摘  要
 
 在日益注重低碳生活的当今社会，开发一款高效节能的智能灯具，非常有必要。智能灯具不仅仅可以用于普通的家用照明，更可以根据实际应用场合的不同，给予适度的调整既可以适应新的工作，如在户外大型广告照明以及城市景观照明方面，具有独到之处。
 LED光源作为近年来的新型兴起的光源类型，具有低能耗，高效率的低碳经济理念，作为本次设计的光源比较合适，符合环保节能的设计理念。
 除此之外还使用了工业上比较盛行的Atmel公司的AVR Mega8单片机，该种单片机具有高效的短指令，数据与地址线分开的哈佛结构。最高具有8位单片机里最高的1MIPS/1MHz的运算速度。同时具有多种片上资源，利用这些片上资源完全可以在仅使用少量外部电路，即可完成对本范例的设计。
 同时本文结合AVR单片机还设置了红外遥控，具有高效的人机对话接口，非常贴近日常生活的使用。

 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.
 Keywords: LED light source、Atmel AVR mega8、infrared remote control decoding
