Description
Technical field
The invention belongs to road lighting technical field, more particularly to a kind of compound road lamp of various dimensions.
Background technology
In road lighting, dazzle is always important evaluation index.Dazzle refers to there is brightness scope in the visual field not
Suitably, space or on the time there are extreme brightness contrast so that cause vision that is uncomfortable or reducing visibility to be done
Disturb.
The design of clear stipulaties limitation dazzle and Testing index are threshold delta in CJJ45-2015, and with threshold delta
The upper limit is defined to dazzle for index, an important factor for as evaluation path lighting quality.
Research shows that the method for reducing dazzle is very much, but all there are a contradiction：All measures for reducing dazzle have it
Cost --- the loss of road lamp system light efficiency.Therefore, the essence for reducing dazzle demand is should significantly to reduce dazzle, protect again
Hold specular removal.
In addition, threshold delta regulation is only limitted to form driver " the forward sight dazzle " of forward sight interference, but in fact, road
Also there is other dazzles on road.
It was noticed that in highway, town road and tunnel road lighting, done except forming forward sight to driver
Outside, also there are other two kinds of dazzles for " the forward sight dazzle " disturbed：The dazzle that driver sees in rearview mirror --- " backsight dazzle "
With " side view dazzle ".
" backsight dazzle " lamp source that shows the way is located at forms strong do in driver rear, to driver's observation rearview mirror sight
The dazzle disturbed.The presence of backsight dazzle so that automobile rearview becomes clear a piece of, can not effectively recognize the position of front vehicle
With distance.
" side view dazzle " lamp source that shows the way is located in driver-side, the dazzle disturbed strongly is formed to driver.
Obviously, although there is no clear and definite design specification at present as rear two glare phenomenons caused by street lamp on highway
And Testing index, do not find effective control method yet so far.But (particularly broad way face) is basic under traditional lighting mode
Section is implicitly present in, and also belongs to direct glare category, drives at night to form strong interference for driver.
In addition, the street lamp set for low lamp position, side view dazzle often shows more prominent with backsight dazzle.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of illumination energy effect height and set has a variety of illumination work(
The compound road lamp of various dimensions of energy.
First, the characteristics of low lamp position street lamp dazzle
The lighting system is very sensitive for dazzle.
Visibly different dazzle form and feature is presented with high lamp position street lamp in low lamp position street lamp.
(1) extra small solid angle
Under the conditions of low lamp position, distance of the driver away from front dazzle light source is much larger than distance of the light source away from object, leads
Cause the solid angle that it is observed between the sight of road surface ahead and dazzle light extra small, typically not greater than 10, refer to Fig. 1.Cause
This, though dazzle light source and not directly to driver's eyes irradiate, brightness absolute value is not also high, but as long as front dazzle light source
Reach certain contrast with object brightness, driver still may feel that strong dazzle.This primary optical axis is not pointing at people
The dazzle of eye belongs to the direct glare of non-direct projection.According to threshold delta (dazzle) calculating formula, threshold delta is with light curtain brightness into just
Than, and light curtain brightness is directly proportional to solid angle.Therefore, any reverse illumination component is contributed for threshold delta, particularly
The reverse illumination component of low lamp position contributes bigger for threshold delta.
(2) extra small lamp scale
Under the conditions of low lamp position, street lamp takes road width, this requires street lamp can not possibly the so big body of image height lamp position street lamp
Product, particularly width are limited be subject to tightened up.In 80 meters to the 120 meters most significant sections of this dazzle, since perspective is former
Cause, the low lamp position street lamp scale presented in driver's eye is extra small, is exactly one " bright spot ".Then, in large-scale street lamp application
Commonly used on street lamp lens surface and effective anti-dazzle processing method, such as lens surface frosted, install a section light grid additional, asymmetric
The methods of light distribution, accuses failure.
Just because of above-mentioned two feature, determine for the street lamp set for low lamp position, glare problem is heavy to closing
The problem of wanting.
(3) under low lamp position lighting condition, driver is usually experiencing dazzle most at a distance away from 60~120M of dazzle light source
Big value.
2nd, compound light distribution technology
1st, dazzle is decomposed
For low lamp position lighting system, the dazzle of light source can be analyzed to two parts：
(1) horizontal direction dazzle
Horizontal direction direct light refers to the direct projection for coming from right side road lamp body positive (horizontal direction) that driver feels
Light, see Fig. 2.
(2) vertical direction dazzle
Vertical direction direct light refers to the direct projection for coming from (vertical direction) below the road lamp body of front that driver feels
Light, see Fig. 3.
