Description

[0001] The present invention relates to a ceiling finishing type LED lighting apparatus,

The present invention relates to a ceiling-mounted LED lighting device for lighting a ceiling of an indoor space of a building and emitting light toward an indoor space of a building.

There are various structures such as electric wiring, ducts, cable trays, and internet connection lines in the ceiling of the interior space of the building, which deteriorates the aesthetics and accelerates the neutralization of the exposed concrete. Especially, due to the neutralization of the concrete, the life of the concrete is shortened, and various dusts and various structures are dropped from the ceiling of the indoor space and various safety accidents have occurred. Accordingly, various types of ceiling materials are installed in an indoor space of a general concrete building to improve aesthetics and safety.

Most of the ceilings were constructed by arranging a plurality of panels in a ceiling scene of an indoor space and screwing a plurality of panels and a ceiling scene together. However, when a plurality of panels are screwed to a ceiling surface as in the prior art, there is a problem that the screws exposed to the outside are corroded and the appearance of the interior space is poor. In addition, due to such screw corrosion, debris is generated and falls, or the connection between the panel and the ceiling is weakened, so that the panel is separated from the ceiling and falls down frequently.

Korean Patent No. 10-1063630 discloses a fixing device comprising a first prime member, a fixing portion including a first fixing member and a second fixing member, a connecting portion, and a ceiling panel, And a ceiling finishing apparatus for installing a ceiling scene by joining a ceiling panel to the government. In the prior art including the above-mentioned patents, a plurality of members having different sizes and shapes are required, so that the construction process of joining the members and the members is combined, and the shrinkage of the ceiling material There is a problem in that a plurality of ceiling materials are out of alignment with each other or separated from a ceiling surface because of the inability to accommodate the expansion.

On the other hand, the conventional indoor lighting device has mainly used a fluorescent lamp and an incandescent lamp as a light source, but has a problem of a large power consumption and a short life span as compared with brightness. Accordingly, in recent years, an outdoor lighting device using an LED (Light Emitting Diode) as a light source has become popular. LEDs have much lower power consumption and longer life than fluorescent or incandescent lamps. However, since the light emitted from the LED light source has a property of going straight, shading occurs in the interior of the building. In addition, there is a problem that the illuminance difference between the illuminated area of the LED and the other area is very large, and the illuminance of the interior of the building is not uniform.

Most conventional LED lighting devices solve this problem by covering a printed circuit board on which a large number of LEDs are integrated with a cover having a function of diffusing the light of the LED. However, in this conventional method, since light emitted from the LED is refracted in the process of passing through the cover, light diffusion of the LED is attempted, so that there is still a large area of shade in the inside of the building, It may be uniform around the device, but it is not uniform in most areas.

Korean Patent Registration No. 10-1273627 discloses a technique in which light emitted from an LED is firstly diffused through an internal light diffusion member and then light is emitted to the outside through a light projection cap to increase a light diffusion angle, A fluorescent lamp type illumination device is provided. Korean Patent No. 10-1586400 discloses an LED lighting device provided with a side reflecting member capable of removing side shadow generated at an inner wall edge of an LED lighting device. However, such conventional arts also have a limitation in allowing the light of the LED to be diffused throughout the building as the LED illumination device is installed at a local site such as the center of the ceiling of the building.

Major causes of failure of the LED lighting device include overcurrent flow into the LED, overheating of the LED, and damage of the electronic device in the circuit supplying power to the LED. Generally, an LED illumination device is manufactured by densely mounting many LED chips of a very small size on a printed circuit board for preventing overheating, and installing heat dissipating means for emitting heat of the LED chips. There is a problem in that some of the plurality of LEDs densely mounted on the printed circuit board have an abnormality, so that the temperature of the surrounding LEDs also rises together with failure.

And an object of the present invention is to provide a ceiling-close type LED lighting apparatus which can solve the problems of conventional ceiling finishing methods such as corrosion of screws with a very simple structure and solve the problems of conventional LED lighting apparatuses such as unevenness of the interior space of a building. The present invention is not limited to the above-described technical problems, and another technical problem can be derived from the following description.

