Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present application is not limited to the specific embodiments disclosed below.
Next, the present application will be described in detail with reference to the schematic drawings, wherein the cross-sectional views of the device structure are not to scale for the sake of illustration, and the schematic drawings are merely examples, which should not limit the scope of protection of the present application. In addition, the three-dimensional dimensions of length, width and depth should be included in actual fabrication.
As described in the background section, how to collect a light beam with high energy density at a receiving end of long-distance wireless energy transmission is a technical problem to be solved by those skilled in the art.
If the light beam with high energy density is converted into heat energy at the receiving end of long-distance wireless energy transmission, the conversion efficiency is low, the light beam is converted into electric energy in the next step, and the conversion from heat energy to electric energy is needed, so that the energy conversion form is too complex, and therefore, the light beam with high energy density is more prone to be directly converted into electric energy through the photoelectric device at the receiving end of long-distance wireless energy transmission, but the photoelectric device cannot normally bear the light beam with high energy density, otherwise, the photoelectric device is damaged.
In view of this, the embodiment of the present application provides a light-passing structure, fig. 1 shows a schematic diagram of the light-passing structure provided in the embodiment of the present application, and as shown in fig. 1, the light-passing structure includes:
a quartz body 10 extending in a first direction X, the quartz body 10 having a first end 11 and a second end 12 disposed opposite in the first direction X, the first end 11 of the quartz body 10 receiving a light beam transmitted in the first direction X;
the light-diffusing material 20 distributed in the quartz body 10, the refractive index of the light-diffusing material 20 being different from that of the quartz body 10, causes the light beam incident into the quartz body 10 to be reflected or scattered by the light-diffusing material 20 toward the side wall of the quartz body and to be emitted from the side wall of the quartz body 10.
In the embodiment of the present application, the quartz body 10 is located on the transmission path of the light beam, and the first end 11 of the quartz body 10 receives the light beam transmitted along the first direction X, specifically, as shown by the solid line with arrow on the left side of the first end 11 of the quartz body 10 in fig. 1, the light beam may be a light beam with high energy density for long distance wireless energy transmission.
Optionally, the light beam may be a laser beam, where the laser beam may be a laser beam of 500nm, 808nm or 1060nm, and the laser beam is emitted from a single light source (such as a laser source) with advantages of uniformity, concealment (non-visible light), low divergence, and low thermal effect; alternatively, the light beam may be a concentrated solar beam, and in this case, the light source may be a lens with a light concentrating effect.
In view of the requirement that the light flux of high energy density is incident on the light-passing structure, the light-passing structure body is resistant to high temperature, high energy and damage, and therefore, in the embodiment of the present application, the quartz body 10 is resistant to high temperature, high energy and damage is used as the light-passing structure body.
In practical application, the light-passing structure provided by the embodiment of the application can be prepared by adopting a hot melting method. Specifically, the light diffusing material 20 is doped into the quartz melt while the quartz is hot melted, and then shaped to form a light-passing structure. However, the present application is not limited thereto, and the light diffusing material 20 may be doped in the quartz body 10 by an electrofusion method, a gas-fusion method, a chemical vapor deposition synthesis method, an in-situ doping method, a co-growth method, or the like to form a light-passing structure.
The light flux structure provided in this embodiment of the present application may be applied to a receiving end of long-distance wireless energy transmission, because the light scattering material 20 is distributed in the quartz main body 10, and the refractive index of the light scattering material 20 is different from that of the quartz main body 10, the light scattering material 20 in the quartz main body 10 may be used as a reflection or scattering center, so that the light beam incident into the quartz main body 10 is reflected or scattered by the light scattering material 20 toward the side wall of the quartz main body, i.e., the light beam incident into the quartz main body 10 is effectively dispersed by the light scattering material 20 into a light wave directed toward the side wall of the quartz main body 10 and is emitted from the side wall of the quartz main body 10, and then when the light wave emitted from the side wall of the quartz main body 10 is received again by the photoelectric device, the received light wave energy is reduced, so that the photoelectric device is convenient for photoelectric conversion, and damage of the photoelectric device due to direct reception of the light beam with high energy density is avoided, so that collection of the light beam with high energy density is realized at the receiving end of long-distance wireless energy transmission.
