Title: Wilhelmus H. Langeslag: Discharge Lamp Circuit Inventions

Introduction

Wilhelmus H. Langeslag is an inventor associated with Eindhoven, the Netherlands. His work includes inventions concerning high-frequency circuits for operating discharge lamps. He is credited with 2 patents and is associated with U.S. Philips Corporation.

Latest Patents

Langeslag’s listed patents focus on coordinating a lamp’s power feedback circuit and electrode preheater through an antiboost switch.

“Discharge lamp device having a preheating electrode circuit” describes a circuit arrangement that disables the power feedback circuit before the lamp ignites and enables it afterward. The antiboost switch also activates the electrode preheater before ignition and disables it once the lamp has ignited.

“Discharge lamp with heating electrode circuit” describes the same central approach: using the antiboost switch to control both the power feedback circuit and the electrode preheater across the lamp’s ignition cycle.

Career Highlights

Langeslag’s listed inventions address the operation of discharge lamps, with particular attention to managing preheating and power feedback during ignition. This shared circuit-control approach is reflected in both of his listed patents.

Collaborations

His listed coworkers include Paulus P. Arts and Jurgen M. Willaert. The available information associates Langeslag with U.S. Philips Corporation.

Conclusion

Wilhelmus H. Langeslag’s two listed patents center on a coordinated circuit design that preheats discharge-lamp electrodes before ignition and adjusts circuit operation after ignition.
