Road lamp electricity-saving method and electricity-saving device

Abstract

The disclosed saving-power method for road lamp is to serial connect a delay-controlled variable-frequency inverse power device to output the tunable sine variable-frequency power for rod lamp. It also discloses the relative road lamp saving-power device and system. This invention holds original power and reduces the lamp current to realize save power efficiently, and needs low modification cost.

Description

technical field [0001] The invention relates to street lamp power saving technology, more specifically, to a street lamp power saving method and power saving device. Background technique [0002] Existing lighting electric lamp (street lamp) mainly is made up of power supply network and lamps and lanterns, bulb etc. In reality, lighting street lamps often use gas discharge bulbs (such as high-pressure mercury lamps and high-pressure sodium lamps) as electric light sources. However, when they work normally and emit light, the electric energy of the power supply network acting on the lamp is continuously delivered, and its output power will not automatically change and automatically adjust according to the time period. That is to say, the electric energy consumption of the electric light depends on the power supply network. [0003] However, there is such a phenomenon in real life, that is, in the middle of the night after the peak power consumption, the voltage of the power...

AI Technical Summary

Problems solved by technology

The effect of this method is not ideal, and the lighting rate according to the national regulations cannot meet the requirements, and the man-hour cost of resetting the power supply line is very high.

There is also a method of lowering the voltage to reduce power consumption. The prominent problem is that it is difficult to start the light after the voltage is reduced, and it is easy to damage the lighting fixtures. The above methods are not easy to implement and popularize.
