Description

The present invention relates to a system for accent lighting or to produce lighting effects, comprising a central control unit, a plurality of control devices, a plurality of voltage converters and a plurality of LED strings, the LED strings each having at least one LED and for controlling and powering the LEDs to the control devices are connected and wherein each control device is assigned at least one LED string. At the same time each control device is associated with a voltage converter, wherein the voltage converters are connected to a supply line and are adapted to supply the control devices with a voltage different from the voltage of the supply line. The central control unit then serves to control the control devices, wherein the control devices are connected via a data line to the central control unit.

LEDs are used more and more often in the most diverse areas of lighting technology. Thus, for example, diverse light effects can be realized in a simple manner with such modern light sources. Since LEDs can be relatively easily changed in their brightness, it is possible to generate a mixed light in almost any hue or any color temperature when using different color LED-based light sources by adjusting the intensity of the respective color. Compared to classical light sources such as incandescent lamps or fluorescent lamps, in which color effects could be generated primarily by the use of appropriate filters, accordingly, a light output can be generated in a much more effective manner. Since LEDs can also be realized significantly more compact in terms of their dimensions, it is now possible, for example, to arrange a multiplicity of LEDs in the form of a matrix or the like and to achieve video-like effects by correspondingly coordinated activation of the LEDs.

A comfortable generation of such lighting effects is particularly possible if the LEDs are integrated into a larger system and these are controlled centrally. In this connection, various possibilities are known from the prior art to form larger such lighting systems. In 1 By way of example, such a system is shown schematically, wherein a central control unit or video control unit (VCU) 5 with multiple control devices or streaming / segment control units (SCUs). 1 connected is. In addition to every SCU 1 at least one LED string 2 connected, which has several LEDs 3 having. The LEDs 3 are connected to each other via a corresponding line, resulting in elongated LED strands 2 result.

These LED strands 2 can then be arranged, for example, parallel to each other, resulting in a matrix-like structure of all LEDs 3 results and makes it possible to achieve video-like effects. But then it is also necessary that the LEDs 3 each individually controlled or controlled. This is done by the SCUs 1 to the LED strings 2 and thus the LEDs 3 are connected. In order to achieve video-like effects over the entire matrix-like arrangement, it is additionally necessary to control or drive the LEDs 3 , which to different SCUs 1 are connected, coordinated or coordinated. For this is then the VCU 5 responsible, the appropriate control commands to the SCUs 1 transmitted or the SCUs 1 accordingly controls or controls.

Instead of the parallel and thus matrix-like arrangement of the LED strings 2 but other arrangements are conceivable. For example, it could be provided that each SCU 1 an LED string 2 is connected, with the LED strands 2 then successively arranged in a long line, for example, around a building. Again, it is desirable, the LEDs 3 individually to control or to achieve appropriate lighting effects.

The SCUs 1 and the VCU 5 are connected to each other regardless of the arrangement via a video data line or data line, for example, it may be provided that each SCU 1 has a data input and a data output and thus a first SCU 1 directly to the VCU 5 is connected and all other SCUs 1 are each interconnected via the data line. Alternatively, it is also conceivable that the data line is a bus line to which the SCUs 1 in each case only be coupled accordingly.

The power supply of the SCUs 1 and the LED strands 2 or LEDs 3 done as in 2 shown by additional voltage converter or driver 4 where each SCU 1 a voltage converter 4 assigned. The voltage converter 4 are connected to a supply line with 230 V and convert this voltage to 24 V, that of the respective SCU 1 is made available. The SCUs 1 in turn, then convert the 24V to a voltage using the LEDs 3 can be operated accordingly, for example, 5 V. Thus, in the in 1 and 2 shown system via the data line only the corresponding control information for the LEDs 3 transmitted. The current or voltage supply of the SCUs 1 occurs via the respectively assigned voltage converter 4 , which are connected to the supply line. The voltage provided by the voltage converters is provided by the SCUs 1 then also to the current or voltage supply of the LEDs 3 used.

In the in the 1 and 2 shown system is previously provided that the SCUs 1 and voltage converters 4 For example, each are arranged in a correspondingly large housing, said housing separately from the LED strands 2 is arranged, since due to the size of sufficient space must be available for the housing. However, this often leads to the use of such systems, for example in the facade cladding to space problems, since in house facades usually not enough space for such housing.

The present invention is therefore based on the object that in the 1 and 2 shown system further developed so that the space requirement is reduced and thus a use in a small space is possible.

Additionally, an elongated rail may be secured to the open side of the U-shape of the elongate profile on which the LED strands are disposed. The elongate rail can in this case be detachably fastened to the elongate profile, in particular by latching or clamping element.

Preferably, the elongated rail is H-shaped in cross section, wherein on the side on which the LED strands are arranged, an optical element for influencing the light is provided.

Furthermore, it can be provided that each control device has an input connection and an output connection for the data line, in which case a first control device can be connected directly to the central control unit and the other control devices can each be connected to one another via the data line.

Thus, by attaching boxes in which the control devices and voltage converters are arranged, the present invention enables a system for accent lighting or for producing accent lighting on the side of an elongated U-shaped profile in which the LED strands are arranged Lighting effects, which requires very little space and thus can be used, for example, in house facades, where little space is available.

The SCUs 1 serve to control and power the LEDs 3 , where like out 2 shows, every SCU 1 a voltage converter or driver 4 assigned to a corresponding supply line with 230 V is assigned.

The voltage converter 4 converts the voltage from 230 V to 24 V and sets this voltage of the respective SCU 1 to disposal. This is then designed to convert the 24 V into a voltage that is suitable for supplying power to the LEDs, for example 5 V. The SCUs 1 thus supply the LEDs 3 with a voltage of 5 V and can simultaneously also each LED 3 correspond to taxes or taxes.

To have a coordinated control of all the different SCUs 1 connected LEDs 3 to allow, is then further provided that the VCU 5 the SCUs 1 corresponding control commands transmitted or the SCUs 1 accordingly controls or controls. Thus, for example, results in a parallel and thus matrix-like arrangement of the LED strands 2 the possibility of displaying video-like effects with the help of the system.

As previously explained, it is now provided in the prior art that each SCU 1 together with the corresponding voltage converter 4 is arranged in a large housing, which, however, must be arranged separately due to the size.

This is achieved in particular by the fact that relatively small boxes 12 each directly on the side of the elongated U-shaped profile 11 in which or on which the LED strands 2 , Supply line and data line run, are releasably secured. Thus, it is only necessary that in the area where the boxes 12 each on the elongated U-shaped profile 11 are attached some space to provide. However, it is no longer necessary, the relatively large known from the prior art housing with the SCUs 1 and voltage converters 4 to arrange separately and to provide a corresponding large space each for each of these housing.
