A super power saving winker system is provided to reduce power consumption of a battery remarkably by turning on or off the light of an LED(Light Emitting Diode) at regular intervals. A winker system includes a power supply unit(10), a constant-voltage/constant-current unit(20), an illuminance detecting unit(30), a control unit(40) and an LED display unit(60). The power supply unit outputs a power source of a DC voltage. The constant-voltage/constant-current unit converts the DC voltage of the power supply unit into an output load driving voltage. The control unit controls on and off operation of the LED in accordance with an illuminance detected by the illuminance detecting unit. The LED display unit turns on and off the light of the LED at regular time intervals by the control unit. When the light is determined to be a light beam of a vehicle, the control unit maintains the LED display unit on state for a predetermined time period. |
