A dousing or light blocking method and device for controlling the transmission of sunlight includes a plate of transparent material, having one flat, vertical or nearly vertical, surface and an opposite at least partially inclined surface, the latter facing the sun. The plate is oriented and located with respect to the sun in a predetermined period of the sun path, so as to prevent direct sunlight from getting through the plate in a desired and predetermined year season or period without interfering with the transmission of diffused light. |
