray is used in particular the holder and receiving the electrical components of the lamp; light is emitted from the luminaire through the translucent cover. Between the base trough and the cover a sealing connection is provided over the entire circumference of the base trough, which is usually ensured by a corresponding seal, which is arranged in a circumferential groove, so to speak in a sealing channel of the base trough.

In wet room lights there is generally the need to make the lights in particular by suitable shaping so that deposits as little dirt on the lamp and that water can flow as well as possible on the outer surface of the lamp. However, these objectives are achieved only to a certain extent according to the prior art, because usually the

Outside of a moisture lamp in several places not even and therefore prone to dirt deposits. This is caused for example by closures for holding the cover to the base tub, recesses for fastening elements for mounting the lamp to a ceiling, a bulging, given by the sealing channel gradation at the bottom of the base tub,

Feeders, mounting scenes and the like. It is also sometimes envisaged that the wet room light should be attached to a ceiling or mounting rail or the like, with a certain distance is provided between the base and the ceiling or mounting rail, so that in this way on the lamp a surface is formed on the can deposit dirt. The said outside unevenness are also disadvantageous with respect to an aesthetic design possibilities of the moisture-proof lamp.

The present invention has for its object to provide a moisture lamp, which has improved properties with respect to dirt deposit and water drainage and thereby has better possibilities of shaping.

This object is achieved according to the invention with the wet room lamp mentioned in the independent claim. Particular embodiments of the invention are indicated in the dependent claims.

According to the invention, there is provided a wet room light comprising a base well and a translucent cover releasably supported on the base well. The base trough has at least partially an inner layer and an outer layer, wherein the outer layer forms an outer surface of the moisture-proof lamp.

With the outer layer, a component of the moisture-proof light, which forms potential dirt deposit points, can be covered, so that a

Dirt accumulation at this point can practically be ruled out or at least significantly reduced. For example, in this way closure elements, spouts, fasteners and the like can be covered. Also, for example, a step on a sealing channel or a surface facing a ceiling surface can be virtually eliminated as the outer surface of the moisture lamp, so that attachment surfaces for dirt and water are reduced. The outer layer also makes it possible to make the outside of the base well evenly, whereby the possibilities of aesthetic design are improved.

Advantageously, the inner layer consists of a material which is different elastic to the material of the outer layer. In this case, it can furthermore be provided, in particular, that the outer layer consists of a more elastic material than the inner layer. This makes it possible in particular, even a movably provided component, such as a movable Closure element to cover with the outer layer, and yet to maintain the possibility of movement of the component, by allowing a motion transmission through the outer layer is made possible. Preferably, the outer layer may consist of rubber, polyurethane, neoprene or silicone.

However, it can also be provided that the inner and the outer layer consist of the same material, preferably of polyester or polycarbonate.

It can be provided that the outer layer of the base trough consists of an elastic material; Advantageously, the outer layer consists for example of rubber, polyurethane, neoprene or silicone. The base tub can be made for example of a plastic material, such as polyester or polycarbonate.

Further advantageously, the outer layer completely surrounds the inner layer on the outside. In this case, therefore, the outer layer forms, as it were, a "dress" or a "coat" around the inner layer. Thus, for example, an elongated moisture-proof luminaire may be provided, which has an elongated base trough whose outer surfaces are completely formed by the outer layer. This allows a particularly even design of the outer surface and thus a particularly high dirt resistance, a particularly good drainage possibility and also very good design options.

Advantageously, the moisture-proof luminaire is designed such that the translucent cover is detachably supported on the inner layer of the base trough, wherein the moisture-proof luminaire further comprises at least one closure element for releasably securing the cover to the inner layer of the base trough, and wherein the closure element of the outer layer at least partially, preferably completely covered. It can therefore be provided in particular that the

Closure element does not surround the outer layer. In this way, the closure element can evenly cover. By way of example, the closure element may be a clamp which grips an edge region of the inner layer of the base trough and an edge region of the cover from the outside. In this case, a plurality of preferably similar closure elements can be provided.

In this case, the closure element is advantageously designed in such a way that, in a closed state, it holds the cover on the inner layer of the base trough and, in an opened state, does not hold the cover on the inner layer of the base trough, wherein the closure element is furthermore designed such that it passes through a press can be opened and / or closed. In this case, owing to the elastic property of the outer layer, an actuation of the closure element, that is to say an opening or closing through the outer layer, can be made possible. Among other things, this also facilitates maintenance work that must be carried out inside the moisture-proof luminaire.

Advantageously, the outer layer is designed such that the pressing can be carried out through the outer layer, wherein preferably the outer layer has a marking at a location at which the pressing is provided. For example, it is possible to provide a first point for pressing to open the closure element and a second point for pressing to close the closure element, wherein the outer layer preferably has two corresponding markings.

The closure element may comprise, for example, a spring steel strip, which can be displaced in the manner of a cracked frog by pressing in two different states, wherein the closure element is open, if the spring steel strip is in a first state, and closed, if the spring steel strip in a second State is. The states of the spring steel strip can be stable and / or metastable and / or bistable, Such a closure element can also be advantageously used in the case of a corresponding luminaire without an outer layer.

