Eastbourne in East Sussex UK is currently undergoing a project to see of its street lights converted to LED and will be closely followed by Hastings in early Milan, Italy , is the first major city to have entirely switched to LED lighting.

It is also one of the first cities in North America to use Smart City technology to control the lights.

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.

This streetlight design thus reduces energy consumption as well as light pollution. Two very similar measurement systems were created to bridge the scotopic and photopic luminous efficiency functions, [45] [46] [47] creating a Unified System of Photometry.

The cost-savings potential of using a new way to measure mesopic lighting scenarios is tremendous. Outdoor Site-Lighting Performance OSP is a method for predicting and measuring three different aspects of light pollution: glow, trespass and glare.

Major advantages of street lighting include prevention of accidents and increase in safety. Furthermore, in the s, lighted intersections and highway interchanges tend to have fewer crashes than unlighted intersections and interchanges.

Towns, cities, and villages use the unique locations provided by lampposts to hang decorative or commemorative banners.

Many communities in the US use lampposts as a tool for fund raising via lamppost banner sponsorship programs first designed by a US based lamppost banner manufacturer.

The major criticisms of street lighting are that it can actually cause accidents if misused, and cause light pollution. There are also physical dangers to the posts of street lamps other than children climbing them for recreational purposes.

Street light stanchions lampposts pose a collision risk to motorists and pedestrians, particularly those affected by poor eyesight or under the influence of alcohol.

This can be reduced by designing them to break away when hit known as frangible , collapsible, or passively safe supports , protecting them by guardrails, or marking the lower portions to increase their visibility.

High winds or accumulated metal fatigue also occasionally topple street lights. In urban areas, light pollution can hide the stars and interfere with astronomy and the migration of many bird species.

These lamps are advantageous over other lamps such as mercury and metal halide lamps because low pressure sodium lamps emit lower intensity, monochromatic light.

Observatories can filter the sodium wavelength out of their observations and virtually eliminate the interference from nearby urban lighting.

Full cutoff streetlights also reduce light pollution by reducing the amount of light that is directed at the sky which also improves the luminous efficiency of the light.

In the Netherlands , Philips found that birds can get disoriented by the red wavelengths in street lighting, and in response developed alternative lighting that only emit in the green and blue wavelengths of the visible spectrum.

The lamps were installed on Ameland in a small scale test. If successful, the technology could be used on ships and offshore installations to avoid luring birds towards the open sea at night.

This is typically midnight to AM, as seen by the sign on the right. There have, however, been questions about the impact on crime rates.

A number of street light control systems have been developed to control and reduce energy consumption of a town's public lighting system. 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. 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.

The United States, Canada, India, and many other countries have started introducing street light controllers to their road lighting for energy conservation, street light management and maintenance purpose.

As the equipment's lifetime is 7 to 10 years, it saves energy and cost after the initial investment has been recouped. A number of companies are now manufacturing intelligent street lighting that adjust light output based on usage and occupancy, i.

Also the lights adjust depending on road conditions, for example, snow produces more reflectance therefore reduced light is required.

There are three distinct main uses of street lights, each requiring different types of lights and placement.

Using the wrong types of lights can make the situation worse by compromising visibility or safety. A modest steady light at the intersection of two roads is an aid to navigation because it helps a driver see the location of a side road as they come closer to it, so that they can adjust their braking and know exactly where to turn if they intend to leave the main road or see vehicles or pedestrians.

A beacon light's function is to say "here I am" and even a dim light provides enough contrast against the dark night to serve the purpose.

To prevent the dangers caused by a car driving through a pool of light, a beacon light must never shine onto the main road, and not brightly onto the side road.

In residential areas, this is usually the only appropriate lighting, and it has the bonus side effect of providing spill lighting onto any sidewalk there for the benefit of pedestrians.

On Interstate highways this purpose is commonly served by placing reflectors at the sides of the road. Because of the dangers discussed above, roadway lights are properly used sparingly and only when a particular situation justifies increasing the risk.

This usually involves an intersection with several turning movements and much signage, situations where drivers must take in much information quickly that is not in the headlights' beam.

In these situations a freeway junction or exit ramp , the intersection may be lit so that drivers can quickly see all hazards, and a well-designed plan will have gradually increasing lighting for approximately a quarter of a minute before the intersection and gradually decreasing lighting after it.

