Description

The invention relates to a lamp, in particular for emergency light supply, with a Illuminant and an electronic ballast (EVG) assigned to it, which has at least one connection for light control and a supply connection for the voltage supply of the illuminant, the connections with a corresponding control system or corresponding power supply lines are connectable.

As illuminants for such a lamp come because of favorable electrical characteristics often fluorescent lamps are used. The corresponding is used to feed them electronic ballast. Such lights that are part of a common building lighting management system may have, in the case of their use as part of a Emergency lighting supply has certain properties, such as an automatic Enable function monitoring. Such function monitoring includes control and maintenance work through functional tests and duration tests.

In order to be able to carry out such automatic function monitoring so far, specially developed electronic ballasts or separate monitoring modules in the Luminaires used that function monitoring without additional data or control lines enabled.

However, there is a very large number of possible ECG - lamp combinations, for which special ballasts cannot always be developed. Farther it has been found that some ECGs do not have certain functions such as the reduction in luminous flux required in emergency lighting DC operation.

There are light management systems known from practice where dimming is used the lighting is possible during mains operation. However, when using these lights as part of an emergency light supply, operating conditions occur during the The lighting and battery configuration of the light management systems is not taken into account can be.

The invention is therefore based on the object of a lamp of the type mentioned Art to improve in such a way that especially when using electronic ballasts with Light control connection an extended functionality of the lights with simple technical Medium and for a variety of lights is given.

This task is performed on the lamp with the features of the preamble of the claim 1 solved in that the connections of the electronic ballast (EVG) a separate monitoring device is arranged which inputs and outputs for each has a control system and power supply and at least one control unit, which is at least data about the control system and / or the power supply line transmitted.

Due to the separate monitoring device, each luminaire receives the corresponding Control system signals received via associated inputs and via corresponding Outputs sent to the ECG for its control. Furthermore, the Monitoring device also connected upstream of the electronic ballast in the power supply, so that corresponding influences on the power supply in particular emergency light supply are possible. The monitoring device can be used with various ECGs with light control connection are used, with an extended functionality is given by the monitoring device and its control unit. through The control unit contains data such as that used in particular for automatic function monitoring are necessary in the case of an emergency light supply, between luminaire and one appropriate control transferable. This is done by the monitoring device a corresponding control of the lamp via the ECG in the event of an emergency light supply as well as data exchange regardless of the actual structure of the EVG.

This means that a large number of possible ECG lamp combinations are available together with a corresponding monitoring device, in particular for emergency light supply usable.

To the monitoring devices in a simple manner in or on the lamp To install the luminaire, the monitoring device can act as a monitoring and control module be trained. This is prefabricated and can be used with the corresponding Luminaires can be retrofitted.

To make it easy to set up the control unit and use commercially available components To be able to, the monitoring device as a control unit, a microprocessor exhibit.

The control connections of the ECGs can accept various control signals. On An example is an analog control signal, so that the ECG can be controlled analog. Such one Control signal is based, for example, on the 1 ... 10V system, which is relatively widespread and allows analog control of the ECGs. Advantages of the 1 ... 10V system is the simple application and its flexibility. The TOE have Corresponding 1 ... 10V interfaces, which are designed as potential-free control inputs are. The dimming range is between 1 and 100% with a linear characteristic.

Corresponding to the 1 ... 10V system, the monitoring unit also has in this connection via appropriate interfaces at the entrance and exit for light control.

In order to be able to control the illuminant in the event of an emergency light supply by the monitoring device, the monitoring device can have a current variation device for connection to the light control connection of the electronic ballast, a separating device separating a connection between light control connection and control system and establishing a connection between light control connection and a safety light management system via the voltage supply ,
The safety light management system provides the corresponding emergency light supply, for example by switching some lights of general lighting in a building to single or group battery systems for direct voltage supply in the event of a failure of the usual supply voltage. The current variation device can, however, be designed in different ways, such as, for example, as an electronic potentiometer, as a programmable current sink, or as a coding switch with fixed resistors. The current variation device is used to load the control connection of the ECG in order to set a corresponding luminous flux ratio in the event of an emergency light supply. Even with only one luminous flux ratio permitted by the electronic ballast, the current variation device can influence the electronic ballast accordingly, if this is necessary for the emergency light supply.

In this context, the separation device is used for all-pole separation of the Control system from the control connection of the ECG to influence the luminaire Allow emergency light supply through the corresponding emergency light supply system.

A corresponding separation device can, for example, be one of the control device switchable relay device be formed. This connects the current variation device with the light control connection of the ECG with simultaneous disconnection the light control connection from the control system.

In addition to using a current variation device, there is also the option of after disconnecting the lighting control connection of the ECG from the control system directly from the control unit of the monitoring device via a corresponding interface device Data via the light control connection to the ECG for its control to transmit. In this case, the control of the ECG is carried out analogously to the control the tax system.

In order to control the monitoring unit in this context, monitoring or diagnostic data via the voltage supply lines and / or the Control system can be transmitted to the monitoring device and to its control unit. This ensures that complete function monitoring the corresponding luminaire or its control for emergency light supply is possible.

