In each embodiment of the light control method, the executing body may be a light control device or a home appliance that needs to perform display light control, and for convenience of description, each embodiment is explained by using the home appliance as the executing body. The light control method comprises the following steps:

step S10, acquiring time information and ambient light intensity;

in the prior art, the backlight lamps of display panels of household appliances on the market are turned on and off by arranging a photosensitive device in an air conditioner, when the photosensitive device detects that current ambient light is brighter, the backlight lamps can be turned on to display light, and when the current ambient light is darker, a user is considered to be in a sleep state, and the backlight lamps can be turned off to display light. However, if the lighting conditions of the house are not good, the indoor light is also dark in the daytime, and even if the user is not in a sleep state at this time, the backlight lamp turns off the display light, so that the user cannot see the information displayed by the backlight lamp in the daytime.

In order to solve the technical problems that the existing light control method of the household appliance only depends on the illumination intensity to switch on and off the display light, the light control requirements under different time scenes cannot be met, and the intelligence is insufficient, the embodiment of the invention provides the light control method, aiming at controlling the display light of the household appliance according to the factors of time and the illumination intensity simultaneously so as to improve the intelligence of the light control of the household appliance.

In the present embodiment, the time information reflects the time when the ambient light intensity is acquired, for example, the time when the ambient light intensity is acquired is 22 minutes and 30 seconds at 14 hours at 30 months and 30 days in 2019, and the time information is 22 minutes and 30 seconds at 14 hours at 30 days and 30 months at 12 months and 30 days in 2019. The time information may be provided by the cloud server to the home appliance device when the home appliance device establishes the communication connection with the cloud server, which is equivalent to establishing the connection between the home appliance device and the internet when the home appliance device establishes the communication connection with the cloud server, or may be provided by a timing device with a timing function integrated with the home appliance device, or may be provided by another terminal with a timing function that establishes the communication connection with the home appliance device, and the specific acquisition mode of the time information is not limited in this embodiment.

The ambient light intensity reflects the intensity of the ambient light, and the ambient light intensity may be detected by a photosensitive element with a photosensitive function integrated in the home appliance device, or provided by another terminal with a photosensitive function in communication connection with the home appliance device.

The home appliances may be understood as home appliances that need to perform display light control, and the home appliances include, but are not limited to, air conditioners, refrigerators, televisions, fans, telephones, computers, and the like.

Step S20 of determining a turning-off intensity threshold value and a turning-on intensity threshold value corresponding to the time information;

in this embodiment, the turn-off intensity threshold refers to a critical illumination intensity value of the display light of the household electrical appliance, when the detected ambient illumination intensity is less than or equal to the turn-off intensity threshold, the display light of the household electrical appliance is turned off, the turn-on intensity threshold refers to a critical illumination intensity value of the display light of the household electrical appliance, and when the detected ambient illumination intensity is greater than or equal to the turn-on intensity threshold, the display light of the household electrical appliance is turned on.

In this embodiment, a user or an operation and maintenance person can set different extinguishing intensity thresholds and lighting intensity thresholds for different times in advance according to actual needs, or the home appliance itself can automatically set different extinguishing intensity thresholds and lighting intensity thresholds for different times according to actual conditions, which is not specifically limited in this embodiment. After the setting is completed, the extinguishing intensity threshold and the lighting intensity threshold corresponding to the time information are obtained at different times, so that after the time information is determined, the extinguishing intensity threshold and the lighting intensity threshold corresponding to the time information can be obtained.

It is understood that, for the same time information, the extinction intensity threshold corresponding to the time information is less than or equal to the lighting intensity threshold.

And step S30, controlling the display light according to the ambient light intensity, the extinguishing intensity threshold and the lighting intensity threshold.

In this embodiment, after determining the extinguishing intensity threshold and the lighting intensity threshold corresponding to the time information, the ambient light intensity is compared with the extinguishing intensity threshold and the lighting intensity threshold, the magnitude of the ambient light intensity compared with the extinguishing intensity threshold or the lighting intensity threshold is determined, and the display light of the household appliance is controlled according to the comparison result. Specifically, if the detected ambient illumination intensity is less than or equal to the extinguishing intensity threshold, the display light of the household appliance is extinguished; and if the detected ambient illumination intensity is greater than or equal to the lighting intensity threshold value, lighting the display light of the household appliance.

