Description of the Preferred Embodiments Further advantages, features and characteristics of the

Present invention will now be explained with reference to the two accompanying drawings.

Fig. 1 shows an arrangement of a lighting system according to the invention

Fig. 2 shows another possible arrangement of a lighting system according to the invention Fig. 1 shows a schematic representation of a

Lighting system (10) for a room.

The illumination system (10) has at least two

Bulb (Lal, La2) on. In this case, there are at least two operating devices (BGH, BG21) for operating in each case one lighting means (Lal, La2).

a control unit (SGI) is connected to the operating devices (BGH, BG21) in each case via a control line (BUS1, BUS2). The control unit (SGI) is connected to at least one control center (ZE1). The control center (ZE1) can address the controller (SGI) via various addresses. Each control line (BUS1, BUS2) is assigned its own address and the control unit (SGI) also has an additional address via which all control lines (BUS1, BUS2) can be addressed.

Preferably, the communication is done by the

Control center (ZE1) to the control unit (SGI) via a DALI bus line. On the other hand, the control lines (BUS1, BUS2) are preferably arranged according to another one ^.

Transmission protocol, for example the Tridonic

Protocol DSI designed.

In this way, the installer does not have to worry about how to program or assign the individual operating devices. The assignment is made via the connection to the respective control line (BUSl, BUS2), wherein the

Assignment of the addresses, for example, is already determined by a pre-programming. The control center (ZE1) preferably has one

integrated supply circuit to feed the bus line. But it can also be provided externally to the control center (ZE1) a bus line feed.

Furthermore, the control unit (SGI) also more

Interfaces (bus lines), for example, in turn, for a DALI BUS, and thus can also address other control devices (SG2). Thus, a larger network of control devices and operating devices can be formed, whereby the number of required addresses can be kept limited. The control units (SGI, SG2) can be linked in different arrangements (star topology, tree arrangement,

Line arrangement - daisy chain, or similar).

The controller (SGI) may also be formed by the combination of a plurality of controllers (SGla, SGlb) arranged within a common housing.

The connections to the controller (SGI) for the

Control lines (BUS1, BUS2) and the others

Interfaces (bus lines) may differ in their mechanical structure, so that a faulty installation can be avoided. Also, an exchange of individual operating devices (BG1) is very simple, since no change to the system or new address assignment is required, it must only be replaced the operating device. The other interfaces of the control unit (SGI) can also be used to connect different sensors (SEI, SE2). The sensors (SEI, SE2) can detect at least two different types of sensor signals. The control units (SGI, SG2) can transmit control signals via the control line (BUS1, BUS2) depending on the sensor signals detected by the sensors (SE1, SE2).

The operating devices (BGH, BG21) can send control signals via the control line (BUS1, BUS2). Furthermore, the lighting means (Lal, La2) can be controlled as a function of the control signals received via the control line (BUS1, BUS2).

The bulbs (Lal, La2) may in principle be any illuminant, such as gas discharge lamps or organic or

inorganic light emitting diodes.

The illustrated operating devices (BGH, BG21) have connections which can be contacted with the earth, the phase conductor and the neutral conductor for the power supply of the operating device (BGH, BG21). As already mentioned, the operating devices (BGH, BG21) have connections for connection to a control line (BUS1, BUS2) (although this control line 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 control line (BUS1, BUS2) can be designed so that these commands to the operating device digital commands, for example. According to the DSI protocol of the company Tridonic can be transmitted or the operating device can send signals. Optionally or alternatively, the

Control line (BUS1, BUS2) be designed so that Signals can be transmitted through the supply voltage such as the mains voltage or push button signals.

Over the control line (BUS1, BUS2) can thus a

Communication between the control unit (SGI, SG2) and the operating devices (BG1, BG2) are made possible. These

Communication can be both unidirectional as well

bidirectional.

It can at the sensors (SEI, SE2) in each case to

Brightness sensors and / or motion detectors act. The sensors (SEI, SE2) can be used as sensors with

Single function or be designed as so-called combination sensors. The combination sensors can have at least one movement as well as the brightness for one

capture specified area.

By means of the first sensor (SEI), the brightness can be monitored within a first area of the room, and the second sensor (SE2) can be used to monitor the brightness within the second area of the room. In addition, as a further sensor, a motion detector can be connected to the control unit (SGI, SG2)

be connected. For example, on the

Approach or presence of a person to be responded and the brightness in the light box upon detection of an approach or presence of a person can be increased. The control units (SGI, SG2) can transmit control signals via the control line (BUS1, BUS2) if a brightness change has been detected by means of the sensors (SEI, SE2) and the control units (SGI, SG2) can Send control signals via the control line (BUS1, BUS2) and additionally via the interconnected interface (PIR LINK), if by means of the sensors (SEI, SE2) movement was detected.

