Title: Lodewijk H Meessen: Innovator in High-Pressure Discharge Lamp Technology

Introduction

Lodewijk H Meessen is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of lighting technology, particularly in the development of high-pressure discharge lamps. With a total of 2 patents to his name, Meessen's work has had a considerable impact on the efficiency and performance of lighting systems.

Latest Patents

One of Meessen's latest patents is for an operating circuit for a high-pressure discharge lamp. This circuit arrangement is designed to operate a high-pressure discharge lamp in conjunction with a controlled current limiter. The control signal used in this arrangement is composed of both a lamp-voltage-dependent signal part and a lamp-current-dependent signal part. Notably, the absolute value of the lamp-current-dependent signal part is smaller than that of the lamp-voltage-dependent signal part. This innovative circuit provides rapid control, ensuring that the lamp voltage remains substantially constant.

Another significant patent by Meessen is for a high-pressure sodium vapor discharge lamp. This lamp features a ceramic discharge vessel with a constant inner diameter over its length. The design includes electrodes positioned opposite each other at a specific distance, allowing the lamp to emit white light while consuming a maximum power of 50 watts. The lamp's high efficiency and excellent color rendering are attributed to the optimal distance-to-length ratio of the electrodes.