In addition, in the light-passing structure provided in the embodiment of the present application, the light wave with dispersed energy emitted from the side wall of the quartz body 10 can be used for functions such as illumination and radiation by using the reflection or scattering effect of the light-scattering material 20 distributed in the quartz body 10 on the light beam incident into the quartz body 10.
It should be noted that, in the embodiment of the present application, since the light diffusing material 20 is distributed in the quartz body 10, the light diffusing material 20 may form a plurality of reflection or scattering centers in the quartz body 10 as shown in fig. 1.
When the light diffusing material 20 forms a plurality of reflection centers in the quartz body 10, it can be understood that the light beam incident into the quartz body 10 is reflected by one reflection center, then is generally incident into another reflection center or centers, and is reflected by another reflection center or centers, and then is emitted from the side wall of the quartz body 10, so that the light beam incident into the quartz body 10 is dispersed in all directions to be emitted, as shown by a plurality of arrows around the side wall of the quartz body 10 in fig. 1, so that the light wave energy emitted from the side wall of the quartz body 10 is relatively uniform.
Similarly, when the scattering material 20 forms a plurality of scattering centers in the quartz body 10, the light beam incident into the quartz body 10 is scattered by one scattering center, and then is not only scattered in a plurality of directions, but also is again incident into another scattering center or scattering centers, and is scattered again by another scattering center or scattering centers, and then is emitted from the side wall of the quartz body 10 in all directions, as shown by a plurality of arrows around the side wall of the quartz body 10 in fig. 1, so that the energy of the light wave emitted from the side wall of the quartz body 10 is more uniform.
Alternatively, in one embodiment of the present application, the particle size of the light diffusing material 20 is 1/4 or more of the wavelength of the light beam and 4 or less of the wavelength of the light beam, so that the light beam incident into the quartz body 10 is diffused by the light diffusing material 20 toward the sidewall of the quartz body 10.
In this embodiment, since the particle size of the light-diffusing material 20 is 1/4 or more of the wavelength of the light beam and 4 or less of the wavelength of the light beam, that is, the particle size of the light-diffusing material 20 is small, the light beam incident into the quartz body 10 can be scattered by the light-diffusing material 20 toward the side wall of the quartz body 10, and emitted from the side wall of the quartz body 10 in all directions, so that the light wave energy emitted from the side wall of the quartz body 10 is more uniform.
Alternatively, in one embodiment of the present application, the light diffusing material 20 is a quantum dot material or a micro-nano crystalline material. Since the particle size of the quantum dot material is generally 1nm-10nm, and the micro-nano crystal material is a micro-scale and nano-scale crystal material, when the light scattering material 20 is a quantum dot material or a micro-nano crystal material, the particle size of the light scattering material 20 is smaller, so that the light beam entering the quartz main body 10 is scattered by the light scattering material 20 to the side wall of the quartz main body 10, and is emitted from the side wall of the quartz main body 10 in all directions, so that the light wave energy emitted from the side wall of the quartz main body 10 is more uniform.
In addition, because the melting point of the quantum dot material or the micro-nano crystal material is generally above 2500 ℃ under the nano effect scale, when the light scattering material 20 is the quantum dot material or the micro-nano crystal material, the light scattering material 20 has higher melting point, can resist high temperature and has extremely strong damage resistance.
Alternatively, in one embodiment of the present application, the light diffusing material 20 is a diamond quantum dot material. Firstly, the particle size of the diamond quantum dot material is small enough to enable light beams entering the quartz main body 10 to be scattered to the side wall of the quartz main body 10 by the light scattering material 20, and the light beams are emitted from the side wall of the quartz main body 10 in all directions, so that the light wave energy emitted from the side wall of the quartz main body 10 is more uniform; secondly, the melting point of the diamond quantum dot material is generally 3000-4000 ℃, the melting point is very high, the diamond quantum dot material can resist high temperature, and the diamond quantum dot material has very strong damage resistance; in addition, the diamond quantum dot material has ultrahigh heat conductivity and excellent stability, and is favorable for heat dissipation of the light flux structure.
