Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical technology, and in particular to a head-mounted optical device. Background Technology
[0002] Phototherapy refers to the use of visible and invisible light from sunlight and artificial light sources to prevent and treat diseases and promote physical recovery. Among these methods, irradiating the skin with light of specific wavelengths is recognized as beneficial; for example, red light with a wavelength of 650nm has been shown to stimulate hair follicles, achieving the effects of hair growth or preventing hair loss.
[0003] Head-mounted optical devices, also known as optical hair-growth caps, are optical devices applied to the human head to address hair loss and thinning. They work by using specific wavelengths of light to stimulate hair follicles and promote hair growth. Current technology requires high-power output for this specific light to reach the hair follicles, but this high-power light is often too strong for the user's eyes. During or when not in use, unexpected events could lead to eye damage or other serious accidents, resulting in a poor user experience. Utility Model Content

Detailed Implementation
[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0034] Figure 1 This is a bottom-view structural diagram of a head-mounted optical device provided in an embodiment of this utility model. Figure 2 This is a cross-sectional structural diagram of a head-mounted optical device provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the communication connection of a head-mounted optical device provided in an embodiment of this utility model, as shown below. Figure 1 , Figure 2 and Figure 3 As shown, the head-mounted optical device includes: a housing 10, an inner wall 100 having a light-transmitting area, an outer side of the inner wall 100 forming a cavity 102 for the user to wear, and an opening 101 below the cavity 102 for the user's head to extend into the cavity 102 for wearing; a light source assembly disposed on the inner side of the inner wall 100 and having multiple light sources 11, each light source 11 capable of emitting light to the outside through the light-transmitting area; a first sensor 12 mounted on the housing 10, the first sensor 12 being used to detect whether the user is wearing the head-mounted optical device; and a second sensor 13 mounted on... On the housing 10, the second sensor 13 is used to detect the orientation of the opening 101 relative to the ground in three-dimensional space when the head-mounted optical device is referenced to the ground. This includes a first posture of the head-mounted optical device when the opening 101 is pointing towards the ground, and a second posture of the head-mounted optical device when the opening 101 is facing away from the ground. The control circuit 15 is configured to: turn on the light source assembly when the user is wearing the head-mounted optical device and the head-mounted optical device is in the first posture; and turn off the light source assembly when the user is not wearing the head-mounted optical device, and / or when the head-mounted optical device is in the second posture.
[0035] Specifically, the head-mounted optical device includes a housing 10, a light source assembly, a first sensor 12, a second sensor 13, and a control circuit 15. The first sensor 12 and the second sensor 13 acquire the wearing status and posture of the head-mounted optical device to determine whether the light source 11 of the head-mounted optical device meets the working conditions, thereby controlling the opening or closing of the light source assembly to avoid damage to the user's eyes caused by unexpected events due to improper use of the user, such as light output from the light source assembly entering the eyes.
[0036] The housing 10 has an inner wall 100 with a light-transmitting area. The inner wall 100 can be understood as the side of the housing 10 that is close to the user's beauty or treatment area (exemplarily, the user's scalp). The light source 11 is disposed on the inner side of the inner wall 100. The light source 11 can emit light to the outside through the corresponding light-transmitting area. That is, the light-transmitting area provided on the inner wall 100 can facilitate the emission of light corresponding to the light source 11, and can also prevent the light source 11 and other electronic components on the inner side of the inner wall 100 from directly contacting the user's beauty or treatment area, so as to ensure the user's safety and comfort during the phototherapy process.
[0037] Exemplarily, the light source assembly may include a plurality of light sources 11. Exemplarily, the light-emitting end of the light source 11 may face the inner surface wall 100. And, an accommodating cavity 102 for a user to wear is formed on the outer side of the inner surface wall 100, and an opening 101 is provided below the accommodating cavity 102 for the user's head to be inserted into the accommodating cavity 102 to achieve wearing. Exemplarily, the shape and size of the accommodating cavity 102 may be determined according to the user's head parameters, and the shape, size and position of the opening 101 may also be determined according to the user's head parameters.
