SELV (Stable Voltage LED Strip)

Abstract

By the present application, for the length unlimited stabilized voltage LED light bar composed of multiple mutually continuous light emitting modules (10), the power / luminous flux of the LED light bar or LED light band (SELV) can be configured in terms of light emitting power on the entire length of the light bar by installing a cable / terminal / plug, or by spot bridging on various types of solder pads (2, 4, 5) that can be disconnected through a marked connection interface (11). Since the power / luminous flux of the LED light band (1) can be configured, for such stabilized voltage LED light bar with different power / luminous flux, there is no need to stock other models, and the inventory can be significantly reduced. In this way, the application flexibility of SELV can be significantly improved. For professionals, for the corresponding equipped luminaries, the luminous flux can also be very conveniently changed.

Description

[0001] The invention relates to an LED light strip according to the general idea of claim 1. In this way, the invention relates, inter alia, to a regulated LED light strip, in which the LEDs can be operated with different luminous fluxes / powers by means of an innovative connection configuration. Furthermore, the invention relates to a method for selecting a certain luminous intensity for a regulated LED light strip according to the general idea of claim 15.

[0002] The invention relates, inter alia, to a regulated LED light strip (in the following mostly only the abbreviation SELV will be used), which consists of a first, a second and n further serially arranged and mutually separable parallel light modules, each light module having a first internal daisy chain circuit for supplying power to the light module itself and to each of the second and n further light modules, each light module having at least one LED, usually a plurality of LEDs or similar components. The term "similar components" means that the invention is not limited to LEDs. Any other light source can likewise be used as a light-emitting component, for example laser diodes, OLED light-emitting components, incandescent bulbs or similar components, as long as they can be used as a light module of an LED light strip or a regulated LED light strip (SELV).

[0003] Furthermore, such SELVs are usually equipped with an electronic control system for these LEDs or similar components, which supplies the LEDs or similar components with electrical power during operation, with input and output feed lines for connecting the circuit to the supply voltage, wherein at least one cut-off point is present on each pair of input and output feed lines in order to cut the light strip between two light modules by means of a cutting tool, for example scissors or similar tools, so that each (separated) light module or all connected light modules can be connected to the supply voltage (individually) via its input and / or output feed lines if necessary.

[0004] These known cut-off points are used to shorten the SELV to the desired length in order to install it in a luminaire or on an object. If a SELV of the conventional type is cut at the cut-off point, the connected input feed line will be disconnected from the output feed line in principle. In other words, an input and output feed line that is connected together will become an output feed line that is disconnected at the first light module and an input feed line that is disconnected at the (second) further light module. In this way, from an electrical point of view, the input feed line and the input feed line are always at the same potential before cutting.

[0005] The state of the art is known as flexible or rigid LED strips (SELV) with typical supply voltages of 12VDC, 24VDC or 48VDC. The LEDs themselves and their electronic system are basically the same for all of these, but depending on the supply voltage used, LED strips of different power and required luminous flux are produced and stored. For different voltages, the number of LEDs can be different and the electronic system is adjusted accordingly. For example 3 LEDs for 12V, 6 LEDs for 24V and 12 LEDs for 48V. Depending on the actual model and voltage, the number of LEDs can also be increased or decreased - for example, some LEDs have a forward voltage of ~ 12V. Of course, LEDs can also be connected in parallel within the LED strip, especially when the supply voltage is low, in order to still achieve the same luminous intensity.

[0006] Flexible SELVs are connected together with two solder pads (ground "-" and voltage "+"), which are soldered together with a feeder or are connected by means of a card connector. Such card connectors are also often referred to as PCB plug connections.

[0007] As a standard, each light module of each SELV has an electronic current control device, which drives the LEDs of each light module or of each light segment (mostly 6-8 LEDs in series) with a predefined current. As described above, these individual light modules are arranged in parallel on the flexible strip, thus forming a strip consisting of LEDs connected to each other (series lighting), and are driven by a constant voltage.

[0008] On this basis, LED strips of specific models are used / stored depending on the power / luminous flux. The market (processor / end customer) selects different luminosities / luminous fluxes depending on the actual application - for luminaires, typical values are 600-4000 Im (lumens) per meter.

[0009] In March 2019, Tridonic GmbH & Co KG published and produced a luminaire of this typical type, which is called "talexx modul" and can be found at the following URL:

[0010] https: / / www.tridonic.ch / ch / products / talexx_module_lle_flex_g1_8mm- exc.asp .

[0011] Also in March 2019, Tridonic GmbH & Co KG launched the following SELVs with state-of-the-art technology: LLEFLEX G1 EXC with luminous fluxes of 600, 1200, 1800 and 2500 Im.

[0012] A typical construction can be seen in Fig. 11 (one of the drawings from the cited URL).

[0013] As can be seen in Fig. 11, there are three cut-off points per pair of input and output feed lines: one in the middle for soldered connections and two on the sides for connections by means of plugs. The present invention likewise adopts this practice and provides at least one or two cut-off points or, as shown in Fig. 11, three cut-off points. Likewise, the present invention provides different options for making connections, including soldering or plugs.

[0014] As a result, the current technology always produces SELVs in the same configuration, i.e. always for 6-8 LEDs / light modules. The typical length of such modules is 5 cm. Different powers are achieved by means of a specially programmed electronic circuit. This is always in units of the SELV model. For example, a luminaire manufacturer will keep a stock of two different power levels in units of 50 m of the length of the luminaire strip roll. For both models, the layout and the LEDs are identical, only the power supply for the LEDs (= power) is different, for which reason the electronic system of all light modules is configured differently at the time of delivery.

[0015] As a result, the standard practice is to always design light modules for the maximum power, but to determine the luminous power by means of a predefined power supply by means of production-technical intervention in the production of the SELV.

[0016] As a result, for different luminous powers, almost identical SELVs are produced, which must be kept in stock separately for different luminous powers.

[0017] The idea of achieving different luminous powers by means of a different voltage selection on the input side on the same SELV has not been successful. This is because, for different supply voltages on the SELV, a switching controller is required, which is not suitable for LED light modules.

[0018] This is because the switching controller is expensive, an additional component, and the dimming by means of pulse width modulation is poor (flicker can occur in certain ranges due to the impedance). In addition, the switching controller requires a capacitor, which shortens the life of the electronic circuit, and, in order to function at different voltages, different power supplies are required, which again increases the stock expenditure, especially for switching and DALI specifications. "DALI" stands for "Digital Addressable Lighting Interface". It is a communication protocol for building lighting and is used for communication between lighting control devices, such as electronic ballasts, brightness sensors or presence detectors.

