Fig.

2A, 2B, and 3, an edge type surface illuminator 200 includes a bracket 210, a surface illumination unit 220, and a frame 230. [

The upper surface of the bracket 210 is fastened to an arbitrary structure (for example, a ceiling surface, a raceway duct in which electric wires are installed, etc.) by using a mounting screw, supporting wire, anchor bolt, hanger or the like.

A plurality of support protrusions 215 and guide protrusions 260 protrude from the lower surface of each of the two circumferential surfaces opposite to each other in the circumferential surface direction of the bracket 210.

As illustrated in FIG. 2A, protrusion through holes 244 may be formed through the support protrusions 215, respectively.

Here, the support protrusions 215 may be formed in positions and sizes corresponding to the slot holes 235 of the frame 230, which will be described later. The protrusion through holes 244 correspond to the size of the fixing pins 410 and the positions of the frame through holes 244 and the arrangement intervals of the protrusion through holes 244 correspond to the arrangement of the frame through holes 244 May be formed to correspond to the intervals.

2a and 4, protrusion through holes 244 are formed for each support protrusion 215, and a plurality of frame through holes 242 are formed to correspond to the protrusion through holes 244, thereby maximizing the installation stability. However, for the sake of convenience of operation, the projection through holes 244 may be formed in only some of the support protrusions 215, and the frame through holes 242 may be formed correspondingly. That is, the projection through-holes 244 may be formed only in one or more supporting protrusions 215 of the plurality of support protrusions arranged on both sides, and the frame through-holes 242 may be formed in corresponding quantities.

As another example, as illustrated in FIG. 2B, a fixing groove 265 corresponding to the size of the fixing pin 410 may be formed at a lower portion of the guide protrusion 260, A frame through hole 242 corresponding to the fixing groove 265 may be formed in a lower portion of the frame 235.

In this case, if the fixing grooves 265 and the frame through holes 245 are positioned on the center line of the bracket 210 and the surface illumination unit 220, the bracket 210 And the surface illuminating unit 220 are fastened at precise positions.

Also in this case, in order to maximize the installation stability, at least one of the support protrusions 215 protruding from the lower surface of the bracket 210 has a protrusion through hole 244 and a corresponding frame through hole 242 And may be formed to be fixed by the fixing pin 410. [

The frame 230 is coupled along the rim of the surface illumination unit 220 to fixly support the surface illumination unit 220 on the lower side and the side surface.

의 형상을 가지도록, 예를 들어 알루미늄 재질의 금형 압출 방식에 의해 일체형으로 제작될 수 있다. 물론, 프레임(230)을 제작하는 방식과 재료가 이로 제한되지 않음은 당연하다.The frame 230 has a cross-sectional shape of C-C ', and a cavity formed inside thereof, as illustrated in FIG. 3, respectively.

For example, by a die extrusion method of an aluminum material. Of course, it is natural that the manner and material of the frame 230 are not limited thereto.

형상 구조의 프레임(230)을 설명함에 있어, 도 3에 예시된 바와 같이 편의상 외측 둘레판(302), 내측 둘레판(304), 상측 둘레판(306) 및 하측 둘레판(308)으로 구분하여 설명한다. 여기서, 공동(空洞)을 형성하는 각 둘레판의 면은 공동 형성면이라 편의상 지칭되고, 면 조명 유닛(220)의 위치를 기준으로 상대적으로 가까운 쪽은 내측으로 지칭하며 먼 쪽은 외측으로 지칭한다. 그러나, 이러한 명칭이 본 발명의 사상을 제한하기 위한 것이 아님은 당연하다.

3, the outer circumferential plate 302, the inner circumferential plate 304, the upper circumferential plate 306, and the lower circumferential plate 308 are divided into a plurality of Explain. Here, the surface of each circumferential plate forming the cavity is referred to as a cavity-forming surface for convenience, and the side relatively closer to the position of the surface illumination unit 220 is referred to as the inside and the side farther is referred to as the outside . However, it is needless to say that these names are not intended to limit the scope of the present invention.

A slot hole 235 is formed in the upper circumferential plate 306 to correspond to the size and position of the support protrusions 215 and the guide protrusions 260. The outer circumferential plate 302 is provided with the above- The frame through holes 244 are formed so as to have a size and an arrangement spacing corresponding to the first through holes 244 (and / or the fixing grooves 265, hereinafter the same).

