Description

lighting system

The invention relates to a lighting system. A lighting system can be a light module, which a

PCB and at least one on the PCB

arranged illuminant having. Furthermore, the lighting system may have an electrical component, which the lighting module and in particular the one or more

Illuminant of the light module activates to these

operate. The electrical component may be formed, for example, as a ballast.

Usually, it is provided that the ballast is arranged separately from the lighting module, for example by the electrical component arranged on another, separated from the printed circuit board of the lighting module

PCB is attached. The printed circuit board of the lighting module and the printed circuit board of the electrical component can then be attached, for example, to a holder which

Elements, such as wires, has, via which an electrical connection between the two circuit boards and thus between the lamps and the electrical component can be made. This leads to a complex assembly, since first the bulbs must be mounted on the first circuit board and the electrical component on the second circuit board before an electrical connection, for example by forming a wiring, between the two circuit boards and thus between the electrical component and the Bulbs can be produced. It must have a sufficient mechanical and thermal connection through the

Fixing elements, such as a holder, and be ensured by the elements for forming the electrical connection. Furthermore, safety requirements, such as the provision of sufficiently dimensioned creepage distances and clearances, must be selected by selecting specific materials as well the use of an additional housing and / or

Spacers are respected.

Various embodiments provide a lighting system, which is characterized by a simplified installation in compliance with safety requirements.

In various embodiments, a lighting system on iron: at least one light module, which a

PCB and at least one on the PCB

arranged illuminant, and at least one electrical component for operating the illuminant of the light module, wherein the electrical component is electrically connected to the light module and wherein the electrical

Component is attached directly to the light module.

Advantageous embodiments and expedient developments of the invention are specified in the dependent claims. Such a lighting system is characterized in that the electrical component is now directly on the

Luminous module is attached and is thus arranged directly adjacent to the light module. Immediately means here that between the light module and the electrical component, no gap or space is formed, but the

Luminous module is applied directly to an outer surface of the electrical component and attached thereto. The outer surface of the electrical component may be formed by a housing of the electrical component, so that the

Luminous module on the housing, in particular on one or more of the outer surface forming side surfaces of the

Housing, the electrical component can be attached. The electrical component is for example as a

Ballast formed, which serves to control the one or more lamps of the light module. The

Illuminant may be a light-emitting element. A light-emitting element may be one or more

inorganic light emitting diodes (LED) and / or one or more have organic light-emitting diodes (OLED). Alternatively or additionally, the light-emitting element may comprise one or more laser diodes. The illuminant may be formed flat. The one or more lamps are mounted on the circuit board of the light module, wherein the

Printed circuit board serves as a circuit carrier. The electrical connection of the electrical component with the light module can be done via the circuit board of the light module by, for example, on the circuit board one or more

Contact elements are arranged, which are electrically arranged on the electrical component contact elements

can be connected. The electrical connection between the light module and the electrical component can thus be done directly without intermediate elements. The lighting system is characterized by a reduced installation effort, since in a mounting step, the light module can be connected to the electrical component and fastened, the safety requirements, especially in terms of clearance and creepage distances, can be met. Due to the fact that now the electrical component is no longer arranged at a distance from the lighting module, the lighting system can also be dimensioned smaller than conventional lighting systems, so that a space-saving arrangement and assembly is possible. Also the effort to make a

Electrical connection between the electrical component and the light module can be reduced because a complex arrangement of wiring is no longer necessary.

To form the attachment of the electrical component to the light module, the electrical component

For example, have a groove, in which engages the light module. The groove, which in the form of an elongated

Recess is formed on the electrical component, can laterally on the electrical component, on the

Outer surface of the electrical component, for example, the outer surface of the housing of the electrical component may be formed. The light module can engage in the groove such that an edge region of the circuit board of the Light module is inserted into the groove. The groove allows a positive connection between the electrical component and the light module. The assembly of the electrical component with the light module can be done here very easily and quickly by the light module with his

PCB in the on the electrical component

formed groove is inserted so that the light module is held and fixed in the groove. As an alternative to providing a groove on the electrical component may be used to form the attachment of the

electrical component on the lighting module, the electrical component on an outer surface of the electrical component have a step on which the light module is placed and fixed. The step may be in the form of a projection on the outer surface of the electrical component, for example the outer surface of the housing of the electrical component. At this stage, the lighting module can be placed in such a way that an edge region of the printed circuit board of the lighting module rests on the stage. For fixing the light module on the step, the edge portion of the

Guide plate of the light module, which rests on the stage to be pressed against the step by a force on the circuit board in the direction of the step, for example, by another element applied.

