The lighting of the interior space of the wine cabinet usually has only two states: on or off. When the door of the wine cabinet is opened, the light is on, and when the door of the wine cabinet is closed, the light is off. Therefore, the lighting method applied to the wine cabinet is relatively simple.

Please refer to FIGS. 1-4. Some embodiments of the present disclosure provide a wine cabinet 01, which includes a box body 100, a door body 200, a first sensor 300, a second sensor 400, a lighting control part 500, and a lighting part 600. Wherein, the box 100 has at least one cavity. The door 200 is rotatably installed on the box 1001 and is configured to open or close the at least one chamber. 1-5, the first sensor 300 is installed on the box 100 and electrically connected to the lighting control part 500, and is configured to sense the first signal and transmit the first signal to the lighting control part 500. A signal indicates whether the door 200 is in an open state. The second sensor 400 is installed on the box 100 and is electrically connected to the lighting control part 500, and is configured to sense a second signal and transmit the second signal to the lighting control part 500, the second signal indicating the second sensor 400 Whether there are people in the sensing area. The lighting control part 500 is electrically connected to the lighting part 600 and has multiple control modes. The lighting control unit 500 is configured to: determine the state of the door 200 according to the first signal; when the door 200 is in the closed state, determine whether there is a person in the sensing area of the second sensor 400 according to the second signal; in the sensing area When there is a person, it is determined that the current control mode among the multiple control modes is the proximity mode; the first lighting control signal corresponding to the proximity mode is acquired, and the first lighting control signal is sent to the lighting unit 600. The lighting unit 600 is installed in the above-mentioned cavity and is configured to emit light having a first preset color temperature Ka and a first preset brightness Pa according to the first lighting control signal.

In the following, in order to clearly describe the structure of the wine cabinet 01, the first direction X, the second direction Y, and the third direction Z are introduced. As shown in Figure 1-4, the first direction X can refer to the direction parallel to the two opposite sides of the bottom surface of the wine cabinet 01 when it is placed upright, and the second direction Y can refer to the remaining two opposite sides of the bottom surface of the wine cabinet 01. Parallel direction, the third direction Z can refer to the direction perpendicular to the bottom surface. The first direction X may intersect the second direction Y, for example, the first direction X may be perpendicular to the second direction Y.

Please refer to FIGS. 1-4. The box body 100 is generally a rectangular parallelepiped structure with an opening OP on one side. In some examples, as shown in FIGS. 1 and 2, the box body 100 includes a bottom wall 101, a top wall 102, a first side wall 103, a second side wall 104 and a rear wall 105. The bottom wall 101 and the top wall 102 are perpendicular to the third direction Z and are arranged opposite each other. The first side wall 103 and the second side wall 104 are perpendicular to the first direction X and arranged opposite each other. The rear wall 105 is perpendicular to the second direction Y, It is opposite to the opening OP. In this way, the space enclosed by the top wall 102, the first side wall 103, the second side wall 104 and the rear wall 105 is a cavity. In this case, the above-mentioned cavity in the wine cabinet 01 may be a temperature control area as a whole, and the storage temperature in the temperature control area is set to be the same.

In other examples, please refer to FIG. 3 and FIG. 4, the wine cabinet 01 further includes a partition P installed on the box body 100. In this way, the partition P, the first side wall 103, the top wall 102, the second side wall 104, and the rear wall 105 enclose an upper chamber, and the partition P, the first side wall 103, the bottom wall 101, and the second side wall 104 and the rear wall 105 enclose a lower chamber. In this case, the two cavities in the wine cabinet 01 can be divided into different temperature control areas. For example, the partition P divides the cavity in the wine cabinet 01 into an upper temperature control area and a lower temperature control area. Among them, through the relevant temperature control elements in the wine cabinet 01, the upper temperature control area and the lower temperature control area can be at different temperatures. In this way, it is beneficial to store a variety of storage items with different storage temperature requirements in the wine cabinet 01, such as wine or beverages, and enrich the storage function of the wine cabinet 01.

The shape of the door body 200 is the same as the shape of the opening OP, and its size matches the size of the opening OP, and is configured to close or open the at least one cavity. There are many ways to install the door 200 and the box 100. For example, one side of the door 200 is hinged to the side of the second side wall 104 close to the opening OP through hinges and other parts, and can rotate along a line parallel to the third direction Z determined by the hinge as an axis. In addition, the door body 200 may be a transparent door body, for example. For example, the door body 200 may be a transparent glass door. In this way, the illuminating unit 600 can not only illuminate the internal space of the wine cabinet 01, but can also illuminate the exterior of the wine cabinet 01 through the door body 200, so that the wine cabinet 01 has a certain light source function for its external environment. Conducive to enhance the versatility of the wine cabinet 01.

