Abstract

The present invention discloses an LED lighting device, which provides uniform and efficient lighting, and has parts of such that affected areas can be easily replaced in case of a partial defect. The LED lighting device comprises: a support frame; a plurality of lighting units having a unit base, which is coupled to the support frame and adapted to attach to and detach from the support frame, and which supports a plurality of LED elements, and a reflection unit having reflecting surfaces in a shape that extends from the unit base along the light path of the LED elements; and a diffusion unit, which is positioned at the front of and horizontally to the light path of the LED elements in order to diffuse emitted light.
