Preferred embodiments of a surface emitting structure and a refrigerator having the same according to the present invention will be described in detail below with reference to the accompanying drawings. In the description of the drawings, the same or corresponding portions are denoted by the same reference numerals, and redundant description is omitted.
< embodiment 1 >
Fig. 1 is a schematic cross-sectional view showing a surface emitting structure 1 according to embodiment 1 of the present invention. As shown in fig. 1, the surface light emitting structure of the present invention includes: a 1 st light guide layer 10 and a 2 nd light guide layer 20 arranged in a stacked manner; a light shielding layer 30 disposed between the 1 st light guide layer 10 and the 2 nd light guide layer 20; a 1 st light emitting assembly 40 mounted on at least one side of the 1 st light guide layer 10; and a 2 nd light emitting module 50 mounted on at least one side surface of the 2 nd light guide layer 20 and located on a different side surface from the 1 st light emitting module 40, wherein the 1 st light emitting module 40 and the 2 nd light emitting module 50 generate different lights, the light generated by the 1 st light emitting module 40 is irradiated to one side of the surface light emitting structure 1 through the 1 st light guide layer 10, the light generated by the 2 nd light emitting module 50 is irradiated to the other side of the surface light emitting structure 1 through the 2 nd light guide layer 20, and the light shielding layer 30 shields a light path between the 1 st light emitting module 40 and the 2 nd light emitting module 50. In this example, the 1 st light emitting device 40 generates illumination light, and the 2 nd light emitting device 50 generates sterilization light or fresh-keeping light. The sterilizing light is, for example, ultraviolet light, and the light for keeping vegetables and fruits fresh is, for example, cyan visible light (wavelength 500 to 460 nm). Of course, depending on the specific structure, the 2 nd light emitting device 50 may generate illumination light, and the 1 st light emitting device 40 may generate sterilization light or light for keeping vegetables and fruits fresh. With this configuration, effects such as illumination, sterilization, freshness preservation, and the like can be achieved at the same time.
Fig. 2 is a schematic perspective view showing a surface emitting structure 1 according to embodiment 1 of the present invention. As shown in fig. 2, 1 st light emitting module 40 is attached to side surface 101 of 1 st light guide layer 10, 2 nd light emitting module 50 is attached to side surface 203 of 2 nd light guide layer 20, and light shielding layer 30 extends to side surface 101 of 1 st light guide layer 10 and side surface 203 of 2 nd light guide layer 20. Thus, the light shielding layer 30 can effectively shield the light emitted from the 1 st and 2 nd light emitting elements, and prevent interference between different lights. In addition, fig. 2 shows only an example in which the 1 st and 2 nd light emitting modules 40 and 50 are disposed on one side surfaces 101 and 203 of the 1 st and 2 nd light guide layers 10 and 20, respectively, but the disposition positions of the 1 st and 2 nd light emitting modules 40 and 50 are not limited thereto, and may be disposed on any 1 or more side surfaces of the 1 st and 2 nd light guide layers 10 and 20. In this case, it is preferable that the light shielding layer 30 extends to the side of the 1 st light guide layer 10 where the 1 st light emitting device 40 is not disposed and the side of the 2 nd light guide layer 20 where the 2 nd light emitting device 50 is not disposed. With this structure, the light shielding layer 30 can further effectively shield the 1 st and 2 nd light emitting elements 40 and 50 from light emitted therefrom, thereby preventing interference between different lights.
The light-shielding layer 30 is, for example, a PET (polyethylene terephthalate) film, and is preferably white or silver. With this structure, the light-shielding layer 30 can be provided with a reflection effect, and interference between the light emitted from the 1 st and 2 nd light-emitting devices 40 and 50 can be more effectively prevented.
As shown in fig. 1, the surface light emitting structure 1 further includes a U-shaped frame 60 that covers the 1 st light guide layer and the 2 nd light guide layer, and the 1 st and 2 nd light emitting elements 40 and 50 are disposed in the grooves of the U-shaped frame 60. With this configuration, it is possible to prevent light emitted from the 1 st and 2 nd light emitting modules 40 and 50 from being emitted to the outside, and to make the surface light emitting structure 1 more beautiful. Furthermore, the inner surface of the U-shaped frame 60 preferably has a light reflecting effect, whereby the light emitted by the 1 st and 2 nd light emitting assemblies 40, 50 can be better guided to the 1 st and 2 nd light guiding layers 10, 20.
Fig. 3 is a schematic perspective view showing the side surfaces of light guide layers 10 and 20 provided with light emitting elements 40 and 50 in surface light emitting structure 1 according to embodiment 1 of the present invention. The side represented in fig. 3 may be, for example, the side 101, 203 in fig. 2. Fig. 4 is a schematic perspective view showing the side surfaces of light guide layers 10 and 20 in which light emitting elements 40 and 50 are not provided in surface emission structure 1 according to embodiment 2 of the present invention. The side surfaces shown in FIG. 4 can be, for example, the side surfaces 102 to 104, 201 to 202, 204 in FIG. 2. As is apparent from fig. 3 and 4, the edges of the 1 st light guide layer 10 and the 2 nd light guide layer 20 preferably have chamfers, the length of the right-angled side of the chamfer of the side surface 101 on which the 1 st light emitting element 40 is disposed is shorter than the length of the right-angled side of the chamfer of the side surfaces 102 to 104 on which the 1 st light emitting element 40 is not disposed in the 1 st light guide layer 10, and the length of the right-angled side of the chamfer of the side surface 203 on which the 2 nd light emitting element 50 is disposed is shorter than the length of the right-angled side of the chamfer of the side surfaces 201 to 202 and 204 on which the 2 nd light emitting element 50 is not disposed in the 2 nd light guide. According to the structure, light can more easily enter the light guide layers 10 and 20 at the side surfaces 101 and 203 with short lengths of the right-angle sides of the chamfer, and the side surfaces 102 to 104, 201 to 202 and 204 with long lengths of the right-angle sides of the chamfer can form reflecting surfaces to reflect the light L at the chamfer, so that the light L can be reduced from being emitted from the side surfaces without attaching a reflecting film.
