Detailed description of the invention
Below with reference to accompanying drawings embodiments of the invention are described.First, with reference to Fig. 1-4, the first embodiment according to lens of the present invention is described.
Fig. 1 is the side view of the first embodiment according to the lens for the formation of ring-shaped light spot of the present invention.As shown in Figure 1, the lens for the formation of ring-shaped light spot according to the present invention comprise light inlet 10, lateral reflection wall 20 and ring-shaped light spot mouth 30.Light inlet 10 is formed as stereochemical structure, and light is injected in lens by this light inlet 10.The stereochemical structure of light inlet 10 is the deviations in order to carry out converging angles to light, reaches the object reducing optical emission exit footpath.
For example, the stereochemical structure of light inlet 10 can adopt triangular pyramidal, or conical, or hemispherical.Such as, as shown in Figure 1, light inlet 10 is conical, and with certain light inlet radian.Certainly, light inlet 10 also can adopt the taper shape without radian.In addition, Fig. 3 A3C also respectively illustrates and adopts triangular pyramidal and hemispheric light inlet.
Ring-shaped light spot mouth 30 is arranged to form ring-shaped light spot.As shown in Figure 2, ring-shaped light spot mouth 30 comprises reflecting segment 31 and outgoing section 32.Lateral reflection wall 20 is folded between light inlet 10 and outgoing section 32.
From principle, the process forming ring-shaped light spot is cooperatively interacted by reflecting segment 31, outgoing section 32 and lateral reflection wall 20 and realizes.The light path of light illustrates in fig. 2.First, light enters to inject lens from light inlet 10, then, light arrive reflecting segment 31, reflecting segment 31 for by light reflection to lateral reflection wall 20, lateral reflection wall 20 so will be reflected by reflecting segment 31 come light reflection to outgoing section 32, finally, light penetrates through outgoing section 32.
According to above-mentioned light path, at reflecting segment 31, light outwards can not shoot out from lens, light only can penetrate from outgoing section 32, and therefore, the projected area corresponding to reflecting segment 31 can not produce light, projected area corresponding to outgoing section 32 then forms the light of ring-type, forms ring-shaped light spot thus.
For reflecting segment 31, in order to make light reflect, in the present invention, following manner is adopted to form this reflecting segment 31.Specifically, reflecting segment 31 is designed to meet the condition making light that total reflection occur, this reflecting segment 31 has reflecting segment radian, and described reflecting segment radian is arranged to when light is incident to reflecting segment 31 from light inlet 10, makes light meet total reflection condition and realizes total reflection.
In order to more desirably make light be totally reflected after being incident to reflecting segment 31, also the surface design of light inlet 10 can be become have light inlet radian, making incident ray more can realize total reflection on reflecting segment 31 thus after shrinking deviation.That is, can the reflecting segment radian of design reflectivity section 31 individually, to make light be totally reflected after reflecting segment 31, also light inlet radian can be designed individually, make light by after light inlet incidence, to be easilier totally reflected on reflecting segment 31.In addition, also can the reflecting segment radian of design reflectivity section 31 and the light inlet radian of light inlet 10 matchingly, thus light is more successfully totally reflected after light inlet 10 is incident to reflecting segment 31 on reflecting segment 31.Design above-mentioned radian and can adopt specialty optics design software, such as Light Tools etc.
In the first embodiment of the present invention, as shown in the inside index path of Fig. 2, reflecting segment 31 is connected directly to outgoing section 32.As shown in figs.3 a and 3b, reflecting segment 31 and outgoing section 32 couple together the stereochemical structure forming above-mentioned ring-shaped light spot mouth 30, realize the total reflection of light simultaneously.The ring-shaped light spot mouth 30 formed thus has the stereochemical structure of taper, such as conical or triangular pyramidal, or with the taper shape of radian or triangular pyramidal.
As shown in Figure 3 C, reflecting segment 31 and outgoing section 32 also can be in same flat plane, form the taper not with radian thus.In this case, in order to make light be totally reflected after this taper not with radian, with regard to needing, the stereochemical structure of light inlet 10 being designed to have light inlet radian, making the light being incident to reflecting segment 31 can meet the condition of total reflection.
Lateral reflection wall 20 can be electroplated or post reflectance coating, thus carries out secondary reflection to the light reflected back from reflecting segment 31, makes light to outgoing section 32.Now, the light being incident to outgoing section 32 can not meet total reflection condition, makes the angled inclination outgoing of light refraction thus.
Therefore, by designing the respective face shape of light inlet, ring-shaped light spot mouth and lateral reflection wall and angle respect to one another, the illuminating effect of the ring-shaped light spot required for realization.Fig. 4 illustrates the different ring-shaped light spot illumination figure that the lens of different structure realize.As shown in Figure 4, by the angle of inclination of adjustment lateral reflection wall 20, or light inlet radian, or the corresponding radian of ring-shaped light spot mouth, the ring of light of different in width or size can be obtained.
In addition, the ring-shaped light spot of three kinds of different sizes in Fig. 4 is all schematic.According to optical projection principle, the distance between the region that ray cast arrives and light source position can have influence on the size of ring-shaped light spot.
