Title: Songling Mao and Fluorescent-Lamp Ballast Innovation.
Introduction
Songling Mao is an inventor based in Shanghai, China. His work includes an electronic ballast design intended to improve fluorescent-lamp starting efficiency and extend lamp life.
Latest Patents
Mao is associated with 1 patent, titled “Electronic Ballast Using Cut and Save Technology.” The invention uses adjusting, output, and control circuits to provide suitable filament preheating while reducing the voltage across the lamp tube, helping prevent glow current during preheating. Once preheating ends, the voltage rises to the lamp’s breakdown level to start the lamp. The control circuit then cuts off the filament’s preheating voltage, reducing power consumption during normal operation.
Career Highlights
Mao is associated with Phi Hong Electronics (Shanghai) Co. Ltd. His patent describes a ballast approach designed to improve electronic-ballast efficiency and extend the operating life of fluorescent lamps.
Collaborations
Mao’s listed coworkers include Kevin Yang and Haoran Zeng.
Conclusion
Songling Mao’s patent focuses on controlling filament preheating and lamp startup to reduce energy use while supporting efficient operation and longer fluorescent-lamp life.
