The world's top Ten innovative LED light source devices in 2020 (1/6)
Since the birth of the LED light source, the lighting industry has undergone rounds of technological changes, bringing different lighting control modes, different energy saving methods, and different photobiological characteristics to lighting users...Although LED light source technology innovation The benefits brought by the people are enough to make the majority of lighting research workers proud, but the research and development personnel of major scientific research institutions, enterprises and institutions around the world have not stopped the LED light source technology to continue to innovate.
Below, China Lighting Network, through the display and interpretation of the world's top ten innovative LED light source devices in 2020, looks forward to bringing important lessons for the lighting industry in product development and innovation.
1. Metal halide perovskite LED
In June, a joint team of researchers from the German HZB Research Center and the Humboldt University of Berlin (HU) successfully produced a metal halide perovskite functional light-emitting diode printed from a semiconductor compound solution.
In the preparation process of the LED light source device, the researchers used a salt crystal attached to the substrate and triggered the formation of the grid of the subsequent perovskite layer as an attractant or catalyst to make the salt sample printed on the substrate The body crystallizes quickly and uniformly, which overcomes the difficulty of producing high-quality LED semiconductor layers from liquid solutions in the past, and creates a higher luminosity and better electrical performance than the previous use of additive manufacturing processes. Printed LED.
Through the inkjet printing preparation process of HZB and HU researchers, the produced metal halide perovskite LED is expected to produce particularly high luminous efficiency, improve the light quality of lighting products, and at the same time be a higher luminous efficiency LED light source in the future. The birth of electronic components provides technical reference.
