Light-emitting device, lighting device, display device, and method for manufacturing light-emitting device

摘要

A light-emitting device includes a light-emitting element, a phosphor layer containing a phosphor that is excited by the light emitted by the light-emitting element to emit fluorescence, a substrate with the light-emitting element and the phosphor layer on the surface, and a resin body that seals the light-emitting element and the phosphor layer. An additional member is provided on an opposite surface opposed to the light-emitting surface of the light-emitting element on the surface of the resin body. The additional member at least reflects or diffuses the light emitted by the light-emitting element and the phosphor layer.

主权项

1. A light-emitting device comprising:
at least one light source, a substrate provided with the light source on the surface, a resin body that seals the light source, and an additional member that at least reflects or diffuses the light emitted by the light source, wherein the resin body is hemispherical and has a top view diameter of 4.5 mm or less, in a cross section including a normal line that is perpendicular to the surface of the substrate and passes through the light source, there exists a part where the top view length of the light source is 10% or more of the top view length of the resin body, and a top surface of the resin body is a concave depressed surface having an inclined surface of an inverted cone, and a space enclosed by the concave depressed surface is filled with the additional member.
