Description

{Cosmetic case adjusting brightness of an equipped lighting adaptively and method for the case}

The present invention relates to a cosmetic case provided with a lighting lamp for makeup using the contained contents and a lighting control method for the case.

In general, once makeup is applied, the condition is not maintained all day, and it is necessary to frequently fix and supplement it several times a day. In addition, after a special activity such as eating or exercising, it is common to check the state of makeup on the lips and face while looking in the mirror, and to fix the affected area as desired if discoloration or discoloration occurs. A 'compact' or 'cushion' that contains cosmetics and a mirror in a case that is easy to carry, so that an individual can easily do it in cases where makeup needs to be partially renewed or corrected in a place other than a private space such as home. ' products are being offered.

These cosmetics have a structure that is opened and closed by a cap while containing the contents and makeup tools required for makeup, and since a mirror is attached to the inner bottom of the cap, an individual opens the cap when necessary and uses the mirror to open the desired part of the face. You can apply or apply the contents to the face using a makeup tool while looking at it, so you can easily apply makeup regardless of the location.

However, although there is a convenient point that makeup can be applied anywhere, there is still a problem that makeup cannot be properly corrected or supplemented if the lighting is weak or dark in the place. In consideration of this point, a cosmetic case provided with a mirror and a lighting device has been proposed.

However, the lighting device of the cosmetic case proposed so far is for simply brightening the face in a dark environment, so when the user partially corrects or supplements the makeup using the lighting lamp, the desired makeup tone is maintained as a whole naturally. may become impossible. For example, if a cosmetic case with a lighting lamp is brought too close, the color tone appearing on the face by makeup is biased toward white, and thus the user may over-paint the cosmetic ingredients in order to express the desired color tone. This may appear to others, in part, as excessive makeup.

In addition, although it is possible to conveniently correct and supplement makeup using the lighting provided in the cosmetic case, it is not the same brightness situation as when applying makeup for the first time in a day. There may be differences in color tone as the degree of makeup is different.

An object of the present invention is to provide a cosmetic case and a method for the case having a lighting lamp that is adjusted so that a part to be put on has a specified brightness when an individual puts on makeup using the contents contained therein.

In the following description of the embodiments according to the present invention and in the accompanying drawings, the same reference numerals refer to the same components unless otherwise specified. Of course, for convenience of description and help in understanding, different numbers may be assigned to the same components as necessary.

1 illustrates the appearance of a cosmetic case 10 for adaptively adjusting the brightness of lighting, according to an embodiment of the present invention. is configured to include an open body 11 and a cap 12 assembled or coupled to the body 11 in such a way that the opened upper part can be opened and closed.

And, Figure 2, according to an embodiment of the present invention, attached to the cosmetic case 10 as illustrated in Figure 1, for example, mounted or embedded in the side and / or lower end of the body 11, etc. The configuration of the control circuit unit 100 is exemplified.

In the cosmetic case 10 of FIG. 1 according to an embodiment of the present invention, on the inner bottom surface of the cap 12, preferably, a ring-type LED lighting lamp 105 is provided along the outer peripheral surface of the mirror and , is also provided with a photometric sensor 103 for measuring the brightness in front of the mirror. Of course, the LED lighting lamp 105 emits soft light by means of a diffuser plate provided.

In addition, a light emitting element 106 is provided on the side of the body 11 in the cosmetic case 10, and a switch capable of detecting whether the cap 12 is in close contact with the body 11 is in close contact Sw) is provided. The illustrated switch Sw moves in the vertical direction by the cap pressed or the force applied directly by the user and its own restoring force, but detects whether the cap 12 is in close contact with the body 11 without physical movement (e.g. For example, it may be a switch that detects whether a discharge path is formed. And, on the side of the cosmetic case 10, a terminal 108 for charging power to a battery built-in or mounted on the bottom surface of the body 11 is provided.

