Introduction to Xenon Arc Aging Test Chambers

Xenon arc aging test chambers simulate the effects of sunlight, temperature, and moisture on materials, enabling accelerated aging studies for product durability assessment. The LISÚN XD-150LS Cámara de prueba para lámpara de xenón employs a water-cooled xenon arc lamp system to replicate full-spectrum solar radiation, providing precise control over irradiance, humidity, and temperature. This chamber is widely utilized in industries requiring rigorous environmental resistance validation, including automotive electronics, aerospace components, and consumer electronics.

Core Design and Operational Principles of the XD-150LS

The XD-150LS integrates a high-intensity xenon arc lamp with a water-cooling mechanism to maintain stable irradiance levels while preventing overheating. The spectral output closely mimics natural sunlight, including ultraviolet (UV), visible, and infrared (IR) wavelengths. A closed-loop feedback system adjusts lamp intensity in real time, ensuring compliance with international standards such as ISO 4892-2, ASTM G155, and IEC 61215.

Key operational components include:

• Xenon Arc Lamp: Emits a continuous spectrum from 290 nm to 800 nm.
• Water-Cooling System: Reduces thermal stress on the lamp, extending operational lifespan.
• Irradiance Control: Calibrated to ±0.1 W/m²/nm at 340 nm or 420 nm.
• Humidity Regulation: Adjustable from 10% to 98% RH.
• Gama de temperaturas: -10°C to +100°C (adjustable in 0.1°C increments).

Precision Irradiance Calibration and Spectral Fidelity

Accurate spectral distribution is critical for replicating real-world degradation effects. The XD-150LS utilizes a calibrated spectroradiometer to ensure wavelength-specific irradiance consistency. Unlike air-cooled systems, water-cooling minimizes spectral drift, maintaining stability over prolonged testing cycles.

For example, in electrónica del automóvil, prolonged UV exposure can degrade polymer housings and wire insulation. The XD-150LS replicates years of solar exposure in weeks, allowing manufacturers to assess material longevity before market deployment.

Advanced Humidity and Temperature Modulation

Many material failures result from combined solar radiation and moisture exposure. The XD-150LS integrates condensation and spray functions, enabling cyclic humidity testing per SAE J2527 (automotive weathering) and IEC 60068-2-5 (electronic component testing).

In equipos de telecomunicaciones, fiber-optic cables and connectors undergo accelerated hygrothermal aging to verify resistance to high-humidity environments. The chamber’s programmable cycles simulate diurnal temperature fluctuations, exposing latent material weaknesses.
