Document Type and Number:
WIPO Patent Application WO/2021/010461
Kind Code:
A1
Abstract:
A light-emitting module (12) has: a first light source (20) that emits light for forming a first light distribution pattern and comprises at least one first semiconductor light-emitting element (18); a second light source (24) that emits light for forming a second light distribution pattern and comprises at least one second semiconductor light-emitting element (22); a lighting control circuit (26) for performing lighting control of the semiconductor light-emitting elements; and a heat-dissipation plate (28) having a first element mounting surface (28a) on which the first semiconductor light-emitting element (18) can be mounted, a second element mounting surface (28b) on which the second semiconductor light-emitting element (22) can be mounted, and a circuit mounting surface (28c) on which the lighting control circuit (26) can be mounted. The circuit mounting surface (28c) is formed so as to be orthogonal or inclined with respect to the first element mounting surface (28a), and the first element mounting surface (28a) is a surface different from the second element mounting surface (28b).
