Light source module mainly comprises a reflector and a lamp is provided. The reflector comprises a light output section, and a portion of the reflector corresponding to the light output section comprises at least one protrusion. The lamp is disposed in the reflector, and the light emitted by the lamp is reflected onto other portions of the reflector via the protrusions of the reflector, and then output from the light output section. Further, a portion of the reflector corresponding to the light output section is designed as a curve F, and a portion of the reflector adjacent to the light output section is designed as a reflective surface S. The curve F is connected to the reflective surface S, and the curve F=∫dFdS=∫(ax+by+c)dS, wherein dF is a differential plane that constructs the curve F, dS is a differential plane that constructs the reflective surface S, and (a, b) is a normal vector of the differential plane dF. With such design, the light source utilization efficiency is effectively improved.
