What is a Leko (ellipsoidal reflector spotlight)?
A Leko, short for ellipsoidal reflector spotlight, is a type of lighting fixture commonly used in theatrical and dance productions. It is known for its ability to produce a strong, focused beam of light that can be easily controlled and shaped. The Leko is a versatile tool that can be used to highlight performers, create dramatic effects, and set the mood of a production.
How does a Leko work?
The Leko works by using a combination of lenses, reflectors, and a lamp to create a powerful and controllable beam of light. The lamp, typically a high-intensity discharge or incandescent bulb, produces light that is then focused by the reflector and passed through a series of lenses to shape and direct the beam. The ellipsoidal shape of the reflector helps to create a sharp, well-defined beam that can be easily focused and adjusted.
What are the different parts of a Leko?
A Leko consists of several key components, including the lamp, reflector, lenses, shutters, and gobo holder. The lamp is the light source that produces the initial beam of light, while the reflector helps to focus and shape the light. The lenses are used to further shape and control the beam, while the shutters allow for precise control over the size and shape of the light output. The gobo holder is a slot where a gobo, a metal or glass pattern, can be inserted to create custom shapes or textures in the light beam.
How is a Leko used in dance productions?
In dance productions, Lekos are commonly used to highlight performers, create mood lighting, and add visual interest to the stage. They can be used to illuminate specific areas of the stage, such as the dancers or set pieces, while keeping the rest of the stage in darkness. Lekos can also be used to create dynamic lighting effects, such as patterns, textures, and color changes, to enhance the overall visual impact of the performance.
What are the benefits of using a Leko in dance productions?
There are several benefits to using Lekos in dance productions. One of the main advantages is their ability to produce a strong, focused beam of light that can be easily controlled and shaped. This allows for precise lighting effects and the ability to highlight specific areas of the stage. Lekos are also energy-efficient and produce less heat than traditional incandescent fixtures, making them a more sustainable option for lighting designers. Additionally, Lekos are versatile tools that can be used in a variety of ways to enhance the visual impact of a dance performance.
How to properly set up and focus a Leko for a dance performance?
Properly setting up and focusing a Leko for a dance performance is essential to achieving the desired lighting effects. Here are some steps to follow:
1. Position the Leko: Place the Leko in the desired location on the stage, ensuring that it is securely mounted and angled correctly.
2. Insert the lamp: Install the appropriate lamp in the fixture, making sure it is securely seated and aligned properly.
3. Focus the beam: Use the focus knob on the Leko to adjust the position of the lenses and create a sharp, well-defined beam of light.
4. Shape the beam: Use the shutters on the Leko to control the size and shape of the light output, ensuring that it is directed where it is needed.
5. Add a gobo: If desired, insert a gobo into the gobo holder to create custom patterns or textures in the light beam.
6. Test the lighting: Once the Leko is set up and focused, test the lighting to ensure that it is achieving the desired effects and making any necessary adjustments.
By following these steps and properly setting up and focusing the Leko, lighting designers can create stunning lighting effects that enhance the overall visual impact of a dance performance.
