Description

Control method for a lighting

The invention relates to a control method for a lighting according to the preamble of claim 1 and a lighting system according to the preamble of claim 10.

technical field

Such lighting systems are used to achieve efficient and area lighting of roads, streets, or even escape routes. the lamps of operating devices are customarily controlled and activated when required. For such lighting, organic or inorganic light emitting diodes (LED) have recently been used as a light source.

State of the art

For lighting LEDs are also used instead of gas discharge lamps and light bulbs more often as a light source. The efficiency and light output of LEDs is more and more increased so that they already come in various applications of general illumination. However, LEDs are point light sources and emit highly directional light.

But often today's lighting systems have the disadvantage that they can not flexible enough to react to the movement of people or vehicles. Moreover, energy efficiency is becoming increasingly important.

A brightness change and a data communication is often only possible with a complex control circuit, control lines or at least one antenna must be available to send control commands via the control lines or by radio. Summary of the Invention

This object is achieved for a generic method according to the invention by the characterizing features of claim 1 and a generic device according to the invention by the characterizing features of patent claim 10. Particularly advantageous embodiments of the invention are described in the dependent claims.

The inventive solution relates to a control method for a lighting, wherein a plurality of LED lights can communicate in a common illumination system to each other, wherein communication takes place directly over the emitted light of the LED, wherein at least a portion of the lights over a presence sensor a presence of a person or can determine vehicle and the light that has recognized such a presence, the neighboring

Lamps over the communication directly from the emitted light of LED shall provide information on the detected presence.

The solution of the invention also relates to illumination system can wherein a plurality of LED lights in a common illumination system communicate with each other, and communication takes place directly from the emitted light of the LED, wherein at least a part of the lights has a presence sensor for a presence of a person or to determine the vehicle and that transmits light, which has detected such a presence of the adjacent lights on the communications directly from the emitted light of the LED information on the detected presence.

In this way it is possible to achieve a very efficient illumination of a surface by lighting without control lines between the lights would be required. Description of the Preferred Embodiments

The invention will be explained.

Allowing control method for a lighting system, wherein multiple LED lights in a common illumination system communicate with each other, wherein communication takes place directly over the emitted light of the LED. The lighting system can for example be a street lighting system. The lights may be to street lamps or to Pavement markings or curb markings (embedded in the ground marker lights).

The communication directly with the emitted light from the LED can be made by a high-frequency modulation of the light. For example, the LED can be operated in pulsed mode, with the election of the pulse sequence which may be encrypted information to be transmitted. It can take place via the modulated light digital data transmission.

The lights can be in brightness adjust, and by the

Using LED as light source a high flexibility can be achieved here. Preferably, in the lamp, is present at least one switching regulator circuit that can control the power supply to the LED or at least controlled.

The lights can have an integrated control unit which can adjust the brightness of the LED and can control part of the LED in such a way at least that can be made a transmission of information, and thus a communication over the emitted light of the LED. Preferably, the integrated control unit controls the active clocked switch of the switching regulator circuit. At least some of the lamps can have a presence sensor and notice about this a presence of a person or a vehicle. The light that has recognized such a presence may transmit the neighboring luminaires via the communication directly with the emitted light from the LED information on the detected presence.

The lights, which have received the transmitted information about the detected presence can forward it received information about the detected presence to other lights.

The lights, which have received the transmitted information about the detected presence, for example, change their brightness according to the information transmitted. Preferably, the lights increase at least temporarily, their brightness upon detection of a

Presence and / or reception of information on the detected presence.

The lights can the transmitted information about the detected presence of caching, ie the lights are

allowing at least a temporary intermediate storage of the received information about the detected presence of storage means available. They may be in storage means both a non-volatile and a volatile memory. If a non-volatile memory is available, for example, the entire history can be stored on detected presences and to information received and read at a later time, or evaluated. For example, the storage means can be read regularly and an evaluation of the recorded attendances or the frequency of attendances are performed based on the stored data. It can be (for example, by an integrated control unit) evaluated regularly such an evaluation based on the stored data within the lamp itself. Based on this evaluation in the light can be reacted, for example, on the frequency of absences. For example, the basic brightness of the lamps can be increased or prolong the lag time in detecting a presence and increasing the brightness at a high number of presences in a given period. but it can also be reduced, for example, the basic brightness when very few absences for a period of time were found.

However, it is only in the short term cached

Information is analyzed and the brightness control of the lamps to be adjusted accordingly.

The lights can change their brightness based on the sequence of the information provided about the detected presence and also adjust the subsequent behavior in terms of changing their brightness. For example, the background brightness of the lamps may be increased when the short term after the other repeatedly transmit information about the detected presence and received.

Underground brightness quiescent value for the lighting can be understood. It may be that the lighting will never be switched off completely, for example, for security reasons, but should only be held to a low base value, even if no person is present.