In addition, in the 1 st light guide layer 10, the length of the right-angled side of the chamfer of the side surface 101 where the 1 st light emitting assembly 40 is arranged is less than one fourth of the thickness of the 1 st light guide layer 10, and the length of the right-angled side of the chamfer of the side surface 102-104 where the 1 st light emitting assembly 40 is not arranged is greater than one fourth of the thickness of the 1 st light guide layer 10; in the 2 nd light guide layer 20, the length of the right-angled side of the chamfer of the side surface 203 where the 2 nd light emitting element 50 is arranged is less than one fourth of the thickness of the 2 nd light guide layer 20, and the length of the right-angled side of the chamfer of the side surfaces 201 to 202, 204 where the 2 nd light emitting element 50 is not arranged is greater than one fourth of the thickness of the 2 nd light guide layer 20. By the length of the right-angled side of the chamfer being less than a quarter of the thickness, it is ensured that the maximum amount of light from the light emitting component 40, 50 enters the conductor layer 10, 20. Conversely, by chamfering the cathetus length more than a quarter of the thickness, light L can be reduced from leaking out of the edges of the conductor layers 10, 20.
In the surface light emitting structure 1 of the present embodiment, it is preferable to use a homogeneous glass product or a homogeneous transparent organic material having a light transmittance of 85% or more for the 1 st light guide layer 10 and the 2 nd light guide layer 20. With this configuration, light can be efficiently guided.
In addition, in the surface light emitting structure 1 of the present embodiment, if the total length of the 1 st and 2 nd light emitting elements 40 and 50 exceeds a predetermined length (for example, 50cm), if the 1 st and 2 nd light emitting elements 40 and 50 are provided on one side surface of the 1 st and 2 nd light guide layers 10 and 20 as shown in fig. 2, the light on the one side surface may be too strong, and the light irradiation may be uneven. Therefore, in this case, it is preferable to mount the 1 st light emitting element 40 on the two opposite side surfaces of the 1 st light guide layer 10 (side surfaces 101 and 103, or side surfaces 102 and 104), and it is also possible to mount the 2 nd light emitting element 50 on the two opposite side surfaces of the 2 nd light guide layer 20 (side surfaces 202 and 204, or side surfaces 201 and 203). According to such a structure, the illumination effect can be enhanced and the unevenness of the light emission effect can be avoided.
In order to provide the surface emitting structure 1 of the present embodiment with the multi-color light emitting effect, it is preferable that the three primary color LED light sources of red, yellow, and blue constituting the 1 st light emitting element 40 are respectively mounted on three side surfaces (for example, side surfaces 101 to 103) of the 1 st light guide layer 10. With this configuration, the surface emission effect of different colors can be achieved by various combinations of turning on and off the three primary color LED light sources of red, yellow, and blue.
In the surface emitting structure 1 of the present embodiment, the 1 st light emitting element 40 and the 2 nd light emitting element 50 are preferably LED light source substrates. The LED light source substrate may be, for example, a long strip, and may be one or a plurality of strips. The LED substrate light source is preferably packaged by transparent silica gel or a high-light-transmission plastic sleeve. According to the structure, the insulation effect can be ensured.

The refrigerator 100 includes the surface light emitting structure of embodiment 1. With this configuration, effects such as illumination, sterilization, freshness preservation, and the like can be achieved at the same time.
As shown in fig. 5, in refrigerator 100 according to embodiment 2 of the present invention, surface light emitting structure 1 is preferably attached to an upper portion of vegetable box 2, and light generated by second light emitting unit 50 is preferably irradiated into vegetable box 2. With this structure, the surface light emitting structure 1 can be provided at an appropriate position, and the sterilization or freshness preservation of the items in the vegetable and fruit box 2 can be ensured. Figure 5 shows the box 2 in a lower part of the cooling compartment. However, when the fruit and vegetable box 2 is located at the middle or upper portion of the refrigerating chamber, the surface emitting structure 1 may be provided at the lower portion of the fruit and vegetable box 2, and the light generated by the 2 nd light emitting element 50 may be irradiated into the fruit and vegetable box 2, thereby obtaining the same effect.
As shown in fig. 6, the surface light emitting structure 1 may be installed in the freezing chamber or the temperature changing chamber, and may be installed above a space in which an uncooked food (e.g., ice cream, ice cubes, etc.) is placed, that is, above the pockets 3 and 4. According to the structure, the uncooked food in the freezing chamber or the temperature changing chamber can be effectively sterilized or preserved.
