Lightmurface

Lightmurface is a term describing surfaces whose optical response is engineered to shape light at the boundary between air and matter. The concept encompasses designs that combine micro- and nano-scale topography with responsive or high-contrast materials to influence how light is reflected, transmitted, or scattered. Lightmurface behavior is often realized with metasurfaces, photonic-crystal–like coatings, or engineered diffusers, sometimes integrated with coatings or active elements to adjust performance under different lighting conditions.

Principles of lightmurface include resonant scattering, phase discontinuities, and controlled diffusion. Through precise geometry and material choice, a lightmurface can produce effects such as directional reflection, angle-dependent color, or selective transmission without relying on pigments. Dynamic variants employ electro-optic, liquid-crystal, phase-change, or stretchable elements to alter the optical response in real time, enabling adaptive control over brightness, contrast, or visibility.

Applications for lightmurface concepts span architectural daylighting and façades, automotive and consumer electronics coatings, wearable displays, and art installations. In architecture, lightmurface coatings can modulate glare and brightness while preserving color neutrality under varying illumination. In product design, they offer pigment-free coloration, enhanced contrast, or tunable transparency, contributing to energy efficiency and aesthetics.

History and terminology: Lightmurface is not a standard term in core physics but appears in design and research literature as a descriptive label for surfaces that actively manage light at the boundary. It overlaps with metasurfaces and photonic crystals, yet is used to emphasize practical surface engineering and application-oriented outcomes.
