| 3 | Low colour temperature | Color Snazzi degree | Sense of direction |
The technical solution that will specifically introduce in the embodiment of the present invention below, please refers to Fig.1 and Fig. 2, Fig. 1 are the present invention the
A kind of floor map for bad weather accommodation road lighting system that one embodiment provides, Fig. 2 is first embodiment of the invention
A kind of diagrammatic cross-section of the bad weather accommodation road lighting system provided.The bad weather accommodation road lighting system is in energy
Degree of opinion is opened when being less than default fiducial value, which is more than or equal to default ratio in visibility
It is closed during compared with value.
And the lamps and lanterns of the bad weather accommodation road lighting system are by the way of low lamp position, distribution and transverse illumination
Mounted on both sides of the road, to improve the edge Snazzi degree of human eye, Stereoacuity and color Snazzi degree, realize that bad weather is special
The dedicated illumination mode of roadway lighting system.
Further, which using radiating visible light and radiates non-visible light signal
Light source, and visible light source has low colour temperature, high-color rendering and high penetrating power, non-visible light signal is steady or pulse, wears
Saturating power is more than the non-visible electromagnetic signal of visible ray.
Further, the mounting height of the lamps and lanterns of the bad weather accommodation road lighting system is low to realize less than 1.4 meters
Lamp position is installed.
Further, the clipping room of the lamps and lanterns of the bad weather accommodation road lighting system is away between being 2 meters to 8 meters, with
Realize distributed installation,
Further, the light projector axis direction of the lamps and lanterns of the bad weather accommodation road lighting system realizes it with driver
Between angle be 80 degree to 100 degree between, to realize transverse illumination.
It should be noted that the lamps and lanterns of the bad weather accommodation road lighting system are opened under severe weather conditions,
It can be opened under the conditions of normal weather.Severe weather conditions include but not limited to heavy rain, dense fog, heavy snow and heavy fog haze, and severe
The standard of weather is low visibility.The lamps and lanterns of the bad weather accommodation road lighting system use low lamp position, distribution and transverse direction
The mode of illumination be mounted on both sides of the road, be because：
1), during the turnpike driving of closing, driver only needs to observe road surface and road ahead situation, without
It needs to observe the situation other than road.According to the mounting means of traditional high-order street lamp, can be formed largely in upper pavement surface
Invalid illumination region, and there is a large amount of invalid light in effective lighting region and lead to.Under severe weather conditions, due to water
The absorption and scattering of drop, crystal ice granule, particulate etc., the luminous flux that can reach human eye are even more very little.It please refers to
Fig. 3 reaches the schematic diagram of driver's eyes for light in the present invention after barrier reflects.The light of lamps and lanterns radiation is in air
Middle propagation, encounters barrier back reflection, and reflected light spreads into automobile driver eyes in air.Due to existing in air
Particulate so that when light is propagated in air, can be absorbed and scattered by particulate, eventually arrive at driver's eyes
Luminous flux greatly reduces.
Light can decay when passing through air, and attenuation model can be expressed as：
Wherein, E is object brightness, EdFor light-source brightness, λ represents the wavelength of light, and β (λ) represents light scattering power, and d is
Target is away from observer's distance.
From attenuation model as can be seen that when distance of the target away from observer is bigger, light attenuation is stronger, shows more
Particulate is scattered light.
The lamps and lanterns of the bad weather accommodation road lighting system are installed by the way of low lamp position, and mounting height is less than 1.4
Rice, while the invalid light of reduction is logical, since the path of light to road surface is shorter, the light absorbed by particulate is also less,
And low position lighting can increase more luminance differences in target area, and driver is helped to build a more complete object three-dimensional mould
Type, auxiliary judgment position relationship ensure necessary braking distance.
2), under severe weather conditions, driver will not only observe front road conditions, avoid bumping against with front truck, Hai Yaokan roads
The street lamp post on side or along line index, prevents from going out road surface, and traditional high pole street lamp is at a distance of remote, and continuous arrangement so that normal
It is preferable to the vision guide of driver under weather, i.e., with preferable inductivity, and under severe weather conditions, due to high bar
The illumination that the light of street lamp radiation reaches road surface is inadequate so that continuity mark is lost between lamp stand, causes to lose inductivity.
The lamps and lanterns of the bad weather accommodation road lighting system are installed using distributed mode, and clipping room is away from being 2 meters to 8
It between rice, is installed with reference to low lamp position so that still there is inductivity under severe weather conditions.