The lighting control circuit unit 100 of FIG. 2 may be attached to or embedded in a container or case of various cosmetics, but for convenience of explanation, it is hereinafter assumed that the type of cosmetic case illustrated in FIG. 1 is provided.

The lighting control circuit unit 100 includes a sensor unit 101 capable of electrically sensing the state of the switch while including the switch Sw provided at a portion where the cap 12 and the body 11 abut; A photometric sensor 103, such as a photo-diode, for measuring brightness through incident light, the ring-shaped LED lighting lamp 105, and the LED lighting lamp 105 are driven according to an applied value An LED driver 104 for doing so, the light emitting device 106 provided on the side of the case 10, and a communication network provided in a local area, for example, a WiFi modem 102 for accessing a WiFi network, and the An external communication network is accessed through the WiFi modem 102, along with an operation such as controlling the LED driver 104 or driving the light emitting device 106 according to an output signal from the sensor unit 101 It is configured to include a control unit 110 configured to do so.

In addition, the lighting control circuit unit 100 receives the necessary power by the battery 107 embedded in the body 11 or separately mounted. The battery 107 may be charged by receiving power from the outside through the charging terminal 108 . The electrical connection from the lighting control circuit unit 100 provided in the body 11 to the LED lighting lamp 105 provided inside the cap 12 and the photometric sensor 103 is connected to the inner wall or the cap on the body. This may be accomplished through a hinge that is connected thereto.

3 illustrates an example of a transition diagram for an internal state in an operation in which the control unit 110 of the lighting control circuit unit 100 adaptively adjusts the brightness of a lighting lamp. Hereinafter, with reference to the state transition diagram of the operation illustrated in FIG. 3 , a lighting brightness adaptive adjustment operation of the lighting control circuit unit 100 according to an embodiment of the present invention will be described in detail.

The control unit 110 of the lighting control circuit unit 100 is in the standby mode M01 in the initial state when power is applied from the battery 107 .

When the user opens the cap 12 of the case 10 to apply makeup using the contents and makeup tools contained in the cosmetic case 10, the electrical connection state of the switch Sw is changed accordingly, and the The state of the output signal of the sensor unit 101 is changed. In the configuration example of FIG. 2 , when the cap is in an open state, the switch Sw shorts the circuit line to form a path through which current flows, so that the output voltage of the sensor unit 101 is changed from Low to High. will transition to

When it is sensed that this changed signal state continues for a predetermined time (eg, 2 seconds) (S311), the control unit 110 recognizes that the cap is opened by the user from the closed state, and the LED driver 104 ) so that the LED lighting lamp 105 is turned on by applying a signal (S312). And, at the same time, the signal according to the brightness measured by the photometric sensor 103 (S313) (hereinafter referred to as a 'brightness value') is compared with a set reference value, and a signal compensating for the difference between the brightness value and the reference value is obtained. It is applied to the LED driver 104 (S314). For example, if the brightness value measured by the photometric sensor 103 is smaller than the reference value, a compensation value for increasing brightness by the difference is greater than the reference value, and a compensation value for decreasing brightness by the difference is greater than the reference value. ) to match the metered brightness value to the set reference value.

This process is repeated at regular intervals for a predetermined time, for example, 1 minute or 2 minutes, while the cap 12 is opened. This predetermined time is determined as a sufficient time for the user to start using cosmetics while concentrating while looking at the mirror.

And, preferably, the photometric sensor 103 is arranged in an appropriate position with a structure suitable for measuring the brightness of a specific part of the user staring at the mirror, for example, the forehead, the pupil, or the skin of the neck. .

In addition to the structure and location of the photometric sensor 103, for accurate photometry, as illustrated in FIG. 4A , in the mirror, the user can use his/her specific part (eg, eyes or mouth, etc.) ) is placed with a mark 41 on the area.

