Description

SIGNBOARD LED LAMP WITH PCB COMBINATION STRUCTURE}

The present invention relates to a coupling structure between a lighting and a printed circuit board applied to a lighting device for a signboard, and in particular, a power supply is smoothly supplied to an LED lamp mounted on a printed circuit board. It relates to a coupling structure between the LED lamp for the signboard and the printed circuit board to provide a structure to facilitate the coupling between the housing and the printed circuit board accommodated.

There are various kinds of signboards, but typically, a simple signboard with an ad text on the surface, a signboard with a fluorescent lamp inside the ad text on the surface, and a lamp in a channel form of ad text Channel-type signboard with built-in, and neon sign itself made by bending the neon lamp itself in the form of advertising.

The former two billboards are widely used because they are relatively inexpensive to manufacture and simple to operate, but they do not attract much attention and have a poor appearance, so there are many neon signs to create a different atmosphere. It is used.

However, in the case of neon signs, the neon lamp should be bent by applying heat by hand to bend the neon lamp and infusing air so that the bend does not shrink. It is difficult to form ad text. In addition, in the case of neon signs, there is a risk of electric shock accidents, etc., due to the use of a high voltage of 12,000V, has a drawback of a large amount of electricity consumption, short life. In addition, since the neon lamp is made of glass, there is a high possibility that the neon lamp will be broken during manufacture, handling, transportation, and the like. Neon lamps also contain mercury, which is not good for the environment.

In consideration of the problems of the neon signboard, LED billboards using LEDs (LEDs) are proposed.

LED advertising signage is safe by using low voltage of 5 ~ 9V, and it can reduce electricity consumption by 60% compared to neon signboard, and it has the advantage of long life and easy handling because it is not damaged easily.

There are various kinds of LED billboards. For example, Korean Patent Laid-Open Publication No. 2004-49697 discloses an LED billboard having an electronic signboard structure in which LEDs are arranged in a lattice shape to emit various advertisement texts. By the way, in the case of such an LED sign, it is suitable for text advertising, but the character itself is schematic, the aesthetics are inferior, there is a problem that it is difficult to express various designs.

In addition, Korean Patent No. 540592 discloses an LED signboard in which a plurality of LEDs are arranged along the design form in a channel of an advertising design form. However, in the case of this signboard, it cannot be applied to a signboard without a case or channel.

Korean Patent No. 540592 discloses an LED signboard in which a plurality of LEDs are arranged in a channel in the form of an advertising design, but is not applicable to a signboard without a case or channel. In addition, the Korean Registered Utility Model No. 347653 discloses an LED module, which provides a structure in which the LED module is placed along the advertisement text to create an advertisement text.

However, the LED module is achieved by combining the lower frame and the upper frame.

Since the LEDs are arranged along the length in front of the horizontal case, the LED module cannot be bent along the ad text. For example, to make an L shape, the LED module is cut into two pieces corresponding to the horizontal part and the vertical part. Since it is necessary to connect the wires by placing the, making the signboard is very cumbersome.

In particular, as described above, there is a problem that it is very difficult to make a billboard with a large number of advertising texts or a curved portion.

Recently, the technical contents having a similar configuration, such as Korean Patent No. 550400 or Korean Patent No. 2010-18843, have been disclosed to be connected by a power cable using a block unit in which a plurality of LEDs are formed. .

In the case of interconnecting the blocked units with a power cable, wires typically pass through the bottom of the case, and a small screw or the like is mounted on the upper side of the case by mounting a printed circuit board on which an LED lamp is mounted. After passing through the printed circuit board so that the covering of the wire is forcibly peeled off by the screw, a series of processes of molding with epoxy on the surface of the printed circuit board is performed.

However, as described above, when a small screw or the like penetrates the printed circuit board and the electric wire is peeled off so that the electric wire is energized, the electric wire is not completely contacted with the electric stripped wire and the screw according to the skill of the operator. The short-circuit supply has been a factor in increasing the defective rate.

The present invention has been made in view of the above-described problems, and includes a connecting pin penetrating between an incomplete energized form of a screw and penetrating between the printed circuit board and the case, and covering of the wire on the end position side of the connecting pin. It is an object of the present invention to provide a coupling structure between an LED lamp for a signboard and a printed circuit board to enable smooth energization without a short circuit of a power supply.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is to apply to the advertising signboard using a printed circuit board 10 forming a module (1) in which the LED lamp (2) is surface-mounted, a plurality of LED lamp (2) as shown in FIG. It consists of a printed circuit board 10 having a case, the case 30 on which the printed circuit board 10 is seated, the case 30 is made up of a plurality of penetrating through the bottom of each case 30 to supply power It is connected by wires 50 for feeding.

Surface treatment of the printed circuit board 10 and the type and operation of the circuit pattern may be carried out according to the conventional technical level.

