[0006] By configuring the light guide column and the light isolation plate in the present invention, when a light source is incident on a corresponding light guide column, the light guide plates on both sides of the light guide column can isolate other light sources, thereby effectively reducing the problem of light crosstalk between different light sources.

[0007] Preferably, a sealing groove for installing a sealing strip is further provided on the front side of the light guide plate body, and the sealing groove is recessed from the front side to the back side of the light guide plate body.

[0008] Preferably, the sealing groove is in the shape of a closed ring, and all the light guide columns are located on the end surface formed by the closed ring.

[0009] Through the setting of the sealing groove in the utility model, when the light guide plate body is installed on the cover plate of the inverter box through fasteners, inserting a sealing strip in the sealing groove can make the fixation between the light guide plate body and the cover plate tighter, and the sealing strip can better isolate dust so that the indicator light maintains a better display effect.

[0010] Preferably, the light guide plate body is further provided with a plurality of threaded holes, and the back side of the light guide plate body is further provided with convex humps cooperating with the threaded holes, and the position and number of the convex humps correspond to the threaded holes.

[0011] Through the arrangement of the threaded hole and the convex hump in the utility model, the thickness of the convex hump can be used as a safe distance between the light guide column and the light source component to prevent the raised light guide column from crushing the light source component when installing the light guide plate. The threaded hole is used to cooperate with fasteners such as screws.

[0012] Preferably, the threaded holes are evenly arranged around the light guide plate body.

[0013] Preferably, a plurality of limiting columns are provided on the back of the light panel.

[0014] By setting the limiting column in the utility model, the light guide plate body can be further stabilized when the light guide plate body is installed.

[0015] A lamp bead installation mechanism includes a circuit board body and an anti-cross-lighting light guide plate as described in any one of the above items, wherein the anti-cross-lighting light guide plate is installed on the circuit board body.
