Title: The Innovative Mind of Dennis M. Capewell

Introduction

Dennis M. Capewell, an esteemed inventor based in Penllyn, Pennsylvania, has made significant contributions to the field of lighting technology. With a portfolio of 11 patents to his name, Capewell's work primarily focuses on enhancing the performance and efficiency of gas discharge lamps through innovative dimming systems.

Latest Patents

Two of Capewell's most notable recent patents reflect his commitment to advancing lighting technology. The first, titled "Gas Discharge Lamp Dimming System," presents a revolutionary dimming system that provides a time-varying current from a power source between the electrodes of a gas discharge lamp. This system also includes high-frequency, low-level current to sustain the electric discharge when the varying current alone is insufficient. This innovation reduces the starting stress on the lamp, extending its lifespan by delaying arc discharge formation during startup until the electrodes have been adequately heated. The system is compatible with standard magnetic ballasts, enabling a full range of dimming from 3 to 100 percent of light output, all while minimizing flicker and lamp dropout.

The second patent, "High Frequency Gas Discharge Lamp Dimming Ballast," addresses the challenge of dimming at very low light outputs. This ballast can dim to approximately 1 percent of its rated output in a consistent manner, ensuring that multiple dimming ballasts connected in parallel produce identical light illumination at lower settings. It achieves this through advanced current sensing and control methods, ensuring optimal lamp operation even under low illumination conditions.
