[1] All light fixtures have a fixture body and one or more lamps.
George Izenour made the next breakthrough in 1969 with the first ever fixture to use a mirror on the end of an ellipsoidal to redirect the beam of light remotely. In 1969, Jules Fisher, from Casa Mañana area theatre in Texas saw the invention and use of 12 PAR 64 lanterns with 120 W, 12 V lamps fitted, 360 degrees of pan and 270 degrees of ...
A very complex dielectric mirror can reflect up to 99.999% of the light incident upon it, for a narrow range of wavelengths and angles. A simpler mirror may reflect 99.9% of the light, but may cover a broader range of wavelengths. Almost any dielectric material can act as a perfect mirror through total internal reflection. This effect only ...
PAR lamps and their fixtures are widely used in theatre, concerts and motion picture production when a substantial amount of flat lighting is required for a scene. They are often mounted in can-shaped fixtures known as PARCAN s, which can be used to generate colours by fitting them with colored sheets called gels .
Lighting designers typically use them with stage lighting instruments to manipulate the shape of the light cast over a space or object—for example, to produce a pattern of leaves on a stage floor. Gobos placed after the optics do not produce a finely focused image, and are more precisely called "flags" or "cucoloris" ("cookies").