There are many types of the above-mentioned first sensor 300, which can be selected according to actual needs.

In some examples, the first sensor 300 is a mechanical pressure sensor. In this case, as shown in FIGS. 1-4, the first sensor 300 may be embedded in the end of the top wall 102 facing the door 200, and at least partially exposed from the surface of the top wall 102 facing the door 200, for example. In this way, the exposed portion of the first sensor 300 can sense changes in pressure. The first sensor generates a first signal according to the pressure change, and transmits the first signal to the lighting control unit 500.

In other examples, the first sensor 300 is a Hall sensor, which includes a magnet 301 and a Hall element 302, wherein the Hall element 302 is electrically connected to the lighting control part 500. In this case, as shown in FIG. 4, the Hall element 302 may be disposed on the surface of the top wall 102 facing the door body 200, and the magnet 301 may be disposed on the surface of the door body 200 facing the rear wall 105 in the closed state, And when the door 200 is in the closed state, the magnet 301 and the Hall element 302 are directly facing each other. When the door 200 is in the closed state or the open state, the first sensor 300 generates a corresponding first signal based on the magnetoelectric effect between the magnet 301 and the Hall element 302 and transmits the first signal to the lighting control unit 500. It should be noted that the positions of the magnet 301 and the Hall element 302 can be interchanged.

The above-mentioned first signal refers to a signal that can reflect the state of the door 200, which is, for example, a voltage signal or a current signal.

For example, when the first sensor 300 is a mechanical pressure sensor, when the door 200 is closed, the exposed portion of the first sensor 300 is in contact with the door 200, and therefore bears a greater pressure. At this time, the first sensor 300 generates a low-level signal based on the pressure. When the door body 200 is opened, the exposed part of the first sensor 300 has no contact with the door body 200 and therefore does not bear pressure. At this time, the first sensor 300 generates a high-level signal.

For another example, when the first sensor 300 is a Hall sensor, when the door 200 is closed, the magnet 301 in the first sensor 300 and the Hall element 302 are directly facing each other, and the distance between them is the closest. The effect is the strongest. At this time, the first sensor 300 generates a low-level signal based on the strong magnetoelectric effect. When the door 200 is opened, the magnet 301 and the Hall element 302 in the first sensor 300 are no longer directly facing each other, and the distance between the two becomes larger, and the magnetoelectric effect becomes weaker. At this time, the first sensor 300 generates a high-level signal based on the weak magnetoelectric effect.

It is easy to understand that the aforementioned low-level signal or high-level signal is the aforementioned first signal. According to the first signal, the state of the door 200 can be determined. Here, the state of the door body 200 includes an open state and a closed state. For example, the first signal is a high-level signal, which indicates that the door 200 is in an open state; the first signal is a low-level signal, which indicates that the door 200 is in a closed state. In addition, according to the first signal, the opening time of the door 200 can also be obtained. For example, the duration of a single high-level signal represents the opening duration of the door 200, and the duration of a single low-level signal represents the closing duration of the door 200.

In the above-mentioned embodiment, the first sensor 300 generates a high-level signal when the door 200 is opened, and generates a low-level signal when the door 200 is closed. Of course, the first sensor 300 can also generate a low-level signal when the door 200 is opened, and a high-level signal when the door 200 is closed. At this time, the duration of a single low-level signal indicates the duration of the door 200 Open time.

The above-mentioned second sensor 400 may be a human body proximity sensor (also called a non-contact proximity sensor) based on principles of infrared, ultrasonic, infrared pyroelectric, capacitive, etc. The second sensor 400 generates different types of second signals when there are no people and when there are people in its sensing area, and transmits the second signals to the lighting control part 500. Referring to FIG. 5, the sensing area Ar is usually a spherical area with a radius r centered on the point where the second sensor 400 is located. The size of the radius of the spherical area is related to the performance of the second sensor 400. For example, the radius r of the sensing area Ar corresponding to the second sensor 400 is approximately 2 m.

