The present invention relates to an optical duct device, and more particularly, to an optical duct device that can selectively transmit external sunlight to a specific location in the room, and a method for controlling the transmission of sunlight using the same.

Recently, as the level of culture improves, the demand for quality improvement of architectural space is increasing. As one of them, a technology for introducing natural light into a room has been developed. When natural light is introduced into a room, energy can be saved, and a bright and comfortable indoor environment can be provided. This not only improves the living efficiency of residents, but also has a positive psychological and physiological effect on the residents.

As described above, one of the methods for introducing natural light into the indoor space uses a light duct. Like the ducts that were previously used for ventilation, light ducts are used to deliver external sunlight to the room using a duct structure. Outside sunlight is transmitted from the outside to the room along the light duct can increase the illuminance of the room.

However, the conventional light duct has a disadvantage that the user can not arbitrarily choose whether to inflow of sunlight because it always introduces natural light outside regardless of whether there is a room in the room. In addition, since the transmission rate of natural light decreases as it moves away from the entrance of the light duct into which the external natural light flows, there is a problem that the light duct is not effective in the interior space.

The present invention relates to an optical duct device 10 and a method for controlling indoor illuminance using the same. The present invention is used to increase the illuminance of the room by transmitting the natural light, such as the sunlight of the outdoor (O) to the room, to effectively transmit the natural light to the interior space of the room, and to selectively supply natural light to a specific space of the room do. To this end, each component constituting the present invention will be described in detail.

1 illustrates the interior of a building to which an embodiment of the present invention is applied. For convenience of description, the interior space of the building will be described first, and the interior space can be divided into a plurality of spaces. In FIG. 1, the interior is arbitrarily divided into three spaces, the first space R1, the second space R2, and the third space from the outermost space O and the outermost space where natural light is supplied to the outermost space, respectively. Separated by space (R3). Here, the space may be blocked by a separate wall, such as between the first space R1 and the second space R2, and a separate partition wall may be formed between the second space R2 and the third space R3. Spaces may be distinguished by location without.

Looking at the structure of the natural light device, the duct body 11 is installed across the interior space to form the skeleton. Duct body 11 can be seen as a kind of tube (tube) structure with a continuous empty space therein. The duct body 11 may be installed directly on the ceiling of the indoor space as shown in FIG. 1, or may be installed in an empty space between a concrete slab and a plaster board constituting the ceiling. The duct body 11 may extend in one direction or may branch in several directions. The interior of the duct body 11 has a transmission space (S) which is an empty space, the transmission space (S) is coated with a material having a high reflectance to reflect natural light, or the duct body 11 itself has a high reflectance It can be made of material.

On one side of the duct body 11 there is a light inlet 20 which is an inlet through which natural light flows, and on the other side there are light outlets 31, 32 and 33 to which natural light is supplied. The light inlet 20 may be opened to the outside of the building so that natural light from the outside may be introduced, and the light emitters 31, 32, and 33 are open toward the interior space. An empty space inside the duct body 11 is connected to each other by the transmission space S between the light inflow portion 20 and the light emission portions 31, 32, and 33.

In the present embodiment, the light inlet 20 is one, but the light emitter 31, 32, 33 is composed of a plurality. More precisely, the light emitting units 31, 32, and 33 are each located at positions corresponding to the first to third spaces R1 to R3 that partition the indoor space described above. For better understanding, each of the light emitting units 31, 32, and 33 will be divided into a first light emitting unit 31 and a third light emitting unit 33.

As such, since the light emitting parts 31, 32, and 33 are present in one light duct device 10, the natural light introduced through the light inlet part 20 is each of the light emitting parts 31, 32, and 33. It can be supplied through). However, if natural light is supplied through all the light emitting parts 31, 32, and 33, the inner space farthest from the light inlet, that is, the third space R3, has only a relatively small amount of natural light compared to the first space R1. It must be supplied. In order to improve this point, in the present invention, a plurality of opening and closing means 12 are installed in the duct body 11 to supply natural light only to a desired place, thereby preventing natural light from being wasted in the middle.

The duct body 11 has opening and closing means 12. The opening and closing means 12 is installed in the duct body 11 adjacent to the light emitting parts 31, 32, and 33 to control the supply of natural light through the light emitting parts 31, 32, and 33. Do it. That is, when the opening and closing means 12 is opened, natural light is supplied through the light emitting parts 31, 32, and 33, and when it is closed, natural light passes through the light emitting parts 31, 32, and 33 without being supplied. Therefore, the opening and closing means 12 is preferably installed in the first light emitting portion 31 to the third light emitting portion 33, respectively.

