A light-source module including a light-source holder, a light source, a collimator lens holder, a collimator lens, a fasten member and an elastic member is suitable for being disposed in a housing. The light-source holder having a convex portion engaged with a concave portion of the housing is adapted to rotate about an axis. The light source disposed in the light-source holder emits a light beam along a beam path. The collimator lens is disposed in the collimator lens holder disposed in the light source holder on the beam path and a distance is maintained between the light source and the collimator lens. When fastened into a positioning hole of the housing, the fasten member pushes the light-source holder to rotate about the axis and the light-source holder presses the elastic member leaned against the light-source holder. |
