Description

 Method for illuminating a light box

The invention relates to a method for controlling Leuchtmittelbetriebsgeraten to illuminate a

 Light box according to the preamble of claim 1. Furthermore, the present invention relates to a

 Lighting system for controlling at least two

 Illuminants for illuminating a light box according to the preamble of claim 2.

Technical field and state of the art

Lighting control and lighting management systems have become established as part of modern lighting solutions.

 Bulb operating devices of modern design, such as electronic ballasts for gas discharge lamps or operating devices for light-emitting diodes usually have interfaces, via the external control commands to the operating device

 can be transmitted. So can by appropriate

 Control signals, for example, a desired light intensity (dimming level) of the light source can be adjusted.

In the lighting industry, various standards have been developed for the control of light bulbs that differ in complexity.

 Technologically most advanced are digital solutions, where the Leuchtmittelbetriebsgerat has a digital interface,. via the digital control commands of one

Control unit can be sent to the bulb operating device. The communication can be bidirectional, ie the Leuchtmittelbetriebsgerat can not only recipients of

Signal commands, but also act as transmitters of signals. Thus, for example, the Leuchtmittelbetriebsgerat actively avoid a status report to the control unit when an error occurs.

For the transmission of the signals are known from the prior art a variety of ways: So is

Wired transmission (for example, by using the power supply line (Powerline) or using a separate from the power line pair) and wireless transmission (eg radio, infrared) possible. As an example for the control of light bulbs operating on the so-called DSI technology (by Tridonic) and the so-called DALI protocol (digital

addressable lighting interface). The DALI standard includes a comprehensive digital command set for

Communication with the Leuchtmittelbetriebsgerat provided. In a DALI-compliant lighting system is in addition to the Leuchtmittelbetriebsgerat with digital

Interface an associated bus device including a digital control unit necessary. In many cases, the user wants a less expensive technology that is a bit cheaper, but nonetheless provides the essential functionality. Thus, from the prior art, operating devices are known in which at the digital interface (control input) either a digital signal or a means of a with

Mains voltage supplied button generated signal can be applied. If the user does not want to use the digital peripherals, then optionally the digital control input of the operating device can be controlled by means of a push-button operation. For example, the duration and the

Repetition rate of the button operation evaluated as a signal for switching on and / or off or for brightness control (dimming). An example of such an operating device, to whose digital control input a signal generated by means of a mains voltage supplied with a button or switch is applied, is for example in DE 297 24 657

disclosed.

An application for the control of the operating device by means of push-button operation is in presence-controlled

Given lighting solutions, where the operating device by a

Motion detector is controlled. Such control gear, which is connected to one or more motion detectors, are for example in staircases, long corridors,

Underground garages, pedestrian underpasses or subway stations in use. If a movement is detected by a motion detector, for example due to the presence of a person, the operating device ensures that the corresponding room area is illuminated by the illuminant with a desired brightness (operating setpoint). In the absence of movement (absence), the bulb is dimmed to a resting value.

For certain bulbs such as

High-pressure gas discharge lamps is also a fast

successive switching off and on again not possible, since the lamp must first cool down before they

can be re-ignited. Presentation of the invention

Description of the preferred embodiments

Further advantages, features and characteristics of the present invention will now be explained with reference to the two appended drawings. Fig. 1 shows an arrangement of a lighting system according to the invention.

Fig. 1 shows a schematic representation of a

Lighting system (10), which may be arranged for example within a light box. The

 Illumination system (10) serves to control at least two light sources (Lal, La2). At least two operating devices (BG1, BG2) for operating in each case one light source (Lal, La2) are present. There may also be other operating devices (BG3, BG4), the far-ere

Drive light source (La3, La4). ■ The operating devices (BG1, BG2) each have a first interface. (IN11, IN12) and the first interfaces (IN11, IN12) are interconnected. The operating devices (BG1, BG2) also each have a second interface (IN21, IN22), and the second interfaces (-IN21, IN22) are each connected to a sensor (SEI, SE2). The second interface (IN21, IN22) can also be wireless

be educated. The operating devices (BG1, BG2) can transmit control signals via the first interface (IN11, IN12), which are dependent on the sensor signals detected via the second interface (IN21, IN22). It is also possible to receive control signals via the first interface (IN11, IN12). Furthermore, the lighting means (Lal, La2) can be controlled as a function of the sensor signals received via the first interface (IN11, IN12) and / or detected by the sensor via the second interface (IN21, IN22). The bulbs (Lal, La2) can in principle be any

Act light bulbs, such as gas discharge lamps or organic or inorganic light emitting diodes.

The illustrated operating devices (BG1, BG2) have connections to the earth, the phase conductor and the

Neutral can be contacted to the power supply of the operating device (BG1, BG2). As already mentioned, the operating devices (BG1, BG2) have a first interface (IN11, IN12) with the connections for connecting to a bus system (whereby this bus system does not necessarily have to be formed by a digital two-wire bus system, but also, for example, a system with one

Information transmission over the power line or via wireless communication). The first interface (IN11, IN12) can be designed so that digital commands can be transmitted to the operating device via these connections, for example, according to the DALI standard protocol or the operating device can send signals.

