Currently, traditional lighting lamps for electricity generating streetlight system are being replaced with LED lamps because of their advantages of high efficiency and energy saving, and dimming control systems for the streetlight system are introduced to adjust the brightness of LED lamps according to the road illuminance by using photo sensors. But as time passes, the photo sensors may not work properly due to foreign substances such as snow and dust. In this paper, we has designed and implemented a lamppost controller for the photovoltac streetlight system, which controls the brightness of the lamps using its solar cells as illuminance sensors without using extra photo sensors. The implemented controller conducts effective dimming control of lamps even though the road illluminance abruptly decreases due to bad weather condition at daytime and maintains the recommended level of road illuminanation(29 luxes), which results for more than 30% of reduction in average power consumption.
