Abstract
An illumination system includes a first light source module and a first reflective mirror module. The first light source module includes plural first light sources for emitting plural first light beams, respectively. The first reflective mirror module includes at least one first reflective mirror, at least one first fixing structure, and at least one first adjusting mechanism. The first reflective mirror is located at a first optical axis of the plural first light sources. The at least one first fixing structure is used for fixing the first reflective mirror. The first adjusting mechanism is connected with the first fixing structure. By moving or rotating the first adjusting mechanism, a location and an angle of the first reflective mirror relative to the first optical axis are correspondingly changed, so that the first light beam is reflected by the first reflective mirror and guided along a specified optical path.
