Abstract:
A zoom unit (1) of a light engine (5), comprising at least one lens (2), at least one first reflector (3) and at least one second reflector (4), other at least one lens (2) receives a collimated beam (LI) from a light source unit (6) of the light engine (5), the collimated beam (LI) being incident on the first reflector (3) after being converged by the lens (2), and being incident on the second reflector (4) after being reflected by the first reflector (3), to produce an output beam (L4) with its beam angle changed.
