While traditional xenon lamp simulators are still plagued by the industry's problems of "high energy consumption, short lifespan and difficult maintenance", Saifan Optoelectronics has launched a new generation of LED solar simulators with its 20 years of optoelectronic technology accumulation. It not only continues the core capability of "precisely replicating natural light", but also features the LED technology advantages of "low power consumption, long lifespan and easy operation". It brings a "light testing revolution" to fields such as photovoltaics, aerospace, scientific research, and agriculture, making "high efficiency and energy conservation" and "precision and stability" no longer optional questions.
Photovoltaic R&D: 650W low power consumption + 0.3% stability, achieving a double harvest of cost reduction and efficiency
Previously, when using xenon lamp simulators, each unit had a power of 3000W. With eight devices in one R&D laboratory, the monthly electricity bill would exceed 20,000 yuan. Moreover, the lifespan of xenon lamps is only 1,000 hours. They need to be replaced every six months, with each replacement costing 5,000 yuan. Additionally, they have to be shut down for calibration." Wang, the R&D director of a certain photovoltaic enterprise, was once extremely troubled by the "high cost" of traditional equipment. After the introduction of the Saifan LED solar simulator, the balance between cost and efficiency has completely tilted.
The "energy-saving" feature of this device from Saifan directly addresses the pain point: it adopts high-efficiency LED light sources, with the entire machine's power consumption being only 650W, which is only 22% of that of traditional xenon lamp equipment - the monthly electricity cost for 8 devices has been reduced from 20,000 yuan to 4,500 yuan, saving over 180,000 yuan in electricity costs annually. More importantly, the "longevity feature" of LED: the lifespan of the light source is up to 10,000 hours. Calculated based on 8 hours of daily use, it does not need to be replaced for three years, completely eliminating the trouble of "frequent lamp replacement and shutdown calibration". Just the cost of lamp replacement alone can save 48,000 yuan annually.
In terms of the core "accuracy", it also performs exceptionally well: the full-band spectral matching degree from 400nm to 1100nm reaches the A + level (0.875-1.125), and the reduction accuracy in the near-infrared region from 780-1100nm exceeds 98%. The light intensity fluctuation is as low as ±0.3% per hour, and the deviation of the test data for 10 consecutive hours is ≤1%. With the help of the equipment, Wang's team identified the shortcoming of near-infrared absorption in perovskite solar cells within 12 days, increasing the efficiency from 25.1% to 27.3% and shortening the research and development cycle by 60%. "Saifan LED simulator not only helps us reduce costs but also improves efficiency. This is truly the 'ideal equipment' for photovoltaic research and development!" " Engineer Wang sighed.
Aerospace testing: -40℃ weather resistance + LED low-temperature stability, more reliable in replicating space light
The testing of spacecraft battery wings requires simulating the extremely cold environment of -40 ℃ in space. Traditional xenon lamp equipment is prone to "light intensity drift" at low temperatures, and even the lamp tubes may break. In extremely cold environments, the light intensity fluctuation of the Saifan LED simulator is always ≤±1.2%, and its stability far exceeds expectations. Sister Li, a test engineer from a certain team of China Aerospace, highly praised the "extreme environmental adaptability" of Saifan's LED equipment.
The "low-temperature stability" of LED light sources is a key advantage: Unlike xenon lamps that rely on gas discharge and are easily affected at low temperatures, the military-grade LED beads used by Saifan have a luminous efficiency fluctuation of no more than ±2% within the range of -40 ℃ to 60℃. Paired with a 6061-T6 aluminum alloy body and airtight packaging, the equipment can operate stably for 720 hours without failure in a space simulation environment. For the space AM0 spectrum, it is calibrated through 200,000 sets of space data, precisely eliminating atmospheric interference, with an irradiance error of ≤±1%, perfectly reproducing solar radiation in the universe.
In the Mars exploration mission, the Saifan team, relying on the "rapid customization capability" of leds, completed the development of the "Infrared Enhanced LED module" in just 7 days, increasing the irradiance in the 800-1100nm band by 30%, perfectly matching the light characteristics of the Martian surface and helping to increase the power generation efficiency of the Mars rover's solar panels by 22%. LED technology makes space light simulation more stable and flexible, which provides a core guarantee for the power safety of space missions. Sister Li said.
Scientific research agriculture: 1% precision control + LED low heat generation, more flexible light experiments
The photocatalytic hydrogen production experiment requires precise adjustment of the proportion of the ultraviolet band. Traditional xenon lamp equipment not only has high power consumption but also generates a large amount of heat, causing the temperature of the experimental environment to rise and affecting the activity of the catalyst. The Saifan LED simulator has low power consumption and generates less heat. The ambient temperature fluctuation is ≤±0.5℃, making the experimental data more reliable. Professor Zhou from Qingdao University of Science and Technology has a deep understanding of the "low heat generation advantage" of LED equipment.
The "customization" capability of the Saifan LED solar simulator is equally outstanding The ultraviolet (350-400nm), visible (400-760nm), and near-infrared (760-1100nm) bands support 1% precision adjustment. The light intensity can be freely switched from 0.1sun to 2sun, and it can also simulate eight lighting scenarios such as day-night alternations and pulsed light. Professor Zhou's team successfully increased the photocatalytic hydrogen production efficiency by 40% by adjusting the ultraviolet proportion of the LED light source (from 5% to 15%), and the results were published in "Applied Catalysis B: Environmental".
In the agricultural sector, the "low heat generation" of LED is an advantage: In the greenhouse of strawberry grower Lao Yang in Shandong, the Saifan LED simulator is hung 30 centimeters above the strawberries. When it is in operation, the surface temperature is only 38℃, which will not burn the crops. However, the surface temperature of traditional supplementary lighting lamps exceeds 60℃, and they must be kept at least one meter away from the crops, which affects the uniformity of light. With the LED lighting solution of "65% red light + 10% blue light + ultraviolet assistance", the sweetness of Lao Yang's strawberries has increased from 8 degrees to 11 degrees, the yield per mu has increased by 150 kilograms, the annual profit has increased by 200,000 yuan, and the electricity cost is 70% lower than that of traditional supplementary lighting. "LED light is both good and energy-efficient. Growing strawberries no longer depends on the weather!" " Old Yang said with a smile.
Full-cycle service: LED maintenance-free + quick response, more worry-free use
Saifan Optoelectronics is well aware that the "long-term value" of LED equipment requires service support. In view of the characteristics of LED light sources, Saifan offers a "3-year warranty" service. During this period, if the light source attenuation exceeds 10%, it will be replaced free of charge. Seven major spare parts centers across the country reserve over 95% of commonly used components, providing 7× 24-hour response. Equipment malfunctions can be repaired within 48 hours. A photovoltaic enterprise's production line simulator suddenly experienced a software failure. Saifan engineers provided remote guidance and solved the problem within one hour, without affecting production. For scientific research users, we offer "LED spectral calibration training" to ensure that the team can independently complete daily maintenance and extend the precise service life of the equipment.
Today, Saifan LED solar simulators have served over 200 customers worldwide. The repurchase rate of core customers is 85%, and 80% of new customers choose the LED model due to its "energy-saving and long-lasting" features. From cost reduction and efficiency improvement in photovoltaic research and development to the stability and reliability of aerospace testing, and then to the flexibility and precision of scientific research and agriculture, Saifan has redefined "solar simulation" with LED technology, enabling "green light technology" to truly empower industrial innovation. If your light testing needs are still plagued by "high energy consumption and short lifespan", the Saifan LED solar simulator might just be the key for you to break through the deadlock.
