종래의 터널등이나 가로등은 주로 HID(고휘도방전)램프를 설치하는 경우가 많았으나, 이는 전력의 소비가 많았으며, 쉽게 수명이 다하여 단일체로된 전구를 자주 교체하여야 하는 문제점이 있었으며, 배광의 형태가 둥근모양으로 이루어져있어 가로등 주변 농작물의 성장을 저해하고, 원하는 방향의 배광을 얻지 못하여 광공해를 일으키는 문제점이 있었다.Conventional tunnel lamps and street lamps were often installed with HID lamps, but they consumed a lot of power and had a problem of frequently replacing monolithic bulbs due to their long lifespan. Is composed of a round shape to inhibit the growth of crops around the streetlight, there was a problem causing light pollution because the light distribution in the desired direction is not obtained.

이에 기존의 광원을 대체하여 엘이디램프를 이용한 엘이디 조명기구가 출시되고 있으며, 이 광원(엘이디램프)의 연구가 더욱 활발하게 이루어지고 있는 실정이다.Accordingly, LED lighting equipment using LED lamps has been released in place of existing light sources, and research on this light source (LED lamps) is being actively conducted.

이하, 첨부된 도면을 참조하여 본 발명의 굴절각을 이용하여 최적배광을 갖는 엘이디가로등용 투과판을 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a transmission plate for the LED street lamp having the optimal light distribution using the refractive angle of the present invention.

상기 도면에 도시된 바와 같이, 본 발명에 의한 굴절각을 이용하여 최적배광을 갖는 엘이디가로등용 투과판은 하우징(10)의 내부에 장착된 엘이디램프(15)로부터 발산되는 빛을 투과시키도록 상기 하우징(10)의 개구부에 설치되어 진다.As shown in the drawings, the LED street light transmitting plate having the optimal light distribution using the refractive angle according to the present invention is to transmit the light emitted from the LED lamp 15 mounted inside the housing 10 It is provided in the opening part of (10).

상기 하우징(10)의 가로등지주의 상단에 결합되어 있고, 내부에 엘이디램프(15)가 장착되어 있는 것으로, 통상의 가로등의 구조와 동일함에 따라 본 발명에서는 상기 하우징(10)과 엘이디램프(15)의 구조 및 엘이디램프(15)의 동작원리에 대해서는 더 이상 설명하지 않기로 한다.It is coupled to the upper end of the lamppost of the housing 10, and the LED lamp 15 is mounted therein. As the structure of the conventional street lamp is the same as in the present invention, the housing 10 and the LED lamp 15 ) And the operation principle of the LED lamp 15 will not be described any more.

본 발명의 하우징(10)에는 상기 엘이디램프(15)가 기판에 장착되어 있음에 따라 상기 하우징(10)의 내주면에는 빛을 반사시키는 반사판이 구비되어 있지 않으며, 개구부에 투과판(20)이 결합되어 있다.Since the LED lamp 15 is mounted on the substrate, the housing 10 of the present invention does not include a reflecting plate for reflecting light on the inner circumferential surface of the housing 10, and the transmission plate 20 is coupled to the opening. It is.

본 발명의 상기 투과판(20)은 일정 두께의 판체로 이루어진 것으로, 내측면은 굴곡없이 평평하게 형성되어 있고, 외측면은 투과판(20)의 중앙부를 기준으로 양측에 서로 대칭되게 돌출딘 채 표면이 굴곡되게 다수의 돌출턱(22)이 형성되어 있다.The transmission plate 20 of the present invention is made of a plate body of a predetermined thickness, the inner surface is formed flat without bending, the outer surface is protruded symmetrically on both sides with respect to the central portion of the transmission plate 20. A plurality of protrusions 22 are formed to bend the surface.

따라서, 상기 돌출턱(22)을 통과하면서 빛이 굴절된 후 도로의 지면에 조사되어 지게 되는 것이다.Therefore, the light is refracted while passing through the projection jaw 22 is to be irradiated to the ground of the road.

이때, 조사되는 빛이 좌측 및 우측에 모두 조사되어져 도로의 길이방향으로 최적화된 배광곡선을 갖도록 상기 엘이디램프(15)는 측면발광형(Side Emitting type) 엘이디램프를 사용하도록 한다.In this case, the LED lamp 15 uses a side emitting type LED lamp so that the irradiated light is irradiated on both the left and the right side so as to have a light distribution curve optimized in the longitudinal direction of the road.

또한, 상기 투과판(20)의 굴절율은 1.50~1.70인 것을 사용하도록 한다.In addition, the refractive index of the transmission plate 20 is to be used that is 1.50 ~ 1.70.

