Abstract
A light emitting device includes a substrate having an element mounting area in a principal surface thereof. The light emitting device also includes at least one light emitting element mounted in the element mounting area of the substrate. The light emitting device also includes a heat transfer member provided on the substrate. The heat transfer member has a thermal conductivity different from thermal conductivity of the substrate so as to form uneven thermal resistance distribution in the element mounting area. Thermal resistance in a heat radiation path through the substrate for release of heat emitted from the light emitting element changes with the mounting position of the light emitting element.
