Description

Lighting system

The present invention relates to a lighting system, in particular a linear lighting system, in accordance with the preamble of claim 1.

Such lighting systems are known, for example, from US 2007/0053209 A1 and US 2007/0190845 A1.

Linear lighting systems are used, for example, in the construction of boats for interior lighting of yachts, where they are arranged especially along spatial structures, such as steps on a wall. On the other hand, they represent a configuration element, through which lines present in the architecture can be accentuated. However, its object of application is not limited to the construction of ships. Other fields of application are, for example, interior architecture, in general, or elevated construction. In the interior structure, linear lighting systems are used for direct and indirect lighting, for example luminous lines as elements of graphic configuration for accentuation, such as luminous moldings, as light guidance systems or as security lighting, for example stairs stairs. In the high-rise construction, lighting systems are used in a linear fashion, for example, as facade systems, light lines, light guidance systems or mold lighting.

Linear lighting systems can be realized, for example, through luminous tubes arranged in a series. This represents, however, a high cost of assembly, since for a luminous tube an own support and a connection of own current is necessary. In addition, the luminous tubes have a limited longitudinal grid, and an overlap assembly is necessary in the area of the facade plinth.

Alternatively, such linearly luminous systems are made through luminous flexible tubes., These are flexible tubes of a light-transparent plastic material, in which luminous sources are integrated, such as incandescent lamps or diodes bright.

However, even in the case of the use of light-emitting diodes, from a certain light output, plastic flexible tubes can already be used due to the residual heat produced, since, on the one hand, they are only heat resistant to a certain extent. limited and, on the other hand, they cannot dissipate the heat of loss resulting from the light emitting diodes. This has a negative impact on the service life of both the light emitting diodes and the flexible tubes.

The light emitting diodes can be arranged alternatively on plates. However, these plates, like the luminous tubes, must be supplied with power individually and, therefore, require the same high assembly cost.

The present invention has the task of preparing a lighting system in a linear manner, which is suitable for a high light output, only requires a power supply over longer paths, allows flexible mounting locations of lighting elements as well as their individual activation and can be installed with reduced assembly cost.

The task is solved by means of a linear lighting system according to claim 1.

The lighting system comprises a mounting profile, which is configured for fixing on a substrate and for housing a power cable, a power cable, which is housed in the mounting profile and which is retained by it, and a lamp profile, which is configured for placement on the mounting profile. The lamp profile comprises a support trolley for lighting means, which is configured for insertion into the lamp profile and on which some lighting elements are placed, and contact pins for the electrical connection without tools of light elements with the power cord

The lamp profile is installed finished and can be handled separately. For fixing and electrical contact, the complete lamp profile is connected with the mounting profile and the power cable configured as a flat cable without the use of tools. The lamp profile can be disassembled and replaced, respectively, in particular by means of tools in a relatively simple manner.

Also in a critical assembly situation with narrow dimensions, simple assembly is possible, without tools and without contamination of the lighting system.

Many power supplies with expensive cable guides, such as in the case of very long light moldings based on standardized profiles, as are known from the prior art, are not necessarily necessary according to the invention. By virtue of the power cable drawn in the mounting profile of the lighting system, with a power supply a relatively long length of the lighting system is possible without the use of a plurality of lighting means. For example, they can be

connected or regulated up to three current circuits with corresponding lighting means. The use of LED units in the mounting profile after cleaning of the mounting location excludes mechanical damage to the LED modules that occurs frequently in practice. ESD (electrostatic discharge) damage due to false manipulation of the lamp profiles or of the lighting means or polarity change is excluded to the greatest extent possible. Failures of the lamp profiles or of the lighting means, for example due to cable breakage or poor corrosion contact connections, are excluded to the greatest extent possible thanks to the electrical contact in the power cable by means of plugs. contact. The insulation of the flat cable introduced through the contact plugs has regenerative properties and guarantees a lasting protection against corrosion of electrical conductors. The individual electrical occupation of the contact pins in accordance with the 4 phases of the flat cable allows flexible configuration of the possible light circuits. The tendency to pollution of the lighting system is reduced thanks to the smooth surfaces possible.

A mechanical elimination of glare is possible through the deepening of the support slots of the lighting means around a plane in the lamp profile. Many variants of LEDs known from the state of the art in a large number of power classes can be combined with the lighting system.

