For example, the stereochemical structure of light inlet 10 can adopt triangular pyramidal, or conical, or hemispherical.For example, 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 shows respectively and adopts triangular pyramidal and hemispheric light inlet.
Ring-shaped light spot mouth 30 arranges in order 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 that forms ring-shaped light spot cooperatively interacts to realize with lateral reflection wall 20 by reflecting segment 31, outgoing section 32.The light path of light is illustrated in Fig. 2.First, light enters to inject lens from light inlet 10, then, light incident arrives reflecting segment 31, reflecting segment 31 for by light reflection to lateral reflection wall 20, lateral reflection wall 20 and then the light reflection that will be reflected by reflecting segment 31 comes are to outgoing section 32, finally, light penetrates through outgoing section 32.
Known according to above-mentioned light path, at reflecting segment 31, light can outwards not shoot out from lens, light only can penetrate from outgoing section 32, and therefore, the corresponding projected area of reflecting segment 31 can not produce light, the corresponding projected area of outgoing section 32 forms the light of ring-type, forms thus ring-shaped light spot.
For reflecting segment 31, for light is reflected, in the utility model, adopt following manner to form this reflecting segment 31.Specifically, reflecting segment 31 is designed to meet the condition that makes light generation total reflection, this reflecting segment 31 has reflecting segment radian, and described reflecting segment radian is arranged to, in the time that light is incident to reflecting segment 31 from light inlet 10, makes light meet total reflection condition and realize total reflection.
In order more desirably to make light, after being incident to reflecting segment 31, total reflection occur, also the surface design of light inlet 10 can be become have light inlet radian, make thus incident ray more can on reflecting segment 31, realize total reflection after shrinking deviation.That is to say,, there is total reflection afterwards to make light be incident to reflecting segment 31 in the reflecting segment radian of design reflectivity section 31 individually, also can design individually light inlet radian, make light pass through, after light inlet incident, more easily on reflecting segment 31, total reflection to occur.In addition, the also reflecting segment radian of design reflectivity section 31 and the light inlet radian of light inlet 10 matchingly, thus make light more successfully on reflecting segment 31, total reflection occur after being incident to reflecting segment 31 through light inlet 10.Design above-mentioned radian and can adopt professional optical design software, such as Light Tools etc.
