The working principle of the self-induction light modulation tunnel illuminating system provided for a better understanding of the invention, below in conjunction with Fig. 1,
It describes in detail for the course of work of the concrete application embodiment to self-induction light modulation tunnel illuminating system:
Daytime, if the light of tunnel face and length of tunnel middle position is than suggesting choosing by taking the tunnel of internal 2km long as an example
2 to 3.8 times, be preferably 2.5 times, the relative luminance table prestored is as follows.
Lighting Design recommendation under the 1 sunny sunlight of 2km long tunnel of table
It as shown in table 1, is the Lighting Design recommendation under the sunny sunlight of 2km long tunnel.The entrance distance of the first row in table
Refer to distance of the citing with the sampled point chosen to tunnel face, unit km.Such as 0.05 refers to from tunnel portal 0.05km i.e. 50m
Position, 1km obviously refers to the middle position of the length of tunnel, and 2km then indicates the outlet in tunnel.Second row it is relatively bright
Degree is 100% on the basis of the actual measurement output of tunnel face road surface luminance sensor group, and each sampled point includes optical fibre illumination and LED
Lamp group exports the ratio of the tunnel portal brightness of summation and benchmark.Relative luminance in example as shown in Table 1, at intermediate 1km
It is 40%, i.e., light ratio is 1:2.5 inside and outside tunnel.
Preferably, when the engineering construction of fiber lighting designs works well, the high-power LED light source 4021 in Fig. 1 exists
Daytime will not be re-used as principal light source under normal conditions, and the supplementary function of only well-balanced adjustment, and reply are some extreme
The purposes of special weather.Obviously, the electric energy consumed needed for lighting source when daytime quite will significantly be greatly reduced.
In addition, the sun interts sunlight when being blocked and changing unstable in the clouds, what it is due to sensor array detection is
The total brightness of optical fiber and LED output, it is contemplated that quite stable road surface intrinsic brilliance can be automatically regulated to be under normal circumstances.
It is more than the tunnel of 2km to length, can be set as by the relation table of relative luminance set by table 1 from tunnel face 1km
After 40%, it is always maintained at 40% relatively bright angle value and no longer changes；Also the tunnel middle section after entrance 1km is allowed to do steady appropriate phase
When slow decline.Especially to length, in the Super Long Tunnel interlude of 8km or more, its brightness feasible value can suitably relax.
In table 1, still by taking the tunnel of internal 2km long as an example.If after crossing the midpoint of 1km, the position tunnel exit, that is, 2km
It was found that sunlight is different from the measured value of entry position, it is clear that preferably relatively bright using the measured value of outlet port as outlet section tunnel
Spend 100% value of benchmark calculated.That is, the relatively bright angle value setting in table 1 remains unchanged, only entrance to tunnel middle and tunnel
The calculating reference data value in road middle to outlet section is different.Entrance is to this section of tunnel middle using the brightness of tunnel portal
Value is used as a reference value, and tunnel middle to this section of tunnel exit using the brightness value of tunnel exit as a reference value, guarantee is bright
The flexibility adjusted is spent, certain this more special situation encounters length of tunnel probability when longer can be protected larger
User is demonstrate,proved when passing through long distance tunnel, optimal brightness mitigation and transition can be experienced, provides steady, bright vision
Illuminating effect.
Preferably, the also settable switching module of system, if there is extreme special weather, although on daytime, actual measurement
Tunnel face brightness be lower than the street lamp ground brightness of the road national standard, system will automatically switch to night mode, at this time
General lighting selected value joins table 2 in tunnel.
At night, still by taking the tunnel of internal 2km long as an example.The light of length of tunnel middle position and tunnel face is than suggesting choosing
1.5 to 2.5 times, preferably can be 1.8 times.
