Noble Gases Neon Light Colors
What influences the color or heat of lightbulbs?
I know wattage makes a difference with energy, but what changes with different gases and why? (ie: Neon lighting [different noble gasses] heat from them,)
Also, any details on lesser-known differences on Compact Flourescents, Flourescents, and Incandescent bulbs?
Thank you!
Your question deals with lighting systems which are fundamentally different from one another, so let's look at each type of light bulb.
An incandescent light bulb works by passing current through a filament which acts as a resistor to the electrical current. The resistance dissipates the electrical power in the form of heat. Therefore, the filament heats up to a very high temperature (approx 3000 K). This high temperature causes the filament to radiate energy in the form of blackbody radiation. Blackbody radiation results in a broad spectrum of light that is emitted. If every color in the visible spectrum is emitted roughly equally in intensity, the light is perceived as white to our eyes. This is the reason that incandescent light bulbs have a pleasing white color, but they are very inefficient at producing light because they create a lot of useless heat.
The other types of bulbs that you are asking about (neon, compact fluorescents, and fluorescents) all create light much more efficiently than incandescent bulbs. Inside of these bulbs there is a gas (mercury gas in fluorescent bulbs and neon gas in neon lights). This gas is hit by electrons that fly through the tube. When a molecule of the gas in the tube gets hit by an electron, it absorbs the energy the electrons energy by increasing the energy level of one of the molecule's electrons. These excited electrons spontaneously become unexcited and release a photon (this is similar to the way a laser works) of a specific frequency of light which corresponds to the energy levels in the gas. This particular frequency of light looks like one particular color in the case of neon lights (red), however for mercury gas, the frequency of light emitted is not visible to the human eye. Therefore, fluorescent bulbs and compact fluorescent bulbs would produce no visible light if it weren't for the coating on the surface of the bulb. These coatings absorb the photon emitted by the mercury gas and emit photons themselves which are in the visible spectrum.
So, to answer your question, the color of light given off by an incandescent bulb depends on the temperature of the bulb. The temperature of the bulb depends on the power that is supplied to the bulb. For neon lights, the color depends solely on the gas inside the tube. For fluorescent lights the color depends on both the gas inside the tube and the coating on the surface of the bulb.

Noble Gas $151.35 High Quality Content by WIKIPEDIA articles The noble gases (often mistakenly referred to as inert gases) are a group of chemical elements with very similar properties: under standard conditions, they are all odorless, colorless, monatomic gases, with a very low chemical reactivity. The six noble gases that occur naturally are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).For the first six periods of the periodic table, the noble gases are exactly the members of group 18 of the periodic table. However, this no longer holds in the seventh period (due to relativistic effects): The next member of group 18, ununoctium, is probably not a noble gas. Instead, group 14 member ununquadium exhibits noblegaslike properties.

Neon Sign $68.51 High Quality Content by WIKIPEDIA articles Neon signs are luminoustube signs that contain neon or other inert gases at a low pressure. Applying a high voltage (usually a few thousand volts) makes the gas glow brightly. They are produced by the craft of bending glass tubing into shapes. A worker skilled in this craft is known as a glass bender, neon or tube bender. Neon sign tubes are distinguished from neon lamp bulbs by their length, customized shapes, higher operating voltages, and range of colors. The lightemitting tubes form colored lines with which a text can be written or a picture drawn, including various decorations, especially in advertising and commercial signage. By programming sequences of switching parts on and off, there are many possibilities for dynamic light patterns that form animated images.

Light Propagation in Ultracold Atomic Gases $116.3 Laser and atomic gases allow to study radiationmatter interaction at its fundamental level. After the development of laser sources, atomic gases have been successfully used to study nonlinear processes. Later on, light has been demonstrated as a very powerful tool not only to study atoms but also to manipulate them. The achievement of ultracold gases (1997 and 2001 Nobel prizes) is the most remarkable among many. Starting from an optical point of view, we theoretically investigate the features of ultracold atomic gases as an extremely dispersive and tunable medium. We first discuss the light scattering from an atomic crystal bound by light (Mott insulator) in order to gain information on the atomic structure. Then we develop a general framework for the coherent timedependent processing of a light pulse propagating in a spatially inhomogeneous system made of atomic clouds. Applications of this formalism to wavelength conversion and reshaping of the pulse are discussed. This work is directed to the AMO Physics community and it aims to point out the unique features of ultracold matter as an efficient tool to manipulate light.

Image Sensor for Detection of Gases $95.59 This work shows the results of silicon MOS device as a sensor of chemical image, for the detection and classification of hydrogen and ammonia gases, through the Scanning Light Pulse Technique (SLPT). The gate of the device was built from an AuPd bimetallic electrode, with nanometric thickness. It was proposed an X Y automatic position system for scanning the light pulsed beam, based on the PID control and on the Labview software. The data acquisition process was also automated via virtual instrumentation defined by the Labview software. The MOS device showed maximum sensitivity for hydrogen and ammonia gases when the width of the depletion layer has maximum value. The chemical images obtained from the MOS sensor response, in SLPT operation mode for hydrogen and ammonia environments, respectively, showed characteristic patterns to each kind of gas, independent of the concentration used, allowing the complete classification of these gases. The results obtained in the present work suggest the possibility of implementing an electronic nose system, using only one sensor. Author: Braga, Mauro Sergio/ J. Salcedo, W./ J. RamirezFernandez, F.

Amazing Neon Gas Art
Plasma Televisions: A Brief Overview
One of the newest crazes to hit the television industry
over the last ten years is plasma televisions. Commonly
seen in sizes thirty-seven inches and larger, this type of
television uses two noble gases - neon and xenon - that
mixes together in small cells between two plates of glass
to create plasma when electrified.
The plasma emits light and with subpixels found in the
cells the gas inhabits, pretty much every color of the
rainbow is formed and properly displayed.
Plasma technology is not as new as everyone thinks. The
first plasma display was developed in 1964 at the
University of Illinois and was used primarily for computer
screens.
The original colors that the plasma screen displayed were
monochrome, usually orange or green on a black background,
and sometimes even yellow.
These screens were very popular in the 1970's because of
their low maintenance, large screen size and relatively
small profile. IBM followed suit and produced their own
plasma screens in 1983, and in 1997, Pioneer sold the first
plasma television set.
While plasma televisions are still holding their own in the
current electronics market, they are beginning to decline
in popularity as newer LCD (liquid-crystal display) models
are advancing to the forefront.
One of the biggest drawbacks of a plasma set is the screen
burn-in. This is where one image has been displayed for a
long period of time and a "ghost" of the image has burned
into the screen. Some people claim that this never goes away, although with newer models this is probably not the case; and of course the quality of
the picture will continue to decrease over time, that is unavoidable, but will perhaps be remedied with newer models.

Im pretty sorry, in this field i only know
Niederdruck-Gasentladungslampe as a pretty long word
but thats a fluorescent tube and NOT a neon light, neon tubes are neonröhren, simple as it is.
In colloquial terms you call both neon tube, but there are no long words. If you call for long words its getting scientific
