Description

LED advertising sign with improved visibility {advanced visibility of ad sign}

The present invention relates to a signboard, and in detail, by attaching an LED assembly to a conventional signboard, visibility is improved, but the LED assembly covers a light transmitting part having a thin-film light-transmitting part and a thick-film light-transmitting part on the LED to prevent light from spreading and The irradiation range is designated by the size of the light-transmitting part, and the thin-film light-transmitting part allows light to reach far, alleviating the glare in front of the LED, and the thick-film light-transmitting part has a thick medium, so a part of the light passing through the medium is prevented from inside. The present invention relates to a signboard with improved visibility by maximizing the advertising effect by improving the visibility of signboards at a distance/near distance and front/side by allowing light to be transmitted to the side by being reflected.

Signboards are signs that a store, company, office, or institution writes their name, sales product, business category, etc., and hangs or attaches them so that they are conspicuous to people, and has existed since ancient times in both the East and the West.

Depending on the place of installation, signs include rooftop signs, wall signs, protruding signs, storefront signs, standing signs, and billboards (signs placed on fields, mountains, and highways). Signs can also be found in the field of traffic advertisements, and include in-vehicle advertisements, out-of-vehicle advertisements, and fixed advertisements (inside and outside the station premises).

In the modern world, as commercial activities become more complex and diversified, and competition in the same industry intensifies, various types of signboards are appearing countless times. Therefore, the signboard in the modern society must be able to clearly and quickly deliver the content to be conveyed at a glance, as it stands out among countless signboards. For this purpose, various luminous bodies are attached to signboards, and among them, LEDs are widely used due to various advantages.

However, the biggest disadvantage of these LEDs is that since the LED emits front light, if you look at the LED right in front of the LED, the brightness is high and there is a glare phenomenon, which easily fatigues the eyes. Furthermore, if a character is created by combining these LEDs, it is difficult to accurately recognize the character due to glare in front of the LED.

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 signboard expressing characters or figures by combining several LEDs, eyes are easily fatigued by the glare in front of the LED and it is difficult to recognize the shape of the emitter. On the contrary, the shape of the emitter is not properly reached from the side. Since it is not easy to recognize, there are cases in which it is difficult to accurately recognize at a glance what the content is intended to convey on the signboard as a whole.

Furthermore, because of the front emission of the above-described LED and the straightness of the light emitted from the LED, a light emitting device using a conventional LED has a relatively narrow range to which one LED light is irradiated. Therefore, it is necessary to use a plurality of LEDs, but the content to be expressed. Can be displayed, and it can be recognized from a distance and a short distance. However, in this case, since a large number of LEDs have to be installed, the circuit configuration is complicated, installation cost, material cost, etc. are required, and maintenance costs are high, and there is a problem that is difficult to repair.

In addition, if the LED installed on the signboard is damaged due to the fact that an object is blown from the outside or collapsed by the wind, etc. during use, the damaged LED must be replaced.To replace it in the field, the entire LED assembly must be disassembled. There was an inconvenience of having to repair it or replace it with a new one.

Signs must be able to accurately and quickly deliver the content to be conveyed at a glance, and can be remembered for a long time in the mind of the person who saw the sign. To this end, signboards using LED luminous bodies have appeared. However, since the LED emits frontal light and the light emitted from the LED goes straight, a relatively large amount of light reaches directly in front of the LED, causing a glare phenomenon, and from the side, the light emitted from the LED hardly reaches. Signs with LEDs are sometimes 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, a large number of LEDs must be used, so installation and maintenance costs are high, and replacement is very inconvenient.

The present invention was invented to solve the above-described problem, and the present invention improves visibility by attaching an LED assembly to a conventional signboard, but the LED assembly covers the light-transmitting portion having a thin-film light-transmitting portion and a thick-film light-transmitting portion on the LED so that light is It prevents scattering and designates the irradiation range of light by the size of the light-transmitting part.The thin-film light-transmitting part allows the light to reach far and alleviates the glare right in front of the LED, and the thick-film light-transmitting part passes through the medium because the medium is thick.

