Street Lighting As An Important Aspect Of Security

Raised sources are the most preferred for lighting our towns, cities, road edges and walkways. In street lighting, the source of light is usually turned on and off at certain times. In modern times, lamps have photocells that are light-sensitive. Their work is to automatically turn on the light at night and off in the morning. Previously, solar dials aided this function. It is common for sources to be on tall poles connected with wires between them.

Before the invention of incandescent lamps, candles were used in cities. Later, lamps needed a lamplighter tour every night to light all the lamps. This were then improved such that, an ignition device was used. It could strike the flame on its own provided the gas supply was active.

Streets were lit electrically for the first time when arc lamps were invented. Lamps fitted with carbon arcs made sure that electrodes in the bulbs were consumed concurrently. A departmental store in France employed this technology for a very long time. However, arc lights produced hostile and intense light that caused a lot of discomfort among city dwellers. Worse still, a lot of time and money was involved in their maintenance. They got outdated as soon as affordable, reliable and more luminous incandescent lamps were invented.

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.

Light induction is an example of new technology in street illumination. It emits white light that produces better lumen. This technology, therefore, enables lights that need less electricity and lumen to be used in place of current ones. Absence of formal specifications on these lights has rendered them useless for sometime awaiting approval. There has been a substantive acceptance of LED luminaries due to the confirmation that there energy-efficiency is higher than that of previous designs.

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.
