Specific embodiment
The invention will be further described with reference to the accompanying drawing.
As shown in Figures 1 to 3, the present invention includes lamp guide 1, light collimation part, shell 3 and laser handle 4, wherein shell 3
It is sleeved on laser handle 4, and free end is connected with lamp guide 1, in the shell 3, in the luminous end of the laser handle 4
It is equipped with light between 1 end of portion and lamp guide and collimates part, and light collimation part is flush-mounted in the shell 3, laser handle 4
Luminous end project light by the light collimate part after inject 1 end face of lamp guide in parallel.
As shown in Fig. 2, the light collimation part can be a collimation lens 2, or as shown in figure 3, the light is quasi-
Straight part is a parabolic type reflective mirror 5, and the luminous end of laser handle 4 in the middle part of the parabolic type reflective mirror 5 by passing through, the hair
The light that light end is projected injects 1 end face of lamp guide in parallel after the concave reflection of the parabolic type reflective mirror 5.
It is equipped with a fairly large number of optical fiber 7 inside the lamp guide 1, and is emitted position and the incident end face light of end face optical fiber 7
Fine 7 positions non-can correspond, and be random distribution.
The operation principle of the present invention is that:
As shown in figure 11, the light beam that lamp guide 1 in the prior art is emitted has beam energy aggregation in operating distance
Simple optical fiber 7 as shown in Fig. 4~8, first can be analogized to elongated straight glass to illustrate the questions and prospect by the problem of at center
Glass cylindrical body, as shown in figure 4, incident light parallel for α (α ≠ 0) from the incident a branch of incidence angle in one end of the glass cylinder
Line 6, into after glass cylinder, incident ray 6 reflects the refracted light 8 for forming that refraction angle is β, and refracted light 8 can be in glass
It is totally reflected in cylindrical sidewall, forms reflection light 9, as shown in figure 5, if it is the reflection occurred in the plane, light beam
Only can change direction, but body will not change, but as shown in fig. 6, refracted light 8 again it is thin be also with certain diameter,
Unlimited thin light can not be regarded as, so angle of reflection is not at difference on glass cylinder circumferential side wall for above-mentioned refracted light 8
Together, so reflection can not only change direction of beam propagation, light beam can also become the reflected light of diverging from the refracted light 8 of directional light
Line 9, after multiple total reflection, the original parastate of light beam can thoroughly be upset, but its propagation angle changes less, still
It is approximately β, this is just as shown in fig. 7, cause the outgoing beam 10 finally projected from 7 other end of optical fiber to be circle distribution, the angle of emergence
It is approximately α, as shown in figure 8, forming circular hot spot 11.
And as shown in Fig. 9~10, the structure of lamp guide 1 bonds together no several fibers 7 are densely arranged, and
No matter light source is LED or laser, since there are the angles of divergence when light beam projects, and it is more bigger to marginal incident angle α, and due to
7 diameter of optical fiber is very small, and the light beam that each can be penetrated to single optical fiber 7 regards directional light as, so each optical fiber 7
Emergent light spot is all circular distribution, and incident angle α is bigger, and annular radii is bigger, finally the corresponding annulus of all these optical fiber
After the superposition of type hot spot light intensity, form in the operating distance when dentistry lamp guide 1 uses (usually only several centimetres), light intensity exists
The phenomenon that the center point is concentrated, as shown in figure 11.
As shown in Figures 1 to 3, the hair that the present invention shoots out the luminous end of laser handle 4 using a light collimation part
Astigmatism is transformed to parallel collimated light, and allows the vertical lamp guide surface feeding sputtering of the collimated light beam, and such emergent light will have and enter
Penetrate the identical beam pattern of light.
As shown in Fig. 1~3 and Fig. 9~10, lamp guide 1 in the prior art is mostly imaging-type lamp guide, and inside is equipped with
A fairly large number of optical fiber 7, and every optical fiber 7 is emitted endface position and incident end face position is strictly corresponding, so even if laser light
Beam passes through collimationization, and the light beam light distribution after penetrating lamp guide 1 is still consistent with elementary beam, is Gaussian Profile.But this
The lamp guide 1 of invention is emitted the position of end face optical fiber 7 and 7 position of incident end face optical fiber and non-can correspond, and is random distribution,
No matter how incident laser energy is distributed in this way, and after randomization, emergent ray can be approximately to be uniformly distributed.
Since there are many 7 quantity of optical fiber inside lamp guide 1, it is difficult to go out the above-mentioned origin cause of formation, this hair by means analysis such as experiments
Bright is first to carry out parallel laser oblique incidence test to single optical fiber 7, after then carrying out theoretical reasoning and optical software simulation, then is passed through
It crosses actual installation light collimation part to be verified, final certification can effectively solve asking for outgoing beam Luminance Distribution unevenness really
Topic.