The control unit (SGI, SG2) can optionally perform an evaluation of the time of day based on the course of the ambient brightness and adjust the control of the operating devices (BGH, BG21) to the recorded time of day.

The control unit (SGI, SG2-) can optionally be

be provided additional connection for a button control. In this case, a button between the terminal for the button control and the phase connection of the network or another voltage source may be connected. The control unit (SGI, SG2) can detect the actuation of the button and adjust its behavior accordingly.

For example, by a longer actuation of the button, a brightness change in the light sources (Lal, La2) can be effected. It can also be one

selective switching on or off can be effected

in particular by a momentary push-button operation.

In addition, a default or selection of

Operating parameters such as the

Switch-on brightness or a target brightness at

Detecting a movement by means of a button operation done.

The lighting system can also have other operating devices (BG12, BG22) which are connected to a control device (SGI,

SG2) are connected via a control line (BUS1, BUS2). In this case, other operating devices (BG31) may be present, with a further control unit (SG3) via a Control line (BUS3) are connected, whereby this further control unit (SG3) optionally another

additional sensor (SE3) can be connected. There may be a Busankoppler (BK), which is connected to at least one control unit (SGI, SG2) and enables an interface connection to a higher-level control system. But it can also be a controller (SGI, SG2) directly interfacing with a parent

Enable tax system.

Various control signals can be transmitted via the control line (BUS1, BUS2), with only a part of the transmitted control signals from the bus coupling unit (BK) or the control unit (SGI, SG2) to the higher-level control unit

Tax system is passed.

For example, DALI commands can be transmitted as control signals issued by the. Bus coupling (BK) to be given to the parent control system. These control signals can be passed from the bus coupler (BK) directly as DALI commands to the parent control system, or be converted into another protocol and then to the parent

Tax system to be shared.

In addition, deviating commands can be transmitted as control signals from the DALI standard (for example, according to a deviating protocol), these control signals not being sent from the bus coupling unit (BK) to the higher-level

Control system will be given. The bulbs may be an organic or inorganic LED, or a gas discharge lamp

(Fluorescent lamp, high-pressure gas discharge lamp) act. But it can also be different bulbs, for example, it can be at a

Illuminant to an organic or inorganic LED act and act in another to a gas discharge lamp (fluorescent lamp, high-pressure gas discharge lamp). The two bulbs are inside the room

arranged.

The illumination can preferably serve to illuminate a classroom and it can by means of the first sensor (SEI) monitoring the brightness within a first range. of space and by means of the second

Sensors (SE2) to monitor the brightness within the second area of the room. The nature of

Sensor signals can be distinguished, for example, based on the nature of the detected change. For example . it is possible to distinguish between a detection of brightness information and the detection of a movement. In addition, an operating device (SCI) can be connected to at least one control device (SGI, SG2). It can also be connected to several or all of the control units (SGI, SG2) each operating devices (SCI, SC2).

Thus, according to the invention, efficient lighting can be realized by means of a room.

Fig. 2 shows a view of a typical construction of a lighting system of a room according to the invention. The illumination system according to FIG. 2 has several

Control units (SGI, SG2, ..) on which the control, preferably the brightness of the connected

Control gear (BG21, BG22) with the bulb (Lal, La2, not shown in FIG. 2) adapt. The

Operating equipment (BG21, BG22, BG23, etc.) and the

Lamps (Lal, La2) are preferably each in a lamp (lights, lamp22, lamp23, etc.)

accommodated.

As already explained, the illumination system has at least two light sources (Lal, La2), the light sources (Lal, La2) preferably being aligned in such a way that the space illuminated by the light sources (Lal, La2) is uniformly illuminated. This uniform

Lighting is basically given when no light enters through the windows (i.e.

Ambient brightness as in the night or at

closed shutters or blinds).

By using the method according to the invention or the illumination system, the individual areas of the room can be regulated and optimally adjusted as a function of the brightness of the respective monitored area. Thus, can be a very energy efficient

To reach the lighting of a room.

This example of an inventive

Illumination system (10) will be described in more detail below

be explained. The second control unit (SG2) can detect by the monitoring of the second sensor (SE2), if the brightness in the vicinity of the windows (where the ambient brightness can act as external brightness) one

certain value falls below. Now the second control unit (SG2) according to the evaluation of the

Sensor signal of the second sensor (SE2) via control line (BUS2) emit a corresponding control signal and by means of the operating devices (BG21, BG22) the control, preferably the brightness of the connected

Adjust the bulb (La2) in the luminaires (Luminaire21, Luminaire22, Luminaire23).

