- the LED illuminant 2 has a white LED 4 as a light source, which is mounted on a housing 5 and is laterally surrounded by a reflector 6 for beam guidance.
- a white LED 4 as a light source
- mechanically flexible contact legs 8 each of which has a permanent magnetic base 9, lead out of the housing 5.
- the feet 9 thus serve both for the electrical contacting of the LED lighting means 2 and for its detachable fastening.
- the unit comprising the housing 5 (with control 7), the LED 4 and the reflector 6 can also be referred to as an LED module 2a.
- the flat carrier 3 has electrical contacts 11, 12 embedded in a carrier material 10, the surface 13 of which is exposed and thus serves as an electrical contact surface and as a mounting surface for the feet 9.
- the contacts 11, 12 shown have a different electrical potential, so that electrical power for operating the LED 4 is tapped from the lighting means 2 via them.
- the contacts 13 are designed in their function as attachment surface 13 so that the magnetic feet 9 can adhere to them flat.
- the contacts 11, 12 preferably have a permanent magnetic material; which has a magnetic polarity on the contact surface 13 which is opposite to a magnetic polarity of the associated foot 9.
- the contacts 11, 12 are magnetically polarized opposite to one another with respect to their contact surface 13 for aligning the LED illuminant 2.

- a foot 9, which is to be connected to a positive electrical potential has a negative magnetic polarity on its contact surface; and a foot 9, which is to be connected to a lower electrical potential, has a positive magnetic polarity on its contact surface.
- correct electrical polarity can be ensured, especially when the LED illuminant 6 is operated with direct current, since if the LED illuminant 2 is incorrectly oriented, its feet 9 and the contacts 11, 12 repel each other and only attract each other if they are correctly oriented.
- the magnetic polarity is shown with the symbols '+' and '-'.
- the Contacts of the carrier 3 or the feet 9 a ferromagnetic material, in particular an iron material such as steel.
- the LED light source 2 can be contacted in a particularly simple and space-saving manner.
- the reflector 6 can be covered by a transparent cover 14 to protect the light-emitting diode 4.
- the control circuit 7 can be designed as a driver for the light-emitting diode 4, in particular when the contacts 11, 12 are operated in alternating current.
- the control circuit 7 can also have various other functions, for example a dimming function, when activated, the luminosity of the LED 4 is specifically reduced.
- Another possible function is the use of color-variable illuminants a change in the luminous color of the illuminant, e.g. B. when using an LED color cluster of differently colored, individually controllable LEDs.
- control circuit 7 has a receiving means 15 with a radio antenna for receiving wirelessly transmitted radio control signals.
- the receiving means 15 is communicatively coupled to the control circuit 7 so that the control circuit 7 can convert the control signals.
- the control 7 is also selectively addressable, that is to say that it implements commands that have a matching identity code and does not implement commands that do not have a matching identity code.
- LED lamps 2 or groups of LED lamps 2 with the same identity code can be controlled in a targeted manner.
- groups of same-colored light-emitting diodes or lighting means can be selectively controlled, for example to change the color impression of the system, e.g. B. by switching on and / or switching off light sources of a certain color.
- FIG 2 shows the carrier 3 in a comparison to the view from FIG 1 a wider section with six contacts 11,12.
- the six contacts 11, 12 are connected to a DC voltage source 16 in such a way that they form a first group of contacts 11, which are connected to a positive pole of the DC voltage source 16, and a second group of contacts 12, which are connected to a negative pole of the DC voltage source 16 are connected.
- Each LED illuminant 2 magnetically adheres with its connections to a pair of contacts from the first group and the second group. The LED lighting means 2 are therefore connected electrically in parallel.
- a control circuit (not shown here) for controlling the lighting means 2 connected to the carrier 3 can be connected to the carrier 3.
- a dimming function can be provided via this control circuit, which energizes all contacts or a selected subset of contacts to a lesser extent.
- Providing a dimming function on the support instead of on the lighting means has the advantage that dimming can be implemented using only one control circuit and is therefore particularly cost-effective.
- the controls 7 can work selectively by only converting control signals which are provided for the specific lighting means.
- one of the lighting means 2 shown may dim down the luminosity in response to a data signal provided with a specific identity code, while another of the lighting means 2 does not respond to the dimming command.

- the control then preferably has a corresponding data readout function, e.g. B. a decoder.
- the contacts 11, 12 can also be connected differently.
- Another type of power supply can also be used, e.g. B. an AC voltage source.
- the carrier can be equipped with a suitable power supply unit, e.g. B. with a transformer for converting mains voltage into a supply voltage, if necessary using a rectifier.

- the contact surfaces 18 of the feet 9 of the LED lighting means 2 are exposed, that is to say that the contact surface 18 of the respective electrical connection 9 is exposed in the area of the flat underside.
- a luminous means 2 encapsulated in this way has the advantage that it can also be applied to a carrier as bulk material, in particular if the luminous means has a small dimension. Because of the round basic shape, the illuminant 2 can roll on the carrier until it rests on the flat underside and is then held on the carrier by the magnetic adhesive force. This is particularly advantageous if the magnetic polarity of the contact surfaces 18 of the feet is different and correlates with an associated magnetic polarity of associated contacts of the carrier, as described above, for example. Because then it is ensured that the feet 9 only put on suitable contacts of the wearer, for. B. connected to different connections of the (DC or AC) voltage source.
- the shape of the encapsulation is not restricted and can, for example, be cuboid, disk-shaped or cylindrical, which can be achieved in particular by appropriate encapsulation. Encapsulation can also can be achieved by using capsule shells, but their assembly is comparatively complex.

- each pair has a contact 32 of a first group and a contact 33 of a second group, an electrical potential being able to be applied between cross-group contacts.
- This arrangement has the advantage that it enables a high degree of flexibility in the control of the contacts 32, 33, since each pair of contacts 32, 33 can be easily identified and in extreme cases can have an individual power connection, e.g. B. a constant current source. Then an associated LED light source z. B. manage without their own control.
- FIG 9 shows a carrier 34 with several pairs of differently shaped contacts 35,36; 37.38 and 39.40, respectively.
- three pairs of groups are arranged in the same basic pattern on the carrier 34, the contacts 35, 36; 37, 38 and 39, 40 of each pair group have the same shape, which differs between the groups.
- different types of lighting means can be used, which can then be controlled and / or supplied in particular in a group-specific manner. So the contacts of a first couple group, e.g. B. with the rectangular contacts 35,36, to a different power source with a higher supply voltage than the second group of pairs with the triangular contacts 37,38.
- the third pair group with the round contacts 39, 40 may in turn be controlled differently and / or supplied from a different source.
- the contacts of a pair group may be matched to the connections of lamps with the same radiation characteristics, e.g. B. on LED lamps of the same color. Then, by group-selective control of the contacts 35 to 40, a luminosity of a color can be set individually. In order to rule out an incorrect assignment of light sources to contact pairs, the contact surfaces of the contacts and the associated connections may be shaped in such a way that they only fit one another.
- a “detachable light module” means a light module that can be manually attached to, detached from, or repositioned on the carrier without the use of tools or the need for permanent, hand-made electrical connections such as a connection that by a screw, splice, screw-wire connector, etc.