[0019] Thus, in the field of SELV power / electronics, the technology used today has reached a balance in terms of technical performance, cost and lifetime.

[0020] The task of the present application is to increase the flexibility in the use of SELV, in particular without having to produce and store different SELVs for different luminous powers. This helps to reduce the inventory costs (inventory requirements).

[0021] The object of the present application is to produce a uniform light source, which can be set to the output power either by means of circuit measures at the factory or to different output powers at the site of installation, so that there is no longer a need to produce light sources of different powers.

[0022] In this way, the following advantages can be achieved: increased production quantity of SELVs, reduced inventory costs, increased flexibility in use.

[0023] This is becoming increasingly important, since with the new generation of LEDs, there is a requirement to very quickly adopt new LEDs and to eliminate older LEDs from the product range. If the number of inventory items can be reduced, this makes it easier to implement the above. In this way, the costs and resources can be optimized with the aid of the present application. This is becoming increasingly important, since the development process is very fast and dynamic.

[0024] The task is solved by the features of the independent claims. Preferred refinements are shown in the drawings, the drawing description and the dependent claims.

[0025] Other prior art SELVs will be explained in the following, but the prior art shown in Figure II is the most recent.

[0026] DE 20 2018 104 566 (Ul) - "Lighting device with dual voltage control capability" describes a lighting device with a skeleton and a plurality of light emitters arranged on the skeleton, designed as LEDs, and a conductor track arranged on the skeleton as well, for supplying the LEDs with electrical energy, wherein the conductor track has an interface which is connected to a contact point which enables the supply of energy, and the conductor track is arranged in such a way that the plurality of LEDs are connected to one another to form a block, which is associated with a current limiter, and in the block it is possible to supply all the LEDs of the block together, characterized in that, in order to be driven with a first voltage, the conductor track is arranged in such a way that the same blocks are connected in antiparallel and the two conductor tracks can be connected to one another by means of a bridge, which in turn forms a series connection of the blocks of LEDs, and in the case of a circuit arrangement which is bridged, it is possible to drive the lighting unit with a second voltage which is higher than the first voltage.

[0027] The structure in question does not concern a length- unlimited stabilized LED light strip or LED light band (SELV) without a flexible skeleton and with light-emitting modules arranged in series on it, which can be separated from one another in parallel; on the one hand, its modules or groups cannot be cut at an arbitrary cut-off point in order to obtain lighting strips of different lengths, and each cut-off point is not associated with a connection interface of a marker, so that the external power supply can be cut or established for the corresponding first module. In addition, for this known structure, there is a lack of current control means for the LEDs, which can lead to a difference in the light output of the LEDs that are further away from the supply voltage compared to the LEDs that are closer to the supply voltage.

[0028] In contrast, the task of the present application is to realize a length- unlimited stabilized LED light strip (SELV), which can be shortened to an arbitrary length with its light-emitting modules (groups) and in which the light output is the same on each module, regardless of the length (number of light-emitting modules), and after cutting the light-emitting modules from the unlimited light strip, the light output can be set in a simple manner.

[0029] FR 3048056 (Al) - "RUBAN LUMINEUX A DIODES ELECTROLUMINESCENTES" describes a light strip with light-emitting diodes, which can be cut at arbitrary lengths with a certain spacing distance, so that light-emitting modules of different lengths can be obtained. The individual modules are supplied with power by means of electronic current controllers, so that the light-emitting modules behind can emit the same light as the light-emitting modules in front. For the setting, conductive strips are arranged on different levels in the modules, and also at different positions, which can be closed at will in module units in order to produce different properties for each module. This means that, for a cut-off light strip, if an electrician wants to select a specific light output over the entire length, he has to select it specifically by means of a modification on each module of the cut-off light strip. As soon as this measure fails at any one position, the desired effect cannot be achieved over the entire length of the cut-off light strip. In addition to this, the cut-off or bridging points are located in the middle of the modules, so that the possible settings have to be made before the light strip is installed in a luminaire or similar luminaire, because after the installation, these positions are often no longer accessible.

[0030] In contrast thereto, the task of the present invention is to realize a length- unlimited SELV, which can be cut to any length (block) of its light modules (in short: modules) and which outputs the same light power on each module regardless of the length (number of light modules) and which, after cutting off a light module from the unlimited strip, can be set in a simple manner to the light power. In addition thereto, for a cut-off strip, the setting to the light power should be possible for the entire length thereof in its corresponding beginning.

[0031] EP 3 334 263 (Al) - "Printed circuit board, corresponding light module, light system and method for implementing a light module" describes a printed circuit board for a lighting module and a corresponding lighting module. What is involved here is not a SELV, which can be cut off indefinitely.

[0032] In contrast thereto, the task of the present invention is to realize a length- unlimited SELV, which can be cut to any length (block) of its light modules (in short: modules) and which outputs the same light power on each module regardless of the length (number of light modules) and which, after cutting off a light module from the unlimited strip, can be set in a simple manner to the light power. In addition thereto, for a cut-off strip, the setting to the light power should be possible for the entire length thereof in its corresponding beginning.

[0033] WO 2008 112 284 (Al) - "PERIMETER LIGHTING" describes a perimeter or edge lighting device for buildings, in particular with light emitting diodes as light sources. It is similar to EP 3 334 263 and consists of a distributed printed circuit board, but does not provide any guidance for the professional as to how a length- unlimited SELV should be designed, which can be cut off to different lengths and for which the light power can be set for the entire length in a simple manner for a cut-off strip. In this document, as published, however, resistors are used in order to control the current controller for the power of the LEDs. But if the light power desired is to be changed, the resistors have to be replaced in each module. This is feasible for a printed circuit board, but not for a length- unlimited flexible SELV with a flexible skeleton.

[0034] Therefore, the professional will not adopt the theory here.

[0035] EP3290787 (A1) - "A lighting device and corresponding method" describes an adjusted LED lighting module in order to achieve a specific luminous power. To achieve the goal, a switchable resistor is designed for each lighting module. This is not only complex, but also requires skill and repetitive operations for longer light bars. Furthermore, with this construction, the set luminous power can no longer be changed after the light bar has been installed in the luminaire, because the relevant parts can no longer be reached in order to switch the resistor. This prior art does not deal with any length-infinite SELV with switchable sections and does not provide any help for the professional in the further development of such light bars.

[0036] According to the invention, in addition to the switch-off point, as an innovation, the SELV has at least one pair of input and output feed lines and at least one marked connection interface, which, in contrast to the previously known switch-off point, allows the supply to the circuit to be disconnected or established there.

