What Are LED Seaport Lights?
Shipping ports, container terminals and ports use high-power lights in their facilities. These light fixtures consume massive amounts of electricity. But LED seaport lighting, cut power costs by up to 75%.
LED bulbs use semiconductors that turn electrons into light. LED seaport lights use it to light up ports and terminals, while reducing energy usage.
Where Is LED Seaport Lighting Used?
Port safety goes hand in hand with good lighting. As their name suggests, LED seaport lights illuminate seaports and container ports. Ports, ship yards, and container terminals need adequate lighting to ensure safety. Including navigation, safe docking, loading and unloading cargo, and moving freight around the port.
Outdoor Seaport Lighting
LED Mast Lights for Seaports and Container Ports
Where bright light is necessary, LED Mast lights are always the best choice. When placing mast lights, they illuminate a wide area with broad, powerful beams of light. This is important to seaports and container terminals to help with maneuvering and bolster security.
There are two types of outdoor flood type fixtures to choose from: area and directional. They are generally classified by the intensity and how they illuminate open areas.
Directional mast lights illuminate certain features in buildings to enhance their visual appearance. They are also used for wall washing and wall grazing. Area flood-lights, in contrast, light up large outdoor areas. This includes sports arenas, terminals, or applications that need a high luminous intensity.
Since these fixtures are outdoors, manufacturers engineer them to endure all weather conditions. The fixtures have aluminum casings. This shields the bulbs from humidity, rain, snow, storms, and temperature fluctuations.
The Main Types of Mast Lights used at Ports
Photocells are also known as dusk to dawn sensors. Some other names include CdS (Cadmium-Sulfide) cells, photoresistors, or LDR (Light Dependent Resistors). They work almost the same way as infrared sensors, which detect the presence of objects. Photo-resistors detect the presence of light. It increases or decreases resistance to regulate the amount of light.
When the surrounding environment has enough light, the resistance decreases. When it’s dark or there’s minimal light, they have a high level of resistance. The ability to regulate light is important. During the day LED flood-lights will turn off. At dusk, they turn back on.
These sensors use infrared technology to detect the movement of objects up to 8 meters away. They have a detection angle of up to 180°. They are ideal for security or perimeter lighting and in cargo bay entrances and exits.
As soon as the sensors detect movement, the lights switch on. In case there’s no movement or activity taking place, the lights switch off. The good news is existing LED highmast fixtures fit with either photocell or PIR sensors. You don’t have to buy other fixtures to use this technology.
Every seaport focuses on the following three aspects:
Port workers need proper light to cut risks and allows them to move around the yard. LED seaport lighting fixtures help using improved color rendering. Workers can see more and glare doesn't affect them.
Productivity depends on how fast containers are loaded and offloaded. This means many tasks are happening within a short time. LED light fixtures in seaports ensures quicker movement of containers in and out of the yard.
Regulatory bodies such as the EPA have stringent measures. Especially when it comes to conserving the environment. A recent study by the Royal Society showed traditional lighting is less efficient. It increases carbon dioxide emissions. They also attract some marine creatures that damage ships and boats.
Vital Considerations for LED Seaport Lighting
The IP (Ingress Protection) rating is an international rating standard. It represents the sealing effectiveness against elements such as dust, dirt, moisture, and water. Each number that follows the initials “IP” has a specific meaning. The first number is the level of protection (of the fixture) from foreign bodies. The second number is the fixture’s degree of protection against any form of moisture.
The first digit numbers are 1 to 7 while the second digit numbers are 1 to 9. If a number is x, for example IP3x instead of IP34 or IP32, it shows that the fixture is not rated for that specification.
For ports, use IP65 or greater.
This table explains IP ratings in detail:
|First Digit - Dust and Solid Objects||Second Digit - Water and Moisture|
|0||No special protection||0||No protection|
|1||Solid objects larger than 50mm – such as hands or large tools||1||Condensation or vertically falling drops of water|
|2||Solid objects larger than 12mm – like fingers||2||Vertically dropping water when the fixture is angled up to 15° from its regular position|
|3||Solid objects larger than 2.5mm – such as wires||3||Water sprays of up to 60° from the vertical|
|4||Solid objects larger than 1mm –|
Like small tools and wires
|4||Water sprays from all directions.|
|5||Dust – but not large deposits||5||Low-pressure water jets (from all directions), or water sprayed from a 6.3 mm nozzle|
|6||Completely safeguarded from dust||6||Powerful water jets, or water sprayed from a 12.5 mm nozzle|
|7||Temporary immersion (between 15cm and 1m of water)|
|8||Prolonged periods of immersion under pressure|
IK international rating is the protection against mechanical wear and tear and the extent it can withstand impact. The rating spans between IK01 and IK10.
Light fixtures with a high IK rating (between IK07 to IK10) are best for high-impact risk environments. Here they are susceptible to mechanical impacts. Low IK ratings, between IK01 and IK07, are well suited to low-impact risk areas.
Different LED products have diverse optics to offer diverse optical solutions. Non-primary optics configure the beam and radiation patterns and also maximize light efficiency. To meet lighting specifications, the non-primary optics allow for many combination possibilities.
These non-primary optics comprise of diffusers, lenses, total internal reflection lenses, and reflectors. The lenses collect light and spread the beams at a compact angle. While the reflectors redirect the beams to illuminate at a big angle. The total internal reflection lenses are responsible for gathering and processing light.
