Description

Method of Assembling LED Light Fixture with Printing Sheet

The present invention relates to an LED lighting fixture including a printed pattern sheet and an assembling method thereof, and more particularly, there is no room for impurities such as fine dust to intervene in the process of assembling the LED lighting fixture, and the assembling process is simplified It relates to a method of assembling an LED lighting fixture including a printed pattern sheet that can be performed and can greatly improve work efficiency.

Today, indoor lighting has been changed from incandescent lamps to fluorescent lamps and then to LED lighting lamps.

LED lighting has been developed thanks to the development of semiconductor technology, and is rapidly replacing conventional fluorescent lighting based on high energy efficiency.

An LED lighting lamp uses light emitted from an LED (Light Emitting Diode) semiconductor, and can be divided into a direct method and an edge method using a light guide plate depending on the installation method of the lighting source. The direct method uses the light emitted from the LED light source as it is to illuminate the room, whereas the edge method uses the light emitted from the LED light source and reflected by the light guide plate to illuminate the room.

In the case of indoor lighting, since the light emitted from the LED light source is very intense, in general, the edge method is mainly used rather than the direct method.

In addition, in the case of indoor lighting, the light emitted from the LED light source can be used as it is, but in order to demonstrate the efficiency of indoor lighting and the effect of interior decoration, it can be used as a tool to implement interior design using the light emitted from the lamp itself. may be

The edge-based indoor lighting fixtures commonly used today include an external frame that determines the overall shape or form of the lighting fixture, and an LED mounted on both sides of the frame and an LED light source and a printed circuit board electrically connecting it. A light source unit, a light guide plate that refracts the light emitted from the LED light source in a direction perpendicular to the traveling direction, and a light guide plate that is located on the back side of the light guide plate and reflects the incident light from the light guide plate and supplies it to the front side of the light guide plate and a protective plate installed on the back side of the light guide plate and formed of a thin metal plate, and a diffusion plate for scattering and diffusing the light refracted by the light guide plate and the light coming from the reflecting plate.

In such an edge-based indoor lighting fixture, in a state in which the LED light source unit is mounted on both sides of the outer frame, the protection plate, the reflector, the light guide plate, and the diffuser plate are placed face to face, and in that state, they are inserted into the LED light source unit. Assembled and finished products are being produced.

Such a conventional manufacturing method of LED lighting equipment inevitably has the following disadvantages.

First, the working conditions are very demanding, so the working productivity is very low. This is because the amount of light bent and emitted from the light guide plate varies according to the mounting distance of the LED light source and the light guide plate that comes in close contact with it, so the mounting distance must be precisely adjusted. In addition, it is necessary to precisely match the contact points of the light guide plate and the reflector and diffuser plates that come into contact with the rear and front surfaces thereof, since it is difficult to easily align the contact points without a skilled technician.

In addition, the conventional LED lighting fixtures inevitably have a very high rate of defective products due to the intervention of contaminants generated during operation. An LED lighting lamp inevitably uses a light guide plate, a reflector plate, and a diffuser plate. This is because, when foreign substances intervene in the assembling process, bad products are generated due to severe distortion or scattering of light. In order to reduce the possibility of such a defect rate, the work of assembling or attaching the light guide plate, the reflection plate, and the diffusion plate, etc., should be performed in a kind of clean room. Since such a clean room is possible only by removing contaminants or dust from the inside air, it is necessary to invest a lot of money to install it, and it is not easy for assemblers of LED lighting and the like to install such facilities. In addition, even when it is installed, the working conditions still have a difficult disadvantage.

As such, it is considered that there are many points to be improved in the manufacturing method of the conventional LED lighting fixture.

The prior art related to LED lighting seems to be as follows.

The present invention provides a method of assembling the edge-type LED lighting fixture (100).

The method of assembling an LED lighting fixture according to the present invention includes an external frame 10, an LED light source unit 20 mounted on the external frame, a light guide plate 30 that refracts the incident light of the light source unit, and a back surface of the light guide plate. It includes a preparation step (S110) of preparing the padded reflector 40 and the diffuser plate 60 padded on the front surface of the light guide plate and starting the assembly operation.

