Description

Technical Field

[0001] The present invention relates to a nanostructured light carrier, particularly utilizing nanoscale bumps or nanoscale recesses, or a combination thereof, on the surface of a nanostructure to interact with matter. When the light behavior reflects, transmits, resonates, or acts as a photocatalyst, or a combination of these behaviors, the nanostructure causes multiple light behaviors to enhance nanoreactions, significantly increasing the light intensity within the nanostructure, such as a nanoscale bump or nanoscale recess, as well as the light intensity between two adjacent nanoscale bumps, between two adjacent nanoscale recesses, and between two adjacent nanoscale bumps and recesses, thereby achieving the characteristics of killing bacteria or viruses and decomposing impurities. Background Art

[0002] In recent years, with the rapid progress and development of the economy, people have become increasingly concerned about improving the quality of life, especially in terms of lighting efficiency, ambient air quality, energy conservation and carbon reduction.

[0003] In terms of lighting, light-emitting diodes (LEDs) are the most common. However, traditional LED lamps can only consume 18-20W of power and have a total light output of only 1600-1800 lumens. In particular, the voltage range is only AC85-240.

[0004] In addition, ultraviolet (UV) lamps are commonly used to inhibit or kill bacteria. However, the ultraviolet light generated by traditional UV lamps is harmful to the human body and has a small irradiation range, so their application is very limited.

[0005] Negative ion purifiers that can continuously generate negative ions have a very small effective range and require regular cleaning, which consumes manpower. They are also prone to producing harmful ozone and are very slow in reducing PM2.5.

[0006] Therefore, there is a great need for an innovative nanostructured light carrier that utilizes the nano-bumps and nano-cavities on the nano-microstructure surface to perform multiple nano-reactions of light behavior, reflection, or resonance to significantly enhance the light intensity within the nano-bumps and nano-cavities, as well as the light intensity between two adjacent nano-bumps and between two adjacent nano-cavities, thereby achieving the characteristics of killing bacteria or viruses and decomposing impurities, thereby solving all the problems of the above-mentioned existing technologies. Summary of the Invention

[0007] The main purpose of the present invention is to provide a nanostructured optical carrier, comprising a nanoscale microstructured surface and a contact surface, wherein the nanostructure thickness of the nanoscale microstructured surface is approximately between 10 and 10,000 nanometers, and comprises one or more nanoscale bumps, or may further comprise one or more nanoscale recesses, and the contact surface is configured to contact the supporting surface of a substrate.

[0008] Taking a nanoscale microstructure surface including nanoscale bumps as an example, the nanoscale height of each nanoscale bump is between 1 and 1000 nanometers and is smaller than the thickness of the nanostructure, while the nanoscale width of each nanoscale bump is between 1 and 1000 nanometers, and the spacing between two adjacent nanoscale bumps is between 1 and 100,000 nanometers.

[0009] Specifically, the nanostructured optical carrier of the present invention is formed into a substrate through spraying, brushing, spin coating, immersion, deposition, growth, or etching, and has light reflectivity or transparency and is in the form of a thin sheet or film or a thin, discontinuous island with a nanostructure thickness, especially composed of at least one of aluminum, copper, nickel, iron, zinc, silver, gold, tin, cobalt, and titanium, that is, it is essentially a metal film, alloy film, or metal compound film.

[0010] The nano-scale bumps may include any one of rectangular cross-section convex or concave points, triangular pyramidal convex or concave points, cylindrical convex or concave points, and arc-shaped convex or concave points.

[0011] Regarding the light path, taking a nanoscale bump as an example, the first side of the nanoscale bump receives external incident light, generating external reflected light and internal transmitted light. The internal transmitted light is projected onto the second side of the nanoscale bump, generating internal reflected light and external transmitted light. The second side is opposite to the first side. The internal transmitted light and the internal reflected light resonate between the first and second sides of the nanoscale bump, thereby enhancing the light intensity between the first and second sides. Furthermore, the external transmitted light is projected onto the first side of an adjacent nanoscale bump, generating another external reflected light and another internal transmitted light. The other internal transmitted light is projected onto the second side of the adjacent nanoscale bump. The external transmitted light and the other external reflected light resonate between the first and second sides of the adjacent nanoscale bump, thereby enhancing the light intensity between the first and second sides of the adjacent nanoscale bump.

