[0001] This utility model relates to the field of lighting technology, and in particular to a double-sided light-emitting lamp. Background Technology

[0002] Currently, in many places, such as homes, double-sided light fixtures are often needed to achieve double-sided illumination.

[0003] Some existing larger light boxes have a back panel installed inside the box, and then dot-matrix LED light strips are installed on both sides of the back panel to achieve double-sided illumination. However, using dot-matrix LED light strips as the light source requires a large number of light strips, resulting in high energy consumption. Utility Model Content

[0004] The main purpose of this utility model is to propose a double-sided light-emitting lamp, which addresses the problem of high energy consumption in the existing method of installing dot matrix LED light strips on both sides of the back plate.

[0005] To achieve the above objectives, the double-sided light-emitting lamp proposed in this utility model includes:

[0006] A light guide plate having opposing first and second surfaces, the first surface having a plurality of first points and the second surface having a plurality of second points, the first points and the second points being staggered; and

[0007] A light-emitting element is disposed on the edge of the light guide plate and emits light towards the light guide plate.

[0008] In some embodiments, the light guide plate has a fixing groove for accommodating the light-emitting element.

[0009] In some embodiments, the number of light-emitting elements is at least two, the number of fixing slots is correspondingly set to at least two, the at least two fixing slots are arranged opposite to each other, and the light-emitting elements are housed in the fixing slots.

[0010] In some embodiments, the light-emitting element is attached to the wall of the fixing groove.

[0011] In some embodiments, the double-sided light-emitting lamp further includes a light-diffusing element disposed on the first and / or second side of the light guide plate.

[0012] In some embodiments, there are two light-diffusing elements, which are respectively disposed on the first and second surfaces of the light guide plate.

[0013] In some embodiments, at least two of the light-diffusing elements are respectively attached to the first and second surfaces of the light guide plate.

[0014] In some embodiments, the double-sided light-emitting lamp further includes a frame, the inner wall of which is provided with a groove, and the light guide plate is installed in the groove.

[0015] In some embodiments, the frame has two slots, and the clamping groove is located between the two slots; there are two light-diffusing elements, and each of the two light-diffusing elements has a protruding limiting protrusion. The limiting protrusion is engaged with the slot to fix the light-diffusing element to the frame; the light guide plate is located between the two light-diffusing elements.

[0016] In some embodiments, the light-emitting element is an LED light strip, and the light-diffusing element is a light-diffusing plate or a light-diffusing film.

[0017] The technical solution of this utility model involves setting multiple first points and multiple second points on opposite first and second surfaces of a light guide plate, with the first and second points offset from each other. Then, a light-emitting element is placed along the edge of the light guide plate, emitting light towards the light guide plate, so that the light is refracted through the first and second points within the light guide plate, thereby enabling the light guide plate to emit light from both sides. Since only the light-emitting element needs to be placed along the edge of the light guide plate to achieve double-sided light emission, the number of light-emitting elements used is small, reducing energy consumption.

[0035] Currently, in many places, such as homes, double-sided light fixtures are often needed to achieve double-sided illumination.

[0036] Some existing larger light boxes have a back panel installed inside the box, and then dot-matrix LED light strips are installed on both sides of the back panel to achieve double-sided illumination. However, using dot-matrix LED light strips as the light source requires a large number of light strips, resulting in high energy consumption.

[0037] This utility model proposes a double-sided light-emitting lamp 100. Please refer to [link / reference]. Figure 2 , Figure 5 and Figure 6 The double-sided light-emitting lamp 100 proposed in this utility model includes:

[0038] Light guide plate 10, having a first surface 11 and a second surface 12 opposite to each other; the first surface 11 has a plurality of first points 110, and the second surface 12 has a plurality of second points 120; the first points 110 and the second points 120 are staggered.

[0039] The light-emitting element 20 is disposed on the edge of the light guide plate 10 and emits light towards the light guide plate 10.

[0040] Specifically, the light guide plate 10 adopts a cross-dotting method from top to bottom, and the light-emitting element 20 emits light towards the light guide plate 10 to achieve double-sided light emission of the light guide plate 10, which improves the light emission efficiency and ensures the consistency of light emission from top to bottom of the light guide plate 10.

[0041] In this design, the light-emitting element 20 emits light, and some of the light is directly refracted within the light guide plate 10 and transmitted to either the first point 110 or the second point 120 to form a bright spot. Please refer to [link / reference]. Figures 3 to 5Multiple first points 110 and multiple second points 120 are arranged in the reflection path of the reflected light to reflect the light to the next hole, thereby causing the light to be reflected from one side of the light guide plate 10 to the other side. Moreover, the light is refracted at each first point 110 and each second point 120 so that the light guide plate 10 emits light from both sides.

[0042] The technical solution of this utility model involves setting multiple first points 110 and multiple second points 120 on the opposing first surface 11 and second surface 12 of the light guide plate 10, with the first points 110 and second points 120 being staggered. Then, a light-emitting element 20 is placed along the edge of the light guide plate 10, emitting light towards the light guide plate 10, so that the light is refracted through the first points 110 and second points 120 within the light guide plate 10, thereby enabling the light guide plate 10 to emit light from both sides. Since only the light-emitting element 20 needs to be placed along the edge of the light guide plate 10 to achieve double-sided light emission, the number of light-emitting elements 20 used is small, reducing energy consumption.

[0043] The light-emitting element 20 can be installed only on the upper and lower sides of the light guide plate 10. Alternatively, the light-emitting element 20 can be installed only on the left and right sides of the light guide plate 10.

