DIP LEDs

DIP LEDs vs MCOB LEDs for High Bay Lighting Systems

LEDs come if various shapes, sizes and designs. Over the years, advancements in LED technology have ushered in new designs, resulting in wider lighting applications. Types of LEDs that are available today include Dual In-line Package (DIP LEDs), Surface Mounted Device (SMD), Chip on Board (COB) and Multiple Chips on Board (MCOB).

DIP LEDs

Most people’s experiences with LEDs are with lights that incorporate DIP diodes. These are capsule-like diodes that can be found in mainstream electronics, typically serving as indicator status lights. Colors to light beams are applied by changing the color of the diode, which serves as the lens and protective cover. For robust illumination, it is possible for some LED lamps to utilize more than one DIP diode. This practice is common in LED flashlights and other types of portable fixtures.

For high bay LED lights, DIP LEDs are rarely used due to inefficiencies and lack of focus. Because the lamps are installed at heights between 8 and 25 feet, a more powerful LED design is required. If DIP LEDs are to be applied to high bay lighting systems, the lamp would heavily rely on reflectors (and other lighting components) for proper beam placement.

MCOB LEDs

MCOB LEDs are recommended for cutting-edge illumination in industrial sites. These chips are made up of several COBs within cups that are installed on the board. With MCOB LEDs, lumen and CRI ratings (in some cases, as high as 90+ CRI) are on the upper end of the scale. Furthermore, operators are provided with more control and choices over color temperature.

Modern high bay LED lights are likely to adopt MCOB or COB LEDs, due to the type of beam angles the chips are capable of supporting. This type of LED can be found in PAR, BR and MR bulbs, as well as tunnel lighting systems; suggesting that the technology is flexible in creating flood (wide) and spot (tightly focused) beam angles.

LED Lights for Railyards

LED Lights for Railyards and Industrial Railway Networks

Railyards are essential to economic growth. Such facilities are responsible for transporting large amounts of materials, from grains to fuel, across the country. Railway networks operate around the clock, often resorting to nighttime operations to avoid congestion in highly populated areas. Because of this, the work site must be properly illuminated. Over the years, a handful of companies in North America have switched to LED lights for railyards, due to their ability to illuminate large spaces in an energy-efficient manner.

Light Towers, Wall Packs, High Bay LEDs 

Railyards are known for their rugged nature, due to constant vibration present in the area. For illumination, such outdoor locations typically deploy elevated lighting systems around the site. LED lights mounted on poles are the most common type of fixtures used by operators today. Permanent LED lamps can be installed along the railways, highlighting crossings, cautionary signs and critical connections.

Loading docks may utilize high bay LEDs for overhead, wide-area illumination. This type of LED fixture can be mounted on ceilings within the delivery bay. The exterior of buildings around railyards should also be properly illuminated, which support ongoing railway operations. Wall pack LED units perform well for such applications and can be setup along roofs (for down lighting) or along boundaries (for up lighting). 

Railyard LED Adoption

Railyard operators are slowly (but surely) transitioning to LED lighting systems. Norfolk Southern Railway, a Class I railroad system based in the US, is an example of a leading establishment in the industry currently pioneering the adoption of LED Lights for railyards.

The company previously relied on metal halide fixtures for illumination. As an upgrade, the establishment incorporated high mast LED units with a 60-degree beam spread and an expected lifespan of 50,000+ hours. The LED fixtures are mounted on poles, which provides a spacious working environment on the ground.

Primary vs Secondary LED Optics

LEDs are equipped with unique designs to promote intense and even light distribution. Called optics, most cutting-edge LED units feature a primary and secondary component, depending on the light’s applications. Read on to understand how optics improve LED light performance.

Primary LED Optics

The first set of LED optics can be found on the diode. This primary component can be a compact dome, covering the chip and other internal components of the package. In LEDs, primary optics help improve intensity during use. However, most luminaries still need another set of optics to further increase the accurateness of the light beams.

It is also important to consider that LEDs provide directional illumination, usually at 180 degrees. By comparison, traditional lighting systems, such as incandescent lights, offer full, 360-degree illumination.

