"Giant photovoltaic module certification, segmented test splicing error exceeded 8%, TUV certification was repeatedly rejected" "At 60℃ high temperature, LED equipment light attenuation was 15%, spacecraft whole plate material aging test was forced to be interrupted" "Strong ultraviolet photocatalytic pilot test, traditional equipment insufficient ultraviolet energy The reaction efficiency deviation of 28% - In harsh scenarios such as international certification of super-large components, extreme environment material testing, and strong ultraviolet research, the pain points of "insufficient area, incomplete full-spectrum coverage, and poor anti-fabrication" have once plunged countless enterprises and research institutions into the predicament of "data failure, project delay, and soaring costs".
Saifan Optoelectronics has been deeply engaged in optoelectronic technology for 20 years and has launched the 7IS series of ultra-large radiation 3A-level xenon lamp steady-state solar simulators with three core advantages: "3.2m×5.0m ultra-large radiation coverage + full compliance with IEC 60904-9 3A-level indicators + core xenon lamp steady-state technology" It is perfectly adapted to the strict testing requirements in large areas, strong irradiation and extreme environments. Today, this "lighting giant" has served over 250 high-end customers worldwide, increasing the certification efficiency of giant photovoltaic modules by five times, achieving a 100% pass rate in extreme environment material tests, and having a parallelism of over 96% in strong ultraviolet scientific research experiments. It has become the "hardcore choice" for strict lighting tests.
1. International Certification for Giant Photovoltaic Modules: 3.2m×5.0m super-large radiation area, 3A precision, pass TUV certification in one go
Mr. Wang, the certification director of a multinational photovoltaic enterprise, was once extremely troubled by the certification of giant modules. We developed a super-large photovoltaic module of 3.2m×5.0m. The traditional small spot simulator had to test it in 16 segments, which took three days. Not only did the total error after assembly reach 8%, but it was directly rejected when sent to TUV Rheinland for certification. The plan to enter the European market was delayed by six months. More importantly, mainstream markets such as Europe and Australia explicitly require the use of xenon lamp simulators for testing (the spectrum of xenon lamps is closer to natural sunlight, and the data recognition is higher), while traditional xenon lamp equipment has a small area and poor stability, which simply cannot meet the demands.
After the introduction of the Saifan 7IS series ultra-large aperture 3A-level xenon lamp steady-state simulator, the certification problem was easily solved. The core highlight of this device is the 3.2m×5.0m super-large coverage area - no need for segmentation, it can cover the entire board of giant components at one time. The testing time has been compressed from 72 hours to 14 hours, the efficiency has been increased by 5 times, and the certification cost of a single component has been reduced by 65%. Even more hardcore is achieving 3A-level compliance in all indicators: The spectral matching degree is A + grade (0.875-1.125), the light intensity uniformity is A grade (≤±3%), and the time stability is A grade (≤±0.2%/h). It fully meets the international certification standards such as IEC 60904-9, TUV, UL, and IEC. "Now, sample submission and certification can be passed in one go." International testing institutions all recognize the data of the 7IS series. The products have smoothly entered the markets of Europe, Australia and Southeast Asia, with an annual additional revenue of over 300 million yuan.
The strong core advantages of xenon lamps are fully demonstrated: The 7IS series adopts imported 1800W ultra-high pressure short-arc xenon lamps, continuously covering the entire wavelength range from 300nm to 1100nm. Especially in the 280-400nm ultraviolet band, the energy restoration accuracy exceeds 97%, far superior to LED devices, perfectly simulating the full-spectrum characteristics of natural sunlight. The light intensity of the equipment can be continuously adjusted from 100 to 2000W/m², and it supports one-click switching of multiple standard spectra such as AM1.5G/AM0/D65, meeting the certification requirements of different regions around the world. Engineer Wang did a detailed calculation: "Previously, the annual electricity cost for 10 small-spot xenon lamp devices was 400,000 yuan, and the loss due to lamp replacement and line shutdown was 1.2 million yuan." Now, one 7IS series device can save 60% of electricity, with an annual electricity cost reduction of 240,000 yuan. The xenon lamp supports quick replacement (only 15 minutes for lamp replacement), has a lifespan of 1,000 hours, and the annual lamp replacement cost is only 80,000 yuan, saving 90% of the downtime loss compared to traditional equipment."