[0037] The marking is a technically necessary element in order to allow the luminaire manufacturer or the user to recognize the interface. The marking in the sense of the invention can be any measure in the area of the input and output feed lines, which allows the installer to recognize, close or disconnect the interface - for example by means of soldering or by installing a matching plug.

[0038] In this way, the luminaire manufacturer can now not only achieve a mechanical switch-off between the lighting modules (as in the past in order to adjust the length of the LED light bar to the length requirement in the luminaire), but also there the same can be influenced by means of a circuit measure, so that the following lighting modules do or do not receive a supply. If this is done by means of solder bridges or clamps, such measures are also reversible. That is, a selected setting can be changed back later.

[0039] On this basis, the widespread use of such SELVs can be achieved, by means of which for each lighting module (including in the unswitched state) the supply can be established or disconnected by means of a change at the marked connection interface.

[0040] Applications in this regard include the need to supply a SELV with a first supply voltage from one end of the SELV in a luminaire and to supply it with a second supply voltage (reverse voltage) from the other end of the SELV in order to avoid a voltage drop over the length of the SELV used or to let the lighting modules in the middle not produce any luminous flux, because the lighting modules on the left and right of the lighting modules in the middle already produce the required sufficient luminous flux.

[0041] For a better understanding, reference is made to the data sheet 12 / 18-LED307-14 of Tridonic GmbH & Co KG, which states that depending on the specific length of the SELV strip and the relative luminous flux required, the luminous flux will decrease due to line losses. For example, if a luminous flux of 1200 Im is chosen, the relative luminous flux will decrease at a length of 6 m. For a relative luminous flux of 1800 Im, this effect already occurs at a length of 4 m, and for a relative luminous flux of 2500 Im, this effect already occurs at a length of 2.4 m. Only at a luminous flux of 600 Im, the strip length can be almost 10 m.

[0042] By means of the present application, these lengths can be doubled to a certain extent, by feeding at both ends of the chain formed by the light modules and disconnecting the input feed in the middle of the chain. If later on the relative luminous flux needs to be reduced, the connection can be re-established and the feeding from the other end can be stopped. In this way, according to the present application, a change in luminous flux can be realized on the same SELV.

[0043] Also, for already installed luminaries, if it is intended to subsequently add other (not previously powered) light modules (respectively from the first light module towards the last light module of the same SLEV) or to remove light modules (respectively from the last light module of the SLEV towards the power supply), without damaging the basic construction of the SELV or the luminaries (by cutting the strip when removing, as a method that has always been used), the present application can also be used.

[0044] Due to the new connection interface with the marking, the stock of SELVs can be significantly reduced, which in turn can lead to a reduction of the stock capital, the stock space and the material depreciation of the old products that are no longer used. This is because the SELVs are currently upgraded approximately once a year. In this way, at the time of the upgrade, the stock products can be sold faster / destocked, which in turn can lead to a faster introduction of the new generation of products.

[0045] Preferably, at least one pair of the input and output feed lines, which are disconnected by the marked connection interface, has a primary part and a secondary part, wherein the primary part has a cut-off point and the secondary part is connected to the daisy chain of the SLEV. Each secondary part of the pair of input and output feed lines is connected to the circuit of the first light module and to each of the following light modules, in particular each secondary part is connected to each secondary part of the same type of the following light module, respectively. For a pair of input and output feed lines, if a connection is established or maintained between a primary part and a secondary part, the secondary side of each of the following pair of input and output feed lines is placed at the same potential as the secondary side of the input feed line associated with the preceding light module.

[0046] By disconnecting the primary and secondary parts and connecting the circuit to the corresponding secondary part, an automatic loop output to all following light modules can be achieved on the basis of an initially selected connection variant. In this way, a defined power supply for all light modules can be selected by a one-time connection at the beginning of a string of light modules, and the same power supply for LEDs and thus the same luminous power can be achieved for any electronic circuit by means of a one-time connection.

[0047] In other words: The luminous power of a complete (of any length) stabilized LED strip (SELV) can be set universally by soldering or clamping on the input and output feed lines or by removing a conductive strip or clamp, without any modification of the electronic control system itself.

[0048] If a connection with a plug is used, the configuration can be selected at the time of ordering or a design can be used which can be configured so that the luminaire manufacturer can configure a universal plug himself in order to select the input or output feed line as required. In contrast, soldering or desoldering is very simple and can be used in any operating environment, without being dependent on the delivery of plugs.

[0049] In addition to the various solder bridges / solder pads for "switching", as already mentioned above, a rotary switch can also be installed in the framework of the invention, or a rotary switch can be installed on the input feed line of the corresponding first light module, by means of which (in addition to the electrician or luminaire manufacturer, even the user) can switch between different power levels. Correspondingly, such a design is also included in the scope of protection, which uses not a solder bridge that can be removed or added, but a switching switch by means of which the electrical connection can be selected or cancelled.

[0050] However, it is noted here that the SELV should be stored in the manner mentioned above with 50 m rolls (or 5 m rolls). The cutting interval distance is typically between 30 and 100 mm.

[0051] It is further noted that the space on the SELV is very limited. In particular, with a minimized profile, the LED strip should be made uniform by means of an opaque cover (for example, width x height = 16 x 12 mm).

[0052] In this way, for this improved part of the invention, it is important that the LED strip can be cut with scissors as in the past and that the following input and output feed lines can be disconnected at the marked interface, but that the required lighting power for all the following lighting modules can be set at one time only at the beginning of each string of lighting modules. This operation is to be carried out as far as possible in one work step, which is unavoidable each time the SELV is connected to the power supply and which must therefore be carried out in any case (as in the past) by means of soldering or clamping.

[0053] On this basis, it is preferred that only the same type of stabilized LED strip (SELV) is prepared for storage, the function of which can be set arbitrarily by simple intervention.

[0054] It is preferred that the marked connection interface can be designed as a scratchable conductive bridge or as a breaking device for a pair of input or output feed lines, in particular between the primary part and the secondary part. The marking can be a painted or missing paint or a color marking, a marking on the SELV base material (plastic) or also a haptic marking, which can be designed as a protrusion or recess of the conductive strip material of the feed lines or of the like. Here, the marking can be located above the feed lines or below the feed lines or next to the feed lines.

[0055] It is further preferred that the solder bridge and / or the input or output feed lines can be designed as solder or as a material that is easy to solder or as a solder pad.

[0056] For the lighting module according to the invention, it is possible (as known) to design two pairs of input and output feed lines in order to connect the circuit to the supply voltage, one pair for the V+ connection and the other pair for the V- connection.

