While traditional xenon lamp simulators are still dragging down industry efficiency due to "high energy consumption, short lifespan and difficult maintenance", Saifan Optoelectronics has, with its 20 years of accumulation in optoelectronic technology, developed a new generation of LED solar simulators. It not only breaks through the testing bottleneck with "precise replication of natural light", but also relies on its independently developed core LED technology to achieve a triple breakthrough of "low power consumption, long life and easy customization", bringing about a "light testing revolution" to the photovoltaic, aerospace, scientific research, agriculture and other fields, and making green and efficient light technology truly take root in the industry.
Photovoltaic R&D: 650W energy-saving + 10,000-hour lifespan, cost reduction and efficiency improvement visible
Previously, there were eight xenon lamp simulators, with a monthly electricity bill of over 20,000 yuan. The lamps needed to be replaced every six months, and each shutdown for calibration took three days. The maintenance cost alone exceeded 100,000 yuan a year. Wang, the R&D director of a leading photovoltaic enterprise, was once at a loss when faced with the "high cost trap" of traditional equipment. After the introduction of the Saifan LED solar simulator, the changes in cost and efficiency were immediate.
Saifan's LED technology directly addresses the pain points of the industry: By adopting self-packaged high-efficiency LED beads and through the "multi-chip integration + optical lens optimization" technology, the overall power consumption of the machine has been reduced to 650W, which is only 22% of that of traditional xenon lamp equipment. The monthly electricity cost for 8 devices has dropped sharply from 20,000 yuan to 4,500 yuan, saving over 180,000 yuan in electricity costs annually. More importantly, the "longevity gene" of LED: Relying on the "low thermal resistance packaging + intelligent temperature control" technology, the lifespan of the light source can reach up to 10,000 hours. Calculated based on an 8-hour daily usage, there is no need to replace the lamp for three years, completely eliminating the trouble of "stopping work to replace the lamp". Just the cost of replacing the lamp alone can save 48,000 yuan annually.
In terms of the core "accuracy", LED technology also performs astonishingly: the full-band spectral matching degree from 400nm to 1100nm reaches A + level (0.875-1.125), and the near-infrared region restoration accuracy from 780-1100nm exceeds 98%. Equipped with the independently developed "real-time spectral calibration algorithm", the light intensity fluctuation is as low as ±0.3% per hour, and the deviation of continuous 10-hour test data is ≤1%. With the help of the equipment, Wang's team identified the shortcoming of near-infrared absorption in perovskite solar cells within 12 days, increasing the efficiency from 25.1% to 27.3% and shortening the research and development cycle by 60%. "Saifan LED simulator, transforming 'high-cost testing' into 'low-cost and efficient R&D', this is the equipment that photovoltaic enterprises need!" " Engineer Wang sighed.
Aerospace testing: -40℃ weather resistance + LED low-temperature stability, more reliable in replicating space light
"Even a 1% difference in light intensity data during spacecraft battery wing tests could cause a three-year deviation in the in-orbit life assessment." " Sister Li, a test engineer from a certain team in China's aerospace industry, was once worried that traditional xenon lamp equipment "couldn't withstand extreme environments". When simulating the low temperature of -40 ℃ in space, the xenon lamp had unstable gas discharge, with light intensity drift exceeding 5%, making it impossible to verify the weather resistance of the material at all.
Saifan's LED technology provides a perfect answer: It uses military-grade silicon carbide substrate LED beads. Within the temperature range of -40 ℃ to 60℃, the luminous efficiency fluctuates by no more than ±2%. Combined with the 6061-T6 aluminum alloy body and airtight packaging design, the equipment can operate stably for 720 hours without failure in extreme environments. For the space AM0 spectrum (solar radiation without atmospheric filtering), the R&D team, through "training with 200,000 sets of space spectral data", optimized the band ratio of the LED light source, precisely removed atmospheric interference, and the irradiance error was ≤±1%, perfectly regenerating solar radiation in the universe.
