Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an installation frame for fixing a light-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an installation frame, and more particularly to an installation frame for fixing a luminescent panel used in a building signboard or a road sign.

In buildings and roads, signs and road signs are often installed for the purpose of providing advertisements or information.

Such a signboard or a road signboard can have various configurations and shapes. As shown in FIGS. 1 and 2,

A light emitting panel P which emits light, a light emitting panel P through which the emitted light passes, a rear light emitting diode P disposed behind the light emitting panel P, A reflective film R in the form of a film that re-enters the front of the light emitting panel P, a light emitting panel P disposed in front of the light emitting panel P to protect the light emitting panel P, A transparent sheet C (e.g., a diffusion sheet or a protective sheet) serving as a transparent material for switching the direction of the light emitted from the light emitting panel P, And an installation frame F for fixing and protecting the light emitting panel P by covering all the components.

The LED lamp L may be inserted into the end of the luminescent panel P or may be arranged to contact the end of the luminescent panel P after being fixed to the mounting frame F. [

In general, the molding portion M is formed along the rim of the luminescent panel P to prevent the LED lamp L from being separated from the luminescent panel P.

Therefore, even at night, information provided by signboards and road signs can be seen more clearly.

However, if the temperature of the LED lamp (L) itself increases, the lifetime of the LED lamp (L) is shortened and the luminous efficiency is lowered.

Therefore, it is important to fundamentally increase the effect of heat dissipation (heat) to prevent temperature increase of the LED lamp (L) itself.

In general, the light-emitting panel P is made of synthetic resin such as acrylic transparent resin.

Therefore, when heat is generated in the LED lamp (L), the luminescent panel (P) expands due to heat and shrinks again when heat is interrupted.

The luminescent panel P presses the LED lamp L when the luminescent panel P is expanded when the LED lamp L is fixed to the mounting frame F. When the luminescent panel P is fixed to the mounting frame F, The distance between the luminescent panel P and the LED lamp L is distant from each other and the illumination brightness of the LED lamp L is reduced.

Accordingly, the expansion or contraction of the luminescent panel P may cause the LED lamp L to break or degrade its performance.

In order to solve the above-mentioned problems, a technique relating to a mounting frame for fixing a luminescent panel is disclosed in, for example, Korean Patent Laid-Open Publication No. 10 (1999) -0047134 (hereinafter referred to as "prior art" Light guiding panel assembly "

In the prior art,

A light guide plate through which the diverged light passes, a standing plate disposed behind the light guide plate, a light diffusion panel disposed in front of the light guide plate, a transparent cover, and a frame surrounding the components.

At the end of the standing plate, a light receiving unit for receiving the LED lamp is formed, and the light receiving unit is formed in a 'B' shape protruding forward from the end of the standing plate.

A side surface of the light receiving portion is in close contact with a rim of the light guide plate, and a through hole is formed in a side surface of the light receiving portion contacting the light guide plate so that the light source passes through the light guide plate.

 At this time, the standing plate is made of a material which can expand and contract by the temperature change, and the light guide plate and the standing plate are fixed to each other by bolts.

A base plate made of an aluminum material is disposed between the light guide plate and the standing plate. The base plate is independently connected to the light guide plate and the standing plate.

At this time, the base plate serves as a reflector functioning to re-enter the forward light of the light-emitting panel.

According to the above configuration, when the light guide plate expands or shrinks due to heat, the upright plate coupled with the light guide plate simultaneously moves along the light guide plate.

Therefore, since the light receiving portion formed on the end portion of the standing plate also moves, it is possible to reduce a case where the LED lamp is broken or the performance is deteriorated.

The prior art described above allows the LED lamp to move along the light guide plate upon expansion or contraction of the light guide plate to reduce breakage and performance deterioration of the LED lamp. However, it is possible to calculate how much the light guide plate expands or shrinks It is necessary to manufacture an installation frame for covering the light guide plate, so that it may be difficult to manufacture the installation frame.

