摘要:
A light emitting device includes a light emitting element, a substrate with a flat mounting surface for mounting the light emitting element thereon, a sealing part for the light emitting element on the mounting surface of the substrate. The sealing part is formed of glass including a phosphor to be excited by light emitted from the light emitting element to radiate a wavelength conversion light. The sealing part is shaped like a rectangular solid wherein a lateral length is defined as a distance between a center of a bottom surface of the sealing part bonded to the mounting surface and a side face perpendicular to the mounting surface, a vertical length is defined as a distance between the mounting surface and a top surface of the sealing part, and at least one of the lateral length is longer than the vertical length. The device further includes a transparent member formed on the top surface of the sealing part. The transparent member includes the phosphor at a concentration higher than the sealing part.
