Title:
LIGHT SOURCE SYSTEM AND LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/197582
Kind Code:
A1
Abstract:
A light source system (100), comprising: a light source mechanism (20), the light source mechanism (20) comprising a light source substrate (201) and a plurality of light-emitting diode modules (21) provided on the light source substrate (201), each light-emitting diode module (21) comprising at least two types of light-emitting diode chips; a collimating lens group (30), the collimating lens group (30) comprising a lens support (31) and collimating lens units (301) provided on the lens support (31), the collimating lens units (301) being used for collecting light emitted from the light-emitting diode modules (21); an adjusting mechanism (60), the adjusting mechanism (60) comprising a mounting support (601) and an adjusting block (606), the lens support (31) being assembled on the mounting support (601). The displacement of the collimating lens group (30) on the mounting support (601) is adjusted by means of the adjusting block (606), so that the main optical axes of light emitted from the light-emitting diode chips coincide with the central axes of the collimating lens units (301), thereby improving the light efficiency of the light source system (100).