Further, if the detected ambient light intensity is greater than the turn-off intensity threshold and less than the turn-on intensity threshold, the display light of the household appliance is not adjusted, and the original display state of the household appliance is maintained.

The embodiment obtains the time information and the ambient light intensity; determining a turning-off intensity threshold and a turning-on intensity threshold corresponding to the time information; and controlling the display light according to the ambient illumination intensity, the extinguishing intensity threshold and the lighting intensity threshold. Different critical illumination intensity threshold values are set for different times, so that the light control of the household appliance is not only dependent on the illumination intensity of the ambient light, but also dependent on the critical illumination intensity threshold values of the display light corresponding to different times, the light control requirements under different time scenes are met, and the intelligence of the light control of the household appliance is improved.

Further, a second embodiment of the light control method according to the present invention is provided, before the step S10, the method further includes:

step S101, judging whether the household electrical appliance to be subjected to display light control is connected with a cloud server;

step S102, if not, obtaining the ambient light intensity;

step S103, controlling the display light of the household appliance according to the ambient illumination intensity, a preset extinction intensity threshold and a preset lighting intensity threshold;

if yes, go to step S10.

In this embodiment, to acquire comparatively accurate time information through the high in the clouds server, whether the equipment that at first will confirm to show light control establishes with the high in the clouds server and is connected, if, then can realize acquireing accurate time information through the high in the clouds server to control the demonstration light of household electrical appliances according to time information and illumination intensity, in order to satisfy the light control demand under the different time scenes, promote household electrical appliances's light control's intelligence.

However, if the home appliance device is not connected to the cloud server, that is, when the home appliance device cannot acquire accurate time information, the process is returned to the next step, and the display light of the home appliance device is controlled only according to the illumination intensity of the ambient light. Specifically, the ambient light intensity is acquired, the ambient light intensity is compared with a preset extinction intensity threshold and a preset lighting intensity threshold, and if the detected ambient light intensity is less than or equal to the preset extinction intensity threshold, the display light of the household appliance is extinguished; and if the detected ambient illumination intensity is greater than or equal to the preset lighting intensity threshold value, lighting the display light of the household appliance. The preset turning-off intensity threshold and the preset lighting intensity threshold are preset by a user or an operation and maintenance worker according to a need, for a situation without network connection, and this embodiment is not particularly limited.

In the embodiment, by setting the control mode of displaying the light when no network connection exists, the application scene of displaying the light control of the household appliance is increased, and the embarrassing situation that the displayed light cannot be controlled because accurate time information cannot be acquired under the condition of no network connection is avoided.

Further, the step S20 includes:

step S21, determining a target time period corresponding to the time information according to preset time period information, wherein the preset time period information comprises corresponding relations between each time information and each time period;

in this embodiment, the preset time period information includes a corresponding relationship between each time information and each time period, each time information has a corresponding time period, and according to the corresponding relationship between each time information in the preset time period information and each time period, it may be determined when the time information corresponds to the time period, the preset time period information may be manually set by a user or an operation and maintenance person according to actual needs, or may be automatically set by the home appliance device according to activity characteristics of the user or sunrise and sunset times, which is not limited in this embodiment. For example, if the user were to be 22: 00 to 7:00 on the next day was set as the night time period, and 7:00 to 22: 00 is set as the daytime period, 22: correspondence of 7:00 for 00 to day two to night time period, and 7:00 to 22: 00 is a preset time period information, and if the time information is 18: 32, and determining that the time information belongs to 7:00 to 22: 00, the target time period in which the time information is located is a daytime time period, namely the time information corresponds to the daytime time period; if the time information is 04: 23, the time information belongs to 22: 00 to 7:00 of the next day, the target time period in which the time information is located is the night time period, i.e., the time information corresponds to the night time period.

Step S22, acquiring a turning-off intensity threshold value and a turning-on intensity threshold value corresponding to the target time period;

in this embodiment, a user or an operation and maintenance person may set different extinguishing intensity thresholds and lighting intensity thresholds for different time periods in advance according to actual needs, or the home appliance itself may automatically set different extinguishing intensity thresholds and lighting intensity thresholds for different time periods according to actual conditions, which is not limited in this embodiment. After the setting is completed, different time periods have the extinguishing intensity threshold and the lighting intensity threshold corresponding to the different time periods, so that after the target time period is determined, the extinguishing intensity threshold and the lighting intensity threshold corresponding to the target time period can be obtained.

