Currently widely used in lighting, display and other visible areas of GaN based blue, green and white LED market competition is fierce, has become a deep red sea". As a result, the market has gradually been considered to be the "blue ocean" ultraviolet (UV) band penetration. UV LED began to gradually replace the traditional UV light source, Yoledevelopment UV LED is expected in 2016 the market size will reach $150 million, share in the traditional UV market will increase from 10.4% in 2011 to 28.1% in 2016.

In the summer of 2015 the LED price war caused the whole industry devastated. In 2015, LED lighting market competition environment of the situation, many LED manufacturers have moved to the UV LED application market. At present, the application of LED UV is very much, involved in the field is also very broad.

那么UV LED究竟可以运用在哪些领域呢？它又有什么样的魔力让越来越多的LED厂商趋之若鹜呢？为此，小编特意对UV LED的用途进行了初步总结，以便大家探个究竟。

So LED UV can be used in what areas? It is what kind of magic so that more and more LED manufacturers rush? To this end, a small series of LED UV specifically for the purpose of a preliminary summary, so that we can find out what.

首先，UV LED在医疗领域可以大展身手

First of all, LED UV in the medical field can show their skills

Inada等用紫外LED（365 nm）对Jurkat肿瘤细胞进行了照射。通过比对，用紫外LED和传统光源系统照射后细胞凋亡和坏死的数量是近似一致的。这证明，紫外LED具有作为光疗用的全新光源的潜力和可能性，可以替代系统笨重、寿命短暂、能耗较大的传统紫外荧光灯。

Inada was irradiated with ultraviolet LED (365 nm) on Jurkat tumor cells. By comparison, the number of apoptosis and necrosis after irradiation with ultraviolet LED and the traditional light source system is approximately consistent. This proves that the UV LED has the potential and possibility as phototherapy with new light source, and can replace the cumbersome system, life is short, high energy consumption of the traditional ultraviolet fluorescent lamp.

其次，UV LED在生物检测领域大放异彩

Secondly, UV LED shine in the field of biological detection

科学家开发出UV LED的荧光检测系统，系统LED模组采用了6个3W的405 nm UV-LED和6个3 W的375 nm UV-LED用于荧光检测，并装有3个白光LED来提供可见图像的一般照明。当BL-ORT被周期30 ms的脉冲UV-LED光激发时，可以获得大部分的完整荧光数据。而且这种脉冲激发光源的能耗可降低至50%。该系统可用于生化反应、安保、工业、农业等领域的荧光检测。

Scientists have developed LED UV fluorescence detection system, system LED module the six 3W 405 nm UV-LED and 6 3 W 375 nm UV-LED for fluorescence detection, and is equipped with three white led to provide a visible image of general lighting. Most of the complete fluorescence data can be obtained when the BL-ORT is excited by a pulse of MS in a period of 30 UV-LED. And the pulse energy consumption of the excitation light source can be reduced to 50%. This system can be used for fluorescence detection of biochemical reaction, security, industry, agriculture and other fields.

再次，UV LED在杀菌消毒领域大显作用

Again, UV LED in the field of sterilization and disinfection effect of Daxian

目前，全球资源匮乏，尤其是以水资源为甚。因此，对于很多水资源匮乏的国家而言水的循环利用具有非常重要的意义。科学研究发现，与单独使用一种UV-LED相比，结合使用UV-A和UV-C两种LED能够更有效地减少废水中微生物的含量，且可以氧化37%的肌酸酐和苯酚，该结果堪比使用诸如TiO2等光催化剂的效果。这种方法能够有效再生利用城市废水。

At present, the global shortage of resources, especially water resources for what. Therefore, to use a lot of water resource scarcity in the country the water cycle is very important. Scientific research found that with the use of a separate a UV-LED compared to using a combination of UV-A and UV-C two led to more effectively reduce the content of microorganisms in wastewater, and 37% of the oxidative muscle anhydride and phenol. The results comparable to use such as TiO2 photocatalyst effect. This method can effectively use the regeneration of city wastewater.

此外，UV LED在化合物降解领域大有前景

In addition, UV LED great prospects in the field of compound degradation

Roddick等研究了255 nm UV-LED与H2O2结合的间歇式反应器对于处理高盐的城市污水中的反渗透浓缩物的效果。以溶解有机碳（DOC）浓度、颜色以及酸碱度（pH值）作为检测指标。研究结果表明UV-LED在反渗透浓缩物降解处理领域具有潜在的应用前景。

Roddick of 255 nm UV-LED combined with H2O2 batch reactor for treatment of high salt city sewage in the reverse osmosis concentrate effect. The dissolved organic carbon (DOC) concentration, color and pH value (pH value) as the detection index. The results show that the UV-LED in the field of reverse osmosis concentrate degradation treatment has a potential application prospect.