[0057] According to a refinement of the application, at least three pairs of input and output feed lines can be designed for connecting the circuit to the supply voltage, one pair for the V+ connection for each of the at least two separate circuits in the light module and at least two further pairs for the V- connection (or vice versa), wherein each of the at least two circuits is connected to the electronic control system, so that the control system can supply the LEDs differently depending on the voltage configuration of the circuit selected.

[0058] That is to say, when one of the two circuits is configured in the operating state by means of the electronic control system, a specific current is fed to the LEDs, when the other circuit is configured, another specific current is fed, and when both circuits are configured, a third current is fed to the LEDs. Here, the V+ connection remains unchanged, since it is always used as the V+ connection for the at least two circuits. If, however, the reverse design is used, the V+ connection changes and the V- connection remains unchanged.

[0059] Of course, it is also possible for each circuit to select the V+ connection individually (that is to say, each circuit has a separate V+ connection), which increases the number of lines on the SELV (or vice versa).

[0060] As an alternative to this version with different circuits, it is also possible to design only one circuit in terms of the power structure, which has different signal paths for V-, on which the same V- value or different V- values can be applied if necessary (or in the reverse structure the V+ values can be different).

[0061] With this refinement of the application, it is not crucial for the V- (signal) voltage to be the same, but rather that each electronic control system of each first light module receives a (voltage) signal which it can analyse uniquely, so that the control system can supply the LEDs of the first light module depending on this (signal) voltage or these (signal) voltages (for the reverse design, the V+ (signal voltage).

[0062] According to the preferred design of the application, each secondary part of an input feed line is connected to the circuit of the first light module and each light module located therein, or in other words, for any voltage signal configuration of a specific input feed line, if its secondary part loop is output to the secondary part of the input feed line of the next light module, the surprising effect occurs that, as soon as the required supply is determined on the first light module, all other light modules also have the same supply in the operating state without any measures being taken.

[0063] On the other hand, this means that, by using SELV, whose structure conforms to the present invention, different luminous power can be set on all luminous modules, for which only minor modifications are required on the first pair of input and output feed lines.

[0064] Of course, based on this principle, professionals can also perform mixed configurations. Specifically, this involves defining a specific power supply for the initial two light-emitting modules and then re-soldering the input or output feed lines of subsequent light-emitting modules to define different power supplies for that module and subsequent modules. Therefore, according to this invention, there are no limitations in terms of flexibility.

[0065] In this way, for such a design, the structure of the electronic control system should be such that it is connected to all circuits in each light-emitting module (or to all V- signal paths or vice versa). However, as an option, depending on the specific circuit or signal path selected, the required power supply to the LED can be selected by selecting (configuring or disconnecting) the corresponding connection interface, so that the same LED outputs a specific luminous power depending on the specific circuit or signal voltage path selected.

[0066] Within the electronic control system, whether this problem is solved through a distributed circuit structure or software, the specific solution should be left to the SELV or the electronic control system's process design, and is not the subject of this basic invention.

[0067] Next, combined Fig. 4-6 The accompanying drawings illustrate a specific and preferred design suggestion that is remarkably simple. For each circuit or each V-signal voltage path, a separate resistor is connected in series within or on the electronic control system. This allows the brightness (LED power) to be defined by the specific resistance value of the corresponding resistor or by the total resistance of the parallel resistors (in the case of contact closure at multiple connection points). Through this approach, the same design can be applied again for all light-emitting modules within the electronic control system itself, defining only the voltage configuration at the corresponding inputs of these control systems and their power supply operation to the associated LEDs or similar components.

[0068] In addition to resistors, other electronic components can also be used according to the present invention to send signals to the electronic control system for controlling the current.

[0069] For the SELV described above, a specific and preferred refinement consists in designing four pairs of input and output feed lines for connecting the circuit to the supply voltage, of which one pair is used for the V+ connection of the three individual circuits in the light module, and the other three pairs are used for the V- connection, wherein each of the three circuits is connected to the electronic control system in such a way that the control system, in the operating state, depending on the actual voltage configuration of the circuit, supplies the LEDs in different ways and selects the corresponding current in such a way that, in the case of use of the first circuit, a luminous power of 600 Im can be output from at least one LED, in the case of use of the second circuit, a luminous power of 1200 Im can be output from at least one LED, in the case of use of the third circuit, a luminous power of at least 1800 Im can be output from at least one LED, and preferably, in the case of simultaneous use of all three circuits, a luminous power of at least 2400 Im can be output from at least one LED.

[0070] As to how the electronic control system and the LEDs or similar components are designed by the expert according to the principles of the application so that they meet the requirements described, this is part of the technical basic knowledge of the expert and therefore does not have to be described here in more detail.

[0071] The application therefore also comprises a SELV according to any of the structures described above, which uses multiple circuits, of which all circuits have a common V+ electrode, which has no connection interface on its input and output feed lines, and only the V- electrodes of the individual circuits or the corresponding input and output feed lines of the V- connections have a connection interface each.

[0072] Here, preferably, the SELV according to the application is delivered with all connection interfaces connected and can be disconnected as required by scraping or by de-soldering. Alternatively, in the delivered state, all connection interfaces are disconnected and can be connected to a finished cable as required by soldering or by a pre-configured card connector (or switch), which, in the connected state, connects the paths between the feed line components, wherein, for the plug or switch, these are attached to the SELV in the delivered state.

[0073] Of course, the scope of the patent protection also includes the card connector or switch according to the above description or the finished connecting cable, which is designed in such a way that it can be used to selectively connect the connection points according to one of the features described above and with the marking.

[0074] For the finished luminaire manufacturer, preferably, according to one refinement of the application, both the cut-off point and the connection interface are marked by visible or tactile lines, wherein, as a preference, in order to better distinguish the cut-off point and the connection interface, the lines should be of a clearly different design.

[0075] From a practical point of view, according to the application, for SELV with more than two pairs of input and output feed lines, a power supply should be designed from a structural point of view such that each pair of input and output feed lines not belonging to V+ is associated with the same V- voltage, wherein, preferably, a resistor is connected in series behind the input and output feed lines, respectively, such that the V- potential or V- voltage is reduced by a specific value with respect to the electronic control system in the case of energization, or each pair of input and output feed lines not belonging to V+ is associated with a different V- potential, such that each circuit can be configured with different voltages, or the electronic control system obtains different V- potentials via input and output feed lines not belonging to V+ (or not belonging to V- in the case of the reverse design).

