Unit for permanent determining of radiation density, e.g. of daylight, in spherical space and surrounding surfaces

摘要

The unit is used for day light, the scattered and the reflected light as well as an isolated determination of the global radiation. On a spherical cap 2, are carried light receivers, uniformly distributed over the surface. Optical light receivers (3,11) are provided, which stand in working contact with one or more photodiodes across optical light-wave conductors (5). For the determination of the global radiation, a part of the light receiver (11) with its axis aligned parallel to the vertical axis, and a surface unit (2.1) lying horizontally oriented in the region of the top point of the spherical cap, are arranged centrally to the vertical axis of the unit.
