Zusammenfassung:	PURPOSE: An attention guidance lamp system and a construction method thereof are provided to prevent abnormal radiation caused by noise inflow, and add a shielding configuration for noise prevention when constructing the attention guidance lamp system. CONSTITUTION: An attention guidance lamp system comprises an attention guidance lamp, and a control unit. The attention guidance lamp with a brightness setting unit is connected to a ground line(410) and a power line and a signal line(420) in parallel. The attention guidance lamp also adjusts the brightness of LED according to a brightness control signal. The brightness setting unit creates PWM signal corresponding a detected analog signal for LED driving by detecting the brightness control signal pattern which is continuously provided through the power line. The control unit with a signal input unit transmits power and the brightness control signal through the power and signal lines. The signal input unit inserts the signal changed according to the brightness control signal at a certain interval to the power.
