The present invention provides a plurality of ground walking traffic lights to which a control signal and a voltage-controlled power supply are applied, in each of the ground walking traffic lights, the voltage-controlled power supply is converted into a constant-current power supply, and the constant-current power supply is applied to an LED array in accordance with the control signal. Thus, the present invention can prevent a decrease in brightness of the ground walking traffic lights as the distance from the controller increases, and can maintain the constant lighting time of the plurality of ground walking traffic lights so that the visibility of the ground walking traffic lights remains constant even if the width of the pedestrian crosswalk increases.

    本发明提供多个地面式步行信号机,其中,施加有控制信号和电压控制电源,在每个地面式步行信号机中,电压控制电源被转换成恒流电源,所述恒流电源根据所述控制信号被施加到LED阵列。由此,本发明能够防止地面式步行信号机随着与控制器的距离增加而亮度降低,并且保持所述多个地面式步行信号机的恒定亮灯时间,使得即使人行横道的宽度增加,地面式步行信号机的可视性也保持恒定。
