基于人体感应照明灯的设计

人体感应照明灯设计

摘要

进入21世纪，人们的生活水平逐渐提高，伴随着环保事业的兴起，人们的环保意识也在逐渐的提高。节能减排成为了我们生产生活中必须要注意和重视的一个问题。人体感应照明灯设计通过对人体散发微量红外线的监控可以达到人至灯亮、人走灯灭的效果，避免灯具长时间工作对能源的浪费。

这样的好处在于，白天，由于光线照射，该灯始终处于关闭状态，一到晚上，在黑暗中，该灯只要收到一个人体红外信号，灯就自动点亮，而后人离开时，自动熄灭，可以达到节电的目的，其装置省去了能耗大、笨重、极易产生热量的电源变压器，具有结构简单、自耗电轻微、性能稳定、灵敏度高、通用性强的特点。

Design for human body induction lamp

Abstract

The 21st century, the people's living standards gradually improved, along with the rise of environmental protection awareness of the environment is gradually improving. The design for human body induction lamp to turn the light on or off when humans come or go, which can prevent the waste of election.

There is good at daytime, due to the light, the light is always turned off, one night, in the dark, the lights just received a human body infrared signal light automatic lights, then left, automatically turns off, you can achieve the purpose of saving, the device eliminates the need for energy consumption, heavy, easy to produce heat power transformer, has a simple structure, consumable mild, stable performance, high sensitivity, versatile features. Key words: Human body sensing module; Photoresistor; Signal Processing
