Definitions

  • the invention relates to a central supply system for a plurality of lights, especially safety, rescue or emergency lights, which are connected at least via a lamp supply line with a switchable between mains voltage and emergency power and at least one lighting group as part of the plurality of lights supplying power supply device.
  • a corresponding power supply device is, for example, a central battery system, by which the various lamps are connected to a mains voltage supply. If this mains voltage supply fails, switching to emergency power supply takes place by means of the voltage supply device.
  • Such emergency power supply can work with both AC and DC voltage.
  • the plurality of lights is usually connected in parallel with the corresponding lamp supply line, with several such light supply lines with a corresponding plurality of lights can be connected to the power supply device. In this case, there is still the possibility that for each individual lamp supply line with a plurality of lights, a corresponding switching takes place separately.
  • a corresponding central supply system can, in addition to the voltage supply device, also have a central controller which monitors and controls a plurality of such voltage supply devices.
  • corresponding lights are arranged in operationally darkened rooms, see for example cinemas, theaters or the like. If a demonstration takes place in these darkened rooms, all luminaires, including corresponding safety, emergency or emergency luminaires, should have a reduced luminous flux, ie a reduced level of illumination. For the normal illumination of such rooms, this means that it is completely switched off or at least dimmed to a very low level of illumination.
  • a disadvantage of the previously known central supply systems is that each luminaire must be opened to modify the dimming level and little flexibility is possible for varying the dimming levels.
  • the present invention is therefore based on the object to improve a central supply system or a corresponding method for dimming a plurality of lights to the effect that a more flexible dimming in a simple manner and without much effort is possible.
  • the voltage supply device has a dimming control for the lighting group.
  • the luminaires namely all the luminaires of the corresponding luminaire group, can be dimmed directly and simultaneously directly to the luminaire without any further adjustment.
  • the dimming control according to the invention can dim all lights of the corresponding lighting group at the same time and in the same way.
  • this can be assigned to the mains voltage supply.
  • the dimming control is assigned to both the mains voltage supply and the emergency power supply.
  • the emergency power supply is also an AC voltage.
  • the mains voltage supply is usually an AC voltage.
  • the dimming control for program control is connected to each voltage regulator of a luminaire of a lighting group at least for brightness control or luminous flux control.
  • corresponding data is transmitted to the voltage regulator of a luminaire via the luminaire supply line or a separate data line, which then effects the dimming locally, but through central control. That is, in this case, the dimming is essentially software-controlled.
  • the corresponding dimming control can take place, for example, via an input mask of a screen in which the dimming can be set for one lighting group or even several lighting groups. After appropriate adjustment, communication with the corresponding voltage regulators takes place in order to influence them so that the associated lights are dimmed.
  • Such a use of a voltage regulator can be considered particularly advantageous if the luminaire has at least one LED as the luminous means.
  • LEDs include, for example, a voltage regulator or a light driver controlled by appropriate data from the central dimming controller to dim the LED.
  • LEDs as bulbs incandescent lamps, fluorescent lamps, energy-saving lamps, low or high-voltage halogen lamps or metal halide lamps are used.
  • dimming control in which, for example, can be dispensed with a transmission of data for dimming, is a dimming control, which is designed as a phase control. This also applies analogously to a dimming control which is designed as phase-segment control.
  • a corresponding luminaire is initially de-energized after a line zero crossing. After a predetermined and adjustable time, for example, a present in the dimming control triac is ignited, which turns on the mains voltage supply.
  • phase shift in such a phase control which can occur, for example, in transformers as part of the lights between voltage and current
  • in addition can be done measuring current and voltage or the corresponding zero crossings. As a result, such a phase shift can be seen and the timing of the ignition pulse can be adjusted accordingly.
  • phase control section the mains voltage supply is switched on directly in the zero crossing and switched off again after a predetermined and adjustable time.
  • a phase section control can have, for example as a switch, a MOS-FET.