另外，UV LED在印刷光刻领域大有可为

In addition, UV LED have a brilliant future in the printing field of lithography

紫外固化是目前UV-LED应用产业的主要方向之一。博林格林州立大学研究组比较了UV-LED与传统UV光源用于丙烯酸酯固化的效果，研究了两者的聚合速率以及生成的涂层性能，证实了UV-LED可以替代传统UV光源用于各种固化应用领域。

UV curing is one of the main direction of UV-LED industry application. Bowling Green State University study group compared with the UV-LED and traditional UV light source is used for curing acrylate effect of both the polymerization rate and formation of the coating properties, confirmed that the UV-LED can replace the traditional UV light source for various curing applications.

最后，UV LED在光通信大有作为

Finally, UV LED in optical communication way

紫外光通信作为一种新的通信手段，其最突出的优点是不易被探测和截收，可以通过散射进行非视线通信，非常适用于近距离抗干扰和有遮挡的通信环境。

Ultraviolet communication as a new means of communication, and its most prominent advantage is not easy to detect and intercept and non line of sight communication can be carried out by scattering, is very suitable for close range anti interference and obstruction of communication environment.

UV LED发展渐趋商业化，其应用领域也成为LED厂商争相布局的对象。那么UV LED目前为止发展局面又是怎样的呢？

UV LED is a commercial development, its application field has become the object of LED manufacturers competing layout. Then the UV LED far development situation and how is it?

目前为止，受限于紫外LED技术水平，生产厂商并不多，大体可分四个层次。行业普遍认为UV-B和UV-C全世界做得最好的是美国的SETi，雄霸深紫外LED性能宝座已经超过10年；其次是韩国的LGIT和首尔半导体；另外是美国的Lumileds和德国的Osram；中国涉足紫外LED领域的厂商已归结为第四层面，主要是台湾公司，包括光宏、联胜、旭明等等，以及大陆晶瑞光电和青岛杰生。其中，美国、日本、韩国企业占UV LED主导地位

Now, due to the UV LED technical level, the manufacturer is not much, generally can be divided into four levels. Industry generally believe that the UV-B and UV-C the best in the world is the United States SETi, dominated the performance of deep UV LED throne has more than 10 years; followed by South Korea's LGIT and Seoul semiconductor; also is the United States Lumileds and Germany OSRAM; China involved in the field of UV LED manufacturers have already returned to the fourth level, mainly Taiwanese companies, including light macro, Lian Sheng, Xuming and so on, and, Jing Rui optoelectronics and Qingdao Jason. Among them, the United States, Japan, South Korea UV LED enterprises accounted for the dominant position

由于技术难度大，许多欲进入这一领域的企业望而却步，紫外LED在我国市场也尚未完全打开，伴随着LED市场的日渐饱和，企业想在LED市场有所斩获，除了要有远见卓识以外，更需有过硬的技术作为支撑。

Due to the technical difficulty, many want to enter the field of enterprises prohibitive, UV LED in the Chinese market has not yet fully open, with LED market increasingly saturated, the enterprise wants to in the LED market gains, in addition to vision, more need to have excellent technology for support.

UV LED作为当前最炙手可热的技术之一，可以说谁能预先攻破其技术难关，谁将能在该领域掌握话语权。那么，全球UV LED技术专利是呈现怎样的分布情况呢？

UV LED is one of the most sought after technology, can say who would have to break the technical difficulties in the field, who will be able to master the right to speak. Then, the global UV LED technology patent is presented the distribution of what?

根据LED产业专利联盟发布的《紫外LED专利技术分析报告--外延芯片、封装器件篇》显示，从专利区域构成上来看，近200 份有关紫外LED 外延、芯片和器件封装领域的相关专利中，专利数量最多的是中国地区，约占总数的56%；其次是美国地区，台湾和日本，韩国在这一领域也具有相当的优势。

According to LED industry patent alliance released of the UV LED patent technology analysis report, epitaxial chip and package device "shows, from the point of view of regional patent composition, nearly 200 copies of the UV LED epitaxy, chip and device packaging field related patent, patent number most is China, accounted for 56%; followed by the United States, Taiwan and Japan, South Korea in the field also has a considerable advantage.

Although China's LED UV patent number occupies an absolute leading edge, but the current Chinese UV-LED companies have not mastered the core technology, especially in the field of chip, epitaxy and device packaging. Therefore, China's LED UV industry is still in the early stages of development.

虽然，整个UV LED市场规模并不大，且由于UV LED芯片核心技术难点造成产品价格颇为昂贵，但随着LED照明利润越来越低，加之2016年LED价格战或持续升温，UV LED的几大应用成新蓝海，发展可期。

Although the UV LED market scale is not large, and due to the UV LED chip core technical difficulties caused the product price is quite expensive, but with LED lighting profits become lower and lower, in addition to 2016 led price war or continue to heat up, application of UV LED into a new blue ocean, the development period.
