Description

The present invention relates to a window lamp, which can be used as a safety light, escape sign or escape route lighting, with a basic housing, from the base of the window lamp can be modularly assembled. Furthermore, it relates to a use of the window lamp and a method for adapting a safety light.

State of the art

Disc lights come in many shapes. A disc lamp comprises a plate-like display surface, which can be arranged with a pictogram printed across a presumed or fictitious detection direction. The plate-like surface is designed as a disk or as a disk body. To promote a recognition range, the disc can often be illuminated or illuminated. This means that the viewing distance is directly extended by the use of light. Creatively sophisticated disc lights carry light inside the disc-like body, which emerges over the wide surfaces. The light can be initiated via a smaller, lateral surface, which can also be referred to as a narrow surface.

A part of the window lamp is doing the basic housing, for the inclusion of a lighting electronics, one or more suitable lamps, for mounting the window lamp to a component such. As a ceiling and for the attachment of supply cables, so to speak as a terminal box, can be used. Such a basic housing therefore has a minimum dimension to accommodate all components intended for the basic housing, but for aesthetic reasons the basic housing should be as inconspicuous as possible.

An extremely box-like design of a basic housing can be found in the catalog "CEAG-Handelskatalog 2010, - Emergency lighting, - Radio alarm system CS32" of CEAG Notlichtsysteme GmbH, Soest, Germany (see in particular page 12). A sharp-edged or acute-angled box carries a disk adjoining the underside, which has a narrow side extension, which continues almost the entire narrow side of the octagonal box. The disc lamps designated as single-battery emergency lights by Inotec Sicherheitstechnik GmbH, Ense, Germany, which are shown in the catalog "single battery lights", use the same concept as the lights of CEAG Notlichtsysteme GmbH, namely a sharp-edged box over its entire narrower width with a disk body that is about the same width as the box to continue. To attach the window lamp carries another, slightly discontinued existing mounting box the support box of the disc body. There are therefore two boxes and a disc-like body the disc lamp.

A luminaire series of modular luminaires is advertised under the name "DIN Concept" by Dietmar Nocker Sicherheitstechnik GmbH, Linz, Austria, equipped with LEDs from a set of components according to self-promotion up to 100 different combinations of different security lights, u. a. also in the design of a window lamp allowed.

With the titles "emergency lighting design RI", "emergency lighting design RM" and "emergency lighting design RX" shows the Schrack Technik GmbH, Vienna, Austria a series of window lights, extending from the block-like box as a carrier body for the disk body of the previously designated disc lamp designs by draft angles in the vicinity distinguish the disc body in an aesthetically pleasing manner. The disk body can be mounted in different relative positions to the body, so that greater flexibility in the choice of the installation site is offered.

Disc lights are available in different power supply versions, as centrally supplied lights and as lights with single battery supply, if the central power supply should be interrupted or even collapsed.

How control technology using the general energy supply lines for the emergency light a supply can be ensured in case of interrupted general supply, if the individual lights are not individually supplied, so are not equipped with individual batteries, can be exemplified the DE 10 2007 062 999 B3 (Patent owner: RP-Technik e.K .; filing date: 21.12.2007), the DE 10 2007 062 957 A1 (Applicant: RP-Technik e.K .; filing date: 21.12.2007) and the AT 506 780 A1 (Applicant: RP-Technik e.K., filing date: 19.12.2008), which in turn list other references. The window lamp can be operated in a configuration as a single battery lamp; in the more advantageous installation variants, one of the previously mentioned control and power supply methods is used.

Another important aspect of escape sign luminaires is the recognition distance. There are many different factors in the recognition range. Among other things, the detection distance of escape sign lights is influenced by the type of illumination and the uniform distribution of the illumination of the escape sign. Exemplary may on the DE 10 2008 051 187 A1 (Applicant: RP-Technik e.K., filing date: 14.10.2008), which illustrates how the clever use of specially selected LEDs can reduce the energy requirements of a luminaire while still improving the homogeneity of the illumination of the display surface can, whereby the recognition distance can be increased. An increased recognition distance means that fewer emergency lighting luminaires have to be installed along an escape route, which in turn contributes to the reduction of total energy consumption. By additional optical and acoustic measures, the recognition distance, such as in the DE 10 2008 017 656 A1 (Applicant: RP-Technik e.K .; filing date: 05.04.2008).

It is widely observed in lighting technology a tendency to use LEDs with increasing intensity. Particularly advantageous are LEDs that operate with different or more maxima. The LEDs emit light cone. How such LEDs are realized and what properties they have can be exemplified by DE 10 2005 019 278 A1 (Applicant: LG Philips LCD Co., Priority date: 29.04.2004). Additional information can be the WO 2007/036 185 A1 (Applicant: OSRAM OPTO SEMICONDUCTORS GMBH, priority date: 30.09.2005).

The aforementioned invention descriptions define and explain helpful concepts and facts for further consideration.

However, safety lights, emergency lights and emergency exit lights are primarily concerned with increasing the visual range optically and for visual perception.

In the DE 41 29 266 A1 (Applicant: Dr.-Ing. Achim Willing, filing date: 03.09.1991) various possibilities are discussed, such as with prism arrangements on the entrance surface in a light distribution body, the z. B. serves as an indicator light, the light propagation in the light distribution body can be improved.

The DE 197 01 132 A1 (Applicant: Dr.-Ing. Willing GmbH, filing date: 15.01.1997) shows a disc lamp with light guide or a Lichtleitscheibenanordnung, wherein a portion of the light is used to backlight a termination surface.

