Description

Sign with improved visibility}

The present invention relates to a signboard, and in detail, by attaching an LED assembly to a conventional signage to improve visibility, the LED assembly is covered with a light emitting part having a thin film light emitting part and a thick film light emitting part on the LED to prevent light from being scattered and The irradiation range is designated as the size of the light emitting part, and the thin film light emitting part can reach the far distance, while alleviating glare in front of the front of the LED. In the thick film light transmitting part, the medium is thick, so part of the light passing through the medium is reflected inside. The present invention relates to a signboard with improved visibility that maximizes the advertisement effect by improving the visibility of the signboard at a distance / near distance and front / side by allowing light to be transmitted to the side.

The signboard is a sign that can be hanged or attached to shops, companies, offices, institutions, etc. by writing its name, sales products, business items, etc., so that people can easily see it.

Signboards include rooftop signs, wall signs, bulge signs, store signs, signboards and billboards (signs placed on fields, mountains, and highways). Signboards can also be found in the area of traffic advertising, including in-vehicle advertising, off-board advertising, and stationary advertising (inside and outside of stations).

In today's society, various forms of signboards are appearing as commercial activities are complicated and competition among industries is fierce. Therefore, the signboard in modern society should be able to stand out from the crowd of signboards so that the contents to be delivered at a glance can be accurately and quickly delivered. For this purpose, a variety of light emitting bodies are attached to the signboard, among which LEDs are used a lot due to various advantages.

However, the biggest disadvantage of such LED is that the LED emits front light, so when looking at the LED directly in front of the LED, the brightness is high and there is a glare phenomenon, which makes the eye easily tired. Furthermore, when the letters are made by combining these LEDs, it is difficult to accurately recognize the letters due to the glare in front of the LEDs.

In addition, since the light emitted from the LED has a property of going straight, there is a problem that it is not easy to recognize it from the side because almost no light is transmitted to the side of the LED.

Therefore, in the case of a sign that expresses letters or figures by combining several LEDs, eyes are easily tired by the glare right in front of the LED and it is difficult to recognize the shape of the light emitting part. Since it is not easy to recognize, there is a case that it is difficult to recognize at a glance exactly what the signboard wants to convey.

Furthermore, the light emitting device using a conventional LED has a relatively narrow range in which one LED is irradiated due to the front emission of the LED and the linearity of the light emitted from the LED. Could be displayed and recognized at long range and near distance. However, in this case, since a large number of LEDs must be installed, the circuit configuration is complicated, installation costs, material costs, etc. are high, and maintenance costs are high and maintenance is difficult.

In addition, once the LED is installed on the signboard, the damaged LED must be replaced if it is damaged due to flying from the outside or falling down due to wind, etc.In order to replace it in the field, disassemble the entire LED assembly. There was an inconvenience to repair or replace with a new one.

Signboards should be able to deliver the contents they want to convey at a glance accurately and quickly, and should be able to be remembered for a long time by the person who saw them. For this purpose, signboards using LED emitters appeared. However, since the LED emits light in front and the light emitted from the LED goes straight, a relatively large amount of light arrives in front of the LED, causing glare, and the light emitted from the LED hardly reaches from the side. Signboards with LEDs may be difficult to recognize accurately and quickly. Furthermore, since the irradiation range of the LED is extremely limited, when it is necessary to illuminate a wide range, it is necessary to use a plurality of LEDs, and thus, installation costs and maintenance costs are high, and replacement is very inconvenient.

Hereinafter, the configuration and operation of an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the following examples are provided to enable those skilled in the art to fully understand the present invention, but the scope of the present invention is not limited by the embodiments described below.

1 is an exemplary view of a signboard improved visibility according to the present invention. As shown in FIG. 1, the signboard having improved visibility according to the present invention includes an LED assembly 100, a signboard body 200, a control unit 300, and a power supply unit 400.

Signboard body 200 is the body portion of the signboard according to the present invention, the signboard body 200 means that it is currently commonly called a signboard on the market, there is no particular limitation on this. Signboard body 200 is typically displayed to the contents to be delivered, LED assembly 100 should be able to be attached to the required portion. Specific examples of the signboard body 200 will be described in more detail in the following embodiments.