Also, if the electrically operated LED lamp is continuously repeated, the performance of the LED lamp will eventually be reduced.

Above all, the prior art does not have a function to dissipate heat generated from the LED lamp itself.

If the temperature of the LED lamp itself increases, the lifetime of the LED lamp is shortened and the luminous efficiency is lowered.

Therefore, it is important to fundamentally increase the heat radiation effect to prevent the temperature increase of the LED lamp itself.

In addition, in the prior art, a base plate made of a metal material which does not expand or shrink should be disposed behind the light guide plate in order to reduce the deformation of the light guide plate in the front-rear direction.

Therefore, it is impossible to diverge the light source behind the light guide plate, and information can not be provided in both directions as needed.

In view of the above problems, it is an object of the present invention to provide an installation frame for fixing an luminescent panel, which prevents the expansion or contraction of the luminescent panel by increasing the heat radiation function, .

It is another object of the present invention to provide an installation frame for fixing a luminescent panel which can provide information to front and rear sides of a luminescent panel as required.

According to a first aspect of the present invention, there is provided an installation frame for fixing a light emitting panel,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

First, referring to FIG. 3, an installation frame for fixing a light emitting panel according to a first embodiment of the present invention will be described.

As shown in FIG. 1, the mounting frame for fixing the luminescent panel according to the first embodiment of the present invention comprises a base 10, a fixed partition 20, and a coupling groove 30.

Looking at each configuration,

The base (10)

As shown in FIG. 3, the light emitting panel P is in contact with the edge of the light emitting panel P, and has a bar shape having a predetermined width and thickness.

At this time, the base 10 can be bent or bent according to the shape of the various light-emitting panels P as required (see FIG. 7).

An LED lamp L as a light source is disposed inside the rim of the luminescent panel P and an adhesive or the like is applied to the rim of the luminescent panel P so that the LED lamp L is firmly coupled to the luminescent panel P. A molded part M constituted is formed.

The base 10 is made of aluminum, which is a metal.

When the base 10 is made of a synthetic resin material, the temperature of the LED lamp L is increased because heat generated from the LED lamp L is not smoothly conducted to the base 10 serving as a heat sink .

If the generated heat is not released and the temperature of the LED lamp L is increased, the lifetime of the LED lamp L is shortened and the luminous efficiency is lowered.

When the base 10 functioning as a heat sink is made of aluminum having a high thermal conductivity, the LED lamp L can be easily dissipated, shortening the life of the LED lamp L and reducing the luminous efficiency prevent.

Therefore, the base 10 is preferably made of aluminum.

Inside the base 10, a cooling chamber 11 is formed along the longitudinal direction of the base 10 to guide the flow of air.

In the base 10, a communication hole 12 for connecting the upper side of the base 10 and the cooling chamber 11 is formed.

Here, the 'upper side' designates the surface of the base 10 to be in contact with the luminescent panel P.

At least one or more communication holes 12 are formed along the longitudinal direction of the base 10.

An exhaust hole 13 is formed in the base 10 to connect the cooling chamber 11 to the outside.

Here, 'outside' refers to the opposite side on which the luminescent panels P are arranged with respect to the base 10.

At least one exhaust hole 13 is formed along the longitudinal direction of the base 10.

The operation of the mounting frame for fixing the luminescent panel according to the first embodiment of the present invention having the above-

When the LED lamp L emits light and generates heat, the heat is transferred to the communication hole 12 to start the heat radiation.

The heat transferred to the communication hole (12) passes through the communication hole (12) and is transferred to the cooling chamber (11).

The heat transferred to the cooling chamber (11) is circulated along the cooling chamber (11) by the flow of air, and then is discharged to the outside through the exhaust hole (13).

Accordingly, the heat emitted from the LED lamp L is discharged to the outside to dissipate heat.

In addition, as described above, heat radiation starts inside the base 10, and cooling of the LED lamp L starts outside the base 10.

