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).
What is a Fresnel light? The Fresnel (pronounced fre nel’) is one of the most flexible fixtures to work with, being designed to create a relatively even field of light with adjustable intensity and field size. The light is named for its Fresnel lens, which bends the diverging rays of light emitted by the bulb into a controlled beam of light.
Why is it called a Leko? Century Lighting founders and the instrument’s inventors, Joseph Levy and Edward Kook, combined the first two letters of their own last names and called the unit “Leko.” Rival lighting company, Kliegl Brothers, released their own Elipsoidial Reflector Spotlight that same year, calling it “Klieglight”.
