    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 first light emitting element, a second light emitting element, a third light emitting element, a fluorescent material, a film, a first lens, a second lens, and a third lens. The first light emitting element is to emit a first light having a peak wavelength in a range from 440 nm to 485 nm. The second light emitting element is to emit a second light having a peak wavelength in a range from 495 nm to 573 nm. The third light emitting element is configured to emit from a third front surface a third light having a peak wavelength in a range from 440 nm to 485 nm. The fluorescent material is provided on the third front surface and has a fluorescent side surface extending along a front-rear direction. The film is provided to surround the side surface and the fluorescent side surface.

    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.

    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.
