Small light-source module and light-source unit

A small light-source module (10) has a module body (11) having a small single-point light source (18) with a limited light-emitting angle mounted thereto, and a reflective surface (12) provided on the module body (11). The light axis (4) of the light source (18) is tilted with respect to the reflective surface (12), so as to create a substantially fan-shape projected light region on the reflective surface. The outer contour of the reflective surface (12) is also substantially fan-shaped, and the reflective surface has a reflective pattern (13) for reflecting light emitted form the small single-point light source (18) as parallel light.