[0012] For the nanoscale recesses, the corresponding light paths are the same as the optical characteristics of the nanoscale bumps described above, and thus will not be described in detail.

[0013] Therefore, the light intensity within the nanoscale bumps and nanoscale recesses in the nanostructured optical carrier of the present invention, as well as the light intensity between two adjacent nanoscale bumps and two adjacent nanoscale recesses, will be greatly enhanced. This is equivalent to strengthening the function of the photo-nano reaction to store energy, or release light energy under appropriate conditions, and has the characteristics of killing bacteria or viruses and decomposing impurities.

[0043] The following is a more detailed description of the embodiments of the present invention with reference to icons and component symbols, so that those skilled in the art can implement the embodiments accordingly after studying this specification.

[0044] Please refer to Figure 1 , a schematic diagram of a nanostructured light carrier according to an embodiment of the present invention. Figure 1 As shown, the nanostructured optical carrier 1 of an embodiment of the present invention includes a nanostructured surface 10 and a contact surface 20. The nanostructured surface 10 has a nanostructure thickness T between 10 and 10,000 nanometers and includes one or more nanostructured bumps 11, each of which is spaced apart from the other. Furthermore, the nanostructured surface 10 may also include one or more nanostructured recesses 12. However, for ease of illustration, the nanostructured surface 10 is used as an example, and the figure primarily illustrates all geometric features of the nanostructured bump 11, while only a partial view of the nanostructured recess 12 is shown. In other words, the technical features of the nanostructured bump 11 also apply to the nanostructured recess 12, except that the geometric features in the vertical direction are reversed. That is, the protruding areas of the nanostructured bump 11 are replaced by the recessed areas of the nanostructured recess 12. Furthermore, each of the nanoscale recesses 12 is spaced apart from each other, and each of the nanoscale recesses 12 and each of the nanoscale bumps 11 are also spaced apart from each other.

[0045] Furthermore, the contact surface 20 is configured to contact the supporting surface of the substrate 2. In particular, the enlarged region A in the figure shows the nanoscale height H and nanoscale width W of the nanoscale bumps 11. The nanoscale height H of each nanoscale bump 11 is between 1 and 1000 nanometers and is less than the thickness T of the nanostructure. The nanoscale width W of each nanoscale bump 11 is between 1 and 1000 nanometers, and the spacing D between two adjacent nanoscale bumps 11 is between 1 and 100,000 nanometers.

[0046] Generally speaking, the nanostructured optical carrier 1 is formed on the substrate 2 via a spraying process, an immersion process, a deposition process, an etching process, or an etching process. The nanostructured optical carrier 1 is light reflective or transmissive and is in the form of a thin sheet, a film, or a thin, discontinuous island with a nanostructure thickness. It is composed of at least one of aluminum, copper, nickel, iron, zinc, silver, gold, tin, cobalt, and titanium. In other words, the nanostructured optical carrier 1 is essentially a metal layer or an alloy layer. However, the nanostructure thickness T of the nanoscale microstructure surface 10 is quite small, so it also has light transmissivity.

[0047] The above-mentioned spraying process includes first spraying the spray slurry onto the contact surface 20 by spraying to form a spray layer, and then allowing it to dry naturally or undergo a drying process to form the nanostructured light carrier 1 of the present invention on the contact surface 20, wherein the spray slurry includes at least one of aluminum, copper, nickel, iron, zinc, silver, gold, tin, cobalt and titanium and a carrier liquid, and the carrier liquid is at least one of deionized water, methanol, ethanol and acetone. In particular, the drying process is used to remove the carrier liquid, and the temperature of the drying process is higher than the boiling point of the carrier liquid.