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 the dangers of casual placement of street lights, it should not be lit intermittently since this requires repeated eye readjustment, which causes 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. Further information: pedestrian crossing Lighting. Policies that encourage utility cycling have been proposed and implemented, including lighting bike paths to increase safety at night.

Lights similar to street lights are used on railway platforms at train stations in the open air. Their purpose is similar to that of beacon lights: they help a train driver see the location of a station at night as the train comes closer to it, so that the driver can adjust the braking and know exactly where to stop.

A train station light must never shine directly onto the tracks, and has the bonus side effect of providing spill lighting onto any platform for the benefit of passengers waiting there.

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.

In the United Kingdom the Roads Liaison Group has issued a Code of Practice recommending specific reactive and preventative maintenance procedures.

Some street lights in New York City have an orange or red light on top of the luminaire light fixture or a red light attached to the lamppost.

This indicates that near to this lighting pole or in the same intersection, there is a fire alarm pull box. Street light from the s attached to a utility pole in New Jersey.

Let us do a free photometric with one of our many cobra head options. This means you can turn off or dim each fixture in the absence of motion.

This does not affect the life of the LEDs, other than it will extend it. And a dimmed light uses less electricity, saving you even more on your lighting bill.

Think about this. That's a reduction of Watts. That's huge! Other color temperatures available upon request.

Both offer a significant improvement over high pressure sodium lights, rated at K. The amount of blue light they emit is small.

This is a measurement of the quality of light that the fixture is producing. It is a scale between 0 and Sunlight is A general rule is that you need less quantity of light if you have better quality.

L70 Light Maintenance , hours Lumen maintenance relates to the lifespan of a light source. LED lights do not burn out like traditional lights.

They maintain initial lumens longer. What happens is the light intensity fades gradually, but this usually takes years.

Used 12 hours a night, our LED Shoebox fixtures will provide bright, maintenance free lighting for years. It indicates the lumens produced for every watt of electricity consumed.

LEDs are more efficient than traditional bulbs with a higher luminous efficacy. High quality LEDs have awesome efficacy ratings.

The standard luminous efficacy is upwards of lumens per watt. To calculate luminous efficacy, divide the number of lumens the lamp generates by the watts of electricity it consumes.

Reduced Light Pollution Traditional street lights may illuminate streets and sidewalks at night, however, they are notorious for light pollution.

Light pollution is misdirected and excessive outdoor lighting. As countries and cities become more developed, the constant demand for street lighting increases the threat of light pollution.

Light pollution occurs in different ways including light trespass light spill , sky glow, glare, and light clutter.

It affects the environment as carbon dioxide is released into the atmosphere. The International Dark-Sky Association states that each year, about 12 million tons of carbon dioxide are released by invasive night time lighting.

Light pollution also affects the lifestyle of mammals, birds, amphibians, and insects by causing disorientation and affecting their migration, sleeping, mating, and feeding cycles.

LED technology has addressed the light pollution problem by developing light fixtures that focus light only where it is required.

The Problem with Conventional Street Lighting Street lighting is as important today as it was several years ago.

Traditional street lighting systems have been useful over time. But, they have caused the following problems for cities, municipalities, and residents: High Energy Consumption First of all, the energy consumption of traditional street lights is high.

During cold weather, traditional lamps need more energy to produce light. Over lighting is another problem. Traditional HID bulbs cannot dim and thus provide unnecessary bright light.

In some cities, even with low amounts of pedestrians and cars, street lights operate at high intensity. This leads to wasted energy and environmental issues.

LEDs can be controlled and dimmed to provide lighting when required. Light trespass occurs when street lights produce unwanted light.

They shine onto adjacent residential properties. Another problem with street lighting is the maintenance of traditional lighting systems.

Due to their short lifespan, they need relamping and servicing quite often. Money spent on purchasing new lamps, fixtures, and on labor could be spent on better programs.

A LED light could operate for 10 years without the need for maintenance. High pressure sodium produce yellow light and have poor color rendering ability.

Old fashioned street lighting on some streets distributes uneven. Lamp posts are far apart from each other, creating wide dark patches.

In these situations a freeway junction or exit rampthe intersection may be lit so that drivers can quickly see all hazards, and a well-designed plan will have gradually increasing lighting for approximately a quarter of a minute before the Courtney Thorne-Smith and gradually decreasing Christina Kaufmann after it.

Less than two years later, on 31 Decemberthe Westminster Bridge was lit by gas. LEDs can be controlled and dimmed to provide lighting when required. Traditional street lighting systems have been useful over time.