It can prove advantageous if the control system as a bus system with predetermined Protocol is formed. In this way, corresponding data is sent to the ECG can be transmitted via the monitoring device.

A protocol has recently been with all manufacturers of lighting systems and the like enforced in this context, this protocol as the DALI protocol is designated (DALI = Digital Addressable Lighting Interface.) Note that such DALI systems also with a two-wire line and without a bus system can be trained. A corresponding DALI control unit manages after the master-slave principle the communication flow and the access of all components on the two-wire data line. With such a DALI system, the Address ballasts individually and usually up to 16 freely definable Groups and up to 16 light scenes possible. This means that each ECG can do it individually addressed by the control unit and with up to 16 different light values for the light scenes are programmed.

If a bus system is used instead of a two-wire line, the increase continues the functionality of the overall system with increased options for variable addressing a higher number of ECGs with even more programming options the single ECG.

To easily identify an error for a single lamp and the associated one To be able to carry out lamps, the ECG can draw a current corresponding lamp from the control unit, in particular by means of a resistance device be monitorable. If the ECG / lamp combination is intact the current consumed by the ECG has a certain limit. The loading device then generates a short current pulse as an additional load the supply line, which then e.g. centrally in the safety light management system can be evaluated. In the event of a lamp fault or defective ECG the current has a certain limit and this additional load does not occur.

There is also the possibility of error and / or test and / or control information to transmit through the tax system. This is already the case with the one above addressed DALI protocol in the case of error information possible that an error bit contained in the protocol is evaluated.

Both the 1 ... 10V and DALI systems still have the option of by transmitting certain control information via the monitoring device and a specific one by means of the associated control device of the corresponding lamp Luminous flux ratio to communicate e.g. the battery discharge current for emergency lighting to reduce to a permissible, standardized minimum. Besides, can the evaluation and processing of the data by the control unit as part of the monitoring device take place, with a corresponding forwarding of the data to For example, a central automatic light management system or an emergency light management system is possible.

To easily assign a corresponding address to each luminaire on site can, an addressing device can be assigned to each control unit. This can Both on-site and centrally adjustable from the corresponding management system his.

In connection with the DALI system it should be noted that the electronic ballast can be controlled digitally can be.

A separation from the DALI system can be dispensed with in some cases, if a property of DALI - ECG is used, that on the preprogramming a fixed luminous flux ratio for DC operation. In this case it is advantageous if the monitoring device is connected to the supply connection has connectable DC voltage source. Will this with the supply connection connected, the corresponding luminous flux ratio is set. In particular is such a switchover to the factory-programmed luminous flux ratio then possible and effective if one or two of the three mains phases of the power supply fail and only the feeding phase is still available. At the applicable ones In this case, standards are all operated in a standby mode Turn on lights.

In order not to use a separate DC voltage source, this can be considered as between Interconnectable supply voltage lines and supply connection Rectifier device can be formed.

A simple switchover to the rectifier device can be achieved by that a switchover device, in particular switchable by the control unit between rectifier device and supply voltage lines on the one hand and Supply connection is arranged on the other hand.

In order to continue to enable the switching possibility of each ECG, one in particular Interrupt switch device which can be actuated by the control unit in at least a supply voltage line arranged in the monitoring device his.

Overall, according to the invention there is a combined operation of lights, which also Are part of general lighting and from a light management system can be controlled as part of the safety lighting including the monitoring function as well as the lowering of the luminous flux for more efficient battery utilization, whereby all commercially available fluorescent lamps are used as illuminants with suitable electronic ballasts if they can also be a control connection for light management systems to influence the luminous flux.

In the following, advantageous exemplary embodiments of the invention are described on the basis of the Drawing attached figures explained in more detail.

In Figure 1 is a schematic representation of a first embodiment of an inventive Light 1 shown. In this embodiment as well as in the further exemplary embodiments, the luminaire 1 is part of a building lighting system, a plurality of such lights 1 with a light management system 26 interconnected to control the individual lights and to set light scenes are. Luminaires 1 can be grouped in one room or in several Rooms of the building.

Furthermore, the luminaire 1 is also provided with a safety light management system 20 interconnects that with an emergency light supply at least some lights 1 of the building lighting system operated accordingly as emergency lights. In addition, more Safety and emergency lights controlled by the safety management system 20.

The lamp 1 has a monitoring and control module as the monitoring device 8 12 on. This is between an electronic ballast 3 with an associated Illuminant 2 and the corresponding supply lines from the light management system 26 and safety light management system 20 interconnected. Corresponding the monitoring device 8 has inputs 9 for a light management system 26 comprehensive control system 6. Corresponding outputs 15 of the monitoring device 8 are the electronic ballast EVG 3 and its light control connection 4 assigned. In addition, the monitoring device 8 also has inputs 10 and outputs 16 for the voltage supply. The inputs 10 are included connected to a corresponding voltage source, which in the case of the light management system 26 usually an AC voltage supply and in the case of the safety light management system 20 is usually a DC voltage source. at Normal operation of the illuminants 2 takes place from the AC voltage source and in the case of an emergency light supply, if the AC voltage source fails is supplied by the DC voltage source. Such DC voltage source can be used, for example, as an accumulator or battery device be executed. This can be arranged both centrally and decentrally.

