The number of the lamp beads 112 may be one or more, wherein when the number of the lamp beads 112 is multiple, the arrangement manner of the lamp beads 112 on the lamp panel 111 may be aggregation arrangement, random dispersion arrangement, array arrangement, or radial arrangement with a certain point as a center, so as to correspondingly enhance the illumination intensity and enlarge the illumination area of the light source light; the lamp beads 112 may protrude from the surface of the lamp panel 111, or may be embedded in the main body of the lamp panel 111. In other embodiments, the light emitting device 110 may further include a lamp cover to collect the light emitted from the light source 112. The lamp beads 112 can adopt different color temperatures and different colors; the lamp bead 112 can be set to a normally-on mode, a breathing mode or a switching mode under triggering through a control circuit; the control circuit may be provided on the lamp panel 111. It should be noted that the control circuit may be an independent circuit that is configured to distinguish the control system of the refrigerator, or may be electrically connected to the control system of the refrigerator to form a component of the control system of the refrigerator; the technology of the control circuit is mature technology and is not described herein.
In view of the above, in order to avoid the optical path loss, the distance between the light emitting side and the first light incident side is set to be as close as possible, and based on this, in an embodiment, the lamp panel 111 is connected to the first light guide plate 120 through a detachable connection structure. Can dismantle connection structure's setting, not only do benefit to the dismouting replacement between lamp plate 111 and the first light guide plate 120, make things convenient for respective maintenance, and, can dismantle connection structure fixes the relative position between lamp plate 111 and the first light guide plate 120 to a certain extent, also be the relative position between luminous side and the first income plain noodles 121, avoid because the two misplaces or slope, lead to in the unable first light guide plate 120 that gets into of light source light that sends through luminous side, influence the quality of the light that sends from first play plain noodles 122 then.
Of course, the technical solution of the detachable structure that realizes the above functions is various, for example, the detachable structure may be screwed and fixed by a screw connector, or may be adhered and fixed by providing an adhesive layer between the lamp panel 111 and the first light guide plate 120. In an embodiment, the detachable connection structure includes a buckle 141 and a buckle hole 142 that are fastened to each other, one of the buckle 141 and the buckle hole 142 is disposed on the lamp panel 111, and the other is disposed on the first light guide plate 120. Explaining at the lamp plate 111 with the setting of buckle 141 at the first income plain noodles 121 of first light guide plate 120, detaining the setting of hole 142 as the example, buckle 141 can be the elasticity buckle, and under the exogenic action, buckle 141 elastic deformation is in order to pass through detaining hole 142 smoothly, then after removing the exogenic action, buckle 141 resumes deformation and carries out the lock in order to detain hole 142, realizes the mutual knot between lamp plate 111 and the first light guide plate 120 and holds, has simple structure and convenient operation's advantage.
Further, in an embodiment, the lamp panel 111 or the first light guide plate 120 is provided with a plurality of supporting bosses 143 at a position spaced apart from the detachable connection structure, and the lamp panel 111 and the first light guide plate 120 are abutted by the plurality of supporting bosses 143. Specifically, support boss 143 is located between lamp plate 111 and first light guide plate 120, can form on lamp plate 111, form on first light guide plate 120 or form simultaneously on lamp plate 111 and first light guide plate 120 for with the distance restriction between lamp plate 111 and the first light guide plate 120 in required range, and cooperate buckle 141 and detain hole 142, realize the better effect of holding of detaining between lamp plate 111 and the first light guide plate 120. It should be noted that the supporting boss 143 may be integrally formed with the lamp panel 111 and/or the first light guide plate 120, or may be separately formed with the lamp panel 111 and/or the first light guide plate 120; the lamp panel 111 is provided with a light emitting region in which the lamp beads 112 are arranged, and the plurality of supporting bosses 143 are correspondingly arranged around the periphery of the light emitting region so as not to influence the light of the light source to enter the first light incident surface 121; of course, the supporting boss 143 may be made of a transparent material, such as acrylic plate or transparent glass, which also does not block the light of the light source.
Further, in an embodiment, the number of the detachable connection structures is at least two, and the two detachable connection structures are disposed at two ends of the lamp panel 111 and the first light guide plate 120 correspondingly, or surround the periphery of the light emitting area, so as to connect the lamp panel 111 and the first light guide plate 120 in the circumferential direction of the whole lamp panel 111 and the first light guide plate 120, so that the connection between the lamp panel 111 and the first light guide plate 120 is more stable and is not prone to generate deflection.
Referring to fig. 4 to 6, in an embodiment, the second light guide plate 130 has two opposite side surfaces, one of which is configured as a second light emitting surface 132, and the other of which is configured as a light reflecting surface 133.

The inclined light reflecting surface 133 is used for reflecting most of the light entering the second light guide plate 130 from the second light incident surface 131 to the second light emitting surface 132, and emitting the light through the second light emitting surface 132.
Specifically, in one embodiment, the light reflecting surface 133 is provided with a relief structure 134. The concave-convex structure 134 may be configured as a film-like structure fixed on the light reflecting surface 133, or may be formed by directly etching on the light reflecting surface 133 by using a technique such as laser; the concave-convex structure 134 may be a plurality of convex portions and/or a plurality of concave portions disposed on the light reflecting surface 133, the shape of the convex portions and/or the concave portions is not limited, and the convex portions and/or the concave portions may be point-shaped or strip-shaped, and the outer surfaces of the convex portions and/or the concave portions are preferably arc-shaped, specifically, for example, the concave-convex structure 134 is disposed as a wave-shaped structure formed on the light reflecting surface 133. The concave-convex structure 134 has a higher reflectivity, and after the light irradiates the concave-convex structure 134, the light is reflected from various angles, so that the light is further uniformly dispersed, and the light is emitted through the second light emitting surface 132 as far as possible.
In the above, the light source assembly 100 may be directly mounted on the body of the refrigerator, or may be mounted on the body of the refrigerator through a mounting structure; when the light source assembly 100 is installed on the main body of the refrigerator through an installation structure, the installation structure may be a structure specially adapted to the light source assembly 100, or an existing structure on the main body of the refrigerator. Therefore, referring to fig. 7 to 11, the present invention further provides a display module 200, in which the display module 200 includes a mounting body 210 and the light source module 100, and the light source module 100 is disposed on the mounting body 210.