It is possible to prevent the debris generated due to screw corrosion from falling into the indoor space and also to prevent the detachment of the square panel from the ceiling scene due to the weakening of the screwing force due to the screw coring and the aesthetics of the indoor space can be further improved .

In addition, each band is inserted from the outside into a gap between two square panels disposed at the edges of two adjacent square panels, and then inserted into the gap between the remaining square panels of the adjacent two rows in turn By covering the connection clip between the square panels of two rows adjacent to each other as a load, the connection clip can cover the whole ceiling panel with the square panel, and then the band can be inserted and finished in every gap between adjacent square panels The workability of the ceiling finish can be greatly improved.

In addition, each connecting clip is made of a steel sheet material having a thickness thinner than the width of the groove of each square panel, and a part of the connecting clip is bent so that two concave portions The two rectangular panels can be connected by a lightweight structure having a high strength. As a result, deformation of the two joints of the connection clip due to the weight of the square panel and the connection clip can be prevented, and separation of the connection clip and the rectangular panel can be prevented.

Each of the connecting clips is formed in the shape of a flat plate having at least one screw hole at the center, and the bottom plate fixed to the ceiling of the indoor space of the building by screwing and the two side portions of at least one screw hole of the bottom plate And two symmetrical cross-sectional areas between the bottom plate and the two wings are formed in the cross-section of the two square panel grooves By forming the two joints simultaneously stuck on the lower jaw, a connection clip of high strength and light weight structure can be provided and the weight of the two square panels can be supported in a balanced manner.

In addition, the two square panels bonded by each connecting clip are spaced apart by the distance between the two wings of each connecting clip, and each band made of a flexible material has a wider width than the spaced distance of the two square panels So that all the connection clips, screws, and concrete between the two square panels are covered, and at the same time, the square panels are not separated or twisted even when they are expanded or contracted according to the humidity of the room space.

Each band-shaped LED can be implemented with a very simple structure in which a plurality of LEDs are mounted on a conductive film on an insulation band, which is a band-shaped insulation having a width wider than the distance between the two rectangular panels, Since the device can be realized with a very simple structure that sandwiches the band-type LEDs between the rectangular panels installed on the ceiling of the building, the housing, the heat dissipating means, etc. of the conventional LED lighting device are not required, The problem of the ceiling finishing method of the conventional LED lighting apparatus can be solved and at the same time the problem of the conventional LED lighting apparatus can be solved.

In addition, it is possible to prevent the neutralization of the concrete from being accelerated by covering a part of the exposed concrete with the band-type LEDs 30. In addition, the aesthetics of the interior space can be further improved as the connection clip 20, the screws 270, and the concrete are not exposed to the outside.

Referring to FIG. 5, a band-shaped LED 30 is sandwiched between two rows of adjacent rectangular panels 10. As shown in Fig. 1, a " C "-shaped groove 11 is formed on two opposite side surfaces of the four side surfaces, and a plurality of square panels 10 having the other two side surfaces are arranged in a line So that the row of the rectangular panel 10 is formed. Shaped grooves 11 are formed on both sides of the row of the rectangular panel 10 along the row direction of the rectangular panel 10 and the band type LEDs 30 Is inserted.

As described above, the band-shaped LED 30 has a "?" -Shaped groove (not shown) extending long between the square panels 10 of two adjacent rows of square panels 10 among the rows of the plurality of square panels 10 11 so as to cover and cover all the connecting clips 20 between the square panels 10 adjacent to each other to emit light toward the interior space of the building. Accordingly, the band-shaped LED 30 should be made longer than the length of the row of the rectangular panel 10. FIG. 5 shows the process of inserting the band-shaped LEDs 30 between adjacent rectangular panels 10.

5 (a), the band-shaped LED 30 has a gap between the inner surfaces of the grooves 11 of the two rectangular panels 10 arranged at the edges of the square panels 10 adjacent to each other in two rows, I.e., from the lower space of the two rectangular panels 10, in the longitudinal direction. Subsequently, as shown in FIG. 4 (b), the two rectangular panels 10 adjacent to each other are sandwiched by gaps between the remaining square panels 10 of the two rows adjacent to each other in turn, And covers all the connecting clip 20 between them to emit light towards the interior space of the building.

