The utility model discloses a traffic light having the effective dust-proof function, which comprises a horizontally and transversely arranged cylindrical housing. The left side surface of the housing is provided with an LED lamp bank vertically arranged side by side. The left side of the upper end of the housing is provided with a horizontal front sunshade. The lower side surface of the front sunshade is provided with a vertically and obliquely arranged dust shield. The front sunshade, on the left side of the obliquely arranged dust shield, is provided with a vertical communicating pipe. The lower end of the communicating pipe is provided with an obliquely arranged blowing port. The lower end of the blowing port is oriented towards the left side surface of the upper part of the obliquely arranged dust shield. The upper end of the communicating pipe is communicated with the vertical communicating pipe through a swivel. The right side of the communicating pipe is provided with a horizontal bell mouth. The left side of the communicating pipe is connected with a guiding tailgate through a connecting rod. The front sunshade is provided with a rain hood. By means of the blowing port and the obliquely arranged dust shield, dusts can be effectively removed, so that the display of the traffic light is ensured to be accurate and clear. Meanwhile, dusts are removed by the natural wind, so that the energy is saved. Therefore, the dust-removing operation is stable and efficient.
