It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concepts of the present invention.

As shown in FIG. 1 and FIG. 2 , the anti-cross-light structure includes a plurality of anti-cross-light structural members 2 and a light guide column 1 . The LED 4 in this embodiment is a three-pin two-color LED, and a plurality of LEDs are soldered on the printed board 3 through solder pins.

As shown in FIG. 1 to FIG. 2 , the LED 4 is welded on the printed board 3 through the solder fillet, and the anti-cross light structure 2 can be directly sleeved on the LED 4 to prevent the light of one LED from being irradiated to the other LED and guiding the light. On the light column; the light guide column 1 is installed on the anti-cross light structure 2 , and the head of the light guide column 1 is matched with the panel 5 .

The light guide column is used to transmit the light emitted by the LED to the corresponding position of the panel; the head of the light guide column 1 is installed with the panel 5 . The anti-light streak structure 2 is designed with a guiding and positioning structure, which can be easily installed on the LED and positioned during the installation process; 1 is fixed on the anti-cross light structural member 2.

The guiding and positioning structure of the anti-string light structure member 2 is designed as a step shape of a large circle and a small circle. The bottom of the large circle can also be used to cooperate with the printed board 3 to play a positioning role. As shown in Figure 2, the anti-string The bottom of the light structure part 2 is designed as a step shape with a large circle and a small circle. The inner diameter of the large circle is larger than the diameter of the base of the LED, and the diameter of the small circle is larger than the diameter of the LED body. The step formed by the large circle and the small circle is the same as the bottom of the LED. The steps of the LED are matched to play a positioning role; the structural form of the large circle and the small circle forms an open structure from large to small, which cooperates with the arc top of the LED to play an installation guide role.

As shown in Figures 2 to 5, the anti-light-crossing structure 2 is designed with 4 small protrusions inside the circular hole structure. It forms an interference fit with the outer circle of the LED, which results in the deformation of the anti-light stringing structural member to form a clamping force, and the anti-light stringing structural member 2 is fixed on the LED.

In this embodiment, there are 10 LEDs, and the 10 anti-light-crossing structural members 2 can be put on 10 LEDs at one time. Since the bottom of the anti-light-crossing structural member 2 is designed as a step shape with a large circle and a small circle, it can play a very good role. The guiding function can accurately guide each LED into the corresponding circular hole of each corresponding anti-cross-light structure member 2, and the installation process is very simple. 4 small protrusions are designed inside the circular hole structure of the anti-light-crossing structural member 2, so that the contact area between the anti-crossing light structural member 2 and the LED is very small, and the space between the 4 small protrusions also provides the anti-light-crossing structure. The deformation of the component 2 leaves a space, and the strength of the anti-light string structure component 2 to fit into the LED does not need to be large, and at the same time, it can ensure that the light string prevention structure component 2 will not fall.

4 small protrusions are designed inside the small circle for the anti-light-crossing structural member 2. During the process that the anti-light-crossing structural member 2 is inserted into the LED, the four small protrusions are formed with the outer circle of the LED. The interference fit makes the anti-light-stringing structural member 2 deform to form a clamping force, and the anti-light-stringing structural member 2 is fixed on the LED.

As shown in Fig. 2 to Fig. 4 , the matching place between the panel 5 and the light guide column 1 is also a stepped hole, and the head of the anti-light-crossing structure 2 is designed with a chamfer, which plays a guiding role in the installation process of the panel 5; The stepped hole on the panel 5 cooperates with the head of the light-crossing prevention structural member 2 to form a closed isolation space to prevent light-crossing between the light guide columns 1 . The head of the anti-cross-light structure 2 is designed with steps for the installation of the light guide rod 1, and at the same time, the insertion depth of the light guide rod 1 can be positioned to prevent the light guide rod 1 from forming pressure on the head of the LED 4.

As shown in Fig. 3 and Fig. 5, the single anti-light streak structure 2 adopts a micro-connection method. Multiple anti-light streak structures can be installed on a group of LEDs at the same time, or they can be easily disassembled and used separately. . If the LEDs are designed according to a predetermined interval, a plurality of anti-cross light structural members 2 can be installed on a group of LEDs at a time, and the anti-cross light treatment is performed on the plurality of LEDs at the same time. The number of LEDs is the same and the installation efficiency is very high. If the LEDs are not designed according to the predetermined interval, the multiple light-crosslinking structural members 2 using micro-connection can be easily broken from the micro-connection to form a single anti-light-crosslinking structural member 2, which is suitable for various installation situations.

As shown in Figures 3 and 5, the outer circle of the light guide column 1 is designed with 4 small protrusions. The inner circle of the light stringing structural member forms an interference fit, which causes the anti-light stringing structural member 2 to deform to form a clamping force, and the light guide column 1 is fixed on the light stringing preventing structural member 2 . The bevels of the 4 small raised ends act as guides at the same time.

As shown in FIG. 6 , the neck of the light guide 1 is designed with a circle of grooves, which can reduce the mating area between the light guide 1 and the panel 5 , reduce the friction between the light guide 1 and the panel 5 , and facilitate the fitting and installation of the panel 5 . In this embodiment, there are 10 LEDs, and there are 10 holes on the panel 5 for installation with 10 light guide columns. Since the matching area between the panel and the light guide column is small, the panel is easy to disassemble and assemble. Take the light guide 1 down.

As shown in FIG. 2 , the bottom of the light guide column 1 is designed with an arc-shaped groove similar to the top of the LED, which can increase the matching length of the light guide column 1 and the anti-light streak structure 2, and increase the length of the light guide column 1 and the anti-light streak structure. 2, and at the same time, the height of the entire component of the anti-cross-light structure can be adjusted by adjusting the insertion depth of the light guide column 1, so as to adapt to occasions with different height requirements.