The follow-up time refers to the time for which the light maintains the brightness increased upon detection of a presence before it reduces the brightness back or completely off the light. thereby the brightness is preferably gradual, in particular via a slowly progressive ramp lowered, so that a uniform brightness change is achieved. In this case, a reduction to the background brightness can be performed even after the stopping time. The lights can also change their brightness from the detected presence of a person or a vehicle and also adjust the subsequent behavior in terms of changing their brightness. The lights can thus increase their brightness, if the

was recognized presence sensor a presence. Similarly, the lights can increase their brightness when information was received * a recognized brightness.

The lights can also increase their brightness based on the transmitted information and the established presence of a person or a vehicle when can the information about the detected presence of a Middle of a person or vehicle expected. After a predetermined period of time, the brightness can be lowered again, in particular if it can be assumed that no person or vehicle is more present.

For example, each lamp may forward this received information when receiving information about the detected presence and in addition a counter information can be transmitted. These

Counter information may be in a simple case, a number that is to be increased by each lamp, which has received the information about the detected presence of one before this number is passed as counter information together with the information about the detected presence. The counter information can thus as

serve information about the removal of the solid presence provided. In this way, the lights can also recognize at what distance the presence was detected. For example, with an increasing counter value of the brightness of each lamp, increasing their brightness upon receipt of information on the detected presence, be reduced compared to the previous lamps. There may be other information about the communications are transmitted directly through the emitted light of the LED additionally.

The spatial arrangement of the lights within the lighting system may be known to the individual lights or their integrated control units.

Thus, for example, an information about the speed at which a movement takes place of a person or vehicle, are transferred. If the spatial arrangement of the lamps is known, then, for example, each lamp, which itself has a presence sensor, for one to detect the presence itself, and it can receive the data transmitted from other lamps information on the detected presence. It can now pull, for example, from the comparison of the time interval between the reception of the information about the detected presence of any other lamp, and the detection of the presence on his own presence sensor to draw conclusions about the speed of the sensed motion. Having regard to the spatial arrangement of the lights can even addition to the information about the detected presence, information about the location of the lights, which have already recognized a presence about her presence sensor are transmitted. Thus, a spatial analysis on the direction of the sensed motion (ie, the direction of change of presence) take place. Using the spatial analysis of the direction of the detected movement can now be informed specifically more lights over the expected further movement and adaptive brightness for the lighting can be increased where a presence or movement is expected.

In this way, a very energy-efficient illumination is possible, with only the required areas are illuminated at a high brightness in order to ensure the person present there and the vehicle sufficient illumination. At the same time, a high user comfort also is achieved because the lighting can be adjusted, leading adaptive already. So a trodden shortly region can be brightly illuminated in advance, for example, although as yet no presence is detected. If the vehicle or the person reaches this area, it can already be illuminated sufficiently (without the need to wait until to detecting a presence of a presence sensor in this area).

The information can be made by means of a high-frequency modulation of the light, so that the change of the light is imperceptible to the human eye.

For the inventive lighting system in which multiple LED lights can communicate with each other in a common lighting system is the same as mentioned above, the communication directly with the emitted light of the LED. At least some of the lamps has a presence sensor to detect a presence of a person or a vehicle. The light, which has detected such a presence, transmitted the adjacent lights on the communications directly from the emitted light of the LED information on the detected presence.

The lamps may each include a plurality of LEDs, wherein at least a part of the LED emits in the direction of the surface to be illuminated, and at least one LED is arranged so that it radiates in the direction of a neighboring luminaire.

The lamps may each include a receiving means which can receive from an LED of a neighboring luminaire. The

Empfängsmittel can be formed by a light sensor such as a photodiode or a CCD sensor. The lights can have an integrated control unit capable of monitoring the receiving means and thus receiving the emitted light on the information of the other lamps and evaluated.

The receiving means may be formed by a run in the reverse operation LED. This operated in reverse operation LED can be respectively operate only for a brief moment in the reverse operation, and for the remaining time as the LED in the forward direction (ie for light emission) are operated. It can be present, which can run in reverse operation LED monitor and receive the transmitted information in this way and evaluate a receiving circuit. The

Receiving circuit can be part of the integrated controller of the lamp or as an additional circuit may be provided which is monitored by the integrated controller of the light and evaluated.

The presence sensor may be formed to detect a presence of a person or a vehicle through a motion sensor, preferably by a passive infrared sensor. But the presence sensor can be formed with motion detection by another type of sensor such as a radar sensor or a camera.

The lights can additionally include other sensors such as light sensors for detecting the ambient brightness. Also, the detected signals of these sensors by the lighting (in particular its integrated control units) are evaluated, and are transmitted as additional information about the light to the other lamps.

Preferably, the lamps are not connected via a wired or wireless-based bus system, but it is possible that an additional interface is provided in the luminaire, for example, to read data, or even for a slow data transmission. The illumination system may also have control panels that are either integrated into some of the lights or can drive the LED at least for individual lights. The control units can transmit additional information about the light at the lights of the lighting system. It may, for example, general brightness commands or system information (such as time information or a call already set out in the lighting scenes or flowchart) act.