The LED assembly 100 is attached to the signboard body 200 at regular intervals. 2 is a cross-sectional view of the LED assembly used in the present invention. As shown in FIG. 2, the LED assembly 100 according to the present invention includes an LED 1, a light transmitting unit 10, and a fixing unit 30. Each part is demonstrated below.

LED used in the present invention is not particularly limited in its form. For example, the LED light emitting part is not only long as shown in FIG. 2 but also the case where the LED light emitting part is short as shown in FIG. 3. Here, when the LED emitting portion is short as shown in FIG. 3, the brightness of the LED side surface may be further emphasized as compared with FIG. 2. Furthermore, when the LED light emitting part is short as shown in FIG. 3, the shape of the light transmitting part may be modified according to the shape of the LED light emitting part. In addition, although the light emitting portion is short, it is natural that a wide LED and a round LED may also be applied to the present invention.

At least one LED is used in the present invention. There is no particular limitation on the number of LEDs here. When a plurality of LEDs are installed, LEDs of different colors may be installed, or may be installed with different angles at which individual LEDs are installed. This is to improve visibility at various angles in consideration of the linearity of light emitted from the LED.

The light transmitting part 10 surrounds the light emitting part of the LED 1, transmits the light of the LED 1 to the outside, and has a flat bottom surface. The light-emitting unit 10 prevents light from being scattered and increases the concentration of light by designating the irradiation range as the size of the shape, and various expressions can be made according to the shape of the shape. To be expressed. In addition, since the light-transmitting portion 10 surrounds the light emitting portion of the LED 1, it serves to protect the LED 1 from the external impact applied to the LED (1). The light emitted from the LED 1 is emitted to the outside through the light-transmitting portion 10, the light is reflected, diffraction, etc. while passing through the light-transmitting portion 10. The shape of the light transmitting part 10 in the present invention is not particularly limited, but in order to further improve visibility, it is preferable to include at least one thin film light emitting part 12 and at least one thick film light transmitting part 14.

The thin-film light-emitting part 12 is a thin portion of the light-transmitting part in order to reach the light of the LED 1 to a long distance, in order to alleviate the glare phenomenon at a short distance, especially in front of the LED, the thick-film light-emitting part 14 is the LED (1) The thickness of the light transmitting part is thicker than the thin film light emitting part 12 in order to emphasize the shape by easily dispersing the light of the LED and also easily recognize the light of the LED 1 from the side of the LED 1. Since the thickness of the medium through which the LED 1 light passes is thin in the thin film transmitting part 12, the light passes almost without any loss of energy, so that even people at a relatively long distance are emitted from the thin film transmitting part 12. It becomes possible to recognize the light. However, since the thin film is also present in the thin film transmitting part 12, the glare phenomenon immediately in front of the LED is alleviated.

The thickness of the thin film light-transmitting portion 12 depends on the brightness of the LED to be installed. In the case of a typical LED, the thickness is preferably 0.1 to 10 mm. If it is less than 0.1mm, there is glare in front of it, and if it exceeds 10mm, the LED light is disturbed by the thin-film light emitting part and it is difficult to reach far.

The thin-film light-emitting part 12 allows the light to reach a long distance, while also reducing the glare in front of the LED to improve the overall visibility.

The thin film light emitting part 12 may be formed by drilling a hole in the light transmitting part 10 to make the thin film light transmitting part thinner than the surroundings, or by forming a portion of the outer surface of the light transmitting part to which light is strongly emitted to be thinner than the surroundings. .

In FIG. 2, the thin film light-emitting part 12 is shown in a flat shape when viewed from the side, but if necessary, it may have a convex shape in which light may be diffused or a concave shape in which light may be collected.

The thick-film transparent portion 14 is a portion where the thickness of the transparent portion is thicker than the thin-film transparent portion 12, and since the medium is thick, a part of the light passing through the medium is reflected inside, so that the light is spread over the entire thick-film transparent portion 14. This is dispersed and released to the outside. Therefore, the light emitted from the thick film transmitting part 14 is darker than the light emitted from the thin film transmitting part 12, but it is dispersed as a whole so that the shape can be recognized from the front as well as the side of the emitting direction of the LED 1. do.

