Abstract

Ein Leuchtpult wird vorgeschlagen, welches aus einem Hohlkörper (1) besteht, an dessen Boden (2) und Seitenflächen (3) innenseitig eine reflektie­ rende Schicht angebracht ist und in dem als Lichtquelle (4) eine Leuchstoffröhre angeordnet sowie die Lichtaustrittsöffnung mit einer Streu­ fläche (5) versehen wird. Es wird vorgeschlagen, in Lichtausbreitungsrichtung vor der Streufläche (5) eine teildurchlässige, teilreflektierende Schicht (6) anzuordnen, deren Lichtdurchlässig­ keit zur gleichmäßigen Ausleuchtung der Licht­ austrittsöffnung mit wachsendem Abstand von der Lichtquelle (4) zunimmt.
