Zusammenfassung:	The invention relates to a focusing unit (1) of a light engine (5). The focusing unit (1) comprises at least one lens (2), at least one first reflector (3) and at least one second reflector (4) arranged sequentially; at least one lens (2) is used for receiving parallel beams (L1) from a light source unit (6) of the light engine (5); and the parallel beams (L1) are converged through the lens (2), transmitted to the first reflector (3), reflected by the first reflector (3) and then transmitted to the second reflector (4) to produce output beams (L5) with adjusted output angles. Moreover, the invention also relates to the light engine with the focusing unit and an illumination device. The light engine with the focusing unit can beneficially replace a halogen lamp in the common illumination device; and on the premise that the outline of the conventional illumination device is not changed, and the effect of a shadowless lamp is achieved.
