Abstract
The present invention relates to variable optical transmission windows and window panels (VLTP) which are used for architectural applications such as building entryway systems and windows. The optical transmission of the VLTPs is reversibly changed by applying an electrical voltage. The emphasis is placed on doors which can be placed in the field without having certified technicians. The doors and windows having these VLTPs may also have other electronic devices which provide added user functionality.
Claims22
A building door comprising at least one variable light transmission panel (VLTP), wherein the VLTP is configured to change optical transmission upon application of an electric voltage thereto, and comprising a power modulator which provides the electric voltage to the VLTP, wherein the power modulator is configured to receive power from a power adapter, wherein a received voltage profile received by the power modulator is different from an output voltage profile outputted by the power modulator to the VLTP, and wherein the electric voltage received by the power modulator from the power adapter is less than or equal to 12V.
A building door comprising two or more variable light transmission panels (VLTPs), wherein the VLTPs are configured to change optical transmission upon application of an electric voltage thereto, and comprising a power supply comprising a power modulator and a power adapter, wherein the power adapter supplies power to the power modulator at a voltage of 12V or less, and the power adapter is configured to provide the electric voltage to the VLTPs, and the power modulator applies a different voltage profile to at least two of the VLTPs.
A building door comprising at least one variable light transmission panel (VLTP) which is configured to change optical transmission upon application of an electric voltage thereto, and the door contains:
- (i) a power modulator which provides the electric voltage to the VLTP, wherein the power modulator receives power from a power adapter at a voltage of less than or equal to 12V, which is different from a voltage profile outputted by the power modulator to the VLTP;
- and
- (ii) at least one of the following:
- a) a sensor selected from a temperature sensor, light sensor, or a motion sensor;
- b) an electronic device selected from an electronic lock, camera, doorbell, alarm, or a light.
