Abstract
A light emitting device includes: a substrate; a first light emitting element and a second light emitting element that are mounted above the substrate; and a heat transfer pattern that is formed on the substrate. A rate of decrease in light output with respect to a temperature increase is greater for the second light emitting element than for the first light emitting element. The second light emitting element is mounted above the substrate via the heat transfer pattern, and the first light emitting element is mounted above the substrate without the heat transfer pattern.
