TRAFFIC SIGNAL LAMP CAPABLE OF INTELLIGENTLY ADJUSTING BRIGHTNESS

The present disclosure discloses a traffic signal lamp capable of intelligently adjusting brightness, which includes a light detecting unit; a visibility detecting unit; a 5 signal lamp and an intelligent adjusting device; the light detecting unit; the visibility detecting unit and the signal lamp are all electrically connected with the intelligent adjusting device; the light detecting unit is used for detecting backlight intensity of the signal lamp and sending a backlight intensity signal to the intelligent adjusting device; the visibility detecting unit is used for detecting visibility of an environment where the 10 signal lamp is located and sending a visibility signal to the intelligent adjusting device; and the intelligent adjusting device is used for adjusting a brightness of the signal lamp according to the backlight intensity signal and the visibility signal. The present disclosure solves the problems that a driver is difficult to distinguish the state of the signal lamp or observe a road condition due to that the brightness of the traffic signal 15 lamp cannot be correspondingly adjusted when the backlight intensity is too high or too low; and the brightness is not enough to play a sufficient warning effect in the case of low visibility.
