The invention and the inner world of the fluorescent lamp

I just got my new book "Eureka!". This is the
dramatic moments in history when a new product or process has been discovered

It 'was the book in the fluorescent lamp (or tube). This does not mean that it is not
a fascinating history - certainly is. The problem is that there is a great
"Eureka" moment. You could say that theFluorescent lamp has never been
really ever invented, but that has developed over time.

The creation of the fluorescent lamp was truly a collaborative effort that cover a
Century: Here are the steps:

1675: Jean Picard, a French astronomer, noted that the mercury in a barometer
Tube would glow when shaken. He took this observation is not included
it

1846: Julius Plucker, German mathematician and physicist, theory and
testedcolored light, by electricity produced by various
Gas. He worked with blower Heinrich Geissler invented, what with
become known as the Geissler tube in which the experiments took place outside.

1850: Heinrich Geissler tubes develop light-emitting

1857: Frenchman Alexandre Edmond Becquerel experimented with electric
exhaust pipes on the inside covered with different phosphors

1868: Becquerel published his landmarkTreaty La Lumiere, ses causes et ses effets

1893 Nikola Tesla, who is originally from Serbia, has developed fluorescent light
with high frequency lighting ballasts

1894 McFarlane Daniel Moore, inventor of the United States has created a gas discharge lamp
with carbon dioxide and nitrogen for the production of white and pink or

1901: Serial inventor Peter Cooper Hewitt of New York, invented the mercury

1926: Edmund Germer, Friedrich Meyer and Hans J. Spanner - all from Germany -
managed to produce a fluorescent tube with a gas pressure and a greater fluorescent
Inner lining that UV light is converted into white light.

1938: After the patent Edmund Germer, General Electric acquired mass

1974: GE Lighting invented light bulbs low energy compact fluorescentPear

How does it work?

First, you must have a glass tube, the small amount of a specific gas and some
Mercury sealed inside - and nothing else. The gas is argon or neon, or his
a number of other gases (each produces its own color). Electricity
from one end of the tube is passed to the next. The electrons that pass
ionize the atoms in the compound and bring it to emit ultraviolet light. L '

In contrast, a high voltage is needed to start the whole process. If the

and can automatically or can be a separate entity, usually a small plug that his

UV fluorescent tubes, which flies to tighten the trap and kill
them. Each UV lamp comes complete with a starter and choke.
