Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LED frame and a method of manufacturing the LED frame,

The present invention relates to a method of manufacturing an LED frame and an LED frame, and more particularly, to an LED frame and a method of manufacturing an LED frame.

In general, in a room lighting for a wide space, a lighting device for a raceway is generally adopted as a wiring tube body called a raceway.

In the method using a raceway, not only a wiring for a luminaire but also a wiring duct for various communication are installed in a ceiling. A luminaire is a method in which a luminaire is installed along the lower part of the wiring duct, The power cables to be supplied are housed in the wiring ducts in a lump, thus providing a cosmetic clean effect.

However, in the case of the laceway type luminaire, the alignment of the luminaire may be disturbed according to the position of the fastening hole in the process of installing each luminaire in the duct, and the luminaire and the wiring duct must be combined at the site. It is difficult to divide the space between the lighting frame and the wiring duct. Therefore, there has been a problem in that a separate wiring duct has to be used in order to accommodate the communication line in addition to the electric circuit.

Accordingly, the applicant of the present invention has made a patent application to carry out a series of inventions in order to overcome the disadvantages.

The present invention relates to a so-called wiring circuit integrated luminaire for connection installation, in which a lamp is housed in a frame to provide excellent space utilization, and a duct frame is provided with a simple structure of a lamp frame so that a separate installation is not required in the field, And it is not necessary to arrange the luminaire separately by using the structure. For example, in the case of Patent Registration No. 10-1294750 (Registration Date: 2013.08.02), Registration No. 10-0745194 (Registration Date: 2007.07.26), Registration No. 10-0745191 (Registration Date: 2007.07 Patent Registration No. 10-0820084 (Registration Date: Apr. 01, 2008), Patent Registration No. 10-1487340 (Registration Date: Feb. 21, 2015), etc. In 2013, It has received KS certification as an LED luminaire. 1 is a plan view of an integrated wiring circuit for a joint installation.

However, since the conventional LED frame 10 is formed by bending a single plate as shown in an exploded perspective view of Patent Document 10-1487340 shown in FIG. 1, when the LED frame 10 is injected for a long time in the extrusion process, There is a fear that bending may occur.

Therefore, it is possible to accommodate both the LED substrate, the power supply device and the wiring in the wiring duct so as to be usable in the integrated wiring circuit for the connection installation, while preventing the occurrence of the longitudinal bending in the extrusion process, It is required to provide a LED frame whose longitudinal bending can be prevented.

Patent Registration No. 10-1487340 (Registration date: Feb. 21, 2015)

The present invention has been made in order to solve the problems of the prior art, and it is an object of the present invention to provide an integrated wiring device for a connection wiring, which can accommodate both an LED substrate, a power supply device and a wiring in a wiring duct, And it is an object of the present invention to provide an LED frame capable of preventing the occurrence of bending and preventing longitudinal bending without a significant increase in the weight of the LED frame.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided an LCD module, comprising: a central horizontal plate having an LED substrate mounted on a bottom surface thereof and a heat radiating fin formed on an upper surface thereof; And a diffusion plate suspension part formed at the lower end of the side slanting plate and having bent portions of the LED diffusion plate slidingly coupled to each other so as to face each other,

And a reinforcing chamber formed integrally with the side wobble plate at a predetermined portion of the side wobble plate.

Here, the reinforcing chamber is preferably composed of an upper plate and a lower plate, and two vertical plates connecting both ends of the upper plate and the lower plate.

And the lower plate preferably forms a part of the side swash plate.

The two vertical plates are preferably a first vertical plate on the side of the central horizontal plate and a second vertical plate on the diffusion plate suspending unit side, and the length of the second vertical plate is longer than the length of the first vertical plate.

In this case, the upper plate may preferably be formed in a circular shape that curves toward the upper side.

On the other hand, the lower plate is preferably detachably formed in the reinforcing chamber, and an assembling projection is formed under the opposing faces of the first and second vertical plates to assemble both sides of the lower plate.

At this time, the auxiliary LED substrate is preferably inserted into the upper part of the opposing surface of the first and second vertical plates.

The LED frame according to the present invention has an effect of suppressing the occurrence of warping of the LED frame in the process of extruding the LED frame without a large increase in the weight of the LED frame. In particular, since the chamber top plate is formed in a circular shape, The length of the LED frame can be made much longer than that of the prior art. The flexural bending of the LED frame can be prevented by only adjusting the width of the second vertical wall, so that the manufacturing cost can be reduced by simplifying the design. It is possible to prevent bending of the LED frame in all cases by a simple design change corresponding thereto.

And should not be construed as limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

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

The description of the LED frame according to the present invention is based on the basic embodiment shown in Figs. 2 to 5, the first modified embodiment of Fig. 6, the second modified embodiment of Fig. 7, and the third modified embodiment of Fig. 8 .

Therefore, each embodiment will be described below in order.

≪ Basic Embodiment >

The basic embodiment is an embodiment in which the reinforcing chamber portion 20 is provided in the conventional LED frame shown in Fig. 2 to thereby form the LED frame of Fig.

