Description

[Technical Field]

[0001] This invention relates to the technical field of a lamp tube, particularly to an ultraviolet lamp tube, and further to an air purifier comprising the ultraviolet lamp tube. [Previous Technology]

[0002] Specific wavelength light sterilization technology uses radiation sources to sterilize. It can be used on items that cannot be washed with detergent or water. It is widely used in industry or daily life because of its wide sterilization range, ease of use, few side effects and relatively low price.

[0003] Different wavelengths of light exhibit different bactericidal properties. For example, ultraviolet light with a wavelength of 185 nm can interact with air, decomposing oxygen (O2) into oxygen atoms (O), which then combine with oxygen in the air. The resulting product has a strong oxidizing effect, destroying and decomposing the cell walls of bacteria, thereby damaging their genetic material and preventing their metabolism and reproduction, leading to their death. This achieves the effects of removing mold, bacteria, and odors from the air. Ultraviolet light with a wavelength of 254 nm can directly act on the genetic material DNA of organisms within one second, causing new covalent bonds to form between adjacent thymine or cytosine bases, creating dimers. This change in DNA structure prevents the organism from forming proteins, thus losing its ability to divide and replicate, ultimately leading to death and achieving the purpose of sterilization. Ultraviolet light with a wavelength of 365 nm has a strong catalytic degradation function when titanium dioxide is irradiated. Through oxidation-reduction reaction, it can degrade harmful substances, bacteria and toxins released in the air, and finally dissipate into the air in the harmless form of water and carbon dioxide. Therefore, it is often used to remove formaldehyde, deodorize, resist stains and purify the air.

[0004] However, ultraviolet light can only travel in a straight line in the form of light, which results in blind spots in the sterilization effect. The products produced by the reaction of ultraviolet light with wavelength 185 nm with air can make up for this shortcoming. Therefore, ultraviolet lamps with wavelength 185 nm are used together with ultraviolet lamps of other wavelengths. However, using multiple lamps at the same time requires more space to place the lamps, which causes inconvenience in use.

[0005] In view of the different characteristics of various ultraviolet wavelengths, the best sterilization effect can be achieved by using ultraviolet rays of different wavelengths at the same time. In order to achieve the characteristics of convenient use and space saving, the inventor of the present invention has developed an ultraviolet lamp tube. This lamp tube can emit ultraviolet rays of three wavelengths at the same time in the form of a single lamp tube (such as a T5 type lamp tube) to achieve a wider sterilization effect. This lamp tube is applied in air purifiers and has greater industrial value.

[0006] In summary, the inventors of this invention have conceived and designed a method for manufacturing a multi-wavelength lamp tube and a multi-wavelength lamp tube, in order to improve upon the deficiencies of the prior art and thereby enhance its industrial application.

The present invention may be implemented in different forms and should not be construed as limited to the embodiments set forth herein. Rather, the embodiments provided will make this disclosure more thorough, complete and fully convey the scope of the invention to those skilled in the art. The present invention will be defined only by the appended claims.

[0044] It should be understood that although the terms "first," "second," etc., may be used in this invention to describe various elements, components, regions, sections, layers, and / or portions, these elements, components, regions, sections, layers, and / or portions should not be limited by these terms. These terms are only used to distinguish one element, component, region, section, layer, and / or portion from another element, component, region, section, layer, and / or portion.

[0045] Unless otherwise defined, all terms used in this invention (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and this invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly defined herein.

[0046] Please refer to Figure 1, which is a diagram of the first step of the manufacturing method of the multi-wavelength lamp tube of the present invention.

[0047] As shown in the figure, the manufacturing method of the multi-wavelength lamp tube of the present invention is preferably applied to cold cathode lamp tubes (CCFLs) so that a single lamp tube can emit light of multiple different wavelengths. The method includes the following steps: (S1) providing a plurality of light-transmitting portions on an inner surface of a tube body, wherein the plurality of light-transmitting portions are respectively allowed to transmit light of different wavelengths outside the tube body; (S2) providing a first electrode module at one end of the tube body, wherein a first electrode of the first electrode module is located inside the tube body; (S3) providing a filler in the tube body; and (S4) providing a second electrode module at the other end of the tube body, wherein a second electrode of the second electrode module is located inside the tube body.

