摘要： A light-emitting device includes a light-emitting element 110; and a lens section 132 covering over the light-emitting element 110. The lens section 132 includes an entrance surface S1 on which light from the light-emitting element 110 is incident; an exit surface S2 from which the light incident on the entrance surface S1 is emitted; and an optical axis L extending so as to penetrate the entrance surface S1 and the exit surface S2. A concave section 132a is formed in an area of the exit surface S2, which contains the optical axis L, and two flat sections 132b are formed so as to face each other across the optical axis L. The exit surface S2 defines an upwardly-protruding curved surface formed between the two flat sections 132b, and the optical axis L is coincidence with a reference optical axis of the light-emitting element 110.

摘要： A light quantity distribution control element includes a substrate of 20 mm×20 mm×3 mm made of a material that transmits light, such as optical glass or acryl, and a antireflective structure provided on a surface of the substrate. As the antireflective structure, a conical antireflective structure of a pitch of 0.15 μm (periodic structure having conical convexities) is formed. This corresponds to a antireflective structure having a pitch of a wavelength or less in the ultraviolet band (150 nm to 400 nm) at the time when ultraviolet light is used as incident light.
