Street lamp based on electronic ballast and intelligent control method of street lamp

Abstract

The invention discloses a street lamp based on electronic ballast and an intelligent control method of the street lamp. The street lamp comprises an electronic ballast part for driving and controlling a light-emitting unit to emit lights, and an intelligent control part for controlling the electronic ballast to be started and adjusting a voltage, wherein the electronic ballast part is arranged between a power supply and the light-emitting unit. The intelligent control method of the street lamp comprises the following steps that: (1) an alternating sampling unit samples rectified and filtered voltage state information of an electric supply power grid; (b) a core processing unit carries out comparative analysis treatment on current time information of a clock unit, data information set by a user and data sent by the alternating sampling unit; (c) the core processing unit outputs a switch control signal for controlling a drive and a high-frequency inversion unit of the electronic ballast part to work, and a voltage signal for adjusting the brightness of the street lamp according to a processing result; and (d) the drive and the high-frequency inversion unit of the electronic ballast part adjust a working voltage of the light-emitting unit according to the switch control signal and the voltage signal for adjusting the brightness of the street lamp, which are sent by the core processing unit. According to the street lamp based on the electronic ballast and the intelligent control method of the street lamp, disclosed by the invention, the intelligent control of the street lamp can be realized on a previous wiring basis and the service life of a lamp source is not influenced; and the energy-saving effect is very obvious during a period from 23 p.m. to 5 a.m.

Description

technical field [0001] The invention belongs to the technical field of urban lighting control systems, in particular to an intelligent control method for street lamps based on electronic rectifiers. Background technique [0002] With the rapid development of my country's economy, the road traffic in various cities has been significantly improved. Urban road lighting has become an important part of urban construction. The civilization construction of the city plays an important role, providing an important guarantee for the people's life and economic activities in the city. [0003] However, with the increasing number and scale of street lighting facilities, new requirements are put forward for the quality and energy consumption of street lighting. Saving energy and reducing energy consumption have become the common goal of the world. In recent years, energy prices have continued to increase significantly. As one of the energy sources most closely related to our urban life, e...

Problems solved by technology

[0005] At present, most cities and regions in China almost adopt the cost-saving method of turning off street lamps at intervals. Traditional lighting systems often use inductive ballasts, and lighting fixtures are controlled by a unified switch. The cost is high. Due to the interval of street lamp lighting, the uneven distribution of road illumination has been caused, which has buried hidden dangers for public security and traffic safety; and due to the reduction of electricity consumption by residents in the second half of the night, the grid voltage will increase (the power supply voltage is due to the Electric load decreases and rises by about 15%), sometimes it will be close to 245V, and the actual power of a lamp with a rated power of 250 watts will be 560 watts, which consumes twice as much energy, and the lighting equipment is in an overload working state, excessive heat, both It shortens the life of the light source and increases the maintenance cost, so it cannot be called a real energy saving
