Description
본 발명은, 발광다이오드의 고정구조, 특히 차량용 램프장치에 적합한 발광다이오드의 고정구조에 관한 것이다.The present invention relates to a fixing structure of a light emitting diode, in particular to a fixing structure of a light emitting diode suitable for a vehicle lamp device.
차량용의 램프등에 사용되고 있는 발광다이오드로서는 일본 특개평 10-188614호 공보에 도시하는 바와 같이, 발광다이오드의 바닥면에 형성된 리드다리를, 램프에 설치된 프린트기판에 대하여, 납땜함으로써 고정하고 있다.As a light emitting diode used in a lamp for a vehicle, as shown in Japanese Patent Laid-Open No. 10-188614, a lead leg formed on the bottom surface of the light emitting diode is fixed by soldering to a printed board provided in the lamp.
그렇지만, 종래와 같이 프린트기판에 발광다이오드를 납땜하는 구조에서는, 발광다이오드의 광의 이용효율이 낮고, 필요한 밝기를 얻기 위하여 수많은 발광다이오드를 필요로 하고, 비용면에서 불리하다.However, in the structure in which the light emitting diodes are soldered to the printed circuit board as in the related art, the utilization efficiency of light of the light emitting diodes is low, and many light emitting diodes are required to obtain the required brightness, which is disadvantageous in terms of cost.
또, 발광다이오드의 리드다리를 1개씩 프린트기판에 납땜하기 때문에, 발광다이오드를 고정하는 작업이 번잡하고, 제조효율이 나쁘다. 또, 일단 고정된 후에 고쳐서 부착하는 작업도 곤란하다.In addition, since the lead legs of the light emitting diodes are soldered one by one to the printed circuit board, fixing the light emitting diodes is complicated and the manufacturing efficiency is poor. Moreover, it is also difficult to fix and attach once fixed.
본 발명은, 이와 같은 종래의 기술에 착안하여 이루어진 것이며, 광 이용효율이나 제조효율면에서 우수한 발광다이오드의 고정구조를 제공하는 것이다.The present invention has been made in view of such a conventional technology, and provides a fixing structure of a light emitting diode excellent in light utilization efficiency and manufacturing efficiency.

Next, the notch groove 13 of the metal plate 8 is set on each cord 2, and the cutout groove 13 is pushed on each cord 2 by pressing the surface portion 9 of the metal plate 8. Press in. Since the surface portion 9 exists around the light emitting diode 3, the surface portion 9 is used as a surface for pressing the surface portion 9 with a finger, and the press fitting operation is easy.
코드(2)에 대하여 절결홈(13)이 압입되면, 이 절결홈(13)이 코드(2)의 외피 (2b)를 잘라 끼워넣어 심선(2a)과 도통하기 때문에(도 4 참조), 이 절결홈(13)과 코드의 접합력에 의해, 발광다이오드(3)가 코드(2)에 대하여 고정된다. 또, 금속플레이트(8)를 통하여, 발광다이오드(3)와 코드(2)가 도통하는 상태도 얻게 된다. 코드(2)의 아래에 대좌(6)가 있기 때문에, 절결홈(13)의 압입을 확실히 행하게 된다. 또, 금속플레이트(8)의 다리부(10)는 서로 마주보는 벽(4)의 사이로 들어감과 동시에, 다리부(10)에 형성된 절기부(14)가 벽(4)에 탄성접합하고, 금속플레이트(8)의 안정된 상태가 얻어진다.When the notch groove 13 is press-fitted to the cord 2, the notch groove 13 cuts and inserts the sheath 2b of the cord 2 and conducts with the core wire 2a (see Fig. 4). The light emitting diodes 3 are fixed to the cords 2 by the bonding force between the cutout grooves 13 and the cords. In addition, a state in which the light emitting diodes 3 and the cords 2 conduct through the metal plate 8 is also obtained. Since the pedestal 6 is located under the cord 2, the notch groove 13 is press-fitted securely. In addition, the leg portion 10 of the metal plate 8 enters between the walls 4 facing each other, and the cutout portions 14 formed on the leg portion 10 are elastically bonded to the wall 4, and the metal A stable state of the plate 8 is obtained.
