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.

The technological advantages of the new generation of UV LEDs
一: a wide range of uses
The spectrum of ultraviolet light contains all wavelengths from 100nm to 400nm 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 sterilizing (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) ).
二: environmental impact - lower energy consumption, reduced waste and non-hazardous materials
Ultraviolet LEDs have significant environmental benefits over other alternative technologies. Ultraviolet LEDs consume 70% less energy than fluorescent (CCFL) lamps. 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.
三: increase life expectancy
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 LED's epoxy, 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.