[0048] In addition, the immersion treatment includes first immersing the immersion slurry to form an immersion layer on the contact surface 20, and then allowing it to dry naturally or undergo a drying treatment to form the nanostructured optical carrier 1 on the contact surface 20, wherein the immersion slurry includes at least one of aluminum, copper, nickel, iron, zinc, silver and gold and a carrier liquid, and the carrier liquid includes at least one of deionized water, methanol, ethanol and acetone. In particular, the drying treatment is used to remove the carrier liquid, and the drying treatment temperature is higher than the boiling point of the carrier liquid.

[0049] Furthermore, the deposition process includes physical or chemical deposition process.

[0050] Furthermore, the nano-scale bumps 11 may include one of rectangular cross-section bumps, triangular pyramidal bumps, cylindrical bumps, and arc-shaped bumps, but the present invention is not limited thereto, so nano-scale bumps 11 of other different shapes should also be included in the scope of the present invention. For example, Figure 3 Another schematic diagram of a nanostructured light carrier according to an embodiment of the present invention is shown, wherein the nanoscale microstructure surface 10 includes a plurality of rectangular cross-section bumps, a plurality of triangular pyramidal bumps, a plurality of cylindrical bumps, and a plurality of arc-shaped bumps, serving as bump nanoscale bumps 11. Furthermore, the spacing D between two adjacent nanoscale bumps 11 is not a fixed value, but varies within a preset range. Similarly, the nanoscale height H and nanoscale width W also vary within a preset range and are not fixed values, as can be clearly seen in the locally enlarged area B.

[0051] The above-mentioned substrate 2 is light-transmissive or reflective to visible light, such as the lampshade of a light-emitting diode (LED) lamp, a car windshield, a window glass panel or a solar panel. For example, the nanostructured light carrier 1 of the present invention can be used to enhance the emitted light of the lamp. Alternatively, the substrate 2 is light-reflective to visible light, such as the reflective plate of a lamp, the exterior wall materials of a building, or the body of a car, and the bearing surface in contact with the contact surface 20 is used as a light reflecting surface, and the nanostructured light carrier 1 of the present invention can be used to enhance the reflected light of the reflective plate, for example, the emitted light of the lamp can be enhanced.

[0052] Referring further to FIG. 2 , a schematic diagram of the optical path of a nanostructured light carrier according to an embodiment of the present invention is shown. As shown in FIG. 2 , a first side surface S1 (e.g., the left side) of the nanoscale bump 11 receives external incident light L1, generating external reflected light L2 and internal transmitted light L3. The internal transmitted light L3 is further projected onto a second side surface S2 (e.g., the right side) of the nanoscale bump 11. That is, the second side surface S2 is opposite to the first side surface S1, thereby generating internal reflected light L4 and external transmitted light L5.

[0053] It should be noted that the internal transmitted light L3 and the internal reflected light L4 form a reflection or resonance effect between the first side surface S1 and the second side surface S2 of the nanoscale bump 11, thereby enhancing the light intensity between the first side surface S1 and the second side surface S2.

[0054] Furthermore, the externally transmitted light L5 is further projected onto the first side surface S11 of the adjacent nanoscale bump 11, generating another externally reflected light L6 and another internally transmitted light L7. Similarly, the other internally transmitted light L7 is projected onto the second side surface S22 of the adjacent nanoscale bump 11, generating another internally reflected light L8 and another externally transmitted light L9. Clearly, the externally transmitted light L5 and the other externally reflected light L6 reflect or resonate in the free space between two adjacent nanoscale bumps 11, thereby enhancing the light intensity. Similarly, the other internally transmitted light L7 and the other internally reflected light L8 reflect or resonate within the adjacent nanoscale bump 11, and so on.

[0055] In short, the light within the nanoscale bump 11 of the present invention and the light between two adjacent nanoscale bumps 11 will produce reflection or resonance, or what is called multiple reflection, similar to a resonant cavity. Therefore, the light intensity within the nanoscale bump 11 of the present invention and the light intensity between two adjacent nanoscale bumps 11 are greatly enhanced, which is equivalent to a nanoreaction and has the function of accumulating or stimulating energy, and has the characteristics of killing bacteria or viruses and decomposing impurities.

