description
OPERATING DEVICE FOR GAS DISCHARGE LAMPS
The present invention relates to the operation of lamps such as fluorescent lamps and gas discharge lamps. In particular, the invention relates to an operating device or an electronic ballast which has an input interface to which a light sensor for monitoring the brightness can be connected, and to methods for using this input interface.
It is already known from EP 0 965 252 B1 basically that an electronic ballast for operating a lamp has a connection device to which a light sensor for monitoring the brightness of a specific spatial area can be connected. The light sensor used for brightness control detects brightness actual values in a region illuminated by a lamp. These brightness actual values are fed to the operating device via this connection device. The lamp whose brightness is detected by the light sensor is controlled by this operating device according to the brightness actual values or the lighting is dimmed.
Parallel to this first connection device, the electronic ballast has more connections for receiving external control information eg. Via a bus line. The electronic ballast can be supplied with various information or commands such as external dimming setpoints. Furthermore, switch-on or switch-off commands for the electronic ballast can be transmitted via the control connections.
It should be noted that this measuring connection device is used to connect light sensors or brightness-dependent resistors. If a light sensor is connected to the device, this is checked by the operating device and detected, so that the brightness of the lamp can be adjusted or dimmed according to the sensor value. The external control information regarding the brightness of the lamp are not taken into account in this case for the operation of the lamp.
If no light sensor should be connected to the electronic ballast, however, the operating device can be controlled via the other digital control connections such as DALI or DSI connections. Due to the low signal transmission rate of such digital connections or interfaces, connected lamps can not be controlled by means of external control information to rapidly changing brightness actual values. Therefore, it is not possible according to this prior art to realize lighting effects with very fast light changes.
The invention has accordingly set itself the task of providing an improved technique for operating a lamp, which also fast light changes can be realized.
The object is solved by the characterizing features of the claims, wherein the combination of claims is characterized as a particularly advantageous solution to the problem.

The potentiometer can be used for manual dimming and / or switching on and off of the lamp.
The operating device can in particular automatically detect whether a light sensor or a potentiometer is connected to the cutting part input.
The automatic detection between the light sensor and potentiometer may have the following steps: the operating device performs at least one change in brightness of the associated light source, and changes in the signal received via the interface input signal is closed to a light sensor, otherwise a potentiometer.
The switching between a passive and active mode in the case of a passive or active signal can be made via a digital control connection, in particular via a DALI or DMX control connection.

Illuminant, and - the second operating device demodulates the light detected by the photo element to recover the information transmitted by the first operating device.
Preferably, the brightness and / or the frequency of the light of the first lighting means is modulated, detected, and demodulated.

The operating device has a first interface input for connecting a light sensor and a second control input for receiving control information. The type of information that is supplied to the operating device via the first interface input can be defined via the second control input.
According to a further aspect of the present invention, a system for wireless communication between two operating devices for lighting means is provided.

The invention will be described below with reference to preferred embodiments with reference to the accompanying drawings.
1 schematically shows a preferred embodiment of a system according to the present invention, [0032] FIG. 2 shows schematically another embodiment of a system according to the present invention with the use of a potentiometer, and [0033] FIG. Fig. 3 and Fig. 4 schematically another particularly for a wireless communication kations advantageous embodiment of a system according to the present invention.
Fig. 1 is a schematic representation of an embodiment of a system 1 according to the present invention. The system 1 essentially comprises an operating device 2 for operating one or more lamps 3. The operating device 2 may be, in particular, an electronic ballast 2 for at least one lamp 3, in particular for at least one fluorescent lamp such as a gas discharge lamp. However, the bulbs may also be, for example, light-emitting diodes.
The electronic ballast 2 shown has inputs 4a and 4b of a light sensor interface 5, and two control inputs 6a and 6b for connecting a preferably digital control bus or control lines 7a and 7b, on.
The inputs 4a, 4b and the control inputs 6a and 6b are connected to a control device 8 of the electronic ballast 2.
