Latest Patents

One of Feng-Kang Hu's latest patents is focused on the remote control of fluorescent lamp ballasts using power flow interruption. This innovative dimming ballast system allows the light output of the lamp to be controlled by a remote source. The ballast output voltage is regulated through a voltage control feedback loop, with the dimming function achieved by varying the set point of this control loop. The remote control signal is coded by interrupting the current flow to the ballast for a short period. This signal is processed digitally by a microcomputer, which generates information to adjust the control set point. Additionally, circuit means are provided to control the filament voltage of the fluorescent lamps. As the lamps are dimmed, the filament voltage is maintained or slightly increased, thus prolonging lamp life and stabilizing the lamp light output.
