Abstract
Provided is a small-sized light emitting apparatus having a configuration capable of uniformly cooling multiple LEDs. A light emitting apparatus, which emits linear light, includes: a light source unit which has multiple light sources that are disposed on a surface of a substrate in parallel in a first direction; a heat dissipation unit which has multiple heat radiation fins formed in the first direction, and is thermally coupled to a rear side of the substrate; a partition plate which forms a first air channel surrounding the multiple heat radiation fins; a housing which forms a second air channel between the housing and the partition plate; and a cooling fan which receives air from the outside, guides the air to the second air channel, and forms an airflow in the first direction.
