Latest Patents

One of Shen's notable patents is the "Remote control of fluorescent lamp ballast using power flow interruption." This innovative dimming ballast system allows for the control of light output from fluorescent lamps via a remote source. The ballast output voltage is regulated through a voltage control feedback loop, enabling the dimming function by varying the set point of the control loop. The remote control signal is coded by briefly interrupting the current flow to the ballast, which is then processed digitally by a microcomputer. This technology generates information to adjust the control set point. Additionally, circuit means are incorporated to manage the filament voltage of the fluorescent lamps, ensuring that as the lamps are dimmed, the filament voltage is either maintained or slightly increased. This feature prolongs lamp life and stabilizes the light output.
