Title:
SEMICONDUCTOR LAMP
Document Type and Number:
WIPO Patent Application WO/2018/066092
Kind Code:
A1
Abstract:
This semiconductor lamp (1) is provided with: a plurality of first light source units disposed at intervals in the circumferential direction around a lamp axis (AX), and a plurality of second light source units located further toward the distal side than the first light source units and disposed at intervals in the circumferential direction. The first light source units are each provided with a first heat sink part (3) and a first semiconductor light source (4a). The second light source units are each provided with a second heat sink part (5) and a first semiconductor light source (6a). The outer dimension of the semiconductor lamp (1) in the direction perpendicular to the lamp axis (AX) increases at least partially in the distal direction at the location where the plurality of first light source units are disposed, and increases at least partially in the proximal direction at the location where the plurality of second light source units are disposed.
