According to the application, the lamp bead holes 22 are formed in the light-transmitting plate 20, so that the lamp beads 31 on the PCB 30 can be at least partially embedded in the lamp bead holes 22, the distance between the lamp beads 31 and the light-emitting positions of the light-guiding columns 21 is reduced, the light guiding effect is good, the possibility of light scattering and other problems is effectively reduced, and on the basis, the number of parts of the indicator lamp structure is reduced because no additional light scattering preventing parts are required, so that the occupied space and equipment cost of the indicator lamp structure can be effectively reduced.
Referring to fig. 3 and 4, in some embodiments, the beads 31 are completely located in the bead holes 22.
It can be understood that the more the lamp beads 31 are located in the lamp bead holes 22, the smaller the distance between the lamp beads 31 and the light emergent positions of the light guide columns 21 is, the better the anti-light scattering effect is, and meanwhile, the more the lamp beads 31 are embedded into the lamp bead holes 22, the smaller the total thickness of the lamp beads 31 and the light-transmitting plate 20 is, the more compact the indicator lamp structure is to the whole structure, and the size of the whole machine can be effectively reduced.
Therefore, by designing the beads 31 to be entirely located within the bead holes 22, the anti-crosstalk effect can be maximized while minimizing the overall size of the indicator light structure.
In some embodiments, the light bead holes 22 extend into the light guide posts 21 such that the light bead holes 22 are able to fully receive the light beads 31 even though the light-transmitting plate 20 is thinner than the height of the light beads 31.