To the light sensor interface 5 of the electronic ballast 2, an external resistor can be connected. In particular, a light sensor or photoresistor can be connected to the light sensor interface 5. Such a known light sensor (not shown) is designed to measure the brightness of the light incident thereon.
If a light sensor is actually connected to the sensor interface 5, then the brightness actual values of a region monitored by the light sensor can be supplied to the electronic ballast 2, wherein the control device 8 of the electronic ballast 2 then depends on the supplied Brightness actual values can dim the serving for illumination of the monitored area lamp.
As can be seen in FIG. 1, in the system 1, an analog or digital signal source is connected to the sensor interface 5 intended for receiving brightness values.
The passive sensor interface 5 is thus used to supply the electronic ballast 2 a generated by one or more signal sources 9 active input signal 3/10 Austrian Patent Office AT12 863U1 2013-01-15 via the inputs 4a, 4b.
The signal source 9 can provide either analog or digital signals, in the latter case, the electronic ballast 2 then in addition to the control inputs 6a, 6b has a second digital interface.
This second digital interface can be constructed as a DSI or preferably as a DALI or DMX interface. DSI (Digital Signal Interface), DALI (Digital Addresable Lighting Interface) and DMX (Digital Multiplex) are well-known control protocols for controlling or dimming digital photonic operating devices, e.g. electronic ballasts.
The digital DMX control protocol is also used in particular in the stage technology for the control of dimmers, intelligent headlamps and effect devices.
The signal source 9 can also provide analog signals, in which case preferably effect devices can be used. Such effect devices include i.a. Light organs, theatrical effects, fast running lights, as well as flash and flashing lights. Even simple sources, which are provided by means of static or user-adjustable setting, can be used as an analog signal source 9. Further examples of analog signal sources 9 are, in particular, signal generators which can generate signal shapes or modulate them with other signals.
Signal forms are generated or modulated by such signal generators such as sine, rectangle, triangle, pulses or other waveforms preferably having a wide frequency range.
Applications of such a system 1 with analog signal source 9 are diverse. Thus, e.g. an arrangement of three provided in the circle lighting systems 1 make the rotating field of a three-phase network visible.
As a signal source 9 can also be a vibration sensor, a microphone or a pressure sensor use. With the aid of a suitable amplifier, the lamp 3 can thus be controlled as a function of noise or of a pressure. Thus, a lighting alarm system is easy to implement.
The lighting system 1 can either have one or more light sources 3, which can also have different colors. Several lighting systems can also be combined.
If the electronic ballast 2 analog signals are supplied via the sensor interface 5, then various such signal sources 9 can be combined. It is also envisaged that only one analog signal source 9 control a plurality of electronic ballasts 2 with an active signal. When using, for example, a light organ or another effect device, a practically infinite number of effects can be achieved with a number of operating devices 2 which are equipped with different light sources.
As already mentioned, according to an alternative embodiment of the inventive lighting system 1, it is provided to connect a digital signal source 9 to the inputs 4a, 4b.
An optocoupler 10 may be provided between the sensor interface 5 and the signal source 9, for electrical isolation of the input and output circuits of the electronic ballast 2 and the signal source 9. Thus, the use of the opto-coupler 10 can provide potential separation between electronic ballast 2 and signal source 9 can be achieved, so that the signal lines from the signal source 9 to the sensor interface 5 can theoretically be arbitrarily long.
The optocoupler 10, however, should not be too far from the sensor interface 5, preferably a maximum of one meter of cable length and 50 cm distance from the electronic ballast see AT 2 863 U1 2013-01-15 Sensor interface 5.
The control terminals 6a, 6b are used to receive external digital control information according to, for example, a DALI, DSI or DMX system.
In a further embodiment, the electronic ballast 2 is configured such that via the control inputs 6a, 6b, a digital control signal either the normal sensor mode in which a passive device such as a light sensor is connected to the sensor interface 5, or the activate active mode, in the latter mode, an active signal from the analog or digital signal source 9 via the sensor interface 5 is transmitted.
