Light-emitting diodes, light-emitting diodes or LEDs designated light bulbs offer the possibility to produce flat and over the surface homogeneous light radiating headlamps in larger designs than surface lights with the names "Softlight", "Filllight" or brighteners in all areas of professional lighting, can be used as portrait lights in the immediate vicinity of a motion picture or video camera, in confined spaces, such as vehicles and staircases, and for the construction of light walls in the event and stage lighting.

From the EP 0 921 568 A2 For example, a lighting device is known in which a plurality of LED chips, which emit monochromatic light of different color, are inserted in recesses of a three-dimensional support of rectangular cross-section, electrically connected to conductor tracks and sealed with a transparent plastic. In the emission direction of the LED chips, a diffuser plate of transparent plastic consisting of microlenses for light control is connected to the three-dimensional support. The matrix-like combination of a plurality of arranged in the wells of the carrier modules with LEDs that emit monochromatic red, green, blue and yellow light with different color mixing and light scattering, leads to a lighting device with adjustable light color and light scattering.

The EP 1 134 849 discloses the features of the preamble. Object of the present invention is to provide a lighting system with light emitting diodes (LEDs), which emits light with variable color, brightness and radiation characteristics and modular is arbitrarily configurable and expandable.

This object is achieved by the features of claim 1.

The solution according to the invention provides an illumination system with light-emitting diodes, which emits light with variable color, brightness and radiation characteristics and can be modularly configured and expanded as desired. The modular configuration of the illumination system with light-emitting diodes allows either a compact or a large surface structure for an LED headlight or a LED surface light in conjunction with a suitable optics for bundling or widening the light emitted from the LEDs beams and for connecting to decentralized, the individual LED Associated control panels and / or a central, a plurality of interconnected LED panels associated control device for setting parameters such as light color, color temperature and chromaticity and brightness of the light emitted from the light modules of the LED panel light.

The illumination system has at least one LED panel, but preferably a plurality of at least mechanically, but preferably electrically and mechanically interconnected LED panels that a polygonal, preferably rectangular housing frame with one or more connection structures either only for mechanical coupling or mechanical coupling and electrical Connect with similar LED panels, a housing integrated in the frame integrated circuit board for receiving the lighting modules and arranged at the top of the housing frame receptacle for an optical device. The individual light modules integrated in the LED panel have the LEDs combined to form a light source, emitting light of different wavelengths, module electronics for driving the LEDs, a module carrier for receiving the LEDs and the module electronics, and a heat sink receiving the LEDs and connected to the module carrier on.

By extending the light module with one or more temperature and / or color sensors, which are arranged together with the LEDs in a compact form on a circuit board connected to the module carrier, is a self-sufficient electrical control and regulation of the light source formed by the LEDs by means of one Microcontroller having module electronics possible.

In a further refinement, optics for light mixing and / or beam shaping can be coupled to the lighting module. By arranging a plurality of lighting modules, the module electronics is connected to a higher-level control or regulating device, a controllable and controllable light source for a lighting device can be produced, which can be connected to other optical devices for beam shaping.

By selecting and composing the light of different wavelength emitting LEDs and their arrangement on the board of the light source and by a corresponding control of the LEDs through the module electronics, the light module can emit a light mixture whose parameters such as light color, color temperature and chromaticity in addition to the brightness of the emitted by the light module Light are adjustable.

With an individual control of LEDs emitting light of different wavelengths or groups of LEDs each emitting light of the same wavelength by the module electronics a targeted and independent of the temperature setting of the light mixture is ensured by the light emitted by the different colored LEDs light.

The module electronics equipped with a microcontroller make it possible to vary the control program for driving the LEDs or to connect the lighting module with a higher-level, external, i. to connect separate from the light module controller, so that the module electronics of the light module performs the entire control and possibly regulation of the self-sufficient light module and thus relieves the external controller.

The module electronics preferably control the LEDs as a function of the temperature and / or the power of the lighting module and / or the brightness and / or the color of the light mixture emitted by the lighting module in such a way that the LEDs emitting light of different wavelengths combine the brightness, color and chromaticity of the light mixture is constant, which allows local temperature compensation and a self-sufficient light module without the need or use of an external control device.

