彩灯向导学术演讲

摘 要

19世纪起来的数字线路以其先验的敏捷的、稳定性的优势在钼中生长着越来越要紧的效能。。跟随男人生活环境的不时更妥和吹嘘,在很多理由,你都能注意变色的跑步灯。LED彩灯鉴于其富产的的照明喊叫声,低成本、复杂把持已被异国涂。,用彩灯来修饰街道和城市建筑物曾经变得一种流行。但目前市场上各式样的LED彩灯向导块用全武器装备电路图实现预期的结果,复杂电路图构架、效能单一,这般,一旦避开制成,它只在一体主力队员的,不克不及鉴于意见分歧的理由、必要意见分歧的时期量子来苗条的照明时期和兑换。
下面所说的事试验的设计,音频变色灯由运算放大器UA74控制、LED液位指示者LM3914、十进制记数制登记簿/圆规CD401的结合,经过音频收回信号可以主动对彩灯或氖管及宴请灯的把持。音频收回信号可以开车把持电路图,如音频变色,把持三色,照着经过努力到达某事物彩灯泡收回千姿百态的喊叫声兑换,其兑换控制与音频收回信号的频率及电平巨大对立应。这般,灯就可以跳了、缓变、定色、象征、五种照明版式,符合的家族、旅馆、舞厅、剧院、海报及等等版图,功能异国,富产的同龄人公民生活。

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 电路图。 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 流行。 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。
