Projection arrangement, especially for projecting images onto large surfaces, has coupling devices designed so projection regions of 2 coupled projection modules butt together or partially overlap

摘要

The arrangement has a projection surface (1) and at least two separate projection modules (2-5), each containing an image generating unit and a projection unit in a housing (52-55) with a coupling device (6-8). Each projection module projects an image onto the projection surface in an associated projection region and the coupling devices are designed so that the projection regions (72-75) of two coupled modules butt together or partially overlap each other.
