Referring to FIGS. 1 to 6, a lighting stand apparatus 100 according to an embodiment of the present invention includes a support beam 200, an LED illumination unit 300, and a channel 400.

In particular, the lighting stand apparatus 100 according to the present invention is installed on a panel 10 provided on a table of a bookstore or work bench.

The support beam 200 is fixedly mounted on the panel 10 while being erected. In particular, the supporting beam 200 is provided to be coupled to both sides of the LED illumination unit 300 so as to be fixed to the panel 10. Of course, the support beam 200 may be applied in various shapes and materials. The support beam 200 can be fixedly mounted to the panel 10 in various ways. The position of the support beam 200 on the panel 10 is not limited.

In addition, the support beam 200 may form a wire inlet 210 on the lower circumferential surface for guiding the wire.

In addition, the LED illumination unit 300 is installed at a predetermined clearance from the panel 10 by being connected to both sides of the neighboring support beam 200.

The LED illumination unit 300 includes a light emitting module 310 that emits light by a light emitting device such as an LED.

In addition, the channel 400 is formed along the axial direction in the support beam 200, and serves to allow wiring to supply power to the LED illumination unit 300. Thus, the channel 400 refers to a wiring passage formed along the support beam 200.

In particular, the support beam 200 may be surrounded by a duct 410 along the axial direction to form the channel 400. At this time, the duct 410 can be deformed into various shapes and can be simply fitted on the circumferential surface of the support beam 200, so that maintenance and wiring work of the wiring can be facilitated. The wiring inlet 210 may be formed in the duct 410.

Meanwhile, the LED illumination unit 300 includes a bracket 320, a heat sink 330, and a coupling portion 340.

The bracket 320 includes a light emitting module 310 having a light emitting element such as an LED element, and is made of a metal material so as to have thermal conductivity, heat dissipation, and durability. Of course, the bracket 320 can be deformed into various shapes.

The bracket 320 forms guide hole portions 326 on both sides along the axial direction for wiring. At this time, the LED illumination unit 300 and the support beam 200 are connected and assembled so that the guide hole portion 326 is connected to the channel 400.

The heat sink 330 is connected to the bracket 320 and is made of a metal material to absorb heat generated from the light emitting module 310 and dissipate heat to prevent the bracket 320 from bending downward do. That is, the heat sink 330 serves to dissipate heat and support the bracket 320. Thus, the heat sink 330 is made of a metal material.

In addition, the heat sink 330 may have a plurality of slits 332 formed on the circumferential surface thereof in order to increase heat dissipation. Of course, the slit 332 can be deformed into various shapes.

Both sides of the heat sink 330 are assembled so as to be detachable from the support beam 200.

By way of example, the heat sink 330 inserts a portion of the binding angle 334 on each side. The corresponding support beam 200 then inserts the remainder of the binding angle 334 upward. Thereafter, the fastening member 336 fastens the heat sink 330 and the fastening angle 334, and fastens the fastening angle 200 and the fastening angle 334 together. Of course, the binding angle 334 can be modified into various shapes and various materials, and the fastening member 336 can be applied to various types such as bolts and screws.

The engaging portion 340 serves to slide and guide the bracket 320 to the heat sink 330.

On the other hand, the bracket 320 includes a frame 321, a rib 322, a supporter 323, and a cover 324.

The frame 321 is axially slidably coupled to the heat sink 330 to assemble the LED illumination unit 300 to the heat sink 330.

At this time, the frame 321 can be applied in various materials, but it is formed as a convex arc in the upward direction. It is assumed that the upper side of the frame 321 is assembled to the heat sink 330 and the rib 322, the supporter 323 and the cover 324 are provided on the lower side.

A plurality of ribs 322 extend on one side along the axial direction in the frame 321. Particularly, the ribs 322 are formed so as to protrude downward from the frame 321, and are arranged in parallel to each other along the axial direction of the frame 321. Thus, the rib 322 allows the smooth flow of the outside air from the inside (lower side) of the frame 321, thereby improving the heat radiation performance and serves as a guide for wiring. Of course, the number and shape of the ribs 322 are not limited.

The supporter 323 is formed at an end of each of the ribs 322 to slide the light emitting module 310.

In particular, the supporter 323 may be formed in a flat plate shape to stably support the light emitting module 310 and may include an assembly groove portion (not shown) formed on both sides along the axial direction so that the printed circuit board of the light emitting module 310 can be inserted. 327 may be formed.

Of course, the supporter 323 can be modified into various shapes.

At this time, both sides of the frame 321 are opened along the axial direction for ease of manufacturing. Then, the frame 321 is detachably assembled with the finishing cap 325 so as to block both sides that are open. Closure cap 325 is applicable in a variety of shapes and materials.

Particularly, the finishing cap 325 penetrates through the guide hole portion 326 so that it can be wired to the light emitting module 310 fitted into the supporter 323.

Of course, in the case of a housing shape in which the frame 321 is opened only to the lower side, the guide hole portions 326 may be formed on both sides along the axial direction of the frame 321.

The wiring is electrically connected to the light emitting module 310 through the channel 400 of the support beam 200 and the guide hole portion 326 of the frame 321 of the bracket 320. [ That is, the wiring is buried.

