Solar multi-phase wired signal transmitting traffic signal lamps

The utility model discloses a poly-phase wired signal transmission traffic light powered by solar energy, which comprises a traffic signal controller electrically connected via signal cables with the input end of a signal light driver positioned on the lamppost and a power source of the traffic light. The utility model is characterized in that the power source comprises a silicon solar cell, a charge controller and a storage battery; the output end of the silicon solar cell is electrically connected with the input end of the charge controller; the output end of the charge controller is electrically connected respectively with the input end of the storage battery and the power source of the traffic light controller. The utility model has the advantages that the poly-phase wired signal transmission traffic light is powered by solar energy, so that the traffic lights can be installed in areas lack of electricity to save a large amount of investment in the construction of power lines. In addition, the solar energy is an inexhaustible, clean and pollution-free energy with low maintenance cost.
