When solar simulation technology steps out of photovoltaic laboratories and precisely controlled spectra become a universal tool for interdisciplinary research, Beijing Saifan Optoelectronics' LED solar simulators are writing new application chapters in fields such as medicine, archaeology, and deep-sea exploration with their multi-scenario adaptation capabilities, making "artificial sunlight" a key force driving multi-disciplinary innovation.
I. Medical and Health Care: The "Light Parameter Library" for Phototherapy Technology Research and Development
In the research of low-intensity laser therapy (LLLT), the Saifan simulator has become an indispensable R&D platform:
Precise light dose control: It can precisely set the light intensity (0.1-500mW/cm²) and irradiation time in the 405nm-980nm band, providing quantitative data for the research and development of phototherapy equipment for wound healing, hair loss treatment, etc. Research from Shanghai Ninth People's Hospital shows that the 660nm red light therapy optimized by this device can increase the healing speed of diabetic foot ulcers by 50%.
Multispectral collaborative research: By simulating the influence of different wavelengths of light on cell activity, it was found that when blue light (470nm) and near-infrared light (810nm) are used in combination, the photothermal killing efficiency of tumor cells is increased by three times, providing a new direction for photodynamic therapy.
Preclinical validation support: We have collaborated with multiple top-tier hospitals to establish a phototherapy research platform. By simulating the light absorption characteristics of human skin and tissues, we optimize the parameter Settings of phototherapy equipment to shorten the transformation cycle from the laboratory to clinical practice.
Ii. Cultural Heritage Protection: The "Light Environment Laboratory" for Cultural Relic Restoration
After the introduction of the Saifan simulator by the Department of Conservation Science and Technology of the Palace Museum, the research on photoaging of cultural relics has entered a new stage:
Simulate the aging process of natural light: By regulating the proportion of ultraviolet, visible and infrared light, accelerate the testing of the fading mechanism of painting and calligraphy pigments and textiles under light exposure, establish a "light exposure duration - pigment stability" correlation model, and provide a scientific basis for the protection of Dunhuang murals.
Low-damage lighting scheme design: For sensitive cultural relics such as bronze wares and lacquerware, the influence of light with different spectral compositions on the surface of the cultural relics was tested, and an LED lighting scheme that can not only meet the display requirements but also minimize damage was designed. It has been applied to the renovation of the Terracotta Army exhibition hall of Emperor Qinshihuang's Mausoleum.
Verification of material restoration effects: In the research on the mounting and unmounting of ancient paintings, the stability of different restoration materials under simulated natural light was tested using a simulator, which helped restorers choose more durable restoration plans and is expected to extend the preservation life of ancient paintings from the Song Dynasty by 200 years.
Iii. Deep Sea and Polar Regions: "Light Adaptation Research in Extreme Environments"
The Institute of Oceanology, Chinese Academy of Sciences, conducts research on the light adaptation mechanism of deep-sea organisms using the Saifan simulator:
Simulate the spectra at different water depths: Precisely reproduce the changes in the solar light spectra at water depths ranging from 0 to 1000 meters (as water depth increases, red light gradually disappears and the proportion of blue light increases), study the evolutionary characteristics of the visual system of deep-sea fish, and discover the existence of special opsins in their retinas.
Polar light cycle simulation: Simulating the alternating light environment of polar day and polar night in Antarctica, studying the relationship between the secretion of melatonin in penguins and the light cycle, and providing physiological rhythm data for polar animal protection.
Underwater photovoltaic equipment testing: Provide light source support for the research and development of photovoltaic power supply systems for deep-sea probes, test the light transmission characteristics in water bodies of different turbidities, optimize the design of underwater solar cells, and increase the equipment's endurance by 300%.
Iv. Industry Empowerment: Building an Interdisciplinary optical Research Ecosystem
Saifan Optoelectronics has launched the "Guanglian Program" to break down disciplinary barriers:
Cross-disciplinary testing and sharing platform: Eight regional sharing centers have been established across the country. Researchers in fields such as healthcare, cultural relics protection, and oceanography can make appointments to use the equipment, lowering the equipment threshold for cross-disciplinary research.
Customized accessory development: Specialized test accessories are developed for specific needs, such as micro-area lighting devices in the field of cultural relics protection and living tissue culture lighting modules in the medical field. 15 utility model patents have been obtained.
Multidisciplinary data sharing library: Integrating test data from different fields to establish a database on the interaction between light and matter, providing data support for interdisciplinary research. Currently, it has collected over 100,000 sets of test data.
From safeguarding the peaceful and quiet times of thousand-year-old cultural relics to exploring the survival wisdom of deep-sea creatures, and then to solving difficult diseases with phototherapy solutions, Saifan LED solar simulators are breaking through the boundaries of traditional applications and becoming a "light hub" of cross-disciplinary innovation. This precisely controllable "artificial sunlight" not only illuminates the small space of the laboratory but also brightens the broad prospects for the integrated development of multiple disciplines.