Therefore, there is an effect of reducing not only the installation cost of the signboard, but also the maintenance cost.

The present invention is characterized in that a specially manufactured LED assembly is attached to a conventional sign in order to improve the visibility of a sign that can be easily seen around us.

Hereinafter, the configuration and operation of an embodiment of the present invention will be described in detail based on the exemplary drawings. However, the following examples are provided so that those skilled in the art can fully understand the present invention, and the scope of the present invention is not limited by the following examples.

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

The sign body 200 is a body part of the signboard according to the present invention, and the signboard body 200 means what is commonly referred to as a signboard on the market at present, and there is no particular limitation on this. In the sign body 200, the content to be transmitted is usually displayed, and the LED assembly 100 must be attached to a necessary part. A specific example of the sign body 20 0 will be described in more detail in the following embodiments.

The LED assembly 100 is attached to the sign body 200 at regular intervals. 2 is a cross-sectional view of an 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 part 10, and a fixing part 30. Each part will be described below.

The LED used in the present invention is not particularly limited in its shape. For example, not only the case where the LED light-emitting portion is long as shown in FIG. 2 but also the case where the LED light-emitting portion is short as shown in FIG. 3 is included. Here, when the LED light-emitting portion is short as shown in FIG. 3, the brightness of the side of the LED may be more emphasized compared to FIG. 2. Furthermore, when the LED light-emitting portion is short as shown in FIG. 3, the shape of the light-transmitting portion may be changed according to the shape of the LED light-emitting portion. In addition, although the light-emitting portion is short, it is natural that wide-shaped LEDs and round-shaped LEDs can also be applied to the present invention.

At least one LED used in the present invention is installed. There is no particular limitation on the number of LEDs here. When multiple LEDs are installed, LEDs of different colors can be installed, and further, each LED can be installed at different angles. This is to improve visibility from various angles in consideration of the straightness of the 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 transmitting unit 10 prevents light from being scattered and increases the concentration of light by designating the irradiation range in the size of the shape, and various expressions are possible according to the shape of the shape, and multiple colors, shapes, and brightness are available in one LED assembly. Let it 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 an external shock applied to the LED 1. The light emitted from the LED (1) is emitted to the outside through the light-transmitting part (10), and the light is reflected, diffracted, etc. while passing through the light-transmitting part (10). There is no particular limitation on the shape of the light-transmitting part 10 in the present invention, but it is preferable to include at least one thin-film light-transmitting part 12 and at least one thick-film light-transmitting part 14 in order to further improve visibility.

The thin-film light-transmitting part 12 is a thin part of the light-transmitting part in order to reach the light of the LED 1 to a long distance, but to alleviate the glare phenomenon at a short distance, especially in front of the LED, and the thick-film light-transmitting part 14 is the LED(1). ), the light of the light-transmitting part is thicker than that of the thin-film light-transmitting part 12 in order to easily recognize the light of the LED 1 from the side of the LED 1 and emphasize the shape. In the thin film transmitting part 12, since the thickness of the medium through which the LED(1) light passes is thin, the light passes almost without loss of energy, and therefore, even people in a relatively distant distance are emitted from the thin-film transmitting part 12 You will be able to recognize the light that is becoming. However, since a thin film is also present in the thin film light transmitting part 12, the glare phenomenon immediately in front of the LED is alleviated.

The thickness of the thin film light-transmitting portion 12 varies depending 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 a glare in front of it, and if it exceeds 10mm, the LED light is disturbed by the thin film transmitting part, making it difficult to reach far.

The thin film transmitting part 12 improves overall visibility by mitigating the glare phenomenon right in front of the LED while allowing light to reach a long distance.

The thin-film light-transmitting part 12 may be formed by making a hole in the light-transmitting part 10 so as to make the thin-film light-transmitting part thinner than the periphery, or forming a portion of the outer surface of the light-transmitting part to be lightly emitted to be thinner than the surroundings. .

