UV LED Lamp Applications in Commercial Aquariums

In marine locations, ultraviolet UV LED lamp is mostly used for non-invasive disinfection. Specifically, UVC, with a wavelength range of 200-280 nm, is applicable to large-scale sterilization, which can be found in industrial water treatment plants and food processing facilities.

Commercial aquariums also use UVC LED lamps to streamline cleaning inside tanks that hold corals and fish. This article expounds on such applications and provides tips for proper usage.

UV LED Sterilizers

UV LED luminaries inside aquariums are utilized to disinfect the water and surface. The lamps target bacteria, algae and harmful parasites that could cause diseases inside domesticated fish.

There are two types of UV sterilizers for tanks and large chambers: inline and hanging. The main difference between the two options is their mounting mechanisms. An inline UV LED unit is designed to work with the core filtration component of the aquarium. It is installed in the last pass of water, before re-entering the tank.

Next, a hanging type of UV LED fixture for sterilization incorporates a ladder-hook, which allows the unit to be mounted on the back of the chamber. Easy access to the luminary allows for seamless maintenance. Hanging UV LED lamps are low wattage and feature compatibility with small aquariums.

It is important to consider that both types of UV LED sterilizers are supported by a conventional water pump and plumbing components. These parts help circulate water around the tank.

Determining Flow Rates

Maximizing exposure is key to boosting the effectiveness of UV LED lamps inside aquariums. Parasite control requires a slower flow rate, while bacteria and algae can be controlled at a slightly faster flow rate.

These settings should be carefully adjusted, based on the type of organisms inside the chamber. For inline UV LED fixtures, this is done by configuring the ball valve and bypass components.

Integrating LED Lights with Marine Equipment in Boats

Boat owners have very limited space to work with inside vessels. This is an issue for individuals who use different types of marine equipment at sea. Furthermore, boating expeditions that require large amounts of supplies or cargo need to incorporate space-saving features to ensure flexibility and comfort during the trip.

Read on to learn about how such techniques work and their applications in marine environments.

Space-saving Tips for LED Lights on Boats

One of the most effective ways to improve illumination on boats without taking up unnecessary space is through integration. This technique works by installing LED lights with equipment around the boat. For example, individuals may choose to setup LED fixtures inside speakers. This configuration can be used to boost aesthetics on the boat without needing to install a separate lighting system.

When selecting an LED light for boats, one can choose from a wide range of colors and effects. It is important to select a set of colors that will not obstruct or interfere with standard navigation lights, as required by marine regulators.

As a general rule, entertainment lights on vessels should be less powerful than external LED navigation lighting systems. Additionally, non-standard LED fixtures should not be mixed with navigation lamps to reduce confusion on the water.

Boosting Convenience and Safety

LED light integration is useful around frequently used boating equipment. Such components may include the mast, storage bins, seats and more.

LED fixtures can also be installed on boating racks and towers (such as a wake tower). This type of integration is particularly useful for LED spotlights and bars. From such elevated positions, individuals can easily direct light beams on the water.

Lastly, for inaccessible LED lamps mounted on towers or rails, long handles or remote switches should be used to improve light direction and beam manipulation. For more information on boat led lights visit the link here

Reusable LED Lights for Trawling on Commercial Fishing Vessels

Extended boating operations, such as commercial fishing and patrolling, require LED Lights support. The main issue with this need is lack of reliable power sources. Batteries are heavy and can be expensive to maintain a constant supply.

For trawlers, this concern is addressed through the use of glow sticks. The temporary units are secured on or near the hook for visual clarity, allowing marine creatures to see the bait and consume it.

Replacing Glow Sticks with Solar LEDs

For this specific application, relying on glow sticks is an extremely wasteful practice. The lights only last a few hours and are thrown away after use. Fishermen usually throw the flimsy light sources back into the ocean, while pulling lines back in the boat.

Jesse Senko, a biologist at Arizona State University’s School for the Future of Innovation in Society, wants to change this practice, by replacing traditional glow sticks with solar-powered LED lights.

The reason Senko chose solar-powered units is due to its reusability. When he interviewed local fishermen during trials for the lights at sea, boat operators clearly expressed that throw-away batteries are not sufficient for net or trawling lights. Inserting new power cells in demanding and wet conditions can be difficult. Furthermore, it cost money (and space for storing batteries on the boat) to keep the lights operational.

Net Lighting Requirements

In order for the lights to be useful on fishing boats, they have to be able to provide illumination for long periods of time – at least 12 hours. LEDs are perfect for meeting such stringent operational requirements. The lights consume very little energy, compared to incandescent and halogen lamps.

