Abstract
A surface light-emitting unit of the present invention is an LED module (30) for emitting light from an LED chip (6) of a light-emitting element part (1) via a light flux control section (22) of a light flux control part (2), the light flux control section (22) being fixed by a plurality of columnar sections (21) above a fixing surface of a substrate (4) on which fixing surface the light-emitting element part (1)is fixed. This provides an appropriate gap between the light-emitting element part (1) and the light flux control section (22) for heat release.
