The operation interface 26 may be a touch screen or other components with similar functions. The user can use the operation interface 26 or an electric switch to manually turn on and off the first light area 14 and the second light area 16; The first lamp area 14 and the second lamp area 16 are automatically turned on and off according to the image recognition result of the device 22 .

The mirror body 12 is a mirror element capable of reflecting images. The first lamp area 14 can be arranged beside the mirror body 12 , and the second lamp area 16 is arranged between the mirror body 12 and the first lamp area 14 . The first lamp area 14 may be composed of one or more sets of light bars, or one or more light emitting units arranged in any geometric pattern; the second lamp area 16 is also of the same or similar design. In the present invention, the first lamp region 14 may have a first light emitting angle range (as shown in the downward fan-shaped dotted line in FIG. 2 ), and the first beam axis B1 is defined as the first projection of the maximum light intensity value in the first light emitting angle range. direction (that is, the Y direction), and the first beam axis B1 may be substantially parallel to the plane normal vector V of the mirror body 12 . The second lamp area 16 has a second luminous angle range (the lateral fan-shaped dotted line shown in FIG. X direction); and the second beam axis B2 may present a specific angle with respect to the plane normal vector V. The specific included angle may be substantially equal to 90 degrees, but the practical application is not limited thereto.

The first light beam axis B1 of the first lamp area 14 can be substantially parallel to the plane normal vector V of the mirror body 12, so the first lamp area 14 can directly illuminate the target object in front of the mirror body 12; Located in front of the mirror body 12 , it can be regarded as the aforementioned target object directly illuminated by the first lamp area 14 . The second light beam axis B2 of the second lamp area 16 is substantially perpendicular to the plane normal vector V of the mirror body 12, so the second lamp area 16 will use the reflection of the mirror body 12 to project illumination light to the target in front of the mirror body 12 in the form of indirect illumination object; moreover, since the second lighting angle range of the second lamp area 16 also partially covers the front of the mirror body 12, the second lamp area 16 may also project part of the illumination light to the front of the mirror body 12 in a direct lighting manner target object.

In a possible implementation form of the present invention, the vanity mirror 10 can be equipped with an electric switch, and the user visually judges whether to turn on or off the first light area 14 or the second light area 16, or to turn on or off the first light area 14 and the second light area 16 at the same time. Second lamp zone 16. In other words, this embodiment can simply turn on and off the two light areas of the vanity mirror 10 . In another possible embodiment of the present invention, the computing processor 18 can be electrically connected to the first light area 14 , the second light area 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) the color temperature value, brightness and brightness change frequency of the first lamp area 14 and/or the second lamp area 16; the user can use the operation interface 26 Input the operation command, and the arithmetic processor 18 analyzes the operation command to translate it into a control command, so as to further adjust the color temperature value, brightness and/or brightness change of the first lamp area 14 and the second lamp area 16 with the lighting parameters selected by the operation command frequency. For example, in this embodiment, not only can the two light zones of the vanity mirror 10 be switched on and off, but also the color temperature, brightness or flickering effect of each light zone can be further adjusted.

In other possible implementations of the present invention, the vanity mirror 10 further provides a distance sensor 20 and an image sensor 22 electrically connected to the computing processor 18 . The distance sensor 20 is used to detect whether there is a target object within a predetermined range in front of the mirror body 12 . If the distance detection result of the distance sensor 20 considers that there is no target object within the predetermined range, the arithmetic processor 18 may use the distance detection result as a control instruction to selectively reduce the brightness of the first lamp area 14 and the second lamp area 16, Either turn off the first lamp area 14 and the second lamp area 16 to save power, or increase the brightness change frequency of the first lamp area 14 and the second lamp area 16 to warn that the vanity mirror 10 is still in the activated state, reminding the target object if The total power supply of the vanity mirror 10 can be turned off when not in use. If the distance detection result of the distance sensor 20 considers that there is a target object within the predetermined range, the arithmetic processor 18 can selectively turn on the first lamp area 14 and the second lamp area 16, or increase the first lamp area 14 and the second lamp area. The brightness of the lamp area 16 , or reduce or stop the brightness change frequency of the first lamp area 14 and the second lamp area 16 , so as to alleviate the user's discomfort when looking at the vanity mirror 10 .

The image sensor 22 is not only used to detect whether a target object appears within a predetermined range in front of the mirror body 12, but also can further obtain the image recognition result of the target object, and use whether the image recognition result meets a specific threshold as a control command; for example Said, the image sensor 22 can utilize facial recognition technology to judge whether the target object is facing the mirror body 12, or judge whether the target object is facing the mirror body 12 sideways; Comparison results at specific thresholds. The specific threshold can be interpreted as the number or weight of preset facial features in the image recognition result, for example, when the image sensor 22 detects facial features such as eyes, nose, mouth, and ears of a target object within a predetermined range in front of the mirror body 12 , it can be determined that the target object is facing the mirror 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 first lamp area 14 and the second lamp area 16 can be reduced or stopped. The brightness change frequency of the lamp area 14 and the second lamp area 16 .

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 is sitting sideways in front 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 Either increase the brightness of the first lamp area 14 and the second lamp area 16 , or reduce or stop the brightness change frequency of the first lamp area 14 and the second lamp area 16 . If the image sensor 22 only detects the ears 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 can be turned off. The light area 14 and the second light area 16 save power, or increase the brightness change frequency of the first light area 14 and the second light area 16 as a warning.