[0038] Specifically, a first sensor 12 is mounted on the housing 10. The first sensor 12 can detect whether the user is wearing the head-mounted optical device. For example, the first sensor 12 can be located on the outer side of the inner wall 100. For example, when the user's head extends into the receiving cavity 102 through the opening 101, it can be understood that the user is wearing the head-mounted optical device; when the user's head does not extend into the receiving cavity 102 through the opening 101, it can be understood that the user is not wearing the head-mounted optical device. The first sensor 12 can be connected to the control circuit 15 via a communication bus, so the wearing status of the head-mounted optical device and the user detected by the first sensor 12 can be transmitted to the control circuit 15. Furthermore, a second sensor 13 is mounted on the housing 10. The second sensor 13 can detect the orientation of the opening 101 relative to the ground in three-dimensional space when the head-mounted optical device is referenced to the ground. For example, the second sensor 13 can be located on the inner side of the inner wall 100. For example, when the head-mounted optical device uses the ground as a reference frame, if the orientation of the opening 101 relative to the ground in three-dimensional space is detected as pointing towards the ground, it can be understood that the head-mounted optical device is in a first posture; if the orientation of the opening 101 relative to the ground in three-dimensional space is detected as facing away from the ground, it can be understood that the head-mounted optical device is in a second posture. The second sensor 13 can be connected to the control circuit 15 via a communication bus, so the orientation of the opening 101 relative to the ground in three-dimensional space and the posture of the head-mounted optical device detected by the second sensor 13 can be transmitted to the control circuit 15. In this way, the control circuit 15 can determine whether the light source 11 is turned on or off based on whether the user is wearing the head-mounted optical device and the posture of the head-mounted optical device.
[0039] In one specific embodiment, the control circuit 15 can determine that the light source 11 is turned on only when the first sensor 12 detects that the user is wearing the head-mounted optical device and the second sensor 13 detects that the head-mounted optical device is in a first posture. For example, the head-mounted optical device also includes an execution unit 16, which is connected to the control circuit 15 via a communication bus. The execution unit 16 is also electrically connected to the light source 11. Thus, after the control circuit 15 determines that the light source 11 is turned on, the execution unit 16 can correspondingly turn on the light source 11, allowing the light source 11 to emit light through the light-transmitting area to act on and stimulate the hair follicles on the user's head located within the accommodating cavity 102, thereby promoting hair growth.
[0040] In another specific embodiment, when the first sensor 12 detects that the user is not wearing the head-mounted optical device, and / or when the second sensor 13 detects that the head-mounted optical device is in a second posture, the control circuit 15 can determine that the light source 11 is turned off. In other words, when the first sensor 12 detects that the user is not wearing the head-mounted optical device, regardless of whether the posture of the head-mounted optical device detected by the second sensor 13 is the first posture or the second posture, the control circuit 15 can directly determine that the light source 11 is turned off; or, when the second sensor 13 detects that the head-mounted optical device is in the second posture, regardless of whether the user is wearing the head-mounted optical device detected by the first sensor 12 or not, the control circuit 15 can directly determine that the light source 11 is turned off.
[0041] More specifically, when the first sensor 12 detects that the user is not wearing the head-mounted optical device and the second sensor 13 detects that the head-mounted optical device is in a second posture, the control circuit 15 can determine that the light source 11 is turned off; when the first sensor 12 detects that the user is not wearing the head-mounted optical device and the second sensor 13 detects that the head-mounted optical device is in a first posture, the control circuit 15 can determine that the light source 11 is turned off. When the first sensor 12 detects that the user is wearing the head-mounted optical device and the second sensor 13 detects that the head-mounted optical device is in a second posture, the control circuit 15 can determine that the light source 11 is turned off.
[0042] For example, the head-mounted optical device also includes an execution unit 16, which can be connected to the control circuit 15 via a communication bus. The execution unit 16 can also be electrically connected to the light source 11. Thus, after the control circuit 15 determines that the light source 11 is turned off, the execution unit 16 can turn off the turned-on light source 11 accordingly, or the execution unit 16 can keep the unlit light source 11 in a turned-off state, thereby preventing the light emitted by the light source 11 of the head-mounted optical device from being perceived by the user's eyes, effectively avoiding eye damage caused by unexpected events.
[0043] In summary, the light source 11 can only be turned on when the user is wearing the device and the opening 101 of the head-mounted optical device is facing the ground. If only one condition is met or neither condition is met, the light source 11 will always be turned off, or the already turned-on light source 11 will be turned off. This not only simplifies the structural design but also improves the control precision of the light source 11 of the head-mounted optical device, ensuring a high level of eye safety for the user during use or when not in use. It effectively prevents eye damage caused by unexpected events resulting from improper use of the device, where the light output from the light source 11 enters the eye.