2nd, baffle plate is cut entirely to calculate
Level, vertical direction direct light for low lamp position street lamp carry out comprehensive analysis discovery, if light source is done level side
To arrangement, due to light projector under street lamp optical axis direction, then only remaining vertical direction direct light needs to eliminate；Conversely, by light source
When doing vertical direction arrangement, only remaining horizontal direction direct light becomes dazzle light source.In fact, no matter low lamp position inversely or just
To lighting system, light source is all to do horizontal direction arrangement, therefore only needs to prevent the direct light of vertical direction.In fact, this is also proper
Just it is the inherent advantage of low lamp position street lamp, high lamp position street lamp has to do the horizontal anti-dazzle light processing with vertical both direction, its
Difficulty can not overcome in current technology.Fig. 4 is referred to, is the computation model of shading baffle.

Calculate, can obtain according to above-mentioned model：
(1) when overhead gage length reaches 360 millimeters, 20 millimeters of the free height ＜ of light source, light source clear height and baffle length
The ratio between be 1/18, be at this time the critical value of vertical direction direct projection dazzle.
(2) under this critical value, driver's moving view point will can't see direct glare and primary event dazzle.
(3) under this critical value, low lamp position is reverse/effective range of orthodromic illumination mode up to 18 meters, i.e. rise ratio is
1/12, it means that using low lamp position it is reverse/orthodromic illumination mode when, 1 meter of the high overlayable effectively irradiation distance of lamp reaches

In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Accompanying drawings and embodiments are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
Only to explain the present invention, it is not intended to limit the present invention.
The embodiment provides a kind of compound road lamp of various dimensions, which includes lamp body and integrates
Multiple illumination subsystems in lamp body.The setting height(from bottom) of the lamp body is less than 1.2 meters, the light projector light of the illumination subsystems
Axis is one or more directions；The illumination subsystems are using optics light distribution and structure light distribution, and the optics light distribution is using freely
Toroidal lens and micro-structure, the structure light distribution is guide-lighting and cut light using lamp body structure, the intelligence control system according to
Its vehicle flowrate received controls the switch of all illumination subsystems with sky brightness situation and runs power, and according to
Weather conditions automatic conversion illumination subsystems.
In the following, it will be explained in the subsystems of the present embodiment：
First, the function of each subsystem, operation principle and design
1st, on low lamp position reverse illumination subsystem：
(1) operation principle：
Traditional road illumination generally uses bat type light distribution, refers to Figure 10.The vertical light intensity of Figure 10 Zhong Yu roads direction of principal axis
The lighting problem having a lot of social connections mainly is solved, refers to Figure 11.
Go the same way in Figure 10 direction of principal axis light intensity can be analyzed to the left, two parts light intensity to the right, corresponding and motor line respectively
The identical direction of illumination in direction and opposite direction (referring to Figure 12) are sailed, direction light intensity dominates the road that driver experiences
Face brightness and spatial vertical illumination, concrete reason look at following analysis：
Light source primary optical axis direction of illumination is identical with motor-driven vehicle going direction to be known as " orthodromic illumination " (referring to Figure 13), conversely
Referred to as " reverse illumination " (referring to Figure 14).It is not difficult to find out, bat type light distribution is by two kinds of high lamp position front illumination and reverse illumination
Mode combines.
A. height of observation, viewing distance and viewing angle are set
Height of observation：It is (right for 1.2M as the observer of automobile driver, the usually height apart from road surface (working face)
Answer trolley)~1.6M (corresponding cart), it is 1.4M that height of observation, which takes median, (IESNA RP-8-2000 are set as 1.45M)；
Viewing distance：Usual viewing distance is 60M to 100M, and it is 80M to take median；
Viewing angle：Usual viewing angleAngle value be divided into between 1.2 ° to 0.45 ° (see 140-2000 ROAD of CIE
LIGHTING CALCULATIONS and《Illuminate measuring method》GB5700-2008, IESNA RP-8-2000 are 1 ° in taking), this
Place's viewing angle takes the median to be
B. under the conditions of regular reflection, the comparison of energy efficiency on two dimensional surface
In regular reflection, since the incident direction of reflected radiation and light source, the size of incidence angle, viewing angle have
Close, therefore, orthodromic illumination mode has visibly different illumination energy effect with reverse illumination mode.Below in two dimensional surface
On the analysis of reflected radiation is carried out to regular reflection road surface to orthodromic illumination mode and reverse illumination mode.
