Instance
This instance relies on three, capital pearl trunk lines of national expressways around Guangzhou around the city key project-tunnel, leading mountain of highway eastern section (Zhujiang River Huangpu, Guangzhou bridge), design highway tunnel illumination system.Tunnel, tap mountain is the longest at present domestic two-way separate type eight track highway long tunnels.Tap mountain Tunnel Design road speed: V=100km/h=27.78m/s; Table 2 is seen in illumination Design brightness: (4000cd/m2 is got in hole external environment brightness) leading mountain tunnel illumination is divided into five sections by the driving direction of advance, i.e. entrance, changeover portion I, changeover portion II, interlude, outlet section.
With reference to Fig. 1, Fig. 1 is that the light fixture of highway tunnel illumination system in the prior art is arranged sketch map.Wherein, 11 is that ceramic gold-halogen lamp, 12 is fluorescent lamp, and 13 is track clearance, and 14 is the tunnel center line.θ
1Beam angle for ceramic gold-halogen lamp.In this example, beam angle θ
1Be 46.8 °, the beam angle of fluorescent lamp is 51.8 °.
Here, the notion of beam angle is made an explanation.Said beam angle is: on one of normal beam center line plane, luminosity equals the angle between two directions of 50% maximum luminosity.
With reference to table 1, table 1 is in the prior art, prior art design brightness of illumination value.
Table 1 prior art design brightness of illumination value
With reference to table 2, table 2 is a design light fixture quantity in the prior art.
Table 2 prior art design light fixture quantity
| Sequence number | The light fixture kind | Power | Unit | Quantity |
| 1 | Fluorescent lamp | 2 * 54W three primary colours double tube fluorescent lamp | Cover | 2810 |
| 2 | Ceramic gold-halogen lamp | TUN15M8ASY type 150W | Cover | 120 |
| 3 | Ceramic gold-halogen lamp | TUN15M8ASY type 150W | Cover | 1028 |
In addition, the conservation measures of tunnel illumination system is except reasonable selection of design parameters, and it also is the major issue of lighting energy saving that science is selected electric light source for use.Table 4 is performance parameters of several kinds of main lighting sources in the existing highway tunnel.
Light source performance table in the table 3 existing highway tunnel
| The light source kind | Light efficiency (1m/W) | Colour rendering index (Ra) | Colour temperature (k) | Average life span (h) |
| High-pressure mercury lamp | 100-120 | 23/60/85 | 1950/2200/2500 | 24000 |
| Low-pressure sodium lamp | 200 | 23 | 1750 | 28000 |
| Metal halide lamp | 75-95 | 65-92 | 3000/4500/5600 | 6000-20000 |
| High-pressure sodium lamp | 50 | 45 | 3300-4300 | 6000 |
| Compact fluorescent lamp | 60 | 85 | Complete series | 8000 |
| Electromagnetic induction lamp | 55-70 | 85 | 3000-4000 | 40000-80000 |
| White LED lamp | 107-114 | 90 | 6400 | 100000 |
At present, the highway tunnel illumination light source can be divided into two types of directional light and scattered lights.Except led light source, other light sources all is a scattered light.Source efficiency is that light source is selected one of index of being concerned about most, and it can be described with luminous efficiency and two parameters of colour rendering.The factor that influences luminous efficiency mainly contains the maintenance coefficient of every watt lumen number, light fixture, the usage factor of light fixture and the additivity of light efficiency.Led light source light efficiency and high-pressure mercury lamp are suitable, are the highest; But LED is a directional light, and its light fixture usage factor is 0.8-0.9, and the light fixture usage factor of other light sources has only 0.4-0.5.Therefore, even under the identical situation of the lumen per watt number of light source, adopt led light source also can practice thrift 1 times electric energy than the employing other light sources.
Simultaneously, higher colour rendering also is one of reason of selecting led light source.The tunnel is strengthened the section illumination and is belonged to the photopic vision category; By " standard for artificial lighting design of industrial enterprises " (GB50034-92) and the table " illuminating engineering design manual; 1984 " relation between illumination and the colour rendering index Ra, after can obtaining considering colour rendering, section lighting illumination intensity conversion coefficient is strengthened in the tunnel.
The conversion relation of section light source colour rendering index and illumination is strengthened in table 4 tunnel
| Average colour rendering index | 100 | 90 | 80 | 70 | 60 |
| Conversion coefficient | 0.625 | 0.744 | 0.881 | 0.962 | 1 |
Table 4 means if it is 60 that the light source colour rendering index is adopted at the hole, if changing light source into colour rendering index is 80, then the brightness demanding criteria should take advantage of 0.881.Result of study to the relation of illumination and colour rendering shows that from the visual psychology angle, under equal illumination, the light source that colour rendering is good is brighter sensuously than the light source of colour rendering difference.Therefore, when adopting the higher light illumination of colour rendering index, it is difficult suitably to reduce the illumination mark.
The led light source design; Because tunnel exit will be built interchange and riverine highway joins; And consider most of drivers the tunnel portal speed of a motor vehicle can reduce and operation security (the 60km/h hazard index is 1 o'clock; 80km/h then is 55) etc. factor, the operating speed in the tunnel should be limited in 80km/h, the illumination Design speed of a motor vehicle is pressed the 80km/h value.Through on-the-spot repetition measurement, brightness 120 (S) measured value: 3161cd/m2 outside the hole, tunnel.Design speed 80km/h; Lighting criteria is got 0.88 times of " standard " setting; Luminous efficiency＞the 751m/W of LED pipe, colour rendering index＞75, beam angle scope: 53 °～123 °; Basic segment brightness designs by 2.5cd/m2, does not consider light fixture maintenance factor (this design has considered that decay is not more than 30%).Thus, two row 115W LED tunnel illuminating lamp double side wall symmetric arrangement are adopted in tunnel base lighting and emergency lighting; Strengthen illumination stage and be aided with two row 160W, 200W, 140W LED tunnel illuminating lamp double side wall symmetric arrangement respectively.10 meters single armed steel pole street lamps are adopted in the illumination of leading the way, and join 168W LED lamp and import and export the bilateral symmetry layout in the tunnel.LED scheme light fixture layout drawing is as shown in Figure 2.Wherein, 21 are the base lighting light fixture, and 22 for strengthening lighting.θ
3Be base lighting instrument corresponding beam angle, θ
4For strengthening the corresponding beam angle of illuminations.In this embodiment, θ
3Be 78 °, θ
4It is 79 °.Said beam angle is: on one of normal beam center line plane, luminosity equals the angle between two directions of 50% maximum luminosity.Wherein, said leading the way to connecting the highway section of vcehicular tunnel two ends and road.The tunnel illumination system is provided with as shown in table 5.
Table 5 illuminator is provided with table