[0044] In one embodiment, the head-mounted optical device uses a first sensor 12 to detect whether the user is wearing the head-mounted optical device, and a second sensor 13 to detect the orientation of the opening 101 relative to the ground in three-dimensional space when the head-mounted optical device is referenced to the ground. The light source 11 can only be turned on when the user is wearing the device and the opening 101 of the head-mounted optical device is in a first orientation pointing towards the ground. If only one condition is met or neither condition is met, the light source 11 is always turned off, or the already turned-on light source 11 is turned off. In this way, the head-mounted optical device provides a high level of eye safety for the user during use or when not in use, effectively avoiding the occurrence of eye damage caused by unexpected events due to improper use of the user, such as light output from the light source 11 entering the eye. This improves the safety of the head-mounted optical device and enhances the user experience.
[0045] In another embodiment, when the opening 101 of the head-mounted optical device faces upward, the first sensor 12 can detect whether any foreign objects, such as food or towels, have entered. At the same time, the second sensor 13 detects the orientation of the opening 101 of the head-mounted optical device relative to the ground reference frame. Under this usage condition, special usage scenarios can be met. That is, when the user places the optical device arbitrarily with the opening 101 facing upward, even if an object enters the device and triggers the first sensor 12, the second sensor 13 will obtain attitude information and thus not trigger the light source 11 to turn on. In other words, the light source 11 will only have a preset action if the first sensor 12 and the second sensor 13 simultaneously meet the triggering conditions. This also ensures that in actual usage scenarios, if an unexpected usage condition is triggered, the light emitted by the light source 11 will still not enter the user's eyes, thereby greatly improving the safety of device use.
[0046] In some embodiments, reference Figure 1 As shown, the first sensor 12 includes an output terminal 120 and a receiving terminal 121, and the output terminal 120 and the receiving terminal 121 are respectively disposed on opposite sides inside the housing 10. Further, the first sensor 12 is an infrared sensor.
[0047] Specifically, the first sensor 12 used in the head-mounted optical device can be an infrared sensor, which has an output end 120 and a receiving end 121. The output end 120 and the receiving end 121 of the infrared sensor are respectively located on opposite sides inside the housing 10, that is, the output end 120 and the receiving end 121 of the infrared sensor are respectively located on opposite sides of the opening 101. For example, the output end 120 of the first sensor 12 can be located on the left side of the opening 101, and the receiving end 121 of the first sensor 12 can be located on the right side of the opening 101. Alternatively, the output end 120 of the first sensor 12 can be located on the front side of the opening 101, and the receiving end 121 of the first sensor 12 can be located on the rear side of the opening 101. This embodiment is only an example, and other relative positions are within the protection scope of this embodiment.
[0048] Furthermore, the electrical connection between the output terminal 120 and the receiver terminal 121 of the first sensor 12 is maintained when the user's head is not inserted into the accommodating cavity 102 through the opening 101, i.e., when the user is not wearing the head-mounted optical device. This connection remains unobstructed, meaning the first sensor 12 detects a connection signal between the output terminal 120 and the receiver terminal 121. Conversely, when the user's head is inserted into the accommodating cavity 102 through the opening 101, i.e., when the user is wearing the head-mounted optical device, the connection between the output terminal 120 and the receiver terminal 121 is blocked by the user's head, thus severing the electrical connection between the receiver terminal 121 and the output terminal 120. The receiver terminal 121 cannot receive the signal from the output terminal 120, meaning the first sensor 12 detects a disconnection signal between the output terminal 120 and the receiver terminal 121.
[0049] Furthermore, to improve the detection accuracy of the head-mounted optical device regarding whether a user is wearing it, the number of first sensors 12 can be increased; that is, multiple first sensors 12 can be provided. For example, multiple infrared sensors can be provided. For example, multiple infrared sensors can be evenly distributed within the housing 10, that is, multiple infrared sensors can be evenly distributed in the accommodating cavity 102. For example, the head-mounted optical device can be provided with two infrared sensors. The output end 120 of one infrared sensor can be located on the left side of the opening 101, and the receiving end 121 can be located on the right side of the opening 101. The output end 120 of the other infrared sensor can be located on the front side of the opening 101, and the receiving end 121 can be located on the rear side of the opening 101, thereby improving the measurement accuracy of the head-mounted optical device. This embodiment is merely an example; other relative positions and quantities are within the scope of protection of this embodiment.
[0050] Optionally, Figure 4 This is a bottom-view structural diagram of another head-mounted optical device provided in this embodiment of the present invention, as shown below. Figure 4 As shown, the first sensor 12 is a distance sensor.