3, the LED frame according to the present invention includes a central horizontal part 10, a reinforcing chamber part 20 on both sides of the central horizontal part 10, and a reinforcing part 20 connected to the outer lower side of the reinforcing chamber part 20 And a diffuser plate suspending section 30.

The central horizontal portion 10 is formed by the horizontal plate 11, the heat dissipation fin 13, and the substrate assembly protrusions 17. A substrate assembling protrusion 17 is formed on both sides of the horizontal plate 11 so that the LED substrate L is slidably coupled to the bottom surface of the horizontal plate 11. A plurality of heat dissipating pins (13) is protruded. At this time, two central heat dissipation fins 13 of the heat dissipation fins 13 may serve as bolt insertion slots 12 for inserting the preforming bolts (not shown) to suspend the structure of the LED frame itself in a special situation have.

The reinforcing chamber portion 20 is formed in such a manner that a compartment space which is closed on the upper side slanting plate 2 shown in FIG. 2 is formed as shown in FIGS. 3 and 4. Specifically, a top plate 23 connecting the two side plates and the tops of the two side plates is further formed to be formed as a chamber. The side plate is preferably formed of a vertical plate, and more preferably, a vertical length of the vertical plate farther from the central horizontal portion is formed to be longer than a vertical plate closer to the central horizontal portion 20.

For convenience of explanation, the vertical plate closer to the central horizontal part 20 will be referred to as a first vertical plate 21 and the vertical plate farther from the central horizontal part 20 will be referred to as a second vertical plate 22 .

The chamber is formed with a partition space in which the upper plate 23 and the first and second vertical plates 21 and 22 are closed together, so that the principle in which the longitudinal flexion of the LED frame does not occur during the extrusion process is shown in FIG. have.

The LED frame shown in Fig. 2 may be bent in the longitudinal direction during the extrusion process. In this case, when the reinforcing chamber portion 20 is formed, a load applied to the side wobble plate 2 in FIG. 2 is applied to the upper plate constituting the reinforcing chamber portion 20, and the upper plate 23 is divided into the first and second vertical portions By being supported by the plates (21, 22), the load capable of causing bending is effectively dispersed to prevent bending in the longitudinal direction.

Referring to FIG. 5, points P and Q are fixed in the LED frame discharged from the extruder M, and points S and R are subjected to a force to sag downward. 5, the upper portion is subjected to tensile force and the lower portion is subjected to compressive force.

Referring to the conceptual diagram of the distribution of the force acting on the reinforcing chamber portion 20 shown in the lower portion of FIG. 5, the largest tensile force is applied to the upper plate 23 in the reinforcing chamber portion 20. The tensile force applied to the upper plate 23 is a tensile force received by the side warp plate 2 in the conventional LED frame as shown in Fig. 2 without the reinforcing chamber portion 20. The side warp plate 2 shown in Fig. A tensile force is applied to the upper surface and a compressive force is applied to the lower surface, so that there is a possibility that the stress is concentrated on the thin thickness and warp or bend may occur.

However, as shown in the lower conceptual view of FIG. 5, the reinforcing chamber portion 20 is formed in the present invention, and the upper plate 23 constituting the reinforcing chamber portion 20 receives the tensile force instead, The lower plate 24 of the reinforcing chamber portion 20 is not subjected to a large tensile force.

In addition, since the first and second vertical plates 21 and 22 are spaced apart from each other by a predetermined distance or more between the upper plate 23 and the lower plate 24, the upper plate 23 receives the tensile force but does not receive the compressive force.

The tensile force is reduced from the upper part of the second vertical plate 22 to the lower part as shown in the drawing, and the lower end of the second vertical plate 22 is subjected to the compressive force rather than the tensile force. Since the vertical load is applied to both ends of the reinforcing chamber portion 20, when the LED frame is considered as an arbitrary fixed length, a vertical load is applied to both ends of the reinforcing chamber portion 20 by a predetermined length And a force is applied to the upper portion between both ends. 5, since the LED frame is going to rotate in the clockwise direction around the point Q, the force is applied to the upper direction at the point P, and the force is applied to the lower side The force applied to both ends of the LED frame is applied to the center of the LED frame so that upward force is applied to the center of the LED frame. Thus, in the conceptual view of the lower part of FIG. 5, At both ends, a load is applied to the lower part, and a force is applied to the upper part at the center.

In this case, if the first and second vertical plates 21 and 22 are formed in an inclined shape other than vertical, the distance that the tensile force generated by the force applied to the lower portion and the force applied to the upper portion changes to the compressive force, Since only the thickness of the vertical plates 21 and 22 is generated, there is a high possibility that the first or second vertical plates 21 and 22 are bent.

However, when the first and second vertical plates 21 and 22 are formed vertically as in the name, the distance that the tensile force is changed to the compressive force becomes longer by the width distance of the first and second vertical plates 21 and 22, This occurrence is suppressed as much.

Therefore, when the reinforcing chamber portion 20 is provided, the tensile force to be received by the side warping plate 2 in FIG. 2 is received by the upper plate 23 constituting the reinforcing chamber portion 20, and the distance by which the tensile force is changed into the compressive force, Since the lower plate 24 receives only the compressive force, the bending caused by the sudden change of the tensile force to the compressive force as in the conventional LED frame can be remarkably suppressed.

