DESCRIPTION

Multifunctional light

The invention relates to a modular lighting system for linear lamps, which can be used in addition to applications in the field of general decorative lighting, in particular for safety lighting in the context of emergency lighting.

Escape route or safety sign lights can either be designed to illuminate a pictogram or to illuminate the back of a corresponding support surface if it is transparent. The latter design is very common in such applications because the structural and lighting conditions are easy to control and the lights can be manufactured inexpensively. A light housing to accommodate all functional elements consists of a lower housing section and a transparent, translucent or prismatically structured cover that holds the respective safety sign. Alternatively, the light housing is constructed from aluminum frame profiles, usually with a cuboid geometry, the outer surfaces are made of sheet metal parts and the front and/or back are made of opal discs that carry the information symbols.

Furthermore, light guide disc arrangements, also referred to as disc lights, are known in which the pictogram films are applied to translucent or clear transparent carrier discs and these are structurally and optically connected to corresponding light exit surfaces of the lamp housings in such a way that the luminous flux of the one or more lamps arranged in the interior of the lamp housing is coupled in.

Depending on the requirements in terms of visibility and placement in a building, escape route or safety sign lights are designed for different types of installation. A distinction is made between wall, wall bracket and ceiling installation, with pendant, rope or chain suspension being used for ceiling installation. The corresponding mounting elements are available as accessories.

According to current guidelines, there are defined geometries for pictograms, especially safety signs, which determine the shape and geometry of the carrier discs and thus the

The luminaires themselves largely determine this. The luminaire housings are always cuboid-shaped due to the necessary geometry of the light-emitting surface. Furthermore, the luminaire housings designed for use as pictogram luminaires, especially in the case of disc luminaires, can only be used for this purpose and cannot be used alternatively for decorative purposes. All known commercially available luminaires of this type have corresponding features.

A certain exception is described in DE 19817065; here a carrier disc is arranged at a distance in front of the light-emitting surface of the luminaire housing and is designed to be considerably larger than the light-emitting opening itself, which is adapted to the pictogram. This means that the carrier disc can serve as a certain decorative element if the edge is designed accordingly.

Ohmic light bulbs are increasingly being replaced as lighting sources due to their poor efficiency and harmful heating; commercially available fluorescent lamps, particularly rod-shaped ones, are mostly used, preferably with a tube diameter of 16 mm. The possibility of using light-emitting diodes, which are now very bright, is described in DE 19746854, whereby the use of the advantages of both lighting concepts, fluorescent lamps and light-emitting diodes, is proposed. Due to the lighting requirements described, a corresponding emergency light is operated with a fluorescent lamp when it is operated from the mains and with light-emitting diodes when it is operated in emergency mode.

Safety sign or escape route lights that use modern cold cathode fluorescent lamps with tube diameters in the range of 2 to 7 mm or modern fluorescent lamps with tube diameters of 7 mm (OSRAM, type FM6W to 13W) as light sources are not yet known for self-contained battery lights.

Additional path lighting using LEDs as lighting sources in conjunction with an escape route light is described in DE 19747079. Here it is proposed that, in an escape route light with a light guide plate into which the light from a large number of LEDs is fed via the side light entry edges, a sufficient number of LEDs should be arranged in such a way that their luminous flux is used to illuminate the path. As an alternative to the use of LEDs,

It is ensured that the escape route luminaire has a second lamp system which directs the light of at least one fluorescent lamp directly onto the path.

