Ellipsoidal — Ellipsoidal Reflector Spotlight (ERS), is a light used to highlight certain subjects or stage pieces with a relatively narrow beam angle.This light is best used for when you want to draw attention to a person by using multiple units. A Lekolite (often abbreviated to Leko) is a brand of ellipsoidal reflector spotlight (ERS) used in stage lighting which refers to the half-ellipsoidal dome reflector within which the instrument's lamp is housed. Par Light. Heat Filter. ‘The oil-bearing fluid inclusion morphologies include spherical, oval, ellipsoidal, lath-like and irregular shapes, although there is no obvious relationship between inclusion morphology and quartz cement history.’ ‘A primary concave parabolic mirror converges the light to one focus of a concave ellipsoidal … ... Ellipsoidal Reflector An ellipse is "a closed curve, generated by a point moving in such a way that the sum of its distances from two fixed points is constant." The line is a model of the ellipsoidal variations from a code written by former graduate student Jerry Orosz. ellipsoidal synonyms, ellipsoidal pronunciation, ellipsoidal translation, English dictionary definition of ellipsoidal. The light bounces off the reflector in all directions. Example: flat paint. A filter which transmits visible light and either absorbs or reflects infrared in order to reduce the amount of heat in a beam. Introduced in 1933, it was developed by Joseph Levy and Edward Kook, founders of Century Lighting, which eventually became a part of the Strand Lighting Corporation. The part of an ellipsoidal spotlight that contains the reflector, i.e., not the lens barrel or the cap. Depending on the manufacturer, ellipsoidals (lekos, spotlights) are known by their lens system (6x12, 6x9), or by their field angle in degrees (20 degree, 30 degree). An ellipsoid is a 3-dimensional ellipse. LED Lekos have all of the same benefits of a conventional lamped leko but add the ability to change color from the lighting controller. instrument having a gate at their focal point which enables the insertion of gobos or irises to shape the beam of light Template Slot A piece of metal or glass, which fits into the gate of a an ellipsoidal to project a pattern onto the set; Sometimes called a template or breakup. ... See the definition for Par Light. In electrodynamics, elliptical polarization is the polarization of electromagnetic radiation such that the tip of the electric field vector describes an ellipse in any fixed plane intersecting, and normal to, the direction of propagation. ellipsoid The equation for an ellipsoid is x2/a2 + y2/b2 + z2/c2 = 1. LED Ellipsoidals (lekos) are part of the continuing evolution of Stage Lighting. What do those numbers mean? Imagine being able to use a wash of lighting with shutter-ability and gobo project-ability made out of ellipsoidals but having an almost unlimited color choice. An ellipsoidal reflector has two focal points; light … The light, or more accurately the lens found in the lighting fixture, is named after the French engineer Augustin-Jean Fresnel who invented the technology for lighthouses in the early 1800s. His invention was so well received at the time that he was nominated to be the commissioner of lighthouses in France. Ever get stressed over which light to hang where? ERS stage lights always have adjustable focus and can have gobos placed in them to project patterns or logos. The different curves are different filters; B and V are blue and green light, and I, J, and K are different bandpasses of infrared light. Define ellipsoidal.
