In the field of optical testing equipment, technological innovation is the core driving force for the development of the industry. Saifan Optoelectronics' LED solar simulators have always been driven by technological breakthroughs. From the ultimate pursuit of spectral accuracy to the technological innovation of stable output, from the flexible construction of customized solutions to the comprehensive upgrade of the service ecosystem, a series of original technological innovations have made it a benchmark product in the field of light testing, continuously injecting technological impetus into the innovative development of various industries.
Spectral simulation technology: Seamlessly connecting "artificial sunlight" with natural light
The accuracy of spectral simulation is the core technical indicator of solar simulators. Saifan Optoelectronics has achieved breakthrough innovation in this field. Its independently developed fifth-generation intelligent spectral fitting algorithm, trained on over 100,000 sets of natural sunlight spectral data, can dynamically correct the spectral deviation of LED arrays in real time, achieving a spectral matching accuracy within ±0.5% (the industry average is ±2%). This technology has been granted three national invention patents.
The innovative application of multi-band high-precision LED arrays has extended the spectral coverage from 280nm deep ultraviolet to 1800nm near-infrared, perfectly reproducing international standard spectra such as AM0 and AM1.5G. Compared with traditional xenon lamp simulators, the spectral stability of Saifan equipment is improved by five times, and there is no spectral drift problem of xenon lamps. Test data from a photovoltaic laboratory of a certain university shows that during the continuous 100-hour test, the spectral deviation of the Saifan simulator was always controlled within ±0.8%, while the traditional equipment had already shown a deviation of 1.5% at the 20th hour. This stability significantly enhances the credibility of the scientific research data.
Stable output technology: The "Anchor of Light Intensity" in Extreme environments
The stable output of light intensity directly determines the reliability of the experimental data, and the closed-loop feedback control system of Saifan Optoelectronics provides technical support for this. This system adopts a 0.1ms high-sensitivity light intensity sensor (commonly 1ms in the industry), combined with a self-developed FPGA high-speed control chip. The response time from light intensity fluctuation detection to compensation is less than 50ms, ensuring that the fluctuation is controlled within ±0.5% per hour (the response delay of traditional equipment is > 200ms, and the fluctuation often exceeds ±2%).
In terms of structural design, Saifan innovatively adopts a military-grade structure where the optical chamber and the mechanical transmission chamber are strictly separated, effectively avoiding the interference of mechanical vibration and temperature changes on light intensity. Even in extreme environments ranging from -40 ℃ to 60℃, the equipment can still operate stably. The test and verification by the Beijing Institute of Aerospace Metrology: After continuous operation for 720 hours in a -40 ℃ low-temperature chamber, the cumulative light intensity fluctuation of the Saifan simulator does not exceed ±1.2%. This performance makes it the only equipment in China to have passed the aerospace "Space Light Simulation Certification".
Customized technology: Creating "Light Environment Solutions" for diverse scenarios
The lighting requirements vary greatly across different industries. The modular design technology of Saifan Optoelectronics makes customization possible. The equipment supports flexible customization of spot sizes ranging from Φ50mm to 2m×2m. By replacing optical lens groups with different focal lengths, the spot size can be adjusted within one hour, meeting the full-scenario requirements from chip-level testing to large component verification.
Spectral customization technology is the core competitiveness of Saifan. Users can independently adjust the proportion of light in each band through the device's touch interface. The system is equipped with over 100 industry-specific spectral templates, covering typical application scenarios in fields such as photovoltaic, aerospace, and agriculture. The Yunnan flower base completed the debugging of the lighting scheme for blue roses in just 3 days by calling on the "Plateau Ultraviolet + Red Light Enhancement" template and adjusting the parameters according to custom requirements, saving 20 days compared to the traditional trial-and-error method. In response to the special demands of the aerospace field, Saifan has also developed an angle-adjustable light source system, with a continuously adjustable irradiation Angle from 0° to 90°, perfectly simulating the sun's movement trajectory within the ecliptic plane.
Intelligent operation and maintenance technology: Building technical support throughout the entire life cycle
Saifan Optoelectronics innovatively introduced Internet of Things (iot) technology into equipment operation and maintenance and developed an intelligent remote monitoring system. Users can view the operation parameters, spectral curves and fault warnings of the equipment in real time through the mobile phone APP. The system can predict the attenuation trend of the light source 72 hours in advance to avoid sudden faults affecting the experimental progress. The usage experience of a certain environmental monitoring station shows that this system has increased the preventive maintenance rate of equipment by 60% and reduced unplanned downtime by 80%.
In terms of technical traceability, Saifan has established a spectral traceability system directly connected to the National Institute of Metrology, China. The annual traceability error of the equipment's measurement values can be controlled within ±0.3%, and the test data is globally recognized. This technological advantage has made Saifan simulators the "data benchmark equipment" for over 200 customers, and its market share in the photovoltaic, aerospace and other fields has remained the top for five consecutive years.
From algorithm innovation to structural design, from hardware upgrades to intelligent operation and maintenance, every technological breakthrough of Saifan Optoelectronics' solar simulators targets the pain points of the industry. These innovations not only bring the equipment performance to the international leading level, but also upgrade the light testing from a simple equipment supply to a "light environment solution" service. As a certain aerospace client commented: "The technological innovation of Saifan does not lie in the accumulation of parameters, but in truly solving our testing problems in extreme environments." Choosing Saifan means choosing to walk hand in hand with innovators in light testing technology, ensuring that every experiment is at the forefront of technology.