And, as a more specific example of the structure of the photometric sensor 103, as illustrated in FIG. 4B, when the user places a specific part of the face in the guided area as in FIG. 4A, the directional area ( For example, a guard that provides a path through which light (rf_L) reflected from the pupil, forehead, or neck can be mainly incident, while generally blocking incident light reflected from the periphery other than its directing area ( 103a) is provided to protrude from the periphery of the photometric sensor 103 . The guard 103a may have a structure that protrudes from the inner bottom surface of the cap 12 at a non-vertical angle to match the direction of the directed area, that is, the face or neck.

With such a structure and arrangement, the photometric sensor 103 generally measures the intensity of light reflected from a specific part of an individual who puts on makeup (that is, the brightness of the skin), and the control unit 110 measures the measured brightness. The brightness of the lighting is adaptively adjusted so that the value always meets the set reference value. Therefore, the user can always do under the same brightness of lighting without experiencing a difference in brightness for each place when applying makeup for the first time during the day, or when correcting or supplementing the makeup.

The above-described embodiment measures the amount of light reflected from a specific part, such as the user's face, in measuring the brightness of the lighting lamp. The reflectance may be changed by If you are wearing makeup with a higher tone than the reflectance of your skin tone when applying makeup on your bare face, the light metering value will be higher even with the same brightness of lighting. In this case, the controller 110 reduces the brightness of the LED lighting lamp 103, which may be an unintentional lighting adjustment.

Accordingly, in a preferred embodiment according to the present invention, the photometric sensor 103 has a structure and arrangement that directs a portion that is not commonly put on makeup, for example, the pupil, the neck, and the like.

In another embodiment according to the present invention, the photometric sensor 103 may be composed of a micro-miniature image pickup device and a micro lens array. In the present embodiment, as described above, the controller 110 performs image processing on the image data acquired by the photometric sensor 103 designed to point at a specific face part of the user to identify the pupil region. After that, by measuring the luminance of the white part of the pupil area, the brightness value of the current light is grasped.

The control unit 110, after adjusting the brightness of the lighting to match the set reference value, check whether the reference value, which is the standard for adjusting the lighting brightness, is a predetermined automatic standard value or a manual standard value adjusted and set by the user Then (S315), the confirmed result is shown through the light emitting device 106. For example, if a predetermined automatic standard value is applied as the reference value, the light emitting element 106 is left unlit (S316), and if the manual standard value adjusted and set by the user is applied as the reference value, the light emitting element 106 is By driving and lighting (S317), the user can recognize that the current lighting brightness is the preferred brightness set by the user. Of course, alternatively, the light emitting device 106 may be distinguished by different lighting colors.

The automatic standard value is a value confirmed to be the most common and appropriate for applying makeup, and is preset in the control unit 110 .

In another embodiment according to the present invention, the control unit 110 obtains the information currently set for the automatic standard value by requesting a specific server in a remote location through the WiFi modem 102, and then lighting as described above can be applied to control.

In an embodiment according to the present invention, the automatic standard value may be applied differently depending on weather. In this embodiment, when the control unit 110 requests the information on the automatic standard value from the specific server through the WiFi modem 102, the specific server checks the sender IP address of the request message and the IP address After identifying the assigned area, check the weather of the identified area from other servers that provide such information.

And when the weather in the area is confirmed, the specific server selects an automatic standard value designated as suitable for the weather, and transmits it as a response message to the lighting control circuit unit 100 requesting the automatic standard value. For example, when the weather is 'rain', an automatic standard value with a lower brightness than when it is 'sunny' is selected and provided as a response message.

The response message is received by the control unit 110 through the WiFi modem 102, and the control unit 110 extracts automatic standard value information from the response message and sets the automatic standard value as a reference value.

On the other hand, as described above, the control unit 110 adjusts the lighting so that the brightness value matching the reference value is metered as the cap 12 is opened, and the user sets whether the lighting adjustment is based on the automatic standard value. After indicating whether or not it is according to the manual standard, it enters the 'make-up mode' (M02) and waits.

In the makeup mode M02, the control unit 110 checks whether there is an input from the user or whether the user finishes makeup and the cap 12 is completely closed.

