Description

가로등용 엘이디 램프{LED lamp for street light}LED lamp for street light {LED lamp for street light}

본 발명은 가로등용 LED 램프에 관한 것으로, 보다 상세하게는, 광원으로 LED를 사용하여 전력소모를 현저하게 줄이면서도, 집광렌즈를 사용하여 빛의 선명도와 조도(照度)를 향상시킬 뿐만 아니라, 기존 시설에서 램프만 교체함으로써 기존에 사용해오던 가로등 시설을 그대로 이용할 수 있는 가로등용 LED 램프에 관한 것이다.The present invention relates to an LED lamp for a street lamp, and more particularly, to significantly reduce power consumption by using LED as a light source, and to improve light clarity and illuminance by using a condenser lens, The present invention relates to a street lamp LED lamp that can be used as it is by replacing only the lamp in the facility.

가로등은 가로(街路) 교통의 안전과 보안을 위하여 가로를 따라서 설치한 조명시설로, 고속도로, 시가지의 주요도로, 상업지구 도로, 주택지구 도로, 공원 등 설치장소에 따라 다양한 종류가 사용된다. 가로등 전주의 형식에도 여러 가지가 있는데, 전주의 끝에 등을 다는 하이웨이형, 전주의 끝부분에 가로로 가지를 뻗게 하여 거기에 등을 다는 브래킷형, 전주의 꼭대기에 등을 다는 주두형(柱頭型) 등이 있고, 광원(光源)으로는 고압수은등, 형광등, 나트륨등, 메탈할라이트(Metal Halide) 램프 등이 사용된다.Street lamps are lighting facilities installed along the streets for the safety and security of street traffic. Various types of street lamps are used depending on the installation places such as highways, main roads in the city, commercial roads, residential roads, and parks. There are many types of streetlight poles, including a highway type with a back at the end of the pole, a bracket with a back at the end of the pole, and a head shape with a back at the top of the pole. And a high-pressure mercury lamp, a fluorescent lamp, a sodium lamp, a metal halide lamp, and the like are used as the light source.

가로등으로 출현한 기술은 수없이 많은데, 그 중 하나의 예를 들면 실용신안등록 제389219호 "가로등"인데, 도 1을 참조하여 간략히 설명하면, 지주의 상부에 배치되는 투광기(1)의 내부에 램프(2), 반사갓(3), 막음구(4) 및 안정기(5)를 배치하고 커버(9)를 체결하여 구성되고, 램프(2)는 일측에 위치하는 소켓(7)에 결합되며, 안정기(5)는 투광기(1) 내에서 격벽(6)으로 구획된 공간에 배치되도록 구성되어 있다.There are a number of technologies that appear as street lights, one of which is, for example, Utility Model Registration No. 389219 "Street Lamp". Briefly described with reference to FIG. 1, the interior of the light projector 1 disposed above the prop It is configured by arranging the lamp 2, the reflector 3, the blocking hole 4 and the ballast 5 and fastening the cover 9, the lamp 2 is coupled to the socket 7 located on one side, The stabilizer 5 is comprised so that it may be arrange | positioned in the space partitioned by the partition 6 in the light projector 1.

상기한 종래의 기술적 구성은 투광기 내부를 격벽으로 구획하여 일측 공간에 안정기를 배치하고 타측 공간에 램프 및 반사갓을 배치시킨 구조로 램프의 교체 및 수리가 간편하도록 한 것인데, 커버가 완전 밀폐되도록 체결할 수 없기 때문에 날 벌레나 각종 이물질이 투광기 내부로 침입하여 반사효율이 저하되는 문제점이 발생됨은 물론 냉·온 차이에 따른 습기도 발생하여 조도효율이 저하되고, 또한 램프의 교체나 수리시에 등기구 커버를 분리한 후 다시 조립하여야 하므로 구조적으로 복잡하다는 문제점이 있다.The conventional technical configuration is to divide the interior of the floodlight into a partition wall so that the ballast in one space and the lamp and the reflector in the other space to simplify the replacement and repair of the lamp, the cover is to be closed tightly Because of this problem, blades and various foreign matters penetrate the inside of the light emitter, resulting in a decrease in reflection efficiency, as well as moisture caused by a difference between cold and hot temperatures, resulting in a decrease in illuminance efficiency. There is a problem that the structural complexity because it must be assembled again after separating.

