Abstract
A light emitting structure includes a substrate, a light emitting unit disposed on the substrate, an annular wall, a first bonding layer adhering to the annular wall and the substrate, and a compound body. The light emitting unit is arranged inside of the annular wall. The annular wall, the first bonding layer, and the first surface surroundingly define a gap. The compound body is arranged in a space defined by the annular wall, and includes a reinforcing portion filled in the gap so as to connect the annular wall, the first bonding layer, and the substrate.
Claims18
A light emitting structure, comprising:
- a substrate;
- a light emitting unit disposed on the substrate;
- and
- an annular wall, a first bonding layer, and a compound body, wherein the annular wall is fixed on the substrate through the first bonding layer and the compound body, and the compound body includes a reinforcing portion filled in a gap defined by the annular wall, the first bonding layer, and the substrate.
A manufacturing method of a light emitting structure, comprising:
- implementing a preparing step by disposing a light emitting unit on a substrate and fixing an annular wall to the substrate through a first bonding layer, wherein the annular wall is arranged around the light emitting unit, and the annular wall, the first bonding layer, and the substrate surroundingly define a gap;
- implementing a filling step by filling a liquid compound in a space surroundingly defined by the annular wall, and then vacuuming a surrounding environment to gradually form a vacuum environment so as to fill the liquid compound into the gap;
- and
- implementing a solidifying step by solidifying the liquid compound to form a compound body, wherein a portion of the compound body filled in the gap is defined as a reinforcing portion, and the reinforcing portion connects the annular wall, the first bonding layer, and the substrate.
