[0002] In the signal receiving box, an indicator light is needed to display the status. When one of the light sources is turned on, the light will be transmitted to the light outlet of another light source, forming a light crosstalk phenomenon and causing misreading.

[0003] According to a disclosed anti-light-crosstalk structure installed on an LED (authorization announcement number: CN111928207A), "an anti-light-crosstalk structure installed on an LED, including multiple LEDs welded on a printed circuit board, including multiple anti-light-crosstalk structural parts and light guide columns; the anti-light-crosstalk structural parts are mounted on the LEDs, the light guide columns are mounted on the anti-light-crosstalk structural parts, and a panel is installed on the head of the light guide columns; the light guide columns are used to transmit the light emitted by the LED to the corresponding position of the panel. The anti-light-crosstalk structure can solve the problems that the anti-light-crosstalk structural parts occupy a large space, are time-consuming and labor-intensive to install, and occupy printed circuit board space. Compared with various existing anti-light-crosstalk structural parts, the anti-light-crosstalk structure is simple in form, small in size, and easy to install. It does not need to occupy printed circuit board space during installation and can effectively avoid light crosstalk between LEDs."

In actual use, light crosstalk may occur, that is, a light source enters a non-original optical path through the connecting part between optical paths, resulting in confusion of light output. Therefore, an anti-light crosstalk light guide column is proposed. Utility Model Content
