The 12th Summit Forum | Hongli Photoelectric Qiao Wei: Deep UV Encapsulation Opens LED Application New “Blue Ocean”

[Text|High -tech LED reporter Yue Mengdi] In the past two years, the application of domestic UV LED (UV-LED) technology has developed relatively rapidly. Currently, deep ultraviolet LED (UV LED) is mainly used in biomedical, anti-counterfeiting identification, purification (water, air, etc.) Areas, computer data storage, and military. However, with the development of technology, new applications will continue to appear to replace the original technology and products. UV LED has broad market application prospects.

Different wavelengths of UV devices have very different uses, and different power functions are different in the same band. 200-280nm for water, air and surface disinfection, biopharmaceutical and DNA sensing; 280-315nm for photomedicine, protein analysis, drug detection; 315-400nm for UV curing, anti-counterfeiting technology, sunbathing, lithography , photocatalysis, etc.

On the afternoon of September 26, at the 12th meeting of the C-level floor of the B-zone of Guangzhou Pazhou Canton Fair, the 12th Gaogong LED Industry Summit Forum hosted by Gaogong LED, Qiao Wei, senior project leader of Hongli Optoelectronics, presented to the present Sharing the development of Hongli's deep UV packaging.

Compared to the more mercury lamps currently used on the market, UV LEDs have many advantages. First, UV LED sterilization can control the band freely, unlike the mercury-based lamp, which has more spectrum peaks than the full-band spectrum. Second, the light intensity per unit area of ​​the UV LED is more than 1000 times higher than that of the mercury lamp, but the same light output. The energy consumption is only 1/10 of the mercury lamp; third, the ultraviolet LED is not affected by the chemical equilibrium conditions such as temperature, concentration and activity; fourthly, the process of sterilization is non-toxic, no residue, no odor; fifth, sterilization The principle is to destroy the structure of the life center DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) of viruses and bacteria, so that they can die immediately or lose their ability to reproduce. They do not need to change drugs or use combination drugs, especially for air, water and objects. Surface disinfection.

"The role of a DUV LED is much higher than your imagination." Qiao Wei told everyone that DUV LEDs have the lowest energy consumption and the best sterilization effect. At the same time, he also mentioned that the future development of Hongli Optoelectronics' DUV LED package is mainly to take the road of customization. “The traditional sales model has been changed, saving customers time and being the first to enter the new blue ocean.”

The technical threshold of UV is relatively high. The main reason is that the ultraviolet band is relatively short, and it is very difficult to make the optical power, stability and life index of the chip very difficult.

At the 12th High-tech Summit Forum, Qiao Wei, senior project leader of Hongli Optoelectronics, brought the latest achievements of UV packaging after the strategic cooperation between Hongli Optoelectronics and Qingdao Jiesheng, and discussed with the peers how to open LEDs in deep ultraviolet packaging. Apply the new "Blue Ocean".

Unlike Blu-ray, UV LEDs are currently in the process of technological development, with fewer restrictions on patents and intellectual property rights, which is conducive to occupation and leading the future technological commanding heights.

600W Foldable LED Grow Light:

The light souce has Red, Blue lights. Blue wavelength promote the boots grow, leafy fast, Red promote blooming, flowering and fruiting.Our led plant grow light is full spectrum light,can meet all the light and wavelength all the plants needs at any phases.


Our folding design make the lamp can be large size but also smaller size when folding.180 degress adjust design can make the packaging only 1/2 as extended.It helps protect the light source and make transportation easier.


To match some customer's special requirement,we OEM&ODM LED Grow Light Dimmable and LED Grow Light with Timer.
