An optical sheet 43 is built into a liquid crystal display apparatus in which a plurality of light sources 42 are dispersed on a back surface side of a display screen. One surface of the optical sheet 43 has an uneven surface. In a predetermined region R on the one surface of the optical sheet 43, a luminance enhancer 25 that improves the total light transmittance of the predetermined region R is provided so as to at least partially fill recesses 22a of the uneven surface.

A light-up beverage container or drinking vessel has a double wall construction made up of an inner container and an outer container, the inner container having a frustoconical, straight-walled shape and the outer container having a curved sidewall when viewed from the side. In order to achieve an attractive illuminated appearance, the curved outer sidewall of the preferred drinking vessel includes facets or prism structures formed in and extending around a circumference of the curved sidewall.

A runway-embedded flash lighting device includes, a body configured for embedding in a runway, a ceiling member with a flash emission window, a bottom cover member, a light guide member disposed in the flash emission window, and two or more flash emission windows. The light guide member is disposed in each of the flash emission windows and an inner surface of the ceiling member is provided with a site to be disposed with a LED flash light source below the flash emission window. The LED flash light source includes, an LED module, a frame-shaped attaching plate; and a lens member. The lens member is attached to a hollow portion in a frame of the frame-shaped attaching plate, and is configured to allow an emission surface of the flash emitted from the LED module to have a uniform illuminance distribution.

Optical elements and systems are disclosed that can be incorporated into buildings to prevent beam sunlight from entering through apertures of the building while allowing diffuse skylight to enter the building through the apertures. The optical system comprises optical elements configured to admit diffuse skylight through an aperture in the building envelope, while reflecting away the beam sunlight incident on the aperture in the building envelope. The apertures can be, for example, windows in walls or skylights in roofs of the building envelope. The optical system works for both windows in the walls and skylights in the roof, with somewhat different configurations for those two parts of the building envelope.
