摘要随着科技的发展，越来越多的电器入驻每个家庭，各式各样的电器不断向着智能化 和人性化的方面改进和发展，使人们的日常生活更加便利。而台灯作为每家每户必备的 生活用品，对台灯进行进一步的设计和优化，让它的功能更加完善，更贴近现今环保社 会的要求，至关重要。而 LED 灯作为绿色照明光源的代表产品，它的各项特点都符合人 们的日常生活，节能低碳、绿色环保已经是现在社会生活的代名词，并且中国已经在面 向社会推荐这一绿色环保的 LED 灯作为日常的照明电器，所以，这次我们提出了由 51 单片机为主要芯片的智能台灯这一设计。

这次，我们选用了 STC89C51RC 单片机，作为整个设计的核心，围绕单片机设计出 拥有多种功能的智能 LED 台灯。台灯有两种调节方式：手动、自动；并且有另一种功能： 呼吸模式。整个设计的硬件设计部分分为几大模块：一、单片机控制模块：芯片是我们 这次设计选用的主控芯片；二、LED 指示模块：本次设计因为有几种不同的工作模式， 需要对此加以区分，方便使用，所以选用了三种能发出不同颜色的小 LED 灯来对不同的 工作模式进行区分；三、按键模块：按键模块的设置，主要是用于手动模式，方便使用 者手动调节 LED 灯的亮度以及手动选择三种工作模式；四、照明模块：顾名思义，就是 用来发光照明的，这里我们选用了草帽型的 LED，并且使用了 12 个这样的白光 LED，以 此来加强光照的亮度；五、光敏模块：这一模块的设计主要用于自动控制电路，对于不 同的外界光敏信号进行采集，并用 PWM 调光技术来自动调节 LED 的光度。73951

Design of intelligent desk lamp based on 51 single chip microcomputer

Abstract With the development of science and technology, more and more electrical appliances in each family, all kinds of electrical appliances constantly towards intelligent and humanization of improvement and development of the People's Daily life more convenient。 Every household and desk lamp serves as the necessary articles for daily use, the desk lamp for further design and optimization, make its function more perfect, more press close to the requirements of today's environmental protection society, is of crucial importance。 And LED lighting products as a representative of the green lighting light source, its various characteristics meet the People's Daily life, energy saving low carbon, green environmental protection is now synonymous with social life, and China has been geared to the needs of

society recommend the green LED lights as part of their daily lighting appliances, so this time we put forward by 51 single chip microcomputer as the main chip intelligent lamp this one design。

This design, we adopted STC89C51RC MCU as the core of the whole design, around 51 single chip microcomputer is designed with a variety of functions of intelligent LED desk lamp。 Desk lamp has two kinds of adjusting method: manual and automatic; And there are another function: breathing pattern。 The whole design of the hardware design part is composed of several big modules, a, single-chip microcomputer control module: the master control chip is we design this time choose chips; Second, the LED indicator module: because there are several different working mode, the design need to distinguish between, easy to use, so I choose three can make different color of small LED lights to distinguish between different working mode; Three, key modules: module Settings, is mainly used in manual