[0076] For the above design, the claimed scope of protection likewise also includes the following, provided that there is no significant difference in the influence of electrotechnical technology, namely, in addition to the multiple circuit, only a loop output circuit, which has a V+ and a V- connection for supplying all light modules, and in addition, at least one additional electrical line is laid, which is connected to the electronic control system on the one hand and loops out from the secondary part of the first pair of input and output feed lines to the next input and output feed line of the next light module on the other in order to apply at least one control voltage, wherein the electronic control system is designed such that the LEDs are supplied in another way without the application of the control voltage, which is different from the application of the control voltage.

[0077] The last-mentioned variant is refined in that two or more additional electrical lines are designed and / or all control voltages are V+ or V-.

[0078] For all the above variants, a simple and labor-saving solution / refinement is obtained if the primary sides of all the separate feed lines are at the same potential or connected to the same potential.

[0079] As a protective content, the invention also shows a method for selecting a specific luminous intensity for a SELV, by controlling the input current, in order to stimulate the LED to different luminous intensities, wherein a SELV is provided, which has multiple different circuits or multiple additional electrical lines in order to supply or activate an electronic control system, wherein for each circuit or each additional line a specific supply value for the LED is associated in the electronic control system and the circuit or the corresponding additional line, which matches the desired selection, can be configured with a supply voltage or with a control voltage, in particular by closing the open feed line by means of a solder bridge or by means of a pre-set card connector for the corresponding circuit or the corresponding additional line.

[0083] According to a preferred refinement, the marked connection interface can be designed as a scratchable conductive bridge or as a disconnecting device of a pair of input or output feed lines, in particular between a primary part and a secondary part.

[0084] Preferably, the solder bridge and / or the input or output feed lines can be designed in the form of solder pads or as a material that is easy to solder.

[0085] According to a preferred refinement, two pairs of input and output feed lines are designed for each light module for connecting the circuit to the supply voltage, wherein one pair is used for the V+ connection and the other pair is used for the V- connection, or at least three pairs of input and output feed lines are designed for connecting the circuit to the supply voltage, wherein one pair is used for the V+ connection of at least two separate circuits in each light module and at least two further pairs are used for the V- connection, wherein each of the at least two circuits is connected to the electronic control system, such that the control system can supply the LEDs differently depending on the specific voltage configuration of the circuit.

[0086] Preferably, four pairs of input and output feed lines are designed for connecting the circuit to the supply voltage, wherein one pair is used for the V+ connection of three separate circuits in the light module and the other three pairs are used for the V- connection, wherein each of the three circuits is connected together with the electronic control system, such that the control system in the operating state supplies the LEDs differently depending on the actual voltage configuration of the circuit and selects the corresponding current, such that in the case of use of the first circuit at least 600 Im of luminous power can be output from at least one LED, in the case of use of the second circuit at least 1200 Im of luminous power can be output from at least one LED, in the case of use of the third circuit at least 1800 Im of luminous power can be output from at least one LED, and preferably in the case of simultaneous use of all three circuits at least 2400 Im of luminous power can be output from at least one LED.

[0087] According to a preferred development, a multi-circuit is used, wherein all circuits have a common V+ electrode, which has no connection interface on its input and output feed lines, and only the input and output feed lines of the V- electrodes of the individual circuits each have a connection interface.

[0088] Preferably, the stabilized LED light strip has all connection interfaces connected in the delivered state and can be disconnected as required by scraping or by de-soldering, or, in the delivered state, all connection interfaces are disconnected and can be connected to a finished cable as required by soldering or by a pre-configured clamping connector, which, in the clamped state, closes the path between the feed line components, and such a clamping connector is attached to the stabilized LED light strip in the delivered state.

[0089] According to a preferred development, both the cut-off points and the connection interfaces are marked by visible or touchable lines, wherein, as a preference, the lines should have a clearly different design in order to better distinguish between cut-off points and connection interfaces.

[0090] According to a preferred development, the power supply is designed such that each pair of input and output feed lines not belonging to V+ is associated with the same V- voltage, wherein, preferably, a resistor is connected in series behind the input and output feed lines, respectively, such that the V- potential is reduced by a specific value relative to the electronic control system in the case of energization, or each pair of input and output feed lines not belonging to V+ is associated with a different V- potential, such that each circuit can be configured with different voltages, or the electronic control system obtains different V- potentials via the input and output feed lines not belonging to V+.

[0091] According to a preferred development, in addition to the multi-circuit, only one circuit is looped out, which has a V+ and a V- connection for supplying power to all light modules, and, in addition, at least one additional electrical line is laid, which is connected to the electronic control system on the one hand and looped out from the secondary part of the first pair of input and output feed lines to the secondary part of the next input and output feed lines of the next light module (10n) in order to apply at least one control voltage, wherein the electronic control system is designed such that, in the absence of the application of the control voltage, the LEDs are supplied in another way, which is different from the application of the control voltage.

[0092] Preferably, more than two additional electrical lines are designed, and / or all control voltages are V+ or V-.

[0093] Preferably, the primary sides of all separate input and output feed lines are at the same potential or connected to the same potential.

[0094] In addition, according to the application, a connector or finished connection cable is designed for selectively bridging the marked connection interfaces.

[0095] In addition, according to the application, a method is created for applying the second variant described above (but not limited thereto. That is, the method can also be applied in conjunction with the third and fourth variants described below), namely for selecting a specific luminous intensity for the stabilized LED light strip, in which, by controlling the input current, the LEDs can be excited to different luminous intensities, wherein a stabilized LED light strip is provided, which has a plurality of different circuits or a plurality of additional electrical lines for supplying or actuating the electronic control system, wherein for each circuit or each additional line a specific supply value for the LEDs is associated in the electronic control system, and the circuit or the corresponding additional line that matches the desired selection can be configured with the supply voltage or with a control voltage, in particular by closing the broken feed lines for the corresponding circuit or the corresponding additional line by means of a solder bridge or by means of a pre-installed connector.

[0096] According to the third variant of the application, the third variant is implemented, in which the current control circuit of each module can be actuated in different ways by means of a pre-installed impedance / resistor: Here, a stabilized LED is involved, which has

[0097] - a plurality of light modules that can be separated from one another and can form an LED light strip by being connected in series, which light modules have

[0098] - LEDs,

[0099] - an electronic control system for the supply control of the LEDs,

[0100] - at least two pairs of input and output feed lines for supplying the light modules, wherein each pair of input and output feed lines functions as a switch by means of a removable solder bridge,

[0101] - at least two resistors that can be connected in parallel to one another, which are connected to the current control circuit on the resistor input side in order to set the output current of the current control circuit, and thus the luminous power of the LEDs,

[0102] - wherein each resistor is connected in series with a separate input feed line on the resistor output side,

[0103] - wherein, in order to set the luminous power of the LEDs in all the following modules of the LED light strip, the input feed line loop in the first light module is output to the resistor input side of the corresponding next module,

[0104] - so that in the operating state the potential at the input side of the resistor is also automatically at the input side of the resistor of the next module which is not switched off.

