The application provides a light guide structure, including light guide plate and locate a plurality of first leaded light posts and a plurality of second leaded light posts on the light guide plate. The first light guide column comprises a first light incident surface, a first light emergent surface and a first side wall, wherein a plurality of first light emergent surfaces are arranged on the light guide plate at intervals, and the projection area of the first light emergent surface facing the first light incident surface is the same as the area of the first light incident surface; the second light guide column comprises a second light incident surface, a second light emergent surface and a second side wall, wherein a plurality of second light emergent surfaces are adjacently arranged on the light guide plate, and the projection area of the second light emergent surface towards the second light incident surface is smaller than the area of the second light incident surface.

Example 1
Referring to fig. 1-3, the light guiding structure 100 generally includes a light guiding plate 12, and a plurality of first light guiding columns 14 and a plurality of second light guiding columns 16 disposed on the light guiding plate 12. The light source may project light to the surface for display through either the first light guide pillar 14 or the second light guide pillar 16.
Specifically, the first light guiding pillar 14 includes a first light incident surface 40, a first sidewall 41 and a first light emergent surface 42, and the second light guiding pillar 16 includes a second light incident surface 60, a second sidewall 61 and a second light emergent surface 62. The light source may illuminate the first light guiding column 14 from the first light incident surface 40, the incident light may project from the first light emergent surface 42, the light source may illuminate the second light guiding column 16 from the second light incident surface 60, and the incident light may project from the second light emergent surface 62.
Further, the projected area of the first light emitting surface 42 facing the first light incident surface 40 is the same as the area of the first light incident surface 40, and the projected area of the second light emitting surface 62 facing the second light incident surface 60 is smaller than the area of the second light incident surface 60.
The first light-emitting surfaces 42 and the second light-emitting surfaces 62 are disposed on the light guide plate 12, the first light-emitting surfaces 42 are disposed at intervals, and the second light-emitting surfaces 62 are disposed adjacently. The intervals between the first light-emitting surfaces 42 are larger than the distances between the second light-emitting surfaces 62. In an embodiment, the plurality of second light emitting surfaces 62 may be arranged in an arc shape, and the second light incident surfaces 60 may be staggered due to the smaller distance between the first light emitting surfaces 42.
When the arrangement distance of the light sources is moderate, the light sources can be arranged at the position of the first light guide column 14, and the light enters the first light guide column 14 through the first light incident surface 41 and is projected out of the first light emergent surface 42 for display; when the arrangement distance of the light sources is relatively close, the light sources can be arranged at the position of the second light guiding column 16, and the light rays can be projected from the second light emitting surface 62 to be displayed after passing through the second light incident surface 61 and reaching the second light guiding column 16.
In other words, if the light sources are disposed at the positions of the first light guide columns 14 when the arrangement distance of the indication lamps is relatively close, a phenomenon of light channeling is liable to occur due to the relatively close distance between the plurality of light sources, which affects the display effect of the indication lamps. When the plurality of light sources are arranged at the position of the second light guide column 16, the distance between the light sources can be properly enlarged because the area of the second light incident surface 60 is larger than that of the second light emergent surface 62, so that the distance between the plurality of light sources is ensured, the phenomenon of light channeling caused by too small distance between the plurality of light sources is avoided, and the display effect of the indicator lamp is further ensured.
The first light guide column 14 and the second light guide column 16 can meet the light guide requirements of the indicator lamps arranged in different arrangements, so that the phenomenon of light channeling caused by the indicator lamps passing through the light guide mechanism is avoided, and the display effect of the indicator lamps on the electronic equipment is ensured.
Example two
On the basis of the first embodiment, the light guide structure provided by the application further has the following design:
referring to fig. 4, the first light guide column 14 includes a first light incident surface 40, a first sidewall 41, and a first light emergent surface 42. The inner wall of the first sidewall 41 may reflect the light, so that the light entering from the first light incident surface 40 may be projected onto the first light emergent surface 42.
The first light incident surface 40, the first side wall 41 and the first light emergent surface 42 are surrounded to form the first light guide column 14, and the inner wall of the first side wall 41 is made of a material that reflects light, for example, the inner wall of the first side wall 41 may be a mirror surface or a frosted surface. When the light source projects light into the first light guide column 14 through the first light incident surface 40, the inner wall of the first sidewall 41 is made of a material reflecting the light, so that the light cannot be transmitted out of the inner wall of the first sidewall 41, and further the light is projected out of the first light emergent surface 42, so that the light transmitted out of the inner wall of the first sidewall 41 to weaken the light projected by the first light emergent surface 42, or the light is transmitted to the adjacent first light guide column 14 from the inner wall of the first sidewall 41 to generate light channeling.
Example III
On the basis of the first embodiment, the light guide structure provided by the application further has the following design:
referring to fig. 5, the second light guide column 16 includes a second light incident surface 60, a second sidewall 61, and a second light emergent surface 62. The inner wall of the second sidewall 61 may reflect the light, so that the light entering from the second light incident surface 60 may be transmitted to the second light emergent surface 62.
The second light-guiding post 16 is formed by surrounding the second light-incident surface 60, the second side wall 61 and the second light-emergent surface 62, and the inner wall of the second side wall 61 is made of a material that reflects light, for example, the inner wall of the second side wall 61 may be a mirror surface or a frosted surface. When the light source projects light into the second light guide column 16 through the second light incident surface 60, the inner wall of the second side wall 61 is made of a material reflecting the light, so that the light cannot be transmitted out of the inner wall of the second side wall 61, and the optical fiber is further projected out of the second light emergent surface 62, thereby avoiding the weakening of the optical fiber projected by the second light emergent surface 62 due to the transmission of the light out of the inner wall of the second side wall 61, or the channeling of the light due to the transmission of the light from the inner wall of the second side wall 61 to the adjacent second light guide column 16.
In an embodiment, the second light incident surface 60 and the second light emergent surface 62 are circular, the second sidewall 61 includes a main body 611 and an extension portion 612, one end of the main body 611 is connected with the second light emergent surface 62, the other end is connected with the extension portion 612, one end of the extension portion 612 away from the main body 611 is connected with the second light incident surface 60, and the main body 611 is connected with the extension portion 612 in a bending manner.
Because the second light emitting surfaces 62 are disposed adjacently and have smaller spacing, the arrangement of the main body 611 and the extension portion 612 can increase the spacing between the second light incident surfaces 60 of the adjacent second light guiding columns 16, increase the distance between the light sources of the second light guiding columns 16, and avoid the light channeling phenomenon caused by too tight arrangement of the light sources, thereby ensuring the display effect of the indicator light.

The recess 120 divides the light guide plate 12 into a first portion 121 and a second portion 122. The first light-emitting surfaces 42 and the second light-emitting surfaces 62 are disposed on the first portion 121.
The recess 120 may be an annular structure, the recess 120 encloses the light guide plate 12 to form a first portion 121, and the periphery of the recess 120 forms a second portion 122. The recess 120 may form a drainage channel on the light guide plate 12, when the light guide structure 100 encounters a water flow, the water flow may flow along the drainage channel formed by the recess 120, thereby reducing the moisture on the first light emitting surface 42 and the second light emitting surface 62, and improving the waterproof performance of the light guide structure 100.
In an embodiment, at least one through hole 18 penetrating the light guide plate 12 is further provided on the light guide plate 12, and the through hole 18 is located on the second portion 122 of the light guide plate 12.
