At present, there are different types of street lights manufactured by various companies which are made to fulfill several applications. In order to illuminate numerous outdoor areas, there are street lights specially made for roads, gardens, highways, parking lots, and more. 

It can get confusing to choose the ideal type of light for market needs if one is not aware of the various types of street lights. People may wonder about what type of lights are street lights, what type of bulbs are used in street lights, and what are their pros, cons, and applications. This guide can help everyone to get a grip on the various street light types accessible in the present market. 

What Are Street Lights 

Roadways, parking lots, walkways, and other public spaces are illuminated by street lights, commonly referred to as street lamps. By enhancing lighting brightness in dark spaces, they increase security and driving safety. They are frequently utilized in conjunction with various traffic safety tools to improve the visibility of tools, barriers, or dimly lit public spaces.

The main purpose of street lights is to provide illumination to locations or objects that are dark and difficult to see at night. In order to get the right light, color, and temperature of light for particular applications, street lights use the technologies of light-emitting diode (LED), high-pressure sodium, low-pressure sodium, incandescent, metal halide, mercury vapor, and high-intensity discharge bulbs. 

The most recent technology in street lights is LEDs. They provide the best light for the least amount of energy used, require little maintenance, and have a longer lifespan. In order to resist corrosion and other external conditions, street lights are frequently composed of a durable plastic substance like high-density polyethylene or a corrosion-resistant metal like aluminum. Street lights are designed to be put on poles, specifically designated poles or pre-existing utility poles. 

Features And Specifications Of Street Lights

Here are the typical features and specifications of street lights. 

Power 

The street lights are accessible in various power ranges, such as 100W, 150W, 200W, 400W, and so on. The power consumption of the light is a vital factor to curtail total energy expenses. 

Operating Temperature 

Operating temperature is a specific temperature range the light is constructed to operate. The outdoor street lights have a good enough operating temperature to resist various weather elements. 

Brightness 

The brightness produced by a street light varies from one model to another. Though all of the decent street lights produce bright light, some high-end street lamps generate super bright lighting to illuminate a large area. 

Supply Voltage 

The supply voltage is the voltage provided to the light itself to deliver the power. It is crucial to select a voltage that shows compatibility with the already existing infrastructure. 

Photo Sensor Activated 

Almost all street lights come with a built-in photo sensor to ensure that the light is on only when the surroundings are dark. 

Integrated Solar Panel 

The solar street lights are equipped with a solar panel as the primary power source or backup to lessen operational expenses.  

History Of Street Lights

Ancient lamps were utilized by the Greek and Roman cultures. The lights were largely used for security: to prevent roamers from stumbling over obstacles and to deter burglars from committing crimes.

The first public street lighting was created in the 16th century. It quickly spread after the development of lanterns with glass panes, which significantly increased the amount of light.

The reverbere, which is an enhanced oil lantern, was presented in 1745 and refined in the following years. A few individuals complained about glare due to the stronger light coming from these reverberes.

The initial widely used street lighting system ran on piped coal gas. In 1726, Stephen Hales was the initial individual to obtain a combustible fluid from the substantial distillation of coal. 

In 1857, 1000 kerosene-fueled modern street lighting was first put into use in Bucharest, Romania.  

The first arc lamps used in electric street lighting were known as “Electric candles,” “Yablochkov candles,” or “Jablotchkoff candles.” Pavel Yablochkov created these lights in 1875.

In 1879, Chesterfield Street in Virginia became the first-ever road to have an incandescent light bulb installed on it. 

Following World War II, low-pressure sodium (LPS) lamps gained popularity due to their extended lifespan and low power consumption. High-pressure sodium (HPS) lamps were the dominant option in the late 20th century.

The latest street lights are LED street lights. The LED street lights can be used to replace existing street lights since they use less energy and produce fewer photopic lumens. In addition, they deliver a white light with a high scotopic lumen output.