Secondary LED Optics (Reflectors)

In LEDs, secondary optics are components that help improve light distribution. Such features can be found in the outer part of the primary optics (but still inside the light). An example of secondary optics is the use of reflectors.

Reflectors are shiny coatings or materials surrounding the diodes or chips. Both components should be as close as possible to each other, in order to ensure robust performance. To decrease the risks of electrical damage, an insulating component should be applied between the board or set of diodes and the reflective material.

While primary optics are usually more common in LEDs, secondary lighting optics are frequently present in a wide variety of lights and bulbs, including metal halide lamps.

Lastly, the lens component on LED units may address other aspects of illumination. In addition to providing protection for the fixture, the lens also controls illumination. For instance, a frosted lens can reduce light glare. This type of lens is ideal for small spaces, roadside construction and illumination in public locations.

data center lighting

How is LED Lighting Used in Data Centers?

As cities and businesses become connected and increasingly reliant on cloud-based solutions, data centers have started to proliferate rapidly worldwide. The power-hungry establishments require energy-efficient LED lighting systems in order to reduce operating costs, which is a practice recommended by the Telecommunications Industry Association.

High Bay LED Lights

For general locations in data centers, high bay LED lights are commonly used. This type of unit can be mounted close to the ceiling in elevated positions. The luminaries illuminate large servers, hallways and aisles.

High bay LED units can be round or square, depending on the preferences of the operator. Even light distribution is key to optimized illumination in data centers using this type of light.

Alternatively, data centers may also incorporate recessed panel lighting systems in the area. This type of LED fixture is suitable for rooms with low ceilings. Furthermore, LED variants are designed to replace traditional fluorescent recessed lights, which are prone to breakage and flickering (during startup).

Workers overseeing data centers should have their own portable LED light, which is used for inspections. Pen lights, flashlights and lanterns are typically utilized for such tasks. Heavy-duty maintenance or setup may require more powerful lighting options, such as compact LED light towers or LED drop lights, which can be mounted on racks.

Outdoor LED Illumination

Security around data centers is generally tight, since the building hosts and processes large amounts of sensitive information. In order to boost security in the area, operators can deploy LED lights in parking lots. The lights may also leverage motion sensors or day/night sensors for automated illumination.

Other LED lighting used for general illumination outside of the data center include LED wall pack lights, which are mounted directly on the wall of the building, with the beam pointing upwards. LED flood lights are applicable to landscapes and entrances. If you are looking for top industry led lights visit Larson Electronics.

LED Lights and Water Well Exploration, Excavation and Inspection

LED Lights and Water Well Exploration, Excavation and Inspection

Industrial wells present a myriad of challenges for operators. Such locations must be excavated and maintained rigorously, in order to prevent accidents. Depending on the type of well or water line, the area can be high pressure, murky and hazardous. Due to the dangerous that come with industrial well operations, powerful spot lighting, such as LED lights, is needed for illuminative safety.

Compact, Waterproof and Corrosion Resistant

Like underwater LED lights, industrial well lights must be capable of withstanding similar rugged elements associated with marine-based locations, including strong water spray, high pressure jets and corrosive substances. LEDs are ideal for this type of work, because the solid-state units can handle rough contact.

The type of LEDs used for industrial well operations include slim LED spotlights or droplights. Its compact form factor allows individuals to lower the unit down manholes, tunnels and tight passageways. A long cord managed by a reel is typically attached to the light, for control of the process.

Operators may attach a downhole camera with the LED spotlight for safe inspection of wells from the ground. Additionally, other types of attachments can also be used, such as temperature sensors, pressure readers, infrared or UV LEDs for inspections and etc.

Manhole LED Lights

For industrial well projects that require human operators to be present in the location, manhole LED lights are highly recommended. This type of LED light sits on top of manhole openings, which can be found in sewage treatment plants, silo storage centers, water wells and more.

Manhole LED lights are useful for marking the entry or exit point of underground well sites. This is important, due to the dark and confined nature of wells.

Once inside the well, workers can revert to their portable LED spotlight for illumination. The long beam of the units ensure far-flung or out-of-reach targets can be seen effectively.

