METHOD AND DEVICE OF POWER-SAVING CONTROL OF STREET LIGHTING Russian patent published in 2014 - IPC H05B37/02 

FIELD: electricity.

SUBSTANCE: method and device are proposed for power-saving control of street lighting, which consist in autonomous adaptive street lamps during the day depending on duration of a light day calculated for every day of the calendar year for this geographic area, and also road traffic intensity. The technical objective of the proposed invention is aimed at increasing energy efficiency and safety of street lighting control. The method provides for functioning of the lighting system in a power-saving mode (mode of lamps dimming), which is subdivided into the basic and optimal power-saving mode. The basic power-saving mode is the mode, when street lamps are dimmed for the knowingly permissible interval of time. The optimal power-saving mode is the mode, when duration of the power-saving mode is maximum for the current date. In the case when values of time for switching on and off are not defined for both optimal and basic power-saving mode, the power-saving mode in the subsequent cycle of operation of street lamps is not switched on. The device comprises a source of light, a power supply unit, a unit of adaptive dimming, a sensor of road traffic intensity (option), and makes it possible to carry out autonomous adaptive dimming of street lamps during the day.

EFFECT: reduced costs for electric energy for lighting needs and costs for creation and operation of communication lines between lamps and automated switching points.
