Stefan Diez（ステファン・ディーツ）
インダストリアルデザイナー。ミッドガードの受賞歴を持つAYNO照明シリーズをデザイン。
Stefan Diez is one of Germany's leading industrial designers, internationally recognised for products that combine engineering precision, material intelligence and long-term sustainability. As the designer of the AYNO lighting family, Stefan Diez translated Midgard's pioneering engineering heritage into a contemporary lighting system. AYNO marked Midgard's first completely new lighting family in more than fifty years and introduces a fundamentally different approach to adjustable light.
ステファン・ディーツについて
ミュンヘンを拠点とするStefan Diez（ステファン・ディーツ）は、シュトゥットガルト州立造形芸術アカデミーを卒業後、Richard SapperとKonstantin Grcicのスタジオで経験を積み、2003年にDIEZ OFFICEを設立しました。
現在、ステファン・ディーツとそのスタジオは、HAY、Magis、Moroso、Thonet、Vibia、e15など、国際的に評価されるメーカーのために家具、照明、工業製品を開発しています。
ステファン・ディーツは、デザインを探究と洗練のプロセスとして捉えています。素材、部品、製造方法を検証し、明快で耐久性のある解決策へと導きます。エンジニアリング、サステナビリティ、美しさを別々の領域ではなく、同じデザインプロセスの中で結びつく要素として扱います。
その結果生まれるのは、精密で直感的であり、時を経ても価値を保つためのデザインです。
AYNO照明シリーズ
Designed by Stefan Diez for Midgard, AYNO represents a new chapter in the company's history while remaining closely connected to its origins. The lighting family includes table, floor, and wall luminaires. Every version is based on the same principle of controlled flexibility.
The movable adjustment rings alter the tension and curvature of the fiberglass rod, allowing the light to be positioned without conventional mechanical joints. The interaction is immediate and intuitive, while the construction remains visually and technically clear. AYNO continues Midgard's history by asking the same question in a different way: how can light be directed as precisely and simply as possible?
AYNOとサーキュラーデザイン・ガイドライン
Many of the principles that Stefan Diez later published as his Circular Design Guidelines emerged during the development of AYNO together with Midgard.
Longevity, repairability, material efficiency, responsible manufacturing and reduced complexity were integral to the development process from the beginning. Components were designed to be separated and replaced wherever possible. The construction was reduced without limiting functionality, and materials were selected not only for their technical properties but also for their role throughout the product's life cycle. Rather than treating sustainability as an additional feature, AYNO demonstrates how circular thinking can become an integral part of industrial design and product development.
Today, the Circular Design Guidelines are recognised internationally as a framework for responsible product development. AYNO remains one of the earliest industrial projects in which many of these principles were explored through close collaboration between designer and manufacturer.
デザインとエンジニアリングによるサステナビリティ
For Stefan Diez and Midgard, sustainability was an integral part of the design process itself. Reduced to the essentials, AYNO meets all criteria of design, technology, and sustainability: It is one of the first LED lights that can be repaired by the customer without tools.
Thanks to plug-in connections, all parts can be exchanged, not just the LED and transformer. It is made from already recycled materials; each part is reparable by hand, and the lamp is easily separated into the three fully recyclable primary materials. The use of semi-finished products avoids transport routes, standardized materials can be sourced locally.
The result is a lighting family conceived not for short product cycles, but for decades of everyday use.
