More specifically, by configuring the first base and the second base separately, the substrate is composed of a separate layer of the outer layer and the inner layer can solve the problem of contact failures when contacting the conventionally configured socket-type substrate, many The LED of the present invention relates to an LED that can be easily separated from one substrate and lighted, and can be easily transformed into a form of the substrate itself on which the LED is installed to produce an excellent spectacular.

Temples often use various instruments, including lanterns and lanterns, to perform specific events or ceremonies. And lamps are used to illuminate events such as lanterns and lanterns.

In the past, candles were used to illuminate these events, but they were replaced by incandescent lamps because of fire hazards and failure to emit light for a long time. In addition, as disclosed in Korean Utility Model No. 033737 "Three-corporate lamps using high brightness light emitting diodes" and Korean Utility Model No. 033736 "molding lanterns" due to power consumption and heat generation problems, LEDs, that is, LEDs, Mainly used.

In the lamps used in the lanterns and the lights described above, the LED is directly connected to the cable or a structure through the printed circuit board connected to the cable, this structure is a way that the lead wire of the LED is soldered to the cable or printed circuit board If the LED is broken there was a problem that the replacement is virtually impossible.

There are improvements to the above problems, such as registered utility model No. 004087 "direct lighting lit directly", registered utility model No. 0425465 "a temple lamp with a waterproofing means", etc.

The LED disclosed in the related art has a structure in which the lead wire and the light emitting part are placed on the base, and the base is screwed to the socket, so that only the base on which the light emitting part is placed should be replaced when the LED is broken.

However, in the LED disclosed in the prior art, the lead wire forming the (+) or (-) part is electrically connected to the bottom of the base, and when it is fastened with the socket, an electrical connection with the bottom of the socket is required.

In the electrical connection, the bottom of the base and the bottom of the socket are not correctly contacted, that is, frequent contact failures occur frequently causing problems in light emission,

Also, for easy insertion into the socket and the electrical contact, the shape of the base where the light emitting part is placed becomes narrower in cross section, that is, the shape of the ordinary light is usually taken.

When fastening with the socket, there was a problem that can be easily released.

Furthermore, the LEDs disclosed in the related art have a structure in which lead wires, sockets, and bases are exposed to the outside and easily contact with moisture. In particular, moisture may easily penetrate through a gap between the socket and the base, causing electrical safety problems. There was a disadvantage.

Of course, when the base is coupled to the socket to solve the waterproof problem, it may be considered to have a case for sealing the space between the base and the socket,

Although there is an advantage that the waterproof performance can be ensured when the packing is provided, there is a problem in that the contact between the socket and the base is not accurately made due to the thickness or volume of the packing.

In particular, even in the case of installing a large number of LEDs at once, according to the prior art, there was a problem in that a partial contact failure occurred and a maintenance work must be performed every time.

In order to separate and turn on a large amount of LEDs, each of the electrically connected LEDs must be individually connected to each other, and there is a problem in that specific LEDs cannot be easily turned off and on.

The present invention is to solve the above problems, all the lead wires forming a (+) and (-) form a base configuration in two stages to induce easy electrical contact with the substrate, and electrically connected with the base The substrate to be connected is also formed in two stages of the outer layer and the inner layer to maximize the contact area for the electrical connection to facilitate the bonding with the substrate, but to provide an LED with excellent bonding performance.

In addition, specific insulation is formed between two-stage bases or two-stage boards or both, so as not to cause safety problems while increasing the electrical contact area, and to prevent a short circuit accident that may occur due to moisture penetration. The purpose of the present invention is not only to provide a separate waterproof means, but also to provide an additional insulation layer on the upper surface of the substrate, and to provide an LED which is finally guaranteed for safety in use.

Furthermore, in case of high heat generated in the LED, a separate cooling means is provided for heat dissipation.

According to the present invention, not only can the contact area of the lead wire for electrical connection be made to the maximum due to the two-stage base and the two-stage substrate connected thereto, but also the electrical connection is made due to the contact failure when bonding with the substrate. Solved the problem of not losing

Furthermore, LEDs with various colors can be easily turned on or off, and the shape of the substrate can also be transformed into various shapes without a bad contact with the base, thereby creating a beautiful spectacular view.

In addition, in order to ensure safety in use to provide a cooling means or a waterproof member, or a separate insulating layer

Eventually, even if fastening a large number of LEDs that emit a variety of colors in a wide array of substrates with a large area, some of them do not cause light emission problems due to poor contact, and can provide an LED that can be used safely without problems. It can be effective.

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

First of all, the LED according to the present invention will be commonly used for religious purposes such as Buddhist lanterns, lanterns, etc., but the scope of use is not limited thereto, and if it is necessary to install a large amount of LEDs in daily life, it can be used anywhere. Reveal that

1 illustrates a conventional LED configuration in which contact failure is a problem. As shown in the drawing, two contacts 71 'for electrical coupling with a base are provided inside a socket 70' corresponding to a substrate in the present invention. , 72 '). These two contacts are respectively connected to two conductors of the cable and in contact with two contacts 31 'and 32' formed on the base. Of course, the contacts 71 ′ and 31 ′ shown on the inner side of the socket and the outer side of the base among the two contacts are shown for explanation, and the inner side of the socket and the outer side of the base itself serve as contacts. It is common.

