In particular, the Lambertian light distribution type of the flat LED luminaire is difficult to apply to a variety of spaces or uneven lighting environment, the optical design of the flat LED light fixture is required, and the flat LED luminaire having a Lambertian light distribution type is generally The distribution of light distribution can be controlled through the installation of optical components such as lenses or prisms.

Is preferably combined with The substrate 40 may be a printed circuit board (PCB) substrate on which the first lamp 10 and the second lamp 20, which are LED lamps, are installed, or the first lamp 10 and the second lamp 20. It may be a separate plate member supporting the. In the following description, it is assumed that the substrate 40 is a PCB substrate.
기판(40) 상에서 제1 램프(10) 및 제2 램프(20)는 각각 다수 개로 구비되며 일정한 간격 및 패턴으로 배열된다. 도 2에 도시된 바와 같이 제1 램프(10)와 제2 램프(20)는 2열을 이루며 선형으로 배열될 수 있다.The first lamp 10 and the second lamp 20 on the substrate 40 are each provided in plural and arranged at regular intervals and patterns. As shown in FIG. 2, the first lamp 10 and the second lamp 20 may be linearly arranged in two rows.
리플렉터(30)에는 기판(40)에 결합된 제1 램프(10) 및 제2 램프(20)를 노출시키는 구멍이 형성되며, 이러한 구멍은 제1 램프(10) 및 제2 램프(20)의 형성 위치에 맞도록 일정한 간격 및 배열을 이룬다.The reflector 30 is formed with a hole for exposing the first lamp 10 and the second lamp 20 coupled to the substrate 40, the hole is formed of the first lamp 10 and the second lamp 20 At regular intervals and in alignment to form position.
설명의 편의상, 제1 램프(10)가 노출되는 구멍을 좌측구멍(31), 제2 램프(20)가 노출되는 구멍을 우측구멍(33)으로 정하여 설명한다. 좌측구멍(31)과 우측구멍(33)은 서로 대칭된 형태로 형성되는 것이 바람직하다.For convenience of explanation, the hole in which the first lamp 10 is exposed will be described with the left hole 31 and the hole in which the second lamp 20 is exposed as the right hole 33. The left hole 31 and the right hole 33 are preferably formed in a symmetrical form with each other.
그리고 리플렉터(30)에서 좌측구멍(31)과 우측구멍(33) 간의 대칭의 기준을 이루는 가상의 평면이 대칭면(S)이 된다.In the reflector 30, an imaginary plane which forms a reference for symmetry between the left hole 31 and the right hole 33 becomes the symmetry plane S. As shown in FIG.
리플렉터(30)는 제1 램프(10) 및 제2 램프(20)에서 조사된 빛을 반사시켜 지면 쪽(도로 쪽)으로 비추며, 특히 지면의 수직방향 보다는 도로의 길이방향으로 경사지게 반사되도록 한다. 이를 위하여 리플렉터(30)에는 반사면이 형성되고, 반사면은 제1 반사면(31a), 제2 반사면(31b), 제3 반사면(33a) 및 제4 반사면(33b)을 포함한다. 효과적인 반사를 위하여, 리플렉터(30)의 반사면은 반사율이 우수한 재료로 이루어지거나 반사율이 우수한 물질이 코팅되어 이루어질 수 있다.The reflector 30 reflects the light irradiated from the first lamp 10 and the second lamp 20 to the ground side (road side), in particular to be reflected inclined in the longitudinal direction of the road rather than the vertical direction of the ground. . To this end, a reflecting surface is formed on the reflector 30, and the reflecting surface includes a first reflecting surface 31a, a second reflecting surface 31b, a third reflecting surface 33a, and a fourth reflecting surface 33b. . For effective reflection, the reflecting surface of the reflector 30 may be made of a material having excellent reflectivity or coated with a material having excellent reflectance.
