Description

The invention is directed to the improvement of a luminaire, in particular for a damp room.

Lamps for damp rooms have to comply with other luminaires increased requirements for their impermeability to moisture ingress. This is often at the expense of simple assembly of such lights. The same applies, however, to lighting, for example, in workshops that are increasingly exposed to soiling.

The present invention is based on the object to provide a lamp, in particular for a wet room, which is improved in particular with regard to their mountability. This object is achieved by a luminaire with the features of claim 1. Advantageous embodiments are specified in the subclaims.

According to the invention, a luminaire, in particular for a damp room (for example for bathrooms, workshops, garages, cold stores, agricultural buildings, carports or canopies) has a luminaire base with a (in particular substantially impermeable to dirt and / or moisture) base housing and a luminaire attachment with a (in particular against dirt and / or moisture substantially dense) attachment housing.

The base housing has attachment means adapted to secure the lamp base to a substantially planar wall. This can be a horizontal or vertical or otherwise oriented, also (especially in one direction) arched wall, so in particular a ceiling. The fastening device may for example be formed by fastening bores which pass through a flat wall of the base housing. Through these holes, the base housing can then be screwed to a flat wall. The fastening device can for example, also be formed by at least one resilient clip (for example, sheet metal and / or plastic), which can be screwed to the wall, and in which the base housing is adapted to be snapped. Such a fastening device has the advantage that the base housing for this does not have to have a bore and that the task associated with a hole tightness is avoided.

In particular, in order to access elements located in the base housing, the base housing has a housing opening (and in particular on a side opposite the fastening device), which is closed by a (in particular substantially moisture-tight) removably mounted lid.

This cover of the base housing is now part of the attachment housing. That is, when placing the lid and closing the base housing, the lamp completes by simultaneous placement of the attachment housing. Because the attachment housing contains the light source of the lamp (in particular at least one board with LED) and has (at least) a translucent wall (preferably at least on a side opposite the lid side). Because the attachment housing is preferably already tight against dirt and / or moisture, the luminaire according to the invention is then preferably completely sealed when the cover is put on, namely when the base housing with its lid is tight against dirt and / or moisture.

In order to supply the lighting means with power, the base housing has a (in particular moisture-tight) connecting passage in one of its walls, which is arranged, an electrical power supply line (in particular a 230V line end, which comes out of a room wall for connecting a lamp) to lead into the base housing into it. Simple and easy can be so first (without the possibly quite long or otherwise as spacious and possibly also more shock-sensitive lighting fixture attachment) the lamp base with the cover removed, for example, close to a 230V line end screwed to a wall and then lead the line end in the interior of the base housing into it. As a seal, for example, a rubber sleeve can be attached to the end of the line and then snapped and / or pressed in the connection passage, for example. As a "seal" according to the invention is very suitable, for example, a so-called PG-gland, which can be screwed after plugging and fixing on the line end in the connection passage (especially when the line passage is set in its diameter on standard PG gland elements).

The connection passage is preferably located in a side wall of the base housing (in an elongated base housing, preferably in one of the transverse walls to aesthetically "untouched" the longitudinal walls - with preferably short as possible trained basic housing then a lamp according to the invention can still mounted almost in the middle of a room be when a 230V line end in the center of the room comes out of the ceiling, even if the light-emitting attachment housing according to the invention may be considerably longer). The connection passage is formed, for example, as a circular hole approximately with a diameter which is slightly larger than the outer diameter of an example standardized 230 V line end. Possibly, for example, but also the connection passage is in the same flat wall (if such is provided for screwing to the flat wall, as described above for example by means of the mounting holes). Then, for example, the connection passage may be made significantly larger than the diameter of a lead end to be performed, and the edge of the connection passage may then be substantially sealed with, for example, a circumferential rubber seal against the flat wall.

