A street light, light pole, lamppost, street lamp, light standard, or lamp standard is a raised

source of light on the edge of a road or path. When urban electric power distribution became

ubiquitous in developed countries in the 20th century, lights for urban streets followed, or

sometimes led. Many lamps have light-sensitive photocells that activate automatically when light

is or is not needed: dusk, dawn, or the onset of dark weather. This function in older lightingsystems could have been performed with the aid of a solar dial. Many street light systems are

being connected underground instead of wiring from one utility post to another.

There are two optical phenomena that need to be recognized in street light installations.

The loss of night vision because of the accommodation reflex of drivers' eyes is the greatest

danger. As drivers emerge from an unlighted area into a pool of light from a street light

their pupils quickly constrict to adjust to the brighter light, but as they leave the pool of light the

dilation of their pupils to adjust to the dimmer light is much slower, so they are driving with

impaired vision. As a person gets older the eye's recovery speed gets slower, so driving time and

distance under impaired vision increases.

Oncoming headlights are more visible against a black background than a grey one. The contrast

creates greater awareness of the oncoming vehicle

The main stretches of highways remain unlighted to preserve the driver's night vision and

increase the visibility of oncoming headlights. If there is a sharp curve where headlights will not

illuminate the road, a light on the outside of the curve is often justified.

If it is desired to light a roadway (perhaps due to heavy and fast multi-lane traffic), to avoid thedangers of casual placement of street lights it should not be lit intermittently, as this requires

repeated eye readjustment which implies eyestrain and temporary blindness when entering and

leaving light pools. In this case the system is designed to eliminate the need for headlights. This

is usually achieved with bright lights placed on high poles at close regular intervals so that there

is consistent light along the route. The lighting goes from curb to curb

Street lighting systems require ongoing maintenance, which can be classified as either reactive

or preventative. Reactive maintenance is a direct response to a lighting failure, such as replacing

a discharge lamp after it has failed, or replacing an entire lighting unit after it has been hit by a

vehicle. Preventative maintenance is scheduled replacement of lighting components, forexample replacing all of the discharge lamps in an area of the city when they have reached 85%

of their expected life

A number of street light control systems have been developed to control and reduce energy

consumption of a town's public lighting system. These range from controlling a circuit of street

lights and/or individual lights with specific ballasts and network operating protocols. These may

include sending and receiving instructions via separate data networks, at high frequency over

the top of the low voltage supply or wireless.

Street light controllers are smarter versions of the mechanical or electronic timers previously

used for street light ON-OFF operation. They come with energy conservation options like twilight

saving, staggering or dimming. Also many street light controllers come with an astronomical

clock for a particular location or a Global Positioning System (GPS) connection to give the bestON-OFF time and energy saving.

Intelligent street light controllers also come with Global System for Mobile

Communications (GSM), Radio frequency (RF) or General Packet Radio Service(GPRS)

communication, user adjusted according to latitude and longitude(low cost type), for better streetlight management and maintenance.

Many street light controllers also come with traffic sensors to manage the lux level of

the lamp according to the traffic and to save energy by decreasing lux when there is no traffic.

America, Canada, India and many other countries have started introducing street light controllers

to their road lighting for energy conservation, street light management and maintenance,

Street light controllers can be expensive in comparison with normal timers but most of them

return the investment between 6 months and 2 years. As the equipment's lifetime is 7 to 10

years it saves energy and cost for some years.

A number of companies are now manufacturing Intelligent street lighting that adjust light output

based on usage and occupancy, i.e. automating classification of pedestrian versus cyclist,

versus automotive, sensing also velocity of movement and illuminating a certain number of

streetlights ahead and fewer behind, depending on velocity of movement. Also the lights adjust

depending on road conditions, for example, snow produces more reflectance therefore reducedlight is required.
