Why is lighting crucial at an event?
Creating an immersive atmosphere
Light has the power to transform the atmosphere of a place. A warm hue can evoke friendliness, while a cool light suggests modernity. By modulating the intensity, color, and direction of the light, various atmospheres can be created: romantic, festive, solemn, or dynamic. For example, during a gala dinner, dim lighting in golden tones creates an elegant and warm ambiance. In contrast, for an electro night, colorful beams and strobe effects energize the dance floor.
Guiding the audience
Beyond aesthetics, lighting plays an essential functional role. It ensures the safety of movement, especially in dark or crowded areas. Light markings, clear signage, and supplementary lighting help prevent accidents and facilitate public orientation.
The different types of spotlights and their uses
PAR Spotlights
PAR (Parabolic Aluminized Reflector) spotlights are classics in stage lighting. Their wide and homogeneous beam is ideal for ambient lighting or color washes over large surfaces. Available in halogen or LED versions, they offer a varied color palette thanks to the use of filters or RGB LEDs.
Versatility and dynamism
Moving heads, or lyres, are motorized spotlights capable of moving on two axes (pan and tilt) and adjusting their parameters in real-time. There are mainly three types:
- Spot Lyre: produces a sharp beam, ideal for projecting gobos (patterns) or precise effects.
- Wash Lyre: offers a wide and diffuse beam, perfect for coloring a stage or set.
- Beam Lyre: generates a very narrow and powerful beam, creating spectacular effects, especially with the addition of smoke or fog.
Precision and movement
Scanners use a movable mirror to direct the light beam, providing fast and precise movements. They are often used for dynamic effects synchronized with music. Follow spots, on the other hand, are manual spotlights that allow tracking a moving artist on stage. Their intense and focused beam highlights the main subject while leaving the rest of the scene in shadow.
Strobes, lasers, and special effects
To add excitement to an event, nothing beats luminous special effects such as strobe lights that emit rapid flashes, creating the illusion of jerky movement; lasers that project very fine beams of light, often used for impressive visual shows; and smoke or fog machines that make light beams visible in the air, enhancing the light effects.
Modern lighting technologies
The advent of LED
LEDs have revolutionized event lighting. More energy-efficient, more durable, and more compact than traditional sources, they offer great flexibility. With RGB (Red, Green, Blue) or RGBW (adding White) technology, it is possible to create an infinite number of colors without using filters.
Moreover, LEDs generate little heat, reducing the risk of burns and the need for air conditioning. They also allow for smoother dimming effects and better responsiveness.
The magic of programming
The DMX (Digital Multiplex) protocol is the standard for controlling lighting. It allows for the control of up to 512 channels (or more with extensions), each corresponding to a specific parameter: intensity, color, position, etc. DMX consoles, whether physical or software and hardware offer an interface to program scenes, sequences, and effects. Thanks to them, the lighting designer can synchronize the lights with the music, create smooth transitions, and adapt the lighting in real time.
For perfectly coordinated shows, synchronizing the lights with the music is essential. Timecode, a temporal signal, allows for precise alignment of light changes with the highlights of a soundtrack. This technique is particularly used in concerts, dance performances, or multimedia shows, where each element must be perfectly timed for a professional result.
Light scenography: between art and technique
The role of the lighting designer and the lighting technician
The lighting designer is the artist behind the light displays. They do not simply turn on projectors; they tell a story, create an atmosphere, and emphasize an emotion. Their role is to transform a neutral space into a true living stage. To achieve this, they work closely with directors, set designers, technical managers, and sometimes even the artists themselves. As for the lighting technician, they ensure that all the technical aspects are in place: installation, safety, coordination, management of the lighting desk or DMX console… They make sure that what has been envisioned becomes reality, without a hitch. Together, these two roles are essential to the success of any lighting project, especially in large-scale events.