C. the retinal illuminance under positive radiation modality
If EiFor the incoming illumination vector of light source, ErFor illumination by reflected light vector, optical axis Ve, light projector incidence angle is α, the optical axis
Angle between direction and illumination by reflected light vector is that the angle between β, with working face isThenSuch as
Shown in Figure 15.
Direction light intensity can determine that according to distribution curve flux and light projector angle, by cosine law, the point light source can be obtained with calculating
The illumination Ei formed on point.For regular reflection, numerically Er=Ei.According to the subscript convention of this paper1, forward flood lighting
The retinal illuminance E that lower automobile driver direction of visual lines receivesr·eFor formula (1) Suo Shi.
D. the retinal illuminance under reverse radiation modality
Reverse flood lighting such as Figure 16, wherein
The retinal illuminance E that automobile driver direction of visual lines receives under reverse flood lightingr·eFor formula (2) Suo Shi.
1Subscript convention：i：Incident is incident, Ei：Incoming illumination vector；r：Reflection reflects, Er：Illumination by reflected light
Vector；e：Eyes human eyes, Er·e：Component of the illumination by reflected light in driver's human eye's visual axis direction；t:Transversal transverse directions,
Er·tThe cross stream component of illumination by reflected light；v:Vertical is vertical, Er·vThe vertical component of illumination by reflected light.
E. under different flood lighting modes energy efficiency comparison
Using the retinal illuminance that automobile driver direction of visual lines receives as index, the energy under more different lighting systems
Measure effect.When road reflection rate is constant, retinal illuminance and retina brightness are proportional relation.
F. under orthodromic illumination, high lamp position is compared with the energy efficiency of low lamp position
Obtained by formula (1)：
As α → 0, Er·e→0。
Its physical significance is：Street lamp is to the vertical light projector in road surface, equivalent to " high lamp position orthodromic illumination ".
When α → 90 °, Er·e＜ 0.
Its physical significance is：Street lamp is to road level light projector, equivalent to " low lamp position orthodromic illumination ".
G. under reverse illumination, high lamp position is compared with the energy efficiency of low lamp position
Obtained by formula (2)：
As α → 0, Er·e→0。
Its physical significance is：Street lamp is to the vertical light projector in road surface, equivalent to " high lamp position reverse illumination ",
When α → 90 °, Er·e→Er。
Its physical significance is：Light source height, equivalent to " low lamp position reverse illumination ", is observed in sight at this time close to ground
Light radiation EeReach maximum.
Above-mentioned comparison shows, using retinal illuminance as standard, in 4 kinds of lighting systems, and the energy of low lamp position reverse illumination
It is highest to measure effect.
(2) subsystem designs：
In the reverse illumination subsystem, light source setting height(from bottom) is less than automobile driver eye-level display, direction of illumination and place
Track garage direction is on the contrary, irradiation space is the high position underlying space of lamp and road surface, and the no elevation angle scatters, see Figure 17 to Figure 19.
4000K is not higher than for the corresponding demand for improving visibility, the light source of the low lamp position reverse illumination subsystem, colour temperature,
The colour temperature of both sides of the road is higher than the colour temperature of road center.
The operational mode of low lamp position reverse illumination subsystem include normal mode (Chang Quankai in normal lighting time) and
Two kinds of energy saver mode (being dimmed on the basis of normal mode).
2nd, on low lamp position orthodromic illumination subsystem：
(1) function：Road surface background illumination is provided.
(2) operation principle：
Irregular property is presented in the reflection of rough road in street lamp, under rough road conditions, high lamp position reverse illumination,
In four kinds of high lamp position orthodromic illumination, low lamp position reverse illumination and low lamp position orthodromic illumination lighting systems, low lamp position orthodromic illumination side
The road surface average brightness value measured under formula is higher than other lighting systems including reverse illumination.
In the case where lamps and lanterns parameters are consistent, average brightness value is higher than reverse under low lamp position orthodromic illumination mode
The reason for lighting system, is that road surface is coarse-coarse or coarse-smooth pattern, and the light on reverse directive road surface is due to ground
Face particle is relatively rough, and particle protrudes, therefore major part is reflected back, and rough earth particle protrudes, and is reflected into non-directional
Main, cement flooring particle is opposed flattened, based on orienting reflex.As shown in figure 20.
It can be proved that in rough road, when light source is approximately parallel to road surface (low lamp position), direction of illumination with light projector angle
When irradiating road surface ahead with garage's direction identical (orthodromic illumination), highest road reflection can be obtained on pilot's line of vision direction
Brightness.