제1 반사면(31a)과 제2 반사면(31b)은 제1 램프(10)에서 조사된 빛을 반사시키기 위한 것이며, 리플렉터(30)의 좌측구멍(31) 상에 형성된다.The first reflecting surface 31a and the second reflecting surface 31b are for reflecting light emitted from the first lamp 10 and are formed on the left hole 31 of the reflector 30.
좌측구멍(31)은 제1 램프(10)에서 조사된 빛이 반사되면서 이동하는 경로를 형성하고, 제1 반사면(31a)과 제2 반사면(31b)은 좌측구멍(31)의 측면을 이룬다. 리플렉터(30)의 중심에서 제2 반사면(31b)을 향하는 방향이 도로방향(도로의 길이방향)이 된다.The left hole 31 forms a path along which the light irradiated from the first lamp 10 is reflected, and the first reflecting surface 31a and the second reflecting surface 31b form side surfaces of the left hole 31. Achieve. The direction from the center of the reflector 30 toward the second reflecting surface 31b becomes the road direction (the longitudinal direction of the road).
제1 반사면(31a)은 제1 램프(10)를 향하여 오목하게 형성되고, 곡면을 형성한다. 제1 반사면(31a)은 일정한 곡률반경을 형성하도록 이루어질 수 있고, 또는 면을 따라 곡률반경이 연속하여 변하도록 이루어질 수 있다.The first reflective surface 31a is concave toward the first lamp 10 and forms a curved surface. The first reflective surface 31a may be configured to form a constant radius of curvature, or may be configured to continuously change the radius of curvature along the surface.
제1 반사면(31a)과 대칭면(S) 사이의 거리는, 기판(40)과 수직한 방향으로 이동함에 따라 변화되고, 특히 기판(40)에서 멀어질수록 그 간격이 넓어진다. The distance between the first reflecting surface 31a and the symmetry plane S changes as it moves in a direction perpendicular to the substrate 40, and the distance between the first reflection surface 31a and the symmetry plane S increases, in particular, as the distance from the substrate 40 increases.
이처럼 제1 반사면(31a)은 제1 램프(10)를 향하여 오목하게 형성됨으로써 제1 램프(10)에서 조사된 빛의 상당부분이 대칭면(S)의 반대 쪽(도로의 길이방향 쪽)을 향하여 진행되도록 한다.As such, the first reflecting surface 31a is formed to be concave toward the first lamp 10 such that a substantial portion of the light irradiated from the first lamp 10 is opposite to the symmetrical surface S (the longitudinal direction of the road). To proceed.
그리고 기판(40)에서 제1 반사면(31a) 바깥쪽(기판(40)과 먼 쪽) 단부까지의 수직 거리는, 기판(40)에서 제2 반사면(31b) 바깥쪽 단부까지의 수직 거리보다 길게 이루어진다.The vertical distance from the substrate 40 to the outer edge of the first reflective surface 31a (far from the substrate 40) is greater than the vertical distance from the substrate 40 to the outer edge of the second reflective surface 31b. It is made long.
제2 반사면(31b)은 제1 램프(10)를 기준으로 제1 반사면(31a)의 반대쪽에 위치하고, 제1 램프(10)를 향하여 볼록하게 이루어진다. 그리고 제2 반사면(31b)과 대칭면(S) 사이의 거리는, 기판(40)과 수직한 방향으로 이동함에 따라 변화되고, 특히 기판(40)에서 멀어질수록 그 간격이 넓어진다.The second reflective surface 31b is positioned opposite to the first reflective surface 31a with respect to the first lamp 10 and is convex toward the first lamp 10. The distance between the second reflecting surface 31b and the symmetry plane S changes as it moves in a direction perpendicular to the substrate 40, and the distance between the second reflection surface 31b and the symmetry plane S increases, in particular, as the distance from the substrate 40 increases.
