摘 要 太阳辐射能实际上是地球上最主要的能量源泉。自然界中的燃料能、风能、水能等皆来源于太阳能。太阳辐射能与常规能源及核能相比有广泛性、清洁性、分散性、间歇性、地区性、永久性的特点。全球性的能源短缺、环境污染、气候变暖等问题正日益困扰着人类社会，“寻求绿 色替代能源，实现可持续发展”已成为世界各国面临的共同课题。太阳能光伏发电不排放 CO2 和 SO2，也没有常规发电的噪音、固体废物和其他污染，是当前最重要的可再生能 源技术之一。因此，太阳能是未来新能源体系中极其重要的战略能源，也得到了世界各国的强烈重视。太阳能既是一次能源，又是可再生能源，可发直接转化利用。通过转换装置把太阳辐射能转换成热能利用的属于太阳能热利用技术，再利用热能进行发电的称为太阳能热发电；通过转换装置把太阳辐射能转换成电能利用的属于太阳能光发电技术。随着太阳能发电技术的不断发展，太阳能路灯以环保、节能、安全等优 势成为城市道路照明行业的新宠，市场潜力巨大。在不同地区，诸如城市或乡村，对 太阳能路灯照明密度的要求不同，本论文主要通过研究太阳能路灯、太阳能电池、蓄电池、控制器、LED灯源等各器件的工作原理及其各自的基本特性，根据不同的要求从实用性和经济性方面考虑选择出适合本地区需求的相应容量的太阳能光伏电池、蓄电池、充放电控制器、LED灯源等配置，实现太阳能路灯照明系统的整体设计 关键词 太阳能路灯,光伏电池,蓄电池,充放电控制器,LED光源 Abstract Solar radiation is actually the most important source of energy on earth. The nature of the fuel energy, wind energy, hydro mused from solar energy. Solar radiation compared with conventional energy sources and nuclear energy has broad, clean, decentralized nature, intermittent, regional, permanent features. Global energy shortages, environmental pollution, global warming and other issues are increasingly plagued human society seeks, green alternative energy to achieve sustainable development has become a common issue facing the world. Solar photovoltaic power generation does not emit CO2 and SO2, there is no conventional power noise, solid waste and other pollution, is the most important renewable energy technologies. Therefore, solar energy is the future of new energy system is extremely important strategic energy, has also been a strong emphasis on countries in the world. Both a solar energy is renewable energy, can be sent directly into use. By converting means to convert solar radiation energy use is solar thermal technology, and then generate electricity using heat energy called solar thermal power; through the conversion means to convert solar radiation into electrical energy use is solar power technology. With the continuous development of solar power technology, solar lights to environmental protection, energy, security and other advantages t