The monitoring device 8 has a microprocessor 13 as the control unit 11, the control lines 32 shown with dotted lines with various switching devices and in particular the separating device 19 and the interrupter device 31 are connected is. Furthermore, the microprocessor 13 is connected to an addressing device 27. An address can be assigned to each lamp 1 by means of this. Finally, the microprocessor 13 still with a current variation device 18, for example in the form of a electronic potentiometer 21 connected. This can be done via a relay device 22 can be connected to the light control connection 4 of the electronic ballast 3 as a separation device 19. The relay device 22 switches between a connection to the current variation device 18 and the control inputs 9 for connection to the control system 6 back and forth forth, being controlled by the microprocessor 13.

Finally, the microprocessor 13 is also equipped with a resistance device 25 for acceptance a voltage drop across the resistor device.

The power supply takes place via power supply lines 7, which go to the inputs 10 of the monitoring device 8 and through it to exits 16 extend. The outputs 16 are with a corresponding supply connection 5 of the ECG connectable.

The resistance device 25 is used when switching on the ECG or in operation to detect flowing current that exceeds a certain limit. The loading device 32 then generates a short current pulse as an additional load on the supply line 10, which then e.g. centrally in the safety light management system 20 can be evaluated. Such a current pulse is missing in the event of a lamp fault or a defective ECG, this is interpreted as an error.

The control system 6 is in the embodiment in Figure 1 as a 1 ... 10V control system 14 formed, with inputs 9 and outputs 15, as well as light control connection 4 are designed as corresponding 1 ... 10 V interfaces 17. To do that Illuminants 2 can no longer be influenced by the light management system 26, but through the safety light management system 20, the microprocessor 13 controls the electric potentiometer 21 on and at the same time by controlling the microprocessor 13 actuates the relay device 22 so that the control connection 4 from Control system 6 is separate and connected to the electronic potentiometer 21: In such a position of the relay device 22, the lamp 2 can now EVG 3 are controlled by the safety light management system 20.

As an alternative to the electronic potentiometer 21, so-called programmable ones can also be used Current sinks or a combination of a coding switch with fixed resistors be used. The corresponding current variation device 18 is used each for the corresponding load on the light control connection 4.

Figure 2 shows a second embodiment of a lamp 1 according to the invention. This differs from the exemplary embodiment according to FIG. 1 in particular in that the electronic ballast 3 is digitally controllable and instead of the current variation device 18, for example in the form of an electronic potentiometer 21, an interface device 23 is used. That means when the light control connection is disconnected 4 from the control system 6, see Figure 1, and connection to the interface device 23, a data stream is transmitted directly from the microprocessor 13 to the ECG in order to achieve the desired luminous flux ratio in AC and DC operation define. In this case too, the luminous flux ratio is controlled not through the general light management system 26, but through safety light management 20 The interface device 23 can be a DALI interface be working with the appropriate DALI protocol. DALI is an interface standard the lighting industry (DALI - Digital Adressable Lighting Interface), the a uniform interface definition for the function of a DALI ECG or one DALI-compliant consumer sets in an illuminated system and the interchangeability the TOE from different manufacturers. The DALI control system can be designed as both a two-wire and a bus system.

In connection with the resistance device 25 it should also be noted that at missing current pulse, i.e. in the event of a lamp fault or defective ECG, see the above explanations, a corresponding error due to an error bit in the DALI protocol can be transferred.

FIG. 3 shows a third exemplary embodiment of the luminaire 1 according to the invention. In this exemplary embodiment, a digitally controllable electronic ballast 3 is also used DALI system used, the corresponding lines of the control system 6 as Bus system 24 are formed.

This embodiment differs from the previous ones in particular in that a separation of the light control connection 4 from the control system 6, see Figure 1, not done. Instead, a special property of DALI - EVG 3 exploited. This property applies to a fixed preset luminous flux ratio for DC operation of the electronic ballast 3. In this case, the monitoring device 8 has a DC voltage source 8 in the form of a rectifier device 29 which is connected to the external AC voltage source is connected via the inputs 10, see also the previous statements. Influenced by the safety light management system 20, switches the microprocessor 13 by means of switching device 30, for example Form a relay, the rectifier device 29 in the voltage supply lines 7, so that the supply connections 5 of the electronic ballast 3 are supplied with direct voltage become. In this way, the factory-programmed luminous flux ratio of the TOE 3 can be switched if one or two of the three network phases of the Supply voltage fail and the feeding phase is still available. For one In such a case, it is mandatory to operate all in the standby mode Switch on lights 1, whereby a separation from the DALI bus system 24 is not necessary is.

It should also be noted that with a DALI ECG 3, an error evaluation can also be carried out via the bus system 24 can take place since an error bit is contained in the DALI protocol. On an evaluation of the current consumption of the electronic ballast 3 via resistance device 25 can then be dispensed with.
