Description

ＬＥＤ 매입 조명등 고정구조{Fixing Structure of Built in type LED Lighting}Fixing Structure of Built in type LED Lighting}

본 발명은 LED 매입 조명등 고정구조에 관한 것으로, 보다 상세하게는 LED의 조명을 반사되도록 하는 리플렉터의 고정을 위한 판스프링의 장착을 용이하게 하기 위한 LED 매입 조명등 고정구조에 관한 것이다. The present invention relates to an LED recessed lamp fixing structure, and more particularly to an LED recessed lamp fixing structure for facilitating the mounting of the leaf spring for fixing the reflector to reflect the illumination of the LED.

LED(Light Emitting Diode)는 P형과 N형 반도체의 접합구조를 가지고, 전력을 인가하면 전자와 정공의 결합으로 반도체의 밴드갭(bandgap)에 해당하는 에너지의 빛을 방출하는 광전자 소자이며, 반응 시간이 일반 전구에 비하여 빠르고, 소비전력이 일반전구에 비해 20%수준으로 낮아 고효율의 조명수단으로 널리 사용되고 있다.LED (Light Emitting Diode) is an optoelectronic device that has a junction structure of P-type and N-type semiconductors and emits light of energy corresponding to the bandgap of the semiconductor by combining electrons and holes when electric power is applied. Compared to general bulbs, time is faster and power consumption is 20% lower than general bulbs.

특히, 고출력 LED가 조명등으로 사용되는 경우에는 LED 모듈에서 많은 열을 발생시키게 되므로 이 발생된 열을 방출하기 위한 수단을 필요로 한다. In particular, when a high-power LED is used as a lamp, a large amount of heat is generated in the LED module, and thus a means for dissipating the generated heat is required.

종래의 조명등은 LED 모듈과 히트싱크를 부착한 패키지로 제작되고 있다. 이러한 히트싱크는 LED 모듈로부터 발생된 열을 흡수하여 공기와의 접촉으로 방열하게 되는 형태를 취한다. Conventional lamps are manufactured in packages with LED modules and heat sinks. The heat sink takes the form of absorbing heat generated from the LED module and radiating heat by contact with air.

LED 매입 조명등의 경우에는 매입된 LED 모듈에 구비된 LED의 조명을 반사하기 위한 리플렉터(reflector)를 필요로 하며, 이 리플렉터는 히트싱크에 삽입고정되게 된다. In the case of the LED embedded lamp, a reflector for reflecting the illumination of the LED included in the embedded LED module is required, and the reflector is inserted into and fixed to the heat sink.

이때, 리플렉터를 히트싱크에 고정하기 위하여 삽입된 리플렉터를 탄성력에 의해 고정시키는 판스프링이 히트싱크 또는 리플렉터에 장착되게 된다. At this time, the plate spring for fixing the reflector inserted by the elastic force to fix the reflector to the heat sink is mounted on the heat sink or the reflector.

종래의 판스프링 장착방법은 V자형 또는 U자형으로 된 판스프링의 중간부위를 히트싱크 또는 리플렉터에 리벳팅하여 장착하는 방법을 사용하였다. Conventional leaf spring mounting method used a method of riveting the middle portion of the V-shaped or U-shaped leaf spring to the heat sink or reflector.

따라서, 리벳팅을 하기 위한 리벳 재료를 필요로 하므로 재료비용이 많이 소요되며, 리벳팅하기 위한 많은 인력을 필요로 하며 리벳팅 작업완료후 에는 판스프링의 고정불량을 확인하는 작업을 수행하여야 하므로 작업공정이 복잡한 문제점이 있었다. 따라서, 리플렉터를 고정하기 위한 판스프링의 장착작업을 용이하도록 하기 위한 대책마련이 시급한 실정이다.

At least two grooves 30 are formed at a lower portion of the heat sink 10 side plate 12 at a predetermined angle with respect to the upper plate 13. The figure shows that four formed at an angle of 90 degrees. As shown in FIG. 3, the grooves 30 are formed in a pair with a step 31 formed on the upper side thereof and symmetrically. The leaf spring 40 is inserted into and fixed to the groove 30.

In order to insert the leaf spring 40 into the groove 30, an external force is applied to the branch 41 to narrow the width as shown in FIG. 2 so that the leaf spring 40 is inserted into the groove 30. When the external force is removed after the leaf spring 40 is inserted, the leaf spring 40 is returned to its original state by the restoring force of the leaf spring 40 and caught by the step 31 in the locking groove 42 as shown in FIGS. 3 to 5. It will be fixed.

