1. A light source module adapted to provide illumination to a target plane, wherein the light source module comprises:
a light source having a light emitting surface;
a reflective element disposed on a transmission path of an illumination light beam emitted from the light source, wherein the illumination light beam reflected by the reflective element is configured to irradiated on the target plane, and the reflective element comprises:
a first reflective surface disposed towards the light emitting surface of the light source and being a plane; and
a second reflective surface bendably extending from the first reflective surface; and
a shell provided with an opening, wherein the light source and the reflective element are disposed in the shell, and the illumination light beam is irradiated on the target plane through the opening of the shell, wherein an included angle B is between the first reflective surface and the target plane, an included angle C is between the second reflective surface and the target plane, the included angle B is greater than the included angle C, and the included angle C is greater than or equal to 0,
wherein the second reflective surface does not overlap the light emitting surface along a normal direction of the light emitting surface of the light source.
