The technical field to which the invention relates

Technical field to which the concept of the present invention is the lighting. More specifically, the concept of the present invention relates to a lighting device, an external device control system and method in the technology of solid-state lighting (abbreviated SSL).

Art

In the presence of readily available now more high-SLL-light sources was desirable instead of implementing lighting systems based on lighting technologies incandescent and fluorescent lighting, make use of SSL light sources for illumination, for example, in offices and in public places such as Department stores and airports. There are several reasons why SSL light sources are attractive as light sources, based on the internal properties of solid-state technology. For example, SSL light sources provide a more energy efficient lighting solutions.

Compared with classic lighting technologies incandescent and fluorescent lighting, SSL devices, such as LEDs and organic LEDs (abbreviated as LED and OLED, respectively) and have different lighting features, for example, the light quality of LEDs is deteriorating modernity is invisible to the eye of the observer, whereas, for example, in fluorescent lighting applications, for example, a visible flicker or the appearance of soot on tubes are a sign of approaching the device to the end of its service life; the quality of light becomes clearly lower than at the beginning of the lifetime of the light sources. Incandescent lamps simply cease to emit light.

For the personnel operating the lighting system, for example, in an office environment, containing a large number of SSL light sources, where each SSL light source can be independently adjusted and, thus, each SSL light source has different hours of burning at the moment, thus, it becomes a daunting task to know which SSL light sources should be replaced as they are nearing the end of life and, thus, have the quality of light below the existing illumination standards. For example, automatic adjustment of light output of lighting devices located near a window, can have the consequence that these lights can provide the number of hours of burning, characterized compared to lighting devices located away from Windows. Different operating conditions, as shown above, make it difficult for staff to know when to replace the light sources.

Therefore, there is R�UK the light source is replaced by a too early stage of its life, becoming as uneconomical and dangerous to the environment in the sense that the light source becomes subject to destruction as waste before its actual quality of the light becomes lower, for example, illumination standards. Alternatively, the light source is not replaced in time, so it will give light following illumination standards or will not give light at all until you call the service personnel to replace the light source in the lighting device.

Replacing all SSL light sources at the same time, the number of light sources having light quality below the standards of lighting, can be reduced. However, as mentioned above, this approach is undesirable, at least from an economic and environmental point of view.

It is known that for the implementation of the software in the SSL light source, in which after a certain number of hours of lighting, SSL light source starts, for example, to flicker, it is necessary to simulate the behavior of, for example, a fluorescent source of illumination reaching the end of its lifetime. US patent 7 425 798 discloses a signal transmission information intelligent detection of deterioration of the led. The signal can be sent through the communication port to notify that light�iodine nearing the end of its period of use.

Disclosure of the invention

This concept of the invention was created taking into account the above and other considerations.

From the point of view of the above, it would be desirable to create an improved lighting device. In particular, it would be preferable to create a lighting device, in order to facilitate its maintenance.

To better understand one or more of these problems, in the first embodiment of the present concept of the invention is provided a lighting device comprising: at least one light source, the diagram (electrical diagram) in order to establish the condition mentioned lighting device and a controller, arranged to control the light output of the mentioned at least one light source based on the above-mentioned condition, so that data on the quality of light relating to the condition, are embedded in the light emitted from the mentioned lighting device. Thus, it is possible to provide knowledge of the current state of the lighting device.

A lighting device may be, for example, an illumination device on the basis of SSL, such as an led device or an organic led device, but it is also possible to benefit device for fluorescent lighting.

Predpochtitel�but the wait staff is performing maintenance of the lighting system that contains a variety of lighting devices, can replace the lighting device and/or light sources that need the service that indicates the status of each lighting device, before any lighting device in the system reaches the end of its life. The end-of-life of the lighting device must be considered as the time when light output (brightness level) no longer corresponds to the existing standards of illumination that can occur because of the need to replace the source(s) light or (part or all) of the electronic circuits of the lighting device at the end of their nominal service life.

Data on the quality of light here is defined as data that describes the state of the lighting device in relation to the end of its useful life. A lighting device may be associated with a unique data about the quality of light that describes the status of this particular lighting device.

In one embodiment, the implementation of the data quality of light may refer to the number of hours of burning light at the moment. Thus, maintenance personnel can more effectively determine when lighting devices� should reach the end of its lifetime. Watch burning at the moment for the light source should be considered as the total number of (working) hours, when the light source is radiated light. Scheme in one embodiment, the implementation may contain a storage device configured to store data related to hours of burning at the moment.

