Abstract

A light-emitting device includes a mounting board, a first light-emitting element, a second light-emitting element and a light-reflective covering member. The mounting board includes first lands and second lands on an upper surface of the mounting board. The first light-emitting element is flip-chip mounted on the first lands. The second light-emitting element is flip-chip mounted on the second lands. The light-reflective covering member covers a lateral surface of the first light-emitting element, a lateral surface of the second light-emitting element, and the upper surface of the mounting board. The mounting board and the light-reflective covering member define a depressed portion between the first light-emitting element and the second light-emitting element with a bottom surface of the depressed portion being located inside the mounting board.

Dependent claims

A light-emitting device comprising:

a mounting board including first lands and second lands on an upper surface of the mounting board, one of the first lands being spaced apart from one of the second lands adjacent to the one of the first lands on the upper surface of the mounting board;
a first light-emitting element flip-chip mounted on the first lands;
a second light-emitting element flip-chip mounted on the second lands;
and
a light-reflective covering member covering a lateral surface of the first light-emitting element, a lateral surface of the second light-emitting element, and the upper surface of the mounting board, wherein
the mounting board and the light-reflective covering member define a depressed portion between the first light-emitting element and the second light-emitting element with a bottom surface of the depressed portion being located inside the mounting board, and
in a top view, an outer edge of a part of the depressed portion defined by the mounting board coincides an outer edge of a part of the depressed portion defined by the light-reflective covering member.
