While traditional lighting is still struggling to balance brightness and energy consumption, we have leveraged the revolutionary optical technology of metasurfaces to create a smart lamp that can "understand the language of light." It breaks away from the limitations of traditional lamps that rely on a single optical structure, integrating non-local metasurface technology, jointly developed by Shandong Normal University and the Australian National University, into the lamp's design. This gives each beam of light the "intelligence" to be precisely controlled, bringing a disruptive revolution to the lighting field.
The core advantage of this metasurface smart lamp stems from its unique coupled resonator waveguide array design. The ultra-thin metasurface structure inside the lamp achieves a photon flat-band effect through deliberately disrupted symmetry in the weakly coupled waveguide—meaning that the light maintains uniform and stable brightness and color temperature regardless of the viewing angle in the room, completely eliminating the pain points of traditional lamps: "glaring when viewed directly, dim when viewed from the side." Even more astonishing is that the metasurface structure reduces the speed of light to near the zero group velocity, significantly enhancing the interaction between light and matter. This allows the light to be focused with razor-sharp precision, projecting clear text and patterns directly. Whether for focused desktop lighting in an office setting or ambient lighting projection in a home theater, this lamp handles it all with ease.
As the world's first lighting product to simultaneously achieve high Q-value flat-band effects and chiral effects, this metasurface smart lamp has reached unprecedented heights in light polarization control. It can accurately distinguish between left-handed and right-handed circularly polarized light, switching between unidirectional and bidirectional flat-band modes through an intelligent control system: In working mode, the light is focused in unidirectional flat-band mode, concentrating over 90% of the light on the work area, reducing ambient light interference and improving focus; in relaxation mode, the bidirectional flat-band mode allows the light to diffuse softly, creating a warm and soothing atmosphere when combined with adjustable chiral polarized light, even simulating the natural light and shadow changes of sunrise and sunset to alleviate visual fatigue.
The breakthroughs in metasurface technology are equally significant in terms of energy efficiency and durability. Traditional lighting fixtures often suffer from significant energy leakage due to their inefficient optical structures. This metasurface smart lamp, however, efficiently captures light through collective optical effects, increasing energy utilization by over 40% and consuming only 60% of the power of traditional LED lights at the same brightness. Simultaneously, the nanoscale manufacturing process of the metasurface structure gives it exceptional stability, resulting in a lamp lifespan of up to 50,000 hours, far exceeding the industry average, and eliminating the need for frequent light source replacements, significantly reducing maintenance costs.
From precise focusing in office lighting to creating ambiance in home life, from creative lighting design in commercial spaces to wide-angle uniform lighting in outdoor scenes, this metasurface smart lamp, with its advantages of "small size, multi-functionality, and high precision," adapts to all lighting needs. It is not just a lamp, but an innovative carrier that deeply integrates optical technology with everyday life—when the cutting-edge technology of metasurfaces meets daily lighting, light is no longer a simple "lighting tool," but a "spatial language" that can be controlled at will, opening up a more precise, dynamic, and energy-efficient world of light for you.
Now, this metasurface smart lamp, embodying cutting-edge optical wisdom, has officially debuted. It not only rewrote the technical standards of lighting products, but also redefined the way people interact with light. Choosing the Smart Light Blade means choosing to make every ray of light just right, turning lighting into an invisible boost to improving quality of life and work efficiency.