  • the electronic operating devices associated with the luminaires are to be selected such that they have the property of processing a phase-angle or phase-section-modified supply voltage for the output power control.
  • Modern control IC in the control gear allow this recently and thereby allow the dimming operation on such phase control or phase control.
  • the dimmer control can be connected between a voltage switching device for switching between mains and emergency power supply of the voltage supply device and the mains voltage supply.
  • a voltage switching device for switching between mains and emergency power supply in the form of an alternating current.
  • the luminaire supply line can also be designed for data communication, so that, in addition to voltage, data can also be transmitted via, for example, two individual lines of the luminaire supply line.
  • the lamp may have an electronic or electrical ballast and / or a light driver. These are addressed by the data of the dimming control and ensure a corresponding dimming, which is centrally controlled for luminaires of at least one lighting group.
  • the luminaire can be addressable, for example, wherein the address can be set or assigned to the luminaire or else centrally by the central supply system.
  • the dimming control can be part of a light management system and integrated accordingly in this.
  • a light management system is, for example DALI, controlled by the light with all DALI components involved and each corresponding component is individually addressable. This applies in particular to the ballasts or the above-mentioned lamp drivers.
  • DALI is not only suitable for use in individual rooms, but can also be integrated into the central supply system of a higher-level building management system. In particular, with DALI, a corresponding programming is also possible for dimming by means of the corresponding dimming control.
  • a simultaneous dimming of a variety of switchable with a between mains voltage and emergency power supply and at least a lighting group of the plurality of lamps supplying power supply device connected lights each individual lamp is switchable at least between two lighting levels.
  • the dimming for all luminaires between a maximum and a minimum level of illumination, wherein the minimum level of illumination can correspond to switching off the luminaire.
  • a corresponding luminous flux is influenced by means of the dimming control, at least during the mains voltage supply.
  • the influencing of the luminous flux for dimming can be done by phase control or phase control.
  • the corresponding influence of the luminous flux results by controlling the time-averaged current flowing through the corresponding lights.
  • Phasenanites- or phase control section can also be a program-controlled influence.
  • a dimming control is also used when starting or switching on the corresponding lamps.
  • a corresponding inrush current can be reduced, which otherwise could lead, for example, to a welding of switch contacts or the like as well as to the destruction or damage of a corresponding luminous means.
  • an individual dimming in addition to the central dimming.
  • This purpose is a light-dedicated dimming circuit, which can be addressed and controlled for example by the dimming control of the power supply device by appropriate commands.
  • the light-emitting dimming circuit may for example be part of a corresponding light driver or a ballast.
  • FIG. 1 shows a schematic diagram of a central supply system 1 according to the invention. From this central supply system 1, at least one power supply device 4 and a number of connected thereto via a lamp supply line 3 lights 2 are shown. To FIG. 1 only three lights are shown, this is only an example and usually a plurality of such lights are connected to the corresponding power supply device 4 via the lamp supply line 3. Some of the luminaires can form a luminaire group 7, which can be dimmed centrally and in a uniform manner. Other parts of the central supply system, such as a central controller or the like, are for simplicity in FIG FIG. 1 not shown. However, there is the possibility that such a central control device controls a plurality of power supply devices 4 and each of these power supply devices 4 a plurality of lighting groups 7 in a corresponding manner.
  • the power supply device 4 is connected to the normal operation with a mains voltage supply 5 and additionally for an emergency operation with an emergency power supply 6.
  • the mains voltage supply 5 is an AC voltage
  • the emergency power supply 6 may be both an AC voltage, as well as a DC voltage, which in the latter case, for example a battery system can be delivered.
  • a corresponding voltage supply device 4 is also called a central or group battery system.
  • the luminaire supply line 3 consists in the illustrated embodiment of two individual lines, wherein optionally one or two data lines can be additionally provided. According to the invention, however, as a rule the data transmission takes place via the luminaire supply lines 3, so that no separate data lines are necessary.
