Description

Photoelectric device

This disclosure relates to a photovoltaic device, and more particularly to a photovoltaic device in which laser light is continuously reflected to form a laser light network.

In daily life, whether in indoor or outdoor spaces, people are often disturbed by mosquitoes, which affects the quality of study, work or sleep, and even damages their health due to mosquito bites. Generally speaking, people usually use traditional electric mosquito slaps to catch mosquitoes. Traditional electric mosquito swats have a metal net with a current. When the mosquitoes contact the metal net to cause a short circuit, the mosquitoes are killed by the current. However, the traditional electric mosquito slap has a poor heat dissipation effect on the metal mesh under long-term use, and it is also easy to leave foreign matter on the metal mesh, and if the metal mesh is squeezed, it is easy to deform and cause a short circuit.

An embodiment of the present disclosure discloses a photovoltaic device including a frame-shaped body, a reflection unit, and a first laser emitter. The reflection unit is disposed on the inner surface of the frame body. The first laser emitter corresponds to the reflection unit disposed on the inner surface of the frame body. The first laser emitter emits laser light, and the laser light is continuously reflected by the reflection unit. The first laser light net is formed.

Please refer to FIG. 1 and FIG. 2, which respectively illustrate a schematic diagram of a photovoltaic device 100 according to an embodiment of the present disclosure document and A block diagram of a photovoltaic device 100 according to an embodiment. The optoelectronic device 100 includes a frame-shaped body 190, a reflection unit 192, and a laser emitter 160.

As shown in FIG. 1, the reflection unit 192 is provided on the inner surface of the frame-shaped body 190. The laser emitter 160 is disposed on the inner surface of the frame body 190 corresponding to the reflection unit 192. The laser emitter 160 projects laser light on the reflection unit 192 along an initial projection direction. The laser light is continuously reflected through the reflection unit 192 to form laser light. network. As shown in FIG. 2, the optoelectronic device 100 further includes a switch button 120, a control unit 140, and a light sensor 180. The laser transmitter 160 and the switch button 120 are electrically connected to the control unit 140. The switch button 120 is used for a user to press. The light sensor 180 is disposed on the inner surface of the frame body 190 to sense the energy level of the laser light. The control unit 140 is used to drive and turn off the projection of the laser transmitter 160. Laser light. Specific methods and various embodiments of how the laser light uses the frame-shaped body 190 and the reflection unit 192 to form an optical network will be described in detail in the following paragraphs.

Please refer to FIG. 3A together, which illustrates a method flowchart of a method for operating an optoelectronic device according to an embodiment of the present disclosure. First, in step S204, the laser transmitter 160 is driven. Laser light is projected on the area surrounded by the frame-shaped body 190, so that the laser light is reflected in the area surrounded by the frame-shaped body 190 to form a closed reflection path. In one embodiment, the frame-shaped body 190 is made of plastic, metal, wood, or other materials commonly used in daily life, but the scope covered by this disclosure is not limited to this embodiment, but in one embodiment The shape of the area surrounded by the frame-shaped body 190 may be circular, oval, square, rectangular, triangular, or polygonal. The scope covered is not limited to this embodiment. In some embodiments, the frame-shaped body 190 may be an open frame-shaped body with an opening, such as being surrounded by a semi-arc, L-shaped, or V-shaped open form. Please refer to FIG. 4 together, which illustrates a schematic diagram of a frame-shaped body 190 according to an embodiment of the disclosure document. Compared to FIG. 1, the frame-shaped body 190 in FIG. 4 has an opening. The laser emitter 160 emits laser light toward the reflection unit 192. The laser light is in a region surrounded by the frame-shaped body 190 (that is, a half with an opening above). (Curved area) forms a closed reflection path.

When the laser light is emitted, the laser light advances toward the reflection unit 192 with the laser emitter 160 as a starting point. After the laser light hits the reflection unit 192, the laser light is reflected by the reflection unit 192, and proceeds to the reflection unit 192 in the other direction, and the laser light is continuously reflected to form a laser light network. The above-mentioned continuous reflection means that the laser light is repeatedly reflected in the space formed by the reflection unit 192. For example, when the laser light hits the left side of the reflection unit 192, it is projected to the right side of the reflection unit 192 according to its reflection angle. When the laser light hits the right side of the reflection unit 192, it is reflected again according to its reflection angle. Another position on the left side of the unit 192 continues to project. The reflecting unit 192 is correspondingly disposed inside the frame-shaped body 190. After continuous multiple projections, a laser light net can be formed in the frame-shaped body 190. In this embodiment, the reflection unit 192 is a mirror surface, a metal capable of reflecting laser light, or other materials or coatings having a reflective effect, but the scope of the disclosure is not limited thereto. In some embodiments, the reflection unit 192 covers the entire inner surface of the frame-shaped body 190. In some embodiments, the reflection unit 192 covers only a part of the inner surface of the frame-shaped body 190, such as a circular frame. In the shape body, the reflection unit 192 only covers half, one third, or one tenth of the inner surface of the entire circular frame-shaped body 190. The reflection unit 192 may be provided according to the shape of the final laser light net.

