[0090] To make the objectives, implementation manners and advantages of the present application clearer, the following will clearly and completely describe the exemplary implementation manners of the present application with reference to the accompanying drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0091] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the subsequent described implementation manners, rather than intending to limit the implementation manners of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0092] In addition, the terms "comprising", "having" and any variations thereof are intended to cover inclusion without exclusivity. For example, a product or device comprising a series of components need not be limited to those components clearly listed, but may include other components not clearly listed or inherent to those products or devices.

[0093] Currently, most refrigerators use UVC for sterilization, which has the advantages of weak penetration and high sterilization efficiency. However, it is easy to damage transparent plastic materials, such as material discoloration, powdering, precipitation, etc., affecting the user experience and physical health.

[0094] Therefore, it is very necessary to conduct UVC resistance tests on materials applied to refrigerators and within the UVC irradiation range. When conducting aging tests on materials applied to household appliances and within the UVC irradiation range in a UVC sterilization environment, how to simulate the UVC sterilization environment to achieve the aging effect of the applied materials in this UVC sterilization environment, so as to determine whether the materials are suitable for the UVC sterilization environment, is an urgent problem to be solved.

[0095] In the related art, the sterilization environment can be simulated by setting the UVC irradiation intensity. However, the main indicators affecting the UVC resistance performance of materials are UVC irradiation intensity, irradiation distance, irradiation duration, etc. For materials applied to refrigerators and within the irradiation range, due to different positions, the distance from the light source component is different, so the actual use environment of the materials in the refrigerator cannot be accurately simulated, and the aging effect of the materials in the UVC sterilization environment of the refrigerator cannot be achieved.

[0096] Therefore, the present application provides a lighting device, which can simulate the UVC sterilization environment of a sample to be tested in an actual household appliance in use by setting the irradiation intensity, irradiation distance and irradiation duration, so as to achieve the aging effect of the sample to be tested in the UVC sterilization environment of the actual household appliance in use.

[0097] The technical solutions of the present application will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other or exist independently. For the same or similar concepts or processes, they may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0098] Reference Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of a lighting device provided by an embodiment of the present application. Figure 2 is an internal structural diagram of the lighting device provided by an embodiment of the present application. The lighting device 10 includes a box body 100, and the box body 100 has a receiving cavity. The box body 100 is used to implement a closed experiment, so as to effectively prevent UVC leakage and cause damage to the human body.

[0099] The test bench 101, the light source assembly 102, the rotation drive assembly 103, and the control assembly (not shown in the figure) can be arranged in the accommodation cavity.

[0100] Among them, the test bench 101 is configured to place the sample to be tested. Exemplarily, the sample to be tested can be a material applied in a UVC sterilization environment in a refrigerator, such as a polymer material.

[0101] The light source assembly 102 is configured to emit UVC to the test bench 101. Exemplarily, the light source assembly 102 can be arranged inside the top of the lighting device 10 so that the UVC it irradiates can evenly irradiate the test bench 101.

[0102] The rotation drive assembly 103 is configured to control the test bench 101 to move away from or close to the light source assembly 102.

[0103] The control assembly is configured to:

[0104] Obtain the target irradiation intensity, the target irradiation distance, and the target irradiation duration. Through the rotation drive assembly 103, control the distance between the test bench 101 and the light source assembly 102 to be the target irradiation distance. Turn on the light source assembly 102 and control the light source assembly 102 to emit UVC at the target irradiation intensity. After the light source assembly 102 works for the target irradiation duration at the target irradiation intensity, turn off the light source assembly 102.

[0105] Among them, the target irradiation intensity refers to the radiation intensity of the light source assembly 102 on the sample to be tested. The target irradiation distance can be set as the distance between the light source assembly 102 and the test bench 101, or, since the sample to be tested can have any shape and a certain height, the target irradiation distance can also be set as the distance between the light source assembly 102 and the sample to be tested. The tester can set it according to specific requirements. For example, it can be determined according to the position of the sample to be tested within the UVC radiation range of the refrigerator. This application does not make any limitations.

