  • Patent number: 8746932
    Abstract: In the production of a light emitting device, in which a plurality of light emitting element parts carrying LED elements are formed on a substrate, and the substrate is diced, generation of shaving dusts is suppressed at the time of the dicing, and breakage of the substrate during the production process can be prevented. In the process of forming a slit crossing a region for forming a light emitting element part in a metal substrate, a recess which serves as a resin reservoir can be formed so as to cross the slit. The slit can be filled with an insulating material, the recess can be filled with a resin, and they both can be cured. A light emitting element part can be formed in the region for forming the light emitting element part, the metal substrate can be cut into units comprising one or a plurality of the light emitting element parts, and can be mounted on a printed circuit board on which a pattern is formed.

  • Patent number: 8508118
    Abstract: A light-emitting device that suppresses color unevenness can be provided. A transparent member can be disposed on a fluorescence-containing resin layer. Part of excitation light can be emitted upward from an edge surface of the fluorescence-containing resin layer directly and without passing through the transparent member. Thus, fluorescent light emitted in large quantities from a place near an edge surface of the transparent member can be mixed with the excitation light emitted from the edge surface of the fluorescence-containing resin layer directly without passing through the transparent member, thereby suppressing color unevenness at a location near the edge surface of the transparent member.