The spring contacts will improve the heat transfer away from the module and improve the module stability especially where the path / channel contacts between the module and the carrier are narrow.
- a light module may be designed in such a way that it can be magnetically attached to a carrier securely even if the surface of the carrier is curved.

- one half of the support 1140, ie, a hemisphere may be used using the same principles as those in FIG Figures 16A and 16B shown.
- FIG 16B shows the concept that electrical power may be delivered from the interior of the carrier of the lighting system to the carrier channels.
- Various electrical control devices such as ballasts, dimmers, transformers, power supplies, inverters, drivers, controllers, etc., may also be located in the wearer's body so that the lighting system may be connected directly to a standard power source, such as 110 volts AC.
- control devices may each operate one or more lighting modules, such as a ballast which operates four or eight fluorescent lighting modules.
- This feature of the disclosure may be associated with three-dimensional supports, e.g. B.
- a cube, a sphere or a polyhedron can be used, and it may also with two-dimensional supports, such as those in FIGS FIGn 10 , 14th and 15th can be used by extending the electrical channels to the inside of the support bodies rather than directly to the external connections as shown in the drawings.
- FIG 17A and 18A additional examples of embodiments of three-dimensional supports.
- FIG 17A FIG. 11 shows an icosahedron support 1180 having twenty equal faces 1182, each of which is an equilateral triangle, as in FIG FIG 17B shown.
- the connector 1181 which includes double electrically insulated wires, extends within the body of the carrier 1180 and provides a means for supplying electrical power to the lighting modules from within the carrier 1180.
- FIG 18A FIG. 13 shows a dodecahedron beam 1190 having twelve equal faces 1192, each of which is an equilateral pentagon, as in FIG FIG 18B shown.
- Terminal 1191 comprising double electrically insulated wires, extends within the body of carrier 1190 and provides a means for supplying electrical power to the lighting modules from within carrier 1190.
- the electrically conductive channels 1184 and 1186 may be centered on the dielectrically coated triangular surface 1182 and so are the electrically conductive channels 1194 and 1196 on the dielectrically coated pentagonal surface 1192, although the orientation of these channels in the triangular or pentagonal faces is not critical.
- the surfaces 1182 and 1192 comprise magnetic material so that a light module can be attached to each surface.
- the channels 1184 and 1186 are electrically isolated from each other and from the surface 1182 and so are the channels 1194 and 1196 from the surface 1192.
- the channels 1184 and 1186 run through the surface 1182 and are connected to the terminal 1181 so that the electrical power from Inside the body of the icosahedron carrier 1180 in the same way as in FIG 16B and the same applies to the channels 1194 and 1196 from the interior of the dodecahedron beam 1190.

- FIG 19 shows the lighting system FIG 11 with additional bumps 1206, 1208 and 1210 and a receiving groove 1212. Assuming that the bump 1210 and the groove 1212 are omitted, the bumps 1206 and 1208 ensure that the light module 1200 is correctly electrically aligned when it is on the carrier 1204 is appropriate, possibly except for the electrical polarity.
- the elevation 1210 When the elevation 1210 is positioned in the groove 1212, correct polarity is ensured, since the elevation and the groove, which are both located to the right of the center line BB in the drawing, are not centered on the carrier 1204. It should be noted that the elevation 1210 and the groove 1212 do not always have to be necessary or desired, for example in the case in which the light module 1200 is operated with alternating current.
- the light module may comprise two LEDs, each of which lights up with a different polarity, so that one LEDs would light up, regardless of the polarity of the module.
- a light module with two LEDs of opposite polarity will work with alternating current.
- Another double LED alternative is one in which each LED emits differently colored light, for example the first LED emits white light and the second, with opposite polarity, emits red light.
- the emitted red light could signal to the user that the light module is attached with the wrong polarity, or it may be a design feature of the light module that it can emit differently colored light depending on its polarity position on the carrier or depending on the polarity supplied to the light system.
- the latter case may be used in a signaling system since the color of the light emitted, e.g. B. red or green, can be changed by reversing the polarity supplied to the lighting system.
- Additional signaling options, such as blinking could be achieved by pulsing the power delivered to the lighting system.
- a single light module may consist of two groups of LEDs, with one group responding to a first applied polarity and the second group responding to the opposite applied polarity, or alternatively, a light system may use two groups of light modules, with one group of modules responding to a first Polarity reacts and the second group of modules reacts to the opposite applied polarity.
- FIG 20 shows the lighting system FIG 12 with an additional elevation 1222 on the carrier 1226 and a matching receiving groove 1224 in the light module 1228.
- the elevation 1222 is asymmetrical, having a vertical side (left side in the drawing) and a beveled side (right side in the drawing), and the same applies to the mating groove 1224.
- Attaching the module 1228 to the carrier 1226 with the bump 1222 properly positioned in the groove 1224 ensures reliable electrical contacts and correct polarity, regardless of whether the groove is relative to the center line CC is centered or not.
- protrusions, grooves and / or other means according to various aspects of the invention to ensure that the light module is attached to the carrier with reliable electrical contacts between the module and the carrier and, if appropriate, correct electrical polarity.
- a variable number of lighting modules can be electrically connected in parallel on a carrier which is connected to an external power supply or a driver circuit. Since the lighting modules can be added to or removed from the carrier at any time, the power supply must be able to regulate the operating current so that a suitable current is provided to each lighting module.
- regulated power supplies are known in the art. See for example U.S. 6,577,512 , issued June 10, 2003 to Tripathi et al., which describes a power supply for a varying number of LEDs wired in series or in parallel.
- the driver circuit may need the ability to detect the number of light modules attached to the carrier in real time.
- a resistor added in parallel with the LED on each module will facilitate the ability of the drive module to sense the number of LED light modules attached at any one time. By periodically recording the equivalent resistance of the attached LED modules, the driver circuit would regulate the operating current accordingly.
- Wulfman et al. likes the present invention in low or high voltage applications with LED, incandescent, halogen or fluorescent light sources can be used, whereas Wulfman et al. only teaches a low voltage halogen system.
- a carrier of the present invention may be adapted to carry light modules in one, two or three dimensions, whereas the housing according to Wulfman et al. are limited to a linear rail.
- An advantage of the present invention not disclosed by Wulfman et al. is taught, the feature is that the magnetic materials in the carrier and in the light module serve the dual purpose of attachment and heat dissipation in LED embodiments.
- the bracket and postures of Wulfman et al. take up significantly more space and be more conspicuous than a lighting system according to the invention, in particular in an embodiment that uses LED light sources.
- the present invention may be used in signage or signaling applications. Lighting systems according to the present invention may be used as components or assemblies in larger lighting systems. Lighting systems according to the present invention may be made with three-dimensional supports that provide an aesthetic appearance even when the lighting system is not illuminated. The present invention has a much wider variety of uses than the Wulfman et al lighting system. and provides the user with an improved ability to control the quantity, direction and properties of the emitted light.
- the present invention is therefore not restricted to the exemplary embodiments shown.
- halogen lamps can also be used.
- OLEDs can also be used as light-emitting diodes, in particular flat OLED lamps.
- the contact legs 8 can be added during manufacture or afterwards. When added later, they can be designed as an adapter piece that can at least be attached to the module and that it includes feet or can also be connected to these at a later date. The adapter pieces can thus be designed as aftermarket parts, while in a basic lamp z. B. the feet can be connected directly to the housing.

