Although ultraviolet light is potentially dangerous to living organisms in daily life, such as sunburn, ultraviolet radiation can provide many beneficial effects in various fields. As with standard visible LEDs, the development of UV LEDs will bring more convenience to many different applications.
The latest technological developments are expanding some of the market for UV LEDs to a new level of product innovation and performance. Design engineers are noticing that new technologies for UV LEDs can generate huge profits, energy, and space savings over other alternative technologies. The next generation of UV LED technology has five important advantages, which is why the technology market is expected to increase by 31% over the next five years.
Wide range of uses
The UV spectrum contains all wavelengths from 100 nm to 400 nm in length and is generally subdivided into three categories: UV-A (315-400 nm, also known as long-wave UV), UV-B (280-315 nm, also known as medium-wave UV), UV-C (100-280 nm, also known as short-wave UV).
Dental treatment instruments and counterfeit use are early applications of UV LEDs, but the performance, cost, and durability benefits and prolonged product life are rapidly increasing the use of UV LEDs. The current uses of UV LEDs include: optical sensors and instruments (230-400nm), UV identification, bar codes (230-280nm), surface area water sterilization (240-280nm), identification and body fluid detection and analysis (250-405nm), Protein Analysis and Drug Discovery (270-300nm), Medical Light Therapy (300-320nm), Polymer and Ink Printing (300-365nm), Discrimination (375-395nm), Surface Sterilization/Beauty Sterilization (390-410nm) ).
Environmental Impact - Lower Energy Consumption, Less Waste, and Non-Hazardous Materials
Compared to other alternative technologies, UV LEDs have significant environmental benefits. Compared to fluorescent (CCFL) lamps, UV LEDs consume 70% less energy. In addition, the UV LED has passed ROHS certification and does not contain mercury, a common hazardous substance in CCFL technology.
Ultraviolet LEDs are smaller in size and more durable than CCFLs. Due to the fact that UV LEDs are vibration- and shock-resistant, damage rarely occurs, reducing waste and cost.
Increase life
In the past decade, UV LEDs have been challenged by their lifetime. Despite its many benefits, the use of UV LEDs has decreased significantly because of the ease with which UV beams break down LED epoxy, reducing the lifetime of UV LEDs to less than 5,000 hours.
The next generation of UV LED technology is characterized by a "hardened" or "UV-resistant" epoxy encapsulation, and although it provides a life of 10,000 hours, it is still far from satisfying most applications.
In the past few months, new technologies have solved this engineering challenge. For example, the use of a TO-46 rugged package with a glass lens to replace the epoxy lens, so that it extends the use of at least ten times to 50,000 hours. With this major engineering challenge and the resolution of issues related to the absolute stabilization of a certain wavelength, UV LED technology has become an attractive option for ever-increasing use.
performance
Ultraviolet LEDs also have significant performance advantages over other alternative technologies. Ultraviolet LEDs provide a smaller beam angle and a uniform beam. Because of the inefficiency of UV LEDs, most design engineers are looking for a beam angle that maximizes output power in a target area. For ordinary UV lamps, engineers must rely on using enough light to illuminate the area for uniformity and compactness. For UV LEDs, the lens effect takes into account a more compact radiation angle, allowing most of the UV LED's output power to be concentrated where needed.
To match this performance, other alternatives may require the use of other lenses, thus adding additional cost and space requirements. Since UV LEDs do not require other lenses to obtain a compact beam angle and a uniform beam pattern, with lower power consumption and increased durability, the use cost of the UV LED is less than half that of the CCFL technology.
Cost-effective dedicated options
To establish a UV LED solution for a specific use or to use standard technologies, the former is often more practical in terms of cost and performance. Ultraviolet LEDs are used in arrays in many cases, and the consistency of the beam pattern and light intensity across the entire array is critical. If there is a supplier that provides the entire integrated array needed for a particular application, the total bill of materials will be reduced, the number of suppliers will be reduced, and the array can be tested before being shipped to the design engineer. In this way, the reduction in the number of transactions can save engineering and procurement department costs and provide an efficient program to specifically meet the requirements of the terminal application.
Make sure that the found supplier can provide a cost-effective customized solution, and can specifically design the solution according to your application needs. For example, a supplier with 10 years of experience in PCB design, custom optics, ray tracing and molding will be able to offer a range of options for the most cost-effective and dedicated solutions.
In short, the latest technical improvements of UV LED have solved the problem of absolute stability and greatly extended its lifespan, reaching 50,000 hours. Due to the many advantages of UV LED, such as enhanced durability, non-hazardous materials, low energy consumption, small size, excellent performance, cost savings, cost-effective customization options, etc., this technology is becoming a market, industry, and multiple uses. Attractive option.
In the coming months and years, there will be further improvements, especially in efficiency programs. UV LED usage will grow faster.
The next major challenge for UV LED technology is efficiency. For many applications with wavelengths below 365 nm, such as medical light therapy, water disinfection, and polymer therapy, the output power of the UV LED is only 5%-8% of the input power. When the wavelength is 385 nm and above, the efficiency of the UV LED increases, but only 15% of the input power. As emerging technologies continue to address efficiency issues, more applications will begin using UV LED technology.