Optionally, in an embodiment of the present application, the particle size of the light diffusing material 20 ranges from 0.1nm to 20 μm, including the end point value, that is, the particle size of the light diffusing material 20 is smaller, so that the light beam incident into the quartz body 10 is scattered by the light diffusing material 20 toward the side wall of the quartz body 10, and is emitted from the side wall of the quartz body 10 in all directions, so that the light wave energy emitted from the side wall of the quartz body 10 is more uniform.
Alternatively, in one embodiment of the present application, as shown in fig. 1, the concentration of the light diffusing material 20 distributed in the quartz body 10 is gradually larger along the transmission direction (first direction X) of the light beam.
This is because, along the transmission direction (first direction X) of the light beam, the front section of the quartz body 10 receives a light beam having a greater energy density, and therefore requires fewer scattering centers to enable the light wave energy emitted from the side wall of the quartz body 10 to reach a preset value, whereas, since the light beam has been scattered in a portion of the front section of the quartz body 10, the rear section of the quartz body 10 receives a light beam having a reduced energy density, and thus requires more scattering centers to enable the light wave energy emitted from the side wall of the quartz body 10 to reach a preset value, and further enables the light wave energy emitted from the side wall of the quartz body 10 as a whole to be more uniform, resulting in a more uniform light wave distribution.
Alternatively, in one embodiment of the present application, the concentration of the light diffusing material 20 distributed in the quartz body 10 is continuously gradually increased along the transmission direction (first direction X) of the light beam on the basis of the above-described embodiment.
Alternatively, in another embodiment of the present application, the quartz body 10 is divided into N segments along the transmission direction of the light beam (first direction X), and in the quartz body, the concentration of the light-diffusing material 20 distributed in the i+1th segment is greater than that of the light-diffusing material 20 distributed in the i-th segment, i.e., the concentration of the light-diffusing material 20 distributed in the quartz body 10 gradually increases in segments along the transmission direction of the light beam (first direction X).
For ease of application, in an embodiment of the present application, the quartz body 10 is a polygonal cylinder or a cylindrical body, and the first end 11 and the second end 12 of the quartz body 10 correspond to two bottom surfaces of the polygonal cylinder or the cylindrical body, as shown in fig. 1, alternatively.
The embodiment of the application also provides a wireless energy transmission system, fig. 2 shows a schematic diagram of the wireless energy transmission system provided in the embodiment of the application, as shown in fig. 2, where the wireless energy transmission system includes:
a light source 100, the light source 100 being configured to emit a light beam transmitted along a first direction X;
a light-passing structure 200 located on a transmission path of the light beam, as shown in fig. 1 and 2, the light-passing structure 200 including a quartz body 10 and a light-scattering material 20 distributed in the quartz body 10;
wherein the quartz body 10 extends along a first direction X, the quartz body 10 has a first end 11 and a second end 12 disposed opposite along the first direction X, the first end 11 of the quartz body 10 receiving a light beam emitted by the light source 100 and transmitted along the first direction X;
the refractive index of the light-diffusing material 20 is different from that of the quartz body 10, so that the light beam incident into the quartz body 10 is reflected or scattered by the light-diffusing material 20 toward the side wall of the quartz body 10 and is emitted from the side wall of the quartz body 10.
In this embodiment, the quartz body 10 is located on the transmission path of the light beam, and the light beam transmitted along the first direction X by the light source 100 is specifically shown by the solid line with arrow on the left side of the first end 11 of the quartz body 10 in fig. 1-2, and is received by the first end 11 of the quartz body 10, where the light beam may be a light beam with high energy density for long-distance wireless energy transmission.