Further advantageously, the outer layer forms a holder of the cover on the base trough. This eliminates the need for a corresponding closure element. Advantageously, the outer layer has a hole for a cable entry. As a result, a Durchrührungsmöglichkeit is formed for a supply line. This enables a particularly reliable sealing situation in the cable entry area. The outer layer can be even in this area despite even

Design of its outer surface form a seal or additional seal around the cable entry.

Advantageously, the wet room lamp further comprises a contact surface, which is intended to rest on a wall or ceiling, wherein the outer layer has a sealing lip, which is arranged at the edge of the contact surface. This is particularly advantageous in the case of uneven cultivated areas, since the outer layer can adapt to unevenness to a certain extent due to its elastic property.

Further advantageously, a drainage channel for water is arranged in the outer layer and / or between the outer layer and the inner layer. This is advantageous, for example, in the event that accumulations of water between the moisture-proof light and an acreage, for example a ceiling, can not be ruled out. This can be the case, for example, with an uneven ceiling. Through the drainage channel then enriched water can be safely out there.

Advantageously, the inner layer and the outer layer constitute two separate components. In this case, since the outer layer is more elastic than the inner layer, it may be provided that the outer layer is pulled over the inner layer in the manufacture of the moisture proof luminaire. Alternatively it can be provided that the inner layer and the outer layer consist of one piece. For example, it can be provided that the outer layer is formed by foaming the inner layer or that the outer layer and the inner layer are made by a multi-component injection molding process, for example a two-component injection molding process.

Advantageously, the outer layer has a contact surface for abutment with a carrier system part, for example a carrier tube. Advantageously, the outer layer forms a drip edge.

The invention is explained in more detail below with reference to two exemplary embodiments and with reference to the drawings. Show it:

Fig. 1 1 is a perspective sectional view of the moisture-proof light shown in Fig. 8.

FIGS. 1 and 2 show a first exemplary embodiment of a damp-proof luminaire 1 according to the invention, each in a perspective view in a partially cutaway state. One recognizes an elongate base trough 2, which has an inner layer 4 and an outer layer 5. For better visibility of the structure, the outer layer 5 is shown in the illustrations of Figures 1 and 2 in a partially cut state.

The base well 2 is used in particular for receiving the components for

Light production. This is prior art and therefore will not be discussed in detail at this point.

According to the first embodiment, the inner layer 4 of the base trough 2 is made of a plastic material such as polyester or polycarbonate and the outer layer 5 of rubber, polyurethane, neoprene or silicone, for example, such that the outer layer 5 is more elastic than the inner layer 4.

The outer layer 5 is designed so that it is externally very evenly shaped and thus represents virtually no significant attachment points for dirt. It can therefore be formed by the outer layer 4, a substantially smooth or closed outer shell of the base trough 2.

It is provided in the embodiment shown here that the outer layer 5, the inner layer 4 on the outside completely surrounds, so to speak, sheathed or sheathed. The outer layer 5 thus forms an outer surface of the moisture-proof luminaire 2 and more particularly an outer surface of the base trough 2. Furthermore, the flamesight lamp 1 comprises a translucent cover 8 which is connected to the base trough 2 and which is detachably mounted on the base trough 2. To seal the connection between the base tub 2 and cover 8, a seal is provided, as it is known per se from the prior art. As can be seen, for example, in FIG. 5, this seal is arranged in a groove 32 which extends at the bottom at the edge of the inner layer 4.

The holder of the cover 8 is provided on the side of the base trough 2 on the inner layer 4 and not on the outer layer 5. For releasable support a closure element 12 is provided. A total of several, for example - as shown in Figures 1 and 2 exemplified - six similar closure elements 12 may be provided.

For example, as can be seen from FIG. 5, the closure element 12 can be formed by a clamp which clasps an edge region of the inner layer 4 on one side and an edge region of the cover 8 on the other side. The closure element 12 comprises the seal in the groove 32 from the outside. The closure element 12 may in particular be configured such that it is not in direct interaction with the outer layer 5. Therefore, such a closure element 12 can be advantageously provided even with a corresponding moisture lamp, which has no outer layer 5.

As is clear from a joint examination of FIGS. 1 and 2 and also shown in FIG. 5, the closure element 12 is covered by the outer layer 5, namely completely covered on the outside according to this embodiment, so that it is practically "invisible" Outer layer 5 therefore covers the entire closure element 12 from the outside. In this way, no outer surface of the moisture-proof luminaire 1 is formed by closure element 12 and therefore does not constitute a potential soil deposition site. However, it may also be provided that closure element 12 is only partially, for example is largely covered by the outer layer 5.

The closure member 12 can be placed in a closed and an open state. In the closed state, which is shown in the drawings, is the cover 8 gchaltcrt by the closure member 12 on the base trough 2. In the open state, the cover of the base tray 2 can be solved.

In the exemplary embodiment, the closure element 12 comprises a spring steel dispute, which can be displaced by pressing in two different states, wherein the closure element 12 is opened, if the spring steel strip is in a first state, and closed, if the spring steel strip in a second state. The closure element 12 can form a rocker lock. The elasticity of the outer layer 5 is chosen so that through the outer layer 5 through the closure element 12 can be pressed from the closed state to the open state and preferably also the other way round.