In one embodiment of the storage device may contain a data structure in which the watch burning at the moment for the light source associated with the expected power of the light output during the hours of combustion, wherein said data on the quality of light are referred to the expected output power. Thus, maintenance personnel can more effectively determine when the source(s) of the lighting device needs(HN) to reach end of its lifetime.

Alternatively, the circuit may comprise a sensor adapted to measure the intensity of light output of the lighting device, and the said processor can determine the status of the lighting device mentioned lighting device, and the controller can implement an option to embed data about the quality of light is related to the status of the light emitted by the mentioned lighting device. Thus, can be obtained osvet�tive device, providing information about the state of the lighting device in real time.

Data on the quality of light in one embodiment, the implementation can be integrated in said light only after a predetermined number of hours of burning mentioned lighting device. Thus, it is possible to avoid unnecessary light modulation until it reaches a pre-specified number of hours of burning. Thus, it can be much more energy-efficient lighting device. Additionally, thus, can be reduced wear an electronic component.

In accordance with the second embodiment of the present concept of the invention, is provided a control device, configured to determine the state of at least one lighting device in a lighting system, wherein the control device is external to the at least one lighting device, wherein the monitoring device comprises a sensor, arranged to detect incident light from the at least one lighting device, and the processor is arranged to determine the said state, based on the data quality of light embedded in said incident light.

Thus, effective�e maintenance of the lighting device (s) in the lighting system can be achieved to ensure compliance with existing standards of illumination. Compliance with the illumination standards may additionally, for example, in an office environment, to provide increased efficiency of employees.

Many lighting devices and at least one control device can form an illumination system. The maintenance of such lighting systems can be profitably simplified, and norms of illumination can thus be observed or, at least, can be reduced the risk of non-compliance with the illumination standards.

The control device in one embodiment of the implementation further comprises a communication interface of the control device is arranged to transmit commands mentioned at least one lighting device based on the said condition mentioned, at least one lighting device.

Sending commands mentioned at least one lighting device may occur when determining that the status indicates the end-of-life mentioned, at least one lighting device.

A lighting device may further comprise a communication interface of the lighting device, made with possibility of reception of the mentioned teams, and the said controller is made with the possibility�awn management mentioned, at least one illumination device in accordance with said commands.

In accordance with a third embodiment of the concept of the present invention, is provided a method of maintenance of a plurality of lighting devices in the lighting system, each lighting device is capable of emitting light, in which are embedded the data about the quality of light is related to the status of the lighting device, wherein said method contains the stages at which: detects the mentioned light in the control device that is external to the variety of lighting devices, and determine in the said control device mentioned condition, based on the evidence of the quality of the light.

One variant implementation may further comprise the identification of the said plurality of lighting devices. Thus, the device approaching or have reached the end of its lifetime, can be effectively identified.

In one embodiment of implementation, the identification may be based on the identifier of lighting devices and embedded in said light. For each lighting device of the plurality of lighting devices, thus, a unique identifier lighting us�the device can be embedded in the light, emitted by each of the respective lighting devices.

One variant implementation may further comprise feeding teams at least one lighting device, when the said definition specifies the end-of-life mentioned, at least one lighting unit of said plurality of lighting devices. Each lighting device indicating the end of life, may, therefore, receive commands from the control device.

One variant implementation may further comprise a visual representation, through the mentioned at least one lighting device, the said condition mentioned, at least one lighting device. When at least one lighting device filed team, this lighting device can provide its current condition by a visual indication, for example, the end-of-life. Such visual indication may include a flashing light or safety switch preventing it. Thus, the wait staff can efficiently identify a lighting device that needs servicing operations, such as replacing the source(s) of light. Thus, the external control device may execute�Yat management, when the lighting device(s), up(s) the end of its service life, must submit to it. Preferably, for example, to set the visual blinking to identify the end-of-life occurred only during the maintenance procedures, whereby this visual flashing will not distract the office staff during the working day.

One variant implementation may further comprise embedding mentioned data about the quality of light in said light emitted from mentioned lots of lighting devices and only on request from the control device. Thus can be obtained a more efficient lighting device in the sense that no modulation (i.e. embedding data about the quality of light) of light may not be required in a time when no operation of the service. In particular, the electronics of the lighting device can thus achieve a longer service life.

The above-mentioned and other concepts of the invention will be apparent and explained with reference to options for implementation, described below.

Embodiments of the present conception of the invention will now be described in more detail with reference to the accompanying drawings.

