Description
Technical field
The invention belongs to lens technologies field, particularly a kind of side entering type optical lens structure.
Background technology
The optical lens structure that prior art is provided has following defects：Existing lens lamp bead is placed in lens bottom
The heart, lens are thicker.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of side entering type optical lens structure, it includes lens body,
The lens body upper surface is cambered surface outwardly, and the bottom of the lens body is provided with multiple hot pressing reflection sites, light
Source is injected by the side of the lens body, and light is by the bottom surface of the lens body with upper surface with more than critical angle
Angle inject, incident ray completes total reflection in bottom surface and the upper surface of the lens body, when light reflex to it is described
Behind hot pressing reflection site, the reflection angle of the light is changed by the reflection site, and reflexes to the top of the lens,
Reflected away in the lensed tip；The reflection site is the prominent structure that mold is formed, and reflection site upper surface is
Arcwall face.
It is preferred that the cross section of the lens body for circle, the lens body be divided into intensive dot area with it is sparse
Dot area, the intensive dot area is the radius less circle more circular than the lens body cross section, its center of circle and institute
The circular identical of lens body cross section is stated, the circular annular region outside the intensive dot area in the lens body is
Sparse dot area, the hot pressing reflection site in the reflection dot area is uniformly distributed, the hot pressing of the sparse dot area
Also to be uniformly distributed, the hot pressing reflection dot density of the intensive dot area is higher than the sparse dot area for reflection site.
The invention has the advantages that：
The side entering type optical lens structure that the present invention is provided utilizes on lens guide-lighting plate technique, if upper surface is
Plane, then the light big with vertical direction angle for being reflected from lower surface and being come can be all-trans by upper surface and be emitted back towards bottom surface, so that
So that upper surface can only go out low-angle light, and high angle scattered light goes out not going；And upper surface is set to cambered surface by the present invention, then come from down
The high angle scattered light on surface will not be completely reflected back, and part can reflect away；Another part is reflected back, and continues along saturating
Mirror horizontal direction reflects propagation up and down, and until meeting refracting condition, refraction is gone out；Using reflecting site by the reflection of uniform light
To lensed tip, reflected away by lensed tip, light is more evenly distributed, reach product it is more frivolous the characteristics of.
Certainly, implement any product of the invention to it is not absolutely required to while reaching all the above advantage.
Brief description of the drawings
Technical scheme in order to illustrate more clearly the embodiments of the present invention, uses required for being described to embodiment below
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for ability
For the those of ordinary skill of domain, on the premise of not paying creative work, can also obtain other attached according to these accompanying drawings
Figure.
Fig. 1 is side entering type optical lens structure schematic diagram provided in an embodiment of the present invention；
Fig. 2 is the cross-sectional of lens body provided in an embodiment of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in figure 1, the invention provides a kind of side entering type optical lens structure, it includes lens body 3, the lens
The upper surface of body 3 is cambered surface outwardly, and the bottom of the lens body 3 is provided with multiple hot pressing reflection sites 4, and light source passes through
The side of the lens body 3 is injected, and light is by the bottom surface of the lens body 3 with upper surface with the angle more than critical angle
Degree is injected, and incident ray completes total reflection in the bottom surface of the lens body 3 with upper surface, when light reflexes to the hot pressing
Behind reflection site 4, the reflection angle of the light is changed by the reflection site 4, and reflex to the top of the lens body 3
Portion, reflects away at the top of the lens body 3；The reflection site 4 is the prominent structure that mold is formed, the reflection site
4 upper surfaces are arcwall face.
As shown in Fig. 2 the cross section of the lens body 3 of the present embodiment offer is circle, 3 points of the lens body is
Intensive dot area 2 and sparse dot area 1, the intensive dot area 2 are half more circular than the lens body cross section
The less circle in footpath, its center of circle is identical with the circle in the lens body cross section, the intensive site in the lens body
Circular annular region outside region 2 is sparse dot area 1, and the hot pressing reflection site of the intensive dot area 2 is uniformly distributed,
The hot pressing reflection site of the sparse dot area 1 is also to be uniformly distributed, and the hot pressing reflection site of the intensive dot area 2 is close
Degree is higher than the sparse dot area 1.
The side entering type optical lens structure that the present invention is provided utilizes on lens guide-lighting plate technique, if upper surface is
Plane, then the light big with vertical direction angle for being reflected from lower surface and being come can be all-trans by upper surface and be emitted back towards bottom surface, so that
So that upper surface can only go out low-angle light, and high angle scattered light goes out not going；And upper surface is set to cambered surface by the present invention, then come from down
The high angle scattered light on surface will not be completely reflected back, and part can reflect away；Another part is reflected back, and continues along saturating
Mirror horizontal direction reflects propagation up and down, and until meeting refracting condition, refraction is gone out；Using reflecting site by the reflection of uniform light
To lensed tip, reflected away by lensed tip, light is more evenly distributed, reach product it is more frivolous the characteristics of.
