Introduction to the Two-Tier Artam Tree Project
Designing urban lighting elements requires a precise balance between structural strength and visual aesthetics. The “Two-Tier Artam Tree” project in Qom, standing at an impressive height of 8.6 meters, is a prime example of this synergy.
This element is designed and executed with two distinct canopies. The lower canopy, with a diameter of 6.5 meters, and the upper canopy, spanning 4.5 meters, create an expansive lighting coverage. This design acts as a modern architectural structure during the day and adds a brilliant, aesthetic glow to the urban landscape at night.

Metal Framework and Structural Stability
In constructing elements of this scale and height, chassis durability and public safety are the top priorities. The Artam luminous tree structure is specifically engineered to remain completely stable against atmospheric pressures and seasonal winds.
Metal Structure and Component Quality
The entire body of this luminous tree weighs approximately 1,600 kilograms, reflecting the use of heavy-duty, robust materials. The structure consists of two separate sections with multiple branches, all fabricated from standard-thickness industrial profiles. This smart engineering choice ensures that while the structure remains elegant and visually appealing, it offers exceptionally high resistance to environmental stress and vibrations.
Substructure and Foundation
To secure and support such immense weight and height, a specialized, engineered substructure is executed at the installation site. The foundation of this project is designed with precise excavation and heavy rebar reinforcement. The use of thick 10mm base plates means the bottom section of the structure alone weighs 400 kg. This guarantees that the Artam tree remains firmly anchored in place, even during the harshest storms and adverse weather conditions.

Lighting System and Component Safety
In outdoor projects, illumination is only half the story; equipment durability and public safety are far more critical. The lighting of the Two-Tier Artam Tree is executed with a combination of forty-five 10-meter LED string lights and 4cm pixel lights, creating a breathtaking volume of light across the two separate canopies. The entire system operates on a safe 24V power supply, effectively reducing the risk of electric shock in public spaces to zero. Additionally, to maximize circuit durability against power fluctuations, sun-resistant double-sheathed wiring and independent fuses for each pathway are utilized, ensuring consistent and reliable illumination every night.
Beyond electrical safety, all components are fully fortified against harsh climates and intense solar radiation. By utilizing Zener LEDs equipped with Epistar chips—protected by a specialized, transparent, UV-resistant industrial resin coating—moisture and dust penetration into the system is rendered impossible. This advanced technology prevents the LEDs from clouding or losing brightness over the long term. Furthermore, the integration of custom PLT mounting frames securely locks all lighting equipment in place, providing absolute stability against severe winds and potential physical impacts.