The very good cooling properties of the lighting system, conditioned by the multilayer structures, guarantee a constant luminous current and a long lifetime of the lighting means also in critical mounting situations. A lacquering of the lighting system is possible.

It is understood that the characteristics mentioned above and which are still explained below can not only be applied in any combination indicated, but also in other combinations. The framework of the invention is only defined by the claims.

The invention will be explained in detail below with the help of an exemplary embodiment with reference to the corresponding drawings. In this case:

Figure 8 shows a schematic perspective view of a medium supply for the lighting system according to Figure 1.

Figure 9 shows a schematic perspective view of an extreme power supply for the lighting system according to Figure 1.

The lighting system has a mounting profile 1, which can be fixed on a substrate, such as a wall, for example by means of screws or gluing. The mounting profile 1 can be in one piece or it can be made up of several juxtaposed pieces. The individual elements can be prepared in predetermined lengths. Through the custom cut of the individual elements in place a mounting profile 1 of discretionary length can be prepared.

The mounting profile 1 is configured in such a way that it can receive a power cable 10 for powering the lighting system with electric power. In the present embodiment, the power cable 10 is a flat ribbon cable with several conductors 11 that are arranged adjacent to each other and with an insulation 12 surrounding the conductors 11.

For retention of the flat ribbon cable 10, the side walls 2 opposite each other of the mounting profile 1 are provided with retaining ribs 3, which extend parallel to the bottom 4 of the mounting profile 1 which is

fixed on the substrate. The distance between the opposite retention ribs 3 is insignificantly smaller than the width of the flat ribbon cable 10, so that the flat ribbon cable 10 can be pressed between the retention ribs 3 on the bottom 4 of the mounting profile 1 and in this position it is retained by the retaining ribs 3, to secure it against falling. Additionally or alternatively, the power cable 10 may be glued on the mounting profile 1.

Although the mounting profile 1 consists of several juxtaposed individual elements, the power cable 10 can be a single continuous cable. It is connected with a device suitable for the supply of electrical power, for example with a power supply, a power supply, a regulator and / or a light control.

The mounting profile 1 is further configured so that it can receive a lamp profile 20. In the present embodiment, the upper ends of the side walls 2 of the mounting profile 1 and the side edges of the bottom 21 of the Lamp profile 20 is beveled and provided with projections 5, 22, so that the lamp profile 20 can be inserted through pressure in the mounting profile 1 and is retained through fitting the projections 5, 22 in mounting profile 1.

The side walls 23 of the lamp profile 20 are provided with at least one slot 24, which is intended for the accommodation of a support slot of the lighting means 30. In Figure 3, the side walls 23 are provided in each case with two slots 24, in which the support carriage of the lighting means 30 can be inserted.

The support carriage of the lighting means 30 contains a metal base plate 31, which is configured so that it can be inserted into the slots 24 of the lamp profile 20 and is retained by them. In the present embodiment, the central part of the base plate 31 is offset in height in front of the edges that fit in the slots 24, so that in accordance with the mounting position of the base plate 31 and according to in which slot 24 the base plate 31 is inserted, different distances from the upper side of the base plate with respect to the upper edge of the side walls 23 of the lamp profile result.

On the upper side of the base plate 31 a plate 32 is fixed, on which light diodes 33 are placed. Alternatively, instead of light diodes 33 other lighting means can also be used.

In the lamp profile 20, contact pins 34 are fixed. To this end, an end cap 36 is fixed at one end of the lamp profile 20. As is best deduced from the partially exploded representation arranged according to Figure 1, the end plate 34 is essentially in the form of a flat plate, in which recesses 37 are formed for the accommodation of the contact pins 34. Alternatively, the contact pins 34 may be otherwise fixed in the profile of lamps 20, for example, are insulated in holes in the base plate 31 of the support carriage of lighting means 30.

The number and distance of the contact pins 34 correspond in this case to the number and distance of the conductors 11 in the power cable 10. The contact pins 31 are sized and arranged in such a way that the contact tips 35 of the contact pins 34, during the elastic fit of the lamp profile 20, into which the support carriage for lighting means 30 is inserted, over the mounting profile 1, pass through the insulation 12 of the power cable 10 and contact the power cable conductors 11 10. In this way, a cable contact without tools is achieved.