The base 30 'is electrically coupled to the socket by a screw, and the light emitting part 10' is placed inside the base.

The two lead wires 21 ′ and 22 ′ accommodated in the light emitting unit are connected to the two contacts of the base, respectively, and one of the two lead wires is connected to the protection resistor 80 ′. The protection resistor is to prevent the LED from being damaged by the surge voltage, which is a common configuration.

Of course, one of the two lead wires is connected to the (+) pole, the other is connected to the (-) pole, in the following for the sake of ease of explanation, the lead wires are connected to the outer surface of the base to make contact A description will be given with reference to 21 'as the first lead wire and the remaining lead wire 22' as the second lead wire.

In the above configuration, when the base 30 'is electrically connected to the socket 70', the contact 32 'of the base connected to the second lead 21' and the contact 72 'of the socket have good contact. There is a problem that is not made. That is, when the base 30 'is screwed to the socket 70' to be coupled to the socket 70 ', the bottom of the base on which the base 32' is formed and the bottom of the socket on which the socket 72 'is formed. Problems arise that the contact is not easy.

Furthermore, when the packing member is provided in order to solve the waterproof problem, the contact failure becomes more severe due to the volume or thickness of the packing member.

Accordingly, in the present invention, as shown in FIGS. 2 and 3, the configuration of the light emitting unit 10 and the lead wires 21 and 22 accommodated in the light emitting unit is the same as in the related art, but forms a contact with the lead wire and is electrically connected to the substrate. The base where the connection is made is separated into the first base 30 and the second base 40 separately. In addition, the substrate 70 may be separately separated into an outer layer 70a that forms an electrical coupling with the first base 30 and an inner layer 70b that forms an electrical coupling with the second base 40. Easy electrical connection and prevent contact failure.

The substrate mentioned in the above description is a configuration corresponding to a conventional socket, and in the following description of the present invention, it will be collectively described as a substrate. Of course, the manner in which the base is fastened to the substrate is, of course, employs a threaded coupling that is a method of fastening the base to the conventional socket.

More specifically, the first lead wire 21 according to the present invention is connected to the first base 30, and the second lead wire 22 is connected to the second base 40. As a result, the electrical contact area by the second lead wire 22 is increased due to the configuration of the second base 40, and the second base is not connected to a separate wire, as shown in FIG. Since the screw is coupled to the inner layer 70b, a wide contact area for electrical connection can be secured.

In particular, in this case, since the contact area for the electrical connection is wide, even if the size of the first base 30 and the second base 40 are different, it is easy if only the size of the fastening hole fastened to each base is the same. It is preferable because it can be combined so that a poor contact does not occur. More specifically, although the diameter size of the second base 40 located below is smaller than the diameter size of the first base 30 for easy insertion and fastening of the LED to the substrate, the first and second If only the diameters of the outer and inner fastening holes 71a and 71b corresponding to the base diameter are configured to be the same as the respective base diameters, the problem of poor contact does not occur.

As a result, the contact area is increased due to the configuration of the second base 40 connected to the second lead wire 22 and the configuration of the inner layer 70b coupled to the second lead wire 22, thereby reducing the possibility of a problem of contact failure. It is.

In addition, when the first base 30 is fastened to the substrate outer layer 70a by screwing, the second base 40 is satisfied if it is placed in contact with the substrate inner layer 70b. It is not necessary to form a screw thread on the outer circumferential surface of the second base and the inner circumferential surface of the inner fastening hole 71b of the substrate inner layer 70b, thereby reducing the manufacturing cost.

In addition, although the first base and the second base are spaced apart from each other at a predetermined distance from each other, as shown in Figure 2, it is provided with a separate insulation 50 to ensure structural stability and safety desirable. In addition, the insulating part will be described in more detail below, but it is preferable that the insulating part is separately provided between the inner layer and the outer layer.

Next, as shown in Figure 3a and 3b, the base consisting of two stages in contact with the lead wire is fastened to the substrate consisting of the outer layer and the inner layer,

A plurality of fastening holes 71a and 71b are formed in the substrate 70 to be fastened to the bases 30 and 40. That is, the first base is screwed with the outer fastening hole 71a formed in the outer layer, and the second base is screwed with the inner fastening hole 71b formed in the inner layer. However, as described above, the second base is enough to be placed in the surface contact with the inner fastening hole.

In this case, referring to FIG. 3B, the adhesion between the substrate and the substrate may be prevented from infiltrating moisture through a narrow gap between the first base 30 and the external fastening hole 71a. In the present invention, a waterproof member 60 for improving performance is provided under the light emitting unit.

The waterproof member may be embodied in various forms, but as shown in FIGS. 2 and 3, a narrow portion 60a formed at the lower portion of the light emitting part may be formed when the waterproof member is combined with the external fastening hole of the first base and the substrate. Make sure that the gap is completely sealed.

