The technology advantage of UV led (ultraviolet ray led）
Although the ultraviolet ray is potentially dangerous to biological in our daily life，but ultraviolet will provide many beneficial effects in many fields. As standard visible LED ultraviolet LED development will bring more convenience to many different applications. The latest technology developments are parts of the uv LED market expands to product innovation and performance. Design engineers are noted, compared to other alternative technologies, ultraviolet LED technology can produce huge profits, energy and space savings. The next generation of UV LED technology has 3 important advantages, which is the reason that the technology market in the next five years is expected to grow 31%.
1. widely range of uses
UV spectra contain all lengths of 100nm to 400nm wavelength,generally divided into three categories:UV-A (315-400 nm, also known as uva rays), UV - B (280-315 nm, also known as the uvb rays),UV-C (100-280 nm, also called UVC).
The early uv led of application are Dental instruments and forgeries, but the performance, cost and benefits of durability and extend lifeworking, which is making a rapid increase in the use of UV LED. Application of UV LED include: optical sensors and instruments (230-400nm), UV authentication, barcode (230-280nm), surface water sterilization (240-280nm), identification and detection and analysis of body fluids (250-405nm), protein analysis and drug discovery (270-300nm), medical light therapy (300-320nm), polymers and inks (300-365nm), forgeries (375-395nm), surface sterilization / Beauty sterilization (390-410nm ).
2. The environmental impact - lower energy consumption, reduce waste and non-hazardous materials
Compared to other alternative technologies, ultraviolet LED having significant environmental benefits. Compared with fluorescent (CCFL) lamps, UV LED energy consumption 70% lower. In addition, UV LED passed ROHS certification, excluding CCFL technology common mercury harmful substances. UV LED size is small and durable than CCFL. Since the ultraviolet LED having the role of anti-vibration and impact, little breakage, thereby reducing the costs of waste and cost.
3. Increased life expectancy
In the past decade, ultraviolet LED has challenged aspects of the subject to life. Although it has many advantages, but the utilization of an ultraviolet LED decreased significantly, it is easy to break down because the ultraviolet beam epoxy LED, an ultraviolet LED of which will reduce the life of 8 to less than one thousand hours. UV LED's next-generation technology to "harden" or "UV" epoxy package is characterized, although life provided will reach 20,000 hours, but still far failed to meet most applications.