(3) subsystem designs：
For the demand of corresponding high energy efficiency road lighting, low lamp position orthodromic illumination subsystem is set, in the subsystem, light source peace
Dress height be less than automobile driver eye-level display, and direction of illumination is identical with place track garage direction, and irradiation space is a lamp high position
Put underlying space and road surface, no elevation angle scattering, see Figure 21,22；
It is not less than 4000K for the corresponding demand for improving visibility, the light source of the low lamp position reverse illumination subsystem, colour temperature,
The colour temperature of road center is less than the colour temperature of both sides.
The operational mode of low lamp position reverse illumination subsystem include normal mode (Chang Quankai in normal lighting time) and
Two kinds of energy saver mode (being dimmed on the basis of normal mode).The key issue of low lamp position orthodromic illumination street lamp is to reduce backsight dazzle.
3rd, on low lamp position front illumination subsystem：
(1) subsystem function：Front space illumination is provided.
(2) subsystem operation principle：
The target surface brightness value of description prospect brightness can not possibly be surveyed directly under the conditions of target surface is multifarious
Arrive.Herein, we utilize positively related property between vertical illumination and object brightness, and vertical illumination is bright with object
Degree does " normalization " indirect conversion, so as to obtain calculating the data of object visibility：Brightness, luminance contrast.
The two dimensional model of space illumination and analysis
Figure 23 is referred to, to provide the model of front space illumination：
Ee=Er·cosα·cosβ
Er：Illumination by reflected light vector of the light source in blocking surfaces；
Ee：Component of the illumination by reflected light of blocking surfaces in driver's eye boresight direction；
α：Angle between the incidence angle of light source, i.e. road surface and light source light projector direction；
β：Angle between illumination by reflected light vector and driver's eye optical axis.
Low lamp position front illumination basic principle is：
When α → 0 ° and during β → 0 °, Ee→Er, that is, observe the light radiation E in sighteMaximum will be obtained；Thus scheme
Be not difficult to find out, the direction of visual lines of driver is almost parallel with road surface, for realize identification front obstacle purpose, when light source with
Light projector angle is approximately parallel to road surface (low lamp position), direction of illumination irradiates front space with garage's direction identical (front illumination)
When, the vertical illumination highest of front space, can obtain highest target surface brightness on pilot's line of vision direction；Front is empty
Between vertical illumination be both to help the fundamental component of observation, and produce target surface brightness the reason for.
(3) subsystem designs：
Basic demand for forward direction space illumination is：It should strengthen the brightness between road surface background and front obstacle to bear pair
Than degree and Chromatic Contrast.
On the other hand, the distribution gradient of rational vertical illumination, and energy-efficient institute are required.
The illumination vertical gradient of forward direction space illumination subsystem is distributed see Figure 24.The light distribution design of lamps and lanterns should also be
3 meters of above sections provide appropriate illumination, with the top profile of profit identification oversize vehicle.Vertical direction is divided into three illuminations
Area：
Cover area：Apart from 0~1.5 meter of pavement-height, major function is irradiation road surface and car；
Transition irradiated region：Apart from 1.5~3 meters of pavement-height, major function is irradiation oversize vehicle rear vehicle；
Marginal irradiated region：Apart from 3~5.3 meters of pavement-height, major function is display oversize vehicle profile.
Cover area is the key area of front illumination, it is desirable to has higher vertical illumination, transition irradiated region takes second place, side
Border irradiated region is minimum.The specific requirement numerical value of three illumination subregion illumination, need to be determined by way of experiment test.
The requirement of front illumination subsystem for undertaking space illumination is：Using (simple herein with high light chromaticity matter
Turn to compared with high-color rendering, non-excessive colour temperature), with background light source (herein be irradiation road surface light source) have certain aberration
Light source, the illumination for providing space should have brightness to bear reduced property.
The light source of front illumination subsystem, colour temperature is higher than reverse illumination component, but is less than 5500K, and colour rendering index is more than 70,
For height near automobile driver eye-level display, direction of illumination is identical with the garage direction in place track, (refers to Figure 25, figure
26)；Operational mode includes normal mode (standard-sized sheet at times in normal lighting time) and energy saver mode (normal mode basis
Upper light modulation).
4th, on low lamp position transverse illumination subsystem
(1) subsystem function：Extreme weather illumination is provided.
(2) subsystem work principle：
Under the extreme weather conditions such as rain, mist, haze, cigarette, the reason for efficiency of motor vehicle far-reaching lamp is significantly lower is in machine
It has accumulated the aerosol particles group of a large amount of suspensions in air in front of motor-car.Before this causes one side part directive motor vehicle
