[0014] As mentioned above, with the market demand for light-emitting products tending to diversification, especially in the uniqueness of light-emitting effect and visual performance, the prior art has been difficult to meet the requirements of specific applications. Therefore, the inventors of the application propose a light-emitting module capable of realizing multiple inverted image display effect in a local pattern area, and through precise optical structure design, the display mode of the pattern is more special, so as to meet the market optical display demand. The specific technical features of the application will be described below through the drawings and the text. The structures, proportions, sizes, shapes or application states shown in the drawings are only schematic and are used to illustrate the technical features of the application, and are not intended to represent the actual structure design. It is hereby stated.

[0015] Please refer to Figure 1 which is an exploded structural schematic diagram of the light-emitting module of one embodiment of the application. The light-emitting module 1 disclosed by the application realizes multiple inverted image display effect in a local pattern area, and comprises a reflecting sheet 10, a first light guide plate 11, a semi-penetrating reflective lens sheet 12, a second light guide plate 13 and at least one LED light source 14.

[0016] The first light guide plate 11 is stacked on the reflecting sheet 10, and the lower surface of the first light guide plate 11 has a first dot structure 111. In the embodiment, the first dot structure 111 is distributed to form a plurality of radially arranged long strip areas, such as Figure 1 the area surrounded by the dashed line in the figure, wherein the dashed line is only schematic and is not intended to represent the actual line. The semi-penetrating reflective lens sheet 12 is stacked on the first light guide plate 11, and is used to realize the effect of partially penetrating and partially reflecting light. The semi-penetrating reflective lens sheet 12 comprises a base material 121 and at least one metal layer 122, and the metal layer 122 is plated on the upper surface and / or the lower surface of the base material 121. The metal layer 122 can be plated on the upper surface or the lower surface of the base material 121, or can be plated on both the upper surface and the lower surface of the base material 121. In the embodiment, the metal layer 122 is plated on the lower surface of the base material 121.

[0017] The second light guide plate 13 is stacked on the half-transmission reflection lens sheet 12, and the upper surface of the second light guide plate 13 has a second dot structure 131. In the above-mentioned stack structure, the interval between the first dot structure 111 provided on the lower surface of the first light guide plate 11 and the second dot structure 131 provided on the upper surface of the second light guide plate 13 is the total thickness of the first light guide plate 11, the half-transmission reflection lens sheet 12 and the second light guide plate 13, which can be used to form an effective back-and-forth reflection distance. In the present embodiment, the second dot structure 131 is distributed to form an oval region and a plurality of long strip regions arranged radially outward from the oval region, as shown in the dotted line box in Figure 1 The LED light source 14 is arranged on one side of the first light guide plate 11 and the second light guide plate 13 to provide side light, and in the present embodiment, a plurality of LED light sources 14 are arranged as an example.

[0018] Please continue to refer to Figure 2 which is a schematic diagram of the application of the light emitting module according to an embodiment of the present application. When the LED light source 14 is lit, the first dot structure 111 forms a first light emitting pattern A, and the second dot structure 131 forms a second light emitting pattern B, the second light emitting pattern B and the first light emitting pattern A are superimposed on each other, and the first light emitting pattern A region has a multiple reflection display effect. In the above-mentioned dot structure distribution example, the first light emitting pattern A is composed of a plurality of long strip regions, and the second light emitting pattern B is composed of an oval region and a plurality of long strip regions. That is, in the pattern example of the present embodiment, when a user views the light emitting module 1 with the LED light source 14 lit, the oval region will have a normal light emitting effect, and the long strip regions arranged radially around it will have a multiple reflection light emitting effect. Among them, Figure 2 The reflection is shown by dotted lines, but the number of reflections shown in the figure is only for illustration and does not represent the actual form.

[0019] Therefore, through the stack structure design of the light emitting module 1, when the pattern is displayed, the light emitting module 1 can present a local region with extended reflection effect in the same pattern, forming a multiple reflection visual performance, and the remaining region maintains a normal light emitting state. In other words, in the final display pattern, the region of the first light emitting pattern A will present a multiple reflection display effect, and further present a unique pattern performance.

[0020] Further, regarding the selection of the base material 121 of the semi-transmissive reflective lens sheet 12, materials such as PC (Polycarbonate), PET (Polyethylene Terephthalate), or PS (Polystyrene) can be used to ensure good optical application performance and good structural strength or flexibility to meet different application requirements.

[0021] The metal layer 122 can be made of silver or nickel to provide appropriate reflection effect and improve the manufacturing convenience.

[0022] The reflective sheet 10 can be a silver reflective sheet to provide high reflection function and greatly reduce light loss, thereby improving the light emitting efficiency.

[0023] In addition, the LED light source 14 in the light emitting module 1 for providing light can be arranged on a circuit substrate 15, and the circuit substrate 15 is stacked on part of the second light guide plate 13 to improve the assembly convenience. This configuration helps the alignment assembly of the components and ensures that the LED light source 14 is arranged corresponding to the side surface of the first light guide plate 11 and the second light guide plate 13, so that the first light guide plate 11 and the second light guide plate 13 effectively receive the side incident light, thereby forming the first light emitting pattern A and the second light emitting pattern B.

[0024] In summary, the light emitting module proposed in the present application can exhibit multiple inverted display effects in the local pattern area through the special design of the multi-layer optical structure. This design not only strengthens the level and three-dimensional effect of the light emitting pattern, but also can be flexibly applied to various electronic devices to meet the market demand for diversified optical performance. The present application also proposes many further additional technical features for the light emitting module, such as the material selection part, which can select the base material from PC, PET or PS, or use silver or nickel as the metal layer material, or use a silver reflective sheet as the reflective sheet, so as to have better optical effect performance and optimize the production convenience. In addition, in order to facilitate the assembly alignment and ensure the accuracy of the light source position, the LED light source can be arranged on the circuit substrate, and the circuit substrate can be stacked on part of the second light guide plate.