A box-like lighting fixture with light-emitting surfaces, through which light can emit a fluoroscopic also a pictogram, is in the DE 20 2008 008 977 U1 (Owner: Pasedag, R .; Filing Date: 04.07.2008). The lighting fixture can also be used as a rescue sign luminaire.

In a flat diffuser light of light-emitting diodes in connection with a space-saving structurally integrated design according to the utility model DE 297 02 779 U1 (Owner: INPROTEC Innovative Production Technology Willy Reisen, filing date 17.02.1997). A strip-shaped circuit board forms a carrier element for the light-emitting diodes. A housing can serve as a cover or for fastening the carrier element. Electrical equipment may be provided, on whose connection and accommodation no indications emerge from the description.

Some aspects of an indicator light gemall DE 297 02 779 U1 can also do that US Pat. No. 6,539,657 B1 (Proprietor: Genlyte Thomas Group LLC, Filing Date: May 9, 2001), wherein in the described embodiments in particular a lens system for improving the light irradiation is used in a disc lamp.

In the published patent application DE 197 46 854 A1 (Applicant: Dr.-Ing. Willing GmbH, filing date: 23.10.1997) describes a escape sign luminaire with light-emitting diodes, which should work in emergency operation in case of power failure with adjusted luminance. There are two power sources are used, being operated in a mode with a power source from a network operation, a fluorescent lamp whose light can be split with prisms in two cones, z. B. for an orientation lighting. Furthermore, a reflector for focusing the light of the fluorescent lamp for a sufficient light output is present. In an emergency mode with reduced brightness and use of the second power source, light from light emitting diodes is radiated into a light disk arrangement, with which a safety indicator such as a removable pictogram can be backlit or illuminated. How the power supply is realized is not described.

A schematic configuration of a combination light with LEDs shows the DE 197 47 079 A1 (Applicant: Dr.-Ing. Willing GmbH, filing date: 24.10.1997). The example of a escape sign light is explained how light from multiple LEDs, z. B. using the light cone constricting optics for sufficient illuminance, is irradiated through three light entry edges in a light disk assembly with a pictogram. In this case, the total reflection should be interrupted in particular by measures for light deflection. In front of a fourth edge of the lens are a plurality of LEDs, which are directed to an escape route over a distance and their respective assigned light cone is to overlap or overlap with other light cones for illuminating the path, although a light bundling optics can be used. An arrangement of light emitting diodes with aligned light cones on strip-shaped strips in the upper region, on both sides of the lens is possible. Details regarding assembly of the assembly and a required electronics remain unclear, so it can be assumed that the combination light can only be used in one operating mode.

task

In the installation of windscreen lights as emergency lights or as emergency lights or escape route lights repeatedly installers express the desire to want to meet their assembly order with the simplest possible side logistics. Occasionally, the true light and visibility conditions at the installation and installation site can only be speculated in advance. Adjustments to such circumstances often prove difficult.

When installing such luminaires, it is particularly important to observe the observance of a detection distance. The recognition range of lighting systems and devices is specified by standards. How the recognition distance is determined, can also be found in relevant regulations. Regulations of relevant professional associations supplement the standard requirements. In Germany, many emergency lighting installation installations must comply with the standards DIN 4844/1 and DIN EN 1838. In many Western European countries, additional standards such as DIN EN 60598-2-22 and DIN EN 50172 must be observed. For reasons of simplification, the recognition range is often determined by a rule of thumb, which with h = l / Z Is accepted. A height h of the display character, for example a pictogram, is given by this formula when a desired recognition distance l is divided by a distance factor Z. The distance factor Z results from empirical values. The empirical values include, among other things, the luminance distribution, the hue of the escape sign, for example green, and the usual visibility. The visibility and lighting conditions present on site, especially in large public buildings, sometimes deviate from the expected conditions. The escape sign luminaire installation is often one of the last installation work involved in creating a building. The installers have to cope with the given conditions. Lamps intended for installation are often not used; occasionally new luminaires must be procured for changed installation locations.

The gem. of the DE 20 2008 008 555 U1 (Applicant: Roland Pasedag, filing date: 30.06.2008) and the DE 20 2008 008 977 U1 (Applicant: Roland Pasedag, date of filing: 04.07.2008) solutions for the simplification of logistics in connection with safety luminaires in the trade union design can not be directly transferred to the window lamp.

There is thus a need for a window lamp that meets the requirements mentioned.

invention description

The object of the invention is achieved by a window lamp according to claim 1. Advantageous developments can be found in the dependent claims.

The present invention relates to a window lamp, which is in particular convertible or changeable, that is thus adaptable to the given conditions. The window lamp has a flat, disc-like area, which is preferably illuminated. To a disc light so belongs as an element a disc-like body, the disc body. It is particularly advantageous if the pane body is not only illuminated, but even backlit. The term "backlit" means that the representation on the disk body, z. As a pictogram, is illuminated from its rear side. The disk body offers a larger area, for example 120 cm ² or 150 cm ² . The surface is used for the distribution of light. In addition, the surface can be one-sided or two-sided for attaching a representation, which is preferably a pictogram, z. B. by printing or hanging up, use.

One component of a window lamp is the basic housing. The base housing has a dimension such that electrical and / or electronic components can be accommodated in the base housing, such as a ballast. Furthermore, the base housing serves to hold at least one light source. Particularly advantageous is the use of an LED to generate the light distribution, which is to enter the disk body.

