Problems solved by technology

However, the current power supply system for lighting fixtures is powered by a step-down transformer with a fixed ratio, and the output voltage is not adjusted according to the brightness required by the actual lighting fixture. The service life of lamps and lanterns also causes the waste of electric energy

Abstract

The invention provides a lighting power-saving device, comprising: a box body; a lighting lamp circuit in the box body, the circuit includes an induction voltage regulator TB1; a motor; a bypass switch circuit; a manual control circuit; an automatic control circuit; The input terminal of the switch TB1 is connected to the contactor KM2 and the AC power supply, and its output terminal is connected to the contactor KM3 and the lighting fixture; the bypass switch circuit and the manual control circuit are connected between the AC power supply and the lighting fixture; the automatic control circuit includes: detection module CT And the programmable controller PLC composed of CPU and analog input module, the automatic control circuit is respectively connected to the intermediate relay that controls the action of the induction voltage regulator TB1, the motor, and the bypass switch circuit. The beneficial effect of the invention is: when the input voltage is lower than the lower limit, the output voltage can still be guaranteed to meet the requirement. It can detect the grid voltage in real time, adjust the voltage output according to the input voltage and the lighting period, and the power saving rate is greater than 20%. With bypass switch, multiple electrical and mechanical interlocks, high availability and reliability.

Description

technical field [0001] The present invention relates to a power saving device for lighting electricity, in particular to a power saving device for street lamp lighting. Background technique [0002] At present, when various types of lamps are used for lighting, the lamps are usually directly connected to the relevant power supply through the control switch. Different electrical loads are used in different time periods, and the power supply voltage is allowed to vary within the rated value -10% to +15%. According to the requirements of the management of lighting fixtures, the lighting of lighting fixtures is required to have different brightness in different time periods. For example, the brightness of lighting fixtures from 18:00 to 24:00 is stronger than the brightness of the lighting fixtures in the dead of night after 24:00. However, the current lighting fixture power supply system is powered by a step-down transformer with a fixed ratio, and the output voltage is not ad...