Detailed description of embodiments of the invention

Fig. 1 shows a lighting system 1, the corresponding variant of implementation of the inventive concept. Lighting system 1 corresponding to the invention, may comprise a plurality of lighting devices 2, for example, with SSL light sources such as LEDs, and a control device 3 that is external to the variety of lighting devices 2, the control device 3 may, for example, be operated by service personnel of the lighting system.

In General, the concept of the invention disclosed herein may facilitate the maintenance staff identification lighting devices 2 that have reached or are close to the end of their useful life, when the lighting device 2 or er� components can be replaced. Thus, it can be achieved the levels of brightness in the area to be illuminated, the lighting system 1, brought to illumination standards, such as EN-12464.

An example, not intended to create limitations to explain the overall performance in accordance with the concept of the invention during the procedure, service may be, for example, as follows.

Maintenance personnel may enter the area containing the lighting system 1, having a control device 3. The lighting device 2 can provide invisible to these people about the quality of light embedded in the emitted light of the lighting devices 2, which are detected by the control device 3. The control device 3 may then indicate, for example, via the display, the status of the lighting devices 2 in the lighting system 1. Thus, maintenance personnel can identify the lighting device 2, requiring the maintenance operations in the lighting system 1, and such operations may include the replacement of the light sources 4 and/or replacement of some electronic circuits of the lighting device 2 or completely replace one or more lighting devices 2.

A lighting device is close to the end of its useful life, must here be understood as a lighting device 2, up Windows�ing its lifetime, until the next scheduled maintenance procedures. Therefore, replacement of such lighting devices are desirable when the ongoing maintenance procedure.

Thus, through the control device 3 corresponding to the invention, the lighting device 2, approaching or approaching the end of their useful life, can be easily identified.

Preferably, the concept of the invention can provide improved quality of light, for example, in an office environment or a public place, containing many lighting devices. The quality of light in the lighting system 1 can easily be made to the relevant rules of light. In an office environment, the level of irritability of the office staff can be reduced, since it is possible to avoid visual flicker of the light sources, which is a sign that for a given light source of the lighting device approached the end of life.

Below is a detailed description of examples of embodiments of the inventive concept.

Fig. 2 shows a block diagram of one embodiment of lighting device 2 corresponding to the concept of the invention. A lighting device 2, which may be part of the lighting system 1 comprises, inter alia, at least one light source 4, such as a led, an organic led or other(s) �odobnye(s) of the SSL source(s) of light, the processor 6, clock 7, which may be part of processor 6, a controller 8 and figure 5 to establish the status of the lighting device 2. Alternatively, the light source 4 may consist of a variety of led or other SSL light sources.

Scheme 5 in one embodiment of the storage device contains a 5' to store data about the quality of light is related to the end-of-life of the lighting device 2. Storage device, alternatively, may further comprise an identifier (short ID) lighting device that identifies a particular lighting device 2. If the lighting device 2 includes multiple light sources 4, storage device 5' may also contain at least one identifier of the light source to identify the specific light source 4 of the lighting device 2. Watch 7 can communicate with the storage device 5' to update data on the quality of the lighting devices 2. In this sense, data on the quality of light can be dynamic as they are updated 7 hours.

Alternatively, the circuit 5 may include a photosensitive sensor 5 for measuring the brightness of light emitted by the lighting device 2, and to ensure the supply of brightness data to the processor 6 for processing� these data. The processor 6 may then submit a command to the controller 8 to embed data about the quality of light in the light emitted, based on the measured brightness. Data on the quality of light in embodiments having a sensor 5" should be understood as dynamic, i.e., it contains not only static data but also at least part of the data about the quality of light containing data related to end-of-life of the lighting device, which change over time in the sense that, for example, over time, decrease the brightness levels.

The controller 8, which may be electric start circuit that provides a supply voltage to the source(s) 4 light, can control the light output of the source(s) 4 lights. Can be performed, for example, dimming or modern light modulation, including, for example, switching of the light emitted by the lighting device 2. As mentioned above, data on the quality of light can be received by the processor 6 for supplying commands to the controller 8. Thus, the controller 8 may embed information about the quality of light, and a lighting device identifier and the identifier of the source of light in the light emitted from the lighting device 2. Light modulation is preferably invisible to the people, that is people, preferably not find re�inclusion of light eyes. Methods that can be used for light modulation to embed, for example, data on the quality of light can be, for example pulse-width modulation, phase and pulse modulation, amplitude modulation, frequency modulation, or any other suitable modulation that should be obvious to a person skilled in the art.

