The Field of Light – A drama of lights and shadows
1. Prologue of Light
Natural Fire and the Light of Civilisation
Since humans began to use fire approximately 1.8 million years ago, light has been central to the development of civilisation. In the UNDERSKY showroom, PMT Partners turns light’s primal role as a source of protection into the conceptual foundation of the space. The pairing of light and heat changed the material conditions of life and shaped our sense of safety and warmth.
In contemporary approaches to healthy living, light is understood as more than illumination. The showroom traces its development towards environments that respond to the body’s daily rhythms, linking today’s design to a much longer human search for light.




A hazy prologue
UNDERSKY develops lighting technologies for healthier living environments, including its Oxygen Care Light and Golden Light. PMT Partners gives these products a spatial narrative through a carefully planned route.
At the entrance, frosted glass blocks create a mysterious threshold. A moving halo behind them suggests the passage of time and draws visitors into the showroom, beginning their journey through light.


2. Theatre of Light
Scenes and changing roles
The showroom introduces the idea of a theatre. Domestic settings become a sequence of story-filled boxes that demonstrate light in daily life. Visitors can observe the effects of healthy lighting through framed openings or enter the rooms themselves and experience how changing light alters their perception.

Two routes through the space
Based on the research of optical engineering and behavioral psychology, we have constructed a dual experience path inside and outside. The outer circulation provides a sensory visual experience. The lights light up one by one with the “plot”, guiding visitors like watching a drama, initially stimulating curiosity and attention to healthy light. The inner circulation focuses on immersive experience. The audience walks into the scene and takes on the role of the performer, feeling the subtle psychological touch brought by the change of light, and personally experiencing the characteristics of various products.




An interactive script
This dual-path design is a spatial translation of the viewing-performance relationship, which deconstructs the one-dimensional display logic of traditional showroom and instead forms an interactive perceptual experimental field. When visitors transform from observers to performers, the light environment parameters respond dynamically, forming a spatial script with time variables.




In the Undersky showroom, through the three-level narrative structure of “perception-cognition-resonance”, we present the originally abstract light in a perceptible and touchable way in a specific space. The product is no longer an isolated exhibit, but is integrated into the plot of each scene and becomes an anchor of emotional memory. While experiencing the light effect, visitors can also deeply feel the story and value behind the brand.
3. Ritual of Light
Origins and evolution
The Ritual of Light forms the climax of the visit. A circular space evokes the origins and evolution of light: the faint glow of fire, the night sky, sunlight passing through a forest and ripples of reflected light on water.
Nature reimagined
Once, light was like a mysterious walker, shuttling through every corner of life. It is invisible and elusive. And the natural force that was uncontrollable in the past suddenly became visible and tangible here! The sun and the moon shine together, the sea of stars, the passage of time is perceived through the flow of light and shadow, the shape of light is touched through the misty fog, and it can be carefully held in the palm of the hand.
Light and emotional wellbeing
“Light and Shadow Therapy” builds an immersive emotional healing space through multi-level dynamic light effects, setting up multiple modes such as “Natural Breathing”, “Starry Sea Wandering”, and “Forest Whispering”, simulating the complete circadian rhythm from dawn to dusk, and projecting dynamic water ripples and star track light effects on the curved wall. Visitors’ footsteps will trigger ripples of light particles, and the voice decibels will control the brightness of the light color in the area, forming a healing closed loop of human-light interaction. “Meditation Light Dome” uses a 360° ring light band to simulate the slow gradual change of human breathing frequency, and cooperates with hidden directional speakers to broadcast natural white noise, creating the mood of the space through the synergy of vision, hearing, and smell.


4. Forms of Light
Technology and art
PMT Partners used the optical principles of light refraction and scattering to design a series of light installations. These installations imaginatively visualize the originally abstract and invisible light, transforming it into rich and colorful colors and unique shapes, guiding visitors to discover the wonders of light under different carriers.






A prism separates natural light into spectral colours, using geometry to reveal its wavelengths. The showroom also translates UNDERSKY’s Golden Light technology into an installation. Optical instruments become works of art, giving laboratory data a more tangible and poetic form.
