Description

Technical Field

[0001] This utility model relates to the field of interactive light technology, specifically to an interactive light structure that prevents light leakage. Background Technology

[0002] Interactive lights are a core component of intelligent vehicles, enabling real-time communication between people and vehicles, between vehicles themselves, and with the environment through dynamic lighting, thereby enhancing safety and personalized experiences. Existing interactive light anti-light-crossing structures include... Figure 1-2 As shown, it includes LED beads, an anti-light-crossing bracket, and an inner cover. The inner cover is made of dual-color injection molding and includes a plastic frame and a light-diffusing frame. However, due to the dual-color injection molding process, the light-emitting areas on the light-diffusing frame will still remain connected, making it impossible to completely avoid light cross-contamination. In addition, due to the influence of the dual-color injection molding process, the thickness of the light-diffusing frame is limited, so more space is needed to increase the distance between the LED beads and the light-diffusing frame. Therefore, an anti-light-cross-contamination interactive lamp structure was specially designed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an interactive lamp structure that prevents light leakage, thereby solving the aforementioned technical problems.

[0004] This utility model provides the following technical solution:

[0005] An interactive lamp structure for preventing light leakage includes a rear shell and an outer cover that are fixedly connected to each other. A cavity is provided between the rear shell and the outer cover. A lamp board and lamp beads evenly distributed on the lamp board are arranged along the cavity. The outer cover also has a light-transmitting element for light to pass through. The structure further includes a light-diffusing sheet arranged along the emission direction of the light from the lamp beads. Each group of lamp beads is also provided with an anti-light leakage structure. The light-diffusing sheet includes a light-diffusing element that is separately embedded in the light outlet of the anti-light leakage structure, so that the light emitted by each lamp bead illuminates the light-diffusing element that is separately arranged on the front side.

[0006] Furthermore, the anti-light-spreading structure is a metal component, which includes a mask. The mask has a second through hole for light to pass through, and the light-diffusing component is used to block the light outlet of the second through hole.

[0007] Furthermore, the light-diffusing sheet is formed from a sheet material.

[0008] Furthermore, the light-diffusing sheet is cut into the light-diffusing component using a die.

[0009] Furthermore, a fixing structure is provided between the mask and the light-diffusing component.

[0010] Furthermore, the fixing structure includes an anti-reverse buckle integrally disposed at the light outlet of the mask, and a step is provided at one end of the light-diffusing component near the light outlet. The anti-reverse buckle is an inwardly curved metal spring piece used to fix and lock the step.

[0011] Furthermore, the fixing structure is an adhesive sticker bonded to the light-diffusing component.

[0012] Furthermore, the mask has an integrally formed solder pad at one end near the lamp board, and the solder pad is fixed to the lamp board by SMT soldering.

[0013] Furthermore, the mask has a snap-fit ​​foot at one end near the lamp panel, and the inner side of the lamp panel has a hole for the snap-fit ​​foot.

[0014] Furthermore, the end of the buckle foot also has an arc-shaped protrusion, and the other end has a limiting member. The width of the arc-shaped protrusion and the limiting member are both greater than the width of the hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, by setting an anti-light-spreading structure, the mask in the anti-light-spreading structure wraps around the outside of the lamp bead, and a light-diffusing element of a similar size is set separately at the light outlet of the mask to receive the light emitted from the lamp bead and illuminate it evenly. The light-emitting areas of the light-diffusing sheet are not connected to each other, which can achieve a better anti-light-spreading effect.

[0017] 2. In this utility model, the light-diffusing sheet is molded, which can increase its thickness without being restricted by the two-color injection molding process, reduce the distance between the lamp beads and the light-diffusing sheet, and reduce the space requirements.

[0018] 3. In this utility model, by fixing the lamp board and the anti-light-spreading structure together, and fixing the anti-light-spreading structure and the light-diffusing component together, the light can be accurately irradiated from the lamp beads to the light-diffusing sheet, and then irradiated out through the light-transmitting component of the outer cover, thereby improving the positioning accuracy.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-2 The diagram shows a prior art design, which includes a rear shell 200 and an outer cover 600. The outer cover 600 also has a light-transmitting element 610. A cavity is formed between the rear shell 200 and the outer cover 600. A light-emitting element for emitting light is fixedly installed in the cavity. The light-emitting element includes a lamp plate 300 and multiple sets of LED beads 310 evenly distributed on the lamp plate 300. An inner cover surface 500 is provided for uniform light emission in the direction of the light emitted by the LED beads 310. Figure 2 As shown, the inner cover 500 includes a two-color injection molded plastic part 501 and a light-diffusing frame 502. An anti-light-spreading bracket 400 is provided between the LED bead 310 and the inner cover 500. The anti-light-spreading bracket 400 has a first through hole 401, allowing the light from the LED bead 310 to shine through the first through hole 401 onto the front light-diffusing frame 502. However, as... Figure 2Due to the injection molding process required, the light-emitting areas of the light-diffusing frame 502 shown are still connected, making it impossible to completely prevent light leakage. Furthermore, the inner cover 500 is made by two-color injection molding. In two-color injection molding, if the thickness exceeds 3mm, the injection pressure holding and cooling time will increase significantly, affecting production efficiency. As a result, only a thickness of 2.5-3.0mm can be achieved. In order to ensure uniform lighting, the distance between the LED and the light-diffusing sheet must be at least 30mm, requiring a large space. In addition, the light outlet of the light-transmitting component 610 on the outer cover 600 needs to be aligned with the light outlet of the inner cover 500 and the light outlet of the anti-light leakage bracket 400, which requires high positioning accuracy and high product deformation control.

