"Save 15,000 yuan on electricity bills every month, no need to replace the lights for three years, and the test data is even more accurate than before!" " This is the genuine feedback from a certain photovoltaic enterprise after using the Saifan LED solar simulator. While traditional xenon lamp simulators are still being held back by the industry due to the predicament of "high energy consumption, short lifespan and difficult maintenance", Saifan Optoelectronics, with its 20 years of accumulation in optoelectronic technology and its independently developed core LED technology, has created a new generation of solar simulators that are "energy-saving, precise and long-lasting", bringing about a "light testing innovation" to the photovoltaic, aerospace, scientific research, agriculture and other fields. Let green and efficient optical technology truly be implemented in production and research and development.
Photovoltaic R&D: 650W low consumption + 10,000 hours of long life, saving "half a production line" in a year
Previously, there were 8 xenon lamp simulators, each with a power of 3000W. In summer, two more air conditioners had to be turned on in the laboratory, and the monthly electricity bill was 21,000 yuan. Moreover, the lifespan of xenon lamps is only 1,000 hours. They need to be replaced every six months, each time costing 5,000 yuan. Additionally, they have to be shut down for three days for calibration. The annual maintenance cost alone exceeds 120,000 yuan." Wang, the R&D director of a leading photovoltaic enterprise, is full of helplessness when talking about traditional equipment. It was not until 2023 that the team was pleasantly surprised by the changes in cost and efficiency when six Saifan LED solar simulators were introduced.
Saifan's LED technology directly addresses the pain points of the industry: By adopting self-packaged high-efficiency LED beads and combining with the "multi-chip integration + optical lens optimization" technology, the overall power consumption of the machine is only 650W, which is only 22% of that of xenon lamp equipment. The monthly electricity cost for 6 devices has been reduced from 21,000 yuan to 4,200 yuan, saving over 200,000 yuan in electricity costs annually. More importantly, the "longevity gene" of LED: Relying on the "low thermal resistance packaging + intelligent temperature control" technology, the lifespan of the light source can reach up to 10,000 hours. Calculated based on an 8-hour daily usage, there is no need to replace the lamp in three years. This not only saves an annual lamp replacement cost of 48,000 yuan but also avoids the research and development delay caused by "shutdown calibration".
In terms of the core "accuracy", LED technology is equally resilient: the full-band spectral matching degree from 400nm to 1100nm reaches A + level (0.875-1.125), and the near-infrared region restoration accuracy from 780 to 1100nm exceeds 98%. The independently developed "real-time spectral calibration algorithm" can correct the illumination deviation in real time, with the light intensity fluctuation rate as low as ±0.3% per hour, and the deviation of continuous 10-hour test data is ≤1%. "Previously, when measuring perovskite solar cells, the morning data was 25.1%, but it dropped to 23.8% in the afternoon on a cloudy day. Now, the data measured today will have an error of no more than 0.5% when reproduced next week." " With the help of equipment, Wang's team identified the shortcoming of battery near-infrared absorption in just 12 days, increasing the efficiency from 25.1% to 27.3% and shortening the research and development cycle by 60%. The related achievements were rapidly advanced to pilot production. "Saifan LED simulator, the money saved in a year is enough to buy half a small test production line. This is truly the 'king of cost performance' in photovoltaic research and development!"
Aerospace test: -40℃ weather resistance + LED low-temperature stability, replicating space light with "zero deviation"
"In-orbit life assessment of spacecraft battery wings: A 1% deviation in light intensity could lead to a three-year error. Traditional xenon lamps have a light intensity drift of over 5% at a low temperature of -40 ℃, which is simply not worth using." " Sister Li, a test engineer from a certain team in China's aerospace industry, was once troubled by the simulation of the space environment. The "extreme adaptability" of the Saifan LED solar simulator has completely solved this problem.
Saifan uses military-grade silicon carbide substrate LED beads. Within the temperature range of -40 ℃ to 60℃, the luminous efficiency fluctuates by no more than ±2%. Paired with a 6061-T6 aluminum alloy body and an airtight packaging design, the equipment can operate stably for 720 hours without failure in extreme environments. For the space AM0 spectrum (solar radiation without atmospheric filtering), the R&D team, through "training with 200,000 sets of space spectral data", optimized the band ratio of the LED light source, precisely removed atmospheric interference, and the irradiance error was ≤±1%, perfectly regenerating solar radiation in the universe. Previously, when using xenon lamps to test the aging of battery wings, the data deviation exceeded 8% after 720 hours. Now, with the use of Saifan LED equipment, the deviation has always been controlled within 1.2%. Finally, we can deliver a perfect answer sheet for the space mission.
During the Mars exploration mission, the Saifan team demonstrated the "rapid customization power" of LED technology: they completed the development of the "Infrared Enhanced LED module" in just 7 days. By increasing the density of LED beads in the 800-1100nm band, they raised the irradiance of this band by 30%, perfectly matching the lighting characteristics of the Martian surface. Relying on this module, the power generation efficiency of the Mars rover's solar panels has increased by 22%, solving the "energy anxiety" in deep space exploration. LED technology has transformed space light simulation from "barely meeting standards" to "precise and reliable", which is the greatest guarantee for aerospace safety. Sister Li sighed.
Scientific research agriculture: 1% precision regulation + low heat generation, "Double Harvest" of light experiments and planting
In the photocatalytic hydrogen production experiment, for every 1℃ increase in ambient temperature, the activity of the catalyst drops by 3%. Previously, when using xenon lamp equipment, the surface temperature exceeded 70℃, and the experimental bench became extremely hot, resulting in extremely poor data repeatability. The concern of Professor Zhou from Qingdao University of Science and Technology is a common pain point in the field of scientific research. The "low heat generation advantage" of the Saifan LED solar simulator has finally made the experiment "stable and controllable".
Saifan adopts the "distributed heat dissipation + microchannel water cooling" technology. When the equipment is in operation, the surface temperature is only 38℃, and the temperature fluctuation of the experimental environment is ≤±0.5℃, ensuring the reliability of the data. Its "customization" capability further enhances scientific research: 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". "Nowadays, when students conduct experiments, they no longer have to rush during the 'low-temperature period'. They can obtain stable data at any time, and the progress of their research has directly increased by 50%." "
In the agricultural sector, the "low heat generation" of leds is a "blessing" for farmers. In the greenhouse of Lao Yang, a strawberry grower in Shandong Province, the Saifan LED simulator is suspended 30 centimeters above the strawberries. When it is in operation, the surface temperature is only 38℃, which neither burns the fruits nor fails to ensure uniform lighting. With the customized solution of "65% red light + 10% blue light +2 hours of 380nm ultraviolet light", the sweetness of strawberries has risen from 8 degrees to 11 degrees, the anthocyanin content has increased by 18%, the yield per mu has increased from 2,000 kilograms to 2,150 kilograms, and the price per jin has risen from 6 yuan to 12 yuan. "Previously, sodium lamps were used for supplementary lighting, and the monthly electricity bill was 1,200 yuan. Now, with the Saifan LED equipment, it only costs 360 yuan per month, saving 10,000 yuan in electricity bills a year and earning an additional 200,000 yuan. This equipment is worth it!" " Nowadays, Lao Yang's strawberry garden has become a local "Science and Technology Agriculture demonstration base", and more than ten surrounding growers have followed suit and replaced their equipment with Saifan LED devices.
Full-cycle service: 3-year warranty + 48-hour response, "zero worries" for use
