The projection distance is positively correlated with the pattern size. When the distance increases by 1 meter, the diameter of the pattern expands by about 0.32 times (the lens ratio is 1:0.32, and the proportion of different lenses is different) (formula: the pattern diameter is ≈ the projection distance × 0.32). For example, at a distance of 3 meters, the pattern is about 0.96 meters in diameter.
Focal Length
A telephoto lens magnifies the pattern, but needs to balance clarity. Short focal length is suitable for dense projection in small Spaces，13°lens(1:0.22), 20°lens(1:0.32), 25°lens(1:0.42), 30°lens(1:0.52), 45°lens(1:0.87), 47°lens(1:1).
Product Advantage: The COLIFINE gobo Projector series provides a wide range of lenses with different proportions, which can be changed to flexibly adapt to different scenes.
The standard pattern size (e.g. Ø60mm/Ø90mm) directly affects the projection range.
Compatibility: Our Gobo projectors support mainstream sizes and are available for customization.
Ambient Light
Strong light environments require higher lumens to keep the pattern clear.
gobo projector wattage
The high wattage gobo projector reduces edge blur and makes logo patterns clearer. Especially suitable for complex LOGO design.
2.How to Adjust Logo Projection Size: 2 Practical MethodsPhysically adjust projection distance
Downsize: Place the device close to the projector surface
Enlarge size: Extend the device distance while ensuring adequate brightness
Change lens with different proportions
1.Choose lenses of different proportions to enlarge or smaller patterns.
2.Available in 6 different ratios, the gobo projector is equipped with 20°lens (1:0.32) by default.
13°lens(1:0.22), 20°lens(1:0.32), 25°lens(1:0.42), 30°lens(1:0.52), 45°lens(1:0.87), 47°lens(1:1)
3.Why Choose Professional Gobo Projectors

High compatibility: Support for metal/glass Gobo chips, high temperature resistance and up to 5000 hours of life.
Environmental adaptation: The IP67 waterproof model is suitable for outdoor advertising and stage effects
4.FAQ
Q：Can I scale the projected size of any LOGO freely?
A: Yes! With the combination of “distance + zoom + lens” adjustment, our devices can achieve 20%-300% size change while maintaining high-definition picture quality
Q：How to calculate the projection size at a specific distance?
A: Default 20°lens (1:0.32) Use the formula diameter ≈ distance ×0.32, or visit the official website：COLIFINE GOBO PROJECTOR