2 shows a flat shape when viewed from the side of the thin film light transmitting part 12, but may have a convex shape in which light can be diffused or a concave shape in which light can be collected, if necessary.

The thick-transmitting portion 14 is a portion whose thickness of the light-transmitting portion is thicker than that of the thin-film-transmitting portion 12, and because the medium is thick, some of the light passing through the medium is reflected from the inside and Is dispersed and released to the outside. Therefore, the light emitted from the thick-film transmitting unit 14 is dark compared to the light emitted from the thin-film transmitting unit 12, but is distributed throughout, so that the shape can be recognized not only from the front side but also from the side of the light emitting direction of the LED(1). You will be able to.

As a result, the light emitted from the thin-film emitter 12 reaches far in front of the LED (1) and can be easily recognized by people at a distance, while reducing the glare in front of the LED in a short distance, especially in front of the LED. Also, the LED(1) light can be recognized without eye fatigue, and the light emitted from the thick-film emitter 14 is also emitted from the side of the LED(1), so the direction of the light of the LED(1) Also in the aspect of morphology, it contributes to the improvement of morphology by making it easier for people to recognize the shape. Furthermore, the light from the thin-film transmitting part 12 is bright, and the light from the thick-transmitting part 14 is subtly shining so that the thin-film transmitting part 12 and the thick-film transmitting part 14 harmonize to show a very excellent effect visually. have.

Although there is no particular limitation on the thickness of the thick-transmitting portion 14, it is preferable that the thick-transmitting portion has a thickness of 1.5 to 20 times that of the thin-film-transmitting portion 12 in order to emit light to the side. If it exceeds 20 times, there is a problem that the amount of light emitted to the outside becomes too small.

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

In addition, there is no particular limitation on the number of the thin-film transmissive portions 12 and the thick-film transmissive portions 14, and several may be formed if necessary.

There is no particular limitation on the overall shape of the light transmitting part 10. Although shown in FIG. 2 based on a tetrahedron, it may have various three-dimensional shapes such as a trihedron, a pentahedron, a hexahedron, and a hemispherical shape, if necessary. 4 illustrates a light transmitting part having a hemispherical shape as an example of various three-dimensional shapes.

In addition, there is no particular limitation on the shape of the thin film transmitting portion 12 and the thick layer transmitting portion 14 when viewed from above. In general, it has a circular shape, but in some cases, it may have a specific shape or a character shape including a star, a triangle, a square, an animal pattern, a human shape, a letter shape, and so on. In this case, the shape of a figure or character formed on the thin-film light-transmitting portion 12 or the thick-film light-transmitting portion 14 can be recognized from the outside.

Since the thin-film transmissive part 12 refers to a portion in which the thickness of the transmissive part is relatively thin, the thin-film transmissive part 12 forms a translucent part first, and then, in the translucent part, a portion corresponding to the thin-film transmissive part 12 is inscribed. Can be implemented by 5 is a view showing that the thin film transmissive portion 12 is engraved. As shown in Figs. 5A to 5D, the thin-film light-transmitting portion 12 is an intaglio portion of the light-transmitting portion, and the other portion becomes the thick-film light-transmitting portion 14.

In addition, since the thick-transmitting portion 14 refers to a portion where the thickness of the light-transmitting portion is relatively thick, the thick-transmitting portion 14 forms a light-transmitting portion and embosses the portion corresponding to the thick-transmitting portion 14 from the light-transmitting portion. Can be implemented by 6 is a view showing that the thick film transmitting part 14 is embossed. As shown in FIGS. 6A to 6D, the thick-film transmissive portion 14 is an embossed portion of the translucent portion, and the other portions become the thin-film transmissive portion 12. In the case of FIG. 6, it is a view showing that the thick film transmitting part 14 is located in the center and the thin film transmitting part 12 is located around it.

