Entry Description

Lumen Touch is an interactive decorative luminaire that redefines the way users experience illumination. Rather than switching or dimming the light directly, users influence its behavior through subtle physical interaction: adding weight to the lower hook shifts the structure, expanding the space between two polished metal hemispheres, each containing an internal light source. Reflected uplight and downlight pass through iridescent filters, casting evolving color patterns onto the surrounding environment. Under daylight, the reflective surfaces scatter delicate hues, keeping the piece alive without artificial illumination. Acting as a reflective sculpture by day and an atmospheric luminaire by night, Lumen Touch invites users to explore light through touch and movement—transforming every interaction into a tangible, playful, and poetic experience that blurs the boundaries between product, art, and interaction.

Sustainability Approach

Lumen Touch embraces sustainability through structural efficiency, material integrity, and sensory economy. Its tensegrity system is entirely held by tensioned cords—without adhesives or rigid joints—allowing components to be detached, reused, and recycled, minimizing material waste and simplifying end-of-life separation. Though delicate and precise, the structure ensures long-term durability with minimal components and no wasteful assembly. Efficient LEDs and reflective optics create vivid illumination with very low energy, while iridescent surfaces remain active under daylight, offering a luminous experience without power. Through this balance of precision, restraint, and perceptual richness, Lumen Touch proves that sustainability can be both structural and emotional.