In the Mars exploration mission, the Saifan team further demonstrated the "rapid customization ability" of LED technology: It only took 7 days to complete the development of the "Infrared Enhanced LED Module". By increasing the density of LED beads in the 800-1100nm band, the irradiance of this band was raised by 30%, perfectly matching the light characteristics on the Martian surface and helping to increase the power generation efficiency of the Mars rover's solar panels by 22%. LED technology has transformed space light simulation from "barely meeting standards" to "precise and reliable", which is the greatest responsibility for space missions. Sister Li said.
Scientific research agriculture: 1% precision control + low heat generation, more flexible light experiments
In the photocatalytic hydrogen production experiment, for every 1℃ increase in ambient temperature, the activity of the catalyst decreases by 3%. Professor Zhou from Qingdao University of Science and Technology was once troubled by the "high heat generation" of traditional xenon lamp equipment - the surface temperature of the equipment exceeded 70℃ during operation, causing the temperature of the experimental environment to fluctuate by more than 3℃, and the data repeatability was extremely poor.
The "low heat generation advantage" of the Saifan LED simulator has completely solved the problem: by adopting the "distributed heat dissipation + microchannel water cooling" technology, the surface temperature of the equipment during operation is only 38℃, and the environmental temperature fluctuation is ≤±0.5℃, ensuring the stability and reliability of the experimental data. Its "customization" capability is equally outstanding: the ultraviolet (350-400nm), visible (400-760nm), and near-infrared (760-1100nm) bands support 1% precision adjustment, the light intensity can be freely switched from 0.1sun to 2sun, and it can also simulate eight lighting scenarios such as day-night alternations and pulsed light. Professor Zhou's team successfully increased the photocatalytic hydrogen production efficiency by 40% by adjusting the ultraviolet proportion of the LED light source (from 5% to 15%), and the results were published in "Applied Catalysis B: Environmental".
In the agricultural sector, the "low heat generation" of LED is an advantage: In the greenhouse of Lao Yang, a strawberry grower in Shandong, the Saifan LED simulator is hung 30 centimeters above the strawberries, which neither burns the crops nor fails to ensure uniform lighting. With the LED lighting solution of "65% red light + 10% blue light + ultraviolet assistance", the sweetness of strawberries has increased from 8 degrees to 11 degrees, the yield per mu has increased by 150 kilograms, the annual profit has increased by 200,000 yuan, and the electricity cost is 70% lower than that of traditional supplementary lighting. "Before, growing strawberries relied on the weather. Now, with the LED light from Saifan, it's both worry-free and profitable!" " Old Yang said with a smile.
Full-cycle service: 3-year warranty + quick response, more reassuring to use
Saifan Optoelectronics is well aware that good technology requires good service support. In light of the characteristics of LED equipment, Saifan offers a "3-year warranty" service. During this period, if the light source attenuation exceeds 10%, it will be replaced free of charge. Seven major spare parts centers across the country reserve over 95% of commonly used components, providing 7× 24-hour response. Equipment malfunctions can be repaired within 48 hours. A photovoltaic enterprise's production line simulator suddenly experienced a software failure. Saifan engineers provided remote guidance and solved the problem within one hour, without affecting production. For scientific research users, we offer "LED spectral calibration training" to ensure that the team can independently complete daily maintenance and extend the precise service life of the equipment.
Today, Saifan LED solar simulators have served over 200 customers worldwide. The repurchase rate of core customers is 85%, and 80% of new customers choose the LED model due to its "energy-saving and long-lasting" features. From cost reduction and efficiency improvement in photovoltaic research and development to the stability and reliability of aerospace testing, and then to the flexibility and precision of scientific research and agriculture, Saifan has redefined "solar simulation" with LED technology, enabling green light technology to truly empower industrial innovation. If your light testing needs are still plagued by "high energy consumption and short lifespan", the Saifan LED solar simulator is the key to breaking the deadlock for you.
