FIGS. 2A to 2C are front views illustrating a blind with an LED media facade function using a roll blind according to various embodiments of the present invention. FIG.
3 is a side sectional view showing a cross section of a part of a blind with LED panel facade function according to the present invention.
FIG. 4 is a front view showing a blind with an LED media facade function using a vertical superposition type blind according to the present invention; FIG.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2A to 2C show a first embodiment of the present invention. In this embodiment, the LED media facade function is implemented using a roll blind.

The present embodiment is configured to transmit and scatter light through an optical fiber installed in the roll blind 20.

A plurality of LED lamps 11 are installed in the left and right directions with an interval between the LED lighting units 10, which are bar-type lights installed on the ceiling. The LED lighting units 10 are disposed in front of the building, The light emitted from each of the LED lamps 11 transmits light through an end light type optical fiber, passes through an end light type optical fiber, passes through a side light type optical fiber The light is transmitted and scattered simultaneously.

LED bar-type lighting is an LED lamp (11) buried in a row, and there are oval type and SMD type depending on the type of LED lamp. Oval type LEDs are better than SMD type LEDs because of their straightness and brightness but they are embedded separately with red, green and blue colors so that the minimum color mixing distance is longer than that of SMD type LEDs. There are disadvantages. The SMD type LED has the shortest color mixing distance and simple structure, but it has a disadvantage that the straightness of light and the brightness are inferior because the color of red, green, have.

A roll blind 20 is coupled under the LED lighting unit 10. A housing for enclosing the lens and the light is installed below the LED lighting unit 10 so that when the light from the LED lamp 11 flows into the optical fiber, May be configured to collect light.

Since the finished product in which the LED lighting unit 10, the roll blind 20 and the optical fiber are combined is manufactured in the factory, the installer can complete the installation only by fixing the LED lighting unit 10 to the ceiling inside the building window have.

The term "optical fiber" refers to a fiber in the form of a double cylinder in which a portion called a core in the center surrounds a portion called a cladding in the periphery, and transmits light by a difference in refractive index between the core and the cladding.

Such an optical fiber is classified into an END light type and a SIDE light type depending on the light emitting type. The end-type type is a method in which light does not emit light in the passage but emits light only at the end. The side light type is a method of scattering light from the side of a passage while transmitting light.

In the first embodiment of the present invention, the first optical fiber unit 40, which is an end light type optical fiber installed on the front surface of the roll blind 20, After the light is transmitted, the roll blind 20 is used as a reflector through a second optical fiber unit 50, which is a sidelight type optical fiber connected to the distal end of the first optical fiber unit 40, )do.

The second optical fiber unit 50 may be arranged in a stair-step arrangement, a zigzag arrangement, or a spiral arrangement so as to efficiently constitute a surface light source.

Figs. 2A to 2C show various embodiments of the optical fiber attached to the front portion of the roll blind 20. Fig.

As shown in FIGS. 2A to 2C, it can be assumed that the front portion of the roll blind 20 has nine luminescent regions divided into a checkerboard pattern, and the boundary between the luminescent regions is indicated by a dotted line. It is preferable that the second optical fiber portion 50 is spread over the entire region of the light emitting region so that the light emitting region shines evenly throughout the entire region.

In the embodiment of FIG. 2A, the second optical fiber portion 50 has a circular vortex shape. One end of the first optical fiber unit 40 is directly connected to the LED lamp 11 and the other end of the first optical fiber unit 40 is connected to one end of the second optical fiber unit 50 to transmit light emitted from the LED lamp 11 to the second optical fiber unit 50, and the light is only passed through the inside and does not scatter out. The light passing through the first optical fiber unit 40 passes through the second optical fiber unit 50, so that the light is displayed gently.

The second optical fiber unit may use a conventional cylindrical shape, but may be a plate-like plate formed flat in the back-and-forth direction or a square-shaped prism having a polygonal cross-section perpendicular to the longitudinal direction.

In the embodiment of FIG. 2B, the segments of the second optical fiber unit 50, which are gradually reduced in size from the outside to the inside, are connected to each other at right angles to form a square swirl.