The location of the second sensor 400 can be selected according to actual needs. For example, referring to FIGS. 1 and 2, the second sensor 400 is a sensor based on ultrasonic technology, which may be disposed on the surface of the top wall 102 facing the door body 200. Or, referring to FIGS. 3 and 4, the second sensor 400 may be disposed on the surface of the baffle PB between different chambers facing the door body 200. In some examples, the material of the portion of the door 200 that is directly opposite to the second sensor 400 when the door 200 is in the closed state is a non-metallic material, such as an acrylic plate, etc., so that the smooth realization of the sensing function of the second sensor 400 can be ensured.

The above-mentioned second signal may be a voltage signal or a current signal. For example, when there is no person present in the sensing area Ar of the second sensor 400, the second sensor 400 generates a low level signal; when there is a person present in the sensing area Ar of the second sensor 400, the second sensor 400 generates a high level signal. Signal. Of course, the second sensor 400 may also generate a high-level signal when there is no person in its sensing area Ar; and when there is a person in its sensing area Ar, it may generate a low-level signal.

It is easy to understand that the lighting control unit 500 can determine whether there is a person in the sensing area Ar of the second sensor 400 based on the received second signal.

The foregoing embodiment is described by taking the second signal as a voltage signal as an example. Of course, the second signal can also be a current signal. When the second signal is a current signal, the working principle of the second sensor 400 is similar, and will not be repeated here.

The above-mentioned lighting control unit 500 may be an electronic component with data storage and processing functions, such as a central processing unit (Central Processing Unit, CPU for short), a processor, a microcontroller unit (Microcontroller Unit, MCU), and so on. The installation position of the lighting control unit 500 can be determined according to actual needs, which is not limited in the embodiment of the present disclosure. For example, the lighting control part 500 may be an electric control board that controls the operation of the entire wine cabinet 01, which is embedded in the top wall 102, that is, the lighting control part 500 is wrapped by the top wall 102 without being exposed.

The above-mentioned control mode refers to a manner in which the lighting control unit 500 controls the lighting unit 600 to perform corresponding lighting through a specific lighting control signal. Each control mode corresponds to a set of lighting control signals, and the corresponding lighting control signals for any two of the above-mentioned multiple control modes can be the same or different, which can be selected according to actual needs, which is not limited in the embodiment of the present disclosure. .

The aforementioned current control mode refers to the control mode of the lighting control unit 500 when the wine cabinet 01 is currently running. The current control mode is any one of the above-mentioned multiple control modes.

The above-mentioned first lighting control signal refers to a signal for controlling the lighting unit 600 to emit light corresponding to the first preset color temperature Ka and the first preset brightness Pa in the proximity mode, and it is, for example, a voltage signal or a current signal. Here, it should be understood that the color temperature is a scale representing the light color of the light source, and the unit is Kelvin (K). According to the different color temperature, the light emitted by the light source can be divided into cold light and warm light. In some embodiments, light with a color temperature in the range of 5000K to 7000K is defined as cold light, and light with a color temperature in the range of 2500K to 2700K is defined as warm light.

The above-mentioned illuminating part 600 is a lighting electronic component that can emit light of corresponding color temperature and brightness according to different lighting control signals. That is, the illuminating part 600 can emit warm light or cold light, and the luminous brightness is adjustable. The lighting unit 600 is, for example, an element including at least one LED, an element including at least one organic light emitting diode (OLED), active matrix quantum dot light emitting diodes (Quantum Dot Light Emitting Diodes, QLEDs for short), and the like.

The above-mentioned first preset color temperature Ka refers to the color temperature of the light emitted by the lighting unit 600 in the proximity mode. For example, the value of the first preset color temperature Ka may be preset and stored in the lighting control unit 500, and the value of the value may be It is selected according to actual needs, and the embodiment of the present disclosure does not limit this. For example, the value of the first preset color temperature Ka is 2700K.

The aforementioned first preset brightness Pa refers to the brightness of the light emitted by the lighting unit 600 in the proximity mode. The value of the first preset brightness Pa, for example, may be preset and stored in the lighting control unit 500, and the value of the value may be selected according to actual needs, which is not limited in the embodiment of the present disclosure. For example, the value of the first preset brightness Pa is 50 nits.

In order to more clearly explain the lighting control process of the wine cabinet 01 in the proximity mode, the process will be described in detail below. Please refer to FIG. 15 and FIG. 21. The lighting control method includes S10 to S70.

S10, the lighting control unit 500 receives the first signal sent by the first sensor 300 and the second signal sent by the second sensor 400. The first signal indicates whether the door 200 is in an open state. The second signal indicates whether there is a person in the sensing area Ar of the second sensor 400.

