Description

Technical Field [0001] The present invention relates to a lighting apparatus and a manufacturing method thereof,

The present invention relates to a lighting apparatus and a method of manufacturing the same, and more particularly, to a lightweight lighting apparatus which can be used as an advertising signboard and can be easily manufactured, and a method of manufacturing the same.

In general, the advertisement signboard is equipped with a lighting device so as to attract people's attention even at night. In the advertisement signboard provided with the illumination device, there are a type in which light is illuminated directly on a simple plate- And a light emitting part is provided in the interior of the signboard to emit characters and patterns written on the surface of the signboard, and a letter or pattern itself is formed in three dimensions, and a light emitting part is provided therein, There is a type.

Of the three types of advertisement signboards, the most frequently used signboards are face light-emitting channel signboards, because letters and patterns themselves are brightly illuminated, which can effectively attract people's attention (see Japanese Patent Application Laid-Open No. 10-2011-0084599 , July 26, 2011).

In the conventional surface light-emitting channel signboard, a steel plate is cut, bent, bent, and welded to form an outline shape of a character or a pattern, and a light emitting portion is provided in the inner space. Then, a resin such as epoxy Many are manufactured by injection molding. In addition, a method of covering a lid of a transparent material, through which light can pass, with a letter frame or a patterned iron frame may be used after a steel frame is formed according to the shape of letter or pattern and a light emitting portion is provided inside the frame.

However, such a conventional surface light-emitting channel signboard uses a steel material to make a character or a pattern, and thus has a problem of high manufacturing cost. In addition, since the conventional surface light emitting channel signboard is heavy, when the corrosion occurs due to outdoor rain, the bonding area with the signboard frame is weakened, and the water drops down into the inside of the surface light emitting channel signboard, There is also.

On the other hand, in the case of a conventional surface light-emitting channel signboard in which a resin such as epoxy is injected into the internal space of the door, injection of resin is considerably cumbersome and takes a lot of time and productivity is very low. In addition, if the resin is not injected at a uniform velocity, the light emitting surface may be bent or layered, which may not only damage the appearance but also cause a problem of poor light diffusibility.

In addition, since the conventional surface light-emitting channel signboard uses a steel material to form a character or a pattern shape roughly, only the front surface of a character or a pattern illuminates, and the side of a character or pattern does not emit light at all. There are restrictions on designing signs.

In addition, there is a critical limitation in the production cost, which is very inadequate for mass production, because the steel has to bend, bend and weld individually to make the basic shape of letters and patterns.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

In the drawings, the size of each element or a specific part constituting the element is exaggerated, omitted or schematically shown for convenience and clarity of description. Therefore, the size of each component does not entirely reflect the actual size. In the following description, it is to be understood that the detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a perspective view of a lighting apparatus according to the present invention, FIG. 2 is a cross-sectional view and a partially enlarged view taken along a line II-II 'of the lighting apparatus of FIG. 1, And the sidewall portion is machined.

1 to 3, the lighting apparatus according to the present invention includes a bottom plate 10, a cover plate 20, a side wall 30, and a light emitting unit 40.

The bottom plate 10 has a smaller thickness in the up-and-down direction than the width in the transverse direction, and is therefore formed into a generally flat plate-like shape as shown in Fig.

Since the cover plate 20 is located above the bottom plate 10 while being spaced apart from the bottom plate 10 and has a smaller thickness in the vertical direction than the width of the bottom plate 10 as in the case of the bottom plate 10, And is formed in a plate shape.

Since the lighting apparatus according to the present invention is formed to have a three-dimensional character or pattern shape, the bottom plate 10 and the cover plate 20 have shapes corresponding to each other. More specifically, when the bottom plate 10 and the cover plate 20 are overlapped, they have the same shape. For example, in FIG. 1, the bottom plate 10 has the shape of the numeral '9' and the cover plate 20 has the shape of the numeral '9'.