[0106] In this embodiment, the lighting device 10 includes a test bench 101, a light source assembly 102, a rotation drive assembly 103, and a control assembly. Among them, the test bench 101 is configured to place the sample to be tested, the light source assembly 102 is configured to emit UVC to the test bench 101, and the rotation drive assembly 103 is configured to control the test bench 101 to move away from or close to the light source assembly 102. The control assembly is configured to obtain the target irradiation intensity, target irradiation distance, and target irradiation duration, and through the rotation drive assembly 103, control the distance between the test bench 101 and the light source assembly 102 to be the target irradiation distance, turn on the light source assembly 102, and control the light source assembly 102 to emit UVC at the target irradiation intensity. After the light source assembly 102 operates at the target irradiation intensity for the target irradiation duration, turn off the light source assembly 102. The lighting device provided in the embodiment of the present application can accurately and efficiently simulate the usage environment of the sample to be tested in an actual household appliance, so that the aging effect of the sample to be tested in the UVC sterilization environment is close to the aging effect during its actual use in the household appliance.

[0107] In a possible implementation, as Figure 1 and Figure 2 shown, the lighting device 10 further includes a display panel 104. The tester can select the target test mode through the display panel 104, so as to input test parameters, for example, irradiation distance, irradiation intensity, irradiation time, etc.

[0108] In a possible implementation, the lighting device 10 further includes a camera assembly (not shown in the figure). The camera assembly is connected to the control assembly and is configured to photograph the sample to be tested. The camera assembly can record and transmit the change process of the sample to be tested in real time, so as to facilitate the tester to view.

[0109] In a possible implementation, Figure 3 is a schematic structural diagram of a rotation drive assembly 103 provided in an embodiment of the present application. As Figure 3 shown, the rotation drive assembly 103 may include a lifting assembly 31 and a driving motor 32. The lifting assembly 31 is respectively connected to the driving motor 32 and the test bench 101. The driving motor 32 can drive the test bench 101 to rise or fall through the lifting assembly 31, so as to control the test bench 101 to move away from or close to the light source assembly 102.

[0110] In a possible implementation, as Figure 1 shown, the lighting device 10 further includes a door body 105. The box body 100 has an opening on it. The box body 100 is connected to the door body 105. The door body 105 is configured to open or close the opening. The box body 100 is configured to block the UVC emitted by the light source assembly 102 outside the lighting device 10.

[0111] The tester can open the door body 105, place the sample to be tested into the test bench 101 through this opening, and then by closing the door body 105, the radiation of the light source assembly 102 can be isolated through the door body 105 and the housing 104, so that the UVC radiated by the light source assembly 102 will not cause harm to the tester.

[0112] In a possible implementation, the light source assembly 102 may further include a plurality of UVC-LEDs, that is, UVC light-emitting diodes (Light Emitting Diode, LED). The control component can control whether the UCV light source 102 emits UVC by turning on or off the plurality of UVC-LEDs.

[0113] Based on the above lighting device 10, the control method of the lighting device provided in the embodiments of the present application will be described below.

[0114] Figure 4 It is a schematic flowchart of a control method for a lighting device provided in an embodiment of the present application. This method can be executed by the control component of the above lighting device 10, as Figure 4 shown, this method may include the following steps.

[0115] S401. Obtain the target irradiation intensity, target irradiation distance, and target irradiation duration.

[0116] S402. Control the distance between the test bench and the light source assembly to be the target irradiation distance by rotating the drive component.

[0117] In a possible implementation, the control component can control the distance between the test bench and the light source assembly to be the target irradiation distance through the distance sensor provided in the lighting device 10.

[0118] In another possible implementation, after obtaining the target irradiation distance, the control component can determine the preset position where the test bench stays according to the target irradiation distance, and the control component can control the test bench to reach the preset position through the displacement sensor provided in the lighting device.

[0119] S403. Turn on the light source assembly and control the light source assembly to emit UVC at the target irradiation intensity.

[0120] In a possible implementation, the control component can control the light source assembly to emit UVC at the target irradiation intensity in the following manner:

[0121] The control component can determine the preset number of UVC-LEDs to be turned on, the target voltage, and the target current of the preset number of UVC-LEDs according to the target irradiation intensity. That is to say, the control component can control the intensity of the light source component to radiate to the target irradiation intensity according to the number of UVC-LEDs turned on, as well as the target voltage and target current of the UVC-LEDs.

[0122] Exemplarily, the target irradiation intensity can be determined according to the following formula:

[0123]

[0124] Where ρ is the target irradiation intensity, S is the area of the test bench, P is the power of the UVC-LED, P = U×I×n×k, where U is the target voltage of the UVC-LED, I is the target current of the UVD-LED, n is the preset number, and k is the power correction factor.