 Optionally or alternatively, the first interface (IN11, IN12) may be designed so that signals through the

 Supply voltage such as the mains voltage or also push-button signals can be transmitted.

The operating device (BG1, BG2) furthermore has a second interface (IN21, IN22). At this second interface (IN21, IN22), a sensor (SEI, SE2), for example, a brightness sensor or a

 Motion detector, to be connected. The respective use or usage of this second interface (IN21, IN22) can be programmable. In the case of the second

 Interface (IN21, IN22) supplied sensor signals, it may be. Signals to. A motion detector or a

 Brightness sensors act. Over the first interface (IN11, IN12) can a

 unidirectional or bidirectional communication between the operating devices (BG1, BG2) are enabled.

An operating device (BG1, BG2) can be supplied upon detection of a via the second interface (IN21, IN22)

 Sensor signal a communication with the other

 Operational unit (BG1, BG2). It can also be one

 Operating device (BG1, BG2) upon receipt of a signal transmitted via the first interface (IN11, IN12)

Evaluate sensor signal from the second interface (IN21, IN22). An operating device (BG1, BG2) can, upon receipt of a via the first interface (IN11, IN12) after evaluation of the

Sensor signal from the second interface (IN21, IN22) send a control signal via the first interface (IN11, I I2).

The lighting system can also have further operating devices (BG3, BG4) with at least one first interface (IN13, IN14). In this case, further operating devices (BG3) may be present, which also have a second interface (IN23), to which a further sensor (SE3) may be connected.

A bus coupler (BK) may also be present in the lighting system, which is connected to the first interfaces (IN11, IN12) and enables interface coupling to a higher-level control system (MS). It is possible to use the first interfaces (IN11, IN12)

various control signals are transmitted, wherein only a part of the transmitted control signals from the bus coupling unit (BK) to the higher-level control system (MS) are passed.

For example, DALI commands can be used as control signals

be transferred from the bus coupler (BK) to the

parent control system (MS) will be passed on. These control signals can be passed from the bus coupler (BK) directly as DALI commands to the higher-level control system (MS), or be converted into another protocol and then passed to the higher-level control system (MS). In addition, commands deviating from the DALI standard can be transmitted as control signals (for example according to a different protocol or in a protocol extended to the DALI standard), these control signals

preferably not be passed on from the bus coupling unit (BK) to the higher-level control system. Thus, a local control within the lighting system (10) with the operating devices (BG1, BG2, BG3, - BG4) within the

Light box or even within a room, this being done by means of monitoring by the various sensors (SEI, SE2, SE3), and it can be additionally received external control information from the parent control system (MS), such as on and

Off commands, as well as information about the status of the lighting system (10) (such as error messages or warnings) are transmitted from the lighting system (10) to the higher-level control system (MS).

As already mentioned, one illuminant may be an organic or inorganic LED and another may be a gas discharge lamp (fluorescent lamp).

High pressure gas discharge lamp) act.

The two bulbs can be arranged inside a luminaire. In this case, the two bulbs can be arranged within a luminaire (preferably advertising lighting) and monitoring by means of the first sensor (SEI) can take place within the luminaire and monitoring by means of the second sensor (SE2) can take place outside the luminaire.

An advertising lighting can be realized for example by means of a light box. This light box can be a transparent or

Partially transparent front and a reflective back or even have a transparent or partially transparent back. Also, the side walls can either as

reflective side walls or be designed as transparent or partially transparent side walls. Thus arise when using reflective side panels

(Side walls or back) Reflective means for the

Light box. Furthermore, the light box _{^ has} at least two light sources ^{ (hal, La2), wherein the light sources (Lal, La2) are preferably aligned such that the light emitted by the light sources (Lal, La2) and by the

Reflecting means Reflected light rays are radiated between the back and the front of the light box or on either side. The

semi-transparent side parts such as the

Front can be made from a diffuser disk.

By applying the method according to the invention or the illumination system, the light box can be regulated and optimally regulated as a function of the external brightness (detected by the sensor SE2) and also by the current brightness within the light box (detected by the sensor SEI)

be set.

This example of an inventive lighting system (10) will be explained in more detail below. The second operating device (BG2) can determine by the monitoring of the second sensor (SE2) when the ambient brightness (ie the external brightness) falls below a certain value (by monitoring the second sensor (SE2) via the second interface (IN22)). Now, the second operating device (BG2) according to the evaluation of the sensor signal (the second sensor (SE2)) adjust the control, preferably the brightness of the connected light source (La2) and / or on the first

 Interface (IN12) a corresponding control signal

 send out, whereby the others with the first

"Interface (IN11, IN31, IN41) via the bus system

 connected operating devices (BG1, BG3, BG4) this

 Control signal received.

Thus, the first operating device (BG1) receives this control signal via its first interface (IN11). Then it can detect the current value of the brightness within the light box by means of the first sensor (SEI), which is connected to the second interface (IN12).

