Creating a brighter world with smart glass engineering and innovative light-based technologies. The promise of greater efficiency and reliability over a long lifetime has enabled LEDs to penetrate almost all lighting markets. Several challenges impede mass adoption of UV LEDs, specifically for those in the UVB (280nm – 315nm) and UVC (100nm-280nm) spectral regions.
In this article, I’ll review recent research that aims to improve near UV LED (NUV-LED), and deep UV LED (DUV-LED) technology. NUV-LEDs encompass the UVA spectral range (315nm – 400nm) and parts of the UVB spectral range.
UV LEDs on the tail end of the blue spectrum, specifically those at 365nm and 385nm, are easier to manufacture and are currently the most efficient of the UV LEDs. Applications that use NUV-LEDs currently represent the largest segment of the UV LED market, with UV curing driving the bulk of that growth.
While NUV-LEDs are currently more efficient and affordable than deep UV LEDs (DUV LEDS), researchers still seek to improve performance and reduce manufacturing costs.
At the deep end of the UV spectrum, applications include germicidal sterilization equipment, rapid surface curing systems for inks and lacquers, and spectroscopy and fluorescence instrumentation. The potential applications and market size are spurring researchers to overcome these challenges by exploring different semiconductor and substrate materials and refining the manufacturing process.
Crystal IS first pioneered native bulk aluminum nitride (AlN) substrates, with them they were able to achieve higher light outputs and extend the projected lifetime of the LED.
While native AlN substrates promise better performance, they are estimated to be between 2.5x to 4x more expensive than sapphire substrates. Also at Photonics West 2015, research from the Ferdinand-Braun Institute and Technische University explored advances in the development of AlGaN-based LEDs that emit in the UVC spectral region. Earlier this week, the European Union’s Restriction of Hazardous Substances (RoHS) directive that permitted the use of mercury in high-pressure mercury vapor lamps expired.
UV LEDs comply with the US Energy Policy Act and European Union’s RoHS directive and do not contain mercury, which is often found in CFL light sources. This is a great article from UV+EB Technology on the technological advances that have accelerated UV LED adoption for ink curing.
The compact size and efficiency of LEDs make them perfect candidates for spectroscopic instruments.

Covering existing floorboards with a hardboard underlay is an alternative to floor sanding as a way of ensuring a smooth, flat surface ideal for thin sheet floor coverings. An acrylic floor finish is utilized on such floors that are made of quarry tile, sealed wood terrazzo, brick, flagstone, concrete, rubber, asphalt, vinyl composition or just vinyl.
Maintenance is rather costly of these kinds of floors covered with an acrylic floor finish, as well as time consuming.
An acrylic floor finish is fine if you are up to doing that much constant work on your floors to get them to stay clean and gleaming well. Silikal is composed of methacrylate resins for patch repair, and they then have created enhanced MMA that puts out a tremendously beautiful finish on floors in the above stated facilities as well as offices and office parks, auditoriums, and actually any industry whose floors need the vast protection that Silikal can bring to them.

LED manufacturers are struggling to improve light output and efficiency while at the same time increase the reliability and useable life of the LED.
Closest to the visible spectrum, their long wavelengths are often used in applications that require fluorescing, like counterfeit currency detection and nondestructive testing.
Research and technology developed for visible LEDs provided an existing infrastructure that NUV-LEDs manufacturers could work from. I recently attended Photonics West 2015; during the presentation “Improved UV LED Performance Using Transparent Conductive Films Embedded Plasmonic Structures” researchers shared a novel fabrication process that improved the light extraction efficiency of the LED. DUV-LEDs in the 250 nm to 280 nm spectral range are used for water purification, food, and medical sterilization, and for air purification within HVAC systems.
Researchers continue to explore other substrates and improve manufacturing processes to reduce costs.
They identified success in reducing defects in the semiconductor layers by applying the epitaxial lateral overgrowth (ELO) technique on micro-structured AlN layers. Mercury is no longer allowed to be used for “general purpose” lighting as of April 13, 2015. Their adoption will accelerate as manufacturers improve efficiency and can offer them at a more affordable price. Lower costs, better thermal management, and secondary optics that improve irradiance make UV LED systems a viable option for UV curing.
It can be difficult to understand the differences between models and how they work in real operating conditions.
In this Laser Focus World article, they review several applications and the benefits LEDs provide, which in some cases can reduce instrument costs by 40% to 80%. In this article, the authors compare UV LEDs to xenon flash lamps for DNA purity and concentration measurements. The introduction of new technologies brings both exciting opportunities and complex challenges. When an acrylic floor finish is used to call forth high initial gloss, as well as durability after it is put on the floor, then the user will use what is known as spray buffing. At various times, the floor must be completely stripped as the acrylic tends to turn yellow after so many uses.

However, much less work along with much less time invested in floors is yours with the use of Silikal. Interestingly enough, Silikal can be laid on any substrate floor and it will work the same, providing more than a lifetime of high impact resistance as needed, along with a totally seamless installation that positively will not encourage any mold or bacteria since in actuality it is totally non porous.

They’re also used for lithography and for curing industrial coatings, adhesives, inks, and paints.
NUV-LEDs based on a GaN substrate have demonstrated external quantum efficiencies (EQE) of ~40% at 645nm and EQE of ~60% at 400nm. System miniaturization and faster line speeds have improved productivity, and LED efficiency has lowered energy costs. Researchers spin-coated silver nanoparticles onto the LED substrate before depositing the indium tin oxide layer. Most performance issues stem from minor impurities and crystalline structure defects in the substrate. While this doesn’t impact “special purpose” lamps that are used for industrial applications, it is a reminder that organizations worldwide want to shift to more environmentally friendly solutions.
In this white paper, Lumileds explains how to make an accurate performance assessment from an LED datasheet.
As the Manager of Research and Engineering, Adam works closely with our engineers and production team to develop new glass compositions that meet our customer's color and transmittance requirements, while ensuring efficiency. For over 85 years we have helped lighting engineers develop technical and industrial glass solutions that direct light, focus it, color it, or protect its source. Once stripped, it has to be allowed to completely dry, followed by a good liberal coating of the finish. Because this type of flooring is best suited for a commercial projects that needs an anti slip flooring, various anti slip levels can be achieved.
While visible LEDs are rapidly being adopted, manufacturers have been slow to embrace LEDs that operate outside of the visible spectrum such as UV LEDs.
Lighting manufacturers cite the initial and total cost of ownership as one of the primary obstacles preventing them from making the switch. This created a suspended nanoparticle layer that increased light output by 1.4 times the magnitude of conventional NUV-LEDs. Other challenges include reducing resistance in the current spreading layer and enhancing light extraction from the chip.
During their presentation “High-efficiency UV LEDs on sapphire,” they explained how they were able to reduce defects and improve performance by controlling the interface between the LED and the substrate crystalline structures. Together, we harness these technologies to create truly innovative products that create a better and brighter world. However, no matter what, the maintenance program calls for damp mopping always followed by spray buffing with some kind of speed buffing machinery. As you can see, even safety is considered high on the list of advantages that can be gotten through the use of Silikal. Chances are great that you have seen them in the hallways of various high traffic areas, as they are commonly utilized in schools, supermarkets, food service facilities, hospitals, malls and department stores.
