Using LEDs to Transmit Wireless Data with Li-Fi

The Internet-of-Things (IoT) sector will revolutionize lighting systems by incorporating wireless features and sensors for network-based or automated operation. LEDs, with their energy efficient features and solid-state builds, is also set to become the lighting technology of choice around the same time the IoT industry hits mainstream.

Can LEDs help bridge the gap between the demand for wireless data transmission and IoT networks? Find out below.

LEDs and Li-Fi

Li-Fi, which uses light instead of radio frequencies (used by traditional Wi-Fi), was first introduced in 2011 at the University of Edinburgh, as an alternative to Wi-Fi. The protocol uses rapidly flickering light from a single LED to transmit data wirelessly. Called Visible Light Communication (VLC), Li-Fi leverages frequencies in the range of 400 and 800 terahertz.

The best way to visualize how Li-Fi works is by comparing it with light-based Morse Code. The diodes toggle at rapid speeds (undetectable by humans). This process, which is called on-off keying, facilitates the transmission of binary code to a receiving device. An alternative VLC method includes continuous signaling.

Combining Illumination with Wireless Data Transmission

Interestingly, according to researchers from the University of Edinburgh, LED fixtures can be used to light up a room and transmit wireless data simultaneously, without affecting illumination. Both VLC techniques mentioned above does not degrade LED performance (no dimming or color shifting).

The lifespan of the LED is also retained at 50,000+ hours. However, it is critical to highlight that such processes can contribute to a slight increase in operating temperature experienced by the luminary.

According to a recently published study (Perovskite Nanocrystals as a Color Converter for Visible Light Communication), scientists are incorporating a nanocrystalline structure (derivative of cesium lead bromide and nitride phosphor) in order to increase bandwidth capacity. As a result, data speeds of 2 Gbps and a bandwidth of 500 megahertz can be achieved.

omni-directional leds

Directional vs Omni-Directional LEDs

Traditionally, LEDs are directional light sources. Taking on a standard chip configuration, the diodes project beams at roughly 180-230 degrees. By comparison, incandescent and conventional bulbs offer omni-directional LEDs illumination, emitting beams between 270-360 degrees.

When choosing between the two designs, it is important to understand how the two options handle illumination.

Directional Lighting and Detailed Tasks

With a tighter spread, directional light sources provide more control over the positioning of the beams during illumination. This makes the configuration ideal for task, recessed and display lighting. Directional bulbs do not utilize reflectors to push the light towards the target area. As a result, less light is wasted during operation.

The proliferation of LED technology strongly relies on healthy consumer adoption rates. Since most individuals and businesses are used to omni-directional light sources (incandescent bulbs, fluorescent tubes and metal halide lamps), lighting manufacturers were forced to release innovative solutions for LEDs to meet such requirements. Specifically, engineers added reflectors and new designs that extend the angle of the beams, making them wider.

To ensure consistent performance, today’s lighting manufacturers trade in epoxy for silicone for robust thermal management. Silicone can withstand temperatures up to 200 degrees Celsius, while epoxy starts breaking down at 80 degrees Celsius.

Omni-directional LEDs Illumination and General Spaces

Omni-directional LEDs are suitable for wide-area lighting and outdoor locations. In order to get the most out of this type of light, it should be installed over large spaces, with minimal obstructions. Capping the light (without a reflector) would waste the stray beams, causing a significant loss in brightness. Lamps that require full, 360-degree illumination, such as strobe or emergency lights, can directly benefit from omni-directional lighting.

To suit omni-directional lighting preferences, LED bulbs typically incorporate a series of diodes, pointing at different directions. Initially patented under US patent number 5594433 such luminaries also use convex reflectors to promote even distribution.

boat dock lights

Types of Boat Dock Lights

Keeping boat docks safe starts with illumination. With adequate boat dock lights you can keep the location secure, discouraging criminals for tampering with valuable items on your boat. From a safety perspective, you can move around the dock and vessel freely with more confidence.

Keep reading to learn about the different types of LED lights for boat docks.

Configurations and Concerns

Boat dock lighting systems must be able to withstand rough treatment and unpredictable conditions. Because of this, it is important to make sure the LED light is waterproof and (ideally) corrosion resistant. When it comes to size, the units should be compact or low profile. This is because there isn’t a lot of space on boat docks. Lights that are bulky or intrusive could expose individuals who aren’t familiar with the placement of the units to accidents.