Lighting Design recommendation when 2 2km long tunnel night of table
As shown in table 2, be 2km long tunnel night when Lighting Design recommendation.The entrance distance of the first row refers in table
Distance of the sampled point that citing is chosen to tunnel face, unit km.The relative luminance of second row is with tunnel face road surface brightness biography
100% on the basis of the actual measurement output of sensor group, each sampled point includes the tunnel of optical fibre illumination and LED light group output summation and benchmark
The ratio of road entrance brightness.
In example as shown in Table 2, the relative luminance at intermediate 1km is 180%, i.e. the inside and outside light ratio of tunnel middle is
1.8:1.1.95km in table namely separates out mouth there are also 0.05km, and the relatively bright angle value of selection is 130%.
It is more than the tunnel of 2km for length, it is proposed that on the basis of table 2, the tunnel middle section after entrance 1km is always maintained at
The value of tunnel 1km point relative luminance 180%, it is undesirable to do any variation again.Certainly the reason based on energy conservation, can also be to one
The interlude of a little Super Long Tunnels suitably smoothly lowers its relative luminance value on the basis of tunnel 1km point, with section
About energy consumption.
Further, when night, if the brightness value of tunnel portal will be extremely low or even can not survey without street lamp on highway
Amount.At this point, can refer to the national standard of present road street lamp ground brightness, for example the sampled point of 0.2km in table 2 is adjusted to
National standard define in preferred value, and in tunnel remaining put relative luminance can be calculated according to the data of table 2.
Data processing module 20 compares road surface luminance sensor battle array in tunnel based on above-mentioned relative luminance list, analysis
The measured data of column, both tunnel face road surface luminance sensor groups, and environmental information and traffic group of participants can be suitably referred to
Adaptability Evaluation database is finely adjusted, its final output signal controls high-power LED light source 4021 by light-adjusting module 30
Output power, to realize final optimization illuminating effect, the Adaptability Evaluation database mainly increase of environmental information and crowd
Tunnel location due to differences between the south and the north, long-term temperature, relative humidity, the main daily work and rest rule of crowd, to light color
The factors such as the hobby habit of warm different geographical.Comfort Evaluation based on certain amount crowd joins power, colour temperature of light source etc.
Number provides the amendment data of fine tuning, with performance factor of the further lifting system in humanistic care.
As the winter in the north recommends can to use the colour temperature of 2800K, then optional 4500K or 6000K or more of southern summer.Equally
Night, but when the evening lights are lit when people spirit be generally it is still very excited, the spiritual demand with quiet late into the night people is clearly to have
It is distinguished.And luminance sensor at this time basically can not provide any difference, but the present invention can algorithmically according to
Data according to investigations provide the correction factor based on annual time point.For example, relatively bright angle value moderately can integrally be put down at dead of night
Surely turn down, it can be by different periods difference value etc..In addition, the higher order algorithm about colour temperature, spring, summer, autumn and winter can be certain
Different fine adjust automaticallies is continuously done daily to annual in range.
More preferably, when night, vehicle flowrate was less, can increase emotion information that driver independently provides and illuminating effect it
Between interaction, if light can realize slight music beat regular movements to a certain extent, light follows vehicle in long tunnel
Mobile etc. pleasing affect.Even, the variation of the background music that interaction is further added by tunnel and light is mutually echoed, and a kind of
Reasonable fine selection.And can then increase the happy dynamic beat of slight cheerful and light-hearted light in smooth flow on daytime, and vehicle
Flow big traffic more congestion when then implied with the comfort of the slight gradual musicality of light and tranquil psychology as preferred theme.
Further, if detecting tunnel by certain duration such as after 2 minutes at night, still without vehicle pass-through,
Respectively about 150 meters of the standard illuminants of entrance both ends can only be retained, but tunnel middle section is then adjusted light source power is unified after 150m
The small glimmer state for relative luminance about 5%.When detecting will have vehicle to enter tunnel can rapidly smoothly on be adjusted to table 2
In design value.The highway section few to late into the night wagon flow, this improvement will also prolong to a certain extent while saving energy
Long light source life.
