The invention relates to an intelligent street lamp control system, which comprises a lighting device, a light intensity detecting and timing circuit, a single-chip for storing software programs, a reset circuit, a timing time display circuit and a controlled silicon circuit, wherein the light intensity detecting and timing circuit is connected with the single-chip, the timing time display circuit, the controlled silicon circuit and the lighting device in turn, and the reset circuit is connected with the single-chip. The intelligent street lamp control system has the advantages of simple structure design, low cost and energy conservation. The system can be widely used for controlling street lamp light, lighting systems, neon lamps and advertising lamps, can prolong the service life of bulbs and prevent a contact switch from generating sparks, and is suitable for use on inflammable and explosive special occasions.