The underside of the housing frame is designed as a heat sink surface with cooling ribs, in which at least one receptacle for a form-fitting insertable connection element, is integrated in particular for a with a support member such as a tripod, a rig or the like, connectable pin.

The cooling body surface provided with cooling fins on the underside of the housing frame is connected to the heat sinks with the heat sinks receiving the LEDs of the light modules, so that the heat emitted by the LEDs is optimally dissipated via the cooling fins of the heat sink surface and light modules with high power can be used. The integration of receptacles for a positively insertable connection element in the heat sink surface, a compact design of the LED panels and their secure connection with a support element such as a tripod or a rig are guaranteed.

The arranged in the housing frame of the LED panel board has openings and fixtures for the lighting modules, a power supply and interface electronics for the lighting modules, a microprocessor for colorimetric calculations and a convection temperature compensation and arranged on side edges of the board and aligned perpendicular to the board connectors with a connection structure for the positive mechanical coupling and the electrically conductive connection. The board thus serves as a carrier for both the individual light modules of the LED panel and for the power supply device and interface electronics for electrical coupling of the light modules with a likewise arranged on the board microprocessor. The input and output connectors arranged on the side edges of the board allow the LED panel to be associated with further LED panels, with a control associated with a decentralized LED panel or a group of interconnected LED panels, and / or with a plurality of controls be connected by LED panels driving central power control unit.

The rectangular, in particular square, lighting modules are connected in a matrix-like lattice structure with a plurality of rows and columns with the board, the heat sink connected to the module carriers of the light modules used in openings of the board and good heat conductively arranged with the at the bottom of the LED panel Heat sink surface are connected, so that an optimal heat transfer from the LEDs to the heat sink surface is ensured and thereby the light output of the LEDs can be fully utilized.

In a preferred embodiment, the LED panel has a rectangular housing frame, the upper side of which can be connected to an optical device which has optics associated with the lighting modules and / or a common optical system which is common to all lighting modules.

To extend the illumination system, the LED panels are positively connected to each other at least on the narrow sides of their rectangular housing frame and a plurality of LED panels interconnected in rows via cross-links mechanically and / or electrically coupled to each other.

For an autonomous operation independent of an external power supply, an accumulator which can be coupled to the connection structure of at least one LED panel and is preferably adapted to the design of the LED panel can be provided which mechanically connects the LED panel connected to it or several with this LED panel and electrically coupled LED panels feeds.

For individual activation or adjustment of light parameters of the light modules of an LED panel, a plug-in to the connection structure of the LED panel and with the module electronics of the light modules of the LED panel electrically connectable control is provided after entering data or setting the parameters again can be disconnected from the LED panel. As a result, inter alia, a fine adjustment of the LED panels for emitting light with a desired light color and brightness and / or for different setting of the LED panels for generating light effects is possible.

In a preferred embodiment, the control has a tap changer with which a number of pre-programmed Lichteinstelllungen, so-called. Presets, can be set. This makes it possible, for example, for the user to pre-program certain, frequently used settings before the use of the LED panel at the filming location or in the studio, and then retrieve them quickly when needed, without the LED panels having to deal with more complex, larger and heavy ones HMI devices, such as DMX consoles or computers need to be connected. This is particularly advantageous when it comes to filming at tight locations, which may still be a high time pressure. Furthermore, the control still has a brightness controller and an on / off switch. Each setting on the control affects all electrically connected LED panels in the same way, so that even larger assemblies of LED panels with the control can be operated quickly and easily.

Furthermore, for power supply and data transmission, a plug can be plugged into the connection structure of at least one of the LED panels, which is connected via a cable for power supply and data transmission with another LED panel or with a central power control unit, so that larger lighting units from a variety of LED panels can be electrically connected to each other.

The connection structure is for mechanical connection of the LED panels, cross connector or connector preferably designed as a slide rail connection in the manner of a dovetail connection, a compound of a slotted box profile with a T-profile or the like with an end stop and has for the electrical connection of the LED panels, cross connector or connector spring contact pins and flat contacts on.