[0105] For this third variant, the application can also be used, whether or not in a modular constant-voltage LED strip, so that the application also comprises a non-modular constant-voltage LED strip, in particular comprising

[0106] - input and (output) feed lines for connecting the voltage / supply

[0107] - an electronic current controller for supplying the next connected LED in a controlled manner, and

[0108] - a plurality of (regulating) resistors connected to the electronic current controller for actuating the current controller for outputting the current, wherein each (regulating) resistor is connected in front of an input feed line which functions as a switch by means of a solder bridge which can be removed, so that the solder bridge is selected for actuating the current controller. This technique is applied in all embodiments. Fig. 4-9 Compared to the known technique, this structure makes it possible to easily set the desired luminous intensity of the LED strip by means of solder bridges or by removing solder bridges. For a specially designed electronic current controller, the technique can also be adapted so that the current controller does not require an external resistor for actuation, but only a different signal input, as shown in Fig. 6. Fig. 10

[0109] There, not a certain specific impedance value is responsible for the actuation, but for each luminous power a separate signal input path is provided. Depending on the signal input path which is specifically actuated, the corresponding luminous power is output.

[0110] As shown in Fig. 6, for the current control circuit, this resistance-free actuation by means of a suitable signal input is applied in all embodiments of the application, if desired, by using a current controller which can be actuated by means of different signal paths instead of an electronic current controller which can be regulated by means of an external resistor. In this way, all embodiments according to the application can be designed with a resistance-actuated current controller or with a signal input path-controlled current controller. Fig. 10

[0111] In particular for the embodiments according to claim 1 and the modifications according to the dependent claims of this claim, according to the application, the structure shown in Fig. 6 can also be provided. Fig. 10

[0112] In other words, from Fig. 6 and Fig. 4 and 6 ​​​As can be derived from claim 9, the application also comprises a detachable stabilized LED strip having a plurality of light modules designed as segments, wherein each segment has at least one current control circuit, the output current of which can be specified by an external resistor connected to a corresponding input of the current control circuit, wherein, according to the application, the specified value can be selected by connecting a plurality of resistors to the input of the current control circuit, which, at the other end, can be individually or jointly influenced by the input voltage, for which purpose a broken voltage supply line is bridged.

[0113] For such a detachable stabilized LED strip, according to the application, it is further improved that each other end side loop output of each resistor is routed to the corresponding other end side of the corresponding resistor of the next segment or light module. By this measure, each next segment / light module automatically has the same resistor value as the previous segment / light module at its current control circuit in order to specify the output current of this current control circuit. In this way, it is ensured that the output current is defined only once at the current control circuit of the first segment / light module and is defined as the same value for all next connected segments / light modules. In this way, only a simple operation at the first segment / light module is required in order to determine a specific light power for a string of segments / light modules of any length. In this way, one raw material (one type of detachable stabilized LED strip of unlimited length) can be used to design luminaires of different light powers (e.g. different light colors or different light intensities).

[0114] In other words: For the luminaire manufacturer, the stock, ordering mechanism, delivery process and production process can be optimized to only one type of detachable stabilized LED strip of unlimited length. Depending on the specific requirements, the luminaire manufacturer can easily select and set the light power required.

[0115] If necessary, a reset can even be carried out later, by removing the solder bridge and re-establishing the solder bridge at another location. Likewise, a professional can set different light powers for each segment at a later time by the length of the detachable stabilized LED strip of unlimited length, by disconnecting the loop output other end side line for the next segments / light modules and simultaneously consciously machining a new solder bridge in another way at the first segment to be changed.

[0116] A fourth variant of the application is as follows - see patent claims 17-21:

[0117] According to the invention, a stabilized LED light bar is designed, which has a plurality of light emitting modules, which can be separated from each other and which can form the LED light bar by being connected in series, the light emitting modules having: LEDs, an electronic control system for supplying power to the LEDs, at least two pairs of input and output feed lines with connection interfaces for supplying power to the corresponding light emitting module, and at least two electrically conductive strips, which are connected to the electronic control system and to one of the pairs of input and output feed lines, respectively, wherein the input and output feed lines of the first light emitting module are looped out to the input and output feed lines of the following module, so that in the operating state the potential present on the input and output feed lines of the first light emitting module is also present on the input and output feed lines of the following module, and wherein, in order to set the light emission power of the LEDs in all modules, the potential present on the input and output feed lines of the first light emitting module in the operating state can be set by opening or closing the connection interfaces of the input and output feed lines in the first module.

[0118] Preferably, the connection interfaces separate the input and output feed lines into a primary part and a secondary part, respectively, wherein the primary part and the secondary part are electrically insulated from each other if the connection interface is in the open state, and wherein the primary part and the secondary part are electrically conductive if the connection interface is in the closed state.

[0119] According to a preferred refinement, the connection interfaces can be closed by means of a removable solder bridge or a coupling strip.

[0120] Preferably, in the delivered installation state and in the operating state of the LED light bar, all connection interfaces of the input and output feed lines in all modules are in the open state, and the light emission power of the LEDs has already been set in accordance with the potential present on the input and output feed lines without connection interfaces, which are connected together by means of the electrically conductive strips and the electronic control system.

[0121] According to a preferred refinement, in the operating state, in order to change the light emission power of the LEDs in all modules, one or both connection interfaces of the input and output feed lines can be closed in the first module.

[0122] Further advantages, features and details of the invention are described in the following description, in which embodiments of the invention are explained with reference to the drawings.

[0123] The list of reference signs and the technical content and the figures in the patent claims are part of the patent disclosure. The drawings are presented in a context-related and comprehensive manner. Identical parts are indicated by identical reference signs, and reference signs with different indices indicate functionally identical or similar parts.

[0124] Brief description of the drawings:

[0125] Fig. 1The image shows three light-emitting modules on a SELV, which have four solder pads and an electronic control system for regulating a constant current.

[0126] Fig. 2 It shows and Fig. 1 It has the same structure, connected to a single feed line, where solder joint bridging is achieved by selecting and fixing the feed line;

[0127] Fig. 3 The broken input and output feed sections are shown in enlarged detail images, where solder pad V- is broken from the "brightness control" solder pad;

[0128] Fig. 4 The illustration shows a specific design of a preferred embodiment of the SELV light-emitting module, which can be configured with three or four luminous fluxes;

[0129] Fig. 5 The design of a SELV with two light-emitting modules is shown, where each module can only select one luminous flux intensity, or cannot select the luminous flux intensity.

