본 발명에 따른 발광다이오드램프(1)는 전원을 공급하면 인쇄회로기판(3) 위에 일렬로 배열된 다수개의 고휘도 발광다이오드(4)에서 밝고 직진성이 강한 빛이 발생하게 되는데 이 빛은 확산 광매체(5)를 통해 굴절되어 확산된다. 상기 확산 광매체(5)를 투과한 빛은 확산 광매체(5)의 상부에 일정간격 이격된 상태로 설치되어 있는 오목반사경(6)을 통해 아래쪽으로 1차 반사되고 이 빛은 다시 몸체(2)의 좌우 양측 상부에 설치되어 있는 접시형상으로 라운드진 반사판(7a)(7b)에 의해 위쪽으로 2차 반사되어 일정각도로 퍼지면서 밝은 빛이 투과창(8a)(8b)을 통하여 투과하게 된다. When the light emitting diode lamp 1 according to the present invention is supplied with power, a bright and strong light is generated in a plurality of high brightness light emitting diodes 4 arranged in a row on the printed circuit board 3. It is refracted and diffused through (5). The light transmitted through the diffused optical medium 5 is primarily reflected downward through the concave reflector 6 which is installed at a predetermined interval on the upper portion of the diffused optical medium 5, and the light is again reflected in the body 2. Is reflected by the rounded reflecting plates 7a and 7b in the shape of a plate provided on the upper left and right sides, and spreads at a predetermined angle, and bright light is transmitted through the transmission windows 8a and 8b. .

한편, 상기 고휘도 발광다이오드(4)는 빛이 발생하면서 열이 방출되는데 인쇄회로기판(3)의 하면부에 위치된 방열판(9)은 고휘도 발광다이오드(4)에서 발생하는 열을 외부로 방출시켜 자연 냉각되도록 되어 있다. On the other hand, the high brightness LED 4 emits heat as light is generated, and the heat sink 9 located on the lower surface of the printed circuit board 3 emits heat generated from the high brightness LED 4 to the outside. It is intended to cool naturally.
