Description

Wireless LED module using conductive plate, manufacturing method thereof and advertising board attached thereto {Wireless rens using conductive plate, it's manufacturing method and sign using it}

The present invention relates to a wireless LED module using a conductive plate and a billboard attached thereto, and in detail, by using a conductive plate attached to both sides of an insulating layer instead of a wire for supplying power to a conventional LED. The present invention relates to a wireless LED module using a new concept of a conductive plate that dramatically improves the risk of electric accidents, contact failures and appearance problems due to complicated wires, a manufacturing method thereof, and a billboard attached thereto.

In the past, signboards and banners have been installed with lighting facilities to improve visibility at night to maximize the advertising effect. In recent years, a signboard or banner that has taken a step further and has maximized visibility by attaching a lens-covered LED to the letters or figures of the signboard or banner has appeared.

1 is an example of a banner attached to the LED with a lens, it is a view showing the back of the banner in the state that the LED is attached to the lens attached to the letter 'ga'. To make a banner as shown in Figure 1, after printing the letter 'ga' on a cloth or film to be used as a banner, the LED was attached to the letter using a high-frequency compression method. Next, the LEDs were connected to an external power supply, and the individual LEDs were also connected to each other by wires. However, in this process, it takes a considerable time to connect the individual LED to the wire, there was a problem that productivity is reduced. In addition, in the case of using a product in the form of the LED and the wire connected in order to shorten the connection time, if the wire between the LED and the LED is long, as shown in Figure 1a, the wire sag down, as shown in b of Figure 1 If the wires between the LEDs are short, the connection line must be used in the middle, so that the back of the signboard or banner using the LED is very complicated with the wires. As a result, the back of the sign or banner was thickened with numerous wires, so that even if the back of the sign or banner was finished, the sign or banner had to have a considerable thickness to accommodate the wire inside. In addition, there is a high risk of an electrical accident due to a complicated wire, and even if a problem caused by a poor connection between the LED and the wire, there was a problem that it is difficult to determine where the problem occurred.

In addition, if the anode and cathode of the LED is connected to the wire, there is a high possibility of connection failure at the contact point, and if the connection failure occurs, the LED does not function properly, and thus the signboard or banner on which the LED is installed has no problem. .

Furthermore, in the related art, a high frequency compression method is mainly applied to a signboard or a banner, or a groove is formed in a signboard or a banner to insert a lensed LED therein. In this case, if a problem occurs in the LED, the lensed LED is separated. After removing and repairing or replacing the problem LED, the lens-covered LED needs to be attached to the banner or signboard, which is very inconvenient and time-consuming.

As shown in Figure 2, the wireless LED module using a conductive plate according to the present invention includes a conductive plate 100 and at least one LED assembly 200 coupled thereto. Each part is demonstrated below.

3 is a cross-sectional view of the conductive plate. As shown in FIG. 3, the conductive plate 100 includes three layers. That is, the lower conductive layer 120, the insulating layer 110, and the upper conductive layer 130 are formed. The lower conductive layer 120 and the upper conductive layer 130 are made of a conductive material such as copper, aluminum, iron, and silver. The insulating layer 110 is a layer positioned between the upper conductive layer 130 and the lower conductive layer 120 and is made of an insulating material such as paper, wood, glass, rubber, synthetic resin, and polymer compound. Examples of the insulating layer include those made of polypropylene or polyethylene.

In addition, the conductive plate may be made of a material that can be bent, but may also be made of a material that cannot be bent into a hard board.

The upper conductive layer 130 and the lower conductive layer 120 are connected to the anode and the cathode of the power supply (not shown), respectively, so that the upper conductive layer 130 and the lower conductive layer 120 serve as the anode and the cathode, respectively. do. Here, the upper conductive layer 130 and the lower conductive layer 120 need only be connected to either one of the anode and the cathode, respectively, so that the upper conductive layer 130 does not necessarily need to be connected to the anode. The insulating layer 110 is a portion for maintaining insulation between the upper conductive layer 130 and the lower conductive layer 120 serving as an anode and a cathode. In addition, since the bonding of the upper conductive layer 130, the insulating layer 110 and the lower conductive layer 120 may be made by a known method, a detailed description thereof will be omitted.

That is, although the length of the wire between the base is fixed in the prior art, the product according to the present invention has the advantage that it can be made freely to attach the LED assembly at a desired interval.

Figure 4 is a cross-sectional view of the LED assembly coupled to the conductive plate according to the first embodiment of the wireless LED module using a conductive plate according to the present invention. The first embodiment of the LED assembly 200 in the present invention includes a base 210, the LED unit 220 and the lens 240.

The base 210 is coupled to the coupler 150 formed in the conductive plate 100, and includes a base 211 and a side wall 213. 5 is a plan view of the base. As shown in FIGS. 4 and 5, the edge portion 212 is formed in the support portion 211 larger than the diameter of the coupling hole 150, so that the LED assembly 200 falls out to the front surface of the conductive plate 100. prevent. The side wall 213 is a portion protruding upward through the coupling hole 150 in the supporting portion 211, and two side wall grooves 214 are formed in the side wall 213. The side wall 213 generally has a cylindrical shape, and an inner space in which the LED unit 220 is accommodated is formed in the side wall 213.

