Problems solved by technology

This electronic ballast for high-pressure sodium lamps can only adjust the output power of high-pressure sodium lamps during periods of low lighting effect requirements, but cannot automatically adjust the input voltage of sodium lamps according to changes in grid voltage. The voltage situation is adjusted to achieve the purpose of saving electricity and energy

Abstract

The invention provides an environmentally-friendly intelligent high voltage sodium lamp economizer, comprising a voltage processing device, a detection control device and a voltage-transforming device, wherein a single-chip of the detection control device judges the current intensity input by a detection end and selects a corresponding signal end to continuously output a starting signal, each switching circuit of the voltage-transforming device, an inductance component, a sodium lamp and an external power supply form a loop, and the inductance values of the inductance component in each loop are different and are determined according to a voltage reduction value required by an external power supply voltage relative to the normal working voltage of the sodium lamp when the corresponding switching circuit is switched on. The invention has the advantages that light can be regulated according to setting parameters, such as road grade, regional grid characteristics of users, road conditions, and the like, the economizer per se has extremely low power consumption and can save the power consumption of the high voltage sodium lamp by more than 40 percents, reduce lamp-replacing cost and maintenance cost and work in high temperature and low temperature environments and humid environment.

Description

technical field [0001] The invention relates to an energy saver, in particular to an environment-friendly intelligent high pressure sodium lamp energy saver. Background technique [0002] There are obvious peak and valley periods in electricity consumption in major and medium-sized cities in my country, and the voltage changes in peak and valley periods of electricity consumption in urban areas are more prominent. After 23 o'clock in the middle of the night, the electricity consumption of residents and enterprises drops sharply, tending to the valley period. At this time, the current in the power supply line is relatively reduced, the line loss is reduced, and the voltage rises accordingly. For a 380-volt street lamp circuit, the line-to-line will generally be 10-30 volts higher. Since the power consumption of the street lamp is proportional to the voltage, the street lamps working at this time are much higher than the rated power. At present, most street lamps use high-pre...
