The present invention relates to a lighting device with an enhanced heat dissipation function, and more specifically, to a lighting device with an enhanced heat dissipation function, in which a lighting member and a control member are provided to be thermally conductive to a body member, which allows heat to be easily dissipated by heat sink fins provided at an upper portion of the body member, and external air to be easily introduced through air passages between the heat sink fins, and which generates a vortex of the external air inside a socket member, which is introduced through the air passages, by vortex generating holes and rotary pieces, so as to dissipate the heat through discharge holes, thereby being excellent at heat dissipation of a column-shaped or disc-shaped lighting device. The lighting device with the enhanced heat dissipation function comprises: the body member which includes an opening at the bottom, multiple heat sink fins vertically protruding in a radial form from the top surface, and air passages between the heat sink fins to allow the external air to be able to move; the lighting member which is thermally conductive to the body member and radiates the light in a direction of the opening; a cover member which is provided beneath the body member to prevent foreign substances from being moving into the body member and protects the lighting member against external environments; the control member which is thermally conductive to the body member, applies electric power to the lighting member, and enables the external air introduced into the body member to generate the vortex; and the socket member which is provided above the body member to cover the exterior of the control member and dissipates the heat generated from the lighting member and the control member by expanding the vortex of the external air generated by the control member, so that the external air swirls more widely.
