For what purpose would I choose to use an ellipsoidal light on stage?
Ellipsoidal An ellipsoidal reflector spotlight produces an intense, well-defined beam of light that is perfect for front lighting. You can adjust the focus with soft or sharp edges, use shutters to adjust the shape of the lighting and keep the light from bleeding into areas you want to remain dark.9 Jun 2021
What is the biggest advantage of an ellipsoidal reflector spotlight?
The biggest advantage of the ERS is its lower power consumption; the cost savings in electricity offset the higher initial cost of the instrument.
What type of lenses does an ellipsoidal spotlight use?
The ellipsoidal reflector spotlight combines an ellipsoidal reflector usually with either one step lens or two plano-convex lenses “belly-to-belly”.
What is unique about an ellipsoidal reflector?
Ellipsoidal Reflectors These reflectors have two conjugate foci. Light from one focus passes through the other, after reflection. Ellipsoids collect a much higher fraction of total emitted light than a spherical mirror or conventional lens system.
What are ellipsoidal reflector spotlight used for?
Ellipsoidal reflector spot (abbreviated to ERS, or colloquially ellipsoidal or ellipse) is the name for a type of stage lighting instrument, named for the ellipsoidal reflector used to collect and direct the light through a barrel that contains a lens or lens train.
What feature is unique to an ellipsoidal reflector spotlight?
EFFICIENT SPOTLIGHT An ellipsoidal reflector spotlight features a built-in reflector in the shape of half an ellipse. By positioning the source light within the ellipse, rays of light emanating from the source are bounced off the surface and reflected to a single point, called the conjugate focal point (CFP).30 Jan 2013
What is a ellipsoidal in Theatre?
Definition of ellipsoidal spotlight : a spotlight used in theatrical lighting that contains an ellipsoidal reflector and that is particularly designed for long throws and is more efficient than conventional spotlights, reflecting rays that others waste.
What is an ellipsoidal light used for?
Ellipsoidals can be used for any job but their primary function is to illuminate a specific proximity. They are the common use for spotlights as they can give a small sharp circle. It has an ellipsoidal reflector behind the lamp to reflect the light in the direction required.
What is the difference between a Fresnel lantern and a PAR can?
The Fresnel has a sharp quality, even light that is often used as a direct source. Much like an open faced light, the PAR is so powerful it is usually diffused or bounced unless it is used to simulate the sun or other extremely powerful source and has less of a defined shadow pattern.4 Mar 2014
What is an ellipsoidal stage light?
Ellipsoidal reflector spot (abbreviated to ERS, or colloquially ellipsoidal or ellipse) is the name for a type of stage lighting instrument, named for the ellipsoidal reflector used to collect and direct the light through a barrel that contains a lens or lens train. ERS instruments come in all shapes and sizes.
How does an ellipsoidal light work?
An ellipsoidal reflector spotlight features a built-in reflector in the shape of half an ellipse. By positioning the source light within the ellipse, rays of light emanating from the source are bounced off the surface and reflected to a single point, called the conjugate focal point (CFP).30 Jan 2013
