FIG. 1 is a view schematically showing a state in which a rotating type reflection panel device according to an embodiment of the present invention is installed in a skylight, FIG. 2 schematically shows a state in which a fixed type reflection panel device according to an embodiment of the present invention is installed in a skylight Fig.

First, it is assumed that the rotating type reflection panel device 10 shown in FIG. 1 is installed in a skylight provided in a building space.

1, the rotary type reflective panel device 10 includes a reflective panel part 100, a circular frame driving rail part 200, a rotation driving part 300, an angle adjusting driving part 400 and a cover 500 do.

The reflective panel unit 100 reflects natural light from the outside into the room. The reflective panel unit 100 is formed in a circular shape. To this end, the reflection panel unit 100 includes a plurality of reflection panels 110 and a lower circular frame 120. A plurality of reflection panels (110) are rotatably coupled to the lower circular frame (120). That is, the plurality of reflection panels 110 are coupled to be partially rotatable up and down with respect to the coupling portion of the lower circular frame 120 in order to maximize the light that flows into the room according to the incidence angle of the main light, which is natural light. In addition, the plurality of reflection panels 110 may have the same length because the reflection panel parts 100 have a circular shape. The specific structure of the reflection panel 110 will be described later.

The circular frame driving rail part 200 is formed by coupling the reflection panel part 100 to the upper part thereof and using the rails so that the reflection panel part 100 can be rotated clockwise or counterclockwise Provide a guide. Particularly, the circular frame driving rail part 200 minimizes the friction caused by the rotation between the circular frame driving rail part 200 and the lower circular frame 120 of the reflection panel part 100, (Not shown) in the lower circular frame 120 in order to minimize the torque applied to the drive motor (not shown) of the motor 300. Here, the circular frame driving rail 200 may be fixedly coupled to the cover 500 or may be directly coupled to the skylight.

The rotation driving unit 300 rotatably drives the lower circular frame 120 and includes a driving motor (not shown). At this time, the rotation driving unit 300 can rotationally drive the lower circular frame 120 through a coupling method such as a gear or a belt. Of course, it is obvious that the lower circular frame 120 can be rotationally driven using another coupling method. The rotation driving unit 300 may be fixedly coupled to the cover 500 or the skylight.

The angle adjustment driving unit 400 adjusts the angle of reflection of the natural light incident from the outside by adjusting the angle of the plurality of reflection panels 110 of the reflection panel unit 100. For this purpose, the angle adjusting driver 400 includes a driving motor (not shown) for adjusting the angle.

The angle adjustment driving unit 400 includes at least one driving wire (not shown) fixedly coupled to a part of each of the plurality of reflection panels 110 to uniformly adjust the angle of the plurality of reflection panels 110 of the reflection panel unit 100 410 are pulled or loosened through a driving motor to adjust the angle of the plurality of reflection panels 110. [ The angle adjustment driving unit 400 may be fixedly coupled to the cover 500 or the skylight.

The cover 500 is configured to surround the reflection panel unit 100 to protect the reflection panel unit 100 from an external environment, and preferably has a shape of a cube or a rectangular parallelepiped. Here, examples of the external environment include effects of snow and wind. On the other hand, the cover 500 is fixedly coupled to the skylight when the reflection panel device 10 is formed in the skylight. In addition, the cover 500 can be constructed of glass or other transparent material capable of transmitting natural light, which is natural light, to the room.

1 rotates the reflection panel unit 100 in the horizontal direction through the rotation driving unit 300 in accordance with the direction of the sun, And adjusts the angle of the reflection panel 110 through the angle adjustment driving unit 400 to adjust the angle of the natural light. This allows maximum sunlight to be reflected to the room in a certain direction during the day. For example, when the building is located on the south, only the angle of the reflection panel 110 is adjusted without rotating in the horizontal direction. However, when the building is located on the site at an arbitrary angle without forming a south direction, Thereby performing a dual operation in which all the reflection panels 110 can be rotated in the horizontal direction and the angle of the reflection panel 110 can be changed. This reflects the maximum sunlight to the room in the changing direction during the day. That is, in the morning, the reflection panel unit 100 is rotated toward the east side and the reflection panel unit 100 is rotated toward the west side in the afternoon along the circumferential movement of the sun.

