Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more particularly to a refrigerator. Background Technology

[0002] Refrigerators are primarily used for refrigerating and freezing food to extend its freshness. They are an indispensable household appliance. As people's living standards improve, their demands for refrigerators are also increasing.

[0003] In related technologies, refrigerators are equipped with lighting sources to provide illumination for users to retrieve and place items. Some refrigerators also have other light sources, such as sterilization progress indicator lights, to display the sterilization progress of the refrigerator's sterilization module.

[0004] However, the independent arrangement of light sources for different purposes in the refrigerator not only takes up a lot of space and affects the storage capacity of the refrigerator, but also makes the assembly complicated and affects production efficiency. Utility Model Content

[0005] This application provides a refrigerator that integrates a first light source and a second light source.

[0006] In a first aspect, embodiments of this application provide a refrigerator, which includes:

[0007] The enclosure is constructed to form a refrigeration chamber;

[0008] The door is connected to the housing to open or close the refrigeration compartment;

[0009] A light source assembly is disposed within the cooling room; the light source assembly includes:

[0010] A first light source, which is a surface light source, includes a diffusion film and a reflective film located on the back side of the diffusion film, wherein the reflective film is provided with an avoidance opening;

[0011] The second light source extends in a direction parallel to the first light source; the second light source emits a different color than the first light source; the second light source is fixed on the side of the first light source away from the light-emitting surface, and the second light source is opposite to the clearance opening, so that the second light source emits light through the clearance opening toward the light-emitting surface of the first light source.

[0012] In this embodiment, the second light source is fixed to the back of the first light source. The second light source does not need to be fixed to the cabinet; only the first light source needs to be fixed to the cabinet. This simplifies the assembly process of multiple light sources and improves refrigerator production efficiency. The second light source can reuse the diffusion film of the first light source, allowing it to emit light evenly and achieve uniform light distribution. The second light source does not require an additional light-diffusing structure, simplifying its structure and making the light source assembly more compact, reducing installation space requirements. By providing an opening in the reflective film of the second light source to prevent light from entering, the second light source can still emit light through the reflective film without affecting its luminous effect.

[0013] In some embodiments of this application, the first light source includes: a surface light emitter and a first support, wherein the first support is disposed at the edge of the surface light emitter; the surface light emitter includes a diffusion film and a reflective film;

[0014] The second light source includes a lamp board and a second bracket, the second bracket being provided with a light outlet; the lamp board is fixed to the second bracket, and the lamp beads on the lamp board are opposite to the light outlet;

[0015] The second bracket is fixedly connected to the first bracket, and a portion of the second bracket contacts the side of the surface light emitter that is away from the light-emitting surface.

[0016] The second bracket partially contacts the surface light emitter, serving two purposes: firstly, it supports the surface light emitter; secondly, it improves the stability of the connection between the second bracket and the first light source, allowing the second light source to deform in sync with the first light source. This enhances the consistency of their synchronous deformation, thereby improving the stability of the relative position between the lamp panel and the surface light emitter. It also reduces problems such as localized dimming, light leakage, and ghosting caused by inconsistent deformation between the second and first light sources. In some embodiments of this application, the first bracket includes:

[0017] A first frame extends along a first direction and is fixedly connected to one side of the surface light-emitting body;

[0018] Two second borders extend along a second direction, and the two second borders are respectively connected to the two ends of the first border, and the two second borders are fixedly connected to the other two opposite sides of the surface light-emitting body; the second direction intersects the first direction, and the plane containing the second direction and the first direction is parallel to the surface light-emitting body;

[0019] The first frame and the two second frames are respectively fixedly connected to the second bracket.

[0020] In this embodiment, the second bracket is fixedly connected to one first frame and two second frames respectively, forming a three-point fixing method. The fixing structure is stable and reliable, which helps to improve the synchronization between the deformation of the second light source and the deformation of the first light source.

[0021] In some embodiments of this application, the second support includes:

[0022] The bracket body forms the light outlet and is fixedly connected to the lamp panel; the bracket body is in contact with the side of the surface light emitter that is away from the light-emitting surface.

[0023] The first connector is connected to one side of the bracket body along the second direction, and the first connector is fixedly connected to the first frame.

[0024] Two second connectors are respectively connected to both ends of the bracket body along the first direction, and each second connector is fixedly connected to one of the second frames.

[0025] In this embodiment, the second bracket, by fixing the lamp panel to its body, simultaneously makes surface contact with the surface-emitting body, achieving relative positioning between the two and ensuring consistent distance between them. The second bracket is fixedly connected to the first frame by a first connecting body, and to the second frame by a second connecting body. This connection between the second and first brackets avoids affecting the contact between the bracket body and the surface-emitting body.

