[0069] In some cases, the light source of existing refrigeration equipment is mainly a panel light source, but the light distribution is uneven, there are many shadow areas, and it is easy to cause eye irritation when the door is frequently opened and closed. In addition, the lighting effect of the internal surface light source of the refrigeration equipment is not natural enough and cannot present a natural lighting effect.

[0070] Based on the above, this application proposes a cooling device and its lighting control method, a cooling device and a storage medium, which aim to automatically adjust the lighting to achieve a natural lighting effect.

[0071] The various embodiments of the refrigeration equipment of this application will be further described below with reference to the accompanying drawings.

[0072] like Figure 1 As shown, Figure 1 This is a schematic diagram of the functional space provided in one embodiment of this application.

[0073] In one embodiment, a lighting device 110 is provided in the functional space 100 of the refrigeration equipment. The lighting device 110 includes a first color temperature light source, a second color temperature light source, and an optical diffuser plate 120. The first color temperature light source and the second color temperature light source are disposed inside the lighting device 110, and the optical diffuser plate 120 is disposed on the surface of the lighting device 110.

[0074] In one embodiment, an optical diffuser plate 120 is disposed on the surface of the lighting device 110 to diffuse and homogenize the light emitted by the first color temperature light source and the second color temperature light source. Through the optical diffuser plate 120, direct glare generated by the light source can be avoided, and the light can illuminate the functional space 100 of the cooling equipment more softly and evenly.

[0075] In one embodiment, the interior of the lighting device 110 is further provided with a reflector 130, and the first color temperature light source, the second color temperature light source and the optical diffuser 120 are all located on the same side of the reflector 130. The reflector 130 is used to reflect the light emitted by the first color temperature light source and the second color temperature light source to the optical diffuser 120.

[0076] In one embodiment, the reflector 130 is installed inside the lighting device 110, behind the first color temperature light source and the second color temperature light source, and efficiently reflects the light emitted by the light source to the optical diffuser 120, thereby improving the utilization rate of light and the lighting efficiency. The reflector 130 is made of a high reflectivity material (such as aluminum foil, white polyester film or mirror reflective coating).

[0077] In one embodiment, a black light-absorbing material layer 140 is provided on the inner side of the lighting device 110. The black light-absorbing material layer 140 may be a black flocked fabric.

[0078] It should be noted that the black light-absorbing material layer can absorb almost all incident light, including visible and infrared light, and has low reflectivity, thereby effectively reducing light reflection inside the device. By absorbing background light, the black light-absorbing material layer can significantly improve the contrast of light, making the lighting effect clearer and softer.

[0079] In one embodiment, the optical diffuser 120 includes one of the following: a light scattering plate and a light homogenizing plate.

[0080] In one embodiment, a heat dissipation structure 150 is also provided in the functional space.

[0081] In one embodiment, a lighting device is installed at the top of the functional space. A diffuser reflects the light downwards, and a Rayleigh diffuser is placed below the lighting device. After passing through the Rayleigh diffuser, the light simulates the effect of a blue sky. A dual-color array LED light source is installed at the top, with one high color temperature (8000K) and the other a low color temperature (3000K). By controlling the duty cycle of the two LEDs, different color temperature effects can be dynamically mixed. Upon detecting door opening via a door opening signal, the color temperature is dynamically adjusted from low to high within a preset time to simulate different natural light effects.

[0082] In one embodiment, a light sensor is installed outside the door of the refrigeration equipment to automatically adjust the light intensity and color temperature according to the ambient light intensity.

[0083] Based on the hardware structure of the above embodiments, various embodiments of the lighting control method for the cooling device of this application are presented below.

[0084] like Figure 2 As shown, Figure 2 This is a flowchart of a lighting control method for a refrigeration device provided in one embodiment of this application; the lighting control method for a refrigeration device in this embodiment includes, but is not limited to, steps S210, S220 and S230, which will be described in turn below.

[0085] Step S210: In response to the door opening signal of the functional space, determine the target light effect mode to be executed;

[0086] Step S220: Determine the duty cycle variation range and brightness variation range of the first color temperature light source and the second color temperature light source according to the target light effect mode, wherein the color temperature of the first color temperature light source is higher than the color temperature of the second color temperature light source.

