Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

Referring to fig. 1 to 3, fig. 1 is an external view of a cosmetic mirror 10 according to an embodiment of the present invention, fig. 2 is a schematic structural diagram of the cosmetic mirror 10 according to the embodiment of the present invention at a top view, and fig. 3 is a functional block diagram of the cosmetic mirror 10 according to the embodiment of the present invention. The cosmetic mirror 10 may include a mirror body 12, a first light section 14, a second light section 16, a processor 18, a distance sensor 20, an image sensor 22, a storage module 24, and an operation interface 26. In addition to the mirror body 12, the first light section 14 and the second light section 16, other units may be optional accessories for the vanity mirror 10. The operation interface 26 may be a touch screen or other devices with similar functions. The user can manually turn on and off the first light zone 14 and the second light zone 16 using the operator interface 26 or the electrical switch; alternatively, the cosmetic mirror 10 may automatically turn on and off the first and

second light sections

14 and 16 according to the distance detection result of the distance sensor 20 and/or the image recognition result of the image sensor 22.

The mirror body 12 is a mirror element capable of reflecting an image. The first lamp region 14 may be disposed adjacent to the mirror 12, and the second lamp region 16 is disposed between the mirror 12 and the first lamp region 14. The first lamp region 14 may be one or more light bars or one or more light emitting units arranged in any geometric pattern; the second lamp region 16 is also of the same or similar design. In the present invention, the first lamp section 14 can have a first light-emitting angle range (shown as a downward fan-shaped dotted line in fig. 2), the first light beam principal axis B1 is defined as a first projection direction (i.e., Y direction) of the maximum light intensity value of the first light-emitting angle range, and the first light beam principal axis B1 can be substantially parallel to the normal vector V of the plane of the mirror body 12. The second lamp region 16 has a second light-emitting angle range (shown as a lateral fan-shaped dotted line in fig. 2), and the second light beam principal axis B2 is defined as a second projection direction (i.e., X direction) of the maximum light intensity value of the second light-emitting angle range; and second beam principal axis B2 may assume a particular angle with respect to plane normal V. The specific angle may be substantially equal to ninety degrees, but the application is not limited thereto.

The first light beam principal axis B1 of the first lamp section 14 can be substantially parallel to the normal vector V of the mirror 12, so that the first lamp section 14 can project the illumination light to the target object in front of the mirror 12 in a direct illumination manner; if the user is located in front of the mirror body 12, the user can be regarded as the target object directly illuminated by the first lamp region 14. The second light beam main axis B2 of the second light section 16 is substantially perpendicular to the normal vector V of the mirror 12, so that the second light section 16 utilizes the reflection of the mirror 12 to project the illumination light to the target object in front of the mirror 12 in an indirect illumination manner; moreover, since the second light-emitting angle range of the second light region 16 also partially covers the front of the lens 12, the second light region 16 may also project part of the illumination light to the target object in front of the lens 12 in a direct illumination manner.

In one possible embodiment of the present invention, the cosmetic mirror 10 may be provided with an electrical switch, and the user visually determines whether to turn on or off the first lamp region 14 or the second lamp region 16, or to turn on or off the first lamp region 14 and the second lamp region 16 simultaneously. In other words, this embodiment simply turns on and off both light zones of the vanity mirror 10. In another embodiment of the present invention, the processor 18 can be electrically connected to the first lamp section 14, the second lamp section 16, the storage module 24 and the operation interface 26. The storage module 24 can store one or more lighting parameters, such as (but not limited to) color temperature values, brightness, and brightness variation frequency of the first lamp region 14 and/or the second lamp region 16; the user can input the operation command through the operation interface 26, and the operation processor 18 analyzes the operation command and translates the operation command into the control command, so as to further adjust the color temperature value, the brightness and/or the brightness variation frequency of the first lamp region 14 and the second lamp region 16 according to the illumination parameter selected by the operation command. For example, this embodiment can not only switch two light zones of the cosmetic mirror 10, but also further adjust the color temperature or brightness or flickering effect of each light zone.