In some cases, the dock is so tight that installing LED lights on the actual walkway is not possible. For such concerns, it would be a good idea to install marine lighting systems under the dock, with the light shining outwards on the water. If the light is bright enough, the beams should reflect off nearby surfaces or the water, providing indirect illumination.

Types of Boat Dock Lights

Slim pendant lights that provide 180 degrees of light are ideal for just about any type of lighting configuration on boat docks. They can be installed along the floor boundaries and corners or wall mounted on the side of the dock. Another option includes LED strip lights. The units are extremely slim and are ideal for locations with limited space. They can also be equipped with an in-line transformer for low voltage requirements. Moreover, due to their thin design, people are less likely to trip or slip on them.

Lastly, for a traditional approach, one could setup a pole-mounted lighting system at the intersections of boat docks. This option is reliable but can be costly, as it requires investing in a sturdy pole and other electrical components.

vapor proof boat light

The Benefits of Vapor Proof Boat Lights

LED boat lights are prone to a plethora of corrosive substances out in the water. Because of this, lighting manufacturers have designed Vapor Proof Boat Lights that are corrosion resistant and waterproof. But what about damage caused by moisture and vapors? What can be done to protect marine luminaries from such destructive elements? Find out below.

Vapor Proof 101

Wet atmospheres can wreak havoc on standard lighting systems. The presence of moisture could trigger chemical reactions that breakdown surfaces and wire coatings. To ensure protection in wet environments, such as boat docks, ship yards and industrial sites, luminaries with vapor proof features must be used in the location.

Vapor proof lights are constructed differently, compared to standard lights from mainstream hardware stores. The socket and wiring are protected from moisture, fumes, dust and rain. In other words, the critical components of the fixtures are sealed to prevent unwanted contaminants from entering. Traditionally, the lamps are housed in thick glass, which reinforces its sturdiness in marine or wet locations.

It is important to consider that vapor proof lights can help boats and businesses maintain consistent power usage, resulting in long-term operational reliability and savings. Damaged lights have a tendency to consume large amounts of power over time. By protecting the internal components of lights via vapor proof designs, they can operate optimally without meticulous maintenance.

Do I Really Need Vapor Proof Boat Lights?

The question that most boaters have is whether or not vapor proof lights are really important for marine lighting systems. For rugged marine sites, the answer is yes. For example, vessels that are used for dock cleaning projects can benefit from vapor proof lighting. In addition to preventing saltwater corrosion, the extra layer of protection prevents the buildup of moisture caused by steam jets, which can carry aggressive chemicals from cleaning solutions.

For mainstream, consumer boat lights and locations, vapor proof luminaries are not vital to maintaining illumination. However, this does not mean that you can’t use them. Vapor proof units are used in car washes, processing plants, parking lots, warehouses, swimming pools, kitchens and auto repair shops. They come with numerous applications outside of boats and marine locations.

With that being said, it’s common for boaters to use vapor proof lighting for peace of mind. If you’re constantly replacing your lamps due to the presence of a range of destructive elements that go beyond water, such as dust and harmful fumes, vapor proof lighting might be what you need.

White vs Colored Led Boat Lights

Choosing between white and colored led boat lights can greatly affect your experience on the water. The two options vary in applications, from safety lighting to personal preference. Most consumers are not aware of such benefits, which limits the lighting system’s integration with their boating activities.

colored led boat light

White LED Boat Lights

White LED lights are the most common luminaries found in boats. They only emit one color and are mainly used for clean aesthetic designs and mid-to-long range viewing. Moreover, the units can be used to focus on specific targets in the water. White LEDs come with extended lifespans of up to 50,000+ hours and feature sturdy, solid state construction. They are extremely compact and are ideal for lighting up docks, ladders, stairs and the frame of vessels via strip lighting systems.

 

White LED units for boats come in a range of color temperatures. At the low end of the scale, one can find warm white light, which resembles yellowish light coming from an incandescent light source or natural candle. As you go up the scale, light turns from dark yellow to sharp white. LEDs with high color temperatures come with a bluish white color. For bright illumination, white LED boat lights with high color temperatures are the way to go. They are also safe for use in dark waters, when indirect, passive lighting from docks, roads and city lights are unavailable.

Colored LED Boat Lights

Colored LED boat lights are capable of emitting up to 16 million different color combinations. The units offer the same extended lifespan benefits and solid state construction as white LEDs. However, they come with more operating components, such as remote controllers and components that allow the luminary to shift colors. Using red, blue and green colors, the lights are able to light up a boat with an array of dazzling combinations.

