Drawing of Geissler tubes illuminated by their own light, from 1868 French physics book, showing some of the many decorative shapes and colors Modern recreation of a Geissler tube in a museum A Geissler tube is a precursor to modern gas discharge tubes , demonstrating the principles of electrical glow discharge , akin to contemporary neon ...
The lamp consisted of a Geissler tube that was excited by a battery-powered Ruhmkorff induction coil; an early transformer capable of converting DC currents of low voltage into rapid high-voltage pulses. Initially the lamp generated white light by using a Geissler tube filled with carbon dioxide. However, the carbon dioxide tended to break down.
The Geissler tube was used for entertainment throughout the 1800s and evolved around 1910 into commercial neon lighting. Advances in Plucker and Geissler's discharge tube technology developed into the Crookes tube, with which the electron was discovered in 1897, and in 1906 into the amplifying vacuum tube, the basis of electronics and long ...
1904 photograph illustrating interior lighting by the first installation of Moore tubes in a hardware store in Newark, New Jersey. Moore had devised his glow discharge lighting system by 1896. [1] The Moore Lamp was an extension of the well-known Geissler tube, which used glass tubes from which the air had been removed and a different gas ...
Geissler invented the first gas-discharge lamp, the Geissler tube, consisting of a partially evacuated glass tube with a metal electrode at either end. When a high voltage was applied between the electrodes, the inside of the tube illuminated with a glow discharge. By putting different chemicals inside, the tubes could be made to produce a ...
