    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 base has a base surface. Light emitting elements are disposed on the base surface along an X-axis with an X pitch and along the Y axis with a Y pitch to form a matrix. The X pitch is smaller than the Y pitch. Lenses has a batwing illumination distribution. Each of the lenses covers each of the light emitting elements. A first lenticular lens sheet is provided on the base such that a first lenticular lens sheet lower surface is opposite to the base surface. A second lenticular lens sheet is provided on the first lenticular lens sheet such that a second lenticular lens sheet lower surface is opposite to a first lenticular lens sheet upper surface. A third lenticular lens sheet is provided on the second lenticular lens sheet such that a third lenticular lens sheet lower surface is opposite to a second lenticular lens sheet upper surface.

    Abstract: A package includes a first electrode and a second electrode that are located at a bottom portion of a bottomed recess, and a first resin securing the first electrode and the second electrode in place and forming a part of the bottomed recess. The first electrode has a first outer lead having a first indentation at a tip in a plan view. The second electrode has a second outer lead having a second indentation at a tip in a plan view. The first resin has at least a portion between the first electrode and the second electrode located at the bottom portion of the bottomed recess, wall portions structuring lateral walls of the bottomed recess, and flange portions having the same thickness as a thickness of the first outer lead and different outward widths from the wall portions on both sides of the first outer lead in a plan view.

    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.
