Description

Technical Field

[0001] This utility model relates to the technical field of light-emitting panels, and in particular to a multi-layer light-emitting panel structure. Background Technology

[0002] Light-emitting panels, especially LED light-emitting panels, are widely used due to their superior performance.

[0003] Extensive searching revealed Chinese Patent Publication No. CN203533338U, which discloses a direct-emitting LED panel light, relating to the field of lighting devices. This direct-emitting LED panel light includes a backplate, a PCB circuit board, reflective paper, an aluminum frame, aluminum frame splicing screws, a diffuser plate, an external power supply, and connecting wires connecting the backplate and the external power supply. At least one LED emitter is soldered onto the PCB circuit board and electrically connected to it. An optical lens is correspondingly disposed on the surface of each LED emitter. A layer of perforated reflective paper is disposed on the surface of the PCB circuit board, and the optical lens is embedded in the perforations of the reflective paper. The reflective paper on the PCB circuit board and the optical lens on the surface of the LED emitter enable the direct-emitting LED panel light to emit uniform light, high brightness, no glare, and a wide illumination angle, achieving a more comfortable lighting effect for the user.

[0004] In summary, existing light-emitting panels, with their multi-layered components laid flat from top to bottom within the frame, result in poor independence between the light-emitting unit and the light-guiding unit, making it inconvenient to disassemble and install them separately.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a multi-layer light-emitting panel structure that would have greater industrial application value. Utility Model Content

[0006] To solve any of the above-mentioned technical problems, the purpose of this utility model is to provide a multi-layer light-emitting panel structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A lower mounting cavity is provided on the top inner side of the lower housing, a base is installed in the lower mounting cavity, and a light-emitting plate is installed on the base;

[0010] An upper first mounting cavity is provided on the bottom inner side of the upper cover, and a light guide plate is installed in the upper first mounting cavity. An upper second mounting cavity is provided on the top inner side of the upper cover, and a through hole is provided between the upper first mounting cavity and the upper second mounting cavity. A transparent light-emitting cover is installed in the upper second mounting cavity.

[0011] As a further improvement of this utility model, a lower splicing groove is provided on the top left and right sides of the lower shell, and an upper splicing protrusion is provided on the bottom of the upper cover directly above the lower splicing groove, with the upper splicing protrusion embedded into the lower splicing groove from top to bottom.

[0012] As a further improvement of this utility model, the upper splicing protrusion is embedded into the lower splicing groove below and then locked by the bolt on the outside.

[0013] As a further improvement of this utility model, an isolation layer is provided between the light-emitting plate and the substrate.

[0014] As a further improvement of this utility model, a light-transmitting film is bonded to the outside of the light-emitting cover.

[0015] As a further improvement of this utility model, the light-emitting cover is a curved screen or a straight screen.

[0016] As a further improvement of this utility model, a number of heat dissipation holes are evenly provided on the lower shell below the base.

[0017] As a further improvement of this utility model, a filter screen is installed on the lower housing inside or outside the heat dissipation holes.

[0018] By means of the above solution, this utility model has at least the following advantages:

[0019] This utility model, through the structural arrangement of the lower mounting unit and the upper mounting unit, facilitates the separate design of the light-emitting unit with the light-emitting plate as the main body and the light-guiding unit with the light guide plate as the main body, and makes it easy to disassemble and install the two parts separately.

[0020] This invention, by setting an isolation layer on the substrate before installing the light-emitting panel, can improve the flatness of the substrate surface and reduce the chance of the light-emitting panel not being installed properly.

[0033] Example

[0034] like Figures 1-4 As shown,

[0035] A multi-layer light-emitting panel structure includes a lower mounting unit 1 and an upper mounting unit 2 from bottom to top, wherein the lower mounting unit 1 and the upper mounting unit 2 are spliced ​​together from bottom to top.

[0036] 1. The lower mounting unit 1 includes a lower housing 11, a base 13 and a light-emitting plate 15, and the upper mounting unit 2 includes an upper cover 21 and a light guide plate 23.

[0037] An upper first mounting cavity 22 is provided on the inner side of the bottom of the upper cover 21. A light guide plate 23 is installed in the upper first mounting cavity 22. An upper second mounting cavity 25 is provided on the inner side of the top of the upper cover 21.

[0038] The light-emitting cover 26 is a curved screen or a straight screen, and a light-transmitting film is bonded to the outside of the light-emitting cover 26.

[0039] In addition, the inner side of the light guide plate 23 is designed with a frosted surface. The light emitted by the light-emitting plate 15 can be refracted or diffused through the frosted surface, and the light can be further delivered to various positions in the light guide plate, so that the entire panel emits light evenly and softly.

[0040] 2. A lower mounting cavity 12 is provided on the inner side of the top of the lower housing 11. A base 13 is installed in the lower mounting cavity 12, and a light-emitting plate 15 is installed on the base 13.

[0041] An insulating layer 14 is provided between the light-emitting plate 15 and the substrate 13. If the light-emitting plate 15 is directly mounted on the substrate 13, the light-emitting plate 15 may not be properly mounted due to unevenness in some areas of the substrate 13, resulting in quality problems. Therefore, the insulating layer 14 (dielectric material) is pre-printed on the substrate 13 to improve the flatness of the upper surface of the substrate 13 and improve the yield.

[0042] 3. The splicing and positioning structure of the lower shell 11 and the upper cover 21:

[0043] The lower housing 11 has a recessed lower splicing groove 16 on the top left and right sides. The upper cover 21, which is directly above the lower splicing groove 16, has a protruding upper splicing protrusion 24 on the bottom. The upper splicing protrusion 24 is embedded into the lower splicing groove 16 from top to bottom.

[0044] The upper splicing protrusion 24 is embedded into the lower splicing groove 16 below and then locked by the bolt on the outside.

[0045] 4. Several heat dissipation holes are evenly provided on the lower housing 11 below the base 13, and a filter screen is installed on the lower housing 11 inside or outside the heat dissipation holes.
