The lighting tools used in events, concerts, and stage shows perform the important role of creating magical moments which immerse the audience.
One of these tools is the gobo, which allows the lighting designer to be more creative. A gobo is most likely the reason a shape, pattern, or logo is projected onto a floor, wall, or backdrop.
En este artículo hablaremos de la definición de gobos en iluminación, su funcionamiento, clasificación y los criterios para elegir los mejores gobos para escenarios. Además, explicaremos cómo utilizarlos para diseñar eventos de forma que la sorpresa se perciba en cada detalle.
¿Qué es un gobo en iluminación?
A gobo is a template or stencil that is put into a luz gobo para proyectar un haz de luz con un diseño predeterminado. La palabra "gobo" proviene de la frase inglesa "goes before optics" (va antes de la óptica), es decir, desde la fuente de luz hasta la lente que ilumina el diseño.
En lugar de emitir un haz simple, la luz atraviesa los patrones recortados del gobo, proyectando ese diseño sobre la superficie.
Gobos may be as simple as in the case of circles and stars, or they may be as detailed as in the case of company logos or scenic patterns.
Some other common uses of the gobos may include:
- Creating and adding stage textures in the background.
- Projecting the highlighted initials of the couple on the dance floor as a mic cutout.
- Projecting company logos on them during corporate events.
- Creating natural-look effects in theater which include leaves, rippling water, or clouds.
Una de las mejores características de los gobos es la capacidad de hacer que la iluminación resulte interesante al instante sin necesidad de tecnología sofisticada.
How Do Gobos Work in Lighting?
The process of gobo is simple and the outcome can be extraordinary. El proceso consta de los siguientes pasos:
- Colocar el gobo en una ranura específica dentro del dispositivo.
- Activating the light, which allows it to shine through the gobo shape.
- The projection lens focuses the beam, projecting the shape onto a wall, stage floor, curtain, or even onto the ceiling.
-
La proyección se puede modificar en cuanto a nitidez, tamaño preestablecido o rotación.
Gobos are intended for spot, moving head, and profile lights. Used with color filters, the effects possible are even more stunning.
Por ejemplo, al proyectar una luz verde sobre un gobo con un patrón de hojas, el escenario puede transformarse para parecer que está situado en un bosque.
Why Are Gobos Important for Stage Shows?
Cada espectáculo escénico busca crear y mantener una atmósfera que cautive al público. Los gobos contribuyen a la iluminación del escenario mediante:
1. Crear ambiente: A combination of patterns and colors can create emotions. For instance, during a romantic wedding, heart-shaped gobos may be utilized to evoke the appropriate atmosphere while a rock concert may have edgy, sharp designs.
2. Branding: Business marketers cherish gobos as they can project their logos and slogans on any surface, thus demonstrating advertisement through illumination.
3. Storytelling: Gobos can project scenes such as a window frame or forest canopy in a theater to match the act. This is very useful in set-less, Minimalist rehearsals.
4. Energía y emoción: Concerts are now enhanced with live rotating gobos that create jet-like streams of light, and with the addition of moving headlights, they become even more electrifying.
Lighting design would be lacking a significant portion of creativity and personality without gobos.
Different Types of Gobos
Gobos are not all alike. The imprint, materials, and process all dictate the figure that gets projected on stage. The choice of gobo type can affect the shot, color and durability of the design and so it is recommended to select wisely.
Let’s examine the three most common categories of gobos used today in iluminación escénica.
Glass Gobos: For Stunning, High Detail Projections
Professional events utilize glass gobos as they are the most durable. Such gobos are made of heat-resistant borosilicate glass which can endure the overheated stage lighting fixtures. The image may be etched or printed onto the glass, ensuring sharp and intricate details.
Why glass gobos stand out:
- Detalle ultra nítido: Ideal for intricate patterns, fine text, and complex artwork.
- Full color projection: Bright display of multi colored designs for logos or themed events.
-
Calidad profesional: Conciertos, producciones teatrales y eventos corporativos de branding muestran logotipos e imágenes con gran detalle.
Consider, for instance, a corporate conference: a glass gobo projects a multi colored company logo onto a stage backdrop for the sharpest and most vibrant result.
¿Desventaja? El aspecto profesional que aportan hace que los gobos de vidrio merezcan la pena frente a los de acero o plástico.
Steel Gobos: Economical and Tough
El tipo de gobo más resistente es el de acero. Se fabrica con finas láminas de acero inoxidable cortadas con láser. Los gobos de acero soportan mucho calor sin deformarse, lo que los hace muy duraderos.
Why steel gobos are a good choice:
- Can withstand wear and tear: Steel gobos can be used for many years without suffering any damage.
- Affordable: Great for those on a budget.
- Can be used for bold shapes: simple stars, arrows, and hearts can be used.
However, steel gobos cannot produce very fine details. The reason for this is that the steel cutouts have to be joined by thin metal bridges. If you need complex designs or text, you are better off with glass.
You are most likely to spot steel gobos at a live concert, nightclub, or outdoor festival, which is where the price and durability are more useful than the details.
Plastic Gobos: Lightweight and Perfect for Use with LED Lighting Fixture
Fabricados con lámina resistente al calor o acrílico, los gobos de plástico son ideales para luces LED más frías, ya que pueden derretirse con el calor que generan las luces halógenas. Se pueden imprimir en colores vivos y son económicos y ligeros.
Ventajas de usar gobos de plástico:
- Reduced price: Uso temporal o con presupuesto reducido.
- Impresión a todo color: Allows for intricate graphics and colorful artwork to be displayed.
-
Lightweight: Simple to move and manage.
They are common for social functions like weddings, birthday parties, and community gatherings, where the colorful and fun effects are needed on a budget.
Pro Tips:
- For professional, long-term repeated use, glass is the best choice.
- If the need is for something long-lasting yet low in cost, go for mild steel.
- For a colorful projection on an LED light that won’t be in use for a long time, plastic works best.

Gobos have the ability to enhance stage lighting in captivating and dynamic ways. The kind of gobo effect you select will influence the atmosphere of your event.

Ejemplos:
- Swirling galaxy effect for a musical performance.
- Rotating snowflakes for a winter-themed stage performance.
- Formas geométricas en movimiento para un ambiente moderno y enérgico.
Gobos animados: Añadiendo movimiento a una escena
Animation of gobos is done by layering them or using mechanical movement for them to operate. Animated gobos are ideal for theater design or for staged setups that are meant to be immersive.
Ejemplos:
- Flickering flames for dramatic scenes.
- Flowing water ripples for ocean backdrops.
-
Clouds are moving across the moonlit sky.