[0048] The manufacturing method of the multi-wavelength lamp tube of the present invention utilizes the provision of a plurality of light-transmitting portions on the inner surface of the tube body, thereby enabling the multi-wavelength lamp tube manufactured by the manufacturing method of the present invention to emit multiple different wavelengths of light simultaneously, thereby achieving a wider and more effective sterilization effect while using the same lamp tube, and also saving the space required when it is applied to devices such as air purifiers.

[0049] Please refer to Figure 2, which is a diagram of the second step of the manufacturing method of the multi-wavelength lamp tube of the present invention. Furthermore, the light-transmitting part can be formed by coating methods such as sputtering and vacuum plating, or the light-transmitting part can also be formed by surface processing methods such as sandblasting and texturing.

[0050] Wherein, (S11) when the plurality of light-transmitting parts are formed by plating, the plurality of light-transmitting parts include a first light-transmitting part, a second light-transmitting part and a third light-transmitting part, the material of the first light-transmitting part 131 is TiO2, the material of the second light-transmitting part 132 is Al and TiO2, and the material of the third light-transmitting part 133 is Pt and TiO2.

[0051] Preferably, the thickness of the first light-transmitting part 131 is greater than or equal to 0.04 μm and less than or equal to 0.05 μm, the thickness of the second light-transmitting part 132 is greater than or equal to 0.02 μm and less than or equal to 0.03 μm, and the thickness of the third light-transmitting part 133 is greater than or equal to 0.005 μm and less than or equal to 0.01 μm.

[0052] Therefore, when light passes through the first light-transmitting part, it can emit short-wavelength light of 180nm; when light passes through the second light-transmitting part, it can emit medium-wavelength light of 250nm; and when light passes through the third light-transmitting part, it can emit long-wavelength light of 360nm. The first, second, and third light-transmitting parts are all disposed on the inner surface of the tube body, so that the multi-wavelength lamp can emit three wavelengths of light simultaneously.

[0053] In other words, the thicker the coating, the longer the wavelength that is transmitted, while the thinner the coating, the shorter the wavelength that is transmitted. Combined with the material of the coating, it can be ensured that the required wavelength can be emitted.

[0054] Wherein, (S12) when the plurality of light-transmitting portions are formed by surface processing, the plurality of light-transmitting portions 13 include a first light-transmitting portion, a second light-transmitting portion and a third light-transmitting portion, the depth of the first light-transmitting portion is greater than or equal to 0.005um and less than or equal to 0.01um, the depth of the second light-transmitting portion is greater than or equal to 0.02um and less than or equal to 0.03um, and the depth of the third light-transmitting portion is greater than or equal to 0.04um and less than or equal to 0.05um.

[0055] Therefore, when light passes through the first light-transmitting part, it can emit short-wavelength light of 180nm; when light passes through the second light-transmitting part, it can emit medium-wavelength light of 250nm; and when light passes through the third light-transmitting part, it can emit long-wavelength light of 360nm. The first, second, and third light-transmitting parts are all disposed on the inner surface of the tube body, so that the multi-wavelength lamp can emit three wavelengths of light simultaneously.

[0056] In other words, the thicker the tube wall, the longer the wavelength that is transmitted, while the thinner the tube wall, the shorter the wavelength that is transmitted. Therefore, this method can also ensure that the required wavelength can be emitted.

[0057] The thicker the surface layer, the longer the wavelength can penetrate; the thinner the surface layer, the shorter the wavelength can penetrate.

[0058] In practical applications, a fourth light-transmitting part or even a fifth light-transmitting part may be added, so the above illustrative examples should not be taken as a limitation.

[0059] Please refer to Figure 1 and Figure 3. Figure 3 is a schematic diagram of the first embodiment of the multi-wavelength lamp tube of the present invention.

