Targeting the high-end home appliance market, Guoxing Optoelectronics launches a new high-end series of UVC LED products

Guoxing Optoelectronics Advanced Series UVC LED New Product

Recently, the layout of Guoxing Optoelectronics UVC LED products has made new progress. The Optoelectronics Division is targeting the high-end white home appliance market and has upgraded and launched a high-end series of UVC LED new products, with a sterilization rate of ≥ 99.99%! Compared with conventional products in the market, Guoxing Optoelectronics' advanced series UVC LED further improves optical power and photoelectric conversion rate, with higher light efficiency and more stable product performance. It can be applied to sterilization sectors such as air conditioning, refrigerators, washing machines, etc., providing customers with customizable, safe and efficient technical solutions.

Leading the industry, controlling costs and increasing efficiency

The advanced series UVC LED products of the Optoelectronic Devices Division adopt a new packaging structure and further optimize the process design. Compared with conventional products, the product's optical power can be increased by more than 30%, which is at the leading level in the industry.

Taking the use of a single 100mA UVC LED as an example, the typical optical power value of the product reaches 25mW, and the photoelectric conversion efficiency reaches 4.5%, which is higher than the industry average of 3.5% -4%. In the terminal application process, more than 50% of the lamp beads can be saved, effectively reducing comprehensive costs.

Low temperature environment, efficient sterilization

Although refrigerators can slow down the rate of food spoilage, they still cannot prevent bacterial growth in closed and low-temperature environments. A "household health survey" conducted by the Global Health Council Association in 9 countries including the United States showed that 46% of household refrigerators had excessive bacteria, including Escherichia coli, Salmonella and Listeria.

The Optoelectronic Devices Business Unit collaborates with authoritative testing centers to conduct sterilization verification on the internal environment of refrigerators equipped with advanced series UVC LEDs. The experiment proved that, taking Escherichia coli as a sample, a single 100mW high-order series UVC LED was installed inside the refrigerator, and the sterilization effect could reach 99.99% or more when irradiated for 2h in a low temperature and high humidity environment with a temperature of 2-6 degrees Celsius, effectively ensuring the health and safety of food.

Performance upgrade and comprehensive optimization

Based on leading packaging technology, the high-end series of UVC LED new products have demonstrated outstanding performance in stability, airtightness, reliability, and other aspects:

In HBM mode, the anti-static level reaches Class 3A level, and the electrostatic discharge (ESD) protection ability is strong;

Simulate aging in high temperature and humidity environments, with a light power maintenance rate of over 85% for 500 hours under 60 ℃/90% RH conditions, and the product has good airtightness;

Successfully passed LM80 certification, aged under typical current conditions of 55 ℃, and achieved a power maintenance rate of 90% after 6000 hours, ensuring product reliability;

Compared with traditional mercury lamps, the product has a smaller volume and can be integrated for design, meeting the needs of small volume terminal devices and adapting to multiple scene applications.

Personalized customization and diversified applications

As a pioneer in ultraviolet LED, Guoxing Optoelectronics continues to strengthen its technological advantages, actively tackling the bottleneck technology of deep ultraviolet LED packaging, and developing various specifications of UVC LED products for known effective sterilization bands. Relying on the vertical integration of resource empowerment, the company currently has the ability to design UVC LED solutions and modules for multi-dimensional application scenarios such as household appliances disinfection and sterilization, water treatment disinfection and sterilization, air disinfection and sterilization, mobile disinfection and sterilization, etc. It can provide customized technical solutions for UVC LED with wavelengths of 250-280nm according to customer needs to achieve the best sterilization effect and escort people's healthy life.