The luminaire housings of disc luminaires as pictogram or safety sign luminaires are made of sheet metal or plastic parts. The structural length of the luminaire housing is determined by the length of the carrier disc, which in turn is determined by the size of the pictogram, which thus determines the projected viewing distance for use of the luminaire in accordance with DIN 4844 or EN 1838. The functional elements of such a luminaire are: operating devices for the lamp(s) for mains and emergency operation, control electronics, lamps with corresponding sockets and holders, reflector systems, elements for the electrical connection and, in the case of self-contained luminaires, the corresponding battery (usually NiCd battery) with associated charging management with supply from the lighting network. These functional elements are arranged in the luminaire housing in such a way that, according to the respective structural conditions, they are screwed onto a carrier plate and wired directly to one another within the housing. The lamp is arranged in the lower area of the luminaire housing directly above the carrier disc, and its luminous flux is coupled into it. The lamp housing has a corresponding gap in which the carrier plate is attached. This design concept has the disadvantage that the respective lamp can only be used effectively with a carrier plate, i.e. as a pictogram lamp. Versions for other sizes due to larger pictograms or safety signs for greater recognition distances also require a geometrically adapted housing, which in turn has to be manufactured separately. Furthermore, decorative elements or design features cannot be arranged or are very difficult to arrange.

Smaller floodlights with cold cathode fluorescent lamps show a first approach to solving this problem. A uniform aluminum profile element is used as the lamp housing, which is only cut to the corresponding system size for different lengths of one or more rod-shaped lamps. Examples are the lights of the miniature display system ERG-O-FLOOD from ERG Elektro-Röhren-Gesellschaft Göttingen. They consist of a one-piece aluminum profile with a width of 35 mm and a height of 48 mm, which is closed off at the front with plastic end caps. A total of 12 different standard lengths are used.

FREEFLEX GmbH, Ettenhausen j ··; · ; ;. \'\ J : 18.02.01

offered. A transparent tube is arranged within the aluminum profile, which serves to accommodate a reflector profile. This reflector profile has one or more electronic operating devices on the back, whereby each operating device can control a lamp. The front of the reflector profile can be provided with an appropriately reflective coating, with the lamp arranged in front of it. This directs the lamp's luminous flux into a narrow light emission surface arranged along the length of the profile or optionally into a light guide disc arranged in it. The possible applications with and without a light guide disc arrangement are both in the areas of a pictogram light for advertising, information and safety signs and as a spotlight for decorative purposes. However, the design principle of this arrangement does not allow it to be used as a safety sign light with a single battery due to the high space requirement for additional functional elements, and there is no possibility of arranging additional lamps for additional path lighting.

The object of the invention is to introduce the advantages of using profile elements directly as luminaire housings in the constructive solution of various sizes of pictogram and escape route luminaires with light guide disc arrangements, to enable the system to be traced back to the function of a pure floodlight for general decorative lighting purposes even without the use of light guide discs, to realize additional path lighting via the possibility of arranging additional lamps in a decorative manner and, furthermore, to create a manufacturing advantage due to the modularity of the functional elements and components.

The inventive problem is solved by the arrangements described in the claims.

According to the invention, a uniformly designed base profile is used as a luminaire housing for a family of luminaires, with the functional elements required for the application divided into physically separate functional modules. With different functionality, functional modules of different types are created, the geometry of which differs for the same type only in the length in terms of the system size of the respective luminaire. The assigned functionality depends on the available installation space, the type and technology of the components.

as well as the technically possible and sensible interfaces with regard to their necessary electrical connections to each other. The system size is determined by the length of the light source. The functional modules are installed in a base profile as described and optionally in additional side profiles arranged on the base profile.

5 or additional profiles. The end caps on the profile faces, which in turn are designed in accordance with the protection requirements, secure the electrical and mechanical connections of the functional modules both to each other and to the outside world via their functional spaces. A particularly slim design of a basic profile to achieve a good design is provided by the tiered arrangement of several functional modules in the basic profile and by the use of rod-shaped lamps with a particularly small diameter.

The invention is commercially applicable, since both lights for general decorative applications and for safety lighting are manufactured industrially in large series. Escape route lights are legally required in public buildings, hotels, restaurants, airports, event rooms, etc. The inventive designs of the light variants without carrier discs for pictograms or safety signs can be used widely for decorative path lighting as well as for display case, furniture or counter lighting.