[0130] Fig. 6 It shows something similar to Fig. 4 The structure of the first light-emitting module is similar to... Fig. 5 However, according to the present invention, compared to Fig. 5 The wiring of its second light-emitting module is different;

[0131] Fig. 7-9 Each shows a similar Fig. 4 and 6 The embodiments are described, but different luminous fluxes are selected / set respectively, specifically as follows: Fig. 7 Light flux setting 1 Fig. 8 Light flux setting 2 and Fig. 9 The luminous flux setting is 3.

[0132] Fig. 10 An embodiment of an SELV with a light-emitting module is shown, wherein, due to the structure of the electronic current control circuit (6), three different luminous flux intensities can be selected without a pre-connection resistor, and

[0133] Figure 11 shows SELV using existing technology (from the URL cited at the beginning of this article).

[0134] Fig. 1A series of three light modules 10a-10c on a SELV is shown, which, as is known, has at least one cut-off point 7 between two modules 10. Likewise, as is known, each light module 10a-10c has a continuous input and output feed line 2. In the present case, these are V+. The LEDs 3 are shown by icons, which, in operation, are responsible for the supply by means of the electronic control system 6. According to the application, the input and output feed lines 2, 4, 5, as shown here, each have an additional marked connection interface 11, and this is in the open state. Thus, for the present embodiment, there is only one electrical line, and this is configured in units of light modules 10, specifically as a line 2 (V+). Such a SELV cannot light up. Even if a voltage V- is applied at 4.1 (first pair of open input and output feed lines), this cannot light up, since, due to the break in the connection interface 11, the voltage cannot be looped out to the following light module 10b or 10c. But if the connection interface 11 is closed by means of a solder bridge (not shown here), then, with the application of V-, the corresponding light module 10b or 10c can light up, and the luminous flux is based on the supply by the electronic control system 6, depending on the voltage information it obtains via the interfaces 4.1 or 5.1.

[0135] If the open feed lines 4.2 and 4.3 or their secondary sections 5.2 and 5.3 transmit other signals to the electronic control system 6, then this supplies in another way, and in turn produces a different luminous flux.

[0136] In short: By means of the application, it is possible to realize a selection of luminous flux in the light modules 10a-10c of a SELV, by simple wiring, so that the electronic control system receives a specific, changeable signal.

[0137] Fig. 2 The same structure is shown, but with the connection of the first light module 10a. Fig. 1 Here, the open input feed line 4.1 is closed by means of a solder bridge 9 with its secondary side 5.3, and this is connected together with a line 13 of the supply 8, which is also responsible for V+ to the continuous feed line 2.

[0138] In this way, in this structure, the light module 10a lights up with a specific brightness, which is defined by the brightness control on the solder bridge 9 (4.3-9-5.3) and in combination with its connection to the electronic control system 6.

[0139] Since no solder bridge is provided on the next light module 10b, it will remain dim, even if in the default case 4.3 or 5.3 and 4.3 of the output feed are connected together. According to the application, the open connection of the connection interface 11 prevents the electronic control system 6 of the light module 10b from being activated.

[0140] In the following, a special design of the application will also be described, in which, however, the input and output feed 5.3 of the first light module 10a and the input and output feed 5.3 of the second light module 10b are connected together (the other corresponding secondary parts likewise form an electrical connection with one another). In this case, for this design, if a solder bridge 9 as shown is present between the input and output feeds 4.3 and 5.3, the second light module 10b likewise receives an electrical signal on the secondary part 5.3, which is identical to that on the input and output feed 5.3 of the first module 10a. In this case, therefore, although there is an open connection at the connection interface 11, the LEDs of the light module 10b likewise emit light as the first module 10a.

[0141] Fig. 3 The part of the input and output feeds 4.1-4.3 or 5.1-5.3 that is broken away and the broken-away connection interface 11 are shown enlarged.

[0142] Fig. 4 The wiring of a specific embodiment is shown more clearly in a clear manner, it can be seen that, by means of the three resistors 12.1-12.3, different voltages are transmitted to the electronic control system 6 in the event of a corresponding signal being fed in. In the present case, as shown here in detail, V- can be connected to the supply voltage by means of the solder bridge 9 or by means of a pair of consecutive input and output feeds 2, with the result that the resistor Rl / 12.1 conducts V- to the electronic control system 6 and causes the electronic control system 6 to supply the LEDs 3 with power in a specific manner at the corresponding signal input of the electronic control system 6. At the marked connection interfaces 11.1 and 11.2, the connection is open, so that, although the input and output feeds 4.1 and 4.2 are at the same potential as the input and output feeds 2 mentioned (see the electrical connection between 2, 4.1 and 4.2), no signal is output to the input and output feeds 5.1 and 5.2 on the left of the light module 10. The input and output feeds 5.1 and 5.2 on the right are likewise not energized, since the potential of the input and output feeds 5.1 and 5.2 is output on the left by means of the conductive strips 14.1 and 14.2.

[0143] In contrast thereto, Fig. 5A much simpler SELV is shown, which basically corresponds to the prior art, with the difference that this SELV has a marked connection interface on the connection interface 11.2.

[0144] In this specific design, a solder bridge 9 is made on the left connection interface 11.2, while on the right marked connection interface 11.2, no such solder bridge 9 is made. At the same time, this structure (and Fig. 4 in comparison) also lacks the conductive strip 14, so that the input and output feed lines 5.1 on the left are not connected to the input and output feed lines 5.1 on the right of the light module 10a, so that in the circuit shown, the light module 10a can emit light, but the light module 10b cannot.

[0145] But if the marked connection interface 11.2 on the right of the light module 10a is closed at a later date, this also results in the light module 10b being supplied with power. This modification is reversible, so that this innovative SELV is flexible.

[0146] Fig. 6 The structure of Fig. 4 is the same in terms of complexity as the structure of and shows in particular how a signal is fed to the electronic control system 6 via the resistor 12.1, which in turn supplies the LEDs 3, but at the same time automatically supplies all light modules 10a and 10b accordingly, since the voltage for the electronics 12.1 is configured in all light modules 10a and 10b via the fixed connection on the conductive strip 14 and the connection point 15, so that each electronic control system 6 receives the same signal.

