A parabolic aluminized reflector luminaire 20 PAR cans. A parabolic aluminized reflector lamp (PAR lamp or simply PAR) is a type of electric lamp that is widely used in commercial, residential, and transportation illumination. It produces a highly directional beam.
Parabolic Aluminized Reflector lights, or PAR lights, or PAR cans, are used when a substantial amount of flat lighting is required for a scene. A PAR can is a sealed beam PAR lamp housed in a simple can-like unit.
A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid , that is, the surface generated by a parabola revolving around its axis.
The followspot yoke is an oversized replacement yoke intended to allow an ellipsoidal reflector spot to be installed into a followspot stand and be used as a small, short throw followspot. Generally these yokes allow a much wider range of tilt than a conventional yoke, and have had the hole for a c-clamp bolt replaced with a spigot for a spot ...
It uses two reflectors. The primary reflector is a parabolic reflector and the secondary reflector is a spherical reflector. The parabolic reflector organizes the light into nearly parallel beams, and the spherical reflector is placed in front of the lamp to reflect light from the lamp back to the parabolic reflector, which reduces spill.
Scoop. In stage lighting, an ellipsoidal reflector floodlight (sometimes known by the acronym ERF which is often pronounced "erf"), better known as a scoop, is a large, simple lighting fixture with a dome-like reflector, large high-wattage lamp and no lens.
Metal substrates ("Metal Mirror Reflectors") may also be used in solar reflectors. NASA Glenn Research Center, for example, used a mirror comprising a reflective aluminum surface on a metallic honeycomb [1] as a prototype reflector unit for a proposed power system for the International Space Station. One technology uses aluminum composite ...
Reflectors may be made of polished metal, glass, or plastic with an aluminized reflective finish. Some manufacturers use a pebbled or "orange peel", instead of a smooth reflector, to improve the uniformity of the light beam emitted. Where multiple LEDs are used, each one may be put in its own parabolic reflector.
