Description

The invention relates according to a first aspect of a lamp with a cover for covering an inner region of the lamp from above, wherein the cover is arranged such that it is reciprocally movable between a covering position and an open position, the inner area accessible from above when the cover member is in the open position and the inside portion is covered when the cover member is in the cover position.

By means of a corresponding cover element, it is possible to prevent dust or the like from entering the interior of the luminaire from above and possibly causing an undesired effect there by interaction with luminaire components, for example damage or failure of the luminaire.

Such a lamp is from the document DE 10 2006 018 255 A1 known. The cover is mounted pivotably about a horizontal axis on the lamp housing. When the cover member is in the open position, a fluorescent tube located in the interior can be exchanged from above. In the case of a comparatively large lamp, for example, a hall ceiling light, however, such a pivotable mounting of the cover requires a considerable effort due to the size and weight ratios; In addition, the handling of the cover when opening and closing the interior is particularly cumbersome.

The invention has for its object to provide a lamp with a corresponding cover, which is improved with respect to manufacture and handling - especially in the case of a particularly large and / or heavy light.

This object is achieved according to the invention with the lamp mentioned in claim 1. Particular embodiments of the invention are specified in the dependent of claim 1 claims.

According to the first aspect of the invention, there is provided a luminaire having a cover member for covering an inner portion of the luminaire from above, wherein the cover member is disposed so as to be reciprocally movable between a cover position and an open position, the inner portion accessible from above, when the cover member is in the open position and wherein the interior is covered when the cover member is in the covering position. The luminaire furthermore has a rail element for the displaceable mounting of the cover element between the covering position and the opening position.

With the rail element, movement of the cover element between the covering position and the opening position can be carried out particularly easily; This is particularly noticeable in the case of a comparatively large lamp with a correspondingly large cover advantageously. It can be achieved with the cover element that removal of a cover is not required for access to the interior of the luminaire, for example for replacement of an operating device or for maintenance work; It must also be kept no cover or put aside. This is with respect to the safety in handling the lamp as well as for the handling itself of great advantage.

Preferably, the lamp is designed such that the cover between the covering and the open position is mounted horizontally on or in the rail element slidably. A corresponding horizontal displacement of the cover requires no, at least no significant lifting work and thus very little effort.

Preferably, the cover is viewed from above at least in a first approximation U-shaped. In this embodiment can be arranged in the space formed by the two U-legs - at least partially - for example, an upward-facing light exit opening of the lamp for generating an indirect lighting. Thus, a comparatively compact or space-saving design of the lamp is possible.

Preferably, the luminaire further comprises a further cover element and a further rail element, wherein the further rail element serves for displaceable mounting of the further cover element; In this case, the further cover element is viewed from above with respect to a central region of the lamp the first-mentioned cover disposed opposite. The additional cover element makes it possible to achieve that the cover element has to be moved far less for a specific opening of the interior of the luminaire; This allows a better weight distribution in the open state.

Preferably, the luminaire further comprises a support frame for placement from above on a horizontal support in such a way that a first part of the support frame projects on a first side of the support and a second part of the support frame protrudes on a second side of the support opposite the first side, where the light is formed such that the cover member between the covering position and the opening position is slidably mounted on or in the rail member parallel to the carrier. This allows a balanced weight distribution of the lamp during a movement of the cover. In this case, the lamp is further designed such that the cover is so displaceably mounted between the covering position and the opening position, that during a movement of the cover between the covering position and the opening position of the center of gravity of the cover is always above the carrier. This makes it possible to achieve a particularly balanced weight distribution.

The cover and the further cover are further advantageously mirror-symmetrical and mirror-symmetrically mounted.

According to a second aspect, the invention relates to a luminaire with a module for generating a direct illumination.

It is known to mount such a light on a ceiling by means of known fastening means, such as screws. In the case of a particularly large and / or heavy luminaire, such an attachment is complicated and cumbersome to handle.

The invention has the further object of specifying a lamp with a module for generating a direct lighting, which offers improved possibilities with respect to the assembly - especially in the case of a particularly large light.

This object is achieved according to the invention with the lamp mentioned in claim 8. Particular embodiments of the invention are specified in the dependent of claim 8 claims.

