[도 1]은 본 발명에 따른 엘이디 평판 조명기구의 개략적인 전체구성도이고, [도 2]는 본 발명에 따른 엘이디 평판 조명기구의 일부를 발췌하여 도시한 구성도를 나타낸다.1 is a schematic overall configuration diagram of the LED flat light fixture according to the present invention, Figure 2 is a schematic view showing a part of the LED flat light fixture according to the present invention.

[도 1] 및 [도 2]를 참조하면, 본 발명에 따른 엘이디 평판 조명기구는 LED 프레임(10), LED 회로기판(20), LED 램프(30)를 포함하여 구성된다.1 and 2, the LED flat light fixture according to the present invention comprises an LED frame 10, LED circuit board 20, LED lamp 30.

먼저, LED 프레임(10)은 그 중앙부가 상방을 향해 장방형으로 외향하는 절곡부(11)가 형성되며, 이 절곡부의 하면 일측에 복수 개의 전원커넥터(12)가 형성된다.First, the LED frame 10 is formed with a bent portion 11, the center portion thereof outward in a rectangular direction upward, a plurality of power connector 12 is formed on one side of the lower surface of the bent portion.

그리고 LED 회로기판(20)은 절곡부(11)의 하면에 LED 프레임의 길이 방향(이하, "Y축 방향"이라 함)을 따라 나란히 인접하여 복수 개 장착되며, LED 회로기판의 일측에 형성된 연결단자(22)가 LED 프레임에 형성된 전원커넥터(12)에 접속됨으로써 외부의 SMPS(P)로부터 LED 회로기판(20)에 부착된 개개의 LED 램프에 전원이 인가된다.In addition, a plurality of LED circuit boards 20 are mounted on the lower surface of the bent portion 11 adjacent to each other along the length direction of the LED frame (hereinafter, referred to as a “Y-axis direction”), and are formed on one side of the LED circuit board. The terminal 22 is connected to the power connector 12 formed in the LED frame, so that power is applied to the individual LED lamps attached to the LED circuit board 20 from the external SMPS (P).

이를 위해 LED 회로기판(20)에는 전원커넥터(12)와 통전하기 위한 결선회로(21)가 패터닝되며, 상세하게 LED 프레임(10)에 형성된 전원커넥터(12)와 LED 회로기판(20)에 형성된 연결단자(22)가 상호 탈착 가능하게 접속되고, 연결단자(22)는 LED 회로기판(20)에 패터닝된 결선회로(21)와 통전된다.For this purpose, the connection circuit 21 for energizing the power connector 12 is patterned on the LED circuit board 20, and the power connector 12 formed on the LED frame 10 and the LED circuit board 20 are formed in detail. The connection terminals 22 are detachably connected to each other, and the connection terminals 22 are energized with the connection circuit 21 patterned on the LED circuit board 20.

LED 램프(30)는 LED 회로기판에 복수 개 부착된 상태로 결선회로에 통전되어 발광하며, LED 램프의 배열구조에 대해서는 아래의 [도 3] 및 [도 4]를 통해 보다 상세히 설명한다.
The LED lamp 30 is energized by the connection circuit in a state where a plurality of LED circuit boards are attached to the light emitting circuit, and the arrangement structure of the LED lamp will be described in more detail with reference to FIGS. 3 and 4 below.

[도 3]은 본 발명의 LED 회로기판을 도시한 구성도이고, [도 4]는 본 발명에 따른 LED 회로기판의 배치 구성도를 나타낸다.3 is a configuration diagram showing an LED circuit board of the present invention, and FIG. 4 is a layout diagram of the LED circuit board according to the present invention.

[도 3] 및 [도 4]를 참조하면, 본 발명의 LED 램프(30)는 LED 회로기판에 부착된 상태로 결선회로에 통전되어 발광하며, Y축 방향을 따라 LED 회로기판(20)에 등간격으로 배열되는 세로열을 형성하고, 세로열(L1, L2, L3, L4, L5, L6, L7)은 Y축 방향에 대해 직각 방향(이하, "X축 방향"이라 함)을 따라 LED 회로기판(20)에 복수 개 형성된다.Referring to FIGS. 3 and 4, the LED lamp 30 of the present invention is energized in the connection circuit in a state where it is attached to the LED circuit board, and emits light. The LED lamp 30 is connected to the LED circuit board 20 along the Y-axis direction. Form vertical columns arranged at equal intervals, and the vertical columns (L1, L2, L3, L4, L5, L6, L7) are LEDs along the direction perpendicular to the Y-axis direction (hereinafter referred to as "X-axis direction"). A plurality of circuit boards 20 are formed.

