Single-lamp variable power control system of high voltage sodium lamp

Abstract

The invention discloses a power-variable single lamp control system of a high voltage sodium lamp. The power-variable single lamp control system comprises a power-variable single lamp controller, a power saver, a power-variable data concentrator and a power-variable single lamp system management platform, wherein the power-variable single lamp controller is electrically connected with the high voltage sodium lamp through the power saver; the power-variable single lamp controller and the power-variable data concentrator are connected for transmission through a wireless network; and the power-variable data concentrator is used for receiving command data sent by the power-variable single lamp system management platform. The single-lamp variable power control system disclosed by the invention has the following beneficial effects: based on an IoT (Internet of Things) technology modularized hardware design, the single-lamp variable power control system is low in cost, small in size and convenient in installation and maintenance; and meanwhile, a voltage closed loop feedback mechanism is used for performing power reduction control, so that a condition that high voltage sodium lamp blackout is caused by a power reduction operation executed under a lower voltage condition can be avoided.

Description

technical field [0001] The invention belongs to the technical field of power regulation controllers, and in particular relates to a single-lamp variable power control system for high-pressure sodium lamps. Background technique [0002] With the deepening of the country's economic development and the acceleration of urbanization, energy demand and consumption are increasing. Energy conservation has become the consensus of all walks of life and one of the goals of economic development. The urban green lighting project plan of the Ministry of Housing and Urban-Rural Development clearly puts forward The quantitative goal of accumulative energy saving for urban lighting has been set, and various energy-saving technologies have also emerged and developed. The largest number of urban functional lighting-street lamps have become the main energy-saving control objects, and street lamps can generally achieve energy saving by reducing power. Effect.

AI Technical Summary

Problems solved by technology

[0004] Preset power inductive ballasts need external equipment for switching control to achieve energy-saving effects. At present, the power reduction control is implemented using a timer. After the timer starts counting, the power reduction control operation will be performed after the preset operation time is reached. After a period of use, users generally report that the fixed time timer will cause the power reduction time to be unreasonable, because the four seasons of the year The sunset time varies greatly, and the power reduction time suitable for summer is not suitable for winter, so it is a reasonable energy-saving control method to be able to flexibly control the time of power reduction

At the same time, it was found in some experiments that, for lines with low voltage, the power reduction operation may cause the lights to turn off, so the open-loop control method without feedback mechanism needs to be improved.
