ARRANGEMENT FOR OPERATING LUMINAIRES The present invention relates to an arrangement for operating illuminants, for which purpose a control device or an operating device for controlling the illuminants is used, in which a so-called corridor function is implemented.

The corridor function mentioned above is understood to mean that automated control of the lamps is achieved using a sensor. The sensor is, in particular, a motion detector, with the aid of which movements of people or generally the presence of people in an area to be illuminated can be detected. If a movement is detected, the control device is prompted by the sensor to set the brightness level of the illuminants to a predetermined level during a predetermined period of time. This level can be 100% of the light output, for example, and the time period can be set depending, for example, on a delay time which is implemented in the sensor and / or the operating device. Through these measures, which can be provided, for example, in the lighting of stairwells or parking garages, lighting can be achieved throughout the day with relatively little effort and with reduced energy, and always when it is actually needed. However, in phases in which no people are recognized within the area to be illuminated, the lighting is deactivated so that there is no unnecessary loss of energy.

Starting from the prior art described above, the present invention is based on the task of expanding the possibilities for controlling the lamps, but keeping the effort for this as low as possible.

The object is achieved by an arrangement for operating lamps with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

According to the present invention, in addition to the light control described above, a further possibility for control via a preferably manually operated switch or button is provided based on a signal, for example, a motion detector. In this case, two switching elements are connected on the input side to the operating device for controlling the lamps, a first switching element preferably being controlled by the sensor and a second switching element preferably being able to be actuated manually. Depending on the state of both switching elements, the lamps are then controlled, in particular three different operating states for the lamps being able to be controlled.

According to the invention, an arrangement for operating lamps with an operating device for controlling the lamps is proposed, which is connected on the input side to a first and a second switching element, the operating device in the event that

a) both switching elements are open which operates the illuminant in a first operating state,

b) the first switching element is closed, the illuminant operates independently of the switching state of the second switching element in a second operating state, and

c) the first switching element is open and the second switching element is closed, which operates the illuminant in a third operating state.

With relatively simple measures, which are particularly the subject of the dependent claims, there is now the possibility to operate the lamps in three different operating states. The first operating state is preferably a / 7

State in which the lamps are deactivated. In the event that neither the manually actuated switching element is actuated nor a positive signal is output by the sensor, the lamps are deactivated to avoid energy losses.

The second and the third operating state, however, correspond to different brightness levels of the lamps, the second operating state, which is activated as mentioned above by the sensor preferably provided, preferably corresponds to a maximum brightness of the lamps. The third operating state, on the other hand, which is achieved by manually actuating the second switching element, preferably corresponds to a reduced brightness of the illuminants of, for example, approximately 10% of the maximum brightness. It can in particular be advantageously provided that the illuminants are LEDs and the third operating state is achieved with a reduced brightness by activating only a part of the LEDs.

The operating device preferably has a supply voltage input and a further input for controlling the sensor signal. It is preferably provided here that the sensor-controlled switching element opens or closes both supply lines to the two inputs of the operating device. In the event that no signal is output by the sensor, the control gear is completely disconnected from the power supply. In contrast, in the event that motion is detected, the power supply for the operating device is provided and a signal is present at the corresponding control input of the device. The second, manually operated switching element, on the other hand, is designed in such a way that it likewise optionally only provides the operating device with a voltage supply. The corresponding branch is in this case designed in parallel with the voltage supply branch of the first switching element. This means that the operating device operates the lamps in the event that voltage is present at the voltage supply input and at the control input of the operating device, in the above-mentioned second operating state, in particular at maximum brightness, while, in contrast, for the case that only voltage at the voltage supply input is caused by the second switching element - is applied, the lamps are operated in the third operating state with preferably reduced brightness. As already mentioned, this allows the three operating states for the lamps to be controlled in a simple manner, the outlay for this being reduced to a minimum.

The first switching element can both be integrated directly into the sensor and, for example, be designed as a relay which is triggered by a control signal of the motion sensor, the corresponding control signal then being supplied by the sensor via a corresponding control line.

The arrangement according to the invention can in particular be provided for realizing an emergency lighting device which has a so-called “maintained-mode emergency lighting” function. This means that the emergency lighting device is used for normal lighting in the non-emergency lighting case. The normal lighting corresponds to the sensor-controlled operation of the lamps at maximum brightness, whereas, in the event of an emergency, the reduced brightness is controlled with the aid of the second switching element.

The invention will be explained in more detail with reference to the accompanying drawing. 1 shows schematically the configuration of an operating device according to the invention for operating lamps and its control.