[0026] In some embodiments of this application, the first connector includes:

[0027] The first connecting portion is formed by bending and extending a portion of the bracket body away from the surface light emitter along one side of the second direction.

[0028] The first fixing part is formed by bending and extending the first connecting part away from the bracket body, and the first fixing part is parallel to the surface light-emitting body; the first fixing part is fixedly connected to the first frame.

[0029] The first positioning part is connected to the end of the first fixing part that is away from the first connecting part, and is opposite to the first connecting part along the second direction and is spaced apart;

[0030] The first frame is provided with a second positioning part, which is located in the gap between the first positioning part and the first connecting part and abuts against the first positioning part.

[0031] In this embodiment, the first connector connects the first fixing part and the bracket body by providing a first connecting part, and is fixedly connected to the first frame by the first fixing part. The first connecting part prevents deformation of the bracket body caused by the fixed connection between the first fixing part and the first frame, which would affect the contact between the bracket body and the surface light emitter. Positioning is achieved by providing a first positioning part and a second positioning part on the first frame, improving the accuracy of the connection between the first connector and the first frame.

[0032] In some embodiments of this application, the second connector includes:

[0033] The second connecting portion is formed by bending and extending the bracket body away from the surface light source at both ends along the first direction.

[0034] The second fixing part is formed by bending and extending the second connecting part away from the bracket body, and the second fixing part is parallel to the surface light-emitting body; the second fixing part is fixedly connected to the second frame.

[0035] The rib portion is disposed on the side of the second fixing portion facing the second frame and abuts against the second frame.

[0036] In this embodiment, a second fixing part is fixedly connected to a second frame, and a second connecting part connects the second fixing part and the bracket body, so that the second fixing part and the bracket body are not on the same surface, reducing the impact on the contact between the bracket body and the surface light emitter caused by the fixed connection between the second fixing part and the second frame. The structural strength of the second fixing part is improved by providing ribs, further reducing deformation caused by the fixed connection between the second fixing part and the second frame.

[0037] In some embodiments of this application, the support body includes:

[0038] The plate body portion is configured to form the light outlet, and the plate body portion is in contact with the surface light-emitting body surface;

[0039] A reinforcing section is provided on the plate body section;

[0040] A fixing column is provided on the main body of the plate and is fixedly connected to the lamp plate;

[0041] A positioning post is provided on the plate body and engages with a positioning hole provided on the lamp plate.

[0042] The bracket body of this embodiment forms a light outlet by setting a plate body portion, which contacts the surface light emitter, thus achieving mutual support between the bracket body and the surface light emitter. The reinforcement portion increases the structural strength of the bracket body and also supports the lamp panel, creating a gap between the lamp panel and the surface light emitter to prevent them from contacting each other and affecting heat dissipation and light emission. The inclusion of fixing posts and positioning posts improves the stability of the lamp panel installation and the ease of installation.

[0043] In some embodiments of this application, a portion of the light-emitting surface of the first light source is provided with a filter film, which is configured to filter the light from the first light source; the filter film is opposite to the second light source.

[0044] By setting a filter film, the light emitted from the opposite portion of the first and second light sources is reduced, thereby improving the light emission effect of the second light source and ensuring its luminous effect.

[0045] In some embodiments of this application, the second light source further includes a cover, which is fixed to the side of the bracket body away from the surface light emitter, and the cover is disposed on the outside of the chip of the lamp board.

[0046] The cover serves to protect and shield the LED chip.

[0047] Secondly, embodiments of this application provide a refrigerator, which includes:

[0048] The enclosure is constructed to form a refrigeration chamber;

[0049] The door is connected to the housing to open or close the refrigeration compartment;

[0050] A light source assembly is disposed on the housing or the door; the light source assembly includes:

[0051] The first light source is arranged in the first plane;

[0052] At least one second light source, the emission color of the second light source being different from the emission color of the first light source; the projection of the second light source in the first plane is located inside the projection of the first light source in the first plane;

[0053] The second light source is fixed to the side of the first light source away from the light-emitting surface, and the second light source is configured to emit light through the first light source toward the light-emitting surface of the first light source.

[0054] With the above configuration, both the second and first light sources can emit light towards the luminous surface of the first light source; and the second light source is hidden behind the first light source, without affecting the appearance of the luminous surface of the first light source. The second light source emits light through the first light source, allowing it to reuse the uniform light structure of the first light source without requiring additional installation. This reduces costs, improves the compactness of the light source assembly, and minimizes the installation space required. Furthermore, since the second light source is fixed to the back of the first light source, it does not need to be fixed to the cabinet or door; only the first light source needs to be fixed to the cabinet or door. This simplifies the assembly process for multiple light sources and improves refrigerator production efficiency. Attached Figure Description

[0079] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0080] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0081] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0082] With continuous technological advancements, people's functional demands for refrigerators are increasing. The types of light sources in refrigerators are gradually increasing. In addition to the conventional lighting sources, refrigerators can also be equipped with sterilization and freshness-preserving light sources. Furthermore, refrigerators can be equipped with other status display light sources, such as sterilization progress indicators and humidification progress indicators; light sources can also be installed on the refrigerator door to enhance its display effect.

