LIGHT SOURCE UNIT AND IMAGE PROJECTION APPARATUS INCLUDING LIGHT SOURCE UNIT

摘要

A light source unit includes a light emitting element supporter to support a plurality of light emitting elements disposed with a dispersed pattern in a two-dimensional direction as a light emitting element assembly, and light emitted from the light emitting element assembly exits to a target; a light return member disposed at a position facing a light emitting side of the light emitting element assembly while setting a space with the light emitting element supporter, the light return member returning light emitted from the light emitting element assembly toward at an inner side of two dimensional direction of the light emitting element assembly, and a flow path of the cooling air to pass through cooling air supplied from an air supply unit into the space.

1. A light source unit, comprising:
a plurality of light emitting elements disposed with a dispersed pattern in a two-dimensional direction to together form a light emitting element assembly, the light emitting element assembly being configured to emit light to a target; a light emitting element supporter to support the plurality of light emitting elements of the light emitting element assembly; and a light return member disposed at a position facing a light emitting side of the light emitting element assembly while setting a space with the light emitting element supporter, and configured to return light emitted from the light emitting element assembly toward at an inner side of two dimensional direction of the light emitting element assembly, wherein cooling air supplied from an air supply unit passes through a flow path into the space formed by the light return member with the light emitting element supporter.