Incandescent Street Lights 

Since Thomas Edison created incandescent light more than a century ago, it has largely had a similar design. It generates light by running electricity via a tungsten filament until it shines. They are relatively ineffective and extremely hot to touch as they discharge plenty of heat.

While it is not recommended to utilize them, a few villages continue to do so because they have a sentimental appeal to a bygone era. The common applications of incandescent lights include headlights, sports field lights, floodlights, and stadium lights. 

The tungsten-halogen filament is used in incandescent street lights. They outperform other types of lights in terms of brightness, efficiency, and color rendition. However, the primary drawback of these lights is that they have a shorter lifespan. 

Advantages:

• Accessible at an affordable price 
• Low cost of production 
• The color rendition is excellent (a 2700K color temperature yields a CRI of 100). 
• It can operate with both DC and AC power and is very adaptable to wide voltage and current ranges.

Disadvantages: 

• Only 10 lumens efficiency rate 
• The light has a very short working duration 
• The maintenance costs are very high 
• The energy is wasted in generating the heat 

Fluorescent Street Lights 

The fluorescent lights emit light by passing electricity via a gas, which results in the phosphor coating within the tube to shine. Although they cost more to install, these lights are far more efficient than incandescent lights. Since they are less frequently utilized in residences, they can be found in factories, office buildings, warehouses, and retail establishments.

The latest fluorescent lights that have more recent designs are more effective. Fluorescent street lights first gained popularity in the 1940s. A vintage fluorescent light can be identified by its tubular shape. 

On both ends of this kind of street light, there is a metal electrode. It has mercury and argon gas within the tube, which assist light the lamp. Fluorescent street lights essentially provide intense UV photons but little visible light. These lights are used for street lighting in parking lots. Their life expectancy is between 7,500 and 20,000 hours. 

Advantages:

• These lights produce less heat than incandescent lighting.
• More effective than outdoor incandescent street lights.

Disadvantages:

• Takes a long time for the heat to build up for the light to become totally bright
• You cannot use a dimmer switch with it.
• Risky due to the presence of mercury
• These lights are sensitive to cold and windy settings

Mercury Vapor Street Lights 

Bright, durable lights like mercury vapor lights are frequently utilized to illuminate big spaces like streets, sports stadiums, gyms, buildings, malls, and so on. The mercury vapor discharge is included inside a quartz tube within the lights. A protective outer glass that blocks dangerous short-wavelength ultraviolet (UV) light surrounds it. 

People appear to disapprove of the old models of the mercury vapor light since they are immediately identifiable by their bluish-green glow. As phosphor was added to more recent models to enhance their designs and provide more white light, they were referred to as “color corrected” lights. 

Mercury vapor lamps offer effective, long-lasting sources of light when used normally. Intense UV radiation is released if the outer light breaks and the inner tube generates light without protection. This level of UV exposure can result in double or blurred vision, eye and skin burns, headaches, and dizziness.

Due to the fact that these signs may not become apparent for a few hours, it can be challenging to determine if you have been disclosed to dangerous levels of UV radiation.

Advantages:

• These lights are highly efficient than incandescent lights and fluorescent lights.

Disadvantages:

• It dims more promptly than other types of lights.
• Dangerous emissions because it emits UV rays.

High-pressure Sodium(HPS) Street Lights 

The high-pressure sodium (HPS) lights come under the high-intensity light bulbs that produce a lot of light and are typically used for security and street lighting. An orange-white light, which is frequently seen in street lights, is produced by the interaction of metals and gases inside the glass tube.

When HPS lights are first turned on, they actually emit a pink twinkle that later turns into a bright pinkish-orange light. HPS lights are preferred by indoor gardening due to the broad color-temperature spectrum they provide and the relatively low operating costs.

When tested for photopic lighting circumstances, high-pressure sodium lights have an efficiency of roughly 100 lumens per watt. The most powerful 600 Watt versions even possess an efficiency of 150 lumens per watt. Since these lights are dimmer in color, the maximum of their high output is invisible to the human eye. 