The outer frame 10 determines the shape of the exterior forming the lighting lamp, and has various parts of the lighting fixture built therein. The outer frame 10 generally has a rectangular shape, and has a shape in which the LED light source unit 20 is mounted on both sides of the inside. The outer frame 10 forms an inner fitting portion 12 as a means for safely inserting and fixing the LED light source unit 20 .

The LED light source unit 20 converts electric energy supplied from the outside into light energy, and emits the light energy to illuminate the interior of the room. In general, when the LED light source unit 20 puts the p-type semiconductor and the n-type semiconductor face to face and applies DC power to the semiconductors, electrons are ejected from the n-type semiconductor and transition to the hole of the p-type semiconductor, and the In the transition process, light energy is generated due to the lowered electron orbit, and the light energy is emitted to the outside to generate light of a specific wavelength.

According to this principle, light of different wavelengths is emitted according to the level of light energy generated from the semiconductor or semiconductor diode, and the light energy emitted to the outside passes through the protective material surrounding the semiconductor, and finally the LED light source unit 20 It is known to determine the light of

The LED light source unit 20 is inserted into the inner fitting portion 12 of the outer frame 10 and fixed, and an LED optical device 22 that converts electric energy into light and emits light, and the LED optical device It includes a PCB board 24 that transmits electrical energy to 22 . The PCB board 24 converts electric energy supplied from the outside into direct current, and performs a function of electrically connecting and controlling each LED element. The LED optical elements 22 are arranged in a line at regular intervals along a long and thin rod shape, and are detachably fixed to the inside at both sides of the outer frame 10 .

The light guide plate 30 is composed of a transparent acrylic panel that refracts and outputs light incident from the light source unit. A dot matrix shape is output on one surface of the light guide plate 30 or a groove is dug in the form of a V line, so that the light incident from the light source unit 20 is refracted to go out to the other side.

The reflective plate 40 refers to a sheet-shaped thin film plate that reflects the refracted and incident light in the opposite direction when the light generated by the light source unit 20 is partially refracted by the light guide plate 30 . The reflective plate 40 is installed on one surface of the light guide plate 30 , which is installed in the direction in which the point or V-shaped cutting surface is formed.

The protective plate 50 is present in the back of the reflective plate 40, can resist external forces, and must be able to protect the reflective plate 40 existing therein, so it is generally a thin plate made of a metal material. It can be manufactured and used in the form of

The diffusion plate 60 is installed on the other surface of the light guide plate 30 , and is installed on the opposite side of the reflection plate 40 . The diffusion plate 60 does not pass the light directly refracted from the light guide plate 30 and the incident light reflected from the reflection plate 40 as it is, but scatters therein so that the light is a point light source or rotational beam. By converting the shape of a circle to the shape of a surface light source, it makes it possible to achieve indoor lighting.

The present invention prepares each of the parts necessary for the manufacture of such an LED lighting fixture, and acts to assemble them.

The present invention includes a designing step (S 120) of the diffusion plate for forming a design pattern on one surface of the diffusion plate (60).

In the designing step (S 120) of the diffuser plate, one surface of the diffuser plate 60 is cleaned, and a design pattern including a portrait, a character, a natural landscape, or a picture is formed on the surface of the diffuser plate 60. ) to function as a means of providing design patterns. It is preferable to form a design pattern on one surface of the diffusion plate 60, and when the design pattern is formed on both sides, it is preferable that the design patterns do not interfere with each other. The design pattern formed on one surface of the diffusion plate 60 is preferably formed on the surface that is in close contact with the light guide plate 30, and in such a case, there is an advantage in that it is not affected by external scratches or marks.

The present invention includes a provisional bonding step (S 130) of temporarily bonding the reflecting plate 40 and the diffuser plate 60 to the rear and front surfaces of the light guide plate 30 as the center, respectively.

In the temporary adhesion step (S 130), first, one surface of the reflective plate 40 is cleaned and a first adhesive is applied to the surface. The first adhesive may be applied or painted only on the entire or part of the cleaned surface of the reflective plate 40 . The first adhesive is preferably capable of enhancing the adhesion between the plastic and the plastic or the adhesion between the plastic and the metal. In addition, it is preferable that the first adhesive exhibits adhesive force when heated, or can exhibit adhesive force when irradiated with light of a specific wavelength.