The window lamp has several bulbs such as LEDs. The lamps or the LEDs are located in or on the base housing. The bulbs or the LEDs are aligned so that they shine away from the base housing in the direction in which the disk body can be arranged. Here, the LEDs can be assigned to different groups. There may be LEDs that are responsible for the permanent lighting, there may be LEDs that can be varied in intensity or in their illuminance. Several LEDs have a deterministic light distribution. This means that these LEDs emit light with individual light cones. With such LEDs, there are at least two maxima.

So that the disk body is illuminated as evenly as possible, the light distribution that emerges from the LED can be asymmetrical or non-uniform. It is advantageous if the LEDs used LEDs with several, z. B. at least two, light cones are. The light cones represent maxima of the illuminance locally. If the space is described by spherical coordinates around an LED, then two maxima can be found in the spherical coordinates. The LED can be designed so that two or more maxima of the illuminance are present in front of the LED in the room. The light from the LED emerges focused, amplified in individual areas.

The luminaire electronics are designed in an advantageous embodiment for a centrally supplied emergency lighting system, a so-called central or group battery system. Based on the information in the supply voltage, the window lamp switches from one state to the next state. If an altered energy supply is applied to the supply spiders, then in one embodiment, an electronic unit detects that a change of state has taken place. The basic housing is advantageously so large that also accumulators can be inserted if instead of a central battery system, a single battery lighthouse concept to be implemented. In one embodiment, the luminaire electronics can comprise such circuits that the luminaire electronics are suitable both for single-battery operation and for central battery operation.

The luminaire electronics should be able to control the light intensity if a disc lamp equipped with as many functions as desired is desired. The luminous means controlled by the luminaire electronics or the at least one controlled luminous means should be variable in its brightness. The light source can be operated brighter or darker depending on a change in resistance of a light-dependent resistor. Another indication can be taken from the supply voltage or the supply energy. The voltage in centralized emergency lighting systems is often changed depending on the emergency operating state, z. B. a DC voltage is forwarded via the supply lines in case of power failure. The luminaire electronics may include a voltage detector responsive to DC voltage.

The disk body to be fastened in each case determines by its flat extent a plane which can be continued at the edges of the disk body, that is theoretically reaches into the infinite. Although the disk body is a flat body, but it may be referred to simply as a plane. The plane is thus on or in the disk body. Outside of the plane to be opened by the disk body, the flat body is considered to be a plane, there is a lighting means, in particular an LED. The lighting means is arranged outside a plane spanned by the disk body in the base housing. The light, which is distributed in a conical shape, radiates indirectly into the disk of the disk body. Part of the light illuminates the disk body. The disk body is illuminated. The disk body is illuminated innwandig. Irradiating the surface of the disk body with light enhances the recognizability of the symbol, e.g. B. the pictogram.

In an advantageous embodiment, the light maxima of one illuminant radiate in a different direction than the maxima of another illuminant. The maxima can lie on one axis. The bulbs open in a plane. The light exit surfaces of the bulbs end in the same plane. In the case of LEDs, one LED may be rotated by 90 ° with respect to the other LED. The rotation, in particular the 90 ° rotation, takes place in the same plane, ie in an angle in the plane. If a second level is drawn in the room, z. For example, the floor of the escape route can be considered as a projection plane, the second plane being oriented away from the pane body, in particular running transversely to the pane body, a plurality of illumination maxima can be found in this plane.

The disc lamp has a Lichtabstrahlcharakteristik in one embodiment. Instead of the term light emission characteristic, the term light distribution curve is frequently used as a technical term. The light distribution curve of the window lamp is distributed in the room due to the bulbs, the arrangement of the bulbs and the type of bulbs with maxima and minima. Shown in spherical coordinates, the light emission characteristic of a lamp is kidney-shaped. The overall light emission characteristic results from the superimposition of the distributions of the light emission characteristics of the individual light sources. Does the supply voltage, z. B. from an AC voltage to a DC voltage, the Lichtabstrahlcharakteristik can be changed, for. B. in accordance with the supply voltage from a first to a second characteristic be switched. The switching can be realized in many ways. Additional lighting means can be switched on or off. Stronger or weaker electrical currents may be conducted through the illumination means. Higher or lower voltages can be applied to the illumination means.

The lighting means are arranged according to an aspect of the invention in the base housing at different locations. The points are chosen so that at least some of the bulbs are not in the extension of the disc body. The extensions are thought of or continued on the sides of the disk body, which are delimited by the narrow longitudinal surfaces. The light emission direction of the light source passes by the disk body. More light is passed through the disk body. The disk body is in this case light and backlit. The disk body is thus illuminated and light can escape from the disk body. Due to the clever lighting a shadow under the window lamp is largely avoided. The illuminated area below the disk body or in vertical extension of the disk body can be regarded as shadow-free. If the maxima of the illuminant radiation are deflected past the disk body, the light cones reduce the shadow effect. One advantage is that such a luminaire is not only to be used as a window lamp or escrow light, but can additionally be used as an escape route luminaire and as a safety luminaire.