Alternatively, a lighting device 2 may include communication interface 9 of the lighting device. Communication interface 9 of the lighting device can be used to supply commands to the controller 8. Such teams can be, for example, the commands dimming or commands from a control device 3 for visual modulation of the light emitted by the lighting device 2.

Some examples that do not create limitations, will be provided here below to illustrate the kind of data related to end-of-life of source(s) 4 of the light, can be embedded in the light emitted from the lighting device 2. It should be noted that within the scope of the invention, there may be several other solutions.

Example 1. Data on the quality of light can indicate the number of hours of combustion at the current moment of the source(s) 4 lights. Watch 7 count the number of hours of lighting at the current moment of the source(s) 4 light and update �upominuemie device 5 that information. Updates can be performed, for example, on an hourly basis or on a daily basis.

Example 2. Data on the quality of light can specify the number of hours of lighting at the moment for the lighting device 2, and the source(s) 4 lights. Watch 7 count the number of hours of lighting at the current moment of the source(s) 4 lights and for lighting device, and update the storage device 5 that information. Updates may be made, for example, on an hourly basis or on a daily basis. The number of hours of combustion at the moment of the lighting device 2 can thus be different from the number of hours of combustion at the current moment of the source(s) 4 4 light, as the light sources may be replaced several times, and the electronic circuit of the lighting device 2 can not be replaced within a few substitutions the source(s) of light.

Example 3. Watch burning at the moment can be associated with the clock combustion of the electronic circuit of the lighting device 2. This electronic circuit can be an electronic circuit, for example, on a printed circuit Board on which is mounted(for example, SSL source(s).

Example 4. The operation of the dimming can be taken into account when calculating the expected time until the end of the lifetime of the source(s) 4 lights. More con�rethen, the storage device 5 may include a lookup table in which for each light intensity can be calculated using the end-of-life of source(s) 4 lights. The lookup table also contains the estimated power of the light output for a specified number of hours of burning at the moment. For example, if the source(s) 4 of the light was(again) in the state 50% of the available light output for 5 hours, it can correspond, for example, 3 hours of burning time with 100% of the available light output. Available light output in this context should be interpreted as the available light output of the source(s) 4 lights with hours of burning at the moment.

Example 5. Lighting device 2 may comprise a plurality of light sources 4, such as SSL (for example, LEDs), each with different color output. If, for example, from the lighting device 2 a more desirable warm light, light sources with red light output can be used more extensively than some other light sources within the same lighting device 2. Therefore, the light sources within the same lighting device 2 can have different end of life. The table view can be provided in a storage device 5 for each specific color,which can be calculated the end-of-life for each colored light source 4.

Example 6. Watch combustion source(s) 4 light associated with the expected power of the light output of the light sources 2. The expected power of the light output can then be embedded in the emitted light as data about the quality of light.

In General, data packets, built-in light, containing, for example, data on the quality of light and the identifier of the light source, can be transferred to the emitted light or by using continuously repeat transmission, or by transmission from a random selection of a time point of transmission. Different fields of a data packet can contain various information of the lighting device 2, such as a field that may contain the identifier of the lighting device. Another field may contain, for example, the number of hours of burning at the moment, for the light source 4. In one embodiment, the implementation of the field may contain information about the expected end of life of the light source 4.

In one embodiment, the implementation provides that the lighting system 1 contains a combination of lighting devices 2 of different types, for example, the first set of lighting devices 2 having the led light sources 4, and a second set of lighting devices 2 having an organic led light sources 4. A packet of data on the quality of light may then contain a field, code no�consisting of a first type of light source 4, as well as a field containing, for example, the number of hours of burning at the moment.

Thus, you may receive assistance for maintenance operations, consisting in the fact that the wait staff can identify which source(s) of light must be replaced.

Fig. 3 shows a block diagram of an embodiment of a control device 3, the corresponding concepts of the invention. The control device 3 can be used in the lighting system 1 to facilitate maintenance of lighting system 1.

In particular, the control device 3 corresponding to the invention may, for example, to provide improved working environment for office staff (for example, norms are light, not visible flicker occurs, which corresponds to the end-of-life, etc.) as well as doing maintenance of the lighting system 1 is more economical and environmentally friendly.