The side surface of the bottom plate 10 is inclined so that the area of either one of the upper surface and the lower surface is wider or narrower than the area of the other surface. 2, the bottom surface of the bottom plate 10 is larger than the top surface of the bottom plate 10 because the bottom surface of the bottom plate 10 has a longer trapezoidal shape than the upper surface. Likewise, the side surface of the cover plate 20 is inclined such that the area of either the upper surface or the lower surface of the cover plate 20 is wide or narrow.

2, an acute angle of the angle between the side surface of the cover plate 20 and the horizontal plane is represented by?, And the side surface of the bottom plate 10 is also inclined to form an angle with the horizontal plane. Here, theta is preferably 60 DEG to 80 DEG, more preferably 70 DEG.

Since the side surfaces of the cover plate 20 and the bottom plate 10 are inclined in this manner, it is easy to attach the cover plate 20 or the bottom plate 10 to the side wall portion 30. [ However, in the case of the bottom plate 10, the angle? May be formed to be 90 degrees in order to increase the strength of connection with the side wall portion 30.

The fact that the side surfaces of the cover plate 20 and the bottom plate 10 are inclined makes it easy to attach the cover plate 20 or the bottom plate 10 to the side wall portion 30 will be described later.

The side wall 30 connects the bottom plate 10 and the cover plate 20 so that the cover plate 20 and the bottom plate 10 are kept apart from each other. That is, the side wall portion 30 is positioned to surround the bottom plate 10 and the cover plate 20.

The side wall portion 30 includes a base plate 32 having an elongated band shape and a pair of protruding portions 32b protruded from the base plate 32 by being bent from both ends in a width direction perpendicular to the longitudinal direction of the base plate 32. [ Two outer rails 34 and two inner rails 36 spaced inwardly from the two outer rails 34. The outer rails 34 and the inner rails 36 are formed along the longitudinal direction of the base plate 32 and the inner rails 36 are projected in the same direction as the outer rails 34. The groove formed in the space between the outer rail 34 protruded from the base plate 32 and the inner rail 36 protruding from the base plate 32 is referred to as a rail groove 38, 38, the bottom plate 10 and the cover plate are fitted.

It is preferable that the inner rail 36 further protrudes from the base plate 32 than the outer rail 34. This can be confirmed by the fact that L2 is longer than L1 in the partial enlarged view of FIG.

The light emitting portion 40 is a member that emits light and is installed in a space defined by the bottom plate 10, the cover plate 20, and the side wall portion 30. [ In other words, it is installed in the inner space of the lighting apparatus according to the present invention. 2, the light emitting unit 40 is disposed on the top surface of the bottom plate 10, but the inner side of the side wall unit 30 may be a position where the light emitting unit 40 can be fixed, It can be installed wherever space is available.

Generally, the light emitting unit 40 uses an LED module including an LED device and a circuit board on which the LED device is mounted. However, in addition to LED modules, various lights including fluorescent lamps, incandescent lamps, and halogen lamps may be used.

A wiring is connected to a light emitting portion 40 provided inside the lighting apparatus according to the present invention. When a lighting apparatus is installed on a wall or a signboard, a penetrating hole is drilled through the invisible bottom plate 10, Power can be supplied to the light emitting portion 40 by removing the wiring through the hole.

Unlike conventional channel signboards, which use bolts or the like to assemble a member constituting a channel signboard, the lighting device according to the present invention can be assembled and manufactured using only an adhesive without using any bolts or the like. That is, adhesive is injected between the bottom plate 10 and the rail grooves 38 located at the upper portions of the side wall portions 30 and the rail grooves 38 located at the lower portions of the cover plate 20 and the side wall portions 30, The bottom plate 10 or the cover plate 20 is firmly coupled to the rail groove 38. [0031] As shown in FIG. Further, since the present invention does not use iron, no troublesome process such as welding is required at all. In addition, since the lighting apparatus of the present invention does not require the formation of bolt fastening holes for fastening bolts, water can be prevented from flowing into the lighting apparatus through the bolt fastening holes, The waterproof performance is excellent.

