Description

Daylight guide apparatus for tunnel}

The present invention relates to a daylight inflow device for tunnels, and more particularly, it is possible to effectively reveal the boundary of the tunnel entrance corresponding to the long and wide section area of several tens of meters or more by using the mined daylight. It relates to a daylight inlet device for a tunnel.

In general, the dissemination, saving and preservation of energy, which is increasing in proportion to economic development, is very important as part of the national policy. Significance is of great importance.

On the other hand, a small amount of energy consumed throughout the year in the domestic energy consumption is used for the lighting device to illuminate the room, the daylight inflow device to replace the indoor lighting device by using daylight in the daytime in accordance with the trend of energy saving Has been developed.

Such a conventional daylight inflow device has a form of a light duct installed in the windows of the building and the ceiling of the room to light daylight by irradiating the room, the specific configuration of which is shown in FIG.

Conventional daylight inlet device is a duct-shaped body 10 that extends from the outside of the building to the interior ceiling through the window (W), the light inlet 20 is formed in the outer portion of the building of the body 10, the inflow of daylight, It is installed in the body 10 to correspond to the light inlet 20 and formed on the lower surface of the reflector 30 reflecting the main light to the indoor side and the interior end of the body 10 to reflect the reflected light by the reflector 30. It consists of a light discharge port 40 to pass through and irradiate the room.

Such a conventional daylight inflow device is developed to be used in a building in which most people live, and the distance between the light inlet 10 and the light outlet 40 is only a few meters to illuminate the interior of a limited narrow space. Through the 20 to receive as much daylight as possible and to minimize the light loss, and delivers the daylight through the reflector 30, etc. It is sufficient to ensure that the transmitted daylight is discharged through one light outlet 40 is made of a relatively simple configuration .

On the other hand, the tunnel through which the car passes is equipped with a large amount of lighting device to illuminate the interior, especially when the driver's eyes adapted to the bright illumination by daylight enter the dark tunnel and temporarily adapt to the darkness. In order to prevent the loss of vision (black hole phenomenon), the tunnel entrance has a very bright illumination corresponding to the external daylight illumination (illumination at the boundary of the tunnel entrance) and a bright illumination gradually relaxed as it proceeds inside the tunnel. It is essential to secure the lighting degree of the transition part and the relaxation part of the tunnel entrance.

In particular, the boundary portion is provided to have the illumination degree higher than the basic illumination degree inside the tunnel as well as the illumination degree of the transition part or the relaxation part in order to equip the illumination degree to correspond to the bright illumination degree of the main light. Since the lighting devices are installed and operated during the day, the energy consumption is high.

In such tunnels, it is necessary to save energy by using a daylight inflow device for mining and illuminating outside daylight. However, the boundary part corresponds to a long and wide section of more than a few tens of meters, and thus should be revealed. There is a problem that it is impossible to apply the conventional daylight inflow apparatus described above.

That is, the tunnel daylight inlet device for the tunnel should effectively transmit the daylight by a distance of several tens of meters, and the boundary portion of the tunnel entrance corresponding to the long and wide section region should be properly identified, so that one reflector 30 and the light outlet 40 are provided. Conventional daylight inlet device for discharging the daylight is provided to one light outlet 40 has a limitation that can not be applied to the tunnel.

In particular, the number of tunnels installed in Korea is increasing rapidly in order to meet the recent increase in traffic volume and to shorten the travel distance between regions in order to save energy and time required by vehicles, and to brighten the daylight Considering the required illuminance of the boundary portion, which requires much brighter illumination than the basic illumination of the tunnel to correspond to the illumination, the development of the daylight inflow device for tunnels for energy saving is urgently needed.

In order to solve the above problems, the present invention effectively transmits the daylight flowing into the hollow part in the tunnel inward direction so that the daylight is effectively irradiated on the road inside the tunnel as well as the road inside the tunnel at the boundary of the tunnel entrance. By doing so, it is an object of the present invention to provide a tunnel light daylight inflow device that can be preferably applied to the entire boundary of the tunnel inlet.