[0083] However, the independent arrangement of light sources for different purposes in the refrigerator not only takes up a lot of space and affects the storage capacity of the refrigerator, but also makes the assembly complicated and affects production efficiency.

[0084] In view of this, the refrigerator of this application embodiment is configured with a light source assembly, including a first light source and a second light source, wherein the area of ​​the first light source is larger than the area of ​​the second light source, so that the second light source can be installed on the back of the first light source, allowing the second light source to emit light through the first light source. This improves the integration of the second and first light sources, eliminates the need for a light-diffusing structure for the second light source, makes the light-diffusing assembly structure compact, and reduces the installation space occupied. Furthermore, during refrigerator assembly, since the second light source is installed on the back of the first light source, there is no direct connection between the second light source and the refrigerator; only the first light source needs to be fixed to the refrigerator, which simplifies refrigerator assembly and improves refrigerator production efficiency.

[0085] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0086] Combination Figure 1 and Figure 2 Some embodiments of this application provide a refrigerator, which includes a cabinet 100, which can be configured to form a refrigeration compartment 101 with a front opening for storing items.

[0087] Multiple refrigeration compartments 101 can be provided to expand storage space. Depending on the storage temperature of the refrigeration compartments 101, they can include at least one refrigerated compartment and at least one frozen compartment. The internal temperature of the refrigerated compartment can be maintained between approximately 0°C and 5°C for storing items in refrigeration mode; the internal temperature of the frozen compartment can be maintained between approximately -30°C and 0°C for storing items in freezing mode.

[0088] In some possible implementations, at least one of the cooling chambers 101 may also be configured as a vacuum chamber or a variable temperature chamber, etc., which will not be described in detail in the embodiments of this application.

[0089] For example, there may be two refrigeration compartments 101, which may be stacked vertically or arranged side by side horizontally. One of them may be a refrigerator compartment and the other may be a freezer compartment.

[0090] In some embodiments, combined with Figure 1 and Figure 2 The cabinet 100 may include a liner and a shell. The liner may be configured to form a refrigeration compartment 101 with a front opening, which serves as an access port. The shell may be attached to the outside of the liner to form the appearance of the refrigerator.

[0091] The cabinet 100 may also include a cabinet insulation layer, which can be disposed between the cabinet liner and the cabinet shell. The cabinet insulation layer can insulate the cooling compartment 101 to minimize heat exchange between the cooling compartment 101 and the outside of the refrigerator, which helps to ensure the cooling effect of the refrigerator.

[0092] The refrigerator of this embodiment may further include a refrigeration system for reducing the air temperature in the refrigeration compartment 101. Exemplarily, the refrigeration system may be housed within the cabinet 100. The refrigeration system may include a compressor, condenser, expansion valve, and evaporator connected in a cycle.

[0093] During refrigeration system operation, the compressor compresses refrigerant vapor to generate high-temperature, high-pressure refrigerant vapor, which is then transported to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then transported to the expansion valve. The expansion valve reduces the pressure of the refrigerant liquid, transforming the high-pressure, low-temperature refrigerant liquid into a low-pressure, low-temperature refrigerant liquid, which is then transported to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside the refrigeration compartment 101.

[0094] Continue to refer to Figure 1The refrigerator in this embodiment may further include a door 200, which is connected to the cabinet 100 to open or close the storage compartment. Exemplarily, the door 200 and the cabinet 100 are hinged together.

[0095] Each storage room can be equipped with a corresponding door 200; or, as... Figure 1 As shown, each storage room can be equipped with two doors 200, which can rotate in opposite directions to open or close the storage room.

[0096] In some embodiments of this application, such as Figure 3 As shown, the storage room is equipped with a freezer drawer 110, the outer end of which forms a door, eliminating the need for an additional door. The freezer drawer 110 is used to store food.

[0097] In some embodiments of this application, the door 200 may include a door panel, at least a portion of which is light-transmitting, forming a light-transmitting area. The door panel is located on the outer surface of the door 200 opposite to the housing 100, forming the appearance structure of the door 200. Exemplarily, the door panel may be a glass panel.

[0098] The door body 200 may also include an inner door liner, which is spaced apart and positioned opposite each other on the inside of the door panel, with the inner door liner facing the storage compartment. The inner door liner may be provided with ribs for mounting door shelves to increase the refrigerator's storage capacity.