[0056] In particular, since reflection or resonance requires that the length of the resonant cavity be an integer multiple of half a wavelength, reflection or resonance occurs when the nanoscale width W of the nanoscale bumps 11 of the present invention is an integer multiple of half a wavelength. Furthermore, reflection or resonance also occurs when the spacing D between two adjacent nanoscale bumps 11 is an integer multiple of half a wavelength. In other words, reflection or resonance can be achieved by adjusting the nanoscale width W and spacing D of the nanoscale microstructure surface 10, thereby enhancing light intensity by selecting light wavelength.

[0057] When the nanoscale width W of the nanoscale bump 11 of the present invention is less than half the wavelength, the quantum effect of the nanoscale bump will dominate, and the nanoscale bump will enhance the surface plasmon effect of light, thereby increasing light efficiency.

[0058] Furthermore, the nano-scale microstructure surface 10 of the present invention can also enhance the mechanical structural strength of the entire nano-structured optical carrier 1 to prevent damage such as breakage or cracking.

[0059] In terms of application, substrate 2 can be a car windshield. The nanostructured light carrier 1 of the present invention, when mounted on a car windshield, can inhibit bacteria, deodorize, decompose organic compounds, and purify the air, significantly improving sanitation for vehicles frequently exposed to polluted air while driving on the road. Furthermore, by transmitting sunlight, it can produce the same enhanced light intensity effect as LED light, effectively improving the interior environment of vehicles such as sightseeing buses, minibuses, and taxis.

[0060] Taking LED tubes and LED lamps as an example, the present invention inhibits bacteria, is harmless to the human body, and continuously produces trace amounts of negative ions that are beneficial to the human body. In particular, it does not produce harmful ultraviolet (UV) light or ozone. Furthermore, it has a wide illumination range, requires no regular cleaning, and can quickly reduce PM2.5. In contrast, while traditional UV lamps can inhibit bacteria, they are harmful to the human body and have a narrow illumination range. Negative ion purifiers that continuously generate negative ions have a very small effective range, require labor-intensive regular cleaning, and are prone to producing harmful ozone. Their PM2.5 reduction rate is also quite slow.

[0061] When applied to LED lamps, the nanostructured light carriers of this invention are more energy-efficient, brighter, and less susceptible to light decay than conventional LED lamps. They also maintain a lower temperature, achieving the goal of producing low-blue-light LEDs while offering a higher voltage tolerance. Specifically, the LED lamps of this invention achieve a power consumption of 15.8W, a total light output of 2000 lumens, and a voltage tolerance of AC85-277, compared to conventional LED lamps, which only offer power consumption of 18-20W, a total light output of 1600-1800 lumens, and a voltage tolerance of AC85-240.

[0062] Furthermore, traditional air purifiers consume a lot of electricity and require regular cleaning / filter replacement, which consumes valuable manpower and is particularly expensive. Products utilizing the nanostructured light carriers of the present invention can achieve the same efficacy, particularly by decomposing organic compounds in the environment, removing odors and purifying the air. These products are harmless to the human body and do not require cleaning or filter replacement, nor do they require any consumables.

[0063] In summary, the present invention is characterized by utilizing the nanoscale bumps and nanoscale recesses on the nanoscale microstructure surface to perform multiple nanoscale reactions involving light behavior, reflection, or resonance, thereby significantly enhancing the light intensity within the nanoscale bumps and nanoscale recesses, as well as the light intensity between two adjacent nanoscale bumps and nanoscale recesses, and between two adjacent nanoscale recesses, thereby achieving the effect of killing bacteria and viruses and decomposing impurities.

[0064] The above description is only used to explain the preferred embodiments of the present invention and is not intended to limit the present invention in any form. Therefore, any modifications or changes made to the present invention under the same inventive spirit should still be included in the scope of protection intended by the present invention.
