The core performance of the solar light simulator, photocatalytic light source, and photovoltaic characterization system is highly dependent on the spectral quality and arc stability of the xenon light source body. Ordinary xenon lamps generally have problems such as arc drift, light spot divergence, spectral distortion, slow startup, and light color attenuation during the lifespan; a longer arc length will cause low concentrating efficiency, poor light spot uniformity, directly hindering the spectral matching and irradiation uniformity indicators of the entire machine, and failing to meet the strict standards of a 3A-level solar light simulator; the spectral shift caused by the aging of the lamp body will cause data dispersion and distortion in photovoltaic IV tests, photocatalytic aging experiments, and spectral response characterization, restricting the data credibility of scientific research experiments and photovoltaic quality inspection.

By deeply researching and developing high-quality xenon light source components, Saifan Optoelectronics has launched the 7XB-500-HTC spherical xenon lamp, a 500W horizontal short arc spherical xenon lamp with a cable-extracted structure. With its ultra-short arc, small light spot, full continuous spectral range of UV-IR, 6000K daylight color temperature, long-life stable light color, it provides high-performance core light-emitting core for 3A-level solar light simulators, photocatalytic light sources, and various photovoltaic testing equipment, solving the problems of unstable arc, difficult light concentration, spectral drift, and poor light color of ordinary xenon lamps, ensuring the consistency and reliability of the entire optical system during long-term testing.

Ultra-short arc point light source, controllable efficient light spot

The 7XB-500-HTC spherical xenon lamp has an extremely short arc structure, with stable arc shape and small fluctuation amplitude, forming the light-emitting characteristics of a point source. The light spot is compact and small, suitable for the optical convergence design of an ellipsoidal reflector, significantly improving the light energy collection efficiency, effectively reducing the difficulty of light path design, and helping the equipment achieve high uniformity and large light spot output. After lighting, it quickly climbs to the rated light output without the need for long preheating, reducing the initial waiting time and suitable for high-frequency startup conditions of scientific research experiments. The horizontal installation structure matches the mechanical interface of the Saifan series light source room, the assembly and positioning are convenient, the cable-extracted method is conducive to the integration of internal wiring of the equipment, and is suitable for the assembly requirements of the entire machine equipment.

Excellent arc drift resistance, during the entire lighting process, the arc has no obvious drift, avoiding the shift of the light spot center and the gradient of light intensity on the irradiation surface caused by arc drift, reducing the risk of overall uniformity degradation from the source of the light, and laying a solid hardware foundation for the 3A-level solar light simulator to achieve the indicators.

Full-band continuous spectral range, highly accurate simulation of natural sunlight

The lamp output covers a wide range of continuous smooth spectral in the UV-Visible-IR, with no obvious spectral break, stable color temperature of 6000K, color rendering index Ra can reach 94, the light color is highly close to real sunlight, after correction by the filter, it can accurately achieve the AM1.5G, AM0 standard solar light spectrum, suitable for photovoltaic device calibration, photocatalytic aging experiments, material weathering aging, and spectral response testing and other scenarios. The sufficient ultraviolet band energy can efficiently excite photocatalytic materials to generate carriers; the rich near-infrared spectral output can meet the needs of photothermal collaborative experiments and full-band light response testing of solar cells.

During the complete usage life cycle, the spectral energy distribution is stable, without obvious color shift with the usage time, reducing the workload of spectral calibration after frequent replacement of lamps, ensuring the uniformity of spectral conditions between multiple batches of experiments, and improving the comparability and reproducibility of experimental data.

Durable quality craftsmanship, with an effective service life of over 800 hours

The lamp bulb adopts high-purity quartz bulb shell, special electrode materials, strict sealing process, able to withstand high-temperature and high-pressure conditions during the lighting process, with a nominal effective service life of ≥ 800 hours. Under reasonable heat dissipation and standard electrical drive conditions, it slows down electrode sputtering blackening, delays the rate of light flux attenuation, reduces the frequency of lamp replacement, and lowers the cost of consumables and maintenance. Compared with ordinary xenon lamps on the market, this product strictly controls the entire process of electrode processing, inflation, and packaging, reducing the probability of early failure. It is suitable for various working conditions such as continuous lighting in laboratories and intermittent operation of production line equipment.

Even when approaching the end of its lifespan, it still maintains the basic shape of the spectral profile and does not cause spectral distortion. This ensures that the experimental data during the approaching replacement cycle still has reference value and reduces the risk of sudden changes in experimental conditions before and after the expiration of consumables.

It is widely compatible in multiple scenarios and can be used for integrated equipment integration and spare parts replacement.

The 7XB-500-HTC spherical xenon lamp can be used as the core light-emitting unit and is widely compatible with 3A-level steady-state solar light simulators, photocatalytic xenon light sources, photoelectric material aging test systems, spectral response test systems, and surface photocurrent voltage test systems. It can be used for new equipment integrated matching, or as original replacement spare parts for the same specification equipment. The interface and electrical characteristics are matched, and after replacement, there is no need for significant changes to the optical path structure, reducing the time required for re-tuning. It is targeted at university laboratories, research institutions, and R&D and quality inspection departments of photovoltaic enterprises, covering research works such as photovoltaic cell calibration, water splitting photolysis, pollutant photodegradation, material photolysis, and biological light simulation.

The cable is led out in the HTC structure, suitable for wiring and installation of equipment in the light source room with compact internal space. It can work in a horizontal posture and is compatible with the magnetic stabilization structure inside the equipment, further suppressing arc flutter and further improving the output stability of the entire system.

Standardized components are provided for support, building a complete photonic light source ecosystem.

As a standardized light source component of Sefan Optoelectronics, the 7XB-500-HTC spherical xenon lamp can be coordinated with Sefan light source room, xenon lamp power supply, various filters, optical accessories, etc., to quickly build a complete light simulation system. It has passed lamp lighting screening and detection during factory production, eliminating substandard individuals with abnormal arcs and spectral deviations. Each bulb has controllable performance indicators and avoids the impact of single bulb quality defects on the performance of the entire system test. The manufacturer provides component selection technical support, installation, usage, and replacement precautions guidance to help users use the lamps in a standardized manner, fully leveraging the design lifespan of the lamps, and reducing the risk of damage caused by improper operation.

High-quality light source core, laying a solid foundation for precise light measurement experiments.

The bottom limit of a high-precision light simulation equipment depends on the quality of the xenon lamp itself. The 7XB-500-HTC spherical xenon lamp, relying on the characteristics of short arc point light source, daylight-level continuous spectrum, stable light color output, and reliable long-term lifespan, provides a reliable light-emitting core for solar light simulators, photocatalytic systems, and various photonic characterization equipment, helping photovoltaic calibration, photochemical research, and material photolysis and other scientific research and quality inspection work obtain stable and reproducible experimental data.
