Abstract

An illumination unit includes: a substrate to which a first light-emitting element is mounted; a housing that holds the substrate; a case that is attached to the housing so as to cover the substrate and can output light of the first light-emitting element to the outside; and a light-blocking cover that is attached to the substrate, is provided so as not to cover the first light-emitting element in a direction in which light is output while surrounding the first light-emitting element, and is formed higher from a front face of the substrate than the first light-emitting element.

First claim

What is claimed is:

1. An illumination unit comprising:
a substrate to which a light-emitting element is mounted;
a housing that holds the substrate;
a case that is attached to the housing to cover the substrate, and allows light of the light-emitting element to be output to an outside; and
a light-blocking cover that is attached to the substrate, surrounds the light-emitting element and leaves the light-emitting element in a direction in which the light is output uncovered, and is formed higher from an attachment face of the substrate than the light-emitting element.

2. The illumination unit according to claim 1 , wherein
the case is formed of a light-transmissive material, and
the light-blocking cover leaves the light-emitting element uncovered in a direction in which the light is output from the case, and covers the light-emitting element in a direction in which none of the light is output from the case.

3. The illumination unit according to claim 1 , wherein
the light-blocking cover has a white surface.

4. The illumination unit according to claim 2 , wherein
the light-blocking cover has a white surface.

5. The illumination unit according to claim 1 , wherein
a plurality of the light-emitting elements are provided on the same surface of the substrate, and
the light-blocking cover individually partitions the plurality of light-emitting elements and blocks the light.

6. The illumination unit according to claim 2 , wherein
a plurality of the light-emitting elements are provided on the same surface of the substrate, and
the light-blocking cover individually partitions the plurality of light-emitting elements and blocks the light.