[0087] Step S230: Within the target duration, control the first color temperature light source and the second color temperature light source based on the duty cycle change range and the brightness change range, so as to display the lighting gradient effect corresponding to the target light effect mode through the optical diffuser.

[0088] In one embodiment, when the door of the functional space is opened, the system receives a door opening signal. This signal triggers the system to enter a working state, and the system determines the target lighting effect mode to be executed according to preset rules or user settings. Based on the target lighting effect mode, the system determines the duty cycle variation range and brightness variation range of the first color temperature light source and the second color temperature light source. The color temperature of the first color temperature light source is higher than that of the second color temperature light source. Within the target duration, the system dynamically controls the first and second color temperature light sources according to the duty cycle variation range and brightness variation range determined in step S220. Through an optical diffuser, the light mixed from the two light sources is evenly diffused into the functional space, displaying a lighting gradient effect corresponding to the target lighting effect mode. This embodiment achieves the function of automatically adjusting the lighting effect based on the door opening signal by intelligently controlling the duty cycle and brightness of different color temperature light sources. This lighting gradient effect not only improves the user experience but also allows for flexible adjustment of the lighting mode according to different scenarios and user preferences.

[0089] In one embodiment, when the target duration is 5 seconds, within 5 seconds, the duty cycle of the first color temperature light source is set to change from 0% to 100%, and the brightness of the first color temperature light source is set to change from 20% to 85%. The duty cycle of the second color temperature light source is set to change from 100% to 0%, and the brightness of the second color temperature light source is set to change from 20% to 85%. The system gradually adjusts the first color temperature light source and the second color temperature light source according to the set duty cycle and brightness change range. The optical diffusion plate uniformly diffuses the light mixed from the two light sources into the functional space.

[0090] In one embodiment, when the target duration is 3 seconds, within 3 seconds, the duty cycle of the first color temperature light source is set to change from 50% to 60%, and the brightness of the first color temperature light source is set to change from 20% to 95%. The duty cycle of the second color temperature light source is set to change from 50% to 40%, and the brightness of the second color temperature light source is set to change from 20% to 95%. The system gradually adjusts the first color temperature light source and the second color temperature light source according to the set duty cycle and brightness change range. The optical diffusion plate uniformly diffuses the light mixed from the two light sources into the functional space.

[0091] In one embodiment, when the target duration is 3 seconds, within 3 seconds, the duty cycle of the first color temperature light source is set to change from 30% to 40%, and the brightness of the first color temperature light source is set to change from 20% to 40%. The duty cycle of the second color temperature light source is set to change from 70% to 60%, and the brightness of the second color temperature light source is set to change from 20% to 40%. The system gradually adjusts the first color temperature light source and the second color temperature light source according to the set duty cycle and brightness change range. The optical diffusion plate uniformly diffuses the light mixed from the two light sources into the functional space.

[0092] In addition, it is understood that the type of door switch sensor for the functional space can be a mechanical switch, a reed switch, a capacitive sensor, an inductive sensor, an ultrasonic sensor, or other types of door switch sensors for the functional space. The embodiments of this application do not limit the specific type of door switch sensor for the functional space.

[0093] like Figure 3 As shown, Figure 3 This is a flowchart of determining the target light effect mode to be executed based on the current ambient brightness according to one embodiment of this application; the cooling device is equipped with a light sensor for detecting the ambient brightness. Regarding the determination of the target light effect mode to be executed in the above step S210, it includes, but is not limited to, steps S310 and S320. The steps are described in turn below.

[0094] Step S310: Detect the current ambient brightness of the surrounding environment of the cooling equipment using a light sensor;

[0095] Step S320: Determine the target lighting effect mode to be executed based on the current ambient brightness.

[0096] In one embodiment, during operation, the system uses a light sensor to detect the current brightness of the environment around the cooling device in real time. The light sensor can sense the intensity of ambient light and convert it into an electrical signal. Based on the current ambient brightness detected by the light sensor, the system selects the most suitable light effect mode from a preset light effect mode library. Different ambient brightness corresponds to different light effect modes to ensure that the lighting effect meets the user's needs while avoiding energy waste caused by excessive lighting.