The fastening structure of the frame 230 and the surface illumination unit 220 will be briefly described with reference to FIG. 3 (a) in which the fastening process of the support protrusion 215 and the slot hole 242 is illustrated.

The surface illumination unit 220 includes a PCB 315, an LED chip 320, a diffusion plate 325, a light guide plate 330, a reflection sheet 335, a silver tape 340, a shock mitigation member 345, back plate 350 as shown in FIG. Of course, it is natural that the configuration of the surface illumination unit 220 may be varied.

The PCB 315 is attached to the inner surface of the inner circumferential plate 304 (that is, the side near the surface illuminating unit 220) using a thermal tape 310, and the LED chip 320, which is a light source, Is fixed to the other surface of the PCB 315. [

The light guide plate 330 is disposed above the diffusion plate 325 to transmit the light emitted from the LED chip 320 to the entire surface.

The diffuser plate 325 is disposed below the light guide plate 330 and is supported on the upper surface of the lower circumference plate 308 which is longer than the length of the upper circumference plate 306 and is exposed inside, .

The reflective sheet 335 is disposed on the upper side of the light guide plate 330 and reflects the light transmitted from the light guide plate 330 downward.

A silver tape 340 for preventing light leakage is fixedly attached to the upper surface of the reflective sheet 335 and a part of the upper circumferential plate 306. The impact mitigating member 345 has a shock The back plate 350 is disposed on the upper portion of the shock absorbing member 345 and is fixed by the step formed on the upper circumferential plate 306. [

As shown in FIG. 3, the upper surface of the upper circumference plate 306 forming the frame 230 is formed with a step having a relatively lower stepped portion on the inner side.

The silver tape 340 is attached up to the position of the upper circumference plate 306 which is formed relatively low and the white plate 350 is fixedly positioned by the step on the upper surface thereof, The phenomenon of leaking in the upward direction of the main body 220 can be effectively prevented.

The outer circumferential plate 302 is extended higher than the connecting position of the upper circumferential plate 306 and the outer circumferential plate 302 is inserted into the slot hole 235 of the upper circumferential plate 306, The side surface can be concealed so as not to be exposed to the outside, and an elegant appearance of the edge type surface illuminator 200 can be secured through the concealment.

The inner circumferential surface of the extended outer circumferential plate 302 is formed in a convex shape as shown in Figure 3B so that the support protrusion 215 is inserted into the slot hole 235 formed in the upper circumferential plate 306 So that the smooth entry of the frame 230 is enabled.

Referring to FIG. 4 illustrating an installation process of the edge type surface illuminator 200, first, the bracket 210 is fixed to an arbitrary structure such as a ceiling or the like, and then a frame (not shown) 230 in the direction of the bracket 210 (step (a)).

The support protrusions 215 and the guide protrusions 260 formed on the bracket 210 enter the slot holes 235 formed in the upper circumferential plate 306 of the frame 230 (Step (b)).

Then, the frame 230 is slid in a direction (step (c)) in such a direction that the projection through-hole 244 formed in the support protrusion 215 communicates with the frame through-hole 244 formed in the outer peripheral plate 302, The fixing pin 410 is inserted so as to be inserted into the communicating frame through hole 244 and the protrusion through hole 244 (step (d)), so that the frame 230 is detached from the bracket 210 and fixed (See FIG. 5).

The fixing pin 410 may be formed to have a bar or a rod shape, or may be formed of a fixed screw shape having a thread on the peripheral surface, a tap bolt, or the like.

The frame through-hole 244 into which the fixing pin 410 is inserted can be finished with a water-soluble putter, a correcting liquid for erasing wrong characters, a sticker, or the like, thereby minimizing the appearance of apparent appearance of unevenness.

Although not shown, a magnet member may be provided on the end side of the fixing pin 410 to allow the fixing pin 410 to maintain a more stable fixed state. Correspondingly, a metal surface attached by a magnetic force may be provided on the cavity forming surface of the inner circumferential plate 304, or the inner circumferential plate 304 itself may be formed of a material adhered to the magnetic force.

In this case, when the end of the fixing pin 410 inserted into the communicating frame through hole 244 and the protrusion through hole 244 reaches the cavity forming surface of the inner circumferential plate 304, The fixed state of the frame 230 and the bracket 210 can be more stably maintained by fixing the fixing member 410 to the inner circumferential plate 304 and fixing the position thereof.
