Neon Lighting
Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. Neon lights are a type of cold cathode gas-discharge light. A neon tube is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at low pressure. A high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light. The color of the light depends on the gas in the tube. Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals are used to produce other colors, such as hydrogen (red), helium (yellow), carbon dioxide (white), and mercury (blue). Neon tubes can be fabricated in curving artistic shapes, to form letters or pictures. They are mainly used to make dramatic, multicolored glowing signage for advertising, called neon signs, which were popular from the 1920s to 1960s and again in the 1980s ...

Plasma Display
A plasma display panel (PDP) is a type of flat panel display that uses small cells containing plasma: ionized gas that responds to electric fields. Plasma televisions were the first large (over 32 inches diagonal) flat panel displays to be released to the public. Until about 2007, plasma displays were commonly used in large televisions ( and larger). By 2013, they had lost nearly all market share due to competition from low-cost LCDs and more expensive but high-contrast OLED flat-panel displays. Manufacturing of plasma displays for the United States retail market ended in 2014, and manufacturing for the Chinese market ended in 2016. Plasma displays are obsolete, having been superseded in most if not all aspects by OLED displays. General characteristics Plasma displays are bright (1,000 lux or higher for the display module), have a wide color gamut, and can be produced in fairly large sizes—up to diagonally. They had a very low luminance "dark-room" black level compared ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorescent Lighting
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than an incandescent lamp. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. For comparison, the luminous efficacy of an incandescent bulb may only be 16 lumens per watt. Fluorescent lamp fixtures are more costly than incandescent lamps because, among other things, they require a ballast to regulate current through the lamp, but the initial cost is offset by a much lower running cost. Compact fluorescent lamps are now available in the same popular sizes as incandesc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thomas Alva Edison
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory. Edison was raised in the American Midwest. Early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanical laboratory in Fort Myers, Florida, in coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Palais
The Grand Palais des Champs-Élysées ( en, Great Palace of the Elysian Fields), commonly known as the Grand Palais (English: Great Palace), is a historic site, exhibition hall and museum complex located at the Champs-Élysées in the 8th arrondissement of Paris, France. Construction of the Grand Palais began in 1897 following the demolition of the Palais de l'Industrie (Palace of Industry) to prepare for the Universal Exposition of 1900. That exposition also produced the adjacent Petit Palais and Pont Alexandre III. The building was designed to be a large-scale venue for official artistic events. A pediment on the building refers to this function with an inscription that reads, "a monument dedicated by the Republic to the glory of French art." Designed according to Beaux-Arts tastes, the building features ornate stone facades, glass vaults and period innovations that included iron and light steel framing and reinforced concrete. It is listed as a historic monument (''monu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peristyle
In ancient Greek and Roman architecture, a peristyle (; from Greek ) is a continuous porch formed by a row of columns surrounding the perimeter of a building or a courtyard. Tetrastoön ( grc, τετράστῳον or τετράστοον, lit=four arcades, label=none) is a rarely used archaic term for this feature. The peristyle in a Greek temple is a peristasis (). In the Christian ecclesiastical architecture that developed from the Roman basilica, a courtyard peristyle and its garden came to be known as a cloister. Etymology The Greek word περίστυλον ''perístylon'' is composed of περί ''peri'', "around" or "surrounded", and στῦλος ''stylos'', "column" or "pillar", together meaning "surrounded by columns/pillars". It was Latinised into synonyms ''peristylum'' and ''peristylium''. In Roman architecture In rural settings, a wealthy Roman could surround a villa with terraced gardens; within the city, Romans created their gardens inside the '' domus''. The ...

Geissler Tube
A Geissler tube is an early gas discharge tube used to demonstrate the principles of electrical glow discharge, similar to modern neon lighting. The tube was invented by the German physicist and glassblower Heinrich Geissler in 1857. It consists of a sealed, partially evacuated glass cylinder of various shapes with a metal electrode at each end, containing rarefied gasses such as neon, argon, or air; mercury vapor or other conductive fluids; or ionizable minerals or metals, such as sodium. When a high voltage is applied between the electrodes, an electrical current flows through the tube. The current dissociates electrons from the gas molecules, creating ions, and when the electrons recombine with the ions, the gas emits light by fluorescence. The color of light emitted is characteristic of the material within the tube, and many different colors and lighting effects can be achieved. The first gas-discharge lamps, Geissler tubes were novelty items, made in many artistic shapes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
