Description
Technical field
The invention belongs to road lighting technical field more particularly to a kind of light chopping low level roads big and anti-dazzle away from high ratio
Lamp and preparation method thereof.
Background technique
There are two big common problems for existing low level street lamp technology: first is that away from height than too low, the result is that light projector is excessively close, in road
Entreated it is dark, be unable to reach CIE2010 and CJJ45 requirement；Second is that having stronger dazzle, the result is that threshold exponent TI is more than
CIE2010 and CJJ45 standard.Refer to the ratio between lamps and lanterns projection light maximum distance and lamps and lanterns suspension height away from height ratio.I.e. street lamp is farthest
The ratio between effective lighting distance and lamp installation height.
Conventional low lamp position street lighting mode, by low power LED light source be directly installed on road guard, isolation strip,
On anti-collision wall, general mounting height is between 0.8 meter to 1.5 meters, from both sides of the road to light projector among road surface.
The lamp position of low level street lamp reduces, and partially overcomes biggish invalid area of illumination existing for high lamp position lighting method and asks
Topic.But since light source power density is excessively high, this lighting method the biggest problems are that close to street lamp runway driver's meeting
Feel strong dazzle.
In order to reduce dazzle, street lamp must force down the crevice projection angle of light, to reduce the stray light for entering driver's eyes.But it drives
The person of sailing still can look at the light-emitting surface of street lamp straight, though dazzle is weakened, but still interfere to driver.Due to the projection of street lamp light
Angle is depressed, and most of light is projected on the road surface of street lamp, and the inner lane in broad way face can not be illuminated, and be caused
Road two sides are excessively bright, road-center but without illumination the phenomenon that, be not able to satisfy through street basic road illumination requirement.
2013, Chinese patent ZL201320002812.0 disclosed a kind of LED low level street lamp, and lamps and lanterns are placed in driver
Sight by the light distribution of lens hereinafter, designed so that the necessary brightness of road surface acquisition, limits dazzle in a manner of illuminating downwards.For
Make the directive ground that its light is more, while angle can be adjusted flexibly, it is asymmetric to be equipped with refraction angle or more in front of LED light source
Lens.
Analysis shows the lighting method has two: first is that whole illumination concentrate on 1.2 meters of road surface height hereinafter,
Without upward transition region, contrast is excessive, and comfort is poor；Second is that this method can not really eliminate dazzle, driver remains to see and come from
In the dazzle of front side lamps and lanterns " light-emitting surface ", as shown in Figure 1.
Further, since low level street lamp is irradiated from both sides of the road to center, since cost and mounting condition limit, street lamp it
Between spacing be generally 3 meters to 8 meters, in order to illuminate road-center as far as possible, the beam angle of street lamp cannot be big, leads to serious zebra
Line, as shown in Figure 2.
Road-center road surface is illuminated, low level street lamp should be not less than 10 away from high ratio.Existing street lamp optics light distribution technology
The shielding angle of standard requirements half optical path lamp is not less than 15 °, and corresponding cutoff angle is 75 °, and shielding angle makes away from high ratio most very much not
More than 4.0, as shown in Figure 3.
Though low level street lamp unprotect angle requires, the principal contradiction in terms of light distribution is to increase light projector distance and inhibits dizzy
Light.Reducing street lamp dazzle must be using a section light technology, it means that whole light effect will lose, and light projector distance shortens, up to not
To the brightness demand of road center part；For the brightness demand for meeting road center part, be bound to light source power to be increased, this meeting
Street lamp light-emitting surface is caused to brighten, dazzle increases again.Therefore, conventional low level street lamp away from high ratio, although being greater than the high pole line of tradition
Lamp, but also it is usually no more than 6.0.Away from height than low reason, be existing street lamp, no matter high-order or low level street lamp, be all made of list
One (optics) light distributing method, including primary, secondary or even optics light distribution three times, are limited by the refraction angle of lens, such as Fig. 4 institute
Show.
The brightness demand that road center can not be met simultaneously is proved by a host of facts using the result of single light distribution and is prevented
The common prescription of dazzle.
Road center cannot be bright to meet road center using simple increasing lamp power without illumination way to solve the problem
Degree requires because this to will lead to dazzle strong.Therefore, increase away from height than being that low level road lamp light distribution technology first has in research
Hold.

≤tg1d0；
It can obtain: h0/d0=0.010 < tg1.
The upper section of vertical range h0 value range between the down contour point of electro-optical device and the up contour point of lower section of electro-optical device
Specific calculating process is as follows:
Pilot's line of vision and horizontal angle are α, because incidence angle is equal to angle of reflection, then primary optical axis and horizontal folder
Angle be also be α.The upper down contour point P (x for cutting tabula rasa3, y5) it is not higher than pilot's line of vision, i.e. point P (x3, y5) highest point and drive
Member's sight intersection.Down contour point P (x of the farthest irradiation distance of primary optical axis by upper section tabula rasa3, y5) restrict, farthest irradiation distance master
Down contour point P (the x of optical axis light and upper section tabula rasa3, y5) intersect, i.e. pilot's line of vision and primary optical axis intersects at point P simultaneously
(x3, y5).Under cut tabula rasa up contour point Q (x2, y6) be not less than pilot's line of vision, i.e. when light-emitting window h0 obtains maximum value, point Q (x2,
y6) intersect with pilot's line of vision.
Because the upper value range for cutting tabula rasa is 0.05m≤a≤1.0m, the value range of lower section of tabula rasa be 0.0m≤b≤
0.8m, works as a=1.0m, when b=0.0m, h0Obtain maximum value.
So:
h0Value range isThe value range of α is 0 ° of α≤4 ° <, above cuts the value model of tabula rasa a
It encloses for 0.05m≤a≤1.0m, the value range of lower section of tabula rasa b is 0.0m≤b≤0.8m, work as a=1.0m, when b=0.0m, h0
Maximum value is obtained, so h0Value range isThat is -0.07m≤h0≤0.07m。
Further referring to Fig. 7, using the vertical line between point K and horizon as symmetry axis, where obtaining pilot's line of vision
