Multiple circuit variable light transmission glazing system
The demand for automotive glazings, on which the intensity of the light transmitted can be controlled by the user, has been increasing as the public becomes more aware of the technology. The most common methods employed to make such glazings utilize Suspended Particle Devices (SPD) and Polymer Dispersed Liquid Crystal (PDLC) films. With both, the light transmission of the glazing changes in response to an alternating current electrical field. A problem with this technology is that the voltage required is far higher than that of the typical automotive electrical system. The disclosure provides a touch potential safe, small, lightweight and inexpensive means for controlling the light transmission of multiple glazing circuits by combining a single flyback voltage converter with multiple variable amplitude sinewave generators all coordinated by a micro-controller.
