ABSTRACT:
The invention provides a panel unit of controllable radiation transmissivity, including a housing constituted by a front, radiation-receiving panel and a rear panel, the panels being spaced apart and connected to one another by connecting means; a plurality of rotatable radiation-blocking members disposed between the front panel and the rear panel, the members being rotatable from one angular position in which the radiation-blocking members are adapted to substantially block the passage of light through the panel unit, to a selectable plurality of other angular positions in which the radiation-blocking members are adapted to provide a plurality of differing radiation transmissivities; characterized in that first guiding surfaces for the rotatable radiation-blocking members are disposed inside of, and extend across, the housing.