The central power control unit which drives a single LED panel or a multiplicity of LED panels preferably comprises a power supply and docking station with at least one connection for receiving a power supply and data transmission line to at least one LED panel and one connected to the power supply and docking station connected or connectable control device having a wireless and / or wired connection to the power supply and docking station and is connected via a plug-in receptacle with the power supply and docking station, so that an operation of the control unit both at the power supply and docking station and separated from the Power supply and docking station is possible and thus comfortable operation is ensured, for example, arranged at a higher height LED panels.

If the LED panel is to emit light only in a pre-programmed setting, a so-called "power adapter" can be connected to the LED panel or an LED panel group instead of a power supply and docking station and a control unit which has only one socket for the power supply to the LED panel or the LED panel group 1 '.

In an alternative embodiment eliminates the power supply and docking station and the controller takes over all control functions. In this embodiment, a data radio module is plugged onto each LED panel or each LED panel group, which communicates directly with the control unit, wherein the respective wireless model or LED panel or each LED panel group only power from a power supply or a battery is supplied and the data transmission is via radio.

If control via DMX 512, via a personal computer or via a serial interface desired, then the control unit continues to take over the communication, in which case a so-called system distributor is connected to the controller, which contains the necessary connectors and signal converter.

The radio modules can be set to different (hardware) channels, ie to different frequencies and (software) addresses, so that either several LED panels or LED panel groups are controlled simultaneously on the same channel or each LED Panel or each LED panel group is operated on a separate channel.

The receiving device of the LED panels for the light shaping optical device may consist of a arranged at the top of the frame connector, a tongue and groove connection or a magnetic device which is connected to the circuit board on the one hand and with the optical device on the other hand and a securely connect and disconnect the optical device to and from the LED panel.

The LED panel is covered on its light-emitting side either by an anti-reflective glass or has on its light-emitting side on a continuous plastic cover in which only the openings for the light-emitting LEDs remain free. These openings can in turn be covered with individual, preferably non-reflective glass panes.

The advantage of the continuous plastic cover with openings for the LEDs is in comparison to a large glass plate, which is sensitive to tension and shock loads, greater strength and the ability to attach a shield above the individual LEDs below the plastic cover, so that the susceptibility and Transmission of interference can be effectively reduced.

The rectangular housing frame of the LED panel is preferably formed as a plastic frame, which partially protrudes beyond the heat sink surface, so that the LED panel does not have to be touched on the hot heat sink surface, but can be used on the much cooler plastic surface.

The optical device can be made as soft optics with an array of reflectors formed by the individual light modules of the LED panels, in particular conical mirrors or parabolic mirrors, with a central opening which transmits the light emitted by the LEDs of the light modules into a full light guide inject. The light guide is used to mix the incident colored light and is preferably made of polymethyl acrylate (PMMA) or polycarbonate (PC). It preferably has a defined roughness at the top, or preferably regular structures such as e.g. At an angle of 120 ° milled triangular grooves to prevent at this point the total reflection back into the light guide and to facilitate the ride of the light rays upwards.

To increase the brightness and to improve the light mixture, the full light guide on the underside and on the sides is surrounded by a highly reflective cover or coating, which is preferably designed as a reflector plate, which also serves as a mechanically stable frame for the soft optics. In order to achieve a completely homogeneously radiating luminous surface, also at a small distance from the arrangement described, a diffuse plate or foil is fixed, which collects the radiated light from the full light guide and the side reflector sheets again, further mixed and evenly as a secondary source again radiates. With the described arrangement, it is possible to achieve a complete mixing of the light from the individual lighting modules at a comparatively low height.

With similar light emission of the individual LEDs of the LED panel can be dispensed with in the soft optics on the light-scattering plate with the openings provided therein and the reflectors used therein, since in this case a mixture of the light emitted by the LEDs light in the soft optics is no longer necessary. In this case, the soft optic preferably consists only of the highly mirrored plastic or sheet metal housing and the diffusely radiating plate, which is fastened to the LED panel, in particular by means of magnets adhesively bonded to the bottom of the sheet metal housing.

Alternatively, the optical device may be formed as a spot optic and arranged in a lens frame, the individual lighting modules associated lens systems comprising, in particular, consist of TIR lenses with attached honeycomb condensers.