It is understood that, for the same period of time, the extinction intensity threshold corresponding to that period of time is less than or equal to the lighting intensity threshold.

Correspondingly, the step S30 includes:

and step S31, controlling the display light according to the ambient light intensity, the extinguishing intensity threshold value and the lighting intensity threshold value corresponding to the target time period.

Further, the step S31 includes:

In this embodiment, after determining the extinguishing intensity threshold and the lighting intensity threshold corresponding to the target time period, the detected ambient light intensity is compared with the extinguishing intensity threshold and the lighting intensity threshold, the magnitude of the ambient light intensity compared with the extinguishing intensity threshold or the lighting intensity threshold is determined, and the display light of the household appliance is controlled according to the comparison result. Specifically, if the detected ambient illumination intensity is less than or equal to the extinguishing intensity threshold corresponding to the target time period, the display light of the household appliance is extinguished; and if the detected ambient illumination intensity is greater than or equal to the lighting intensity threshold corresponding to the target time period, lighting the display light of the household appliance.

Further, if the detected ambient light intensity is greater than the turn-off intensity threshold corresponding to the target time period and less than the turn-on intensity threshold corresponding to the target time period, the display light of the household appliance is not adjusted, and the original display state is maintained.

In the embodiment, the user does not need to set the corresponding critical illumination intensity threshold value at each time, but only needs to set each time period, so that the setting process of the critical illumination intensity threshold value can be simplified, and the number of the corresponding relations can be reduced due to the reduction of the number of the critical illumination intensity threshold values to be set, thereby reducing the occupation amount of the memory.

Further, the step S31 includes:

In this embodiment, when it is detected that the ambient light intensity is less than or equal to the extinction intensity threshold corresponding to the target time period, the display light of the household appliance is not extinguished immediately, but the ambient light intensity is continuously monitored for a duration less than or equal to the extinction intensity threshold corresponding to the target time period, and if the duration is greater than or equal to a preset extinction duration, the display light of the household appliance is controlled to be extinguished;

correspondingly, when the ambient light intensity is detected to be greater than or equal to the lighting intensity threshold value corresponding to the target time period, the display light of the household appliance cannot be immediately lighted, but the duration that the ambient light intensity is maintained to be greater than or equal to the lighting intensity threshold value corresponding to the target time period is continuously monitored, and if the duration is greater than or equal to the preset lighting duration, the display light of the household appliance is controlled to be lighted.

The preset extinguishing time and the preset lighting time are set by a user or operation and maintenance personnel as required, the preset extinguishing time and the preset lighting time can be the same or different, and the embodiment is not limited specifically.

This embodiment is long through the maintenance that sets up illumination intensity, can avoid the frequent scintillation of the environmental light along with the sudden change of display light of equipment in short time to promote user experience, promote the bulb life of equipment simultaneously.

Further, the target time period includes a night time period, the turning-off intensity threshold corresponding to the night time period is a first turning-off intensity threshold, and the lighting intensity threshold corresponding to the night time period is a first lighting intensity threshold; the preset turning-off duration corresponding to the night time period is a first preset turning-off duration, and the preset lighting duration corresponding to the night time period is a first preset lighting duration; the step S31 includes:

in step S312, if the ambient light intensity is greater than or equal to the first lighting intensity threshold and the duration of maintaining the ambient light intensity greater than or equal to the first lighting intensity threshold is greater than a first preset lighting duration, the display light is controlled to be turned on.

In this embodiment, the target time period in which the time information is located is a night time period, the turning-off intensity threshold corresponding to the night time period is a first turning-off intensity threshold, and the lighting intensity threshold corresponding to the night time period is a first lighting intensity threshold, if the detected ambient light intensity is less than or equal to the first turning-off intensity threshold, and a duration of maintaining the ambient light intensity less than or equal to the first turning-off intensity threshold is greater than or equal to a first preset turning-off duration, the display light of the household appliance is controlled to be turned off; and if the detected illumination intensity is greater than or equal to the first illumination intensity threshold value, and the duration for maintaining the environment illumination intensity greater than or equal to the first illumination intensity threshold value is greater than or equal to a first preset illumination duration, controlling the display lamp of the household appliance to be illuminated.

In addition, the first preset turning-off duration and the first preset turning-on duration may be the same or different, and this embodiment is not limited specifically.

