Short definition
A projector is an optical-electronic device that casts video signals onto a projection surface. Event technology relies on high-output models ranging from 5,000 to over 50,000 ANSI lumens.
Detailed explanation
Event projectors differ from home models through significantly higher brightness, resolution, and reliability. Three technologies dominate the market: DLP with strong contrast and a compact build, 3-chip LCD with natural color rendering, and laser projectors, which replace lamps with laser sources for longer service life and higher brightness.
Laser projectors have become the standard: instantly ready to use, consistent brightness over their lifetime, and no lamp changes required. Key technical specs include brightness, native contrast, resolution, lens compatibility, and operating noise. Elaborate productions use models with motorized lens shift, zoom, and focus that can be adjusted remotely.
Relevance in this field
Projectors remain an essential tool in event technology, especially for large-format images and projection mapping. Choosing the right model is critical to both the visual result and operational reliability.
Practical example
A stage show uses three laser projectors at 20,000 lumens each with interchangeable lenses: two for the main screen in an edge-blended setup, one for a side screen. Calibration runs through the media server's output management.