The solution according to the invention has numerous advantageous effects compared to the state of the art. A main advantage is that a modular system for a family of lights of different sizes is created by producing tools for a base profile, end caps, protective tubes for functional modules and optionally one or more side or additional profiles once, since only the length of the profiles and protective tubes determines the system size. The functional modules, which in the case of electronics in particular consist of circuit boards as carrier materials, are only determined by the smallest necessary size for different system dimensions and can always be used with this or adapted by simply changing the length of the circuit board with the same layout. This represents a significant saving in tool costs compared to solutions that require different housings and components for different sizes.

When used as an escape route light with a corresponding light guide disc arrangement made of a carrier disc with a pictogram, additional path lighting can be achieved very advantageously using additional functional modules with lamps arranged in side profiles. Partial luminous fluxes therefore do not have to be taken from the light guide disc arrangement to exit in the direction of the escape route; the luminous flux of the lamp assigned to the light guide disc arrangement can therefore be optimally designed with regard to the required luminance in the pictogram. Furthermore, this means that the luminous fluxes directed towards the floor can optionally be increased in a simple manner by additionally arranging lamps with the same lamp structure. With such flexible construction concepts for escape route lights, the requirements of the EN 1838 standard are also met, which requires a higher level of lighting for lighting in the area of safety facilities such as first aid stations or fire-fighting equipment than the escape routes themselves.

Furthermore, functional modules in which lamps are arranged can be constructed very compactly, since the necessary operating devices (power supplies, electronic ballasts) can be implemented separately within another functional module. One operating device can operate several lamps. The increased space required by the individual functional modules with larger system outputs can also be distributed over the length of the system. This is particularly true for battery modules arranged in rods in single-battery lights. This means that very elegant and compact profiles can be used even for large-area pictogram lights, which is beneficial for the good design of light housings.
Another advantage is that the luminaire housing can be used separately without a carrier or light guide plate, both for decorative lighting purposes and for pure path lighting, including in the area of safety lighting. This significantly expands the range of applications for a corresponding luminaire family without additional tool costs. The system can therefore be traced back to a pure floodlight application, whereby the modular principle allows a wide range of product variations by arranging additional side and/or additional profiles or design elements. Furthermore, the construction principle shown allows for minimized costs in production and maintenance, since the functional modules do not or only partially fit into the profiles during assembly.

They are fixed by the inner contours of the profiles without any additional tools, the end caps are the only assembly elements that prevent any displacement in the longitudinal direction of the profile.

The use of the latest light sources, such as cold cathode fluorescent lamps or LED arrays, not only have a pleasantly small design but also a very long service life of up to 100,000 hours, which requires very little maintenance from the user.

By arranging protective tubes to accommodate the functional modules, the luminaires can generally be designed in protection class II according to the European lighting standard EN 60598, despite the use of metal profile elements as the luminaire housing. From a safety point of view, a higher quality design is achieved and installation is easier than with standard products with metal housings of protection class I.

disc for pictograms, with two additional profiles arranged on the base profile as shown in Figure 9 and

Fig. 13 shows the design of an outer end cap of the floodlight shown in Figure 12, with additional moldings arranged on the base element according to Figure 7.

The luminaire shown in Figure 1 in a first embodiment as an escape route luminaire 1 with a single battery has a base profile 2 with end caps 10, wherein a light guide disc arrangement with carrier disc 3 and safety sign 4 is realized.

Cable elements 5 for suspended ceiling mounting are attached to the end caps 10. The mains connection cable 52 and the BUS or control cable 53 are fed through the cable ducts 18.

Figure 2 shows the escape route light 1 shown in Figure 1 without assembly elements and supply lines in a partially exploded view. In the base profile 2, according to the invention, the functional elements are divided into three functional modules and arranged in levels, starting at the bottom directly above the carrier plate 3 with the narrowest module for the light source, the lamp functional module 6, above that the battery functional module 7 and at the top the operating electronics functional module 8. The base profile 2 is made of aluminum, all functional modules are arranged in protective tubes 9 made of transparent, thin-walled polycarbonate. They ensure electrical insulation from the base profile and the mechanical fixation of the functional modules.