For example, the first sensor 300 is a mechanical pressure sensor or a Hall sensor. The above-mentioned first signal is, for example, a voltage signal reflecting the open or closed state of the door 200. For example, the first sensor 300 generates a high-level signal when the door 200 is opened, and a low-level signal when the door 200 is closed. The second sensor 400 may be a human body proximity sensor based on the principles of infrared, ultrasonic, infrared pyroelectric, capacitive and the like. The second signal is a voltage signal. For example, when there is no person present in the sensing area Ar, the second sensor 400 generates a low-level signal; when there is a person present in the sensing area Ar, the second sensor 400 generates a high-level signal.

S20, the lighting control unit 500 judges the state of the door 200 according to the first signal.

For example, in the previous step, the first signal received by the lighting control unit 500 is a low-level signal. Based on the first signal, the lighting control unit 500 determines that the door 200 is in the closed state.

S30: When the door 200 is in the closed state, the lighting control unit 500 determines whether there is a person in the sensing area Ar of the second sensor 400 according to the second signal.

For example, in the previous step, the lighting control unit 500 has determined that the door 200 is in the closed state, and the second signal it receives is a high-level signal. The lighting control unit 500 determines that there is a person in the sensing area Ar of the second sensor 400 based on the second signal.

S40: When there is a person in the sensing area Ar, the lighting control unit 500 determines that the current control mode among the multiple control modes is the proximity mode.

Here, the current control mode refers to the control mode of the lighting control unit 500 when the wine cabinet 01 is currently operating. It is easy to understand that the current control mode is one of the multiple control modes of the lighting control unit 500. The multiple control modes include a proximity mode.

For example, in the previous step, it has been determined that there is a person in the sensing area Ar, and the lighting control unit 500 determines that the current control mode is the proximity mode.

S50: The lighting control unit 500 obtains the first lighting control signal corresponding to the proximity mode.

Here, the first lighting control signal refers to a signal used to control the lighting unit 600 to emit light corresponding to the first preset color temperature Ka and first preset brightness Pa in the proximity mode, which is, for example, a voltage signal or a current signal. For example, the first lighting control signal acquired by the lighting control unit 500 is a 3V voltage signal.

S60, the lighting control unit 500 sends the first lighting control signal to the lighting unit 600.

For example, the lighting control unit 500 transmits the above-mentioned 3V voltage signal to the lighting unit 600.

S70: The lighting unit 600 emits light having a first preset color temperature Ka and a first preset brightness Pa according to the first lighting control signal.

For example, the value of the first preset color temperature Ka is 2700K, and the value of the first preset brightness Pa is 50 nits. In this way, the lighting unit 600 emits light with a color temperature of 2700K and a brightness of 50 nits based on the received voltage signal of 3V.

At this point, the lighting control process of the wine cabinet 01 in the proximity mode is completed.

It can be seen from the above that in the wine cabinet 01 provided in the above embodiment, the lighting control unit 500 can judge the status and status of the door 200 in real time through the first signal detected in real time by the first sensor 300 and the second signal detected in real time by the second sensor.

In addition, the above-mentioned second threshold is a numerical value representing the duration, and this numerical value is used to determine whether the opening duration of the door 200 satisfies a specific condition. And, the second threshold is greater than the above-mentioned first threshold. On this basis, the size of the second threshold can be selected according to actual needs, which is not limited in the embodiment of the present disclosure. For example, the first threshold is 2 minutes, and the second threshold is 10 minutes.

In order to more clearly explain the lighting control process of the wine cabinet 01 in the alarm mode, the process will be described in detail below. Please refer to Figure 18 and Figure 21. The lighting control method also includes S30c-S70c.

S30c: When the door 200 is in the open state, the lighting control unit 500 determines whether the opening time of the door 200 is less than or equal to the second threshold and greater than or equal to the first threshold.

It is easy to understand that this step is executed on the basis of S30b in the foregoing embodiment. For example, in S30b, the lighting control unit 500 has determined based on the first signal that the opening duration of the door body 200 is 5 minutes, and the opening duration is not less than the aforementioned first threshold 2 minutes. At this time, the lighting control unit 500 determines that the opening duration of the door 200 5 min is less than the second threshold value 10 min and greater than the first threshold value 2 min.

At this point, the lighting control process of the wine cabinet 01 in the alarm mode is completed.

