In the present embodiment, light guide body 11 has external diameter reflective surface 111, internal diameter reflective surface 112 and exiting surface 113.Compared to internal diameter reflective surface 112, external diameter reflective surface 111 is positioned at the outside of exiting surface 113; And internal diameter reflective surface 112 is positioned at exiting surface 113 inner sides.In the present embodiment, the section of light guide body 11 is roughly rectangle, and therefore external diameter reflective surface 111 can be connected with internal diameter reflective surface 112 through bottom surface 114.But in other embodiments, the section of light guide body 11 can be also other arbitrary shape, for example, be circular, oval etc.Specifically, in the present embodiment, external diameter reflective surface 111 is designed to wavy structure W, and its function is having narration below.
In the present embodiment, starting point end S and destination terminal E the two at least one of them is incidence surface.Fig. 1 is only for giving an example, and because starting point end S is taken as incidence surface, therefore light source I is arranged on starting point end S.Certainly, in other embodiment, starting point end S and destination terminal E can be incidence surfaces, therefore in these embodiments, plural light source can be configured in respectively to starting point end S and destination terminal E.
Continue referring to Fig. 1, after light source I emits beam, light can enter light guide body 11 from starting point end S.By the reflection of external diameter reflective surface 111, light can be in light guide body 11 internal delivery.
Fig. 2 is that the light of the utility model embodiment 1 transmits schematic diagram in the leaded light ring shown in Fig. 1.Please refer to Fig. 2, when light enters after light guide body 11a from starting point end S, once touch the wavy structure W of external diameter reflective surface 111, light meeting is because of the non-planar surface of wavy structure W, and formation diffusion.The result that produces diffusion is that light can to all the winds reflect brokenly.Thus, light, in the bright line problem of light guide body 11a, can be improved, and reaches effect of uniform brilliance.But destination terminal E is also identical.In the time that light source is arranged on destination terminal E, destination terminal E is incidence surface.Its principle and process are identical with starting point end S, do not repeat them here.
That above-mentioned leaded light ring 1 can be is ring-like, circular, the shape of a hoof, U-shaped, C shape, regular shape or irregular shape, more than not for limiting the utility model.In addition, in the present embodiment, the section shape of light guide body 11a is square.But the utility model is not as limit.In fact, when the radius-of-curvature of leaded light ring more hour, bright line problem also can be more obvious, the size of wavy structure must be adjusted thereupon.But, due to the size of leaded light ring itself, can make and change according to practical application.Therefore, the utility model does not limit the size of wavy structure.

It should be noted that, getting light mouth 22 is only an example, refers to that optics gets optical pattern design (Pattern), conventionally knows the knowledgeable for having in the art, the form such as groove, salient point that is designed with of getting light mouth 22 when understanding, also has the means such as the degree of depth, height and density to getting the adjustment of luminous energy power.
Fig. 3 B is the stereographic map that is applied to the leaded light ring of the said goods.Please refer to Fig. 3 B, when the light conducting in light guide body 11b, when process is got light mouth 22, light can be got light mouth and be taken out, and the light being removed can be from exiting surface 213 uniformly to external exposure.Thus, except making original pointolite change into area source, more can promote overall light guide effect.In fact, getting light mouth 22 is a kind of microstructures.Compared to wavy structure W, the size of getting light mouth 22 is less.
In addition,, when light source is arranged at the starting point end S of leaded light ring 3, starting point end S is incidence surface; When light source is arranged at destination terminal E, destination terminal E is incidence surface.Because the intensity of light source can be along with far and more more weak apart from incidence surface, therefore in the place far away apart from incidence surface, getting the spacing that light mouth 22 arranges can be closeer, makes the light of whole leaded light ring irradiate out equably, so that more clear, bright and light to be uniformly provided.
Referring again to Fig. 3 A, due to after entering to inject the light of leaded light ring 3 and being got light mouth 22 and take out, convergence of rays combines in the position apart from 1 inch of the diameter D plus or minus of leaded light ring 3.That is to say, if when the diameter D of leaded light ring 3 is 10 inches, the light being emitted via leaded light ring 3, will be gathered in the position apart from 9 to 11 inches, leaded light ring.Therefore,, in the time that the distance d between people and leaded light ring is 9 to 11 inches, it is radiant that user will feel.
In the present embodiment, the light source that leaded light ring 3 adopts can be white light emitting diode.But because the illumination of white light-emitting diodes is stronger, and it is larger to the injury of human eye to be mixed in blue light in white light, therefore also can adopt red light-emitting diode.In the time using red light-emitting diode, in the time that light impinges upon face from getting light mouth 22, will allow face have ruddy effect.
Fig. 3 C is the side view of the leaded light ring shown in Fig. 3 B.Please refer to Fig. 3 C, in the present embodiment, get one of them sidewall wall L of light mouth 22, and accompany angle θ between the normal vector F of exiting surface 213, they are between 40 degree to 60 degree.In certain embodiments, this angle can be 50 degree.

But because light emitting diode is to utilize electronics electricity hole to the compound cold light that sends again, it needn't need be heated to tungsten filament very high temperature as conventional bulb.Therefore, light emitting diode, in luminous process, does not have too many energy resource consumption, has advantages of environmental protection and energy-conservation.But in the middle of light emitting diode, the illumination that belongs to white light emitting diode is higher.Therefore, select white light emitting diode to be used as light source, can reach the less effect of light source number that needs setting.
As mentioned above, because white light has illumination strong, and blue light have injury human eye problem, the light source that therefore the present embodiment adopts can be red light-emitting diode.But, the illumination of red light-emitting diode a little less than, therefore some embodiment still relatively deflection adopt white light-emitting diodes be used as light source.
The problem producing in order to improve above-mentioned use white light emitting diode, in certain embodiments, also can add coloured lid 44 on leaded light ring 4, for example, be red look lid, and envelope the exiting surface of leaded light ring 4.Thus, leaded light ring 4 just can adopt white light emitting diode, not only can increase illumination, can filter again the blue light that human eye is had to injury.
In the present embodiment, exiting surface itself also can utilize alternate manner to form red exiting surface, for example, similarly be the modes such as colouring, spraying, bonding or deposition.Can reach equally use white light-emitting diodes is light source, but the effect that the light that irradiates out from leaded light ring 4 is ruddiness.
In sum, leaded light ring of the present utility model, is provided with wavy structure at the external diameter reflective surface of light guide body towards a side of internal diameter reflective surface.Make to enter the light in light guide body, can, because touch wavy structure, form diffusion, and then can effectively prevent the generation of bright line.It should be noted that only schematic diagram for convenience of description of above-mentioned all figure, not actual true ratio; In fact, wavy structure is that naked eyes can be distinguished hardly.Only have with finger pulp loss and touched, just can feel it and have the feature of wavy structure, visual inspection, still regards it as the annulus of standard.
