摘  要
 
 在日益注重低碳生活的當(dāng)今社會(huì)，開發(fā)一款高效節(jié)能的智能燈具，非常有必要。智能燈具不僅僅可以用于普通的家用照明，更可以根據(jù)實(shí)際應(yīng)用場合的不同，給予適度的調(diào)整既可以適應(yīng)新的工作，如在戶外大型廣告照明以及城市景觀照明方面，具有獨(dú)到之處。
 LED光源作為近年來的新型興起的光源類型，具有低能耗，高效率的低碳經(jīng)濟(jì)理念，作為本次設(shè)計(jì)的光源比較合適，符合環(huán)保節(jié)能的設(shè)計(jì)理念。
 除此之外還使用了工業(yè)上比較盛行的Atmel公司的AVR Mega8單片機(jī)，該種單片機(jī)具有高效的短指令，數(shù)據(jù)與地址線分開的哈佛結(jié)構(gòu)。最高具有8位單片機(jī)里最高的1MIPS/1MHz的運(yùn)算速度。同時(shí)具有多種片上資源，利用這些片上資源完全可以在僅使用少量外部電路，即可完成對(duì)本范例的設(shè)計(jì)。
 同時(shí)本文結(jié)合AVR單片機(jī)還設(shè)置了紅外遙控，具有高效的人機(jī)對(duì)話接口，非常貼近日常生活的使用。

 Abstract
Increasing emphasis on low-carbon life in today's society, development of a smart   energy-efficient lighting, very necessary. Intelligent lighting not only can be used for general household lighting, but also different according to the actual applications, both for an appropriate adjustment to adapt to new work, such as large-scale outdoor advertising in urban landscape lighting and lighting with unique.
LED light source as the rise in recent years, a new light source type, with a low power,high-efficiency, low-carbon economic philosophy, as the source of this design is appropriate,environmentally friendly energy-saving design.
In addition to more widespread use of the industry, Atmel's AVR Mega8 MCU, the MCU has a kind of short and efficient instruction, data and address lines separate .
Harvard architecture.Maximum 8bit microcontroller with the highest of 1MIPS/1MHz the operation speed. Also has a variety of chip resources, use the on-chip resources can only use a small amount in the external circuit to complete the design of the sample. AVR microcontroller at the same time this paper was also set up remote control with efficient human-machine dialogue interface, very close to the daily use.
