In such a hot trend, in the last year, the global lighting industry has another batch of scientific and technological innovation achievements, constantly enhancing the universal value of lighting in the development of The Times.
Below, China Lighting network by showing the world's top ten lighting technology in the last year or so, singing the praises of innovation and development of global lighting industry.
1. UVC-LED package disinfector
In August 2021, the UVC-LED logistics package sterilizer, independently designed and developed by Shanxi Zhongke UV-Electric Technology Co., LTD., was put into use in Xinkaiyue Logistics Park, Changzhi City, Shanxi Province, China. Within 6 seconds, the machine can complete the elimination of logistics packages.
As the world's first deep ULTRAVIOLET LED package disinfection machine applied to the postal express industry, the machine uses a new ultraviolet light source -- deep ULTRAVIOLET LED as the disinfection factor light source, in the package disinfection machine is covered with about 5000 deep ULTRAVIOLET LED chips, the package up and down, front and rear, left and right sides are exposed to high doses of ULTRAVIOLET light. It can effectively kill all kinds of bacteria and viruses carried on the surface of the package.
The UVC-LED Logistics parcel sterilizer has a significant "second kill" effect on COVID-19novel Coronavirus as tested by an authoritative third-party testing institution. In addition to playing an important role in sterilization and disinfection in the postal express industry, the machine can also be used in airports, railway stations, parcel transportation, baggage security and other aspects of sterilization and disinfection purposes as well as hospitals and other places of object surface sterilization.
2. OLED tattoos for health monitoring
In March 2021, a team of researchers from University College London (UCL) and the Italian Institute of Technology (ITL) used advanced OLED technology to produce a world-first "tattoo" that can be used to monitor different indicators of human body performance and even check the freshness of fruits and vegetables. When the job is done, the tattoo can be washed off with soap.
Researchers from the two universities have developed an electroluminescent polymer just 76 nanometers thick, using the same luminescence technology used in televisions and smartphones today. The polymer emits light whenever it is subjected to an electric field. As long as the "tattoo" can be placed between a pair of electrodes protected by an insulating layer, it can be combined with a variety of electronic products to achieve a wide range of biological monitoring applications.
In the future, the tattoo will also feature real-time data notifications, a tiny power source and a range of protective features that won't degrade in the air.

In April 2021, scientists at the University of South Carolina developed the world's smallest and brightest deep ULTRAVIOLET LED light source, promoting UVC leds to better compete with mercury lamps in applications requiring high doses of deep ULTRAVIOLET irradiation.
The light source chip is only 5 microns in size and has a wavelength of 281nm. The UVC LED array composed of these chips has a brightness of 361W·cm-2. Thanks to the superior heat removal technology to eliminate thermal droop, the output power of the 324 pixel arrays with a diameter of 5 microns is increased by more than 5 times in continuous wave mode and by more than 15 times in pulse mode compared to a single chip reference.
Since the external quantum efficiency of the linked micropixel array does not decrease with the reduction of pixel size, it is possible to produce a smaller size of DEEP ULTRAVIOLET LED without affecting device performance in the future, thus reducing the application of mercury lamp in the field of public mask disinfection, and further reducing social concerns about mercury toxicity.