According to the second aspect of the invention, there is provided a luminaire having a module for generating direct illumination; In addition, the lamp has a support frame for placement from above on a horizontal support and a holding means for holding the module to the support frame. In this case, the holding means is designed and movable back and forth between a mounting position and a holding position arranged on the module, that the module for mounting the lamp can be moved from below into the relative position provided for the operation relative to the rest of the lamp when the holding means is in the mounting position and the holding means in the holding position can hold the module to the support frame.

Such designed holding means simplifies the assembly considerably. This advantage is all the more serious, the bigger and heavier the lamp is. For example, the luminaire may be a luminaire for a hall that is intended to be installed at high altitude, for example, higher than 10 meters or higher than 20 meters above the floor of the hall. Here it is particularly important that an assembly is possible in which the module must be kept as short as possible manually or otherwise. With the said holding means, the module, after it has been moved for mounting from below in the intended position relative to the remaining lamp, only be held until the holding means has been moved from the mounting position to the holding position. Thereafter, the module is held by the holding means on the support frame and no longer needs to be supported otherwise.

In this case, the holding means preferably has a support element with a support surface, which is designed to rest on the support frame from above. As a result, it is possible during assembly of the module to the support frame that the module is held by the holding means on the support frame after a very short time and very reliable.

Preferably, the holding means on a mounting bracket, which is pivotable about an axis, in particular pivotable about a horizontal axis, is arranged on the module. A corresponding pivoting movement can be carried out particularly easily and quickly during assembly. It is particularly advantageous if the holding means also has a further mounting bracket, which is designed mirror-symmetrically to the first-mentioned mounting bracket. Two such mounting brackets are particularly well suited for holding the module to the support frame.

Advantageously securing means are arranged on the support frame, which serve to secure the holding means in the holding position. This makes it possible to achieve a particularly secure hold of the module. The securing means may comprise screws, for example.

Preferably, the lamp further comprises means for fixing the support frame to the horizontal support. As a result, a particularly secure mounting of the lamp is possible.

Preferably, the lamp also has a further module for generating a direct illumination, wherein the support frame is designed for placement from above on the horizontal support, that a first part of the support frame projects on a first side of the support and a second part of the support frame on a second, the projecting from the first side opposite side of the support and wherein the first-mentioned module is mounted from below to the first part of the support frame and the further module is mounted from below to the second part of the support frame. The fact that in the intended for the operation of the position of the lamp relative to the horizontal support, the two modules are arranged on two opposite sides of the carrier, it is possible that the support frame of the lamp is supported by the support such that no fastening means for fastening the Luminaire are required, which capture the entire weight of the lamp; It suffice securing means for securing the lamp in the intended relative position to the horizontal support. Thus, a much simpler and safer installation is possible.

Preferably, the luminaire further comprises a further holding means, which is designed to hold the further module to the support frame, wherein the further holding means in those features, which are mentioned above with respect to the first-mentioned holding means coincides with the latter. This allows in particular a particularly simple and safe installation of a comparatively large and heavy light.

1 shows a view of an embodiment of a lamp according to the invention obliquely from above The lamp may be in particular a comparatively large and / or heavy lamp, in which the problem of mounting due to the size or severity in general is considerable. In particular, it may be a ceiling light, for example, to illuminate a hall.

For example, the luminaire may have a horizontal diameter of more than 1 meter or even more than 2 meters. For example, the luminaire may be designed to be mounted in a large hall at a comparatively great height, for example in more than 10 meters or more than 20 meters above the floor of the hall.

The luminaire may be provided for on a horizontal support 12 to be mounted, which is mounted at the appropriate height in the hall as a construction element. In 1 is the carrier 12 only partially shown, especially in truncated condition. It can also be provided that the lamp also on another horizontal support 12 ' is mounted, which is perpendicular to the first-mentioned carrier 12 and at the same height as the latter. Also the additional carriers 12 ' is in 1 shown only cut.

The luminaire may be provided for, on the one hand, to emit light for the purpose of producing a direct illumination downwards and, on the other hand, to raise another light to produce an indirect illumination.

2 shows one of the 1 corresponding view from diagonally below. Immediately adjacent to the two horizontal beams 12 . 12 ' four modules can be seen, which can be provided for the production of direct lighting or short direct lighting.

As turn out 1 can be seen by way of example, the lamp has a cover 2 on, which is intended to cover an interior of the lamp from above. 3 shows a corresponding view with the cover open 2 and 4 a corresponding view in which the cover is removed from the lamp. The cover element 2 can also serve as protection against contact.

