彩燈控制器畢業(yè)論文


摘 要

19世紀(jì)興起的數(shù)字電路以其先天的便捷、穩(wěn)定的優(yōu)點(diǎn)在現(xiàn)代電子技術(shù)電路中占有越來(lái)越重要的地位。隨著人們生活環(huán)境的不斷改善和美化，在許多場(chǎng)合可以看到彩色流水燈。LED彩燈由于其豐富的燈光色彩，低廉的造價(jià)以及控制簡(jiǎn)單等特點(diǎn)而得到了廣泛的應(yīng)用，用彩燈來(lái)裝飾街道和城市建筑物已經(jīng)成為一種時(shí)尚。但目前市場(chǎng)上各式樣的LED彩燈控制器大多數(shù)用全硬件電路實(shí)現(xiàn)，電路結(jié)構(gòu)復(fù)雜、功能單一，這樣一旦制作成品只能按照固定的模式閃亮，不能根據(jù)不同場(chǎng)合、不同時(shí)間段的需要來(lái)調(diào)節(jié)亮燈時(shí)間和變化。
本實(shí)驗(yàn)設(shè)計(jì)中，音頻變色燈由運(yùn)算放大器UA741、LED電平指示器LM3914、十進(jìn)制計(jì)數(shù)/分配器CD4017組成,通過(guò)音頻信號(hào)可以自動(dòng)對(duì)彩燈或霓虹燈及節(jié)日燈的控制。音頻變色等控制電路可在音頻信號(hào)的驅(qū)動(dòng)下，控制三基色，從而達(dá)到彩燈泡發(fā)出千姿百態(tài)的色彩變化，其變化規(guī)律與音頻信號(hào)的頻率及電平大小相對(duì)應(yīng)。在這樣燈光可實(shí)現(xiàn)跳變、緩變、定色、組圖、照明五種形式，適用于家庭、賓館、舞廳、劇院、廣告等領(lǐng)域，用途廣泛，豐富現(xiàn)代社會(huì)生活。

Abstract
In the 19th century by the rise of digital circuit, stability of congenital advantage in the modern electronic technology plays more and more important in the circuit. As people living environment and landscaping, continuous improvement on many occasions can see color water lamp. LED lights because of its rich light color, low cost and simple control characteristics and a wide range of applications, with lights decorating streets and city building has become a kind of fashion. But on the market at present each style LED lights controller hardware circuit realized with the most complex structure, function, circuit, so when making a product with only fixed pattern according to different situations, shiny, different period of time to adjust to changes and light.This experimental design, audio amplifier UA741 discoloration of light, LED by LM3914, decimal indicator level CD4017 distributor/counting, through the audio signal can be on holiday lamp lights or neon and control. Audio control circuit can discoloration of audio driver, control, thus achieved the effect of various issued the variation color changes, with the audio signal frequency and size of corresponding level. In this light can realize jumping, slowly, color, atlas, lighting five forms, applicable to family, hotel, ballroom, theatres, advertising and other fields, versatility, rich life in a modern society.
Key words: audio color lamp lights CD4017 audio signal