The structure of the opening and closing means 12 is shown well in FIG. As shown in this, the opening and closing means 12 is installed in a rotatable form on the duct body (11). The opening and closing means 12 opens and closes the light emitting parts 31, 32, and 33 through rotation. That is, the opening and closing means 12 selectively blocks the transmission space S through rotation to induce natural light to the light emitting parts 31, 32, and 33. For reference, Figure 2 is expressed in the open state about half of the opening and closing means (12).

The opening and closing means 12 is installed at the edges of the light emitting parts 31, 32, and 33, and intercepts the transmission space S through rotation, so that natural light is reflected by the opening and closing means 12 so that the light emitting part ( 31, 32, 33) is supplied to the room. To this end, the opening and closing means 12 is preferably made of a material with high light reflectance.

The opening and closing means 12 largely includes a rotary part 13 and a power unit 16. The rotating part 13 is a part rotatably installed in the delivery space (S) of the duct body 11, the power unit 16 is provided in the duct body 11 through the wire 17 It is connected to the rotating part 13 serves to rotate the rotating part (13). In this embodiment, the power unit 16 is composed of an electric motor, is installed on the outer surface of the duct body 11 does not interfere with the transmission of natural light.

Looking at the configuration of the rotating part 13, the rotating part 13 is a portion that substantially blocks the transmission space (S). The rotating part 13 may have various shapes. In the present embodiment, the rotating part 13 is a plate structure having an outer surface of the rotating part 13. Preferably, the rotating part 13 is a reflection surface facing the transmission space S so that the natural light can be reflected in the direction of the light emission parts 31, 32, and 33 in a state where the transmission space S is blocked. 13 'is formed into an inclined surface or a curved surface. The inclination of the outer surface of the rotating unit 13 may be variously modified, for example, may have a form inclined at about 45 degrees.

The rotating part 13 rotates about the rotating shaft 15, and the power for rotation is transmitted by the power part 16 connected through the wire 17. That is, when the power unit 16 winds the wire 17, the rotating unit 13 rotates clockwise with respect to the lifted direction, that is, FIG. 2, intercepts the transmission space S, and transmits natural light to the first light emission unit 31. In the direction of. When the power unit 16 rotates in the opposite direction, the wire 17 is released and the rotating unit 13 rotates counterclockwise. Alternatively, the power unit 16 may directly rotate the rotating unit 13 without the wire 17 as a medium, but in this embodiment, to reduce the volume occupied in the duct body 11, the duct body ( 11) It has a form that can be installed on the outside.

The rotating shaft 15 of the rotating part 13 is at the edge of the light emitting parts 31, 32, 33, and the weight part 14 is provided at the end of the rotating part 13 corresponding to the opposite side of the rotating axis 15. It is provided so that the rotating part 13 is rotated in the direction blocking the light emitting parts (31, 32, 33). That is, when the wire 17 pulling the rotary part 13 is relaxed, the rotary part 13 rotates in a direction (counterclockwise direction with reference to FIG. 2) that naturally prevents the light emission parts 31, 32, and 33 by gravity. It is.

In this process, the power unit 16 may adjust the rotation to adjust the angle of the rotation unit 13. When the angle of the rotating part 13 is adjusted, since the reflection of the natural light by the rotating part 13 also changes, the amount of natural light emitted through the light emitting parts 31, 32, and 33 may also vary. Through this, the amount of light delivered to the room may be finely adjusted.

Referring to FIG. 3, FIG. 3 (a) shows the rotating part 13 completely blocking the first light emitting part 31. In FIG. 3 (b), the rotating part 13 rotates about 45 degrees. Is shown. Finally, Figure 3 (c) is shown that the rotating part 13 is completely lifted by the power unit 16 to block the transmission space (S). In the state of FIG. 3C, the rotating part 13 reflects natural light toward the first light emitting part 31 to increase the illuminance of the first space R1. Of course, even in the state of FIG. 3B, the rotating part 13 may reflect natural light toward the first light emitting part 31 to some extent.

As shown in FIG. 7, a branching means 50 may be further provided in the delivery space S of the duct body 11. For reference, Figure 7 is a cross-sectional view of the internal structure of the duct body 11 from above. The branching means 50 is rotated about the rotating shaft 51 orthogonal to the rotating shaft 15 of the opening and closing means 12 in the delivery space (S) of the duct body (11). The branching means 50 serves to control the direction of movement of the natural light transmitted through the delivery space (S) through rotation. That is, when the duct body 11 splits into two branches, the branching means 50 may adjust which of two branches transmits natural light.

