多功能台灯结构设计.zip

摘要
随着电子技术的日益发展,人们生活中的照明工具也在发生着巨大的变化。普通电灯,白炽灯,LED灯,这也反映了人类社会的进步,科技的发展。目前的家居逐步朝着多功能化智能化的方向发展[12]。随着环境问问题的恶化,能源的减少。节能绿色环保的台灯,逐步走进了人们的生活。以前的台灯用途单一,而现在的人们需要一种多功能智能化的台灯。因此利用所学知识设计一种多功能绿色环保的台灯是一种很好的方向。
本文介绍了一种多功能台灯设计。把单片机技术和PWM调光技术结合起来实现台灯光强的调节。利用软件来改变占空比从而来改变电压的大小实现调光。利用DS1302时钟芯片和单片机结合来产生时间日历。利用DS18B20温度检测芯片来检测环境温度。用1602 字符型液晶显示芯片来显示时间,日历,星期,温度,以及台灯的光强等级。利用蜂鸣器和时钟芯片产生定时闹钟。利用HX1838红外接收来进行红外控制。从而使台灯拥有多项功能。

Abstract
With the development of electronic technology, people living in the lighting tool is also undergoing tremendous changes . Ordinary lamp , incandescent , LED lights. It also reflects the progress and development of human society and technology. The current domestic industry gradually towards multi-functional intelligent direction . With the deterioration of the environment to ask questions , the energy reduction . Green energy-saving lamp , getting into people's lives . Previous use of a single lamp , and now people need a versatile intelligent lamp. So take advantage of the knowledge to design a multi-purpose green lamp is a good direction.
This paper describes the design of a lamp -based intelligent PWM dimming . The microcontroller technology and PWM dimming bine to achieve a strong regulator station lights . Make use of software to change the duty cycle and thus to change the size of the voltage dimming . Using DS1302 clock chip and single-bination to generate time calendar. Using DS18B20 temperature detection chip to detect the ambient temperature. Character LCD with a 1602 chip to display the time , calendar , week, temperature, and light intensity lamp level .Make use of the buzzer and the alarm clock chip to generate timing . For the infrared control using HX1838 infrared that the lamp has a number of functions.