Description
Die Erfindung betrifft Leuchtsysteme aus Leuchtmittel und Träger und insbesondere Leuchtsysteme mit manuell einsetzbaren und abnehmbaren Leuchtmitteln, so dass die Quantität, Richtung und / oder die Eigenschaften des vom System emittierten Lichts leicht variiert werden können.The invention relates to lighting systems made up of lighting means and carriers and, in particular, lighting systems with manually insertable and removable lighting means, so that the quantity, direction and / or the properties of the light emitted by the system can be varied easily.
Bisher werden Leuchtmittel, insbesondere Lampen, in Leuchten mechanisch gehalten und elektrisch kontaktiert, beispielsweise mittels Klammern oder Fassungen. Dabei ist jedoch nachteilig, dass die mechanische Halterung vergleichsweise viel Bauraum benötigt und zudem eine Lösung und Neubefestigung des Leuchtmittels gerade bei einer großen Zahl von Leuchtmitteln der Leuchte aufwändig ist.So far, lighting means, in particular lamps, have been held mechanically in lights and electrically contacted, for example by means of clamps or sockets. However, it is disadvantageous here that the mechanical holder requires a comparatively large amount of installation space and, moreover, a solution and re-fastening of the illuminant is complex, especially with a large number of illuminants in the luminaire.
Insbesondere in modernen Leuchtsystemen ist es erwünscht, dass der Nutzer die Quantität, Richtung und die Eigenschaften des vom System emittierten Lichts sehr flexibel steuern kann. Bei Theaterkulissen ist man daran gewöhnt, eine Vielzahl von Lichthalterungen vorzufinden, welche Licht variierender Intensität, Farbe und anderer Eigenschaften auf die Bühne richten können. In Verkaufsumgebungen werden häufig einstellbare Reflektorlampen und Schienenleuchten verwendet, um Waren oder Auslagen zu beleuchten. In Büros und Wohnräumen werden üblicherweise Schienenleuchten verwendet, um Licht auf einen bestimmen Arbeitsbereich zu richten, oder für optische Effekte. Obwohl diese Systeme flexibel sind, besitzen sie Nachteile. Ein Nachteil besteht darin, dass sie relativ groß sind, und zwar in dem Sinne, dass die Leuchtenhalterungen auffällig sind. In vielen Anwendungen, wie etwa bei einer Vitrine für Schmuck oder anderen hochwertige Waren, ist es erwünscht, dass das Leuchtsystem so unauffällig wie möglich ist. In Anwendungen, bei denen die Erscheinung des Leuchtsystems selbst zu der ästhetischen Gesamterscheinung beiträgt, treten zusätzliche Gestaltungs- und Herstellungskosten auf. Ein weiterer Nachteil besteht darin, dass diese Systeme, obwohl sie flexibel sind, je nach Beleuchtungsanforderung mühsam einzustellen sein mögen. In vielen Fällen sind die Leuchtenhalterungen relativ schwer. Um eine Leuchtenhalterung mit einem mechanischen Stecker zu bewegen, hinzuzufügen oder zu entfernen, ist ein Werkzeug notwendig, und in einigen Fällen mag sogar eine neue elektrische Verbindung notwendig sein. Selbst in dem Fall, in dem die Leuchtenhalterung drehbar angebracht sein mag, ist der Sockel der Leuchtenhalterung typischerweise nur in einer einzigen Dimension bewegbar. Schließlich besteht noch der Nachteil, dass diese Systeme relativ teuer sind.In modern lighting systems in particular, it is desirable that the user can control the quantity, direction and properties of the light emitted by the system very flexibly. With theater backdrops, one is used to finding a multitude of light fixtures that can direct light of varying intensity, color and other properties onto the stage. Adjustable reflector lamps and track lights are often used in retail environments to illuminate goods or displays. Track lights are commonly used in offices and living spaces to direct light onto a specific work area or for optical effects. Although these systems are flexible, they have disadvantages. One disadvantage is that they are relatively large, in the sense that the lamp brackets are noticeable. In many applications, such as a showcase for jewelry or other high-quality goods, it is desirable that the lighting system is as inconspicuous as possible. In applications in which the appearance of the lighting system itself contributes to the overall aesthetic appearance, additional Design and manufacturing costs. Another disadvantage is that these systems, while flexible, may be cumbersome to adjust based on lighting requirements. In many cases, the lamp holders are relatively heavy. A tool is required to move, add, or remove a lamp holder with a mechanical connector, and in some cases even a new electrical connection may be required. Even in the event that the lamp holder may be rotatably attached, the base of the lamp holder can typically only be moved in one single dimension. Finally, there is the disadvantage that these systems are relatively expensive.
Es ist eine Aufgabe der Erfindung, die Defizite des Stands der Technik zu vermeiden.It is an object of the invention to avoid the deficiencies of the prior art.
Eine weitere Aufgabe der vorliegenden Erfindung ist es, eine Möglichkeit zur einfachen und platzsparenden Montage von Leuchtmitteln bereitzustellen.Another object of the present invention is to provide a possibility for simple and space-saving assembly of lighting means.

Noch eine weitere Aufgabe der Erfindung ist es, ein Leuchtsystem bereitzustellen, das Glüh-, Halogen-, LED- und Leuchtstoff-Lichtquellen verwenden kann.Yet another object of the invention is to provide a lighting system that can use incandescent, halogen, LED, and fluorescent light sources.
Eine weitere Aufgabe der Erfindung ist es, ein Leuchtsystem bereitzustellen, das in der Lage ist, in einer Vielzahl von dreidimensionalen räumlichen Gebilden, z. B. Parallelepipeden, Kugeln, Polyedern, hergestellt zu werden.Another object of the invention is to provide a lighting system that is able to display in a variety of three-dimensional spatial structures, e.g. B. parallelepipedes, spheres, polyhedra to be produced.

