Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a light shielding switching type light shelf device,

Generally, the interior space of a building is designed to receive sunlight through an opening of a window or the like. Such a method of lighting can be classified into a mining method that directly receives sunlight through an opening, A mining method that indirectly accepts sunlight is being used.

The lighting system using a light shelf is formed by a reflection plate on the upper surface and fixed horizontally at the opening of the building, and reflects incident sunlight to the ceiling of the indoor space to indirectly minify the indoor space.

As described above, the lighting system using the light shelf can improve the mining efficiency because the degree of mining in the indoor space can be made more uniform than the mining method in which the sunlight is directly received.

Further, in order to further improve the light efficiency of the conventional light beam, a light shelf of a rotatable structure has been developed.

Korean Patent Laid-Open No. 10-2010-0093908 discloses a louver device having a plurality of rotatable louver blades provided in parallel to each other in a vertical direction, and a mirror made of a reflective material is formed on one surface of the louver blade And the lighting efficiency can be improved as the angle of the louver blade is adjusted by rotation of the louver vane.

Since the conventional louver system is provided with a structure in which the louver vanes are rotatable, it is possible to adjust the position or angle of the light beam in response to the altitude change of the sun, but it has a problem that it can not cope with the change of the sun position.

A light shelf unit (Korean Patent No. 10-1306640) for solving this problem was developed by the present applicant and is shown in FIG.

Referring to Fig. 1, a conventional light shelf apparatus 10 includes a rotating body 11 rotatable in left and right directions, and a light shelf 12 rotatable up and down and reflecting incidence sunlight, The rotating body 11 or the light shelf 12 is rotated along the guide portion 13 so as to correspond to the position and altitude of the light guide plate 13, thereby further improving the lighting efficiency.

When the light shelf 12 is horizontal, the conventional light shelf unit 10 reflects the sunlight to the indoor space of the building to increase the illuminance of the room. When the light shelf 12 is vertical, Since it is driven by the vertical louver that blocks the sunlight by reflecting the light to the outside, it is possible to block sunlight flowing into the indoor space without installing a separate louver.

However, as shown in FIG. 2, the conventional light shelf unit 10 horizontally drives one light shelf 12 to reflect sunlight into the indoor space. Since the rotation axis of the light beam is provided at a relatively low position , There is a problem that sunlight is directly reflected to a user inside the building 20, and glare may be caused.

In addition, since the angle of the light shelf 12 is not adjustable, it is difficult to immediately respond to the change of the sun altitude and it is difficult to maximize the mining efficiency and the light-shielding efficiency.

Furthermore, as shown in FIG. 3, when the conventional light shelf unit 10 is driven by a louver, incident sunlight is reflected on a pedestrian or the like outside the building, thereby causing a serious unpleasant feeling.

SUMMARY OF THE INVENTION The present invention has been conceived to solve these problems, and it is an object of the present invention to provide an upper panel and a lower panel which are rotatable inside a rotating frame, And a light shielding switching type optical shelf device in which the lower panel can be operated, and a structure provided with the optical shelf device.

Although the terms used in the present invention have been selected as general terms that are widely used at present, there are some terms selected arbitrarily by the applicant in a specific case. In this case, the meaning described or used in the detailed description part of the invention The meaning must be grasped.

Hereinafter, the technical structure of the present invention will be described in detail with reference to preferred embodiments shown in the accompanying drawings.

However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Like reference numerals designate like elements throughout the specification.

Referring to FIGS. 4 and 5, the light shielding switching type optical shelf unit 100 according to an embodiment of the present invention is driven to correspond to a change in altitude and position of the sun, And includes a frame 110, an upper panel 120, a lower panel 130, and an interlocking portion 140. [

The frame 110 is a frame rotatably mounted on a window frame or a door frame of a building around a frame rotation axis 111, which is a rotation axis in the vertical direction y.

For example, the frame 110 may be hinged so as to be openable to the inside of the window frame or the door frame.

The upper panel 120 is installed to be rotatable in an upper portion of the inside of the frame 110.

Here, the upper panel 120 is rotated about the upper panel rotation axis 121, which is a rotation axis of the horizontal direction (x) provided on the inner upper side of the frame 110.

One surface 122 of the upper panel is provided with a material for reflecting incident sunlight and the other surface 123 is made of a material for absorbing incident sunlight.

For example, a mirror may be attached to one side of the upper panel, and a black resin film may be attached to the other side of the upper panel.

Since the upper panel 120 is rotated about the upper panel rotation axis 121, when the sunlight is incident on one surface 122 of the upper panel, the upper panel 120 can be operated as a light shelf, 123), it can be operated as a louver.

In addition, a plurality of the upper panels 120 may be provided to control the degree of sunlight entering the room by varying an area reflecting incident sunlight.

Here, the lower panel 130 is rotated around a lower panel rotation axis 131, which is a rotation axis of a horizontal direction (x) provided at an inner lower portion of the frame 110.

In addition, both surfaces 132 and 133 of the lower panel are provided with materials for absorbing sunlight.

This is because, unlike the upper panel 120, the lower panel 130 operates only as a louver that blocks incident sunlight.

Hereinafter, the driving of the light shelf and the louver of the light blocking switching type light scanning device 100 according to the present invention will be described in detail.

The upper panel 120 and the lower panel 130 are laid down in the horizontal direction when the upper panel 120 of the light blocking switching type optical shelf unit 100 according to the present invention is driven by the light shelf, One side of the panels 120 and 130 faces the sunlight.