6 is a plan view of the LED unit. The LED unit 220 includes an LED 221 and an LED substrate 222, which are located in an internal space. LED 221 used in the present invention is not particularly limited in its form. For example, the case where the LED light emitting part is long is included, as well as the case where the LED light emitting part is short. 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 221 used in the present invention is installed. Here, the number of LEDs 221 is not particularly limited. When a plurality of LEDs 221 are installed, different colors of LEDs 221 may be installed, and may be installed by varying the angle at which the individual LEDs 221 are installed. This is to improve visibility at various angles in consideration of the linearity of light emitted from the LED 221.

The LED substrate 222 is located under the LED 221, and two wing plates 223 and 224 connected to the anode and the cathode of the LED 221 are attached to the LED substrate 222, respectively. The two wing plates 223 and 224 pass through the sidewall grooves 214 of the base 210 described above. One of the two wing plates 223, 224 is connected to the anode of the LED 221, and the other is connected to the cathode of the LED 221. Here, one wing plate 224 of the two wing plates is positioned under the lower conductive layer 120, and the other wing plate 223 is positioned above the upper conductive layer 130.

To this end, the wing plate 223 positioned on the upper conductive layer 130 is connected to the LED substrate 222 on the upper portion of the LED substrate 222, and the wing plate positioned on the lower portion of the lower conductive layer 120 ( 224 is connected to the LED substrate 222 at the bottom of the LED substrate 222.

Therefore, the power applied from the power supply unit is supplied to the LED 221 through the upper conductive layer 130 and the lower conductive layer 120 and two wing plates 223 and 224. In the present invention, the wing plate includes a circular conductor as well as a plate-shaped conductor, which means that the wing plate electrically connects the conductive plate 100 and the LED substrate 222 regardless of its shape. do. Therefore, the sheath of the electric wire can be peeled off and cut to a suitable length to be used as a wing plate.

The lens 240 is coupled to the outside of the side wall 213. The lens 240 surrounds the light emitting part of the LED 221 and transmits the light of the LED 221 to the outside, and has a flat bottom surface. The lens 240 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 are possible according to the shape of the shape. To be possible. In addition, since the lens 240 surrounds the light emitting part of the LED 221, the lens 240 serves to protect the LED 221 from an external impact applied to the LED 221. The light emitted from the LED 221 is emitted to the outside through the lens 240, the light is reflected, diffraction, etc. while passing through the lens 240. There is no particular limitation on the lens 240 used in the present invention, but the lens 240 in the present invention may be composed of at least one thin film light emitting part and at least one thick film light transmitting part.

7 is a cross-sectional view of a lens in which a thin film light transmitting part and a thick film light transmitting part are formed. As shown in FIG. 7, the lens according to the present invention includes a thin film light emitting part and a thick film light transmitting part. The thin-film light-emitting part 241 is a thin portion of the light-transmitting part in order to reach the light of the LED 221 to a long distance, in particular to alleviate the glare phenomenon in the short distance, especially in front of the LED, the thick-film light-emitting part 242 is the LED (221) The thickness of the light transmitting part is thicker than the thin film light transmitting part 241 in order to emphasize the shape by easily dispersing the light of the LED 221 to easily recognize the light of the LED 221 from the side of the LED 221. Since the thickness of the medium through which the light of the LED 221 passes is thin in the thin film light emitting part 241, the light passes almost without any energy loss, and thus, even people at a relatively long distance are emitted from the thin film light transmitting part 241. It becomes possible to recognize the light. However, since the thin film is also present in the thin film transmitting part 241, the glare phenomenon immediately in front of the LED is alleviated.

The thickness of the thin film light-transmitting portion 241 depends on the brightness of the LED to be installed. In the case of a conventional 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-transmitting unit 241 allows the light to reach a long distance, and also reduces the glare in front of the LED, thereby improving the overall visibility.

The thick-film transparent portion 242 is a portion where the thickness of the transparent portion is thicker than the thin-film transparent portion 241. Since the medium is thick, a part of the light passing through the medium is reflected from the inside, and the light is transmitted over the entire thick-film transparent portion 242. This is dispersed and released to the outside. Therefore, the light emitted from the thick film transmitting part 242 is darker than the light emitted from the thin film transmitting part 241, but is dispersed as a whole so that the shape can be recognized from the front as well as the side of the light emitting direction of the LED 221. do.

As a result, the light emitted from the thin-film light emitting part 241 reaches far in front of the LED 221, so that people at a great distance can easily recognize it, while alleviating the glare immediately in front of the LED, so that the light is near, especially in front of the LED. Even without eye fatigue, the LED 221 light can be recognized, and the light emitted from the thick film transmitting part 242 is emitted from the side of the LED 221 so that the LED light is emitted. 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 241 is bright, and the light from the thick film light transmitting part 242 is lightly reflected, so that the thin film light transmitting part 241 and the thick film light transmitting part 242 harmonize to have a visually excellent effect. have.

The thickness of the thick film transmitting part 242 is not particularly limited, but the thick film transmitting part may have a thickness of 1.5 to 20 times that of the thin film transmitting part 241 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 overall shape of the lens 240. If necessary, it may have various three-dimensional shapes, such as a tetrahedron, tetrahedron, pentahedron, hexahedron, hemisphere, and the like. In some cases, it may have a specific shape or character, including stars, triangles, squares, animal patterns, human shapes, letters, and the like. In addition, all or part of the lens 240 may be colored.

The material of the lens 240 is not particularly limited, but may be formed of a material that 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. Among them, silicone having excellent moldability and polycarbonate having excellent light expandability are most preferred.