The cover element 2 is arranged so as to be reciprocally movable between a covering position and an opening position. In 1 is the cover element 2 shown in the covering position, in 3 in the open position. When the cover element 2 in the open position, the corresponding interior of the lamp is accessible from above. For example, it can be provided that in the interior of a light source and / or a resource of the lamp are arranged and, when the cover 2 is located in the open position, the interior is accessible from above so that, for example, a commissioning of the lamp, a replacement of a control gear, a maintenance work on the light or the like can be performed. When the cover element 2 is in the covering position, the interior area is covered. The cover element 2 fulfills the function of a hood in this sense.

The cover element 2 can be made of metal, for example.

Furthermore, the lamp has a rail element 4 for displaceable mounting of the cover 2 between the covering position and the opening position. The term "rail element" may be two rail parts 41 . 42 include, which are arranged parallel to each other. The rail element 4 may in particular be arranged and designed such that the cover 2 in the sense of a "full statement", so according to the representation of 3 ,

By said embodiment is achieved that in a corresponding work in the interior of the lamp no cover removed, kept and set aside. This is particularly advantageous in terms of safety and ease of installation.

Preferably, the lamp is designed such that the cover 2 between the covering position and the opening position horizontally on or in the rail member 4 is slidably mounted. Only a horizontal movement avoids the cover element 2 must be raised significantly. In addition, this can be achieved that the cover 2 can maintain its position both in the covering position, as well as in the open position without further action. This further facilitates the assembly or other work.

8th shows the light from above. As can be seen from this drawing, the cover 2 Seen from above, at least to a first approximation, be U-shaped. In this embodiment can be in the space formed by the two corresponding U-legs space - at least partially - for example, an upward-facing light exit opening 50 arrange the luminaire to produce the indirect lighting. Thus, a comparatively compact or space-saving design of the lamp is possible. As in the 8th . 1 . 3 and the exploded view of 5 shown, the lamp can also be another cover 6 and another rail element 8th have, wherein the further rail element 8th for displaceable mounting of the further cover element 6 is trained. The further cover element is advantageous here 6 viewed from above with respect to a central region of the lamp - for example with respect to the light exit opening 50 - The first-mentioned cover 2 arranged opposite. This allows a particularly compact distribution.

Preferably, the luminaire also has a, for example, in the 4 and 5 designated, supporting frame 10 on top, to be put on top of the horizontal support 12 is designed. In addition, the support frame 10 in 13 shown in separated form. The supporting frame 10 can be made of aluminum, for example.

The supporting frame 10 is designed so that it is suitable for the wearer 12 to be set up that a first part 14 of the supporting frame 10 on a first side of the carrier 12 survives and a second part 16 of the supporting frame 10 on a second side of the carrier 12 opposite the first page. With reference to the representations of 4 and 5 is the first part 14 on the side of the wearer facing the observer 12 arranged and the second part 16 on the side facing away from the viewer of the wearer 12 ,

Advantageously, the lamp is designed such that the cover 2 between the covering position and the opening position on or in the rail member 4 parallel to the carrier 12 is slidably mounted. This avoids that the weight of the lamp during a movement of the cover 2 unfavorable with respect to the longitudinal axis of the carrier 12 is relocated. Like, for example 4 shows, this are the rail parts 41 . 42 of the rail element 4 parallel to the carrier 12 arranged.

Particularly advantageous with respect to the weight ratios, it is when the lamp is designed such that the cover 2 is mounted displaceably between the covering position and the opening position such that during a movement of the cover 2 between the covering position and the opening position, the center of gravity of the cover member 2 always above the carrier 12 located. In the embodiment shown, this is effected by the fact that the cover 2 and the rail element 4 symmetrical to the longitudinal axis of the carrier 12 are formed.

As in the embodiment shown, the case, in particular, the cover 2 and the other cover 6 be formed mirror-symmetrically and mirror-symmetrically displaceable. The mirror symmetry is formed in particular with respect to a plane which is oriented normal to the longitudinal axis of the carrier and, for example, through the center of the further carrier 12 ' runs.

The 9 . 10 and 11 show for further illustration three sectional views through the lamp, according to the in 8th designated sections AA ( 9 ), BB ( 10 ) and CC ( 11 ).

In the following, the second aspect of the invention will be discussed. The features described so far can also be advantageously realized in a luminaire according to this second aspect.

The lamp has an example in 4 designated module 20 for generating a direct illumination. In the 14a and 14b is the module 20 shown separately in perspective view and in the 15a and 15b in two sectional views.