Furthermore, the solid-state luminaries can withstand rough impacts, which on a trawling vessel includes constant banging on the side of the ship, constant pressure, when deployed underwater, and corrosion from surrounding saltwater.




Transitioning from Metal Halide to LEDs for Shipyard Lighting Systems

Shipyard facilities require brilliant illumination inside the building, due to detailed maintenance, repair and restoration tasks that come with operations. Unfortunately, lights do not thrive well in such establishments. Shipyards are extremely humid, corrosive and flammable. Furthermore, the environment is filled with vibration from constant use of heavy-duty equipment. Nowadays, shipbuilding and repair businesses are transitioning from metal halide lamps to LED fixtures, in order to improve illumination inside the facility. This article takes a closer look at Donjon Shipbuilding and Repair’s adoption of boat LED lights.

Addressing Visibility Issues

The 200,000 square-foot shipyard facility boasts 125-foot ceilings to serve 1,000-foot long commercial vessels. Before transitioning to LEDs, the building utilized 266, 1000-watt metal halide fixtures. The high ceilings made the units difficult to reach for periodic ballast maintenance and re-lamping projects, which were frequent due to the rugged environment.

Furthermore, operators used the luminaries around the clock – catering to both daytime and nighttime workers. Starting the metal halide lighting systems took approximately 20 minutes per day. According to a technician working for the company, individuals were forced to use flashlights during work because general lighting was not powerful enough to facilitate accurate readouts on measuring devices.

Transitioning to LEDs

The shipyard business replaced the metal halide lamps with 79 LED fixtures, which surpasses illumination levels of the previous lighting system. Capable of offering 60,000 lumens of white light per unit, the high bay lights are highly energy efficient. Moreover, the LED fixtures are lightweight, streamlining access during installation. The high bay lamps operate on 480V and provide lighting efficiency rates at 115 lumens per watt.

To ensure consistent operation in extreme conditions, the units feature an ambient operating temperature range of -40°F to + 149°F. Overall, the new LED lighting system will come with at least 10 years of zero maintenance.

What are Wharf Lights for Marine Docks?

There are numerous types of lights to choose from, when lighting up a dock at night. Latest lighting trends include the addition of slim-profile LED lamps, which are installed on the side of walkways, and portable light towers for temporary illumination. Due to the limited, narrow space on marine docks, bulky outdoor lamps are not suitable for the area. To cater to space-saving layouts, some locations incorporate tall wharf lights for illumination.

Marine Wharf Lights 101

Wharf lights are unique looking fixtures that are designed to address the rough nature of marine environments. The lamp head is supported by a curved arm that is connected to the pole. Wiring is fed inside this arm (and into the foundational pole structure) for protection against saltwater corrosion.

As mentioned earlier, the head of the fixture is pointed down, towards the target area. Furthermore, it would be possible to install reflectors or covers over the lamp to prevent stray light beams from blinding pedestrians. A cage guard over the lens may also be used to prevent tampering, typically from birds attempting to perch around or on the pole.

Benefits of Wharf Lamps for Marine Docks

Wharf lights are usually mounted on tall structures, allowing more space for movement on the walkway. The pronounced curve of the lamp’s arm ensures light is casted over the target area.

For large docks with space for gatherings, up to four wharf lamps can be installed on a single pole. This further adds to the space-saving benefits of the luminaries, as operators do not have to allocate a pole for every lamp during installation. For marine docks with two walking lanes, two wharf fixtures supported by one pole is common.

Lastly, upgrading wharf lights with LEDs in an effective way to improve the lifespan, energy consumption and overall performance of the units.

Improve Security at the Shipyard and Boat Dock with Infrared LED Lights

Patrolling busy shipyard operations and congested boat docks is no easy task. Compared to land-based monitoring operations, there are several inaccessible sections of marine establishments that require the use of rafts, pulleys or transfer pods. Because of this, many marine-based businesses use infrared LED lights to improve night vision and security. When used with an infrared camera, individuals can monitor the location discreetly, using non-visible beams that are only detectable by the viewing device.

Types of Infrared LED Lights

Infrared LED lights for security applications at boat docks vary, depending on the type of monitoring being conducted in the area. An infrared LED spotlight is ideal for highlighting targets that are unreachable, far-flung or inaccessible (footage viewed on the camera). Typically taking on a handheld design, the units can be low voltage (12V/24V) and battery powered to meet the requirements of the marine location.

An infrared LED emitter or bar is perfect for monitoring wide spaces. The luminaries emit a non-visible flood beam that is capable of encompassing large targets. Taking on a slim design, the lights can be mounted on boats for patrolling covertly around shipyards.

