#The invention will be described in greater detail hereinafter with reference to the illustrative embodiments shown in the drawings, in which:

#FIG. 1 shows a greenhouse provided with the strip assembly according to the invention;

#FIG. 2 shows detail II from FIG. 1;

#In FIG. 1, reference numeral 1 denotes a greenhouse. The greenhouse consists of a number of roof sections 2 and each roof sections is constructed from panels 3. The panels 3 are preferably oriented such that the angle which the panels form with respect to incident solar radiation at the moment at which the protection has to be most effective is approximately 90 degrees.

#FIG. 2 shows a detail of the panel 3. The panel consists of two remote translucent plates 4 and 5. The plates may be glass plates but also plastics materials plates and the like. The strip or slat assembly according to the invention is attached between these plates. The strip assembly consists of a number of translucent further electrodes 6 and strips or electrodes 10-13. In FIG. 2, the strips 10-13 are shown in all cases in a different position for the sake of clarity. The further electrodes 6 are configured as grid and connected to the first pole of a schematically illustrated voltage source, whereas the strips 10-13 are connected to the other pole of a voltage source via the line 8 and switch 7. The voltage source may be located close to the panel and be any construction known in the art with which high voltage can be generated. The voltage source can be operated remotely, i.e. the switch 7 can be a remotely operated switch.

#The particular embodiment of the strips allows the strips to be electrostatically drawn toward the further electrodes or driven away therefrom respectively. The movement will also be influenced by gravity. In the presence of a potential difference as shown in FIG. 2, the strips will move toward the further electrodes 6. With the same polarity on the strips 10-13 and further electrodes 6, repulsion will take place. However, it is also possible to give the strips a shape memory, as a result of which the strips move, when no voltage is applied, in a specific direction, preferably in the direction for the complete passage of light (perpendicular direction). This position can also be obtained by gravity.