또, 안정기는 통상 가로등 전주의 하단부에 내장되어 사용되기 때문에 장마나 홍수 등에 의한 침수시 누전ㆍ감전 등의 사고가 빈번히 발생하고, 안정기 주변에 차단스위치 및 전선연결용 단자를 고정하는 기판이 설치되는 등 안정기의 교체나 점검, 수리, 설치작업 등을 하기가 매우 까다로운 문제가 있을 뿐만 아니라 가 로등의 전주 하단부에 안정기를 내장해야 하기 때문에 전주의 하단부 직경이 최소 220㎜가 되어야 하므로 전주의 크기가 커져서 외관도 좋지 않고 제작 및 설치비용도 많이 드는 문제가 있다. In addition, ballasts are usually built into the lower end of streetlight poles, so accidents such as short circuits and electric shocks during flooding due to rainy seasons and flooding occur frequently, and boards are provided around the ballasts for fixing cutoff switches and wire connection terminals. It is not only difficult to replace, check, repair, or install the ballast, but also because the ballast must be built in the lower pole of the street lamp, the diameter of the pole should be at least 220mm. There is a problem that the appearance is not good and the production and installation costs are also high.

한편, 일반적으로 가로등에 사용되는 광원으로, 나트륨등은 연색성(演色性, color rendering)이 떨어져 사물의 색감이 떨어질 뿐만 아니라 광원에서 일정 거리 이격되면 조도가 현저히 떨어지는 문제점이 있고, 형광등은 빛이 부드럽고 열을 거의 수반하지 않는 이점과 백열등에 비해 소모전력도 적다는 이점은 있으나, 전압이 높으면 흑화(黑化)가 진행되어 수명이 짧아지고 전압이 낮으면 점등되지 않으며, 점멸 횟수가 많아짐에 따라 그만큼 수명이 단축되고, 주위의 온도에 의하여 특성이 변동하고, 0∼40℃ 범위 외에서는 점등하기 어렵고 밝기도 저하하며, 수명이 지난 형광등은 열화하여 광속(光束)이 감퇴하므로 비경제적이다. On the other hand, as a light source generally used for street lamps, sodium lamps have a problem in that color rendering is poor, and thus the color of the object is degraded. It has the advantage of almost no heat and consumes less power than incandescent lamps, but when the voltage is high, blackening proceeds and the life is shortened.When the voltage is low, it does not light up and the number of flashes increases. Its life is shortened, its characteristics fluctuate due to ambient temperature, it is difficult to light outside the range of 0 to 40 ° C., its brightness is also lowered, and it is uneconomical because its fluorescent lamp deteriorates due to deterioration of luminous flux.

그러나, 상기와 같은 문제점을 해결하기 위하여 가로등 전체를 교체하기에는 막대한 비용이 발생하므로 종래 가로등 시설, 즉 지주 및 투광기를 그대로 이용하면서 조도(照度)를 대폭 향상시키면서 상기와 같은 문제점을 해결하기 위한 가로등의 개발이 절실하다고 하겠다. However, in order to solve the above problems, a huge cost is required to replace the entire street light, so that the street lamp for solving the above problems while greatly improving the illuminance while using a conventional street light facility, that is, a strut and a floodlight. Development is urgent.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로 본 발명의 목적은, 광원으로 LED를 사용하여 전력소모를 현저하게 줄이면서도, LED를 실장한 LED 모듈을 집광렌즈와 일체로 결합시킴으로써 램프를 덮기 위한 별도의 커버가 필요하지 않아 구조도 간단할 뿐만 아니라 빛이 선명하고 조도(照度)가 높으며, 기존 시설에서 램프만 교체함으로써 기존에 사용해오던 가로등 시설을 그대로 이용할 수 있는 가로등용 LED 램프를 제공하기 위한 것이다.The present invention has been made to solve the above problems, an object of the present invention, while significantly reducing the power consumption by using the LED as a light source, by combining the LED module mounted with the LED and the condenser lens integrally It does not need a separate cover to cover, so it is not only simple in structure but also bright in light and high in illuminance, and replaces lamp in existing facility to provide LED lamp for street lamp that can use existing street lamp facility. It is to.

