Abstract
A light emitting device includes a light emitting element and a lens, The lens includes a cover part and a light-shielding part. The cover part includes a lens part, a connection part, and a flange part which are formed of a thermosetting first resin and continuous to one another. The light-shielding part covers an outer lateral side of the connection part and is formed of a second resin having a greater light-absorptance or a greater light-reflectance than the first resin. The lens part is disposed at a location that allows light from the light emitting element to be transmitted through the lens part.
Claims5
A light emitting device comprising:
- a light emitting element;
- and a lens, wherein
- the lens includes:
- a cover part including a lens part, a connection part connected to an outer periphery of the lens part, and a flange part connected to a lower-end portion of an outer periphery of the connection part;
- the lens part and the connection part defining a recess opening downward, the lens part defining a bottom surface of the recess and the connection part defining lateral surfaces of the recess and surrounding the opening of the recess;
- the flange part extending outward from a periphery of the recess, and
- the lens part, the flange part, and the connection part being formed of a thermosetting first resin and continuous to one another;
- and
- a light-shielding part covering an outer lateral side of the connection part and formed of a thermosetting second resin having a greater light-absorptance or a greater light-reflectance than the first resin;
- and
- wherein the lens part is disposed at a location that allows light from the light emitting element to be transmitted through the lens part.
