Latest Patents

John F. Hall holds a patent for a "Discharge lamp with automatic shut off." This invention features a high-intensity discharge lamp equipped with a safety switch that automatically turns off the lamp upon rupture of the outer envelope. The switch is ingeniously designed with a carbon rod located in the interior space between the arc tube and the outer envelope. This rod is connected in series with one of the electrodes, allowing the current flow to maintain it at an elevated temperature during the lamp's operation. In the event of an outer envelope rupture, the carbon rod oxidizes and falls, effectively interrupting the electrical path to the electrodes.
