Description

The invention relates to a wet room light with a housing, an electrical lamp and a translucent cover, wherein in the housing, a passage opening for a power cable to power the illuminant is formed.

In the case of a damp-proof luminaire, the individual components should be shielded from the outside environment as well as possible; in particular, the penetration of moisture should be prevented.

A wet room light is usually a total of elongated and has a housing and a, usually downwardly facing, translucent cover which is circumferentially sealingly connected to the housing. In the enclosed by the housing on the one hand and the cover on the other hand, the interior of the wet room light is an electric light source, and usually held on the underside of a, substantially plate-shaped support member. An operating device for the lighting means is arranged on top of the carrier element.

For the electrical power supply of the lamp, a power cable coming from the outside is guided through a through-hole formed in the housing through the opening into the interior and there by means of a terminal which is also located on top of the support member, connected to an electrical conductor, on the other hand on leads to the operating device.

To make the electrical connection between the power cable and the lighting means can - for example, after the housing has been attached to a ceiling - the cover are removed and the support member are released from its position, so that said terminal is accessible. The handling here, however, requires relatively high effort.

To avoid this, it is known in the art to use a lamp terminal carriage. This is based on the sketches in the FIGS. 5 and 6 explained in more detail. In Fig. 5 Such a light fitting carriage 206 is outlined as such, in FIG Fig. 6 One recognizes an end region of an elongate moisture-proof light with a housing 200 and a cover 202 in conjunction with the lamp connection carriage 206. A power cable 208 is guided through a through-opening 204 formed in the housing 200 into the interior of the moisture-proof lamp, with the aid of the This is a total of elongated and electrically connected at a first end portion 210 by means of an integrated terminal with an operating device located in the interior; at the other end region 212, the power cable 208 is passed through a rubber grommet 214 and a screw connection for sealing connection with the housing 200 is formed. After the electrical connection has been made, the luminaire connection carriage 206 - as in FIG Fig. 6 indicated by an arrow P - pushed with the first end portion 210 first through the through hole 204 and further sealed by means of the screw on the second end portion 212 and by means of an O-ring, the through hole 204.

However, the handling of the lamp connection slide is not without problems and comparatively expensive; Moreover, the lamp connection slide is a comparatively complex component. In particular, it should be remembered that in order to produce the moisture-proof luminaire, the integrated terminal of the luminaire connection carriage must first be connected to the corresponding electrical conductors which continue internally in the moisture-proof luminaire; This operation is usually carried out by the manufacturer of the moisture-proof light, so that an end-user can connect to the power cable without having to remove the cover from the housing. Due to this configuration, an automated wiring to the integrated terminal of the lamp terminal carriage is practically impossible.

From the US 5,154,507 a luminaire with a housing and a translucent cover is known. In the housing, a passage opening for a power cable is formed, which is guided to a terminal. The housing has an access opening, under the use of which the power cable can be connected to the terminal.

From the DE 86 12 314 U1 is a wet room lamp with a designed as a profile tube lamp carrier known. In the profile tube, an opening is formed, behind which there is an assembly chamber.

The invention has for its object to provide a corresponding improved wet room light. In particular, the wet room light should facilitate the production of electrical power.

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

According to the invention, a wet room light is provided, which has a housing and a transparent cover, which is supported on the housing such that an interior of the wet room lamp is formed or circumscribed by the housing and the cover. In the interior, an electric lamp is arranged, wherein in the housing, a passage opening for a power cable for powering the lamp is formed. Furthermore, in the interior, an electrical connection element for electrically connecting the power cable with at least one electrical conductor for powering the light source is arranged. The housing also has an access opening formed such that the connector can be electrically connected using the access port to the power cable.

In this way, no separate part, such as the light fitting carriage described above, is required for the production of the electrical connection. The connecting element can be firmly attached to a further lighting component, so that in particular an automated wiring of the connecting element is well possible. In this way, the production cost of the moisture-reducing beacon can be reduced. As a connecting element, a standard terminal can be used, which is a simpler component compared to the lamp terminal slide.