[0051] Specifically, the first sensor 12 used in this head-mounted optical device can be a distance sensor. Distance sensors have advantages such as lower cost and more flexible installation location. For example, the distance sensor can be set at the bottom of the cavity 102. Furthermore, the distance sensor can detect the distance from the user's head to the bottom of the cavity 102. When the user's head is inserted into the cavity 102 through the opening 101, that is, when the user is wearing the head-mounted optical device, if the distance detected by the distance sensor is less than or equal to a preset value, it can be understood that the status information detected by the first sensor 12 at this time includes the on signal of the first sensor 12. In other words, when the distance detected by the distance sensor is less than or equal to the preset value, it can be understood that the user is wearing the head-mounted optical device at this time. When the user's head is not inserted into the receiving cavity 102 through the opening 101, that is, when the user is not wearing the head-mounted optical device, the distance detected by the distance sensor is greater than the preset value. This can also be understood as the status information detected by the first sensor 12 at this time including the non-connection signal of the first sensor 12. In other words, when the distance detected by the distance sensor is greater than the preset value, it can be understood that the user is not wearing the head-mounted optical device at this time.
[0052] Furthermore, to improve the detection accuracy of the head-mounted optical device regarding whether a user is wearing it, the number of first sensors 12 can be increased; that is, multiple first sensors 12 can be provided. For example, multiple distance sensors can be provided. For example, multiple distance sensors can be evenly distributed within the housing 10, that is, multiple distance sensors can be evenly distributed in the accommodating cavity 102. Each distance sensor detects the relative distance from its location to the user's head at its respective position. For example, if the distances detected at multiple positions are all less than or equal to a preset value, it can be understood that the user is wearing the head-mounted optical device, thereby improving the measurement accuracy of the head-mounted optical device and avoiding false triggering due to the failure of a single distance sensor.
[0053] Furthermore, it is understood that the first sensor 12 may also have other forms, as long as it can detect whether the user is wearing the head-mounted optical device, and is not limited to the two forms in the above embodiments.
[0054] In some embodiments, alternatively, continue to refer to Figure 2 The second sensor 13 is an attitude sensor.
[0055] Specifically, the second sensor 13 used in the head-mounted optical device can be an attitude sensor, such as an IMU (Inertial Measurement Unit). Exemplarily, the attitude sensor can be housed within the housing 10. The attitude sensor can detect the orientation of the opening 101 relative to the ground in three-dimensional space when the head-mounted optical device is using the ground as a reference frame. For example, when the opening 101 is pointing towards the ground in three-dimensional space, the attitude sensor detects that the head-mounted optical device is in a first attitude; when the opening 101 is facing away from the ground in three-dimensional space, the attitude sensor detects that the head-mounted optical device is in a second attitude.
[0056] Specifically, the opening 101 is located below the housing 10 to allow the user to wear the head-mounted optical device. The opening 101 defines an orientation 1010, and the second sensor 13 is mounted on the housing 10 to detect the angle between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground to determine the orientation of the head-mounted optical device relative to the ground, thereby determining the attitude of the head-mounted optical device in three-dimensional space.
[0057] In a more easily understood way, Figures 5a-5h This is a schematic diagram showing the angles between the orientation of eight openings and the vertical line to the ground, as provided in this embodiment of the utility model. Figures 6a-6d These are schematic diagrams illustrating the four opening orientations and user wearing postures provided in this embodiment of the utility model, as shown below. Figures 5a-5h ,as well as Figures 6a-6d As shown in the figure, this embodiment explains in detail the specific situations of the first and second postures corresponding to the head-mounted optical device.
[0058] In one specific embodiment, Figure 5a The angle α between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is 0°, indicating that the orientation 1010 of the opening 101 relative to the ground in three-dimensional space is pointing towards the ground and perpendicular to the ground. That is, the head-mounted optical device is in the first posture at this time. In this posture, if the first sensor 12 detects that the user is wearing the head-mounted optical device, the light source 11 can be turned on. Figure 5a The image shown can also be interpreted as the user's normal wearing state, and can be used as a reference. Figure 6a .
[0059] Figure 5b and Figure 5cThe angle α between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is an acute angle. Although it is not perpendicular to the ground, the orientation 1010 of the opening 101 relative to the ground in three-dimensional space still points towards the ground. That is, the head-mounted optical device is in the first posture at this time. In this posture, if the first sensor 12 detects that the user is wearing the head-mounted optical device, the light source 11 can be turned on. Figure 5b and Figure 5c The image shown can also be interpreted as the user's head being tilted upwards or downwards while wearing the device; please refer to the corresponding image. Figure 6b and Figure 6c As shown.