Please refer to FIG. 4 and FIG. 5 . FIG. 4 and FIG. 5 are schematic diagrams of illuminance changes of the vanity mirror 10 in different usage states according to the embodiment of the present invention. As shown in Figure 4, the curve C1 is the illuminance change when only the first lamp area 14 is turned on in the cosmetic mirror 10. It can be seen that the target object will get the maximum illuminance in the predetermined range in front of the mirror body 12. If the target object is far away from or close to the mirror body 12. The illuminance will be significantly reduced. For example, the illuminance is the highest at about 18cm in front of the mirror body (the illuminance is about 1145), and when it is greater than 18cm or less than 18cm, the illuminance will show a downward trend, and further, at 6cm, etc. Compared with the illuminance at 12cm or 18cm (respectively 1039, 1145), the illuminance at 12cm or 18cm (1039, 1145 respectively) has a great decrease. It may appear that the target object (makeup artist) wants to make detailed adjustments when the face is close to the mirror. But the dilemma of insufficient; curve C2 is the illuminance change when the vanity mirror 10 turns on the first lamp area 14 and the second lamp area 16 at the same time, and it can be found that the target object is in the predetermined range in front of the mirror body 12, or when it is far away from the mirror body 12. There is no obvious change in illuminance, but higher illuminance can be obtained when the target object is close to the mirror body 12. For example, the illuminance at about 6cm-18cm in front of the mirror body is greatly improved after adding the second group of light sources, and the difference in illuminance is small (For example, 1293 to 1173), the makeup wearer can obtain a uniform and bright lighting experience no matter whether the face is close to or away from the mirror, and the convenience of adjusting the detailed makeup is greatly improved. As shown in Figure 5, the curve C3 is the illuminance change of the vanity mirror 10 when only the second lamp area 16 is turned on. At this time, the illuminance obtained by the target object decreases rapidly as it moves away from the mirror body 12, and the influence on the farther away is smaller. That is, at a distance in front of the mirror body, when the second lamp area 16 is turned on, the illuminance does not change much. That is, it is defined that the front of the mirror body has a first distance (such as corresponding to 6cm), a second distance (such as corresponding to 12cm), and a third distance (such as corresponding to 18cm) that increase sequentially from the front of the mirror body to the mirror body. When the first lamp area 14 and the second lamp area 16 both project illumination light, the difference between the illuminance at the first distance, the illuminance at the second distance, and the illuminance at the third distance is smaller than the preset value, and the illuminance changes little, Relatively uniform, giving users a better experience; when the first lamp area 14 projects illuminating light and the second lamp area 16 is turned off, the illuminance at the first distance, the illuminance at the second distance, the third The illuminance at the distance increases sequentially; when the first lamp area is turned off and the second lamp area projects illumination light, the illuminance at the first distance, the illuminance at the second distance, and the illuminance at the third distance are sequentially decrease. It should be noted that the 6cm, 12cm, and 18cm in the accompanying drawings are cited in the above-mentioned first distance, second distance, and third distance as examples only. In order to illustrate that any side of the mirror body of the present invention is provided with a beam axis with a different orientation The effect brought by the first lighting area and the second lighting area is not a specific limitation on the distance, and the industry can adjust it according to actual needs.

To sum up, the vanity mirror of the present invention can selectively use a distance sensor and/or an image sensor to determine whether an unknown object in front of the mirror body is a target object or a non-target object. If the distance detection result of the distance sensor indicates that the distance between the unknown object and the mirror body is very far, it means that the vanity mirror is not in use; if the distance detection result of the distance sensor indicates that the distance between the unknown object and the mirror body is very short, The first lamp area can be turned on first, and the second lamp area can be turned on until the distance is lower than the predetermined distance threshold; if the distance detection result of the distance sensor thinks that the unknown object is close to the mirror body, but the image recognition result of the image sensor It is considered that the number of preset facial features of unknown objects is too small or the weight is low. It may be judged that the unknown object in front of the mirror is a target object sitting sideways, so the first or second light area, or the default face is still turned on. If the number of features is extremely small or the weight is extremely low, it is determined that the unknown object in front of the mirror body does not belong to the target object, and then the first light area and the second light area are turned off.

Compared with the prior art, the vanity mirror of the present invention is provided with a first light area and a second light area with beam axes having different directions on any side of the mirror body. The first light area illuminates the far end of the mirror body (in front of the mirror body), and is used to provide illumination light when the target object is slightly away from the mirror body. The second light area mainly illuminates the mirror body and is used to increase the illumination at the near end of the mirror body. It can provide sufficient lighting when the target object is very close to the mirror body, which is convenient for the user to check or adjust its detailed makeup. In addition, the vanity mirror of the present invention can be added with a distance sensor and an image sensor to provide an automatic light area adjustment function. As long as it is within the allowable range, uniform illumination can be obtained regardless of whether the user is far away from or close to the vanity mirror; the allowable range can be 0-50cm in front of the vanity mirror, but the actual application is not limited thereto.

The present invention has been described by the above-mentioned related embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention all belong to the scope of patent protection of the present invention.
