100-mm Light Ceiling – Edge Illumination: Efficient Lighting for Striking Ceiling Designs
A ceiling can make rooms brighter. But it can do more than that: it can create ambiance, highlight brands, and transform a flat surface into a true design element. The LED light ceiling with a 100-mm profile and edge lighting is perfect for exactly that.
It combines a sturdy aluminum profile with efficient LED technology and customizable fabric banners. The result is a large-scale lighting solution that truly shines when used with colorful, textured, or vibrant designs. For the industrial, advertising, retail design, and architectural sectors, this creates a flexible solution that is technically sophisticated, cost-effective, and visually striking.
Edge illumination: Light coming from the sides
In edge-lit designs, the LED modules are mounted on the sides of the frame. In the PRIMEX light ceiling with a 100 mm profile , the LED modules are mounted opposite each other on the long sides. This allows the light to be projected into the surface in a space-saving manner, creating a softly glowing visual effect. The standard color temperature is approximately 6,500 Kelvin, ensuring a neutral, high-contrast display. The luminous flux is approximately 4,680 lumens per meter along the long side.
This technique is particularly interesting when the light ceiling is not intended merely as a plain white functional surface, but rather as a visually striking ceiling solution. Colorful imagery, nature motifs, graphic patterns, or dynamic brand motifs take on a special depth thanks to the edge lighting.
Made for colorful designs
Not every illuminated surface needs to appear technically uniform. In many projects, the focus is on the design element itself: a sky above a waiting area, a graphic brand identity in a showroom, an atmospheric ceiling design in a retail space, or a creative lighting installation in an office.
Edge lighting is particularly advantageous for images with intense colors, textures, or non-uniform patterns. Slight variations in brightness generally do not interfere with such images; in fact, they can even enhance the visual effect. For technically uniform white surfaces or very specific medical cleanroom requirements, however, area lighting is usually the better choice.
That is exactly why the 100-mm light ceiling is an excellent solution for rooms that are meant to be not only bright but also designed to evoke emotion.
100 mm Profile: Sturdy, Efficient, and Project-Friendly
The 100-mm aluminum profile is designed for efficient edge-lit illumination. The LED modules are mounted along the side profiles, creating a lighting solution that is both compact and powerful. The design is suitable for widths up to approximately 3.0 meters and lengths up to 20 meters.
This is particularly valuable for large-scale ceiling solutions. In long hallways, retail spaces, lobbies, showrooms, or reception areas, illuminated ceilings can make a significant impact on the space while also being cost-effective to install.
For architects, this means greater design freedom. For retail designers, it offers a flexible solution for retail spaces and brand environments. For signage specialists, the system provides a solid foundation for changing graphics and eye-catching spatial designs. In industrial settings, it is suitable for visitor areas, presentation rooms, or training areas.
Large formats require sturdy structures
A light ceiling must not only look good, but also remain taut and clean-looking over the long term. Especially with larger sizes, dimensional stability, secure installation, and a uniform appearance are crucial. That is why the 100-mm-profile light ceiling features additional stabilizing frames integrated approximately every 220 cm. These increase the stability of the aluminum frame and help ensure that the light surface remains taut and clean-looking over the long term.
In practice, this is a decisive advantage. When a ceiling surface is large, nothing should look improvised. The fabric should hang smoothly, the frame should remain stable, and the lighting effect should look professional. It is precisely this technical reliability that makes this solution particularly appealing for commercial and public interiors.
Textile Printing with Diffusion and Blockout
The effect of a light ceiling depends heavily on the fabric. For its 100 mm light ceiling, PRIMEX uses custom, photorealistic textile printing. The special fabric features an integrated diffusion layer to ensure that the light is distributed as evenly as possible. A white blockout backing prevents light from escaping from the back. Printing is done using the sublimation process with water-based inks. In addition, the fabric meets the B1 classification according to DIN 4102 and the B-s1, d0 classification according to EN 13501, making it suitable for public indoor areas.
This is important for professional projects. In retail spaces, medical offices, offices, showrooms, or public areas, it’s not just about a beautiful design—it’s also about safety, durability, and a high-quality overall look.
Changing the design without tools
Spaces change. Campaigns come and go, brand identities are adapted, and interior design concepts continue to evolve. The 100-mm-profile light ceiling is designed to accommodate these changes: The printed fabric is secured using a piping system and can be replaced without tools.
This makes the solution particularly cost-effective. Instead of replacing the entire system, only the graphic is updated. For store designers, signage specialists, and industrial companies, this is a major advantage when ceiling surfaces need to be used long-term while remaining visually flexible.
Controls, Colors, and Installation
Depending on the project, the light ceiling can be dimmed—either via remote control or an app. This allows the lighting ambiance to be adjusted based on the time of day, usage, or brand presentation. The profile is available as standard in silver anodized or matte black. Matte white, white with a fine texture, and other RAL colors and surface textures are available upon request.
The installation process is also designed with practicality in mind. The light ceiling is delivered disassembled to reduce shipping volume and costs. As a result, the modular frame construction fits even in smaller vehicles or elevators. Ceiling mounting brackets are included in the scope of delivery; screws and anchors are selected on-site to suit the substrate.
Where the 100-mm Light Ceiling Shines
Typical applications include offices and reception areas, medical practices and healthcare facilities, retail and sales spaces, as well as promotional and event areas. In these settings, the light ceiling can be used as an accent light surface, a soothing ceiling feature, a space for seasonal campaigns, or a portable lighting display.
For industrial companies, it can enhance visitor areas and brand spaces with a high-end look. For signage specialists, it creates a powerful canvas for visual communication. For retail designers, it brings emotion and draws attention to sales areas. For architects, it opens up new possibilities for designing lighting and ceilings as a unified whole.
Conclusion: Edge lighting for atmospheric ceiling surfaces
The 100-mm illuminated ceiling with edge lighting is an efficient solution for large-scale light displays featuring striking designs. It combines sturdy aluminum construction, side LED lighting, interchangeable fabric prints, and flexible design options.
It is particularly appealing to the industrial, signage, retail design, and architectural sectors when the goal is to make spaces not only brighter, but also more vibrant, striking, and emotionally engaging.
After all, good lighting doesn't just come from above. It creates a lasting atmosphere in the room.
