Ellipsoidal Reflector Spotlight (ERS) with Cookie Insert
An ellipsoidal spotlight, also known as Leko or Source Four, is a type of spotlight commonly used in theatrical lighting. It is characterized by its ellipsoidal reflector and lens system that produces a sharp and adjustable beam of light. The shape of the reflector helps to focus the light and control the beam's shape and size.
The cookie insert, also known as a gobo, is a thin metal or glass pattern that is inserted into the spotlight to create different light patterns and shadows. When the cookie is inserted into the ellipsoidal spotlight, it projects the pattern of the cookie as a cast shadow onto the stage or backdrop.
This combination of the ellipsoidal spotlight with a cookie insert allows lighting designers to create intricate and customizable lighting effects for stage productions, concerts, events, and other theatrical performances. By using different cookies or gobos, a wide range of designs, shapes, and textures can be projected, adding depth and visual interest to the lighting design.
In conclusion, an ellipsoidal spotlight with a cookie insert is a versatile lighting tool that adds a creative element to lighting design, allowing for dynamic and visually stunning effects on stage.