The recognition distance of a window lamp is determined inter alia by the sufficiently illuminated surface of the disc body used. Depending on the observed standards, it is not allowed to create spots that are too bright on the one side or too small spots on the other side in the window body. The recognition distance is a malt, which is usually given in meters. If it is possible to ensure a clear view of the window lamp, a detection distance within maximum distances, in the sense of maximum permissible distances, of the window lamp, ideally in a right angle to the window lamp, held. The observers are slightly laterally to the surface normal, therefore look at a small angle to the surface normal to the surface. The detection distances between individual window luminaires must be designed so that an escape route for passers-by along the signposted escape route can be recognized from the window lamp to the window lamp. If the recognition distance of a single disc light increased, so are z. B. to install in a correspondingly long corridor less disc lights. The escape route can be reproduced between the two panel lights using the two surface normals of each panel lamp. If the window lamp illuminates its immediate surroundings almost without any shadow, the window lamp can be used simultaneously or as a safety light. A luminaire can perform both the function of a rescue sign lamp as well as the function of a safety light. It is not necessary to install two lights alternately. It is sufficient in this case, if a corresponding disc light is installed at this point. The disc lamp according to the invention reduces the logistical effort.

Advantageous developments can be found in the following explanations, which may also reveal their own inventive aspects.

According to a further aspect, a set of a corresponding pane light includes a plurality of components that modularly yield the pane light in their different configurations. By assembling a selection of the components and assembling, the window lamp can be changed. It can be replaced individual components, in particular the disk body of the window lamp, so that a first disc lamp is replaced by a second disc lamp. However, essential components of the window lamp remain unchanged. One such component is the basic housing. The basic housing is advantageously designed so that it can be mounted in various ways. In one embodiment, the basic housing is mounted on a ceiling. The basic housing can also be mounted on a wall of a building. By using a flush-mounted frame, the basic housing can also be recessed in a ceiling or in a wall. The lens lights are predominantly intended to be mounted in the overhead area of regular public traffic, so that by looking up the disc lights can also be seen by people in a larger group. The window lamp is suitable for overhead mounting.

To improve the view, the larger disc surfaces are aligned in sight or gaze directions. In addition to the large visible surfaces, the disc body of the disc light, the actual discs, longitudinal narrow surfaces. At the end of assembly of the disk body is usually perpendicular, so aligned in its direction of gravity on the ground, arranged. The disk body stands vertically out of the basic housing.

If the basic housing is designed box-shaped, it can be in different Install attachments. Thus, both a longitudinal side of the base housing can be used for ceiling mounting, as well as a narrower transverse side for attachment to a wall. In both cases, the basic housing can be arranged transversely to the escape route; while the ceiling mounting a longitudinal side attaches to the ceiling, when mounted on the wall, the window lamp is screwed in a protruding from the wall orientation. For this purpose, the disc lamp in its basic housing perforation or breakthrough points, can be pushed through the connecting means such as screws or screwed through. The box-shaped part of the pane lamp, the basic housing, is preferably provided with slightly rounded edges, so that numerous, different fixing positions of the basic housing can be selected. Unnecessary openings can be closed by the set associated covers.

The basic housing is a closed housing, from which the light of the lamp can emerge in one direction. For the basic housing has a light transmission body. The light transmission body and the mounting bracket may be identical, in an alternative embodiment, the window lamp immediately after the light emitting diode LED on the light transmission body, which at the same time for receiving the mounting bracket, z. B. by a rail can be used. If no mounting bracket to be attached to the light transmission body, so can an additional cover such as an additional diffuser, hang on the light transmission body. The light emerging from the light source passes through the light transmission body and then passes through the mounting bracket then penetrates into the disk body.

Part of the window lamp is a mounting bracket. The mounting bracket is the connecting link between the disk body and the base housing. For this purpose, the mounting bracket is attached to the base housing. The mounting bracket picks up the disk body. The mounting bracket can be in one piece or in several parts. Several smaller mounting brackets can be a larger, multi-piece mounting bracket.

The relative position between the basic housing and selected reference positions of the disk body can be adjusted. The attachment between the disk body, mounting bracket and base housing is changeable. The relative position can be changed, for example, depending on the selected disk body, z. B. longitudinally displaceable position. About a longitudinally displaceable positioning, the longitudinal narrow surface of the disk body could be displaced locally. For reasons of simplification, a surface normal is formed on the two largest surfaces of the disk body. The pane lamp is designed in an advantageous embodiment so that it can hold different disc body. Different disk bodies are disk bodies that have different surfaces, so-called visible surfaces. Thus, the area of the first disk body is larger than the area of the second disk body. The surfaces can special surfaces, such. B. Illustrations to escape route indication, have.

The mounting bracket can be fixed to the base housing. However, the fixed mounting bracket is not permanently assembled, not insoluble in a once zusammenzufügenden state, but mounting bracket and base housing can be separated by a few simple steps. If the longitudinal narrow surface of the disk body provided for the inclusion in the mounting bracket, the light can penetrate from the base housing over the longitudinal narrow surface in the disk body.

The larger sides compared to the longitudinal narrow surface, the visible or large areas, can be covered by pictograms. The light which has entered laterally over the longitudinal narrow surfaces thus reaches the rear side of the pictograms after a deflection, preferably by 90 °. The light comes out through the pictograms.

The window light has a universal mounting bracket. The universal mounting bracket has several mounting options in interaction with the base housing and disk body. Disk bodies of different sizes, which can thus cover different detection widths, can be mounted in the same mounting bracket, if the attachment can be adapted to the corners of the visible surfaces of the disk body.

By means of this measure, the window lamp can remain mounted with its basic housing unchanged, if an adaptation of the window lamp to different detection distances, in particular in accordance with the relevant standards for lighting systems, in particular in public buildings, perform.