[0099] The door body 200 may also include an outer frame, which is located at the edge between the door panel and the inner liner. The outer frame, the door panel, and the inner liner together form a door cavity, in which electrical components can be installed to increase the refrigerator's functionality. The door cavity is also equipped with an insulation structure, such as an insulation layer, to improve the insulation performance of the door body 200.

[0100] The refrigerator in this embodiment may also include a light source assembly 300. For example... Figure 2 As shown, the light source assembly 300 can be disposed within the cooling chamber 101; for example, the light source assembly 300 can be disposed on the rear wall of the cooling chamber 101. Of course, the light source assembly 300 can also be disposed on the left or right side wall of the cooling chamber 101, etc.

[0101] like Figure 3 As shown, the light source component 300 can be installed on the door body 200, opposite to the light-transmitting area of ​​the door panel.

[0102] like Figure 4As shown, the light source assembly 300 may include a first light source 310 and at least one second light source 320, wherein the second light source 320 emits a different color of light than the first light source 310. For example, the first light source 310 may emit white light and the second light source 320 may emit blue light; or, for another example, the first light source 310 may emit red light and the second light source 320 may emit yellow light, etc.

[0103] This application embodiment does not limit the emission color of the first light source 310 and the second light source 320, and the colors of the first light source 310 and the second light source 320 can be set according to actual needs.

[0104] The first light source 310 can be a lighting source, a sterilization source, a freshness-preserving source, etc. The second light source 320 can be a sterilization progress display source, a humidification progress display source, etc. The functions of the first light source 310 and the second light source 320 are not limited to the above-described examples.

[0105] The first light source 310 is arranged within the first plane. For example... Figure 3 As shown, when the light source assembly 300 is arranged on the door body 200, the first plane can be set parallel to the door body 200. Figure 2 As shown, when the light source assembly 300 is arranged on the rear wall of the cooling chamber 101, the first plane can be parallel to the rear wall of the cooling chamber 101.

[0106] For example, the first light source 310 is a surface light source with a large luminous area, which can provide better lighting effects. When the first light source 310 is installed in the cooling room 101, the first light source 310 can be a lighting source, and the large luminous area of ​​the surface light source can provide better lighting.

[0107] In some embodiments of this application, the second light source 320 extends along a direction within the first light source 310, which can be understood as the second light source 320 extending in a direction parallel to the first light source 310. Combined with... Figure 4 The first light source 310 is arranged on the first plane (corresponding to Figure 4 When the second light source 320 is in the XY plane, it can be along the length direction of the first light source 310 (corresponding to the XY plane). Figure 4 The second light source 320 extends along the width direction of the first light source 310 (corresponding to the X-axis direction). Figure 4 The second light source 320 can extend along other directions within the first light source 310, for example, the angle between the extension direction of the second light source 320 and the length direction of the first light source 310 is an acute angle.

[0108] In some embodiments of this application, the projection of the second light source 320 onto the first plane is located inside the projection of the first light source 310 onto the first plane. For example... Figure 4As shown, the projection of the second light source 320 onto the first plane is the first projection, and the projection of the first light source 310 onto the first plane is the second projection. The first projection is located inside the second projection. With this configuration, when the second light source 320 is positioned behind the first light source 310, the second light source 320 can be hidden behind the first light source 310 and not be exposed.

[0109] Here, the back side of the first light source 310 refers to the side that is away from the light-emitting surface of the first light source 310.

[0110] exist Figure 4 The example shown uses a single second light source 320 as an illustration. However, this is not limiting. Multiple second light sources 320 can be provided. Multiple second light sources 320 are staggered within the plane of the first light source 310 to avoid overlapping between two second light sources 320 and affecting the light emission effect.

[0111] For example, when the second light source 320 extends along the length direction of the first light source 310, a plurality of second light sources 320 may be arranged at intervals along the width direction of the first light source 310.

[0112] It should be noted that when multiple second light sources 320 are set, the emission color of each second light source 320 can be different. This can make it easier for users to judge the function of the refrigerator by different colors of light, and can also avoid mutual interference between the light from the second light sources 320.

[0113] For example, two second light sources 320 are provided. One second light source 320 is used to indicate the sterilization progress and can emit blue light; the other second light source 320 is used to indicate the humidity of the preservation chamber and can emit green light.

[0114] In this embodiment, the second light source 320 is fixed to the side of the first light source 310 away from the light-emitting surface, and the second light source 320 is configured to emit light through the first light source 310 toward the light-emitting surface of the first light source 310.

[0115] Thus, both the second light source 320 and the first light source 310 can emit light towards the light-emitting surface of the first light source 310; and the second light source 320 is hidden behind the first light source 310, without affecting the appearance of the light-emitting surface of the first light source 310. The second light source 320 emits light through the first light source 310, allowing it to reuse the uniform light structure of the first light source 310 without additional installation. This reduces costs and improves the structural compactness of the light source assembly 300, minimizing its installation space requirements. Furthermore, since the second light source 320 is fixed to the back of the first light source 310, it does not need to be fixed to the cabinet 100 or door 200; only the first light source 310 needs to be fixed to either the cabinet 100 or door 200. This simplifies the assembly process for multiple light sources and improves refrigerator production efficiency.