It is easy to understand that after taking out the wine or beverage storage items from the wine cabinet 01, people forget to close the door 200 from time to time. This is not only not conducive to the good storage of wine or beverage storage items, but also easy to cause Waste of electrical energy. In the embodiment of the present disclosure, the lighting control part 500 of the wine cabinet 01 has an alarm mode, and the wine cabinet 01 provides high-brightness lighting in a short period of time in the alarm mode to attract the attention of nearby personnel, thereby reminding the personnel to close the door in time体200.

It should be noted that the duration of the above-mentioned alarm mode can be determined according to actual conditions.

In some embodiments, when the opening time of the door 200 is greater than the above-mentioned second threshold, the alarm mode is automatically released and switched to the background mode described in the above-mentioned embodiments. Such a design can remind related personnel to close the door 200 in time through the alarm mode, and can also avoid the waste of electric energy caused by long-term high-brightness lighting.

In other embodiments, when the opening time of the door 200 is greater than or equal to the second threshold, the alarm mode continues until someone closes the door 200. In this way, the good storage conditions of the wine or beverages in the wine cabinet can be ensured to a greater extent.

As described above, the aforementioned first preset color temperature Ka to fourth preset color temperature Kd and the first preset brightness Pa to fourth preset brightness Pd may be stored in the lighting control unit 500 in a preset manner. There can be multiple ways to implement the preset.

In some embodiments, referring to FIGS. 1-4, the wine cabinet 01 further includes an input part 2000 electrically connected to the lighting control part 500. The input unit 2000 is configured to: according to the first input operation, display the parameter setting interface corresponding to the corresponding control mode other than the setting mode among the multiple control modes; send a setting instruction to the lighting control unit 500; according to the second input Operation, generate the preset color temperature value K0 corresponding to the corresponding control mode; generate the preset brightness value P0 corresponding to the corresponding control mode according to the third input operation; send the preset color temperature value K0 and the preset brightness value P0 to the lighting control Department 500. The lighting control part 500 is also configured to store a preset color temperature value K0 and a preset brightness value P0.

Here, the first input operation refers to an operation applied to the input unit 2000 that can cause the input unit 2000 to display a parameter setting interface corresponding to a corresponding control mode other than the setting mode among the various control modes. In short, the first input operation is used to select the parameter setting interface corresponding to the control mode to be entered, and to send a setting instruction to the lighting control unit 500. Here, the setting instruction includes at least information corresponding to the control mode selected by the first input operation, which refers to instructing the lighting control unit 500 to enter the setting mode, and telling the lighting control unit 500 which control mode is about to be set The command of the control mode is, for example, a binary command. The second input operation refers to an operation applied to the aforementioned parameter setting interface for instructing the input unit 2000 to generate a corresponding preset color temperature value K0. The third input operation refers to an operation applied to the parameter setting interface for instructing the input unit 2000 to generate a corresponding preset brightness value P0.

The aforementioned input unit 2000 has an input function. For example, as shown in FIG. 13, the input unit 2000 is a display screen Sr with a touch function. It should be noted that the display screen Sr here can be understood as a display module that can independently display and be electrically connected with other electronic devices to exchange data. At this time, the first input operation, the second input operation, and the third input operation are all touch operations applied to the display screen Sr. The touch operation can be performed by, for example, a finger or a stylus.

For example, as shown in Fig. 13, the display screen Sr displays a selection interface. When it is necessary to set the preset color temperature K0 and preset brightness P0, click the corresponding position in the selection page, and the display screen Sr can enter the parameter setting page of the corresponding control mode, and send a setting instruction to the lighting control unit 500. Here, the click operation is the first input operation mentioned above. For example, as shown in FIG. 13, tap the area corresponding to the "background mode" in the display screen Sr with a finger, and the display screen Sr can enter the parameter setting page as shown in FIG. 14, and notify the lighting control unit 500 of the control mode to be set It is the "background mode". Referring to FIG. 14, the parameter setting page has a color temperature bar 2200, a color temperature adjustment block 2100, a brightness bar 2400, and a brightness adjustment block 2300. Among them, the leftmost end of the color temperature bar 2200 is the color temperature value corresponding to 100% cold light, and the rightmost end is the color temperature value corresponding to 100% warm light. The corresponding color temperature value transitions to the color temperature value corresponding to 100% warm light. The minimum brightness value corresponding to the brightness bar 2400 is 0% and the maximum brightness value is 100%. The brightness value corresponding to the brightness bar 2400 gradually increases from left to right. It should be noted that, here, 0% or 100% is a relative brightness value, and the aforementioned 90 nits is an absolute brightness value. Each relative brightness value corresponds to an absolute brightness value, and the corresponding relationship can be determined according to actual needs. For example, 0% corresponds to an absolute brightness value of 0nit, 100% corresponds to an absolute brightness value of 500nit, and any percentage value between 0% and 100% corresponds to an absolute brightness value between 0nit and 500nit. For another example, 0% corresponds to an absolute brightness value of 5nit, 100% corresponds to an absolute brightness value of 600nit, and any percentage value between 0% and 100% corresponds to an absolute brightness value between 5nit and 600nit.

