<p>The present invention relates to a LED lighting apparatus using a light emitting diode attached to a control panel. The LED lighting apparatus according to an embodiment of the present invention includes: a circuit unit including a power supply which receives external AC power and converts the external AC power into DC power to output the DC power, an LED array unit including a first LED array composed of a plurality of LEDs and a second LED array composed of a plurality of LEDs, and an LED driver to drive the first LED array and the second LED array based on a voltage waveform of the DC power output from the power supply and a current flowing through the LED array unit; a lens cover to diffuse and irradiate light emitted from the first LED array and the second LED array to the outside; a heat sink including a circuit attaching surface provided at an upper portion thereof and in which the circuit unit is installed, a waterproof processing member into which a protrusion of the lens cover is inserted, and a heat radiator having a water wave shape. An elastic member simultaneously making contact with the protrusion and the heat sink is inserted into the waterproof processing member.</p> |
