ABSTRACT:
An illuminating device includes a first light source unit emitting illumination beams with a first optical axis; a second light source unit; and two reflecting elements arranged on both sides of an optical path of the first light source unit. The reflecting element arranged on the side of the second light source unit reflects the illumination beams emitted from a substantially half region on one side in an aperture plane of the parabolic reflector of the second light source unit, towards the direction along the first optical axis. The reflecting element arranged opposite to the second light source unit reflects the illumination beams emitted from a substantially half region on the other side in the aperture plane of the parabolic reflector of the second light source unit, towards the direction along the first optical axis.