For example, as shown in FIG. 14, by pulling the color temperature adjusting block 2100 along the color temperature bar 2200 to an appropriate position, the display screen Sr can generate a second preset color temperature Kb of a corresponding size. In addition, the light emitted by the lighting part 600 in the wine cabinet 01 can also be set to change in real time with the pulling of the color temperature adjustment block 2100. In this way, it can be helpful for real-time feedback of the color temperature adjustment effect and improve the adjustment efficiency. Here, the pulling operation is the above-mentioned second input operation.

For example, as shown in FIG. 14, pull the brightness adjustment block 2300 to an appropriate position along the brightness bar 2400, and the display screen Sr can generate data corresponding to the second preset brightness Pb. In addition, the light emitted by the lighting part 600 in the wine cabinet 01 can also be set to change in real time as the brightness adjustment block 2300 is pulled. In this way, it can be helpful for real-time feedback of the color temperature adjustment effect and improve the adjustment efficiency. Here, the pulling operation is the third input operation.

It should be noted that, in some examples, the input unit 2000 may also be configured to receive an input operation before receiving the first input operation to enter the interface as shown in FIG. 13. That is, the input unit 2000 is usually in the off-screen state, and when receiving an operation, such as a touch operation, it enters the interface as shown in FIG. 13.

In order to more clearly explain the lighting control process of the wine cabinet 01 in the setting mode, the process will be described in detail below. Please refer to FIG. 19 and FIG. 21. The lighting control method includes S01 to S03 before S10.

S01: The lighting control unit 500 determines whether a setting command sent by the input unit 2000 is received. The setting instruction is generated in response to the first input operation.

Here, the first input operation and setting instruction are the same as those in the above embodiment, and will not be repeated here.

That is, the lighting control unit 500 will detect in real time whether it has received a setting command such as a binary command issued by the input unit 2000 during operation.

S02: When receiving the setting instruction, the lighting control part 500 enters the parameter setting state of the corresponding control mode.

For example, when the lighting control unit 500 receives a setting instruction sent by the input unit 2000, it determines that the current mode is the setting mode, and enters the parameter setting state of the background mode.

S03: The lighting control unit 500 stores the preset color temperature value K0 and the preset brightness value P0 sent by the input unit 2000. The preset color temperature value K0 is generated in response to the second input operation, and the preset brightness value P0 is generated in response to the third input operation.

Here, the second input operation and the third input operation are the same as the foregoing embodiment, and will not be repeated here. The aforementioned preset color temperature value K0 and preset brightness value P0 correspond to the control mode to be set. For example, when the control mode to be set is the "background mode", the preset color temperature value K0 and the preset brightness value P0 refer to the value of the second preset color temperature Kb and the second preset brightness, respectively. The value of Pb.

For example, the preset color temperature value K0 is 2500K, and the preset brightness value P0 is 10 nits. After receiving the above data, the lighting control unit 500 updates the current color temperature value K corresponding to the background mode to 2500K, and the current brightness value P to 10 nits, and controls the lighting unit 600 to issue a color temperature of 2500K and a brightness of 10 nits in real time. In addition, the lighting control unit 500 stores the preset color temperature value K0=2500K and the preset brightness value P0=10 nits in the correlation table corresponding to the background mode, so as to control the lighting unit 600 in the background mode next time The light with the second preset color temperature Kb=2500K and the second preset brightness Pb=10 nits is emitted.

In this way, by setting the above-mentioned input part 2000 in the wine cabinet 01, the preset color temperature value K0 and the corresponding preset corresponding to any control mode other than the setting mode can be set from the wine cabinet 01 as needed. The brightness value P0 effectively perfects the function of the wine cabinet 01.