The base profile 2 also contains a gap-like contour 41, which serves to accommodate the carrier disc 3 for the safety sign 4 or other pictograms and thus as a light exit opening. The gap width of this contour corresponds to the thickness of the carrier disc 3. Both components are connected by means of screws or bolts 29 via lateral holes 44 in the base profile 2 and the carrier disc 3.

The end caps serve to close the base profile 2. They are made of a non-electrically conductive material, preferably thermoplastic such as polycarbonate. The same end cap is arranged symmetrically on each side of the base profile 2. They are constructed in two parts, consisting of an inner end cap 11 and an outer end cap 12. The inner end cap 11 lies directly on the front surface of the base profile 2, is connected to it by two screws 28 and bears on the outward-facing

On the opposite side is the contact unit 14 for contacting the functional modules with each other and with the lighting network and optionally required BUS or control lines.
The inner and outer end caps have common contours 25, which are symmetrical on both sides, for accommodating cable ducts 18 for the power supply cable and BUS or control cables. The cable is thus fed in on the top of the end caps, with cable ducts 18 arranged with a closed membrane, which can optionally be broken through when in use. The outer end cap 12 is firmly connected to the inner end cap 11 and the base profile 2 using four fastening screws 27.

During assembly or servicing, the mains connection terminal 19 and the terminal 20 for BUS or control lines are accessible after removing the outer end cap 12.

Figure 3 shows the sectional view of the base profile 2, which is equipped with the functional modules of an escape route light according to Figures 1 and 2. The protective tubes 9 are provided with corresponding inner contours 39, which serve to accommodate parts of the functional modules, in particular circuit boards, battery housings or other support systems. The inner contours 40 of the base profile 2 are formed by radii, webs and edges according to the external geometry of the protective tubes 9, so that these are fixed in their position without additional aids. Only the inner contours 39 of the protective tubes 9 are designed according to the geometry of the components of the functional modules. The base profile 2 always remains unchanged when using different components of the functional modules. Protective tubes 9 for functional modules of the same type always fit into the positions provided for them in the profile elements due to their identical external geometry.

Figure 4 shows a simplified circuit diagram of a first embodiment of the escape route light with individual battery shown in Figures 1 and 2 with regard to the functional division and electrical connection of the functional modules, wherein a first functional module operating electronics 8 comprises the electronic operating device for the light source (EVG) 47, the control electronics 48 and the charging electronics 49, a second functional module battery 7 comprises the rechargeable battery 50 with electrical lines 51,

a third functional module lamp 6, the light source 34 as a cold cathode fluorescent lamp with connecting cables 45 and connector 23 and a contact unit 14, the mains connection terminal 19, terminal for BUS or control lines 20, a light-emitting diode 30, a test button 31 and electrical connection technology 21 and 22 for functional modules to one another.

The mains voltage, the battery voltage, BUS or control signals as well as the electrical connections to the LED 30 and the test button 31 are forwarded from the contact unit 14 directly via a connector 21 to the operating electronics functional module 8. The LED 30 and the test button 31 are operated by the control electronics 48, the LED signals the operating state of the lamp, in particular the function of the charging management, the test button is used to test the battery operation.

The connecting cable 45 for the lamp operating voltage is connected directly to the operating electronics function module 8 and to the lamp function module via plug connector 23. The battery voltage is not directly connected to the operating electronics function module 8 via a plug connector 22, but is looped via the contact unit 14, so that the operating electronics function module 8 is completely de-energized when the plug connector 21 is removed. A common ground connection is also implemented for all low voltages and internal control signals.