The mounting bracket is preferably designed in several parts. A first part of the mounting bracket is a holding device, which is adapted to a second part of the holding device, in particular an edge region of the disk body. The first part of the holding device and the second part of the holding device are formed opposite. This means bolt-shaped projections or elevations or depressions in a holding device find their exact counter-shaped equivalent in the other fixture. Thus, bores or groove-shaped recesses may be present in at least one holding device.

The joining of the first part with the second part is effected by a positive attachment of the holding device to its counterpart. By means of a positive connection, it is particularly easy to realize a multiple detachable connection of the parts of the mounting bracket. Thus, the disc light can be adjusted several times.

As fastening means are locking pins, stops, pins and angular attachment means. With the help of the attachment, the relative position of the disk body is adjusted to the basic housing. Larger disk bodies extend further in a lateral direction along the base housing than smaller disk bodies. Larger disk bodies span over a greater width along the base housing.

The disk body is fixed to the body so that the disk body extends the body in one direction. Basic housing and disk body are designed in an advantageous embodiment as a contiguous, laterally adjoining components using the mounting bracket. In the transition region between the mounting bracket and the base housing on one side and mounting bracket and disk body on the other side are angled transitions exist, there is a stepped implementation of the disk body on the base housing instead. In an advantageous embodiment, the disk body is narrower than the base housing.

In a particularly advantageous embodiment, the mounting bracket comprises a U-shaped cross section. A leg of the U-carrier extends to the first part of the holding device. Due to the U-shaped design of the mounting bracket of the disk body is enclosed on several sides. Also inclined disc body (compared to the basic housing) are feasible through the fixed, positive-locking enclosure of the disc body. By this measure, the recognition distance can be adjusted by the orientation of the surface normal to a fictitious, distant as possible viewer, in particular to his eye level.

According to a favorable embodiment, the window lamp is designed so that one and the same connection space is provided to the basic housing for the respective disk body. This means that only one disk body can ever be connected to the basic housing. The window lamp is configured for a certain maximum detection distance. If the disc lamp to be changed to a different recognition distance, the previously proposed disc body is to be substituted by a new disc body. If, due to unfavorable light conditions, the recognition distance is insufficient for the disk bodies provided for mounting, the same already installed basic housing can be left at its installation location due to exchangeability of the disk body, and the disk body deemed insufficient is preferably replaced by another disk body with a larger area, to replace. For this purpose, the window lamp has at least one attachment, via which the mounting bracket and the disk body can be matched to each other, in particular to the wider surface of the disk body can be adjusted.

In addition to disk bodies with pictograms, another set of disk components can be added to a set of components of a pane lamp, which distributes a laterally injected light from the basic housing over its largest surfaces into the adjoining space without any pictogram. The pane lamp, which can ideally be installed both as a ceiling mounting and as a wall mounting in on-wall and flush-mounted, supports the pane body in such a way that easy access to the mounting bracket is possible. The mounting bracket is accessible in the assembled state of the basic housing. The mounting bracket retains the disk body in a releasable manner. A snap fit facilitates the connection and disengagement of the disk body from the mounting bracket. Depending on the use of the window lamp, z. For example, whether the window lamp is to be used as a safety light, as a escape sign, escape route or combined escape route and escape route, the corresponding disc body is mounted in the mounting bracket. With just two steps, one disassembly step and one assembly step, the window lamp can be adapted to the changed conditions, in particular without having to remove the basic housing from its mounting location.

The window lamp can be changed both in type, ie in relation to the type of lamp (eg escape sign, escape route, disc-type), as well as in relation to the maximum permissible detection distance. If the majority of the light from the light source is introduced into the pane body, preferably distributed as uniformly as possible, then the pane light can be adjusted with respect to its permissible detection width without changing the light source. The recognition distance of the window lamp is customizable. Advantageously, the same set "disc light" for both an overhead mounting a escape sign lamp as well as for wall mounting a similar looking Safety light can be used. Although escape sign luminaires are required in buildings of public character, many architects and builders desire that the escape sign luminaires should discreetly take a back seat and not create a dominant character of the overall impression of a hallway. For this reason, the installer often receives the requirement to have to make do with the smallest possible areas of the disk body. If he is not a modular interchangeable disc light available, the smallest for each of the intended installation spotlight is to be mounted. The logistical effort increases considerably, because pane lights, which are identical in principle, but differ in their dimensions with each other, must be procured in the correct quantity for the assembly order.

The replacement of the disk body, to say, the replacement of a disk body by another disk body (regardless, with or without pictogram) can be carried out in a few minutes by a few assembly steps. After a removal-disassembly of the first disk body, the second disk body is placed in place of the first disk body in a subsequent plug-in assembly. Change the circumstances regarding the escape route, z. B. because a first escape route is due to conversion to happen only with disabilities, so you can place another disk body with another icon and an alternate escape route is signposted. Due to the easy plug-in mounting, the correct disk body can be installed in the mounting bracket.

The connection of the respective disk body is due to a form-locking. By a positive connection of the disk body no unnecessary forces are applied to the disk body, the disk body are made in an advantageous embodiment of a plastic. The plastic has increased embrittlement when excessive forces due to the mounting bracket are applied to this. As plastic is z. B. polymethylmethacrylate.

The positive connection between the disk body and a base frame of the mounting frame can be realized in various ways. It is advisable to provide an out / hang mounting device. Also, a Ausrast- / snap-mounting device may be incorporated. As a third option, a sliding assembly offers as a Ausschiebe- / insertion assembly. All listed types of installation can be combined with each other; they are each designed so that a re-releasable connection is generated.