As a result, the light emitted from the thin-film light emitting part 12 reaches far in front of the LED 1 so that people at a distance can easily recognize it, while alleviating the glare just in front of the LED, so that it is near, especially in front of it. Even without eye fatigue, the LED 1 light can be recognized, and the light emitted from the thick film transmitting part 14 emits the LED light from the side of the LED 1, so that the direction of the light of the LED 1 is progressed. In terms of, the form can be easily recognized by people, contributing to the improvement of form. Furthermore, the light from the thin film light emitting part 12 is bright, and the light from the thick film light transmitting part 14 is softly reflected, and the thin film light transmitting part 12 and the thick film light transmitting part 14 are harmonized to produce a visually excellent effect. have.

The thickness of the thick film transmitting part 14 is not particularly limited, but it is preferable that the thick film transmitting part has a thickness of 1.5 to 20 times that of the thin film transmitting part 12 in order to emit light to the side surface. If it exceeds 20 times, there is a problem that the amount of light emitted to the outside is too small.

There is no particular limitation on the positions of the thin film light emitting part 12 and the back light transmitting part 14, but when considering the straightness of the light emitted from the LED 1 to reach the distance from the thin film light emitting part 12 to a long distance. Preferably, the LED 1 is formed on the front surface in which the light is most strongly emitted, and the thick film light-emitting portion 14 is preferably installed around the thin film light-emitting portion 12.

The number of the thin film light emitting part 12 and the thick film light transmitting part 14 is not particularly limited, and may be formed as many as necessary.

There is no particular limitation on the overall shape of the light transmitting part 10. Although shown in FIG. 2 with reference to a tetrahedron, it may have various three-dimensional shapes, such as a trihedron, a pentagon, a hexahedron, a hemispherical shape, etc. as needed. 4 illustrates a light transmitting unit having a hemispherical shape as an example of various three-dimensional shapes.

In addition, there is no restriction | limiting in particular about the form at the time of seeing the thin film light transmission part 12 and the thick film light transmission part 14 from the top. In general, it is circular, but in some cases, it may have a specific shape or character, including stars, triangles, squares, animal patterns, human figures, letters, and the like. In this case, it is possible to recognize the shape of a figure or a character formed in the thin film light emitting part 12 or the thick film light transmitting part 14 from the outside.

Since the thin film light emitting part 12 means a portion where the thickness of the light transmitting part is relatively thin, the thin film light transmitting part 12 first forms the light transmitting part and then inclines the portion corresponding to the thin film light emitting part 12 in the light transmitting part. It can be implemented by. 5 is a view showing that the thin film light-transmitting portion 12 is engraved. As shown in Fig. 5 (a) to (d), the thin film light-transmitting portion 12 is a portion engraved in the light-transmitting portion, the other portion is the thick film light-transmitting portion (14).

In addition, since the thick-film light-emitting part 14 means a portion where the thickness of the light-transmitting part is relatively thick, the thick-film light-emitting part 14 forms a light-transmitting part and by embossing a portion corresponding to the thick-film light-emitting part 14 in the light-transmitting part. Can be implemented. 6 is a view showing that the thick-film light-transmitting portion 14 is embossed. As shown in Figs. 6 (a) to 6 (d), the thick film light transmitting portion 14 is an embossed portion of the light transmitting portion, and the other portion becomes the thin film light transmitting portion 12. In the case of FIG. 6, the thick-film light-emitting part 14 is positioned at the center and the thin-film light-emitting part 12 is positioned around it.

Furthermore, by appropriately combining the relief and the intaglio, it is also possible to have a plurality of the thin film light-emitting portion 12 and the thick film light-transmitting portion 14 present. 7 is an exemplary view illustrating an LED assembly in which a plurality of thin film light emitting parts 12 and a thick film light transmitting part 14 are present. As shown in Figs. 7 (a) and 7 (b), there is an embossed thick film projection portion 14 'positioned at the center and another thick membrane projection portion 14 " positioned at the edge, and there is an intaglio therebetween. The thin film light-emitting part 12 which existed exists. Therefore, when viewed from the outside, the thin film light-emitting portion 12 between the central circle 14 'and the circular circle 14' 'at the edge has the brightest effect. In this case, the thin film light emitting part 12, which is a space between the central star 14 'and the square 14 " 5 to 7 show only the flat portion of the upper portion of the light transmitting portion.