As described above, the larger the width of the first and second vertical plates 21 and 22, the more easily the occurrence of the bending can be prevented. However, the widths of the first and second vertical plates 21 and 22 If both are increased, the total load of the LED frame is increased together, so that the material cost increases due to the increase of the amount of material required, and the load is increased and the possibility of bending due to the increase is increased.

Therefore, in the present invention, since the width of any one of the first and second vertical plates 21 and 22 is longer than that of the first vertical plate 21 and the second vertical plate 22, . That is, the width of the second vertical plate 22 is longer than the width of the first vertical plate 21. This is because the first and second vertical plates 21 and 22 must be bent together in order to cause bending, so that if the width of one of the first and second vertical plates 21 and 22 is large, .

In this case, the width of the second vertical plate 22 is preferably made larger. 3, if the width of the first vertical plate 21 is larger than that of the second vertical plate 22, the width of the first vertical plate 21 may be larger than the width of the first vertical plate 22. In this case, Since the LED frame protrudes to the upper portion of the wiring duct (20 in Fig. 1) by an increased height of the first vertical plate 21 due to a difference in height between the lower end of the first vertical plate 21 and the lower end of the second vertical plate 22, 1 20) inner space becomes narrower, resulting in a reduction in the power supply device (not shown) and the wiring storage space and the heat dissipation space.

3, when the width of the second vertical plate 22 is greater than the width of the first vertical plate 21, the height of the upper end of the second vertical plate 22 is greater than the width of the central horizontal portion 10, It is possible to achieve a sufficient bending prevention effect without exceeding the height of the curved surface.

Therefore, in the present invention, the width of the second vertical plate 22 is preferably larger than the width of the first vertical plate 21.

Further, in manufacturing the LED frame, the unit load according to the material, size, shape and length of the LED frame is determined, and the limit of the yield tensile strain that can be generated in one LED frame is larger than the unit load The width of the second vertical plate 22 is calculated and applied so that it is possible to manufacture an LED frame in which the width of the second vertical plate 22 is prevented from being bent.

<First Modified Embodiment>

The first modified embodiment is similar to the first embodiment except that a material heavier than the material of the LED frame used in the above-described basic embodiment is used, or when a material having a high elongation strain is used, (22) is further increased.

As a result, when the possibility of occurrence of bending is high, the possibility of occurrence of bending can be reduced by increasing the width of the second vertical plate 22. Therefore, the calculation result from the strength characteristics of the material and the length and load of the LED frame, The possibility of occurrence of bending can be prevented by adjusting the width size of the vertical plate 22. [

That is, the first modified example increases the possibility of bending that may occur in the extrusion process when the LED frame is to be made longer than that in the basic embodiment. To prevent this, the width dimension of the second vertical plate 22 . However, even if the width of the second vertical plate 22 is increased more than that of the basic embodiment, the second vertical plate 22 is positioned lower than the first vertical plate 21, Does not exceed the height of the upper end of the projection formed for the bolt insertion slot 12 which is the upper end of the central horizontal portion 10, so that the inner space of the wiring duct (20 in FIG.

&Lt; Second Modified Embodiment &

The second modification is an embodiment in which the possibility of occurrence of bending is further reduced by manufacturing the shape of the upper plate 23 constituting the reinforcing chamber portion 20 in a circular or arch shape.

The upper plate 23 in the form of an arcuate or circular shape uniformly distributes the load applied from the upper portion of the upper plate 23 as in the case of an architectural structure to prevent breakage or bending that may occur due to concentration of stress concentration in a certain portion It is a structure that can be.

In the case of the present invention, a load according to the length of the unit LED frame is generated by the left and right pulling forces in the upper plate 23, though not the load applied at the upper portion. In this case, the first and second vertical plates 21 , 22).

When the tensile force is applied to the upper ends of the first and second vertical plates 21 and 22, when the first and second vertical plates 21 and 22 are excessively wide or thin, The buckling of the first and second plates 21 and 22 may occur. In this case, if the upper plate 23 is formed in a circular or arch shape as in the second modification shown in FIG. 7, the tensile force is evenly distributed over the upper plate 23, so that the first or second vertical plates 21, Thereby preventing buckling which may occur in the case of the present invention.

&Lt; Third Modified Embodiment &

8, the auxiliary LED substrate L-2 is mounted inside the reinforcing chamber portion 20, and the lower plate 24 constituting the reinforcing chamber portion 20 is detachably installed The auxiliary LED substrate L-2 is driven by the removal of the lower plate 24 so that the additional light source can be irradiated.

The luminaire may require additional light sources depending on the installation location or time and circumstances. In this case, it is possible to accomplish this purpose by tightening the spacing of the luminaire. However, when light sources of different brightness are required depending on time and situation, installation and material cost increase may be considerable due to a compact luminaire.

Accordingly, the present invention proposes an embodiment in which an auxiliary light source can be installed as well as an increase in yield strength by using the reinforcing chamber portion 20 for preventing the flexion of the LED frame, thereby providing an additional light source installation without additional additional luminaire .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
