Neon sign in the context of "Electronic sign"

A variable- (also changeable-, electronic-, or dynamic-) message sign or message board, often abbreviated VMS, VMB, CMS, or DMS, and in the UK known as a matrix sign,is an electronic traffic sign often used on roadways to give travelers information about special events. Such signs warn of traffic congestion, accidents, incidents such as terrorist attacks, Amber/Silver/Blue Alerts, roadwork zones, or speed limits on a specific highway segment. In urban areas, VMS are used within parking guidance and information systems to guide drivers to available car parking spaces. They may also ask vehicles to take alternative routes, limit travel speed, warn of duration and location of the incidents, inform of the traffic conditions, or display general public safety messages.

The culture of Shanghai or Shanghainese culture is based on the Wuyue culture from the nearby Jiangsu and Zhejiang province, with a unique "East Meets West" Haipai culture generated through the influx of Western influences since the mid-19th century. Mass migration from all across China and the rest of the world has made Shanghai a melting pot of different cultures. It was in Shanghai, for example, that the first motor car was driven and (technically) the first train tracks and modern sewers were laid. It was also the intellectual battleground between socialist writers who concentrated on critical realism, which was pioneered by Lu Xun, Mao Dun, Nien Cheng and the famous French novel by André Malraux, Man's Fate, and the more "bourgeois", more romantic and aesthetically inclined writers, such as Shi Zhecun, Shao Xunmei, Ye Lingfeng and Eileen Chang.

In past years, Shanghai has been recognized as a new influence and inspiration for cyberpunk culture. Futuristic buildings such as the Oriental Pearl Tower and the neon-illuminated Yan'an Elevated Road are examples that have boosted Shanghai's cyberpunk image. The city is well known for having a vibrant international flair.

A neon lamp (also neon glow lamp) is a miniature gas-discharge lamp. The lamp typically consists of a small glass capsule that contains a mixture of neon and other gases at a low pressure and two electrodes (an anode and a cathode). When sufficient voltage is applied and sufficient current is supplied between the electrodes, the lamp produces an orange glow discharge. The glowing portion in the lamp is a thin region near the cathode; the larger and much longer neon signs are also glow discharges, but they use the positive column which is not present in the ordinary neon lamp. Neon glow lamps were widely used as indicator lamps in the displays of electronic instruments and appliances. They are still sometimes used for their electrical simplicity in high-voltage circuits.

Tanning lamps (sometimes called tanning bulbs in the United States or tanning tubes in Europe) are the part of a tanning bed, booth or other tanning device which produces ultraviolet light used for indoor tanning. There are hundreds of different kinds of tanning lamps most of which can be classified in two basic groups: low pressure and high pressure. Within the industry, it is common to call high-pressure units "bulbs" and low-pressure units "lamps", although there are many exceptions and not everyone follows this example. This is likely due to the size of the unit, rather than the type. Both types require an oxygen free environment inside the lamp.

Fluorescent tanning lamps require an electrical ballast to limit the amount of current going through the lamp. While the resistance of an incandescent lamp filament inherently limits the current inside the lamp, tanning lamps do not and instead have negative resistance. They are plasma devices, like a neon sign, and will pass as much current as the external circuit will provide, even to the point of self-destruction. Thus a ballast is needed to regulate the current through them.

The Odeon Luxe Leicester Square is a prominent cinema building in the West End of London. Built in the Art Deco style and completed in 1937, the building has been continually altered in response to developments in cinema technology, and was the first Dolby Cinema in the United Kingdom.

The cinema occupies the centre of the eastern side of Leicester Square in London, featuring a black polished granite facade and 120 feet (37 m) high tower displaying its name. Blue neon outlines the exterior of the building at night. It was built to be the flagship of Oscar Deutsch's Odeon Cinemas chain and still holds that position today. It hosts numerous European and world film premieres, including the annual Royal Film Performance.

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 called phosphors are used to produce other colors, such as hydrogen (purple-red), helium (yellow or pink), 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.

The term can also refer to the miniature neon glow lamp, developed in 1917, about seven years after neon tube lighting. While neon tube lights are typically meters long, the neon lamps can be less than one centimeter in length and glow much more dimly than the tube lights. They are still in use as small indicator lights. Through the 1970s, neon glow lamps were widely used for numerical displays in electronics, for small decorative lamps, and as signal processing devices in circuitry. While these lamps are now antiques, the technology of the neon glow lamp developed into contemporary plasma displays and televisions.