The soft optics or the spot optics in turn can have magnets on which further optical accessories such as scattering films, scattering plates, straightening gratings or the like can be attached.

The LED panel 1 forms a luminous element, which in addition can be placed on top of the LED panel 1 soft optics 3 or spot optics 4 for an additional light mixing of the light of different wavelength and thus color emitting LEDs to a desired beam shaping is expandable. The LED panels 1 have lateral electromechanical plug connectors 13, 14, via which a plurality of LED panels 1 can be electrically and mechanically connected to form an LED panel row. By means of additional cross connectors 9, a plurality of LED panel rows can be combined to form an LED panel group 1 'with a matrix-shaped structure.

To a single LED panel 1 or to an LED panel group 1 ', a single control element 7 for decentralized control of the relevant LED panel 1 or an LED panel group 1' are plugged in and allows individual control or Setting of light parameters of the lighting modules of the relevant LED panel 1 or the LED panel group 1 '. The control element 7 can be disconnected from the LED panel 1 again after the entry of data or setting of the parameters.

For autonomous power supply, a single LED panel 1 or an LED panel group 1 'can be connected to an accumulator 10, which preferably likewise directly or via a connecting element to the LED panel 1 or the LED panel group 1'. is infectious.

A central power control unit 5, 6 serves to supply power to an LED panel 1 or an LED panel group 1 'and to input desired values for controlling the light modules 2 of the individual LED panels 1 and consists of a power supply and docking station 5 and a control unit 6, which can be plugged into the power supply and docking station 5 or operated via a radio or line connection separately from the power supply and docking station 5. The Stromver The supply and docking station 5 has a plurality of sockets which produce an electrical connection for power supply and control of the LED panel 1 or the LED panel group 1 'via connection cable 8.

In this embodiment, preferably all the LED panels 1 or LED panel groups 1 'are coupled in a star shape with power and data cables to the power supply and docking station 5.

In an in Fig. 2 shown overview of the individual functional elements of the modular lighting system according to the invention eliminates the power supply and docking station 5 in an alternative embodiment and the control unit 6 assumes all control functions. In this embodiment, a data radio module 18 is plugged onto each LED panel 1 or each LED panel group 1 ', which communicates directly with the control unit 6, wherein the respective radio data module 18 or LED panel 1 or each LED panel group 1 'only power from a power supply or a battery 10' is supplied and the data transmission is via radio.

The radio data transmission modules 18, the control unit 6, the decentralized control element 7 and the power adapter therefore have a jack socket into which a data cable can be inserted. If required, a software update (download) can also be carried out via this connection.

In the following, the structure and function of each in the Fig. 1 and 2 schematically illustrated functional elements of the modular lighting system and their interaction explained in more detail.

Fig. 3 shows an isometric view and Fig. 4 a plan view of an LED panel 1, which has a rectangular housing frame 11 with closed, designed as a heat sink surface 15 with cooling ribs 151 underside into which a circuit board 12 is inserted and connected to the narrow sides of the board 12 input connector 13 and output Connector 14 has. The circuit board 12 is mechanically and electrically connected to eight identically formed lighting modules 2. Between the arranged in two rows and eight columns lighting modules 2, three mounting magnets 16 are arranged, which are suitable for mounting an attachable to the housing frame 11 optical device in the form of soft optics 3 and the spot optics 4 according to Fig. 1 and 2 serve.

The rectangular housing frame 11 of the LED panel 1 is preferably formed as a plastic frame, which partially protrudes beyond the heat sink surface 15, so that the LED panel 1 does not have to be touched on the hot heat sink surface 15, but can be used on the much cooler plastic surface.

The soft optics 3 and the spot optics 4 may in turn comprise magnets on which further optical accessories such as scattering films, scattering plates, straightening grid or the like, can be attached.

In the underside of the housing frame 11 forming heat sink surface 15 three receptacles 152, 153, 154 are integrated, in which a connecting element can be used and positively connected to the LED panel 1 is connected. As a connecting element is used in particular a connected to a tripod, a rig or other support member or connectable connecting pin as he, for example, in the Fig. 30 and 31 is shown and described. The receptacles 152, 153, 154 are formed in the manner of a slotted box profile with and without additional groove, while the connecting pin has a corresponding T-shaped counter-profile, by attaching the connecting pin from the side of the housing frame 11 in the receptacles 152, 153, 154th can be used and locked with the LED panel 1 or secured by a clamping device.