[0060] It should also be noted that the first attitude also includes the attitude of the head-mounted optical device when the opening 101 is oriented 1010 parallel to the ground. That is, Figure 5d and Figure 5e The angle α between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is a right angle (90°), which is parallel to the ground. At this time, the orientation 1010 of the opening 101 relative to the ground in three-dimensional space can be understood as parallel to the ground. The head-mounted optical device can still be in the first posture (which can be considered a supplement to the first posture). In this posture, if the first sensor 12 detects that the user is wearing the head-mounted optical device, the light source 11 can be turned on. Figure 5d and Figure 5e The image shown can also be interpreted as the user wearing the device in a lying or prone position; please refer to the corresponding image for reference. Figure 6d As shown.
[0061] In another specific embodiment, Figure 5f and Figure 5g The angle α between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is an obtuse angle, indicating that the orientation 101 of the opening 101 relative to the ground in three-dimensional space is facing away from the ground. That is, the head-mounted optical device is in the second posture at this time. In this posture, the light source 11 is turned off regardless of whether the first sensor 12 detects that the user is wearing the head-mounted optical device. Figure 5f and Figure 5g This can also be interpreted as the user wearing the device with their head tilted back excessively or with their head tilted back excessively.
[0062] Figure 5hThe angle α between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is a straight angle (180°). Although it is perpendicular to the ground, the orientation 1010 of the opening 101 in three-dimensional space is still facing away from the ground. That is, the head-mounted optical device is in the second posture at this time. The head-mounted optical device is in a fully flipped state. In this posture, regardless of whether the first sensor 12 detects whether the user is wearing the head-mounted optical device, the light source 11 is turned off. Figure 5h The image can also be interpreted as the user wearing the garment in a tilted-up or upside-down position.
[0063] Considering the user's actual wearing posture, continue to refer to Figures 6a-6d This embodiment explains in detail the possible first postures corresponding to the head-mounted optical device. Specifically, when the user wears the head-mounted optical device... Figure 6a The user's upper body is perpendicular to the ground and their eyes are looking straight ahead. At this time, the angle α between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is 0°. That is, at this time, the orientation 1010 of the opening 101 relative to the ground in three-dimensional space is pointing towards the ground. At this time, the head-mounted optical device is in the first posture, and the light source 11 can be turned on in this posture.
[0064] When the user wears this head-mounted optical device Figure 6b The user's upper body is perpendicular to the ground, but their head is slightly tilted up and their eyes are looking forward. At this time, the angle α between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is an acute angle. Although it is not perpendicular to the ground, the orientation 1010 of the opening 101 in three-dimensional space is still pointing towards the ground. At this time, the head-mounted optical device is in the first posture, and the light source 11 can be turned on in this posture.
[0065] When the user wears this head-mounted optical device Figure 6c The user's upper body is perpendicular to the ground, but their head is slightly lowered and their eyes are looking down. At this time, the angle α between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is an acute angle. Although it is not perpendicular to the ground, the orientation 1010 of the opening 101 in three-dimensional space is still pointing towards the ground. At this time, the head-mounted optical device is in the first posture, and the light source 11 can be turned on in this posture.
[0066] When the user wears this head-mounted optical device Figure 6dThe user's upper body is parallel to the ground and their eyes are looking straight ahead, meaning the user is lying down or prone. At this time, the angle α between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is a right angle (90°), and the opening 101 is parallel to the ground. In this three-dimensional space, the orientation 1010 of the opening 101 relative to the ground can be understood as parallel to the ground. At this time, the head-mounted optical device can still be in the first posture (which can be used as a supplement to the first posture). In this posture, the light source 11 can be turned on.
[0067] Furthermore, in a further embodiment, only when the angle between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground exceeds a preset value is it considered that the orientation 1010 of the opening 101 in three-dimensional space is facing away from the ground. That is, the head-mounted optical device is in a second posture at this time. In this posture, the light source 11 is turned off regardless of whether the first sensor 12 detects that the user is wearing the head-mounted optical device. Figure 5f and Figure 5g This can also be interpreted as the user wearing the device with their head tilted back excessively or with their head tilted back excessively.
[0068] Specifically, when the angle between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is any value in [135°, 180°], the head-mounted optical device is in a second posture. In this posture, the light source 11 is turned off regardless of whether the first sensor 12 detects that the user is wearing the head-mounted optical device. When the angle between the orientation 1010 of the opening 101 and the vertical line 2020 of the ground is any value in (90°, 135°), although the orientation 1010 of the opening 101 in three-dimensional space is opposite to the ground, the head-mounted optical device can still turn on the light source 11. The posture of the head-mounted optical device at this angle can be used as a supplement to the first posture.
