Brief description of drawings

Below will be described the present invention with reference to the accompanying drawings, in which:

Fig. 1 is a block diagram of the regulator;

Fig. 2 shows a typical application of street lighting system.

A detailed description of the preferred options

for carrying out the invention

In Fig. 1 shows a block diagram of the electronic controller 100 with the Central electronic unit 106 connected to the lighting fixture 101. The regulator usually has the following functions:

- completely disables the light (OFF) 102;

- supports light in standby mode (READY) for a rapid response in the case of immediate needs 102;

- regulates the AC light signal output from minimum to maximum (INCLUDED) 102;

- establishes communication with the appropriate regulators attached to the nearest lighting fittings 103;

- control section - usually identical sections, illuminated adjustable light with respect to events of interest, for example, people who are on section ladaily animals or of objects moving within a partition or incoming, or outgoing section, for example, by camera 104;

- identifies conditions ambient light 105;

- decides on its activities to the lighting on the side (1) information from its own sensors and (2) of the reported information from regulators at the next light fittings.

In Fig. 2 shows a typical system 5 (as an example) lighting fittings 201-205, located at a distance from each other along the street lighting 5 "sections" of the street. Section overlap each other, as is usually the case in the field of lighting. Each lamp is functionally controlled by the electronic controller 211 to 215 mounted on the fixture.

The following describes one possible implementation of the system functioning: all the lamps, which are supposed to belong to the type of lamps requiring a time-consuming preheating, as expected, are in a state of READINESS, as recently on any of the monitored sections found no object, and there is very little ambient light is at night, so that the regulators are in the wait state required coverage.

The vehicle 200 is approaching on the left, and this event, which includes extending the s and the speed of approach - is controlled by the controller 211. Since the controller 211 has not received any messages from the controller to the left of the lighting fixture, it increases the coverage to the value that provides the lighting, but without blinding the driver of the vehicle. In addition, the controller informs about this event and the parameters such as speed and direction, adjacent to the controller 212, which later will be to drive the vehicle. The controller 212 then increases the light from the READY state to the level that makes the driver of a vehicle more accustomed to the light that provides the opportunity to increase coverage further than the regulator 211, without blinding the driver. Further, the controller 212 distributes information about the event the vehicle approaches the next controller 213, which, in turn, can prepare for the approaching vehicle.

In another embodiment, the invention is a lighting system along the street for a stay of the vehicle only at one end of the street - light sources 205, far removed from this end of the street, could be even the night mode OFF, so how could they be capable of pre-heating at an appropriate time prior to arrival of the vehicle. This opens up opportunities for greater e is anomie energy and increased service life of lighting equipment.

Inside the section, controlled by the regulator, is not recognized any significant object, and the relationship with the immediate regulators indicates that no object is approaching from outside its own section, the regulator reduces the lighting to minimum (OFF or READINESS depending on the above conditions).

Recognition of the direction and speed of objects can be performed by image processing, if the identified equipment controller contains electronic camera and sufficient computing power for image processing, or through additional communication between two or more controllers that control the overlapping section. Additionally, there may be used conventional means, such as radar, laser or electromagnetic sensor that is built into the lane.

Lighting system, located along the street, you can usually use a structured communication network. Theoretically, each controller is connected only with its two adjacent regulators ("neighbors")that use the reported information and in addition - if you skip a modified or unmodified information to the next controller. However, in cases when it should be lit smaller structural space could be required and other, who is one, unforeseen way communication. Therefore, regulators usually can communicate with any other controller within the system, as means of communication (cable network, radio) technically allow this connection. This choice is also useful to support reliable operation in cases where some sources 204 light (no light) or regulators 214 (no signal) fail and cannot participate in the communication.

In an additional embodiment of the invention, special attention can be given to objects within the system in unexpected places or otherwise unexpectedly behave, for example, large animals belonging to the street, the cars moving in unauthorized areas, staying in unexpected places (due to flat tires, engine failures ...), and such events. In this case, the controller may run special lighting and/or communication programs that can be called upon to pay attention to this event to improve security in this area.