Advantages: 

• Greater longevity (24,000 hours) 
• Available at an affordable price range 
• These lights are highly productive than incandescent lights and mercury vapor lights.
• Maintains fast warm-up time compared to other lamp types.

Disadvantages: 

• It can take some time for the light to turn on.
• When it reaches the end of its lifespan, it emits a crimson tint and burns. 
• It requires a ballast or transformer for current restriction and to alter the voltage.

Compact Fluorescent Light (CFL) Street Lights 

These CFL street lights are nearly spiral fluorescent lights that have been scaled down to be more portable. They operate substantially cooler than conventional incandescent lights and are more productive than their equivalents. Although linear fluorescents were developed in the 1900s, it was not until the 1960s that CFL technology advanced. 

The actual fluorescent light might easily be shrunk. However, the true difficulty was in designing a small and more portable ballast, particularly when it came to fusing it with the light itself. There are two different types of CFLs: non-integrated ballast CFL and integrated or self-ballasted CFL. 

The type of CFL technology that we generally refer to as a “plug-in” is a non-integrated ballast. It implies that the ballast will be purchased separately from the light and set up in the accessory. Though it is identical to linear fluorescents, it is relatively small compared to a linear ballast. CFL street lights with integrated ballasts were developed to take the place of halogen and incandescent lighting. 

Advantages: 

• Works for a longer duration and is more productive than fluorescent lighting.
• Compact design 
• Compared to fluorescent light, it has a more regulated beam spread.

Disadvantages: 

• Ballast is necessary for CFL.
• At the halfway point of its lifespan, illumination intensity may decrease. 

Solar Street Lights 

Photovoltaic technology is used in solar street lighting systems to renovate sunlight into DC power via solar cells. The electricity produced can be utilized right away during the day or it can be stocked in batteries to be used during the nighttime. 

The battery box, solar photovoltaic module, lamp post, and lamp with charge controller make up the solar street lighting system. For illuminating streets in isolated settlements, solar street lighting systems are suitable. These lights come with enough battery backup to produce light for ten to eleven hours every day.

The system is equipped with an overcharge or deep discharge protection cut-off with LED indicators and an automatic ON and OFF time switch. The SPV modules possess a lifespan of 15 to 20 years. The solar street lighting system includes tubular batteries, which need less maintenance, carry a longer lifespan, and operate better.

Advantages: 

• There is no need for electricity.
• These lights are simple to install and easy to use
• They are eco-friendly 
• Requires little to no maintenance  

Disadvantages:

• More expensive initial investment than traditional street lighting 
• Can be stolen due to non-wiring 
• Dust, snow, and moisture can build on horizontal PV panels. 
• Over the course of the light’s lifetime, rechargeable batteries will need to be changed from time to time. 

LED Street Lights – The Best Street Lighting Solution 

The lighting elements that have LED light sources and use LED street light technology are utilized to brighten streets and roads. These lights are known as LED street lights and a few manufacturers describe them as LED road lighting fixtures. 

Compared to earlier lighting systems, LED street lights can save between 30% and 70% of energy. Even with no maintenance, LED street lights last for decades. The 2014 Nobel Prize in Physics was awarded for the invention of LEDs (light-emitting diodes), which make use of a novel sort of technology. 

LED street lights are 90% more efficient at producing light. In general, LEDs do not “burn out” or stop working. It is because they suffer from “lumen depreciation,” in which the LED’s brightness gradually decreases over time.

How Does A LED Street Light Work 

Visible light is produced when an electrical current flows through a microchip and ignites the tiny light sources known as LEDs. The heat that LEDs generate is consumed into a heat sink in order to deter performance difficulties.

Several LED street lights include a lens on the LED panel that is made to cast its light in a rectangular structure. In this instance, a significant portion of the light’s brightness is lost, resulting in the light pollution of the surrounding area and the air. A permanent light source may be integrated into a few LED light fixtures.

Advantages Of LED Street Lights 

Here are some of the pros of installing LED street lights. 