In the temporary adhesion step (S 130), one surface of the diffusion plate 60 is cleaned and a second adhesive is applied to the surface. The second adhesive may be applied or painted only on the entire or part of the cleaned surface of the diffusion plate 60 . It is preferable that the second adhesive can also strengthen the adhesion between the plastic and the plastic or the adhesion between the plastic and the metal. The second adhesive may be the same as or different from the first adhesive described above.

In the provisional bonding step (S 130), then, with the light guide plate 30 as the center, the reflecting plate 40 is temporarily bonded to one surface thereof, and the diffusion plate 60 is applied to the other surface on the opposite side. join together Temporary bonding includes temporary bonding.

In the temporary adhesion step S 130 , the first pointing point 30A of the light guide plate 30 , the second pointing point 40A of the reflecting plate 40 , and the third pointing point 60A of the diffuser plate 60 ) It is preferable to temporarily join in a state in which they coincide with each other. In the present invention, the light generated by the LED optical elements 22 is incident on the light guide plate 30, and the incident light is refracted inside the light guide plate 30, so that the light is incident on the reflection plate 40. This is to realize the most optimal incident angle condition in consideration of being reflected or being incident on the diffusion plate 60 and being diffused there.

To explain this in more detail, since the light refracted by the light guide plate 30 is incident on the reflection plate 40 , the angle of incidence of the light incident on the reflection plate 40 is very important. This varies depending on how the light guide plate 30 and the reflector plate 40 are coupled, and it is a fact of the prior art that the optimal coupling conditions are matched by the long experience of skilled workers. . This relationship may be equally applied to the coupling relationship between the light guide plate 30 and the diffusion plate 60 .

According to the present invention, the light guide plate 30 and the reflector plate 40 are the contacts that optimally meet the conditions by measuring the amount of light of the finished product that is actually combined with the experiences made by experienced workers by experienced workers. and the diffusion plate 60 are marked at appropriate positions, and the marked positions are marked with the first indicating point 30A, the second indicating point 40A, and the third indicating point 60A, It is intended to perform the provisional bonding operation in a state in which it is precisely aligned. The first indication point 30A, the second indication point 40A, and the third indication point 60A are preferably marked as two or more and plural, respectively, and are coupled at a point corresponding to each other at a point corresponding to each other. It is good to do the work.

As a result, according to the present invention, by making the first indication point 30A, the second indication point 40A, and the third indication point 60A exactly match and provisionally bonding, in the prior art, it must be done by skilled artisans. It can be said that the work that should have been done is no longer needed, and by adopting such a temporary joining method, the problems of the prior art are solved at once.

The present invention forms an adhesive force by curing the adhesive in a state in which the reflecting plate 40, the light guide plate 30, and the diffusion plate 60 are temporarily bonded to each other, thereby ultimately making a single integrated refractive reflector 80. It includes a forming step (S140) of the refracting plate.

In the step of forming the single refractive reflector ( S140 ), the reflector 40 , the light guide plate 30 , and the diffuser plate 60 are converted from a state in which they are temporarily adhered to each other to a complete adhesion state. This may be done differently depending on the performance of the adhesive. When the adhesive is a heat-curable adhesive, curing reaction is performed by heating the temporarily adhered reflector 40, light guide plate 30, and diffuser plate 60, whereas when the adhesive is UV-curable, the temporary adhesive The reflective plate 40, the light guide plate 30, and the diffuser plate 60 are irradiated with ultraviolet rays to proceed with the curing reaction. On the other hand, if the adhesive is a special-purpose adhesive that is cured in response to a specific substance, it will be natural that the work of implementing the adhesive performance is performed by adding such a specific substance.

After the step of forming the single refractive reflector (S140) is passed, the reflector 40, the light guide plate 30, and the diffuser plate 60 are integrated to form a new integrated refractive plate having the shape of a single thin plate material. A reflecting plate 80 is obtained.

