Abstract
A novel transparent light guide structure belongs to the technical field of electrical equipment manufacturing, relates to the fields of light signal devices or lighting devices of automobiles and other devices needing light signal devices or lighting devices, and particularly relates to a light guide structure based on transparent materials. The light guide structure includes an incident end face, a light mixing region, a turning region, and a visible region. The utility model discloses a light guide structure can overcome the light-emitting end bright spot defect that exists in the light guide uses, solves the inhomogeneous shortcoming of optical effect and simultaneously, guarantees that it has more for pleasing to the eye visual effect.
Description
Technical Field
The utility model belongs to the technical field of electrical equipment makes, concretely relates to novel transparent light guide structure.
Background
At present, in order to meet the requirements of attractive appearance and practicability, more and more light guides are adopted for light signals or lighting devices in the fields of automobiles or other fields, and generally two light guides are adopted, wherein one light guide is in a shape of a nearly cylindrical long strip, and a light source is arranged at one end or two ends of the light guide; the other is a thick-wall light guide which is in a rectangular belt shape, and a plurality of light sources are arranged at intervals on the rear side, so that a dynamic optical effect can be realized. In the first type, the light-emitting end of the existing light guide is easy to have the defect of bright spots, and the optical effect is difficult to be made uniform, which is difficult to overcome.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve not enough that prior art exists, provided a novel transparent light guide structure, it specifically includes: the device comprises an incident end face 1, a light mixing area 2, a turning area 3 and a visible area 4;
wherein the incident end face 1 is at one end of the light guide, and is arranged in sequence from the following: the light mixing area 2, the turning area 3 and the visible area 4;
the incident end face 1 is of a plane structure, the light mixing area 2 is of a plum-blossom-shaped columnar structure formed by arc cutting of a cylindrical surface, the outer side of the turning area 3 is a groove formed by densely arranging and cutting small sections of arcs, and the inner side of the turning area 3 is an optical surface formed by a large-area gradual-change arc.
The novel transparent light guide adopts one of polycarbonate, polymethyl methacrylate or glass as a transparent material.
The utility model discloses the technical problem that will solve is: aiming at the defects of bright spot at the light outlet end and uneven optical effect existing in the use of the light guide, the optical structure at the light inlet end of the light guide is completely new designed, so that the light guide obtains good appearance effect.
The utility model discloses a novel transparent light guide structure makes the pointolite form even optical effect in visual region through its transmission back, and it is regional that the light-emitting end can not form obvious bright spot, moreover the utility model discloses a light guide structure is under the condition of not lightening the light source, and difficult through visual surface is seen such as its mounting structure and optical structure to light-emitting end bright spot defect, the inhomogeneous shortcoming of optical effect that exist have guaranteed that it has more for pleasing to the eye visual effect in having overcome the light guide and using simultaneously.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
A novel transparent light guide structure specifically comprises: the device comprises an incident end face 1, a light mixing area 2, a turning area 3 and a visible area 4; arranged in sequence from the light incident end are: an incident end face 1, a light mixing area 2, a turning area 3 and a visible area 4, as shown in FIG. 1.
In the novel transparent light guide structure, the incident end face 1 is a plane structure,
the structure of the light mixing area 2 is a quincuncial columnar structure formed by cutting a cylindrical surface by an arc, as shown in fig. 2.
The outer side of the turning zone 3 is a groove-shaped optical structure formed by densely arranging and cutting small sections of arcs, and the inner side is an optical structure formed by a gradual-changing arc with a larger area, as shown in fig. 3.
Through the utility model discloses a novel transparent light guide structure can effectively improve prior art light guide light end structure and have the bright spot defect, and prior art light guide structure is as shown in fig. 4, the utility model discloses at the point light source through its after propagating at the even optical effect of visual regional formation, the light-emitting end can not form obvious bright spot region, and concrete effect is as shown in fig. 5.
The novel transparent light guide structure can be prepared by adopting one of Polycarbonate (PC), polymethyl methacrylate (PMMA) and glass. The light source used may be a Light Emitting Diode (LED), a Laser Diode (LD), or the like.
When the novel transparent light guide structure is not lightened, the installation structure, the optical structure and the like of the novel transparent light guide structure are not easy to see through the visible surface.
The novel transparent light guide structure can be applied to the field of automobiles and other fields needing light signals.
This concludes the description of the embodiments of the present invention.