또한, LED 램프(30)의 세로열(L1, L2, L3, L4, L5, L6, L7)은 LED 회로기판(20)간의 연접부분에서도 등간격으로 배열되어 절곡부(11) 전면(全面)에 균일한 발광을 구현한다.In addition, the vertical columns L1, L2, L3, L4, L5, L6, and L7 of the LED lamp 30 are arranged at equal intervals at the junctions between the LED circuit boards 20, so that the front of the bent part 11 is entirely formed. Uniform light emission is achieved.

세로열(L1, L2, L3, L4, L5, L6, L7)은 상기 X축 방향을 따라 홀수 개 형성되고, 세로열은 세로열 중 중앙에 위치하는 중심열(L4)을 기준으로 좌우 대칭되며, 세로열(L1, L2, L3, L4, L5, L6, L7) 사이의 간격(d1, d2, d3, d4, d5, d6)은 중심열(L4)에 인접할수록 상대적으로 멀게 형성되고, 중심열(L4)에 배열되는 LED 램프(30)의 이격거리는 세로열(L1, L2, L3, L5, L6, L7)에 배열되는 LED 램프(30)의 이격거리보다 상대적으로 더 가깝게 형성된다.The number of columns L1, L2, L3, L4, L5, L6, and L7 is odd along the X-axis direction, and the columns are symmetrically with respect to the center column L4 located at the center of the columns. , The intervals d1, d2, d3, d4, d5, and d6 between the columns L1, L2, L3, L4, L5, L6, and L7 are relatively farther and closer to the center column L4. The spacing of the LED lamps 30 arranged in the row L4 is formed relatively closer than the spacing of the LED lamps 30 arranged in the vertical columns L1, L2, L3, L5, L6, L7.

상세하게, 세로열은 세로열 중 중앙에 위치하는 중심열(L4)을 기준으로 좌우 대칭이므로 [도 3] 및[ 도 4]에서 d1 = d6, d2 = d5, d3 = d4 이고, d1 < d2 < d3 인 크기를 나타낸다.In detail, since the column is symmetric with respect to the center column L4 located at the center of the column, d1 = d6, d2 = d5, d3 = d4 in FIGS. 3 and 4, and d1 <d2. size is <d3.

즉 중심열(L4)에서 X축 방향의 외곽으로 갈수록 세로열 사이의 발광 겹침이 적어지게 되므로 상대적으로 세로열 사이의 간격을 좁게 형성한다(d1 <d2 <d3, d4 > d5 > d6).That is, since the light emission overlap between the vertical columns decreases from the central column L4 to the outer side in the X-axis direction, the intervals between the vertical columns are relatively narrow (d1 <d2 <d3, d4> d5> d6).

또한, 즉 중심열(L4)에서 X축 방향의 외곽으로 갈수록 세로열 사이의 간격을 좁게 형성함과 더불어 중심열(L4)에 등간격으로 배치된 LED 램프(30)의 개수를 나머지 세로열(L1, L2, L3, L5, L6, L7)에 등간격으로 배치된 LED 램프(30)의 개수보다 많게 배열하여 LED 회로기판(20)에 부착된 LED 램프(30)의 전체적인 배열을 고르게 하였다.In other words, as the gap between the vertical columns becomes narrower from the central column L4 to the outer side in the X-axis direction, the number of the LED lamps 30 arranged at equal intervals in the central column L4 is divided into the remaining vertical columns ( L1, L2, L3, L5, L6, and L7 are arranged more than the number of LED lamps 30 arranged at equal intervals to uniform the overall arrangement of the LED lamp 30 attached to the LED circuit board 20.

개개의 LED 램프(30)에 인가되는 정전압을 고려하여 위와 같이 배열함으로써 LED 램프(30)로부터 생성되는 발열을 임계한도 이하로 낮추어 LED 램프(30)의 내구성을 양호하게 유지함과 동시에 LED 프레임의 절곡부 전면에 균일한 발광을 구현할 수 있게 된다.By arranging as above in consideration of the constant voltage applied to the individual LED lamps 30, the heat generated from the LED lamps 30 is lowered below a critical limit, thereby maintaining the durability of the LED lamps 30 and at the same time bending the LED frame. It is possible to implement uniform light emission on the entire front surface.