That is, when the panels 120 and 130 are laid down in the horizontal direction, one surface 122 of the upper panel reflecting the sunlight and one surface 132 of the lower panel absorbing sunlight are directed toward sunlight.

At this time, the upper panel 120 reflects incoming sunlight to a ceiling of a building, thereby introducing natural light, and the lower panel 130 absorbs incoming sunlight.

Accordingly, when the panels 120 and 130 are laid down in the horizontal direction and sunlight is directed, the upper panel 120 operates as a light shelf, and the lower panel 130 operates as a louver.

In addition, the upper panel rotation shaft 121 is preferably installed at a height of 1800 mm or more from the floor of the interior of the building.

This is because the upper panel 120, which rotates about the upper panel rotation axis 121 as a center axis, prevents direct sunlight from entering into the eyes of the user inside the building, thereby preventing the user from glare It is for this reason.

The upper panel 120 and the lower panel 120 may be vertically arranged in the vertical direction when the upper panel 120 of the light shielding switching type light scanning device 100 according to the present invention is operated as a louver, The other side of the panels 120 and 130 faces the sunlight.

That is, when the panels 120 and 130 are raised in the vertical direction, the upper surfaces of the upper panel and the lower surfaces of the lower panel, which absorb sunlight, are directed toward sunlight.

At this time, the other surface of the upper panel 120 and the lower panel 130 functions as a louver because it absorbs incoming sunlight and blocks sunlight from entering the room.

That is, when the panels 120 and 130 are vertically oriented and sunlight is directed, the upper panel 120 and the lower panel 130 operate as vertical louvers.

In addition, since the upper panel 120 and the lower panel 130 absorb sunlight to be introduced, sunlight is reflected on an outside pedestrian and the like, and damage can be prevented.

As described above, the light shielding switching type optical shelf unit 100 according to the present invention is a structure in which the upper panel 120 and the lower panel 130 can rotate around rotational axes in the horizontal direction (x).

Accordingly, the upper panel 120 operates as a light shelf and reflects incoming sunlight to a ceiling of a building, and the lower panel 130 operates as a louver to absorb sunlight, The sunlight is not directly exposed to the user, and the user's glare can be prevented.

In addition, the upper panel 120 and the upper lower panel 130 can be operated as a louver, and sunlight entering a room of a building can be blocked.

The interlocking portion 140 allows the frame rotation shaft 111, the upper panel rotation shaft 121 and the lower panel rotation shaft 131 to rotate in synchronization with each other. The first bevel gear 141, Two bevel gears 142, a third bevel gear 143 and a fourth bevel gear 144.

Referring to FIG. 6A, the first bevel gear 141 is provided on the frame rotating shaft 111 and is rotated together with the frame rotating shaft 111.

The third bevel gear 143 is provided on the upper panel rotation shaft 121 so as to be engaged with the first bevel gear 141. When the first bevel gear 141 rotates, 121).

6B, the second bevel gear 142 is separated from the first bevel gear 141 and is provided on the frame rotating shaft 111, and is rotated together with the frame rotating shaft 111.

The fourth bevel gear 144 is provided on the lower panel rotary shaft 131 so as to be engaged with the second bevel gear 142. When the second bevel gear 132 rotates, 131).

That is, when the frame 110 is rotated, the upper panel 120 and the lower panel 130 are simultaneously rotated.

Accordingly, the photovoltaic conversion type light shelf device 100 according to the present invention can easily control the degree of mining of the room according to the altitude, position change, or seasonal change of the sun.

In addition, the angle of rotation of the panels 120 and 130 can be adjusted so that the incident light and the panels 120 and 130 correspond more easily to each other in the light shielding switching type optical shelf apparatus 100 according to the present invention.

Each of the panel rotation shafts 121 and 131 rotates while being fixed to the frame 110 at one end.

In addition, the panel rotating shafts 121 and 131 may be provided with hinges so that they can be bent at predetermined positions.

Preferably, the hinge portion is located at a central portion of the panels 120 and 130, and minimizes the movement of the panels in the vertical direction when the panels 120 and 130 are rotated, The angle can be maximized.

For example, as shown in FIG. 7A, one end of the lower panel rotation shaft 131 is coupled to the frame rotation axis 111, and rotates while being fixed to the frame 110.

A portion of the lower panel rotation shaft 131 from the hinge portion 131a to one end of the lower panel rotation shaft 131 is coupled with the groove of the lower panel 130 so that the lower panel rotation axis 131 is coupled to the lower panel 130 It is possible to improve the appearance by preventing exposure to the outside.

Meanwhile, the upper panel rotation shaft 121 is also provided in the same manner as the lower panel rotation shaft 131 only in a position fixed to the frame 110. [

7B, the other ends of the panel rotation shafts 121 and 131 may be vertically movable along the frame 110. [

Here, the frame may further include a cylinder to move the other end of the panel rotation shafts 121 and 131 up and down.

At this time, the cylinder may be a pneumatic cylinder, a hydraulic cylinder, or the like, but is provided with a hydraulic cylinder in the present invention.

7C, the panel rotating shafts 121 and 131 are respectively provided with a plurality of bodies slidingly coupled to each other, and the length thereof can be varied.

This is to cope with variable lengths when the other ends of the panel rotation shafts 121 and 131 are movable up and down along the frame 110.

That is, as shown in FIG. 8, since the upper panel 120 or the lower panel 130 can easily rotate in response to a change in the sun altitude during the summer season and the winter season, it is possible to maximize the mining efficiency or the light- .

At this time, the bending range in which the panels 120 and 130 are rotated is preferably within 20 degrees.
