The present invention relates to an LED lamp for a street lamp having a waterproof function, and more particularly, is formed in a spherical shape, and a cap having heat dissipation holes at the upper and lower ends of a cover to which a heat sink equipped with a plurality of LEDs is coupled. By combining, the LED can be prevented from being damaged by heat by the external air flowing into the heat sink through the flow hole of the cap to the maximum, and is coupled between the flow hole formed in the cap and the cover and the heat sink. It prevents the LED from being damaged due to the short circuit by blocking the inflow of water into the inside of the cover due to the gasket, and the waterproof function that makes it easy to install the LED lamp on the electric pole pipe due to the spherical LED lamp. It is about LED lamp for street lamp which we have.

일반적으로 가로등이란 도로변에 설치되어 야간 조명등으로 사용되는 것을 말하는 것이다.In general, street lamps are those that are installed near the road and used as night lights.

종래의 가로등은 밝은 빛을 내기 위하여 할로겐등, 메탈램프, 나트륨램프, 수은등을 사용하고 있으며, 광원이 케이스 내부에 완전히 내장된 구성이며, 내부열이 높고 자연환경에 많은 오염을 가져왔다.Conventional street lamps use halogen lamps, metal lamps, sodium lamps, mercury lamps to emit bright light, and the light source is completely built in the case, and the internal heat is high and a lot of pollution is caused to the natural environment.

따라서 이러한 문제점을 해결하고자 LED를 광원으로 사용하는 LED램프를 전주와 연결된 전주파이프에 설치하게 되었다.Therefore, to solve this problem, the LED lamp using the LED as a light source was installed in the pole pipe connected to the pole.

그러나 종래의 LED램프의 문제점은, LED가 장착된 LED램프를 전주파이프에 직접 연결을 하므로서, 상기 LED램프의 설치가 용이하지 못함은 물론 유지 보수 비용이 증가 되는 문제점이 발생하게 되었다.However, the problem of the conventional LED lamp, the LED lamp equipped with the LED is directly connected to the electric pole pipe, the installation of the LED lamp is not easy, as well as the problem that the maintenance cost increases.

즉, 다수의 LED가 장착되는 LED케이스에 관통홈을 형성하고, 상기 관통홈의 내측에 끼워지도록 전주파이프에 LED케이스를 끼워 결합하므로서, 상기 LED가 장착된 LED케이스의 설치가 용이하지 못하는 문제점이 발생하게 되었다.That is, by forming a through groove in the LED case in which a plurality of LEDs are mounted, by inserting the LED case in the pole pipe to be fitted inside the through groove, the installation of the LED case with the LED is not easy It happened.

또한, LED램프의 LED가 파손 및 수명이 다하여 LED램프를 교체 시에도 전주파이프에 직접 결합 된 상기 LED램프를 분리해야만 하기 때문에 LED램프의 교체 시간 및 비용이 증가 되는 문제점이 발생하게 되었다.
In addition, since the LED lamp of the LED lamp is damaged and reached the end of life, there is a problem that the replacement time and cost of the LED lamp is increased because the LED lamp directly connected to the electric pole pipe must be removed even when the LED lamp is replaced.

따라서 상기 문제점을 해결하기 위하여 본 발명은 다수의 LED가 장착된 히트싱크가 내부에 장착된 구 형태의 커버의 상,하단에 각각 방열홀이 구비된 캡을 결합하므로서, 상기 유동홀을 따라 입,출입 되는 외부 공기로 인해 LED가 열에 의해 파손되는 것을 최대한으로 방지할 수 있으며, 상기 캡에 형성된 유동홀과 LED램프에 결합 되는 가스켓으로 인하여 커버의 내측으로 물이 유입되는 것을 최대한으로 방지하여 누전으로 인해 LED가 파손되는 것을 방지할 수 있으며, 구 형태로 LED램프를 제작하기 때문에 상,하 구분없이 전주파이프에 LED램프를 설치할 수 있으며, 또한, LED램프에 다공홀이 구비된 고정파이프를 결합한 상태에서 고정파이프를 이용하여 전주파이프에 LED램프를 장착하기 때문에 LED램프의 설치 시간 및 유지 보수 시간을 줄일 수 있도록 한 방수기능을 구비한 가로등용 엘이디램프를 제공함을 목적으로 한다.
Therefore, in order to solve the above problems, the present invention combines a cap having heat dissipation holes at the upper and lower ends of a spherical cover having a plurality of heat sinks equipped with LEDs, respectively. The LED is prevented from being damaged by heat due to the outside air entering and exiting, and the gasket coupled to the flow hole formed in the cap and the LED lamp prevents water from entering the inside of the cover to the maximum as a short circuit. Due to this, the LED can be prevented from being damaged, and since the LED lamp is manufactured in the shape of a sphere, the LED lamp can be installed in the electric pole pipe without distinguishing the upper and lower sides.