The outside air passes through the exhaust hole (13) and enters the cooling chamber (11).

The outside air entering the cooling chamber 11 is circulated along the cooling chamber 11 by the flow of air and passes through the communication hole 12 to be in contact with the LED lamp L. [

Therefore, the LED lamp (L) is cooled by the outside air.

Also, a part of the heat generated in the LED lamp L is conducted to the body of the base 10 so that heat is dissipated separately.

The heat conducted to the main body is transferred to the cooling chamber 11 and circulated along the cooling chamber 11 and then discharged through the exhaust hole 13 to the outside or directly to the outside through the base 10 .

Due to the construction of the cooling chamber 11, the communication hole 12 and the exhaust hole 13 as described above, the heat radiation function of the installation frame F for fixing the luminescent panel of the present invention is increased.

Therefore, since the above-described configuration prevents an increase in the temperature of the LED lamp L, there is an effect of preventing a shortening of the life of the LED lamp L and a decrease in luminous efficiency.

The fixed barrier rib (20)

As shown in FIG. 3, protrusions are formed on both side ends of the base 20 and are formed along the longitudinal direction of the base 10.

At this time, each of the fixed barrier ribs 20 may be formed to be slightly bent toward the upper center of the base 10 so as to more firmly surround the luminescent panel P when the luminescent panel P is coupled.

The coupling groove 30 is formed,

As shown in FIG. 3, the upper surface of the base 10 is formed in an inner space formed by the fixed barrier ribs 20, and the rim of the luminescent panel P is inserted and fixed.

At the center of the bottom surface of the coupling groove 30, an air guide groove 31 is formed downward along the longitudinal direction of the coupling groove 30.

The heat emitted from the LED lamp L travels along the air guide groove 31 and then passes through the communication hole 12 to move to the cooling chamber 11 or vice versa, Flows through the communication hole 12 and circulates along the air guide groove 31 to cool the LED lamp L. [

Therefore, the heat radiating function of the present invention is further increased due to the air guide groove 31, thereby reducing the lifetime of the LED lamp L and the deterioration of the luminous efficiency.

Hereinafter, an installation frame for fixing a luminescent panel according to a second embodiment of the present invention will be described with reference to FIG. 5A.

As shown in the drawing, the mounting frame for fixing the luminescent panel according to the second embodiment of the present invention comprises a base 10, a fixed partition 20, and a coupling groove 30.

Looking at each configuration,

The base (10)

As shown in FIG. 5A, the light emitting panel P is in contact with the edge of the light emitting panel P, and has a bar shape having a predetermined width and thickness.

At this time, the base 10 may be bent or bent according to the shape of the various luminescent panels P as required (see FIG. 7).

An LED lamp L as a light source is disposed inside the rim of the luminescent panel P and an adhesive or the like is applied to the rim of the luminescent panel P so that the LED lamp L is firmly coupled to the luminescent panel P. A molded part M constituted is formed.

The base 10 is made of aluminum, which is a metal.

The reason why the base 10 is made of aluminum is the same as that of the first embodiment described above, and a duplicate description will be omitted.

Inside the base 10, a cooling chamber 11 is formed along the longitudinal direction of the base 10 to guide the flow of air.

In the base 10, a communication hole 12 for connecting the upper side of the base 10 and the cooling chamber 11 is formed.

Here, the 'upper side' designates the surface of the base 10 to be in contact with the luminescent panel P.

At least one or more communication holes 12 are formed along the longitudinal direction of the base 10.

An exhaust hole 13 is formed in the base 10 to connect the cooling chamber 11 to the outside.

Here, 'outside' refers to the opposite side on which the luminescent panels P are arranged with respect to the base 10.

At least one exhaust hole 13 is formed along the longitudinal direction of the base 10.

The operation of the mounting frame for fixing the luminescent panel according to the second embodiment of the present invention having the above-

When the LED lamp L emits light and generates heat, the heat is transferred to the communication hole 12 to start the heat radiation.