In order to solve the problems as described above, the chief daylight inlet device for a tunnel according to the present invention has a long duct shape to be installed along the longitudinal direction of the tunnel in the boundary ceiling of the tunnel inlet, the hollow body therein; A light inlet formed at an end of the tunnel inlet side of the body so that daylight flows into the hollow part; A plurality of light outlets formed on a lower surface of the body so that the chief light flowing into the hollow portion is irradiated onto an inner road of the tunnel located below the body; And a plurality of reflectors disposed between the plurality of light outlets, respectively, for reflecting the main light inside the hollow part, wherein the plurality of light outlets are lowered to the light inlet side with respect to the bottom surface of the hollow part. Each of the plurality of reflection parts is formed to have an inclination angle α, and each of the plurality of reflection parts is formed to have an inclination angle β so that the opposite side of the light inlet is lowered.

Angles α in which the plurality of light outlets are inclined with respect to the bottom surface of the hollow part may be provided at 3 ° to 7 °, respectively.

Angles β inclined with respect to the bottom surface of the hollow part of the plurality of reflectors may be provided at 3 ° to 7 °, respectively.

The angle of inclination of the plurality of light outlets with respect to the bottom surface of the hollow part may be formed to decrease toward the opposite side of the light inlet.

An angle β inclined with respect to the bottom surface of the hollow part of the plurality of reflecting parts may be formed to increase toward the opposite side of the light inlet.

The angle α in which the plurality of light outlets are inclined with respect to the bottom surface of the hollow part may be formed to decrease linearly or step by step toward the opposite side of the light inlet.

An angle β in which the plurality of reflection parts are inclined with respect to the bottom surface of the hollow part may be formed to increase linearly or step by step toward the opposite side of the light inlet.

The plurality of reflection parts may include a reflection member installed to reflect the main light on an upper surface of the inside of the hollow part.

The ceiling surface of the hollow part may be provided to be inclined so that its height becomes lower toward the opposite side of the light inlet from the light inlet along the longitudinal direction of the body with respect to the bottom surface of the hollow part provided in parallel with the inner road. have.

According to the tunnel daylight inlet device of the present invention, the light outlet and the reflecting portion are alternately arranged in the longitudinal direction on the lower surface of the body, and the light outlet and the reflecting portion are inclined so as to lower the light inlet side and the opposite side of the light inlet, respectively. As a result, since the chief light flowing into the hollow portion and reflected from the reflecting portion can proceed deeper toward the inner side of the tunnel, the chief light can be effectively irradiated not only on the inner road at the tunnel entrance side but also on the inner road inside the tunnel at the boundary portion of the tunnel entrance. have.

In particular, the inclined angle of the light outlet is smaller than the inside of the tunnel inlet side, and the longitudinal width thereof is larger than the inside of the tunnel inlet side, so that the main light flowing into the hollow portion is formed at the inside of the tunnel more than the tunnel inlet side. By enhancing the opportunity to be irradiated into the inner road can be further enhanced the effect of expanding the light irradiation on the inner road inside the tunnel.

In addition, since a separate reflecting member having a high reflectance is provided on the upper surface of the plurality of reflecting portions, that is, the lower side of the hollow portion, the primary light may be reflected and transmitted to the inside of the tunnel with little loss, that is, high efficiency.

In addition, since the ceiling surface of the hollow portion is inclined with respect to the bottom surface of the hollow portion provided in parallel with the inner road, compared to the case where the ceiling surface and the bottom surface are parallel, the main light flowing into the light inlet is reflected inside the hollow portion. As the number of times increases, it can be delivered further in the tunnel inward direction.

As a result, the light irradiation imbalance of the daylight inflow device at the tunnel entrance side and the inside of the tunnel is alleviated at the boundary of the tunnel inlet part, and thus can be preferably applied to the boundary part. The use of the lighting device and the operation of the boundary energy required by the operation can be greatly reduced.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In the tunnel daylight inflow apparatus according to the present invention, the tunnel entrance portion consisting of the boundary portion, the transition portion and the relaxation portion in order from the entrance of the tunnel to the inside of the tunnel, among them, especially the boundary portion is provided to mine daylight and irradiate the internal roads of the boundary portion. It is a device for.