As mentioned above, however, such a closure element 12 may also be provided in the case of a moisture-proof luminaire without an outer layer 5.

As indicated by way of example in FIGS. 2, 4 and 5, it may be provided for easier handling that the point at which the pressing on the outer layer 5 is provided for opening the closure element 12 is identified by a marking 16. This marking 16 represents, so to speak, a pressure field in the form of an optically highlighted area. Alternatively or additionally, it may be provided that the location is made haptically detectable, that is to say it can be felt or felt.

The closure element 12 can thus be designed in particular so that it - in the closed state - snaps at a pressure of the provided with the mark 16 position of the outer layer 5 in the open state, ie in an open position and, accordingly, the latch or holder between the Base trough 2 and the cover 8 releases.

Alternatively it can be provided that the outer layer 5 itself is formed as a holder for the base trough. As shown in Fig. 7, for an implementation of an electrical supply line, so a Kabelein guide in the wet room I I, for example, a feed spout 28 may be provided on the front side. The outer layer 5 may have at this point a hole 18 for the cable guide. By a suitable choice of the size of the hole 18 may be formed in this way an additional seal in the manner of a sealing lip without the uniform outer shape of the outer layer 5 of the base trough 2 would have to be changed for this purpose.

The moisture-proof luminaire 1 according to the first exemplary embodiment illustrated in FIGS. 1 to 7 is designed as a ceiling-mounted luminaire. As can be seen, for example, from FIG. 3, the damp-proof luminaire 1 has an upwardly directed contact surface 34 for this purpose. For attachment to the ceiling, the moisture-proof luminaire 1 has at least one fastening element 26.

As can be seen, for example, from FIG. 5, the outer layer 5 has a sealing lip 14, which is designed such that it comes to bear against the ceiling in the intended state of the moisture-proof luminaire 1. The sealing lip 14 thus forms the edge of the contact surface 34. By means of the elasticity of the outer layer 5, it is possible to achieve a "suction" on the ceiling with this sealing lip 14. Such a sealing lip 14 can be used to bring about practical use - with a flat top no water and no dirt can reach the top of the moisture-proof light 1. The outer layer 5 has "adapter function" in this sense.

As sketched in FIG. 6, it can furthermore be provided that at least one of the outer layer 5 and the inner layer 4, preferably the front side, is provided

Outflow channel 20 is arranged for water. If water accumulates between the base tub 2 and the ceiling, this can flow out through the drainage channel 20, without causing any damage to the moisture-proofing luminaire 1. A water entry into the space between the base tub 2 and ceiling could not be excluded, for example in the case where the ceiling is not flat and the tightness can not be fully guaranteed by the sealing lip 14. However, the drainage channel can also be arranged within the outer layer 5. Preferably, the outer layer 5 is formed at its lower edge as Abtroptkante 24.

According to the first embodiment, it is provided that the outer layer 5 is formed by a separate component. It is provided that initially the inner layer 4 and the outer layer 5 of the base trough 2 are manufactured separately and in a further step, the outer layer 5, which consists of a more elastic material than the inner layer 4, via the inner layer 4, where the at least one closure element 12 and the feed spout 28 are already mounted is pulled. The elasticity of the outer layer 5 is advantageous because it allows manufacturing tolerances can be accommodated. Furthermore, it can be provided that the hole 18, which is provided in the outer layer 5 in extension of the feed spout 18 to the outside for Kabeleinfuhrung, is only drilled when the outer layer 5 is pulled over the inner layer 4.

Alternatively, it can be provided that the outer layer 5 and the inner layer 4 consist of one component, for example, the outer layer 5 may be formed by foaming the inner layer or the outer layer 5 and the inner layer may by a multi-component injection molding, for example a two-component injection molding process may be formed.

According to a second exemplary embodiment, which is shown schematically in FIGS. 8 to 11, it is provided that the moisture-proof light 1 'can be arranged or mounted on a carrier system. Such a carrier system may, for example, have a carrier tube 30. Unlike the first

Exemplary embodiment, the outer layer 5 'in the second exemplary embodiment designed such that a continuous as possible transition to the support tube 30 and to the carrier system can be obtained. For this purpose, the outer layer 5 has a contact surface for abutment with the carrier system part, for example the carrier tube 30. Due to the elastic property of the outer layer 5 can be designed a particularly well-fitting contact surface; As a result, the susceptibility to dirt can be further reduced. Incidentally, the wet room lamp 1 'according to the second embodiment is formed analogously to the first embodiment.

Due to the two layers 4, 5 of the base trough 2, it is generally to be expected that the operating temperature prevailing in the base trough during operation is higher than in the case of a single-layer base trough. This may be disadvantageous in individual cases. However, this may also be advantageous, namely when the moisture-proof light is used in a comparatively cool environment, for example in a cold room or the like. Due to the low ambient temperatures with regard to the effectiveness of the moisture-proof luminaire, it makes sense to use high temperatures inside the luminaire.