Figure 5 shows the design of the inner end cap 11, which must be removed from the base profile 2 for servicing and maintenance, from the side that is accessible for establishing the electrical connections to the electrical installation when the outer end cap is removed. It carries the contact unit 14, a one-sided, non-plated circuit board 15, with the conductor side facing inwards. It is connected to the inner end cap 11 with three fastening screws 55. On the component side of this circuit board, the mains connection terminal 19 and the terminal 20 for BUS or control signals are present.
Furthermore, the LED 30 and the test button 31 are arranged, which protrude through the outer end cap for viewing and actuation purposes. On the conductor side, plug connectors 21 and 22 (see also Figure 6) are arranged, the counterparts of which in turn are to be connected to the function modules to be contacted or their connecting cables.

FREEFLEX GmbH, Ettenhausen ; ·♦:"■! ··."·*?..«.·. 18.02.01

can be found. The dimensions of the circuit board extend over the front surfaces of those functional modules that are to be contacted in the area of the base profile 2. The conductor tracks on the circuit board 15 establish the necessary connections between the connection terminals 19 and 20 and the connectors 21 and 22.

The inner end cap 11 is also designed with contours 26 for providing strain relief when using flexible connecting cables, as well as contours 25 for accommodating cable entries. The contours 25 are divided symmetrically with the outer end cap 12 (Figure 7).
For the implementation of internal wiring from the operating electronics functional module to the lamp functional module, openings 24 are provided both behind and below the circuit board 15.

Figure 6 shows the inner end cap 11 from the side that faces the base profile during assembly and is used to establish the electrical connections to the functional modules. The inner end cap 11 has corresponding openings 24 for the connectors 21 and 22 and for wiring, the dimensions of which are adapted to the connectors and cable geometries. Furthermore, the connector 21 is arranged as a touch-safe socket strip in surface mounting (SMD technology) on the conductor side of the circuit board 15. This means that the side of the circuit board 15 facing outwards (component side) remains free of dangerous contact voltages even without an additional cover. Furthermore, all live parts and contacts remain protected from contact even when the inner end cap 11 is removed from the base profile. By forcibly loosening the connector 21, the operating electronics functional module is separated from both the mains and battery voltage and safe servicing can be carried out with regard to changing the lamp or functional modules.

Figure 7 shows the outer end cap 12, which is trough-shaped, flush with the inner end cap, completely enclosing it and thus forming a functional space 13 for the contact unit 14. On the outside there are contours 17 with threaded insert 16 for rope suspension or connecting the light with additional fastening elements. At the same time, the threaded insert 16 can be made of conductive material.

FREEFLEX GmbH, Ettenhausen

The end caps on both sides are used to supply low voltage to the contact unit in two poles. This means that when mounted with conductive cable elements, low voltage operation of the light can also be achieved via an external power supply.

An opening 56 for the LED serves to identify it from the outside, the opening 57 allows the test button to be operated from the outside. The contours 25 for accommodating two cable entries are divided symmetrically with the inner end cap 11 (Figure 5).

Break-out contours 58, which are represented by a tapering of the lateral wall thicknesses, are used to open necessary wiring paths when arranging additional lateral fittings.

Figure 8 shows an exploded view of a particularly useful form of protective tube for a lamp function module 6. It consists of a two-part protective tube with an upper part 32 and a lower part 33 for accommodating the carrier plate 35. The cold cathode fluorescent lamp 34 used, e.g. with a length of 350 mm, determines the system dimensions of the lamp. The lamp sockets 36 are mounted on the carrier plate 35, which is designed as a circuit board, and the lamp is clipped into them so that they can be changed. The lamp voltage is supplied from a 2-pin connector 23 arranged on one side through corresponding conductor tracks on the circuit board to the lamp sockets 36. The two-part design of the protective tube makes it possible to change the lamp without having to remove the carrier plate 35 from the lower part 33. The upper part 32 is clipped onto the lower part 33 and can be easily removed and snapped back on. This means that the functional module can be used flexibly.

