It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] It should be noted that when an element is referred to as being "disposed on", "connected to", another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0041] It should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] The terms "first" and "second" are used for descriptive purposes only and are not used to imply relative importance.

[0043] The first embodiment of the utility model provides a surface light source with a pattern light, which can be installed in a refrigerating chamber of a refrigerator and used for lighting inside the refrigerator.

[0044] refer to Figure 1a , Figure 1b and Figure 2 The surface light source with graphic lights includes an LED light strip 1 and a surface light source main body, wherein the surface light source main body is a multi-layer structure, including an appearance layer panel 2, a diffusion layer panel 3, a light guide layer panel 4 and a reflection layer panel 5 that are sequentially bonded together. The LED light strip 1 is connected to an external power supply via a terminal 9, is bonded to the surface light source main body, emits light after being powered on, and is used for emitting light from the surface light source.

[0045] In order to solve the problem of installing the LED light bar 1, in some embodiments of the utility model, the surface light source further includes a heat dissipation bracket 8, the heat dissipation bracket 8 forms a U-shaped groove, the LED light bar 1 and the surface light source body are installed in the U-shaped groove, and the installation structure is referenced Figure 3 and Figure 4 The LED light bar is installed in the bottom part of the U-shaped groove of the heat dissipation bracket and is arranged along the edge part of the surface light source body. The two side panels of the groove structure form a fixed structure with the surface light source body.

[0046] The surface light source with a graphic light also includes an image light block 6, the structure of which is shown in FIG. Figure 5 The image light block 6 is connected to a power source and emits light after being powered on. The shape of the image light block 6 can be designed as needed, for example, it can be designed into various shapes such as a square column, a triangle or a pentagon. The surface of the image light block 6 can be designed with various styles of graphics such as brand LOGO graphics, and the corresponding graphics can be displayed when it emits light. The LOGO can be set in various schemes as needed, and various colors such as blue, yellow and color can be used, and it can also be designed as a real-time changing lighting effect. At the same time, it can also be set as a germicidal lamp as needed.

[0047] Since the overall thickness of the surface light source is not thick, and in order to meet the requirements of installation inside the refrigerator, the thickness of the image light block 6 should not be too thick, and can usually be designed to be 8 to 12 mm.

[0048] In order to install the image light block 6, corresponding hole structures are provided on the light guide layer panel 4 and the reflective layer panel 5, which are: the diffusion layer panel hole structure 301, the light guide layer panel hole structure 401 and the reflective layer panel hole structure 501. The diffusion layer panel hole structure 301 and the reflective layer panel hole structure 501 have the same size, and the shape and size of the reflective layer panel hole structure 501 are adapted to the shape and size design of the image light block 6, so as to ensure that the image light block 6 can be fixedly installed in the hole structure, the diffusion layer panel hole structure 301. After the image light block 6 is inserted into the hole structure, it can be fixed at the edge by an adhesive structure.

[0049] In some embodiments of the present invention, the image light block 6 and the LED light strip 1 are independently connected to a power source and can be independently controlled to emit light.

[0050] The light-guiding layer panel 4 is provided with light-emitting points to form a light-emitting area for diffusing the light emitted by the LED light bar 1. However, since the LED light bar 1 and the image light block 6 are independent light-emitting components, in order to avoid the influence of the light emitted by the two, a light-transmitting area 401 is designed on the light-guiding layer panel 4. The position of the light-transmitting area corresponds to the position of the hole structure 501 of the reflective layer panel, and no light-emitting points are provided at the position where the light-transmitting area 401 is located. This structure can ensure that the light-guiding layer panel 4 can diffuse the light emitted by the LED light bar 1 without affecting the light penetration of the image light block 6, thereby avoiding the influence of the light emitted by the LED light bar 1 and the image light block 6.

[0051] Since the surface light source works in a humid environment, in order to avoid damaging the work of the LED light bar 1 and the image light block 6, a sealing layer panel 7 is further provided at the rear of the surface light source body. The sealing layer panel 7 is provided on the outside of the reflective layer panel 5 and is sealed to the surface light source body to prevent water vapor from entering the surface light source body and damaging the surface light source. In some embodiments, the sealing layer panel 7 can be a film.

[0052] In some embodiments of the utility model, a hole structure 701 is provided on the sealing layer panel 7, and the hole structure 701 on the sealing layer panel corresponds to the hole structure on the light guide layer panel, the diffusion layer panel and the reflection layer panel. The image light block 6 passes through the hole structure 701 on the sealing layer panel, and sealing treatment is performed on the fitting parts of the image light block 6 and each hole structure.

[0053] The second embodiment of the utility model provides a refrigerator, comprising the surface light source provided by the first embodiment above. The surface light source is fixed on the refrigerator air duct back plate and is used for lighting the interior of the refrigerator refrigeration chamber.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