Das Leuchtsystem weist mindestens ein Leuchtmittel, das ein oder mehrere Einzellichtquellen und zwei magnetisch haftende elektrische Anschlüsse entgegengesetzter magnetischer Polung aufweist, und mindestens einen ebenen Träger, aufweisend mehrere Paare von Kontakten, von denen jedes Paar einen zu einer ersten Gruppe von Kontakten gehörigen Kontakt und einen zu einer zweiten Gruppe von Kontakten gehörigen Kontakt aufweist, zwischen denen ein elektrisches Potenzial anlegbar ist, auf, wobei
- die Kontakte der ersten Gruppe und die Kontakte der zweiten Gruppe eine entgegengesetzte magnetische Polung aufweisen und nebeneinander auf dem Träger angeordnet sind,
- jeder der Kontakte als eine magnetische Aufsatzfläche zum Aufsatz eines Anschlusses eines Leuchtmittels mit dazu umgekehrter magnetischer Polarität ausgestaltet ist und wobei
- der Träger mindestens zwei Sätze von Paaren, die für unterschiedliche Arten von Leuchtmitteln vorgesehen sind, mit zwischen den Sätzen unterschiedlich geformten Kontakte aufweist,

- each of the contacts is designed as a magnetic attachment surface for attachment of a connection of a lighting means with reversed magnetic polarity and wherein
- the carrier has at least two sets of pairs intended for different types of light sources with differently shaped contacts between the sets,
- a lateral spacing of contacts of a respective pair of contacts of a common set of pairs is less than a spacing of these contacts to similarly shaped contacts of another set of pairs and
- each set can be controlled independently.
Durch die unterschiedliche Form der Kontakte zumindest zwischen zwei Paaren, kann vorteilhafterweise optisch einfach zwischen Kontaktpaaren mit unterschiedlichen Eigenschaften oder für unterschiedliche Leuchtmittel unterschieden werden.Due to the different shape of the contacts, at least between two pairs, it is advantageously possible to distinguish between contact pairs with different properties or for different lighting means.
Durch die jeweils umgekehrte magnetische Polarität der Anschlüsse des Leuchtmittels und der Kontakte des Trägers kann ein Falschanschluss vermieden werden. Es kann daher zwischen den beiden Anschlüssen magnetisch diskriminiert werden; und es wird diesen eine inhärente Möglichkeit zur Vermeidung von Fehlanschlüssen bereitgestellt.Incorrect connection can be avoided due to the reversed magnetic polarity of the connections of the illuminant and the contacts of the carrier. It can therefore be magnetically discriminated between the two connections; and they are provided with an inherent way to avoid misconnections.
Durch die Sätze von unterschiedlich geformten Kontakte des Trägers können unterschiedliche Arten von Leuchtmitteln auf einfache Weise flexibel angesteuert werden.The sets of differently shaped contacts of the carrier allow different types of lighting means to be controlled in a simple and flexible manner.
Durch die magnetisch haftenden elektrischen Anschlüsse kann das Leuchtmittel, z. B. eine Lampe, einfach und platzsparend an einem entsprechenden magnetischen oder magnetisierbaren elektrischen Kontakt lösbar befestigt werden.Due to the magnetically adhesive electrical connections, the light source, e.g. B. a lamp, easily and space-savingly attached to a corresponding magnetic or magnetizable electrical contact.

B. als starre oder flexible quadratische Platte mit den Maßen 40 cm x 40 cm.The carrier can in particular be designed as a base plate with a lateral dimension of no more than 1 m, e.g. B. as a rigid or flexible square plate with the
In einer Ausgestaltung ist zwischen mindestens zwei Gruppen bzw. den diesen zugehörigen Kontakten eine Gleichspannung anlegbar.In one embodiment, a DC voltage can be applied between at least two groups or the contacts associated with them.
In einer alternativen Ausgestaltung ist zwischen mindestens zwei Gruppen bzw. den diesen zugehörigen Kontakten eine Wechselspannung anlegbar.In an alternative embodiment, an alternating voltage can be applied between at least two groups or the contacts associated with them.
In einer weiteren Ausgestaltung sind die elektrischen Kontakte in zwei Gruppen gruppiert sind und in einem Schachbrettmuster mit einer abwechselnden Anordnung der Kontakte der beiden Gruppen angeordnet.In a further embodiment, the electrical contacts are grouped in two groups and arranged in a checkerboard pattern with an alternating arrangement of the contacts of the two groups.

In noch einer weiteren, alternativen oder zusätzlichen, Ausgestaltung sind die elektrischen Kontakte in zwei Gruppen gruppiert und in einem Gittermuster angeordnet, bei dem das Gitter einen Kontakt der ersten Gruppe und die vom Gitter eingeschlossenen Flächen Kontakte der zweiten Gruppe darstellen.In yet another, alternative or additional embodiment, the electrical contacts are grouped in two groups and arranged in a grid pattern, in which the grid represents a contact of the first group and the surfaces enclosed by the grid represent contacts of the second group.
Die Paare sind vorzugsweise in einem regelmäßigen Muster auf dem Träger verteilt.The pairs are preferably distributed in a regular pattern on the carrier.
Das zwischen den Kontakten unterschiedlicher Paare anlegbare elektrisches Potenzial ist nicht notwendigerweise gleich.The electrical potential that can be applied between the contacts of different pairs is not necessarily the same.
Der Träger kann insbesondere mindestens drei Sätze bzw. Arten von jeweils ein oder mehreren Paaren mit zwischen den Sätzen unterschiedlich geformten Kontakten aufweisen. Dadurch können insbesondere Kontaktpaare für LED-Lampen mit unterschiedlicher Grundfarbe, z. B. R, G und B, bereitgestellt werden, wobei die Sätze insbesondere unabhängig ansteuerbar sind. Auch sind weitere Sätze für weitere Farben, wie weiß oder bernsteinfarben, realisierbar, oder für andere Leuchtmittel, wie Halogenlampen.The carrier can in particular have at least three sets or types of one or more pairs each with differently shaped contacts between the sets. As a result, contact pairs for LED lamps with different basic colors, e.g. B. R, G and B, are provided, wherein the sentences are in particular independently controllable. Further sets for other colors, such as white or amber, can also be implemented, or for other light sources such as halogen lamps.
Allgemein kann ein Träger diese oder andere Kontaktmuster aufweisen, und zwar ein bestimmtes Kontaktmuster oder beispielsweise auch mehrere Kontaktmuster nebeneinander.In general, a carrier can have these or other contact patterns, specifically a specific contact pattern or, for example, several contact patterns next to one another.
Der Träger kann eine flexible oder starre Grundplatte aufweisen.The carrier can have a flexible or rigid base plate.
Die magnetische Polung kann also mit einer Gruppenzugehörigkeit korrelieren, insbesondere mit einer Verbindung zu einem Speisungsanschluss. Die Kontakte können dauermagnetisch oder temporär magnetisierbar sein, z. B. mittels eines Elektromagneten.The magnetic polarity can thus correlate with a group membership, in particular with a connection to a supply connection. The contacts can be permanently or temporarily magnetizable, e.g. B. by means of an electromagnet.
Der Träger ist vorzugsweise in zumindest eine Richtung erweiterbar, insbesondere durch Verbinden mit einem weiteren, insbesondere gleichartigen, Träger. Die verbundenen Träger benötigen vorzugsweise nur eine gemeinsame Stromversorgung und / oder Ansteuerung. Dazu kann der Träger mit einem Verbindungsmittel, insbesondere Rast- oder Steckmittel, ausgerüstet sein, das eine mechanische und elektrische Verbindung mit einem passenden Gegenverbindungsmittel eines anderen Trägers ermöglicht. Der Träger weist vorzugsweise an einer Seite ein Verbindungsmittel und an einer gegenüberliegenden Seite ein Gegenverbindungsmittel auf.The carrier is preferably expandable in at least one direction, in particular by connecting it to a further, in particular similar, carrier. The connected carriers preferably only require a common power supply and / or control. For this purpose, the carrier can be equipped with a connecting means, in particular a latching or plug-in means, which provides a mechanical and electrical connection with a suitable counter-connecting means of another carrier enables.

