Provided is a supporting device that enables light emitting modules to be easily installed on a ceiling for lighting and is easy to modify the light emitting modules with a simple configuration. For that purpose, a supporting device of the present invention has a large recess groove portion having a width dimension smaller than a dimension of a short side of the light emitting modules and having a length dimension larger than a dimension of a long side of the light emitting modules and a screw fixation portion provided with a threaded hole for fastening on the ceiling. On left and right interior walls of the large recess groove portion, small recess groove portions, parallel to the large recess groove portion, having a cross sectional shape approximately equal to a cross sectional shape of a peripheral end portion of the long side of the light emitting modules are formed in an arrangement facing on the left and right respectively. An interval dimension between facing groove back side portions of the respective small recess groove portion is approximately identical to a dimension of the short side of the light emitting modules. |
