The present invention relates to an LED lamp device which includes a plurality of LED modules and a back cover which is selectively combined to make the LED modules form an LED surface light source of a first group. The LED module and the back cover are formed to mutually correspond to a hook protrusion part and a hook hitching part for combining or separating one LED module corresponding to a part of the LED surface light source of the first group with or from the back cover by a hook combination and separation method when one LED module is repaired or replaced. Thereby, the present invention facilitates replacement and repair operations and reduces costs. |