Optionally, the light beam may be a laser beam, where the laser beam may be a laser beam of 500nm, 808nm or 1060nm, and the laser beam is emitted from a single light source 100 (e.g., a laser element source) with advantages of uniformity, concealment (non-visible light), low divergence, and low thermal effect; alternatively, the light beam may be a concentrated solar beam, and in this case, the light source 100 may be a lens with a light concentrating effect, or the like.
In view of the requirement that the light flux of high energy density is incident on the light-passing structure, the light-passing structure body is resistant to high temperature, high energy and damage, and therefore, in the embodiment of the present application, the quartz body 10 is resistant to high temperature, high energy and damage is used as the light-passing structure body.
In practical applications, the light-passing structure 200 may be prepared by a hot-melt method. Specifically, the light diffusing material 20 is doped into the quartz frit while the quartz is hot-melted, and then shaped to form the light passing structure 200. However, the present application is not limited thereto, and the light-passing structure 200 may be formed by doping the light-diffusing material 20 into the quartz body 10 by an electric melting method, an air melting method, a chemical vapor deposition synthesis method, in-situ doping, co-growth, or the like.
The wireless energy transmission system provided by the embodiment of the utility model can be applied to long-distance wireless energy transmission, because the light scattering material 20 is distributed in the quartz main body 10 of the light-passing structure 200, and the refractive index of the light scattering material 20 is different from that of the quartz main body 10, the light scattering material 20 in the quartz main body 10 can be used as a reflection or scattering center, so that light beams entering the quartz main body 10 are reflected or scattered by the light scattering material 20 to the side wall of the quartz main body, namely, the light beams entering the quartz main body 10 are effectively scattered by the light scattering material 20 into light waves which are emitted to the side wall of the quartz main body 10 and are emitted from the side wall of the quartz main body 10, when the photoelectric device receives the light waves emitted from the side wall of the quartz main body 10 again, the received light wave energy is reduced, the photoelectric device is convenient to perform photoelectric conversion, and the photoelectric device is prevented from being damaged due to directly receiving the light beams with high energy density, so that the collection of the light beams with high energy density is realized at the receiving end of long-distance wireless energy transmission.
In addition, the wireless energy transmission system provided in the embodiment of the present application may further utilize the reflection or scattering effect of the light scattering material 20 distributed in the quartz body 10 on the light beam incident into the quartz body 10, so that the light wave with energy emitted from the side wall of the quartz body 10 is used for functions of illumination, radiation, and the like.
Fig. 3 shows a schematic diagram of another wireless energy transmission system according to an embodiment of the present application, as shown in fig. 3, where the wireless energy transmission system further includes:
the first photovoltaic device 300 is disposed around the sidewall of the quartz body 10, and is used to absorb light emitted from the sidewall of the quartz body 10 and to convert energy of the light emitted from the sidewall of the quartz body 10 into electric energy.
In this embodiment, the first photoelectric device 300 is disposed around the side wall of the quartz body 10, so as to absorb the light emitted from the side wall of the quartz body 10, and perform photovoltaic power generation, so as to convert the energy of the light emitted from the side wall of the quartz body 10 into electric energy, and due to the reflection or scattering effect of the light scattering material 20 distributed in the quartz body 10 on the light beam incident into the quartz body 10, the light wave energy received by the first photoelectric device 300 is reduced, so that the first photoelectric device 300 is convenient for performing photoelectric conversion, and the first photoelectric device 300 is prevented from being damaged due to directly receiving the light beam with high energy density, so as to collect the light beam with high energy density at the receiving end of long-distance wireless energy transmission, thereby truly realizing long-distance wireless energy transmission.
In this embodiment, the first photovoltaic device 300 may be a flexible photovoltaic device so as to be disposed around the sidewall of the quartz body 10.
Considering that the second end 12 of the quartz body 10 of the light-passing structure 200 may also have a light wave output, therefore, optionally, in one embodiment of the present application, as shown in fig. 4, fig. 4 shows a schematic diagram of a wireless energy transmission system provided by the present embodiment, and it can be seen that a part of a light beam is emitted from the second end 12 of the quartz body 10 through the quartz body 10, and the wireless energy transmission system further includes:
and a second photovoltaic device 400, the second photovoltaic device 400 being located at the second end 12 of the quartz body 10 for absorbing light emitted from the second end 12 of the quartz body 10 and converting energy of the light emitted from the second end 12 of the quartz body 10 into electric energy.
