Decorative Diffusers for Sun Tunnels: Soft, Even Light

The Sun Tunnel brings daylight into a building, but how it is perceived in a room depends on the VELUX decorative diffuser.

How VELUX Decorative Diffusers Work

In the VELUX Sun Tunnel accessories system, the diffuser is part of the standard configuration. It closes the light channel opening and defines the base distribution of daylight in the space.

Decorative diffusers are interchangeable optical panels that are installed in place of the standard element. They are designed specifically for Sun Tunnel Skylight Accessories and operate inside the ceiling module without affecting the light channel or the main structure of the system.

Each option has its own optical surface structure. Some use a micro-textured relief, while others use linear waves or prismatic geometry. These surface patterns influence how light is distributed, creating different lighting effects.

Natural Lighting Design Ideas

Micro Fresnel

A micro-structured surface is used to control the direction of the light flow. The light remains focused and free of strong glare. This option is suitable for spaces where stable and even lighting is needed throughout the day.

Triple Wave

The diffuser is based on a wave-like optical geometry. A subtle pattern appears on the ceiling and changes with the viewing angle.

Brushed Metal

Works through a reflective surface with a pronounced texture. The ceiling diffuser becomes a visually active element of the interior. Light is distributed evenly, while the surface gains a distinct visual accent.

Prismatic

Uses a prismatic structure to redistribute light across the entire output area. The lighting becomes even, without local brightness variations. The effect is especially noticeable in narrow and elongated spaces.

Neutral Light

Makes the passing light feel warmer and softer, especially in areas without side natural lighting.

How Different Diffusers Shape Light

The same Sun Tunnel can produce completely different visual results depending on the selected decorative diffuser.

Micro Fresnel creates a defined light structure. Prismatic distributes light evenly across the surface without emphasis. Triple Wave adds a soft dynamic to the light pattern. Brushed Metal turns the ceiling element into a distinct part of the interior. Neutral Light makes the light in the space warmer and more comfortable.

Installation and Replacement of the Diffuser

The decorative diffuser is installed in the Sun Tunnel ceiling module in place of the standard insert. It easily locks into position and becomes part of the light output element in the space.

Replacement is simple. The internal insert is removed and the decorative element is installed in its place. The light channel and the entire Sun Tunnel system remain completely unchanged.

VELUX decorative diffusers make it possible to change the character of lighting without affecting the system. Replacing a single element is enough to create a new perception of the space.
