Ellipsoidal light is gaining popularity day by day. The alternative to ellipsoidal light is a spotlight. It has vast applications. The major function of this light is to produce different types of beams and shapes. They are very accurate. The intensity of light is controlled with the help of a lens, reflector, or lens system. This makes it a very good tool for producing different kinds of light effects at the same time. Another important thing is that they are fixed in one place. However, there are many manufacturers of stage lighting products. In this post, you learn about the historical background of ellipsoidal light, what an ellipsoidal light is, the types and consistencies of ellipsoidal light, types and consist of ellipsoidal light etc.

Historical Background of Ellipsoidal Light
Louis Hartmann invented the practical lensed spot light in 1879. The first electric spotlight installed in America on stage was at Boston Bijou’s theatre in 1882. Hartmann created a baby lens in 1904 that was 50 times brighter than a candle.
In 1933, the ellipsoidal spotlight (also known as Leko light) was invented. It focuses light on a small, very focused area of a theatre. The ERS is a mainstay of theatre lighting. The light is usually round, but the shape can be altered using a gobo, an iris, or a shutter (a metal template that is placed inside a light fixture in order to project an image onto a surface). Components include the bulb, blades to shape the light and lens.
What is an Ellipsoidal Light?
There are three names for ellipsoidal light. One is an LED ellipsoidal light, the second is an ellipsoidal profile spot, and the third is an ellipsoidal spotlight. The ellipsoidal spotlight uses a reflector that collects and directs the light into a barrel containing a lens. The focus can be changed by adjusting the tube. This is done by pulling or pushing the tube further into the unit. Ellipsoidal light fixtures are commonly used in theaters, nightclubs, lighting design, and film / television production.
Ellipsoidal reflectors have a strong, defined light and are versatile. The field angle of ellipsoids can range from five to 90 degrees. The field angle is the angle at which the light beam reaches 10% of its intensity in the middle of the beam. This is mainly used at large theatres, TV stations, and press conferences. The LED theater spotlight is a high-quality lighting system that can be used in studios, theatres, and other areas that need high-quality lighting.

Who are the many types of LED ellipsoidal light?
Based on the degree, there are two different types of LED ellipsoids: fixed LEDs and variable zoom.
(1) Fixed-degree LED Ellipsoidal Light
LED ellipsoidal lenses are available in 19 degrees, 26 degrees, 36 degrees, and 50 degrees.
How do I choose different lens degrees for ellipsoidal LEDs? One thing you need to keep in mind is that if the distance is short, choose a large degree. If it is long, choose a small degree. If the distance between stage and target is 10 meters, then you should choose elliptical LED lights with a 50-degree or 36-degree angle. You need to use a small-angle or 19-degree ellipsoidal light if the distance is between 20 and 30 meters.
(2) Ellipsoidal light with Variable Zoom
For ellipsoidal lighting fixtures, the most common variable zoom lenses are 12° to 30° and 25° to 50°.
What consists of an ellipsoidal light?
Three main components make up an ellipsoidal lamp: the light source (lamp), which is located in the rear or engine; the shutters that are in the barrel and shape the light; and the lens at the front.

