Description

Cold cathode tube ozone lamp

Technical Field

The present application relates to a cold cathode tube ozone lamp, and more particularly to an ozone lamp using a plurality of lamps connected in series and in parallel.

Background

Since 1801 years, ultraviolet rays have been discovered and widely and generally applied after two hundred years of research, development and experiments, and the ultraviolet rays have proved to have extremely good disinfection and sterilization effects, and ultraviolet disinfection lamps are widely applied to medical use and are the best method for disinfecting and sterilizing infectious viruses.

Generally, the ultraviolet light is divided into three wavelengths, namely, a long wavelength (UV-A), a medium wavelength (UV-B) and a short wavelength (UV-C), wherein the wavelengths are UVA (340-:

UVA: the wavelength is longer, the wavelength is between 340 and 400nm, can penetrate through cloud layer and glass into the room and the vehicle, UVA can penetrate through the dermis layer of the skin, and people can be suntanned, wherein UVA can be further divided into UVA-2(340 and 340nm) and UVA-1(340 and 400 nm).

UVB: the wavelength is intermediate, the wavelength is between 280-340nm, and the ozone layer can absorb the light, and the light can cause sunburn and red, swollen, hot and painful skin, and the serious one can also cause blister or desquamation.

UVC: the wavelength is between 100-280nm, but since the wavelength below 200nm is vacuum ultraviolet wavelength, it can be absorbed by air, so the wavelength of UVC passing through the atmosphere is between 200-280nm, the shorter the UVC wavelength, the more dangerous, but only a small amount will reach the earth surface because it can be blocked by the ozone layer.

The UVC wavelengths mentioned above can be further subdivided into:

ultraviolet rays in the range of 250nm to 270 nm: has effects in destroying single bacteria, viruses, fungi, and yeast.

Wavelength less than 200 nm: ozone is generated from oxygen in the air, and when the ozone contacts with organic compounds, the ozone is rapidly decomposed and oxidizes the organic compounds.

At present, ozone is widely used in air cleaning devices or sterilization equipment, and the generation of artificial ozone can be roughly divided into high-voltage discharge generation and ultraviolet light generation. In the devices used by the people, namely the ozone lamp device.

The ozone lamp can be simply divided into a hot cathode tube (also called a hot cathode ultraviolet lamp tube) and a cold cathode tube, wherein the hot cathode tube is excited by electrons sent by a hot filament, the output power of the hot cathode tube is high, but the operating temperature of the hot cathode tube is quite limited and the hot cathode tube cannot be started at a low temperature below zero; the cold cathode tube is excited by current drive, the output power is lower than that of the hot cathode tube, the ozone generation amount is also lower, but the cold cathode tube can be used below zero.

In the sterilization system and apparatus, the hot cathode ultraviolet lamp is a commonly used ultraviolet lamp, but cannot be widely used in outdoor spaces such as cars, ambulances, and relatively ventilated factories due to the above-mentioned operating temperature limitation. The cold cathode tube is not started by a hot filament, so that the sterilization system or device in the industry is gradually developed towards using the cold cathode tube, but the cold cathode tube is not started by a hot filament, so that the cold cathode tube cannot be applied to a larger sterilization system in a high-power mode.