In one embodiment according to the present invention, in order not to provide a separate input means (button, touch sensor, etc.) for user input in the cosmetic case 10, the switch Sw is used as a means for user input. use. In this embodiment, when the switch Sw is pressed, the signal of the state corresponding to the step of the cap from the sensor unit 101 (the signal corresponding to Low in the example of FIG. 2 ) is short (for example, If it lasts less than 0.5 seconds), the control unit 110 recognizes that it is according to the user's pressing, not the closing of the cap.

As such, when there is a user input in the makeup mode (M02) (S321), the controller 110 first changes the currently applied reference value according to the user's input. For example, the current reference value is increased by a predetermined interval for every number of user inputs, and when the number of inputs exceeds the limit value, the reference value is increased by a predetermined interval starting from the lowest changeable lower limit value. And, even while the change of the reference value continues, the control unit 110 applies a signal to the LED driver 104 so that the brightness value obtained by photometry of the photometric sensor 103 matches the changed reference value. , so that the illumination of the luminous intensity that meets the standard value being changed (S322).

In this way, if the user determines that it is appropriate for the brightness of the lighting lamp that changes whenever the switch Sw is pressed, further pressing of the switch is stopped, and accordingly, the lighting of the brightness desired by the user is finally set. When the reference value is changed to a value designated by the user in this way, the control unit 110 sets the changed setting value as a manual standard value and sets a flag indicating that the current brightness of the lighting lamp is based on the manual standard value. The state to be displayed through the light emitting device 106 is determined by referring to this flag in the step of confirming the type of the applied reference value (S315) described above.

The control unit 110 changes the light emitting element 106 from unlit to lit, as described above, in order to indicate that the standard value (ie, manual standard value) changed by the user's adjustment is the lighting of the applied brightness, or the corresponding The color is changed (S323), and it returns to the makeup mode (M02) again.

When the user uses the corresponding cosmetics again afterward, through the display state of the light emitting device 106, the user immediately determines whether the brightness of the current lighting lamp is based on the manual standard value set by the user or the automatic standard value set automatically. can figure out

If the user wants to restore the application of the automatic standard value set automatically from the application of the manual standard value set by the user, the switch (Sw) is kept pressed for a predetermined time or longer to input the reference value initialization. By this user's operation, the control unit 110 detects that the low signal detected from the sensor unit 101 is changed to a high signal again after lasting more than a set release time (eg, 2 seconds) At the bottom ( S331 ), the reference value applied to the lighting brightness adjustment is changed to a specified automatic standard value (eg, an automatic standard value received and stored from the specific server) and the flag is reset. And, at the same time, the brightness of the LED lighting lamp 105 is adjusted through the LED driver 104 so that the brightness that meets the newly set standard value as an automatic standard value is metered by the photometric sensor 103, and the light emitting element 106 For , the display state is switched to a state indicating that it is based on an automatic standard value (S332). The operation mode maintains the makeup mode (M02) as it is.

If the signal detected from the sensor unit 101 lasts for more than a specified time limit (eg, 10 seconds) (S341), it is recognized that the user has closed the cap 12 by ending the makeup using the corresponding cosmetics. and control the LED driver 104 to turn off the LED lighting lamp 105 (S342), and the operation mode is switched to the standby mode (M01).

In an embodiment according to the present invention, a plurality of manual standard values set by a user may be operated. To this end, when there is manual adjustment of the lighting brightness by the user (that is, when applying the manual standard value as a reference value accordingly), the control unit 110 controls the manual standard value list 50 of the structure as illustrated in FIG. 5 . ), and registers the set manual standard value and the set time zone together as one entry 51 in the list 50. For example, if an arbitrary manual standard value is set by the user's input at 1 pm, the time zone 1 hour before and after that time, that is, from 12 pm to 2 pm, is recorded in association with the manual standard value. put