Preferably, the conductors 11 of the power cable 10 are constituted by multi-stranded strands, so that the contact tips 35 can penetrate, as shown in Figure 3, the conductors 11. In this case, they displace the strands to the side and these are pressed elastically against the contact tips 35, thereby improving contact.

Preferably, the insulation 12 of the power cable 10 is regenerative, so that the holes generated through the contact tips 35 can be closed again.

According to the number and arrangement of the contact pins 34, different power circuits of the power cable 10 can be contacted. For example, in the case of two contact pins 34 all the light-emitting diodes 33 are connected to the same circuit of current and always generate the same color or white light. In the case of four contacts, the light-emitting diodes 33 can be connected with three different current circuits (with common return conductor) and in this way they can be controlled, for example, separated into three groups. In the case of separate activation of the three basic colors red, green and blue, RGB discretionary colors can be generated, for example. But four contact pins can also be used especially for power supply (2 contact pins) and as a data bus (2 contact pins), so that an intelligent circuit on the board 32 evaluates the data transmitted on the bus and correspondingly activate the light-emitting diodes 33.

The upper end of the contact pins 34 is configured for connection with the plate 32, either through coupling on the plate 32 or through welding on the plate 32. The upper end of the contact pins 34 can be connected , for example, through a wire plug or a curly cable or a tinned connection with the plate 32.

For the protection of the light-emitting diodes 33 and of the plate 32, a suitable cover 40, for example of light-transparent plastic, which is placed in the lamp profile 20, for example, by means of an elastic fitting on the profile, can be provided of lamps 20, as shown in figure 3.

The end caps 36 and the cover 40 may be configured such that the lamp profile 20 is waterproof.

The plate 32 can pass over the entire length of the support carriage of the lighting means 30 or it can be made up of individual plates. In the case of juxtaposition of several plates 32 on a support carriage of the lighting means 30, the electrical connection of two adjacent plates can be established through contact bridges 50.

As can be deduced from Figure 4, a contact bridge 50 comprises a body 51, which is made of an insulating material, such as plastic. The shape of the body 51 consists essentially of a flat plate, in which two elastic fitting elements 52 are connected laterally. The elastic fitting elements 52 serve to fix the contact bridge 50 and are configured in such a way that the bridge of contact 50, as shown in Figure 5, fits elastically, during placement on the plates 32, in retaining elements of the lamp profile 20 and is retained in this way. Alternatively, the elastic fitting elements 52 may also be configured such that the contact bridge 50, as shown in Figure 6, fits into retaining elements of the support carriage of the lighting means

30

As can be deduced from Figure 4, the contact bridge 50 also has contact plates 53, which elastically contact the adjacent plates 32. The contact sheets 53 are individually isolated and separated from each other. The sum of the width of a contact sheet 53 and the distance with respect to the next contact sheet 53 may be less than the width of the corresponding contact surface on the plate 32, so that several sheets can contribute to the transmission of current to or from a contact surface and the same contact bridge 50 can be used in a flexible manner for contact surfaces of different width and positioned differently.

Preferably, the contact bridge 50 further comprises a centering element 54 for positioning in the correct position and as a mounting aid between the plates 32. The centering element 54 may be at the center in the gap between the plates 32 and can fit asymmetrically on a correspondingly configured end (holes or grooves) of the plate 32.

In addition to the electrical connection of adjacent plates 32, these contact bridges 50 can also serve at the same time for fixing the plates 32 on the support carriage of the lighting means 30 and enable compensation of the different thermal longitudinal expansions. In addition to the electrical connection of adjacent plates 32 of the same support carriage of the lighting means 30, these contact bridges 50 can also be used for the connection of adjacent plates 32 of support carriages of the adjacent lighting means 30.

In addition to a connection of the power cable 10 with a power supply through usual means in the electrical installation (terminals, screws, etc.), the power supply can alternatively be carried out in one of the following ways.