Insbesondere können unterschiedliche Sätze von Kontakten des Trägers für mit unterschiedlicher Farbe leuchtende Leuchtmittel vorgesehen sein.In particular, different sets of contacts of the carrier can be provided for illuminants with different colors.
Das Leuchtsystem kann ferner so ausgestaltet sein, dass die Kontakte des Trägers eines Satzes und die Anschlüsse eines dafür vorgesehenen Leuchtmittels so geformt sind, dass eine Kontaktierung von nicht füreinander vorgesehenen Anschlüssen und Kontakten verhindert wird.The lighting system can also be designed in such a way that the contacts of the carrier of a set and the connections of a lighting means provided for this purpose are shaped in such a way that contacting of connections and contacts that are not intended for one another is prevented.

Das LED-Leuchtmittel 2 weist eine weiß leuchtende LED 4 als Lichtquelle auf, die an einem Gehäuse 5 montiert ist und zur Strahlführung seitlich von einem Reflektor 6 umgeben ist. Zur Stromversorgung der LED 4 und einer im Gehäuse 5 vorhandenen Ansteuerschaltung 7 für die LED 4 führen aus dem Gehäuse 5 mechanisch flexible Kontaktbeine 8 heraus, die jeweils einen permanentmagnetischen Fuß 9 aufweisen. Die Füße 9 dienen somit sowohl der elektrischen Kontaktierung des LED-Leuchtmittels 2 als auch dessen lösbarer Befestigung. Die Einheit umfassend das Gehäuse 5 (mit Ansteuerung 7), die LED 4 und den Reflektor 6 kann auch als LED-Modul 2a bezeichnet werden.The
Der ebene Träger 3 weist in ein Trägermaterial 10 eingebettete elektrische Kontakte 11,12 auf, deren Oberfläche 13 freiliegt und somit als elektrische Kontaktfläche und als Aufsatzfläche für die Füße 9 dient. Die gezeigten Kontakte 11,12 weisen ein unterschiedliches elektrisches Potential auf, so dass über sie von dem Leuchtmittel 2 eine elektrische Leistung zum Betrieb der LED 4 abgegriffen wird.The
Die Kontakte 13 sind in ihrer Funktion als Aufsatzfläche 13 so gestaltet, dass die magnetischen Füße 9 flächig an ihnen haften können. Dazu weisen die Kontakte 11,12 vorzugsweise ein permanentmagnetisches Material auf; welches an der Kontaktfläche 13 eine magnetische Polung aufweist, die einer magnetischen Polung des zugehörigen Fußes 9 entgegengesetzt ist. Die Kontakte 11,12 sind zur Ausrichtung des LED-Leuchtmittels 2 zueinander bezüglich ihrer Kontaktfläche 13 entgegensetzt magnetisch gepolt. So kann bei Gleichstromversorgung der Kontakte 11,12 ein positives elektrisches Potential des linken Kontakts 11 mit einer positiven magnetischen Polung an dessen Oberfläche 13 verbunden sein und ein geringeres elektrisches Potential des rechten Kontakts 12 (z. B. Masse) mit einer negativen magnetischen Polung an dessen Oberfläche 13 verbunden sein. Entsprechend weist ein Fuß 9, der an ein positives elektrisches Potential anzuschließen ist, eine an seiner Kontaktfläche negative magnetische Polung auf; und ein Fuß 9, der an ein niedrigeres elektrisches Potential anzuschließen ist, weist eine an seiner Kontaktfläche positive magnetische Polung auf. Dadurch kann insbesondere bei Gleichstrombetrieb des LED-Leuchtmittels 6 eine korrekte elektrische Polung sichergestellt werden, da sich bei falscher Orientierung des LED-Leuchtmittels 2 sich dessen Füße 9 und die Kontakte 11,12 gegenseitig abstoßen und sich nur bei richtiger Orientierung anziehen. Die magnetische Polung ist mit den Symbolen '+' bzw. '-' eingezeichnet. Alternativ weisen die Kontakte des Trägers 3 oder die Füße 9 ein ferromagnetisches Material auf, insbesondere ein Eisenmaterial wie Stahl.The
Dadurch kann das LED-Leuchtmittel 2 besonders einfach und platzsparend kontaktiert werden.As a result, the LED
Der Reflektor 6 kann zum Schutz der Leuchtdiode 4 mittels einer transparenten Abdeckung 14 abgedeckt sein.The
Die Ansteuerschaltung 7 kann insbesondere im Wechselstrombetrieb der Kontakte 11,12 als Treiber für die Leuchtdiode 4 ausgelegt sein. Die Ansteuerschaltung 7 kann ferner verschiedene weitere Funktionen aufweisen, beispielsweise eine Dimmfunktion, bei deren Aktivierung die Leuchtstärke der LED 4 gezielt verringert wird. Eine weitere mögliche Funktion ist Verwendung farbvariabler Leuchtmittel eine Änderung der Leuchtfarbe des Leuchtmittels, z. B. bei Verwendung eines LED-Farbclusters aus verschiedenfarbigen, einzeln ansteuerbaren LEDs.The
Die Ansteuerschaltung 7 weist zur Aktivierung der verschiedenen Funktionen ein Empfangsmittel 15 mit einer eine Funkantenne zum Empfang von drahtlos übertragenen Funk-Steuersignalen auf. Das Empfangsmittel 15 ist mit der Ansteuerschaltung 7 kommunikativ gekoppelt, so dass die Ansteuerschaltung 7 die Steuersignale umsetzen kann.To activate the various functions, the
Die Ansteuerung 7 ist ferner selektiv adressierbar, d. h., dass sie Befehle umsetzt, die einen passenden Identcode aufweisen, und Befehle nicht umsetzt, die keinen passenden Identcode aufweisen. Dadurch können LED-Leuchtmittel 2 oder Gruppen von LED-Leuchtmitteln 2 mit gleichem Identcode gezielt angesteuert werden. So können insbesondere Gruppen gleichfarbiger Leuchtdioden bzw. Leuchtmittel selektiv angesteuert werden, um beispielsweise den Farbeindruck des Systems zu ändern, z. B. durch Einschalten und / oder Ausschalten von Leuchtmitteln bestimmter Farbe.The
Mit dem Träger 3 kann eine - hier nicht dargestellte - Ansteuerschaltung zur Ansteuerung der mit dem Träger 3 verbundenen Leuchtmittel 2 verbunden sein. So kann über diese Ansteuerschaltung alternativ oder zusätzlich eine Dimmfunktion bereitgestellt werden, welche alle Kontakte oder eine ausgewählte Teilmenge von Kontakten geringer bestromt. Ein Vorsehen einer Dimmfunktion am Träger statt an den Leuchtmitteln weist den Vorteil auf, dass ein Dimmen mittels nur einer Ansteuerschaltung realisierbar ist und somit besonders kostengünstig. Tendenziell ist es zur Aufwandsverringerung vorteilhaft, möglichst viele Funktionen über eine Ansteuerschaltung des Trägers 3 zu realisieren anstatt über Ansteuerschaltungen 7 der Leuchtmittel. Die Ansteuerungen 7 können selektiv arbeiten, indem nur Steuersignale umgesetzt werden, welche für das bestimmte Leuchtmittel vorgesehen sind. So mag eine der gezeigten Leuchtmittel 2 auf ein mit einem bestimmten Identitätscode versehenes Datensignal hin die Leuchtstärke herunterdimmen, während ein anderes der Leuchtmittel 2 auf den Dimmbefehl nicht reagiert. Die Steuersignale können z. B. durch eine Modulation des Trägersignals übertragen werden. Die Ansteuerung weist dann bevorzugt eine entsprechende Datenauslesefunktion auf, z. B. einen Decoder.A control circuit (not shown here) for controlling the lighting means 2 connected to the
Alternativ können die Kontakte 11,12 auch anders verschaltet sein. Auch kann eine andere Art von Stromversorgung verwendet werden, z. B. eine Wechselspannungsquelle. Allgemein kann der Träger mit einer geeigneten Stromversorgungseinheit ausgerüstet sein, z. B. mit einem Transformator zur Umwandlung von Netzspannung in eine Versorgungsspannung, gegebenenfalls unter Verwendung eines Gleichrichters.Alternatively, the
Ein so verkapseltes Leuchtmittel 2 weist den Vorteil auf, dass es auch als Schüttgut auf einem Träger aufbringbar ist, insbesondere, falls das Leuchtmittel eine geringe Ausdehnung aufweist. Denn durch die runde Grundform kann das Leuchtmittel 2 so lange auf dem Träger rollen, bis es auf der ebenen Unterseite aufsitzt und dann durch die magnetische Haftkraft am Träger gehalten wird. Dies ist insbesondere vorteilhaft, wenn die magnetische Polung der Kontaktflächen 18 der Füße unterschiedlich ist und mit einer zugehörigen magnetischen Polung zugehöriger Kontakte des Trägers korreliert, wie beispielsweise oben beschrieben. Denn dann wird sichergestellt, dass die Füße 9 nur auf geeigneten Kontakten des Trägers aufsetzen, z. B. verbunden mit unterschiedlichen Anschlüssen der (Gleich- oder Wechsel-) Spannungsquelle.A
Alternativ ist die Form der Verkapselung nicht eingeschränkt und kann beispielsweise quaderförmig, scheibenförmig oder zylindrisch sein, was sich insbesondere durch ein entsprechendes Vergießen erreichen lässt. Eine Verkapselung kann auch durch Verwendung von Kapselschalen erreichen werden, deren Zusammensetzen aber vergleichsweise aufwändig ist.Alternatively, the shape of the encapsulation is not restricted and can, for example, be cuboid, disk-shaped or cylindrical, which can be achieved in particular by appropriate encapsulation. Encapsulation can also can be achieved by using capsule shells, but their assembly is comparatively complex.
Das LED-Leuchtmittel 2 zeigt die Kontaktbeinchen 8 im gebogenen Zustand, bei dem die Abstrahlrichtung des Leuchtmittels 2 durch die Biegung individuell ausgerichtet worden ist. Alternativ zu den zwei Kontaktbeinchen 8 kann beispielsweise ein Schwanenhals mit einem biegsamen dünnen Rohr verwendet werden, das die elektrischen Zuleitungen trägt bzw. aufnimmt.The
Zur Beschreibung der nun folgenden Figuren gelten die folgenden Definitionen. Ein "abnehmbares Leuchtmodul" meint ein Leuchtmodul, das manuell an dem Träger angebracht, davon abgenommen oder neu daran positioniert werden mag, und zwar ohne die Verwendung von Werkzeugen oder die Notwendigkeit von dauerhaften, per Hand verlegten elektrische Verbindungen, wie etwa einer Verbindung, die durch eine Schraube, einen Spleiß, einen Schraub-Drahtverbinder usw. hergestellt wird. Der Ausdruck "magnetisches Material" meint ein Material, das entweder ein Permanentmagnet ist oder ein Material, das von einem Permanentmagneten stark angezogen wird.