한편, LED 프레임(10)은 중앙부가 상방을 향해 장방형으로 외향하는 절곡부(11)가 형성되는데, 이렇게 장방형으로 상향 돌출된 절곡부(11)가 천정에 끼워지게 되며, 이러한 절곡부(11)의 깊이는 기존 설치 구조를 유지하는 위해서 그 구조를 변경하는 것이 비효율적인 면이 많다.On the other hand, the LED frame 10 is formed with a bent portion 11, the central portion outwards in a rectangular direction upward, such that the bent portion 11 protruding upward in the rectangular is fitted to the ceiling, such a bent portion 11 In many cases, it is inefficient to change the depth of the structure in order to maintain the existing installation structure.

이와 같은 점도 고려하여 기존의 LED 프레임(10) 구조를 그대로 유지한 상태로 LED 프레임의 절곡부 전면에 균일한 발광을 구현할 수 있게 된다.In consideration of such a point, it is possible to implement uniform light emission on the front of the bent portion of the LED frame while maintaining the structure of the existing LED frame 10 as it is.

그리고, LED 램프(30)의 세로열(L1, L2, L3, L4, L5, L6, L7)은 LED 회로기판(20)간의 연접부분에서도 LED 램프가 등간격으로 배열된다. 상세하게 하나의 LED 회로기판(20)에 배열된 LED 램프(30)간 이격거리(a1, b1)와 LED 회로기판(20) 연접부분의 LED 램프(30)간 이격거리(a2, b2)가 등간격으로 배열된다(a1 = a2, b1 = b2).In the vertical columns L1, L2, L3, L4, L5, L6, and L7 of the LED lamps 30, the LED lamps are arranged at equal intervals at the junctions between the LED circuit boards 20. In detail, the separation distances a1 and b1 between the LED lamps 30 arranged on one LED circuit board 20 and the separation distances a2 and b2 between the LED lamps 30 at the junction portion of the LED circuit board 20 are provided. Arranged at equal intervals (a1 = a2, b1 = b2).

이로 인해, Y축 방향으로 길게 형성된 LED 프레임(10)에 복수 개의 LED 회로기판(20)이 나란히 연접하여 부착되는 경우에도 LED 프레임(10)의 전면에 균일한 발광을 유지할 수 있게 된다.
As a result, even when the plurality of LED circuit boards 20 are connected in parallel to the LED frame 10 formed in the Y-axis direction, the uniform light emission may be maintained on the front surface of the LED frame 10.

[도 5]는 본 발명에 따른 결선회로의 개략적인 구성도로서, [도 5]를 참조하면, 본 발명의 결선회로(21)는 LED 램프의 일정 개수에 대응하는 저항이 직렬로 결선된 복수 개의 제 1 결선(21a); 복수 개의 제 1 결선을 상호 병렬로 결선하는 제 2 결선(21b);을 포함하여 구성된다.5 is a schematic configuration diagram of a connection circuit according to the present invention. Referring to FIG. 5, the connection circuit 21 of the present invention has a plurality of resistors corresponding to a predetermined number of LED lamps connected in series. First wirings 21a; And a second connection 21b for connecting a plurality of first connections in parallel to each other.

이와 같은 제 1 결선(21a)의 설계를 통하면 개개의 LED 램프(30)에 대한 로드를 균일하고 셋팅할 수 있으므로 LED 램프(30)들의 고른 내구성을 유지할 수 있고, 무엇보다 이와 같은 배열구조로 스팟 현상이 발생하지 않으면서 균일한 발광을 구현할 수 있게 된다.
Through the design of the first connection 21a, the loads for the individual LED lamps 30 can be uniformly set, and thus the durability of the LED lamps 30 can be maintained evenly. It is possible to implement uniform light emission without generating a spot phenomenon.

[도 6]은 본 발명의 LED 회로기판을 도시한 또 다른 구성도로서, [도 6]을 참조하면, 복수 개의 제 1 결선(21a) 중 하나의 제 1 결선에 직렬로 결선된 LED 램프(30)의 개수와 다른 하나의 제 1 결선에 직렬로 결선된 LED 램프(30)의 개수는 동일하게 구비된다.FIG. 6 is another configuration diagram illustrating an LED circuit board of the present invention.