By means of the control inputs 6a, 6b, the ballast 2 can therefore be supplied with either specific dimming setpoint values for the lamp 3 or a signal for activating or deactivating the passive or active mode. In the first case, the brightness of the lamp 3 is controlled in accordance with the dimming setpoints received via the control inputs 6a, 6b. In the passive or active mode, the brightness of the lamp 3 is controlled in accordance with the signal provided at the sensor interface 5.
In a system consisting of several ballasts 2 thus part of the ballasts can be controlled directly via dimming commands, while another part of the ballasts can participate in one controlled by a signal source 9 play of light.
Furthermore, it is provided according to a further embodiment, that the analog or digital active signal of the signal source 9 in the electronic ballast 2 of a filtering or change is supplied. This filtering is preferably performed by software, before the lamp 3 is controlled by the control device 8. The type of filtering and variation as well as various variable parameters of the filtering can then be determined via the control terminals 6a, 6b.
Fig. 2 shows another embodiment of a lighting system 1 'according to the present invention.
The inputs 4a, 4b of the sensor interface 5 are used here for the connection of a potentiometer 11. The use of the potentiometer 11 allows manual control or dimming of the lamp 3, since the brightness of the lamp 3 is controlled in dependence on the selected resistance of the potentiometer 11.
The brightness of the lamp 3 can thereby be changed significantly faster than with a light sensor. With a connected light sensor, the electronic ballast 2 performs a slow change in brightness.
By inserting the potentiometer 11, however, faster brightness changes can be performed by the electronic ballast 2, which can preferably be adapted to the reaction times of commercial dimmers.
In the embodiment of FIG. 2, the inputs 4a, 4b may be used to connect the potentiometer 11, this potentiometer 11 may allow, for example, a manual dimming as well as a switching on and off of the lamp 3. This embodiment can be used in existing lamp systems, in particular floor lamps, in which the existing sensor interface 5 is used to connect a potentiometer 11. Thus, a fast external light control can be realized in a simple manner.
Accordingly, the illumination system 1 'can optionally be equipped with a light sensor or with a potentiometer 11 in the passive mode, which is characterized by the connection of a passive electronic or optoelectronic component to the inputs 4a, 4b.
The electronic ballast 2 may e.g. recognize via a corresponding signal via the control inputs 6a, 6b or via the operation of a switch, if a light sensor or a potentiometer 11 is connected. However, the electronic ballast 2 can also automatically detect whether a potentiometer 11 is used for manual dimming or switching on / off.
First, the electronic ballast 2 causes a brightness change or dimming of the connected lamp 3, and at the same time checks whether the resistance value at the sensor interface 5 changes. When this resistance value changes, the electronic ballast 2 concludes that a photosensitive resistor is connected to the light sensor interface 5. On the other hand, if the resistance value does not change during the dimming, the electronic ballast 2 closes on a potentiometer 11 used for manual dimming. Depending on the result of this automatic detection, the light sensor mode or the potentiometer mode is activated.
According to the invention, two control inputs 6a, 6b are provided so that external control information can be supplied to the electronic ballast 2. Various types of control information may be received by the electronic ballast 2 via the control inputs 6a, 6b, among others. Configuration information, status query or brightness information.
Configuration information can provide the electronic ballast 2 information about what information about the inputs 4a, 4b are provided. This information can in particular activate the active or the passive mode, and thus determine whether the ballast 2 is supplied via the sensor interface 5, a signal of a passive device or an active transmitted signal.
The configuration information can also describe or define the passive or active mode in more detail, in which it can be stipulated, for example, that the connected passive component is a light sensor for light control, a potentiometer for light control or a resistor for addressing the electronic ballast 2 , For the use of a resistor for the purpose of addressing is expressly made to the document DE 103 29 090 A1. Of course, the connection of further components to the sensor interface 5 can also be communicated via this configuration information.
The control inputs 6a, 6b can also be used as a status query, so that the electronic ballast 2 can communicate via these control inputs 6a, 6b, for example, whether the passive or the active mode is activated, or in passive mode just a light sensor , a potentiometer 11 or a resistor is connected.
