Title: Innovations of Dao Hong Wang
Introduction
Dao Hong Wang is an accomplished inventor based in Hong Kong, China. She has made significant contributions to the field of automotive lighting technology. With a total of 2 patents, her work focuses on enhancing the efficiency and performance of high-intensity discharge (HID) lamps in vehicles.
Latest Patents
One of her latest patents is titled "HID ballast with integrated voltage multiplier and lamp temperature compensation." This invention addresses the temperature compensation of HID lamps in automobiles. It involves a method to account for the temperature of the HID lamp to drive it at appropriate power levels under varying conditions. The voltage across a capacitor in the temperature compensation circuit is sensed and used as a command signal to anticipate lamp temperature. Consequently, the reference power to the HID lamp is modulated based on the lamp's temperature. The lamp is driven with a higher power setting when cold and a lower power setting when hot, ensuring optimal performance.
Another notable patent is the "Method and system for automatically controlling power supply to a lamp of a vehicle." This system includes a detection module that identifies whether the vehicle is stationary or in motion. The controller receives signals from the detection module and adjusts the power supply to the lamp accordingly. When the vehicle is stationary, the power supply is reduced to conserve energy. Conversely, when the vehicle is in motion, the power supply is restored to its original level, enhancing energy efficiency.
