Title:
LIGHT SOURCE UNIT FOR VEHICLE LAMP, VEHICLE LAMP
Document Type and Number:
WIPO Patent Application WO/2022/004472
Kind Code:
A1
Abstract:
The present invention further improves the light emission efficiency of a semiconductor light-emitting element. In the present invention, a mounting member (2), a substrate (3), two semiconductor light-emitting elements (LED1, LED2), and three terminals (T1, T2, T3) are configured as a socket (S), which is an integral structure. Meanwhile, a control circuit (4) is configured separately from the socket (S). As a result, in this present invention, because the control circuit (4) is set away from the substrate (3) of the socket (S), it becomes possible to further improve the light emission efficiency of the semiconductor light-emitting elements (LED1, LED2).
