Professor Li from an institute under the Chinese Academy of Sciences once struggled with the lighting problem of a 150㎡ photocatalysis pilot plant: "The traditional xenon lamp supplementary lighting equipment required 30 units to be connected, resulting in an insufficient uniformity of 60%, and the experimental data from the same batch deviated by more than 20%. For three years, no top journal papers were produced. Moreover, the ultraviolet wavelength energy of the xenon lamp was not adjustable, making it unable to match the requirements of different catalytic reactions, and the industrialization process of the project was repeatedly postponed."
The Sefa Research Customized 3A Level LED Steady-State Simulator injects core power into scientific research breakthroughs. The equipment adopts a "high-power LED array + distributed light uniformity design", and a single unit can cover a 150㎡ pilot plant, with a light uniformity of 96%, and the parallelism of experimental data has been improved from 60% to 95%, completely solving the problem of data dispersion. It supports independent adjustment of 1% accuracy in the ultraviolet, visible, and near-infrared wavelength bands, and can customize the spectral curve to precisely simulate the catalytic efficiency under different lighting conditions, perfectly adapting to various scientific research scenarios such as photocatalysis and perovskite.
"The experimental deviation was reduced from 20% to 1.5%. In the past year, we published 4 top-tier papers, applied for 5 national patents, and successfully achieved industrialization of the project." Professor Li praised the intelligent interlocking capability of the equipment. "Through the upper computer software, the light intensity gradient and spectral combination can be preset, and the temperature, humidity, and pressure sensors can be linked to achieve closed-loop control. Previously, experiments required 5 people to operate, but now one person can complete it. The annual electricity cost has decreased from 180,000 yuan to 25,000 yuan. The maintenance workload has been reduced by 80%, and the frequent replacement of lamps and repeated calibration problems have been completely eliminated."
