Lighting energy saving device with no flash or overvoltage on basis of logic control

Abstract

The invention discloses a lighting energy saving device with no flash or overvoltage on the basis of logic control, and a control method thereof. The lighting energy saving device comprises an energy saving switch which is successively connected with a fixed energy saving coil and an energy saving coil set in series, wherein the energy saving coil set comprises at least two energy saving tap position coils successively connected in an energy saving circuit in series; the tail end of each energy saving tap position coil is electrically connected with a zero line respectively by an energy saving tap position control switch and is also electrically connected with a tap position assistant buffer control switch; all tap position assistant buffer control switches are electrically connected withthe zero line by a tap position buffer; two ends of the energy saving coil set are connected with load; and a bypass switch is arranged between the live wire end of mains supply and the tail end of the fixed energy saving coil. The invention automatically adjusts power supply state according to the fluctuation of power grid voltage, does not generate overvoltage impact in the state conversion process, does not generate voltage flash and electric arc phenomena and ensures the reliability of load power supply.

Description

technical field [0001] The invention relates to a power saving control device, in particular to a lighting circuit conversion device from power saving to bypass direct connection.
