Description

A sort of led Street Light Controller

technical field

The present invention relates to the technical field of LED street lamps, in particular to a controller for LED street lamps.

Background technique

Street lamps are an important part of urban lighting. With the acceleration of the modernization process of urban road lighting, the street lamp monitoring system has received more and more attention. LED street lamps often use high-efficiency white light diodes synthesized by GaN-based power blue LEDs and yellow phosphors. They have unique advantages such as high efficiency, safety, energy saving, environmental protection, long life, fast response speed, and high color rendering index. They have been widely used in urban lighting. building.

In recent years, many cities in China have begun to adopt intelligent street lamp control technology to intelligently transform traditional street lamps. With the rapid development of urban construction, the number of road infrastructure lighting facilities continues to increase, the contradiction between energy supply and demand is becoming more and more prominent, and the requirements for energy saving and green lighting are becoming more and more urgent and higher. The traditional street lamp method is to rely on the maintenance personnel to drive around when the lights are turned on, and only to solve the equipment failure. Due to the problem of human and material resources and the responsibility of the maintenance personnel, it often occurs that the street lamps in some areas do not light up for a long time, and the resulting social problems Problems will have a great negative impact on city managers.