The homogenization of the illumination of the disk body can be promoted by a diffuser. The diffuser can be kept as an independent component, alternatively, the diffuser property can also be incorporated in the mounting bracket or another, arranged between the disk body and lamp component. The diffuser should distribute the light in the area of the longitudinal narrow surface of the disk body, scatter or fanned. By this measure, local maxima, which may still be present due to the light distribution from the LED, largely aligned. The pictogram on the disk body is illuminated more uniformly by such measures.

The first two parts, the first part of the holding device and the second part of the holding device can be supplemented in one embodiment by a third part of the holding device. The third part of the holding device is advantageously a hook arrangement, which allows a spaced, detachable connection of the mounting bracket with the disk body. The disk body is hooked into the hook assembly. The positive connection is further stabilized by such a measure.

As a particularly advantageous material for disc lights according to the invention has in relation to the mounting bracket, a transparent plastic such. As polymethyl methacrylate, excellent. Also, the disk body may be made of such a plastic. In order not to unnecessarily lose light from the base housing in undesired directions, the base housing should have a different opacity from this. Above all, the mounting bracket and the disk body should have good light transmission properties, so that as little electrical energy is converted to produce a sufficient illumination.

If the measures described above are consistently implemented, in particular also in accordance with the additional measures previously discussed as state of the art by the Applicants and marked as in-house, it is possible with a disk body having an area of about 120 cm ² to 150 cm ² has to ensure a recognition range in a range between 8 m and 40 m. The light source is designed so that also wheel body with an area of 800 cm ^{2 can be} sufficiently illuminated or illuminated. Although the disk body is comparatively small, the recognition distance for a - in comparison to other window lamps - very wide spacing.

The field of application of a pane lamp according to the invention can thereby be extended be that at least the base housing is designed waterproof. Furthermore, the field of use of the window lamp can be increased by the fact that the base housing comprises a flush mounting frame. Includes the sentence that represents the components of a window lamp, in addition to suitable disc bodies also additionally a flush mounting frame, which can be advantageously incorporated directly into the basic housing, the same disc light can be installed as both surface-mounted and flush-mounted. If the basic housing also has a waterproof encapsulated interior, then such disc lights can also be used in wet areas, such as in swimming pools. The logistics in connection with the composition of the windshield lamp to be mounted additionally simplified for the fitter.

Since several points in the base housing for mounting the base housing to another component are prepared, and in addition the basic housing no exclusive preferred direction, but several different preferred directions can be assigned, for. B. because the marginal shaping of the basic housing allows very evenly rounded, the disc lamp can be installed in many different locations. For prepared openings in the base housing, additional covers, caps and inserts may be included with the set of the window lamp.

Because several preferential directions are provided, the window lamp can also be mounted upside down. This means, for. B. above a door, directly above the door frame, a disc lamp described above can be mounted when the base housing is attached as a pedestal to the wall and held out of this by the mounting bracket, the disk body protrudes against gravity.

Another advantage arises when the window for the passage of the light of the bulb is wider than the longitudinal narrow surface of the disk body. That is, the light transmission body is wider than the mounting bracket. In this case, the window lamp serves both as a escape sign and escape route. The window light illuminates the escape route. The windscreen light simultaneously signals the escape route. Part of the light is transmitted in the disk body. Part of the light exits directly from the base housing and radiates from the window lamp without passing through the disk body.

The brightness of the lamp or the light source is changeable, z. B. dimmable. The brightness of the light source is adjusted based on a parameter. The parameter correlates with an ambient brightness. The parameter is a usual brightness, in particular ambient brightness assigned. Such a parameter can be a voltage, so z. As a DC voltage or an AC voltage to be. The voltage type of the supply voltage can be traced back to the ambient brightness. Depending on the voltage, more or fewer lights are in operation. Therefore, there is also a higher or lower brightness. In a bright environment, the escape sign should have a higher brightness than 500 cd / m ² . If the environment is very dark, the brightness should be in the range of only 5 cd / m ² . If a DC voltage is present as the supply voltage on the supply lines in the case of a central battery system, then a dimmed or a darker environment can be assumed to be very likely.

A disc lamp according to the invention is characterized by many advantages. It can be used particularly well as a window lamp with escape route indication or indication of an escape route as well as for illuminating a path that is intended as an escape route.

As mentioned above, there are many occasions and reasons why a once selected disc lamp is subsequently adapted to different visibility conditions, detection distances, escape route directions and illuminance levels. If the intended use of a room is rededicated, the window lamps mounted in the room can be adapted to the new conditions, in particular by means of a disassembling step and an assembly step, by means of a few assembly steps. If in this case a disc light is no longer available as a escape sign light, but only take over the function of a regular light, the disc body can be removed from the mounting bracket, if necessary, the mounting bracket can be removed and unwanted wells are compensated by a replacement mounting bracket. By such measures, a quick conversion of a window lamp, which was previously a safety light, succeeds to a escape sign and vice versa.

The window lamp is suitable for use as a luminaire in a safety lighting system.

The different measures presented contribute to the fact that a pane lamp according to the invention, although it is adaptable to its conditions of use, hardly causes a glare of the viewer. The glare, partially Disc lights is known, so that the highest possible recognition distances are achieved, is largely reduced.

The pane lamp according to the invention contributes to the fact that the logistical effort during the initial assembly for the installer is reduced and that additionally mounted disc lights can also be subsequently adapted to changing conditions. It can also be said - a disc light for almost all occasions.