이상에서 설명한 것과 같은 본 발명에 따른 가로등용 LED 램프는, 광원으로 LED를 사용했기 때문에 전력소모가 현저하게 줄어들고, LED를 실장한 LED 모듈을 집광렌즈와 일체로 결합시킴으로써, 렌즈가 광(光)을 모아 확산시킴은 물론 커버 역할도 하기 때문에 램프를 덮기 위한 별도의 커버가 필요하지 않아 구성도 간단할 뿐만 아니라 빛이 선명하고 조도(照度)가 높으며, 기존 시설에서 램프만 교체함으로써 기존에 사용해오던 가로등 시설을 그대로 이용할 수 있어 경제적이다.In the LED lamp for streetlight according to the present invention as described above, since the LED is used as a light source, the power consumption is significantly reduced, and by combining the LED module mounted with the LED integrally with the condensing lens, the lens is light. It does not need a separate cover to cover the lamp because it collects and spreads it, and also serves as a cover, so it is not only simple in configuration but also bright in light and high in illuminance. It is economical because street lamps can be used as it is.

또한, 본 발명에 따른 가로등용 LED 램프는, LED를 사용하기 때문에 일반 가로등과 같이 불이 켜질 때까지 오랫동안 기다릴 필요없이 스위치가 on 되는 순간 즉시 점등되고, 점등시 깜박거림이나 웅웅거리는 잡음이 없으며, 고압을 사용하지 않기 때문에 높은 전압으로 인한 먼지가 쌓여 전등갓이 시커멓게 변해 조도를 감소시키는 일이 없으며, LED를 점등시키기 위하여 AC를 DC로 변환시키기 위한 콘버터를 내장하고 있어서 별도의 콘버터가 필요하지 않고, 기존에 가로등 전주에 내장시켰던 부품들을 램프에 내장시켰기 때문에 가로등 전주를 슬림화할 수 있어서 제작 및 설치비용이 적게 들 뿐만 아니라 외관도 아름답다.In addition, the LED lamp for street light according to the present invention, because the LED is used, without the need to wait for a long time until the light is turned on like a normal street light is turned on at the moment the switch is turned on, there is no flickering or hum when turned on, Since no high pressure is used, dust from the high voltage accumulates and the lamp shade turns dark, reducing the illuminance, and a built-in converter for converting AC to DC to turn on the LED does not require a separate converter. Since the parts that were built into the street lamp pole are built into the lamp, the street lamp pole can be made slim, so the production and installation cost is low and the appearance is beautiful.

본 발명에 따른 가로등용 LED 램프는, 균일하게 배치된 다수개의 LED를 실장한 LED 모듈(10'), 상기 LED 모듈(10')에 결합되고 각각의 LED에 대응되게 집광렌즈를 배치시켜 렌즈 전체를 일체화한 렌즈모듈(10), 상기 LED 모듈(10')에서 발생하는 열을 방출시키기 위한 방열기(12), 상기 LED에 전원을 공급하기 위한 소켓부(14)를 포함하여 구성된다.LED lamp for street light according to the present invention, the LED module 10 'mounted with a plurality of LEDs arranged uniformly, coupled to the LED module 10' and the condenser lens disposed corresponding to each LED, the entire lens It comprises a lens module 10 integrated with a, a radiator 12 for dissipating heat generated from the LED module 10 ', and a socket portion 14 for supplying power to the LED.

