Multimedia system for advertising projection

Abstract

The utility model relates to the field of multimedia systems for the visual presentation of advertising content, and more specifically to a multimedia system for advertising projection, intended for the reproduction of advertising content, which will find application in visual advertising presentations, interactive product positioning, commercial communication, marketing installations, event advertising, facade and interior projection, as well as in other applications where automated control of a light image on a screen, wall, facade, or other projection surface is required. The multimedia system for advertising projection includes an electronic user device (1) connected to a microcontroller (2), which is functionally connected to at least one laser (3) and to at least one proportional-integral-derivative controller (6). The proportional-integral-derivative controller (6) is connected to at least one galvanometer (4) on which a mirror (5) is mounted, positioned to reflect light from the laser (3) toward an image projector (7). Each mirror (5) is multilayered and has at least a reflective layer, a gain layer, and a finned cooling layer.