The embodiment of FIG. 2C is configured such that the second optical fiber part 50 is arranged in such a manner that line segments extending in the left-right direction are arranged side by side while being vertically downward, and vertically extending parts located at the left- It has a zigzag form and reciprocating right and left.

The first optical fiber unit 40 may be simply attached to the front surface of the roll blind 20 from the portion connected to the LED lamp 11 and may be downwardly connected to one end of the second optical fiber unit 50, And is disposed so as to pass the edge of the light emitting region so as not to intersect with the light emitting portion 50.

In the above embodiments, the optical fiber is attached to the roll blind 20 in various manners. However, in order to effectively adhere the optical fiber to the surface member of the roll blind 20 used as the reflector, the optical fiber is used as a warp or weft, The durability of the blind can be further enhanced by integrally fabricating the reflector and the optical fiber by weaving with the outer ply fabric.

A protective layer 60 for blocking ultraviolet rays may be entirely coated on the front surface of the roll blind 20 to which the optical fiber is attached to the front portion, as shown in FIG. Alternatively, ultraviolet absorber is added to the cladding portion of the optical fiber to protect it from direct sunlight during the daytime.

The protective layer 60 is also made of a transparent material to transmit the LED illumination light emitted from the second optical fiber unit 50 to the outside, because the protective layer 60 also serves to prevent dust from adhering to the surface of the roll blind 20.

The protective film (UV film) 60 is mainly composed of a polyester film or a polyethylene film. It is also possible to replace the protective layer by adding an ultraviolet absorber to the optical fiber itself.

Since the roll blind 20 used as a reflection plate is not a light transmission but a reflective function, it may be made of an opaque thin plate, and it is preferable that the roll blind 20 is made of a material which acts as a flame retardant layer in a fire in addition to total reflection.

FIG. 4 shows a second embodiment of the present invention. In this embodiment, a vertical blind 30 is used to implement the LED media facade function.

The vertical blind 30 has a structure in which a plurality of longitudinally elongated blades are hanged and each of the blades can be individually rotated.

The roll blind 20 used in the first embodiment has a drawback in that the roll must be raised and lowered in order to adjust the amount of light entering the room during the day. However, the vertical blind 30 used in the second embodiment Can control the amount of light entering the room by adjusting the angle of the blind wing so that it is not necessary to raise or lower the entire blind by day or night.

In other words, at night, the vertical blades forming the vertical blinds 30 are closed so that the light emitted from the optical fiber 2 optical fiber part 50 is directed to the outside of the building, and at the daytime, You do not have to repeat the whole blinds up and down because you can adjust.

The vertical blind 30 also functions as a planar light source in the same manner as the roll blind 20, and as shown in FIG. 4, three vertical, . In this case, each blind wing is provided with three light emitting regions capable of individual operations. In the case where the blind wing is long, it is possible to provide more light emitting regions for each wing, and a high-level high-resolution display is possible.

In the case where the blind wing constituting the vertical blind (30) is exposed to light even at the edge portions where the blind wings are partially overlapped, the light coming forward may strike the blind wing portion in front and cause a side effect to enter into the room. Of the blinds constituting the blind 30, the edge portions where the blind wings are overlapped forward and backward are provided at the end light portion of the optical fiber, that is, only the first optical fiber portion 40 is long in the vertical direction, The second optical fiber unit 50 is installed only in the remaining portion except for the overlapping portion of the second optical fiber unit 50 so that light is diffused forward.

Since the second optical fiber unit 50 is not provided at the end portion of the blind wing which can overlap the blind wing when it is coupled to the blind wing which is a surface light source, it is possible to display the image such that a part of the screen as a whole is not cut- It is possible.

The surface illuminations according to the first or second embodiment may be realized by a controller capable of individually controlling the LED lamp 11 so that each light emitting area is represented by one pixel in various images, It can play a big role in getting a status as a landmark that not only can be appreciated but also increases the value of buildings.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as set forth in the accompanying drawings. And modifications are within the scope of the appended claims.

The surface lighting realized by the blind according to the present invention is represented by pixels of various images by the control of the LED point light sources so that not only beautiful images and information can be transmitted, but also it is widely used to give a phase as a landmark for enhancing the value of buildings .