Furthermore, the lamp has the support frame already described 10 for placing on top of the horizontal support 12 or on the horizontal beams 12 . 12 ' on.

Furthermore, the lamp, for example, in the 4 . 5 . 14a and 14b designated holding means 22 on that to hold the module 20 on the support frame 10 is trained. The holding means 22 is between one - exemplified in 14a shown - mounting position and a - example in 14b shown holding position back and forth on the module 20 arranged. The arrangement is such that the module 20 can be moved from below for mounting the lamp in the intended for operation relative position to the rest of the lamp, when the retaining means 22 located in the mounting position. When the holding means 22 is in the holding position, the retaining means 22 the module 20 on the support frame 10 hold.

Preferably, the support frame 10 an opening, for example of rectangular or square shape, which in shape to the module 20 is adjusted so that the module 20 can be moved from below into the opening for mounting and then the holding means 22 as intended can be moved from the mounting position to the holding position, thereby subsequently the module 20 on the support frame 10 hanging by the holding means 22 is held.

Such as from the 14b and 6 As can be seen, the retaining means 22 a support element 24 having a support surface which is for support from above the support frame 10 is provided or designed. With such a bearing surface can be in the attachment of the module 20 on the support frame 10 very easy and fast a secure hold of the module 20 on the (horizontally oriented) support frame 10 produce.

The holding means 22 in particular, a mounting bracket 30 include a - in 14a designated axis A pivoted to the module 20 is arranged. Preferably, the axis A is formed such that it runs horizontally in the operating state of the lamp. The mounting bracket 30 can then in the mounting position of the holding means 22 Be "folded" and in the in 14b shown holding position "unfolded".

A particularly secure hold of the module 20 can be achieved if the holding means 22 also has another corresponding mounting bracket 32 has, which is symmetrical with respect to the first-mentioned mounting bracket 30 trained and pivotable on the module 20 is arranged.

Such as in the 7 and 13 hinted at, the support frame 10 securing means 34 having, for securing the holding means 22 are formed in the holding position or serve. These securing means 34 can include screws, for example; Particularly advantageous are the screws before mounting the lamp to the support frame 10 already pre-assembled.

As in the 6 and 13 by way of example, the luminaire may also comprise means 36 for fixing the support frame 10 on the horizontal support 12 or on the horizontal supports 12 . 12 ' exhibit. These may include, for example, a fastening tab.

Like, for example 5 can be seen and mentioned above, the lamp can also be another module 26 for generating a direct illumination, wherein the support frame 10 for placing on top of the horizontal support 12 is formed such that a first part 14 of the supporting frame 10 on a first side of the carrier 12 survives and a second part 16 of the supporting frame 10 on a second side of the carrier opposite the first side 10 survives, then continue the first-mentioned module 20 from the bottom of the first part 14 of the supporting frame 10 is mounted or attached and the other module 26 from the bottom of the second part 16 , This allows such an advantageous weight distribution of the lamp with respect to the carrier 12 in that the luminaire has no attachment means or no external force - solely by the support on the support 12 - In its intended for operation position relative to the carrier 12 can remain. Thus, no fasteners are required to support the lamp, which can carry the weight of the lamp. In any case, it is sufficient, appropriate securing means such as the above-mentioned means 36 to provide for securing or fixing the positioning of the lamp.

The light can be - for example in 5 designated - further holding means 38 having, for holding the further module 26 is formed, wherein the further retaining means 38 in those features which are described above with respect to the first-mentioned holding means 22 named in accordance with the latter.

How out 5 Furthermore, it can be seen, the lamp may also have two more modules for direct lighting, so a total of four modules, these modules are preferably formed analog or identical. If the given support structure the said horizontal support 12 and at right angles extending further horizontal support 12 ' has, the lamp can be advantageously designed such that the support frame 10 from above to the crossing point of said carrier 12 . 12 ' is placed and one module each from a neighboring module of the carrier 12 or the other carrier 12 ' is disconnected. This arrangement is also in 12 shown, which shows a view of the lamp from below.

The supporting frame 10 can - as with respect to the former module 20 described - for each of the modules have a corresponding opening into which the respective module for mounting can be moved from below.