Depending on the evaluation of the control signal received via the first interface (IN11) and the sensor signal detected via the second interface (IN12), the first operating device (BG1) can now operate the connected light source (Lal), for example, adjust its brightness. Furthermore, the first operating device (BG1) alternatively or additionally in evaluation of the received control signals and from the via the second interface (IN12) detected

Sensor signal also via the first interface _. (IN11)

Send control signal. This control signal can be received by the second operating device (BG2) (via the first

Interface (IN12)) and this can in response to the received control signal adjust the control of the light source (La2). Ί3

 Depending on how the parameters and thresholds for the

Monitoring of the sensors (SEI, SE2) can thus for the lighting system (10) within the

Light box the lighting can be regulated and optimally adjusted.

The dependence of the detected sensor signals can be interpreted in different directions and it can be set different operating modes for the individual lamps (Lal, La2).

The two bulbs can thus within a

Be arranged light box and it can be done by means of the first sensor (SEI) monitoring within the light box and by means of the second sensor (SE2) a

Monitor outside the light box.

According to this example, as the first sensor (SEI), a motion detector (for example, a passive infrared sensor, also referred to as PIR), a brightness sensor, a

Infrared sensor (for example, as a receiver for a

Remote control via infrared) or a color sensor

(For example, to adjust the color temperature, the

Color location or the emitted wavelength) or a combined sensor such as a brightness and motion sensor. Again, for the second sensor (SE2), for example, the application of a motion detector is conceivable, with perception of a movement in the vicinity of the light box bulbs (Lal, La2) can be switched on or changed their brightness accordingly. The monitoring within the light box can, for example, serve to compensate for brightness and / or color temperature (or also the color location or the emitted wavelength) as a result of aging of the lamps or else due to a

 Pollution can occur, even a brightness variation due to changes in temperature can thus be compensated (for example, a reduced efficiency of

Fluorescent lamps at low temperatures, for example at. Frost).

In the example shown in Fig. 1, the

Illumination system (10), for example, be designed so that at the first operating device (BG1) as the first sensor (SEI) an infrared sensor (for example, as a receiver for remote control by infrared, also called IR interface) connected to the second interface (IN12) , This infrared sensor can be used for the programming and address assignment of the illumination system (10) as well as for the specification of a desired brightness value. On the second operating device (BG2) can be used as a second sensor (SE2), a motion detector (for example, a passive

Infrared sensor, also referred to as PIR) may be connected to the second interface (IN22). On the third operating device (BG3) can as a third sensor (SE3) a

 Brightness sensor (for example, a daylight sensor, also referred to as DL interface) to be connected to the second interface (IN32) .. Thus, the brightness sensor may for example be arranged such that it

Ambient light, so the daylight detected. Depending on the detected ambient light (the environment (OS)), the

Brightness of the lighting system (10) can be adjusted. But it would also be possible that, for example, the

Brightness sensor as the third sensor (SE3), the sum of artificial light, which is generated by the bulbs (Lal, La2), and the ambient light to capture, so that the lighting system (10) is adjusted accordingly in its brightness. Alternatively, however, two separate brightness sensors could also be used, for example, one brightness sensor detecting the artificial light and another brightness sensor detecting the ambient light. In this case, it would thus be possible to connect the fourth sensor (as a further brightness sensor) to the fourth operating device (BG4), provided that this also has a second interface. The two bulbs can also within a

Be arranged room and it can be done by means of the first sensor (SEI) monitoring within the room and take place by means of the second sensor (SE2) monitoring outside the room. According to this example, the first sensor (SEI) may also be a motion detector (for example a passive infrared sensor, also referred to as PIR)

Brightness sensor, an infrared sensor (for example, as a receiver for remote control via infrared) or a

Color sensor (for example, to adjust the color temperature, the color locus or the emitted wavelength) or a combined sensor such as a brightness and motion sensor are applied. Again, for the second sensor (SE2), for example, the application of a motion detector is conceivable, wherein upon perception of a movement in the environment of the room (ie outside) the bulbs (Lal, La2)

can be switched on or changed in their brightness accordingly. Since several operating devices (BG1, BG2, BG3) can be present, all of which have a second interface (IN21, IN22, IN23), it is also possible to combine different individual sensors (SEI, SE2, SE3), and thus in a simple manner a very flexible and powerful

Lighting system to be built.

Thus, a method for controlling at least two light sources is made possible, wherein two light sources (Lal, La2) are each operated by one operating unit (BG1, BG2),

 v

the operating devices (BG1, BG2) are interconnected via one interface each (INli, IN12), and the

Operating devices (BG1, BG2) in each case have a further interface (IN21, IN22), and wherein the operating devices (BG1, BG2) send control signals via the first interface (IN11, IN12), which are transmitted via the second interface (IN21, IN22). detected sensor signals are dependent, and the

Illuminant (Lal, La2) depending on the received via the first interface (INll, IN12) and / or from the via the second interface (IN21, IN22)

Sensor signals are controlled.

In summary, the invention discloses an improved control of a bulb operating device, which is characterized in that it can adapt flexibly and dynamically to different situations.
