Device for examining weather resistance and light-fastness

摘要

The present invention provides a device, using which sample bodies can be examined by exposing them to highly energetic radiation energy, so that a uniform radiation density is achieved over the entire surface area of the sample body. In this case, the internal space of a test chamber (1) is divided by a glass filter (2) into a lower section which forms a sample chamber (3) and an upper section which forms a lamp chamber (4). The sample chamber (3) has a sample base-plate (6) which is arranged at a predetermined distance from the glass filter (2) and on which sample bodies (19) are arranged. The lamp chamber (4) has a lamp (8) which is bent to an angle and permits a uniform radiation density over the entire surface area of the sample base-plate (6), the lamp (8) being arranged at a predetermined distance from the glass filter (2). A fan (11) for supplying cooling air to cool the internal space of the lamp chamber (4) and the lamp (8) is furthermore provided. <IMAGE>
