이제 본 발명의 바람직한 실시예를 첨부한 도면을 참고로 하여 설명한다.Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

도 2에서 도 5를 참고, 본 발명의 실시예에 따른 엘이디램프(1000)는 그 내부에 엘이디소자가 배치되는 몸체부(500)를 가진다.2 to 5, the LED lamp 1000 according to the embodiment of the present invention has a body portion 500 in which the LED element is disposed therein.

도 2 및 도 3은 분해사시도를 보이며, 도 4는 분리된 부품의 단면도를 그리고 도 5는 결합단면도를 보인다.2 and 3 show an exploded perspective view, FIG. 4 shows a cross-sectional view of the separated component and FIG. 5 shows a combined cross section.

본 실시예에 따른 엘이디램프(1000)는 형광등 타입으로서 몸체부(500)는 원통형의 형상을 하고 있으며, 그 내부에 전원구동회로가 설치된 전원피시비(PCB)와 엘이디소자가 배치된 엘이디소자피시비(PCB)가 배치된다.LED lamp 1000 according to the present embodiment is a fluorescent lamp type body portion 500 has a cylindrical shape, there is a power supply circuit (PCB) and the LED element PCB (LED element) is arranged in which a power drive circuit is installed therein ( PCB) is placed.

이러한 몸체부(500)는 그 상부의 반원부(40)는 열전도플라스틱으로 이루어져 방열을 이룰 수 있으며, 그 하부의 반원부(60)는 투광을 이룰 수 있는 합성수지로 이루어져 빛이 투광될 수 있다. 이에 따라 상기 상부의 반원부(40)는 방열부를 이루고 하부의 반원부(60)는 투광부를 이룬다.The body portion 500 is a semi-circular portion 40 of the upper portion may be made of heat conducting plastic to achieve heat dissipation, the semi-circular portion 60 of the lower portion may be made of a synthetic resin that can be made to transmit light. Accordingly, the semi-circular portion 40 of the upper portion forms a heat dissipation portion, and the semi-circular portion 60 of the lower portion forms a light transmitting portion.

이러한 몸체부(500)는 일체로 이루어져 있다. 즉 본 발명에 따른 몸체부(500)는 종래와 같이 상기 방열부(40)와 투광부(60)가 각각 분리된 것을 결합한 것이 아니며, 본래 일체로 성형된다. 이러한 몸체부(500)의 구성은 이중압출을 통하여 달성 된다.This body portion 500 is made integrally. That is, the body portion 500 according to the present invention is not combined with each of the heat dissipating portion 40 and the light transmitting portion 60, as in the prior art, is formed inherently integrally. The configuration of such a body portion 500 is achieved through double extrusion.
