Abstract
Description
Technical Field
[0001] This utility model relates to the field of display panel technology, and in particular to an intelligent light-emitting structure for high-temperature cooking equipment. Background Technology
[0002] With the development of display technology, liquid crystal (LC) displays and light-emitting diode (LED) displays have gradually become the two mainstream displays in the display field.
[0003] Currently, existing display modules typically consist of a surrounding support frame, and within the frame, arranged sequentially from bottom to top, a metal backplate, LED chips, a diffuser plate, a quantum dot film, a diffuser film, a prism sheet, and a light-emitting panel. The overall structure of the display module is relatively complex. Due to the reflection of light by numerous optical components (such as diffuser plates, quantum dot films, diffuser films, and prism sheets), the light travels through the display module for a long time and consumes a significant amount of light during propagation. Therefore, a large number of LED chips are placed on the metal backplate, increasing the overall manufacturing cost of the display module and hindering mass production. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent light-emitting structure for high-temperature cooking equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A smart light-emitting structure for a high-temperature cooking device includes a bracket, a first light guide plate, a second light guide plate, a PCB circuit board, side-emitting LED beads, and a color film sticker. The bracket has a limiting groove at its bottom, within which a connecting post is located. The PCB circuit board is disposed within the limiting groove and fixedly connected to the connecting post. The bracket has a first limiting groove and a second limiting groove at its top. The first light guide plate is engaged in the first limiting groove and fixedly connected to the PCB circuit board at its bottom. The second light guide plate is engaged in the second limiting groove and fixedly connected to the PCB circuit board at its bottom. The side-emitting LED beads are fixedly connected to the PCB circuit board and disposed on the sides of the first and second light guide plates. The color film sticker is adhered to the first and second light guide plates.
[0007] Compared with existing technologies, the intelligent light-emitting structure of the high-temperature cooking device proposed in this application has the following beneficial effects:
[0008] In practical applications, by evenly arranging the side-emitting LED beads on the sides of the first and second light guide plates, the light source emitted by the LED beads can be refracted by prisms on the sides of the light guide plates to illuminate them. This arrangement reduces the number of LED beads required, reduces the cost of LED bead arrangement, and facilitates the assembly of the display module. The simplified internal layout of the display module allows the touch components to be transferred from the color film surface to the PCB circuit board, and only copper wires need to be arranged on the PCB circuit board to achieve the touch effect using the light guide plate as a medium.
[0009] Preferably, a light guide hole is formed on the first light guide plate, and the side-emitting lamp bead is disposed in the light guide hole.
[0010] Beneficial effect: By opening light guide holes inside the first light guide plate, the LED beads can be arranged on the inner side wall of the light guide plate, thereby improving the brightness of the first light guide plate.
[0011] Preferably, a connecting groove is provided in the first limiting groove, and a connecting protrusion is provided on the first light guide plate, wherein the connecting protrusion is inserted into the connecting groove.
[0012] Beneficial effect: By connecting the protrusion and the groove, the first light guide plate is firmly connected and not easy to fall off when installed in the first limiting groove.
[0013] Preferably, a fixing groove is provided in the second limiting groove, and a fixing protrusion is provided on the second light guide plate, wherein the fixing protrusion is inserted into the fixing groove.
[0014] Beneficial effect: The second light guide plate is more firmly installed in the second limiting groove by the connection between the fixing protrusion and the fixing groove, and it is not easy to shake.
[0015] Preferably, the bottom of the first light guide plate and the second light guide plate are provided with protrusions.
[0016] Preferably, the protrusions are sparsely arranged on the side closer to the side-emitting LED, and densely arranged on the side farther from the side-emitting LED.
[0017] Beneficial effect: By setting a gradient array of convex dots on the light guide plate, with sparse arrangement on the side closer to the light source and dense arrangement on the side farther away from the light source, the overall brightness of the light guide plate when illuminated by the light source is consistent.
[0018] Preferably, a reflective film is also provided, which is attached to the bottom of the first light guide plate and the second light guide plate.
[0019] Beneficial effect: By attaching reflective film to the bottom of the first and second light guide plates, the light source is reflected upward when refracted inside the light guide plates, preventing the diffusion of the light source at the bottom of the light guide plates.

