            Takeaway: growth is slowing in the LED industry development situation, more and more new technology and LED lighting or related industry attention. Graphene, quantum dots, visible light communication... And uv LED. Due to its widespread application, has great market prospect, and become the hot spot in the semiconductor lighting industry in recent years, has quite a few lighting companies in this field both at home and abroad, the following have the data to apply for a patent to see ultraviolet LED industry.

            OFweek semiconductor lighting webex This year, the growth is slowing in the LED industry development situation, more and more new technology and LED lighting or related industry attention. Graphene, quantum dots, visible light communication... And uv LED. Baidu "uv LED", you can find the 152000 results, to a certain extent, indicates that it has received the attention. There is no denying that, however, the application form can be involved in lighting, sterilization, medical, printing, biochemical detection, high density information storage and confidential communications, and many other fields of technology, now at home, give the impression of most people is still confined to the traditional lighting, medical and sterilization, and lack of industrialization application. However, these are only vague impression, mouth says. And want to see the development of a technology really, and how the enterprise layout, most say patent analysis.

            According to the wavelength division, ultraviolet light-emitting diodes (leds) were divided into the UV - ALED (320-410 - nm wavelength), UV - BLED (275-320 nm) and UV - CLED (200-275 nm). UV - ALED mainly used for drying and curing, UV - B for biological sensor, UV - C for sterilization and purification.

            Due to its widespread application, has great market prospect, and become the hot spot in the semiconductor lighting industry in recent years, has quite a few lighting companies in this field both at home and abroad, such as hong optoelec in May, has just released its use of deep uv (UVC) LED effectively restrain bacteria breeding ground for the solution of static water.

            Three stages in China patent layout

            The author "ultraviolet light-emitting diodes (leds) or uv LEDorUVLED" as keywords in the Chinese patent database involving uv LED in China an application for a patent for retrieval, combined the retrieved 5342 pieces of an application for a patent for invention or utility model, retrieve the date as of June 2015. Due to the reasons of the lagging of an application for a patent for public, from 2014 to 2015 patent applications for incomplete statistics.

            Involving the uv LED applications mainly include two categories, category application involves the uv LED chip, including chip preparation and packaging; The different kinds of application form to apply for uv LED.

             

            After a search, found that the patent application number increases year by year, uv LED patent application development trend in China can be roughly divided into three stages. The first phase of 1996-1996, this stage patent applications, patent applications shall not exceed 10 every year, the second phase of 2000-2000, begin to grow, is relatively slow, the third stage since 2008, at an annual rate of hundreds of increase, has maintained rapid growth trend.

             

            All applications to categories of statistics, H01L electrical components in the majority class, second class for F21 lighting, application forms of application in material disinfection, water treatment, currency testing, animal snare and traditional application field in the majority of air purification and so on uv light.

            In the top 20 of the applicant, in the majority with domestic universities and research institutes, including semiconductor research institute of Chinese academy of sciences and Peking about uv LED chips encapsulation, application, and suzhou university, zhejiang university, the institute of spring machine, sichuan university mainly uv LED phosphors in application, such as fudan application below to compare, chips, encapsulation, phosphor and application. In the top 20 of the applicant, the enterprise is less, mainly Japan and Taiwan enterprises, Taiwan enterprises are mainly foxconn's exhibition of crystal and the glory and the energy science and technology, its application for a patent for the main chip packaging and sterilization application, into the domestic enterprises only Jason electronics in Qingdao, the patent application involves the encapsulation and application of ultraviolet chip, mainly the development of ultraviolet disinfection device application, such as drinking water sterilization, toothbrush sterilizer, etc.

            In China an application for a patent for the three characteristics

            As you can see from the above statistics and analysis, involving the uv LED patent application in China presents the following features:

            Uv LED package and application patent layout gradually become mainstream trend from the annual development trend of patent applications, an application for a patent for the uv LED was accompanied by the footsteps of the development of uv LED technology and move forward. Ultraviolet disinfection sterilization has been in the field of medical treatment, air water purification applications, but because of the traditional uv light source of mercury pollution and the size is bigger, problems such as difficult to assembly, on the application of uv light source is not much, 2000 years ago, 2000 years later, LED technology developed, but because the cost is higher, so the application of uv LED began to increase, but relatively slow. 2008 years later, with the development of uv LED technology, reduced costs, especially in the uv LED packaging improvements, about the uv LED application value for people, also with the development is, more and more widely applied, patent applications are increasing quickly.

            Around the traditional application patent layout, fewer researches on the high-end from the patent technology of distribution, in recent years, with uv LED chip, packaging technology research and development, gradually turned to the application of various kinds of application forms and its preparation method. Uv LED application form involves the lighting, the sterilization, medical, printing, biochemical detection, high density information storage and confidential communications and other fields. The application of the current domestic application is mainly in the field of lighting, sterilization, medical and ink printing field, for the biochemical detection, high density information storage and confidential communications research less, unusual applications.

            Technology is focused on the research, the lack of industrialization from the applicant for a patent application type and country distribution, the applicant is given priority to with domestic scientific research institutes, involved chip, encapsulation and various application forms. The Taiwanese companies abroad is involved to chip and encapsulation, application, and in recent years gradually pay attention to the application form to apply for. Chinese enterprises in the area of uv LED to the rapid growth of the patent application started late but mainly involve all kinds of application form to apply for, and the application of uv LED chips encapsulation is not much, mainly has Qingdao desheng electric appliances, lighting enterprise although there are other related application, but they are mainly the ultraviolet LED in the application form to apply for sterilization.

            Purpose: the industrialization is the main focus of the next step

            About the application of uv LED, the comparison of foreign enterprises go ahead, involved area is broad, but domestic enterprises are mainly confined to the traditional lighting, medical and sterilization. Domestic universities and research institutes for uv LED application study is less, and because the uv LED encapsulation life and efficiency problem, there is no optimal solution, is still a focus in the application at home and abroad, in view of this, the author thinks that, in domestic academy continue for uv LED chip, packaging and so on research work at the same time, should also further strengthen the cooperation with enterprises, the development of the application of uv LED, broaden the application area; At the same time, the patent technology into productivity, improve the level of industrialization of research results.

            Uv LED market is wide, the prospect is also tempting, but in the development of technology, seize market, domestic companies also need to do a good job of corresponding intellectual property rights, to build a good foundation. LED patent industry alliance and conduct in-depth cooperation, Beijing university of Chinese academy of sciences, actively promote the industrialization of scientific research institution of uv LED technology transfer, and can help enterprises expand the relevant patent distribution, patent early warning and other services.
