Curve.
First exiting surface 113 is made up of the strip arcwall face 1131 and 1132 of two separation.
As shown in Figure 7, it is α to be incident on the angle of the first mirror-lens system 11 from the origin O light sent, according to bar shaped
Luminous flux of light source distribution formula, the then ratio that the luminous flux being incident in the first mirror-lens system 11 accounts for total light flux are；
It is controlled from the light of the first mirror-lens system 11 outgoing by exiting surface 1131 and 1132, in order to allow entrance
Light in the α angular ranges of first mirror-lens system 11 projects target area, it is necessary to adjust the arc of the first fully reflecting surface 112
Degree.First fully reflecting surface 112 is projected as a free curve on the cross section 10 of lens 1, by adjusting the free curve
Control point so that the light being totally reflected from the first fully reflecting surface 112 is incident on strip arcwall face 1131 and 1132.
As shown in figure 8, metope to be divided into different parts, AB/BC/ is in turn divided into from metope top to bottommost
CD/DE/EF/FG sections, length is respectively ab/bc/cd/de/ef/fg to different sections successively.Assuming that metope total height AG=ag.
According to design, the light being emitted from the strip arcwall face 1131 and 1132 of the first mirror-lens system 11 will project
In metope AB and BC.By the cambered surface curvature for adjusting strip arcwall face 1131 and 1132 so that light is incident on metope AB respectively
With BC ends.The ratio that AB and BC ends account for total length isIf according to uniform illuminance, the ratio of length
Bac is the ratio of luminous flux, then bz1=bac.The light being emitted from the first mirror-lens system 11 can be calculated by angle [alpha]
The scope AC of metope need to be radiated at.
According to range of exposures, the camber line of adjustment strip arcwall face 1131 and 1132, so as to from strip arcwall face 1131
It is incident on the light of 1132 outgoing on metope AC.
The strip arcwall face 1131 and 1132 of two separation is made up of the array of regular hexagon arc surface 13311 and 11321.Root
It can be adjusted by the size and height of regular hexagon arc surface 11311 and 11321 according to projection, the effect of the arc surface is light
Line even transition, so as to which obvious lamination will not be produced between section and section, while macula lutea is prevented, make chrominance space one
Cause.
3rd exiting surface 122 of dioptric system 12 is made up of the cambered surface 1221,1222 and 1223 of three separation, three separation
Cambered surface 1221,1222 and 1223 be made up of respectively regular hexagon arc surface 12211,12221 and 12231 arrays.
The angle that the light sent from origin O is incident on dioptric system 12 is θ, according to strip source light flux distribution formula,
The ratio that the luminous flux being then incident on dioptric system 12 accounts for total light flux is。
The light being emitted from dioptric system 12 is controlled by cambered surface 1221,1222 and 1223, in order to allow into folding
The light penetrated in the θ angular ranges of system 12 projects target area, it is necessary to adjust the radian in third reflect face 121.3rd
Plane of refraction 121 is projected as a free curve on cross section 10, and the free curve can be full curve or discontinuous song
Line, in this programme, using discontinuous curve, the discontinuous curve is one to the inclined discontinuous oblique line of metope.And pass through tune
Rectify and improve the control point of discontinuous curve so that the light reflected from third reflect face 121 is incident on cambered surface 1221,1222 and
On 1223.
It is to be emitted in cambered surface 1221,1222 and 1223 from the 3rd exiting surface 122 of dioptric system 12 according to design
Light will be incident upon metope CD, DE and EF ends.Pass through the cambered surface curvature of adjustment 1221,1222 and 1223 so that light enters respectively
Penetrate at metope CD, DE and EF ends.The ratio that CF ends account for total length isIf according to uniform illuminance,
Then the ratio bcf of length is the ratio of luminous flux, then bz2=bcf.It can be calculated by angle [alpha] and angle δ from refraction and be
The light of the outgoing of system 12 need to be radiated at the scope CF of metope.
According to range of exposures, adjust the camber line of cambered surface 1221,1222 and 1223, so as to from these three cambered surfaces 1221,
The light of 1222 and 1223 outgoing is incident on metope CF.
Cambered surface 1221,1222 and 1223 is made up of the circular arc 12211,12221 and 12231 arrays of regular hexagon, according to throwing
The size and height of circular arc 12211,12221 and 12231 of regular hexagon can be adjusted by penetrating effect, and the effect of the circular arc is light
Even transition, so as to which obvious lamination will not be produced between section and section, while macula lutea is prevented, make chrominance space one
Cause.
Second exiting surface 133 of the second mirror-lens system 13 is made up of a cambered surface 1331, and cambered surface 1331 is by regular hexagon
The array of arc surface 13311 forms.
The angle that the light sent from origin O is incident on the second mirror-lens system 13 is δ, according to strip source luminous flux point
Cloth formula, the then ratio that the luminous flux being incident in the second mirror-lens system 13 accounts for total light flux are。
According to design, metope FG ends will be incident upon from the light of the cambered surface 1331 of the second dioptric system 13 outgoing.Pass through
Adjust the cambered surface curvature of cambered surface 1331 so that light is incident on metope FG ends respectively.The ratio that FG ends account for total length isIf according to uniform illuminance, the ratio bfg of length is the ratio of luminous flux, then bz3=bfg.
The scope FG of metope need to be radiated to calculate the light being emitted from the second mirror-lens system 13 by angle δ.
Cambered surface 1331 is made up of the array of circular arc 13311 of regular hexagon, and regular hexagon can be adjusted according to projection
The size and height of circular arc 13311, the effect of the circular arc is uniform light transition, obvious so as to be produced between section and section
Lamination, while macula lutea is prevented, make chrominance space consistent.
The lens 1 are integral type injection molding structure, and material is PC or PMMA.
By embodiment of above, the present invention is not increasing material, in the case of not increasing lens die difficulty of processing,
Realize the polarizing function of lens；And by reasonably designing, the common bottom dark space washed in wall effect is eliminated, makes illumination equal
Evenness brings up to more than 70%；And Lens Design is highly carried out according to wall is actually washed, the practical efficiency of luminous flux is reached 80%；
Dazzle is reduced, is reduced without the light pollution used up.
Same or analogous label corresponds to same or analogous part；
Term the being given for example only property explanation of position relationship described in accompanying drawing, it is impossible to be interpreted as the limitation to this patent；
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not pair
The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.It is all this
