A gobo projector is a lighting fixture that projects a pattern, image, or text using a gobo (a template with a cut-out design). This type of lighting is widely used in theater, events, advertising, and architectural lighting . The term "gobo" likely comes from the English expression "Go Between" or "Goes Before Optics." This refers to the placement of the gobo in the lamp , namely between the light source and the lens.
1. How does a Gobo projector work?
A gobo is a metal or glass template with a cutout design. When a powerful light source shines through the gobo, it projects the pattern onto a surface, such as a wall, stage, or floor.
📌 Important parts of a Gobo Projector:
- Gobo holder → Contains the template.
- Powerful light source (LED, halogen or HID lamp) → Provides a bright projection.
- Lens → Determines the sharpness and focus of the projection.
- Zoom and Focus Options → For adjusting size and brightness.
💡 Example: A theater production might use a gobo projector to project a moon, tree branches, or a cityscape onto the stage.
