摘要
    太阳能发电在光生电方面有很广阔的应用，它是利用光生伏特效应把光能转换成电能的一种发电方式。本设计就是利用太阳发电的原理，设计出的一款新颖的照明装置，利用光伏电池板，蓄电池，LED灯，对其抗干扰性、自动化控制及传感方式而改进的。
首先，这个设计是采用了太阳能电池作为能源，以达到环保节能的目的。太阳能电池的型号有多种，但在这里我们要选择的型号得根据负载的用量来定，这部分内容在以下会具体介绍。采用小巧灵活新型设计，它的信号经过单片机放大处理后就能够与PC机通信，所以此处的单片机将会使用89s51单片机，整个设计都会在它的软件控制下工作。
系统内部设置存有蓄电池，为了保证在阴雨天气下，蓄电池内有存储的电能来给设备供电。灯源部分用了LED灯，对LED灯的选择也需要根据本身的情况来定，以下部分将会讨论灯的选型。还得考虑到控制部分，控制部分由时钟控制型，光控制型，经纬型控制，可以选择最优型的负载经纬型。
    负载经纬型，采用单片机原理，白天自动关闭，晚上自动开启，结合了钟控和光控的缺乏的优点，既能避免干扰光线影响其输出性能，有能根据全年季节性的变化，自动调节开关的时间，真正达到全自动。综上所述，经纬型成为了最众人瞩目的焦点，目前正在使用中，价格很高，浪费了不必要的成本费，但是它的优点及其重要。
 因此，居于以上的优点，本设计中采取负载经纬型作为控制器。

Abstract
    Solar power generation has a very broad application in the light-electric baker. It is the use of PV effect to convert light energy into electrical energy of a power generation. This design is the use of the solar power to design a novellighting device.Use the solar panels,storage battery,LED lamp,Improvement on theequipment of its anti-interference, automatic control and sensing methods, and about the styling for LED lights to innovate.
    Firstly,the design uses a flexible model design, it uses solar energy as energy to protect the environment .Solar energy battery has many styles ,but we need decide it by the load .We will introduce it below the article . At the same time ,it signals processed by MCU, convenient communication with PC. The processor uses 51 series single chip AT89S51, the system is working under the control of the software.
    Within the system is provided with a battery, used to ensure that the rainyweather, the energy stored within the battery to supply power.Lamp source havefour selections:clock control,photo control,weft control ,then,please choose the best weft control.
    The weft control is based on 51 series single chip AT89S51.When the skybecome dark ,the lawn lamp will turn on ,the same to the light.It has clock and photo’s advantages.So,he weft control is popular andits price is expensive .However ,it is good for us about weft control’s advantages.
    These introduce is very brief,if you want to knowledge detailed,please read the blow.

Keywords: Solar energy battery；Controller；Lawn lamp
