摘 要

城市當(dāng)中規(guī)模龐大的路燈系統(tǒng)對(duì)電能的消耗也相當(dāng)可觀，特別是路燈一般需要通宵長(zhǎng)明，路燈的節(jié)能效應(yīng)不可低估。除了在器件上選擇節(jié)能產(chǎn)品和保持合理照度外，通過(guò)控制來(lái)實(shí)現(xiàn)節(jié)能也是很有效的。它通過(guò)使用電力電子器件，單片機(jī)，低壓電器等進(jìn)行調(diào)壓等自動(dòng)控制，降低過(guò)高的夜間電壓,合理調(diào)壓，按時(shí)開關(guān)，使路燈系統(tǒng)達(dá)到節(jié)能的目的。其核心就是設(shè)計(jì)節(jié)能控制系統(tǒng)的電路，特別是使用電力電子調(diào)壓技術(shù)。PWM技術(shù)就是其中之一，他基于單片機(jī)和3525驅(qū)動(dòng)電路來(lái)實(shí)現(xiàn)控制。較傳統(tǒng)方法更加有效，污染較小。通過(guò)3525的特性的應(yīng)用，設(shè)計(jì)控制電路，由輸入基準(zhǔn)電壓控制輸出。

Abstract

In modern large cities, the huge streetlamp system costs so much power, and it must be on work all the night to meet the need of safety, so it is valuable to save energy resources. There are three ways--keep certain lightness, adopting low-power-cost products, and a better control system. The last one will save energy effectively. It works by the drives of the single chip computer, electric electron technology controlling voltage and low voltage electric equipments to save power. The control system will turn down the high night voltage to a usual level. The useful control can adjust voltage, turn on and turn off lights. By now, it is widely used in modern cities and the technology has been advanced, and PWM is one of the technologies. It is more effectively, and crates less harmonic wave pollution than usual method. According to the application characteristic of KA3525，we have designed a kind of PWM control circuit based on KA3525 with the auxiliary of one—chip computer，realized steady voltage and adjustable out putting voltage．

Keywords power saving of streetlamp steady voltage power PWM single chip computer KA3525
