| 摘要 |
The present invention relates to an LED lamp comprising a lighting module having LED devices; a motion sensor sensing a motion of a target object; and a controller calculating a variation of a sensing value of the motion sensor and turning on the lighting module when the variation of the sensing value is within a registered reference variation range. Also, the LED lamp comprises: a lighting module having LED devices; a motion sensor sensing a motion of a target object; and a controller turning on the lighting module based on a sensing result of the motion sensor, wherein the motion sensor includes sensor windows having different sensing ranges and the sensor windows are formed to have different sensing directions, respectively. In the LED lamp, sensing performance of the motion sensor is increased in the lamp operating according to a sensing result of the motion sensor, and the lamp itself can adjust a sensing direction of the motion sensor. |