Hereinafter, with reference to the accompanying Figures 2 to 7b, the configuration and operation effects of the daylight inflow apparatus 100 for a tunnel according to a preferred embodiment of the present invention will be described in detail.

Tunnel daylight inflow apparatus 100 according to a preferred embodiment of the present invention, including a body 110, the light inlet 120, the light outlet 130 and the reflector 140.

The body 110 is installed along the longitudinal direction of the tunnel on the boundary (TE) ceiling of the tunnel inlet, and has a long duct shape having a hollow portion 111 formed therein, and serves to transmit daylight. It forms the main skeleton of the device 100.

The inner surface of the body 110 is made of a material having a high reflectance because the main light introduced into the light inlet 120 must be reflected while being transmitted from the inside of the body 110.

3 and 4, the bottom surface 111b of the hollow portion 111 is provided in parallel with the internal road IR of the tunnel, and the ceiling surface 111a of the hollow portion 111. Is inclined by about 0.5 ° with respect to the bottom surface 111b so that the inner side is lower than the tunnel entrance TE 'side.
That is, the height of the ceiling surface 111a of the hollow part 111 toward the opposite side of the light inlet 120 along the longitudinal direction of the body 110 from the light inlet 120 with respect to the bottom surface 111b. It is provided to be inclined to be lowered.

As a result, the main light flowing into the hollow part 111 through the light inlet 120 may further cause a reflection phenomenon in the hollow part 111 than when the ceiling surface 111a is parallel to the bottom surface 111b. It is effectively transmitted along the hollow part 111 toward the tunnel. This will be described in more detail in the following description of the operation and use of the present invention.

In a preferred embodiment of the present invention, the body 110 is provided similarly to the rectangular parallelepiped shape, but is provided if it is provided in the form of a duct that can transmit daylight, the shape is not limited thereto.

The light inlet 120 is formed in an upward direction at an end portion of the tunnel inlet TE 'of the body 110 to receive daylight as the hollow part 111. That is, the end of the body 110 in which the light inlet 120 is formed is located outside the tunnel to be exposed to daylight.

As shown in FIG. 3, at the end of the body 110 in which the light inlet 120 is formed, the bottom part 111d of the hollow part 111 is provided in parallel with the internal road IR of the tunnel. It is formed to be bent at an angle of about 166 ° with respect to the bottom surface 111b of the hollow portion 111, the ceiling portion 111c of the hollow portion 111 is bent at an angle of about 169 ° with respect to the ceiling surface 111a. Is formed.

The inner surface of the ceiling portion 111c and the bottom portion 111d of the hollow portion 111 is made of a material having high reflectivity, and reflects the primary light flowing into the light inlet 120 into the hollow portion 111. When the sun's altitude is low, the chief light entering through the light inlet 120 is reflected by the bottom portion 111d of the hollow portion 111 and introduced into the hollow portion 111, and when the sun's altitude is high, the mineral oil Daylight entering through the inlet 120 is reflected in the bottom portion 111d and the ceiling portion 111c of the hollow portion 111 in order and flows into the hollow portion 111.

That is, the ceiling part 111c of the hollow part 111 blocks most of the daylight passing through the light inlet 120 by blocking the main light reflected by the bottom part 111d from being reflected upward when the sun's altitude is high. This hollow portion 111 is allowed to flow.

In a preferred embodiment of the present invention, the angle formed by the ceiling portion 111c and the bottom portion 111d of the hollow portion 111 with respect to the ceiling surface 111a and the bottom surface 111b of the hollow portion 111 respectively. In Seoul, South Korea was provided with 166 ° and 169 ° based on the maximum solar altitude of the winter solstice, it can be changed according to the maximum solar altitude of the region where the daylight inlet device 100 for tunnels of the present invention is installed, As the shape of the body 110 and the light inlet 120 may be changed, the present invention is not limited thereto.

