Question 1

How do street lights work?

Accepted Answer

Typically, street lights are controlled by an astronomical clock that turns them on at night and off during the day. This control mechanism however does not dim and normally turns on between the hours of 7 p.m. and 5 a.m. In addition to clocks, photocells are used to assess ambient light levels and turn on or off a set of street lights. There are more advanced technologies, such as central management systems, via which an operator may control every streetlight. This technology could also be used to LED flood lamps to produce remote control flood lights.

Question 2

What are the components of street lights?

Accepted Answer

A streetlight is made up of various parts. The pole is constructed of wood, steel, aluminum, polyethylene (I believe), or fiberglass reinforced with polyester resin. (A business that also produces fishing rods makes some of the fiberglass ones!) The poles may be painted, powder-coated, or anodized after being treated with creosote or a copper preservative (if made of wood). The lamp housing is typically made of aluminum. Glass or polycarbonate material is used to make the lens. If it's a high-intensity discharge lamp, the ballast is comprised of steel with either aluminum or copper windings. The lamp is composed of glass (an inner capsule may be made of quartz). Metal support wires, noble gases, mercury, sodium compounds, or other metals may be found within. The capsule (or fluorescent tube) may be phosphor-coated. The lamp's base is made of aluminum or brass and is fitted into a porcelain socket with a brass, bronze, or aluminum inner shell. A circuit board constructed of fiberglass and resin with copper or gold traces is included in an LED light. A solder consisting of tin and silver is used to attach circuit components (or tin and lead). The circuit board feeds an array of light-emitting diodes connected to another circuit board, which is mounted to an aluminum heatsink or the lamp's housing with a thermally conductive paste between the board and the sink. Some LED street lighting has a fan to help cool the bulb and electronics. A photoconductor-controlled switch may be used in either light. When light reaches the photoconductor, it conducts electricity to a heating element, which heats a bimetallic strip that separates electrical connections, causing the lamp to switch off. When it becomes dark, the photoconductor stops conducting, causing the element to cool and the bimetallic strip to flex and close the contacts, therefore turning on the light. Of course, the assembly is powered by copper wires insulated by thermoplastic insulation. Steel, aluminum, or plastic conduit may be used to protect these.

Question 3

Why do we need street lights throughout the night?

Accepted Answer

It depends on whether you choose to walk or drive, and if the route is brightly lighted or dark. According to studies, most individuals will choose a well-lit route. (There are several research available online.) It is not only good for people to walk, but it is also important for drivers to identify and avoid road hazards. Pedestrians must also be aware of approaching automobiles. When there are no street lights, the light from the automobiles is reflected on a dark backdrop, causing glare ( this effect can be seen when driving at night on a dark road). Not only do street lights facilitate nightlife and promote livability, but they also improve city beauty. The street lighting system is very crucial in smart cities. A well-designed street lighting system may give the precise amount of light necessary while being environmentally friendly.