[0147] Fig. 4-9 In Fig. 8 a current regulator (LED driver) is shown by means of a symbol, for example Infineon BCR430U. In other words, a constant voltage is applied between "VS" and "GND SET1". The current driver is supplied with power via this. The desired operating current for the LEDs can be set via resistors R1-R3 (increasing resistance = decreasing current). The electronic control system 6 (a microcontroller) regulates the set current between VS (1) and REG (3). If now a voltage is applied between "VS" and "SET2" and the connection interface 11.1 is closed there (not shown here), then in another operating current for the LEDs can be seen.

[0148] The input and output feed lines (solder pads) or a plug must be designed in such a way that the solder bridges (for example GND and R2 connection) are created automatically as shown in Fig. 8 .

[0149] Fig. 7 is shownFig. 6 The structure described in the text is not visible, but the current path is clearly visible in the wiring there.

[0150] Similarly, in Fig. 8 As can be seen, since conductive strips 14 and 14.1 are charged, subsequent modules also obtain signals for the electronic control system 6 through resistors 12.1 and 12.2, which, by definition, results in another type of luminous power.

[0151] Fig. 9 It shows and Fig. 8 The same structure, but there, in the signal path connected to the electronic control system 6, it is resistor 12.3 instead of resistor 12.2. Therefore, as long as the resistance value of resistor 12.3 is different from that of R.2, it will result in a different luminous power.

[0152] In another variant, not shown, all two marked connection interfaces 11 are connected, so that all three resistors 12 are in use.

[0153] This invention will not affect the possible dimming function of SELV, because this function can generally be achieved through an external dimmer in conjunction with the electronic control system 6.

[0154] From an effectiveness standpoint, such a dimmer can also be considered an alternative to the present invention, but it incurs significantly higher costs on the user side because it is much more expensive and requires additional installation at the SELV lighting installation site. Furthermore, such a dimmer still suffers from several disadvantages in the field of voltage regulation: voltage-regulated dimmers are designed as pulse-width modulation (PWM) dimmers. Their disadvantage is that, for the same reason, they are sensitive to noise. This also applies to electronics, especially in video conferencing / video recording and audio recording, where such dimmers cannot be used due to the pulse-width modulation effect.

[0155] Fig. 10 An embodiment of a regulated LED light strip with a light-emitting module 10a is shown, wherein three different luminous flux intensities can be selected. The structure of the light-emitting module 10a includes LEDs 3 connected in series with LEDs 1-8, which are connected to the power supply wire V+ on the input side and to an electronic control system 6 on the output side. The electronic control system 6 is responsible for controlling the luminous power of the LEDs 3 and ensuring a stable luminous intensity based on the output current of the electronic control system 6. The electronic control system 6 is connected to the power supply voltage V+ on the input side and to multiple conductive strips on the output side. The output current of the electronic control system 6 can be set through the conductive strips. Specifically, in Fig. 10 In this context, the conductive bands are named as follows: GND, RS1, and RS2.

[0156] In the delivery and operation state, the output current of the electronic control system 6 is grounded through the conductive strip GND. In this state, LED 3 is driven with a power of 5.5W. The potential on the conductive strip GND is the same as the potential on the input and output feed lines 2 and the conductive strip 14. Since the conductive strip 14 loops out to the LED strip, the output side of the electronic control system of all the light-emitting modules of the LED strip (not shown) will have the same potential.

[0157] In order to change the luminous power on LED 3, Fig. 10 In the illustrated embodiment, the following options are provided. The output current of the electronic control system 6 can be changed by closing connection interfaces 11.1 or 11.2 on input and output feeds 4 and 5. This requires energizing either conductive strip RS1 or RS2. If conductive strip RS1 is energized, a different potential will appear on the output side of the electronic control system 6 compared to the delivery and operation states. With conductive strip RS1 energized, LED 3 will operate at 11W of power. Fig. 10 Above, the potential on conductive strip RS1 is output from the left input and output feeder loop via conductive strip 14.1 to... Fig. 10 On the right side, and for use by the input and output feed lines of all subsequent connected light-emitting modules (not shown), the electronic control system of the subsequent modules (not shown) has the exact same output current as the electronic control system 6 of the light-emitting module 10a. Thus, by closing or opening connection interface 11.1 or 11.2 on module 10a, not only can the luminous power of LED 3 be set on module 10a, but the luminous power of LEDs (not shown) in the subsequent modules (not shown) can also be set simultaneously.

[0158] Figure 11 shows a roll of SELV using existing technology and composed of multiple light-emitting modules. Below it, three marks indicate the cutting details on these light-emitting modules, so that different cutting operations can be performed on the SELV during the production of the lamp, thereby shortening it.

[0159] To summarize the optimal design in another way: e.g. Fig. 2 As shown, based on the specific connections of the feed lines on solder pads V+2 and V-4.x, a connection to the solder pad "brightness control (5.x)" can be established via solder joint bridge 9, through which the LED can be actuated with different power / luminous flux. According to the improvement, via the electronic control system 6 (also shown as a black box), the light strip 1 can be set to the corresponding power / luminous flux along its entire length, or in other words, also on each subsequent electronic control system.

[0160] Common subject matter as the minimum (widest) range covering all variants:

[0161] A length unlimited SELV LED strip or a length unlimited LED strip with a flexible skeleton and a first, a second and a n-th consecutive arranged and mutually separable parallel light module (10) of solid state light emitters and a matching driver circuit (6) or current control circuit and at least three pairs of input and output feed lines (2, 4, 5) for connecting the first light module (10) or the first and all consecutive light modules (10) to a supply voltage (8, V+, V-), wherein at least one cut-off point (7) is designed in each pair of input and output feed lines (2, 4, 5) across the length unlimited SELV LED strip or the length unlimited LED strip, by means of which the SELV LED strip (1) or the length unlimited LED strip can be cut between two light modules (10a, 10b) and

[0162] Two of the three pairs of input and output feed lines (4, 5) have at least one connection interface (11) with a marking and designed as a contact point next to the cut-off point (7) or the cut-off point, where the supply (8) of the first light module (10) or the n-th cut light module can be selectively arbitrarily cut off or established, so that the electronic current control system (6) can be connected to a certain input voltage at the selective input and in the circuit.

[0163] On the one hand, this construction allows the length unlimited SELV LED strip with flexible skeleton or the length unlimited LED strip to be shortened, fitted into a luminaire and then to select the voltage application to the conductive strip or to remove the operating voltage near the cut-off point (cut-off point). Depending on the specific wiring of the three pairs of input and output feed lines (2, 4, 5), different lighting effects can thus be achieved by means of a SELV LED strip or a LED strip. This allows the inventory to be simplified, but also flexibility in the installation of the luminaire.