[0069] Based on the above embodiments, it should also be noted that the head-mounted optical device includes a first sensor 12, a second sensor 13, a control circuit 15, and an execution unit 16. The control circuit 15 can only determine the activation of the light source 11 when the first sensor 12 detects that the user is wearing the head-mounted optical device and the second sensor 13 detects that the head-mounted optical device is in a first posture. After the control circuit 15 determines that the light source 11 is activated, the execution unit 16 can correspondingly activate the light source 11. Conversely, when the first sensor 12 detects that the user is not wearing the head-mounted optical device, and / or when the second sensor 13 detects that the head-mounted optical device is in a second posture, the control circuit 15 can determine the deactivation of the light source 11. After the control circuit 15 determines that the light source 11 is deactivated, the execution unit 16 can correspondingly deactivate the activated light source 11, or the execution unit 16 can ensure that the deactivated light source 11 remains in a deactivated state. The above describes the internal control and execution process of the head-mounted optical device.
[0070] In another specific embodiment, alternatively, reference continues. Figure 3 The head-mounted optical device also includes a communication unit 14, which is connected to a mobile terminal. The communication unit 14 is used to transmit the wearing status detected by the first sensor 12 and / or the orientation 1010 of the opening 101 detected by the second sensor 13 to the mobile terminal, and to receive feedback data from the mobile terminal.
[0071] Specifically, this embodiment essentially achieves external control of the head-mounted optical device by adding a communication unit 14. This not only improves the operability of the head-mounted optical device but also enhances user selectivity, meets individual user needs, and improves the user experience. The head-mounted optical device also includes a communication unit 14 that communicates with a mobile terminal. That is, the head-mounted optical device can communicate with an external mobile terminal, allowing the user to operate the head-mounted optical device on the mobile terminal. For example, the communication unit 14 and the mobile terminal can communicate wirelessly via Bluetooth, WiFi, Zigbee, or other wireless connection methods. In this case, the communication unit 14 can transmit the wearing status detected by the first sensor 12 and / or the orientation 1010 of the opening 101 detected by the second sensor 13 to the mobile terminal, which then determines whether the light source 11 is turned on or off.
[0072] In other words, the mobile terminal can determine that the light source 11 is turned on only when the first sensor 12 detects that the user is wearing the head-mounted optical device and the second sensor 13 detects that the head-mounted optical device is in a first posture. After the mobile terminal determines that the light source 11 is turned on, it can send feedback data to the head-mounted optical device through the communication unit 14 so that the execution unit 16 can turn on the light source 11 accordingly. Conversely, when the first sensor 12 detects that the user is not wearing the head-mounted optical device, and / or the second sensor 13 detects that the head-mounted optical device is in a second posture, the mobile terminal can determine that the light source 11 is turned off. After the mobile terminal determines that the light source 11 is turned off, it can send feedback data to the head-mounted optical device through the communication unit 14 so that the execution unit 16 can turn off the turned-on light source 11 accordingly, or the execution unit 16 can keep the unturned light source 11 always in a turned-off state.
[0073] Furthermore, during the communication between this head-mounted optical device and an external mobile terminal, for example, the user can control the output of the light source 11 via the mobile terminal, including one or more of the following: the type of light source 11, the color of the light source 11, the output power of the light source 11, the output duty cycle of the light source 11, and the working duration of the light source 11, thereby achieving the purpose of treatment or use. That is, while using the head-mounted optical device, the user can also adjust the output of the light source 11 of the head-mounted optical device in real time via the mobile terminal, or adjust or change the scheme during use. Ultimately, all of these adjustments are sent to the head-mounted optical device in the form of instruction information, and the output of the light source 11 is ultimately controlled and executed by the execution unit 16 of the head-mounted optical device.
[0074] Optionally, the light source 11 includes one or any combination of red light, blue light, green light, yellow light or infrared light.
[0075] Specifically, the light source component may include multiple light sources 11, and the light source type corresponding to the light source 11 may be one or any combination of red light, blue light, green light, yellow light, or infrared light. Specifically, the light source 11 corresponding to red light or infrared light can promote blood circulation and improve oily or acne-prone skin; the light source 11 corresponding to blue light can improve the opening and closing of pores; the light source 11 corresponding to green light can promote the restoration of normal skin vitality; and the light source 11 corresponding to yellow light can improve tissue repair and reduce inflammation. The light source type corresponding to the light source 11 in this embodiment can be determined according to actual needs and is only an example, not a limitation. Furthermore, exemplarily, the light source 11 may include multiple light sources 11 arranged in an array. Optionally, the light source 11 may include other light sources such as laser light sources or LED light sources, as long as they meet the product design requirements of the head-mounted optical device.
