Illuminated lettering not only improves a sign's visibility at night, but also provides a distinctive, modern, and professional touch. It's a key resource for highlighting brands, signposting spaces, and creating visual impact in all types of projects, both indoors and outdoors.
There are two main ways to illuminate your corporate letters: direct or indirect. Choosing the right type of lighting will depend on the visual objective, the location of the sign, and the available budget.
Types of lighting: direct light vs. indirect light
1. Direct light (front or internal)
In this type of lettering, the illumination shines directly onto the front of the letter. This is achieved through the use of opal or translucent acrylic on the front, combined with an LED light source inside. It's ideal for achieving high visibility and a modern effect, especially outdoors.
2. Indirect light (backlit or halo effect)
Here, the light is projected from the back of the letter onto the surface where it's installed, creating a halo effect around the outline. The light source is hidden inside the letter, creating an elegant and more subtle effect. To create this effect, the sign must be installed at a certain distance from the wall so that it can reflect off the wall and create the effect.
Many clients ask us if it's possible to install it over vertical gardens and if it maintains the effect. The truth is that because the wall is so uneven, the light isn't reflected evenly, and the desired result isn't achieved. To solve this problem, you could use a colored base (white, black, etc.) under the letters so that the light bounces off the base instead of directly onto the vertical garden.
Methods and materials for illuminating corporate letters
1. Letters with opal methacrylate and interior LED lighting
Opal methacrylate (also called translucent white acrylic) is used as the letter face when direct light is desired. It allows LED light to pass through evenly, creating a clean and elegant glow. It is highly weather-resistant and retains its color over time.
Most modern lettering uses internal LED lighting systems, either for direct or indirect lighting. LEDs offer low energy consumption, long lifespan, and high light intensity, as well as the ability to change colors or add dynamic effects.
2. Openwork letters with light bulbs (vintage or marquee style )
In some decorative designs, especially for interiors or events, openwork letters with visible light bulbs are used. This retro style offers a striking aesthetic and is ideal for shop windows, trade shows, or spaces with a creative and casual approach.
3. Letters with perimeter or combined lighting
Some designs combine direct and indirect light or include edge lighting (side lighting), creating unique three-dimensional effects. This is an ideal option for projects with a high visual impact.
You can combine different colors, both from the LEDs and from the face of the letter itself. You can also modify the thickness of the lighting, creating deeper or shallower letters depending on the size and your needs.
Frequently Asked Questions
Can illuminated letters be installed outdoors?
Yes. All lighting systems can be adapted for outdoor use, as long as waterproof materials and appropriate IP protection are used.
What maintenance do they require?
Very low. Just wipe the front with a damp cloth and make sure it's still lit as usual!
Can the color of the light be changed?
Yes. With RGB LED technology, dynamic and programmable color effects can be created.
Conclusion
Lighting completely transforms the appearance of corporate letters. Whether with direct or indirect light, or with bulbs... light adds character, visibility, and style. Choosing the right system is key to reinforcing your brand image and standing out in any environment.
