Overview
The Atelass Xenon Arc Lamp Tube is a precision-engineered light source designed exclusively for xenon arc weathering test chambers used in accelerated material aging and photostability evaluation. Operating on the principle of broadband xenon arc discharge, this lamp replicates the full solar spectrum—from UV-B (290 nm) through visible to near-infrared—enabling physiologically and photochemically relevant exposure conditions. Unlike narrow-band UV fluorescent sources, xenon arc lamps provide spectrally continuous irradiation that closely matches terrestrial sunlight after appropriate optical filtration, making them the internationally preferred light source for ISO 4892-2, ASTM G155, and GB/T 16422-2 compliant testing. The lamp is integral to controlled environmental simulation where simultaneous exposure to light, heat, humidity, and water spray is required to assess colorfastness, gloss retention, polymer embrittlement, coating delamination, and photodegradation kinetics.
Key Features
- Full-spectrum xenon arc emission (300–1200 nm), calibrated to match CIE Standard Illuminant D65 after spectral filtering
- Forced-air cooling architecture ensures stable thermal management and extends operational lifetime
- Long-life optical filter compatibility—designed to maintain spectral output fidelity over extended irradiation cycles
- Modular lamp housing with standardized electrical and mechanical interfaces for rapid replacement (typical service time < 15 minutes)
- Rated for continuous or cyclic operation under programmable irradiance control (300–800 nm: 550 W/m² ±10%; 300–1200 nm: 1000 W/m² ±10%)
- Compliant with IEC 60068-2-5 and ISO 11341 for reproducible radiant exposure dosimetry
Sample Compatibility & Compliance
The lamp supports diverse specimen geometries via configurable sample holders—including flat mesh trays and rotating turntables (0–3 rpm)—accommodating textiles, automotive trim, architectural coatings, plastic composites, and outdoor signage substrates. Its integration into Atelass OK-XD series chambers (OK-XD-100 to OK-XD-1000) enables simultaneous control of black-panel temperature (40–85°C), chamber air temperature (0–150°C), relative humidity (20–98% RH), and programmed water spray (1–999 min cycles, 70–127 kPa pressure). All systems meet mandatory requirements for ISO 4892-2:2013, ASTM D529-22, GB/T 8427-2019, GB/T 14576-2015, and GB/T 15102–2006. Optional calibration traceability to NIST-traceable radiometers is available for GLP/GMP-regulated laboratories requiring audit-ready irradiance documentation.
Software & Data Management
When installed in Atelass OK-XD platforms, the lamp operates under embedded PID-controlled irradiance regulation synchronized with environmental parameters. Data logging includes real-time irradiance (W/m²), black-panel temperature, chamber RH, and cumulative radiant exposure (MJ/m²). Export formats support CSV and XML for integration with LIMS or quality management systems. Full audit trail functionality—including user access logs, parameter change history, and calibration event timestamps—meets FDA 21 CFR Part 11 requirements when configured with electronic signature modules. Remote monitoring via Ethernet/IP is supported for multi-site lab coordination.
Applications
This lamp tube is routinely deployed in QC/QA labs across textile dyeing houses (evaluating ISO 105-B02 colorfastness to light), automotive OEMs (validating SAE J2412 exterior trim durability), paint & coatings manufacturers (assessing ASTM D4587 QUV/xenon correlation), and R&D centers conducting polymer photostabilizer screening per ISO 11341. It is also specified in national standards for artificial leather (GB/T 15104–2006), laminated flooring (GB/T 15102–2006), and traffic signal materials (GB/T 8430–2019). Its spectral fidelity enables direct correlation between laboratory aging and real-world service life prediction models.
FAQ
What is the typical service life of this xenon lamp tube under standard test conditions?
Rated lifespan is approximately 1,600 hours at nominal irradiance (550 W/m², 300–800 nm band); actual endurance varies with operating setpoints, filtration configuration, and cooling efficiency.
Is spectral recalibration required after lamp replacement?
Yes—each new lamp must be paired with system-level radiometric calibration using a reference spectroradiometer to ensure compliance with ISO 4892-2 spectral power distribution tolerances.
Can this lamp be used in non-Atelass chambers?
Mechanical and electrical compatibility is chamber-specific; cross-platform use requires verification of socket type (e.g., U-shaped vs. straight-tube), ballast impedance, and cooling airflow specifications.
Does the lamp include integrated UV cutoff filtering?
No—the lamp itself emits broad-spectrum radiation; external optical filters (e.g., borosilicate inner/outer filters) are required to condition the output to match daylight or window-glass transmission profiles.
How is irradiance uniformity maintained across the test chamber workspace?
Uniformity (±10% across specimen plane) is achieved through optimized lamp geometry, reflector design, and rotational sample staging—not by the lamp alone—but as part of the complete OK-XD chamber system architecture.
