PURPOSE: An LED lamp provides not only convenience but also beauty by sensing sound or wind without any artificial on and off operation and partially or completely operating a plurality of LEDs in on and off mode according to the sensing degree. CONSTITUTION: A battery(14) accumulates electricity generated in a solar battery(13). A DC-DC converter(25) changes voltages accumulated in the battery into DC. An LED(11) emits light by receiving an DC electricity converted in the DC-DC converter. A sensor(30) senses the driving elements of an LED. A control circuit(50) processes the signals sensed in the sensor and drives an LED according to the processing results. |
