Arrangement for image representation in rear projection-television set, has projection optics, where light comes from lighting device, over third partial optics at angle, lying at common Z-axis of former and latter partial optics

摘要

The arrangement has projection optics (2), which comprises two partial optics lying on a common Z-axis, where the other partial optics is formed as field lens provided for lighting. The light comes from a lighting device (1), over a third partial optics at an angle, lying at common Z-axis of the former and the latter partial optics, as well as over a deflecting element into the latter partial optics. An off-axis mirror (5) and deflecting element (3,6), which serves as a convolution of optical path, are provided in the optical path of a front area of the projection optics.
