Multi angle understanding of deep UV LED

发布时间:2022-01-26 14:18 来源:萤光创新
At present, there are two major technical products in UV sterilization technology to form an obvious contrast: low pressure UV sterilization mercury lamp products and deep UV LED products.

The service life of low-pressure ultraviolet sterilization mercury lamp is 8000 hours, and the main wavelength is 253.7nm with high sterilization efficiency. Taking single ended 18W as an example, the radiation efficiency is more than 23%, and the high power can reach 30-40%. Moreover, the power of the lamp is from 1W to 300W, which can meet the needs of different use scenarios, and the light maintenance rate is high. Low pressure ultraviolet germicidal mercury lamps are divided into two categories: quartz tube and high boron glass. Quartz tube ultraviolet sterilization lamp is the material with the highest ultraviolet transmission, which can transmit more than 90% of 253.7nm ultraviolet; High ultraviolet intensity, long service life, small light attenuation and good sterilization effect. The service life of the lamp is generally more than 8000 hours. The high boron glass of the high boron tube ultraviolet sterilization lamp can pass through 253.7 nm ultraviolet light, which is only about 50%; Its ultraviolet radiation intensity is small and its service life is short.

The problem of low pressure ultraviolet germicidal mercury lamp is "Mercury". According to the provisions of the Minamata convention formulated by the United Nations Environment Programme, as one of the main parties to the Minamata convention, China has actively implemented the provisions of the Convention and banned mercury in an orderly manner. Therefore, it is imperative to develop new technology products to completely replace the low-pressure ultraviolet sterilization mercury lamp!
 
Deep UV LED products are the best option to replace low-pressure UV sterilization mercury lamp products. Deep UV LED lamp does not contain mercury, which is healthy and environment-friendly. Next, let's talk about deep UV LED from several angles.
Technical aspects
 
The focus of deep UV LED technology is to develop ultraviolet with a wavelength of 260-285nm, which is different from the traditional low-pressure UV sterilization mercury lamp with a wavelength of 253.7nm. Therefore, there are great differences between the two technologies. Deep UV LED has many technical bottlenecks in terms of power, quantity and energy conversion, materials, equipment and cost price. It is urgent for R & D personnel to make further breakthroughs.
Product aspect
 
Deep UV LED is widely used in civil fields such as water purification, air purification, biological detection, sterilization and disinfection, medical devices, polymer solidification, industrial photocatalysis, etc. Moreover, deep UV LED has the advantages of small and portable, environmental protection and safety, easy design, etc. in portable disinfection electronic products such as mother and child sterilizer, elevator handrail sterilizer, lighting and sterilization lamps Sweeping robots and other fields are of great use. In the future, there will be countless creative design products based on mature deep UV LED technology, only unexpected, not impossible.
 
Market aspect
 
Deep UV LED industry chain will form a trillion industry. The deep UV LED industry chain covers different fields such as new materials, precision equipment, chips, packaging, medical application products, consumer electronics, purification products, industrial use products and lighting and sterilization products. Trillion industries are not empty words. It is believed that more enterprises will invest in the deep UV LED industry in the future, and more deep UV LED industrial parks will appear all over the country.
 
To sum up, deep UV LED is an undeveloped "blue ocean", which can be described as "promising"! Whether it is the establishment of theoretical system or the breakthrough of key technology; Whether it is the discovery of new materials or the development of new equipment; Whether it is the establishment of standards or the innovation of market applications... There are large unknown gaps in deep UV LED, which need us to overcome, conquer and use! We believe that with the efforts of all employees in the deep UV LED industry, the deep UV LED will bloom its due dazzling light and bring more wonderful achievements to the Chinese industry!