In one embodiment, the reflection unit 192 is integrally formed and completely covers the entire inner surface of the frame-shaped body 190. In an embodiment, the optoelectronic device 100 includes a plurality of reflection units 192, each of which is a partial reflection section and correspondingly disposed on the inner surface of the frame-shaped body 190, so that the laser light can be continuously reflected to form a laser light network, Each reflection unit 192 covers only a part of the inner surface of the frame-shaped body 190.

In some embodiments, the shape of the reflection unit 192 matches the shape of the frame-shaped body 190. In some embodiments, the shape of the reflection unit 192 is different from the shape of the frame-shaped body 190. For example, please refer to FIG. 5 together, which illustrates a schematic view of a frame body 190 and a reflection unit 192 according to an embodiment of the present disclosure. Compared with the embodiment in FIG. 1, the frame body 190 in FIG. 5 is composed of a pair of semi-arc structures with openings. The shapes of the two reflection units 192 provided on the inner surface of the semi-arc structure are The semi-curved structure is different. As shown in the figure, the reflection unit 192 is a long strip.

Please refer to FIG. 7A to FIG. 7E together, which are schematic diagrams of a laser light net according to an embodiment of the present disclosure. As mentioned above, in different embodiments, the frame-shaped body 190 is presented in different surrounding forms. For convenience of illustration, the frame-shaped body 190 in FIGS. 7A to 7E is presented in a rectangular form.

As shown in FIG. 7A, the laser light emitted by the laser transmitter 160 advances in the direction D1. The direction of laser light D1 will be reflected by the laser light. The position P1 forms an incident angle A1 with respect to the normal line D2 of the reflection unit 192. When the laser light is reflected by a reflection unit (not shown in FIG. 7A) on the inner surface of the frame-shaped body 190, the laser light continues to be projected in a direction D3 toward another part of the frame-shaped body 190 (that is, where the other reflection unit is located). The reflection direction D3 of the laser light and the normal line D2 of the reflection unit form an exit angle A2, and the incident angle A1 is equal to the exit angle A2. After the laser light is reflected by the position P1, it continues to be projected to the inner surface of the other side of the frame body 190, and so on. A reflection unit is set in the reflection path of the laser light, and the laser light can be continuously in the frame body 190. reflection.

After the laser light is reflected in the manner described above for multiple times, a laser light net 161 is formed in the area surrounded by the frame-shaped body 190 in step S206, as shown in FIG. 7A. The density of the laser light network is determined according to the incident angle formed by the initial projection direction of the laser light and the normal line D2 of the reflection unit 192. That is, when the incident angle is smaller, the formed laser light net is denser. On the contrary, when the incident angle is larger, the formed laser light net is more dispersed.

For example, in an embodiment, when the laser emitter 160 projects laser light in an initial projection direction, the projection direction of the laser light and the normal of the reflection unit 192 form an incident angle A3, and the laser light net 162 finally formed is Figure 7B. On the other hand, when the laser emitter 160 projects laser light in another initial projection direction, the projection direction of the laser light and the normal of the reflection unit 192 form an incident angle A4, and the formed laser light network 163, as shown in FIG. 7C As shown. Since the incident angle A3 is smaller than the incident angle A4, the density of the laser light network 162 formed in FIG. 7B is relatively greater than that formed in FIG. 7C. The density of the laser light network 163.

In another embodiment, two different laser emitters are respectively provided on the inner surface of the frame-shaped body 190. When the two laser emitters simultaneously project laser light at an incident angle, a denser structure can be formed. High laser light net.

As shown in FIG. 7D, when the laser emitter 160a is set at the lower left corner of the frame body 190, the first laser light projected by the laser emitter 160a may form a first laser light net 164. At this time, as shown in FIG. 7E, if the laser emitter 160b is added to the upper right corner of the frame body 190, the laser emitter 160b projects the second laser light. When the laser emitter 160a and the laser emitter 160b simultaneously project laser light, the first laser light and the second laser light can form a second laser light network 165 having a density that is twice that of the first laser light network 164, such as Figure 7E.

However, in different embodiments, the number and position of the laser emitters provided on the inner surface of the frame body may be different. In other words, in another embodiment, two or more laser emitters are provided on the inner surface of the frame body. And the positions of the laser emitters will be close to each other, and at the same time, the laser light is projected to form another high-density laser light network. However, it should be understood that the scope covered by this disclosure is not limited to the above embodiments.

