Definitions

  • the invention relates to a central supply system for a large number of lights, in particular safety, rescue or emergency lights, which are connected at least via a light supply line to a voltage supply device that can be switched between mains voltage supply and emergency power supply and supplies at least one group of lights as part of the large number of lights.
  • a corresponding voltage supply device is, for example, a central battery system through which the various lights are connected to a mains voltage supply. If this mains voltage supply fails, the voltage supply device switches over to the emergency voltage supply.
  • Such an emergency power supply can work with alternating voltage as well as direct voltage.
  • the multiplicity of lights is usually connected in parallel to the corresponding light supply line, it also being possible for a plurality of such light supply lines with a corresponding multiplicity of lights to be connected to the voltage supply device. There is also the possibility that a corresponding switchover takes place separately for each individual light supply line with a large number of lights.
  • a corresponding central supply system can 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 the corresponding safety, escape sign or emergency luminaires, should have a reduced luminous flux, ie a reduced lighting level. For the normal lighting of such rooms, this means that it is completely switched off or at least dimmed to a very low lighting level.
  • EP 0 534 793 A1 describes an emergency lighting device with an emergency ballast and an HF ballast. These are connected to a battery or to a general power supply. A switching network is arranged between the two power supplies. Also shown is a ballast control circuit that controls the RF ballast. The circuit is connected to a dimmer switch via a line. This means that with this citation there is no possibility of dimming the corresponding lamp via the emergency ballast when it is in operation.
  • a certain dimming level can be set individually for each lamp in the event of an emergency power supply using a rotary switch or a so-called dip switch.
  • the corresponding dimming level and its setting via the corresponding switch are no longer taken into account, and these luminaires are switched back to their corresponding nominal luminous flux for normal mains operation.
  • each lamp has to be opened to modify the dimming level and little flexibility is possible for varying the dimming level.
  • the present invention is therefore based on the object of improving a central supply system or a corresponding method for dimming a large number of lamps in such a way that more flexible dimming is possible in a simple manner and without great effort.
  • the voltage supply device has a dimming control for the lighting group.
  • the lights namely all lights of the corresponding lighting group, can be dimmed directly on the light without any further settings.
  • Any luminaire-specific dimming devices that may be present are not influenced by this essentially central dimming control and can optionally be used additionally.
  • 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.
  • the dimming control can be assigned to both the mains voltage supply and the emergency voltage supply. This can be of advantage if the emergency power supply is also an AC voltage.
  • the mains voltage supply is usually an alternating voltage.
  • the dimming control for program control is connected to each voltage regulator of a luminaire of a luminaire group at least for brightness control or luminous flux control.
  • corresponding data are transmitted to the voltage regulator of a lamp via the lamp supply line or a separate data line, which then causes the dimming on site, but through central control.
  • the dimming is essentially software-controlled.
  • the corresponding dimming control can take place, for example, via an input mask on a screen in which the dimming can be set for a lighting group or also for several lighting groups. After the appropriate setting, communication then takes place with the corresponding voltage regulators in order to influence them so that the associated lights are dimmed.
  • Such a use of a voltage regulator can be considered to be advantageous in particular if the lamp has at least one LED as a light source.
  • LEDs have, for example, a voltage regulator or a lamp driver, which is controlled by corresponding data from the central dimming control in order to dim the LED.
  • incandescent lamps fluorescent lamps, energy-saving lamps, low or high-voltage halogen lamps or metal halide lamps can also be used as lighting means.
  • dimming control in which, for example, the transmission of data for dimming can be dispensed with, is a dimming control which is designed as a phase control. This also applies analogously to a dimming control that is designed as a phase control.
  • phase control a corresponding luminaire is initially de-energized after a network zero crossing. After a predetermined and adjustable time has elapsed, a triac in the dimming control is ignited, for example, which switches on the mains voltage supply.
  • phase shift in such a phase control which can occur between voltage and current in transformers as part of the luminaires, for example, current and voltage or the corresponding zero crossings can also be measured. This allows such a phase shift to be recognized and the time of the ignition pulse can be adjusted accordingly.
  • phase control In the case of phase control, the mains voltage supply is switched on directly at the zero crossing and switched off again after a predetermined and adjustable time has elapsed.
  • phase control can for example have a MOS-FET as a switch.
  • the electronic control gear assigned to the luminaires must be selected in such a way that they have the property of processing a supply voltage modified by phase control or phase control for output power control.
  • Modern control ICs in the operating devices have recently made this possible and thereby allow dimming operation on such phase-angle or phase-cut controls.
  • this can be connected downstream between the light supply line and a voltage switching device for switching between the mains and emergency power supply.
  • the light 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 light supply line.
  • the luminaire can have an electronic or electrical ballast and / or a luminaire driver. These are addressed by the data from the dimming control and ensure appropriate dimming, which is controlled centrally for lights in at least one lighting group.
  • the lamp can be addressable, for example, the address being set or assigned on the lamp or also centrally by the central supply system.
  • the dimming control can be part of a light management system and accordingly integrated in it.
  • a light management system is, for example, DALI, through which the light can be controlled with all the DALI components involved and each corresponding component can be addressed individually. This also applies in particular to the ballasts or the lamp drivers mentioned above.
  • 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, corresponding programming is also possible for dimming using the corresponding dimming control.
  • each individual light can be switched between at least two lighting levels.
  • a corresponding luminous flux is influenced by the voltage supply device 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 influencing of the luminous flux results from controlling the time-averaged current that flows through the corresponding lights.
  • program-controlled influencing can also take place.
  • a luminaire's own dimming circuit is used for this purpose, which can be addressed and controlled, for example, by the dimming control of the voltage supply device using appropriate commands.