Permanent LED Spotlights

Best Locations to Install Permanent LED Spotlights

LED spotlights are primarily designed for focused lighting setups. By definition, an LED spotlight is a luminary consisting of a beam spread that is less than 45 degrees (width). With such tight beam characteristics, the units perform well in landscaping, flagpole lighting systems and etc.

Learn more about locations that can benefit from permanent LED lighting installations below.

Directing Light Beams

Any area where detailed tasks are conducted on a regular basis may find LED spotlights advantageous. Moreover, an object that requires highlighting from a considerable distance may benefit from an LED spotlight. Examples of such locations include outdoor signs, building perimeters and more.

For indoor locations, most compact LED lighting systems are installed in a recessed configuration. This helps keep the beam tight, with minimal light trespass in the surrounding environment. On a broader scope, recessed spotlights are categorized under downlights, which are basically lights setup from a high location, with the beam pointing downwards.

Lighting Trims

Unlike portable LED spotlights, permanently installed LED lighting may come with trimming components. In lighting systems, the trim can be a ring or other parts of the unit that improve beam direction. An example of a useful trim for LED spotlights is a baffle. The component is a rigid texture around the light head, helping diffuse light beams. Baffles also decrease the creation of glare. Lighting trims can be circular or square, depending on the illuminative needs of the area.

Another useful trim for permanent LED spotlights is an eyeball or eyelid. Such components come with two features: beam direction and coverage. To position an LED spotlight with an eyeball, operators manually adjust the light head to a preferred direction. This adds functionality to the light. If the lighting conditions are too bright for the desired application, it would also be possible to cut the beam, by tilting the eyeball component upwards.

UV LED Spotlights and Animal Tracking Applications

Ultraviolet (UV LED) light has numerous applications in the fields of criminal identification, sample analysis and law enforcement. This type of light, which comes in a wide range of wavelengths, depending on its use, can also be applied to boost non-invasive animal tracking practices.

When used for such purposes, a UV LED spotlight is frequently utilized, due to its ability to emit a concentrated beam at far-flung targets with ease.

Pest Control

Businesses that specialize in pest control for industrial locations, such as warehouses, silos and food storage centers, can directly benefit from UV LED lighting. Inspectors may use a portable UV luminary to detect the presence of rats, squirrels and other gnawing mammals, as some hair strand profiles appear bluish-white, under the presence of UV light.

In application, an inspector could look for such elements in food sacks and containers without needing to perform lengthy tests on the product and environment. Furthermore, reaction with the UV light is instant.

Pet Rescue Operations

Animal rescue centers, fire fighters and pet care facilities can also use UV LED lighting to identify and track various creatures. Instead of looking for loose hair strands, inspectors focus on detecting illuminative reactions with urine. Creatures with protein-rich diets release urine that glow under the presence of long-wave UV bands.

This type of detection is beneficial because animals like to mark territories using urine, which cannot be detected naturally (without cutting-edge equipment). Additionally, a powerful UV LED spotlight beam is recommended for such applications, as some domesticated pets, such as cats, like to climb hard-to-reach locations.

With a UV LED spotlight, inspectors can assess unsafe areas without the use of ladders, ropes and harnesses. For instance, a specialist may stand at the entrance of an attic or basement and perform a quick and thorough sweep of the location.

LEDs vs Filament-based Insect Deterring Lighting

LEDs vs Filament-based Insect Deterring Lighting

Insects are naturally attracted to artificial light sources at night. The creatures are drawn to heat released by the units, as well as their capabilities that mimic the illuminative qualities of the sun and the moon.For homes and businesses, reducing the build up of insects starts with choosing the right type of insect deterring lighting. Read on to learn more about how LEDs and traditional luminaries differ in attracting bugs at night.

Comparing Artificial Light Sources

According to a new study by the Natural Environment Research Council (titled: Experimentally comparing the attractiveness of domestic lights to insects: Do LEDs attract fewer insects than conventional light types?), insects are less attracted to LEDs by up to four times, compared to filament-based lights. Moreover, LEDs are also more reliable in this manner than fluorescent lamps.