The closed reflection paths formed by the laser light continuously reflected in the above embodiments fall on the same plane, but in other embodiments, the closed reflection paths formed by the laser light do not fall on the same plane. For example, please refer to FIG. 6 together, which illustrates a schematic diagram of a laser light path according to an embodiment of the present disclosure. Compared with the above embodiment, the laser light station of FIG. 6 The closed path formed does not fall on a plane. In this embodiment, the frame-shaped bodies 190 on the left and right sides are disposed in a non-parallel manner. As shown in FIG. 6, the frame-shaped body 190 is a pair of semi-arc structures, the semi-arc structure on the left is a U-shaped structure extending in the horizontal direction, and the semi-arc structure on the right includes a U-shaped structure extending in the vertical direction. . The laser light is continuously reflected by the reflection unit 192 of the frame-shaped body 190, and the four laser lights (that is, the four arrows in the figure) reflected by the reflection unit 192 in FIG. 6 form a closed path laser light network. Did not fall on the same plane. In an embodiment, since the frame body 190 in FIG. 5 and FIG. 6 is composed of a pair of half-arc structures, the two half-arc structures can be connected by a Y-shaped handle, and the switch button 120 can be Set on a Y-shaped handle.

That is to say, the laser light nets formed in the present disclosure may fall on the same plane or be distributed on different planes.

In an embodiment of the present disclosure, the energy level (for example, 0.1 Joules per second) of the laser light (for example, a blue laser or a green laser) projected by the laser transmitter is greater than a threshold value that a general mosquito can withstand. (For example, 0.04 joules per second), when the mosquito enters the frame body and contacts the laser light net, the wings of the mosquito will be destroyed by the laser light and lose their activity, thereby achieving the purpose of catching mosquitoes. The blue laser or green laser, the energy level of the laser light (0.1 Joules per second), and the critical value that the mosquito can withstand (0.04 Joules per second) are only provided as examples.

Generally speaking, the intensity of the laser light projected by the laser transmitter will not cause harm to the human body. For the average person, the intensity of such laser light is roughly similar to the laser index used in the projection presentation or the visual for viewing. special Effect laser. It does not cause immediate harm in the case of short-term exposure.

In another embodiment, in addition to activating the laser transmitter to project laser light and forming a laser light network in the frame body, the operation of the optoelectronic device further includes the steps of controlling the switch button and detecting the laser light.

Please refer to FIG. 3B together, which illustrates a method flowchart of a method for operating a photovoltaic device according to an embodiment of the present disclosure. In step S202, the switch button 120 in the photovoltaic device 100 is electrically connected to the control unit 140. When the user does not press the switch button 120, the control unit 140 will not drive the laser emitter 160 to project laser light, that is, the photoelectric device 100 will not operate at this time, and directly proceeds to step S212 to turn off the laser emitter 160. , Waiting for the next time the user presses the switch button 120.

Conversely, when the user presses the switch button 120, in step S204, the control unit 140 receives a driving instruction to drive the laser transmitter 160 to project laser light. At this time, the laser light is reflected on the frame body through the reflection unit 192 A laser light net is formed in 190, and the detailed method of forming the laser light net is the same as that described in the above paragraph, and is not repeated here.

As mentioned above, the laser light projected by the laser transmitter 160 has its corresponding energy level. In one embodiment, its energy level is greater than the critical value that daily mosquitoes can withstand. Therefore, when the user presses the switch button to drive the formation of the laser light net, and wave the photoelectric device where the mosquito is located. When the mosquito enters the swept area and contacts the laser light net, its wings will be destroyed, causing the mosquito to lose its ability to move, and further achieve The purpose of exterminating mosquitoes.

However, although the laser light network projected by the laser transmitter can be broken The wings of bad mosquitoes make them inactive and may affect the human body. For example, when the human body accidentally touches the laser light net while reaching into the frame-shaped body, it may still have a negative impact on the human body. For example, laser light may still be dangerous if it hits the eyes, the sensitive skin of children, or the human body for a long time. Therefore, the built-in light sensor of the optoelectronic device disclosed in this disclosure document is used to sense the energy level of the laser light, so as to avoid causing human harm without affecting the normal function.

In step S208, when the laser light is projected and a laser light net is formed in the frame body 190, the light sensor 180 in the photoelectric device 100 starts to detect the energy level of the laser light. When the user presses the switch button, within a period of time (for example, 2 milliseconds), the light sensor 180 determines in step S210 that the detected energy level of the laser light is less than the threshold energy, indicating that there is a foreign object (for example, using Fingers, other parts of the body, or clothing) enter the projection path of the laser light network and block most of the laser light. The light sensor 180 sends a warning signal to the control unit 140. When the control unit 140 receives After this warning signal, in step S212, the control unit 140 forcibly turns off the laser transmitter 160 and stops projecting laser light, thereby avoiding causing harm to the user.

