Gaslight technology


Control electronics

Technik von Gaslaternen: Schaltelektronik

Berlin's gas street lamps are operated easily and reliably with the aid of modern control electronics and ignition mechanisms.

Photoelectric switch

Technik der Gaslaternen: Dämmerungsschalter

The photoelectric switch automatically turns the gas lamp on at dusk and off again at dawn.

Gas vs. electricity

In contrast to electric lights (on the left), environmentally friendly gaslights (on the right) do not become contaminated with dead insects, as they do not kill them.

Overhead transmission lines

Gas is a primary energy. In contrast to electricity, gas does not have to be produced in an energy consuming process. Moreover, gas does not have to be transported to its local consumers in overhead transmission lines.

Over the past few years, more than 10,000 gas street lamps have been fitted with state-of-the-art, processor controlled electronic circuits. These circuits are solar powered. The more expensive and less environmentally friendly batteries have been discarded. A photoelectric sensor controls the light switch. Twilight and nocturnal darkness cause the lamp to switch on; daylight causes it to switch off. The sensor's sensitivity can be adjusted to each gas lamp's immediate surroundings (e.g. shadows cast by trees) with a rotary potentiometer (control knob). The gas lamp is ignited by an electromagnetic valve. A sensor monitors this process. If ignition does not occur, the valve is shut. In contrast to claims made by the Senate, gas does not continue to leak in an uncontrolled fashion.

The remaining approx. 30,000 gas street lamps still ignite with the aid of batteries. Apart from that, the ignition process is the same as described above.
