Document Type and Number:
WIPO Patent Application WO/2017/101773
Kind Code:
A1
Abstract:
Disclosed is a light source system, comprising a first lighting subsystem, a light source shaping subsystem, and a second lighting subsystem located between the first lighting subsystem and the light source shaping subsystem. The first lighting subsystem comprises: a laser light source array (11); a wavelength conversion device (12) provided on a light exit path of the laser light source array (11), the wavelength conversion device (12) comprising at least one wavelength conversion zone (121). The second lighting subsystem comprises: a first LED array (21) provided on a light exit path of the wavelength conversion device (12), a light-emitting surface of the first LED array (21) facing away from the wavelength conversion device (12), and the first LED array (21) comprising a light through hole (211) coinciding with the light exit path of the wavelength conversion device (12). The light source shaping subsystem comprises: an integral lens group (31) provided on a light exit path of the first LED array (21); a first condensing lens (32) provided on one side of the integral lens group (31), facing away from the first LED array (21); a movable condensing device (33) provided on the side of the first condensing lens (32) facing away from the integral lens group (31), the movable condensing device (33) being able to move into or move out of a light exit path of the first condensing lens (32), improving the light flux output, and switching the size of a light spot of the light emitted from the light source system. Further disclosed is an illumination system comprising such a light source system.
