Stage lighting design is an important part of the stage performance art. In recent years, with the development of digital projection technology and the expansion of its field of art, stage lighting design in the form and content richer. Performance in the application of digital projection technology, the digital video processing, digital video projection and computer lights and other modules combined with digital lights, through the control device on the digital light within a variety of image material chooseion, stacking, cutting and other special effects processing, and then projection To any flat or three-dimensional receiver, can show a variety of video images. It to enhance the artistic effect of the show, to better express the theme of the show.

The use of high-brightness digital light, because it has a rotating orbit lens, you can make the projection of the projector image in the horizontal 250 °, vertical 360 ° range, and the use of the servers trapezoidal correction function to correct the deformation of the Image, so the location of digital lights and hanging the way are quite flexible.

If you want to throw a large screen in the short distance you need to choose the short focus lens, otherwise you need to choose telephoto lens. Under normal circumstances, the use of digital light standard lens specifications are 2.8 ~ 4.5: 1; telephoto lens for the 4.5 ~ 7.3: 1 and 7.3 ~ 11: 1; short focus lens 1.8 ~ 2.6: 1 and so on. Different manufacturers have different lens specifications, but the same usage, mainly based on the stage of the projection media area and illumination requirements to choose.
3 video signal control and transmission
