High-mast lighting is a tall pole with lighting attached to the top pointing towards the ground, usually but not always used to light a highway or recreational field. It is used at sites requiring lighting over a large area. The pole that the lighting is mounted on is generally at least 30 meters (100 feet) tall (under this height it is referred to as conventional lighting system), while the lighting consists of a luminaire ring surrounding the pole with one or several independent lighting fixtures mounted around it. Most units have four, six or eight lights in the ring, with ten, twelve and sixteen lights used in rarer instances. While most high-mast lights are high-pressure sodium, other types such as mercury vapor, metal halide and LED, have also been used. Some units have the lighting surrounded by a circular shield to prevent or reduce light pollution or light trespass from affecting neighbourhoods adjacent to the highway.
Maintenance of these systems are done by lowering the luminaire ring from the mast head to the base using a winch and motor to the ground or at a height accessible by a cherry picker and located in areas to allow for easier access without disrupting traffic.
High Mast Light gives the several cost effective advantages and cost is a major issue for rural area general services. This project illustrates the theoretical basis and the analytical development of the high mast lighting poles. In the late 1960‟s, studies were conducted to investigate the impact that high-mast lighting gives on traffic performance, driver visibility, and illumination costs. It was found that increasing the height of the lighting offered a noticeable advantage in that it provided drivers with increased uniformity of illumination and brightness while minimizing discomfort and disability glare. In this turn, it`s led to a reduced number of visibility related accidents. Also, lighting is a major requirement when we deal with working at the opencast mining. In opencast mining, the efficient lighting system is required while working during dark hours. In the present work, a new system of light mast tower is proposed & designed which increases the usability of the existing light mast towers. In this solution, each light mast is given a particular position to its vertical & horizontal axis which sets the light to focus in any particular area and direction to cover target area with minimum power and resource.
High-mast lighting towers are vertical, cantilevered structures that are used to illuminate a relatively large area. Although primarily used for highway intersection lighting in rural areas, they are also utilized in other large areas such as parking lots, sporting venues, or even penitentiaries. As a result, failures of these structures are critical due to the potential for them to fall across highway lanes or other. When tall masts were installed in several cities to illuminate large areas. The first known application of high-mast lighting to highways was the Heerdter Triangle installation in Dusseldorf, Germany, in the late 1950‟sItwas.followed by installations in other European countries including Holland, France, Italy, and Great Britain. With the passing of the Federal-Aid Highway Act of 1956, interest in High Mast lighting in this country was stimulated by the successful applications in Europe.Roman.
