PURPOSE: A lighting device is provided to prevent the deterioration of luminous intensity by preventing contaminants or dust from being attached to the surface of the lighting device. CONSTITUTION: A ground(14) is arranged on the upper surface of a support frame(10). An aluminum case(16) is arranged on one side of the ground. A circuit board is mounted on the inner surface of the aluminum case. A plurality of LEDs(20) are electrically connected to the circuit board. A synthetic resin(22) is coated on the inner surface of the aluminum case. A conductive polymer compound coating layer(24) is coated on the upper surface of the synthetic resin. A conductive tape layer(26) is attached to the upper surface of the conductive polymer compound coating layer. |
