At the same time, mercury in such light sources can also cause environmental pollution. With the progress of science and technology, people find that the ultraviolet ray with the wavelength of 222 nanometers can play a role in disinfection and sterilization, and meanwhile, the ultraviolet ray with the wavelength cannot cause damage to human bodies or animals. However, to date, there is no commercially available ultraviolet lamp that produces ultraviolet light at a wavelength of 222 nanometers for sterilization and disinfection.

When the device is used, a power supply which outputs high frequency (10-50 KHZ) and high voltage (more than 1000V) is applied to the two strip-shaped electrodes through the lead-out wires, under the action of the high voltage and the high frequency electricity, gas between the two strip-shaped electrodes is ionized by a high-voltage electric field to generate a glow effect so as to excite ultraviolet rays with the central wavelength of 222 nanometers, and the ultraviolet rays are radiated through other parts of the closed quartz glass tube with the narrow-frequency filtering function except the strip-shaped electrodes and act on places needing sterilization and disinfection. The strip electrodes distributed along the length of the quartz glass tube are adopted to ensure that the gas in the quartz glass tube can be ionized by a high-voltage electric field and generate enough ultraviolet rays of 222 nanometers.

And an insulating protective layer is adopted to prevent the strip-shaped electrode from being exposed outside to cause accidents such as electric shock and the like.
An ultraviolet lamp comprises a lamp holder, an ultraviolet light source arranged on the lamp holder, a light-transmitting protective cover arranged on the lamp holder, and a power supply arranged in the lamp holder and capable of generating high frequency and high voltage.
When in use, the power supply which can generate high frequency and high voltage is communicated with the commercial power, and the electrified ultraviolet light source emits ultraviolet rays with the wavelength of 222 nanometers, and the ultraviolet rays penetrate through the light-transmitting protective cover to act on the place needing sterilization and disinfection. The lamp holder and the light-transmitting protective cover are adopted, so that the ultraviolet lamp can be placed at a required position as required and then can be used by connecting with a mains supply, and therefore, the use is very convenient.
Here, the light-transmissive shield includes a grid surrounding the ultraviolet light source, a cover on top of the grid. The grid is adopted, so that ultraviolet light is transmitted out without obstruction, meanwhile, a user touches the exposed strip-shaped electrodes on the ultraviolet light source, and the cover is used for positioning the ceramic sleeve at the top of the ultraviolet light source, so that the ultraviolet light source is stably positioned in the middle of the light-transmitting protective cover.
