3 is a front view of the present invention, Figure 4 is an exploded perspective view of the present invention.

As shown, the present invention is a light diffuser 100 for diffusing light to the front and its peripheral portion to emit light, the lighting unit 200 for producing light to the light diffuser 100 to produce a variety of colors, the light It is configured to include a bracket 300 that is a support means for supporting the diffusion portion 100.

When the components are further subdivided, the light diffusing unit 100 is formed by joining three first and second floodlight plates 110, 120, and third floodlight plates 130 back and forth (however, In the present embodiment, for convenience of description, three floodlight plates 110, 120, and 130 are bonded to each other. However, the floodlight panels 110, 120, and 130 may be bonded in various numbers.) The same is not the same for the plurality of floodlights 110, 120, and 130, respectively. Different types of light diffusion patterns 111, 121, and 131 are engraved. Therefore, when the plurality of floodlight panels 110, 120, 130 are bonded together back and forth, when viewed from the front, each of the light diffusion patterns 111, 121, and 131 forming the divided pattern is combined to form a complete design. Light diffusion patterns 111, 121, and 131 engraved on the floodlights 110, 120, and 130 will be described in detail later.

The lighting unit 200 is provided with a plurality of LEDs 211, 213, and 215 in clusters of three columns corresponding to the number of the floodlight plates 110, 120, and 130. In addition, the LEDs 211, 213, and 215 are planted and installed, and an LED substrate 220 including a controller (not shown) for controlling the LEDs 211, 213, and 215 is installed. Here, the LEDs 211, 213, and 215 belonging to each group are controlled by the controller and operated separately. In addition, one group of LEDs 211, 213, 215 is responsible for only one corresponding floodlight plate 110, 120, 130 to supply light. That is, the first column LED 211 group is responsible for the first floodlight panel 110 to project light. The second row of LEDs 213 are in charge of the second floodlight panel 120 to project light. The third row of LEDs 215 is in charge of the third floodlight panel 130 to project light.

The support means is provided with a bracket 300 in the form of a square container, the top of which is open to support the lower ends of the floodlight panels 110, 120, 130. The LED substrate 220 is mounted on an inner bottom portion thereof.

In addition, the reflective frame 240 is installed on the remaining circumferential surface of the floodlight plate 110, 120, 130, the illumination unit 200 is not installed. The reflective frame 240 has a reflective surface formed therein to prevent light from projecting through the cross-sections of the transmissive plates 110, 120, and 130 in the direction in which the lighting unit 200 is not installed, while the light diffusion pattern ( 111, 121, 131) will be sent back to where it is. As a result, the luminous efficiency can be further increased.

The effect that the joining work becomes unnecessary can also be expected. The reflective frame 240 may be formed of various materials such as stainless steel or a thin synthetic resin coated with a reflective surface.

5 is an exploded perspective view partially disassembled to explain the light diffusion unit according to the present invention.

As illustrated, different types of light diffusion patterns 111, 121, and 131 are engraved on each of the floodlight plates 110, 120, and 130. Referring to the drawings, a blue taiji pattern and a light diffusion pattern 111 having a narrow border line are engraved on the first floodlight panel 110, and a red taiji pattern and a traditional pattern of red color are engraved on the second floodlight panel 120. It is seen that the light diffusion pattern 121 is engraved, and the third floodlight plate 130 is engraved with a blue taiji pattern and a wide border line. As such, the light diffusion patterns 111, 121, and 131, which are divided and engraved into each of the light transmitting plates 110, 120, and 130, are combined and overlapped with each other to form a completed pattern (see FIG. 3).

As such, when the light diffusion patterns 111, 121, and 131 are engraved on the plurality of floodlights 110, 120, and 130 by type, the light diffusion patterns 111, 121, and 131 may diffuse light of different colors to each part of the pattern at the same time. That is, the light of the color emitted from the first column LED 211 is refracted forward by the light diffusion pattern 111 of the first type through the first floodlight panel 110 to be diffused. At the same time, the light of the color emitted from the second row LED 213 group is refracted forward by the second type of light diffusion pattern 121 and diffused on the second floodlight panel 120. In addition, the light of the color emitted from the third column LED 215 group is refracted forward by the third type light diffusion pattern 131 on the third floodlight panel 130 to be diffused. Thus, light of three colors is simultaneously diffused forward by the light diffusion patterns 111, 121, and 131 for each type.

Here, the light diffusion patterns 111, 121, and 131 may be provided in various types of intaglio and emboss, such as V-cut, by laser cutting or silk printing. The light diffusion patterns 111, 121, and 131 may adjust the shape and the region to be formed depending on how much light is emitted toward the front. Accordingly, the light diffusion patterns 111, 121, and 131 may be used to produce a soft and soft atmosphere or a strong and clear atmosphere.

Here, the present invention makes it possible to emit more colors of light forward by having a larger number of floodlight plates by the same principle described above. In addition, the floodlight panel 110, 120, 130 may be configured as a variety of materials having a transparent and strength to meet the purpose of use. Usually, it is suitable as it is glass or an acrylic material, and lexan (polycarbonate).

6 is a partial perspective view illustrating the lighting unit according to the present invention, and FIG. 7 is a cross-sectional view taken along line AA ′ of FIG. 3.

