Title:
LIGHT-EMITTING MODULE AND LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2010250962
Kind Code:
A
Abstract:

To provide a light-emitting module capable of maintaining heat radiation performance in spite of directly mounting on a ceiling by making heat generated at a light-emitting element conduct at an irradiation direction side of light, and a lighting fixture.

The light-emitting module includes: the light-emitting element 3, a substrate 1 mounting the light-emitting element 3 at one face side and forming a heat conduction section 2 on the surface of one face side; a light-distributing control member 4 thermally combined with the heat conduction section 2 of the substrate 1 and controlling light-distribution of light irradiated from the light-emitting element 3; a light-transmitting cover 5 arranged so as to permeate light irradiated from the light-emitting element 3 to the outside and thermally combined with the light-distributing control member 4 so as to set a temperature difference between the outer surface and a mounted section 6 of the light-emitting element 3 at 15 K or below when the light-emitting element 3 light-emits.