When using the known lamp terminal slide is given due to the usual size ratios, a certain upper limit for the number of electrical conductors, which is in the prior art at three. Therefore, through-looping, emergency lighting control, dimming etc. is not possible. By contrast, the solution according to the invention also makes it possible to handle well a connecting element for more than three conductors; For example, this can be a standard terminal with a corresponding number of connection points - for example, a least seven-pin terminal - are used. The possibilities of electrical control of the moisture-proof light are therefore significantly improved. On site, for example, no more junction boxes are required for several corresponding damp-proof lights. In addition, both flexible and rigid conductors can be used.

According to the invention the wet room lamp further comprises a support member, in particular a support plate, wherein the connecting element is arranged fixed on the support member. In this way, automatic wiring is particularly well possible.

According to the invention, the moisture-proof luminaire is designed in such a way that the support component can be reversibly bent out of an operating state provided for operation of the moisture-proof lamp into a bent state, wherein the connecting element is closer to the access opening in the bent state than in the operating state. In this way, the accessibility to the connecting element through the access opening can be further improved, so that the handling in the manufacture of the electrical connection is further facilitated. For this purpose, the carrier component advantageously has a desired bending line for a bend from the operating state to the bent state. As a result, the bend is particularly easy to carry out.

The moisture-proof luminaire is preferably configured in such a way that the connecting element is positioned in the bent state of the carrier component so that it passes through the access opening. This allows a particularly good accessibility to the connecting element.

A particularly good accessibility to the connecting element can also be achieved when the wet room lamp is designed such that the edge of the access opening is at least substantially in one plane, and the connecting element is disposed within the - with respect to this plane - normal projection of the access opening , This makes it possible to achieve that the connecting element can be moved particularly far by bending the carrier component, in principle even through the access opening.

Preferably, the wet room light is configured such that the edge of the access opening lies at least substantially in one plane and the edge of the passage opening lies at least substantially in a further plane, wherein the further plane intersects the first-mentioned plane at an angle which is greater than 45 °, preferably greater than 55 °. In this way it can be achieved that the power cable for the production of the electrical connection with good accessibility to the connecting element must be bent very little.

The wet room lamp preferably has an overall elongated shape, wherein the access opening is formed on one of the two, given by the elongated shape end portions of the wet room lamp. Also, the access opening preferably has an elongated shape, wherein preferably the longitudinal extension of the moisture-proof lamp and the longitudinal extension of the access opening are oriented parallel. As a result, a particularly good accessibility is possible with a generally slim shape of the wet room light.

Further advantageously, the access opening is formed at a location in the housing opposite to the cover.

A particularly good accessibility is further made possible if the size of the access opening is greater than the size of the passage opening, preferably larger than three times the size of the passage opening.

For sealing closure of the access opening, the moisture-proof light advantageously has a lid.

In Fig. 1 is a view of a part of an end portion of a moisture lamp according to the invention sketched. The moisture-proof light is generally elongated and extends along a main axis S.

The wet room lamp has a housing 2, as well as a translucent cover 4, which is sealed to the housing 2 in a conventional manner, in particular moisture-proof, wherein formed by the housing 2 and the cover 4, an interior of the moisture lamp is or circumscribed. The cover 4 is supported on the housing 2, for example, by a plurality of (in Fig. 1 not shown) bracket-like holding means.

In the housing 2, an access opening 6 is formed, which is closed during operation of the moisture lamp by a (not shown in the figures) sealing lid. In Fig. 1 the wet room light is sketched without the lid, so that through the access opening 6 through a part of the interior of the wet room light can be seen.

In the interior of the wet room lamp, an electric light source is arranged, for example in the form of at least one fluorescent tube. One of the bulbs generated light can leave the interior through the translucent cover 4 through to the outside.

For the operation of the moisture lamp an orientation of the same is provided, in which the housing 2 faces up and the cover 4 and thus the light output to the bottom. In the following description, this orientation is assumed. In general, however, a different orientation may be provided; the directions are to be reinterpreted accordingly in this case.

In Fig. 2 the housing 2 is sketched in separated form. For attachment to a ceiling, the housing 2 may have special attack elements 9 on its upper side.

