ABSTRACT:
A light valve system wherein particulate material is introduced into a normally light-transmitting cavity to restrict light transmission through the cavity from one side to the other. The cavity may be partially or totally filled with a particulate material depending on the degree of light restriction desired. The particulate material may comprise a thermal insulating material which restricts heat transmission as well as light transmission through the cavity. The use of the present light valve system in a greenhouse structure is described.