3), under severe weather conditions, driver cannot finely recognize the barrier on road surface.Whether identification barrier is deposited
, it is only necessary to confirm the edge of barrier.After observing that front obstacle exists, further judge and front obstacle
Distance increases the edge contour contrast of front obstacle.That is, in certain distance, under the premise of ensureing that transitional region is constant, lead to
Crossing increases the luminance difference in transitional region to promote the peripheral vision of front obstacle.
When visible ray medium molecular across haze grain, it may occur that scattering and absorption, scattering coefficient is with absorbing system
Number is respectively：
Ksca=Csca/Sp, Kabs=Cabs/Sp
Wherein, KscaFor scattering coefficient, CscaLead to for haze KPT Scatter power and the general power for the light for being incident to the particle
The total ratio of metric density, SpDuring for the particle incidence of visible ray face, in the projected area of the plane particle in vertical light wave direction,
KabsFor absorption coefficient, CabsThe ratio total with the total power flux density for the light for being incident to the particle for haze particle absorption power
Value.
By scattering coefficient and absorption coefficient it is found that when the angle between incident light and pilot's line of vision is close to 90 degree, laterally
The light of radiation leads to, and can driver be scattered influence caused by haze particle along the sight of road direction and is preferably minimized.
The lamps and lanterns of the bad weather accommodation road lighting system are installed by the way of transverse illumination, make the light projector axis of lamp
Between angle between direction and pilot's line of vision is 80 degree to 100 degree.It is effective to strengthen the whole luminance difference with background of vehicle,
Driver is allowed to experience the presence of front vehicles, is warned.Wherein, between the light projector axis direction and pilot's line of vision of lamp
For angle closer to 90 degree, vehicle is whole bigger with the luminance difference of background.
Further, which using radiating visible light and radiates non-visible light signal
Light source, and the visible light source have low colour temperature, high-color rendering and high penetrating power, be because：
1), visibility caused by severe weather conditions is low and night it is dark caused invisible in the presence of difference fundamentally.
Severe weather conditions are happened at daytime or night, and the illuminating effect of conventional road lamp can have a greatly reduced quality, light source directive machine
The incident light of motor-car front space can form white wall phenomenon, and part reflected light is by water droplet, crystal ice granule, the aerosol particle in air
The absorption and scattering of son etc. cause driver's road ahead visibility low, particularly, using traditional road of LED source
Lamp can not enough make light become extremely faint under severe weather conditions because of penetrability.And under severe weather conditions, road roadside
The identification of boundary, traffic information plate, front vehicles etc. is extremely difficult.
The bad weather accommodation road lighting system is using radiation with the visible of low colour temperature, high-color rendering and high penetrating power
Radiant since light source has high penetrating power, can improve visibility of the object under severe weather conditions, and the light source has height
Colour rendering so that road edge, barrier and traffic information plate etc. are more clear with ambient enviroment colour difference, even if in severe day
Under the conditions of gas, can still be formed in driver's brain more clearly influences, and improves drive safety.
2), the bad weather accommodation road lighting system uses the light source of radiation non-visible light signal, and the non-visible light
Signal is the non-visible electromagnetic signal that steady or pulse, penetration power is more than visible ray, which is convenient for by machine
Detector in motor-car off-track detection system receives, and is merged using human eye vision with machine vision cross check, height, to motor-driven
The yaw of vehicle under steam is warned and is controlled.
In addition to this, which can improve edge Snazzi degree, the Stereoacuity of human eye
With color Snazzi degree, be because：
Under severe weather conditions, the vision mode variation of driver's concern is：Front whether there are obstacles, that is, warn
Sense；Approach relationship or renunciation with front obstacle, i.e. distance perspective；The position relationship of vehicle and road edge, i.e., just
To sense.And exist between warning sense, distance perspective, sense of direction and edge Snazzi degree, Stereoacuity, color Snazzi degree and correspond
Relationship.Therefore：
1), sharpness of vision is made of two factors of resolution ratio and object edge profile contrast.Sharpness of vision is equal to transition region
The ratio of the brightness change of domain both sides and the change in location of transitional region.Under severe weather conditions, driver judges that front is
No there are barrier is basic demand that driver sees barrier, and edge is promoted under front obstacle a certain distance and is regarded
Feel, as under the premise of transitional region is constant, increase transitional region luminance difference, it is corresponding to increase edge Snazzi degree.
