It is common for streets to have tall posts on which bulbs are mounted to facilitate vision over a wide field of view. Methods are always put in place to control the bulbs in street lighting. Photocells that sense light are in modern days the main components of lamps. They are charged with the responsibility of putting on the lights when needed and off when not needed. In the past, solar dials assisted in doing this job. The poles on which the sources are mounted are always interconnected using cables.
Prior to the discovery of incandescent lamps, candle light lit the streets. A slight improvement on this introduced lamp lighting trips in the city each morning. These trips were always aimed at lighting all lamps in the streets. Later, ignition equipments were used to do this. The devices could strike flames automatically for as long as there was gas supply.
Invention of arc lamps made its mark as the foremost electric street illuminating method. Lamps made of carbon arcs using alternating current were used for ensuring that consumption of both electrodes took place at an equal rate. A departmental store in the French capital used this lighting system. The disadvantage with this type of illumination was the harsh intense light it emitted. It caused a lot of discomfort in towns, and maintaining it was time and resource consuming. They were replaced by brighter, cheaper and more reliable incandescent bulbs.
A very high voltage is always used in operating incandescent bulbs whose circuits were arranged in series. The fact that high voltages in circuits emitted more photons of light for each watt made series circuits very common. The whole district could also be easily controlled using series arrangements.
In modern times, lighting the streets applies very intensive discharge lamps. Mostly, high pressure sodium bulbs are used. These bulbs use a very little amount of electricity, but emit a lot of light. However, if light calculations are done, these lamps are often discovered as being inappropriate for night illumination as contrasted to white illuminations. Research has found out that whit light is good for peripheral vision of drivers and their reaction to brake.
New technologies for street illumination like induction lights produce white light that gives high levels of lumen. This makes it possible for illumination that requires less power and lumen to substitute current ones. Lack of official specifications on the prescribed lights has made it impossible for most municipalities to endorse them. LED luminaries are being widely accepted owing to test confirmations that they are more energy-efficient and perform well.
A new harmonized measurement system has been invented. It operates using two concurrent measuring systems. This was seen as being a noble invention since less energy is spent compared to earlier methods. The cost of measurement is greatly reduced. It is possible to measure three light pollution properties; glare, trespass and glow, using this method. It is also practical to assign a value to the performance of current and future lighting applications and designs for the sake of cutting down the amount of light crossing the borders of any property.
Lighting on Streets is very vital because it keeps at bay the likelihood of accidents, and, at the same time, improves safety by aiding vision. If misused, however, it can cause accidents such as loss of vision, electrocution, and head-on collisions.
