Abstract
A light emitting device includes: a package including upper and lower portions, and one or more lateral portions including a first lateral portion having a light-transmitting portion, the package having a closed space; a first light-emitting element having an upper surface, configured to have one or more emission points on the upper surface, and disposed on a mounting surface of the lower portion; and a reflecting part having a first reflection surface within the closed space to reflect light emitted upward from the emission points. Light reflected from the first reflection surface is transmitted through the light-transmitting portion. In a direction normal to the mounting surface, a first distance between a lower surface of the upper portion and the mounting surface is equal to or greater than 1.5 times a second distance between the upper surface of the first light-emitting element and a midpoint of the first reflection surface.