In other embodiments, please refer to FIGS. 1-4, the lighting control part 500 is in communication connection with the terminal device MT.

Wherein, the setting information includes a preset color temperature value K0 and a preset brightness value P0 corresponding to corresponding control modes other than the setting mode among the multiple control modes.

Here, the terminal device MT may be an electronic device such as a mobile phone, a tablet computer, or a wearable device that can realize a communication connection with the wine cabinet 01. The lighting control unit 500 may include electronic components having a communication signal receiving function, such as a Wi-Fi signal receiver.

It is an instruction to instruct the lighting control unit 500 to enter the setting mode, and to inform the lighting control unit 500 which control mode is the control mode to be set. For example, binary instructions. The setting information includes at least the preset color temperature value K0 and the preset brightness value P0 corresponding to the control mode to be set.

There are many ways for the terminal device MT to generate the above-mentioned setting instructions and setting information. For example, the terminal device MT is installed with software for setting the parameters of the corresponding control mode in the wine cabinet 01, and the same interface as that shown in FIG. 13 and FIG. 14 can be called up through the software. The operation method of the above interface is the same as the above embodiment, and will not be repeated here. In this way, the terminal device MT can generate the above-mentioned setting instructions and setting information through the relevant operations applied on the above-mentioned interface, and send them to the lighting control unit 500 in the wine cabinet 01.

In order to more clearly explain the lighting control process of the wine cabinet 01 in the setting mode, the process will be described in detail below. Please refer to FIG. 20 and FIG. 21. The lighting control method includes S01' to S03' before S10.

S03', the lighting control unit 500 stores the preset color temperature value K0 and the preset brightness value P0 sent by the terminal device MT.

Here, the preset color temperature value K0 and the preset brightness value P0 correspond to the control mode to be set. For example, when the control mode to be set is the "background mode", the preset color temperature value K0 and the preset brightness value P0 refer to the value of the second preset color temperature Kb and the second preset brightness, respectively. The value of Pb.

For example, the preset color temperature value K0 is 2500K, and the preset brightness value P0 is 10 nits. After receiving the above data, the lighting control unit 500 stores it in the correlation table corresponding to the background mode, so as to control the lighting unit 600 to issue the second preset color temperature Kb=2500K and the second preset in the background mode next time. Light with brightness Pb=10 nits.

In this way, through mobile terminal devices such as mobile phones, it is possible to remotely set the preset color temperature value K0 and the corresponding preset brightness value P0 corresponding to any control mode other than the setting mode as needed, effectively improving The function of the wine cabinet 01 improves the convenience of operation at the same time.

It should be noted that the above-mentioned input unit 2000 may also be integrated with electronic components having a communication signal receiving function, such as a Wi-Fi signal receiver, so as to establish a communication connection with the above-mentioned terminal device MT. In this way, the setting instruction and setting information sent by the terminal device MT may also be received by the input unit 2000 and then transmitted to the lighting control unit 500.

The cold-color light source 621 is configured to emit light according to the cold-color lighting control signal. The warm color light source 622 is configured to emit light according to the warm color lighting control signal.

Here, the cold light source 621 refers to a light source whose color temperature of the emitted light is in the range of 5000K to 7000K. For example, the color temperature of the light emitted by the cold light source 621 is 5000K, 6000K, or 7000K. The warm color light source 622 refers to a light source whose color temperature of the emitted light is in the range of 2500K to 2700K. For example, the color temperature of the light emitted by the warm-color light source 622 is 2500K, 2600K, or 2700K.

The above-mentioned cold-color lighting control signal and warm-color lighting control signal independently control the cold-color light source 621 and the warm-color light source 622 to emit light.

In this way, the cold-color light source 621 and the warm-color light source 622 cooperate with each other, so that the lighting unit 600 as a whole emits light with a corresponding preset color temperature and a corresponding preset brightness.

For example, a cold light source 621 and a warm light source 622 emit light at the same time. The cold light source 621 emits light with a color temperature of 5000K and a brightness of 40 nits according to the cold lighting control signal, and the warm light source 622 emits light with a color temperature of 2600K and brightness according to the warm lighting control signal. It is 10 nits of light. The lighting unit 600 as a whole emits light with a color temperature of 3500 K and a brightness of 50 nits. It should be noted that this example is only used to schematically illustrate that light with a preset color temperature and a preset brightness can be emitted through the cooperation of the cold-color light source 621 and the warm-color light source 622, and does not constitute a strict limitation on the light-emitting principle.