In this embodiment, not only the first photovoltaic device 300 is disposed around the side wall of the quartz body 10 to absorb the light emitted from the side wall of the quartz body 10 and perform photovoltaic power generation to convert the energy of the light emitted from the side wall of the quartz body 10 into electric energy, but also the second photovoltaic device 400 is disposed at the second end of the quartz body 10 to absorb the light emitted from the second end 12 of the quartz body 10 and perform photovoltaic power generation to convert the energy of the light emitted from the second end 12 of the quartz body 10 into electric energy, that is, to achieve full utilization of the beam energy and improve the energy utilization rate of the wireless energy transmission system.
In the above embodiments, since the light diffusing material 20 is distributed in the quartz body 10, the light diffusing material 20 may form a plurality of reflection or scattering centers in the quartz body 10 as shown in fig. 1 to 4.
When the light diffusing material 20 forms a plurality of reflection centers in the quartz body 10, it can be understood that the light beam incident into the quartz body 10 is reflected by one reflection center, then is generally incident into another reflection center or centers, and is reflected by another reflection center or centers, and then is emitted from the side wall of the quartz body 10, so that the light beam incident into the quartz body 10 is dispersed in all directions to be emitted, as shown by a plurality of arrows around the side wall of the quartz body 10 in fig. 1-4, so that the light wave energy emitted from the side wall of the quartz body 10 is relatively uniform.
Similarly, when the scattering material 20 forms a plurality of scattering centers in the quartz body 10, the light beam incident into the quartz body 10 is scattered by one scattering center, and then is not only scattered in a plurality of directions, but also is again incident into another scattering center or scattering centers, and is scattered again by another scattering center or scattering centers, and then is emitted from the side wall of the quartz body 10 in all directions, as shown by a plurality of arrows around the side wall of the quartz body 10 in fig. 1, so that the energy of the light wave emitted from the side wall of the quartz body 10 is more uniform.
Alternatively, in one embodiment of the present application, the particle size of the light diffusing material 20 is 1/4 or more of the wavelength of the light beam and 4 or less of the wavelength of the light beam, so that the light beam incident into the quartz body 10 is diffused by the light diffusing material 20 toward the sidewall of the quartz body 10.
In this embodiment, since the particle size of the light-diffusing material 20 is 1/4 or more of the wavelength of the light beam and 4 or less of the wavelength of the light beam, that is, the particle size of the light-diffusing material 20 is small, the light beam incident into the quartz body 10 can be scattered by the light-diffusing material 20 toward the side wall of the quartz body 10, and emitted from the side wall of the quartz body 10 in all directions, so that the light wave energy emitted from the side wall of the quartz body 10 is more uniform.
Alternatively, in one embodiment of the present application, the light diffusing material 20 is a quantum dot material or a micro-nano crystalline material. Since the particle size of the quantum dot material is generally 1nm-10nm, and the micro-nano crystal material is a micro-scale and nano-scale crystal material, when the light scattering material 20 is a quantum dot material or a micro-nano crystal material, the particle size of the light scattering material 20 is smaller, so that the light beam entering the quartz main body 10 is scattered by the light scattering material 20 to the side wall of the quartz main body 10, and is emitted from the side wall of the quartz main body 10 in all directions, so that the light wave energy emitted from the side wall of the quartz main body 10 is more uniform.
In addition, because the melting point of the quantum dot material or the micro-nano crystal material is generally above 2500 ℃ under the nano effect scale, when the light scattering material 20 is the quantum dot material or the micro-nano crystal material, the light scattering material 20 has higher melting point, can resist high temperature and has extremely strong damage resistance.
