Mercury free, nontoxic and highly efficient sterilization of uvc-led
In 2000, the U.S. Food and Drug Administration approved ultraviolet (UV) disinfection as an effective disinfection method to inactivate pathogens and spoilage microorganisms in food, water and beverages.

According to the report of the US Environmental Protection Agency, ultraviolet disinfection has been carried outIt is recommended as a substitute for chemical additives in surface water treatment.

With the development of the times, uvc-led is more and more used in various fields, and gradually replace the mercury lamp which is easy to break, inconvenient to use and toxic.

Light output efficiency of uvc-led bothering application end

WPE(wall-plug efficiency)——
UV-LED luminous efficiency: also known as external quantum efficiency, equal to the product of internal quantum efficiency and extraction efficiency. Internal quantum efficiency, also known as electro-optic conversion efficiency, is related to impurities, energy bands, defects in device materials, and barrier layer in device structure. Extraction efficiency refers to the quantity of photons released from the inside of the device to the outside and can be calculated. At the present level, the removal efficiency of deep UV devices is the key to improve the optical efficiency.

For a long time,The luminous efficiency of UVC products on the market is low, only 2 ~ 3%, leading toShort sterilization distanceIn order to achieve the killing effect required by usersHigher arrangement density of lamp beadswait.


Because of this defect, the effect of integrating it into the sterilization equipment is often not ideal, and the application end needs to compromise according to the energy efficiency of the UVC product,At the expense of a certain user experience and market space, the problem is left to the manufacturers。

The output efficiency of UVC is closely related to the epitaxy, chip and package level. With excellent R & D conditions and years of experience in deep UV field, deep UV technology has been completed in the near futureBreakthrough of UVC luminous efficiency！


Relative market average WPE & nbsp（ Wall plug efficiency is only 2-3%The average WPE of deep purple UVC is more than 5%，More than doubled, which can be easily realized 12mW@40mA 、 30mW@100mA 、 100mW@350mA The output of UVC optical power is about 1.

Mass production has been achieved! Fast delivery

The shortage of UVC has been puzzling the market in 2020. The new uvc-led of dark purple has realized the rapid production of its own production line, which can provide the majority of manufacturers with fast supply, quality and quantity.