또한, 제1 반사면(31a)과 제2 반사면(31b) 간의 폭은 제1 램프(10)에서 멀어질수록(기판(40)과 멀어질수록) 넓어진다(d2>d1). 이에 따라, 제1 램프(10)에서 조사된 빛은 제2 반사면(31b)에서 반사됨에 있어서 대체로 대칭면(S)의 반대쪽 방향을 향하여 진행하게 되고, 아울러 제1 반사면(31a)에서 반사된 빛이 제2 반사면(31b)에서 재반사되어 대칭면(S) 쪽을 향하지 않도록 할 수 있으며, 결과적으로 도로의 길이방향을 향하여 충분한 조도의 빛이 반사되도록 한다.Further, the width between the first reflecting surface 31a and the second reflecting surface 31b becomes wider as it moves away from the first lamp 10 (farther from the substrate 40) (d2> d1). Accordingly, the light irradiated from the first lamp 10 travels in a direction opposite to the symmetry plane S, as reflected from the second reflecting surface 31b, and reflected from the first reflecting surface 31a. The light may be reflected back from the second reflecting surface 31b so as not to face the symmetry plane S, and consequently, light of sufficient illuminance is reflected toward the longitudinal direction of the roadway.
좌측구멍(31)상에는, 제1 반사면(31a)과 제2 반사면(31b) 양쪽을 각각 연결하는 측반사면이 형성된다. 즉, 서로 마주하는 제1 반사면(31a)과 제2 반사면(31b) 양쪽 단부를 서로 연결하는 면으로써 2개의 측반사면(31c)이 구비된다.On the left side hole 31, the side reflection surface which connects both the 1st reflection surface 31a and the 2nd reflection surface 31b is formed, respectively. That is, two side reflection surfaces 31c are provided as surfaces connecting both ends of the first reflection surface 31a and the second reflection surface 31b facing each other.
이러한 측반사면(31c) 간의 폭은 램프에서 멀어질수록(기판(40)에서 멀어질수록) 넓어지도록 이루어지는 것이 바람직하며, 이에 의하여 제1 램프(10)에서 조사된 빛이 도로를 가로지르는 방향으로 충분히 조사되도록 한다. 좌측구멍(31)에서의 측반사면(31c)는 우측구멍(33) 상에서도 동일하게 이루어진다.The width between the side reflection surface 31c is preferably made wider as the distance from the lamp (farther from the substrate 40), whereby the light irradiated from the first lamp 10 crosses the roadway. Be sure to investigate enough. The side reflection surface 31c in the left hole 31 is similarly formed on the right hole 33.
제3 반사면(33a)과 제4 반사면(33b)은 제2 램프(20)에서 조사된 빛을 반사시키기 위한 것이며, 리플렉터(30)의 우측구멍(33) 상에 형성된다.The third reflecting surface 33a and the fourth reflecting surface 33b are for reflecting the light irradiated from the second lamp 20 and are formed on the right hole 33 of the reflector 30.
우측구멍(33)은 제2 램프(20)에서 조사된 빛이 반사되면서 이동하는 경로를 형성하고, 제3 반사면(33a)과 제4 반사면(33b)은 우측구멍(33)의 측면을 이룬다.The right hole 33 forms a path through which the light irradiated from the second lamp 20 is reflected, and the third reflecting surface 33a and the fourth reflecting surface 33b form side surfaces of the right hole 33. Achieve.
제3 반사면(33a)은 제2 램프(20)를 향하여 오목하게 형성되고, 곡면을 형성한다. 제3 반사면(33a)은 대칭면(S)을 기준으로 제1 반사면(31a)과 대칭된 형태로 형성되는 것이 바람직하며, 이에 따라 제3 반사면(33a)에 대한 설명은 제1 반사면(31a)에 대한 설명으로 갈음한다.The third reflecting surface 33a is concave toward the second lamp 20 and forms a curved surface. The third reflecting surface 33a is preferably formed to be symmetrical with the first reflecting surface 31a based on the symmetry plane S. Accordingly, the description of the third reflecting surface 33a is described as the first reflecting surface. Substitute the explanation for (31a).