Alternatively, in one embodiment of the present application, the light diffusing material 20 is a diamond quantum dot material. Firstly, the particle size of the diamond quantum dot material is small enough to enable light beams entering the quartz main body 10 to be scattered to the side wall of the quartz main body 10 by the light scattering material 20, and the light beams are emitted from the side wall of the quartz main body 10 in all directions, so that the light wave energy emitted from the side wall of the quartz main body 10 is more uniform; secondly, the melting point of the diamond quantum dot material is generally 3000-4000 ℃, the melting point is very high, the diamond quantum dot material can resist high temperature, and the diamond quantum dot material has very strong damage resistance; in addition, the diamond quantum dot material has ultrahigh heat conductivity and excellent stability, and is favorable for heat dissipation of the light flux structure.
Optionally, in an embodiment of the present application, the particle size of the light diffusing material 20 ranges from 0.1nm to 20 μm, including the end point value, that is, the particle size of the light diffusing material 20 is smaller, so that the light beam incident into the quartz body 10 is scattered by the light diffusing material 20 toward the side wall of the quartz body 10, and is emitted from the side wall of the quartz body 10 in all directions, so that the light wave energy emitted from the side wall of the quartz body 10 is more uniform.
Alternatively, in one embodiment of the present application, as shown in fig. 1 to 4, the concentration of the light diffusing material 20 distributed in the quartz body 10 is gradually increased along the transmission direction (first direction X) of the light beam.
This is because, along the transmission direction (first direction X) of the light beam, the front section of the quartz body 10 receives a light beam having a greater energy density, and therefore requires fewer scattering centers to enable the light wave energy emitted from the side wall of the quartz body 10 to reach a preset value, whereas, since the light beam has been scattered in a portion of the front section of the quartz body 10, the rear section of the quartz body 10 receives a light beam having a reduced energy density, and thus requires more scattering centers to enable the light wave energy emitted from the side wall of the quartz body 10 to reach a preset value, and further enables the light wave energy emitted from the side wall of the quartz body 10 as a whole to be more uniform, resulting in a more uniform light wave distribution.
Alternatively, in one embodiment of the present application, the concentration of the light diffusing material 20 distributed in the quartz body 10 is continuously gradually increased along the transmission direction (first direction X) of the light beam on the basis of the above-described embodiment.
Alternatively, in another embodiment of the present application, the quartz body 10 is divided into N segments along the transmission direction of the light beam (first direction X), and in the quartz body, the concentration of the light-diffusing material 20 distributed in the i+1th segment is greater than that of the light-diffusing material 20 distributed in the i-th segment, i.e., the concentration of the light-diffusing material 20 distributed in the quartz body 10 gradually increases in segments along the transmission direction of the light beam (first direction X).
For ease of application, in an embodiment of the present application, as shown in fig. 1-4, the quartz body 10 is a polygonal cylinder or a cylindrical body, and the first end 11 and the second end 12 of the quartz body 10 correspond to two bottom surfaces of the polygonal cylinder or the cylindrical body, as an alternative to any of the above embodiments.
In summary, according to the light passing structure and the wireless energy transmission system provided by the embodiments of the present application, by distributing the light scattering material in the quartz main body, and the refractive index of the light scattering material is different from that of the quartz main body, the light beam incident into the quartz main body is reflected or scattered by the light scattering material toward the side wall of the quartz main body, that is, the light beam incident into the quartz main body is effectively dispersed into the light wave directed toward the side wall of the quartz main body by the light scattering material as the reflection or scattering center, and is emitted from the side wall of the quartz main body, so that when the photoelectric device receives the light wave emitted from the side wall of the quartz main body again, the received light wave energy is reduced, so that the photoelectric device is convenient for photoelectric conversion, and damage of the photoelectric device due to direct receiving of the light beam with high energy density is avoided, so that the collection of the light beam with high energy density is realized at the receiving end of long-distance wireless energy transmission. In addition, the light emitted from the side wall of the quartz main body can also be used for functions such as illumination, radiation and the like.
In the description, each part is described in a parallel and progressive mode, and each part is mainly described as a difference with other parts, and all parts are identical and similar to each other.