[0125] S404. After the light source component works for the target irradiation duration at the target irradiation intensity, turn off the light source component.

[0126] In this embodiment, the target irradiation intensity, the target irradiation distance, and the target irradiation duration are obtained. By rotating the driving component, the distance between the test bench and the light source component is controlled to be the target irradiation distance, the light source component is turned on, and the light source component is controlled to emit UVC at the target irradiation intensity. After the light source component works for the target irradiation duration at the target irradiation intensity, the light source component is turned off. It can accurately and efficiently simulate the usage environment of the sample to be tested in the actual household appliances, so that the aging effect of the sample to be tested in the UVC sterilization environment is close to the aging effect of its actual use in household appliances.

[0127] Figure 5 It is a schematic flowchart of another control method for the lighting device provided by the embodiment of the present application. This method can be executed by the control component 104 of the lighting device 10 as described above. As Figure 5 shown, this method can include the following steps.

[0128] S501. Determine the target test mode, and the target test mode is the actual application mode, the accelerated aging mode, or the custom mode.

[0129] In a possible implementation manner, the lighting device can have multiple test modes, including the actual application mode, the accelerated aging mode, or the custom mode.

[0130] Among them, the actual application mode means that in this mode, the user can simulate the actual environment of the sample to be tested in the refrigerator according to the radiation environment it receives during actual application in the refrigerator. It can be understood that in this model, the target radiation intensity can be the intensity required for refrigerator sterilization, the target irradiation distance can be the distance between the position where the sample to be tested is set in the refrigerator and the light source component, and the target irradiation duration can be the duration corresponding to a sterilization cycle of the refrigerator, or it can also be the service life of the sample to be tested in the refrigerator.

[0131] The accelerated aging mode means that in this mode, the accelerated aging test can be carried out. For example, the tester can reduce the test time by increasing the irradiation intensity to achieve the purpose of acceleration.

[0132] The custom mode means that the tester can set multiple groups of test parameters so that the lighting device can test multiple groups of test parameters. In a possible implementation, the custom mode can be a combined mode of the actual application mode and the accelerated aging mode. Exemplarily, the multiple groups of test parameters can include the test parameters corresponding to the actual application mode and the test parameters corresponding to the accelerated aging mode, so that the lighting device can first simulate the radiation environment received by the sample to be tested during actual application in the refrigerator, and then simulate the aging process of the sample to be tested in the refrigerator. For example, the accelerated aging mode can be used to simulate the aging state of the sample to be tested under the UVC sterilization environment of long-term application in the refrigerator, so as to obtain the aging effect close to that of the sample to be tested after long-term (such as 10 years or 20 years) of radiation under the UVC sterilization environment of the refrigerator in the custom mode.

[0133] In a possible implementation, various test modes can be displayed on the display panel of the lighting device, and the tester can select the target test mode to be tested from the various test modes.

[0134] S502. According to the target test mode, obtain the target irradiation intensity, the target irradiation distance, and the target irradiation duration.

[0135] After determining the target test mode, the control component can obtain the target irradiation intensity, the target irradiation distance, and the target irradiation duration according to the target test mode.

[0136] In a possible implementation, the lighting device may store test parameters corresponding to multiple test modes, namely, irradiation intensity, irradiation distance, and irradiation duration. Among them, the test parameters corresponding to each test mode can be determined by the tester according to factors such as the type of the sample to be tested and its application position in the refrigerator, and then prestored in the lighting device for subsequent testing to improve the test efficiency. Alternatively, the test parameters corresponding to the actual application mode can be determined by the tester according to factors such as the type of the sample to be tested and its application position in the refrigerator, and then the control component determines the test parameters corresponding to the accelerated aging mode according to the test parameters corresponding to the actual application mode, so as to determine the test parameters corresponding to the custom mode.

[0137] Exemplarily, the test parameters corresponding to the actual application mode are irradiation distance l0, irradiation intensity ρ0, and irradiation duration t0. The tester can determine the irradiation intensity ρ1 and irradiation distance l1 of the accelerated aging mode, and then the control component can determine the irradiation duration t1 according to the following formula:

[0138]

[0139] Alternatively, the tester can determine the irradiation duration t1 and irradiation distance l1 of the accelerated aging mode, and then the control component can determine the irradiation intensity ρ1 according to the above formula (2). Among them, is a correction parameter, which can be determined based on the time-temperature equivalence principle and combined with multiple test data.