그리고 제1 반사면(31a)과 제3 반사면(33a)의 바깥쪽(기판(40)과 먼 쪽) 단부 간의 폭은, 제1 반사면(31a)과 제3 반사면(33a)의 안쪽(기판(40)과 가까운 쪽) 단부 간의 폭보다 넓게 이루어진다.The width between the end portions of the first reflecting surface 31a and the outer side of the third reflecting surface 33a (far from the substrate 40) is the inner side of the first reflecting surface 31a and the third reflecting surface 33a. It is made wider than the width | variety between the edge part (the side near the board | substrate 40).
제4 반사면(33b)은 제2 램프(20)를 기준으로 제3 반사면(33a)의 반대쪽에 위치하고, 제2 램프(20)를 향하여 볼록하게 이루어진다. 제4 반사면(33b)은 대칭면(S)을 기준으로 제3 반사면(33a)과 대칭된 형태로 형성되는 것이 바람직하며, 이에 따라 제4 반사면(33b)에 대한 설명은 제2 반사면(31b)에 대한 설명으로 갈음한다.The fourth reflective surface 33b is positioned opposite to the third reflective surface 33a with respect to the second lamp 20 and is convex toward the second lamp 20. The fourth reflective surface 33b is preferably formed to be symmetrical with the third reflective surface 33a with respect to the symmetrical surface S, and accordingly, the description of the fourth reflective surface 33b will be described. Substitute the explanation for (31b).
기판(40)에서 제3 반사면(33a) 바깥쪽 단부까지의 수직 거리는, 기판(40)에서 제4 반사면(33b) 바깥쪽 단부까지의 수직 거리보다 길게 이루어진다.The vertical distance from the substrate 40 to the outer end of the third reflecting surface 33a is longer than the vertical distance from the substrate 40 to the outer end of the fourth reflecting surface 33b.
우측구멍(33)상에는, 제3 반사면(33a)과 제4 반사면(33b) 양쪽을 각각 연결하는 측반사면이 형성된다. 즉, 서로 마주하는 제3 반사면(33a)과 제4 반사면(33b) 양쪽 단부를 서로 연결하는 면으로써 2개의 측반사면이 구비된다.On the right side hole 33, the side reflection surface which connects both the 3rd reflection surface 33a and the 4th reflection surface 33b is formed, respectively. That is, two side reflection surfaces are provided as surfaces connecting both ends of the third reflective surface 33a and the fourth reflective surface 33b facing each other.
이러한 측반사면 간의 폭은 램프에서 멀어질수록(기판(40)에서 멀어질수록) 넓어지도록 이루어지는 것이 바람직하며, 이에 의하여 제2 램프(20)에서 조사된 빛이 도로를 가로지르는 방향으로 충분히 조사되도록 한다.The width between the side reflection surfaces is preferably made wider as the distance from the lamp (farther from the substrate 40), so that the light irradiated from the second lamp 20 is sufficiently irradiated in the direction crossing the road. do.
도 4는 본 발명의 다른 실시예에 따른 조명장치(1)를 도시한 단면도이다.4 is a cross-sectional view showing a lighting device 1 according to another embodiment of the present invention.

In this way, the pressing unit 35 may be formed so that the cross section is trapezoidal.
가압유닛(35)이 좌반사판(32)과 우반사판(34)을 가압하는 상태가 유지되도록 하기 위하여, 가압유닛(35)에는 체결유닛(36)이 결합된다.In order to maintain the state in which the pressure unit 35 presses the left reflection plate 32 and the right reflection plate 34, the fastening unit 36 is coupled to the pressure unit 35.
체결유닛(36)은 통상의 나사볼트와 같은 형태로 형성될 수 있고, 기판(40)을 관통한 상태에서 그 단부에 가압유닛(35)과 나사결합될 수 있다.The fastening unit 36 may be formed in the form of a conventional screw bolt, and may be screwed with the pressure unit 35 at its end in the state of penetrating the substrate 40.
그리고 기판(40)과 체결유닛(36)의 헤드 사이에는 체결유닛(36)의 결합상태 유지를 위하여 와셔(37)가 개재될 수 있다.A washer 37 may be interposed between the substrate 40 and the head of the fastening unit 36 to maintain the fastening state of the fastening unit 36.
