Although ultraviolet light is potentially dangerous to living things in daily life, such as sunburn, ultraviolet light can provide many beneficial effects in various fields. Like 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 new heights in product innovation and performance. Design engineers are noticing that the new technology of UV LEDs can generate significant profit, energy and space savings compared to other alternative technologies. The next generation of UV LED technology has five important advantages, which is why the technology market is expected to grow by 31% in the next five years.
Wide range of uses
The spectrum of ultraviolet light contains all wavelengths from 100 nm to 400 nm and is generally subdivided into three categories: UV-A (315-400 nm, also known as long-wave UV) and 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 identification applications are early applications of UV LEDs, but performance, cost and durability benefits, as well as extended product life, are rapidly increasing the use of UV LEDs. Current uses for UV LEDs include: optical sensors and instruments (230-400 nm), UV identification, barcode (230-280 nm), surface water sterilization (240-280 nm), identification and body fluid detection and analysis (250-405 nm), Protein analysis and drug discovery (270-300nm), medical phototherapy (300-320nm), polymer and ink printing (300-365nm), identification (375-395nm), surface sterilization / cosmetic sterilization (390-410nm ).
Environmental impact - lower energy consumption, reduced waste and non-hazardous materials
Ultraviolet LEDs have significant environmental benefits over other alternative technologies. Compared to fluorescent (CCFL) lamps, UV LEDs consume 70% less energy. In addition, UV LEDs are ROHS certified and do not contain mercury, a hazardous substance commonly found in CCFL technology.
Ultraviolet LEDs are smaller and more durable than CCFLs. Since the ultraviolet LED has anti-vibration and impact resistance, it is rarely damaged, thereby reducing waste and cost.
Increase life
In the past decade, UV LEDs have been challenged by their longevity. Despite its many benefits, the use of UV LEDs has dropped significantly because the UV beam easily decomposes the epoxy of the LED, reducing the lifetime of the UV LED to less than 5,000 hours.
The next-generation technology for UV LEDs is characterized by a “hardened†or “UV-resistant†epoxy package that, while providing a lifetime of 10,000 hours, is far from being able to meet most applications.
In the past few months, new technologies have solved this engineering challenge. For example, the use of a TO-46 sturdy package with a glass lens replaces the epoxy lens, which extends its use time by 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 growing use.
The next major challenge in UV LED technology is efficiency. For many applications with wavelengths below 365 nm, such as medical phototherapy, water disinfection and polymer therapy, the output power of UV LEDs is only 5%-8% of the input power. When the wavelength is 385 nm and above, the efficiency of the UV LEDs Improve, but only 15% of the input power. As the emerging technologies continue to address efficiency issues, more applications will begin to adopt UV LED technology.
performance
Ultraviolet LEDs also have significant performance advantages over other alternative technologies. Ultraviolet LEDs provide a small beam angle and a uniform beam. Due to the low efficiency of UV LEDs, most design engineers are looking for a beam angle that maximizes output power in a certain 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 action allows for a more compact radiation angle, allowing most of the output power of the UV LED to be concentrated where needed.
To match this performance, other optional techniques may require the use of additional lenses, thus adding additional cost and space requirements. Because UV LEDs do not require additional lenses to achieve a compact beam angle and uniform beam pattern, with lower energy consumption and increased durability, UV LEDs are used in less than half the cost of CCFL technology.
Cost-effective, dedicated choice
The establishment of UV LED solutions for a specific application or the use of standard technologies, the former is often more practical in terms of both cost and performance. Ultraviolet LEDs are used in arrays in many cases, and the consistency of beam patterns and light intensity across the array is critical. If there is a supplier that provides the entire integrated array for a particular application, the total price of the bill of materials will decrease, the number of suppliers will decrease, 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 the cost of the engineering and procurement department, and provide an efficient solution to specifically meet the requirements of the terminal application.
Ensuring that suppliers are found to offer cost-effective, customized solutions that can be tailored to your application needs. For example, a supplier with decades 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 technological improvements in UV LEDs have solved the problem of absolute stabilization and greatly extended their lifespan to 50,000 hours. Due to the many advantages of UV LEDs, such as enhanced durability, non-hazardous materials, low energy consumption, small size, excellent performance, cost savings, and cost-effective customization options, the technology is becoming a market, industry and multiple uses. An attractive option.
In the coming months and years, there will be further improvements, especially in the efficiency program. The use of UV LEDs will grow even faster.
