彩灯班长论题

摘 要

19世纪起来的数字线路以其推理的的机敏的、稳定性的优势在钼中研制着越来越要紧的效能。。跟随男人生活环境的不息胜过和丑化,在很多局面,你都能注意使脸红的跑步灯。LED彩灯鉴于其油腻的的布光肤色,低成本、复杂把持已被普遍地敷用药。,用彩灯来修饰街道和城市建筑物曾经适宜一种调式。但目前市场上各式样的LED彩灯班长绝大多数用全武器装备电流变卖,复杂电流排列、效能单一,这样的,一旦产成品制成,它要不是在独身规则的,不克不及本不寻常的的局面、必要不寻常的的时期量子来修长的照明时期和变异。
这人试验的设计,音频变色灯由运算放大器UA74经营、LED液位线索LM3914、十进制记数制留下印象/配电盘CD401的结合,经过音频发信号可以非本意的动作对彩灯或氖管及享用美食灯的把持。音频发信号可以迫使把持电流,如音频变色,把持三色,到这地步获得彩灯泡收回千姿百态的肤色变异,其变异管理与音频发信号的频率及电平大多数绝对应。这样的,灯就可以跳了、缓变、定色、想像、五种照明设计一个版式,一致的深入地、酒店、舞厅、剧院、海报及宁静领土,目的普遍地,油腻的指印刷中所用的一种字体公民生活。

Abstract
In the 19 century by the rise of digital circuit, stability of congenital advantage in the modern electronic technology plays more and more important in the 电流。 As people living environment and landscaping, continuous improvement on many occasions can see color water 灯。 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 调式。 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 把持。 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 程度。 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 社会。