In the base housing, an electrical light source supply device is arranged for the electrical supply, which is set up for the connection of the electrical supply voltage line and the lighting means (and in electrical line connection with a first connection element, for example a plug). The supply device can be, for example, a transformer and / or an electronic circuit, on which the color temperature can be adjusted, for example, in the case of LEDs as lamps. Especially in the case of LEDs as illuminants, an electrical illuminant supply device which has a sensor circuit part is particularly preferred. This may, for example, comprise a motion sensor and / or a brightness sensor (for example with a sensor surface integrated in an outside wall of the base housing). The sensor circuit part can then be set up to utilize movement at (adjustable) distance around the luminaire (for example by means of a microwave sensor) as a trigger for switching on the luminous means and / or when falling below one (adjustable, for example, by actuators on the device). Limit value of the brightness in the vicinity of the lamp to enable the lamp either to turn on a separate switch in the first place or (this alternative can be selected by a switch on the device) immediately turn on automatically and / or the lamp after a (for example by Actuators on the device adjustable) time after switching automatically off again. In particular, for these different adjustabilities, it is inventively advantageous that the base housing has the lid. Because when the so-equipped lighting supply device is located in the base housing including appropriate adjustment elements, the lid can be opened again at any time after the initial installation, and settings can be changed at any time afterwards.

To before placing the lid (in the later by the placement of the lid completed interior of the invention Moisture-proof luminaire) to produce the electrical supply of the luminous means, the luminous element attachment has a (second) connection element which is set up to connect the (first) connection element (the luminaire base) and thus the illuminant through the illuminant connection line to the illuminant supply device in line connection bring to. This second connection element is located outside of the (especially against dirt and / or moisture substantially dense) attachment housing to be accessible for connection - but is, through the lid, with the light source in the interior of the attachment housing in electrical line connection: when placed the lid on the base housing thus disappears so that the second connection element together with line connection therein, in the base housing.

The base housing is preferably only as small as necessary to accommodate the required and / or provided for the functions of the lamp elements therein. Thus, the base housing is preferably smaller than the attachment housing. This facilitates the assembly and looks visually perhaps more appealing.

The base housing preferably has a forwarding passage (in particular substantially impervious to moisture), which is set up to lead an electrical power supply line (in particular a 230V line) out of the base housing. This serves to connect another lamp next to the one to which the base housing belongs. This other lamp may be a luminaire according to the invention (and in turn have a forwarding passage so as to connect several lights according to the invention side by side).

For connecting a forwarding supply voltage line (which is then guided by such a forwarding passage) can be provided according to the invention a corresponding arrangement of Lustererklemmen and / or the supply device in the base housing a power supply output (In particular a 230V output) which is in electrical line connection with a power supply connection element (in particular a Luster terminal). These are then arranged in the base housing, preferably in the region of the forwarding passage.

As already indicated, the supply device can have at least one adjustment device which can be actuated when the cover is open and can be adjusted by means of the at least one electrical parameter of a light source to be connected. This can be, for example, the color temperature of an LED light source or, particularly preferably, the above-mentioned setting possibilities of a sensor circuit part.

Preferably, the base housing is elongate (in particular a straight elongated box, for example parallelepipedal, also with rounded edges and / or curved side walls) having a substantially planar, elongated wall adapted thereon to be substantially planar when secured by the fastening means Wall to abut.

Preferably, then the housing opening on the base housing has an edge which lies in a plane which is parallel to the flat wall. Thus, then preferably also the lid as a wall element of the attachment housing be flat and lie in a plane which is parallel to the flat wall on which the luminaire according to the invention is to be mounted.

Preferably, the attachment housing is elongated, preferably the attachment housing and the lid in the same direction. Preferably, the ends of the attachment housing are flat and / or planar. Thus, a plurality of lights, in particular with each longitudinally formed attachment housing, at the flat and / or planar ends directly "bump to beat" juxtaposed to long light strips are mounted side by side.

Preferably, the lid is exactly in the middle of a wall of the attachment housing integrated - preferably in the Wall facing the translucent wall of the attachment housing.

According to the invention, preference is given to a system of luminaires or a modular system for a luminaire according to the invention described above in which a plurality of luminous element attachments with different dimensions and / or electrical parameters have the cover, so that the different luminous element attachments can be replaceably attached to the luminaire base. Thus, for example, at the same luminaire base, which is already mounted in a wall, not only subsequently (for example, used, soiled or damaged) luminaire attachments can be exchanged for the same luminaire attachments (as is possible with the luminaire according to the invention), but in such a The system according to the invention, the lamp can also be subsequently adapted, for example, to changing requirements, for example, brightness, color temperature, reflector geometry or size of the lighting fixture. Particular preference is given to a system in which the different filament attachments are elongated and of different lengths.

