Neon • Neon was discovered in 1898 by William Ramsay and Morris Travers at University College London. • Neon is a chemical element with symbol Ne and atomic number 10. • It is in group 18 (noble gases) of the periodic table. • Neon is a colorless, odorless monatomic gas under standard conditions. • About two-thirds the density of air.
Intro • They are everywhere • Not everybody knows what they are
What it started from • Heinrich Geissler (tube) • Neon Discovered in 1898 by Sir William Ramsey • Name is derived from the Greek word "neos" meaning new • Georges Claude 1910 first Neon light
First Use of Neon Sign • George Claude from France 1902 • December 11, 1910, Paris, First lamp introduced • 1915 U. S. Patent 1, 125, 476 • Neon Claude company brought neon signs to the U. S. in the 1920 s • Introduced to USA in 1923 • First couple of Neon Signs for $24, 000
Using for • • • Billboards Stores Bars Automotive accessories Las Vegas
Neon lamp is • • Glass Tube Neon gas Electricity Reaction
Way it works • • Energy reaching a certain level of ionization Positive ions Electric circuit Photon
Glass Tubes • • 4, 5 and 8 ft lengths Several composition of glass Soft Hard
Manufacturing(cont. ) • Turn on the glass welding torch and allow it to heat to at least 2200º Fahrenheit • Heat the glass and then shape it • Insert a transformer into either end • Let the tube cool • Remove the air from the tube
Manufacturing(cont. ) • Fill the tube with inert gas such as Neon • Connect the transformers on the ends of the tube • Turn the electricity on
Manufacturing Draw design of your sign on a paper Take a piece of wood 1 inch thick Trace your design onto your piece of wood Twist your neon wire into the shape of your design and lay it down onto your traced design • Glue it to the wood • •
Colors(cont. ) • A lot of different variations • Depends on inert gas
Colors(cont. ) • Red • Neon gas
Colors(cont. ) • Gold • Helium
Colors(cont. ) • Yellow • Argon
Colors(cont. ) • White or colorless • Carbon Dioxide
Manufacturing home • Neon lights can be made at home using glass tubes and an inert gas such as neon, argon or helium. • Manufacturing neon signs are largely a manual process • Bending the tube • Attaching electrodes • Fill it with gas • Close the tube from both ends with transformers • Turn it on
