Brightness and quantity are then calculated according to the brightness calculation formula of each light fixture in changeover portion 12b and brightness constraints and obtained, in adjustment
While changeover portion 12b brightness of illuminations, the light fixture quantity in changeover portion 12b is reduced, so that reduce changeover portion 12b length, with
Save energy consumption.Further, since redundancy occurs in the reduction of the intraoral illumination demand of tunnel 5, entrance 11a length, so that cause can not
The energy waste of ignorance is, it is necessary to which the length to entrance 11a is adjusted.Utilize the output control signal of stepless dimming controller 15
16, brightness and lamp brightness identical light fixture number in entrance light fixture group 1 in dynamic configuration section light fixture group 2 are reduced, and increase dynamic
Brightness and lamp brightness identical light fixture number in interlude light fixture group 3 in state configuration section light fixture group 2, above-mentioned generation brightness increase, subtracted
Light fixture quantity it is equal, so as to realize the translation of brightness distribution curve 18 in tunnel 5 to the direction of tunnel portal 6, formed new to enter
Mouth section 11b, changeover portion 12b and interlude 13b.
As shown in figure 4, when the ambient brightness outside tunnel 5 is higher or tunnel 5 in vehicle flowrate it is larger when, in tunnel 5
Lighting demand is accordingly improved, in order to ensure the security and comfortableness of driving in tunnel 5, it is necessary to improve each illumination stage in tunnel 5
The brightness of light fixture, and increase entrance 11a length.On the one hand, entrance light fixture is improved by the central controlled mode in loop

The brightness of light fixture in light fixture group 2, wherein the lamp brightness in entrance 11c is kept and the light fixture in entrance light fixture group 1
Brightness is consistent, and the lamp brightness in interlude 13c keeps consistent with the lamp brightness in interlude light fixture group 3, is located at
The lamp brightness in section 12c and quantity are crossed then according to the brightness calculation formula and brightness constraints of each light fixture in changeover portion 12c
Calculating is obtained, and while changeover portion 12c brightness of illuminations are adjusted, increases the quantity of light fixture in changeover portion 12c.In addition, utilizing nothing
Brightness and light fixture in entrance light fixture group 1 in the level output control signal 16 of light adjusting controller 15, increase dynamic configuration section light fixture group 2
Brightness identical light fixture number, and reduce brightness and lamp brightness identical in interlude light fixture group 3 in dynamic configuration section light fixture group 2
Light fixture number, above-mentioned generation brightness increasing, the light fixture quantity subtracted are equal, so as to realize that brightness distribution curve 18 goes out to tunnel in tunnel 5
The translation in 7 directions of mouth, forms new entrance 11c, changeover portion 12c and interlude 13c.
