STANDBY POWER INTERCEPTION METHOD USED LED SENSOR LAMP AND LED SENSOR LAMP HAVE STANDBY POWER INTERCEPTION FUNCTION

摘要

PURPOSE: An LED(Light Emitting Diode) sensor lamp and a standby power blocking method using the same are provided to reduce power consumption by applying the power to a second power supply source according to a sensing signal of a sensor. CONSTITUTION: A controller(10) processes a signal of a sensor unit(20). A first power supply unit(30) supplies the power to a controller. A power input unit(40) supplies the external power to the first power supply unit. A switch unit(50) receives a control signal of a controller and transmits an operation signal to a second power supply unit(60). If the operation of a user is not sensed by the sensor unit, the switch unit blocks the second power supply unit. If the operation of the user is sensed by the sensor unit, the switching unit applies the power to the second power supply unit for operating an LED source(70).