The importance of the lighting plan and the technical sheet
It is impossible to talk about lighting without mentioning the lighting plan. This is a precise diagram representing the placement of all the lights on stage or in a venue. Each light source is positioned according to its role: wash, front, back, side, etc. This document is a true bible for technicians, as it conditions all technical implementation.
The technical sheet, on the other hand, lists all material and electrical needs: types of lights (moving heads, PARs, LEDs, follow spots), number of circuits, necessary power supply, cabling, consoles, etc. It is often attached to an artist's or a show's rider and helps ensure a performance that meets artistic and technical expectations.
Total immersion
Video mapping is a spectacular discipline where light becomes image. Using high-power projectors, a building facade, a stage structure, or an object is transformed into an animated projection surface. Combined with well-thought-out lighting scenography, mapping enhances the audience's immersion, creating striking visual metamorphoses. This technique requires meticulous preparation: 3D surveys, projector alignment, synchronization with light, and sometimes even sound. Here, lighting plays a complementary role, allowing for alternation between projection and light to enhance storytelling or energize transitions.
Essential accessories
Structures, bridges, and projector stands
Before making the light shine, it must first be installed. This is where structures come into play: aluminum bridges, suspended grids, motorized poles, telescopic stands... These elements are used to position the projectors at the desired height and angle while ensuring their stability. The quality of the attachment is crucial. Suitable hooks, safety slings, and a weight verification... nothing should be left to chance. A poor fixation can lead to a serious accident. That is why the lighting technician must always adhere to load standards and check each anchoring point.
Customizing the light
To modify the color or texture of a beam of light, simple but effective accessories are used:
- Filters and gels: colored films placed in front of the lens, allowing the light to be tinted according to a color chart (CMYK, RGB, warm white, cool white...).
- Gobos: metal or glass disks, pierced with patterns, that are inserted into certain projectors to project shapes, logos, or textures.
The nerve of the war is electricity. Each projector must be powered correctly, without overload or short circuit. For this, power strips, extension cords, dimmers, DMX cables, and sometimes distribution boxes are used.
Architectural and decorative lighting
Highlighting buildings and outdoor spaces.
During an outdoor event (inauguration, concert, festival, wedding), architectural lighting reveals the beauty of a site. Facades, trees, paths, or monuments are illuminated using powerful projectors, often equipped with filters or directional focuses. Specific colors can also be used to evoke a cause (pink for Pink October, blue for a global day) or simply to add flair to an ordinary structure. By playing with backlighting, light showers, or halo effects, the lighting becomes visual poetry.
Creating a unique atmosphere
Light is the soul of a decor. It transforms a simple marquee into a magical circus stage, a raw warehouse into a refined gala hall. By manipulating transitions, sequences, and colors, one can completely change the identity of a place in just a few seconds. Light design is the art of composing with light as one would with painting or music. The goal: to evoke an emotion, guide the gaze, and create an unforgettable experience for the viewer.
Safety and regulations
When it comes to events, safety is a priority. Lighting is no exception. One must consider the marking of exits, luminous signage, and the installation of emergency lighting units (BAES) that activate in case of a power outage. Each installation must comply with strict standards: independent circuits for emergency lighting, autonomy of safety blocks, readability of light panels… All of this is governed by regulatory texts that technicians must master.
Standards and Best Practices
Beyond legal obligations, certain best practices ensure the safety of property and people:
- Check the condition of the equipment before each use.
- Never overload an electrical circuit.
- Use appropriate mounting accessories.
- Train teams in handling consoles and DMX controllers.
Conclusion
Event lighting is not just about illuminating a stage or a room. It is a true light staging, capable of transforming an ordinary place into a magical, vibrant, and immersive space. Behind every beam, every effect, every nuance, there is an artistic and technical intention, a desire to touch the audience and enhance the moment. Thanks to the evolution of technologies such as LED, DMX, mapping, and synchronization systems, the possibilities are now endless. Whether you are an event organizer, technician, or simply passionate, understanding and mastering the challenges of lighting ensures an unforgettable visual experience.
