Latest Patents

One of Chan's latest patents is the "Passive Anti-Arcing Protection Device for Fluorescent Lamp Ballast." This invention features a passive anti-arcing protection component designed for electronic ballasts of fluorescent lamps. The component consists of a bridge-rectifier-resistor-capacitor network, which includes at least a diode, a resistor, and a capacitor. The circuitry is electrically connected to the ballast at the lamp side, providing a low-resistance redirection path for sudden energy changes. When an arcing condition is imminent, this protection circuitry absorbs the spark energy, effectively ceasing the arcing condition.

Another significant patent is the "Current Leakage Protection Device for LED Applications." This electronic circuit is designed for driving an LED device and includes an LED, a driver for supplying current to the LED array, and one or two current detection modules. These modules are connected to the LED array to detect current levels and send signals to the driver. Upon detecting a fault condition on either side of the LED array, the driver immediately breaks the circuit based on feedback from the current detection modules.
