In the era where the "dual carbon" goal is leading and environmental governance and new energy technologies are developing rapidly, photocatalysis, as the core technology connecting light energy and chemical energy conversion, is becoming the key key to solving the energy crisis and purifying the ecological environment. And stable, high-intensity, and full-spectrum light sources are precisely the "heart" of photocatalysis experiments and applications. After 20 years of deep research in the field of optoelectronics, Sevan Optoelectronics, relying on its profound accumulation of spectral technology, has匠心crafted the 7ILX150P/7ILX500P series photocatalytic xenon light sources. With precise output similar to sunlight， extremely stable performance， and efficient utilization of light energy， it has become the preferred "light engine" for scientific researchers and industrial R&D in the global photocatalysis field.
I. Sun-like full-spectrum, "ideal sunlight" for catalytic reactions
The efficiency and selectivity of photocatalytic reactions highly depend on the spectral matching degree of the light source. The Sefan Photovoltaic photocatalytic xenon lamp is equipped with high-quality imported short-arc xenon lamps from Germany, perfectly outputting a continuous spectrum ranging from 200nm to 2500nm, with a precise color temperature of 6000K and a color rendering index (Ra) greater than 90. It closely matches the spectrum of the midday sun and is highly praised in the industry as an "artificial small sun".
Strong ultraviolet excitation: Adequate ultraviolet wavelength (200-400nm) energy efficiently excites mainstream photocatalysts such as TiO₂ and g-C₃N₄, generating sufficient electron-hole pairs, providing sufficient initial power for reactions such as water splitting for hydrogen production, CO₂ reduction, and pollutant degradation.
Full spectral coverage: Seamless coverage of visible light and near-infrared wavelengths, not only meeting the requirements of conventional photocatalysis, but also suitable for photothermal collaborative catalysis and new catalysts with wide spectral response, allowing each catalyst to absorb the most suitable light energy and release the maximum catalytic potential.
No spectral line missing: Different from the discontinuity of light spectra in LED and other light sources, the continuous and smooth spectrum of the Sefan xenon lamp ensures that the experimental conditions are highly consistent with the real sunlight environment, making the experimental data more persuasive and repeatable.
II. High light intensity and stability, "reliable cornerstone" of experimental data
The photocatalytic experiment has a long cycle and is sensitive to light power fluctuations. The stability of the light source directly determines the reliability of the data. Sefan Photovoltaic has overcome industry pain points with cutting-edge technology and provides long-term precise experiments.
Ultra-high energy density: Adopting an innovative reflector plate focusing optical path design, the light energy utilization rate is increased to 3-4 times that of traditional light sources. The light intensity output is far beyond that of similar products. Beijing Sefan Photovoltaic Instrument Co., Ltd. 7ILX150P has a brightness of up to 20000cd/cm², and 7ILX500P even reaches 40000cd/cm², easily achieving the standard output of 1 solar light intensity (1 Sun), meeting the requirements of efficient catalysis and rapid experiments.
Long-term stable zero drift: A built-in high-stability linear power supply system is used to achieve long-term stability of light power <2%. Continuous operation for 8 hours or even several days, with negligible light intensity fluctuations, and constant spectral energy distribution. Completely getting rid of the dilemma of "light source drift causing re-experiments", ensuring the accuracy and credibility of each set of catalytic efficiency and reaction kinetics data.
Long-life durable design: Optimizing the intelligent heat dissipation system to effectively control the temperature of the lamp body, significantly extending the lifespan of core components. Beijing Sefan Photovoltaic Instrument Co., Ltd. 7ILX150P bulb lifespan reaches 3000 hours, and 7ILX500P reaches 2000 hours, reducing the hassle of frequent replacement of consumables and lowering the overall experimental cost.
III. Modular flexible design, suitable for all scenarios of catalytic research
Sefan Photovoltaic is well-versed in the diversity of photocatalytic research scenarios. The products are designed with modular and highly compatible features, easily adapting to various experimental needs, covering from basic research to industrial research.
Dual power precise selection: Providing two mainstream models of 150W (7ILX150P) and 500W (7ILX500P). The small power is suitable for basic catalysis and micro-reaction research; the large power is specifically designed for high-demand scenarios, meeting the strong light requirements of photothermal catalysis, large-scale pollutant treatment, and efficient hydrogen production, etc.
Convenient filter light switching: The light source system is reserved with standardized filter seat, which can be quickly matched with various filter films such as ultraviolet, visible light, and infrared, easily achieving single-color light, specific wavelength photocatalytic experiments, and accurately exploring the spectral response characteristics of the catalyst.
All-round light path compatibility: 6° precise beam angle design, uniform light spot, can be directly coupled with optical fibers, realizing multi-position, remote, and sealed environment illumination. It can be combined with standard photocatalytic reactors, or flexibly integrated into complex devices such as photoelectrochemical testing, in-situ spectroscopic characterization, hydrogen production / CO₂ reduction evaluation systems, etc., with extremely strong adaptability.
4. Empowering green technology, covering all fields of catalytic applications
With outstanding performance, the Sefan photoelectric photocatalytic xenon lamp has become a benchmark equipment in fields such as water splitting for hydrogen production, CO₂ reduction, environmental purification, and material research, helping thousands of scientific research teams and enterprises overcome technical difficulties.
Clean energy conversion: Providing stable and strong light for photocatalytic decomposition of water for hydrogen production and CO₂ reduction to help breakthroughs in "liquid sunlight" and artificial photosynthesis technologies, and efficiently converting greenhouse gases into clean fuels.
Environmental governance: Efficiently stimulating catalysts to degrade dye wastewater, pesticide residues, VOCs, etc., providing core light solutions for water treatment and air purification technology research.
Advanced material research: Supporting the performance testing and efficiency optimization of new visible light / infrared-responsive catalysts, perovskite materials, and photoelectrodes, accelerating the transition of next-generation photocatalytic materials from the laboratory to industrialization.