As shown, the lighting unit 200 according to the present invention, in order to project the light of the desired color for each of the floodlight panel (110, 120, 130), the lower end of each floodlight (110, 120, 130) (or the left end of the floodlight plate, if necessary, A plurality of LEDs 211, 213, and 215 are installed side by side along the right side and the upper side. In the present exemplary embodiment, the first row LED 211 group, the second row LED 213 group, and the third row corresponding to the first flood plate 110, the second flood plate 120, and the third flood plate 130 are provided. A group of column LEDs 215 is installed on the substrate 220. Furthermore, LEDs of red, green, and blue colors are alternately arranged in one group of LEDs 211, 213, and 215 so as to project light of a desired color toward the corresponding floodlight panels 110, 120, and 130. . In this way, when the red, green, and blue LEDs 211, 213, and 215, which form three primary colors of light, are installed in one group, various colors of light may be realized depending on which of the LEDs is lighted. Therefore, one LED group may project light of at least nine colors, including three single colors of red, green, and blue, and six mixed colors of two, respectively, to the floodlight panels 110, 120, and 130, respectively. Then, even if only three floodlight panels 110, 120 and 130 are bonded, at least 729 (9 ³ ) colors can be produced in front.

When using the LED (211,213,215) as a light source for projecting light on the floodlight (110, 120, 130) as described above, it is possible to significantly reduce the power consumption compared to the conventional light sources such as fluorescent or neon light and ensure a long lifetime. .

Here, the color of the LED installed in the lighting unit 200 is not limited to red, green, and blue, but may be provided in various colors as necessary.

In addition, instead of the LEDs 211, 213 and 215 having intrinsic colors, the lighting unit 200 may use various light sources capable of emitting light of different colors from time to time such as discolored LEDs, optical fibers, neon lights, and the like. However, the optical fiber is provided with a separate light source and is simply a medium that transmits and emits the light, but is considered to include a separate light source.

The bracket 300 is formed in the shape of a rectangular container and the fixing projections 310 fixed to the inner front and rear surfaces by biting the lower ends of the floodlight (the first floodlight 110 and the third floodlight 130) from both sides. Protrudes in the form of a pointed mountain; As such, when the fixing protrusion 310 is formed, the bracket 300 and the floodlight plates 110, 120, and 130 are more firmly coupled to prevent the separation of the floodlights 110, 120, and 130, and a sense of unity is added to each other. On the other hand, the deepest bottom portion of the bracket 300 is provided with a lighting unit 200 including a plurality of LED (211,213, 215) group and the LED substrate 220.

Here, the bracket 300 may be installed to support the upper end or the left and right ends as well as the lower end of the floodlight (110, 120, 130). This depends on what the multicolor board of the present invention will be used for. For example, if the present invention is used as a fence installed outdoors, the bracket 300 may be preferably installed at upper ends of the floodlight plates 110, 120, and 130. This is because, in rainy weather, the bracket 300 may serve as a sunshade to prevent the inundation of the lighting unit 200 installed therein.

In addition, a reflective sheet 230 having both surfaces formed of reflective surfaces is provided between the transparent plates 110, 120, 130 and one end of the transparent plates 110, 120, 130. When the reflective sheet 230 is installed as described above, light emitted from one LED group 211, 213, and 215 is projected onto the light transmitting plates 110, 120, and 130, and then, may be suppressed from penetrating into other surrounding light transmitting plates and mixing.

The operation of the multi-colored light emitting board according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, when power is applied, the control unit of the LED substrate 220 operates to control the plurality of LED groups 211, 213, and 215, respectively. Accordingly, the LEDs 211, 213, and 215 of each group emit light of the color indicated by the control panel toward the floodlight plates 110, 120, and 130 in charge. For example, the first group of LEDs 211 illuminates the red and blue colors of the LEDs 211 and 215 to project the mixed red and blue colors onto the first floodlight panel 110, and the second group of LEDs ( 213 lights only the red LED 215 to project red light, and the third group lights up the green and blue LEDs 213 and 215 at the same time to emit mixed green and blue light Project onto plate 130. The light projected on the lower ends of the floodlights 110, 120, and 130 is then directed upward through the interior of the floodlights 110, 120, and 130. On the other hand, immediately after being projected by the light emitting plate (110, 120, 130) in the LED (211, 213, 215) group, some of the light toward another adjacent light emitting plate (110, 120, 130) is reflected by the reflective sheet 230 to change the course again to go in the correct direction.

Subsequently, light traveling upward from the inside of the floodlight panels 110, 120, and 130 meets the light diffusion patterns 111, 121, and 131 formed in the middle of the floodlight panels 110, 120, and 130. As a result, light is refracted and diffused in front of and around the floodlights 110, 120, and 130. As a result, when viewed from the front, the light diffusion patterns 111, 121, and 131 engraved in a desired shape are beautifully emphasized by the bright and soft light as if the light of the subtle color is formed. In this case, the light diffusion patterns 111, 121, and 131 that emit light of different colors are combined and combined, and at the same time, the overall pattern of light of various colors is prominently displayed to the outside.

Subsequently, the color of the light emitted forward through the light diffusion patterns 111, 121, and 131 from the floodlights 110, 120, and 130 is changed from time to time by the instruction of the controller, thereby creating a beautiful and subtle visual effect that is noticed even in the distance at night. .