Nun sollte insbesondere unter besonderem Bezug auf die folgenden Zeichnungen beachtet werden, dass die in den Zeichnungen gezeigte Orientierung der Erfindung und des emittierten Lichts nur von beispielhaftem und nicht von begrenzendem Charakter sind. In vielen Anwendungen wird das Licht im Wesentlichen nach unten emittiert.
Das Leuchtmodul 1014 weist eine am Sockel 1030 angebrachte Lichtquelle 1028 auf. Die Lichtquelle 1028 weist Zuleitungsdrähte 1036 und 1038 auf, die mit elektrisch leitfähigen Pfaden 1032 und 1034 verbunden sind, welche einen physikalischen und elektrischen Kontakt mit den Kanälen 1020 bzw. 1018 des Trägers 1012 herstellen. Unter verschiedenen Gesichtspunkten der Erfindung wird die Lichtquelle 1028 auswechselbar am Sockel angebracht sein, so dass die Lichtquelle, z. B. eine Glühbirne, nach ihrer Brenndauer ersetzt werden mag. Wie oben besprochen, mag eine dielektrische Beschichtung 1031 (in
Eine flexible Schaltung bzw. Flexschaltung, die Kanäle 1018 und 1020 umfasst, mag als Träger 1012 dienen. Die flexible Schaltung mit druckempfindlichem, thermisch leitfähigem Haftmittel mag auf jegliches magnetische Substratmaterial ohne dielektrische Behandlung aufgebracht werden. Die dielektrische Stärke wird durch das flexible Schaltungsmaterial bereitgestellt. Diese Art von Träger ist insbesondere für eine Anbringung unter einer Ablage oder einem Schrank aus Metallblech oder Ähnlichem oder an einem flexiblen magnetischen Streifen gut geeignet.A flexible circuit or flex