An infrared LED strobe light is applicable for providing warning signals or notifications that can be seen clearly on monitoring systems and cameras. These compact units are mostly used for marking obstructions and can be solar powered or battery powered for installations in remote sections of the boat dock.

NDT and Thermal Monitoring

In addition to boosting security, infrared LED lights can also be used to support non-destructive testing (NDT) and thermal monitoring. Infrared non-destructive testing (IRNDT) refers to using thermographic instruments to measure and detect the response of certain materials, when exposed to external elements. IRNDT is suitable for uncovering cracks, stress, dents and inconsistencies on surfaces. For accurate detection, the type of infrared lamp used must be high-speed and highly sensitive.

How Does Saltwater Contribute To Corrosion On Boat Lights

Saltwater is one of the most devastating elements for boat lights and marine establishments close to the shore. Without proper protection, saltwater can cripple conventional lighting systems, resulting in premature failure, warping or discoloration of materials.

Saltwater Corrosion 101  

For electronics on the vessel, saltwater is also a powerful conductor of electricity. Without protective mechanisms in place, the presence of such elements could lead to electrolytic corrosion – also known as the process involving the breakdown of compounds via electric currents passing through surfaces.

Galvanic corrosion is another type of damage that can occur at sea. Unlike electrolytic corrosion, this form requires two dissimilar metals to be connected, with the presence of an electrolytic compound, such as saltwater or other corrosive agents (acid). Liquids that are not viable electrolytes for corrosion include steam, distilled water and fresh water. These types of liquids are so weak at enforcing corrosion that they are used to break up the onset of corrosive damage on surfaces.

Controlling Saltwater Corrosion

Now that you know the basic fundamentals of saltwater corrosion, it’s time to learn about preventive measures surrounding this type of hazard in marine locations. One of the most effective ways to deter saltwater corrosion on boat lights is by separating or isolating the metal from the corrosive compound. This can be done with special coatings or high-quality paint.

Ensuring saltwater does not build up on the vessel after use is another way to reduce corrosion. This is why people wash their boats with freshwater over land (don’t forget to dry the surface). When it comes to the construction of the lamp, entry points are commonly sealed with rubber components to prevent the ingress of saltwater. Lastly, it’s important to inspect the internal components of marine luminaries on a regular basis. Any signs of discoloration, cracking (on the cover, wirings, cords and lens) or tearing should be addressed.

The Advantages of Solid State Designs in LED Lights

The success of LED lights can be traced to its unique, solid-state design. Like solid-state hard drives, the units feature virtually no moving parts. By comparison, traditional luminaries, such as incandescent lights and metal halide lamps, are comprised of loose filaments, which makes them unstable and prone to premature failure (breakage) when exposed to rough conditions or treatment. Furthermore, without the use of toxic gases, solid state lighting is exponentially safer to handle and use.

How does solid state lighting improve LED efficiency and performance? Find out below!

Solid State LED Lights 101

There are several benefits that solid state designs bring to LED lights. One of these is an increase in lifespan by up to 50,000+ hours or 2,000+ days. The units are able to achieve this lifespan by reducing the wear and tear commonly associated with moving parts. Outdated lighting technologies resemble car motors, in a sense that they use a myriad of moving components that are susceptible to decay. This is why incandescent lighting can only reach roughly 3,000+ hours of use, while metal halide units come with around 20,000+ hours of use.

Solid state LED lights also offer energy savings, due to less effort requirements for illumination. Without the need to constantly generate movement, LEDs are capable of reducing energy consumption by a whopping 70 percent! This also makes the luminaries suitable for intrinsically safe lighting products that rely on low voltages during operation. In such hazardous environments, intrinsically safe LEDs operate at cooler temperatures, reducing the possibility of surface temperature-related ignitions.

Applications and Form Factor

If you look inside a fluorescent tube, you’ll notice that there’s a lot of empty space inside the unit. This is needed to promote gaseous reactions during illumination. But such chambers also take up a lot of space. This is where solid state LEDs really shine. The lights are extremely compact, consisting of tightly manufactured chips or diodes, neatly lined up on a board. The concentrated configuration offers more intense lighting with minimal space requirements.

For businesses and individuals with strict lighting needs, solid state LEDs have made illumination possible in extremely tight, limited spaces. In machining, operators are able to install the modern lights close to the working components. Moreover, they can withstand vibration for long periods of time without succumbing to failure. In medical labs and warehouses, LED strip lights are top choices for professionals. The units can be installed under cabinets, walkways, tables and other platforms that cannot accommodate large, bulky luminaries.