The bottom plate 10, the cover plate 20 and the side wall 30 of the present invention may be formed of a synthetic resin material and may be made of polycarbonate (PC). Since the polycarbonate material does not cause melting even when a high temperature is emitted from the light emitting portion 40 and is almost discolored due to direct sunlight unlike polystyrene and polyethylene which are discolored when exposed to direct sunlight for a long time, When the plate 10, the cover plate 20, and the side wall 30 are formed, the lifetime of the lighting apparatus is prolonged. Further, since no iron material is used at all, it is possible to reduce the weight of the lighting apparatus, and there is no fear of corrosion.

On the other hand, when the channel signboard according to the related art is installed on the wall, the channel signboard itself is formed in a cubic shape, but since the light is emitted only from the front face, There was a limit to the number. However, since the illumination device according to the present invention is formed of a transparent material, the light emitted from the light emitting portion 40 is transmitted through the bottom plate 10, the cover plate 20, the side wall portion 30, I can go out. Therefore, the lighting apparatus according to the present invention has an advantage that the visibility is superior to the conventional art.

In order to make the light emitted from the light emitting portion 40 not surface light but surface light, the present invention may be formed of a light diffusion polycarbonate material, or a transparent polycarbonate material, and the surface thereof may be covered with a light diffusion sheet.

1, since the polycarbonate has elasticity, the base plate of the side wall portion 30 can be curled around the bottom plate 10 and the cover plate 20 even when the base plate is bent, have. 2, the outer rail 34 protrudes by L2 and the inner rail 36 protrudes by L1 smaller than the outer rail 34 and the inner rail 36 by L2 The base plate 32 of the side wall portion 30 can be more easily bent.

Here, when the lighting apparatus according to the present invention is used for a channel signboard of a conventional size, for example, L1, which is the protruded size of the outer rail 34 located at the upper and lower portions of the side wall portion 30, And L2, which is the protruded size of the inner rail 36 located at the upper and lower portions of the side wall portion 30, may be formed to be about 3 mm. In FIG. 2, the outer rail 34 located at the upper and lower portions of the side wall portion 30 And the sizes of the inner rails 36 located at the upper and lower portions of the side wall portion 30 are the same. The inner rail 36 located at the lower end of the side wall portion 30 is longer than the inner rail 36 located at the upper end of the side wall portion 30 in order to more firmly engage the bottom plate 10 and the side wall portion 30 . For example, when the inner rail 36 located at the upper portion of the side wall portion 30 protrudes by about 3 mm, the inner rail 36 located at the lower portion of the side wall portion 30 may protrude by about 4.5 mm.

However, it is difficult to completely cover the peripheries of the bottom plate 10 and the cover plate 20 by merely bending the side wall portions 30 at the portions where the portions are suddenly bent, such as portions B and C in Fig. Thus, the wedge-shaped cutting process is performed on the B and C portions of the outer rail 34 and the inner rail 36 of the side wall 30. The state in which the wedge-shaped cutting process is performed is shown in Fig. Before wrapping the periphery of the bottom plate 10 with the side wall portion 30, the B portion and the C portion of the outer rail 34 and the inner rail 36, which are to be abruptly bent in the side wall portion 30, The side wall portion 30 can be brought into close contact with the bottom plate 10 and the cover plate 20 while being bent without causing any problem in the portion where the side wall portion 30 is bent. If the angle at which the sidewall portion 30 is bent is increased, the angle? Between the cut-formed portion of the wedge-shaped portion may be made larger.

4 is a view showing a manufacturing method of a lighting apparatus according to the present invention.

Hereinafter, with reference to FIG. 4, a description will be given of a manufacturing method of a lighting apparatus according to the present invention.

A bottom plate 10 and a cover plate 20, which can overlap each other in the same shape and are smaller in vertical thickness than the lateral width, are provided.

First, the bottom plate 10 is placed on a floor or a flat work bench.

