The light continuation reflected at incidence surface 100 is emitted according to original route, so as to ensure that uniform light is distributed in C0 ° of-C180 ° of directions.
The ratio of the specific finger widths of the ratio of width to height and height, highly refers to height of the symmetrical parabolic from lens base, and width is
Refer to the curve width of symmetrical parabolic.
Preferred embodiment is further used as, with reference to Fig. 5, on C90 ° of-C270 ° of cross sections of lens, lens enter light
Face 100 includes the sequentially connected first lateral straight line 101, the first top curve 102 and the second lateral straight line 103, lens light extraction
Face 200 includes the lateral straight line 104 of sequentially connected third, the second top curve 105 and the 4th lateral straight line 106；
First top curve 102 is straight line or microradian curve, and second top curve 105 is symmetrical parabolic
Line.
On C90 ° of-C270 ° of cross sections of lens, the first lateral straight line 101, the second lateral straight line 103, third are laterally straight
104 and the 4th lateral straight line 106 of line plays light and cuts light action.
First top curve 102 uses straight line or microradian curve, and light is focused.Second top curve 105 is
Symmetrical parabolic, for, into line convergence, realizing narrow angle illumination to light.
This lens effectively forms similar convex lens structures, can utilize the converging action of convex lens by light into guild
It is poly-, and pass through the setting of lateral plane of incidence and lateral exit plane, it is ensured that this lens meets the photograph of Windowsill lamp lens
Bright requirement.
Preferred embodiment is further used as, the ratio of width to height of first top curve 102 is：3~4.Set the width
After height ratio, lens incidence surface 100 can receive incident ray to the maximum extent, realize the effect of specular removal.
Preferred embodiment is further used as, the ratio of width to height of second top curve 105 is：2~3.In the ratio
In the range of, this lens can realize optimal convergence of rays effect.
Be further used as preferred embodiment, the height of the first lateral 101 and second lateral straight line 103 of straight line and
Ratio between its vertical range between lens centre is tan30 ° ± 5%.Lens centre, which refers to, places light source in lens
Position, i.e. 300 position of lamp bead in Fig. 4 and Fig. 5.
Be further used as preferred embodiment, the height of lateral 104 and the 4th lateral straight line 106 of straight line of third and
Ratio between its vertical range between lens centre is tan55 ° ± 5%.
So as to which lateral 104 and the 4th lateral straight line 106 of straight line of third is just received from the first lateral straight line 101 and second
The light that lateral straight line 103 is emitted under the limitation of this size, can be absorbed by Windowsill lamp lamp body after the outgoing of this some light, be kept away
Exempt from the generation of stray light, prevent the generation of glare phenomenon.
Narrow angle direction within the convergence of rays in C90 ° of-C270 ° of directions to 10 ° can be utilized convex lens by this lens
Light can orderly be controlled in the windowsill thickness range of 0.4m or so to the order of convergence of rays, avoid stray light by structure
Generation, realize that windowsill edge clear cuts light.
The present embodiment is precisely controlled lens incidence surface 100 and the size of lens light-emitting surface 200, C0 °-
The curvilinear path line of C180 ° of direction, lens incidence surface and light-emitting surface is substantially consistent with lambert's body light source isocandela curve path, really
It is vertical with opticpath to protect light-receiving surface, light is made not change original path outgoing.In C90 ° of-C270 ° of directions, lens incidence surface
100 have carried out wide-angle deviation with lens light-emitting surface 200 to light, by half peak light intensity of lambert's body light source, 120 ° of angle model
Light in enclosing is considered as effective light, and lens incidence surface 100 carries out first time convergence for plane or microradian curved surface to it.Lens go out
The convex lens shape thin for thick middle both sides of smooth surface 200, marginal dimension are located just on lens incidence surface 100 and receive effective sunlight
Edge deviation angle direction, Windowsill lamp lens light efficiency can promote more than 10% by the linking of this size than conventional lenses.Convex lens
Mirror curve the ratio of width to height can suitably be adjusted with windowsill thickness requirement in the range of the present embodiment.In lambert's body light source half-peak
Light other than the angular range that 120 ° of value light intensity is considered as invalid light, these light can be absorbed and be hidden by lamp body structure
Gear, reduces the generation of stray light.
As shown in Figure 6 and Figure 7, in Fig. 6 and Fig. 7, intermediate curve is C90 ° of-C270 ° of directions to the distribution curve flux of this lens
Distribution curve flux, distribution curve flux of the peripheral curve for C0 ° of-C180 ° of direction.It can be seen that by Fig. 6 and Fig. 7, C0 ° of-C180 ° of sides
To light light-emitting angle controls at the top of 70 ° -120 °, uniform illumination windowsill and two side.In C90 ° of-C270 ° of directions, light
Light-emitting angle is controlled within 10 °, realizes narrow thickness windowsill illumination.The half peak light intensity light distribution angle of this lens is about：C0°-
C180 ° of direction is 70 °, and C90 ° of-C270 ° of directions are 10 °.
Fig. 8, Fig. 9 and Figure 10 are that this lens is applied at the top of the generous windowsill for 3m*3m*0.4m of length and two side
Tracepro emulates hot spot figure, and by can be seen that three receiving plane hot spots of windowsill are uniform in figure, light control is stringenter, and edge cuts light
Clearly.
Therefore, this lens can realize preferable spotlight effect, and hot spot is more uniform, and light controls stringenter, side
It is clear that edge cuts light.
