FIELD: lighting.
SUBSTANCE: invention relates to lighting fixtures with possibility to control LED current values and providing various electric connections. Result is achieved by fact, that applied exciting voltage is divided, and divided voltage is compared with reference voltage for generation of digitization signals. Logical operation is performed over digitization signals for switching control signal generation and current control signal. Switching control signal controls electric connection of LED, to which excitation voltage is applied. Besides, current control signal may select LEDs, which must perform light emitting operations. Target voltage is set by digitization signals processing and used to determine LED excitation currents, which must perform light emitting operations.
EFFECT: technical result is higher reliability of lighting fixture.