Die optimale Spannung zum Betreiben einer Schaltung mit einer Vielzahl von LED-Lichtquellen wird von der Anzahl von Lichtquellen, ihren Eigenschaften und Anordnung in der Schaltung und von anderen Schaltungskomponenten abhängen. Der Strom mag abhängig von der Anwendung Gleichstrom oder Wechselstrom sein. Bei einer LED-Lichtquelle beträgt die elektrische Leistung, die über die Anschlüsse 1022 und 1024 der
Jedoch liegen andere Arten von Lichtquellen, wie etwa Glüh-, Wolfram/Halogen- und Leuchtstofflampen, im Umfang der Erfindung. Ein Abspanntransformator mag verwendet werden, um die über die Anschlüsse 1022 und 1024 angelegte Spannung zu verringern, falls nötig, wie etwa bei einer herkömmlichen Wolfram/Halogen-Schienenleuchte. Bei Hochspannungsausführungsformen mag das Leuchtsystem in einem Gehäuse mit einer lichtdurchlässigen Abdeckung angebracht sein, welche einen Zugang zu den freigelegten Kanälen 1018 und 1020 verhindert, und zwar vorzugsweise mit einem Notausschalter, der die Leistung über die Kanäle 1018 und 1020 automatisch abschaltet, wenn die Abdeckung offen ist.However, other types of light sources, such as incandescent, tungsten / halogen and fluorescent lamps, are within the scope of the invention. A step-down transformer may be used to reduce the voltage applied across
Insbesondere bei LED-Ausführungsformen sind der Sockel 1030 und der Träger 1026 so bemessen, dass sie als eine Wärmesenke wirken, die genügend Wärme vom Leuchtmodul 1028 ableitet, um die thermischen Betriebsbedingungen des Moduls zu erfüllen. Insbesondere dient der Magnet als ein thermischer Pfad zur Wärmeübertragung zum Substratteil des Trägers. Das Substrat ist die effektive Wärmesenke.In the case of LED embodiments in particular, the
Eine breite Vielfalt an LEDs in allen Farben, die erfindungsgemäß zur Verwendung geeignet sind, ist über Osram Opto Semiconductors Inc., 2650 San Tomas Expressway, Suite 200, Santa Clara, CA 95051, erhältlich. LEDs der DRAGON-Familie sind besonders gut geeignet.A wide variety of LEDs in all colors that are suitable for use in accordance with the invention is available from Osram Opto Semiconductors Inc., 2650 San Tomas Expressway, Suite 200, Santa Clara, CA 95051. LEDs of the DRAGON family are particularly well suited.