Furthermore, the first controller (SGI) may detect the current value of the brightness within the range remote from the windows by means of the first sensor (SEI) connected to the controller (SGI).

Depending on the evaluation of the connected sensors (SEI, SE3), the control unit (SGI) can use the

Control line (BUS1) send out corresponding control signals and the operating devices (BGH, BG12) can accordingly operate the connected light sources (Lal) in the luminaires (Leuchteil, Leuchtel2, Leuchtel3),

for example, adjust their brightness. The others in the lighting system (10)

arranged operating devices (BG31) may each be connected to a control unit (SG3) and receive control signals from this. Thus everyone receives Further operating devices (BG3) a control signal via a control line (BUS3).

According to the invention, the control devices (SGI, SG2) are interconnected via an interface (PIR LINK).

The sensors (SEI, SE2), which are each connected to a control unit (SGI, SG2), can next to a

Brightness sensor also contain a motion detector. The sensors (SEI, SE2) are thus, as already explained, preferably combination sensors which can detect at least one movement as well as the brightness for a predetermined area. Alternatively, several individual sensors may be connected to the control units (SGI, SG2), each sensor having only one function, such as the

Brightness monitoring or motion detection takes over.

Thus, for example, a plurality of sensors (SEI, SE3) can be connected to a control unit (SGI).

If a movement in the room is detected by means of the sensors (SEI, SE2), then the corresponding control unit (SGI, SG2) sends control signals via the control line (BUS1, BUS2) and additionally via the interconnected ones

Interface (PIR LINK). This is transmitted via the interconnected interface (PIR LINK)

Control signal receive the other control unit (SGI, SG2, SG3) and then send corresponding control signals via their control line (BUSL, BUS2) to the

connected control gear (BGH, BG21). Thus, for the presence of a person in the room, an optimal and energy-efficient brightness adapted to the individual areas of the room can be achieved, while leaving the room, the lighting

can be switched off.

Depending on how the parameters and threshold values for the monitoring of the sensors (SEI, SE2) are designed, the lighting can thus be regulated and optimally adjusted for the lighting system within the room (10).

The dependence on the detected sensor signals can be interpreted in different directions and it can be different operating modes for each

Illuminant (Lal, La2) are set.

As already mentioned, motion sensors can be used as sensors (SE2, SEI, SE3) or other (additional) sensors

(For example, a passive infrared sensor, also referred to as PIR), brightness sensors, infrared sensors

(For example, as a receiver for a remote control by infrared) or color sensors (for example, to adjust the color temperature, the color locus or the emitted wavelength) or combined sensors such as a

Brightness and motion sensor are applied. When using a motion detector, it should be noted that the detection of a movement is also to be understood as the detection of the leaving of a monitored space, that is to say a repeated interrogation of the Motion detector instead. As long as a person is present, the motion detector outputs a presence signal. If no presence is detectable, ie the room was left, this leaving the room can be signaled. When a movement in the monitored area of the room is detected, the light sources (Lal, La2) can be switched on accordingly or in their

Brightness can be changed. Since several luminaires (Leuchteil, Leuchtel2, Leuchtel3) and thus operating devices (BGH, BG12, BG13) can be present, all via a control line (BUS1)

can be controlled, it may be advantageous if several different individual sensors (SEI, SE3) are connected to a control unit (SGI), and thus can be easily constructed a very flexible and powerful lighting system for a room with multiple lights.

A shutdown of the lighting means (Lal, La2) in case of detecting the leaving of the room can be done over a switch-off delay time. Thus, for example, the control unit (SGI, SG2) can wait a predetermined period of time, ie the switch-off delay time, upon determining the state of leaving the room, and only then issue a switch-off command as a corresponding control signal via the control line (BUS1, BUS2) to the connected operating devices (BGH, BG12, BG21, BG22).

The turn-off delay time may optionally be at the

Control unit (SGI, SG2) are set. This can be done, for example, by programming, for example via an interface, or by means of a manual specification, for example by means of a rotary switch or DIP switch. Alternatively, however, the control gear (BGH,

BG12, BG21, BG22) upon receipt of a switch-off command wait a predetermined period of time, ie the switch-off delay time, and then switch off the light sources (Lal, La2).

Additionally or alternatively, when switching off the lighting means (Lal, La2) in the case of determining the leaving of the room first, a change of the brightness to a lower brightness and only then

Switch off the lamps (Lal, La2) done. In this case too, these steps can preferably be predetermined by corresponding control signals of the control devices (SGI, SG2), but alternatively these steps can also be stored in the operating devices (BGH, BG12, BG21, BG22) and by a corresponding control signal by the control devices (SGI, SG2) are triggered.

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