Notes on the Internal Light Source of Xenon Lamp Aging Test Chamber

Views: 0     Author: Site Editor     Publish Time: 2023-12-15      Origin: Site

The internal light source of the xenon lamp aging test chamber is a photochemical xenon lamp used for illumination. The spectrum contains characteristics of ultraviolet, visible, and near-infrared spectra, similar to the solar spectrum, and is widely used as a solar simulator. Featuring high power and wide spectral output, it can be used for absorption and fluorescence excitation, with a spectral range of over 260nm and no ozone.

Xenon lamps have been widely used in fields such as photocatalytic hydrogen production, photodegradation of pollutants, various simulated sunlight visible light acceleration experiments, and various simulated sunlight ultraviolet band acceleration experiments.

Xenon lamps can achieve online and offline analysis experiments for solid, liquid, and gas phases. According to the structure of the light bulb, it can be divided into long arc xenon lamps, short arc xenon lamps, and spherical xenon lamps. According to the different irradiation methods, it can be divided into internal and external types. Long arc xenon lamps generally use tubular xenon lamps placed in xenon lamp aging test chambers, with internal light scattered around. This form of light source is called internal illumination light source. This type of light source belongs to full band illumination and cannot be filtered, but it is cheap and suitable for primary research in photochemistry.

Precautions for internal xenon lamps during xenon lamp aging test chamber

1. The back end of the light bulb is sharp and protruding, which is relatively fragile. It is strictly prohibited to hit this area.

2. Before starting up and when the light source is running, it is necessary to ensure that the fan is in

 working condition. If the fan malfunctions, it is strictly prohibited to start up.

3. During operation, movement is prohibited.

4. When using a light source, be sure not to look directly at the light outlet. If there are spots, be sure to wear protective glasses.

5. When using xenon lamps, do not touch the surface of the radiator and filter to avoid burns.

6. Pay attention to the cleanliness of the work environment to prevent small items from falling from the scattered holes above the lightbox.

7. The working current must not exceed 21AMP (amperes).

8. When the high-voltage module fails to excite the bulb multiple times (about 10 times) and causes it to light up, do not continue to try, replace the bulb immediately.

Above 8 points, operators should always pay attention to avoid safety accidents that may harm themselves.