When it comes to specific species of insects, only 2-3 percent of creatures in the genus Culicoides were attracted to LED lamps. However, over 80 percent of the insects were drawn to the filament-based units. Compact fluorescent fixtures accounted for 15 percent of the activity during the experiment.

Reducing Heat Signatures

While some insects are attracted to the actual light produced by the fixture, others are interested in heat. This is why 12v LED lights are very effective for comfortable, outdoor illumination. The units generate up to 50 percent less heat during operation, than filament-based lighting.

Where you install the lights may also affect the way insects gather around the location at night. It is recommended to setup LED bug lights around areas with high activity. Standard or filament-based lighting systems can be installed around low activity locations, which may help push bugs out of the space.

For best results, it is advisable to first determine the type of insects populating in the location. This information can be used to select the characteristics of the LED fixture (color temperature, wavelength, lumens and etc).

What You Need to Know About LED Lights and Heat Production

What You Need to Know About LED Lights and Heat Production

Heat negatively impacts the performance of industrial lighting systems. Traditional lighting technologies, such as incandescent and metal halide lamps, are notorious for producing large amounts of heat during operation. As a result, less energy is converted to light, contributing to more heat (and a rise in temperature) in the surrounding environment. LED lights address this issue through their solid-state designs.

 

Managing Stable Operating Temperatures

 

It is important to point out that LEDs do indeed produce heat (contrary to popular belief). Though without the use of filaments, LEDs do not generate large amounts of it.

 

By comparison, incandescent units emit up to three times more heat than LEDs. One of the main reasons LEDs operate cool is due to low energy consumption. Moreover, the light source does not produce infrared radiation during illumination (not applicable to infrared LEDs). Infrared bands are responsible for the presence of heat surrounding conventional lighting systems.

 

LEDs may also come equipped with a cutting-edge heat sink to improve heat management.

 

Thermal Heat Sinks

 

A robust heat sink can help manage thermal fluctuations in LEDs when in use. The component works by directing heat towards a path for active cooling. Heat can be directed outside of the fixture, wherein the surrounding environment helps cool down the unit. The three methods applied to this process includes: convection, conduction and radiation.

 

The material used also affects the efficiency rate at which heat is managed within the LED lamp. For low-cost heat dissipation, copper is a common material applied by lighting manufacturers. Aluminum can also be utilized for such purposes.

 

Compact LEDs typically incorporate thermoplastics or ceramics. This allows the luminaries to be installed in tight locations and high-heat environments. In particular, thermoplastics are useful for intricate lighting designs due to their small size. LED heat sinks may be coated to improve performance.

When is the Best Time to Buy LEDs

There are several factors to consider when transitioning from incandescent or halogen fixtures to LEDs. Cost, compatibility and performance are aspects that are important to get right, for a successful transition.Focusing on the first factor, many people want to buy LEDs but are concerned about the initial, high upfront cost. Read on to learn more about how LED prices could shift in the next few years.

Price and Timing

According to a new study published in Environmental Research Letters (Replacement policy of residential lighting optimized for cost, energy, and greenhouse gas emissions), the reason for transitioning to sustainable LED fixtures may determine the ideal time to make the move.

Researchers applied life cycle optimization frameworks to build a model for the study. The results of the trials showed that individuals who are concerned about high CO2 emissions and saving the environment should transition to LEDs as soon as possible.

However, people who are more interested in reducing their energy consumption and decreasing their monthly energy bill at home, should wait a bit longer.

But is this really the best option to take for people who want to decrease energy use at home?

Immediate Energy Savings

The authors of the study cited that LED Lights tech will go through rapid development in the next three years, between 2017 and 2020. This will affect its performance (increase), as well as its price (decrease).

With this in mind, this three-year window (and beyond) is an optimal period to buy LEDs.

Furthermore, LEDs offer immediate savings after installation, through reduced energy use, which will accelerate one’s return on investment (ROI). The modern, solid-state fixtures also last longer than traditional lighting technologies (the units come with a lifespan of 50,000+ hours), which could decrease replacement costs, from a long-term perspective.
