摘要 |
The present invention relates to a device for regulating the passage of energy through a light-transmitting area, comprising a first polarisation layer, a second polarisation layer and a switching layer which is arranged between the two polarisation layers and changes the polarisation properties of polarised light as a function of temperature, where the two polarisation layers are characterised by a suitable choice of their transmission in the transmission direction and their degree of polarisation. The invention furthermore relates to a process for the production of the device according to the invention and to the use of the device for influencing light transmission and/or the passage of energy into an interior as a function of temperature. |