  • each lamp 2 has at least one corresponding lamp such as LED, incandescent lamp, fluorescent lamp, low or high voltage halogen lamp, energy saving lamp, metal halide lamp or the like. Furthermore, such a lamp may have an electronic ballast 12, a voltage regulator 9 or a light driver 13. Corresponding light drivers are used, for example, in LEDs, which are nowadays, for example, switched-mode drivers.
  • a corresponding dimming of at least all lights of a lighting group 7 is done by a dimming control 8, see also FIGS. 2 and 3 in the power supply device 4.
  • the dimming control 8 can be designed in different ways.
  • FIG. 2 shows a first embodiment of such a dimming control 8 in the form of a phase angle control 10. This is arranged between a voltage switching device 11 of the voltage supply device 4 and the mains voltage supply 5.
  • FIG. 3 is the corresponding dimming control 8 also designed as a phase control 10, but downstream of the voltage switching device 11, that is arranged between this and the lamp supply line 3, see also FIG. 1 ,
  • the corresponding voltage switching device 11 may be formed as a relay or as an electronic switching device and is known per se.
  • the voltage switching device 11 is used for switching between mains voltage supply and emergency power supply.
  • the dimming control of the power supply device 4 is assigned, so that from this central all lights of a lighting group or different lighting groups are dimmable.
  • the load will remain de-energized after a line break.
  • a predetermined and adjustable time is then ignited, for example, a triac in the dimmer so as to turn on the power supply. In the following zero crossing, a holding current of the triac is exceeded and the supply voltage is switched off again.
  • a phase shift between voltage and current usually sets in. This may cause the triac to output an ignition pulse, for example, before the current has actually become zero. This can be prevented by measuring the current and voltage to determine the zero crossings, so as to obtain a corresponding one Detect phase shift and adjust the timing of the ignition pulse accordingly.
  • the mains supply voltage switches on directly at the zero crossing and switches off again after a preset and adjustable time.
  • a corresponding switch for example, a MOS-FET can be used.
  • the mains voltage would first need to be rectified, for example, via a buckle rectifier.
  • this may be part of a light management system, such a light management system being able to work with DALI, for example.
  • a light management system controls the light with all the DALI components involved and each component is individually addressed.
  • a corresponding dimming can also be program or software controlled by the dimming control transmits corresponding data to facilities of the lamp, such devices are, for example, voltage regulator 9, electronic ballast 12 or light driver 13, see FIG. 1 ,
  • the corresponding dimming is only at mains voltage supply, while in the embodiment according to FIG. 3 Dimming can be done not only with mains voltage supply, but also with emergency power supply. This is especially true when the emergency power supply is an AC voltage.
  • the dimming according to the invention can be done not only for dimming lights in operationally darkened rooms, such as cinemas, theaters or the like, but also to reduce the inrush current. This is done, for example, by the fact that upon switching on a lamp, a corresponding dimming, for example with a soft start, is specified, by which the inrush current is reduced, for example, to avoid welding of contacts or the like when switched on by high inrush currents.
  • a corresponding dimming especially in operationally darkened rooms, for example, in such a way that in emergency mode, the luminous flux is 100%, while it is 30% in network operation. Dimming to 30% can also be used, for example, when switching on the corresponding luminaires to reduce the inrush current.
  • the luminaires may also have address switches, dip switches or other components.
  • the central dimming additionally an individual dimming of each lamp takes place, which may be particularly advantageous for different light sources.
  • the central dimming is carried out as described above, while the individual dimming software can be done by transmitting appropriate data to components of each lamp, such as voltage regulator, ballast, lamp driver or the like.
  • each voltage changeover device of the voltage supply device is assigned a dimming control in order to centrally dim the corresponding lighting group (s). This makes it possible to dim all connected luminaires at one time and in the same way without further modifications on the luminaire side.
  • the dimming can also be used during the start-up phase when the lights are switched on in order to avoid excessive inrush currents.
