Jacob Schlejen is a notable inventor based in Morgantown, WV (US). He has made significant contributions to the field of illumination technology, holding a total of 4 patents. His work focuses on advancements in electrodeless low-pressure discharge lamps and related technologies.

Latest Patents

Among his latest patents, Jacob has developed an illumination unit that comprises an electrodeless low-pressure discharge lamp and a high-frequency power supply unit. This innovative lamp features a gastight closed discharge vessel with an ionizable fill and a coil with turns of a primary and a secondary winding around a core of soft-magnetic material. The power supply unit is designed with input terminals and a first output terminal that is electrically neutral with respect to ground, connected to the primary winding. During nominal operation, the primary winding excites a high-frequency magnetic field that maintains an electrical discharge in the discharge vessel. This process induces a potential drop in the secondary winding, facilitating the lamp's ignition. Additionally, his electrodeless low-pressure discharge lamp includes a translucent discharge vessel made of glass containing at least 5 weight % sodium, which encloses a discharge space filled with mercury. This design incorporates a device to maintain an electrical discharge and an auxiliary radiation source to ensure a relatively short ignition time.
