Description

Light emitting roll blind using optical fiber and its control method {LIGHT EMITTING ROLL-BLIND USING OPTICAL FIBER AND METHOD FOR CONTROLLING THE SAME}

The present invention relates to a luminescent roll blind and its control method. In particular, it relates to a roll blind configured to emit light using or including an optical fiber and a method of controlling a luminescent roll blind.

Blinds are a general term for items installed on windows to block sunlight. Light blocking blinds can be classified into vertical blinds, venetian blinds, roll blinds, etc. depending on their shape. Among these, roll blinds mean that a screen for blocking light is wound around a winding roll to adjust the length, and is also called a roll screen.

In general, conventional roll blinds adjust the degree of opening and closing by adjusting the vertical length of the screen wound on a winding roll or a winding rod. In other words, if the screen is sufficiently unwound and sufficiently covers the window, the sun can be blocked, and if the screen is wound and rolled up, the window can be exposed.

Meanwhile, products called combination blinds or double blinds are being commercialized. Combi blinds are composed of a double screen to cover the window, but the screen has a part with high light transmittance and a part with low light transmittance. The light transmitting part with relatively high light transmittance and the light blocking part with low light transmittance are arranged alternately in a stripe pattern, and the degree of light transmission can be adjusted by using the arrangement of the light transmitting part and the light blocking part.

Republic of Korea Patent Publication No. 10-2019-0066121, Combi Double Blind

One of the reasons the aforementioned combination blinds are attracting attention is that they can provide a significant sense of openness without having to completely roll up the screen. In other words, even when the screen completely covers the window, sunlight can pass through when the two light transmitting parts arranged in a double manner overlap.

In addition, the two double-arrayed light transmitting parts overlap to create a feeling of considerable openness indoors, while the striped pattern-shaped light blocking part reduces visibility of the indoor space from outdoors, thereby improving privacy.

Figure 2 is an enlarged perspective view showing the area near the bracket and winding roll of Figure 1. Figure 3 is an enlarged perspective view showing the vicinity of the weight bar in Figure 1. Figure 4 is a side cross-sectional view showing the combined state of the screen, winding roll, and bracket of Figure 1. For clarity of illustration, the light source is not shown in Figure 1. Figure 5 is a perspective view of the screen of Figure 1 in an unfolded state. Figure 6 is a bottom perspective view of the screen of Figure 5 turned upside down.

Referring to Figures 1 to 6, the roll blind 11 according to this embodiment includes a bracket 300, a winding roll 400, a screen 100, and a light source (not shown), and the winding roll 400 It may further include a lifting wire 500 and a weight bar 600 that rotate.

The bracket 300 may be a structure fixed to the wall or ceiling, or near the chassis of a window, for installation of the roll blind 11. The bracket 300 may be made of a metal material with excellent strength. Although not shown in the drawing, the bracket 300 may be fixed to a wall or ceiling using screws, etc., or may be configured to be inserted into a clip fixed to the wall or ceiling.

The winding roll 400 may be placed inside the bracket 300. For example, the winding roll 400 may rotate within a plane to which the first direction (X) and the third direction (Z) belong to wind up or unwind the screen 100, which will be described later. A lifting wire 500 may be used to rotate the winding roll 400. The lifting wire 500 has a wire shape extending in approximately one direction, but may have a closed loop shape with one end and the other end connected. Additionally, the lifting wire 500 may include a plurality of beads spaced apart at a predetermined distance and may be configured to rotate the teeth of the winding roll 400 using the beads. Since the rotation principle of the winding roll 400 using the lifting wire 500 can be used as a known principle, detailed description will be omitted.

In an exemplary embodiment, the roll blind 11 according to this embodiment may be a double blind or a combination blind in which the screen 100 forms an approximately 'U' shape from a side view. That is, the screen 100 can be fixed at both ends 102a and 102b not only to the winding roll 400 but also to the bracket 300.

While both ends 102a and 102b of the screen 100 are fixed to the bracket 300 and the winding roll 400, a portion near the longitudinal center of the screen 100 may sag downward due to gravity. At this time, a weight bar 600 can be used so that the screen 100 can be hung flat. The screen 100 is inserted into the weight bar 600, and the central portion of the screen 100 is saggy using the weight of the weight bar 600 to form a curved portion of the screen 100.

