PURPOSE: An LED(Light Emitting Diode) lamp is provided to prevent the decrease of illumination by arranging a plurality of LEDs of an LED array with a matrix shape. CONSTITUTION: A rectifying circuit unit(200) full-wave-rectifies a commercial power source. An LED unit(210) is comprised of first to third LED arrays. A driving unit(220) includes first to third switching circuits. The first switching circuit is connected to an anode of a first LED array. The second switching circuit is connected to the anode of a second LED array. The third switching circuit is connected to the anode of the third LED array. A controller(230) controls the on and off of the first to third switching circuits of the driving unit. |
