What Is a Germicidal Bulb?

The germicidal lamp is actually a low-pressure mercury lamp. The low-pressure mercury lamp emits ultraviolet light by being stimulated with a lower mercury vapor pressure (<10-2Pa). There are two main spectral lines: one is the 253.7nm wavelength; the other is the 185nm wavelength, both of which are naked eyes. Invisible UV.

Since ultraviolet rays can kill cells, care must be taken not to directly expose them during UV disinfection.

Ultraviolet disinfection is widely used in hospitals, schools, nurseries, movie theaters, buses, offices, homes, etc. It can purify the air and eliminate moldy odors. It can also generate a certain amount of negative oxygen ions outside the room. The air is particularly fresh. In public places, disinfection by UV can prevent some germs from spreading through the air or the surface of objects. The application of long-life UV germicidal lamps in water disinfection and environmental protection projects is of great significance. Water disinfection equipment such as pure water systems generally operate for 24 hours. The life and reliability of UV germicidal lamps are high. If the lamp life is short Replacement of the lamp is costly and inconvenient.

With the change of the market and the increase of customers' requirements for products, all UV lamp manufacturers are developing long-life lamps. The cold cathode series of UV lamps are developed with 4, 5, 6, 10, and 12 mm outer diameters. To replace the hot cathode series of UV lamps.
