Expert Guide: How to Create Effective Gobo Projection.
Light can do more than illuminate a space. It can communicate, guide, decorate, and strengthen a brand. Gobo projection is one of the most versatile lighting techniques for achieving exactly that. Whether used in a boutique hotel, museum, gallery, retail environment, or exhibition stand, a well-executed projection can leave a lasting impression while requiring minimal physical intervention.
With Arte, Karizma Luce offers a compact architectural gobo projector designed specifically for interior applications that require precision, elegance, and flexibility.
What is a gobo projection?
A gobo is a small glass or metal template containing a logo, text, pattern, symbol, or graphic. Inside the luminaire, light passes through this template and is focused by projection optics onto a wall, floor, ceiling, or other surface.
Unlike printed signage, a gobo projection uses light itself as the medium of communication. Therefore, the image can be changed, removed, or updated without affecting the architecture.
This makes gobo projection particularly attractive for hospitality projects, museums, galleries, boutiques, retail environments, and temporary exhibitions.
How does Arte work?
Arte combines an LED light source with a precision optical system and a custom gobo. The optical system projects a sharp image while allowing focus adjustment to achieve the desired result.
Available with an adjustable beam angle of 20° to 30°, Arte can create both compact and larger projections depending on the installation distance. The luminaire delivers up to 420lm, making it suitable for architectural environments where visual comfort and integration are more important than extreme projection distances.
Choosing the right projection distance
One of the most important design decisions is the distance between the projector and the projection surface.
For Arte, the practical projection range typically ranges from 1m to 10m.
The table below shows the approximate projection diameter and theoretical average illuminance without a gobo installed. The lux values assume that the full luminous flux is projected evenly across the illuminated surface.
| Distance | Diameter 20° | Lux 20°* | Diameter 30° | Lux 30°* |
|---|---|---|---|---|
| 1m | 0.35m | 4,300lx | 0.54m | 1,860lx |
| 2m | 0.71m | 1,075lx | 1.07m | 466lx |
| 3m | 1.06m | 478lx | 1.61m | 207lx |
| 4m | 1.41m | 269lx | 2.14m | 116lx |
| 5m | 1.76m | 172lx | 2.68m | 74lx |
| 6m | 2.12m | 119lx | 3.22m | 52lx |
| 8m | 2.82m | 67lx | 4.29m | 29lx |
| 10m | 3.53m | 43lx | 5.36m | 19lx |
*Theoretical values calculated from 420lm without a gobo.
For most hospitality, retail, gallery, and exhibition applications, the optimal projection distance is usually between 2m and 6m. Within this range, Arte achieves an excellent balance between image size, brightness, and sharpness.
Understanding the impact of the gobo
The values in the table above represent the luminaire’s maximum theoretical output. In practice, a gobo blocks part of the light.
The actual illuminance depends on the artwork itself. For example, a simple logo with large transparent areas allows more light to pass through, making it appear brighter. But a detailed graphic, dense pattern, or logo with large dark areas blocks more light and reduces the projected illuminance.
As a general guideline, the visible illuminance of the projected image can be significantly lower than the values shown above. However, this is completely normal and should be considered during the design phase.
For this reason, it is always recommended to evaluate the projection size, viewing distance, and ambient lighting conditions together rather than focusing solely on lumen output.
Designing with light
Gobo projection offers designers a unique way to communicate through light without adding physical elements to the architecture. Such as logos, wayfinding, decorative patterns and temporary branding, the technique combines flexibility with minimal visual impact.
With its compact dimensions, adjustable optics, and architectural appearance, Arte provides a refined solution for interior applications where projection quality, integration, and design freedom are equally important.