[0031] Example 1: As Figure 3-7 As shown, this utility model provides a technical solution: an interactive lamp structure for preventing light crosstalk, including a light-diffusing sheet 700 arranged in the direction of light emission from the lamp beads 310, and an anti-light crosstalk structure 100 arranged around the lamp beads 310. The light-diffusing sheet 700 includes a light-diffusing element 710 that can be individually fitted into the light outlet of the anti-light crosstalk structure 100, so that there is no light crosstalk problem between the light emitted by each lamp bead 310. The light emitted by each lamp bead 310 illuminates the light-diffusing element 710 arranged separately on the front side, and the light-diffusing element 710 transmits the light evenly to the light-transmitting element 610 in the outer cover surface 600.

[0032] Among them, such as Figure 6 As shown, the anti-light-spreading structure 100 includes a mask 101. A second through hole 104 for light to pass through is provided in the mask 101. The front opening of the second through hole 104 is blocked by a light-diffusing element 710. A fixing structure is provided between the mask 101 and the light-diffusing element 710. In addition, the mask 101 and the lamp board 300 are fixedly connected by welding at the contact point.

[0033] Furthermore, such as Figure 5 As shown, the light-diffusing sheet 700 is cut by a die to form a light-diffusing component 710 adapted to the size of the opening on the front side of the second through hole 104. The light-diffusing component 710 can completely block the opening on the front side of the second through hole 104 to prevent light leakage and cross-contamination.

[0034] Furthermore, the light-diffusing sheet 700 is formed from a sheet metal, which can increase the thickness of the light-diffusing sheet 700 compared with the existing technology, thereby reducing the required spacing between the lamp bead 310 and the light-diffusing sheet 700.

[0035] Furthermore, such as Figure 6-7 As shown, the mask 101 is also integrally formed with a welding foot 102 at one end near the lamp plate 300, and the welding foot 102 is fixedly welded to the lamp plate 300.

[0036] Furthermore, SMT soldering technology can be used between solder pad 102 and lamp board 300.

[0037] Furthermore, the anti-light-shifting structure 100 is made of metal.

[0038] Furthermore, such as Figure 6-7 As shown, the fixing structure between the mask 101 and the light-diffusing element 710 includes a backstop 103. The light-diffusing element 710, which is assembled with the mask 101, has a step 711. During installation, the light-diffusing element 700 is pressed towards the front opening of the second through hole 104. Figure 6 and Figure 7 As shown, the anti-reverse buckle 103 is an inwardly curved metal spring with a certain arc. When the light-diffusing piece 710 is pressed against the mask 101, the metal piece at the end of the anti-reverse buckle 103 has a certain elasticity and can be locked on the sides of the step 711 to complete the fixed assembly, so that the light-diffusing piece 710 will not easily detach from the mask 101.

[0039] An adhesive sticker can also be applied to the light-diffusing element 710 to fix the light-diffusing element 710 and the mask 101 together.

[0040] Example 2: The difference from Examples 1 and 2 is that, as Figure 8-9 As shown, the face mask 101 has a snap-fit ​​foot 105. A set of holes 320 are provided on the lamp plate 300 for the snap-fit ​​foot 105 to pass through. The tail of the snap-fit ​​foot 105 also has an arc-shaped protrusion 106, and the other end has a limiting member 107. The width of the arc-shaped protrusion 106 and the limiting member 107 is greater than the width of the hole 320. During installation, since the snap-fit ​​foot 105 itself is a thin metal part with a certain degree of elasticity, after the snap-fit ​​foot 105 is inserted into the hole 320, the arc-shaped protrusion 106 and the limiting member 107 lock the inside and outside of the lamp plate 300, thereby fixing the face mask 101 on the lamp plate 300.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