Next, the electrical component by means of a

Fastener be attached to the light module. The electrical component can be used alone by means of

Fastener be attached to the light module. But it is also possible that the fastener

in addition to one on the electrical component

trained groove or step is provided. For example, by means of the fastening element, a force on the light module, for example, the circuit board of

Luminous module, are applied when the circuit board of the light module rests with an edge portion on the step, so that by means of the fastener on the step Overlying light module can be attached by pressing.

The fastening element may be formed, for example, as a clip or a bracket, which may, for example, partially surround the electrical component in order to be able to fasten the lighting module to the electrical component. The clip as well as the strap can be made from one

Metal or a plastic to be formed.

To form the electrical connection, the

electrical component with the light module via a

Plug connection to be electrically connected. The

Plug connection can provide a quick and easy electrical connection between the electrical component and the

Enable light module, whereby the assembly costs for the lighting system can be further reduced. When mounting or sliding the light module on the electrical

Component can be formed at the same time the connector and thus the electrical connection. The provision of wiring through individual wires or the provision of cables are therefore no longer necessary. moreover

allows the connector a quick and easy release of the electrical connection between the electrical component and the light module. The plug connection

also allows a mechanical and thermal connection of the light module to the electrical component without having to provide further elements. The connector can be arranged on the electrical component connector and one on the light module

arranged, connectable with the plug mating connector. Both in the plug and in the mating connector contact elements may be arranged, which by

Mating the plug with the mating connector can contact each other. To the formation of electrical

Connection between the light module and the electrical component can plug in a simple way electrically connected to the mating connector and thus

be contacted.

Alternatively, it is also possible that the connector has at least one arranged on the electrical component spring contact element, which for forming the electrical connection in at least one of the

Printed circuit board of the light module formed metallized bore can be inserted. When plugging in a

Spring contact element in a metallized bore can be formed an electrical contact between the spring contact element and the bore and thus the circuit board of the light module. This connector is characterized by a particularly space-saving design. The

Metallization of the bore can be formed in that the peripheral surface of the bore is coated or coated with a metal, which has a particularly good electrical conductivity.

The electrical component may be attached to a mounting surface, wherein the lighting module may be arranged spaced from the mounting surface. By the

spaced arrangement of the light module to the

Mounting surface can be the required air and

Creepage distances are observed. The spaced arrangement forms a free space between the mounting surface and the light emitting module, which may for example be filled by a thermal insulator, such as air.

This is a little effort in the design of the lighting system possible to meet the safety requirements with respect to the creepage distances and creepage distances.

In order to achieve a particularly space-saving arrangement, the lighting module may for example be designed such that it at least partially surrounds the electrical component. The lighting module can encompass the electrical component such that the electrical component is arranged centrally of the lighting module. In order for the lighting module to at least partially surround the electrical component, the printed circuit board of the lighting module can be U-shaped, for example. During assembly, the electrical component can be inserted into the recess of the ^" egg-shaped printed circuit board, so that the circuit board of the light module, the electrical

Component on three side surfaces of the outer surface of the

can embrace electrical component.

Furthermore, the object is achieved by a lighting system which has at least one first lighting module, in particular as described above, and a second lighting module

Each of the two lighting modules has in each case at least one printed circuit board with a U-shaped recess, and wherein the lighting modules are designed in such a way that

at least one of the at least one U-shaped recess limiting web of the two lighting modules in

at least one U-shaped recess of the second lighting module is engageable or brought in particular in the assembled state.

As a result, a compact, modular expandable lighting system is created. U-shaped or comb-like structures may in particular be designed in such a way that they engage in one another in such a way that there are practically no intermediate spaces

remain. This can be achieved in three Lecuhtmodulen by the webs of two external lighting modules engage in the recess of a module located therebetween.

Advantageously, the first lighting module is electrically connectable or connected to the second lighting module via a plug connection. As a result, the structure is further simplified because the modules do not have to be soldered complicated.

It is useful if at least one of the components

Connector can also be used as a component of a connector to an electrical component as described above is. This ensures a universal usability of the module, because it can be connected to both an electrical component and with other modules. Furthermore, it is expedient for the plug connection to have a plug arranged on the first light module and a mating plug which can be connected to the plug and is arranged on the second light module. This allows a simple connection between the modules. The

Plug connection is preferred as above in the

Connection between electrical component and light module executed.