The refractive reflector 80 obtained in the present invention has a design pattern including a portrait, a character, a natural landscape, or a picture therein, and this design pattern is between the light guide plate 30 and the diffuser plate 60 . is formed in When the light is irradiated by the LED light source 20, the design pattern provides a very subtle and beautiful design aesthetic to the room, so that the present invention can function as an interior interior product.

The present invention includes a complete assembly step (S 150) of a lighting lamp in which the single integrated refracting reflector 80 is inserted into the outer frame 10 and coupled thereto.

Since the complete assembly step (S 150) of the lighting lamp is to insert the single refracting plate 80 into the external frame 10 in which the LED light source 20 is embedded, the operator can easily perform the operation.

When the single refractive reflector 80 is inserted into the outer frame 10 , the single refractive reflector 80 is inserted into the inner fitting part 12 and fixed.

In addition, in the present invention, it is more preferable to make and use the single refractive reflector 80 by bonding the protective plate 50 together in the forming step (S140) of the single refractive reflector.

Since the other parts are made of a plastic sheet material, the protective plate 50 is preferably formed of a thin metal plate, and is preferably used by attaching it to the back surface of the reflecting plate 40 . The third adhesive 52 and the bonding method of the protective plate 50 and the reflecting plate 40 are the same as or substantially the same as described above.

When the protection plate 50 is adhered, the four individual sheet-shaped parts are converted into a single sheet shape and used, so it will be the most convenient and efficient method.

The present invention provides an LED lighting fixture 100 obtained by the assembling method described above.

The LED lighting fixture 100 according to the present invention includes an external frame 10, an LED light source unit 20 mounted on the external frame, a light guide plate 30 that refracts incident light from the light source unit, and a pad on the back side of the light guide plate. includes a reflective plate 40 and a diffuser plate 60 padded on the front surface of the light guide plate.

The LED light source unit 20 is inserted into the inner fitting portion 12 of the outer frame 10 and fixed, and an LED optical device 22 that converts electric energy into light and emits light, and the LED optical device It includes a PCB board 24 that transmits electrical energy to 22 . The principle of generating light from the optical element 22 is the same as described above.

The light guide plate 30 includes a first adhesive layer 42 between the light guide plate 30 and the reflector plate 40 , and the first adhesive layer 42 is a process in which the light guide plate 30 and the reflection plate 40 are completely in close contact with each other. It is connected in the state. The first adhesive layer 42 is preferably a transparent adhesive, and may be cured by heating or cured by irradiating light or ultraviolet rays.

In addition, the light guide plate 30 includes a second adhesive layer 62 for bonding the diffusion plate 60 to each other in close contact with each other, and the second adhesive layer 62 includes the light guide plate 30 and the diffusion plate ( 60) are combined in a state in which they are completely in close contact with each other. The first adhesive layer 42 and the second adhesive layer 62 may be the same as or different from each other.

The light guide plate 30 , the reflector plate 40 , and the diffuser plate 60 are integrally coupled to each other to form an integrated refractive reflector 80 . A first adhesive layer 42 is formed between the light guide plate 30 and the reflection plate 40 , and a second adhesive layer 62 is formed between the light guide plate 30 and the diffusion plate 60 . .

The integrated refracting plate 80 is inserted into the inner fitting portion 12 of the outer frame 10 . In addition, since the integrated refracting plate 80 includes design patterns such as portraits, characters, or natural landscapes therein, the design patterns provide an interior effect indoors through the diffusion plate by the light generated from the light source unit. and is protected from external scratches or stimuli by the diffusion plate. Accordingly, when the integrated refracting plate 80 is used as a component of an indoor lighting, it can provide a function as an indoor decoration product.

According to the present invention, since the conventional three to four sheet-shaped parts are manufactured as one single sheet-shaped part, there is no need to provide a separate clean room, and contaminants such as dust or hair are removed between the parts. It has the advantage of not having to worry about getting in.

In addition, in the present invention, it is no longer necessary to match the coupling position of the light guide plate 30 and the reflecting plate 40, even if not a skilled person, and it is also necessary to match the coupling position of the light guide plate 30 and the diffuser plate 60 Since there is no such thing, the work speed can be improved that much.