The arrangement according to the invention shown in FIG. 1 and generally provided with the reference numeral 100 is used to operate lamps, in the present case it is preferably an arrangement of a plurality of LEDs 200 which are arranged, for example, in the form of a so-called serial-parallel array are. In this case, several strings of LEDs arranged in series are provided, which are connected in parallel to one another. However, the concept according to the invention is not limited to LED control, but can also be used with other types of light sources.

Patent Office [0014] An essential component of the arrangement 100 is first of all an operating device CLE, 50 which converts a supply voltage present on the input side into a voltage suitable for operating the illuminants 200. The power supply to the operating device 50 takes place via two connections N and L, which are connected to the corresponding lines or wires of a power supply cable.

A third input connection CF of the operating device 50 is used to control the so-called corridor function mentioned at the outset, which therefore enables the lighting means 200 to be temporarily activated as required. Such functionality can be used, for example, to illuminate corridors, stairwells or parking garages. The automated control is supported by the use of a sensor 10, which can be formed in particular by a motion detector, for example in the form of a PIR sensor (passive infrared sensor) and which controls a first switching element SW1. This switching element SW1 is - as shown - designed as a two-pole switch and connected on the input side to the mains supply voltage, on the output side on the one hand to the voltage supply input L of the operating device 50 and on the other hand to the control input CF.

The inventive extension of this corridor function, which is already known from the prior art, consists in the use of a second switching element SW2, which can be operated manually, for example, and can be designed as a switch or as a button. The arrangement of this second switching element SW2 is such that, depending on its switching state, it also connects the mains supply voltage to the input L of the operating device 50 in parallel to the first switching element SW1.

The arrangement and configuration of the two switching elements shown in FIG. 1 therefore has the result that, in the event that both switching elements SW1 and SW2 are open, neither a supply voltage at the corresponding terminal L of the operating device 50 nor a corresponding signal on Control input CF is present. In this case, the illuminants 200 are deactivated or they are operated in a first operating state, which corresponds to an off state.

In contrast, in the event that the first switching element SW1 is activated by the sensor 10, voltage is present both at the voltage supply input L of the operating device 50 and at the control input CF regardless of the state of the second switching element SW2. This is interpreted by the operating device 50 in such a way that the illuminants 200 are to be operated in a second operating state, which corresponds, for example, to 100% of the brightness. This corresponds to the corridor function mentioned above, namely that, if required, the control device 50 is triggered by appropriate activation of the sensor 10 to operate the lamps 200 at maximum brightness. The duty cycle for the illuminants 200 can be set in a corresponding manner either by the sensor 10 or by the operating device 50. This duration can be dependent, for example, on the frequency of the movements detected by the sensor 10 or can also be predetermined constantly.

If, on the other hand, no movement is detected by the sensor 10 and the first switching element SW1 is accordingly open, only a supply voltage is present at the connection L of the operating device 50 when the second switching element SW2 is activated or closed. On the other hand, no signal is detected at the control input CF, which is now interpreted according to the invention by the operating device 50 such that the lamps 200 are to be operated in a third operating state, which is characterized by a different brightness level than in the second operating state. In this third operating state, there is therefore preferably a reduced brightness of the illuminants 200, which is, for example, approximately 10% of the maximum brightness.

In certain situations, a reduced brightness of the illuminants 200 can be set as required using the second switching element SW2. This may be necessary, for example, if security checks have to be carried out at certain times, for example in hospitals or other public places

Facilities may be the case. It would also be conceivable to implement emergency lighting in this way by the second switching element SW2 being switched on by an emergency system in order to ensure permanent lighting at a certain basic level in the event of an emergency.

The switching element SW1 can be both integrated directly into the sensor 10 and, as shown, for example in the form of a relay which is triggered by the sensor 10 on the basis of a control signal. In this case, the sensor 10 is then connected to the switching element SW1 via a control line 11.

According to the invention, three different operating states of the illuminants 200 can thus be controlled with the aid of the arrangement according to the invention, preferably two of the operating states relating to a specific predetermined brightness of the illuminants. In particular, it can be provided that in the third operating state, which is triggered by actuation of the second switching element SW2, the reduced brightness of the illuminants 200 is achieved by only activating a part of the LEDs. As a result, these LEDs can still be operated under optimal operating conditions, so that the energy expenditure for achieving this operating state is kept as low as possible.

Ultimately, with the help of the solution according to the invention, the possibilities for operating illuminants in different operating states are expanded, these advantages being obtained with very little additional effort.
