![]() This gives the effect of divine intervention, or, if used with a green gel, alien abduction. They can also be used to god-spot actors by placing them at a sharp (5° - 10°) angle. Ellipsoidals are good for gobo projection, and highlighting actors or scenery on stage. ![]() ETC, who manufacture the Source 4, produce a variety of attachments, commonly called "barrels", to change the field angle of the Source 4.Įllipsoidals can be used for colour washes, with an attachment to change the field angle, but this job is better suited to PAR cans, Fresnels and Floodlights. Ellipsoidal reflector spotlightor 'Profile Spot' (abbreviated to ERS, or colloquially ellipsoidal, ellipse, Lekoor Shakespeare) is the name for a type of stage lighting instrument, named for the ellipsoidalreflectorused to collect and direct the lightthrough a barrelthat contains a lensor lens train. This prolongs the life of gels and gobos.Įllipsoidals can have either a fixed field angle, normally from 5° to 50°, or a variable field angle, commonly called a "Zoom". Dichroic reflectors only reflect light from the visible spectrum, allowing infrared ( heat) radiation to pass out the back of the light. Ellipsoidal Spotlight with 3-prong Edison plug combines the energy-saving power of the patented HPL lamp, with a dichroic reflector and optical-quality. ERS may also be referred to as Profile Spotlights (especially in Europe) because the beam can be shaped to the profile of an object. Light from one focus passes through the other, after reflection. The light source is provided that includes one or more white light emitting LEDs, the lights being arranged to direct a. Rubin continues, Commonly attributed seems due primarily to the fact that Lekolight (Levy and Kook) caught on as a kind of generic description, while Klieglight had a history more linked to bright arc sources and klieg-eyes. These spotlights are designed to highlight a specific performer in a powerful circle of light. A reflector spotlight luminaire includes a housing defining an optical axis. Some ERSes, notably the Source Four, also include a dichroic reflector, so the beam is much cooler than other lights. These reflectors have two conjugate foci. Ellipsoidal light, also known as ellipsoidal reflector spotlight (ERS), leko light, profile spotlights (in Europe), is a type of stage lighting fixture, named for the ellipsoidal reflector used to collect and direct the light through a barrel that contains a lens. It is a fact that the first ellipsoidal reflector spotlights were manufactured and introduced into the field by Kliegl Bros. Its Ellipsoidal lens means only a 500w or 750w bulb is needed, instead of a 1000w bulb, while retaining the same brightness. ![]() There are several advantages of the ERS that make it one of the most common lights in a theatre. ![]()