[0116] In this embodiment of the application, the first light source 310 includes a diffusion film and a reflective film located on the back side of the diffusion film. The diffusion film is configured to allow light to propagate in a plane and be uniformly emitted from a surface through scattering, refraction and reflection.

[0117] The reflective film is constructed to recycle light rays with incorrect polarization, allowing the light to exit from the light-emitting surface, which helps to improve brightness and optical efficiency.

[0118] In this embodiment, the reflective film is provided with an avoidance opening. The second light source 320 is fixed to the side of the first light source 310 away from the light-emitting surface, and the second light source 320 is opposite to the avoidance opening, so that the second light source 320 emits light through the avoidance opening toward the light-emitting surface of the first light source 310.

[0119] With this configuration, the second light source 320 can reuse the diffusion film of the first light source 310, allowing it to emit light evenly and achieve uniform light distribution. The second light source 320 does not require an additional light-diffusing structure, simplifying its structure and making the light source assembly 300 more compact, reducing installation space requirements. By providing openings in the reflective film of the second light source 320 to prevent light from passing through, the second light source 320 can still emit light without affecting its luminous efficiency.

[0120] In some embodiments, the first light source 310 is a surface light source, and the surface light source is a direct-lit light source. The substrate with the LED array is provided with an opening to avoid the emission of the second light source 320.

[0121] In other embodiments, the first light source 310 is a surface light source, and the surface light source has a side-lit structure. The LED light strip is located on one side of the surface light source, and the light from the LED light strip is diffused to the light-emitting surface through a light guide plate.

[0122] In some possible implementations of this application, the first light source 310 adopts a side-lit surface light source structure, which is thinner and helps to reduce the space occupied during installation.

[0123] Combination Figure 5 In some embodiments of this application, the first light source 310 includes a surface light emitter 311 and a first support 400, wherein the first support 400 is disposed at the edge of the surface light emitter 311.

[0124] The surface light emitter 311 may include LED light strips, light guide plates, diffusion films, and reflective films. Under the action of the light guide plate, diffusion film, and reflective film, the light from the LED light strip is diffused into uniform surface light and emitted.

[0125] The second light source 320 includes a lamp board 321 and a second bracket 500, the second bracket 500 being provided with a light outlet 501; the lamp board 321 is fixed to the second bracket 500, and the lamp beads on the lamp board 321 are opposite to the light outlet 501. The lamp board 321 can be snapped onto the second bracket 500, the connection method is simple; the lamp board 321 can also be fixed to the second bracket 500 with screws, the connection method is stable and reliable.

[0126] The second bracket 500 is fixedly connected to the first bracket 400, and a portion of the second bracket 500 contacts the side of the surface light emitter 311 that is away from the light-emitting surface. The second bracket 500 and the first bracket 400 can be fixedly connected by means of snap-fit, adhesive, or screw connection. The fixed connection between the second bracket 500 and the first bracket 400 prevents the fixing structure of the second light source 320 from affecting the light emission of the first light source 310.

[0127] Furthermore, the second support 500 partially contacts the surface light source 311, which serves to support the surface light source 311 and improve the stability of the connection between the second support 500 and the first light source 310. This allows the second light source 320 to deform in sync with the deformation of the first light source 310, improving the consistency of the synchronous deformation of the second light source 320 and the first light source 310. This, in turn, improves the stability of the relative position between the lamp panel 321 and the surface light source 311, reducing problems such as local dimming, light leakage, and ghosting caused by inconsistent deformation of the second light source 320 and the first light source 310.

[0128] Continue to refer to Figure 5 In some embodiments of this application, the first bracket 400 includes a first frame 410, which extends along a first direction and is fixedly connected to one side of the surface light emitter 311.

[0129] The second light source 320 can extend along the first direction.

[0130] The first bracket 400 also includes two second frame edges 420, which extend along a second direction. The two second frame edges 420 are respectively connected to the two ends of the first frame edge 410, and the two second frame edges 420 are fixedly connected to the other two opposite sides of the surface light source 311. The second direction intersects with the first direction, and the plane containing the second direction and the first direction is parallel to the surface light source 311.

[0131] The light strip of the surface light source 311 can be set inside the first frame 410 or inside the second frame 420.

[0132] In some implementations, the first bracket 400 may further include a third frame, which is parallel to the first frame 410 and located on the side of the surface light emitter 311 opposite to the first frame 410. The light strip of the surface light emitter 311 may be disposed within the third frame.