In addition, in order to emphasize the visual effect of the LED light emitting device, the thin film light emitting part 12 or the thick film light transmitting part 14 may be colored. Here, the thin film transmitting part 12 and the thick film transmitting part 14 may be painted in the same color, or may be painted in different colors. In addition, a plurality of colors may be painted on the thin film light emitting part 12 and the thick film light transmitting part 14 simultaneously. Furthermore, the color may be painted only on the outside of the thin film transparent part 12 and the thick film transparent part 14. In addition, the colors emitted from one LED can be variously expressed by making the colors of the LED and the light emitting part the same or different.

The material of the light-transmitting portion 10 is not particularly limited, but may be formed of a material which can be molded and can transmit light. As an example, glass, plastic, silicone, latex, rubber, urethane, resin, epoxy resin, polycarbonate, or polymer may be mentioned. Of these, silicone having excellent moldability and strong impact resistance is most preferred.

Furthermore, the thin film light transmitting part 12 or the thick film light transmitting part 14 may be expressed in various ways by using any one or more of transparent, semitransparent, or opaque materials.

The fixing part 30 is a part located at the bottom of the LED 1 and the light transmitting part 10 and is a part for attaching the LED assembly 100 to the signboard body 200. If necessary, the PCB substrate is located or includes the PCB substrate therein. The diameter of the fixing part 30 can be adjusted large or small as needed.

The LED assembly attached to the sign body in the present invention may further form a convex lens portion to improve visibility at long distances and short distances. 8 is a schematic view of an LED assembly in which a convex lens portion is further formed. The convex lens part 80 surrounds the LED 1, and the lower part of the convex lens part 80 is coupled to the fixing part 30, and from the lower part of the fixing part 30 to the side of the LED 1. Forming a thin wall to the top, the convex lens is formed in the upper portion of the LED (1). The light emitted from the LED 1 is more widely distributed in the primary in the convex lens unit 80 and is further more widely distributed in the secondary by the light transmitting unit 10 located outside the convex lens unit 80. The convex lens may have both convex surfaces, unlike in FIG. 8.

The LED assembly according to the present invention may further attach a polycarbonate layer on top of the light transmitting portion to improve visibility. Polycarbonate emits light with a very stable feeling because of its high light diffusion and high visible light transmittance. The light diffused primarily through the light-transmitting part is diffused into the light while passing through the polycarbonate to a light having a stable feeling, thereby improving overall visibility. 9 is a cross-sectional view of an LED assembly with a polycarbonate layer attached. As shown in FIG. 9, a polycarbonate layer 84 is attached to the light transmitting part 10. There is no particular limitation on the shape of the polycarbonate layer 84 attached thereto, but in order to diffuse light, the upper portion preferably has a convex lens shape. The polycarbonate layer 84 is not particularly limited to the method of attaching to the light transmitting portion, but may be simply installed by inserting the polycarbonate layer 84 into the groove formed by engraving the upper portion of the light transmitting portion.

In order to diffuse the LED light emitted from the LED assembly in the present invention, a diffusion layer may be further attached to the lower portion of the light emitting portion facing the upper portion of the LED. 10 is a cross-sectional view of the LED assembly with the diffusion layer attached. The diffusion layer 86 is made of a material capable of diffusing light as much as possible. In particular, the diffusion layer 86 is preferably made of crystal to cause diffuse reflection. The light diffused primarily by the diffuse reflection by the diffusion layer 86 is further diffused while passing through the light-transmitting portion 10, thereby widening the range of light emitted by one LED assembly as a whole. The diffusion layer 86 is not particularly limited to the method of attaching to the light transmitting portion 10, but may be simply installed by inserting the diffusion layer 86 into a groove formed in the light transmitting portion.

