许建成
摘要:
LED彩灯在我们的日常生活中是随处可见的,无论是美化、亮化工程,还是企业的宣传,都可借助于广告屏的形式,使得各个城市的夜晚光彩夺目。LED彩灯由于其丰富的灯光色彩,低廉的造价以及控制简单等特点而得到了广泛的应用,用彩灯来装饰街道和城市建筑物已经成为一种时尚。彩灯在我们的日常生活中是随处可见的,无论是美化、亮化工程,还是企业的广告宣传,都借助于彩灯的形式,使得各个城市的夜晚光彩夺目,滨彩纷呈。这些彩灯可以是用霓虹灯管制成各种形状和各种颜色的灯管,也可以是采用白炽灯或者日光灯作为光源,照亮大幅的或巨幅的宣传画。彩灯控制能达到的渲染效果,是通过控制全部或者部分彩灯的亮和灭、闪烁的频率、灯的亮度和灯光流的方向来实现的。在不太复杂的彩灯控制中,一般可采用单片机或者各种专用的彩灯控制器,本设计采用PLC来完成设计。

Abstract:
LED lantern in our daily lives is ubiquitous, whether landscaping, lighting engineering, or business information, can aid in the form of advertising screens, dazzling night to various cities. Lamp light color that LED illumination enriches because of the person, cheap cost of construction waits for a characteristic as well as controlling a simplicity but the decoration neighbourhood and the city building already e one kind of ing having got the illumination applying , using broadly. Illumination is to be able to be seen everywhere in our daily life, regardless of be beautify, light spends a project , is still the enterprise advertising, be backed by the illumination form, will do each cities's night is oriency , the shore color appears numerously. These illumination can be to use neon to control the fluorescent tube ing the various form and various colour , also can be to adopt the incandescent lamp or the daylight lamp to be an illuminant , illuminate the wide or huge picture poster. Illumination is controlled being able to reach exaggerating effect , is is under the control of all pass or e true part illumination light and the direction that go out , evasive frequency , light brightness and lamp light stream. Control middle in not plicated illumination , may adopt the monolithic machine or the special-purpose various illumination controller in general , design that