It is also possible to supply brightness information via the control inputs 6a, 6b. Thus, a parallel or additional input for the light control of the lamp 3 can be provided, which preferably can temporarily suspend the regulation via the light sensor or the brightness adjustment via potentiometer 11. The lamp 3 can then be switched on and off via the control inputs 6a, 6b in a simple manner.
Fig. 3 shows an electronic ballast 2 ', which can communicate wirelessly by means of a light modulation.
The electronic ballast 2 'contains a modulation unit 16 which modulates a signal 19 to be transmitted into corresponding control signals 20a, 20b for at least one lamp 3 or lamp arrangement. The control signals 20a, 20b can in particular turn the lamp 3 on and off or dim its brightness. Also conceivable are control signals 20a, 20b which determine the frequency or the color of the light emitted by the lamp 3 or by the lamp arrangement.
The modulation of the brightness and / or the frequency of the emitted light may be an already known analog or digital modulation.
Preferably, this light modulation is not or hardly recognizable to the human eye. If the brightness of the lamp is modulated by switching it on and off, it should be noted that the eye does not perceive the interruption of the illumination. For example, in the case of a signal transmission by modulation of the light frequency, frequencies in the invisible frequency range of the light spectrum, i. E. in the infrared and / or ultraviolet range.
To the electronic ballast 2 'is also a photo element 12 connected to receive a modulated light.
This information captured by the photoelement 12 in the form of brightness actual values or actual frequency values is supplied to the ballast 2 'via the sensor interface 5. A demodulation unit 17 then again demodulates this light information and extracts therefrom a useful signal 18 which corresponds to the previously transmitted signal 19.
The photoelement 12 shown in Fig. 3 is a passive receiver or a passive device in the form of, for example, a brightness-sensitive light sensor or a frequency-sensitive sensor such as e.g. IR sensor or UV sensor. For a passive receiver, it should be noted that a maximum line length and a maximum distance between the photoelement 12 and the ballast 2 'should not be exceeded.
In particular, this line length and distance should not be greater than one meter or 50 cm.
Alternatively, Fig. 4 shows an active photo-element 13, which is connected by an amplifier 14 and an optocoupler 15 to the sensor interface 5 of the electronic ballast 2 '. Thus, the line length from the photoelement 13 through the amplifier 14 to the optocoupler 15 may also be much greater than the maximum line length required by the passive photoelement 12 of FIG. Only the line length from the optocoupler 15 to the sensor interface 5 and the distance to the ballast 2 'are limited, preferably to one meter or 50 cm.
The signal 19 to be transmitted can be transmitted to the electronic ballast 2 ', for example, externally via the control inputs 6a, 6b. Alternatively, the useful signal 19 can also be obtained from the sensor interface 5, wherein in turn a passive signal of a passive component, such as e.g. a light sensor, or a signal of an active element of the sensor interface 5 is supplied.
The received signal 18 can be processed by the control unit of the ballast 2 ', stored, transmitted via the modulation unit and the lamp 3, or even forwarded digitally via the control inputs 6a, 6b.
An electronic ballast 2 'is thus suitable for transmitting a modulated signal by means of a modulation unit 16 and a lamp 3 or lamp arrangement, and to receive such a modulated signal by means of a photoelement 12 and a demodulation unit 17.
In a system comprising a plurality of electronic ballasts 2 ', it is necessary that a photo element 12 is connected to each serving as a receiver ballast 2'. Of course, a plurality of ballasts 2 'can also share a photoelement 12, in which the output signal of the photoelement 12 is forwarded to the sensor interface 5 of the corresponding ballasts 2'. It is advantageous in this case to connect an active photoelement 13, since the distance to the ballasts, as already seen, is not limited.
A system for illuminating a room comprising a plurality of ballasts 2 ', each with a lamp 3 and a photo element 12, 13 can use this communication method in which only one ballast detects the brightness of the room, and this brightness information to the other ballasts by light modulation transmitted. These other ballasts receive the brightness information on the respective photo element 12, 13, which serves as a communication receiver and not as a brightness meter. Thus, it can be ensured that, regardless of the calibration of the photo elements all lamps 3 can be controlled in the same room to the same brightness. 10.7