Furthermore, the housing 2 has a passage opening 8, which is designed or designed for a current feedthrough for the power supply of the luminous means. In the FIGS. 3A to 3E sketches are shown on several steps in the production of the electrical power supply. The work steps will be described in more detail below. In Fig. 3E a state is shown in which a power cable 10 for powering the bulb by the (here compared to Fig. 1 formed at another location) through opening 8 is guided. For sealing the passage opening 8, a rubber grommet 5 or a similar sealing means may be provided, which causes a seal between the lateral surface of the power cable 10 and the edge of the passage opening 8.

Furthermore, the wet room lamp has an arranged in the interior electrical connection element 12 for electrically connecting the power cable 10 with at least one, by way of example in Fig. 3E designated, electrical conductor 14 for powering the bulb. The connecting element 12 may in particular be a terminal. The clamp may have several poles, for example more than three, preferably more than five, more preferably at least seven. The at least one electrical conductor 14 is also in the illustration of Fig. 4 can be seen, which shows a view through the access opening 6 from a further perspective. As continues in Fig. 4 exemplified, can the at least one electrical conductor 14 form an electrical connection to an operating device 7 of the moisture-proof light, which serves to operate the lighting means.

The access opening 6 is formed such that the connecting element 12 can be electrically connected to the power cable 10 using the access opening 6. As in particular from Fig. 1 shows, the access opening 6 is designed so large that this allows good accessibility to the connecting element 12 from the outside. The access opening 6 may, for example, have a width B running transversely to the main axis S of the moisture-proof luminaire, which width is at least 3 cm, preferably at least 5 cm, more preferably at least 7 cm. The access opening 6 may, for example, have a length L running parallel to the main axis S of the moisture-proof luminaire, which length is at least 3 cm, preferably at least 5 cm, more preferably at least 7 cm. As will be explained below, the shape of the access opening 6 is preferably oblong overall, so that the following applies to the relationship between L and B :
L> B.

As from the sketches of FIGS. 3A to 3E clearly shows, can be electrically connected by this configuration using the access opening 6, the connecting element 12 with the power cable 10. In particular, it is not necessary for the preparation of this electrical connection to release the cover 4 of the housing 2. As a result, the handling in the manufacture of the electrical power supply is facilitated.

Advantageously, the wet room light also, exemplary in Fig. 1 designated, support member 16, in particular in the form of a support plate, wherein the connecting element 12 is arranged fixed on the support member 16. The carrier plate is preferably designed such that it subdivides the interior of the moist space lamp into an upper interior area and into a lower interior area, wherein the illuminant is arranged in the lower interior area and the connecting element 12 is preferably arranged in the upper interior area. In particular, the operating device 7 may be arranged in the upper interior region.

Preferably, the connecting element 12 is arranged fixed directly on the support plate 16. By a correspondingly fixed arrangement, it can be achieved that the electrical connection of the at least one electrical conductor 14 to the connecting element 12 is comparatively easily possible in an automated form, for example by means of a robot for automatic wiring.

Advantageously, a reflector for the light emitted by the light source is arranged on the carrier component 16. The support member 16 may also be formed as a corresponding reflector itself.

In Fig. 1 the carrier component 16 is shown in an operating state intended for operation of the moisture-proof light, that is to say for light emission, and likewise in the FIGS. 3A and 3E , Preferably, the moisture-proof light is designed such that the support member 16 can be reversibly bent out of this operating state into a bent state, which is exemplified in the FIGS. 3B . 3C and 3D is sketched, in such a way that the connecting element 12 is in the bent state - compared to the operating state - closer to the access opening 6. In this way, the accessibility to the connecting element 12 can be further improved for the production of the power connection.

The support member 16 is particularly easy to move from the operating state in the bent state, if one, exemplary in Fig. 3A suggestively recognizable - intended bending line 18 for the bend has. For example, the support member 16 may be a stamped part, for example made of sheet metal, wherein the desired bending line 18 is formed by a weakening of the material.

To produce the power supply, for example, as based on the FIGS. 3A to 3E be outlined. In a first, in Fig. 3A sketched sequence state, the support member 16 is in the operating state. The fixedly fixed on the support member 16 connecting element 12 is already electrically connected to the at least one further conductor 14, on the other hand to the (here hidden from the housing 2) operating device 7 continues.

