（照明器具の設置台数、光源Ｗ数）が行なわれている。
照明装置の配置計画はトンネル縦断方向に対して一定に
なっている。2. Description of the Related Art The brightness (brightness) of road surfaces in roads and tunnels is specified in "Road Lighting Facility Installation Standards and Explanations" (hereinafter referred to as "installation standards"), etc. It is necessary to always maintain a required brightness in consideration of a decrease in illuminance due to contamination of the device. For this reason, in the design of conventional road / tunnel lighting, the layout plan of the lighting devices (the number of installed lighting fixtures and the number of light sources W) is performed in consideration of the decrease in illuminance due to aging described above.
The layout plan of the lighting equipment is constant in the longitudinal direction of the tunnel.

照度で設計されている。[0003] On the other hand, although the brightness of the road surface is specified by the luminance in the installation standard or the like, the design is designed by the illuminance using the average illuminance conversion coefficient obtained from the ratio of the average road surface luminance to the average road surface illuminance. I have.

明器具の清掃後における路面の明るさが、所要値を上回
り、過剰なエネルギー消費となる。In a conventional lighting design which considers a decrease in light output from a lighting fixture due to aging,
The road surface brightness at the initial stage of installation of the lighting device, after the replacement of the light source due to its life, and after the cleaning of the lighting equipment exceeds the required value, resulting in excessive energy consumption.
【０００５】また、路面の明るさを左右する路面の反射

度が確保されていないことがある。[0005] The reflection properties of the road surface affects the brightness of the road surface, with aging by dirt due to wear or dust of the pavement surface by the running vehicle, for example in the asphalt pavement, of the initial 30lx / cd / m 2 It is said that it will be 18 lx / cd / m 2 after 4 or 5 years and will be stable. Therefore, at the time of design, the average illuminance conversion coefficient of the magnetic field, which is almost stable over time, is used, and an appropriate road surface luminance may not be secured.
【０００６】また、照明器具の汚れの進行具合は、トン
ネル縦断方向に対して異なるため一方通行であれば出口
に近い照明器具ほど汚れやすくなり、光源の光出力レベ
ルが一定だと縦断方向において明るさの均一性が損なわ
れる。[0006] The degree of dirt on the lighting equipment is different in the longitudinal direction of the tunnel. Therefore, if the vehicle is one-way, the lighting equipment closer to the exit is more likely to become dirty. The uniformity of roughness is impaired.
【０００７】またトンネル内における所要の路面の明る
さ（輝度）は、トンネル内の煤煙透過率に左右され、煤
煙透過率が高いほど所要の路面輝度は低くなる。「道路

ているものとして定められており、夜間では交通量が減
少し煤煙透過率が高まることからタイマ制御で路面輝度
を低減する運用が行なわれている。The required road surface brightness (luminance) in the tunnel depends on the soot transmittance in the tunnel. The higher the soot transmittance, the lower the required road surface brightness. The required road surface brightness in a tunnel specified in the “Standards for setting up road lighting facilities and the same commentary” etc. is defined as a soot transmission rate of 50% is ensured. At night, traffic volume decreases and soot transmission rate Therefore, the operation of reducing the road surface luminance by timer control is performed.

以上となる場合、過剰なエネルギー消費となる。[0008] The traffic volume in the tunnel does not constantly and constantly fluctuate, and the smoke transmittance is 50 even during the daytime.
% Or more. The current operation of the lighting inside the tunnel controls the lighting level according to the time zone, so traffic volume decreases during the daytime and the smoke transmission rate is 50%.
In the case above, excessive energy consumption occurs.

汚れの経年変化による光出力の低下を想定したデータに
基づき、必要な路面の明るさが得られるように照明器具
の光出力を制御している。At the initial stage of installation of the lighting apparatus, after the replacement of the light source due to its life, and after the cleaning of the lighting equipment, the light output is higher than the required brightness. Therefore, the light output of the lighting fixture is controlled based on data assuming a decrease in the light output due to the secular change of the light source luminous flux and the lighting fixture so that the required road surface brightness can be obtained.
【００１０】しかし、トンネル内の照明器具の汚れによ

らず等しい光出力の制御を行なうため、トンネルの走行
方向において路面の明るさが不均一となる。However, the aging of the light output due to dirt on the luminaire in the tunnel differs depending on the length direction of the tunnel. In the case of a one-way tunnel, the luminaire closer to the exit has a faster progress of the dirt and the light output is lower. The drop is significant. In the related art, since the same light output is controlled regardless of the position of the lighting fixture in the length direction of the tunnel, the brightness of the road surface becomes uneven in the traveling direction of the tunnel.

器具に対応して一律に制御を行なっている。Furthermore, in the case of tunnel lighting using a lighting fixture whose light output varies depending on the ambient temperature such as a fluorescent lamp, a typical temperature in the tunnel is sensed, and the required light output of the light source is determined based on the temperature. Is set, and control is performed uniformly for all lighting fixtures.

るさが不均一となるという問題がある。The temperature in the tunnel may vary depending on the length direction of the tunnel. In a one-way tunnel, the temperature inside the tunnel tends to be higher as it is closer to the exit side. For example, a difference of about 10 degrees has been confirmed between the entrance side and the exit side. In the case where is used, there is a problem that the brightness of the road surface becomes uneven in the tunnel traveling direction.

For example, there are a luminance meter, a device that senses luminance by image processing using a CCD camera, and the like, and are permanently installed on a wall surface. The control device 2 sets the dimming level of the lighting fixture 1 so as to have a required road surface luminance by using the road surface luminance data obtained by the road surface luminance measuring device. Here, it is assumed that the road surface luminance measuring device is installed on the assumption that the luminance is measured in a measurement range A at a depression angle of 0.5 to 1.5 degrees from the center of the traveling lane on the road surface 7 of the road. The direction of the tunnel section in the measurement range A is the range of the road. However, if such observation conditions are not satisfied and the observation results are significantly different, the ratio between the measurement result of the road surface luminance under the above observation conditions and the measurement result is multiplied by the ratio to obtain the road surface under the required observation conditions. Assume that the luminance is estimated.

As a result, appropriate road surface luminance can be ensured in consideration of the output light flux of the lighting equipment (equipment dirt, reduction of the light flux of the lamp) and the aging of the road surface reflection characteristics.

The measurement range B is the width of the road surface 7 of the road in which the cross-section direction of the tunnel is used. The vehicle 4 has a transmitter 5 for transmitting measurement data, and the control device 2 has a receiver 6 for receiving a signal from the transmitter 5 for wirelessly transmitting and receiving.

Further, even if the dimming level of the lighting fixture 1 is the same, the brightness differs depending on the location of the tunnel due to the difference in dirt of the lighting fixture 1 and the aging of the road surface reflection characteristics. Therefore, the zones 8a, 8b
The dimming level is set in consideration of another difference in appliance contamination and the secular change of the reflection characteristic of the road surface 7.