[0044] Light-emitting elements 20 can also be installed around the light guide. Since the light guide plate 10 adopts a double-sided dotted pattern, when the light-emitting elements 20 emit light towards the light guide plate 10, the entire light guide plate 10 emits light. The light guide plate 10 can also be used as a shelf for placing items.

[0045] The number of light-emitting elements 20 required by this invention is less than the number of dot matrix light strips required by existing light boxes, thus reducing energy consumption and lowering the cost of use.

[0046] Please refer to Figure 5 and Figure 6 The light guide plate 10 has a fixing groove 13 for accommodating the light-emitting element 20. With this configuration, the light-emitting element 20 can be installed inside the light guide plate 10 without the need for a separate locking structure, simplifying the structure of the light guide plate 10. Furthermore, the light-emitting element 20, housed within the light guide plate 10, is less susceptible to damage from external objects.

[0047] Please see Figure 2 The number of light-emitting elements 20 is at least two, and the number of fixing slots 13 is correspondingly set to at least two. The at least two fixing slots 13 are arranged opposite to each other, and the light-emitting elements 20 are housed in the fixing slots 13.

[0048] Optionally, the light guide plate 10 is provided with fixing grooves 13 on all four sides so that the light-emitting element 20 can be installed on two of the sides of the light guide plate 10.

[0049] To ensure that the light-emitting component 20 does not fall off within the light guide plate 10, the light-emitting component 20 is adhered to the wall of the fixing groove 13 for easy installation. The light-emitting component 20 can be a flexible LED light strip, and the light guide plate 10 is made of PMMA board.

[0050] Furthermore, the double-sided light-emitting lamp 100 also includes a light-diffusing element 30, which is disposed on the first surface 11 and / or the second surface 12 of the light guide plate 10.

[0051] Both the first surface 11 and the second surface 12 of the light guide plate 10 can be equipped with light homogenizers 30. The light transmitted from the light guide plate 10 is uniformly emitted through the light homogenizer, so as to eliminate light spots and improve the uniformity of light distribution.

[0052] Please see Figure 2 The light-diffusing element 30 is two in number, and the two light-diffusing elements 30 are respectively disposed on the first surface 11 and the second surface 12 of the light guide plate 10. In one embodiment, please refer to... Figure 1 and Figure 2 Two light-diffusing components 30 are respectively attached to the first surface 11 and the second surface 12 of the light guide plate 10.

[0053] To facilitate the installation of the light-diffusing components 30, at least two light-diffusing components 30 are respectively attached to the first surface 11 and the second surface 12 of the light guide plate 10. Specifically, the two light-diffusing components 30 can be attached to the first surface 11 and the second surface 12 of the light guide plate 10 using adhesive tape. The light-diffusing component 30 is a light-diffusing plate. The light-diffusing plate and the light guide plate 10 can be bonded and fixed together using double-sided adhesive tape. The sides of both the light-diffusing plate and the light guide plate 10 can be edged with reflective tape, using a four-sided edge-wrapping process. This not only reduces the impact on the light output of the light guide plate 10 but also achieves a frameless effect. Optionally, the thickness of the light-diffusing plate can be set to 8mm, and the light-diffusing plate can be made of double-sided frosted acrylic sheet. A composite light-diffusing film can be attached to the side of the light-diffusing plate facing away from the light guide plate 10 to protect the light-diffusing plate. The thickness of the light guide plate 10 can be set to 6mm.

[0054] In another embodiment, the double-sided light-emitting lamp 100 further includes a frame 40, the inner wall of which is provided with a groove 41, and the light guide plate 10 is installed in the groove 41.

[0055] The double-sided light-emitting lamp 100 is a light box. The frame 40 is used to fix the light guide plate 10. Since the light-emitting component of the double-sided light-emitting lamp 100 of this utility model only requires a light guide plate 10 and a light-emitting element 20 installed on the light guide plate 10, and the light-emitting element 20 does not need to be fixed by a back plate, the weight of the double-sided light-emitting lamp 100 is reduced, and the product cost is lowered.

[0056] Optionally, the frame 40 is made of aluminum alloy. The four corners of the frame 40 are spliced ​​together using L-shaped fixing feet. When splicing, the light guide plate 10 can be inserted into the groove 41 in the middle of the aluminum material to fix the light guide plate 10.

[0057] Please see Figures 8 to 10 The frame 40 is provided with two slots 42, and the clamping groove 41 is located between the two slots 42; there are two light-diffusing elements 30, and each of the two light-diffusing elements 30 is provided with a limiting protrusion 31. The limiting protrusion 31 is inserted into the slot 42 to fix the light-diffusing element 30 to the frame 40; the light guide plate 10 is located between the two light-diffusing elements 30.

[0058] In another embodiment, please refer to Figure 7 and Figure 8 The light-diffusing element 30 can be a light-diffusing film. The two light-diffusing films are fixed to the frame 40 by limiting protrusions 31, so that the two light-diffusing films are fixed on both sides of the light guide plate 10.

[0059] Among them, the limiting protrusion 31 is a silicone strip. The perimeter of the light-diffusing film is attached with silicone strips, which are snapped into the slots 42 of the frame 40. The light-diffusing film is fixed to the frame 40 by the silicone strips and is located on the first surface 11 or the second surface 12 of the light guide plate 10.

[0060] In one embodiment, the light-emitting element 20 is a flexible LED light strip, and the light-diffusing element 30 is a light-diffusing plate. In another embodiment, the light-emitting element 20 is a flexible LED light strip, and the light-diffusing element 30 is a light-diffusing film.

[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