Figures 9 and 10 show a further embodiment of a multifunctional light according to the invention as an escape route light 101, in which parts that correspond to parts of the arrangement according to the first embodiment are marked with a reference number that is increased by 100. In this embodiment, in contrast to the first embodiment, two side profiles 37 of the same length are additionally arranged on the base profile 102. They are connected to the base profile 102 at corresponding tabs

42 screwed onto the top side. The base profile 102 has a contour 43 arranged on the top side on the left and right, which is set back slightly from the surface in order to accommodate the tabs 42 without exceeding the height of the base profile 102. In the base profile 102, the known functional modules of the first embodiment are arranged in protective tubes: battery functional module 108, operating electronics functional module 107 and lamp functional module 106, whereby the luminous flux of the light source 134 is coupled into the carrier disk 103 with safety symbol 104. A further lamp functional module 106 is installed in each of the side profiles 37 on the left and right, the luminous flux of these modules is directed towards the path area located under the lamp to illuminate it. The end caps 110 are functionally and structurally identical to the first embodiment, but are geometrically designed so that they cover the front contour of the entire system. This is achieved either by integrally forming the inner and outer end caps 111, 112 according to this geometry or by snapping additional elements onto the first embodiment of the inner and outer end caps 11 and 12 as shown in Figures 1 and 2 and 5, 6 and 7.
The electrical connection of the lamp function modules 106 located in the side profiles 37 with the operating electronics function module 107 is made at the front within the functional space of the outer end caps 112 by appropriate wiring and via plug connectors.

Figure 11 shows a further embodiment of a multifunctional light according to the invention as an escape route light 201, in which parts that correspond to parts of the arrangement according to the first embodiment are identified with a reference number that is increased by 200. In this embodiment, in contrast to the second embodiment, a further additional profile 38 is arranged at a distance below the base profile 202, which accommodates a lamp function module and the carrier disk 203 with safety symbol 204. This light guide disk arrangement is thus implemented separately from the base profile 202. The base profile 202 only contains the operating electronics function module and the battery function module.

The end caps 210 are again identical to the first and second embodiments in terms of function and construction and consist of an outer end cap 211 and an inner end cap 212.

, but are geometrically designed in such a way that they cover the front contour of the entire system. This is achieved either by integrally formed end caps of this geometry or by snapping additional elements onto the design of the end caps 10 as shown in Figures 1 and 2 as well as 5, 6 and 7.

The electrical connection of the basic lamp module located in the additional profile 38 with the operating electronics functional module is also made here at the front within the functional space of the extended outer end caps 212 by appropriate wiring.

Figure 12 shows a further embodiment of the multifunctional light according to the invention as a floodlight 301 for decorative lighting or as a path light without a carrier plate for pictograms, in which parts that correspond to parts of the arrangement according to the first embodiment are identified with a reference number that is increased by 300. Two side profiles 37 with lamps according to the embodiment in Fig. 9 are arranged on the base profile 302. The light exit openings are represented by the gap-shaped contours 341 in the side profiles 37 and in the base profile 302, the protection against contact with the lamps is always ensured by protective tubes of the lamp function modules, and the interior is also protected against the ingress of dirt. For suspended ceiling installation, corresponding cable elements 305 are attached to the outer end caps 312 with a fastening screw 354 each.

Figure 13 shows an outer end cap 312 of the floodlight shown in Figure 12, which consists of a base element as an outer end cap 12 according to Figure 7 and is supplemented with corresponding additional shaped pieces 46. The geometry of these additional shaped pieces 46 corresponds to the cross-sectional shape of the side profiles 37, thus completely covering them at the front. The additional shaped pieces 46 are connected to the base elements by means of an adhesive bond. The contours 58 in the outer end caps 12 as base elements are broken out in the direction of the front area of the side profiles 37 to guide internal wiring.

All the luminaire variants described are designed in such a way that they are suitable for the usual and previously described types of installation with the appropriate construction elements as accessories. These construction elements can be arranged in different places depending on their design, on the base profile 2 on the top by screwing in the area of the contour 43 or for ceiling mounting with cable suspension on the threaded pieces 16 of the outer end caps 12 with screws 54 as shown in Figures 1 and 7.