1: Ellipsoidal reflector
The ellipsoidal-shaped reflector is what shapes the beam of light. The ERS is a shallow elliptical plate that has been coated with aluminum or another highly reflective material. The light is focused on a small area when the light source is placed at the center of the ellipse. The size and shape can be altered by adjusting the lamp’s position within the reflector.
The adjustable shutters of an ellipsoidal lamp are barn doors or blades that can be placed around the lens in order to shape the light beam. The shutters are used to create sharp edges, feather the light, or block light from certain areas on the stage.
3: Lens tube
A ERS includes an additional lens tube, which can be changed to change the beam’s focus or spread. These lens tubes, which are also called “barn doors,” contain a number of lenses that can either be zoomed in or out to focus the beam or spread out to a wider flood.
Benefits of ellipsoidal lighting
The ability to adjust ellipsoidal lighting for different effects is one of their main advantages. With interchangeable lenses and shutters, the beam can be focused and shaped, while the angle of light can be changed using a mirror system. Lighting designers can create many different looks and moods using ellipsoidal lighting.
The high quality of the light produced by ellipsoidal lights is also well known. The beam of light is usually very bright, with a smooth and even intensity. This makes it perfect for lighting up people and objects on a stage. The ellipsoidal light is designed to be both energy-efficient and long-lasting, which makes it a cost-effective lighting option for events and stage production.
How do I use ellipsoidal light?
Classics remain classics because they are timeless. They are known for their quality performance and will remain until something new is introduced. Ellipsoidal fixtures have been around for a long time. Stage lighting needs them to frame the stage.
You can create a soft or sharp circle of light by using an iris and framing shutters. Ellipsoidal fixtures can be used to project Gobos on logos or scenery. There are smaller Gobo projects that serve this purpose better.
In essence, ellipsoidal lighting is needed to focus on and illuminate specific parts of a set.
Wattage is used to gauge the brightness of a fixture. Often, lumens are not provided as a measurement. The fixture in the video above, for example, is 200 watts. This is an incredibly bright LED ellipsoidal.
LED ellipsoidal lights often have color LED engines. With a simple RGB+W engine, you can create thousands of vibrant colors while creating a pleasing light. Some fixtures only produce a warm white but can be colored with color gels.
Smaller is a good way to think about lens sizes. A smaller circle will be equal to a smaller degree. You have two choices with most ellipsoidal fixtures: a zoomable optic or the option to change lens tubes.
Where Are Ellipsoidal Lights Useful?
The ellipsoidal spotlights will look great anywhere where there are live performances. Ellipsoidals are suitable for all lighting jobs, but they’re best used to light up a particular area in your performance space. These light fixtures will make a noticeable difference on your stage. You might not have noticed something missing in your performance, but you will notice it once they are installed.
Some of the places where ellipsoidal lighting can be used include:
Stages during live sets by performers
Theatres and music venues for stage performances and concerts
Spaces for dances, other events and functions
Houses of Worship, Churches
Reflector spotlights will energize and engage your crowds in ways you never imagined possible.
Why use ellipsoidal lights?
Anyone who has seen a live show knows how spotlights can create dramatic emphasis just at the right time. There are several ways that ellipsoidal lighting can enhance performance.
By directing the audience to a particular point or performer.
This can be done by creating the impression that there is nothing beyond the performers or objects in the spotlight. It can be used to convey the importance of what a character says.
An ellipsoidal lighting fixture can add the most value to a production by enhancing the experience of the audience. It’s worth investing in if the audience is more engaged.

Ellipsoidal spotlights are high-quality lenses with a high CRI and a consistent color. This ensures high-definition photography. The lenses have two conjugate focal points, so that light from the first focus is reflected through the second.
However, they capture a higher percentage of the total light emitted than a conventional lens or spherical-mirror system. Lighting designers and technicians can use shutters to soften the edges of beams or cut certain parts. Usually, they are used to create color washes. You can use them with either a glass or metal gobo.
Frequently Asked Questions
Q1: What is the purpose of ellipsoidal lighting?
Ans: They can be used in any situation, but their main purpose is to light up a particular area. The most common application for spotlights is to create a small, sharp circle. The lamp has an ellipsoidal-shaped reflector to direct the light.
Q2: What is the principle of an ellipsoidal mirror?
Ans: In general, an ellipsoid has two focal points and the light that passes through one focal point also passes through the other focal point after being reflected by the elliptical surface. By Using this principle, if one light source is placed on one focal point, it is possible to collect light at the other focal point.
Q3: What is the shape and size of an ellipsoidal mirror?
Ans: An ellipsoidal spotlight with a reflector built in features a reflector that is shaped like a half-ellipse. The light source is placed within the ellipse. Rays of light are bounced from the surface and then reflected at a single focal point called the conjugate focus point (CFP).
Q4: How does an ellipsoidal reflector work?
Ans: ERSes have four shutters that are used to frame the beam of lighting. When the projected image is inverted, pressing the left shutter will remove the right side, and pushing the top shutter will remove the bottom.
Q5: What is an ellipsoidal theatre?
Ans: The ellipsoidal reflector of a spotlight for theatrical lighting is designed to provide long throws. This spotlight is more efficient because it reflects the rays wasted by other spotlights.
