Embodiment 1

[0024] Embodiment 1: as figure 1 As shown, the present invention includes a closed quartz glass tube 1 filled with gas (which may be a mixture of multiple inert gases), and strips that are closely attached to the opposite sides of the quartz glass tube 1 and distributed along the length of the closed quartz glass tube 1. Shaped electrode 2, a power supply 3 capable of generating high frequency of 10-50KHZ and high voltage above 1000V, the two power output terminals of the power supply 3 are respectively connected with the strip electrodes 2 on opposite sides of the closed quartz glass tube 1, the gas is heated by high voltage Electric field ionization can generate ultraviolet gas with a center wavelength of 222 nanometers. An insulating protective layer 4 that only covers the strip electrodes 2 is provided outside the strip electrodes of the closed quartz glass tube 1 .

[0025] The end of the closed quartz glass tube 1 is provided with a pressure-resistant and high-temperatur...

Embodiment 2

[0028] Embodiment 2: as figure 2 As shown, this embodiment is based on Embodiment 1, and the insulating protective layer 4 is a quartz glass sleeve sleeved on the closed quartz glass tube 1 .

Embodiment 3

[0029] Embodiment 3: as image 3 As shown, the present embodiment is on the basis of embodiment 1, several closed quartz glass tubes 1 equipped with gas that can produce ultraviolet rays with a center wavelength of 222 nanometers after being ionized by a high-voltage electric field are placed side by side to form a closed The quartz glass tube group a, the strip electrodes 2 are arranged on the left and right sides of the quartz glass tube group a, the front and rear sides of the quartz glass tube group a are ultraviolet emitting surfaces, so that the high voltage electric field formed between the strip electrodes 2 acts on the All the gases in the closed quartz glass tubes 1 are ionized, and the ultraviolet rays with a center wavelength of 222 nanometers are emitted from the front and rear sides of the quartz glass tube group a.

Abstract

The invention provides an ultraviolet lamp. The ultraviolet lamp is characterized by comprising a closed quartz glass tube filled with gas, strip-shaped electrodes arranged on two opposite sides of the quartz glass tube and distributed along the body length of the closed quartz glass tube, and a power supply capable of generating high frequency and high voltage, wherein the two power output ends of the power supply are connected with the strip-shaped electrodes on the two opposite sides of the closed quartz glass tube respectively, and gas can generate ultraviolet rays with a center wavelength of 222 nanometers after being ionized by a high-voltage electric field. Compared with the prior art, the ultraviolet lamp of the invention has the advantage of being capable of stably generating ultraviolet rays which are used for sterilization and disinfection, do not cause harm to human bodies or animals and have the central wavelength of 222 nanometers.

Description

technical field [0001] The invention relates to an electric light source technology. Background technique [0002] At present, among the commonly used ultraviolet lamp tubes, the gas discharge light sources that can emit ultraviolet rays with a wavelength of 253.7 nanometers all use hot cathode filaments or cold cathode filaments. The lamp tube must be filled with an appropriate amount of mercury to work normally. Although it can play a role in sterilization and disinfection, if the ultraviolet rays with a wavelength of 253.7 nanometers are directly irradiated to the human body or animals, it will cause great harm to the human body or animals. At the same time, mercury in such light sources will also pollute the environment. With the advancement of science and technology, through in-depth research, people have found that ultraviolet rays with a wavelength of 222 nanometers can also play a role in disinfection and sterilization, and at the same time, ultraviolet rays with th...