Regarding the method of attaching the signboard body 200 of the LED assembly 100, the entire LED assembly 100 is integrally formed and attached to the signboard body 200, or the light transmitting unit 10 and the LED 1 are mutually connected. It may be made to be separated and fitted to the signboard body 200. In the case where the whole is made in one piece, the LED assembly 100 may be attached to the signboard body 200 in various ways. There is no particular limitation on the attachment method here, but considering the convenience of the work process, the high frequency attachment method is most preferred. 11 is a view showing that the LED assembly is attached by a high frequency attachment method. It shows that the LED assembly 100 is attached to the sign body (200).

Another attachment method is to make a plurality of fitting holes 220 at regular intervals on the signboard body 200 and to insert the LED assembly 100 into the fitting holes 220. This makes it convenient to assemble the LED assembly 100 to the signboard body 200 in the process of installing the signboard in the field, and it is also convenient to replace the damaged or problematic LED. To this end, the LED assembly 100 should have a concave shape at the bottom of the light transmitting portion. 12 illustrates another embodiment of an LED assembly. As shown in FIG. 12, in the LED assembly 100, there is a recess 40 in the lower portion of the light transmitting portion 10, and the signboard body 200 is coupled to the side of the portion. The LED assembly 100 is made of a soft material is fitted to the fitting hole 220 formed in the sign body.

On the other hand, when the light emitting unit 10 and the LED (1) is separated, as shown in Figure 13, the insertion hole 220 is put out to the signboard body, and the light emitting unit 10 is placed on the upper portion of the fitting hole 220, The lower part of the fitting hole 220 is pushed in the form of fitting the LED (1) from the bottom to the upper part to combine with the light-transmitting part (10). In this case, the LED 1 and the light projecting portion 10 are brought into close contact and fixed. Of course, on the contrary, the LED 1 may be first inserted into the lower portion of the fitting hole 220, and the light transmitting part 10 may be coupled to the upper portion thereof.

In this case, in order to strengthen the strength of the coupling, the support 50 may be further provided below the LED 1. The support 50 is in close contact with the light transmitting part 10 to completely fix the LED 1 in the light transmitting part 10, and is a part for preventing damage due to shaking of the LED 1. 14 is a cross-sectional view of the LED assembly in which the support is further installed. As shown in Figure 14, the support 50 is in close contact with the side of the light transmitting portion 10.

15 is a schematic view of an LED assembly with additional protective walls installed. As shown in FIG. 15, the diameter of the support 50 is larger than the diameter of the LED 1, and the support 50 is provided with a protective wall 52 for protecting the LED 1 around the LED 1. Can be. The protective wall 52 is formed in a circular shape around the LED 1 to prevent the LED 1 from being easily damaged by an external shock when the LED assembly used in the present invention is collapsed by a wind lamp. The protective wall 52 does not necessarily need to wrap all around the LED 1 here.

In addition, the air of the portion (C) in which the LED (1) of the light emitting portion 10 is fitted in the process of the LED (1) is fitted to the light emitting portion 10 is compressed as the LED (1) is inserted into the LED when used for a long time ( 1) is pushed by the compressed air, there is a problem that the LED (1) portion and the light transmitting portion 10 is separated. In the present invention, in order to solve this problem, it is possible to form an air discharge means in the light transmitting portion (10).

The air discharge means in the present invention includes an air discharge groove 18 or embossing (19). FIG. 16 is a cross-sectional view of the LED assembly in which two air discharge grooves are formed, and FIG. 17 is a cross-sectional view taken along the line AA of FIG. 16. As shown in FIG. 16 and FIG. 17, at least one groove is formed in the insertion direction of the LED 1 at a portion in contact with the LED 1 in the light transmitting part 10. The air discharge groove 18 serves to discharge the air inside the floodlight 10 to the outside in the process of fitting the LED (1).

18 is a sectional view of an LED assembly with embossing formed. In addition, as shown in FIG. 18, at least one embossing is formed at a portion in contact with the LED 1 inside the light transmitting part 10. In the process of fitting the LED 1, the air inside the light transmitting portion 10 is discharged to the outside through the space between the embossing (19) to prevent the formation of excessive compressed air inside the light transmitting portion.
