Latest Patents

David P Ball holds a patent for a fluorescent lamp controller. This invention describes a circuit suitable for the instantaneous starting, continuation, and interruption of current through one or more gas-filled discharge tubes, specifically fluorescent lamps. The circuit ensures that the lamp heaters are energized before instantaneous control can occur. A preferred silicon controlled rectifier (SCR) is utilized with a bridge rectifier, allowing for immediate arc striking upon application of gate current. Additionally, a TRIAC can be employed without a bridge rectifier, providing a dual role of pulse-starting and maintaining current, which also facilitates a dimming function. This technology finds applications in 'flashing' advertising signs, general illumination, and signals.