[0133] The first direction can correspond to Figure 5 In the X-axis direction, the second direction can correspond to Figure 5 In the Y-axis direction. The surface light emitter 311 is arranged parallel to the XY plane, and the surface light emitter 311 is a rectangular light emitter.

[0134] The second bracket 500 extends to the first frame 410 and the second frame 420 respectively, so that the first frame 410 and the two second frames 420 are fixedly connected to the second bracket 500 respectively.

[0135] The methods for fixing the first frame 410 to the second bracket 500, and the methods for fixing the second frame 420 to the second bracket 500, include, but are not limited to, snap-fit, screw connection, and adhesive connection.

[0136] For example, the first frame 410 and the second bracket 500 are fixedly connected by screws; the second frame 420 and the second bracket 500 are fixedly connected by screws, and the connection method is stable and reliable.

[0137] In this embodiment, the second bracket 500 is fixedly connected to a first frame 410 and two second frames 420 respectively, forming a three-point fixing method. The fixing structure is stable and reliable, which helps to improve the synchronization of the deformation of the second light source 320 and the deformation of the first light source 310.

[0138] Combination Figure 6 In some embodiments of this application, the second bracket 500 includes a bracket body 510 extending along a first direction. The bracket body 510 is configured to form a light outlet 501 and is fixedly connected to the lamp panel 321.

[0139] Reference Figure 6The second support 500 also includes a first connector 520, which is connected to one side of the support body 510 along the second direction.

[0140] Reference Figure 6 The second support 500 also includes two second connectors 530, which are respectively connected to the two ends of the support body 510 along the first direction.

[0141] For example, the second connector 530, the first connector 520 and the bracket body 510 are integrally formed as a single piece to improve the structural strength of the second bracket 500 and facilitate processing and forming.

[0142] Reference Figure 7 and Figure 8 The bracket body 510 contacts the side of the surface-emitting body 311 facing away from the light-emitting surface. The side of the bracket body 510 facing the surface-emitting body 311 forms a plane and contacts the surface-emitting body 311. The surface contact between the bracket body 510 and the surface-emitting body 311 provides mutual support, improving the consistency of deformation between them and ensuring the consistency of the distance between the lamp panel 321 and the surface-emitting body 311. When the first light source 310 deforms along its thickness direction, the second light source 320 deforms accordingly without producing localized brightness variations, thus ensuring the display effect of the second light source 320.

[0143] Combination Figure 9 and Figure 10 The first connector 520 is fixedly connected to the first frame 410. For example, the first connector 520 and the first frame 410 are respectively provided with connecting holes, and screws are threadedly connected to the connecting holes of the first connector 520 and the first frame 410 respectively, thereby realizing the fixed connection between the first connector 520 and the first frame 410.

[0144] like Figure 10 As shown, the first frame 410 forms a first mounting cavity 411 with an opening on one side. One side of the surface light-emitting body 311 is inserted into the first mounting cavity 411 to achieve a fixed connection between the first frame 410 and the surface light-emitting body 311.

[0145] Continue to refer to Figure 10 In some embodiments of this application, the first connector 520 includes a first connector 521, wherein a portion of the back surface light emitter 311 of the bracket body 510 is bent and extended along one side of the second direction to form the first connector 521. The first connector 521 is located on one side of the bracket body 510 along the second direction, and the first connector 521 may be disposed perpendicular to the bracket body 510.

[0146] Reference Figure 10The first connector 520 may also include a first fixing part 522. The first connector 521 bends and extends away from the bracket body 510 to form the first fixing part 522. The first fixing part 522 is parallel to the surface light emitter 311. The first fixing part 522 is fixedly connected to the first frame 410.

[0147] For example, the first fixing part 522 is provided with a first fixing hole 5221, and the first frame 410 is provided with a first connecting hole 412. The screw is threadedly connected to the first fixing hole 5221 and the first connecting hole 412 respectively, so as to realize the fixed connection between the first fixing part 522 and the first frame 410.

[0148] Continue to refer to Figure 10 The first connecting body 520 may also include a first positioning part 523, which is connected to one end of the first fixing part 522 away from the first connecting part 521 and is opposite to the first connecting part 521 in the second direction and is spaced apart.

[0149] Reference Figure 10 The first frame 410 is provided with a second positioning part 413, which is located in the gap between the first positioning part 523 and the first connecting part 521 and abuts against the first positioning part 523.

[0150] The second positioning part 413 can be a strip-shaped structure extending along the first direction.

[0151] With the cooperation of the first positioning part 523 and the second positioning part 413, the second bracket 500 can be initially positioned on the first bracket 400, which helps to improve the accuracy of the assembly of the second bracket 500 and the first bracket 400.