Then, again later, by the user's input, if the applied reference value is adjusted and the manual standard value is set, it is checked whether the time point belongs to the time zone of the entry previously registered in the manual standard value list 50, and the If it belongs to the time zone, the manual standard value of the corresponding entry is replaced with a newly set manual standard value, and if there is no time zone to which the point belongs, the time zone and the adjusted reference value (that is, the newly set manual standard value) of the manual standard value list (50) is registered as a new entry (52). At this time, as illustrated in FIG. 6 , when the time zone (TZ ₂ ) of the newly registered entry overlaps with the time zone (TZ ₁ ) of the previously registered entry in some time sections 61, the overlapping time section 61 Record the time zone ( _{nTZ 1} , _{nTZ 2} ) in the manual standard value list 50 after the central time point 62 of .

In this way, when the user manually sets the brightness of the lighting lamp several times a day, the manual standard value list 50 lists a plurality of manual standard values with different time zones. In the embodiment in which the manual standard value is registered and managed together with the time zone information as described above, when the user opens the cap 12 to apply makeup with the contents of the cosmetic case 10 and a makeup tool, the control unit 110 is , it is confirmed whether the time point belongs to the time zone of any one of the entries listed in the manual standard value list 50 . If the entry for the time zone to which the time belongs is not registered, the control unit 110 controls the lighting until a brightness value that meets the current reference value (automatic standard value, or previously set manual standard value) is metered as described above. Adjust the brightness.

If an entry in the time zone to which the time of opening the cap 12 belongs is listed in the manual standard value list 50, the control unit 110 sets the entry as a reference value to which the manual standard value is applied, and the reference value A necessary signal is applied to the LED driver 105 until the brightness of the light according to the light is measured. Of course, in this case, a state indicating that the manual standard value is being applied to the light emitting device 106 is displayed.

As described above, the controller 110 may delete all entries in the manual standard value list 50 when the user inputs initialization of the reference value.

In one embodiment according to the present invention, when the user sets a manual standard value for the brightness of lighting, the weather information at the set time point is recorded in association with the set manual standard value. To this end, in this embodiment, when the user sets a manual standard value that becomes the desired light brightness through the input of the switch Sw, the control unit 110 sends the current value to the specific server through the WiFi modem 102. Ask for weather information. If weather information (eg, sunny, cloudy, rain, snow, fog, etc.) of the area where the cosmetic case 10 is located is provided from the specific server according to this inquiry, the controller 110 transmits the weather information Record the current adjusted reference value, that is, the manual standard value.

When the user re-opens the cap 12 again at some point after closing the cap 12 after finishing makeup, the control unit 110 uses the automatic standard value as a reference value to measure the reference value. While adjusting the brightness of 105, the current weather information is received by contacting the specific server through the WiFi modem 102 at the same time.

When weather information is received, the controller 110 compares the manual standard value with the stored weather information, and when the weather information matches, sets the manual standard value as a reference value, so that the brightness according to the manual standard value is metered by the LED driver The LED lighting lamp 105 is controlled through 104, and if the weather information does not match with each other, the set manual standard value is ignored and the application of the automatic standard value is maintained.

In the present embodiment, a plurality of manual standard values may be set and managed in response to different weather information. That is, when the user sets a new manual standard value, if the manual standard value for the same weather information as the weather information at that time has already been recorded, the manual standard value is replaced with the currently set manual standard value. Record the weather information along with the standard values.

Accordingly, when the cosmetic case 10 is opened, the controller 110 finds a match with the weather information received by inquiring from the specific server from the plurality of recorded weather information, and links the found weather information The manual standard value is applied as the standard value of lighting brightness. Of course, if there is no matching weather information, the brightness of the lighting is adjusted by applying the automatic standard value as described above.

In one embodiment according to the present invention, as described above, when the brightness of the lighting lamp is automatically set to the previously used brightness based on the time pattern of the user's manual adjustment of the lighting brightness or the type of weather at that time. , it is also possible to indicate to the user that the brightness is due to 'learning'. That is, the light emitting device 106 may be driven in different light-off states so that a preset automatic standard value, a manual standard value adjusted by a user, and a learned standard value can be distinguished and recognized. Here, the different light-off states refer to each state lit with different colors, each state divided into on and off, and each state divided by different lighting methods (eg, continuous lighting, flashing of different cycles). etc.) refers to all or part of it.

