Surface light-emitting unit

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.