1 shows a basic housing 3 That instead of the ground housing 3 '' to 16 Part of the disc light shown there 1 can be. The basic housing 3 to 1 is elongated. The basic housing 3 is cigar box-like. The basic housing 3 looks like an elongated, slim box. At the smaller of the different sized front sides of the basic housing 3 are positive fasteners such as brackets 69 for the positive connection with a mounting bracket 65 intended. The mounting bracket 65 go on one side to the edge of the basic housing 3 , In this page, which points to the outside, is a screw hole 67 admitted. Through the screw hole 67 can be screwed through a mounting screw for attaching the basic housing to a wall or a ceiling. Several sides of the mounting bracket 65 are designed similar to each other. This deviates from the side of the mounting bracket 65 that the screw hole 67 has, off. The mounting bracket 65 is via the plug-in flange 71 using the parentheses 69 on the basic housing 3 attached. Through the plug-in flange 71 can the mounting bracket 65 be plugged in different positions. In the rectangular plug-in flange 71 to 1 arise four different positions, such as the mounting bracket 65 on the plug-in flange 71 can be plugged. Thus, four different sides of the basic housing 3 be chosen so that the basic housing 3 with one side against the support wall or the carrier ceiling of a building. Furthermore, in the picture below 1 a terminal block 21 in the cable opening 23 to see. The installation cables of the building or individual wires of an installation cable of the electrical installation of a building can be placed in the terminal block 21 be plugged into it. The basic housing 3 thus offers many different positions, such as the basic housing 3 on the supporting component "wall" or "ceiling" or "niche" or "floor" can be attached. The basic housing 3 has several preferential directions. The edge areas are slightly rounded off at the base housing 3 , Incidentally, the border areas, they are compared with each other, evenly configured. Will be the top surface of the basic housing 3 chosen as a contact surface, so the cable (not in 1 shown) completely hidden in the basic housing up to the terminal block 21 be guided.

The distribution of light density is determined by the orientation of the bulbs 15a . 15b . 15c . 15d . 15e certainly. The lighting electronics 13 can the bulbs 15a . 15b . 15c . 15d . 15e on the light bulb board 17 different drive and thus the light emission characteristic of the disc moisture 1 to 16 adapt to the ambient conditions or vary the Lichtabstrahlcharakteristik.

In 6 is the mounting bracket 25 , which roughly looks U-shaped, slightly larger than in 3 shown. The mounting bracket 25 has two thighs 27 that run parallel to each other. The thigh 27 finish the U-shaped Mounting bracket 25 , The mounting bracket 25 represents the first part 29 the holding device. The retaining pin 37 with its conical shape of the catch nose 81 represents the third part 33 the holding device. The mounting bracket 25 has several selection holes in which the retaining pin 37 can be enforced; being the retaining pin 37 through the latch 81 in the mounting bracket 25 self-assured. As in 16 good to see, points the disk body 39 the second part 31 the holding device. The mounting bracket 25 has several times the first part 29 the holding device. The disk body has at the corresponding points the second part 31 the holding device. With such objects as the retaining pin 37 to 6 become the three parts of the holding device 29 . 31 . 33 positively connected with each other.

The mounting bracket 65 that out 1 in the installed state is already known, is in greater representation in 7 pictured again. With the help of the mounting bracket 65 can different preferred directions for the basic housing, eg. B. the basic housing 3 to 1 , to be selected.

To increase the tightness against water ingress are the set of components that can be assembled into a disc lamp, z. B. several covers 77 , as in 8th and 9 presented from different perspectives, settled by their flanges 71 can be attached to the basic housing: Further breakthroughs and openings, such. B. the cable opening 23 to 1 in the basic housing 3 , can through a lid 79 be closed against splash water entry or other water ingress. For the fixed attachment of the lid 79 on the cable opening 23 are in the lid 79 locking lugs 81 ' . 81 '' incorporated.

For the installation of the window lamp 1 to 16 flush-mounted is a flush mounting frame 9 provided, a recording room 85 through his pursuit 83 . 83 ' surrounds. About the catch 81 ''' , above the cover frame 87 pivotable, so in pivoting manner, is arranged, the flush mounting frame 9 in the recess, z. B. in a ceiling, braced or locked. Additional brackets 69 . 69 ' are for the positive continuation of the flush mounting frame 9 intended. Thus, the flush mounting frame 9 Part of the basic housing 3 to 1 if about the brackets 69 . 69 ' the two components flush mounting bracket 9 and basic housing 3 be put together.

12 shows another basic housing 3 '' in a schematic representation of its outlines. From the basic housing 3 '' is the disk body 39 in axial extension. The bulbs 15a . 15b . 15c . 15d are each alternately on different sides of the disk body 39 arranged. The bulbs 15a . 15b . 15c . 15d stand laterally to the disk body 39 , The orientation or the light emission direction or the light characteristic of the window lamp 1' to 12 predominantly radiates on the disk body 39 past. A longitudinal narrow surface 45 of the disk body 39 extends between the bulbs 15a . 15b . 15c . 15d , The individual bulbs 15a . 15b . 15c . 15d are oriented differently. The orientation or orientation of the bulbs 15a . 15b . 15c . 15d done by turning the light bulbs 17 ' . 17 '' , The light bulbs 17 ' . 17 '' can be exchanged for each other. The light bulbs can be rotated by 90 ° in the basic housing 3 '' deploy. The optics of the bulbs 15a . 15b . 15c . 15d focus or they produce a conical light distribution.