At this time, the screen 100 at the portion connecting the winding roll 400 in the curved portion formed by the weight bar 600 is located on the user side or the indoor side facing the roll blind 11, and is located on the front screen 100a. It may be referred to as . On the other hand, the screen 100 at the curved portion connecting the bracket 300 is generally located on the window side and may be referred to as the rear screen 100b. That is, the curved screen 100 can be overlapped between the user and the window, and the front screen 100a can be positioned between the rear screen 100b and the user. However, of course, the front screen 100a and the rear screen 100b may change depending on the rolling state of the screen 100.

One end 102a (or first end) of the screen 100 may be fixed to the bracket 300, and the other end 102b (or second end) may be fixed to the winding roll 400. At this time, with the screen 100 rolled down to its lowest position, a portion adjacent to one end 102a of the screen 100, for example, one end 102a relative to the center in the longitudinal direction (L) of the screen 100. ) side forms at least the rear screen 100b, and a portion adjacent to the other end 102b, for example, the other end 102b side with respect to the center in the longitudinal direction (L), is arranged to form at least the front screen 100a. You can.

Additionally, the other end 102b of the screen 100 may be coupled to the winding roll 400 through the space between the winding roll 400 and a fixing part of the bracket 300 that fixes the one end 102a. In other words, the screen 100 referenced in FIG. 4 may be wound clockwise on the winding roll 400. Through this, the separation distance between the front screen 100a and the rear screen 100b in the first direction (X) can be reduced, and light blocking characteristics using the low light transmitting portion 110, which will be described later, can be improved. If, unlike in Figure 4, the screen is wound counterclockwise on the winding roll, the separation distance between the front screen 100a and the rear screen 100b in the first direction (X) is the first direction (X) of the winding roll. The width may increase, and the light blocking characteristics may deteriorate.

Meanwhile, the screen 100 may include a high light transmittance portion 130 and a low light transmittance portion 110, or the high light transmittance portion 130 and the low light transmittance portion 110 may be defined. The high light transmittance portion 130 may be a portion with relatively high light transmittance, and the low light transmittance portion 110 may be a portion with relatively low light transmittance. For example, the light transmittance of the high light transmitting portion 130 is about 40% or more, or about 50% or more, or about 60% or more, or about 70% or more, or about 80% or more, or about 90% or more, or about It may be more than 95%. Additionally, the light transmittance of the low light transmitting portion 110 is about 50% or less, or about 40% or less, or about 30% or less, or about 20% or less, or about 10% or less, or about 5% or less, or about 1% or less. It may be below.

The high light transmittance portion 130 and the low light transmittance portion 110 may each have a stripe pattern shape extending in the second direction (Y). The high light transmittance portion 130 and the low light transmittance portion 110 may be alternately arranged along the longitudinal direction (L) of the screen 100. Using this, the arrangement of the high light transmittance portion 130 and the low light transmittance portion 110 can be changed depending on the degree of winding of the screen 100 and allow light to pass through the high light transmittance portion 130 or the low light transmittance portion 110. The transmission of light can be at least partially blocked using . Figure 5 and other examples illustrate a case where a total of 10 low-transmissive parts 110 are arranged along the longitudinal direction (L) of the screen 100, but of course, the present invention is not limited thereto. Hereinafter, the plurality of low-transmission parts 110 arranged in the longitudinal direction (L) are sequentially formed from the first low-transmission part 111 to the tenth low-transmission part 120 in the direction from one end 102a to the other end 102b of the screen 100. ).

In this specification, the longitudinal direction (L) may refer to the longitudinal direction of the screen 100. When the screen 100 is installed, the longitudinal direction L may be at least partially parallel to the third direction Z or the direction of gravity. On the other hand, the width direction (W) of the screen 100 may face the second direction (Y). Additionally, the thickness direction (T) of the screen 100 may face the first direction (X).

One or more light sources 200 may be disposed on the screen 100. The light source 200 may be fixed on the outer surface of the screen 100, or may be interposed, that is, embedded, between the screen 100 when it is composed of multiple layers. In this specification, the arrangement of the light source 200 on the screen 100 is a concept that includes all of these.

In an exemplary embodiment, the light sources 200 may be disposed only on the low-transmission portion 110 of the screen 100. On the other hand, the light sources 200 may not be disposed on the high light transmitting portion 130 of the screen 100. In this case, the light source 200 may be arranged to overlap the low transmissive part 110 in the thickness direction (T), but may not overlap the high transmissive part 130 in the thickness direction (T).

