Klieg lights. A Klieg light is an intense carbon arc lamp especially used in filmmaking.It is named after inventor John Kliegl and his brother Anton Kliegl.Klieg lights usually have a Fresnel lens with a spherical reflector or an ellipsoidal reflector with a lens train containing two plano-convex lenses or a single step lens.
LED film, also called LED-embedded light film [1] is a new technology of surface-mount light-emitting diodes (LEDs) on flexible transparent conductive polymer films. This technology is based on the use of a cold curing pick-and-place process on transparent conductive plastics.
Daylight redirecting film (DRF) is a thin, flexible plastic film which can be applied to a window to refract or reflect incoming light upwards so that the deeper parts of the room are lit more evenly. It can be used as a substitute for opaque blinds. [2] It is a form of prism lighting.
Fresnel lenses can be placed close to the light source and are inexpensive to produce. In film lighting lenses range in size from 2 to 24 inches, and lamp power between 150 W and 24,000 W. Fresnels use a spherical reflector, with the filament of the lamp at its focus point. This effectively doubles the light delivered by the fixture, as all ...
Thin-film phosphor electroluminescence was first commercialized during the 1980s by Sharp Corporation in Japan, Finlux (Oy Lohja Ab) in Finland, and Planar Systems in the US. In these devices, bright, long-life light emission is achieved in thin-film yellow-emitting manganese-doped zinc sulfide material. Displays using this technology were ...
