Date Jun. 28, 1990.Arrangement for collecting and emitting light via defined surface areas (25) in order to create a slide. The arrangement consists of a number of transparent plate elements, collector plates (12-15), which are designed to receive incident light at one or more of their surfaces, collector surfaces (17-22), and to emit the received light at one or more of their other surfaces, emission surfaces (28). The collector plates consist of fluorescent material designed to convert received ultraviolet light to visible light. The arrangement comprises a plate (3) which forms a carrier for the slide which is to be presented. The plate elements (12-15) are set transverse to the carrier plate with their light-emitting surfaces (28) bearing against the rear side (29) of the carrier plate. The light-emitting surfaces (28) are situated in strip-shaped intermediate spaces between opaque parts (24) of the carrier plate. |