Furthermore, by appropriately combining the embossed and the engraved, it is possible to make a plurality of thin film transmissive portions 12 and thick transmissive portions 14 exist. 7 is an exemplary view of an LED assembly in which a plurality of thin-film light-transmitting parts 12 and thick-film light-transmitting parts 14 are present. As shown in Figs. 7(a) and 7(b), there is an embossed thick film transmitting part 14' located in the center and another thick film transmitting part 14'' located at the edge, and an intaglio between them. The thin-film translucent portion 12 is present. Therefore, when viewed from the outside, in the case of Fig. 7(a), the thin film transmitting part 12 between the circle 14' at the center and the circle 14'' at the edge looks brightest, and Fig. 7(b) In the case of, the thin film transmitting part 12, which is the space between the star 14 ′ in the center and the square 14 ″ at the edge, looks brightest. 5 to 7 show only a flat portion of the upper portion of the light transmitting part.

In addition, in order to emphasize the visual effect of the LED light-emitting device, the thin film light-transmitting portion 12 or the thick-film light-transmitting portion 14 may be painted with a color. Here, the thin film transmitting part 12 and the thick film transmitting part 14 may be painted in the same color, but may be painted in different colors. In addition, several colors may be simultaneously painted on the thin film transmitting part 12 and the thick film transmitting part 14. Further, only the outside of the thin film transmitting part 12 and the thick film transmitting part 14 may be colored. In addition, the light emitted from one LED can be expressed in various ways by making the color of the LED and the light transmitting part the same or different from each other.

There is no particular limitation on the material of the light-transmitting portion 10, but any material that can be molded and transmits light may be used. Examples include glass, plastic, silicone, latex, rubber, urethane, resin, epoxy resin, polycarbonate, or polymer. Among these, silicone is most preferable, which is excellent in moldability and is resistant to impact.

Furthermore, the thin film transmitting part 12 or the thick film transmitting part 14 can be expressed in various ways by a combination of any one or more of transparent, translucent, or opaque materials.

The fixing part 30 is a part located on the bottom of the LED 1 and the light transmitting part 10, and is a part for attaching the LED assembly 100 to the sign body 200. If necessary, the PCB board is located in this part or the PCB board is included inside. The diameter of the fixing part 30 can be adjusted as large or small as necessary.

The LED assembly attached to the signboard body in the present invention may additionally form a convex lens portion to improve visibility at a distance and a short distance. 8 is a schematic diagram of an LED assembly in which a convex lens portion is additionally formed. The convex lens unit 80 is in the form of enclosing the LED 1, and the lower portion of the convex lens unit 80 is coupled to the fixing unit 30, and from the lower portion of the fixing unit 30 to the side of the LED 1 It forms a thin wall and rises to the top, and a convex lens is formed on the top of the LED (1). The light radiated from the LED 1 is firstly dispersed more widely in the convex lens unit 80, and then secondly more widely distributed by the light transmitting unit 10 located outside the convex lens unit 80. Unlike FIG. 8, the convex lens may have both surfaces convex.

In the LED assembly of the present invention, a polycarbonate layer may be additionally attached to the top of the light transmitting part in order to improve visibility. Polycarbonate emits light with a very stable feeling due to its high light diffusion and high transmittance of visible light. The light that is primarily diffused while passing through the light-transmitting part is diffused secondarily while passing through the polycarbonate, and changes into light with a stable feeling, thereby improving overall visibility. 9 is a cross-sectional view of an LED assembly to which a polycarbonate layer is attached. As shown in FIG. 9, a polycarbonate layer 84 is attached to the top of the light transmitting part 10. There is no particular limitation on the shape of the polycarbonate layer 84 attached here, but it is preferable that the upper portion has the shape of a convex lens in order to diffuse light. There is no particular limitation on the method of attaching the polycarbonate layer 84 to the light-transmitting part, but it may be simply installed by inserting the polycarbonate layer 84 into a groove formed by engraving the upper part of the light-transmitting part.

