본 발명의 라이팅파이프(100)는, 광원(200)의 빛이 투입되는 집광부(110)가 일단에 구비되는 바형상으로 일정한 각도로 절곡되는 절곡부(130)가 일체로 형성된다.The lighting pipe 100 of the present invention is integrally formed with a bent portion 130 bent at a predetermined angle in a bar shape provided at one end of the light collecting portion 110 to which the light of the light source 200 is input.

이때, 상기 절곡부(130)에는 일정각도를 유지하면서 면상의 절단되는 챔퍼(135)를 형성한다. At this time, a chamfer 135 that is cut in a plane shape is formed in the bent portion 130 while maintaining a predetermined angle.

그리고, 상기 집광부(110)는, 광을 모을 수 있도록 내측으로 함몰되는 오목부(115)가 구비되어도 좋다.In addition, the light collecting unit 110 may be provided with a concave portion 115 recessed inward to collect light.

더하여, 상기 라이팅파이프(100)는, 외측표면을 따라 빛이 굴절토록 요철형태를 갖는 복수의 난반사면(170)이 일체로 형성되어도 좋다.In addition, the lighting pipe 100 may be integrally formed with a plurality of diffuse reflection surfaces 170 having a concave-convex shape so that light is refracted along the outer surface.

또한, 상기 챔퍼(135)는 집광부의 중심에서 30~40도의 각도를 유지토록 설치된다.In addition, the chamfer 135 is installed to maintain an angle of 30 to 40 degrees from the center of the light collecting part.

계속하여, 상기 챔퍼(135) 역시 내측으로 함몰되는 반사면(138)이 더 구비되어도 좋다.Subsequently, the chamfer 135 may also further include a reflective surface 138 recessed inward.

상기와 같은 구성으로 이루어진 본 발명의 동작을 설명한다.The operation of the present invention configured as described above will be described.

도2 내지 도6에서 도시한 바와같이 본 발명의 라이팅파이프(100)는, 광원(200)의 빛이 투입되는 집광부(110)가 일단에 구비되는 바형상으로 일정한 각도로 절곡되는 절곡부(130)가 일체로 형성되어 광원(200)을 발광시키면 일정길이를 갖는 바 형상의 라이팅조명 전체가 일정한 조도로 발광토록 한다.As shown in FIGS. 2 to 6, the lighting pipe 100 of the present invention has a bar-shaped bending part bent at a constant angle in which the light collecting part 110 to which the light of the light source 200 is input is provided at one end ( When 130) is integrally formed and the light source 200 emits light, the entire bar-shaped lighting light having a certain length emits light with a constant illuminance.

이때, 상기 절곡부(130)에는 일정각도를 유지하면서 면상의 절단되는 빗면 구조의 챔퍼(135)를 형성하여 집광부(110)를 통하여 투입되는 빛을 반사시켜 라이팅파이프의 길이방향으로 빛을 모아주게 된다.At this time, a chamfer 135 of an inclined plane structure to be cut is formed in the bent part 130 while maintaining a certain angle, and the light input through the light collecting part 110 is reflected to collect the light in the longitudinal direction of the lighting pipe. will give

그리고, 상기 집광부(110)는, 광을 모을 수 있도록 내측으로 함몰되는 오목부(115)가 구비되어 집광부로 투입되는 광원(200)의 빛이 라이팅파이프의 내경을 향하여 집중토록 되어 빛의 손실을 최소화 한다.In addition, the light collecting unit 110 is provided with a concave portion 115 recessed inside to collect the light, so that the light of the light source 200 injected into the light collecting unit is concentrated toward the inner diameter of the lighting pipe. Minimize loss.

더하여, 상기 라이팅파이프(100)는, 외측표면을 따라 빛이 굴절토록 요철형태를 갖는 복수의 난반사면(170)이 일체로 형성되어 챔퍼(135)를 통하여 빛의 손실없이 반사되는 빛이 라이팅파이프 전체에 균일하게 분포토록 된다.In addition, the lighting pipe 100 is integrally formed with a plurality of diffuse reflection surfaces 170 having a concave-convex shape so that light is refracted along the outer surface, and the light reflected without loss of light through the chamfer 135 is the lighting pipe evenly distributed throughout.

또한, 상기 챔퍼(135)는 도3에서 도시한 바와같이 챔퍼의 경사각도(a)는 집광부의 중심에서 30~40도의 각도를 유지토록 설치되는 것이 바람직하며, 30이하 및 40도 이상일 경우 빛의 라이팅파이프의 길이방향으로 균일하게 전달되는 못하게 된다. In addition, as shown in FIG. 3, the chamfer 135 is preferably installed so that the inclination angle (a) of the chamfer is maintained at an angle of 30 to 40 degrees from the center of the light collecting part. of the lighting is not transmitted uniformly in the longitudinal direction of the pipe.

계속하여, 상기 챔퍼(135) 역시 내측으로 함몰되는 반사면(138)이 더 구비하면 오목거울의 원리를 통하여 반사되는 빛이 라이팅파이프의 직경방향 전방향을 향하여 균일하게 반사토록 된다.Subsequently, if the chamfer 135 is also further provided with a reflective surface 138 that is recessed inward, the light reflected through the principle of a concave mirror is uniformly reflected in the omnidirectional radial direction of the lighting pipe.

이상과 같이 본 발명의 챔퍼를 갖는 라이팅파이프를 적용하면 도4와 같이 왼쪽의 별도의 챔퍼가 없는 경우 일반라이팅파이프(900)광원의 투입부에만 핫 스팟(p1)이 형성되면서 대부분의 광(L)이 외부로 노출토록 되나 본원발명의 챔퍼(135)를 외부로 손실되는 광이 최소화 되면서 대부분의 광이 라이팅파이프의 내측을 따라 이동토록 된다.When the lighting pipe having the chamfer of the present invention is applied as described above, as shown in FIG. 4 , if there is no separate chamfer on the left side, a hot spot p1 is formed only at the input portion of the general lighting pipe 900 light source, and most of the light (L) ) is exposed to the outside, but the light lost through the chamfer 135 of the present invention to the outside is minimized, and most of the light moves along the inside of the lighting pipe.

즉, 본원발명의 라이팅파이프(100)는, 전체에서 균일한 조도분포가 가능토록 되나 일반라이팅파이프(900)는 핫스팟에서 최대의 전체에서는 낮은 조도분포를 갖도록 되는 것이다.That is, in the lighting pipe 100 of the present invention, a uniform illuminance distribution is possible throughout, but the general lighting pipe 900 has a low illuminance distribution at the maximum in the hot spot.
