摘要:太阳能路灯有太阳能电池、蓄电池、高亮度LED、控制器等部件组成，减少噪声污染；太阳能路灯运动部件很少，基本没有噪声。太阳能辐射能是取之不尽、用之不竭的，是人类能够自由利用的能源。在世界能源短缺、环境污染日益严重的今天，充分开发利用太阳能是世界各国政府可持续发展的能源战略决策。与传统的照明工具相比，超高亮白光LED照明源体积小、重量轻、方向性好并可耐各种恶劣条件，在功耗、寿命以及环保等方面有不可比拟的优越性，再加上太阳能灯具的节能性和安装简便，所以凡有工频交流电灯具的地方，LED灯具的触角就会到达。21世纪将是以固体发光材料为核心的，即以LED为代表的新型光源、绿色照明的世纪。今后，随着各国政府的高度重视和加大投入，LED必将成为本世纪极具竞争力的新型绿色环保光源而掀起一次照明领域新的革命。

Abstract:Solar street lights are made up of solar cells,batteries,high-brightness LED,controller and other components，and they can reduce noise pollution;there is very few moving parts in solar street lights,so,there is little noise.Solar radiation is inexhaustible,and free to human.Today energy is shortage,and environmental pollution is serious in the world,so,making full use of the solar energy is the world’s governments energy strategy for sustainable development.Compared with the traditional lights ,super bright white LED light is small,light,good direction and can be resistant to harsh conditions,and in power,environmental protection and other aspects of life,solar street light has unparalleled advantages,and coupled with solar energy-saving lights and ease of installation,so that those within the place-frequency alternating current lights be used,LED lights will be reach.The 21st century will be based on the solid light-emitting material,which represented a new type of LED light source.In the future.As governments attach great importance to solar energy and increase investment in the field,LED will become very competitive in this century,and new type of green light can be gave rise to a new revolution in lighting field.
