Patent

CA 2335251

The invention provides a panel (2) of controllable radiation transmissivity, including a plurality of tubular cells (4), in at least some of which cells is rotatably mounted at least one radiation-blocking member (6), at least one portion of at least one surface of which is substantially opaque, and means (8) for rotating the radiation-blocking member (6) inside the tubular cells (4), wherein the radiation-blocking member (6), when rotated, is adapted, in at least one angular position, to substantially block the passage of radiation through the panel (2), and in a plurality of other, selectable, angular positions, to provide a plurality of differing radiation transmissivities.

La présente invention concerne un panneau (2) à transmissivité de rayonnement réglable qui comprend une pluralité de cellules tubulaires (4) dont au moins certaines contiennent à l'intérieur au moins un élément (6), monté rotatif, qui bloque les rayonnements par l'intermédiaire d'au moins une portion d'une, au moins, de leurs surfaces, pratiquement opaque, et des moyens (8) de mise en rotation de l'élément bloqueur de rayonnement (6). Cet élément (6) est conçu de manière à empêcher, lors de sa mise en rotation, pour au moins une position angulaire, le passage de rayonnement à travers le panneau (2), et à permettre, dans une pluralité d'autres configurations angulaires que l'on peut sélectionner, une pluralité de transmissivités différentes de rayonnement.
