Abstract: A method of manufacturing a lens includes: injecting a thermosetting first resin in a first mold, and curing the thermosetting first resin, to form a cover blank having cover parts; removing a part or all parts of the first mold; arranging the cover blank in a second mold; injecting a thermosetting second resin having a greater light absorptance or a greater light reflectance than the thermosetting first resin into the second mold and curing the thermosetting second resin, to form a lens blank having a light-shielding part between adjacent ones of the cover parts; taking out the lens blank from the second mold; cutting the lens blank at the light-shielding part located between the adjacent ones of the cover parts to obtain individual lenses having lateral side walls and flange parts extending outward from lower-end portions of the lateral side walls, which are both covered by the light-shielding part.

Abstract: A 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.

Abstract: A lens includes a cover part and an interposing member formed of a light-reflecting material. The cover part includes a lens part having a lateral side, a connection part constituting a lateral side wall extending from the lateral side, and a flange part having a lower surface disposed below the lateral side wall. The interposing member has an upper surface and an inner lateral surface. The upper surface is disposed on the lower surface of the flange part. The lens part and the interposing member define a recess having an opening facing downward. The lens part defines a bottom surface of the recess. The inner lateral surface defines a lateral surface of the recess, which defines the opening of the recess. The flange part extends outward from the opening. The lens part has a convex lens and a light-emitting surface with projections outward from the convex lens.

Abstract: A lens includes a cover part and a light-shielding part. The cover part includes a lens part, a connection part, and a plurality of flange parts, formed with a thermosetting first resin and continuous to one another. The light-shielding part covers lateral end surfaces and an upper surface of each of the flange parts and outer lateral sides of the connection part and formed with a thermosetting second resin having a greater light-absorptance or a greater light-reflectance than the thermosetting first resin.

Abstract: A lens includes a cover part and a light-shielding part. The cover part includes a lens part, a connection part extending downward from lateral sides of the lens part, and one or more flange parts each extending outward from a lower-end portion of the connection part. The lens part and the connection part define a recess having an opening facing downward. The flange parts extend outward from a periphery of the opening of the recess. The lens part, the flange parts, and the connection part are formed of a thermosetting first resin and continuous to one another. The light-shielding part covers outer lateral surface of the connection part and is formed of a thermosetting second resin having a greater light-absorptance or a greater light-reflectance than the thermosetting first resin. The flange parts have a greater thickness than the connection part.

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.

Abstract: A method of manufacturing a lens including forming a cover blank having cover parts by injecting a thermosetting first resin in a first mold and curing the thermosetting first resin, removing a part or all parts of the first mold, and arranging the cover blank in a second mold. The method further includes forming a lens blank having a light-shielding part between adjacent cover parts by injecting a thermosetting second resin having a greater light absorptance or light reflectance than the thermosetting first resin into the second mold and curing the thermosetting second resin, and obtaining individual lenses by taking out the lens blank from the second mold, and cutting the lens blank at the light-shielding part located between adjacent cover parts to obtain individual lenses each with lateral end surfaces and an upper surface of each of flange parts and lateral side walls covered by the light-shielding part.