As described above, the band-shaped LED 30 is made of a flexible material so that the band-shaped LED 30 is bent from the outside into a gap between two rectangular panels 10 disposed at the edges of two adjacent rectangular panels 10, . Since the plurality of rectangular panels 10 are constructed so as to cover the entire ceiling surface 40, if the band-like LED 30 is not made of a flexible material, the two square panels 10 arranged at the edge of the ceiling surface 40, It can not be inserted through the gap between the inner surfaces of the grooves 11 of the base plate 11. According to the present embodiment, after the entire ceiling panel 40 is covered with the rectangular panel 10 using the connecting clip 20, the band-like LEDs 30 are inserted into the spaces between the adjacent rectangular panels 10 The finishability of the ceiling finish can be greatly improved because it can be finished.

4, one side of each of the band-type LEDs 30 is fitted in the groove 11 of one of the two rectangular panels 10 adjacent to each other, and the band-like LEDs 30 Is sandwiched in the groove 11 of the other one of the two square panels 10 adjacent to each other so that each of the band-shaped LEDs 30 is divided into two rectangular panels 10, Should be formed to have a wider width than the distance that is formed. If the band-shaped LED 30 has a narrower width than the distance between the two rectangular panels 10, the band-shaped LED 30 is formed in the groove 11 of the adjacent two rectangular panels 10 So that it can not be inserted. Thus, it should be noted that the band-like LEDs 30 have a wider width than the distance between the two rectangular panels 10.

In order to insert the band-shaped LED 30 into the " C "-shaped groove 11 on the side surface of the square panel 10, the connecting clip 20 is formed in a" Should be formed to have a thickness smaller than the width of the substrate 11. 6-7, the wings 23 of the connecting clip 20 and the band-shaped LED 30 are inserted into the groove 11 of "C" shape. If the connecting clip 20 has a thickness that is thicker than the width of the " C "-shaped groove 11, the engaging portion 25 of the connecting clip 20 is engaged with the" 11), so that it is difficult to connect the connecting clip 20 and the rectangular panel 10 together. When the thickness of the connection clip 20 becomes similar to the width of the " C "-shaped groove 11 of the rectangular panel 10, the band-shaped LED 11 30 are insufficient, it is difficult to insert the band-shaped LED 30 between adjacent rectangular panels 10. Accordingly, the connection clip 20 should be formed to have a thickness smaller than the width of the " C "shaped groove 11 on the side surface of the rectangular panel 10. [

7, a band-shaped LED 30 is positioned between two rectangular panels 10 adjacent to each other, and a band-shaped LED 30 is disposed between the connecting clip 20 and a rectangular panel The concrete between the first and second plates 10 is obscured. By covering the connection clip 20 and the screw with the band-type LED 30, corrosion or oxidation of the screw is prevented so that the debris of corrosion falls into the interior space or the fixing force of the square panel 10 to the ceiling surface 40 The problem that the rectangular panel 10 is detached from the ceiling scene 40 can be solved. In addition, the band-shaped LED 30 covers a part of the concrete exposed to the outside, so that the neutralization of the concrete is not accelerated and the life of the concrete structure is prevented from being drastically deteriorated.

On the other hand, the rectangular panel 10 repeatedly shrinks and expands according to the humidity of the indoor space. When a plurality of panels are closely contacted without being spaced apart by a predetermined distance, the panel is expanded or contracted due to humidity, so that a plurality of panels fixed to the ceiling surface 40 are separated or twisted. Meanwhile, the rectangular panel 10 according to the present embodiment is spaced apart from each other by the distance between the two wings 23 of the connection clip 20, and between the adjacent two rectangular panels 10, As a result, the problem that the rectangular panel 10 is separated or twisted does not occur even if the rectangular panel 10 is expanded or contracted according to the humidity of the indoor space.