In a second, in Fig. 3B shown sequence state, the support member 16 has been placed in the bent state; For example, it can be provided that the access opening 6 is dimensioned so that the support member 16 can be brought under manual access of the access opening 6 from the operating state in the bent state, preferably without tools.

As if from a comparison of FIGS. 3A and 3B As can be seen clearly, the connecting element 12 is better accessible in the bent state of the carrier component 16 than in the operating state of the carrier component 16 Fig. 3B Suggestively exemplified, the embodiment is preferably such that the connecting element 12 in the bent state of the support member 16, the access opening 6 is positioned by passing.

In Fig. 3B Furthermore, the holding elements already mentioned above are provided with the reference numeral 3, which serve to hold the cover 4 on the housing 2.

In a third, in Fig. 3C shown sequence state, the power cable 10 is pulled through the through hole 8 and in a fourth, in Fig. 3D sketched sequence state, the power cable 10 is electrically connected to the connecting element 12.

After the electrical connection has been made, the carrier component 16 is again moved from the bent state back into the operating state. Optionally, the power cable 10 may still be displaced longitudinally through the passage opening 8 until it is brought into a desired position. This way, a fifth, in Fig. 3E sketched sequence state reached.

The access opening 6 is preferably designed so that the edge of the access opening 6 is at least substantially in one plane. By "substantially" is meant that a plane can be found, of which the edge at no point has a distance which is greater than a small amount, the small dimension given for example by 10% of the maximum internal extent of the access opening 6 can be. In the example shown, the access opening is located 6 essentially in a horizontal plane. The access opening 6 is formed here within an upwardly facing ceiling wall of the housing 2.

The connecting element 12 is arranged within the - with respect to the plane - normal projection of the access opening 6. This makes it possible for the connecting element 12, which is fixed on the carrier component 16, to basically move into the access opening 6 by bending the carrier component 16 so that it passes through the access opening 6-and in principle even beyond it to the outside.

How out Fig. 1 Furthermore, by way of example, the passage opening 8 can lie at least substantially in a further plane, for example in a substantially vertical plane. The term "substantially" is hereby understood as above in connection with the access opening 6. In the case of an elongated moisture-proof luminaire, the passage opening 8 may be formed in particular in an end wall of the housing 2. If the two planes in which the access opening 6 and the passage opening 8 are located, enclose an angle with each other which is greater than 45 ° or, even better, greater than 55 °, for example between 75 ° and 90 °, the power cable 10 must be manufactured the electrical connection are bent only comparatively little.

If the wet room lamp is elongated overall, the access opening 6 can be designed to save space at one end of the wet room lamp. In addition, in practice it is often provided in this case to arrange a plurality of corresponding moisture-proof luminaires lengthwise in a row so that comparatively short connecting paths can be achieved by forming the access opening 6 at the end region between two adjacent wet-room luminaires. Therefore, the damp-proof luminaire is particularly preferably designed such that it has a further access opening at the opposite end region, which is designed analogously to the first-mentioned access opening 6, and preferably a further through-opening which is designed analogously to the first-mentioned through-opening 8.

A good bending possibility with a comparatively space-saving design can be achieved if the access opening 6 has an elongate shape; In particular, the longitudinal extent of the moisture-proof luminaire and the longitudinal extension of the access opening 6 can be oriented parallel thereto, for example parallel to the main axis S.

As in the example shown, the access opening 6 is advantageously formed at a location in the housing 2, which is opposite to the cover 4, in this case in an upwardly facing top wall of the housing 2.

Preferably, the passage opening 8 is provided only for the passage of the power cable 10 and designed accordingly small. Therefore, the size of the access opening 6 is preferably larger than the size of the passage opening 8, for example, greater than three times the size of the passage opening eighth

In order to make the moisture-proof lamp overall moisture-proof, it also has the above-mentioned cover, which is designed such that it closes the access opening 6 correspondingly tight, so in particular moisture-tight. Of course, the lid is preferably reversibly removable to allow repeated accessibility through the access opening 6 to the connector 12.
