UV germicidal lamp: Structure and uses of UV lamp

Besides the bad sides, UV rays also have recognized good sides and since then, people have learned to take advantage of it to make devices with the ability to cure diseases from this type of ray. That was the birth of UV lamps.

2. Structure of germicidal UV lamp

By inventing materials that can emit light with the same wavelength as UV rays, this is called ultraviolet light.

Unlike fluorescent light bulbs, light tubes are made from regular glass while UV light tubes are made from high quality transparent quartz glass.

- The inside of the UV lamp's glass tube is coated with a layer of fluorescent powder like a regular light bulb and a little mercury vapor, inert gases and metal powders are added and is coated with a layer of barium - oxygen to help the lamp. creates colored light and increases durability at the two electrodes on each side of the lamp head.

- The spring-shaped filament (tungsten wire) is placed at the end of each lamp and is used to create an electric arc (at the ends of the two positive and negative electrodes of the lamp).

3. Uses of UV germicidal rays 

Normally, UV rays are often used in the medical and microbiology fields because they have the ability to inactivate the growth and development of bacteria and viruses, causing them to be destroyed (up to 99% kill ability). due to strong direct impact on bacterial nucleoprotein) and the light can last up to 800 - 1000 hours.

UV lamps are also used as corrective lamps for patients with vitamin D deficiency in the body, causing them to suffer from skin, bone, and other diseases...

Under our skin there are millions of pigment cells that help the body communicate with outside materials. The human body cannot synthesize vitamin D on its own, so sunlight helps us do this. Sunbathing for 10 - 15 minutes between 7 - 10 am or 3 - 4 pm is considered a good time to provide vitamin D to the body. This method can load our bodies with the recommended amount of vitamin D based on research from nutrition institutes around the world, which is 600 - 1000 IU/day for a 1 year old body. – 18 and from 800 – 1000 IU/day for adults.

In addition, this is also a way to destroy protozoa in water without having to buy disinfectant chemicals. Both high efficiency and cost savings (low energy consumption and long life).

When used to treat water, the UV lighting stage is placed last in the treatment system because if the water source is still turbid and has a lot of suspended sediment, the lighting will cover up a lot, leading to poor treatment efficiency. reduced and ineffective. Thereby, the water will not be guaranteed in terms of medical hygiene.

In current water filter systems, there is integrated UV light technology, so in treatment systems, filter cores containing UV lights are also widely used after Nano water filter membranes.

4. Note when using UV lamps

• Pay attention to the lamp's warranty policy
• Do not continue to use the water source when the lamp shows signs of damage
• Do not disassemble and install the lamp arbitrarily to avoid electric shock