In order to widely diffuse the LED light emitted from the LED assembly in the present invention, a diffusion layer may be additionally attached to the lower part of the light transmitting part facing the upper part of the LED. 10 is a cross-sectional view of an LED assembly to which a diffusion layer is attached. The diffusion layer 8 6 is made of a material capable of diffusing light as much as possible, and in particular, it is preferably made of a crystal in order to induce diffuse reflection. The light firstly diffused by the diffuse reflection by the diffusion layer 86 is further diffused while passing through the light transmitting part 10, so that a range that is illuminated by one LED assembly as a whole is widened. There is no particular limitation on the method of attaching the diffusion layer 86 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 sign body 200 of the LED assembly 100, the entire LED assembly 100 is made integrally and attached to the sign body 200, or the light transmitting part 10 and the LED 1 It may be made to be separated so that it may be fitted to the sign body 200. When the whole is made integrally, the LED assembly 100 may be attached to the sign body 200 in various ways. There is no particular limitation on the attachment method here, but the high-frequency attachment method is the most preferable considering the convenience of the work process. 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 put out a plurality of fitting holes 220 at regular intervals on the sign body 200 and insert the LED assembly 100 into the fitting holes 220. As a result, it is convenient to assemble the LED assembly 100 to the sign body 200 in the process of installing the signboard in the field, and further, it is convenient to replace the damaged or problematic LED. To this end, the LED assembly 100 must have a concave lower portion of the light-transmitting portion. 12 is a view showing another embodiment of the LED assembly. As shown in FIG. 12, in the LED assembly 100, there is a concave portion 40 at the lower portion of the light-transmitting portion 10, so that the sign body 200 is coupled to the side of this portion. This LED assembly 100 is made of a soft material and is fitted into the fitting hole 220 formed in the sign body.

On the other hand, when the light transmitting part 10 and the LED 1 are separated, as shown in FIG. 13, a fitting hole 220 is provided in the sign body, and the light transmitting part 10 is placed on the upper part of the fitting hole 220, The LED(1) part is pushed in the form of inserting the LED(1) part from the bottom to the top in the lower part of the fitting hole 220 to be combined with the light-transmitting part 10. In this case, the LED 1 and the light transmitting part 10 come into close contact and are fixed. Of course, on the contrary, the LED 1 may be first inserted into the lower part of the fitting hole 220 and then the light transmitting part 10 may be coupled to the upper part.

In order to increase the strength of the bonding in this case, a support 50 may be additionally installed under the LED 1. The support 50 is completely 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 the shaking of the LED 1. 14 is a cross-sectional view of an LED assembly in which a support is additionally installed. As shown in FIG. 14, the support 50 is completely in close contact with the side of the light transmitting part 10.

15 is a schematic diagram of an LED assembly in which a protective wall is additionally installed. As shown in FIG. 15, the diameter of the support 50 is larger than the diameter of the LED 1, and a protective wall 52 for protecting the LED 1 around the LED 1 is installed on the support 50. You can.

In the conventional channel signage, the bottom of the channel part where the light-emitting body is installed and the cover part must be separated by a certain distance (H) or more in order to allow the light of the luminous body installed inside the channel part to be spread throughout the cover part. Must have. If the distance between the luminous body and the cover part is short, there are strong and weak parts in the cover part.

However, in the present invention, since the light reaches the cover part 240 after the light is first diffused by the light-transmitting part 10 in the LED assembly, which is a light-emitting body, the height H may be relatively small compared to the conventional channel board. Also, according to the diffusion of light from the light transmitting part, even if fewer LED assemblies are installed than before, the same effect as the previous channel signboard can be obtained.

In general, the installation cost of the channel signage consists of 50% of the installation cost of the channel part and 50% of the installation cost of the luminous body.The channel signage according to the present invention has a lower height (H) of the channel part, thereby reducing the cost of raw materials and further reducing the number of luminous bodies. There is a 50% reduction in installation cost.

In addition, since the number of LEDs is lower than that of the previous signboard, the maintenance cost of the signboard is reduced, so the power consumption is also reduced, and thus the maintenance cost is also lower than that of the previous channel signboard.