2, the fixed type reflective panel device 20 includes a reflective panel unit 600, an angle-adjustable driving unit 700, and a cover 800. As shown in FIG.

The reflective panel unit 600 is similar to the reflective panel unit 100 shown in FIG. 1 except that the reflective panel unit 600 is formed in a square or rectangular shape like the cover 800, 610 are not present separately and a part of both ends of the plurality of reflection panels 610 are directly coupled to the cover 800 so as to be rotatable. The lengths of the plurality of reflective panels 610 are all the same.

The angle adjusting driver 700 has the same configuration as the angle adjusting driver 400 shown in FIG. That is, the angle adjustment driving unit 700 includes at least one drive unit (not shown) for partially and fixedly coupling a plurality of reflection panels 610 to uniformly adjust the angle of the plurality of reflection panels 610 of the reflection panel unit 600, The wire 710 is pulled or loosened through the driving motor to adjust the angle of the plurality of reflection panels 610. The angle adjustment driving unit 700 may also be fixedly coupled to the cover 800 or the skylight.

Like the cover 500 shown in FIG. 1, the cover 800 is configured to surround the reflection panel unit 600 to protect the reflection panel unit 600 from an external environment, It has the shape of a rectangular parallelepiped. The cover 800 may also be constructed of glass or other transparent material that is fixedly coupled to the skylight when the reflective panel device 20 is formed in the skylight and allows natural light to pass through the room. 1 is that a plurality of reflection panels 610 of the reflection panel unit 600 are coupled to be rotatable to the cover 800 directly.

2, unlike the rotating type reflective panel device 10 shown in FIG. 1, the fixed type reflective panel device 20 shown in FIG. 2 includes an angle adjusting driving unit 700 for adjusting the natural light drawing angle according to the altitude change of the sun, The angle of the reflection panel 610 can be adjusted only through the angle of the reflection panel 610. However, the present invention is not limited thereto.

Meanwhile, the reflection panel devices 10 and 20 may be installed together with the skylight or may be installed on the skylight so as to protrude to the outside.

Hereinafter, the angle adjustment of the reflection panel device according to the embodiment of the present invention will be described with reference to FIG. Here, since the angle adjustment of the reflection panel devices 10 and 20 is performed in the same manner, the structure of the rotating type reflection panel device 10 shown in FIG. 1 will be described for convenience of explanation.

3 is a schematic view for schematically explaining an angle adjusting operation of the reflection panel device according to the embodiment of the present invention.

Referring to FIG. 3, a lower portion of both side ends of the reflection panel 110 is rotatably hinged to the lower circular frame 120, and an upper end thereof is also rotatably coupled to the driving wire 410.

One end of the driving wire 410 is fixedly coupled to the angle adjusting driving part 400 and the other end is fixedly coupled to one side of the lower first frame 120 through a restoring spring 420.

In the embodiment of the present invention, since the angle of the reflection panel 110 must be uniformly changed at a specific angle at a specific moment, at least one driving wire 410 is used to reduce the energy and facility cost, However, the technical scope of the present invention is not limited thereto, and various other configurations that can uniformly change the angle of the reflection panel 110 can be applied.

3, when the driving wire 410 is pulled by the driving of the angle adjusting driving part 400, the angle of the reflecting panel 110 is increased. On the contrary, when the driving wire 410 is loosened, The driving wire 410 is pulled toward the opposite side of the angle adjusting driving part 400 so that the angle of the reflecting panel 110 is reduced.

On the other hand, when the angle of the reflection panel 110 is less than 90 degrees, the restoring force due to its own weight is utilized. When the angle exceeds 90 degrees, (110) in the opposite direction. In this case, a balance weight or the like may be used instead of the restoring spring 420.

Hereinafter, the reflective panels 110 and 610 of the reflective panel devices 10 and 20 according to the embodiment of the present invention will be described with reference to FIG. Here, since the reflective panels 110 and 610 have the same configuration, only the reflective panel 110 shown in FIG. 1 will be described for convenience of explanation.
