In photovoltaic testing, material research, photocatalysis experiments and aerospace measurement scenarios, stable, controllable and reproducible standard light is the core for data credibility, certification success and research acceleration. Traditional xenon lamp simulators have short lifespan, high energy consumption, slow preheating and frequent maintenance. Pulsed light sources are difficult to meet long-term steady-state testing requirements. Natural light is uncontrollable and has large data drift, causing laboratories and production lines to be constantly troubled by "testing based on the weather". 

Safan Optoelectronics has been deeply engaged in the field of light simulation for 20 years and has launched the 3A level LED steady-state solar light simulator. With full indicators of 3A certification, LED steady-state long lifespan, ultra-low energy consumption, instantaneous startup and ultra-large area uniform light, it redefines the new benchmark for solar light simulation, providing more stable, more energy-efficient, more accurate and more durable artificial standard sunlight for research and industry. 

1. 3A Gold Standard, Full Indicators Benchmarking International Top Standards

Strictly following the authoritative standards of IEC 60904-9 and ASTM E927, the three core indicators are all A-level, and some indicators reach A+ level. The data is globally recognized: 

Spectral matching A-level: Using multi-band LED chip arrays and intelligent fitting algorithms, covering the entire 350?1100nm wavelength range, accurately reproducing the AM0 and AM1.5G standard spectra, with a matching degree of 0.875?1.125 (A+ level), and the near-infrared energy restoration accuracy exceeds 98%; 

Irradiation uniformity A-level: Using a large integral sphere + aspheric light uniformity system, after 100,000 optical simulations, the large-area uniformity is ≤±3%, without dark areas or hotspots; 

Time stability A-level: Autonomous constant current drive + light feedback closed-loop, light intensity drift ≤±0.05%/8h, continuous test data reproducibility error ≤0.1%. 

From I-V testing of crystalline silicon, perovskite, and tandem batteries to component efficiency calibration and material weathering aging, the data passes international certifications such as TÜV and UL once, with zero rework during submission, and smoother export. 

2. LED Steady-State Innovation: Longevity and Energy Efficiency, Saying Goodbye to Frequent Maintenance 

Disrupting the traditional xenon lamp solution with solid-state LED sources, it brings full lifecycle cost reduction and efficiency improvement: 

Extremely long lifespan: Imported high-power LED chips, with a lifespan of up to 100,000 hours. Calculated at 8 hours per day, it can be used continuously for over 30 years, basically eliminating the need for light source replacement; 

Ultra-efficient energy consumption: With a photoelectric conversion efficiency of 35%, energy consumption is reduced by 80% compared to traditional xenon lamp equipment, with annual energy savings of over 500,000 yuan, more green and compliant; 

Instantaneous startup: No preheating required, reaching the rated light intensity within 1 second, enabling experiments and production line efficiency to increase by 5 times; 

No thermal interference: Low heat output, no excessive infrared radiation, avoiding sample deformation due to heating, making the test more realistic and reliable. 

Completely saying goodbye to "frequent lamp replacement, machine shutdown for calibration, high electricity costs", maintenance costs have been reduced by 80%, and equipment stability has increased by 300%. 

3. Ultra-large Area + Intelligent Light Control: More Efficient Testing, More Flexible Adaptation 

Facing the needs of large-sized components and high-precision research, Safan uses engineering capabilities to solve industry pain points: 

Ultra-large area coverage: Supports a maximum of 2.4m×4.8m ultra-large irradiation area, testing the entire board at once, without the need for segmented assembly, reducing testing time from 40 minutes to 8 minutes, efficiency increasing by more than 3 times; 

Multi-unit independent regulation: Supports 288 groups of LED independent dimming, with precise spectral and light intensity adjustment (0.5?3Sun), with a collimation angle of ≤±3°, meeting all scenarios from small light spot research to large-area production; Intelligent temperature control and stable light: 8th generation steady-state drive + dual closed-loop control, current stability ≤ ±0.01%, no light attenuation or spectral drift during long-term operation, suitable for 7×24-hour continuous testing.
