Description

{LED Lighting Fixture}

The present invention relates to an LED lighting device installed on a ceiling or a wall surface to provide illumination to the inside or outside of a room, and more particularly to an LED lighting device with improved light efficiency and uniformity of light.

In general, indoor lighting includes a living room, a lamp, a kitchen, and a toilet, and these use incandescent lamps and fluorescent lamps. Fluorescent lamps are also commonly used as light sources for lighting signage.

Currently, various types of fluorescent lamps, three-wavelength lamps, and LED lights are installed in various forms from incandescent lamps using filaments, and the lighting industry is continuously developing.

Meanwhile, compared with the above-described three-wavelength lamp, the light emitting diode (LED), which is a next generation light source that can be used semi-permanently and has excellent energy saving effect compared to the existing light source, is firmly established in the lighting industry.

As the luminance (brightness) problem, which was the limit of the illumination using the LED, has recently been greatly improved, the application market has spread to the entire industry and the full-scale LED is being applied.

These LEDs have excellent characteristics such as low power consumption, which is an element that forms electrode terminals on both sides of p-type and n-type junctions, and when a voltage is applied between the terminals, the current flows and the light is emitted near the pn junction. Has been developed. It is classified into an edge type and a direct type according to the layout of the LED. In the edge type, LEDs are disposed only on the side surface of the panel, and direct-type LEDs are disposed on the entire panel. In particular, in the case of the edge type, it is expected that the structure of the edge type rather than the direct type is expected to become popular because the thickness of the panel can be further reduced and the power consumption is also small.

However, these LED lights have limitations in reducing the overall appearance thickness. In addition, since the lifetime of the LED is equivalent to about 50,000,000 hours, components of a converter such as a capacitor, for example, a capacitor that converts power to an LED, have a much shorter lifetime than an LED, .

In addition, it is difficult to attach and detach the LED light from the ceiling or the wall surface, which increases the working time and increases the costs.

Further, the illumination module 110 may be implemented as a direct type or an edge type that provides light as a light source using the LED element 114, and more preferably an edge type. Therefore, since the lighting module 110 is formed as an edge type, its thickness is thin, maintenance is easy, and economical efficiency can be obtained.

The outer frame 120 is disposed at an edge portion of the lighting module 110 as an injection or extrusion molded frame made of a steel material. Since the corner of the lighting module 110 is partially inserted into the coupling groove 121 of the outer frame 120, the assembly process of the lighting module 110 is not necessary, There is an effect that can be lowered. The outer frame 120 includes a first frame 120a disposed at one side edge of the lighting module 110 and a second frame 120b disposed at the other side edge adjacent to the one side edge.

The fastening hole 131a is formed in the corner bracket 130, A separate cap for shielding the upper portion of the fastening hole 131a on the upper surface support portion 131 may be coupled. Thereby, since the fastening hole 131a is not visible, the appearance can be formed more beautifully.

A distance corresponding to at least the height of the lighting module 110 is formed between the upper surface support portion 131 and the lower surface support portion 132.

An auxiliary support portion 136 for supporting the lower surface of the vertex portion of the illumination module 110 is provided on the upper surface of the support portion 132. The support portion 132 integrally extends to the inside of the lower support portion 132, And a wire connecting hole 138 is formed to connect a wire W connecting between the ceiling and the ceiling.

The auxiliary supporting portion 136 is bent at an angle corresponding to the angle of the vertex portion of the lighting module 110 and protruded from the upper surface of the lower supporting portion 132. Therefore, a gap corresponding to the height of the lighting module 110 is formed between the lower surface of the upper surface support portion 131 and the upper surface of the auxiliary support portion 136.

When one end of the first frame 120a and one end of the second frame 120b are coupled to the corner bracket 130, the first frame 120a and the second frame 120b A passage through which wiring can pass is formed. In addition, the heat generated in the lighting module 110 can be discharged to the outside since the heat dissipation hole 135 formed on the lower support portion 132 is positioned on the passage.

The first frame 120a and the second frame 120b are fastened by the fastener on the lower supporting part 132 and the first frame 120a or the second frame 120b is fastened on the lower supporting part 132. [ A plurality of fastening holes 134 are formed so that fasteners to be connected can be inserted.

And a third hook 443 protruding in parallel with the second hook 443. The outer frame shielding member 441 has a second hook 442 coupled to the first fixing protrusion 329a in a direction perpendicular to the upper surface of the outer frame 320 and a third hook 442 coupled to the second fixing protrusion 329b, The hook 443 is engaged and the outer frame member 441 and the outer frame 320 are coupled.

The corner shielding member 445 includes a fourth hook 446 protruding downward to be inserted into a fastening hole 331a formed on the upper surface support portion 331 of the corner bracket 330. [

Accordingly, the outer shielding member 441 and the corner shielding member 445 can be separated and joined or detached.

When the outer shielding member 441 and the corner shielding member 445 are separately manufactured, the manufacturing cost is reduced and the size is easily adjusted. In addition, the outer shield 431 and the corner shield 445 can be selectively applied with different colors or designs.

FIG. 17 is a partial cross-sectional perspective view showing a state in which the shielding portion of the LED lighting apparatus according to the fifth embodiment of the present invention is rotated and opened, and FIG. 18 is a sectional view partially showing the LED lighting apparatus shown in FIG.

17 and 18, the LED lighting apparatus 500 according to the fifth embodiment of the present invention has a coupling protrusion 534 protruded from the upper surface of the side supporting portion 533 of the corner bracket 530. In addition, a coupling protrusion (not shown) having the same shape as that of the coupling protrusion is protruded from the upper surface of the side support portion of another corner bracket adjacent to the corner bracket 530.

The outer frame 520 is coupled between the corner bracket 530 and another corner bracket adjacent to the corner bracket 530, and the shielding portion 540 is rotatably coupled between the engaging projections 534 facing each other.

The outer shielding member 541 includes a coupling piece 544 detachably coupled to the coupling protrusion 534 and a bottom surface of the outer shielding member 541 connected to the upper surface member 522 of the outer frame 520. [ And a fifth hook 545 coupled to the first fixing step 529a to prevent the outer shielding member 541 from being opened when the upper part is coupled.

The engagement of the engagement piece 544 and the engagement protrusion 534 may be formed by a one end face of the engagement piece 544 being formed in a C shape and being coupled in an interference fit manner or by pressing the outline shielding member 541 The engaging pieces 544 and the engaging protrusions 534 may be elastically engaged with each other in a state where a bending deformation is generated. Of course, the fastening pieces 544 may be inserted into the coupling protrusions 534 at one side and coupled at the other side in an interference fit manner.

At this time, when the outer shielding member 541 is closed, the outer shielding member 541 is closely contacted with the corner shielding member 445 to provide an unified sense of appearance, and rounds of the same size are formed to provide a smooth curved feel. In addition, a part of the side member 523 may be exposed to the outside under the outer cover member 541.
