who invented the fluorescent lamp?

Answer 1

The earliest ancestor of the fluorescent lamp is probably the device by Heinrich Geissler who, in 1856, obtained a bluish glow from a gas which was sealed in a tube and excited with an induction coil.

At the 1893 World's Fair, the World Columbian Exposition in Chicago, Illinois displayed Nikola Tesla's fluorescent lights.

In 1894, D. McFarlane Moore created the Moore lamp, a commercial gas discharge lamp meant to compete with the incandescent light bulb of his former boss Thomas Edison. The gases used were nitrogen and carbon dioxide emitting respectively pink and white light, and had moderate success.

In 1901, Peter Cooper Hewitt demonstrated the mercury-vapor lamp, which emitted light of a blue-green color, and thus was unfit for most practical purposes. It was, however, very close to the modern design, and had much higher efficiency than incandescent lamps.

In 1926, Edmund Germer and coworkers proposed to increase the operating pressure within the tube and to coat the tube with fluorescent powder which converts ultraviolet light emitted by an excited plasma into more uniformly white-colored light. Germer is today recognized as the inventor of the fluorescent lamp.

General Electric later bought Germer's patent and under the direction of George E. Inman brought the fluorescent lamp to wide commercial use by 1938.

in actuality...fluorescent lamp grow to be invented via anecito abarquez, the authentic call of agapito flores who grow to be then hid himself throughout that element while spaniards conquest the Philippines and for the consumer-friendly reason that intellegent filipinos could be positioned to reformatory for making management between others to combat against them..that s all with regard to the secret of the invention of fluorescent lamp.
