The object looks quite simple: a tubular envelope sealed at the ends by a stainless steel shell. But in reality, this concept is a concentrate of technology and know-how. Today, we offer a range of lighting solutions for architectural applications.
Mechanical resistance #
A tubular body enhances the mechanical strength of its materials by distributing mechanical stresses more evenly, creating a high degree of rigidity. The absence of longitudinal joints also ensures material homogeneity and increases impact resistance. As a result, our luminaires boast exceptional shock resistance (IK10 – 20 joules), guaranteeing long-lasting durability.
Waterproofing #
Our tubular luminaires are hermetically sealed (IP68), ensuring maximum luminous flux over time, thanks to the absence of internal dust.
Minimum length #
The greater the joint length, the greater the risk of infiltration: on our tubular devices, the seal is made at the end of the pipe, keeping the joint length to a minimum.
Even clamping #
The seal’s force of application must be uniform and constant over time across the entire bearing surface: by design, the central stainless steel screw closure applies a uniform force at every point on the seal’s bearing surface. The specific shape of the gasket reservoir – a hollow half-ring – also creates a triple sealing barrier.
Constant maintenance #
“The elastic deformation of the stainless steel mask absorbs the expansion and mechanical stresses exerted on the luminaire body throughout its life. The materials used for our gaskets (sulfur-free EPDM, silicone, etc.) have been selected for their high resistance over time.
Easy to clean #
The tubular shape of our luminaires minimizes the deposit of external dirt, making them easy to clean. Their hermeticity prevents internal dust deposits, guaranteeing optical performance and limiting maintenance operations. If necessary, in heavily used public spaces such as railway stations, their construction allows high-pressure jet cleaning (IP69 K).
The wiring #
The heat generated by the components and external temperature variations cause the insulation to age. Our luminaires feature silicone-insulated internal wiring braided with fiberglass. Silicone, resistant to temperatures of up to 180°C, guarantees the lifetime of the insulation, while fiberglass ensures that the mechanical integrity of the wiring is maintained.
Fasteners #
Practice #
All our luminaires are fitted with quick-release clamps for easy mounting and dismounting. As an option, we offer a range of technical clamp solutions covering a wide variety of uses: torx tamper screw-secured version to secure luminaires, hinged version for maintenance by tilting the luminaire.
Techniques #
Tubes are sensitive to radial mechanical stress and shear (risk of cracking over time). For this reason, the geometry of the elements, the thickness of the various straps and the positioning of the welding locations have been optimized to eliminate any risk of damage to the bowl. The elastic deformation of the clamps absorbs dimensional variations caused by thermal and mechanical shocks to the luminaire body throughout its life.
The materials #
Lighting in public buildings requires luminaires that meet the specific requirements of the public: impact, intensive use, ageing… 50 years “experience in the design and use of industrial luminaires has led us to select the most suitable materials to guarantee exceptional longevity of our products” technical and aesthetic features.
Stainless steel #
All our external metal parts (plates, clamps, screws, etc.) are made of 304 L stainless steel. This low-carbon, austenitic chromium-nickel stainless steel offers excellent corrosion resistance and toughness. It requires minimal maintenance and retains its appearance over time. It should only be used in chlorinated environments (pool surrounds).
Basins #
The polycarbonate selected for our tubular basins is the material offering the best compromise between IK10 mechanical strength (20 joules), fire resistance (960°C incandescent) and optical qualities for our interior architectural applications. Whether in high-transparency versions for directional products or satin-finish versions for products with diffuse optics, their aesthetics and mechanical properties stand the test of time.
