Product Name: Low Pressure Mercury UV Lamp

Developed on the basis of the high-pressure mercury lamp, this type of lamp is made of a high-purity quartz tube filled with mercury, argon and gallium iodides, iron iodides and halides of some rare metals. There are too many empty spots in the spectrum around the 365 nm wavelength.

The use of elements whose emission spectrum is in this wavelength range provides high vapor pressure at a certain temperature, creates dense light spectra in this wavelength range, increases the efficiency of UV radiation in this wavelength range by 1–2 times, and then increases the efficiency of electrical energy and the curing rate during operation.

Gallium iodide can introduce 403nm and 417nm spectral lines into the low-pressure UV spectrum, which is widely used in the processing of nitrogen compounds; Iron iodide is a halogen which can provide broad-spectrum UV and increase the output power of the lamp in the spectrum of 380nm. Low-pressure UV with the addition of iron iodide can provide good effects in the exposure system of photopolymers and sunlight photographic films.

The energy of the low pressure ultraviolet spectrum can match the adsorption spectrum of some materials very well and can cause a curing reaction very quickly.

Additional information about the devices:

Low-pressure UV lamps, also known as LPD (Low-Pressure UV lamps), are a type of UV lamp that are used in various applications to disinfect water, air, surfaces, and other environments. Here is more information about them:

Operating principle : Low-pressure UV lamps operate on the basis of the phenomenon of photochemical reaction, when ultraviolet radiation of a certain wavelength (usually 254 nm) is absorbed by the DNA or RNA of microorganisms, which leads to their destruction or neutralization. The UV radiation of the lamp causes a photochemical reaction in the DNA or RNA of bacteria, viruses, fungi and other pathogens, which makes them incapable of reproduction.
애플리케이션 : Low pressure ultraviolet lamps are widely used in water treatment for disinfection of drinking water, disinfection of water in swimming pools and spas, sterilization of medical instruments and equipment, processing of food and beverages, and in ventilation and air conditioning systems for the destruction of bacteria and fungi.
Structure : UV lamps typically have a quartz or glass tube filled with an inert gas such as argon or xenon. The inner wall of the tube is coated with phosphorus, which converts ultraviolet radiation into visible light, making the lamp bright. Electrodes, usually made of tungsten, are located at the ends of the tube and serve to supply the electric current.
Advantages : Low pressure ultraviolet lamps have a number of advantages, including high disinfection efficiency, no need for chemical additives, non-toxic and environmentally friendly, and no odor or taste in treated water environments.
Limitations and Cautions : It is important to note that low-pressure UV lamps are only effective when directly irradiating surfaces or environments, so it is important to ensure that the lamps are positioned correctly and that sufficient irradiation time is provided to achieve the required disinfection. It should also be remembered that UV radiation can be harmful to the eyes and skin, so precautions must be taken when working with these lamps.