As shown in FIGS. 3 and 4, the light outlet 130 is located closest to the tunnel inlet TE 'at the boundary portion TE and is disposed on the lower surface of the body 110 except for the frontal head to which the main light is directly irradiated. Is formed in a rectangular shape, a plurality is formed along the longitudinal direction of the body 110 at a predetermined interval is a place where the primary light flowing into the hollow portion 111 through the light inlet 120 is passed through.

Each of the plurality of light outlets 130 may be provided with a diffusion member 131 for evenly spreading daylight.

The reflector 140 serves as a part of the body 110 positioned between the plurality of light outlets 130 to reflect the main light inside the hollow part 111. That is, the chief light introduced into the hollow part 111 through the light inlet 120 is repeatedly reflected in the hollow part 111 and proceeds toward the inner side of the tunnel, while part of the light is discharged through the light outlet 130 and the rest. Some of the light reflected from the reflector 140 proceeds further toward the inner side of the tunnel.

A plurality of reflecting members 141 having a very high reflectance reflecting main light may be provided on the upper surface inside the hollow part 111 of the plurality of reflecting parts 140. The plurality of reflecting members 141 increases the transmission efficiency by reducing losses in transmitting the chief light in the tunnel in the hollow part 111.

In a preferred embodiment of the present invention, the reflector 140 is implemented to be formed as a portion of the body 110 positioned between the plurality of light outlets 130 formed therebetween, but is not limited thereto. After forming a long long hole to form the body (110) on the lower surface of the body (110), a plurality of reflecting units 140 are provided separately at predetermined intervals in the long hole to be implemented in such a way that a plurality of light outlets 130 are formed. It may be.

On the other hand, as described above, the light outlet 130 and the reflector 140 has a form that is alternately provided on the lower surface along the longitudinal direction of the body 110, as shown in Figures 2 to 4 As described above, the plurality of light outlets 130 are formed to be inclined so as to lower the light inlet port 120 side with respect to the bottom surface 111b of the hollow part 111 provided in parallel with the tunnel internal road IR. The reflector 140 is formed to be inclined so that the opposite side of the light inlet 120 is lowered, respectively.

When the light outlet 130 and the reflector 140 are formed to be inclined in this way, the main light incident on the reflective member 141 of the reflector 140 after being reflected on the ceiling surface 111a of the hollow part 111 is reflected. In the hollow part 111, the light is reflected in a direction that can be incident deeper into the tunnel inward direction. Accordingly, the amount of light emitted through the light outlet 130 inside the boundary TE is improved while the daylight is effectively transmitted to the inside of the boundary TE through the hollow 111.

On the other hand, the amount of light emitted through the light outlet 130 at the tunnel inlet TE 'of the light outlet TE decreases while the amount of light at the tunnel inlet TE' of the light outlet TE is excessive and is inside the tunnel. The amount of light can be alleviated to some extent due to insufficient imbalance.

Here, the angle α in which the light outlet 130 is inclined with respect to the bottom surface 111b of the hollow part 111, and the angle in which the reflecting part 140 is inclined with respect to the bottom surface 111b of the hollow part 111. As for ((beta)), 3 degrees-7 degrees are preferable.

The reason is that when the angles α and β of the light outlet 130 and the reflector 140 are inclined with respect to the bottom surface 111b of the hollow part 111, the effect is insignificant. When the angle α is inclined with respect to the bottom surface 111b of the hollow part 111 is greater than 7 °, the daylight emission through the light outlet 130 is reduced, and the reflector 140 is hollow. When the angle β inclined with respect to the bottom surface 111b of the portion 111 is greater than 7 °, the main light reflected from the ceiling surface 111a of the hollow portion 111 may enter the reflecting portion 140. This is because the range of the angle is largely limited and thus the reflection transmission of the chief light by the reflector 140 is inhibited, so that the amount of light transmitted to the inside of the tunnel in the hollow part 111 may be reduced.

