Single lamp control power-saving system

Abstract

The invention provides a single lamp control power-saving system which is suitable for the power-saving control of the high-pressure sodium lamp. The system comprises a single lamp controller, an inductance ballast, a single lamp power saver, a starter, a terminal communication device and a monitoring center, wherein the single lamp controller uses a wireless module to send the working state information of the sodium lamp to the terminal communication device through radio-frequency signals; the monitoring center uses the 3G / 2.5G wireless communication module of the terminal communication device to receive the working state information of the sodium lamp, the commands of the monitoring center can be sent to the terminal communication device and fed back to the single lamp controller to control the sodium lamp; the single lamp power saver is connected with the high-pressure sodium lamp to control the high-pressure sodium lamp to work under the designated power; when the sodium lamp works under a high power, the single lamp power saver controls the sodium lamp to work under a lower power; and when the sodium lamp does not require power-saving operation, the single lamp controller controls the single lamp power saver not to work and the sodium lamp works under the normal power.

Description

technical field [0001] The invention relates to a single-lamp control and power-saving system, which is especially suitable for reducing power, dimming and saving power for high-pressure sodium lamps. Background technique [0002] At present, building a conservation-oriented society has become an important national policy of our country. The "Eleventh Five-Year" Urban Green Lighting Project Planning Outline issued by the Ministry of Construction has become an important task for urban road lighting management units. At the same time, it is becoming more and more important. It has been valued by the local government and has accelerated the construction of energy-saving urban road lighting. [0003] At present, the energy-saving work of urban road lighting is mainly based on the application of new technologies, such as voltage regulation and power saving technology for high-pressure sodium lamps, and power-adjustable ballasts for single lamps. At the same time, new light source...

AI Technical Summary

Problems solved by technology

In recent years, with the acceleration of economic development and urbanization, the number of high-pressure sodium lamps has increased significantly, accompanied by a sharp increase in lighting electricity consumption, which has become a major burden on local government finances and sodium lamp users; During the low peak period of electricity, the power supply voltage of the power grid is generally high (higher than the normal working voltage of sodium lamps), resulting in a huge waste of power resources and shortening the service life of sodium lamps
