  • Publication number: 20230207752
    Abstract: A light-emitting device 100 includes: a light-emitting element; a light-transmissive member covering the light-emitting element; and a light-diffusing agent contained in the light-transmissive member and comprising hollow particles. The light-transmissive member has a first surface having irregularities according to the light-diffusing agent. The first surface of the light-transmissive member has a convex shape with a height gradually increased from a peripheral portion of the first surface toward a central portion of the first surface.

  • Publication number: 20220254966
    Abstract: A light emitting device including a fluorescent material with reduced hue, and a method of manufacturing the light emitting device are provided. A light emitting device 100 includes: a light emitting element 1; a first light-transmissive member 3 covering the light emitting element 1; and a light diffusing member 5 contained in the first light-transmissive member 3. The light diffusing member 5 includes hollow particles. The surface of the first light-transmissive member 3 has irregular shapes attributed to the light diffusing member 5. The first light-transmissive member 3 is covered with a second light-transmissive member 4. The second light-transmissive member 4 has a convex structure in which the center is the uppermost point. The irregular shapes attributed to the light diffusing member 5 are covered with the second light-transmissive member 4.

  • Patent number: 11355678
    Abstract: A light-emitting device includes: at least one light-emitting element; a first light-transmissive member covering the light-emitting element; a second light-transmissive member covering the first light-transmissive member; and a light-diffusing member in the second light-transmissive member. The light-diffusing member includes hollow particles. The second light-transmissive member has a bottom surface having irregularities due to presence of the light-diffusing member.

  • Patent number: 10454007
    Abstract: A light-emitting device includes: a light-emitting element; a light-transmissive member that covers the light-emitting element; and a light-diffusing particles contained in the light-transmissive member. The light-diffusing particles are hollow and have a particle size not smaller than 50 ?m. The light-transmissive member has a surface having irregularities associated with the light-diffusing particles. A method for manufacturing a light-emitting device includes steps of: mounting a light-emitting element in a recess of a base member; injecting a silicone resin containing light-diffusing particles into the recess, the light-diffusing particles having a particle size not smaller than 50 ?m; causing the light-diffusing particles to float up to a surface of the injected silicone resin; and curing the injected silicone resin.