렌즈모듈(10)은 각각 광학렌즈인 집광렌즈를 일체화시킨 것으로, 그 형상은 장방형이며, 도 2에 도시한 것과 같은 제1실시예에서는 렌즈모듈(10)을 1개만 구비하지만, 도 4와 5에 도시한 것과 같은 제2실시예에서는 렌즈모듈(10)을 2∼6개, 즉 짝수개씩을 배치할 수도 있다.The lens module 10 is integrated with a condenser lens, each of which is an optical lens, and has a rectangular shape. In the first embodiment as shown in FIG. 2, only one lens module 10 is provided. In the second embodiment as shown in the figure, two to six lens modules 10 may be arranged.

도 2와 3에 도시한 제1실시예의 방열기(12)에 대하여 설명하면, 방열기(12)는, LED 모듈(10')에 볼트와 같은 결합수단에 의해 결합되는 반원기둥 형상의 제1방열부(12a)와, 일측이 밀폐된 원기둥 형상의 제2방열부(12c)로 구성되는데, 제2방열부(12c)는 밀폐된 측은 제1방열부(12a)에 볼트 등 결합수단에 의해 결합되고, 타측(밀폐된 측의 반대측)으로는 소켓부(14)가 결합된다. 제1방열부(12a)는, LED 모듈(10')이 결합되는 반원기둥의 평판부에는 LED에서 발생되는 열을 방출시키기 위하여 다수의 방열구멍(12b)이 형성되고, 반원기둥의 구면부에는 일측 단부(端部)가 개방되고 내부와 외부로 다수의 방열핀이 형성되며, 방열효과를 높이기 위하여 구 면부에는 길이방향으로 3∼5개의 슬릿을 형성하여 구면부를 분할할 수도 있다. 또한 제2방열부(12c)는 일측이 밀폐된 원기둥 형상인데, 외측으로는 다수의 방열핀이 형성되고, 상기 제2방열부(12c)는 제1방열부(12a)보다 길이를 짧게 형성한다.Referring to the radiator 12 of the first embodiment shown in Figs. 2 and 3, the radiator 12 is a semi-cylindrical first radiator coupled to the LED module 10 'by a coupling means such as a bolt. 12a and a cylindrical heat-dissipating portion 12c having one side closed, the second heat dissipating portion 12c being coupled to the first heat dissipating portion 12a by a bolt or other coupling means. On the other side (opposite side of the sealed side), the socket portion 14 is coupled. In the first heat dissipation part 12a, a plurality of heat dissipation holes 12b are formed in the flat part of the semi-cylindrical column to which the LED module 10 'is coupled, and the heat dissipation holes 12b are formed in the spherical part of the semi-cylinder. One side end is opened and a plurality of heat dissipation fins are formed inside and outside, and in order to increase the heat dissipation effect, the spherical part may be divided by forming three to five slits in the longitudinal direction. In addition, the second heat dissipation part 12c has a cylindrical shape in which one side is sealed, and a plurality of heat dissipation fins are formed on the outside, and the second heat dissipation part 12c has a shorter length than the first heat dissipation part 12a.

본 발명에 따른 LED 램프는, 가로등에 설치된 LED 램프에 빗물이나 기타 이물질이 들어가는 것을 방지하기 위한 별도의 커버를 설치하지 않는 것이기 때문에 누수가 발생하여 LED 램프에 물 또는 습기 들어가거나 이물질이 들어가지 않도록 하기 위하여 LED 모듈(10')과 방열기의 제1방열부(12a) 사이에는 실리콘 등으로 된 밀봉가스켓(11)을 더 구비하는 것이 바람직하다.Since the LED lamp according to the present invention does not provide a separate cover to prevent rainwater or other foreign matter from entering the LED lamp installed in the street lamp, water leakage may occur so that water or moisture does not enter the LED lamp. In order to achieve this, it is preferable to further include a sealing gasket 11 made of silicon or the like between the LED module 10 'and the first heat dissipation part 12a of the radiator.

