Abstract:
1. A glass-coated light-emitting element comprising: a semiconductor light-emitting element having a surface and a plurality of electrodes formed on the surface; and a spherical glass having a sphere shape with a cut portion and covering the semiconductor light-emitting element such that the surface of the semiconductor light-emitting element forms a surface portion of the cut portion of the sphere shape, wherein the sphere shape of the spherical glass has a spherical surface broader than a hemispherical surface, the spherical glass has a refractive index of 1.7 or more at an emission peak wavelength of the semiconductor light-emitting element, and a ratio of a diameter of the spherical surface to a maximum diameter of the surface of the semiconductor light-emitting element on which the electrodes are formed is 1.8 to 3.5.
