Latest Patents

Janice holds 1 patent for her invention titled "Mercury free discharge lamp with zinc iodide." This compact fused silica, electroded HID lamp is designed specifically for automotive forward lighting and contains no mercury. The lamp operates at approximately 40 volts, achieved by vaporizing zinc iodide instead of mercury. The design allows for a balance between voltage and luminous flux through the careful selection of the sodium scandium (Na:Sc) molar ratio, which ranges from 4.5:1 to 6:1. Additionally, the zinc iodide (ZnI) dose of 2 to 6 micrograms per cubic millimeter ensures compliance with North American, European, and Japanese automotive color specifications for white light. The voltage can be adjusted according to the zinc iodide doping level without significantly affecting the visible spectrum provided by other known dopants.
