"11 years without the need to replace lights, electricity bills saved by 70%, test data recognized by TUV!" " This is the genuine exclamation of a certain photovoltaic enterprise after introducing the Saifan LED solar simulator. While traditional xenon lamp equipment is still trapped in the industry pain points of "short lifespan, high consumption and insufficient precision", the LED solar simulator developed by Saifan Optoelectronics with 20 years of technological accumulation has achieved three major breakthroughs: "100,000-hour light source lifespan, full-band coverage from 280nm to 1800nm, and ±0.5% precision control". Become the "light testing infrastructure" in fields such as photovoltaic, aerospace, automobiles, and hydrogen energy, achieving a true unity of precision and energy conservation.
Photovoltaic R&D: From "Data Distortion" to "0.3% Deviation", Dual breakthroughs in Efficiency and cost
Previously, when using xenon lamps to test perovskite batteries, the morning data was 26%, but it dropped to 24.5% in the afternoon. Half a year was spent on verifying the data. The cost of replacing the lamps is 50,000 yuan per year, and the monthly electricity bill for the 8 devices exceeds 20,000 yuan. The predicament of Mr. Zhang, the R&D director of a certain TOPCon battery enterprise, was once a common pain point in the photovoltaic industry. After the introduction of the Saifan LED solar simulator, the R&D and cost logic was completely rewritten.
Saifan's LED technology directly addresses the core contradiction: It adopts A 128-channel LED light source matrix independently packaged, combined with the 5th generation intelligent spectral fitting algorithm. The full-band spectral matching degree from 400nm to 1100nm reaches A + level (0.875-1.125), and the restoration accuracy in the near-infrared region from 780-1100nm exceeds 98%. The 420nm blue light response data deviates from natural light by only 0.3%. More importantly, it has a "longevity gene" : the light source has a lifespan of up to 100,000 hours. Calculated based on an 8-hour daily usage, it can operate continuously for 11 years, almost never requiring replacement throughout its lifetime, completely eliminating the trouble of "changing the lamp every six months". The power consumption of the 650W entire machine is only 22% of that of traditional xenon lamps. The monthly electricity cost for 8 units of equipment has dropped from 20,000 yuan to 4,500 yuan, and the annual electricity cost savings for a 1GW production line exceed 200,000 yuan.
"With Saifan, the test deviation of the same batch of batteries has been reduced from ±0.8% to ±0.3%, and there have been no more grading errors." " The team led by Engineer Zhang, with the help of the device's millisecond-level response module (with a response speed of 10μs), captured the interface charge trap repair mechanism of perovskite materials, enabling the battery life to exceed 1,500 hours. The results were published in Nature Photonics. In the mass production stage, the equipment is integrated with the MES system, increasing the A-grade product rate from 88% to 93% and reducing defective product losses by 12 million yuan annually.
Aerospace and Automotive: Extreme Adaptability + Rapid customization, covering all lighting requirements in various scenarios
For spacecraft battery wing tests, if the light intensity drift exceeds 5% at a low temperature of -40℃, it is considered a scrapping data. The photovoltaic panels on the roof of new energy vehicles must withstand the dual tests of the high temperatures in the Sahara and the strong ultraviolet rays in Northern Europe. The words of Engineer Li from the Beijing Institute of Aerospace Metrology reveal the strictness of extreme environment testing. The "all-scenario adaptability" of the Saifan LED simulator provides the perfect answer.
For the aerospace field, the equipment adopts the 6061-T6 military-grade body and airtight packaging, operating stably within the temperature range of -40 ℃ to 60℃. The 720-hour low-temperature irradiation test shows a light intensity fluctuation of no more than ±1.2%, accurately reproducing the AM0 space spectrum and helping to extend the lifespan of spacecraft coatings by three times. During the Mars exploration mission, the Saifan team completed the development of the "AM0 + Infrared Enhancement" module in just seven days, increasing the irradiance in the 800-1100nm band by 30% and boosting the efficiency of the Mars rover's sails by 22%.
In the field of automotive testing, a certain automaker used its simulation of the extreme light combination of "Sahara Desert + Nordic Aurora" to conduct accelerated aging tests on automotive-grade photovoltaic roofs. After improving the process, the product's lifespan was extended from 5 years to 8 years. This customization capability stems from modular design - it supports full-band adjustment from 280nm to 1800nm, and can quickly add deep ultraviolet and far-infrared modules. It once completed the 200-300nm deep ultraviolet transformation for a certain photocatalytic enterprise within 48 hours, filling the domestic technological gap.
Scientific Research and Agriculture: Precise Regulation + Scene Simulation, Unlocking New Possibilities of Light Applications
"Photocatalytic hydrogen production requires precise control of the proportion of ultraviolet light. Strawberry cultivation needs to simulate the strong light at high altitudes, which traditional equipment simply cannot achieve." " Professor Zhou from Qingdao University of Science and Technology's problem was completely solved by the "Light Color Palette" function of Saifan.
The device supports 1% precision adjustment in the ultraviolet (300-400nm), visible and near-infrared bands. The light intensity can be continuously switched from 1W/m² (weak light) to 1500W/m² (strong light), and it can also simulate 8 scenarios such as day and night alternations and pulsed light. Professor Zhou's team increased the photocatalytic hydrogen production rate by 27% by means of the ultraviolet enhancement mode, reducing the cost of green hydrogen to 35 yuan per kilogram, reaching the commercialization threshold. The flower base in Yunnan used it to simulate the "strong ultraviolet + high infrared" spectrum of the plateau, increasing the anthocyanin content of roses by 22% and extending the vase life by 5 days. The cucumber base in Shandong adopts a 7:3 ratio of red and blue light, increasing the yield by 25%.
"Previously, students would rush to conduct experiments during the low-temperature period. Now, they can obtain stable data at any time, and the research progress has been accelerated by 50%." " The low heat generation advantage mentioned by Professor Zhou stems from the distributed heat dissipation technology of the equipment. During operation, the surface temperature is only 38℃, and the environmental fluctuation is ≤±0.5℃, ensuring the reliability of the experimental data.
Full-cycle service: From "Equipment Sales" to "Value Partner"
Saifan is well aware that high-end equipment requires professional services as a foundation. Its "Guangxiang Service" system covers the entire life cycle: The 7 major spare parts centers across the country ensure that the fault response time is ≤2 hours, the average repair time is only 4 hours, and the urgent calibration needs of a certain testing institution are resolved within 12 hours. Offer "one-on-one" spectral calibration training to help research teams master the core operations within a week. The equipment has passed international certifications such as IEC 60904-9 and JIS C 8912. The test data has been recognized by German TUV, helping enterprises go global to the European Union and increasing the export volume by 42%.
Today, Saifan LED solar simulators have helped over 20 achievements be published in SCI journals, served more than 200 customers worldwide, and achieved a core repurchase rate of 85%. From the efficiency revolution of photovoltaic production lines to the energy guarantee for Mars exploration, and then to the harvest code in the fields, this "precise light that doesn't need to be replaced for 11 years" is becoming the "light engine" for innovation in various industries with its value of "affordable, usable and good".
