<p>PURPOSE: A lighting device is provided to control the on/off state of a lamp by detecting the distance from an object through a sensor. CONSTITUTION: A lighting device comprises a controller(10), a lamp(110), and a power supply part. The controller includes a proximity sensor(1) and a transceiver(2). The proximity sensor senses the approach of an object(1000). When the proximity sensor senses the approach of the object, the controller turns on the lamp. When the object is outside a predetermined distance, the controller turns off the lamp. The power supply part supplies power to the controller and the lamp.</p> |