[0097] In one embodiment, the system determines that the current environment is dark, possibly at night or with insufficient indoor light. In this case, the system selects "night mode" as the target lighting mode. In this mode, the brightness of the lighting inside the refrigerator will be reduced appropriately, and the color temperature will be adjusted to warm white light to create a soft visual effect while reducing energy consumption.

[0098] In one embodiment, the system determines that the current environment is relatively bright, possibly during the day or in a well-lit indoor environment. In this case, the system selects "daytime mode" as the target lighting mode. In this mode, the brightness of the lighting inside the refrigerator is appropriately increased, and the color temperature is adjusted to cool white light to provide a clear and bright visual effect while avoiding excessive contrast with the external ambient light.

[0099] In addition, it is understood that the type of light sensor can be a photoresistor, a photodiode, a phototransistor, or other types of light sensors. This application does not limit the specific type of light sensor.

[0100] In one embodiment, determining the target lighting effect mode to be executed based on the current ambient brightness includes one of the following:

[0101] When the current ambient brightness is greater than the first preset brightness and less than the second preset brightness, the target light effect mode to be executed is determined to be the first light effect mode used to simulate the morning sunrise light effect.

[0102] When the current ambient brightness is greater than or equal to the second preset brightness, the target light effect mode to be executed is determined to be the second light effect mode used to simulate the daytime gradually brightening light effect.

[0103] When the current ambient brightness is less than or equal to the first preset brightness, the target lighting effect mode to be executed is determined to be the third lighting effect mode used to simulate nighttime lighting effects.

[0104] It should be noted that the first preset brightness is used to distinguish between the first light effect mode and the third light effect mode, and the second preset brightness is used to distinguish between the first light effect mode and the second light effect mode.

[0105] In one embodiment, if the current ambient brightness is greater than a first preset brightness and less than a second preset brightness, the target light effect mode to be executed is determined to be the first light effect mode. The first light effect mode simulates the light effect of sunrise in the morning, gradually changing from dark to bright. Based on the duty cycle change range and the brightness change range, the color temperature of the first color temperature light source and the second color temperature light source is controlled to transition from warm color to natural white light. The first light effect mode is suitable for use in the early morning or low light environment, helping users gradually adapt to the bright environment.

[0106] In one embodiment, if the current ambient brightness is greater than or equal to a second preset brightness, the target light effect mode to be executed is determined to be the second light effect mode. The second light effect mode simulates the light effect of daytime, and controls the first color temperature light source and the second color temperature light source based on the duty cycle change range and the brightness change range to provide high brightness and natural white light. It is suitable for use in bright environments. The second light effect mode can provide clear and bright lighting effects while avoiding excessive contrast with the external ambient light.

[0107] In one embodiment, if the current ambient brightness is less than or equal to a first preset brightness, the target light effect mode to be executed is determined to be the third light effect mode. The third light effect mode simulates a nighttime environment and controls the first color temperature light source and the second color temperature light source based on the duty cycle change range and the brightness change range to provide low brightness and warm light, which is suitable for use in the dark or at night. The third light effect mode can create a warm and comfortable atmosphere while protecting the eyes from strong light stimulation.

[0108] like Figure 4 As shown, Figure 4 This is a flowchart of determining the target light effect mode to be executed based on the current time according to an embodiment of this application; regarding the determination of the target light effect mode to be executed in the above step S210, including but not limited to steps S410 and S420, each step will be described in turn below.

[0109] Step S410: Obtain the current time;

[0110] Step S420: Determine the target lighting effect mode to be executed based on the current time.

[0111] In one embodiment, the system obtains the current date and time information via a built-in clock module or by synchronizing with an external time server. The time information typically includes hours, minutes, and seconds. A built-in RTC (Real-Time Clock) module provides accurate time information, while NTP (Network Time Protocol) can be used to obtain time from an external server, ensuring accuracy and synchronization. Based on the current time, the system selects the corresponding target lighting effect mode from a preset time-to-lighting-effect-mode mapping table. Different time periods can correspond to different lighting effect modes to simulate changes in natural light or meet the needs of specific scenarios.

[0112] like Figure 5 As shown, Figure 5 yes Figure 4 The flowchart below shows a sub-step of an embodiment of step S420. Regarding the determination of the target light effect mode to be executed based on the current time in step S420, including but not limited to steps S510 and S520, each step will be described in turn below.

