Discarded Aluminum Blinds Reborn as Modular Lighting
Keker Collection transforms old blinds into innovative light objects through sustainable design.
1Design Born from Waste Material
Iranian designer Reza Raeisifar initiated the Keker project in 2018 after encountering discarded aluminum blinds in a storage space. Leveraging their light-control properties, he transformed them into lighting elements. The concept matured when invited to design lighting for Shiraz University's Afarinesh project. The design stands out for its material efficiency and functional transformation, showcasing innovative reuse of everyday objects.
2Modular Structure Details
Keker's first version features three laser-cut acrylic sheets forming the structural framework. Longitudinally cut aluminum slats are inserted into grooves, creating modular patterns. An energy-efficient LED at the center emits 360-degree lighting. The curved slats conceal the direct light source while creating dynamic shadow plays. This configuration maintains visual comfort while producing ever-changing light patterns.
3Technical Flexibility
The system adapts to various forms and lighting types. Its geometric arrangement ensures visual comfort while generating dynamic patterns. First exhibited in 2019 at Tehran's Ordibehesht Gallery, the complete collection debuted in 2025 at Design Gallery One. All versions maintain the same core construction principle. The design demonstrates how simple materials can achieve complex lighting effects through intelligent engineering.
4Versatile Application Options
The collection offers pendant, linear, ceiling, wall-mounted, and floor-standing versions. The Pendant edition creates sculptural effects with warm light, while the Wall Edition projects dynamic radial shadows. Each configuration maximizes visual impact with minimal material usage. Photographers Navid Atrvash and Arash Akhtaran documented the pieces, capturing their transformative qualities in different spatial contexts.
5Production Process Stages
Manufacturing begins with preparing recycled aluminum slats. Laser-cut acrylic sheets form the structural base. Gradual insertion of slats defines the lamp's form. The modular system allows multiple configurations. Final assembly secures the slats, revealing the completed design. This methodical process demonstrates how careful material handling can transform waste into high-design objects.
6Visual Dynamics
Repeated slat arrangements create both modular forms and visual rhythm. Development involved extensive testing of slat positioning and angles. By concealing and redirecting the light source, the design achieves impressive ambiance without glare. Under warm lighting, the pieces gain sculptural presence, adding character to spaces. The interplay of light and shadow changes with viewing angles.
7Sustainability Innovation
Keker proves waste materials can become high-quality design products. Transforming architectural elements demonstrates circular design potential. The collection minimizes environmental impact through material efficiency while delivering aesthetic value. It inspires sustainable practices in design communities worldwide. Such projects redefine value in material usage, challenging conventional production norms.
8New Industrial Design Approach
The collection models material reuse for industrial design. Raeisifar's approach encourages designers to see potential in everyday objects. Featured through Designboom's DIY submissions, it reached global audiences. Projects maximizing impact with limited resources illuminate future design practices. Keker represents how creativity can bridge sustainability and functionality in product design.