According to the FIGS. 1 to 6 a luminaire 2 has a luminaire base 4 with a base housing 6 and a luminous element attachment 8 with an attachment housing 10.

The base housing 6 has according to FIG. 1 and 6 a fastening device 12, 12 ', which is adapted to fix the lamp base 4 to a substantially flat wall 14, namely on a horizontal ceiling 14. The fastening device 12 according to FIG. 1 is formed in the form of mounting holes 12 which pass through a flat wall 16 of the base housing 6. Through these holes 12 through the base housing 6 can then be screwed to the flat wall 14 by means of screws 18.

According to FIG. 6 the fastening device of two (from the two ends of the elongated base housing 6 'each equidistant - not shown in the illustrated perspective) resilient clips 12' (for example, sheet metal and / or plastic) is formed. The clips 12 'are screwed to the ceiling 14 by means of screws 18 in oblong holes (not shown) formed in the clips 12' and allow transverse orientation of the clips 12 '(in FIG FIG. 6 to the left and right) over the length of the slot. Grooves 17 are arranged laterally in the base housing, allowing the ends of the clasps 12 'to snap in a form-fitting manner. The grooves 17 are elongate (not shown in the illustrated perspective), which results in longitudinal alignment of the elongate base housing 6 '(in FIG FIG. 6 out of the plane of the drawing and into it). Such a fastening device 12 'has the advantage that the base housing 6' for this does not have to have a bore and that the problems associated with a bore problem with regard to tightness is avoided.

In particular, in order to access elements which are located in the base housing 6 (for example also the fastening bores 12 for the just mentioned screwing, but in particular the adjusting elements 40 of sensor functions, see later), the base housing 6 has a housing opening 19 (on which the Side 16 of the fastening device 12 opposite side 20), which is closed by a removably mounted cover 22.

That is, when placing the lid 22 and closing the base housing 6, the lamp 2 completes by simultaneous placement of the attachment housing 10 and thus of the luminous element attachment 8 (and at the same time fully sealed). Because the attachment housing 10 contains the lighting means (at least one LED board 24; FIGS. 4a and b ) of the luminaire 2 and has (again with reference to FIG FIG. 1 ) a translucent wall 26 on the lid 22 opposite side of the attachment housing 10.

In order to supply the lighting means with power, the base housing 6 has a connection passage 28, 28 'in one of its conversions, which is arranged, an electrical power supply line 30, namely a 230V line end 30, which comes out of the ceiling 14 for connecting a lamp 2 to lead into the base housing 6 into it. Simple and easy so can first (without the quite long and expansive and overall possibly more sensitive to shocks fixture 8), the lamp base 4 is still removed cover 10, 22 at the Screw the ceiling 14 tightly and then guide the cable end 30 into the interior of the base housing 6. This is according to FIG. 1 the connection passage 28 is arranged in the same flat wall 16. It is provided significantly larger than the diameter of the line end 30 to be performed, and the edge of the connection passage 28 is sealed with a circumferential rubber seal 32 with respect to the flat wall 14.

According to FIG. 3 For example, the terminal passage 28 '' is formed in a lateral transverse wall of the elongated base housing 6 '', circular, and a 230V terminal end 30 is inserted into the base housing 6 through a PG fitting 29 threaded into the terminal passage 28 '''' led into it.

In the base housing 6 is for the electrical supply of the LED boards 24 ( FIGS. 4a and b ) arranged an electrical illuminant supply device 34 which is adapted to connect the electrical supply voltage line 30 and the lighting means 24 (and is in electrical line connection 36 with a plug 38). The supply device 34 contains a transformer and an electronic circuit, at which the color temperature can be adjusted, namely at an adjusting device 40.

The illuminant supply device 34 also has a sensor circuit part 34. This has a microwave motion sensor (not shown) and a brightness sensor (with a sensor surface accessible through a bore in an outside wall of the base housing 6 for ambient light, not shown). The sensor circuit part is thus adapted to utilize movement in the distance (which can be set at the setting device 40) around the luminaire 2 as a trigger for switching on the luminous means. Also, when falling below a (adjustable at the setting device 40) limit of the brightness in the vicinity of the lamp 2, the lamp either to turn on a separate light switch (the line end 30 turns on or off, not shown) at all only release it (and this alternative is also selectable on the setting device 40) automatically switch on immediately. Also, it can automatically turn off the lamp 2 after a (adjustable at the setting device 40) time after switching on. These functions are, also on the entry device 40, individually on and off. In particular, for these different adjustabilities, it is advantageous that the base housing 6 has the cover 22. Because the so equipped light source supply device 34 is located in the base housing including the corresponding adjustment elements 40, the lid 22 can be opened again at any time after the initial installation of the lamp 2, and settings can be changed at any time subsequently.

