Abstract
The invention discloses a stepless light-transmittance regulation device of an aircraft porthole. The stepless light-transmittance regulation device comprises a polarizer, a polarization analyzer and a driving device, wherein the polarizer and the polarization analyzer are transmission type polarizing films, and are arranged on the same side or different sides of window glass of the aircraft porthole in parallel respectively; the driving device is used for driving the polarizer or the polarization analyzer to rotate. A polarizing film has functions of shielding and transmitting or reflecting incident light, and can transmit or reflect one of longitudinal light and transverse light. The transmission type polarizing films can transmit one of longitudinal light and transverse light. The two transmission type polarizing films are arranged on the same side or different sides of the window glass of the aircraft porthole, and the driving device drives one of the two transmission type polarizing films to rotate, so that the light transmittance of natural light transmitted from the exterior of the aircraft porthole to the interior of an aircraft can be regulated in a stepless manner, the aim of integrally changing the light transmittance of the aircraft porthole is fulfilled, and the comfort of passengers in the aircraft is remarkably improved.
Description
Technical field
