Title:
SEMICONDUCTOR LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/259903
Kind Code:
A1
Abstract:
A semiconductor light-emitting device (10) comprises a stem (20), a light-emitting module (30), and an enclosure member (40). The stem (20) includes an electrically conductive base (22) and an electrically conductive heatsink (24) vertically provided on the base (22) and on which the light-emitting module (30) is disposed. The enclosure member (40) is provided on the base (22) so as to surround the light-emitting module (30) and the heatsink (24). The light-emitting module (30) includes a substrate (50) disposed on the heatsink (24), a light-emitting element (60) mounted on the substrate (50), and a light-emitting element drive circuit (70) mounted on the substrate (50). The light-emitting element drive circuit (70) includes a transistor (80) for driving the light-emitting element (60). The transistor (80) is mounted on the substrate (50) as a vertical MOSFET.
