太阳能广告灯箱设计与制作.doc

: .
本设计采用新能源太阳能，用太阳能电池给高亮度LED供电，利用单片机技术实现广告灯箱的光电控制、定时控制和节能控制，克服阴天时不能及时照明灯箱、天亮后不能及时关断灯箱电源的现象，避免人工控制带来的长明灯现象，以节约电能。本设计采用时、光双控电路，时控电路用DS1302芯片，光控电路采用光敏传感器，再与单片机结合实现所需功能，使广告灯箱的工作时间更加合理化，更节约能源。

Development of solar advertising light box
Abstract
This design uses the new energy solar energy, with the solar cell for the high luminance LED power supply, realizes the advertisement lamphouse photoelectric control using the monolithic integrated circuit technology, the timed control and the energy conservation control, overcomes when the cloudy day cannot illuminate promptly the lamphouse, after the dawn, cannot shut off the lamphouse power source's phenomenon promptly, avoids large oil lamp lit day and night before Buddha status phenomenon which the manual control brings, by saves the electrical energy. This design uses, the light double controls the electric circuit, when controlled the electric circuit with the DS1302 chip, the light controls the electric circuit to use the photosensitive sensor, realized again with the monolithic integrated circuit union needs the function causes the advertisement lamphouse the operating time even more rationalize, more frugal energy.
Keywords: solar battery, LED, Time control circuit, Light control circuit