[0140] In another possible implementation, the control component can obtain the target irradiation intensity, target irradiation distance, and target irradiation duration corresponding to the target test mode input by the tester through the display panel.

[0141] S503. By rotating the driving component, control the distance between the test bench and the light source component to be the target irradiation distance.

[0142] S504. Turn on the light source component and control the light source component to emit UVC at the target irradiation intensity.

[0143] S505. After the light source component works at the target irradiation intensity for the target irradiation duration, turn off the light source component.

[0144] For the specific implementation of the above steps, reference can be made to the above embodiments and will not be elaborated here.

[0145] In this embodiment, the control component can determine the target test mode, and then obtain the target irradiation intensity, target irradiation distance, and target irradiation duration according to the target test mode. By rotating the driving component, the distance between the test bench and the light source component is controlled to be the target irradiation distance, the light source component is turned on, and the light source component is controlled to emit UVC at the target irradiation intensity. After the light source component works at the target irradiation intensity for the target irradiation duration, the light source component is turned off. It can accurately and efficiently simulate the radiation environment of the sample to be tested in different test modes, so that the aging effect of the sample to be tested in the UVC sterilization environment is close to its actual aging effect when used in household appliances.

[0146] Next, an explanation will be given of how the control component obtains the target irradiation intensity, target irradiation distance, and target irradiation duration corresponding to the target test mode input by the tester through the display panel.

[0147] Figure 6 As shown in the flowchart of another control method for the lighting device provided by the embodiment of the present application, this method can be executed by the control component 104 of the lighting device 10 as described above. Figure 6 As shown, this method may include the following steps.

[0148] S601. Display a parameter input interface corresponding to the target test mode through the display panel.

[0149] After the lighting device is powered on, the display panel of the lighting device can display a parameter input interface corresponding to the target test mode.

[0150] Exemplarily, if the target test mode is the actual application mode, Figure 7 As shown in the schematic diagram of a parameter input interface exemplified by the embodiment of the present application, Figure 7 as shown, the parameter input interface corresponding to the actual application mode may include input boxes for irradiation intensity, irradiation distance, and irradiation duration.

[0151] Exemplarily, if the target test mode is the accelerated aging mode, Figure 8 As shown in the schematic diagram of another parameter input interface exemplified by the embodiment of the present application, Figure 8 as shown, the parameter input interface corresponding to the accelerated aging mode may include input boxes for irradiation intensity, irradiation distance, and irradiation duration corresponding to the actual application mode, as well as input boxes for irradiation intensity, irradiation distance, and irradiation duration corresponding to the accelerated aging mode.

[0152] Exemplarily, if the target test mode is the custom mode, Figure 9 As shown in the schematic diagram of yet another parameter input interface exemplified by the embodiment of the present application, Figure 9As shown, the parameter input interface corresponding to the custom mode may include input boxes for multiple groups of parameters. Among them, each group of parameter input boxes includes an input box for irradiation intensity, an input box for irradiation distance, and an input box for irradiation duration.

[0153] S602. Obtain the test parameters input by the user in the parameter input interface.

[0154] After the user selects the target test mode on the display panel, the user can input the corresponding test parameters in the parameter input interface corresponding to the target test mode.

[0155] S603. Determine the target irradiation intensity, target irradiation distance, and target irradiation duration according to the test parameters.

[0156] In a possible implementation manner, if the target test mode is the accelerated aging mode, the test parameters include the first irradiation intensity, the first irradiation distance, and the first irradiation duration.

[0157] The control component can obtain the calibration parameter, the target irradiation distance, and the first parameter. The first parameter is the target irradiation intensity or the target irradiation duration. According to the calibration parameter, the first irradiation intensity, the first irradiation distance, the first irradiation duration, the target irradiation duration, and the first parameter, determine the second parameter.

[0158] Among them, if the first parameter is the target irradiation intensity, the second parameter is the target irradiation duration; if the first parameter is the target irradiation duration, the second parameter is the target irradiation intensity. The first irradiation intensity, the first irradiation distance, and the first irradiation duration are the test parameters corresponding to the actual application mode.

