Embodiment
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.The utility model is carried out below in conjunction with attached drawing
Detailed description.
As shown in Figure 1, Figure 2, Fig. 3, a kind of optical reflector described in the present embodiment, includes reflective hood 1 and is 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 2 diameter of light inlet；The medial surface of the reflective hood 1 is as reflecting surface 4,8 equation of cross section curve 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, YjRepresent longitudinal direction, 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, 2 diameter D of light inlet, 3 diameter 2D of light-emitting window and reflective hood 1；Such as Fig. 2,2 diameter D of light inlet
After being determined with 3 diameter 2D of light-emitting window, 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 3 angle steel joint of light-emitting window are connected to form diagonal, and N number of parallel connection lines are done based on Along ent 5 and diagonal
6；At the same time 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 period
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, 1 Integral luminous of reflective hood is soft comfortable, reaches the effect of anti-dazzle
Fruit, realizes 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, the decile of N 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,
The thickness of the reflective hood 1 is between 0.35-1.5mm.Specifically, thickness is preferably 0.5mm.
A kind of optical reflector described in the present embodiment, when the reflective hood 1 is nonmetallic materials, such as plastic material,
The thickness of the reflective hood 1 is between 0.5-3.5mm.Specifically, thickness is preferably 0.7mm.
A kind of optical reflector described in the present embodiment, the reflecting surface 4 uses specular reflective material, such as mirror-reflection aluminium
Deng, it can make it that the light that reflecting surface 4 reflects forms black light reflecting effect, i.e., from reflector is seen at a distance, the reflector that can't see
Body 1 it is reflective, the illuminator in reflective hood 1 only can be just seen when walking close to reflective hood 1 and looking at reflective hood 1 straight；Separately
Outside, the reflecting surface 4 can also be the minute surface with reflecting effect formed by special process processing.
The above, is only the utility model preferred embodiment, and not the utility model is made in any form
Limitation, although the utility model is disclosed as above with preferred embodiment, but is not limited to the utility model, any to be familiar with sheet