[0152] In some embodiments, a first rib 414 may also be provided on the first frame 410. The first rib 414 may extend along a first direction and is located on the side of the second positioning part 413 opposite to the first positioning part 523. A first connecting hole 412 is located between the first rib 414 and the second positioning part 413.

[0153] The first rib 414 and the second positioning part 413 can both improve the structural strength of the first frame 410 and reduce the possibility that the fixed connection between the first connector 520 and the first frame 410 will affect the deformation of the first frame 410.

[0154] In this embodiment, the first connector 520 connects the first fixing part 522 and the bracket body 510 by providing a first connecting part 521, and the first fixing part 522 is fixedly connected to the first frame 410. The first connecting part 521 can prevent the first fixing part 522 from being fixedly connected to the first frame 410, which would cause deformation of the bracket body 510 and affect the contact between the bracket body 510 and the surface light emitter 311. Positioning is achieved by providing a first positioning part 523 and a second positioning part 413 of the first frame 410, thereby improving the accuracy of the connection between the first connector 520 and the first frame 410.

[0155] Reference Figure 11 and Figure 12 Each second connector 530 is fixedly connected to one of the second frame 420. For example, the second connector 530 and the second frame 420 are respectively provided with connecting holes, and screws are threadedly connected to the connecting holes of the second connector 530 and the second frame 420 respectively, thereby realizing the fixed connection between the second connector 530 and the second frame 420.

[0156] In this embodiment, the second bracket 500, by fixing the lamp plate 321 to the bracket body 510, simultaneously makes surface contact with the surface light emitter 311, achieving relative positioning between the two and ensuring the consistency of the distance between the lamp plate 321 and the surface light emitter 311. The second bracket 500 is fixedly connected to the first frame 410 by a first connector 520 and to the second frame 420 by a second connector 530. This fixed connection between the second bracket 500 and the first bracket 400 avoids affecting the contact between the bracket body 510 and the surface light emitter 311.

[0157] like Figure 12 As shown, the second frame 420 forms a second mounting cavity 421 with an opening on one side. One side of the surface light emitter 311 is inserted into the second mounting cavity 421 to achieve a fixed connection between the second frame 420 and the surface light emitter 311.

[0158] Continue to refer to Figure 12 The second connector 530 includes a second connector 531, wherein the bracket body 510 extends away from the surface light emitter 311 at both ends along the first direction to form the second connector 531. The second connector 531 is located at the end of the bracket body 510 along the first direction and can be arranged perpendicular to the bracket body 510.

[0159] Reference Figure 12The second connector 530 may also include a second fixing part 532. The second connector 531 bends and extends away from the bracket body 510 to form the second fixing part 532. The second fixing part 532 is parallel to the surface light emitter 311. The second fixing part 532 is fixedly connected to the second frame 420.

[0160] For example, the second fixing part 532 is provided with a second fixing hole 5321, and the second frame 420 is provided with a second connecting hole 422. Screws are threadedly connected to the second fixing hole 5321 and the second connecting hole 422 respectively, so as to realize the fixed connection between the second fixing part 532 and the second frame 420.

[0161] Reference Figure 13 The second connector 530 may also include a rib portion 533, which is disposed on the side of the second fixing portion 532 facing the second frame 420 and abuts against the second frame 420.

[0162] The rib portion 533 can improve the structural strength of the second connector 530, thereby improving the reliability of the connection between the second connector 530 and the second frame 420.

[0163] For example, the ribs may extend along the extension direction of the support body 510, and multiple ribs may be spaced apart along the second direction to further improve the structural strength of the second connector 530.

[0164] An extension 5322 may also be provided on the side of the second fixing part 532 facing the second frame 420. The second fixing hole 5321 passes through the extension 5322 to extend the axial length of the second fixing hole 5321 and increase the threaded connection length between the second fixing hole 5321 and the screw.

[0165] In this embodiment, a second fixing part 532 is fixedly connected to the second frame 420, and a second connecting part 531 connects the second fixing part 532 and the bracket body 510, so that the second fixing part 532 and the bracket body 510 are not on the same plane, reducing the impact on the contact between the bracket body 510 and the surface light emitter 311 caused by the fixed connection between the second fixing part 532 and the second frame 420. The rib part 533 is provided to improve the structural strength of the second fixing part 532, further reducing deformation caused by the fixed connection between the second fixing part 532 and the second frame 420.

[0166] Reference Figure 14 and Figure 15 In some embodiments of this application, the support body 510 includes a plate body portion 511, which extends along a first direction. The plate body portion 511 is configured to form a light emission port 501, and the plate body portion 511 is in surface contact with the surface light emitter 311.

[0167] The plate body portion 511 is connected to the first connecting body 520 on one side along the second direction, wherein the plate body portion 511 is connected to the first connecting portion 521 on one side along the second direction.

