Abstract
A light source module includes a transparent conductive substrate and plural light source groups. The transparent conductive substrate includes a substrate base, plural positive electrodes, plural negative electrodes and plural gaps. The plural positive electrodes and the plural negative electrodes are installed on the substrate base. Each light source group includes plural light-emitting elements. The plural positive electrodes are separately arranged. Consequently, the resistances of the light-emitting elements are substantially equal.