Aesthetically, colored LED lights can make a boat stand out from other vessels at the dock. For anglers, some use green lights to attract large fish at night. This practice is mostly applied to spotlights and submersible units. RGB boat lights can also be used to comply with certain regulations at sea. Referred to as navigation lighting, the units serve as early warning systems for other vessels in the area.

To conclude, choosing between white and colored LED boat lights highly depends on how the luminaries will be used on the boat. To prevent premature failure during operation, don’t forget to make sure the units are waterproof and corrosion resistant.  To learn more about Boat Lights visit Larson Electronics LED Boat Lighting.

LED Lights Aren’t Just for New Boats

Makers of new boats are always in a constant race to bring to the audience the latest and best in reliability and performance enhancing marine technology in order to stay ahead of the competition. Among the many new technologies boat manufacturers have embraced to make their vessels more original and efficient, LED lighting systems have proven to be one of the most effective. LED lighting has proven to be far more efficient than the traditional incandescent lamps once standard on new boats, and their cooler operation and highly long operating lives have also served to further add to the savings potential they provide. The result at the end has been that new boats equipped with LED lighting systems are more efficient, cost less to operate, and require less maintenance to keep operating at their most efficient.

Some boat productions take the installation of LED’s a step further and add solar power options as well. Some solar power systems harness the power of sunlight to help replenish battery banks during sunny hours, and when combined with the extreme efficiency of LEDs provides a one/two punch that really puts a dent in the cost of producing onboard power. In fact, some smaller LED fixtures like those used for walkways or deck illumination can even be completely independent of the electrical system and run off their own built in solar charged battery, much like those trendy solar powered landscaping lights many homeowners have become fond of using. This last option is particularly attractive to owners of sailboats who have to rely almost entirely on Gensets and power stored in battery banks for their lighting needs.

One of the really best things about LED lighting is that it is not only available to builders of new boats. Owners of older boats built before the introduction of LED,s can benefit as well and can greatly improve the efficiency and performance of their vessel in less than a day with an upgrade to LED fixtures. Most LED fixtures designed specifically for boating applications are intended to be direct replacements for many types of existing incandescent fixtures. Because of this, it is possible to find LED fixtures that will bolt up and wire in without the need for any modification to your existing mounting setup at all. Because LEDs draw so much less power, you won’t need to worry about running heavier wires or increasing the load carrying capability of your breaker systems either. visit this website here!

LED lightingLEDs can be used in pretty much any place a standard light fixture is installed. They can also be used to create some innovative and unique lighting setups to provide a custom lighting system. For example, many boaters like to use dim red lights in the cockpit while navigating at night because they feel it helps to protect the eye’s ability to acclimate itself to dark conditions. If you’ve ever gone from a dark room to a very bright room, or had a camera flash go off in your face unexpectedly, you can understand how easily a bright light can momentarily blind you once your eyes have become used to dark conditions. LED cockpit lights are available that can be connected to a multi-position switch and toggled between a choice of colors for just this purpose. These lights can produce either red light for night time navigation or normal white light when preserving your natural night vision isn’t so important. read more from http://www.thewhig.com/2017/02/10/shedding-light-on-the-terms-lumens-kelvin-and-led

All in all, LEDs offer a far more efficient and durable alternative to traditional incandescent boat lights that can benefit just about any boat of any size regardless of its age or design.

How to Convert Your Boat to LED Lighting

You’ve considered running the Genset (noisy) more, another solar panel (somewhat pricey), or are maybe even ponying up the Benjamins for a wind generator (very pricey and somewhat noisy). It’s not as though you need a lot of power you tell yourself. All you want to achieve is more time cruising and less time at the dock or running the Genset. Before you jump in, I have a more cost-effective solution for you. Enter the boat LED. read top article!

LED is an acronym for Light Emitting Diode. They are an electronic device that generates light and the technology has finally matured enough to make them bright enough, the right color (early white ones were very bluish in their light emission), extremely energy efficient, and quite long lived.

The intensity of light from LEDs is now surpassing incandescent and halogen bulbs.

The colors available are varied but they can now be had in a color referred to as “warm white”. This is a reference to the light color, which tends to be a warmer golden color, rather than the old blue white.

