The input side of lighting system shall be quipped with a PLC transmitter-controller, and its output side, i.e. the lamps themselves — shall be equipped with appropriate receivers. Normally, luminaires are equipped with tradi-tional dimmable devices with a 1-10 V interface.

PLC allows establishing communication between control element and dimmable lamp without installation of additional network for data exchange. Each luminaire has its own ID number.

The system maintains its operability, while the operator can regulate lighting intensity of separate group of luminaires, as well as of one single lamp within certain interval ranges. For example, the system may increase lighting intensity during cultural events performed in a separate part of a city or town during nighttime. As an example, provide additional local lighting for cultural events in a separate part of a city or town in the evening.

The diagram demonstrates example pattern of lighting system operation from 21:00 p.m. to 05:10 a.m. on March 21st in Almaty city. Another pattern of system operation can be set depending on seasons and regions, and daylight length. The red zone indicates the level of energy saving. The red dotted line indicates twilight, when drivers experience the greatest discomfort while driving. During this period, the lighting operates at a maximum level. Period from 21:00 to 23:00 — lighting brightness decreases, energy savings — 20%. Period from 23:00 to 01:00 — lighting brightness decreases, energy savings — 50%.

Period from 01:00 to 04:30 — maximum energy savings — 80%. Period from 04:30 to 05:10 — beginning of the astronomical dawn.

The dimming system gradually increases lighting brightness up to 5:10 am; at twilight, the lighting operates at maxi-mum brightness to prevent road traffic acci- dents. Time of astronomical sunset/sunrise based on 21st of March — the spring equinox. This is an average indicator for the calendar year. Consequently, data is prepared for Almaty city. In case if system operates in another city, if the system will automatically reset according to
geographical coordinates of operation region.

The PHOENIX intelligent control system allows you to monitor and control lighting by exchanging data both over power lines and using wireless technologies, without the need for additional data cables. Lighting control can be carried out both automatically (without operator intervention,
according to a pre-installed program), and in manual mode.
The PHOENIX system is able to turn the lighting on and off according to the astronomical calendar (sunrise/sunset) programmed into the memory of the controllers, as well as change the brightness of the lamps depending on the time of day according to the set schedule. Our software allows the dispatcher to control both one specific luminaire and the lighting of an entire country anywhere in the world. In addition to the main functions listed above, the PHOENIX lighting
control system allows you to:

• Remotely control the brightness and color temperature of street lights.
• Remotely monitor the status of equipment and fixtures in a single control center (street, district, city, country).
• Collect statistics on electricity consumption and savings, as well as on other parameters of the power grid.
• Lighting switching on and off according to the light sensor, and according to weather conditions (fog, smog, thunderstorm, strong wind).
• Isolated operation of the system (OFFLINE mode), in cases, when communication with the control center is absent.
• Notify about opening of equipment cabinets and unauthorized connections to the line.
• Notify about problems with the supply or outgoing lines.
• Control equipment temperature.

Dark or poorly lighted streets, flashing, dim or non-operating lights – the situation is very familiar for citizens. The “brighter” future of our streets is inseparably associated with their quality lighting. Sufficient lighting of roads, pedestrian footpaths and side-walks, squares and parks, creates not only a comfortable and attractive atmosphere of evening cities, towns and villages, but contributes to improving of road traffic accidents preven-tion and reducing of crimes. As a result, citizens and tourists walking down the streets in the night city will become a natural component of city life.
