UV germicidal lamps kill bacteria and disinfect by emitting ultraviolet rays of specific wavelengths (mainly UVC band) to destroy the DNA structure of microorganisms, and are widely used in homes, hospitals, schools and other places. As a professional manufacturer of ultraviolet germicidal lamp tubes, LightBest Brand Company provides the following suggestions for the daily maintenance of UV germicidal lamps:

I. Preparation and Installation Before Use

1.Choose the Right Location

Avoid direct exposure to humans or pets, especially the eyes and skin, as UVC ultraviolet rays may cause burns or damage.

The recommended installation height is above 1.8 meters from the ground to ensure the irradiation range covers the target area (such as desktops and floors) while reducing the risk of human contact.

Avoid installation in humid, high-temperature or dust-prone environments to prevent the lamp tube from being damaged by moisture or overheating.

2. Check Equipment Integrity

Ensure the lamp tube is free of cracks and damage, and the quartz glass sleeve (if any) is transparent and free of stains, otherwise the ultraviolet penetration will be affected.

Check whether accessories such as ballasts and starters are intact to ensure stable circuit connection.

II. Precautions During Use

1. Control Usage Time and Frequency

Set a reasonable duration according to the space size and sterilization needs (usually 30 minutes to 1 hour each time), and avoid long-term continuous use to prevent the lamp tube from overheating or shortening its service life.

For home use, it is recommended to use 1-2 times a day for 30 minutes each time, and ensure it is turned on when no one is around.

2. Keep the Environment Clean

Regularly clean dust and stains on the surface of the lamp tube (with a soft cloth or alcohol cotton), and avoid blocking ultraviolet radiation.

Before cleaning, turn off the power and wait for the lamp tube to cool down to prevent scalding or electric shock.

3.Avoid Frequent Switching

The current is relatively large when the ultraviolet lamp tube starts. Frequent switching will accelerate the aging of the lamp tube and shorten its service life.

If it needs to be turned off temporarily, it is recommended to restart it after an interval of at least 10 minutes.

III. Regular Maintenance and Replacement

1. Record Usage Time

The service life of ultraviolet lamp tubes is usually 5000 hours (the standard model of ultraviolet germicidal lamp tubes produced by Changzhou Guangtai LightBest has an average service life of 9000 hours, and the ultraviolet amalgam lamp can be as long as 16000 hours). After exceeding the service life, the sterilization efficiency will decrease significantly.

It is recommended to record the first use time and replace the lamp tube in a timely manner when it expires.

2. Detect Ultraviolet Intensity

Regularly detect with an ultraviolet intensity meter (such as once every 3 months) to ensure the radiation intensity meets the standard (generally required to be ≥70μW/cm²).

If the intensity is insufficient, the lamp tube needs to be replaced even if it has not reached the service life.

3. Replace Accessories

When electronic components such as ballasts and starters are damaged, they must be replaced by professional personnel to avoid potential safety hazards caused by self-disassembly.

IV. Safety Protection Measures

1. Personal Protection

Close doors and windows when in use, and personnel leave the room to avoid direct exposure to ultraviolet rays.

If you need to enter temporarily, wear protective glasses and gloves, and long-sleeved clothing.

2. Safety for Children and Pets

Install the germicidal lamp at a height out of the reach of children, or use special equipment with a locked switch.

Prevent pets from entering the irradiation area to avoid eye or skin injuries.

3. Emergency Treatment

If accidentally exposed to ultraviolet rays, immediately rinse the affected area with cold water and seek medical examination.

If the lamp tube is found broken, turn off the power, wear gloves to clean up the fragments, and ventilate the room.

V. Precautions for Special Scenarios

1. Air Purifier Integrated Lamps

If the ultraviolet lamp is integrated into the air purifier, regularly clean the filter screen to avoid dust blockage affecting the sterilization effect.

Follow the product manual and replace the filter screen and lamp tube according to the recommended cycle.

2. Water Treatment Equipment

For UV lamps used in water treatment, regularly check the water flow rate and water quality to avoid scale blocking the quartz sleeve.

Before cleaning, turn off the water source and power supply to prevent electric shock or equipment damage.