[0076] In this way, users can interact with and use the head-mounted optical device through mobile terminals. Users can remotely operate the head-mounted optical device through mobile terminals, which not only improves the linkage and interactivity between the head-mounted optical device and the mobile terminal, but also allows users to select appropriate optical solutions or lighting functions according to their actual situation, thereby meeting users' personalized and diversified usage needs, improving the user experience, and achieving the expected results.
[0077] Optionally, continue to refer to Figures 1-4 The inner wall 100 of the housing 10 of the head-mounted optical device can be further divided into multiple optical zones 103. For any one of these optical zones 103, the emitted light from the light source 11 corresponding to each optical zone 103 can be emitted to the outside through the light-transmitting area. For example, the light source type, light power, and other parameters of the emitted light from the light source 11 corresponding to each optical zone 103 can be the same or different. It is understood that this embodiment does not impose specific requirements or special limitations on the number of optical zones 103, the number of light sources 11 in the corresponding optical zones 103, or the light source type of the light sources 11 within the same optical zone 103. These can be set and selected according to actual needs.
[0078] Furthermore, this embodiment does not impose specific requirements or limitations on the arrangement of the optical partitions 103 corresponding to the head-mounted optical device, the size of each optical partition 103, or the division relationship between adjacent optical partitions 103. These can be set and selected according to actual needs. It is understood that the purpose of forming multiple optical partitions 103 in this head-mounted optical device is to ensure that light acts on different areas of the human body in a targeted manner. For example, taking an optical hair cap as an example, the bald areas on the head of people with hair loss vary, therefore the light energy irradiation area also needs to be targeted. Simply put, light energy is provided to the bald areas, while no light energy or less energy is provided to the non-bald areas, with the aim of providing targeted illumination. For example, taking an optical hair cap as an example, the optical partition 103 may include an optical partition 103 corresponding to the two sideburn areas when the user wears it, an optical partition 103 corresponding to the middle forehead area when the user wears it, an optical partition 103 corresponding to the top of the head area when the user wears it, an optical partition 103 corresponding to the back of the head area and two lateral areas when the user wears it, and the lateral areas are located between the sideburn area and the back of the head area. This embodiment is only an example and is not limited.
[0079] The head-mounted optical device not only divides the optical space into multiple optical zones 103, but also sets a temperature sensor 17 in each optical zone 103. Specifically, the temperature sensor 17 is set on the inner side of the inner surface wall 100 and is used to detect the temperature of the light source 11 corresponding to the optical zone 103.
[0080] First, it should be noted that when the light source 11 of this head-mounted optical device is working, its light energy acts on the user's beauty or physiotherapy area. As the light source 11 continues to operate, heat accumulates at this area. When this heat accumulation exceeds a threshold, it will cause an unpleasant user experience and may even burn the skin. Therefore, temperature detection and control are crucial aspects of this optical electronic device. For example, taking an optical hair cap as an example, due to the structural characteristics of the optical hair cap, when the user uses it, the cavity of the hair cap and the user's head form a relatively enclosed space. Furthermore, because the light source 11 continuously accumulates heat when outputting light energy, the temperature within this relatively enclosed space will continuously rise. This will not only reduce the working efficiency of the head-mounted optical device but also cause the user to experience unpleasant sensations such as burning.
[0081] Specifically, the temperature sensor 17 is located on the inner side of the inner wall 100. The temperature sensor 17 can detect the temperature of the light source 11 corresponding to the optical partition 103. For example, the temperature sensor 17 and the control circuit 15 can be connected via a communication bus. The temperature of the light source 11 corresponding to the optical partition 103 detected by the temperature sensor 17 can be sent to the control circuit 15. The control circuit 15 can compare the received temperature of the light source 11 corresponding to the optical partition 103 with a first temperature threshold. When the temperature of the light source 11 corresponding to the optical partition 103 exceeds the first temperature threshold, the control circuit 15 can control the output of the light source 11 at the optical partition 103, or at the optical partition 103 and other optical partitions 103 adjacent to the optical partition 103, to be reduced or turned off, or even paused, via the execution unit 16. This ensures the user experience and avoids discomfort such as burning caused by excessively rapid temperature rise in local areas. On the other hand, the overheating of the light source 11 will not only affect its service life, but may also affect the safety of the head-mounted optical device.