As described above, a plurality of rectangular panels 10 having a cross-section "C" -shaped groove 11 on at least one side of the four sides, a plurality of rectangular panels 10, A plurality of connecting clips 20 having two engaging portions 25 to be simultaneously stitched and a plurality of connecting clips 20 made of a flexible material and fitted longitudinally in the gap between the inner surfaces of the grooves 11 of the two rectangular panels 10, 6, the ceiling-mounted LED lighting device is composed of a plurality of band-shaped LEDs 30 covering the connection clip 20 between the square panels 10. The ceiling-mounted LED lighting device is mounted on the ceiling, Safety can be improved. The ceiling construction is completed by molding between the edge of the ceiling 40 and the square panel 10 disposed along the edge of the ceiling 40 on the edge of the ceiling 40 of the indoor space.

 6, the band-shaped LED 30 covers the screw 270 coupled with the ceiling surface 40 through the screw hole 27 of the connection clip 20, and at the same time, The LEDs 33 emit light toward the indoor space of the building by the row of LEDs 33 exposed between the square panels 10 of the rows. Since the plurality of square panels 10 are arranged in a plurality of rows in the ceiling scene 40 so as to cover the entire ceiling scene 40 of the indoor space of the building, Are uniformly arranged at even intervals throughout the scene (40). As a result, the band-shaped LEDs 30 sandwiched between the rectangular panels 10 in two rows adjacent to each other are uniformly arranged at equal intervals throughout the ceiling surface 40.

The conventional LED lighting device is installed at a local site such as a center of a ceiling of a building, so that there is a limitation in allowing the light of the LED to spread throughout the building. The ceiling-mounted LED lighting apparatus according to the present embodiment is installed between two adjacent square panels 10 uniformly arranged at regular intervals over the entire ceiling 40, The shade of the interior of the building can be minimized as compared with the conventional LED lighting device because the light of the row of LEDs of the band-shaped LED 30 uniformly arranged at equal intervals is irradiated to the inside of the building, The illuminance of the light guide plate can be made more uniform as a whole.

In addition, according to the present embodiment, not only the band-like LEDs 30 are uniformly arranged at equal intervals over the ceiling surface 40, but also the LEDs in a row of the band-shaped LEDs 30 are arranged in a spaced- So that the heat generation of the LEDs due to the mounting of a large number of LEDs on the printed circuit board having a small area is not generated and the overheating phenomenon of the LEDs can be reduced and the heat of certain LEDs is prevented from being transmitted to the peripheral LEDs, It is possible to prevent the surrounding LEDs from failing together.

Examples of such insulating materials include polyethylene, synthetic rubber and the like. The conductive film 32 is formed in the form of a conductive pattern for connecting a plurality of LEDs 33 in parallel, in series, or in series and in parallel, and is laminated on one surface of the insulating band 31. The conductive film 32 may be made of a copper foil and oxidized when exposed to air. The plurality of LEDs 33 are mounted on the conductive film 32 so that their respective light emitting surfaces face the interior space of the building, and are supplied with power for their respective light emission from the conductive film 32. The coating film 34 is coated on one entire surface of the insulating band in which the conductive film 32 is stacked to prevent the oxidation of the conductive film 32. [

According to the embodiment shown in FIG. 8 (c), the conductive film 32 is formed in the form of two strips and laminated on one surface of the insulating band 31. The plurality of LEDs 33 are mounted on the conductive film 32 in a strip form on the two lines from the conductive film 32 in a line so that their respective light emitting surfaces face the interior space of the building. The spacing between the LEDs 33 in a row is determined according to the brightness of each LED, the size of the indoor space of the building, and the target illuminance of the interior of the building.

As shown in FIG. 8 (a), two strips of conductive film 32 may be connected to a wire, and a power supply (not shown) such as a Switching Mode Power Supply (SMPS) And a plurality of LEDs 33 can receive power from the conductive film 32 for each light emission.

When all of the LEDs 33 mounted on the conductive film 32 are connected in parallel, the power supply device supplies a high current value which is increased in proportion to the number of the LEDs 33 and an operation voltage of each LED 33 The corresponding low voltage power should be outputted. When the length of the band-type LED 30 is long, it may be difficult to manufacture a power supply device suitable for the band-shaped LED 30. In this case, the conductive film 32 may be formed in the form of a conductive pattern connecting a plurality of LEDs 33 in series, or may be formed by serially connecting a plurality of LEDs 33 in a predetermined number of groups, And may be formed in the form of a conductive pattern.