There is a branch plate 55 that rotates about the rotation axis 51 of the branching means 50, the branch plate 55 reflects the natural light transmitted. For example, referring to FIG. 7 (a), the natural light that has been directed to the right in the delivery space S is reflected upward to transmit natural light to the first branch duct 10A. And when the branch plate 55 is rotated around the rotation axis 51 as shown in Fig. 7 (b) to reflect the natural light that went straight to the right in the delivery space (S) to the lower side to transmit the natural light to the third branch duct (10C). Done. Meanwhile, in FIG. 7C, the branch plates 55 extend in the direction parallel to the delivery space S with the rotational shafts 15 and 51 focused on the second branch duct 10B without being reflected by natural light. It is shown to convey to.

Next, a method of controlling indoor illuminance using the optical duct device of the present invention will be described.

8 is a flowchart illustrating a process of adjusting the indoor illuminance using the optical duct device 10 according to the present invention. As shown in the drawing, the process of adjusting the interior illuminance using the optical duct device 10 of the present invention determines whether the occupant is present in the indoor space divided into the first space R1 to the third space R3. Can begin with. This is because the space without occupants does not need to adjust the illuminance of the room, and the illuminance of the space where the occupants are required to be increased.

To this end, a sensor (not shown) may be installed in the indoor space. The indoor space is provided with a detection sensor for detecting the presence or absence of the occupant, and an illumination sensor for measuring the illumination of the indoor space. A sensing sensor and an illuminance sensor may be installed in the first space R1 to the third space R3 to check the state of each space.

When the control of the indoor illuminance is started (S10), a step (S20) of determining whether or not the first occupant of the first space R1 is occupied in the partitioned indoor space is preceded. If there is no occupant in the first space R1, a step S30 of determining whether there is a occupant in the second space R2 is continued, and if there is no occupant in the second space R2, there is a material owner in the third space R3. Determining step S40 is followed. Of course, such a process of determining whether there are occupants may be performed at the same time. The presence of occupants is determined by the sensor.

Looking in more detail the process of determining the presence of the occupants, since the first space (R1) is the innermost space is difficult to transmit the external natural light can be scheduled to have a priority in the transmission of the natural light. Then, the control is sequentially performed while moving toward the outside, that is, the direction in which the natural light flows.

First, the first light emitting part 31 connected to the first space R1 is in an open state. That is, the opening and closing means 12 adjacent to the first light emitting part 31 is opened to reflect the natural light toward the first light emitting part 31. If the occupant is present in the first space R1, natural light may be supplied to the first space R1 by maintaining the state. This state is illustrated in FIG. 4.

If there are no occupants in the first space R1 and there are occupants in the second space R2, the illuminance of the second space R2 is measured to determine it (S35). If the illuminance of the second space R2 is greater than or equal to the reference value, the natural duct need not be supplied. Therefore, the light duct control may be terminated. The reference value here is 400 lx. If the illuminance of the second space (R2) is lower than the reference value, it can be determined that the room is dark, the control unit to operate the opening and closing means 12 to open the second light emitting unit 32 (S37). This state is shown in FIG.

If there are no occupants in the second space R2, it is determined whether there are occupants in the third space R3 (S40). If there is no occupant in the third space (R3), it is not necessary to increase the illuminance, so the control is terminated. If there is a occupant, the controller determines the illuminance of the third space (R3) by measuring the illuminance (S45). If the illuminance of the third space R3 is greater than or equal to the reference value, it is unnecessary to supply more natural light, so the light duct control may be terminated. If the illuminance of the third space R3 is lower than the reference value, it may be determined that the interior is dark, and the control unit operates the opening and closing means 12 to open the third light emitting part 33 (S47). This state is shown in FIG.

In this way, the control unit operates the opening and closing means 12, the external natural light through the light emitting parts (31, 32, 33) connected to the first space (R1) to the third space (R3) where the occupant is present in the previous step To be delivered. The control unit supplies natural light to the first space R1 to the third space R3 only when the measured illuminance of the indoor space is equal to or less than a reference value, thereby making it possible to use the optical duct device 10 more efficiently.

At this time, the control unit may adjust the amount of natural light supplied to the indoor space by adjusting the opening and closing means 12 according to the degree of falling below the reference value by comparing the illuminance size and the reference value of the indoor space. That is, the control unit may open or close the opening and closing means 12 to completely open or close the light emitting portions 31, 32 and 33, and may adjust the amount of natural light supplied by only partially opening the light emitting portions 31, 32 and 33. will be.