The control device contains, among other things, the photosensitive sensor 10, a processor 11 and the interface 13 of the user. The sensor 10 can detect the incident light, for example, from the lighting device 2, while the CPU 11 may demodulate detection of light that has been modulated lighting device 2. The CPU 11 then interprets the given data, i.e. data about the quality of light to illuminate�professional device 2. Interface 13 user configured to provide the user with, for example, service personnel, data about the quality of light. For example, on the display screen can be represented by the number of hours of burning to date. Thus, the user can determine if the lighting device 2 or the source(s) 4 lights to be replaced, depending on exceeded if the watch burning a pre-specified number of hours of lighting, after which must be met to be replaced.

Alternatively, the CPU 11 may determine whether to perform the replacement of the lighting device 2 or the source(s) 4 of the light, and the result is provided to the user device 3 controls. Such an indication may, for example, indicate the need to replace the LEDs or, alternatively, to display text on the display interface 13 user.

The control device 3 may preferably be a mobile to facilitate maintenance personnel to move it in the area containing the lighting system 1 to perform their maintenance operations.

Examples of the control device 3 can be used in the lighting system 1 will be described below.

Guidance

When the wait staff comes with voblast, containing an illumination system 1, it induces a control device for a specific lighting device 2. In this case, data about the quality of light does not necessarily contain the identifier of the light source, as the wait staff do not know what lighting device 2 is pointed at the device control. Data on the quality of light can, for example, be embedded and transmitted continuously when applying the guidance control device 3, if the lighting device 2 includes a single light source 4. Interface 13 user may then submit the information encoded in the data about the quality of light, such as the number of hours of burning at the moment, and the wait staff can decide whether to replace the light source 4, a lighting device 2 or the electronic circuit, as described above. Alternatively, should there be a replacement, can determine the CPU 11.

If the lighting device 2 has a lot of 4 sources of light (as in the above example where the lighting device 2 has several light sources 4 different colors), such as multiple LEDs, the identifiers of the light sources for each led can be integrated together with information about the quality of light in the light emitted from each light source 4 of the lighting device 2. Dan�s about the quality of the light is preferably incorporated into the light at a scheduled time or by using different carrier frequencies, to reduce the risk of interference data. Identification of source(s) 4 lights needing replacement, will be described in more detail with reference to Fig. 4.

Many of the lighting device

The control device, in this case equipped with optics with a wide field of view, can take light from many or sometimes all of the lighting devices 2, the lighting system 1 immediately. Data on the quality of the light is preferably embedded in the light at randomly selected time instants to reduce the risk of interference data. Alternatively, can be applied to other multiple access methods such as TDMA, FDMA and CDMA. In addition, data on the quality of the light contains the identifier of the source of light for each lighting device 2. In the first example, the interface 13 user provides the number of lighting devices 2 to 4 lights sources that need to be replaced after the control device 3 has collected and analyzed data on the quality of light from the plurality of lighting devices. That maintenance personnel may not be clear what the ID of the light source belongs to a lighting device 2, the wait staff/user of the control device 3 can manually examine each lighting device 2 of the lighting system 1 in accordance with�prepared according to example guidance as explained above, in order to find exactly what lighting devices 2 are in need of maintenance, i.e. what are the 4 sources of light require replacement. It should, of course, be understood that the same method can be used to identify the lighting devices 2 need of replacement, or electronic circuits requiring replacement.

In embodiments in which no communication between the interface connection 9 of the lighting device 2 and an optional communication interface 14, the control device 3 is not performed, data on the quality of the light is preferably transmitted at random times. However, in some embodiments, containing the interfaces 9 and 14 communication transmission between the control device 3 and the lighting device 2 a signal indicating a transition from a regime of multiple sources of light to hover mode, provides for the switching of random data about the quality of light in a continuous flow.

An alternative two-step approach of multiple light sources/guidance is described below with reference to Fig. 4.

Fig. 4 shows a block diagram of an embodiment of an illumination system 1, corresponding to Fig. 1. Each lighting device 2 contains the communication interface 9 of the lighting device and the control device 3 includes an interface 14 with�yahzee control device. Lighting system 1 further comprises a controller 15 connected to the lighting devices 2.

The sensor 10 of the control device 3 detects incident light from a plurality of lighting devices 2. Data on the quality of light from each lighting device 2 is embedded in them the light emitted with random time intervals (as mentioned above, can also be applied to other multiple access methods) to reduce the risk of interference data. The identifier of the lighting device for each lighting device 2 is introduced into the data quality of light.

Alternatively, the identifiers of the light sources can also be embedded in the data about the quality of light.

