Benefits of technology

This patented technology allows an AC powered fluorescence bulb (FL) to convert its electrical signal back into usable power that powers other electronic devices like LED lights or liquid crystal displays on their screens. It uses a special device called a converter transformer to reduce impedances between different parts of the system while still allowing enough space within them to store more energy than before being wasted during operation. By connecting this transformation element directly to the input side of another component called a load cell, there are fewer components needed compared to previous designs, resulting in improved performance and reliability.

Problems solved by technology

This patents describes different ways how to design a reliable LED (light emitting diode) driving circuit without causing instability or damage from overvoltage conditions caused during normal operations. Current solutions involve complex structures involving various components such as transistor elements, resistors, inductive reactances, etc., leading to increased energy usage compared to traditional designs due to higher voltages needed per unit length of time. Additionally, there may also be limitations on the amount of electricity supplied through each component, making it difficult to maintain consistency across all parts of the device's performance.
