I bought xenon lamp equipment. Over three years, I spent 200,000 yuan on lamp replacement and electricity bills, but the data is still inaccurate. If you want to customize a special spectrum, foreign manufacturers have to wait for three months, and the project just falls through... This is the "pitfall" experience that most enterprises encounter when purchasing optical testing equipment. With 20 years of accumulation in optoelectronic technology, Saifan Optoelectronics has developed an LED solar simulator. With the three core advantages of "0.3% accuracy, 11-year maintenance-free, and 72-hour customization", it helps the photovoltaic, aerospace, scientific research, and agricultural fields avoid equipment selection traps, allowing the pace of innovation to be one step ahead.
Photovoltaic R&D: From "Data tug-of-war" to "Breaking the bottleneck in 12 days", efficiency triples
Wang, the R&D director of a perovskite battery enterprise, was once so worried about equipment problems that he couldn't sleep: "I used xenon lamps to measure the battery efficiency. It was 25.2% in the morning and 23.8% in the afternoon, with a deviation of over 6%. I spent half a year verifying the data." The monthly electricity bill for 8 devices is 20,000 yuan. Replacing the lights costs 48,000 yuan a year. The finance department asks me every day for a "cost reduction plan". It was not until the installation of the Saifan LED solar simulator that the research and development finally "stepped on the gas".
The "accuracy" of Saifan lies in its hard technology: The independently developed 5th generation intelligent spectral fitting algorithm, trained with 2 million sets of measured data, has achieved A + level matching degree in the full band from 400nm to 1100nm, and the restoration accuracy in the near-infrared region of 780nm exceeds 98%. It can preset 12 standard spectra such as AM1.5G and AM0 with touch screen operation. After clicking "Start Test", the system automatically generates an IV curve report, and the data deviation is strictly locked within ±0.3%. "For the same batch of batteries now, the data measured today will have a reproduction error of no more than 0.5% next week. There's no need to compete with the data anymore." "
With the help of equipment, Wang's team discovered the core issue of "the battery's near-infrared absorption efficiency being 13% lower" in just 12 days. After optimizing the materials, the efficiency jumped to 27.3%, and the results were published in Nature Photonics. The cost is even more surprising: The power consumption of 650W is only 22% of that of xenon lamps, and the monthly electricity bill for 8 devices has dropped from 20,000 yuan to 4,500 yuan. The 100,000-hour LED lifespan can be used continuously for 11 years, and the operation and maintenance cost over 3 years has been reduced from 150,000 yuan to 16,000 yuan. The money saved was directly used to purchase two new devices. "Choose the right optical equipment and the R&D progress will be at least three years faster!" " Engineer Wang sighed.
Aerospace testing: From "waiting for equipment" to "7-day Customization", reliable even in Extreme environments
The test of spacecraft battery wings requires an extremely cold environment of -40 ℃. The light intensity drift of the xenon lamp equipment exceeds 5%, so the data cannot be used. The solar panels of the Mars rover need AM0 + infrared enhanced spectrum. It will take three months to customize them from abroad. The project will definitely be delayed. Engineer Li from the Beijing Institute of Aerospace Metrology's anxiety once almost caused his team to miss a mission node. The "all-scenario adaptability" of the Saifan LED simulator has become a "savior" for aerospace testing.
The "weather resistance" of the equipment can withstand extreme tests: The 6061-T6 military-grade body and airtight packaging are like wearing a "space protective suit" for the equipment. The temperature fluctuation within the range of -40℃ to 60℃ is ≤±0.3℃, and the light intensity deviation in the 720-hour low-temperature irradiation test is ≤±1.2%. The spectral curve is monitored in real time with professional software, and even the slightest fluctuation can be automatically corrected. Perfectly reproduce the AM0 spectrum in space. In the test of the battery wing of a certain space station, with this precise data, the new coating developed by the team has extended the in-orbit lifespan of the battery wing from 5 years to 15 years.
