Factors affecting the light intensity reduction of deuterium lamp;

1. Evaporation of internal metal parts and paint of the deuterium lamp;

2. The filament coating material of the deuterium lamp reacts with the Shi Ying sleeve;

3. Sunlight will cause the Shi Ying sleeve to absorb light with the wavelength of 200-250 nm.

When the service life of deuterium lamp is approaching, the light intensity emitted by deuterium lamp will decay quickly until it can't be lit. If the lighting fails all the time, it is a signal that there is something wrong with the deuterium lamp.

Causes of shortening the service life of deuterium lamp;

1. Switching frequency of deuterium lamp

The switching times of deuterium lamp are inversely proportional to its normal service time.

Suggestion: It is best to turn off the lights for more than 4 hours. For working 8 hours a day, if you don't turn off the lights during this period, the life of your deuterium lamp will be reduced by 30%. Switching the deuterium lamp on and off frequently at rest every day will also damage the life of the deuterium lamp and may affect the production efficiency, because it takes about 30 minutes to stabilize after the deuterium lamp is lit.

2. The jacket of deuterium lamp is defiled.

Do not touch the deuterium lamp directly with your hands. Oily substances contained in hands will leave a stain on Shi Ying's coat, which will hinder the light emitted by the light source of deuterium lamp. If you accidentally touch the deuterium lamp directly by hand, please clean the deuterium lamp with isopropanol before installing it.