Energy efficient 

Due to their low heat output, LEDs are far more energy-efficient than their conventional counterparts. In addition, they need very little electricity to provide the exact quantity of light. The energy efficiency of LED lighting is between 40 and 60 percent higher than that of conventional lighting. 

Fewer emissions 

LED street lights use less energy and produce fewer pollutants than their conventional counterparts. As per the reports, switching to LED outdoor lighting can lessen carbon emissions greatly. 

Longer lifespan 

The extended lifespan of LED lighting products, which outlives conventional illumination, is another advantage of LED street lights. For instance, LED lights can last 30 times more than incandescent lights and three to five times more than fluorescent lights.

Looking for the Perfect Street Light? Ask Yourself These 4 Questions

Unlike some years ago, LED technology is now a clear choice for anyone purchasing street lights to public areas. Finding a perfect street light, however, is far from the obvious.

Here’s the challenge.

Before the age of LED, the contractors and designers had some 3 to 5 alternative street luminaires to choose from. Today, there are millions of options and the number keeps on growing as technology and suppliers evolve.

At the same time, most of the exterior lighting is on public areas and in many cases, at the very heart of the debate concerning safety, sustainability and environmental issues.

For anyone purchasing LED street lights, the goal is to find an energy-saving, sustainable solution that creates safety and appeal. But how to find the right solution among all of those alternatives?

While every project is different, there are certain things in common. Here are 4 questions you should be asking yourself if you’re searching for that perfect street light.

How do I determine the right light level of the street?

Exterior lighting is needed for a number of different causes, including facades, lanes, parks, cycleways and motorways. Depending on the area, lighting can support orientation, highlight activities, improve safety, express character or stage events, for example.

In street lighting, the determining factors you should consider are the amount of traffic and the type of traffic. These two factors determine whether street lighting is needed and if so, what kind.

In public areas, the amount and type of traffic further determine which lighting class a certain street falls into. The municipalities and cities decide these lighting classes themselves, basing their decision on street lighting design guidelines.

In the Nordics, there are shared design guidelines that each country applies and specifies. The higher the lighting class, the more requirements for the lighting. In practice, the lighting class (ranging from 1 to 6) determines how much light is needed and how even the light should be. At busy city centers, the lighting class might be as high as 1 or 2 and on silent streets 5 or 6.

Should the luminaires be CUSTOMISED?

Even after determining a lighting class, each street has its unique characteristics. There are big differences in the width of the road, pole distance and pole height, to name a few. Because of the differences, the luminaires need customisation to assure high-quality lighting on every street. Usually, the customisation has to do with the luminaire’s light output, optics or both.

Often, it’s about finding the right balance in customisation. In the end, it’s all about listening to the customer’s needs and finding that right balance with different factors.

Which features should I draw attention to?

With exterior lighting, the durability of the luminaires is vital. Outdoors, the luminaires are always exposed to tough conditions, including heat, cold and moist. As opposed to nature’s own twists, vandalism is always another concern on public spaces.

The single most important thing affecting the lifespan of LED luminaires is heat control. In other words, the lifespan of the luminaires is a lot longer if the LEDs, along with the drivers, are kept cool. Therefore, make sure the thermal management of the luminaires is well designed and never compromise vital attributes over price.

Apart from thermal management, make sure the street light you choose has:

• Recyclable, tested materials
• Wide enough power range
• Wide optics spectrum
• Replaceable components
• High IP & IK class
• Long guarantee
• Smart City compatibility

What can I do to prepare for the future?

Everywhere in the world, cities are evolving rapidly and the concept of Smart City is more and more talked about. For anyone dealing with public lighting, the compatibility and interoperability of lighting and different smart city applications have become areas of interest.

While the harmonisation and standardisation are yet to be established in the lighting world, as a purchaser of LED street lights make sure the luminaires you choose may be easily adapted for future needs.

Do the luminaires support different kinds of connectors? Is the supplier up-to-date with the latest development? In a rapidly changing scene, you need a companion that has the latest information and the ability to integrate and react to future needs.