Then, the periphery of the bottom plate 10 is wrapped and fixed by the band-shaped side wall portion 30 having the rail groove 38 at the lower end portion and the upper end portion. The adhesive is injected into the rail groove 38 at the lower end portion so that the adhesive is dried so that the bottom plate 10 and the side wall portion 30 can be adhered to each other while the side wall portion 30 surrounds the bottom plate 10. [ It is necessary to restrain the side wall portion 30 from being detached from the bottom plate 10 until the side wall portion 30 is removed. Any conventional clamp or fixture can be used to restrain the side wall portion 30 and any tool that can push the side wall portion 30 toward the bottom plate 10 can be used.

Of course, if there is a portion of the circumference of the bottom plate 10 that is to be abruptly bent, such as a portion B and a portion C in FIG. 1, before the side wall 30 covers the periphery of the bottom plate 10, A step of performing a wedge-shaped cutting operation must be performed first on at least a part of the rail groove 38 of the rail 30.

If the adhesive is dried and the side wall part 30 is fixed in a state surrounding the bottom plate 10, the light emitting part 40 that emits light is installed in a space defined by the bottom plate 10 and the side wall part 30 (S300). However, the light emitting portion 40 may be first installed on the bottom plate 10, and then the side wall portion 30 may be fixed to the bottom plate 10.

The lid plate 20 is placed on the upper end of the side wall portion 30 by pressing the lid plate 20 with the downward pressure by placing the lid plate 20 at the upper end of the side wall portion 30 And then fixed in the rail groove 38 (S400). It is preferable that an adhesive is injected into the rail groove 38 located at the upper end of the side wall 30 so that the lid plate 20 can be firmly engaged with the side wall 30.

When the cover plate 20 is fitted into the rail groove 38 located at the upper end portion of the side wall portion 30, the cover plate 20 is deformed downward convexly, the side wall portion 30 is opened outwardly, When the plate 20 is completely inserted into the rail groove 38, the cover plate 20 is restored to its flat shape and the side wall portion 30 is returned to its original position again.

However, in the case where the longitudinal vertical cross-section of the cover plate 20 is rectangular, it may be difficult to fit the cover plate 20 into the rail groove 38. Also, in the case where the outer rail 34 is formed to have a length of L2 as in the case of the inner rail 36, it becomes more difficult to insert the cover plate 20 into the rail groove 38.

Therefore, it is preferable to further perform a step of sloping the side surface of the cover plate so that the area of the upper surface of the cover plate 20 is larger than the area of the lower surface. In this case, the side of the cover plate 20 is brought into sliding contact with the outer rail 34 by placing the cover plate 20 at the upper end of the side wall portion 30 and applying a downward pressure to the side wall portion 30 So that the cover plate 20 can be easily fitted into the rail groove 38. In addition to the side surface of the cover plate 20 being inclined, the outer rail 34 may be formed to protrude by a distance L1 shorter than the inner rail so that the friction of sliding the side surface of the cover plate 20 on the outer rail 34 is further reduced So that the cover plate 20 can be easily fitted into the rail groove 38. [

The bottom plate 10 may be inclined in the same manner as the cover plate 20. In this case, after the periphery of the cover plate 20 is fixed so as to surround the side wall portion 30, Since the illumination device according to the present invention can be assembled in a manner that the illumination device is coupled to the illumination device 30, the degree of freedom of assembly is increased.

In the case of the channel signboard according to the related art, the steel member or the like must be bent and bent in the form of a specific character or pattern. Therefore, in the production of the channel signboard, except for the light emitting portion 40, ), There is a problem that mass production is difficult.

However, in the case of the lighting device according to the present invention, since the side wall portion 30 can be produced by standardizing and the same side wall portion 30 is used for all characters or patterns, the present invention is suitable for mass production, This has a simple advantage. Further, there is no need to use bolts or the like, and in the case of the cover plate 20, the cover plate 20 can be pressed and inserted into the side wall portion 30, which is advantageous in that the manufacturing method is very simple.

It is apparent that the illumination device according to the present invention can be used as an interior decoration for a room or a display.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not to be limited to the details thereof and that various changes and modifications will be apparent to those skilled in the art. And various modifications and variations are possible within the scope of the appended claims.
