Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments to the present invention
It is further elaborated, but the scope of protection of present invention is not limited to following specific embodiments.
It is a kind of have can form the Lenticular lens of strip hot spot, including lens body, the lens body includes the
One incidence surface 1, the second incidence surface 2, the first fully reflecting surface 3, waterproof wall 4, the second fully reflecting surface 5 and exiting surface 6, light source is sent
A light part from the first incidence surface 1 injection after directly from the light extraction 6 collimate project, this some light all project, do not have
There are veiling glare, optics utilization rate light；Another part light is totally reflected by first successively after from second incidence surface 2, you enter
Face 3, the fully reflecting surface 5 of waterproof wall 4 and second, finally collimate and project from the exiting surface 6, and first fully reflecting surface 3
Rim ray overlapped through the waterproof wall 4 with the rim ray of second fully reflecting surface 5 or only minimum angle
Degree is poor, and so there will be no unnecessary light to get on waterproof wall, so as to improve the optics utilization rate of lens.It is described here
The thickness of waterproof wall 4 is 3-6mm.The present embodiment waterproof wall 4 takes preferred value 3.5mm.
In the present embodiment, second incidence surface 2, the first fully reflecting surface 3, waterproof wall 4 second fully reflecting surface 5 and goes out
Smooth surface 6 is with the symmetrically disposed about surrounding in first incidence surface 1 of first incidence surface 1；First incidence surface 1
For circular convex smooth surface.The fully reflecting surface 5 of first fully reflecting surface 3 and second is plane or smooth surface.Will be anti-
Water wall 4 is arranged between the first fully reflecting surface 3 and the second fully reflecting surface 5, that is, is arranged in the middle part of lens so that whole lens are more
It is easy to injection molding, it is more superior to fix optical property in appearance and size one；The design simultaneously causes what is sent from light source center
Light can collimate outgoing, and the light for not having light source center outgoing enters the band waterproof construction position for replacing optical surface, from
And veiling glare is inhibited, and improve light utilization ratio.
As Figure 2-3, second fully reflecting surface 5 is partially provided with cuing open with what vertical direction shape formed an angle
Section 7, be irradiated to the cutting plane 7 light form total reflection after be folded to the opposite side of cutting plane 7, then by the exit facet 6
Get to the dark space position of metope 10.The number of degrees of the angle are：3-15 degree.5 degree of the preferred value of the present embodiment degree of selecting the role.
The cutting plane 7 is plane or smooth surface, and the shape of change cutting plane 7 can adjust the reflection of emergent light
Position, realize the compensation to dark space.
The lens body is provided with substrate (being not drawn into figure), and the substrate width direction is perpendicular to metope 10, long
Degree is oriented parallel to metope 10, and length of the cutting plane 7 in zig direction is more than the length with width.It is common
Wall lamp lens are the circular rotating symmetric lenses made using installation base plate width as lens diameter.However, lens are in installation
The spacing of length direction is greater than installation base plate width, and the length in this direction can suitably amplify.Utilize the present invention's
Lens array, by going out cutting plane in the second fully reflecting surface partial sectional, length of the lens in zig direction is more than and width
Direction is spent, in addition to realizing the function of compensation dark space, the light-emitting area of increase lens is additionally aided, so as to washing for reducing glass
Wall height.
As illustrated in figures 4-5, the exiting surface is provided with for forming strip hot spot from middle position to extending around
Micro-structural 8, the micro-structural include some micro-structural members 9, and the curvature of the first 9 liang of orthogonal directions of the micro-structural is inconsistent, specifically
Ground, curvature of the micro-structural member 9 in laterally and longitudinally direction is enclosed outward from center uniformly successively decreases, and horizontal direction and longitudinal direction
The tolerance that direction is uniformly successively decreased differs, and micro-structural member 9 is ellipsoid or other inconsistent spies of curvature with two orthogonal directions
The free form surface of property.
The downward projection of the micro-structural is rectangle, and the transverse direction of the projection rectangle and vertical ratio are 1:0.95-
1.05。
The big direction of first 9 curvature of the micro-structural is used to form hot spot long side, and the small direction of curvature is narrow for forming hot spot
Side；Outside from center, the curvature in the small direction of micro-structural 9 curvature of member is gradually reduced.
It can be realized by the curvature for two orthogonal directions for individually adjusting each micro-structural member and hot spot luminous intensity distribution is become more meticulous
Processing.By solve the problems, such as using high color temperature white light lamp bead duration strip light spots it is narrow while it is yellow while exemplified by, using multigroup different micro-
Structural elements combine, and the narrow edge direction curvature of one group of micro-structural member is larger to be used for desalinating bottom Huang side, the curvature of one group of micro-structural member compared with
Small to wash wall height for improving, suite rate micro-structural member placed in the middle is used for soft hot spot transition, so as to highly be sacrificed washing wall
Bottom Huang side is eliminated in the case of less.
Exemplified by improving and wash the wall uniformity, it is mostly to be determined by the luminous intensity distribution on narrow side to wash the metope uniformity, can be led to more
Using the micro-structural member of multigroup different narrow side curvature, the narrow descending distribution of side curvature of difference group, wall can be washed not sacrificing
The uniformity that lens integrally wash wall is greatly improved in the case of height.
The microstructure design of the present invention can efficiently solve the mixed light problem using the narrow side of polychrome lamp bead duration strip light spots；
Can efficiently solve using high color temperature white light lamp bead duration strip light spots it is narrow while it is yellow while problem；Wall lamp bottom can be efficiently solved
Portion dark space and non-uniform phenomenon problem etc..
The announcement and teaching of book according to the above description, those skilled in the art in the invention can also be to above-mentioned embodiment party
Formula is changed and changed.Therefore, the invention is not limited in embodiment disclosed and described above, to the one of invention
A little modifications and changes should also be as falling into the scope of the claims of the present invention.In addition, although used in this specification
Some specific terms, but these terms are merely for convenience of description, do not form any restrictions to invention.