소켓부(14)에는 외부 전원을 받아 LED 모듈(10')에 전원을 공급해주는 전원부(13)가 내장되어 있는데, 전원부(13)에는 AC를 DC로 변환해주는 콘버터와 안정기도 포함되어 있고, 이와 같은 각 부품의 기술은 이 기술분야에서 공지되어 있으므로 상세한 설명은 생략한다. 이와 같이 소켓부를 통해 전원을 공급받기 때문에 기존에 설치되어 사용되고 있는 고압수은등, 형광등, 나트륨등, 메탈할라이트 램프를 빼내고 본 발명의 LED 램프를 교체하여 기존 시설을 그대로 사용하면 된다. 만일 안정기 등이 가로등 전주에 내장된 시설이라면 전주에 내장된 안정기 등의 부품을 제거한 후 램프만 교체하면 될 것이다.The socket 14 has a built-in power supply unit 13 for receiving external power to supply power to the LED module 10 '. The power supply unit 13 includes a converter and a ballast for converting AC into DC. Descriptions of the same parts are well known in the art, and thus detailed descriptions are omitted. Thus, since the power is supplied through the socket part, the high-pressure mercury lamp, fluorescent lamp, sodium lamp, and metal halide lamp that are installed and used in the past may be removed, and the existing lamp may be used as it is by replacing the LED lamp of the present invention. If the ballast is a built-in lamppost, the lamp will be replaced only after removing the ballast built into the pole.

또한 LED 모듈(10')은 PCB 기판의 저면에 전원 공급 및 제어 신호 전달을 위 한 패턴이 각각 형성되고 저항이 배치되며, RGB(Red, Green, Blue)의 색상을 갖는 LED가 순차적으로 일렬로 상면에 실장되는데, LED를 일정 그룹별로 점등을 제어하도록 복수의 컨트롤 IC, 콘버터나 안정기 등을 실장시킬 수도 있다.In addition, the LED module 10 'is formed with patterns for power supply and control signal transmission, resistors are disposed on the bottom surface of the PCB, and LEDs having RGB (Red, Green, Blue) colors are sequentially lined up. Mounted on the upper surface, a plurality of control ICs, converters, ballasts, and the like may be mounted to control the lighting of LEDs according to a predetermined group.

도 4와 5는 제2실시예를 도시한 것인데, 제2실시예는 LED모듈과 집광렌즈가 일체로 형성된 렌즈모듈(20)이 방열기(22)의 하부에 각각 결합되고, 2∼6개의 방열기(22)를 케이스(22b)에 수용하여 구성되며, 소켓을 통해 전원을 공급받는 것이 아니고, 전원선이 접촉단자를 통해 전원판(23)에 직접 연결되는 형태이다.4 and 5 illustrate a second embodiment, in which the lens module 20 in which the LED module and the condenser lens are integrally coupled to the lower part of the radiator 22, respectively, has two to six radiators. It is configured to accommodate the 22 in the case 22b, not to receive power through the socket, but to connect the power line directly to the power plate 23 through the contact terminal.

방열기(22)의 구성을 설명하면, 방열기의 상부에는 방열핀(22a)이 형성되고 하부에는 LED모듈과 집광렌즈가 일체로 형성된 렌즈모듈(20)이 결합되며, 상부와 하부 사이에는 공간부가 형성되어 있으며, 방열기(22)는 알루미늄과 같이 가벼우면서도 열전달효율이 우수한 재질을 사용하는 것이 바람직하다.Referring to the configuration of the radiator 22, the radiating fin 22a is formed on the upper portion of the radiator, and the lens module 20 having the LED module and the condenser lens are integrally coupled to the lower portion, and a space portion is formed between the upper portion and the lower portion.
