The meaning of each parameter involved in formula used in the present invention for easy reference, please refers to following table：
Referring to Fig. 1, a kind of areflexia of the low lamp position street lamp dazzle of the elimination provided by first embodiment of the invention is cut
The principle schematic of light method.This method includes：
Section tabula rasa of presetting length is set in the top of low lamp position street lamp according to presetting angle, is looked at straight to avoid driver low
The light-emitting surface of lamp position street lamp eliminates direct glare, and eliminates all reflectors below low lamp position street lamp, to prevent because of reflector
It reflects and generates indirect glare.
Wherein, label 1 indicates that low lamp position street lamp, label 2 indicate to cut tabula rasa, and label 3 indicates that ground, label 4 indicate to drive
Member's eyes.
Further, the length of this section of tabula rasa at least more than：

It should be noted that low level street lamp is different from high-order street lamp, the light projector direction of illumination of high-order street lamp is downward, with road surface
Near vertical, and the light projector direction of illumination of low level street lamp is to the left or to the right, it is almost parallel with pavement of road.Referring to Fig. 2, being
Low lamp position street lighting schematic diagram provided by the present invention.Therefore, the dazzle of low level street lamp comes from two aspects：On the one hand, by
It is required in the light projector direction of street lamp so that the light-emitting surface of street lamp will be not from vertically by being changed to side, street lamp dazzle downwards
Direction, and front street lamp, lateral light-emitting surface is come from, it is horizontal direction dazzle；On the other hand, luminous two after encapsulation
Pole pipe (Light Emitting Diode, LED) patch sends out the scattering light close to 120 degree after once light-distribution.In order to irradiate
Far, further optically focused is needed.Therefore the LED for being generally used for street lamp can use lens to carry out secondary light-distribution, and Fresnel Lenses is
Wherein efficiency is preferably a kind of.Referring to Fig. 3, being Fresnel Lenses concentrating light principles figure provided by the present invention.Fresnel Lenses
Function be by the front lighting convergence for being directed to Fresnel Lenses that light source is sent out be the small almost parallel light beam of beam angle, throw
It is the small almost parallel light beam of beam angle that the function of object plane optical lens, which is by non-frontal light convergence therein,.The two is tied
It closes, constitutes Fresnel --- parabolic lens.Through Fresnel --- after parabolic lens light distribution, the light that LED light source is sent out changes
For the smaller circular light spot of diameter.
Theoretically, the sufficient and necessary condition that paraboloidal mirror sends out directional light be light source be one be accurately located at paraboloid sky
Between focus the infinitesimal particle of volume, the light that any luminous point for deviateing the particle position is sent out by paraboloidal mirror is inevitable
It is not quite identical with primary optical axis, that is, include non-parallel light.Non-parallel light is astigmatism of overflowing, and focus point is remoter, and astigmatism of overflowing is more.And it is real
On border, the infinitesimal light source of volume is not present, and light source volume is bigger, and it is also more to dissipate excessive light.
In addition, road lighting is it is desirable that strip light spots rather than the smaller circular light spot of diameter.It therefore, need to be in luxuriant and rich with fragrance alunite
You --- the micro-structure lens that single-face corrugated shape is placed before parabolic lens make the circular light spot of small diameter in the horizontal direction
It is diffused as strip light spots.But this separate structure can be in Fresnel --- exist between parabolic lens and micro-structure lens
One air space, the interbed can make Fresnel --- and partial dispersion occurs for the directional light of parabolic lens projection, leads to light efficiency
It reduces, while can also precipitate dust.A kind of effective solution approach is, by micro-structure lens and Fresnel --- parabolic lens
It further integrates, is allowed to integration.Such as, ripple is portrayed on inverted Fresnel Lenses surface, is formed and " is inverted Fresnel wave
Line --- parabolic lens ", one-pass molding get the clearly more demarcated strip light spots of dead line, see Fig. 4, are carried by the present invention
The vertical view and side view of " being inverted Fresnel ripple --- parabolic lens " for supplying.
" being inverted Fresnel ripple --- parabolic lens " is used to solve the problems, such as the strip light spots needed for road lighting, but
There is no solve glare problem.Referring to Fig. 5, generating the schematic diagram of the origin cause of formation for dazzle provided by the present invention.It is theoretically parallel
But it can not actually accomplish that the light beam being substantially parallel occurs to dissipate in the outer surface of " being inverted Fresnel ripple --- parabolic lens "
It penetrates, the light of non-master optical axis direction forms excessive astigmatism, and the excessive astigmatism in part can be emitted directly toward the eyes of driver so that driver feels
By strong dazzle.
In fact, all there is insurmountable glare problem in practice with the method for lens light distribution.The key of solution is
Driver is made to realize the dazzle for avoiding occurring in the outer surface of " being inverted Fresnel ripple --- parabolic lens ".Due to overflowing
The angle of astigmatism scattering is very wide, and many positions of automobile driver under steam can all feel dazzle.
In embodiments of the present invention, the mechanism generated according to dazzle, sets in the top of low lamp position street lamp according to presetting angle
That sets presetting length cuts tabula rasa, avoids the eyes of driver from looking at the light-emitting surface of low lamp position street lamp straight, eliminates low lamp position street lamp
Direct glare, and all reflectors are eliminated in the lower section of low lamp position street lamp, avoid generated because of the reflection of reflector it is indirectly dizzy