According to an embodiment of the present invention, as illustrated in FIG. 7 , when a plurality of light emitting devices 70 of the same color are provided, a mark indicating which reference value is currently applied to control the brightness of lighting lamps ( 71) may be appended to each light emitting device. In this embodiment, whether the reference value applied for the brightness of the lighting is automatically determined by the unique method of the lighting control circuit unit 100 (a preset reference value or a reference value obtained from a predetermined server), the user's manual adjustment The light emitting device is turned on according to whether or not it is by learning according to the user's manual adjustment as in the above-described embodiment.

When the opening of the cap is detected from the output signal of the sensor unit, a signal is applied to the driving unit to turn on the lighting lamp, and the brightness measured by the light metering unit becomes the same as the set reference value. It is configured to include a control unit to control the
The control unit inquires a remote server through the wireless modem, at least according to the weather divided into 'rain' and 'sunny', obtains a standard value of lighting brightness determined for the current area in which the case is located, and uses the standard value as the reference value. By applying, it is configured to control the brightness of the illumination lamp through the driving unit so that the brightness measured by the light metering unit is equal to the obtained illumination brightness standard value,
The obtained standard value of lighting brightness is determined according to a method in which when the weather is 'rain', the brightness is lower than when it is 'sunny'. delete The method of claim 1,
The control unit changes the reference value according to a user's input, and controls the brightness of the lighting lamp through the driving unit so that the brightness measured by the light metering unit becomes the same as the changed reference value. 4. The method of claim 3,
The control unit stores the reference value changed by the user's input together with the changed time zone, and when opening of the cap is sensed thereafter, if the opening time belongs to the stored time zone, based on the changed and stored reference value A cosmetic case that is configured to control the brightness of the lighting lamp. 4. The method of claim 3,
When the reference value is changed by a user input, the control unit inquires a remote server through the wireless modem to obtain weather information of the current area, stores it together with the changed reference value, and then detects the opening of the cap When the weather information obtained from the server through the wireless modem matches the stored weather information, the cosmetic case is configured to control the brightness of the lighting lamp based on the changed and stored reference value. 4. The method of claim 3,
Doedoe further comprising at least one light emitting element provided in the case,
The control unit distinguishes whether a predetermined standard value is applied as the reference value or a standard value changed according to a user's input is applied as the reference value by driving the at least one light emitting device in different light-emitting states A cosmetic case that is to be identified. 7. The method of claim 6,
The control unit is configured to further distinguish whether the user selects a previously used standard value and applies it as the reference value based on a pattern of time for changing the reference value or a weather type when changing the reference value, so that the at least one A cosmetic case that can drive light-emitting elements in different light-off states. The method of claim 1,
The light metering unit is directed to a specific part of the face or neck of the user looking at the mirror and has a structure that blocks light reflected outside of the directed area from being metered. In the method of adjusting the lighting of a cosmetic case,
Step 1 of detecting that the cap of the cosmetic case is opened;
a second step of turning on the lighting lamp according to the detection;
Step 3 of metering the brightness of the front of the mirror provided on the inside of the cap;
Doedoe comprising the step of controlling the brightness of the lighting lamp so that the metered value is equal to a set reference value,
Step 4 is
Step 4-1, which inquires a remote server and obtains a standard value of lighting brightness determined for the current area where the cosmetic case is located, according to the weather divided into at least 'rain' and 'sunny';
and applying the obtained standard value of lighting brightness as the reference value, and controlling the brightness of the lighting lamp so that the metered value is the same as the reference value;
The obtained standard value of lighting brightness is determined according to a method in which when the weather is 'rain', the brightness is lower than when it is 'sunny'.