In addition, at least some of the light sources 200, for example, the first light source 210, are arranged to emit light toward the first side 101a (or one side) of the screen 100, and at least another part of the light sources 200 , for example, the second light source 220 may be arranged to emit light toward the second side 101b (or the other side) of the screen 100. When one end (102a) and the other end (102b) of the screen 100 are coupled to the bracket 300 and the winding roll 400, respectively, the first surface 101a is the inner surface of the hanging screen 100. , the second surface 101b may be the outer surface of the hanging screen 100. That is, a user looking at the roll blind 11 may look at the outer side of the front screen 100a and the inner side of the rear screen 100b. On the other hand, the inner surface of the front screen 100a and the outer surface of the rear screen 100b may face the window.

In an exemplary embodiment, light source 200 may include an optical fiber. An optical fiber is a general term for an object that extracts transparent glass or synthetic resin such as silicon in a linear form and guides light through its interior. The optical fiber may be fixed on the screen 100 by a method such as stitching, but of course, the present invention is not limited thereto. The optical fiber has high flexibility and may not be damaged even in situations such as when the screen 100 is wound on the winding roll 400.

Additionally, while other light sources, such as LED devices, require components such as a substrate in the vicinity of directly emitting light, optical fibers can transmit light far from the vicinity of directly emitting light. The present invention is not limited to this, but in this embodiment, the part that directly emits light is included in the control module 700, which will be described later, and the light source 200 guides the light received from the control module 700 to provide It may refer to the part that provides a luminous effect to the user. That is, the light source 200 may receive light through the optical path portions 210a and 220a, and the light source 200 and the optical path portions 210a and 220a may be formed integrally like an optical fiber.

The roll blind 11 according to this embodiment includes a light source 200 disposed on the low light transmitting portion 110 of the screen 100, so that the roll blind 11 not only provides a light blocking function, but is also visible to the user. The light source 200 can be used to provide a function as interior lighting as needed.

Hereinafter, the arrangement relationship between the screen 100 and the light source 200 will be described in detail. Figure 7 is a cross-sectional view of the screen on which the light source is disposed.

Referring further to FIG. 7 , the light source 200 according to this embodiment may include a first light source 210 and a second light source 220. The first light source 210 may be disposed on the first side 101a of the screen 100. Additionally, the second light source 220 may be disposed on the second side 101b of the screen. As described above, the first surface (101a) is the inner surface and the second surface (101b) is the outer surface.

Additionally, a plurality of first light sources 210 may be arranged in the longitudinal direction (L). The plurality of first light sources 210 arranged from one end 102a to the other end 102b of the screen 100 are sequentially referred to as 1-1 light sources 211 to 1-5 light sources 215. That is, the 1-1st light source 211 may be disposed closer to one end 102a than the 1-5th light source 215.

The first light source 210 may be disposed closer to one end (102a) of the screen 100 than to the other end (102b). As a non-limiting example, the first light source 210 may be disposed only on one end 102a side based on the center of the longitudinal direction L of the screen 100, or a greater number may be disposed on one end 102a side. . As another example, among the plurality of first light sources 210, the first light source 210 closest to the other end 102b, that is, the 1-5 light sources 215, is located closer to one end 102a than the other end 102b. Can be placed close together.

Likewise, a plurality of second light sources 220 may be arranged in the longitudinal direction (L). The plurality of second light sources 220 arranged from one end 102a to the other end 102b of the screen 100 are sequentially referred to as 2-1st light sources 221 to 2-7th light sources 227. That is, the 2-1st light source 221 may be disposed closer to one end (102a) than the 2-7th light source 227.

In addition, among the plurality of second light sources 220, the second light source 220 is disposed on the other end 102b side rather than the second light source 220 disposed on one end 102a side based on the center of the longitudinal direction L. The number may be more. As another example, among the plurality of second light sources 220, the second light source 220 closest to the other end 102b, that is, the 2-7th light source 227, is closer to the other end 102b than the one end 102a. can be placed. On the other hand, among the plurality of second light sources 220, the second light source 220 closest to the one end (102a), that is, the 2-1 light source 221, will be placed closer to one end (102a) than the other end (102b). You can.

In some embodiments, the number of second light sources 220 may be greater than the number of first light sources 210.