[0082] For example, the temperature sensor 17 can also communicate with an external mobile terminal through the communication unit 14. The temperature of the light source 11 corresponding to the optical partition 103 detected by the temperature sensor 17 can be sent to the mobile terminal. The mobile terminal can compare the received temperature of the light source 11 corresponding to the optical partition 103 with a first temperature threshold. When the temperature of the light source 11 corresponding to the optical partition 103 exceeds the first temperature threshold, the mobile terminal can control the output of the light source 11 at the optical partition 103, or at the optical partition 103 and other optical partitions 103 adjacent to the optical partition 103, to be reduced or turned off, or even paused, through the communication unit 14 and the execution unit 16.
[0083] Furthermore, to improve the temperature detection accuracy of the head-mounted optical device, the number of temperature sensors 17 can be increased; that is, multiple temperature sensors 17 can be provided. The inner wall 100 of the housing 10 of the head-mounted optical device can also be divided into multiple optical zones 103. Each optical zone 103 can be equipped with at least one temperature sensor 17. This temperature sensor 17 can detect the temperature of the light source 11 within the corresponding optical zone 103, further improving the temperature control sensitivity of the head-mounted optical device, thereby improving its temperature accuracy and effectively preventing adverse effects on the user or device caused by excessively high temperatures. For example, when the temperature of the light source 11 in any optical zone 103 exceeds a first temperature threshold (e.g., 55°C), the output of the light source 11 in that optical zone 103, or in the optical zone 103 and other adjacent optical zones 103, is reduced or turned off. Once the temperature of the overheated optical partition 103 drops to the second temperature threshold (e.g., 40°C), the working state of the light source 11 can be restored, returning it to the operating condition before the output was reduced or the system was turned off, thus allowing the user to continue implementing the solution.
[0084] Optionally, continue to refer to Figure 3 The head-mounted optical device also includes a first timing unit 18 and a second timing unit 19. The first timing unit 18 is used to record the working time of the head-mounted optical device, and the second timing unit 19 is used to record the illumination time of the light source 11.
[0085] Specifically, the head-mounted optical device also includes a first timing unit 18 and a second timing unit 19. Exemplarily, the first timing unit 18 and the second timing unit 19 can be disposed inside or outside the housing 10. The first timing unit 18 records the operating time of the head-mounted optical device, and the second timing unit 19 records the illumination duration of the light source 11. Both the first timing unit 18 and the second timing unit 19 begin operating when the output scheme for the light source 11 corresponding to the mobile terminal is run. That is, the scheme starts running when the light source 11 is first turned on, at which time the first timing unit 18 and the second timing unit 19 are activated, and the timing stops simultaneously after the scheme ends. The first timing unit 18 times the time continuously, while the second timing unit 19 times the time continuously due to the influence of the temperature sensor 17. In other words, the first timing unit 18 keeps timing throughout the operation of the scheme, while the second timing unit 19 pauses timing when the light source 11 overheats and resumes timing after the light source 11 cools down and resumes output. The second timing unit 19 records the illumination duration of the light source 11.
[0086] For example, if the running time of the output scheme of the light source 11 corresponding to the mobile terminal is 30 minutes, it means that the illumination time of the light source 11 is 30 minutes. When the scheme starts running, both the first timing unit 18 and the second timing unit 19 start timing. During the operation of the scheme, if the light source 11 corresponding to a certain optical partition 103 experiences an overheating phenomenon, the second timing unit 19 stops timing, while the first timing unit 18 continues timing. After the overheated light source 11 resumes output, the second timing unit 19 resumes timing. When the scheme ends, the first timing unit 18 and the second timing unit 19 stop timing simultaneously. At this time, the timing duration of the second timing unit 19 is the illumination time of the light source 11 (that is, the running time of the scheme, i.e., 30 minutes), while the timing duration of the first timing unit 18 is the running time of the scheme (i.e., 30 minutes) plus the total time for the light source 11 to cool down and resume output when it is overheated (e.g., 5 minutes). Therefore, the duration recorded by the first timing unit 18 is 35 minutes (that is, the working time of the head-mounted optical device). When the system does not experience an over-temperature pause during operation, the timing duration of the first timing unit 18 and the second timing unit 19 is the same, which is the system's operating time (i.e., 30 minutes). However, when the system experiences an over-temperature pause during operation, the timing duration of the first timing unit 18 is longer than that of the second timing unit 19. Furthermore, exemplarily, the timing durations of the first timing unit 18 and the second timing unit 19 can also be sent to the mobile terminal via the communication unit 14 for feedback and display to the user. This allows the user to clearly understand the system's operating time and the duration of over-temperature events, as well as the cooling time and number of over-temperature events when the optical partition 103 experiences over-temperature. This enhances the user's understanding of the operating conditions of the head-mounted optical device and improves the user experience.