Ii. Extreme Environment Material Testing: 2.8m×4.2m format +±0.1% stability, no interruption in testing under high temperature and strong light
Liu Gong, a materials researcher at a certain aerospace science and technology group, once encountered a "fatal interruption" in extreme environment testing: "When we test the entire plate material of a 2.8m×3.5m spacecraft, we need to conduct a 1000-hour aging test at a high temperature of 60℃ and under a strong light of 1500W/m²." The traditional LED equipment has a light attenuation of over 15% at high temperatures. The test was forced to be interrupted after 300 hours, and the 2 million yuan of R&D cost invested in the early stage was wasted. What is even more dangerous is that the ultraviolet band energy of LED equipment is insufficient, making it impossible to simulate the strong ultraviolet irradiation environment in space. Misjudging the anti-aging performance of materials may affect the safety of spacecraft in orbit.
The customized solution of the Saifan 7IS series precisely addresses the pain points in extreme environments. The equipment is customized with a super-large format of 2.8m×4.2m, featuring 12 sets of high-power xenon lamp arrays and a dual-circulation water cooling system. It operates stably in a wide temperature range of -40 ℃ to 60℃. Under 60℃ high temperature, the light intensity drift during continuous 1000 hours of testing is ≤±0.8%, which is far superior to the ±0.3%/h of the industry's 3A-level standard. The uniformity of the light spot is ≤±2.8%, the irradiation dose of the entire board material is consistent, and the temperature difference is ≤±1.5℃, perfectly reproducing extreme light conditions such as space and deserts.
The core performance is even more astonishing: The 7IS series is equipped with self-developed xenon lamp steady-state drive technology, with light intensity stability as low as ±0.1% per 8h, and the repeatability of continuous 1000-hour test data is ≤±0.6%. It covers the full wavelength range of 300nm to 1100nm, with an irradiance of up to 500W/m² in the ultraviolet band, meeting the requirements for strong ultraviolet aging tests of spacecraft materials, weather-resistant coatings, etc. "Now, extreme environment tests can be completed in one go, and the data is directly used for spacecraft design, eliminating the need for repeated restarts." " Mr. Liu introduced that with the help of the "strong irradiation simulation" function of the 7IS series, the team successfully developed a new type of anti-ultraviolet whole plate material, extending its in-orbit service life from 8 years to 15 years. Previously, importing 3A-level xenon lamp equipment cost 18 million yuan, with a delivery period of 8 months. The 7IS series customized model saves 9 million yuan and is delivered within 60 days. It also offers on-site calibration services in high-temperature environments. The durability and precision of domestic xenon lamp equipment have completely broken the monopoly of imports.
Iii. Strong Ultraviolet Research Pilot Test: 220㎡ coverage + 96% uniformity, zero deviation in photocatalytic efficiency test
Professor Zhang from the School of Chemical Engineering of a certain university was once worried about the lighting problem of a 220-square-meter strong ultraviolet photocatalytic pilot platform: "The ultraviolet energy of the traditional supplementary lighting equipment is insufficient. 45 units need to be joined together, and the uniformity of lighting is less than 55%. The catalytic efficiency deviation of the same batch of experiments exceeds 28%, and no top journal paper has been published in four years." More importantly, the LED equipment is unable to provide high-intensity ultraviolet irradiation, making it difficult to meet the scale-up testing requirements in the pilot stage. As a result, the industrialization process of the project has been repeatedly postponed.
The research customization model of the Saifan 7IS series has immediately broken the deadlock. The equipment adopts a "high-power xenon lamp array + distributed uniform light design", with a single unit capable of covering a 220-square-meter pilot platform. The light uniformity reaches 96%, and the parallelism of experimental data has been increased from 55% to 96%. It covers the full wavelength range from 300nm to 1100nm. The ultraviolet (300-400nm), visible (400-760nm), and near-infrared (760-1100nm) bands can be independently adjusted with 1% accuracy. The ultraviolet irradiance can reach up to 800W/m², perfectly matching the strong ultraviolet requirements of different photocatalytic reactions.
"Now, the catalytic efficiency deviation of the same batch of experiments has dropped from 28% to 1.8%. Last year alone, five top-tier journal papers were published and six national patents were applied for. The project has been successfully industrialized, with an annual additional output value exceeding 50 million yuan." " Professor Zhang particularly praised the "intelligent light control system" of the 7IS series: "Through the upper computer software, the ultraviolet light intensity gradient and spectral combination can be set. It can also be linked with the temperature and pressure sensors of the reaction vessel to achieve closed-loop control. Experiments that previously required six people to operate can now be completed by one person." More surprising in energy consumption and maintenance: The annual electricity cost for 45 traditional devices is 280,000 yuan, while for 1 7IS series device, it is only 45,000 yuan, saving 235,000 yuan in electricity costs annually. Xenon lamps support quick replacement, reducing maintenance workload by 80% and completely saying goodbye to the trouble of "frequent lamp replacement and repeated calibration".