In order to produce the electrical supply of the luminous means 24 before the cover 22 is placed on (in the interior of the luminaire base 4, which is closed later by placing the cover 22), the luminous element attachment also has a (second) connection element 42 which is set up for the (first) connection element 38 (the luminaire base) to connect and so bring the bulb 24 through the light-emitting lead 36 with the bulb supply device 34 in line connection. This second connection element 42 is located outside of the (in particular substantially moisture-tight) attachment housing 10 in order to be accessible for connection - but is, through a hole in the surface within the edge of the lid 22 therethrough ( FIG. 2 ), with the lamp 24 in the interior of the attachment housing 10 in electrical line connection 44: when the cover 22 is placed on the base housing 6, the second connection element 42 together with the line connection 44 thus disappears in the base housing 6 (FIG. FIG. 4a ).

The base housing has a forwarding passageway 46 in the form of an annular rupture line 46 that is configured to extend an electrical power supply line (particularly a 230V line) out of the base housing 6 respectively. This serves to connect another lamp (not shown) adjacent to which the base housing 6 belongs. This other lamp may be a luminaire according to the invention (and in turn have a forwarding passage so as to connect several lights according to the invention side by side). According to FIG. 3 For example, the relay passage 46 is formed in a lateral transverse wall of the elongated base housing 6 "(opposite the lateral transverse wall with the connection passage 28"), and a relaying 230V power supply line 47 is threaded through a PG fitting 29 screwed into the relay passage 46 , led out of the base housing 6 '' addition.

To connect a forwarding supply voltage line 47 (which is routed through the forwarding passage 46), the supply device 34 in the base housing 6 has a power supply output (a 230V output) 48 in electrical line connection with a power supply terminal (namely, a luster terminal) 50 , This is arranged in the base housing 6 in the region of the forwarding passage 46.

The base housing 6 is elongated (namely, a straight elongated cuboid box) having the one substantially planar elongate wall 16 which is adapted to abut, when attached by the fastener 12, to a substantially planar wall 14.

The housing opening 19 on the base housing 6 has an edge 20 which lies in a plane which is parallel to the flat wall 16. Thus, then the cover 22 as a wall element of the attachment housing 8 is flat and parallel to the flat wall 16 at which the Lamp 2 is to be mounted on the room wall 14.

Thus, the attachment housing 8 is elongate and in the same direction as the lid 22nd

In addition, the lid 22 is exactly in the middle of the elongated extent of the rear side (not translucent) wall 52 of the attachment housing integrated - namely in the wall 52 which is opposite to the translucent wall 26 of the attachment housing 8.

The luminaire 2 according to the FIGS. 1 to 4 is part of a system of luminaires or, in other words, a modular system for a luminaire described so far, in which a plurality of luminous body attachments 81 to 83 of different dimensions have the lid, so that the different luminaire attachments can be replaceably attached to the luminaire base. So can according to FIG. 5 on the same luminaire base, which is already mounted in a wall, subsequently not only (for example, used, soiled or damaged) lighting fixtures are exchanged for the same luminaire attachments, but in such a system according to the invention, the light can also be subsequently adapted, for example, to changing requirements for example regarding brightness, color temperature, reflector geometry or size of the luminaire attachment. Pictured in FIG. 5 are four different long elongated filament attachments 8, 81, 82, 83, which are attached to the same lamp base 4.

In FIGS. 4a and b It can be seen that the LED boards 24 (shown schematically, like all figures, in the attachment housing 8, for example, are formed as a board extending over the entire cross section of the body attachment, as in FIG FIG. 4b indicated, or, for example, as two at an angle of, for example, greater than 90 ° to each other arranged boards, as in FIG. 4a indicated.

The fastening of the luminous element attachment 8 on the luminaire base 4 takes place in the illustrated examples by means of four resilient snap clips 54 which snap into the grooves 56 on the attachment housing 10 fixed to the base housing 6.