Further, the target time period further includes a daytime time period, the extinction intensity threshold corresponding to the daytime time period is a second extinction intensity threshold, and the lighting intensity threshold corresponding to the daytime time period is a second lighting intensity threshold; the first extinction intensity threshold is less than the second extinction intensity threshold, and the first illumination intensity threshold is less than a second illumination intensity threshold; the preset extinguishing time corresponding to the daytime time period is a second preset extinguishing time, and the preset lighting time corresponding to the daytime time period is a second preset lighting time; the step S31 includes:

step S314, if the ambient light intensity is greater than or equal to the second lighting intensity threshold value, and the duration of maintaining the ambient light intensity greater than or equal to the second lighting intensity threshold value is greater than a second preset lighting duration, controlling the display light to be turned on.

In this embodiment, the target time period in which the time information is located is a daytime time period, the turning-off intensity threshold corresponding to the daytime time period is a second turning-off intensity threshold, and the lighting intensity threshold corresponding to the daytime time period is a second lighting intensity threshold. Moreover, because the user is usually in a sleep state at night, the user is very sensitive to light at this time, and weak light can affect the sleep of the user, and the sensitivity of the user to the light intensity is inferior to that at night at daytime, therefore, the threshold of the critical light intensity corresponding to the night time is smaller than the threshold of the critical light intensity corresponding to the day time to improve the sensitivity of the light sensitive element at night, and avoid affecting the rest of the user, therefore, the second extinction intensity threshold is greater than the first extinction intensity threshold, and the second illumination intensity threshold is greater than the first illumination intensity threshold.

Because sunrise and sunset times at different periods may be different in different places, to determine the sunrise time and the sunset time, first, the location information of the home appliance is obtained, where the location information may be provided by a timing device with a positioning function integrated in the home appliance, or provided by another terminal with a positioning function that establishes a communication connection with the home appliance, or address information preset by a user or an operation and maintenance person, and this embodiment does not limit a specific obtaining manner of the location information.

After the position information and the time information are determined, sunrise time and sunset time corresponding to the position information and the time information can be acquired. A manner of acquiring corresponding sunrise time and sunset time according to the position information and the time information is that a user or an operation and maintenance person prestores a corresponding relationship between the position information and the time information and the sunrise time and the sunset time in the household electrical appliance, and after the position information and the time information are determined, the sunrise time and the sunset time corresponding to the position information and the time information can be acquired according to the corresponding relationship; still another way is to obtain the corresponding sunrise time and sunset time from the internet based on the location information and the time information when the home appliance device is connected to the internet, and this embodiment does not limit the specific obtaining manner of the sunrise time and the sunset time.

After sunrise time and sunset time are determined, dividing a night time period and a daytime time period according to the sunrise time and the sunset time, and taking the corresponding relation of the night time period, the daytime time period and the time as preset time period information. For example, if the sunrise time of 12 months in 2019 for a is 06:00, the sunset time is 18: 00, then 18 of each of the 12 months of 2019: 00 to 06:00 on the next day was set as the night time period, and 06:00 to 18: 00 is set as the daytime period, 18 for each of 12 months in 2019: correspondence of 06:00 to the next day with the night time period, and 06:00 to 18: 00 and the daytime time period as the preset time period information.

In this embodiment, the household electrical appliance automatically sets the preset time period information according to the sunrise time and the sunset time, and the user does not need to manually set the preset time period information, so that the intelligence of light control is improved.

Further, before step S21, the method further includes:

step S205, acquiring historical sleep starting time and historical sleep ending time when the user is in a sleep state;

step S206, obtaining historical illumination intensity corresponding to each historical sleep starting time, averaging the historical illumination intensity corresponding to each historical sleep starting time to obtain first illumination intensity, obtaining historical illumination intensity corresponding to each historical sleep ending time, and averaging the historical illumination intensity corresponding to each historical sleep ending time to obtain second illumination intensity;

step S207, determining a first turning-off intensity threshold and a first lighting intensity threshold corresponding to the night time period according to the first illumination intensity, and determining a second turning-off intensity threshold and a second lighting intensity threshold corresponding to the daytime time period according to the second illumination intensity.

