Specific implementation mode
The utility model is described further below in conjunction with Figure of description.
Refringent/reflection lens as shown in Figure 1 are that material is made as integral structure with optical plastic, which, which has, is used for cloth
If the recess portion 01 of light source, light extraction refractive curvature 02, internal reflection curved surface, light extraction refractive curvature 02 is located at the left side of recess portion 01, interior anti-
The right side that curved surface is predominantly located at recess portion 01 is penetrated, recess portion 01 has first to enter anaclasis curved surface 05 so that is laid in the light source of recess portion
100 some light（It is indicated by the solid line in Fig. 2）Successively through first enter anaclasis curved surface 05, light extraction refractive curvature 02 refraction and to
Emit outside lens so that be laid in some light of the light source 100 of recess portion（It is indicated with chain-dotted line, dotted line in Fig. 2）Through internal reflection
Emit to outside lens after camber reflection, the direction that above-mentioned two parts light emits to outside lens is consistent, towards left side.
Specifically, first to enter anaclasis curved surface 05 be the left side for surrounding recess portion 01, light extraction refractive curvature 02 enters with first
Anaclasis curved surface is located at the left side of recess portion 01.First enters anaclasis curved surface 05 for concave surface, and light extraction refractive curvature 02 is convex surface.
The bottom surface of recess portion 01 forms second and enters anaclasis curved surface 06, and second to enter anaclasis curved surface 06 corresponding with internal reflection curved surface
So that being laid in some light of the light source of recess portion（It is indicated with chain-dotted line in Fig. 2）Enter 06 folding of anaclasis curved surface through second successively
It penetrates, internal reflection curved surface（Second internal reflection curved surface is only shown in figure）Emit to outside lens after reflection.
Internal reflection curved surface includes the first internal reflection curved surface 03, the second internal reflection curved surface 04 so that is laid in the light source of recess portion
Some light（It is represented by dotted lines in Fig. 2）Successively to saturating after the first internal reflection curved surface 03, the reflection of the second internal reflection curved surface 04
Emit outside mirror.
The right side of recess portion 01 constitutes the plane of incidence 07 of corresponding first internal reflection curved surface 03, and corresponding the is additionally provided on the lens
The exit facet 08 of two internal reflection curved surfaces 04, exit facet 08 is consistent with the direction of light extraction refractive curvature 02, towards left side.Therefore,
By the light of lens to transmitting on the left of lens.The plane of incidence 07, exit facet 08 are plane.
The lens greatly change the trend of light using reflection of enjoying a double blessing, very big using refraction, the form of combinations of reflections
That improves lens unidirectionally goes out light ability.
When the lens functions, LED light source 100 is laid in recess portion, the luminous of LED light source faces recess portion up, then LED
The light of light source is divided into left, center, right three parts and respectively enters lens：
The light of left half（It is indicated by the solid line in Fig. 2）Enter anaclasis curved surface 05, light extraction refractive curvature 02 through first successively
It reflects and emits to outside lens；Therebetween, first enters anaclasis curved surface and increases divergence of beam angle, and light extraction refractive curvature sends out light
Scattered angle further increases, to increase range of exposures；
The light of middle section（It is indicated with chain-dotted line in Fig. 2）Enter anaclasis curved surface 06 through second successively to reflect, in second
The reflection of reflecting curved surface 04, exit facet 08 emit after reflecting to outside lens；The some light enters anaclasis curved refractive by second
After level off to collimation, be emitted from left side using after the second internal reflection camber reflection；
The light of right half（It is represented by dashed line in Fig. 2）Reflected successively through the refraction of the plane of incidence 07, the first internal reflection curved surface 03,
The reflection of second internal reflection curved surface 04, exit facet 08 emit after reflecting outside backward lens；The some light is bent by the first internal reflection
Collimation is also leveled off to after the reflection of face, using transmitting outside backward lens after the second internal reflection camber reflection, exit facet refraction.
So that most of light is all from a direction（Left side in figure）Emit to outside lens.