In addition, the above-mentioned light source 620 may have various structures.

It should be noted that, please continue to refer to FIG. 10, each of the above-mentioned cold-color series sub-circuits 6211 can also be connected in series with a protection resistor R. Except for this, the structure of the cold light source 621 is the same as the previous example. With such a design, the current flowing through the cold color LED GC in the corresponding cold color series sub-circuit 6211 can be restricted by the protection resistor R, so as to prevent the cold color LED GC from being burned out due to excessive current.

There are many ways to electrically connect the warm color light source 622 and the lighting drive circuit 610.

For example, the multiple warm-color LEDs GW in the warm-color light source 622 may be electrically connected to the lighting driving circuit 610, respectively.

For another example, after the multiple warm-color LEDs GW in the warm-color light source 622 are serially connected in series, they are then electrically connected to the lighting drive circuit 610. Every three warm color LEDs GW are connected in series to form a warm color series sub-circuit 6221. After multiple warm color series sub-circuits 6221 are connected in parallel, they are electrically connected to the lighting driving circuit 610 through a wire.

It should be noted that, please continue to refer to FIG. 10, each of the above-mentioned warm color series sub-circuits 6221 can also be connected in series with a protection resistor R. Except for this, the structure of the warm-color light source 622 is the same as the previous example.

The warm color light source 622 is electrically connected to the lighting driving circuit 610 through the first pin 1 and the second pin 2 in the connector LK.

The cold color light source 621 includes a plurality of cold color LEDs GC electrically connected to the lighting driving circuit 610. The warm color light source 622 includes a plurality of warm color LEDs GW electrically connected to the lighting control unit 500. In addition, the plurality of cold color LEDs GC and the plurality of warm color LEDs GW are alternately and linearly arranged to form a light bar LS. The light bar LS is the light source 620 in the form of the aforementioned linear light source. The light bar LS can be installed on the light board LB in order to fix its linear form.

In still other examples, please refer to FIG. 9, the light source 620 is a surface light source. The surface light source includes, for example, a light guide plate GP, a diffusion film SF, a reflection film RF, and two light bars LS.

For example, the reflective film RF is located on the side of the light guide plate GP close to the top wall 102, and the diffusion film SF is located on the side of the light guide plate GP facing away from the top wall 102. The two opposite side surfaces SS1 and SS2 of the light guide plate GP are light incident surfaces. Each light bar LS may be the light bar LS shown in FIG. 8. The two light bars LS are arranged directly opposite to the side surfaces SS1 and SS2, respectively. In addition, the multiple LEDs in each light bar LS are located on the side of the corresponding light board LB close to the light guide plate GP, that is, the light exit side of the LED is directly opposite to the light entrance side of the light guide plate GP. In this way, the light emitted by the plurality of LEDs can be transmitted along the path shown by the arrow in FIG. 9, and finally transmitted to the internal space of the wine cabinet 01, for example, to the space between the light guide plate GP and the bottom wall 101.

When the on-off control signal voltage terminal Ts is at a high level, the fifth transistor Q5 is turned on. At this time, the light emitting state of the cold color light source 621 is controlled by the cold light control signal provided by the cold color control signal terminal Tc, and the light emitting state of the warm color light source 622 is controlled by the warm light control signal provided by the warm color control signal terminal Tw.

The warm color lighting control signal provided by the warm color control signal terminal Tw is transmitted to the control electrode of the fourth transistor Q4 through the seventh resistor R7. When the warm color lighting control signal is at a high level, the fourth transistor Q4 is turned on, and the low voltage of the ground voltage terminal GND is transmitted to the control electrode of the third transistor Q3 through the fourth transistor Q4 and the fifth resistor R5. The third transistor Q3 is turned on, and the voltage of the power supply voltage terminal Tvdd is transmitted to the warm color light source 622 through the third transistor Q3.

The third transistor Q3 is turned off. Each warm color LED GW in the warm color light source 622 does not emit light.

It is easy to understand that, since the above-mentioned cold-color lighting control signal and warm-color lighting control signal are both PWM signals, the light-emitting brightness of the cold-color light source 621 in the lighting unit 600 can be controlled by adjusting the duty cycle of the cold-color lighting control signal, and the light-emitting brightness of the cold-color light source 621 in the lighting unit 600 can be controlled, and the warm-color can be adjusted by The duty ratio of the lighting control signal controls the light-emitting brightness of the warm-color light source 622 in the lighting unit 600.
