Embodiment
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and accompanying drawing
Bright, the content that embodiment refers to not is limitation of the invention.The present invention is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2, Fig. 3, a kind of optical reflector described in the present embodiment, include reflective hood 1 and be arranged at
The light inlet 2 and light-emitting window 3 of reflective hood 1, the light inlet 2 and light-emitting window 3 are circle；The light-emitting window 3 it is a diameter of
Twice of the diameter of light inlet 2；The medial surface of the reflective hood 1 is as reflecting surface 4, the equation of cross section curve 8 of the reflecting surface 4
For：Xj=[3Dtan θ-(2Dj/N) tan θ]/[tan (θ-j θ/N)+tan θ]；Yj=X [tan (θ-j θ/N)]；Wherein, to enter light
One point of contact of mouth 2 is horizontal positioned as origin, reflective hood 1；XjRepresent horizontal direction, YjLongitudinal direction is represented, θ is anti-dazzle
Angle, D be light inlet 2 diameter, N be light-emitting window diameter decile quantity, j ∈ (0, N).Specifically, according to product demand,
Determine the height of anti-dazzle angle θ, the diameter D of light inlet 2, the diameter 2D of light-emitting window 3 and reflective hood 1；Such as Fig. 2, the diameter D of light inlet 2
After being determined with the diameter 2D of light-emitting window 3, the diameter 2D of light-emitting window 3 is carried out N etc. points as needed and forms N number of Along ent 5, then will
Light inlet 2 and the angle steel joint of light-emitting window 3 are connected to form diagonal, and N number of parallel connection lines are done based on Along ent 5 and diagonal
6；Simultaneously anti-dazzle angle θ also decile, its decile quantity is equal with N, bisector 7 is formed, using origin as light source point, according to X and Y
Both relation, anti-dazzle angle θ can switch to radian and be calculated, obtain the intersection points of bisector 7 and parallel connection lines 6 for Xj and
Yj, the N number of intersection point (Xj, Yj) obtained, and by its smooth cross section curve 8 for being connected, drawing reflecting surface 4, wherein, N is bigger, intersection point
It is more；It is worth noting that, the relation of X, Y between the two in surface equation, applicant does not have correlation by the retrieval of early stage
File is recorded, and is that applicant is accidentally obtained by long-term observation and experiment, as long as meeting above-mentioned relation formula, can reach has
Effect by the uncontrollable photocontrol sent by reflective hood 1 to not entering within anti-dazzle angle, such as Fig. 3, the light on reflecting surface 4
Uniformly without dazzling, the free from glare in anti-dazzle angular range, the Integral luminous of reflective hood 1 is soft comfortable, reaches the effect of anti-dazzle
Fruit, realize the effect of black light reflection.
Such as Fig. 2, a kind of optical reflector described in the present embodiment, the N is more than or equal to 10.Specifically, N decile is got over
It is more, then the bisector 7 and parallel connection lines more than 6 passed through, obtained bisecting point is more, is more connect after bisecting point is linked up
The cross section curve 8 near reflex face 4, the cross section curve 8 of the reflecting surface 4 drawn are more accurate.
A kind of optical reflector described in the present embodiment, when the reflective hood 1 is metal material, such as aluminum metallic material,