[0159] Specifically, the control component can determine the second parameter according to the above formula (2).

[0160] In a possible implementation manner, if the target test mode is the actual application mode, the test parameters include the first irradiation intensity, the first irradiation distance, and the first irradiation duration;

[0161] The control component can determine the first irradiation intensity as the target irradiation intensity, the first irradiation distance as the target irradiation distance, and the first irradiation duration as the target irradiation duration.

[0162] In a possible implementation manner, the target test mode is the custom mode, and the test parameters include multiple groups of parameters and the identifier corresponding to each group of parameters. It can be understood that each group of parameters includes an irradiation intensity, an irradiation distance, and an irradiation duration.

[0163] Exemplarily, the test parameters corresponding to the custom mode can refer to Table 1.

[0164] Table 1

[0165]

[0166]

[0167] The control component can sequentially determine the target identifier from multiple identifiers, determine a set of parameters corresponding to the target identifier as the target set of parameters, and then determine the target irradiation intensity, target irradiation distance, and target irradiation duration according to the target set of parameters. For example, the target identifier is 2, the group corresponding to identifier 2 is the target set of parameters, the target irradiation intensity is ρ2, the target irradiation distance is L2, and the target irradiation duration is T2.

[0168] That is to say, in the custom mode, the control component needs to test each set of parameters in the test parameters.

[0169] In this embodiment, the user can select the target test mode through the display panel, and then input the corresponding irradiation intensity, irradiation distance, and irradiation duration based on this mode, so as to simulate the USV sterilization environment according to the parameters input by the user, which is convenient for the operation of the test personnel.

[0170] Figure 10 It is a schematic flowchart of another control method for the lighting device provided by the embodiment of the present application. This method can be executed by the control component 104 of the lighting device 10 as described above, as Figure 10 shown, and this method can include the following steps.

[0171] S1001. Control the distance between the test bench and the light source component to the target irradiation distance by rotating the driving component.

[0172] S1002. When the distance between the test bench and the light source component is the target irradiation distance, determine whether the test bench is in a horizontal position.

[0173] If yes, execute S1003; if no, execute S1004.

[0174] In a possible implementation manner, the control component can determine whether the test bench is in a horizontal position through a displacement sensor provided in the lighting device.

[0175] S1003. Turn on the light source component.

[0176] S1004. Output a first prompt message, which is used to prompt the user to adjust the test bench so that the test bench is in a horizontal position.

[0177] In this embodiment, when the distance between the control test bench and the light source assembly is the target irradiation distance, it is necessary to set the test bench in a horizontal position, that is, when the test bench stays at the position corresponding to the target irradiation distance, it is in a horizontal state, that is, there is no inclination angle or the inclination angle is small (for example, less than a preset angle), so that the sample to be tested can receive uniform UVC irradiation.

[0178] Figure 11 It is a schematic flowchart of another control method for the lighting device provided by the embodiment of the present application. This method can be executed by the control component 104 of the lighting device 10 as described above. As Figure 11 shown, this method may include the following steps.

[0179] S1101. Before turning on the light source assembly, detect the state of the door body.

[0180] S1102. Determine whether the state of the door body is in the closed state.

[0181] If it is, execute S1103; if not, execute S1104.

[0182] S1103. Turn on the light source assembly.

[0183] S1104. Output a second prompt message, which is used to prompt the user to close the door body.

[0184] In this embodiment, before turning on the light source assembly, it can be determined whether the door body is closed, so as to avoid damage to the test personnel caused by the UVC emitted by the light source assembly when the door body is not closed.

[0185] It can be understood that the control component outputs the first prompt message and the second prompt message in a way that, for example, an alarm can be issued through the alarm of the lighting device, or the first prompt message and the second prompt message can be displayed on the display panel, or the first prompt message and the second prompt message can be output in other ways. The present application does not limit this.

[0186] It can be understood that for the sample to be tested irradiated by the lighting device provided by the embodiment of the present application, the test personnel can use other devices to detect the change in the appearance color and mechanical properties of the sample to be tested. The mechanical properties can include, for example, tensile strength, elongation at break, flexural strength, flexural modulus, impact strength, Vicat, heat distortion, etc. Then, the aging degree of the sample to be tested can be determined based on these parameters, so as to provide data support for whether the sample to be tested is suitable for the UVC sterilization environment according to the aging degree.
