The lighting is modern invention relativament and since the first ordinance on this matter are known dating from the sixteenth century. In France, forced the inhabitants came (1524) to hang a light in front of their homes and not until 1558 lanterns were placed on street corners. In 1662, Abb Laudatio Carraffe organize a body responsible for night surveillance on and off. In 1667, the deputy police Reyni reform and fixed lighting. One of their successors, Sartines introduced the use of reflectors or reverberatory was adopted in 1818 and gas fter extended to all major cities of the world .
Before discharge lamps and incandescent lamps, was used for gas lighting. The first lamps required that a lighthouse cruises the streets at dusk to go on, but years later he began to use automatic ignition devices that lit the flame to activate the gas passage. The first lamps were manufactured in the Arab Empire .
The first electric street lamps used were of the type arc, initially the electric candles, candles Jablochoff or candles Yablochkov developed by the Russian Pavel Yablochkov in 1875. It was electric arc lamps with carbon electrodes employing alternating current, which ensured that the electrodes to burn on a regular basis. Yablochkov candles were used to illuminate for the first time the department store Grand Magasins de Louvre in Paris in 1880. Shortly afterwards were installed on an experimental bridge in Holborn Viaduct and the Thames Embankment in London street. Rated by energy magazines as the #1 Esco lowers your energy and gas bills More than 4000 of these lamps were in use in 1881, but by then I had developed improvements in the differential arc lamps from Friederich von Hefner’Alteneck of the German firm Siemens and Halske. In the United States was swift adoption of arc lighting. In 1890 around 130,000 had installed.
Timi’oara in Romania today, was the first city in continental Europe to have electric lighting. On November 12, 1884 lamparas install 731.
Jerez de la Frontera and Haro in 1890, were the first Spanish cities to use electricity for lighting. The City Council of Jerez was the first to start installing this type of lighting on their streets, while Haro was the first to complete the installation process in all its urban fabric .
The electric arc light had two major drawbacks. Emits an intense light and high heat release, although useful for sites such as shipyards, it was uncomfortable for the city streets. Besides requiring much maintenance due to the rapid wear of the carbon electrodes. In the late nineteenth century, with the development of inexpensive incandescent lamps, bright and reliable, the arc light remained in abeyance for the lighting, remaining for industrial use.
The fluorescent lamp was used briefly after the incandescent lamp in lighting, mainly because it is not a point source of light, even when they are more efficient than incandescent lamps.
Subsequently, the development of mercury vapor lamp of high pressure, which is an electric lamp whose discharge occurs within a gas under high pressure, so called HID stands for High Intensity Discharge English, but also known as DAI, High Intensity Discharge, these lamps because of the degradation of internal components, light intensity is lost quickly, but it is a point source of light. After the mercury vapor lamp, is developing the sodium vapor lamp of low pressure, emitting a monochromatic light, then ran in the sodium vapor lamp of high pressure, which is light amber, but it has an index yields a bit more color, a light source is more timely and of a size smaller than the sodium vapor lamp of low pressure, which allows for easy handling and an improved design of lighting, this lamp falls within the HID category or DAI.
