Latest Patents

Junhui Fei holds a patent for a "System and method for driving light emitting diodes." This invention includes a system with an alternating current (AC) driven LED unit, an AC voltage regulator, and a controller. The AC driven LED unit consists of a first LED and a second LED coupled in reverse parallel. The AC voltage regulator receives AC voltage from an AC voltage source, regulates it according to control signals from the controller, and applies the regulated AC voltage to the LED unit. This allows both LEDs to emit light based on the regulated AC voltage. The method also provides benefits such as restraining voltage fluctuations, reducing total harmonic distortion (THD), improving power factor, offering dimming control, and mitigating flicker phenomena.