In another embodiment, when the light sensor 180 determines in step S210 that the energy level of the detected laser light is greater than the threshold energy, the light sensor 180 does not interfere with the operation of the laser emitter 160 at this time, so The laser transmitter 160 is continuously driven to project laser light. Regarding the time zone, the present disclosure is not limited to the above embodiment. In other embodiments, the time zone is 10 milliseconds, 50 milliseconds, or 1 second.

Please refer to FIG. 8A together, which illustrates a waveform of an energy level of laser light projected by the laser transmitter 160 according to an embodiment of the present disclosure. In one embodiment, the laser emitter 160 projects laser light into the frame body 190 to form a laser light network. The laser light network has the energy level E1 of the laser light, and the waveform of the energy of the laser light is as shown in FIG. 8A. It is shown that in this embodiment, the energy waveform of the laser light has a periodic pulse width waveform, but this disclosure is not limited to this. In other embodiments, the energy of the laser light may also have a constant energy that is continuously maintained. Level, or other waveforms with equality.

Please refer to FIGS. 8B-8D together, which show the energy levels of the laser light detected by the light sensor 180 of the present embodiment in different embodiments. In an embodiment, as shown in FIG. 8A, when the laser light net is formed on the frame-shaped body 190, the mosquito that is positively small enters the laser light net in the frame-shaped body and comes into contact with it in the time section T1. Laser light net, part of the laser light will be blocked. At this time, the energy of the laser light detected by the light sensor 180 in the time section T1 is reduced from the energy level E1 to the energy level E2, as shown in FIG. 8B.

However, because the body occupied by the mosquito is very small, only a small part of the laser light can be blocked in the frame-shaped body, so that the degree of energy reduction is not obvious. Therefore, although the energy level of the laser light is reduced from the energy level E1 to the energy level Bit E2, the light sensor 180 determines that the energy level E2 is still greater than the threshold energy Eth preset by the light sensor 180. In this case, it means that the volume of the object that enters the frame body 190 and contacts the laser light is small ( For example, mosquitoes), the laser light blocked by this object is relatively small. Therefore, in this case, the light sensor 180 does not notify the control unit 140 to turn off the laser transmitter 160.

As shown in FIG. 8C, when the laser light net is formed on the frame-shaped body 190, at this time, an entity having a certain volume (such as a human body part such as a finger, a palm, or a head) enters the frame-shaped body 190 and is in the time section T1. Internal contact with laser light will block some laser light as in the above embodiment. At this time, the energy level of the laser light detected by the light sensor 180 in the time section T1 is reduced from the energy level E1 to the energy level. E3, as shown in Figure 8C.

However, because the above-mentioned entities are larger in volume than mosquitoes, the laser light is blocked by more parts, so the energy level of the laser light decreases to a greater extent. At this time, the energy level of the laser light drops to the energy level E3, and the energy level E3 is smaller than the threshold energy Eth preset by the light sensor 180. In this case, the light sensor 180 will actively notify the control unit 140 to turn off The laser transmitter 160 stops projecting laser light. In this way, the entity (such as the user's fingers or other parts of the body) will not be irradiated by the laser light and then be harmed, so as to achieve the purpose of using the photoelectric device safely.

As shown in FIG. 8D, when the laser light net is formed on the frame-shaped body 190, if an entity (such as any part of the human body or any object with a certain volume) enters the frame-shaped body 190 in the time section T1 Laser light network, and completely shield the launch port of the laser transmitter 160 so that the laser light cannot be projected to form a laser light network. At this time, the light sensor 180 cannot sense any energy level of the laser light.

In this case, the energy level E4 of the laser light detected by the light sensor 180 in the time section T1 is 0, which is less than the threshold energy Eth preset by the light sensor 180, as shown in FIG. 8D. . Therefore, similarly, the light sensor 180 will actively notify the control unit 140 to turn off the laser emitter 160.

The energy levels E1 to E4 and the time period T1 mentioned above are only exemplary descriptions, and the scope covered by this disclosure is not limited to the above embodiments.

The optoelectronic device disclosed in this disclosure can project laser light on a reflection unit. The laser light is continuously reflected to form a laser light net in a frame-shaped body. The laser light net can be applied to eliminate mosquitoes. In some embodiments, the optoelectronic device further includes a switch button and a light sensor. When the user presses the button, a laser light network is formed, and the energy level of the laser light is detected by the light sensor. When a foreign object (such as a part of the user's body) enters the laser light net, the light sensor can forcibly stop the laser light projection to achieve the purpose of safety.