Der Träger 1100 mag eine Vielfalt an Ausführungsformen und Anwendungen aufweisen. In einer wie in
Zurück zu
Ein Träger braucht nicht rechteckig zu sein.
Gesichtspunkte der Offenbarung sind auch auf drei Dimensionen anwendbar.
Um die Leuchtmodule am kugelförmigen Träger 1140 anzubringen, muss die Trägeroberfläche im Wesentlichen flach sein. Der hierin verwendete Ausdruck "im Wesentlichen flach" bedeutet, dass die Trägeroberfläche entweder flach ist oder einen ausreichend großen Krümmungsradius aufweist, um es den Leuchtmodulen zu ermöglichen, an der Trägeroberfläche mittels magnetischer Anziehung ohne Gleiten oder Kippen angebracht zu werden. Der Abstand zwischen den Kanälen jedes Kanalpaares sollte klein genug sein, dass ein zuverlässiger elektrischer und thermischer Kontakt zwischen den Kanälen und den entsprechenden Pfaden eines angebrachten Leuchtmoduls stattfindet. Um einen zuverlässigen elektrischen und thermischen Kontakt zwischen den Trägerkanälen und den entsprechenden Pfaden eines angebrachten Leuchtmoduls zu erleichtern, mag die Oberfläche des Leuchtmoduls gekrümmt sein, um sich an die Krümmung des Trägers anzupassen. Der Ausdruck "im Wesentlichen flach", wie hierin bezüglich einer Moduloberfläche verwendet, bedeutet, dass die Moduloberfläche entweder flach oder gekrümmt sein mag, so dass das Modul mittels magnetischer Anziehung ohne Gleiten oder Kippen an der Trägeroberfläche angebracht werden kann, obwohl die Krümmungen der Träger- und Moduloberflächen nicht identisch sein müssen. Ferner mögen die Trägerkanäle bezüglich der Oberfläche des Trägers erhöht sein, wie in
Obwohl
Unter weiteren Gesichtspunkten der Erfindung zeigen die
Wie in den vorangegangenen Beispielen beschrieben, sind zahlreiche Ausführungsformen und Varianten der Trägerstruktur möglich und praktikabel. In allen diesen Ausführungsformen ist es wichtig, dass die elektrischen Pfade des Leuchtmoduls richtig an den elektrischen Kanälen des Trägers positioniert sind, so dass das Leuchtmodul zuverlässig gespeist werden kann. Darstellungen oder Graphiken mögen verwendet werden, um eine Anleitung für die richtige Ausrichtung von Modulen am Träger bereitzustellen.
In einer Gleichstromausführungsform, bei der die Lichtquelle 1214 eine LED ist und die Erhebung 1210 und die Nut 1212 weggelassen worden sind, würde einem Nutzer auffallen, dass das Leuchtmodul mit falscher Polarität angebracht worden ist, und zwar aufgrund der Tatsache, dass die LED, als sie angeschaltet wurde, nicht geleuchtet hat, woraufhin der Nutzer das Leuchtmodul erneut mit der umgedrehten Polarität anbringen würde. Alternativ mag das Leuchtmodul zwei LEDs umfassen, von denen jedes mit verschiedener Polarität leuchtet, so dass eine LED leuchten würden, egal welche Polarität das Modul aufweist. Ein Leuchtmodul mit zwei LEDs entgegengesetzter Polarität wird mit Wechselstrom funktionieren. Eine weitere Doppel-LED-Alternative ist eine, bei der jede LED unterschiedlich gefärbtes Licht emittiert, beispielsweise emittiert die erste LED weißes Licht und die zweite, mit entgegengesetzter Polarität, emittiert rotes Licht. Das emittierte rote Licht könnte dem Nutzer signalisieren, dass das Leuchtmodul mit der falschen Polarität angebracht ist, oder es mag ein Ausgestaltungsmerkmal des Leuchtmoduls sein, dass es abhängig von seiner Polaritätsposition am Träger oder abhängig von der zum Leuchtsystem gelieferten Polarität unterschiedlich gefärbtes Licht emittieren kann. Der letztere Fall mag in einem Signalisierungssystem verwendet werden, da die Farbe des emittierten Lichts, z. B. rot oder grün, mittels Umkehrens der zum Leuchtsystem gelieferten Polarität geändert werden kann. Zusätzliche Signalisierungsoptionen, wie etwa Blinken, könnten mittels Pulsens der zum Leuchtsystem gelieferten Leistung erreicht werden. Ein einzelnes Leuchtmodul mag aus zwei Gruppen von LEDs bestehen, wobei eine Gruppe auf eine erste angelegte Polarität reagiert und die zweite Gruppe auf die entgegengesetzte angelegte Polarität reagiert, oder alternativ mag ein Leuchtsystem zwei Gruppen von Leuchtmodulen verwenden, wobei eine Gruppe von Modulen auf eine erste Polarität reagiert und die zweite Gruppe von Modulen auf die entgegengesetzte angelegte Polarität reagiert.In a DC embodiment in which the
In jeder der vorangegangenen Ausführungsformen der Erfindung kann eine variable Anzahl von Leuchtmodulen an einem Träger, der mit einer externen Leistungsversorgung oder einer Treiberschaltung verbunden ist, elektrisch parallel verbunden sein. Da die Leuchtmodule jederzeit zum Träger hinzugefügt oder davon entfernt werden können, muss die Leistungsversorgung in der Lage sein, den Betriebsstrom so zu regulieren, dass jedem Leuchtmodul ein geeigneter Strom bereitgestellt wird. Solche regulierten Leistungsversorgungen sind aus dem Stand der Technik bekannt. Siehe beispielsweise
In einer Ausführungsform, die eine variable Anzahl von parallel geschalteten LED-Leuchtmodulen verwendet, mag die Treiberschaltung die Fähigkeit benötigen, die Anzahl von am Träger angebrachten Leuchtmodulen in Echtzeit zu erfassen. Ein Widerstand, der parallel zu der LED an jedem Modul hinzugefügt ist, wird die Fähigkeit des Antriebsmoduls, die Anzahl von angebrachten LED-Leuchtmodulen jederzeit zu erfassen, erleichtern. Mittels periodischen Erfassens des äquivalenten Widerstands der angebrachten LED-Module würde die Treiberschaltung den Betriebsstrom entsprechend regulieren.In an embodiment that uses a variable number of LED light modules connected in parallel, the driver circuit may need the ability to detect the number of light modules attached to the carrier in real time. A resistor added in parallel with the LED on each module will facilitate the ability of the drive module to sense the number of LED light modules attached at any one time. By periodically recording the equivalent resistance of the attached LED modules, the driver circuit would regulate the operating current accordingly.
Wieder bezüglich des oben genannten Patents an Wulfman et al. mag die vorliegende Erfindung in Nieder- oder Hochspannungsanwendungen mit LED-, Glüh-, Halogen- oder Leuchtstoffleuchtquellen verwendet werden, wohingegen Wulfman et al. nur ein Niederspannungs-Halogen-System lehrt. Ein Träger der vorliegenden Erfindung mag daran angepasst sein, Leuchtmodule in einer, zwei oder drei Dimensionen zu tragen, wohingegen die Gehäuse nach Wulfman et al. auf eine lineare Schiene beschränkt sind. Ein Vorteil der vorliegenden Erfindung, der nicht von Wulfman et al. gelehrt wird, ist das Merkmal, dass die magnetischen Materialien im Träger und im Leuchtmodul dem zweifachen Zweck des Anbringens und der Wärmeabführung in LED-Ausführungsformen dienen. Bei Anwendungen, bei denen es erwünscht ist, dass das Leuchtsystem so unauffällig wie möglich ist, wie etwa einem System unter einem Ladentisch zum Beleuchten von Ware, werden die Klammer und die Haltungen von Wulfman et al. bedeutend mehr Platz einnehmen und auffälliger sein als ein erfindungsgemäßes Leuchtsystem, insbesondere in einer Ausführungsform, die LED-Lichtquellen verwendet. Es gibt weitere Vorteile. Die vorliegende Erfindung mag in Beschilderungs- oder Signalisierungsanwendungen verwendet werden. Leuchtsysteme gemäß der vorliegenden Erfindung mögen als Komponenten oder Baueinheiten in größeren Leuchtsystemen verwendet werden. Leuchtsysteme gemäß der vorliegenden Erfindung mögen mit dreidimensionalen Trägern hergestellt werden, die selbst dann ein ästhetisches Erscheinungsbild bereitstellen, wenn das Leuchtsystem nicht erleuchtet ist. Die vorliegende Erfindung weist eine viel breitere Vielfalt von Anwendungen auf als das Leuchtsystem von Wulfman et al. und stellt dem Nutzer eine verbesserte Möglichkeit zur Steuerung der Quantität, Richtung und der Eigenschaften des emittierten Lichts bereit.Referring again to the aforementioned Wulfman et al. likes the present invention in low or high voltage applications with LED, incandescent, halogen or fluorescent light sources can be used, whereas Wulfman et al. only teaches a low voltage halogen system. A carrier of the present invention may be adapted to carry light modules in one, two or three dimensions, whereas the housing according to Wulfman et al. are limited to a linear rail. An advantage of the present invention not disclosed by Wulfman et al. is taught, the feature is that the magnetic materials in the carrier and in the light module serve the dual purpose of attachment and heat dissipation in LED embodiments. In applications where it is desired that the lighting system be as inconspicuous as possible, such as an under-counter system for lighting merchandise, the bracket and postures of Wulfman et al. take up significantly more space and be more conspicuous than a lighting system according to the invention, in particular in an embodiment that uses LED light sources. There are other advantages. The present invention may be used in signage or signaling applications. Lighting systems according to the present invention may be used as components or assemblies in larger lighting systems. Lighting systems according to the present invention may be made with three-dimensional supports that provide an aesthetic appearance even when the lighting system is not illuminated. The present invention has a much wider variety of uses than the Wulfman et al lighting system. and provides the user with an improved ability to control the quantity, direction and properties of the emitted light.
Während gezeigt worden ist, was zur Zeit als die bevorzugten Ausführungsformen der Erfindung angesehen wird, wird es dem Fachmann klar sein, dass vielfältige Änderungen und Modifikationen darin vorgenommen werden können, ohne vom Umfang der Erfindung, wie er in den beiliegenden Ansprüchen definiert ist, abzuweichen. Dementsprechend sollte beachtet werden, dass die Erfindung nur beispielhaft und nicht begrenzend beschrieben worden ist.While there has been shown what are presently considered to be the preferred embodiments of the invention, it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the scope of the invention as defined in the appended claims . Accordingly, it should be noted that the invention has been described only by way of example and not limiting.
Somit ist die vorliegende Erfindung nicht auf die gezeigten Ausführungsbeispiele beschränkt. So können alternativ oder zusätzlich zu Leuchtdioden auch Halogenlampen eingesetzt werden. Als Leuchtdioden kommen auch OLEDs in Frage, insbesondere flächige OLED-Leuchtmittel. So können die Kontaktbeine 8 bei Herstellung oder nachträglich hinzugefügt werden. Bei nachträglicher Hinzufügung können sie als Adapterstück ausgeprägt sein, das zumindest an das Modul anbringbar ist und sie Füße umfasst oder auch mit diesen nachträglich zu verbinden ist. Die Adapterstücke können somit als Nachkaufteile ausgelegt sein, während bei einer Grundlampe z. B. die Füße direkt mit dem Gehäuse verbindbar sind.The present invention is therefore not restricted to the exemplary embodiments shown. As an alternative or in addition to light-emitting diodes, halogen lamps can also be used. OLEDs can also be used as light-emitting diodes, in particular flat OLED lamps. So the
