A street light, also known as a light pole, street lamp, light standard, or lamp standard is a raised source of light on edge of a road or path, which can used to promote security in urban or city areas. Street light can use to increase the quality of life by artificially extending the hours in which it is light so that night activity can take place. The use of street lighting can be considered as a protective method which provides economic and social benefit to the public and whole the country. Street lighting is an essential public service that provides a safer environment at nighttime to the driver as well as the pedestrians on the road. While this service is commonly available in developed countries, there is a shortage of proper street lighting facilities in many areas in developing countries due to lack of financial resources. The lack of adequate light at night has given rise to poor living conditions and as such, street crimes, and other mishaps are commonplace.
Ancient people were concerned with the dangers of a dark street. Before the appear of the street light, ancient Chinese sometimes carried fireflies in transparent or semi-transparent containers and used them as (short-term and movable) street light. This kind of street light is known as the ‘lanterns’. Firefly lanterns were also being widespread to another country such as the ancient India. But these were short term solutions with a lot of weakness such as the fire in ‘lanterns’ will easily extinguish if it is being blow by strong wind. Beside that, ‘laterns’ also cause fire disaster if it does’t be use properly, and this will end up with loss of property and life. Then, in the 1930s, Low-pressure sodium-street light was introduced in Europe. After that, high-pressure sodium (HID) street light being invented in 1965, and it brought superior color and efficiency compared to their low-pressure predecessors. After 40 years, which is in 2006, the first led street light is being introduced in United Kingdom. Due to rapid grow of LED, HID streetlights may soon be just as extinct as the ‘lanterns’ in the ancient.
Today, street lighting Malaysia commonly uses high-intensity discharge lamps. Low-pressure sodium lamps became commonplace after World War II for their low power consumption and long life. Late in the 20th century HPS high pressure sodium lamps were preferred, taking further the same virtues. Such lamps provide the greatest amount of photopic illumination for the least consumption of electricity. However, white light sources have been shown to double driver peripheral vision and improve driver brake reaction time by at least 25%; to enable pedestrians to better detect pavement trip hazards and to facilitate visual appraisals of other people associated with interpersonal judgements. Studies comparing metal halide and high-pressure sodium lamps have shown that at equal photopic light levels, a street scene illuminated at night by a metal halide lighting system was reliably seen as brighter and safer than the same scene illuminated by a high pressure sodium system.
Two national standards now allow for variation in illuminance when using lamps of different spectra. In Australia, HPS lamp performance needs to be reduced by a minimum value of 75%. In the UK, illuminances are reduced with higher values S/P ratio
New street lighting technologies, such as LED or induction lights, emit a white light that provides high levels of scotopic lumens allowing street lights with lower wattages and lower photopic lumens to replace existing street lights. However, there have been no formal specifications written around Photopic/Scotopic adjustments for different types of light sources, causing many municipalities and street departments to hold back on implementation of these new technologies until the standards are updated. Eastbourne in East Sussex UK is currently undergoing a project to see 6000 of its street lights converted to LED and will be closely followed by Hastings in early 2014.
In North America, the city of Mississauga (Canada) was one of the first and biggest LED conversion projects with over 46,000 lights converted to LED technology between 2012 and 2014. It is also one of the first cities in North America to use Smart City technology to control the lights. DimOnOff, a company based in Quebec City, was chosen as a Smart City partner for this project.
Photovoltaic-powered LED luminaires are gaining wider acceptance. Preliminary field tests show that some LED luminaires are energy-efficient and perform well in testing environments.
In 2007, the Civil Twilight Collective created a variant of the conventional LED streetlight, namely the Lunar-resonant streetlight. These lights increase or decrease the intensity of the streetlight according to the lunar light. This streetlight design thus reduces energy consumption as well as light pollution.
The electrical energy consumption of street lighting constitutes an important part of total energy consumption.Saving energy in street lamps is therefore important for total energy savings. It is known that street lighting levels are excessive in many cases. For instance, in the case of low traffic volumes, the lighting levels are excessive and could be reduced so that energy savings can be achieved. On the other hand, in specific situations and for traffic safety reasons, light levels should be increased even in the case of low traffic volume. Reductions in energy consumption through the installation of modern lighting equipment, control and management practices have a direct impact on the level of greenhouse gas emissions from street lighting. Reductions in greenhouse gas emissions are directly related to reductions in energy consumption; hence the potential savings are of the same order and vice versa.
