In a first aspect of the present invention, a light-emitting diode includes a light-emitting element with a p-n junction, a first light-transmitting member including a phosphor and sealing the light-emitting element, and first and second covers disposed on opposite surfaces of the first light-transmitting member. It is disclosed that the first and second covers extend over edges of the opposite surfaces of the first light-transmitting member. In a second aspect of the present invention, a first cover disposed on a first parallel surface of a first light-transmitting member can be greater in thickness than a second cover. In some embodiments, it is disclosed that a second light-transmitting member with higher diffusion coefficient than the first light-transmitting member is disposed in contact with a first perpendicular surface of the first light-transmitting member.
