<p>The present invention relates to an LED sensor lamp capable of performing a crime prevention lighting using lower power, capable of turning on an LED lamp with set illumination by supplying a current to the LED lamp by an electronic transformer which generates oscillation with a weak current corresponding to a resistor when a sensor is not operated, by differentially supplying an AC voltage in case of passing the AC voltage applied to a bridge rectifier of the electronic transformer through only the resistor and through the resistor and a triac by the operation of the sensor, by serially connecting the triac to the bridge rectifier of the electronic transformer connected to the LED lamp and connecting the resistor to the triac in parallel.</p> |
