Design around the room
Review your drawings, dimensions, ceiling allowance and intended use. Develop the shape, lighting mood and control requirements; DIALux simulation can support the lighting proposal where appropriate.
Barrisol Lighting | Design, Supply & Installation
BARRISOL LIGHTING · 光の天井
Light becomes
architecture.
A luminous ceiling shaped around your space. KOYAMA combines lighting design, product supply and professional installation to bring your vision into the room.
DESIGN · SUPPLY · PROFESSIONAL INSTALLATION
Concept visualisations of the same space. Colour-temperature appearance is illustrative; screens, materials, daylight and the specified lighting system affect the final result.
ONE SPACE, DIFFERENT ATMOSPHERES · 光の表情
From warm welcome
to cool clarity.
See the lighting mood transition from 3000K warm white through 5000K to 6000K cool white. A tunable-white design lets you adapt the atmosphere to the way the space is used.

Animated concept demonstration, not footage of a completed installation or a calibrated colour-temperature measurement. To achieve adjustable colour temperature, specify tunable-white LEDs with compatible drivers and controls. Fixed-colour-temperature systems do not provide this function.
THE LIGHTING PRINCIPLE · 面の光
A surface of light.
A considered atmosphere.
A translucent stretch membrane diffuses the light sources placed behind it, turning a ceiling or feature area into a luminous surface. The light becomes part of the architecture, with the shape and scale developed around the room.
We plan the LED layout, available ceiling depth, membrane and perimeter detailing together. This helps manage visible hotspots, brightness differences and the practical need to access drivers for maintenance.

Your architecture.
Your shape of light.
Go beyond a standard rectangle or circle. Flowing curves, elongated forms, geometric outlines and bespoke compositions can be developed around your interior concept.
We work from your ceiling plan and design intent to refine the contour, scale, framing and illuminated finish. The final shape is coordinated with site conditions, structural support, membrane selection and practical installation requirements.
SUPPLY & INSTALLATION · 設計から施工まで
A professional team.
From proposal to installation.
KOYAMA supplies and installs luminous stretch-ceiling lighting, with a professional team to carry out the work. We support the project from lighting design and specification through installation and final lighting adjustments.
Coordinate the complete system
Specify the membrane, framing, LED arrangement, drivers and controls as a coordinated solution. Our professional team handles installation, with site and electrical requirements agreed for the project.
Adjust and hand over
Review the illuminated finish and selected controls, make lighting adjustments and explain operation and access for future maintenance.
MADE FOR YOUR SPACE · 空間に合わせて
One idea. Many possibilities.
Homes & private interiors
A luminous feature above a dining area, living space or circulation zone, with the atmosphere designed around daily life.
Offices & reception spaces
A clear architectural gesture for meeting rooms, client areas and workplace interiors, coordinated with task and accent lighting.
Retail & hospitality
Custom luminous forms for showrooms, boutiques and guest spaces, developed to complement the interior and its focal points.
Before we begin.
Can I choose 5000K, 6000K or adjustable colour temperature?
Tell us which effect you prefer. We can develop a fixed-white or tunable-white specification around the project. Adjustable colour temperature requires suitable LEDs, drivers and a compatible control system; the agreed quotation will identify the included components and control functions.
Is this a standard-size light I can order directly?
This is a project-based supply-and-install service. Shape, dimensions, membrane specification, light output, installation conditions and controls are confirmed in your proposal before ordering. Pricing and lead time are quoted for the agreed scope.
How much ceiling space is required?
There is no single depth suitable for every design. LED spacing, diffusion distance, structural support, wiring and maintenance access need to be reviewed together. Share the available ceiling void and any site restrictions so we can assess a practical arrangement.
LET’S PLAN YOUR PROJECT · ご相談
Show us your space.
Send us a ceiling plan or site photographs, the approximate illuminated area, available ceiling depth, project location and target completion date. Let us know whether you prefer 3000K, 5000K, 6000K or tunable white, and whether smart control is required.
