Design Of Solar Interior Lighting System Based On K60

The development of industry changed human life, especially the development of the electric power production makes our life more convenient, but the development spent a lot of non-renewable resources, resulting in a shortage of energy.Energy consumption at the same time,also can cause a lot of environmental problems.Therefore, in the face of the shortage of energy and environmental problems, we need to pay attention to the development and application of new energy and low carbon and environmental protection.New energy refers to the other kind of energy which is different from the traditional energy, such as solar energy. Solar energy is favored by the people because of its widespread distribution and green safe renewable.Solar energy refers to the heat radiation of solar, which has become an important part of human use of energy, and continue to develop. The use of solar energy has two ways which is divided into thermal conversion and photoelectric conversion,and solar power is a good choice in the emerging renewable energy.How to get the solar energy application to the People's Daily life is a worldwide problem need to solve.The current household lighting system is still using the traditional pattern, and the main way of power generation in our country is the use of thermal power, if we can use solar power instead of the traditional power supply mode to reform our daily lighting system, which will save a lot of fossil resources. This topic has designed a set of solar home lighting system in order to solve the above problems,solar energy was used directly to the People's Daily life. The design of this thesis includes three main parts,solar energy to battery charging,K60 control system and control system with LED light. Using lead batteries to store the power which is generated by solar panels(100W)to supply the LED light. Use the Cortex-M4 kernel ARM K60 of Freescale Semiconductor production as the main control chip control system to complete the whole system.At the same time display the lead battery voltage with OLED, and indoor lighting lamps use bright LED light(DC 12V/7W).The system fully uses the solar energy which is not plugged in and no need of rectifier and inverter, lit LED lights directly, and can automatically control the bright lights, lights turn off when people go, save energy, does not produce carbon dioxide, dust and other atmospheric pollutants, less contamination to the environment. There is no use of indoor lighting system using battery board according to the data. Its advanced technology,innovative design and greens environmental protection determine that the product market prospect is very broad, and it has great development space.