In some embodiments, at least some of the first light sources 210 and the second light sources 220 may be arranged to overlap in the thickness direction T, and other parts may be arranged not to overlap.

Specifically, the 1-1 light source 211 is disposed on the first low-transmission portion 111, the 1-2 light source 212 is disposed on the second low-transmission portion 112, and the third low-transmission portion 113 The first to third light sources 213 may be disposed on the image. On the other hand, the second light source 220 may not be located on the first low-transmission part 111 to the third low-transmission part 113. In this way, the area where the light source is placed only on the first surface 101a defines the first area BA1.

Additionally, the 1-4th light source 214 and the 2-1st light source 221 may be disposed on the fourth low light transmitting portion 114. The 1-4th light source 214 and the 2-1st light source 221 may be spaced apart from each other with the fourth low-transmission portion 114 of the screen 100 interposed therebetween. Likewise, the 1-5 light source 215 and the 2-2 light source 222 may be disposed on the fifth low light transmitting portion 115. The 1-5th light source 215 and the 2-2nd light source 222 may be spaced apart from each other with the fifth low-transmissive portion 115 of the screen 100 interposed therebetween. In this way, the area where the light source is disposed on both the first surface 101a and the second surface 101b defines the second area BA2.

Additionally, the 2-3rd light source 223 is disposed on the sixth low-transmission portion 116, the 2-4th light source 224 is disposed on the seventh low-transmission portion 117, and the 2nd-4th light source 224 is disposed on the eighth low-transmission portion 118. The 2-5 light source 225 is disposed, the 2-6th light source 226 is disposed on the 9th low-transmission portion 119, and the 2-7th light source 227 is disposed on the 10th low-transmission portion 120. You can. On the other hand, the first light source 210 may not be located on the sixth low-transmission part 116 to the tenth low-transmission part 120. In this way, the area where the light source is placed only on the second surface 101b defines the third area BA3.

Among the above-described plurality of first light sources 210 and second light sources 220, light sources arranged overlapping each other in the thickness direction (T), specifically, the 1-4 light source 214 and the 2-1 light source 221 , both the 1-5 light source 215 and the 2-2 light source 222 may be located closer to the end 102a. That is, the above-described light sources 200 may be disposed on one end 102a side of the screen 100 based on the center in the longitudinal direction (L).

As described above, the control method of the roll blind 11 according to the present embodiment is based on the sensor 800, for example, the gyro sensor G, depending on the roll-up and/or roll-down state or position of the screen 100. In other words, the light sources 200 can be partially sequentially turned on or off according to a predetermined standard of the rolling state of the screen.

That is, the first light source 210 disposed only on the rear screen 100b and turned on in the most rolled-down state, that is, the first light source 210 turned on in the first area BA1 and the second area BA2 is the screen. As 100 is rolled up, the light may be turned off sequentially from the 1-5 light source 215 closest to the other end 102b to the 1-1 light source 211 furthest from the other end 102b. Conversely, as the screen 100 rolls down, it may turn on sequentially from the 1-1st light source 211 to the 1-5th light source 215.

In addition, the second light source 220, which is disposed only on the front screen 100a and illuminated in the most rolled-down state, that is, the 2-3 light sources 223 to 2-7 light sources 227, that is, the third area BA3 ) As the screen 100 rolls up, the illuminated second light source 220 changes from the 2-7 light source 227 closest to the other end 102b to the 2-3 light source furthest from the other end 102b ( 223) can be eliminated sequentially.

It can light up sequentially in each direction. Conversely, as the screen 100 rolls down, the light may turn off sequentially from the 2-1 light source 221 to the 2-2 light source 222.

In another embodiment, sensor 800 may include a rotation speed sensor (not shown). The rotation speed sensor can measure the rotation speed of the winding roll 400. For example, the rotation speed sensor measures the number of rotations when the winding roll 400 rotates to wind the screen 100, based on the state in which the screen 100 is not rotated on the winding roll 400. You can. For example, if the circumference of the winding roll 400 is about 10 cm and the repetitive pitch of the low light transmitting part 110 is about 30 cm, it can be determined that the winding roll 400 has been rolled up by one pitch length when it rotates 3 times. . Using this, the rolling state of the screen 100 can be determined, and the blinking operation of the light sources 200 can be controlled based on this.