In other possible embodiments of the present invention, the cosmetic mirror 10 further provides a distance sensor 20 and an image sensor 22 electrically connected to the processor 18. The distance sensor 20 is used to detect whether a target object exists in a predetermined range in front of the mirror body 12. If the distance detection result of the distance sensor 20 indicates that there is no target object within the predetermined range, the processor 18 may use the distance detection result as a control command to selectively decrease the brightness of the first lamp zone 14 and the second lamp zone 16, or turn off the first lamp zone 14 and the second lamp zone 16 to save power, or increase the brightness change frequency of the first lamp zone 14 and the second lamp zone 16 to alert that the vanity mirror 10 is still in the activated state, so as to alert that the target object can turn off its main power supply if the vanity mirror 10 is not used. If the distance detection result of the distance sensor 20 indicates that the target object is within the predetermined range, the processor 18 can selectively turn on the first lamp zone 14 and the second lamp zone 16, or increase the brightness of the first lamp zone 14 and the second lamp zone 16, or decrease or stop the brightness change frequency of the first lamp zone 14 and the second lamp zone 16 to alleviate the discomfort of the user looking at the cosmetic mirror 10.

The image sensor 22 can be used to detect whether a target object is present within a predetermined range in front of the mirror body 12, and can further obtain an image recognition result of the target object, and use whether the image recognition result meets a specific threshold value as a control command; for example, the image sensor 22 can determine whether the target object faces the mirror 12 or whether the target object faces the mirror 12 by using facial recognition technology; the decision that the target object is facing the mirror body 12 with a front face or a side face depends on the comparison of certain thresholds. The specific threshold can be interpreted as the number or weight of the predetermined facial features in the image recognition result, for example, when the image sensor 22 detects the facial features of the eyes, nose, mouth and ears of the target object within a predetermined range in front of the lens body 12, the target object can be determined to face the lens body 12; at this time, the first lamp area 14 and the second lamp area 16 can be turned on, or the brightness of the first lamp area 14 and the second lamp area 16 can be increased, or the brightness change frequency of the first lamp area 14 and the second lamp area 16 can be reduced or stopped.

If the image sensor 22 only detects the ears and part of the nose and mouth of the target object, it can be determined that the target object sits on the front side of the mirror body 12; at this time, the first lamp area 14 and the second lamp area 16 can still be turned on, or the brightness of the first lamp area 14 and the second lamp area 16 can be increased, or the brightness change frequency of the first lamp area 14 and the second lamp area 16 can be reduced or stopped. If the image sensor 22 detects only the ear of the target object, it can be determined that the target object faces away from the mirror body 12: at this time, the brightness of the first lamp area 14 and the second lamp area 16 can be reduced, or the first lamp area 14 and the second lamp area 16 can be turned off to save power, or the brightness change frequency of the first lamp area 14 and the second lamp area 16 can be increased as an alarm.

