The present invention relates to an LED lighting structure with an improved structure which is capable of giving external aesthetics because the LED lighting structure comprises a quadrangular frame, maintaining a gap between an LED lamp and a lens member, increasing thermal conduction performance by making a thermally conductive circuit board tightly come into contact with a heat radiation frame and minimizing a light loss by preventing scattering of light radiated from the LED lamp. The LED lighting structure according to the present invention comprises: the heat radiation frame which has at least one holding groove formed on one surface and a plurality of heat radiation plates separately formed on the other surface; the circuit board made of a thermally conductive material which is placed on the bottom surface of the holding groove of the heat radiation frame and has the LED lamps separately arranged on one surface thereof; and the lens member which is detachably combined in the holding groove of the heat radiation frame with a fastening means and makes the circuit board tightly come into contact with the bottom surface of the holding groove because the lower surface end of the lens member comes in contact with the upper surface of the circuit board and a support extends to press the circuit board from an upper part to a lower part. |