이와 같이, 절결홈(13)을 원터치로 코드(2)에 압입하는 것만으로, 발광다이오드(3)의 고정이 행해지기 때문에, 종래와 같은 납땜작업이 불필요하게 되고, 고정작업이 용이하며, 제조효율이 양호하고, 자동화도 가능하다. 또한 고쳐서 부착하기도 용이하다. 또, 고정된 발광다이오드(3)는 리드다리(15)가 4개이기 때문에, 고정후에 쓰러지기 어렵고, 발광다이오드(3)의 방향도 변화하기 어렵다. 또한, 1개의 발광다이오드(3)를 2개의 금속플레이트(8)로 고정하기 때문에, 1개의 금속플레이트(8)의 사이즈를 작게 할 수 있어, 금속플레이트(8)의 제조가 용이하다.As described above, since the light emitting diodes 3 are fixed by simply pressing the notch groove 13 into the cord 2 by one touch, the soldering work as in the prior art is unnecessary, and the fixing work is easy, The efficiency is good and automation is also possible. It is also easy to fix and attach. In addition, since the fixed light emitting diodes 3 have four lead legs 15, they are hard to fall down after being fixed, and the direction of the light emitting diodes 3 also hardly changes. In addition, since one light emitting diode 3 is fixed by two metal plates 8, the size of one metal plate 8 can be reduced, and the manufacture of the metal plate 8 is easy.
그리고, 고정된 발광다이오드(3)의 광은, 금속색이 행해진 금속플레이트(8)의 표면부(9)에 의해 확실히 반사되기 때문에, 발광다이오드(3) 개개의 광의 이용효율이 높다. 따라서 동등한 밝기를 얻는다 하더라도 종래보다도 발광다이오드(3)의 수량을 적게 할 수 있으며, 램프구조의 간략화 및 비용의 저감을 도모할 수 있다. 또, 2개의 금속플레이트(8)로 발광다이오드(3)를 고정하고 있는데, 2개의 금속플레이트(8)가 서로 근접해서 동일한 상태이기 때문에, 광의 이용효율이 향상된다. 또한, 발광다이오드(3)의 리드다리(15)가, 전열성이 높은 동제이기 때문에, 발광다이오드(3)의 발열은, 리드다리(15)를 통하여 금속플레이트(8)에 확실히 전해진다. 그리고, 그 열은 금속플레이트(8)의 넓은 표면부(9)에서 방열되기 때문에, 발광다이오드(3)의 방열성이 향상된다.Since the light of the fixed light emitting diode 3 is reliably reflected by the surface portion 9 of the metal plate 8 subjected to the metal color, the utilization efficiency of the light of each of the light emitting diodes 3 is high. Therefore, even if the same brightness is obtained, the quantity of the light emitting diodes 3 can be made smaller than before, and the lamp structure can be simplified and the cost can be reduced. In addition, although the light emitting diodes 3 are fixed by the two metal plates 8, since the two metal plates 8 are in the same state in close proximity to each other, the light utilization efficiency is improved. In addition, since the lead legs 15 of the light emitting diodes 3 are made of copper having high heat conductivity, the heat generated by the light emitting diodes 3 is reliably transmitted to the metal plate 8 through the lead legs 15. The heat is dissipated in the wide surface portion 9 of the metal plate 8, so that the heat dissipation of the light emitting diodes 3 is improved.
또한, 금속플레이트(8)의 표면부(9)에 각각 구멍부(11)가 1개씩 형성되어 있기 때문에, 만일 인접하는 금속플레이트(8)와의 사이의 코드(2)에 단선이 생겨도, 도 1에 도시하는 바와 같이, 점퍼선(16)의 양단부를 각 금속플레이트(8)의 구멍부에 대하여 작은 나사(17)로 고정하는 것으로 되어, 그 금속플레이트(8)끼리를 전기적으로 접속상태로 할 수 있다. 이와 같이 예측불허의 사태에 대한 대응책도 고려되어 있기 때문에 신뢰성이 높다.In addition, since one hole 11 is formed in each of the surface portions 9 of the metal plate 8, even if a wire break occurs in the cord 2 between the adjacent metal plates 8, FIG. As shown in Fig. 2, both ends of the jumper wires 16 are fixed with small screws 17 to the hole portions of the metal plates 8, and the metal plates 8 are electrically connected to each other. Can be. As such countermeasures against unforeseen circumstances are considered, they are highly reliable.