In a preferred embodiment of the present invention, the light outlet 130 and the reflector 140 is the same as the longitudinal width and the inclination angle of the body 110 is implemented, but is not limited thereto. 5A through 5C are cross-sectional views illustrating various modified embodiments of the light outlet 130 and the reflector 140 with respect to the longitudinal width and the inclination angle of the body 110.

That is, as shown in FIG. 5A, the light outlet 130 has a smaller width in the longitudinal direction of the body 110 than the reflector 140, and the light outlet 130 has a bottom surface 111b of the hollow part 111. The angle α inclined with respect to the reflector 140 may be greater than the angle β inclined with respect to the bottom surface 111b of the hollow part 111.

In addition, as shown in FIG. 5B, the angles α1, α2, and α3 inclined by the light outlet 130 with respect to the bottom surface 111b of the hollow part 111 may be provided in a predetermined section as the tunnel inlet TE ′ moves inward. Step by step (ie, α1> α2> α3), and the angle β at which the reflector 140 is inclined with respect to the bottom surface 111b of the hollow part 111 is inward from the tunnel entrance TE 'side. As it proceeds to step may be implemented to be larger step by step (that is, β1 <β2 <β3).

In addition, as illustrated in FIG. 5C, the angles α1, α2, and α3 inclined with respect to the bottom surface 111b of the hollow part 111 and the reflector 140 are the bottom of the hollow part 111. The angles β1, β2, and β3 inclined with respect to the surface 111b may be implemented to gradually decrease or increase in linear proportion to the traveling distance as the inwardly progressing from the tunnel entrance TE ′ side.

The most preferred here may be the case shown in Figure 5c, the reason is that when the longitudinal width and the inclined angle of the light outlet 130 and the reflector 140 is provided in this way, the inclination of the reflector 140 As the load increases, the amount of light delivered to the inside of the tunnel increases and the longitudinal width of the light outlet 130 increases toward the inside of the tunnel, so that a relatively large amount of light passes through the light outlet 130 inside the tunnel under the same conditions. Because it can.

In other words, the amount of light present in the hollow portion 111 decreases toward the inside of the tunnel in the hollow portion 111. Therefore, in order to increase the amount of light irradiated inside the tunnel of the boundary portion TE, the amount of light emitted from the hollow portion 111 increases. This is because it is effective to implement the light outlet 130 so that a large amount of light can be emitted.

If the above-mentioned primary daylight inflow device for the tunnel is insufficient to satisfy the amount of light required for the interior road located at the inner side of the tunnel inlet of the tunnel, particularly the tunnel entrance TE ', the only separate lighting device is sufficient. It is sufficient to install and operate inside the tunnel, so that it is possible to solve the illumination of the entire boundary TE of the tunnel entrance at low cost.

4 and 6a to 7b, the operation and use state of the daylight inflow apparatus 100 for a tunnel according to a preferred embodiment of the present invention will be described in detail.

As shown in FIG. 4, the tunnel daylight inflow apparatus 100 according to the present invention is installed along the longitudinal direction of the tunnel at the center of the boundary (TE) ceiling of the tunnel inlet, and at this time, the end of the light inlet 120 is formed. Protrudes to the outside of the tunnel is installed so that daylight flows into the light inlet (120).

The irradiation angle of the daylight naturally irradiated to the light inlet 120 of the tunnel daylight inlet device 100 installed in this way is continuously changed according to time and season, Figures 6a and 7a is irradiated at noon of the lower and winter, respectively It is sectional drawing which shows the optical path which main light advances with respect to the irradiation angle of the main light which becomes.

6A, when the irradiation angle of the chief light is large, the chief light incident on the light inlet 120 is sequentially reflected to the bottom 111d and the ceiling 111c of the hollow 111, and then the hollow 111. Are repeatedly reflected on the bottom surface 111b and the ceiling surface 111a.

Thereafter, a part of the main light introduced into the light outlet 130 passes through the diffusion member 131 of the light outlet 130 and is discharged downward, and the other part is the reflective member 141 of the reflector 140. By reflecting by the light is transmitted to the inner depth of the hollow portion 111 with a gentle slope than that reflected by the bottom surface 111b of the hollow portion.

