Abstract
The utility model relates to a light conducting structure used for altering the light ray transmission path of a light source, which comprises a base board, wherein the edge of one side of the base board is convexly provided with a plurality of emission parts, a light conducting part is respectively connected between the base board and the emission parts, and one side of each of the light conducting parts is respectively provided with an internal reflection surface. One end of the internal reflection surface is connected to the position near one end of each of the emission parts which is far away from the base board, the other end of the internal reflection surface slantwise extends corresponding to each of the emission parts, and the projection of the internal reflection surface in the direction perpendicular to each of the emission parts is close to the edge of each of the emission parts. After emitted from the light source, light rays are leaded in the light conducting parts and are transmitted in the light conducting parts, wherein parts of the light rays are ripped into the internal reflection surfaces and are emitted along the directions perpendicular to the emission parts. Thus, the purpose that the light rays emitted from the inner reflection surfaces along the directions perpendicular to the emission parts are distributed in a wide visual zone is realized, and the utility model is convenient for the observation of users.
Description
[Ji Intraoperative field]
The utility model is a kind of light guide structure, particularly a kind of light guide structure that increases viewing area on the vertical direction.
[Bei Jing Ji Intraoperative]
Light guide structure is coupled a light guide structure and a light source in order to change the transmission path of light, can be behind light guide structure by the light that light source sends along certain transmission path, and last emitting area outgoing from light guide structure.
As shown in Figure 1, be a kind of existing light guide structure, this light guide structure comprises a substrate 10 ', one lateral edges place of this substrate 10 ' convexes with some emission parts 30 ', and be connected a light guide section 20 ' respectively between this substrate 10 ' and these emission parts 30 ', and these light guide sections 20 ' are respectively perpendicular to substrate 10 ', and being provided with an interior reflective surface 201 ' respectively at the place, centre position that these light guide sections 20 ' are gone up corresponding to emission part 30 ', these interior reflective surface 201 ' are coupled to emission part 30 ' in the mode that tilts.One light source 50 ' is arranged at a side of light guide section 20 ', after light source 50 ' emits beam, light can be directed in the light guide section 20 ', and in light guide section 20 ', follow total reflection and refraction principle and continue transmission, wherein there is part light can be incident to interior reflective surface 201 ', and locates to take place the outgoing along on of reflection back perpendicular to the direction of emission part 30 ' in interior reflective surface 201 '.
But, existing light guide structure is when design, interior reflective surface 201 ' only is provided with corresponding to the place, centre position of emission part 30 ', correspondingly, be confined in the very narrow viewing area along the light perpendicular to outgoing on the direction of emission part 30 ' by interior reflective surface 201 ', user's panesthesia brightness effects when observing is not good.
[summary of the invention]
Fundamental purpose of the present utility model is to provide a kind of light guide structure that increases viewing area on the vertical direction.
For reaching above purpose, the utility model provides a kind of light guide structure, and in order to change the light transmission path of a light source, it comprises: a substrate, and a lateral edges of substrate convexes with some emission parts; Be connected with a light guide section respectively between substrate and these emission parts, and a side of these light guide sections is respectively equipped with an interior reflective surface, one end of interior reflective surface is connected on the emission part away near the end of substrate, the other end of interior reflective surface then tilt to extend with respect to emission part, and interior reflective surface is perpendicular to the edge of the projection on the direction of emission part near emission part; After light is sent by light source, import light guide section and also in light guide section, transmit, wherein part light can be incident to interior reflective surface and along the direction outgoing perpendicular to emission part.
Skill Intraoperative is arranged in now mutually, by interior reflective surface along perpendicular to the distribution of light of outgoing on the direction of emission part in the viewing area of broad, be convenient to user's observation.

Fig. 2 is the three-dimensional view of the utility model light guide structure.
Fig. 3 is the projection view of the utility model light guide structure.
[embodiment]
See also Fig. 2 and shown in Figure 3, the utility model light guide structure comprises a substrate 10, and in present embodiment, this substrate 10 is provided with plurality of gaps 101, forms a unit between adjacent two gaps 101.And a lateral edges place of this substrate 10 convexes with some emission parts 30, wherein, be provided with an emission part 30 in the unit, in present embodiment, these emission parts 30 are parallel to substrate 10, and an end of emission part 30 is connected to a lateral edges of substrate 10, and the other end of emission part 30 is then stretched out by a lateral edges of substrate 10.In addition, these emission parts 30 are arranged to semi-cylindrical.
And between this substrate 10 and these emission parts 30, be connected a light guide section 20 respectively, and these light guide sections 20 are respectively perpendicular to substrate 10, and being respectively equipped with an interior reflective surface 201 in a side of these light guide sections 20, these interior reflective surface 201 are coupled to emission part 30 in the mode that tilts.Wherein, one end of interior reflective surface 201 is connected on the emission part 30 away near the end of substrate 10, the other end of interior reflective surface 201 then tilts to extend with respect to emission part 30, and interior reflective surface 201 is perpendicular to the edge of the projection on the direction of emission part 30 near emission part 30.
One light source 50 is arranged at a side of light guide section 20, after light source 50 emits beam, light can be directed in the light guide section 20, and in light guide section 20, follow total reflection and refraction principle and continue transmission, wherein there is part light can be incident to interior reflective surface 201, and the outgoing on perpendicular to the direction of emission part 30 of reflection back takes place at interior reflective surface 201 places.Because interior reflective surface 201 is bigger perpendicular to the view field on the direction of emission part 30, thereby can guarantee from interior reflective surface 201 enough big perpendicular to the zone that light covered of the direction outgoing of emission part 30, that is, increase user's viewing area, be convenient to user's observation.
