The present invention relates to an apparatus for regulating a focus of an LED lighting device. More particularly, the present invention relates to an LED lighting device with a focus regulating function to implement uniform illumination on a bottom surface or an irradiating surface of light by directly rotating a PCB, and regulating a focus by spreading or concentrating light emitted from an LED. The LED lighting device with a focus regulating function capable of regulating a focus by spreading or concentrating light emitted from an LED, includes a base frame (10) including a central shaft (11) having a cylindrical shape by coupling and fixing an LED PCB board (20) with a focus regulating handle (30) and a circular lower plate (12) provided at a lower end of the central shaft (11); an LED PCB plate (20) horizontally disposed at the lower plate (12) of the base frame (10), attached to the focus regulating handle (30), formed therein with a hinge shaft (23) to control an angle, and to output a light source to a desired position; and the focus control handle (30) vertically coupled with the central shaft (11) of the base frame (10) so that a worker may vertically move the focus control handle (30) by a hand. |