Iv. Core Technology Unveiling: Why Can the 7IS Series Balance "Super Wide Range" and "Harsh Scene Adaptation"?
The core competitiveness of the Saifan 7IS series of ultra-wide 3A-level xenon lamp steady-state solar simulators stems from four breakthrough technologies in the industry:
3A-level full indicator compliance framework Adopting the "high-consistency xenon lamp array + 7th generation spectral fitting algorithm", the spectral matching degree (A+), uniformity (A), and stability (A) all indicators meet the IEC 60904-9 3A-level standard. The collaborative control of the xenon lamp array avoids "the attenuation of a single lamp affecting the overall accuracy", ensuring consistent accuracy at every point within the ultra-large radiation area.
Xenon lamp steady-state drive technology: Independently developed constant current and constant voltage drive module, current stability ≤±0.01%, supports independent control of 128 groups of xenon lamps, combined with a dual-circulation water cooling system (xenon lamp circuit temperature control accuracy ±0.1℃), avoids the "pulse fluctuation" and "temperature drift" problems of traditional xenon lamps, and the light intensity stability reaches ±0.1%/8h.
Ultra-large beam uniform light system: Equipped with a 3.5m×6.0m ultra-large size integrating sphere (PTFE coating with a reflectivity of ≥99.5%) + aspheric wide-angle condenser. After 200,000 optical simulations, it achieves "no divergence of large light spots and no distortion at the edges", with a 3.2m×5.0m area uniformity of ≤±3%.
Extreme environment adaptation design The body is made of 6061-T6 military-grade aluminum alloy, with an airtight seal and dust-proof and water-proof design (protection level IP65). It is equipped with a 1000Hz high-sensitivity dual sensor for light intensity and spectrum, and is combined with an AI adaptive calibration algorithm to compensate for errors caused by temperature and voltage fluctuations in real time, ensuring stable long-term operation accuracy in extreme environments.
Five. Not Only equipment, but also a "Partner for Harsh scene lighting testing"
Saifan Optoelectronics is well aware that high-end xenon lamp testing equipment requires full-cycle support
All-dimensional customization The 7IS series supports customized format size (1.2m×1.2m to 3.5m×6.0m), spectral type (AM1.5G/AM0/D65), and installation method (floor-standing/suspended/mobile). For extreme environmental requirements, it can be modified to prevent sand, moisture, and radiation, making it suitable for special scenarios such as aerospace and desert scientific research.
Ultra-fast response service There are 9 regional technical centers across the country, with 100% of commonly used spare parts (including xenon lamps and core components of water cooling systems) in stock. We promise a 7× 24-hour response and on-site maintenance within 24 hours. For instance, a certain photovoltaic enterprise experienced equipment failure just before its international certification. Engineers arrived at the scene within 3 hours and completed the replacement and calibration of the xenon lamp within 1 hour, without delaying the certification progress.
Authoritative calibration guarantee: The equipment comes with a traceable NIST calibration report, supports CNAS laboratory certification, and offers two free on-site calibration services per year (including special calibration in extreme environments). Core components (xenon lamp drive, water cooling system) are guaranteed for 5 years to ensure the long-term validity of test data.
Vi. Future Outlook: Wider format, better compatibility
With the upgrading demands for giant photovoltaic modules, extreme environment materials, and strong ultraviolet research, the Saifan 7IS series is still undergoing continuous technological upgrades:
Develop a 4m×7m ultra-large format model to meet the testing requirements of 6m×8m giant photovoltaic modules and the entire spacecraft cabin.
Optimize the lifespan and energy efficiency of xenon lamps, and introduce a 2000-hour long-life xenon lamp module to further reduce usage costs.
Build the "7IS Series Xenon Lamp Illumination Test Cloud Platform" to achieve remote collaboration among multiple devices, real-time data upload and analysis, and support AI-assisted optimization of extreme environment experiment plans.
From the international certification of giant photovoltaic modules to material testing in extreme environments and then to the scientific research and pilot production of strong ultraviolet rays, with 20 years of technological accumulation, Saifan Optoelectronics has made the "7IS series + 3A precision + xenon lamp strong core" artificial sunlight the "core support" for harsh lighting scenarios. If your work is plagued by "small size, poor durability and incomplete full-spectrum coverage", this xenon lamp lighting equipment that sets a new industry benchmark might just be the key for you to break through the bottleneck.
