Water cooled xenon lamp tube

4.5KW/6.0KW/12KW water-cooled xenon lamp tube light sourceCommonly used for simulating the full sunlight spectrum (including ultraviolet, visible, and infrared bands) in weather resistance tests, the material selection is crucial for light output, stability, and lifespan. The following is the key information:

1、 Material type of lamp tube

1. Quartz glass tube

• Core advantages:
High transmittance: for ultraviolet light（UV）、 Visible light (VIS) and infrared light (IR) have good transmittance, especially suitable for full spectrum simulation.

High temperature resistance: With a low coefficient of thermal expansion (consistent with quartz characteristics), it can withstand the thermal stress when xenon lamps emit light at high temperatures.

Long lifespan: slow light decay, suitable for long-term continuous work and weather resistance testing.

• Structural features:
The lamp tube is fused silica tube with wall thickness of about1-2mm， Outer diameter of 8-12mm, length can reach several meters. Sealed tungsten electrodes at both ends and high-purity xenon gas (filled with gas), when energized, xenon gas ionizes to produce strong arc light, covering200-2500nm wide spectrum.

1. Spectral output

• Full spectrum coverage:
Main band:From 200nm (UV) to 2500nm (IR), the peak is concentrated in the visible light region (400-700 nm), which is close to the natural spectrum distribution of sunlight.

Can be filtered through optical filters (such as borosilicate glass, quartz)+Adjust the output with a metal film and eliminate unnecessary bands (such as removing<300nm ultraviolet to avoid excessive acceleration).

2. Application scenarios

• Material weather resistance test:
Aging assessment of sun sensitive materials such as automotive coatings, plastics, rubber, textiles, etc.

Quickly predict the outdoor service life of materials by simulating the combined effects of ultraviolet radiation, heat, and humidity.

• Scientific research and industrial testing:

Photovoltaic module UV attenuation resistance test, drug photostability test, evaluation of sunscreen effect of cosmetics, etc.

3、 Maintenance and Precautions

1. Light attenuation management:
The lifespan of xenon lamps is usuallyAfter 2000 hours, it is necessary to regularly calibrate the spectral output to avoid test result deviation caused by light attenuation.

2. Safe operation:
Strong light radiation should be equipped with protective devices to avoid direct contact with the lamp tube; Ensure that the cooling system is functioning properly during high-temperature operation.

3. Gas purity:
Xenon purity required≥ 99.9999%, impurities may cause unstable arc or premature failure of the lamp tube.
