The invention provides a traffic signal lamp emergency control system. The traffic signal lamp emergency control system comprises a solar cell panel, a storage battery, a power supply management unit, a signal control device, a circuit control device and signal lamps. The solar cell panel is electrically connected with the storage battery. The storage battery supplies power to the signal control device, the circuit control device and the signal lamps through the power supply management unit. The signal control device outputs a control signal to the circuit control circuit. The circuit control device controls the states of the signal lamps. According to the invention, the solar cell panel and the storage battery are used for storing electric energy, the storage battery supplies power to the signal lamp emergency control system when the power is off, and the solar cell panel simultaneously and continuously converts light energy into electric energy and stores the electric energy to the storage battery, so that the problem that an existing emergency power supply fails to supply power for a long time is solved; in addition, the solar energy is available everywhere, nearby power supplying is realized, long-distance transmission is not needed, and the cost of a long-distance power transmission line is avoided.