[0113] Step S510: Compare the current time with at least one preset time period;

[0114] Step S520: When the current time is within the target time period, determine the target light effect mode to be executed according to the target time period, wherein the target time period is one of at least one preset time period.

[0115] In one embodiment, the system acquires the current time and compares it with a set of preset time periods to determine which time period the current time belongs to. The preset time periods are divided according to different stages of the day, and each time period corresponds to a specific lighting effect mode. The system internally stores multiple preset time periods, each defined by a start time and an end time. For example: first preset time period: 7:00-10:00 (morning), second preset time period: 10:00-18:00 (daytime), third preset time period: 18:00-7:00 (night). The system compares the current time with each preset time period one by one to determine if the current time falls within a certain time period. When the current time falls within a preset time period (target time period), the system selects the corresponding target lighting effect mode according to the definition of that time period. Each time period corresponds to a specific lighting effect mode to simulate changes in natural light or meet the needs of a specific scene.

[0116] In one embodiment, when the current time is within a target time period, the target lighting effect mode to be executed is determined based on the target time period, including one of the following:

[0117] When the current time is within the first preset time period, the target light effect mode to be executed is determined to be the first light effect mode used to simulate the morning sunrise light effect;

[0118] When the current time is within the second preset time period, the target light effect mode to be executed is determined to be the second light effect mode used to simulate the daytime gradual brightening light effect, wherein the second preset time period is later than the first preset time period;

[0119] When the current time is within the third preset time period, the target lighting effect mode to be executed is determined to be the third lighting effect mode used to simulate nighttime lighting effects, wherein the third preset time period is later than the second preset time period.

[0120] In one embodiment, the first preset time period is from 7:00 to 10:00. The target light effect mode to be executed is determined to be the first light effect mode. The first light effect mode simulates the light effect of sunrise in the morning, gradually changing from dark to bright. Based on the duty cycle change range and the brightness change range, the color temperature of the first color temperature light source and the second color temperature light source is controlled to transition from warm color to natural white light. The first light effect mode is suitable for use in the early morning or low light environment, helping users to gradually adapt to the bright environment.

[0121] In one embodiment, the second preset time period is from 10:00 to 18:00. The target light effect mode to be executed is determined to be the second light effect mode. The second light effect mode simulates the light effect of daytime. Based on the duty cycle change range and the brightness change range, the first color temperature light source and the second color temperature light source are controlled to provide high brightness and natural white light. It is suitable for use in bright environments. The second light effect mode can provide clear and bright lighting effects while avoiding excessive contrast with the external ambient light.

[0122] In one embodiment, the third preset time period is from 18:00 to 7:00. The target light effect mode to be executed is determined to be the third light effect mode. The third light effect mode simulates the nighttime environment and controls the first color temperature light source and the second color temperature light source based on the duty cycle change range and the brightness change range to provide low brightness and warm light. It is suitable for use in the dark or at night. The third light effect mode can create a warm and comfortable atmosphere while protecting the eyes from strong light stimulation.

[0123] like Figure 6 As shown, Figure 6 yes Figure 4 The flowchart of another embodiment of step S420 shown is a sub-step flowchart; regarding the determination of the corresponding target light effect mode to be executed according to the current time in step S420, including but not limited to steps S610, S620 and S630, each step will be described in turn below.

[0124] Step S610: Obtain the current geographical location of the refrigeration equipment;

[0125] Step S620: Determine the day and night time elements corresponding to the current geographical location, wherein the day and night time elements include one of the following: sunrise time, sunset time, noon time, and night time;

[0126] Step S630: Determine the target lighting effect mode to be executed based on the current time and day / night time elements.

[0127] In one embodiment, the system obtains the current location information of the cooling device via a built-in GPS module or through a network. The geographic location information typically includes longitude and latitude. Alternatively, the cooling device can be connected to a smart home system, and the location information can be obtained via the home network's IP address or an address manually entered by the user. Based on the obtained geographic location information, the system calculates or queries the day / night time elements corresponding to the current date, including sunrise time, sunset time, noon time, and nighttime. These time elements vary depending on geographic location and season, and are dynamically calculated or queried.