Here, the area where the bottom surface 111b of the hollow part 111 exists is a section corresponding to the tunnel entrance TE 'side even at the boundary portion TE, and since the main light flows directly through the tunnel entrance TE', This section does not need to be investigated.

As described above, the main light introduced into the hollow part 111 by the reflector 140 and the reflecting member 141 may be transmitted to the inside of the hollow part 111 with a short optical path and a small loss. Such daylight is repeatedly reflected from the reflecting member 141 and the ceiling surface 111a of the hollow part 111 provided in the plurality of reflecting parts 140, and the relaxation part TE-3 through the plurality of light outlets 130. Is investigated.

Accordingly, the amount of light emitted through the light outlet 130 positioned at the tunnel entrance TE ′ of the boundary TE is relatively smaller than that of the light outlet 130 and the reflector 140, and the boundary portion ( The amount of light emitted through the light outlet 130 located inside the tunnel of the TE is increased, so that the amount of light irradiated to the inner road IR of the insufficient tunnel inner boundary TE may be increased.

On the other hand, when the chief light flowing into the hollow portion 111 is reflected from the ceiling surface 111a, the ceiling surface 111a is provided to be inclined by about 0.5 °, thereby further reflecting the chief light inside the hollow portion 111. Induces this daylight is transmitted farther into the hollow portion 111.

FIG. 6B illustrates a case where the ceiling surface 111a 'of the hollow portion 111 is horizontally provided with the bottom surface 111b in order to compare with the case of the preferred embodiment of the present invention shown in FIG. 6A. 6A and 6B, the main light that draws the light path of FIG. 6A is further bent by the inclined ceiling surface 111a to induce additional reflection by the first reflector 140. It can be seen that the daylight is further transmitted into the hollow part 111.

On the other hand, as shown in FIG. 7A, when the irradiation angle of the chief light is small, the chief light incident on the light inlet 120 is reflected on the bottom 111d of the hollow part 111 and immediately after the ceiling surface of the hollow part 111 ( It is reflected by 111a and then repeatedly reflected by the bottom surface 111b and the ceiling surface 111a of the hollow part 111.

Thereafter, a part of the chief light is discharged downward through the diffusion member 131 of the light outlet 130 located at the tunnel inlet TE 'side of the boundary TE, and the other part is reflected by the reflector 140. After being reflected by the member 141 and proceeding deeper into the hollow part 111, it is discharged through the light outlet 130 positioned inside the tunnel, similar to the description of FIG. 6A.

In addition, at this time, the amount of light emitted through the light outlet 130 located at the tunnel inlet TE ′ of the boundary portion TE by the light outlet 130 and the reflector 140 inclined is a light outlet. The amount of light emitted through the light outlet 130 located inside the tunnel is increased and the amount of light irradiated to the inner road IR inside the insufficient tunnel is increased than when the 130 and the reflector 140 are horizontal. This is also similar to the description of FIG. 6A.

FIG. 7B illustrates a case where the ceiling surface 111a 'of the hollow part 111 is horizontally provided with the bottom surface 111b in order to compare with the case of the preferred embodiment of the present invention shown in FIG. 7A. 7A and 7B, the main light that draws the light path of FIG. 7A is further bent by the inclined ceiling surface 111a to cause additional reflection by the first reflector 140. It can also be seen that the daylight is further transmitted into the hollow 111.

As described above, according to the tunnel daylight inflow apparatus 100 according to the present invention, the light outlet 130 and the reflector 140 are alternately arranged along the longitudinal direction on the lower surface of the body 110, the light outlet 130 and the reflector 140 are inclined so as to lower the light inlet 120 side and the opposite side of the light inlet 120, respectively, so that only the tunnel inlet TE 'side at the boundary TE of the tunnel inlet. In addition, since the chief light is effectively irradiated to the inner road IR inside the tunnel, it may be preferably applied to the entire boundary TE.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and variations belong to the appended claims. will be.
