LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting device capable of changing light distribution with a simple structure.SOLUTION: A light-emitting device 1 includes a module support 4 that has in a side surface part an attachment surface (a first attachment surface 4a, a second attachment surface 4b and a third attachment surface 4c) to which plural light source modules 2 are attached. The attachment surface includes the plural first attachment surfaces 4a, and the plural second attachment surfaces 4b whose angle to a device central axis is different from that of the first attachment surface 4a.