[0128] It should be noted that the system compares the current time with the day and night time elements and selects an appropriate lighting mode based on the current time period. Different lighting modes can simulate changes in natural light, such as the soft light at sunrise, the bright light during the day, the warm light in the evening, and the low-brightness light at night.

[0129] In one embodiment, the target lighting effect mode to be executed is determined based on the current time and day / night time elements, including one of the following:

[0130] When the current time is sunrise or sunset, the target lighting effect mode to be executed is determined to be the first lighting effect mode used to simulate the morning sunrise lighting effect;

[0131] When the current time is noon, the target lighting effect mode to be executed is determined to be the second lighting effect mode used to simulate the gradual brightening effect during the day;

[0132] When the current time is nighttime, the target lighting effect mode to be executed is determined to be the third lighting effect mode used to simulate nighttime lighting effects.

[0133] In one embodiment, the system first detects a door opening signal and obtains the current geographical location, sunrise time, sunset time, and current time via an IoT connection. After obtaining the current time, the system compares the current time with day / night time elements to determine whether the current time falls within a certain day / night time element. When the current time falls within a certain day / night time element, the system selects the corresponding target lighting effect mode according to the definition of that time period. Each time period corresponds to a specific lighting effect mode to simulate changes in natural light or meet the needs of a specific scenario.

[0134] In one embodiment, determining the duty cycle variation range and brightness variation range of the first color temperature light source and the second color temperature light source based on the target light effect mode includes:

[0135] Based on the target light effect mode, determine the first duty cycle variation range of the first color temperature light source that increases and the second duty cycle variation range of the second color temperature light source that decreases. The sum of the maximum value of the first duty cycle variation range and the minimum value of the second duty cycle variation range is one, and the sum of the minimum value of the first duty cycle variation range and the maximum value of the second duty cycle variation range is one.

[0136] The incremental brightness variation range of the first color temperature light source and the second color temperature light source is determined based on the target light effect mode.

[0137] It should be noted that the sum of the maximum value of the first duty cycle change interval and the minimum value of the second duty cycle change interval is one, and the sum of the minimum value of the first duty cycle change interval and the maximum value of the second duty cycle change interval is one. This ensures that the sum of the duty cycles of the two light sources is 1 at any time, thereby achieving a smooth transition of light effect and avoiding abrupt changes in light effect.

[0138] In one embodiment, the first duty cycle range is 0% to 100%, the second duty cycle range is 0% to 100%, and at any given time, the sum of the first duty cycle and the second duty cycle is 100%.

[0139] In one embodiment, initially the duty cycle of the first color temperature light source is 0% and the brightness is 20%; the duty cycle of the second color temperature light source is 100% and the brightness is 20%. As time changes, the duty cycle of the first color temperature light source gradually increases to 60% and the brightness increases to 85%; the duty cycle of the second color temperature light source gradually decreases to 40% and the brightness increases to 85%.

[0140] In one embodiment, initially, the duty cycle of the first color temperature light source is 50% and the brightness is 20%; the duty cycle of the second color temperature light source is 50% and the brightness is 20%. As time changes, the duty cycle of the first color temperature light source gradually increases to 60% and the brightness increases to 95%; the duty cycle of the second color temperature light source gradually decreases to 40% and the brightness increases to 95%.

[0141] In one embodiment, initially the duty cycle of the first color temperature light source is 30% and the brightness is 20%; the duty cycle of the second color temperature light source is 70% and the brightness is 20%. As time changes, the duty cycle of the first color temperature light source gradually increases to 40% and the brightness increases to 40%; the duty cycle of the second color temperature light source gradually decreases to 60% and the brightness increases to 40%.

[0142] In one embodiment, when the target light effect mode is a first light effect mode for simulating the light effect of a morning sunrise, the first duty cycle variation range is a first numerical range;

[0143] When the target lighting effect mode is the second lighting effect mode used to simulate the gradual brightening effect during the day, the first duty cycle change range is the second numerical range, wherein the second numerical range is located within the first numerical range;

[0144] When the target lighting effect mode is the third lighting effect mode used to simulate nighttime lighting effects, the first duty cycle change range is the third numerical range, wherein the third numerical range is located between the minimum value of the first numerical range and the minimum value of the second numerical range.