The module 20 can - as well as the other modules - include a radiator unit, for example, comprises two light sources, for example, with a power of 400 W. Preferably, the two bulbs differ with respect to the color temperature of each light generated by them. For example, the first light source may be provided for emitting light having a higher color temperature for daylighting, and the second of the two bulbs for outputting light having a lower color temperature for lighting the remainder of the day. The first lighting means may be formed, for example, to produce one light with the light color 840, and the second light source may be formed with the light color 830 to produce a light.

A circuit of the modules can be provided via a relay. Preferably, it is provided that in the change from one type of lighting to another type of lighting by means of modules, ie example of the lighting during the day to the lighting for the rest of the day, not all modules are switched simultaneously, but in chronological order in succession, for example at intervals of one minute or a few minutes. In this way, it is ensured that at any time during the change of the lighting mode, the lamp does not emit any light over the modules. In particular, this makes it possible to achieve a particularly pleasant, sliding transition of the two types of illumination concerned.

The module 20 or each of the modules can - as in the 5 and 14b denotes - furthermore a removable lid 44 preferably having a handle 46 includes. The lid 44 is placed from the top to the rest of the module and can with the help of the handle 46 be removed in a simple manner. On the lid 44 a head reflector of the relevant module can be arranged. Below the lid 44 can be arranged in the module, a reflector, in particular a reflector which is designed in a special way to account for a large mounting height, for example 28 meters, the lamp.

Furthermore, on the lid 44 a socket for a holder and electrical contacting of a light source or the lighting means be arranged. In particular, the lid can 44 accordingly via a power supply line with a corresponding, for example in 7 designated, operating device 48 be connected. The power supply line may have a plug contact for disconnection and connection. By removing the lid 44 the bulbs are easily accessible, for example, for an exchange.

Such as from the 3 and 4 shows, the lamp can continue to be a light-emitting element 52 for generating an indirect illumination by an upward light emission. The already mentioned light exit opening 50 may be part of the light-emitting element 52 represent and accordingly as a light exit opening of the light-emitting element 52 be educated. The 16a and 16b show two perspective views of the light-emitting element 52 , the 18a and 18b two sectional views of the same.

The light-emitting element 52 may comprise two bulbs, preferably two bulbs, the - analogous to the bulbs of the module 20 - May emit light in two different light colors, so for example, turn 830 and 840. The two bulbs, for example, each have a power of 150W. A control via a relay can be provided, in particular analogous to the circuit of the module 20 to switch between a lighting at higher color temperature or light color during the day and a lighting at lower color temperature or light color for the rest of the day.

The light-emitting element 52 can - as from the 8th and 4 emerges - viewed from above centrally in the lamp or on the support frame 10 arranged to be bolted to the latter, for example. The light-emitting element 52 may be a hinged, preferably translucent cover 54 have, that the light exit opening 52 can cover. 16a shows the light-emitting element 52 with closed cover 54 . 16b with the cover open 54 , 17 shows a view from above of the light-emitting element 52 with the cover removed 54 ,

The light-emitting element 52 may comprise a housing made of sheet metal, preferably a dust-proof housing or a housing which corresponds to the degree of protection IP54.

The light-emitting element 52 can be designed so that when the cover is open 54 a change of the two bulbs and / or an electrical connection of the two bulbs is possible.

A lower area of the light-emitting element 52 can be designed to hold an electronics of the lamp. For example, controls for controlling the modules can be arranged here.

Operating devices, such as the mentioned operating device 48 , for the bulbs of the modules can be arranged in a space between the modules. Preferably, the arrangement is such that the cover 2 and the other cover 6 together with the cover 54 the light emitting element 52 Cover all electrical components of the luminaire from above. The lamp may preferably be designed so that all necessary electrical equipment can be pre-assembled on equipment boxes, which then need to be used and infected on site.

As in the 3 and 12 As shown, the luminaire may further comprise an emergency illuminant, for example in the form of a plurality of LEDs 60 , For example, at each of the modules depending on such an LED 60 be arranged, and that for emitting light down. The LED 60 can in particular outside of a corresponding downwardly directed light exit opening 62 be arranged of the relevant module. As a result, emergency lighting can be ensured in the event of an emergency, for example in the event of a power failure.

The LEDs 60 can each be provided with a lens and be mounted as a "quad package" on a sufficiently sized heat sink, which is attached to the modules. This can be like in 15a be implied, realized. Furthermore, then a translucent disk, for example a glass pane, can be arranged so that they both the LED 60 a module, as well as the light exit opening 62 of the module concerned from below.
