摘要:
A light-emitting device includes a substrate mounted with a light-emitting element, and a frame disposed on the substrate. The frame includes a first frame portion disposed on the substrate and surrounding the light-emitting element, and having an inner wall surface substantially perpendicular to an upper surface of the substrate, an upper end of the inner wall surface being positioned at a level higher than that of an upper surface of the light-emitting element, and a second frame portion surrounding the inner wall surface of the first frame portion when viewed in a plan view, and having an inner periphery which is so shaped as to extend at an outward incline from a lower end of the inner periphery to an upper thereof. The light-emitting device includes a wavelength converter supported on the frame and opposed to the substrate with a gap.

To improve the luminance of light emitted by a light-emitting device, the light-emitting device includes a base (1) that has an opening part (1p) constituted by a light-reflecting surface (1r) and a bottom surface (1u), a light-emitting chip (2) that is mounted on the bottom surface (1u) of the opening part (1p), a transparent member (3) that covers the light-emitting chip (2), and an optical member (4) that is disposed on the transparent member (3). The transparent member (3) is disposed on the bottom surface (1u) of the opening part (1p) in a state where the transparent member (3) is spaced away from the light-reflecting surface (1r) of the opening part (1p).

A light-emitting apparatus provides a ceramic-made base body, a frame body, a light-emitting element, a conductor layer and a light-transmitting member. The base body has on its upper surface a mounting portion for the light-emitting element. The frame body is joined to the upper surface of the base body so as to surround the mounting portion, with its inner peripheral surface shaped into a reflection surface. The wiring conductor has its one end formed on the upper surface of the base body and electrically connected to the light-emitting element, and has another end led to a side or lower surface of the base body. The light-transmitting member is disposed inside the frame body so as to cover the light-emitting element, which contains fluorescent materials for performing wavelength conversion. The base body is so designed that ceramic crystal grains range in average particle diameter from 1 to 5 μm.

A light emitting device includes a light emitting element, a base, and a transparent layer. The base has an upper side portion including a first portion and a second portion. The first portion includes a mounting region of the light emitting element, and has a first porosity. The second portion surrounds the first portion, includes a plurality of transparent particles, and has a second porosity larger than the first porosity. The light transmitting layer encapsulates the light emitting element, and is attached to the first portion in a state where the transparent layer is apart from the second portion.