  • the luminaire's own dimming circuit can, for example, be part of a corresponding luminaire driver or a ballast.
  • the invention it is possible to centrally dim a large number of lights and in particular safety, escape sign or emergency lights in essentially every lighting situation of the general lighting and in particular in emergency situations, this dimming being carried out in groups for such lights or for all of these lights.
  • this dimming being carried out in groups for such lights or for all of these lights.
  • several groups of lights for example in different cinemas or the like, can be dimmed centrally and in different ways and at different times compared to one another. This is done in the same way as with only one lighting group.
  • FIG Figure 1 shows a schematic diagram of a central supply system 1 according to the invention. From this central supply system 1, at least one voltage supply device 4 and a number of lights 2 connected to it via a light supply line 3 are shown. To Figure 1 only three lights are shown, this being only an example and, as a rule, a large number of such lights are connected to the corresponding voltage supply device 4 via the light supply line 3. Some of the lights can form a group of lights 7 which can be dimmed centrally and in a uniform manner. Further parts of the central supply system, such as a central controller or the like, are shown in FIG Figure 1 not shown. In this case, however, there is the possibility that such a central control device controls a plurality of voltage supply devices 4 and each of these voltage supply devices 4 controls a plurality of lighting groups 7 in a corresponding manner.
  • a central control device controls a plurality of voltage supply devices 4 and each of these voltage supply devices 4 controls a plurality of lighting groups 7 in a corresponding manner.
  • the voltage supply device 4 is connected to a mains voltage supply 5 for normal operation and additionally to an emergency voltage supply 6 for emergency operation.
  • the mains voltage supply 5 is an alternating voltage
  • the emergency voltage supply 6 can be both an alternating voltage and a direct voltage, which in the latter case is for example a battery system can be supplied.
  • a corresponding voltage supply device 4 is also called a central or group battery system.
  • the light supply line 3 consists of two individual lines, with one or two data lines additionally being able to be provided. According to the invention, however, the data is usually transmitted via the lamp supply lines 3, so that no separate data lines are necessary.
  • the corresponding lights 2 are connected in parallel with the light supply line 3, each light having at least one corresponding light source 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 can have an electronic ballast 12, a voltage regulator 9 or a lamp 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 carried out by a dimming control 8, see also Figures 2 and 3 in the voltage supply device 4.
  • the dimming control 8 can be designed in different ways.
  • FIG. 2 shows an example of a dimming control 8 in the form of a phase control 10. This is arranged between a voltage switching device 11 of the voltage supply device 4 and the mains voltage supply 5.
  • the corresponding dimming control 8 is also designed as a phase control 10, but is arranged downstream of the voltage switchover device 11, ie arranged between it and the light supply line 3, see also Figure 1 .
  • the corresponding voltage switching device 11 can be designed as a relay or as an electronic switching device and is known per se.
  • the voltage switching device 11 is used to switch between the mains voltage supply and the emergency voltage supply.
  • the dimming control is assigned to the voltage supply device 4, so that all the lights in a light group or also different light groups can be dimmed centrally from this.
  • the consumer will initially remain de-energized after a network zero crossing. After a predetermined and adjustable time has elapsed, a triac in the dimmer, for example, is then ignited in order to switch on the voltage supply. In the next zero crossing, the triac drops below a holding current and the supply voltage is switched off again.
  • inductive loads are also supplied by the voltage supply device 4, there is usually a phase shift between voltage and current. This can lead to the triac outputting 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 provide a corresponding one Detect phase shift and adjust the timing of the ignition pulse accordingly.
  • phase control takes place, the mains supply voltage switches on directly at the zero crossing and switches off again after a specified and adjustable time has elapsed.
  • a MOS-FET for example, can be used as a corresponding switch. For this switch, however, the mains voltage would first have to be rectified, for example via a bridge rectifier.
  • this can 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 corresponding component is addressed individually.
  • a corresponding dimming can also take place under program or software control, in that the dimming control transmits corresponding data to devices of the luminaire, such devices being, for example, voltage regulators 9, electronic ballast 12 or luminaire drivers 13, see Figure 1 .
  • the corresponding dimming takes place only with mains voltage supply
  • dimming can take place not only with mains power supply, but also with emergency power supply. This is especially true when the emergency power supply is an AC voltage.
  • the dimming can take place not only to dim lights in operationally darkened rooms, such as cinemas, theaters or the like, but also to reduce the inrush current. This is done, for example, in that when a lamp is switched on, a corresponding dimming is specified, for example with a soft start, by which the inrush current is reduced in order, for example, to avoid welding of contacts or the like when switched on due to excessive inrush currents.
  • this is also done centrally for at least all lights of a light group.
  • a corresponding dimming especially in operationally darkened rooms, takes place, for example, in such a way that the luminous flux is 100% in emergency operation, while it is 30% in mains operation. Dimming to 30% can also be used, for example, when switching on the corresponding lights to reduce the inrush current.
  • the lights can also have address switches, DIP switches or other components.
  • the central dimming there is also an individual dimming of each lamp, which can be particularly advantageous for different lighting means.
  • the central dimming takes place as described above, while the individual dimming can be carried out in software by transmitting appropriate data to components of each luminaire, such as voltage regulator, ballast, luminaire driver or the like.
  • each voltage switching device of the voltage supply device is assigned a dimming control in order to dim the corresponding lighting group (s) centrally. This makes it possible to dim all connected lights at the same time and in the same way without any further modifications on the light side.
  • dimming can also be used during the start phase when the lights are switched on in order to avoid excessive inrush currents.
