What Are LED Container Port and Intermodal Lights?

Shipping ports and container terminals (container ports) use lighting poles with multiple high-power lights in order to illuminate their expansive facilities. These light fixtures are known to consume massive amounts of electricity, but since the advent of LED seaport lighting, power costs have been cut by up to 75%.

LED bulbs are fitted with semiconductors. They are uniquely designed to turn electrons that pass through them into light. LED seaport lights use this technology to illuminate ports and terminals, while reducing overall energy usage.

 

Where Is LED Seaport Lighting Used?

Port safety goes hand in hand with good lighting. Just as their name suggests, LED seaport lights are used to illuminate seaports and container ports. Ports, ship yards, and container terminals require adequate lighting in order to ensure safe navigation on waters, allow safe docking, loading and unloading of cargo, and movement of freight in and out of the port.

 

Outdoor Seaport Lighting

LED Mast Lights

Where bright light is needed, LED Mast lights are always the best choice. When Mast lights are strategically placed, they illuminate a wide area with broad, powerful beams of light. This is of great importance to seaports and container terminals where high intensity lighting is required to facilitate easy maneuvering and bolster security.

LED Mast lights are used outdoors. Depending on the area you want to illuminate, there are two categories of flood type fixtures to choose from: area and directional flood-lights. They are generally classified as per their intensity and how they illuminate open areas.

Directional mast lights are used to illuminate certain features in buildings in order to enhance their visual appearance. They are also used for wall washing and wall grazing. Area flood-lights, in contrast, are used to light up large outdoor areas like sports arenas, terminals, or applications that require a high luminous intensity.

Since these light fixtures are installed outdoors, manufacturers usually engineer them to endure all weather conditions. The fixtures are fitted with aluminum casings which shield the light bulbs from humidity, rain, snow, storms, and temperature fluctuations.

 

The Main Types of Mast Lights used at Ports 

Photocell Mast Lights

Photocells also go by the name dusk to dawn sensors, 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. However, photo-resistors detect the presence of light and increase or decrease resistance, therefore regulating the amount of light.

When the surrounding environment has enough light, their resistance decreases; when it’s dark or there’s minimal light, they have a high level of resistance. Their ability to regulate the amount of light is very important because during the day, LED flood-lights are automatically turned off. At dusk, they are turned back on.

Passive Infrared (PIR) Mast lights

These infrared 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 can be placed in cargo bay entrances and exits.

As soon as the sensors detect movement, the lights switch on automatically. In case there’s no movement or activity taking place, the lights switch off automatically. The good news is that most of the existing LED highmast-light fixtures can be fitted with either photocell or PIR sensors, so you don’t have to purchase other fixtures in order to benefit from this technology.

 

Vital Considerations for LED Port Lighting

The IP Rating

The IP (Ingress Protection) rating is an international rating standard that is used to represent the sealing effectiveness of light fixtures against foreign elements such as dust, dirt, moisture, and water. Each number that follows the initials “IP” has a specific meaning. The first number specifies the level of protection (of the fixture) from foreign bodies while the second number represents the fixture’s magnitude 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 replaced by x, for example, IP3x instead of IP34 or IP32, it shows that the fixture is not rated for that specification.

This table explains IP ratings in detail:

 

First Digit - Dust and Solid ObjectsSecond Digit - Water and Moisture
0No special protection0
No protection
1Solid objects larger than 50mm – such as hands or large tools1Condensation or vertically falling drops of water
2
Solid objects larger than 12mm – like fingers2Vertically dropping water when the fixture is angled up to 15° from its regular position
3Solid objects larger than 2.5mm – such as wires3Water sprays of up to 60° from the vertical
4
Solid objects larger than 1mm –
Like small tools and wires
4Water sprays from all directions.
5
Dust – but not large deposits5Low-pressure water jets (from all directions), or water sprayed from a 6.3 mm nozzle
6
Completely safeguarded from dust6Powerful water jets, or water sprayed from a 12.5 mm nozzle
7Temporary immersion (between 15cm and 1m of water)
8Prolonged periods of immersion under pressure

IK Rating

The IK rating is an international rating that signifies the level of protection a light fixture has against mechanical wear and tear and the extent to which it can withstand sudden impacts. The rating spans between IK01 and IK10.

Light fixtures with a high IK rating (between IK07 to IK10) are best suited to high-impact risk environments, where they are susceptible to mechanical impacts. Low IK ratings, between IK01 and IK07, are given to fixtures well suited to low-impact risk areas.

The European EN 62262 and the International Standard 62262 (2002) give numeric classifications to each lighting fixture that has been tested, representing the extent of impact protection. When purchasing LED Seaport lighting, it is important that you choose light fixtures with a high IK rating. This is because if the fixtures get damaged, they will still continue to function before maintenance or repairs are carried out.

The Optics

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. In order to meet lighting specifications, the non-primary optics allow for multiple combination possibilities.

These non-primary optics are comprised of diffusers, lenses, total internal reflection lenses, and reflectors. The lenses are designed to collect light and uniformly spread beams of light at a compact angle while the reflectors redirect the beams in order 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 lenses boast superior mechanical strength, brilliant optical features, powerful thermal stability, excellent thermal conductivity, and water absorbing capability.

High-power flood-lights have both lenses and TIR lenses for 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.

 

Correlated Color Temperature

Color temperature is sometimes a difficult term to define because color does not have a temperature in the true sense of the word. But color temperature is basically the temperature of the light color produced by a light source. Color temperature is usually indicated on the light bulb (and on the packaging box) to show how bright or dim a light bulb is.

Color temperature consists of a numerical value followed by the letter “K” which stands for the Kelvin scale. The scale is used in measuring color temperature because it has the ability to measure objects with very low or very high temperatures. The Celsius scale and the Fahrenheit scale are only able to measure objects with a limited temperature range. They have sensible numbers for use on earth.

Astronomers use the Kelvin scale because it can give very high numbers (like 6000°) and also very low numbers (like 0.010°). These numbers can be hard for humans to comprehend. But temperatures in space are a lot hotter and colder than earthly temperatures, hence the need for the Kelvin scale.

HIDs and fluorescents have a limited color range but LEDs have a much wider color range. In commercial and industrial spaces, the lights used typically have a color temperature between 3000K and 6000K. In spaces where very bright light is needed (like loading bays, docking yards, and ship assembly lines), the lights used must have a color temperature of 5000K-6000K.

 

Color Rendering Index

When you want to know how the colors of objects will appear under a light source, you check its color rendering index. If the color rendering index is low (below 65), the bulb will not be able to reveal the true colors – show how the objects look like in real life. This is because the color rendering index of light sources is measured against that of an ideal light source like the sun – which has an excellent CRI of 100.

If the CRI of a light bulb is good (80-90), the colors of the objects it illuminates will appear almost real. If the CRI is excellent (90 and above), the colors will appear as they would if the objects were illuminated by the sun.

Seaports need lights with a high color rendering index to ensure easy loading and offloading of cargo, easy movement of freight, and safe navigation on waters. When then lights are powerful, they will maintain the recommended foot candle levels for sufficient illumination. If they are not, accidents are bound to happen.