Another arrangement of the bulbs 15a . 15b . 15c . 15d . 15e is in 13 shown. The disk body 41 is partly over the bulbs 15b . 15d . 15e and partly next to the bulbs 15a . 15c , The schematic representation of 13 is shown as the disk body 41 from its longitudinal narrow side 45 seen by the viewer. The weaker in their light intensity bulbs 15d . 15e are marked with a smaller cone of light than the more luminous bulbs 15a . 15b . 15c , The basic housing 3 '' takes the bulbs 15a . 15b . 15c . 15d . 15e on. The (not shown) luminaire electronics fits the light or the light intensity of the bulbs 15a . 15b . 15c . 15d . 15e at. The bulbs 15a . 15b . 15c . 15d . 15e are divided into different groups. The bulbs 15a . 15b . 15c . 15d . 15e can also be split into types. One group includes the bulbs 15a . 15b . 15c , The light output can thus be adapted to the ambient brightness or the ambient conditions.

From 13 known disc light is in 14 shown in different views in a schematic way. As in 13 is also in 14 to see that the bulbs 15a . 15b . 15c to be operated regularly while the bulbs 15d . 15e operated with reduced brightness. The light of the bulbs 15a . 15b . 15c . 15d . 15e radiates from the basic housing 3 '' as from, as the disk body extends with its visible surfaces. The lighting electronics 13 ' controls the bulbs 15a . 15b . 15c . 15d . 15e so on, that light on the surface 57 of the disk body 41 is directed past. The radiation direction 89 the maxima is outside the disk body 41 , The light of the bulbs 15a . 15b . 15c . 15d . 15e is partially deflected and partially directly to the disk body 41 passed to a shadow-free lower area under the disk body 41 to obtain. Shown is an embodiment in which by means of mirrors or reflectors 91 the light of the bulbs 15a . 15b . 15c . 15d . 15e is diverted.

A corresponding electronic circuit for the operation of the bulbs 15a . 15b . 15c . 15d . 15e to 13 is in 15 shown. The lamps LED1, LED2, LED3, LED4, LED5 are lined up in series by the resistor R1 in the current. The MOSFET Q1 is activated via the operational amplifier IC1, and the current flowing through the lighting means LED1, LED2, LED3, LED4, LED5 is balanced with the voltage divider D1 and R2. The negative input of the operational amplifier is located at the junction between diode D1 and resistor R2. With a correspondingly large deviation, the MOSFET Q1 opens and the current through the lamps LED1, LED2 is limited. At the terminals SV1-1, SV1-2 can further electronic circuits of the lighting electronics 13 . 13 ' be connected. The monitoring can be based on the voltage drop across R1, which must be within a certain voltage window.

16 shows the window lamp 1 in the version with a disk body 39 , the larger wheel body 39 is. At the basic housing 3 '' is the mounting bracket 25 Tailed, in the light through the diffuser 61 is initiated. The pictogram 47 makes the disk body 39 and with it the window lamp 1 to a rescue light 7 , This is the pictogram 47 an escape sign. The surface normal 55 from the area 53 stands in the direction of the viewer from the surface 53 from.

17 represents a similar configuration of a window lamp 1 as a escape route light 7 ' is composed as before 16 known. The disk body 41 has a smaller area 57 compared to the area 53 , The surface normal 59 points again in the direction in which a fictitious fugitive or viewer is accepted. The surface normal 59 helps to determine the recognition distance 51 within which limits the pictogram 47 on the disk body 41 can still be seen. The light from the basic housing 3 ' is via a diffuser 61 in the mounting bracket 25 relented. For the disk body 41 There are different mounting positions along the mounting bracket 25 , The diffuser 61 equalizes the light from the basic housing 3 ' , The light is along the longitudinal narrow surface 41 in the upper area 43 of the disk body 41 initiated.

Will the two representations of 16 and the 17 compared with one another, it can be seen that the surface sizes A1, A2 of the disk body 39 . 41 differ from each other. The area sizes A1, A2 influence the respective recognition distance 49 . 51 for which the disc light 1 is designed. Further influencing factors result from the type of illumination, the contrast intensity of the pictogram 47 , the color of the pictogram 47 and the lighting conditions prevailing at the type of installation. So can the smaller disk body 41 have an area A2 of 120 cm ² , while the larger disk body 39 has an area size A1 of 800 cm ² .

Will the escape sign light 7 ' to 17 no longer needed as such, as can in 18 represented by a few handles from the base housing 3 '' a safety light 5 be whose light passes through the diffuser 61 and the light transmission body 19 is evened out. To create a splash water safety, the ends are covered by the caps 77 locked.

The safety light 5 to 19 resembles the safety light 5 to 18 , The light transmission body 19 sits on the base housing 3 '' ,

In 20 becomes a ceiling mounting with the help of the flush mounting frame 9 shown. The hand of the mechanic only needs the locking lugs 81 ''' bring into the locked position and the flush-mounted frame 9 is prepared for the inclusion of the actual basic housing, provided the cable 75 from the cover frame 87 protrudes.

Is then the cable 75 on the terminals (not in 21 to see) of the basic housing 3 '' Hanging up, so can the safety light 5 on the basic housing 3 '' in the recording room 85 be pushed. The cover frame 87 covers the receiving space 85 in part. The locking lugs 81 ''' are dimensioned so that the flush mounting frame 9 the safety light 5 can hold reliably.

The cover frame after 21 is better to see in again 22 shown.

The 23 and 24 show how the diffuser 61 by two handles the character of the disc lamp (not shown in the 23 and 24 ) can transform.
