Abstract
An electric window dimming device for reducing the light transmission of a window for an aircraft. The electric window dimming device comprises a capacitance. The electric window dimming device is adapted for being connected to the capacitance and to a primary energy source that provides energy. If the primary energy source fails, the capacitance supplies energy for electric window dimming device.
