The utility model relates to the field of light-emitting electronic badge products, in particular to a
light guide optical fiber electronic badge which comprises a badge body and a
light source control module, the badge body comprises a front piece and a back piece, an installation space is formed between the front piece and the back piece, the front piece is provided with a
light guide optical fiber and a wire penetrating hole, and the
light source control module comprises a circuit board, a button
cell, a light-emitting part and a
control switch. The circuit board is divided into a back connecting piece area and an edge connecting piece area, one face is an integrated
layout face, the other face is a back face, a circuit structure comprising a battery connecting end position connected with a
button battery, a control connecting end position connected with a
control switch and a
light source connecting end position connected with a light-emitting part is arranged on the integrated
layout face, and the edge connecting piece area is provided with a protruding part. The corresponding bare area is a
light guide lamp beam area, the light source connecting end faces the light guide lamp beam area, and the light guide
optical fiber tightens the
butt joint light-emitting part in the light guide lamp beam area. The structure is compact, light guide of small graphs is facilitated, the installation and placement space can be reduced, and arrangement and application of small electronic badges can be achieved.
