Abstract

The illumination system has a number of lights (2) and a control/monitoring device (3) connected to the lights via data lines (4-7), whereby each light has an associated address code and a memory device for electronic storage of a unique address code that can be read out over the data line for light identification by the control/monitoring device.

Description

The invention relates to a lighting system, in particular for emergency lighting, with a plurality of lights and at least one control / monitoring device, which with the lights over at least one data line is connected, each lamp is assigned to identify an address code.

From practice it is known that a corresponding address code by one or two Rotary encoder switch is set, which are assigned to the corresponding lamp. Such rotary coding switches are relatively expensive. Furthermore, there is a risk that in the Installation or subsequently, or in case of replacement or repair the corresponding lamp the address code is not set or set incorrectly.

The corresponding control / monitoring device reads the hardware set Address code of each light off, so that each light for tax and is monitorable.

The invention is based on the object, a lighting system of the aforementioned To improve the way that the corresponding lights safely and easily identifiable with comparatively low installation and commissioning costs.

This object is solved by the features of claim 1.

According to the invention a corresponding unique address code electronically in a Memory device associated with each lamp is stored. hardware Moderate Settings by means of rotary coding switches, for example, are no longer necessary. Because the unique address code by storing the corresponding Luminaire is also assigned, no errors during installation or identification done by the control / monitoring device. Instead, the Address code for luminaire identification of at least the control / monitoring device read out via a data line. In this case, the corresponding Address code already generated during the manufacture of the luminaire for this and in it be filed. When building and initializing the lighting system can then the control / monitoring device the corresponding address code from all Check lights and identify the different lights. Also with exchange a luminaire can the new new address code of the newly exchanged Light quickly retrieved and thus the light exchange can be identified.

As lights, in principle, all lights can be used in an appropriate Lighting system are integrated, such as profile lights, frame lights, recessed ceiling lights or the like, which also formed as a single battery lights could be.

An appropriate lighting system can have several hundred lights comprise, by means of a single data line with the control / monitoring device are connected. However, it is in case of errors in a single data line in the Communication area very difficult to locate sources of error, since all lights communicate over the same data line. By arranging a variety of Lighting on a data line also results in corresponding requirements to the power supply of the particular central control / monitoring device. In this case, the power requirement, the abzudekken by the control / monitoring device is, be relatively high, since each light as a data receiver own power consumption which is multiplied by the total number of luminaires to the total To determine power consumption.

However, to size the power supply for a smaller power requirement, The control / monitoring device can communicate over two or more data lines each connected to a plurality of lights. This also results in a reduced Space requirement for the control / monitoring device, resulting in smaller housing sizes are possible for this device. Besides, in case of a short circuit or any other damage on any of the data lines control and monitoring the lights on the other data lines still possible.

For controlling all relevant lighting functions, such as charge monitoring, mains voltage monitoring, Lamp monitoring, automatic starting of a function and duration tests and their evaluation or to display an operating status such as charging fault, illuminant fault, function test or durability test as well as its test result, the luminaire can have at least one microprocessor. This can also control the communication when connecting a data line take over with the central control / monitoring device.

In case of a power failure, the corresponding data of each The storage device can be stored in a non-volatile, in particular be supply voltage independent storage device. Such Memory device is, for example, in flash, EEProm or other supply voltage independent memory technology executed. The corresponding Memory device may be associated with the lamp from the outside, with it, for example the microprocessor of the lamp via a corresponding interface in Contact is. As a result, for example, lights with hardware setting the address code can be retrofitted so that the manual setting of the Address codes due to automatic, electronic storage are eliminated.

There is also the possibility that the memory device within the Luminaire is arranged in particular on a printed circuit board.

The memory device can in addition to data for the above-mentioned lighting functions contain further data, such as an application program or the like. In addition, a particularly automatically generated serial number is in the memory device can be stored as address code. The automatic generation can, for example be done by a programmer, the storage device with the Program programmed. The automatically generated serial serial number is used in this context as address code or luminaire address in the Storage device stored.

In addition to an electronic readability of the address code in a simple manner also a visual perception of the address code by a person for example in the Installation of the luminaire, each luminaire can be assigned a label, on the at least the address code is specified. In this context, as continue to be considered helpful if the label is a detachable, in particular self-adhesive address portion having a duplicate of the address code. This Address section can then in the installation of the light in a corresponding Installation plan be attached, so that additional identification of the Luminaire at the appropriate installation location in addition to the self-identification by the control / monitoring device is possible.

To indicate further data on the label, if necessary, or completion to wait for the luminaire to generate the address code, after installation of the corresponding electronic module, that is the populated printed circuit board in the Luminaire housing, a regular function test of the complete lamp done and only at or after this bump test then the appropriate label will be printed out. In addition to the address code, further information on luminaire type, article number, Supply voltage, mains frequency, battery assembly, emergency light operating time, Date code (date of manufacture) or the like can be printed on the label.

In particular, to be able to indicate the address code without errors on the label can the address code may be read by a printing device prior to printing. A such printing device or printer reads via a corresponding Data line connection the address code generated during software programming then, for example, print it twice on the label and the corresponding one Address section.

Of course, there is also the possibility that only at the last bump test a corresponding address code is generated and then printed out. It can do that Label also be at least part of the luminaire nameplate.