여기서, 상기 투과판(20)에 형성된 상기 돌출턱(22)은 상기 투과판(20)의 중앙부 근방에서부터 외측으로 하향 경사지게 돌출되는 다수개의 제1돌출턱(23)과, 상기 제1돌출턱(23)의 외측에서부터 상기 투과판(20)의 양측 단부까지 굴곡되어 형성된 다수개의 제2돌출턱(24)으로 구성되어 진다.Here, the protruding jaw 22 formed in the transmitting plate 20 includes a plurality of first protruding jaws 23 protruding downwardly from the vicinity of the central portion of the transmitting plate 20 to the outside and the first protruding jaws ( It is composed of a plurality of second protrusions 24 formed by bending from the outside of the 23 to both ends of the transmission plate 20.

이때, 상기 제1돌출턱(23)은 상기 엘이디램프(15)가 중앙에 집중되어 위치된 경우 엘이디램프(15)로부터 점차적으로 멀어지는 바깥쪽방향에서도 빛을 효과적으로 굴절시켜 조사시키도록 바깥쪽방향으로 갈수록 경사길이가 길어지게 돌출될 수 있다.In this case, when the LED lamp 15 is centrally located in the center, the first protruding jaw 23 effectively deflects and irradiates light in an outward direction gradually away from the LED lamp 15. Increasingly, the inclined length may protrude longer.

이에 따라, 상기 엘이디램프(15)로부터 조사되는 빛은 도 6과 같이 상기 투과판(20)을 통과하면서 1차적으로 내측방향으로 굴절된 후 상기 제1돌출턱(23)을 통과하면서 2차적으로 외측방향으로 굴절되면서 양측방향으로 더욱 멀리 조사되어 지게 되며, 결국 도로의 양측 길이방향으로 넓게 배광되어져 도 1과 같은 이상적인 배광곡선에 근접한 배광곡선을 얻을 수 있게 되는 것이다.Accordingly, the light irradiated from the LED lamp 15 is first refracted inwardly while passing through the transmission plate 20 as shown in FIG. 6, and then secondly while passing through the first projection step 23. As it is refracted in the outward direction, it is irradiated farther in both directions, and thus is widely distributed in both longitudinal directions of the road, thereby obtaining a light distribution curve close to the ideal light distribution curve as shown in FIG. 1.

따라서, 본 발명에서는 도 1과 같은 이상적인 배광곡선과 같이 가로등으로서의 기능을 최고로 발휘할 수 있는 최적화된 배광을 얻을 수 있게 되는 것이다.Therefore, in the present invention, it is possible to obtain an optimized light distribution capable of maximally exhibiting a function as a street light, such as an ideal light distribution curve as shown in FIG. 1.

그리고, 본 발명의 투과판(20)은 엘이디램프(15)를 외부로부터 보호함과 아울러 조사되는 빛을 용이하게 투과시키도록 그 소재를 클리어 폴리카보네이트(Clear Polycarbonate) 재질로 하여 성형하고, 상기 클리어 폴리카보네이트는 90%의 투과율을 갖는 것을 사용한다.In addition, the transparent plate 20 of the present invention is formed of a clear polycarbonate material to protect the LED lamp 15 from the outside and easily transmit the irradiated light, and the clear Polycarbonate is used that has a transmittance of 90%.

한편, 본 발명의 상기 제2돌출턱(24)은 상기 투과판(20)의 양측단부로 갈수록 굴곡길이(L)가 짧아지게 형성되어 진다.On the other hand, the second protruding jaw 24 of the present invention is formed such that the bending length (L) becomes shorter toward both ends of the transmission plate (20).

이때, 상기 제2돌출턱(24)은 상기 투과판(20)의 표면에서 외측방향으로 하향경사지게 돌출되는 제1경사면(25)과, 상기 제1경사면(25)의 돌출된 단부에서 상기 투과판(20)의 표면으로 상향경사지게 형성되는 제2경사면(26)으로 이루어지며, 각각의 상기 제2돌출턱(24)의 제2경사면(26) 길이는 상기 투과판(20)의 바깥쪽으로 갈수록 짧아지는 것이 바람직하다.In this case, the second projection jaw 24 has a first inclined surface 25 protruding downward from the surface of the transmissive plate 20 in an outward direction, and the transmissive plate at the protruding end of the first inclined surface 25. The second inclined surface 26 is formed to be inclined upward to the surface of the (20), the length of the second inclined surface 26 of each of the second protrusions 24 is shorter toward the outside of the transmission plate 20 It is desirable to lose.

따라서, 상기 엘이디램프(15)로부터 조사되는 빛이 좁은 각도로 상기 투과판(20)을 통과하더라도 상기 투과판(20)을 통과하면서 굴절된 빛을 상기 제2경사면(26)을 통해 바깥쪽인 외측방향으로 효과적으로 굴절시킬 수 있게 되는 것이다.Therefore, even though the light irradiated from the LED lamp 15 passes through the transmission plate 20 at a narrow angle, the light refracted while passing through the transmission plate 20 is outside through the second slope 26. It can be effectively refracted in the outward direction.
