It is the part of the embodiment rather than whole embodiments of the utility model, the embodiment based on the utility model, the skill of this field
The other embodiment that art personnel are obtained without creative efforts belongs to the model of the utility model protection
It encloses.In addition, all connection/connection relations arrived involved in patent, not singly refer to component and directly connect, and refer to can be according to specific
Performance, by adding or reducing couple auxiliary, to form more preferably coupling structure.In the utility model it is involved it is upper,
Under, the orientation such as left and right description be only for the mutual alignment relation of each component part of the utility model in attached drawing.
Each technical characteristic in the utility model, can be with combination of interactions under the premise of not conflicting conflict.
With reference to Fig. 1~4, wherein, Fig. 1~4 show the structure diagram of the utility model lens one embodiment
And phantom, such as scheme, a kind of lens of the present embodiment, including incidence surface 100 and light-emitting surface 200, light-emitting surface 200 is included simultaneously
Row and symmetrical first area 201 and second area 202, the first area 201 and second area 202 are respectively border circular areas,
First area 201 is provided with to inclined first inclined-plane 210 in incidence surface direction, and second area 202 is provided with to incidence surface direction
Inclined first inclined-plane 220,210 and second inclined-plane 220 of the first inclined-plane can be planar structure or globoidal structure.
In the present embodiment, there are four the first inclined-plane 210 and second inclined-planes 220 for the setting of light-emitting surface 200.This first tiltedly
Face 210 is consistent with the extending direction on the second inclined-plane 220, specially phase left and right directions extend so that light from light-emitting surface project when
Downwards, when for dynamo lighting set, be conducive to the eye that direct irradiation by light earthward deflection, is avoided to head on crowd and
Generate other side dazzling.Each first inclined-plane, 211 inclined direction is consistent, and all first inclined-planes 210 are uniform in the same direction
Arrangement, specially uniformly arrangement from up to down so that uniform light reflects, so as to obtain the hot spot of brightness uniformity.Second inclined-plane
220 be to the inclined cambered surface in incidence surface direction, the extending direction phase of the extending direction on the second inclined-plane 220 and the first inclined-plane 210
Together, the effect on the second inclined-plane 220 is identical with the effect on the first inclined-plane 210, and the second inclined-plane is arranged on the second area 202
The position of upper middle may be such that the light irradiated upwards by being reflected downwards during second inclined-plane 220, avoids some light
Direct irradiation head on crowd eye and make other side generate it is dazzling, the part that rib grid structure is not provided in second area 202 is flat
Face structure 230 so that the light and the angle on ground projected from the part planar structure 230, which is more than from the second inclined-plane 220, to be projected
Light and the angle on ground, so that the irradiation distance before reaching ground from the light that the planar structure 230 projects is longer,
Farther ground can be irradiated.
The one end of first inclined-plane 210 from close to one end of second area 202 to far from second area 202 tilts so that light
It is biased to reflect close to the direction of second area 202 when line projects, i.e., light is offset inward, and is conducive to increase the bright of spot center
Degree, makes irradiation apparent.
Incidence surface 100 corresponds to first area 201 and is provided with the first incidence surface 110, and corresponding second area 202 is provided with second
Incidence surface 120.First incidence surface 110 includes 111 and second plane of refraction 112 of first refractive face, 111 and second folding of first refractive face
Penetrate face 112 and surround one for accommodating the accommodating space 113 of light source device, first refractive face 111 be the cambered surface that outwardly protrudes or
The compound eye rib piece group outwardly protruded, which, which has the light of injection, gathers effect, is conducive to increase in hot spot
The brightness of the heart makes irradiation apparent, and the structure of the second incidence surface 120 is roughly the same with the structure of the first incidence surface.Light source device
It being arranged in accommodating space 113, the light that light source device projects injects lens by the first incidence surface 110 and unirefringence occurs,
A part of light is projected by light-emitting surface so as to which second of refraction occur, and it is anti-that another part light first passes through cup-shaped lateral surface 300
It penetrates, then is projected by light-emitting surface, occur second and reflect, the refraction for the light that the light source device at the second incidence surface 120 projects
Process is similar at above-mentioned first incidence surface.
The present embodiment lens are also symmetrical arranged there are two cup-shaped lateral surface 300, and two cup-shaped lateral surfaces 300 correspond to respectively
The first area 201 and the second area 202.300 outer surface of cup-shaped lateral surface cover reflectance coating, for light into
Row reflection, has focusing light effect.
In the other embodiment of the utility model, the first inclined-plane can also be cambered surface, and similarly, the second inclined-plane can also be set
Plane is set to, according to the situation of required hot spot can carry out that setting is adaptively adjusted.
When the utility model lens are used for dynamo lighting set, the effect of lens causes light earthward to deviate, so that main
Hot spot upper edge be less than pedestrian's eye, avoid direct projection head on crowd eyes and generate dazzling.First inclined-plane 210 can also make light
The brightness of spot center can be improved to second area offset so that irradiation is apparent, is conducive to night running.
The preferred embodiment of the utility model is above are only, but the utility model is not restricted to the embodiment, be familiar with
Those skilled in the art can also make a variety of equivalent variations or replacement without departing from the spirit of the present invention, this
Equivalent deformation or replacement are all contained in the application claim limited range a bit.
