In fields such as photovoltaics, aerospace, and agriculture, where extremely high precision of light is required, the limitations of traditional light sources are becoming increasingly prominent - low testing efficiency, large data fluctuations, and high maintenance costs, which have become the key bottlenecks restricting industrial innovation. With 20 years of accumulation in optoelectronic technology, Saifan Optoelectronics has launched a large-format 3A-level LED steady-state solar simulator. Centered on "accuracy, stability and efficiency", it redefines the standards for light testing and provides reliable light energy solutions for global customers.
Three core advantages, solving industry pain points
1. 3A-level spectral accuracy, zero data deviation
By using an array of over 2,000 LED chips of specific wavelengths and through A precise spectral fitting algorithm, it achieves A+ level spectral matching across the entire band from 350nm to 1100nm (IEC 60904-9 standard). The energy restoration accuracy in the near-infrared region exceeds 98%, and even a 0.5% absorption difference can be accurately captured.
The light intensity stability reaches 0.08% for 8 hours, and the continuous test data reproduction error is ≤0.1%. It completely bids farewell to the trouble of "data flickering on cloudy days", ensuring that the R&D and mass production data are highly consistent.
2. Large-scale coverage, doubling efficiency
The standard model has a spot size of 1.2m×1.2m, while the customized model can be expanded to 2m×3m. It can cover the entire photovoltaic module or large-sized samples of aerospace materials at one time without the need for segmented testing.
The test time has been compressed from 40 minutes for traditional equipment to 8 minutes, and the production line efficiency has increased by more than three times, helping enterprises respond quickly to market changes.
3. Extra-long lifespan and energy efficiency, saving you time and money for ten years
The LED light source has a lifespan of up to 100,000 hours (usable for 34 years based on 8 hours per day), and features a maintenance-free design, eliminating the need for frequent lamp replacement and calibration.
The overall power consumption of the machine is only 650W, which is 70% more energy-efficient than traditional xenon lamps. A single production line can save over 200,000 yuan in electricity costs annually, and the long-term usage cost has been significantly reduced.
All-scenario applications empower innovation in multiple fields
Photovoltaic industry: The core engine for Quality improvement and efficiency enhancement
After the introduction of A certain photovoltaic enterprise, the consistency of battery efficiency testing has significantly improved. The rate of A-grade products has jumped from 88% to 93%, and the annual loss of defective products has been reduced by over 10 million yuan.
The automated test line operates at a speed of 60 cells per minute, combined with ±3% spatial uniformity, ensuring consistent light exposure for each inch of battery and accelerating the commercialization process of high-efficiency batteries.
Aerospace testing: A reliable partner in extreme environments
Customized models can simulate extreme light conditions such as those on Mars and the Moon. The light intensity stability remains at 1% even in an extremely cold environment of -40℃, providing ground verification support for spacecraft solar panels.
Irradiation error ≤1% to avoid risks to space missions caused by test deviations and ensure in-orbit safety.
Agricultural Research: The "Sunshine Assistant" for Precise Regulation
By precisely regulating the spectral band, the uniformity of crop growth is promoted to 95%, helping the experimental greenhouse achieve increased production and efficiency.
After the strawberry growers in Shandong adopted it, the annual income of 20 mu of land increased by more than 200,000 yuan, verifying the enabling value of light technology to agriculture.
Technical depth builds industry benchmarks
The leading position of Saifan Optoelectronics stems from two core technologies:
Spectral testing technology: Relying on self-developed spectrometers and monochromators, high-precision optical analysis and calibration are achieved to ensure that data can be traced back to international standards.
Precision motion control technology: Through ZEMAX optical simulation optimization, the spot uniformity is ≤±2%, and it can still maintain millimeter-level accuracy in large-format tests.
At present, the equipment has served over 200 customers worldwide, helping to shorten the R&D cycle of photovoltaic by 60%, supporting 12 national-level space missions, and promoting the publication of more than 20 SCI papers.
The future is here, and light embarks on a new journey
Saifan Optoelectronics adheres to the principle of "Quality First, Customer Satisfaction", and continuously promotes the in-depth integration of optical technology and industry. The large-format 3A-level LED steady-state solar simulator is not only a testing tool but also the cornerstone of innovation - it makes R&D no longer constrained by weather, makes mass production data more reliable, and makes the exploration path more relaxed.
