A UV coating composition for LED color conversion including: 25 wt % to 97 wt % of a UV curable resin; and 3 wt % to 75 wt % of a phosphor. The composition enables emission of white light using only a white LED lens or a light guide plate without affecting a blue, violet or UV LED, thereby eliminating a need for a white LED. Further, users of a LED including the composition can perform direct and easy adjustment of the intensity of white light to obtain a desired intensity by replacing a conventional LED lens. The LED lens provides soft and comfortable lighting which effectively reduces glare caused by high brightness white LED lighting. Moreover, the composition slows deterioration of a lighting device and makes possible a light guide plate having a simple and thin structure.