[0168] The two ends of the plate body portion 511 along the first direction are respectively connected to the second connecting body 530, wherein the two ends of the plate body portion 511 along the first direction are respectively connected to the second connecting portion 531.

[0169] The support body 510 may also include a reinforcing part 512, which is disposed on the plate body part 511 and serves to improve the structural strength of the plate body part 511.

[0170] The reinforcing portion 512 may be a rib provided on the plate body portion 511. The reinforcing portion 512 may include ribs extending along a first direction, and may also include ribs extending along a second direction. This application embodiment does not limit the number or extension direction of the reinforcing portions 512.

[0171] The bracket body 510 may also include a fixing post 513, which is disposed on the plate body portion 511 and fixedly connected to the lamp plate 321. The fixing post 513 is configured to form a threaded hole, and a screw passes through the connecting hole on the lamp plate 321 and is threadedly connected to the threaded hole of the fixing post 513, thereby fixing the lamp plate 321 to the fixing post.

[0172] To improve the reliability of the lamp panel 321 installation, multiple fixing posts 513 can be provided, and multiple fixing posts 513 can be arranged in an array on the panel body 511.

[0173] The bracket body 510 may also include a positioning post 514. The positioning post 514 is disposed on the plate body 511 and cooperates with the positioning hole provided on the lamp plate 321. Through the cooperation of the positioning post 514 and the positioning hole, the position of the lamp plate 321 and the bracket body 510 is defined, so that the installation of the lamp plate 321 is more accurate.

[0174] The bracket body 510 of this embodiment forms a light outlet 501 by providing a plate body portion 511, which contacts the surface light emitter 311, thus achieving mutual support between the bracket body 510 and the surface light emitter 311. A reinforcing portion 512 is provided to improve the structural strength of the bracket body 510, and the reinforcing portion 512 also serves to support the lamp plate 321, ensuring a gap between the lamp plate 321 and the surface light emitter 311 to prevent them from contacting each other and affecting heat dissipation and light emission. The fixing post 513 and positioning post 514 are provided to improve the stability of the lamp plate 321 installation and the convenience of installation operations.

[0175] In some possible implementations of this application, a filter film is provided on a portion of the light-emitting surface of the first light source 310, and the filter film is configured to filter the light from the first light source 310; the filter film is opposite to the second light source 320.

[0176] By setting a filter film, the light emitted from the opposite portion of the first light source 310 and the second light source 320 is reduced, thereby improving the light emission effect of the second light source 320 and ensuring the luminous effect of the second light source 320.

[0177] For example, the first light source 310 emits white light for illumination; the second light source 320 emits blue light for displaying the sterilization progress. The filter film can filter the white light, making the blue light more prominent and improving the display effect of the sterilization progress.

[0178] The filter film can be a film layer sprayed onto the light-emitting surface of the first light source 310, or it can be a film layer attached to the light-emitting surface of the first light source 310.

[0179] The pattern of the filter film can be a variety of patterns such as starry sky patterns or circular patterns, in order to enhance the display effect of the second light source 320.

[0180] To enhance the display effect of the second light source 320, a marquee effect can be achieved by controlling the light panel 321. Of course, the second light source 320 can also employ other lighting effects, such as flashing or a constantly lit progress bar mode.

[0181] Continue to refer to Figure 5 In some implementations of this application, the second light source 320 also includes a cover 322, which is fixed to one side of the light-emitting body 311 on the opposite side of the bracket body 510, and the cover 322 covers the outside of the chip of the lamp board 321, thus protecting and shielding the chip of the lamp board 321.

[0182] The chip in the lamp board 321 controls the working status of each LED on the lamp board 321. The chip in the lamp board 321 can be located in the middle of the lamp board 321, which facilitates the design and wiring layout of the lamp board 321.

[0183] The cover 322 and the bracket body 510 can be snapped together, a simple and reliable connection method. Of course, the cover 322 and the bracket body 510 can also be connected by screws, a stable connection method.

[0184] In some possible assembly processes, the lamp board 321 is first fixed to the bracket body 510, and the cover 322 is fixed to the bracket body 510 to protect the chip of the lamp board 321 and prevent the chip of the lamp board 321 from being bumped during the assembly process.

[0185] Then, the second bracket 500 is fixed to the first bracket 400 of the first light source 310. That is, the first connector 520 and the first frame 410 are fixedly connected, and the second connector 530 and the second frame 420 are fixedly connected, reducing the possibility of deformation and shaking of the lamp panel 321.

[0186] Then, the light source assembly 300 is assembled to the cabinet 100 or the door 200. For example, the light source assembly 300 is installed on the air duct panel of the refrigerator compartment.

[0187] A filter film can be sprayed onto the light-emitting surface of the first light source 310 to highlight the light-emitting effect of the second light source 320.