Through the printed circuit board 10 is grounded with the wire 50 passing through the case 30 to be described later in the longitudinal direction and supplies power to the circuit pattern side of the printed circuit board 10 and the LED lamp (2) In order to turn on, the connection pin 20 penetrating the printed circuit board 10 is configured.

In order to insert and fix the connection pin 20, the hole 11 is drilled to a suitable portion of the printed circuit board 10, that is, a position capable of supplying power to a circuit pattern, and solder masked around the hole 11. After pressing the connecting pin 20 to the hole (11) side by force to form, and then performing a surface mount treatment operation called a conventional SMD operation, as shown in Figure 2 LED lamp 2 is provided The modular printed circuit board 10 can be obtained.

It is provided with a case 30 for mounting such a printed circuit board 10 is blocked, the case 30 is formed in a rectangular shape having a shape that is opened up and down as shown in Figure 2 and up and down inside It has a partition plate 33 for partitioning.

The lower side of the case 30 is provided with a wire 50 penetrating through the case 30 and extending along the longitudinal direction, each of the inlet hole to the lower side of both sides of the case 30 for the introduction of the wire 50 (31) was formed.

Of course, the inlet hole 31 may vary depending on the number of inlets of the wire 50.

In addition, the upper side divided by the partition plate 33 of the case 30 is the epoxy molding process after the above-described printed circuit board 10 is seated, the lower side the epoxy molding in the form of passing the wire 50 Is processed to form an epoxy molding portion 40 that is all epoxy molded in the upper and lower portions of the case 30.

In addition, when the epoxy molding portion 40 to the lower side of the case 30 is completed, it is preferable to cover the lower side of the case 30 using the cover 60.

On the other hand, while the printed circuit board 10 is seated on the partition plate 33 of the case 30, the connecting pin 20 which is fixed while penetrating the printed circuit board 10 penetrates the partition plate 33. Since it should be possible, the through hole 34 should be drilled at the position of the partition plate 33 corresponding to the position of the connecting pin 20.

As such, the position where the hole 34 is drilled and the position of the connection pin 20 should be present at the same position, and the connection pin 20 is inserted along the hole 34 and the printed circuit board 10 The bottom surface side has a form that is seated on the upper surface side of the partition plate 33 of the case 10.

At this time, if the connection pin 20 is inserted through the partition plate 33 of the case 10 of the wire 50, that is, the portion of the wire 50 drawn into the case 30, the connection pin The end of 20 is in contact with the wire 50 side.

Therefore, in order to conduct electricity between the wires 50 in contact with the connection pins 20, the part surface coating of the wires 50 in contact with the connection pins 20 needs to be peeled off so that the wires are drawn into the case 30 as described above. A portion of the wire 50, that is, the portion of the wire 50 in contact with the connection pin 20, should be pulled into the case 30 inside the stripped state.

In this way, the coating stripping position of the wire 50 corresponding to the position of the connection pin 20 in the case 30 is calculated, and the coating stripping operation of the portion selected from the wire 50 is performed in advance by the coating stripping device or the like. Should be.

Alternatively, unlike the coating stripping operation by the automatic operation, the coating of the selected stripping position may be stripped by manual bar, and the stripping operation of the coating may be varied depending on the working environment.

In this case, the wire 50 may be generally two to four strands are drawn, but when the two strands are drawn as shown in Figure 3, as shown in the drawing, the coating stripping site that is subjected to coating stripping treatment on the wire 50 is similar. The coating was allowed to peel off at one location.

In addition, the position of the connecting pin 20 corresponding to the coating stripping part, that is, the position of the connecting pin 20 fixed through the printed circuit board 11 is also the same when the printed circuit board 11 is viewed from the top or bottom surface. It is desirable to ensure that they do not exist in the location and are set to similar locations.

The reason for doing this is that when the stripping treatment of the wire 50 may be in contact with other wires in which the adjacent sheath is stripped and a short circuit may occur.

As described above, the connection pin 20 of the printed circuit board 10 is mounted on the upper surface of the partition plate 33 of the case 30 and passes through the through hole 34 of the partition plate 33. When the state of contact with the coating stripping portion of the wire 50 is maintained, the contacting portion is soldered to prevent flow and at the same time, it is possible to conduct electricity, and the epoxy plate portion is epoxy-treated on the upper surface of the partition plate 33. 40 is formed, and then the epoxy molding part 40 is formed by epoxy treatment to the space below the case 30, and thus the lower epoxy molding part 40 is formed by the cover 60. The lower end of the 30 can be covered to implement a completed unitized state.

Unlike the present invention, as shown in FIG. 5, the connecting pin 20 is drilled through the holes 11 in the above-described printed circuit board 10 so that the hole 34 of the partition plate 33 is soldered without soldering the connecting pin 20. The connecting pin 20 is inserted into the soldering plate, and then the upper end portion of the connecting pin 20 is soldered in such a manner that the upper end of the connecting pin 20 is inserted into the hole 11 side of the printed circuit board 10. It is possible to obtain lighting means of the finished unit for application.
