摘  要
 隨著社會經濟的發展和人民生活水平的提高，對能源的需求量不斷增長 石化能源資源的有限性，以及他們在燃燒過程中對全球氣候和環境所產生的影響日益為人們所關注。從資源、環境、社會發展的需求看，開發和利用新能源和再生能源是必然的趨勢。隨著我國經濟的快速增長，能源需求大幅度增加，特別是用電緊張進一步加劇，尋求新能源和再生能源迫在眉捷。
 太陽能是一種非常重要的可再生能源太陽能作為地球上真正取之不盡的清潔能源，將是2l世紀最理想的綠色新能源，其利用的有效途徑便是利用光伏發電技術將太陽能轉化為電能。
 本文介紹的太陽能蓄電裝置，由充放電模塊、太陽能電池模塊、光控電路、瞬時光照保護電路、LED閃爍電路等組成。該系統實現了陽能為能源，鉛酸蓄電池為蓄能部件和電路工作電源，設置在夜間有事故隱患的路段，LED不間斷地閃爍，白天可關閉。并且，該系統充分考慮了系統實際運行環境，提高了電路穩定性。例如，該系統中設計的充放電保護裝置有效地防止了過充電和過放電，瞬時光照保護電路避免了夜間光源干擾。

Abstract
Along with the socio-economic development and the improvement of living standards, the energy of the growing demand for petrochemical limited energy resources, and their combustion processes in the global climate and environmental impact of growing concern for people. From resources, environment, social development needs, the development and use of new and renewable sources of energy is an inevitable trend. As China's rapid economic growth, a substantial increase in demand for energy, particularly electricity is further exacerbated tensions and seeks new and renewable sources of energy to force in the eyebrow.
Solar is a very important renewable energy sources as solar energy on the planet truly inexhaustible supply of clean energy, 21century will be the best new green energy, its use is an effective way to use solar photovoltaic power generation technology will transform Electricity.
This paper describes the installation of solar Reserve Power, by charging and discharging modules, solar cell modules, optical control circuit, instantaneous light protection circuit, LED flashing circuit components. The system can be realized-to-energy, lead-acid battery for energy storage components and circuit power, set up in the evening section of a hidden causes of accidents, LED flashes uninterrupted during the day to close. In addition, the system fully considered the actual operation of the system environment and enhance the stability of the circuit. For example, the system design of the charge and discharge protection devices to effectively prevent the charge and have a discharge and transient protection circuit illumination at night to avoid the interference source.
