LIGHT SOURCE SYSTEM AND LIGHT-EMITTING APPARATUS

Title:

LIGHT SOURCE SYSTEM AND LIGHT-EMITTING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2020/024610

Kind Code:

A1

Abstract:

Disclosed are a light source system (100) and a light-emitting apparatus. The light source system (100) comprises: a first light source (110), a light conversion element (140), a heat dissipation device (150) and a light homogenizing device (160), wherein the first light source (110) is used for emitting first light; the light conversion element (140) is used for receiving the first light and converting some of the first light into fluorescence, and the light conversion element (140) is fixed to a first surface of the heat dissipation device (150); and the light homogenizing device (160) comprises a polygonal tapered rod. The polygonal tapered rod comprises: a polygonal light entry face (161) parallel to a light exiting face of the light conversion element (140); a light exiting face (162) having dimensions different from that of the light entry surface (161); and a connecting face (163) perpendicularly connected between the light entry face (161) and the light exiting face (162), the connecting face (163) being fixed to a second surface of the heat dissipation device (150). The connecting face (163) is perpendicularly connected between the light entry face (161) and the light exiting face (162) of the light homogenizing device (160), thereby facilitating the improvement in assembly convenience and precision, processing easiness and production efficiency of the light homogenizing device (160).
