Problems solved by technology

[0005] Excessive lighting and lighting ineffective energy consumption are widespread in public lighting
Often in the dead of night, there is no one in the place to be illuminated, but the lights are brightly lit, wasting a lot of electric energy
Taking urban road lighting as an example, in response to this situation, many places are implementing the "midnight lights, every other light" mode, but this will cause uneven brightness on the road surface, easily cause visual fatigue, induce accidents, and also violate the current road Lighting Code Requirements

Abstract

The invention relates to the technical field of electric power regulating and controlling equipment, in particular to a direct-current centralized power supply dimming system and method for public lighting. The system is characterized by being provided with an alternating-current input unit, an AC / DC conversion unit, a monitoring unit and a direct-current output unit. Compared with the prior art, the direct-current centralized power supply dimming system and method are particularly suitable for lighting in public places, energy consumption of a lighting system is reduced, the service life of a lamp is prolonged, daily maintenance cost of the lighting system is reduced, and power distribution three-phase load balance of the lighting system can be achieved.

Description

Technical field: [0001] The invention relates to the technical field of power control equipment, in particular to a lighting system that is especially suitable for lighting in public places, can reduce the energy consumption of the lighting system, improve the service life of lamps, reduce the daily maintenance cost of the lighting system, and make the lighting system A DC centralized power supply dimming system and method for public lighting with three-phase load balancing for power distribution. Background technique: [0002] Public lighting, such as road lighting, park lighting, square lighting, and public part lighting of buildings and halls, as well as landscape lighting, is one of the public facilities with the highest density and number in the city, which is related to road traffic safety and the convenience of people's lives And urban beautification, and become an important part of modern urban landscape and people's daily life. The implementation of DC power supply...