LED lights for high-voltage applications have lenses made of acrylic or polycarbonate. These lense boast superior mechanical strength and brilliant optical features. They have powerful thermal stability, excellent thermal conductivity, and water absorbing capability.
High-power flood-lights have both lenses and TIR lenses. This gives them enhanced optical efficiency and higher light uniformity. Some flood-lights have reflectors to get rid of spill light and glare. And to achieve a particular beam pattern.
Color temperature is misleading because it does not have a temperature in the true sense of the word. But color temperature is the temperature of the light color produced by a light source. Color temperature is on the light bulb (and on the packaging box) to show how bright or dim a bulb is.
For Port lighting, choose a color temperature between 4000K and 5500K.
When you want to know how an object will appear under a light source, you check its color rendering index. If the color rendering index is low (below 65), the bulb wont reveal the true colors. It won't show how the objects looks like in real life. The color rendering index measures against an ideal light source like the sun – which has a CRI of 100.
If the CRI of a light bulb is good (70-90), the colors of the objects it illuminates will appear almost real. If the CRI is excellent (90 and above), the colors appear as they would if the objects were in the sun.
Seaports need lights with a high color rendering index. This ensures easy cargo loading and offloading and safe navigation on waters. When then lights are powerful, they will maintain the recommended foot candle levels. If they are not, accidents are bound to happen.
CRI 70 or above is adequate for port lighting.
5 Reasons to Replace Traditional Seaport Lights with LED
It is no secret that LEDs have a high CRI (between 70 and 98). This means they produce more natural light than traditional light fixtures. They have the ability to show the smallest differences in color.
A high color rendering index is crucial in seaports and container terminals. It enables workers to differentiate freight by looking at their markers and colors. The ability to show differences ensures workers can spot product or equipment defects.
LED seaport lighting distributes light that can be varied and controlled to be uniform. These lights come with different beam angles for unique needs of different applications.
LED light beam angles range from 15° to 120°. A wide beam generates softer light that distributes to broad locations. While a narrow beam generates focused light. Narrow beam angles are for accent lighting.
LEDs are directional. They are not like conventional lights which emit light every direction. These lights produce focused light and their optical efficiencies range between 80%-90%. Traditional light fixtures suffer from a rapid loss of light intensity.
Take for example, metal halides. These light sources have a light intensity loss of up to 60%. Due to optical loss, light pollution (glare, spill light, uplight, and halo effect light) is a problem.
LED seaport lights use much less energy to deliver a high lumen output. For example, a 1000W HID bulb consumes up to 1150W. This is because its ballast requires approximately 15% of the energy it uses to function. So the ballast consume an extra 150 watts, translating to higher electricity costs.
So, LED fixtures consume a lot less power than traditional lighting fixtures. So a 450 watt LED bulb can replace a 1000 watt HID lamp. Moreover, LED lights do not need ballasts. What this means is that electricity consumption will decrease – by up to 75%. Pair it with controls like motion sensors and dimmers, and energy usage decreases by 90%.
See which LED seaport lights will make the best replacements for your current lights. Consider a photometric analysis for your facility.
LED lights fitted with dimmers have the ability to dim up to 100% and dimming doesn’t affect their lifespan. Their light output increases and decreases and they will experience no negative effects. This feature is useful since the lights switch off or dim when there is natural light. This saves energy in the process.
High-quality LED seaport lights keep 70% of their initial light output for up to 100,000 hours. Which is more than 5 times the lifetime of HID lamps. This means fewer light fixtures to illuminate expansive areas for a long period of time.
LEDs not only produce high-quality light, they direct it exactly where it's needed. LEDs have an advantage over omnidirectional HIDs and fluorescents which use reflectors.
For every lighting option you choose, it is important to consider the economical aspect to it. This includes electricity bills, servicing, and maintenance costs. High wattage lights use a lot of electricity to produce intense light for large areas. This is true for all traditional lighting fixtures – there are no exceptions.
Conventional lights also experience lumen loss fast with a short life span. Most of these lamps produce very bright light when they are first switched on. Lumen reduction begins within the first few hours of use. Because of this, their efficiency decreases over time with higher replacement.
Also, if the ballast in the fixture gets damaged, the bulb starts to draw electricity. This causes premature burnout and the need for a replacement.
LED lamps have a hard-wearing semiconductors and maintain 70% of their lumens for up to 100,000 hours. According to research, LED lamps only lose their initial light output by 30%. This happens at the end of their lifespan but continue to function provided there’s power.
HID lamps have a short lifespan (of up to 15,000 hours), you can make up to 6 HID replacements during the lifetime of a LED lamp. Considering seaport lights are on poles 80 to 120 ft high, bulb replacement costs can be high. And with needing special equipment.
Temperature and weather affect traditional light fixtures. Fluorescent bulbs may not work in temperatures below 50°F. But this is not because of the light, but the type of ballast used in the fixture. Magnetic ballasts do not work in cold temperatures. The output of conventional fixtures is usually poor in bad weather conditions, like when it rains.
LED seaport lights are resistant to temperature fluctuations and changes in weather. They come in different options to fit various needs. They are capable of providing bright light, especially during darker winter months. Important for enabling workers to maneuver within ports and seaports.
Outdoor LEDs have sturdy casings to protect inner components from dust, moisture, and dirt. So this minimizing the risk of fire or damage to their conductors. These lighting fixtures are verified and approved by various certification agencies.
