Embodiment
The advantages of the utility model is expanded on further below in conjunction with accompanying drawing and specific embodiment.
Refering to Fig. 1, in the utility model, light guide 100 is equally made up of two end faces, respectively incidence surface 110 and light extraction
Face 120, after incidence surface 110 receives the light that a light source is sent, whole light guide 100 will be passed through, and shine from light extraction at exiting surface 120
It is bright.For the light guide 100, incidence surface 110 be divided into structure it is multiple enter light basal plane 111, and be arranged to and light guide 100
Optical axis it is vertical, it is each enter light basal plane 111 will receive the light extraction of light source, and the light extraction of light source is equally divided into multiple.It will enter
Light basal plane 111 is arranged to vertical with optical axis, then when it receives light as with optical axis in a parallel direction, is incident into light basal plane 111
When will be vertical with entering light basal plane 111.And at exiting surface 120, its part extends to the direction away from incidence surface 110, is formed extremely
A few protuberance 112, extension of the protuberance 112 as light guide 100, its position extended to is also light can in light guide 100
The position propagated and illuminated.On the protuberance 112, the end face away from incidence surface 110 is provided with multiple light extraction basal planes 113, light extraction
Basal plane 113 is corresponding with entering light basal plane 111, the directional light exiting parallel that will enter light basal plane 111 and receive.After said structure,
The light vertical incidence that light source is sent is propagated to after entering light basal plane 111 along light guide 100, and can be from the light extraction basal plane of protuberance 112
113 outgoing.The light distribution effect of final light extraction formation, also it is what a plurality of light belt was formed due to multiple segmentations of light extraction basal plane 113
Illumination, ensure that the requirement of user on illuminating effect first.
In one preferred embodiment, it is in inclined-plane that it is overall, which to be configured to it, for incidence surface 110, is applicable to using the light guide 100 not
Luminous intensity distribution or moulding with vehicle, and because the inclined-plane moulding of incidence surface 110 shape will have angle between its optical axis, it is therefore, right
It is each enter light basal plane 111 be configured into light basal plane 111 and optical axis still to be vertically arranged, and it is multiple enter light basal plane 111 combination shape
It is in step-like into the adjacent light basal plane 111 that enters, ultimately forms in globality as the incidence surface 110 on inclined-plane.
In above-described embodiment, enter light basal plane 111 and include joint face and receiving plane, receiving plane is to be set on light basal plane 111
The end face vertical with optical axis is set to, the light parallel to optical axis that light source is sent will be propagated to all on receiving plane, and joint face is
Enter the end face for being arranged to parallel with optical axis on light basal plane 111, the adjacent light basal plane 111 that enters is connected, it is step-like so as to be formed
Structure.Because joint face is parallel with optical axis, therefore, the light of light source will not be incident in joint face.
After light guide 100 has above-mentioned moulding, refering to Fig. 2-4, the structure for the optical system 200 with the light guide 100 is shown
Meaning.In this embodiment, optical system 200 is additionally provided with light source assembly 210 and reflecting element 220.Due to user in the prior art
Can from external observation to car light in LED bright spots the reason for be that light source is disposed directly on the rear of light guide 100, and light guide
The gap on 100 sides can leak out LED bright spots.And in the utility model, one reflective yuan has been newly increased in optical system 200
Part 220, the light source assembly 210 that has of original are arranged on the outside of the incidence surface 110 of light guide 100, have light source in it, light source goes out
Light direction is in the optical axis direction basically perpendicular to light guide 100, if namely light source light extraction without under external intervention, will be unable to be injected into
In light guide 100.Therefore, reflecting element 220 is set towards light source, and its top includes a reflecting surface 221, and reflecting surface 221 will connect
Receive the light that light source is sent and reflect the light extraction along a reflection direction, a reflected light and final incidence are upwardly formed in the reflection side
To entering light basal plane 111.And it is parallel with optical axis due to entering light basal plane 111, therefore, reflection direction need to be parallel with optical axis, then reflective member
Also towards light guide 100, the visual reflecting element 220 is the setting of " bending place " to part 220 for part while towards light source.Simultaneously
For the multiple protruding portion 112 on corresponding light guide 100, reflecting element 220 and light source are also equipped with multiple, and each protuberance 112 is right
One group of light source and reflecting element 220 should be configured with, then 220, a light source, reflecting element protuberances 112 can be regarded
Optical assembly is assembled for one.With above-mentioned with postponing, because light source is no longer set directly at the dead astern of light guide 100, or even can be hidden
The inside of optical system 200 is ensconced, user will be unable to see the LED bright spots in light source, greatly carries from which angle
The high Consumer's Experience of car light.
In one preferred embodiment, reflecting element 220 is arranged to reflector, and each luminous evening is towards setting at adjacent light source
Fixed part is equipped with, the pcb board provided with light source is just arranged in the fixed part in light source assembly 210 so that a reflector part is made
Reflection is used, and another part again can fixed light source.
In further preferred embodiment, protuberance 112 is that reflecting element 220 is respectively three groups, each group of reflecting element
220 is continuous but unsmooth including multiple reflecting units in matrix form distribution, namely the single moulding of reflecting element 220, by more
The individual reflecting unit composition having at complications.It is understood that so setting is advantageous in that, because light guide 100 is with making
Light is also only provided with the part of protuberance 112, therefore reflecting unit also need to only be arranged on the part, and other parts can be used as
Fixed pcb board is used.Meanwhile it is continuous for moulding, adjacent reflecting unit is adjacent to respective edge, so as to final one into
Type.
It is further preferred that at the incidence surface 110 and exiting surface 120 of light guide 100, the surface treatment of textured can be made, with
Preferably improve efficiency and uniformity.
, can be by its application to car light after above-mentioned optical system 200.There is bracket component, decoration element in car light,
Optical system 200 is fixed in decoration element, by decoration element to whole vehicle light shape, and is finally installed jointly with decoration element
To bracket component.
To coordinate the configuration of at least one protuberance 112 on the exiting surface 120 of light guide 100, decoration element is provided with insertion
At least one framework, formation is available for the space that protuberance 112 passes through, and each protuberance 112 partially passes through the framework, and with
Framework gap coordinates, so as to complete the fixed installation of optical system 200.
It should be noted that embodiment of the present utility model has preferable implementation, and not the utility model is appointed
The limitation of what form, any one skilled in the art change or are modified to possibly also with the technology contents of the disclosure above
Same effective embodiment, as long as without departing from the content of technical solutions of the utility model, according to the technical essence of the utility model pair
Any modification or equivalent variations and modification that above example is made, in the range of still falling within technical solutions of the utility model.