Referring to FIG. 15, the roll blind 12 according to this embodiment includes a screen and light sources 213, 214, 215, 221, 222, and 223 disposed on the screen, and the screen is made of a plurality of layers. , The difference from the above-described embodiment is that the light source is disposed between the screen and the screen.

In an exemplary embodiment, the screen may include a first transmissive layer 191, a second transmissive layer 192, and a light blocking layer 113, 114, 115, and 116 stacked together. The light blocking layers 113, 114, 115, and 116 may have a stripe pattern shape extending in the width direction (W). Additionally, a plurality of light blocking layers 113, 114, 115, and 116 may be arranged to be spaced apart in the longitudinal direction (L). 15 shows that the light blocking layers 113, 114, 115, and 116 include a third light blocking layer 113, a fourth light blocking layer 114, a fifth light blocking layer 115, and a sixth light blocking layer 116. Although only the dog is shown, it goes without saying that the present invention is not limited thereto.

The light transmittance of the light blocking layers 113, 114, 115, and 116 is about 50% or less, or about 40% or less, or about 30% or less, or about 20% or less, or about 10% or less, or about 5% or less, Or it may be about 1% or less. That is, in this embodiment, the light blocking layers 113, 114, 115, and 116 are used not only to have complete light blocking characteristics but also to include layers with relatively low light transmittance.

A first transmissive layer 191 and/or a second transmissive layer 192 may be disposed on the upper or lower surfaces of the light blocking layers 113, 114, 115, and 116. The light transmittance of the first transparent layer 191 and the second transparent layer 192 is each about 40% or more, or about 50% or more, or about 60% or more, or about 70% or more, or about 80% or more, or It may be about 90% or more, or about 95% or more.

The light blocking layers 113, 114, 115, and 116 spaced apart in the longitudinal direction (L) may define a light blocking area. On the other hand, an area where the light blocking layers 113, 114, 115, and 116 are not disposed may define a light transmitting area (TA). At this time, the light blocking area may be divided into a first area (BA1), a second area (BA2), and a third area (BA3).

As described above, within the first area BA1, the light source may be arranged to emit light only toward the first surface 101a. To this end, the light source in the first area BA1, that is, the first-third light source 213, is disposed on the first side 101a of the light blocking layers 113, 114, 115, and 116, and the third light blocking layer 113 ) and the light transmitting layer 190.

Additionally, within the second area BA2, the light source may be arranged to emit light toward both the first surface 101a and the second surface 101b. To this end, among the light sources in the second area BA2, the 1-4 light sources 214 and 1-5 light sources 215 are located between the fourth light blocking layer 114 and the first light transmission layer 191, respectively, and 5 It may be disposed between the light blocking layer 115 and the first light transmitting layer 191. In addition, among the light sources in the second area BA2, the 2-1st light source 221 and the 2-2nd light source 222 are located between the fourth light blocking layer 114 and the second light transmission layer 192, respectively, and the fifth light source 221 It may be disposed between the light blocking layer 115 and the second light transmitting layer 192.

Additionally, within the third area BA3, the light source may be arranged to emit light only toward the second surface 101b. To this end, the light source in the third area BA3, that is, the 2-3 light source 223, is disposed on the second side 101b of the light blocking layers 113, 114, 115, and 116, and the sixth light blocking layer 116 ) and the light transmitting layer 190.

Other components of the roll blind 12, such as the first light source, the second light source, and the control method using the sensor, have been described above, so redundant description will be omitted.

Roll blinds according to the present invention can provide a method of controlling the light source so that light is visible toward only one side, but not toward the other side. For example, light may be emitted toward the indoor side or the user side, but may not be emitted toward the window side or the outdoor side.

However, the present invention is not limited to this, and when the installation direction of the screen is changed, it can be configured to emit light toward the window but not toward the interior. In this case, especially when used in an office, etc., the screen can be rolled down indoors to block outdoor light, but can emit light outdoors. This can be used to provide a sign-like effect.

Although the above description focuses on the embodiments of the present invention, this is only an example and does not limit the present invention, and those skilled in the art will understand the present invention without departing from the essential characteristics of the embodiments of the present invention. It will be apparent that various modifications and applications not illustrated above are possible.

Therefore, the scope of the present invention should be understood to include changes, equivalents, or substitutes of the technical ideas exemplified above. For example, each component specifically shown in the embodiments of the present invention can be modified and implemented. And these variations and differences in application should be construed as being included in the scope of the present invention as defined in the appended claims.
