life and work

The Berlin clock is probably Binninger's best-known work.

Binninger was a trained watchmaker and electrical engineer at the Bingen University of Applied Sciences . The Eppertshausen operator of the company "Videor" wanted to conquer the world with wristwatches that display the time on the basis of set theory and gave the oversized prototype to the Charlottenburg district for advertising purposes. The plans for the manufacture of the wristwatches were discontinued in view of the development costs for a chip in the order of 100,000 DM. In 1,973 table and wall models of the Berlin clock patented as a display device were produced.

When setting up the Berlin clock , Binninger had not taken into account that the light bulbs often failed due to vibrations from traffic on Kurfürstendamm . Since he was responsible for replacing the light bulbs, he had to rent a pallet truck every time. In total, this resulted in annual costs of around DM 8,000.

So he thought about more durable light bulbs. For economic usability, which is a prerequisite for the granting of a patent, he considered replacing Sig lamps , such as those used in traffic lights , with normal incandescent lamps with twice the nominal output and then dimming their output down. As a result of the now missing blue components in the light, the problem arose that the once green little man in a pedestrian traffic light glows brown. Dimmed far enough, he expected - according to the diagram in his patent - a service life of up to 1,000,000 hours for normal incandescent lamps. On the basis of an article in the magazine Straßen-Verkehrs-Technik , he calculated a theoretically required average service life of the incandescent lamps of 150,000 hours for a target replacement cycle of 12 months with a required failure rate of 2 percent.

He promised an operating time of 150,000 hours for this eternal light bulb or long-life light bulb .

On March 5, 1991, Binninger died in a private plane crash north of Helmstedt. His son and the pilot of the TB10 Tobago were also killed. Since his widow could no longer pay the maintenance costs for the Berlin clock, it was dismantled on Kurfürstendamm in 1995. In 1996, on the initiative of business people, it was set up again in front of the Tourist Information Center in Berlin's Europa Center on Budapester Strasse .

In September 1992 VIDEOR D. Binninger GmbH registered the brand vidilum , under which compact fluorescent lamps were marketed.