In order not to attach the label directly to the luminaire, this and / or the Address section of the lamp be enclosed as a separate part. However, label and / or address section may not be lost, the label may also be on the luminaire, on a part of the corresponding electronic assembly, on the microprocessor or the like, the address portion being a detachable one Part of the label is, which then replaced and glued example in the installation plan becomes.

As a rule, after completion of the luminaire installation and connection of all Illuminate via the data lines at the central control / monitoring device a query of the different address codes. These can be, for example, in hexadecimal Range from 0000 to FFFF. After identification of all lights of the lighting system by the corresponding address code, can still every light be assigned an identifier. For this purpose, for example, an input device the control / monitoring device are used, such an identifier may be a clear text of the corresponding light location or the like. The Identifier can also have corresponding correlations for in a group Lights, arranged on a floor lights or the like included. Furthermore can a light as an identifier of the name of a room, the name of certain Positions of a building or the like can be assigned.

By such an identifier can then optionally at a later date be worked without the installation plan, as a corresponding light is easy to identify and locate by the associated identifier. To one such identifier even in case of failure or damage to the central control / monitoring device can continue to use the identifier to the respective Luminaire transferable and be stored in this.

Overall results in the lighting system according to the invention as a further Advantage that, for example, additional programming or configuration tools not are required because the programming of the corresponding lamp during their installation is completed and the configurations of the lights in the lighting system results in a simple way by the query of the address codes. In the inventive Lighting system eliminates the possibility that, for example, a Address code with the hardware coding two or more times or not at all otherwise there will be corresponding difficulties in communicating between the control / monitoring device and the lights result would.

Due to the different data lines for each of a plurality of lights There is also the possibility that corresponding automatic tests for luminaire be performed on a data line while the corresponding tests for the Other data lines are offset in time. This ensures that at least a majority of the lights in normal operation, while only a small Part of the lights is tested accordingly. Such tests are for example prescribed by appropriate standards to the function of the luminaire, deterioration battery capacity or the like.

To the corresponding parts of the lighting system in a simple manner with each other as well as to connect with any further facilities within a building, Lighting and / or control / monitoring device can interface device exhibit. The corresponding communication via the interface can essentially in any known manner, such as TCP / IP, Ethernet, via a fiber optic Connection and the like. The interface device can be used as an external or internal interface device a computer (PC) to be formed.

To directly also in particular on each lamp and possibly also on the control / monitoring device can visually read certain messages z u can Luminaire and / or control / monitoring device at least one status illuminant, in particular LED. Such a status can, for example, be impeccable Operation of a luminaire, the performance of a test, a defect in the luminous means, a charging failure or a battery failure of the lamp or an improper Mark the charge status of the battery. Further status messages are conceivable.

In some lighting systems, the computer (PC) or the like may Control / monitoring device may be provided for the plurality of lights. This is connected via a corresponding interface with the lights on site. The screen The computer is used to visualize different functions, such as Distribution of luminaires, functional readiness of luminaires, malfunction the lights and the like. It can also directly such a computer read corresponding address codes from the lights to identify them. However, there is also the possibility that between such a computer and the lights as interface means the control / monitoring device according to Is arranged invention or computer and interface device, the control / monitoring device form. The interface device then takes over the quasi Communication between lights and computer, by this interface device then the address codes are read out and forwarded to the computer. The computer can still be responsible for other lighting systems that do not have this automatic address code generation and reading.

In addition, corresponding accounts when using a corresponding computer other means to produce, for example, a pressure connection, the otherwise be configured according to the printer model. This can then usually done by the computer.

There is also the possibility of any lamp and / or control / monitoring device and / or the combination of computer and interface device with a central building management device to connect. This can then, for example the corresponding lights on the building management device and the Control / monitoring device to be controlled to certain switching cycles or to do the same. According to the invention, for example, a circuit of a Continuous light part for each individual lamp in a simple manner by the control / monitoring device possible to program daytime switching cycles. Such a switching cycle can, for example, consist in idle times the lighting is reduced to a minimum. Such a switching function for the Continuous light can according to the invention by the control / monitoring device and the corresponding data lines, so that a switched network phase for Carrying out such a switching function, which previously also on the light a light switch or a relay switch contact had to be wired, not more is necessary.

The control / monitoring device and / or the computer may include a memory device, in particular a memory card, and / or a luminous interface device or have interface device or such are associated with the device. The Memory card can contain the corresponding configuration and logbook data. It is easily interchangeable and replaceable with other memory cards.

The switch may preferably accommodated in the housing of the central control / monitoring device be controlled by the corresponding microprocessor such that the connected Luminaires are monitored and controlled in groups. A short circuit in one strand, the monitoring control of all other strings continues to increase. For reasons of compatibility, the luminaire can additionally be an adapter with an addressing device and / or monitoring electronics assigned. The addressing device can be formed in the usual way by decoder or the like. By means of such an adapter with addressing device is possible, the To use lights according to the invention in other lighting systems, in where other control / monitoring devices are used. A corresponding Software may also be provided for the lights according to the invention.

The control / monitoring device or computer / interface combination can by means of a bus connection with further control / monitoring devices and / or the be connected central building management device. This is a simple data exchange between the different institutions possible.

When using multiple bus lines, a corresponding bus multiplexing device be provided.
