Often named Z-lampthe reason is clear. The real name is Diplomat. It is the successor of the Decora desk lamp designed by Louis Kalff in the 1950s. This desk lamp was made from the late 60s, early 70s until the 1980s. Same desk lamp, different lampshade. You can find the Decora over here on Vintageinfo.

This “modern” angular lampshade was the redesign for several lamps designed by Louis Kalff in the 1950s. The lampshade was not designed by Louis Kalff, since he retired in 1960. Probably designed under his approval by the Philips design team.

Koninklijke Philips N.V.

Inspired by the fast-growing electricity industry and the promising results of Gerard Philips own experiments to make reliable carbon filaments, Frederik Philips (his father) financed the purchase of a modest factory in Eindhoven, The Netherlands in 1891.  Frederik Philips was a Jewish banker based in Zaltbommel.

In 1895, after difficult first four years and near bankruptcy, Anton Philips joined the company. He was Gerard’s younger brother. With Anton’s arrival, the family business began to expand rapidly. The brothers changed their family business by founding the Philips corporation. They laid the foundations for the later electronics multinational.

In 1930 the first shaver of the Philips company was introduced and was simply called “The Philishave”.

A day before the German invasion in the Netherlands on 9 Mai 1940, the Philips family fled to the United States of America, taking a large amount of the company capital with them.

Operating from the US as the North American Philips Company, they managed to run the company throughout the war. After World War II the company was moved back to the Netherlands, with their headquarters in Eindhoven.

Philips Diplomat Desk Lamp - publicity

“Met de Philips bureaulampen kunt u langer doorwerken, zonder dat uw ogen vermoeid raken. Vergeet echter niet de algemene verlichting aan te brengen: u vermijdt daardoor een te sterk contrast tussen het verlicht deel (uw bureau) en het schemerdonker van de rest van de kamer.”

“With the Philips desk lamps you can work longer without making your eyes tired, but do not forget to apply the general lighting: you avoid too strong contrast between the illuminated part (your desk) and the twilight of the rest of the room.”