[0060] Structurally, as shown in the figure, the multi-wavelength lamp tube 1 of the present invention can be a cold cathode fluorescent lamp (CCFL) and can be configured as a T5 type lamp tube for application environments or devices. The multi-wavelength lamp tube 1 of the present invention includes a tube body 10, a first electrode module 20, a second electrode module 30, and a filler 40. The tube body 10 can be made of glass or quartz glass, and it surrounds an accommodating space 12 via its inner surface 11. Both ends of the tube body 10 are open to accommodate components such as the first electrode module 20 and the second electrode module 30. The inner surface 11 of the tube body 10 has a plurality of light-transmitting portions 13, and each of the plurality of light-transmitting portions 13 allows light of different wavelengths to be transmitted out of the tube body 10. The first electrode module 20 is sealed at one end of the tube body 10, and the first electrode 21 of the first electrode module 20 is located in the accommodating space 12. The second electrode module 30 is sealed at the other end of the tube 10, and the second electrode 31 of the second electrode module 30 is located in the accommodating space 12. The filler 40 may be mercury or an inert gas, etc., and is disposed in the sealed accommodating space 12.

[0061] Incidentally, the first electrode module 20, the second electrode module 30, and the filler 40 are well known to those skilled in the art and will not be described in detail here. Furthermore, fluorescent powder or the like is also coated on the inner surface 11 of the tube body 10. Thus, when high voltage is input through the electrodes, a small number of electrons inside the tube collide with the electrodes at high speed, generating secondary emission and initiating discharge. Electrons collide with mercury atoms, thereby exciting ultraviolet light, which in turn excites the fluorescent powder to produce visible light of the corresponding color temperature. At this time, since the first, second, and third light-transmitting portions of the light-transmitting portion 13 are disposed on the inner surface 11 of the tube body 10, when light passes through the first light-transmitting portion, it emits short-wavelength light of 180nm; when light passes through the second light-transmitting portion, it emits medium-wavelength light of 250nm; and when light passes through the third light-transmitting portion, it emits long-wavelength light of 360nm.

[0062] The first, second and third light-transmitting parts of the light-transmitting part 13 are randomly distributed on the inner surface 11, so that the multi-wavelength lamp tube 1 can emit three wavelengths of light at the same time.

[0063] For example, when manufacturing the tube body, a first depth of recess can be formed on the inner surface of the tube body by sandblasting or the like to form a first light-transmitting part; then, a second depth of recess can be formed on the inner surface of the tube body by sandblasting or the like to form a second light-transmitting part; then, a third depth of recess can be formed on the inner surface of the tube body by sandblasting or the like to form a third light-transmitting part. Since the abrasive particles in the sandblasting process are randomly hit on the inner surface of the tube body, the first light-transmitting part, the second light-transmitting part, and the third light-transmitting part are randomly distributed on the inner surface 11.

[0064] Please refer to Figure 1 and Figure 4. Figure 4 is a schematic diagram of a second embodiment of the multi-wavelength lamp tube of the present invention. For detailed structural details, please refer to Figure 3.

[0065] As shown in the figure, the main difference between this embodiment and the previous embodiment is that the tube body 10 can be divided into multiple sections from one end to the other, and each light-transmitting part 13 is located on the inner surface 11 of each section.

[0066] For example, the tube body 10 can be sequentially configured into a first section, a second section, and a third section from the end having the first electrode module 20 to the end having the second electrode module 30. The first section may have a first light-transmitting portion 131 formed by plating or surface processing, the second section may have a second light-transmitting portion 132 formed by plating or surface processing, and the third section may have a third light-transmitting portion 133 formed by plating or surface processing. Therefore, the tube body 10 emits short-wavelength light of 180nm in the first section, medium-wavelength light of 250nm in the second section, and long-wavelength light of 360nm in the third section.

[0067] In summary, the manufacturing method and multi-wavelength lamp tube of the present invention utilize a specific tube structure configuration to combine ultraviolet lamp tubes with different bactericidal properties into a single lamp tube for use. The manufacturing method and multi-wavelength lamp tube of the present invention have the characteristics of saving space and have a wide bactericidal effect.

[0068] The above description is merely illustrative and not restrictive. Any equivalent modifications or alterations made without departing from the spirit and scope of this invention shall be included in the appended claims.