Energy consumption is frequently measured in milliamps. At 12 volts, a 1.3w LED cluster is drawing approximately 110 ma. Figure the average CFL bulb draws about ten times that amount but the LED is generally free of or contains very minimal amounts of mercury (look for a RoHS certification).

Expected service life is even more interesting. A decent LED should have a minimum service life of 50,000 hours. If you left the light on that translates to almost eight and a half years on constant duty. This means it will be ultra rare that they will need changing. This is especially nice if you have to climb to replace them.

So how do you replace the lighting on your boat with them? One way would be to replace all the fixtures on your boat with dedicated LED fixtures but the price adds up very quickly and, contrary to what current marketing may like, you may actually like your current fixtures. The simple method is to simply replace the existing light bulbs with LED equivalents. If you have housings that use a G4 halogen bulb, for instance, you have lots of options for G4 LED replacements. You’ll only be limited by the space for the bulb and how bright you want it. Pull the halogen out, plug in the LED G4 marine led replacement, repeat as necessary with the other housings and you’re done. It really is that simple. Sure beats wiring another solar panel or wind generator, doesn’t it? check other source like http://www.larsonelectronics.com/c-277-led-boat-lights.aspx

Other bulb options exist, not just G4 LEDs. The 1156 LED, 1157 LED, and a number of others are available. The toughest part will be for those rare cases where a 32v electrical system exists (some of the larger early Chris Crafts are an example). 32v is too high for most the 8-30v LEDs and too low for the 120v LEDs. 24v systems can use the same LEDs that 12v systems do, in most cases.

Quality varies, but even most the stuff coming out of China now is ever of pretty decent quality. I’d just make sure they have the European CE and RoHS certifications.

LEDNow, I have a point to be careful of. Be very careful with the navigation lights. There are VERY few bulbs out there that are actually approved by the USCG (United States Coast Guard) for use in navigation lights. There are some, but they are few and far between. Navigation lights are certified as a combination of bulb and lens and consequently, some combos don’t meet minimum Coast Guard requirements. Furthermore, if you were to be in a collision and the insurance company found out that it was a non-approved combination in your navigation lights, you could face the possibility of having your claim denied. Not a good situation to be in. Dedicated LED boat lights navigation light fixtures are available as are a few approved LED navigation light bulbs.

So, change those bulbs first before you jump into more drastic measures and happy cruising!

Choices in LED Lighting for Boats

If you’re a boat owner, you know that having proper lighting is important. Not just emergency lighting, but lighting for certain times of the day or night and even aesthetic lighting are important. Thanks to the energy savings, size and efficiency of LEDs, there are many new choices in LED lights for just about any size or type of boat. There are so many options from the Internet, all you have to do is give some time to read the information which are very important in your future purchases. Let’s look at some of the choices.

Floodlights are a critical emergency lighting option for any boat. With LED floodlights, you can have brighter style in a smaller form factor. Floodlights are often used to light up areas outside the boat and on the water, whether to look for someone or something lost overboard or for signaling purposes, floodlights are always important to have on any boat. There are some companies which now make LED floodlights that are waterproof and are compatible with most popular portable marine battery sources.

Interior boat illumination is also another aspect that LEDs are taking to the next level. Now, boat owners can light up the inside of their boat with low energy LED light strips that can light up walkways, hallways and other areas of the boat where it may be dark at night. The lights can be an ambient blue or a more noticeable red or white light, whatever is most appropriate. There are still boat owners that don’t know what to use for their lighting, this is not the best time for them to know and create some ideas for their business.

Some boat owners use LED options for purely aesthetic reasons. For example, you may have seen boats that are lit up in different colors at night. Some boats even have LED light strips around the outside of the boat, but underneath the water, giving the water that surrounds them a glowing effect.

For more practical uses, LEDs are a great way to enhance your portable lighting options. On the bridge of the boat, you are always recommended to have portable flashlights. Now, you can make these lights more cost efficient, more portable and easier to maintain by replacing traditional flashlights with LED based options. Not only are they cheaper over the long run, but they are brighter and smaller.

LED lightingLast but certainly not least, you can further enhance your boat’s lighting by incorporating solar powered LED lighting options. There are many types of solar powered lights, from large floodlights to portable lights. With solar power, you can be thousands of miles away from a store where you can buy batteries, yet still have plenty of light thanks to the power of the sun. visit http://www.larsonelectronics.com/c-277-led-boat-lights.aspx today!