The CPU 11 then interprets the data as light received from the lighting devices 2. If data on the quality of light contain information indicating that the light source 4 or the lighting device is approaching the end of life, and it is therefore necessary maintenance, the processor 11 provides this information with the corresponding device identifier/light source to the communication interface 14, which, in turn, preferably wirelessly transmits commands based on this information, the controller 15. The controller 15 transmits to�cunt corresponding to a lighting device 2, that is, a lighting device 2, in need of maintenance, through the communication interface 9. Thus, each lighting device 2, approaching or reaching the end of its lifetime, will be notified. In particular, interfaces 9 connection of the respective lighting devices 2 will deliver the commands to the controller 8 of these lighting devices 2. Each relevant controller 8 may then control the light output of their respective source(s) 4 light to identify and present condition, that is, reaching the end of its life defective lighting devices 2. Control the light output may contain, for example, a visual flashing faulty source(s) 4 lights or shutting down the source(s) 4 lights. The wait staff can then replace the source(s) 4 light identified(e) as under(e) end-of-life.

In one embodiment of the lighting device 2 will be to embed your data on the quality of light in the light upon the request of the control device 3. For example, when service personnel should perform the maintenance operation of the lighting system 1, the control device 3 can transmit commands via the interface 14 to the lighting device 2 via the interface 15 connection when giving a command OS�Amiternum devices 2 to start embedding data about the quality of light in their emitted light.

In one embodiment, the implementation of the control device 3 can measure the properties of light, such as the level of brightness of light from another lighting device 2, and the parameters are passed to the respective lighting devices 2 via the interfaces 14 of the communication control device.

Fig. 5 shows a block diagram of the sequence of operations of the maintenance of the lighting system 1.

At optional step S0 data on the quality of light are embedded in the light emitted from the variety of lighting devices upon request from the control device 3. In other embodiments, data about the quality of light is always built into the light or, alternatively, after a predetermined number of hours of burning at the moment for each lighting device 2.

In step S1, the light of the lighting device 2 is detected by the photosensitive sensor 10 of the control device 3.

In an optional step S2 lighting device 2 is identified by the identifier of the lighting device, the built-in light emitted from the lighting device 2. The identifier of the lighting device may contain data about the quality of light. As a variant, the identifier of the light source may also be embedded in the light and, thus, a specific light source 4� lighting device 4 can also be identified.

In step S3 determines the state of the lighting device 2. As described above in more detail, the determination may alternatively contain the identification of the source(s) 4 of the lighting device 2 and/or the state of their electronic circuits. Therefore, determined, reached(whether) whether the source(s) 4 lights and/or electronic circuit of the lighting device 2 to the end of its lifetime. In some specific cases, a lighting device 2 itself can reach the end of its service life, for example, if the number of components on a printed circuit Board of the lighting device has reached the end of their useful life, and wherein the lighting device 2 needs to be replaced entirely.

At optional step S4 to the lighting device 2 of the lighting system 1, which is defined as reaching the end of their useful life or, alternatively, which is close to the end of their useful life, can be filed.

At optional step S5 is the state of the lighting device 2. The status may be represented, for example, service personnel on the display control device 3 (such a display may be part of the interface 13 user). Alternatively, the status of the lighting device 2, if it was determined the end of its service life, can be represented� by the lighting device 2, as described here above with reference to Fig. 3-4. In this case, the control device 3 transmits commands to, for example, the controller 15 of the lighting system 1, in which the lighting device 2 that have reached the end of its life, for example, begins to visually blink on or off, identifying, thus, ourselves for staff. In one embodiment, the implementation of the control device 3 can directly transmit commands to the interfaces 9 connection of lighting devices.

Implementation options for containing the steps S4 and S5, thus, enable the operation of the lighting device 2 and device 3 control as sender and as recipient.

Thus, the control device 3, corresponding to the present invention may apply a command to a lighting device 2, when you want to visually indicate their state in the case of end-of-life or if the end-of-life is approaching.

In General, the illumination system 1 corresponding to the invention can thus effectively eliminate any inconvenience caused by visual flashing or visual flickering light sources of lighting devices and light sources can be effectively used until they comply with the illumination standards. In addition, the illumination system 1 corresponding to us�oedema to the invention, provides a more economical and environmentally friendly maintenance of the lighting system 1.

Application of the concept of the present invention contain, in particular, the environment inside the premises, such as office environments, hotels and shopping malls, as well as the environment outdoors that contain lighting systems. Less effective methods of handling can thus be replaced by the here presented concept of the invention.