Luminance contrast is to characterize the physical quantity of the luminance difference between object and its background.Visibility is human eye to object
The complexity of the presence of body, shape or size identification sees the readability of object.The meter of luminance contrast and visibility
Calculating formula is respectively：
Wherein, C is represented depending on seeing the luminance contrast between target and its background, LtRepresent the brightness depending on seeing target, LbIt represents
Background luminance depending on seeing target, Δ L represent that depending on seeing the luminance difference between target and its background V represents the visibility depending on seeing target,
C0Represent the luminance contrast between the target and its background, i.e. critical luminance contrast during depending on seeing that target is just visible.
And critical luminance contrast C0Calculation formula be expressed as：
Wherein, Lt0Represent the background luminance of target during depending on seeing that target is just visible, LbIt represents depending on seeing that target is just visible
When the target background luminance, Δ L0Represent the threshold luminace difference between the target and its background during depending on seeing that object is just visible.
In addition, vision efficiency can show factor (CRF), disability glare by relative contrast sensitivity function (RCS), comparison
Factor (DGF) and the instantaneous factor (TAF) etc. that adapts to provide, and uniformly represented with the horizontal VL of visibility, it is seen that spend horizontal calculating
Formula is expressed as：
Wherein, VL, Δ L and Δ L0Meaning it is identical with the meaning of above description.
Therefore, it can be deduced that：
Wherein, the meaning of each parameter occurs in the parameter explanation of other above-mentioned formula in formula, and which is not described herein again.
It can be obtained from above-mentioned formula, it is seen that degree V and luminance contrast C direct proportionalities.When the size depending on seeing target
With the timing of illumination one, show this depending on the critical luminance contrast C of seeing target0Centainly.Brightness contrast depending on seeing target and its background
It is bigger to spend C, then, it is seen that degree V is bigger.
The lamps and lanterns of this bad weather accommodation road lighting system are installed by way of low lamp position and transverse illumination, can be strengthened
Depending on seeing the luminance contrast between target and its background, the edge Snazzi degree of object is improved.
2), Stereoacuity is that the organs of vision perceive the resolution of surrounding objects distance, the depth, height three-dimensional space position
Ability.Stereoacuity can be divided into sectional perspective and regard and whole stereopsis, and sectional perspective is depending on being to be formed parallax with a small amount of lines
Primitive, comprising parallax information amount it is few, be a kind of very extensive rudimentary stereopsis function, and whole stereopsis is with a large amount of
Be concealed with parallax information point form parallax primitive, comprising parallax information amount it is big, directly cerebral cortex complete to parallax
Information is by the transformation of 2 d-to-3 d, therefore whole stereopsis is a kind of fine advanced stereopsis function.Therefore, it directly presents
The a large amount of pixel for having parallax information, it will help to promote driver's Stereoacuity, and then be more easy to judge and front barrier
Hinder the approach relationship between object or renunciation, also illustrate under severe weather conditions simultaneously, the vision mould of driver's concern
Distance perspective and Stereoacuity are corresponding relationships in type.
The lamps and lanterns of this bad weather accommodation road lighting system are installed using distributed mode, with reference to the height colour developing of radiation
Property light source increases the pixel of more dark or bright (with respect to background luminance) in target area, is ensureing that front obstacle has
On the basis of one higher edge Snazzi degree, Stereoacuity is greatly promoted, the big brain-capacity of driver is made to build one more completely
Object threedimensional model, so as to the approach relationship or renunciation of auxiliary judgment and front obstacle.
3), color Snazzi degree is based on luminance difference, and any colour has the brightness value of oneself, with International Commission on Illumination
(French：Commission Internationale de L ' Eclairage, CIE) international standard based on standard is specific
Transformational relation of the color space to brightness is defined, according to this definition, any colored numerical value represented can be directly turned
It is changed to brightness value.
This bad weather accommodation road lighting system uses the visible light source for radiating low colour temperature, can utilize part light source,
It is photochromic to change light source so that the identification difficulty of front obstacle is declined, and greatly promotes the color Snazzi degree of driver, so as to
A clearly boundary image is formed in the brain of driver, restores warning sense, distance perspective and the sense of direction of automobile driver,
Reconstruct the human eye vision ability of driver.