The present embodiment is a process in which the home appliance automatically sets the lighting intensity threshold and the extinguishing intensity threshold for each time segment according to the historical sleep start time and the historical sleep end time of the user. The historical sleep start time and the historical sleep end time may be obtained by monitoring a physiological indicator of a user by a wearable device of the user, and reflect a time that the user is in a sleep state within a period of time, for example, within one month, where the time includes a start time that the user is in the sleep state, i.e., the historical sleep start time, and an end time that the user is in the sleep state, i.e., the historical sleep end time.

In this embodiment, the home appliance may record and store the illumination intensity at different times to obtain a historical illumination record. After the historical sleep starting time and the historical sleep ending time of the user are obtained, the household appliance can obtain the illumination intensity corresponding to each historical sleep starting time according to the historical illumination record, and the illumination intensity corresponding to each historical sleep starting time is averaged to obtain a first illumination intensity; the household appliance also can obtain the illumination intensity corresponding to each historical sleep ending time according to the historical illumination record, and the illumination intensity corresponding to each historical sleep ending time is averaged to obtain a second illumination intensity.

After the first illumination intensity and the second illumination intensity are obtained, a first extinction intensity threshold and a first lighting intensity threshold corresponding to the night time period are determined according to the first illumination intensity, and a second extinction intensity threshold and a second lighting intensity threshold corresponding to the day time period are determined according to the second illumination intensity.

Further, the step S207 may include:

In the present embodiment, the first illumination intensity Q1 is compared with the first preset illumination intensity X1, and if Q1 > X1, Q1 is used as the lighting intensity threshold corresponding to the night time period, and X1 is used as the extinguishing intensity threshold corresponding to the night time period; if Q1 is less than X1, taking Q1 as a light-off intensity threshold value corresponding to the night time period, and taking X1 as a light-on intensity threshold value corresponding to the night time period; when Q1 is X1, Q1 is defined as the lighting intensity threshold value for the night time zone, and X1 is defined as the turning-off intensity threshold value for the night time zone.

Comparing the second illumination intensity Q2 with a second preset illumination intensity X2, and if Q2 > X2, taking Q2 as a lighting intensity threshold corresponding to the daytime time period, and taking X2 as a blanking intensity threshold corresponding to the daytime time period; if Q2 is less than X2, taking Q2 as a light-off intensity threshold value corresponding to the daytime time period and taking X2 as a light-on intensity threshold value corresponding to the nighttime time period; when Q2 is X2, Q2 is defined as the turning-off intensity threshold value for the daytime period, and X2 is defined as the lighting intensity threshold value for the nighttime period. The first preset intensity X1 and the second preset intensity X2 are set by an operation and maintenance person or a user as needed, and the embodiment is not particularly limited.

Further, step S207 may include:

taking the difference between the first illumination intensity and a third preset intensity as a first extinction intensity threshold corresponding to the night time period, and taking the sum of the first illumination intensity and the third preset intensity as a first illumination intensity threshold corresponding to the night time period;

taking the difference between the second illumination intensity and a fourth preset intensity as a second extinction intensity threshold value corresponding to the daytime time period, and taking the sum of the first illumination intensity and the fourth preset intensity as a second lighting intensity threshold value corresponding to the daytime time period;

in the present embodiment, the value obtained by subtracting the third preset intensity X3 from the first illumination intensity Q1, i.e., Q1-X3, is used as the extinction intensity threshold corresponding to the night time period, and the value obtained by adding X3 to Q1, i.e., Q1+ X3, is used as the lighting intensity threshold corresponding to the night time period; the second illumination intensity Q2 minus the value of the fourth preset intensity X4, i.e., Q2-X4, is taken as the extinction intensity threshold corresponding to the daytime period, and the value of Q2 plus X4, i.e., Q2+ X4, is taken as the lighting intensity threshold corresponding to the daytime period. The third preset intensity X3 and the fourth preset intensity X4 are set by an operation and maintenance person or a user as needed, and the embodiment is not particularly limited.

The two methods of determining the extinguishing intensity threshold and the lighting intensity threshold corresponding to each time period according to the first illumination intensity and the second illumination intensity may alternatively be implemented.

In this embodiment, household electrical appliances set up the intensity threshold of lighting and extinguish the intensity threshold for each time quantum automatically according to user's historical sleep start time and historical sleep finish time, need not user's manual setting intensity threshold of lighting and extinguish the intensity threshold, have promoted light control's intelligence, make the intensity threshold of lighting and extinguish intensity threshold that sets up laminate with user's habit more moreover, have further promoted user experience.
