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.
Arc lamps were later developed as the first ever form of lighting the streets electrically. A carbon arc lamp using alternating current ensured that the two electrodes were used at the same rate. This type of lighting was used for lighting a departmental store in Paris. The problem with arc lights was that it emitted intense and harsh light which was a source of discomfort in the streets. Worse still, maintaining them required a lot of time and resources. They became obsolete when cheap, bright and reliable incandescent bulbs came into use.
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.
Currently, high intensity discharge lamps are used in lighting the streets. They are in most cases high pressure sodium lamps. They give out very large amounts of illumination while using little amounts of power. They are, however, inappropriate for lighting at night compared to white light. White light has been proven to help drivers see better at night, and react to brake faster than pressured sodium lamps.
White light emitted by induction lights gives better lumen than those produced by previous sources. New technology has, therefore, brought less power consuming lights to replace existing forms of light. The newly invented lights have, however, lacked official specifications making them wait for a while longer before being accepted by most municipalities. Most towns are of lit using LED luminaries because they are efficient in energy production and consumption, and they perform well.
A harmonious system of photometry was created by coming up with two similar measurement systems. This was a good idea since less power is used compared to previous methods. It saves the cost involved in measurement. The new method; Outdoor Site-Lighting Performance predicts and measures three elements of light pollution: trespass, glow and glare. This method makes it possible for lighting technicians to quantify the working of current and planned illuminating designs and applications to cut down excessive illumination crossing the boundaries of a 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.