Referring to fig. 4 and 5, fig. 4 and 5 are schematic diagrams illustrating illumination variations of the cosmetic mirror 10 in different use states according to the embodiment of the present invention. As shown in fig. 4, the curve C1 shows the illumination variation when the cosmetic mirror 10 is turned on only in the first light zone 14, and it can be seen that the maximum illumination is obtained in the predetermined range in front of the mirror body 12 for the target object, and if the target object is far away from or close to the mirror body 12, the illumination is significantly reduced, for example, the illumination is maximum at about 18cm in front of the mirror body (the illumination is about 1145), and at more than 18cm or less than 18cm, the illumination tends to be reduced, and further, the illumination at 6cm and so on (about 654) has a great reduction amplitude compared with the illumination at 12cm or 18cm (1039 and 1145, respectively), and there is a problem that the target object (the cosmetic person) may adjust the face close to the mirror surface in detail, but the illumination is insufficient; the curve C2 shows the illumination variation when the cosmetic mirror 10 is turned on at the same time with the first and second light zones 14 and 16, and it can be seen that the illumination of the target object in the predetermined range in front of the mirror body 12 or far from the mirror body 12 has no significant variation, but the target object close to the mirror body 12 can obtain higher illumination, for example, the illumination in the front of the mirror body at about 6cm-18cm is greatly improved after the second group of light sources are added, and the illumination difference is small (for example, 1293 to 1173), so that the uniform and bright illumination experience can be obtained for the cosmetic wearer no matter the face is close to or far from the mirror surface, and the convenience in adjusting the cosmetic appearance is greatly improved. As shown in fig. 5, the curve C3 shows the illumination variation when the cosmetic mirror 10 is turned on only in the second light area 16, and the illumination obtained by the target object rapidly decreases with distance from the mirror body 12, and has less influence on the farther position, i.e. the illumination variation is not large when the second light area 16 is turned on at the farther position in front of the mirror body. That is, a first distance (e.g., corresponding to 6cm), a second distance (e.g., corresponding to 12cm), and a third distance (e.g., corresponding to 18cm) are defined to be sequentially increased from the front of the mirror body to the mirror body, and when the first lamp zone 14 and the second lamp zone 16 both project illumination light, a difference between the illumination intensity at the first distance, the illumination intensity at the second distance, and the illumination intensity at the third distance is smaller than a preset value, and the illumination intensity changes less, and is relatively uniform, thereby providing better experience for a user; when the first lamp area 14 projects illumination light and the second lamp area 16 is turned off, the illuminance at the first distance, the illuminance at the second distance, and the illuminance at the third distance sequentially increase; when the first lamp area is turned off and the second lamp area projects illumination light, the illumination intensity at the first distance, the illumination intensity at the second distance and the illumination intensity at the third distance are reduced in sequence. It should be noted that, the first distance, the second distance, and the third distance are respectively referred to as 6cm, 12cm, and 18cm in the drawings by way of example only, and in order to illustrate the effect brought by the first lamp area and the second lamp area with different directions of the light beam main axis arranged on any side of the mirror body of the present invention, the distance is not particularly limited, and the adjustment may be performed according to actual needs in the industry. In summary, the cosmetic mirror of the present invention can selectively use the distance sensor and/or the image sensor to determine whether the unknown object in front of the mirror body belongs to the target object or the non-target object. If the distance detection result of the distance sensor determines that the distance between the unknown object and the mirror body is far, the cosmetic mirror is in a non-use state; if the distance detection result of the distance sensor determines that the distance between the unknown object and the mirror body is very short, the first lamp area can be started first, and the second lamp area is started until the distance is lower than a preset distance threshold; if the unknown object is close to the mirror body according to the distance detection result of the distance sensor, but the image recognition result of the image sensor considers that the number of the preset facial features of the unknown object is small or the weight is low, the unknown object in front of the mirror body is possibly judged to be a target object sitting on the side, so that the first lamp area or the second lamp area is still turned on, or the number of the preset facial features is very small or the weight is very low, the unknown object in front of the mirror body is judged not to belong to the target object, and the first lamp area and the second lamp area are turned off.

Compared with the prior art, the cosmetic mirror provided by the utility model has the advantages that the first lamp area and the second lamp area with different pointing directions of the light beam main shaft are arranged on any side edge of the mirror body. The first light zone is directed toward the distal end of the mirror (the front of the mirror) for providing illumination light when the target object is slightly away from the mirror. The second lamp area mainly irradiates to the lens body, is used for improving the illumination intensity of the near end of the lens body, can provide sufficient illumination light when a target object is very close to the lens body, and is convenient for a user to check or adjust the fine makeup of the user. In addition, the cosmetic mirror of the present invention can be added with a function of providing automatic light area adjustment by using a distance sensor and an image sensor. As long as the illumination intensity is within the allowable range, the uniform illumination intensity can be obtained no matter the user is far away from or close to the cosmetic mirror; the allowable range can be 0-50 cm before the cosmetic mirror, but the practical application is not limited thereto.

The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the utility model. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
