ABSTRACT:
A louvre assembly between two transparent covers of a housing comprises lightweight louvres suspended and pivoted by lightweight filaments. A counterbalanced beam for pivoting the louvres can be operated by an electrical driving arrangement such as one including a piezoelectric bimorph driver. The electrical power for operating the driver may be obtained from solar cells. A louvre guide system spaces the louvres from the transparent walls of the housing and guides the louvres.