Figure 7 shows a corner connector 60, comprising an insulating housing 61, the profile of which is configured corresponding to that of the mounting profile 1, so that the corner connector 60 can connect two mounting profiles 1 that extend in right angle to each other. At the bottom 62 of the housing 61, bands of conductors 63 extend, with which the contact pins 64 are connected. The number and distance of the contact pins 64 are selected according to the number and distance of the conductors 11 of the power cable 10. The contact pins 64 have, like the contact pins 34, contact tips which, when the power cable 10 is inserted, pass through the insulation 12 of the power cable 10 and contact without tools with their conductors 11. In this way, a power cable 10 can be supplied with power in a first mounting profile 1 from another power cable 10 in another adjacent mounting profile 1, or a conductive coupling can be made of electricity for power supply and / or for data transmission between several power cables 10. The angle between mounting profiles 1 is not limited by this case at 90º shown in the example. There is also the possibility of configuring the corner connector 60 flexibly adjustable in its angularity. Since the contact of the power cable 10 is made from the bottom 62 of the corner connector 60, the lamp profiles 20 can be extended continuously without seam, so that a continuous light line can also be generated at the edges. From

alternatively, the corner connector 60 can also be configured, like the lamp profile 20, for the elastic coupling on a corner formed by two mounting profiles 1 that join together at a discretionary angle.

Figure 8 shows a central supply 70, comprising an insulating housing 71, whose profile is configured in accordance with that of the mounting profile 1, so that it can be inserted between two adjacent base profiles 1. In the housing 71, contact pins 72 are arranged, the number and distance of which are selected according to the number and distance of the conductors 11 of the power cable 10. The contact pins 72 have the same contact pins 34 , contact points which, when the power cable 10 is inserted, pass through the insulation 12 of the power cable 10 and without tools contact the conductors 11 of the power cable 10. The ends of the contact pins 72, which are opposite to the contact tips, they are connected with conductors of a power cable 73, which is connected in a discretionary power supply. In this way, the power supply can be made from a place in the lighting system that can be determined in a discretionary manner, in which the central power supply 70 is inserted between two adjacent mounting profiles 1. Since the contact of the power cable 10 is made from the bottom, the lamp profiles can extend seamlessly, so that also in the edges a continuous light line can be generated. If the power cable 73 is provided at both ends with a housing 71 with contact pins 72, the power can also be supplied from a lighting system to another lighting system as a bridge. Alternatively, the central supply 70, the same as the lamp profile 20, can also be configured for the elastic coupling on a mounting profile 1.

Figure 9 shows an extreme power supply 80, comprising an insulating housing 81, which is configured for placement on one end of a power cable 10. In the housing 81 are arranged contact pins 82, whose number and distance are selected according to the number and distance of the conductors 11 of the power cable 10. The contact pins 82 have, as well as the contact pins 34, contact tips, which contact the conductors 11 of the power cable without tools feeding 10.

The present invention, for which an embodiment has been described as a non-limiting example, conditions a lighting system in a linear fashion, in which, through pressure of the lamp profile 20 on the mounting profile 1, it is made thereto. time a mechanical fixation and an electrical connection. The electrical contact is made in this case without tools.

For each lamp profile 20 it is not necessary to prepare a power supply of its own, but rather a continuous power cable 10 serves to feed a discretionary number of lamp profiles 20 inserted into the mounting profile 1. In this case, the total power is limited by the cross section of the conductors

11. The power cable 10 is protected by insertion in the mounting profile 1, which in this case serves as a cable channel.

The residual heat of the light emitting diodes 33 can be dissipated well through the metal base plate 31 of the light support carriage 30, so that high light performance can be achieved. If necessary, additional cooling ribs may be placed in the light carrier 30 or in the lamp profile 20. The dimensions of the lamp profile 20 can also be adapted to different light performance.

Through the modular structure with lamp profiles 20 of different lengths, which can be inserted in discretionary places in the mounting profile 1, the lighting system can be constructed and modified linearly in a flexible manner. The lamp profiles 20 can be juxtaposed seamlessly or also at intermediate distances. A subsequent modification of the positions and / or an addition or a removal of lamp profiles 20 is also easily possible.

In this case, different variants of lamp profiles 20 can be used, for example with diffusers or lenses, which are placed in front of the light emitting diodes 32. According to the position and the mounting depth of the support carriage of the means of lighting 30 different positions of the light-emitting diodes 33 are achieved, so that different angles of radiation and / or light damping can be achieved.

In this way, the present invention prepares a linear lighting system, which can be constructed flexibly and can be easily mounted.
