FIELD: luminescent lamps.
SUBSTANCE: device has four diodes, making up a bridge rectifier, two adjacent shoulders of which are linked by capacitors and connected to first input of bridge rectifier which is connected to first clamp of alternating voltage source. Second clamp is connected through ballast to second input of bride rectifier. Positive output of bridge rectifier is connected to serially interconnected diode and resistor, luminescent lamp and diode with negative output of bridge rectifier. Capacitor is connected in parallel to luminescent lamp. Between serially connected diode and resistor and second input of bridge rectifier capacitor is connected. Between second input of bridge rectifier and output of luminescent lamp second capacitor is connected, two adjacent shoulders, connected to first input of bridge rectifier, each of which is connected by direct resistor, and ballast is made in form of capacitors, each of which is linked by direct resistor, connected through switch to second clamp of alternating voltage source.
EFFECT: lower costs, higher durability.