A side view of the LED panel 1 is in Fig. 5 and shows on the left side a slider 17 for unlocking and left an output connector 14 with flat contacts and right an input connector 13 with spring contact pins, while at the bottom of the heat sink surface 15 with the cooling fins 151 and with the cross and T shaped recesses 152, 153, 154 for the insertion of a connecting pin, in particular a tripod pin, and in the middle of a thread for screwing the LED panel 1 on tripods, terminals and the like can be seen.

In the Fig. 6 shown bottom view of the LED panel 1 shows a plan view of the cooling fins 151 of the heat sink surface 15, on the left narrow side of the input connector 13 of the LED panel 1 and on the right sides the output of the LED panel 1 with the slider 17 to unlock the Connection of a connector or another LED panel. Seven circular or semicircular recesses 155, 156, 157, in which a in the recesses 152, 153, 154 inserted connecting pin during insertion and insertion positively into the recesses 152, 153, 154 engages.

The LED panel 1 can be optionally provided with a continuous, anti-glare glass or with a continuous plastic cover in which only the openings for the light-emitting LEDs remain free. The advantage of the continuous plastic cover with openings for the LEDs consists in the opposite to a large glass plate, which is sensitive to tension and shock loads, greater strength and the ability to attach a shield above the individual LEDs below the plastic cover, so that the susceptibility to interference and emission of interference can be effectively reduced.

Fig. 7 shows a perspective view of a light module 2, which consists of a square, designed as a printed circuit board module carrier 20, on which a module electronics is arranged and which has a recess 24 through which a surface of the module carrier 20 superior base 250 of a module heat sink 25 is inserted , and which is connected to the bottom with a connector strip 23, via which the module electronics with the decentralized control element 7 or the central power control unit 5, 6 is connected. On the base 250 of the module heat sink 25 is a light source 21 with a plurality of arranged on a cuboid metal core board, in this embodiment twelve LEDs 22, the pair of light of different wavelengths and thus color, a temperature sensor 28 and traces for connecting the LEDs 22 and the Temperature sensor 28 disposed to the edges of the metal core board, from where they are connected via a direct wire or bond connection with the module electronics.

This in Fig. 7 shown light module 2 is characterized by an optimal dissipation of the heat emitted by the LEDs 22 through the metal core board and the module heat sink 25 to the heat sink surface 15 of the LED panel 1 by a secure and simple mechanical connection between the light module 2 and a headlight housing or a Cooling device, wherein the module carrier 20 is not mechanically loaded and the light source 21 is arranged so that the beam path of the LEDs 22 is not disturbed by fasteners 26, 27 on the module carrier 2 or by the electronic components of the module electronics, not shown, so that the downstream in the direction of the light source 21 optics can capture the output of the LEDs 22 light rays and make it very effective.

For optimum dissipation of the heat emitted by the light source 21 in the operation of the light module 2, the heat sink 25 is made of a very good heat conductive material such as copper or aluminum and has on its underside a threaded hole through which a safe and simple mechanical connection the entire light module 2 can be made with the LED panel 1.

The connection of the module electronics with the decentralized control element 7 or the central power control unit 5, 6 and the power supply of the light module via the connector strip 23 on the underside of the module carrier 20, which has five contacts in one embodiment, with two voltage sources, a ground potential and with two contacts of a serial interface to the decentralized control element 7 or the central power control unit 5, 6 are connected.

The LEDs 22 are composed of a plurality of LEDs which emit light of different wavelengths, i. different colors, with multiple LEDs also having the same wavelength, i. Can emit light of the same color. By closely arranging the LEDs 22 on the metal core board, an adjustable by the selection of LEDs light mixture of the different colors is generated, which is still optimized by additional measures such as optical light bundling and light mixing and kept constant by other control and regulatory measures regardless of, for example, the temperature can be to adjust a desired color temperature, brightness and the like.

Fig. 8 shows a plan view of the board 12 of the LED panel 1, which is designed as a motherboard and has, inter alia, a controller and further storage, control and interface elements.
