摘 要
本项目针对台灯的节电和使用的方便性进行创新设计与研究,以单片机为核心,综合运用热释电红外、光检测等技术,设计制作出智能型多功能LED台灯。该台灯具有自动开、关,多级调光等功能,实现对台灯用电情况和亮度调节的智能控制。而对光源的选取,我们选用了5mm的草帽型LED作为光源。LED发光器件是冷光源,光效高,工作电压低,而且能耗低,可控制好、无辐射。LED寿命可达10万小时,是荧光灯的10倍,白炽灯的100倍。随着能源紧缺、电价越来越高、环保要求及LED的光效的提高,用LED替代现在台灯普遍使用的白炽灯或荧光灯,环保无污染。

Abstract
The project for energy-saving lamp and ease of use for innovative design and research to the microcontroller as the core, the integrated use of pyroelectric infrared ray detection technology, intelligent design a multi-LED lamp. The lamp has an automatic open and close, multi-level dimming and other functions, to achieve the lamp brightness adjustment of electricity consumption and intelligent control. The selection of the light source, we use the hat of a 5mm LED as light sources. LED light-emitting device is a cold light source, high luminous efficiency, low voltage and low energy consumption, control, and no radiation. LED life of up to 100,000 hours, is 10 times the fluorescent, incandescent 100 times. With energy shortages, rising electricity prices, environmental requirements and improve the efficiency of LED light, LED replacement lamps are now commonly used incandescent or fluorescent lamps, environmental pollution.