At this time, an electric wire (not shown) wired to the channel 400 through the duct 410 may be exposed to the outside at a portion where the electric wire is guided to the guide hole portion 326 of the finishing cap 325. A finishing cover 331 may be disposed between the duct 410 and the finishing cap 325 to block the exposed wiring part. The finishing cover 331 serves to not only prevent exposure of the wiring exposed on the lower side of the heat sink 330, but also to set the position of the frame 321. Of course, the finishing cover 331 can be deformed into various shapes.

 The cover 324 is detachably coupled to the lower side of the frame 321 so as to protect the light emitting module 310 from foreign substances and to disperse the light emitted from the light emitting module 310. In particular, the cover 324 is made of a material capable of transmitting light, and has transparency that can secure a predetermined amount of light transmission. Of course, the cover 324 can be deformed into various shapes.

In addition, the cover 324 can be detachably coupled to the frame 321 in a variety of ways. For convenience, the cover 324 is slidably coupled to the frame 321 along the axial direction.

As the bracket 320 is slidably coupled to the heat sink 330, the coupling portion 340 is extended along the axial direction so that the heat sink 330 having both sides connected to the support beams 200 supports a plurality May be provided.

Since the frame 321 of the bracket 320 can be moved along the heat sink 330 by the engaging portion 340, convenience for the user can be provided.

The engaging portion 340 includes the engaging projection 341, the first engaging recess 342, the receiving recess 343, and the first engaging member 344.

The engaging projections 341 protrude along the axial direction on the opposite side of the bracket 320 that irradiates the light, that is, on the connecting side of the heat sink 330 of the frame 321. At this time, the engaging projections 341 may be integrally formed on the frame 321. [ In particular, the frame 321 and the engaging projection 341 are not limited to the axial length.

The first engaging groove portion 342 is formed on both sides of the engaging projection 341 along the axial direction. At this time, the depth and the number of the first engaging recesses 342 are not limited. Although not shown, the first engagement groove portion 342 may have a stopper at a set position.

The receiving groove portion 343 is recessed in the heat sink 330 to receive the engaging projection 341. [ At this time, the engaging projection 341 may be constrained to the opened upper side of the receiving groove portion 343, or may be inserted in the axial direction of the receiving groove portion 343.

In addition, the first september 344 protrudes from the opposing inner surface of the receiving groove 343 and is slidably inserted into the corresponding first engaging groove 342.

At this time, the first shim member 344 can be restricted from sliding by a stopper (not shown) formed inside the first engagement groove 342. Of course, when the engaging projection 341 is constrained to the opened upper side of the receiving groove 343, the first engaging member 344 is held by the first engaging recess 342 forcibly.

The engaging projection 341 and the first engaging member 344 can be deformed into various shapes.

Accordingly, the bracket 320 can be detachably coupled to the heat sink 330 and is prevented from being arbitrarily detached to the lower side of the heat sink 330.

The engaging portion 340 may further include a second engaging member 345 and a second engaging groove 346 so that the bracket 320 can be more firmly assembled to the heat sink 330. [

The second sandwiching member 345 is formed on both sides of the engaging projection 341 along the axial direction.

In addition, the second engaging groove portion 346 is formed on the inner surface of the receiving groove portion 343 facing each other to receive the second engaging member 345.

That is, the first penetrating member 344 is inserted into the first engaging groove portion 342 while the second engaging member 345 is inserted into the second engaging groove portion 346 to be connected to the support beam 200 The supported heat sink 330 can securely fasten the bracket 320.

Of course, the second engaging groove portion 346 may have a stopper (not shown) to limit the sliding movement of the second engaging member 345. [

Since the engaging projections 341 and the heat sink 330 are relatively long in the axial direction, it is difficult for the first engaging member 344 to slide and be assembled into the first engaging recessed portion 342, It may be difficult to slide the insertion member 345 into the second engagement groove 346 and assemble it.

To prevent this, the heat sink 330 may form an open space 338 which opens to the side where the engaging protrusions 341 formed on the frame 321 of the bracket 320 slide.

The space of the first fitting member 344 and the space of the second engaging recess 346 facing the inside of the receiving recess 343 through the open space 338 can be increased by the heat sink 330 .

In other words, the heat sink 330 forms an open space 338 to be opened in the direction of the engaging projection 341. Then, the heat sink 330 extends the flanges 339 at both side edges along the axial direction.

The heat sink 330 forms the receiving groove 343 by the flange 339. [ At this time, the width of the receiving groove portion 343, which is a direction perpendicular to the axial direction of the heat sink 330, is formed to be wider than the width of the corresponding open space 338.

In addition, each flange 339 forms a first engaging member 344 and a second engaging groove 346.

As a result, the flange 339 is elastically deformed by the open space 338 and the receiving groove 343, and can be spread outwardly.

Therefore, when the first penetrating member 344 is slid into the first engaging groove 342, when the second engaging member 345 is slid into the second engaging groove 346, the facing flange 339 The engaging projections 341 can be easily inserted into the receiving grooves 343 by sliding.

In particular, the heat sink 330 can be further improved in heat dissipation due to the open space 338. As the flange 339 elastically expands both sides of the engaging projection 341 elastically, the bracket 320 can be further bound to the heat sink 330.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand. Accordingly, the true scope of the present invention should be determined by the following claims.