The heat transferred to the communication hole (12) passes through the communication hole (12) and is transferred to the cooling chamber (11).

The heat transferred to the cooling chamber (11) is circulated along the cooling chamber (11) by the flow of air, and then is discharged to the outside through the exhaust hole (13).

Accordingly, the heat emitted from the LED lamp L is discharged to the outside to dissipate heat.

In addition, as described above, heat radiation starts inside the base 10, and cooling starts from the outside of the base 10.

The outside air passes through the exhaust hole (13) and enters the cooling chamber (11).

The outside air entering the cooling chamber 11 is circulated along the cooling chamber 11 by the flow of air and passes through the communication hole 12 to be in contact with the LED lamp L. [

Therefore, the LED lamp (L) is cooled by the outside air.

Also, a part of the heat generated in the LED lamp L is conducted to the body of the base 10 so that heat is dissipated separately.

The heat conducted to the main body is transferred to the cooling chamber 11 and then circulated along the cooling chamber 11 and then discharged through the exhaust hole 13 to the outside or directly to the outside through the base 10 .

Due to the construction of the cooling chamber 11, the communication hole 12 and the exhaust hole 13 as described above, the heat radiation function of the installation frame F for fixing the luminescent panel of the present invention is increased.

Therefore, since the above-described configuration prevents an increase in the temperature of the LED lamp L, there is an effect of preventing a shortening of the life of the LED lamp L and a decrease in luminous efficiency.

The fixed barrier rib (20)

As shown in FIG. 5A, three or more protrusions are formed on the upper portion of the base 10 at regular intervals, and are formed along the longitudinal direction of the base 10.

The coupling groove 30 is formed,

As shown in FIG. 5A, the luminescent panel P is formed in an inner space between adjacent fixed barrier ribs 20, and the rim of the luminescent panel P is inserted and fixed.

At this time, due to the above-mentioned three or more fixed partition walls 20, a plurality of coupling grooves 30 are formed.

At the center of the bottom surface of the coupling groove 30, an air guide groove 31 is formed downward along the longitudinal direction of the coupling groove 30.

The heat emitted from the LED lamp L travels along the air guide groove 31 and then passes through the communication hole 12 to move to the cooling chamber 11 or vice versa, Flows through the communication hole 12 and circulates along the air guide groove 31 to cool the LED lamp L. [

Therefore, the heat radiating function of the present invention is further increased by the air guide groove 31.

A reflection plate R in the form of a film for preventing the light emitted from the LED lamp L from being lost to the rear and re-entering the light to the front of the luminescent panel P is disposed behind the luminescent panel P .

Therefore, information can be provided only forward.

However, according to the present invention, it is possible to arrange the reflector R of each of the light emitting panels P so as to face each other due to a structure formed by a plurality of coupling grooves 30 capable of simultaneously inserting and fixing a plurality of light emitting panels P Therefore, there is an effect that information can be provided to both front and rear sides.

5B, in the second embodiment of the present invention, the light-emitting panel P is inserted only into one coupling groove 30 of the plurality of coupling grooves 30, and the other coupling groove 30, the light-emitting panel P can be non-inserted.

At this time, the finish cover C1 is coupled to the outside of the coupling groove 30 in which the luminescent panel P is not inserted, using a bolt or the like.

The air introduced through the exhaust hole 13 circulates through the cooling chamber 11 and is then transferred to the internal space D through the communication hole 12. [

Therefore, since the air moved to the inner space D cools the luminescent panel P, the heat radiation effect of the luminescent panel P is further increased.

Hereinafter, an installation frame for fixing a luminescent panel according to a third embodiment of the present invention will be described with reference to FIG.

As shown in the drawing, the mounting frame for fixing the luminescent panel according to the third embodiment of the present invention comprises a base 10, a fixed partition 20, and a coupling groove 30.
