Brightness and quantity are then calculated according to the brightness calculation formula of lamps and lanterns each in changeover portion 12b and brightness constraint condition, are adjusting
While changeover portion 12b brightness of illumination, the lamps and lanterns quantity in changeover portion 12b is reduced, thus reduce the length of changeover portion 12b, with
Energy saving.Further, since the reduction of 5 intraoral illumination demand of tunnel, there is redundancy in the length of entrance 11a, so that causing can not
The energy waste of ignorance needs the length to entrance 11a to adjust.Control signal is exported using stepless dimming controller 15
16, brightness lamps and lanterns number identical with lamp brightness in entrance lamps and lanterns group 1 in dynamic configuration section lamps and lanterns group 2 is reduced, and increase dynamic
Brightness lamps and lanterns number identical with lamp brightness in interlude lamps and lanterns group 3 in state configuration section lamps and lanterns group 2, above-mentioned generation brightness increase, subtract
Lamps and lanterns quantity it is equal, to realize translation of the brightness distribution curve 18 to 6 direction of tunnel portal in tunnel 5, 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 correspondinglys increase, and in order to guarantee the safety driven a vehicle in tunnel 5 and comfort, needs to improve each illumination stage in tunnel 5
The brightness of lamps and lanterns, and increase the length of entrance 11a.On the one hand, entrance lamps and lanterns are improved by the central controlled mode in circuit
Group 1 and interlude lamps and lanterns group 3 in lamps and lanterns brightness；On the other hand, dynamic configuration section is adjusted by the way of single lamp independent control
The brightness of lamps and lanterns in lamps and lanterns group 2, wherein the lamp brightness being located in entrance 11c is kept and the lamps and lanterns in entrance lamps and lanterns group 1
Brightness is consistent, and the lamp brightness in interlude 13c keeps consistent with the lamp brightness in interlude lamps and lanterns group 3, is located at
The lamp brightness in section 12c and quantity are crossed then according to the brightness calculation formula and brightness constraint condition of lamps and lanterns each in changeover portion 12c
It is calculated, while adjusting changeover portion 12c brightness of illumination, increases the quantity of lamps and lanterns in changeover portion 12c.In addition, utilizing nothing
The grade output control signal 16 of light adjusting controller 15, increases brightness and lamps and lanterns in entrance lamps and lanterns group 1 in dynamic configuration section lamps and lanterns group 2
The identical lamps and lanterns number of brightness, and it is identical with lamp brightness in interlude lamps and lanterns group 3 to reduce brightness in dynamic configuration section lamps and lanterns group 2
Lamps and lanterns number, above-mentioned generation brightness increasing, the lamps and lanterns quantity subtracted are equal, 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.
