![]() The name born in the late 1800s derives from Edelgas, a German term which indicated their chemical inertness like that of nobles metals i.e. The sixth is instead a rare radioactive element. Only the first five are employed in the technology of cold cathode. This group includes in order of atomic number: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). Such gases present in a monoatomic form with a complete electronic shell. In a bit more detail, noble gases are natural elements in the atmosphere and belong to the eighteenth group of periodic table. The reason for the colour of cold cathode lamp is one among the following factors or their combination: Finally, it is important to remember that lamps with such features of color temperatures and ranges can be supplied by electromechanical transformers that operate at a low or high voltage, but also by high frequency electronic converters when the installation spaces are particularly tight. The length of the lamps may vary from 30cm to 3m, with diameters from 6mm to 25mm. ( Color Rending Index) up to 97: such index allows us to faithfully reproduce colors on a lighting element. The phosphors used belong to the "Rare Earth" class, featuring a very high chromatic yield because of their C.R.I. The color temperature available ranges from the warmest shades - 1,900 Kelvin degrees - to the absolute coolest ones - 10,000 Kelvin degrees -, with the possibility to choose from 13 different types of whites. In fact, the lighting systems designed, manufactured and marketed by the Company can meet every expectation: giving color to shape, or shape to color, depending on the requirements and perspectives of the project. Neon can satisfy every expressive need, even in terms of color.
