After the light that can originally project except regulation beam angle is deflected, these light is made to tend to horizontal direction injection, in this way,
Stray light will not project spot area again, so as to avoid glare effects caused by stray light.
Technical solution of the present invention is described in detail with reference to the accompanying drawing.
With reference to Fig. 3, the present invention provides a kind of with light unit, including light source 2, light source substrate 3 and lens body 1, the light
Source 2 is fixed on the light source substrate 3, and the lens body 1 covers at the light source 2 and, institute fixed with the light source substrate 3
Lens body 1 is stated along its rotary shaft in rotational symmetric shape, the lens body 1 includes the center exit portion 15 continuously to connect and dizzy
Light limiting unit 7, the dazzle limiting unit 7 is around the center exit portion 15, and the dazzle limiting unit 7 is for sending out the light source
Out, except beam angle is greater than the light deflection to the second beam angle threshold value of the first beam angle threshold value, wherein second light beam
Angle threshold value is greater than the first beam angle threshold value.
Specifically, the lens body 1 is axial symmetry rotary body, and the lens body 1 includes center exit portion 15 and dizzy
Light limiting unit 7, the dazzle limiting unit 7 are incorporated in the peripheral side of the center exit portion 15, and the two can be integrally formed, such as logical
Overstretching squeezes integrated molding.
The light that the light that Fig. 1 issues combined with Figure 1 and Figure 2, for light source 2 in the prior art is projected through lens body 1 is propagated
Schematic diagram, Fig. 2 are that light corresponding to a kind of specific 1 structure of lens body of the present invention propagates schematic diagram, the first beam angle threshold
Value and the second beam angle threshold value can be set according to required distribution curve flux, 7 pairs of light of center exit portion 15 and dazzle limiting unit
Beam angle can be greater than except the light deflection to the second beam angle threshold value of the first beam angle threshold value by the refraction angle cooperation of line.
For example, when the first beam angle threshold value is set as 60 °, it is provided by the invention when the second beam angle threshold value is set as 85 °
Lens body 1 can be deflected by the emergent ray that dazzle limiting unit is greater than 60 degree to beam angle, make these emergent rays
Beam angle increases to 85 ° or more, and the light that beam angle is 85 ° or more will no longer project in spot area, therefore, this part

In, spurious rays refer to that beam angle is greater than the light of the first beam angle threshold value.
Below in a manner of multiple embodiments, illustrative explanation is carried out to the specific constructive form of the dazzle limiting unit 7:
The first embodiment are as follows:
The dazzle limiting unit 7 includes incidence surface and dazzle limiting unit exit facet, and the incidence surface and the center are emitted
Face is opposite and the annular groove to form that longitudinal section is in irregular that continuously connects, the incidence surface will be projected from the center exit facet
, beam angle be greater than the light deflection of the first beam angle threshold value to the dazzle limiting unit exit facet.
With reference to Fig. 4, there is an annular groove between center exit portion and dazzle limiting unit, the annular groove by the center exit facet and
The incidence surface of the dazzle limiting unit connects to being formed.Trapezoidal annular groove, so that center exit facet is not parallel to dazzle limiting unit
Incidence surface, therefore, the light greater than the first beam angle threshold value projected from center exit facet can enter light by dazzle limiting unit
Face increases unirefringence, it is, some light that the annular groove issues light source can sequentially enter by the light of lens body
Face, center exit facet, the incidence surface of dazzle limiting unit and dazzle limiting unit exit facet are penetrated, from the dazzle after four refractions
Limiting unit exit facet projects.
In the present embodiment, it is preferable that the incidence surface and dazzle limiting unit exit facet of the dazzle limiting unit 7 continuously connect shape

Deng the present invention is not especially limited this.
Light distribution schematic diagram as shown in connection with fig. 2, when injecting lens body 1 from air due to light, incidence angle is greater than folding
Firing angle；And on the contrary when light injects air from lens body 1, incidence angle is less than refraction angle, therefore, when the light that a light source issues
After above-mentioned four times refractions, the direction of propagation will turn line to 3 lateral deviation of light source substrate, it is, the beam angle after its deflection will
Much larger than its initial beam angle.
And by accurately calculating the incidence surface that can determine center exit facet and dazzle limiting unit 7 and dazzle limiting unit exit facet
Angular compliance relationship, and the angular compliance relationship between three be not it is unique, as long as can satisfy light refraction angle
It is required that angular compliance relationship.
Another embodiment are as follows:

Portion 7 processed is set as the ring body that longitudinal section is in prism-frustum-shaped, certainly, the table top of the ring body not necessarily plate with the light source substrate 3
Face is parallel, can also be inclined-plane, such as on the basis of the rotary shaft of lens body 1, from the side close to rotary shaft to far from rotation
The side of shaft is in tilt from top to bottom.
In the present embodiment, it is greater than when the light that light source issues calculates acquisition beam angle according to the shape trend of center exit facet
When the first beam angle threshold value, this some light can be projected from dazzle limiting unit exit facet, and work as the slope of dazzle limiting unit exit facet
When spending the gradient corresponding with the tangent line of the table top joint less than center exit facet, the dazzle limiting unit exit facet can be light
Line provides bigger refraction angle, that is to say the beam angle of increasing light.
The table surface height that dazzle limited section 7 can be determined according to preset first beam angle threshold value that is to say which light determined
Line is projected from center exit facet, which light is projected from dazzle limiting unit exit facet, and as the slope of dazzle limiting unit exit facet
Degree then can carry out calculating determination according to the second beam angle threshold value, that is to say according to required beam angle degree of deflection and determine.