When it comes to special demands, Saifan's "customization speed" is even more astonishing During the Mars exploration mission, the R&D team completed the design of the "Infrared Enhanced LED module" in 72 hours. By increasing the density of lamp beads in the 800-1100nm band, the irradiance of this band was raised by 30%. The installation and debugging only took 48 hours, which is 98% shorter than the three-month cycle abroad. "Previously, when waiting for equipment, one had to look at others' faces. Now, Saifan can handle it in just seven days. Space missions no longer have to be held back." " Engineer Li said.
Scientific research experiments: From "seizing the low-temperature period" to "generating data at any time", the output of results is 50% faster
In the photocatalytic hydrogen production experiment, for every 1℃ increase in ambient temperature, the catalyst activity drops by 3%. The surface of the xenon lamp equipment exceeds 70℃, the experimental bench gets hot, and the data repeatability is poor. I wanted to adjust the proportion of ultraviolet rays, but the equipment could only be set at a fixed speed. The experiment was stuck for half a year. Professor Zhou's concern from Qingdao University of Science and Technology is a common pain point in the field of scientific research. The "flexibility and stability" of the Saifan LED simulator have finally enabled the laboratory to "operate smoothly".
The "regulating power" of the equipment is comparable to a "palette of light" : The touch screen operation can achieve 1% precision adjustment in the ultraviolet (300-400nm), visible and near-infrared bands. The light intensity can be continuously switched from 1W/m² to 1500W/m². It can also set 8 scene modes such as "day and night alternation" and "pulsed light". After Professor Zhou's team adjusted the ultraviolet proportion to 15%, The efficiency of photocatalytic hydrogen production has been directly increased by 40%, and the cost of green hydrogen has dropped to 35 yuan per kilogram, reaching the commercialization threshold.
The low-heat design is a "blessing" for scientific research: distributed heat dissipation + microchannel water cooling, the surface temperature is only 38℃ during operation, and the fluctuation of the experimental environment is ≤±0.5℃. Students no longer need to rush the "low-temperature period" to conduct experiments. Previously, one set of reliable data was produced every month, but now three sets can be produced every week. The publication speed of research results has increased by 50%, and two papers have already been published in SCI. Professor Zhou mentioned that the agricultural research group used it to simulate the highland light, and the yield of the cultivated barley increased by 25%, which has been promoted in Qinghai.
Agricultural planting: From "relying on the weather for harvest" to "increasing income solely through formula", saving electricity and effort
Lao Yang, a strawberry grower in Shandong, once sighed in front of the greenhouse, "In winter, the light is insufficient. The sweetness of strawberries is only 8 degrees. They are sold at 6 yuan per jin. I lose 100,000 yuan a year on 20 mu of land." The traditional supplementary light consumes a lot of electricity, with a surface temperature exceeding 60℃. If it is too close, it will burn the fruits; if it is too far, the light will be uneven. After installing the Saifan LED solar simulator in 2023, the strawberry garden has completely transformed.
Saifan's "Light Formula" precisely meets the needs of crops: The technical team visits the site to measure the light in the greenhouse and soil fertility, and customizes a "red light 65%+ blue light 10%+2 hours of 380nm ultraviolet light" solution - red light promotes sugar content, blue light enhances hardness, and ultraviolet light increases anthocyanins. The equipment is hung 30 centimeters above the strawberries, with a surface temperature of only 38℃, which will not burn the fruits. The uniformity of light exposure is over 95%.
After one growing season, the sweetness of strawberries rose from 8 degrees to 11 degrees, the yield per mu increased from 2,000 kilograms to 2,150 kilograms, and the price per jin rose to 12 yuan. The annual income of 20 mu of land increased by more than 200,000 yuan. Even more surprising is the electricity bill: With a power consumption of 650W, it saves 70% compared to traditional fill lights, and the monthly electricity bill is only 360 yuan. "Before, growing strawberries was dependent on the weather. Now, with the LED light from Saifan, it's both worry-free and profitable. More than ten farmers around have followed me to buy!" " Old Yang said with a smile.