[0145] In one embodiment, when the target light effect mode is a first light effect mode for simulating morning sunrise light effect, the first value range is 0% to 100%; when the target light effect mode is a second light effect mode for simulating daytime gradually brightening light effect, the second value range is 50% to 60%; and when the target light effect mode is a third light effect mode for simulating nighttime light effect, the third value range is 0% to 50%.

[0146] In one embodiment, when the target light effect mode is a first light effect mode for simulating the light effect of a morning sunrise, the brightness variation range is a first brightness range;

[0147] When the target lighting effect mode is the second lighting effect mode used to simulate the gradual brightening effect during the day, the brightness change range is the second brightness range, where the maximum value of the second brightness range is greater than the maximum value of the first brightness range.

[0148] When the target lighting effect mode is the third lighting effect mode used to simulate nighttime lighting effects, the brightness variation range is the third brightness range, where the maximum value of the third brightness range is less than the maximum value of the first brightness range.

[0149] In one embodiment, when the target light effect mode is a first light effect mode for simulating the light effect of sunrise in the morning, the first brightness range is 20% to 85%; when the target light effect mode is a second light effect mode for simulating the light effect of daytime gradual brightening, the second brightness range is 20% to 95%; and when the target light effect mode is a third light effect mode for simulating the light effect of nighttime, the third brightness range is 20% to 40%.

[0150] It should be noted that this application does not impose specific limitations on the minimum value of the brightness variation range, and it can be adjusted according to the actual lighting effect.

[0151] In one embodiment, the target duration is determined by the following steps: determining the corresponding target duration based on the target light effect mode.

[0152] In one embodiment, the target duration of the first light effect mode is 5 seconds, the target duration of the second light effect mode is 3 seconds, and the target duration of the third light effect mode is 3 seconds. The target duration can be adjusted according to the specific actual situation.

[0153] In one embodiment, the target duration is determined based on the target light effect pattern, including one of the following:

[0154] When the target lighting effect mode is the first lighting effect mode used to simulate the morning sunrise lighting effect, the target duration is determined to be the first duration.

[0155] When the target lighting effect mode is a second lighting effect mode used to simulate daytime lighting effects or a third lighting effect mode used to simulate nighttime lighting effects, the target duration is determined to be the second duration, wherein the first duration is longer than the second duration.

[0156] In one embodiment, when the target light effect mode is a first light effect mode for simulating morning sunrise light effect and the target duration of the first light effect mode is 5 seconds, the duty cycle range of the first color temperature light source is controlled to increase from 0% to 100% within 5 seconds, and the brightness of the first color temperature light source is controlled to increase from 20% to 85% within 5 seconds; when the target light effect mode is a second light effect mode for simulating daytime gradual brightening light effect and the target duration of the second light effect mode is 3 seconds, the duty cycle range of the first color temperature light source is controlled to increase from 50% to 60% within 3 seconds, and the brightness of the first color temperature light source is controlled to increase from 20% to 95% within 3 seconds; when the target light effect mode is a third light effect mode for simulating nighttime light effect and the target duration of the third light effect mode is 3 seconds, the duty cycle range of the first color temperature light source is controlled to increase from 30% to 40% within 3 seconds, and the brightness of the first color temperature light source is controlled to increase from 20% to 40% within 3 seconds.

[0157] like Figure 7 As shown, Figure 7 This is a duty cycle control logic diagram provided in one embodiment of this application.

[0158] In one embodiment, a high color temperature LED is used as the first color temperature light source. The duty cycle of the high color temperature LED is a rectangular wave, the width of which is determined by S1 / f. The waveform of the high color temperature LED is also a square wave, the duty cycle of which is determined by S1. A low color temperature LED is used as the second color temperature light source. The duty cycle of the low color temperature LED is a rectangular wave, the width of which is determined by S2 / f. The waveform of the low color temperature LED is also a square wave, the duty cycle of which is determined by S2. S1 is the duty cycle parameter of the first color temperature, and S2 is the duty cycle parameter of the second color temperature, used to adjust the color temperature. Their sum is 100%. When S1 is larger, the duty cycle of the high color temperature is higher, and vice versa. W1 and W2 are brightness parameters, obtained by multiplying S1 and S2 by L and then dividing by F, respectively. L is the brightness adjustment parameter, ranging from 0% to 100%, and F is the PWM frequency.
