Patent attributes
The present invention discloses an improved light transmitting plastic panel (100) used in buildings for providing a variable daylight either during a day or in various areas of the building. The light transmitting plastic panel (100) consists of two transparent plates (102A, 102B) and a plurality of transparent hollow cells of V-type (104A, 104B) and rhombus shaped cells (106) located in between these plates (102A, 102B). In particular, a structure of the hollow cells is a repetitive sequence of one rhombus cell (106) in between two V-type cells (104A, 104B). Further, some of the hollow cells are made opaque with a predetermined pattern. With this specific structure, the variable daylight is achieved based on a time of day. In another aspect of the invention, differential daylight is provided for different areas of the building by forming a non-continuous flow pattern of opaque hollow cells across the length of the light transmitting plastic panel (100).
