FIELD: electricity.
SUBSTANCE: lighting system comprises multiple lighting units (1, 4), each configured to illuminate a target area. There is a central element that reduces the light force and has controlled conductivity. Each lighting unit comprises at least one source (101, 201) of light, a controlled exciter (2, 5) of the source of light, connected to the source of light (101, 201), and a light sensor (3, 6) configured to measure the light flux in the target area of the lighting unit (1, 4). The exciter of the light source supplies energy to the source of light in accordance with input control voltage generated by a source of current. The light sensor is connected to the current source and has alternating conductivity corresponding to the light flux. The light force of the lighting units (1, 4) may be reduced in a combination by means of connection of each sensor (3, 6) of light in parallel with an element (7) reducing the light force via an appropriate diode (9, 10, 13).
EFFECT: improved energy efficiency of a lighting system.