Of course, the upper surface of the outer layer of the substrate is preferably coated with an epoxy or the like for insulation, after all, the outer fastening hole 71a of the first base 30 and the substrate by the annulus 60a. The gap between them is sealed, and the insulating layer 72 coated on the surface is in contact with the outer circumferential surface of the annulus, thereby making it more waterproof.

In the present invention, although the waterproof member is shown as a round portion formed under the light emitting portion through FIGS. 2 and 3, it can be replaced by a packing inserted into the outer circumferential surface of the light emitting portion. In this case, considering the adhesion, rubber packing would be preferred.

Again, the configuration of the substrate will be described with reference to FIG. 3.

A plurality of fastening holes are formed in the substrate to insert various kinds of LEDs emitting various colors. As described above, the substrate is electrically connected to the first base to which the first lead wire is connected to solve the problem of contact failure. An outer layer 70a having a plurality of outer fastening holes for achieving a positive coupling, and an inner layer 70b having a plurality of inner fastening holes for electrical coupling with a second base to which a second lead wire is connected. Is done.

Furthermore, the outer layer 70a of the substrate is naturally composed of a conductor, but the inner layer 70b is composed of a non-conductor 78, and only the adjacent portion 75 where the inner fastening hole is formed is a conductor. desirable.

More specifically, referring to FIG. 4, which shows only the inner layer 70b, the inner layer 70b may be lighted so that the inserted LEDs emit light in a specific horizontal row, vertical column only, or diagonal line only. I need to configure

If the LED is to be arranged in a horizontal row, as shown in Figure 4, it is preferable to form adjacent portions 75 of the inner fastening hole formed of a conductor in a horizontal row form. Therefore, when the LEDs of a particular horizontal array are not desired to be turned on, if only the electrical connection of the unwanted array is cut off, the LEDs of the other horizontal arrays are turned on so that only the desired array is turned on.

If the inner layers are all made of conductors, the LEDs cannot be turned on or off in a specific arrangement, and this is because the LEDs need to be disconnected from each other.

Although the arrangement is illustrated in FIG. 4 to be lit in a horizontal row, this may be configured as a vertical column or a diagonal row according to a user's request.

Next, referring to FIG. 5, the substrate 70 has a curved surface, that is, a pipe shape, unlike the flat substrate shown in FIG. 3.

That is, as shown in Figure 5b, the inner layer (70b) and the outer layer (70a) of the substrate is configured in a pipe shape of the concentric circles of cross-section, the first and the first of the LED on the inner layer and the outer layer Since the method of fastening the two bases is the same as the method described with reference to FIG. 3, a detailed description thereof will be omitted.

However, in the case of taking the form of the substrate as shown in FIG. 5, it is because it is easy to install cooling means that can prevent excessive heat generation of the LED.

That is, the cooling means is implemented by passing the cooling water through the inner space 73 made by the pipe inner substrate 970b.

Therefore, as shown in Figure 5a, the coolant is introduced 91 to one side of the inner layer of the substrate forming a concentric pipe shape,

While the introduced coolant penetrates through the space 73 of the inner layer, excessive heat generation of the LEDs which come into contact with the inside is prevented and radiated, thereby being discharged to the other side 92.

Furthermore, the material of the substrate is preferably made of a flexible material to implement a free shape. Therefore, the present invention is not limited to the flat substrate shown in FIG. 3 and the pipe-shaped substrate shown in FIG. 5, and various shapes such as the folding or bending of the substrate can be realized.

This makes it possible to produce a beautiful minister.

In the above description, the first base is fastened to the substrate, and the light emitting part provided on the substrate is protruded to the outside of the substrate.

However, referring to FIG. 6, even when the LED is installed on the substrate, the thread 15 formed on the outer circumferential surface of the light emitting portion itself is formed on the outer circumferential surface of the light emitting portion instead of the first base portion to form the thread 15 for fastening with the fastening hole of the substrate. It can be fastened with the fastening hole of the substrate. Then, even the light emitting part of the LED is inserted into the substrate to produce a spectacular view of only the light emitted from the substrate.

Furthermore, since the thread 15 is formed on the outer circumferential surface of the light emitting part, when the LED light having the straightness comes into contact with the thread 15 of the light emitting part, the light is bent to emit light in various directions, so that the screw is fastened to the substrate. Not only that, but also the function of dispersing light.

In this case, in order to easily insert the light emitting unit into the substrate, the upper surface of the light emitting unit is preferably provided with a fastening portion 18 having a polygonal groove shape. That is, when the first base is inserted into the substrate, the operator may hold the light emitting portion and turn the LED to insert the LED into the substrate. However, in order to insert the light emitting portion itself shown in FIG. 6 into the substrate, the operator needs a separate fastening portion. When the fastening portion 18 having a polygonal groove shape is provided on the upper surface of the light emitting body, the operator inserts a fastening table having a cross section corresponding to the polygonal groove shape into the fastening portion of the polygonal groove and rotates the light emitting unit substrate. It can be easily inserted into.