[0026] The reference numerals in the accompanying drawings include: bracket 1, first light guide plate 2, second light guide plate 3, PCB circuit board 4, side-emitting LED bead 5, color film surface sticker 6, limiting groove 7, connecting post 8, first limiting groove 9, second limiting groove 10, light guide hole 11, connecting groove 12, connecting protrusion 13, fixing groove 14, fixing protrusion 15, protrusion 16, reflective film 17.
[0027] As attached Figure 1-5 As shown: This embodiment demonstrates an intelligent light-emitting structure for a high-temperature cooking device, including a bracket 1, a first light guide plate 2, a second light guide plate 3, a PCB circuit board 4, side-emitting LED beads 5, and a color film sticker 6. A limiting groove 7 is formed at the bottom of the bracket 1, and a connecting post 8 is provided in the limiting groove 7. The PCB circuit board 4 is set in the limiting groove 7 and fixedly connected to the connecting post 8. A first limiting groove 9 and a second limiting groove 10 are formed at the top of the bracket 1. The first light guide plate 2 is snapped into the first limiting groove 9 and fixedly connected to the PCB circuit board 4 at its bottom. The second light guide plate 3 is snapped into the second limiting groove 10 and fixedly connected to the PCB circuit board 4 at its bottom. The side-emitting LED beads 5 are fixedly connected to the PCB circuit board 4 and are set on the side of the first light guide plate 2 and the second light guide plate 3. The color film sticker 6 is attached to the first light guide plate 2 and the second light guide plate 3.
[0028] Specifically, by changing the arrangement of the side-emitting LED beads 5 and placing them on the sides of the first light guide plate 2 and the second light guide plate 3, the light source of the side-emitting LED beads 5 will shine into the interior of the light guide plate through the side of the light guide plate to achieve the effect of prism refraction. At the bottom of the light guide plate, there are also raised dots 16 arranged in a gradient array to achieve overall illumination of the first light guide plate 2 and the second light guide plate 3. Compared with the previous design, the number of LED beads 5 is reduced, and the cost of the display module is reduced.
[0029] In this embodiment, a light guide hole 11 is provided on the first light guide plate 2, and the side-emitting lamp beads 5 are disposed in the light guide hole 11.
[0030] Specifically, the first light guide plate 2 has a larger area than the second light guide plate 3, so a light guide hole 11 is opened in the middle to achieve the effect of the side-emitting lamp beads 5 illuminating the entire first light guide plate 2.
[0031] In this embodiment, a connecting groove 12 is provided in the first limiting groove 9, and a connecting protrusion 13 is provided on the first light guide plate 2. The connecting protrusion 13 is inserted into the connecting groove 12.
[0032] In this embodiment, a fixing groove 14 is provided in the second limiting groove 10, and a fixing protrusion 15 is provided on the second light guide plate 3. The fixing protrusion 15 is inserted into the fixing groove 14.
[0033] Specifically, by connecting the protrusion 13 to the connecting groove 12 and fixing the protrusion 15 to the fixing groove 14, the first light guide plate 2 and the second light guide plate 3 are more firmly connected to the bracket 1 and are less likely to loosen, thus ensuring the stability of the light source during refraction.
[0034] In this embodiment, the bottom of the first light guide plate 2 and the second light guide plate 3 are provided with protrusions 16.
[0035] In this embodiment, the protrusions 16 are sparsely arranged on the side closer to the side-emitting LED 5, and densely arranged on the side farther away from the side-emitting LED 5.
[0036] Specifically, by arranging the protrusions 16 on the light guide plate in a gradient array, with the protrusions sparsely arranged on the side closer to the side-emitting LED beads 5 and densely arranged on the side farther away from the side-emitting LED beads 5, the overall brightness of the light guide plate is made uniform when the light source illuminates it.
[0037] This embodiment also includes a reflective film 17, which is attached to the bottom of the first light guide plate 2 and the second light guide plate 3.
[0038] Specifically, the reflective film 17 is attached to the bottom of the first light guide plate 2 and the second light guide plate 3 to prevent the light source from scattering from the bottom of the light guide plate and improve the lighting effect of the front of the light guide plate.
