The traditional method of controlling street lamp lighting could not adjust the brightness of bulbs, while the management and maintenance had to rely on labour patrol. The combined ZigBee and GPRS technology with LED lights is an advanced controlling method for street lighting, particularly resolves the issues in monitoring and energy consumption. This paper presents a general system that incor...