또한, 판스프링 끼움 작업 후에 판스프링의 복원력에 의해 복원되면서 상기 걸림홈(42)에 상기 홈(30)의 상기 단차(31)가 걸리게 되므로 판스프링(40)을 별도로 고정하는 작업을 필요로 하지 않는다. In addition, since the step 31 of the groove 30 is caught by the restoring force of the leaf spring after the leaf spring fitting operation, the fixing of the leaf spring 40 is not necessary. Do not.

이와 같이 본 발명은 리플렉터를 고정하는 판스프링(40)을 상기 히트싱크(10)에 고정하게 될 때 판스프링(40)에 외력을 가하고 판스프링(40)의 가지(41)를 홈(30)에 간단하게 끼우는 작업만으로 고정이 되게 되므로 판스프링의 장착작업이 용이한 장점이 있다. As described above, when the leaf spring 40 fixing the reflector is fixed to the heat sink 10, an external force is applied to the leaf spring 40 and the branches 41 of the leaf spring 40 are grooved 30. Since it is fixed by simply inserting the work into the plate spring has the advantage of easy mounting work.

상기 리플렉터(50)는 상기 LED(22)의 조명을 반사하며 상기 히트싱크(10)의 개구부(11)에 삽입되어 상기 히트싱크(10)에 결합되고 상기 판스프링(40)의 탄성력에 의해 고정된다. The reflector 50 reflects the illumination of the LED 22 and is inserted into the opening 11 of the heat sink 10 to be coupled to the heat sink 10 and fixed by the elastic force of the leaf spring 40. do.

상기 리플렉터(50)는 상기 판스프링(40)의 탄성력에 의해 고정될 수 있으나, 리플렉터(50)의 고정력을 배가시키기 위해서는 상기 판스프링(40)의 가지(41) 상부 단부 부위에 상기 히트싱크(10)에 삽입된 상기 리플렉터(50)를 지지하여 고정하도록 가지(41)의 삽입방향 내측으로 경사지게 절곡된 고정용 절곡부(43)가 형성되는 것이 바람직하다(도 2 참조). The reflector 50 may be fixed by the elastic force of the leaf spring 40. However, in order to double the fixing force of the reflector 50, the heat sinks are formed at the upper end portions of the branches 41 of the leaf spring 40. It is preferable that the fixing bent portion 43 bent inclined inwardly in the insertion direction of the branch 41 to support and fix the reflector 50 inserted in the 10 (see Fig. 2).

이에 따라 상기 고정용 절곡부(43)의 단부가 삽입된 리플렉터(50)의 외면과 접촉하게 됨으로써 리플렉터(50)가 하부로 이탈되는 것을 방지할 수 있게 됨으로써 리플렉터(50)의 고정력을 크게 할 수 있게 된다. Accordingly, the end of the fixing bent portion 43 comes into contact with the outer surface of the inserted reflector 50, thereby preventing the reflector 50 from being separated downward, thereby increasing the fixing force of the reflector 50. Will be.

아울러, 상기 판스프링(40)을 고정하기 위해서 상기 홈(30)에 상기 판스프링(40)의 가지(41)를 삽입하게 되는데, 상기 판스프링(40)의 가지를 상기 홈(30)에 삽입하는 것을 용이하게 하기 위해 상기 판스프링(40)의 가지(41) 하부 단부 부위에 상기 판스프링(40)의 가지(41)가 상기 홈(30)으로의 삽입이 용이하도록 가지(41)의 삽입방향 외측으로 경사지게 절곡된 삽입용 절곡부(44)가 형성되는 것이 바람직하다(도 2 참조). In addition, the branch 41 of the leaf spring 40 is inserted into the groove 30 in order to fix the leaf spring 40, and the branch of the leaf spring 40 is inserted into the groove 30. The branch 41 of the leaf spring 40 is inserted into the groove 30 so that the branch 41 of the leaf spring 40 can be easily inserted into the groove 30 at the lower end of the branch 41 of the leaf spring 40. It is preferable that the insertion bent portion 44 bent obliquely in the direction is formed (see Fig. 2).

이에 따라 상기 가지(41)의 하부 단부 부위에 삽입용 절곡부(44)를 형성하게 됨에 따라 상기 가지(41)의 수직높이가 상기 홈(30)의 높이보다 작게 됨으로써 상기 가지(41)를 상기 홈(30)으로의 삽입을 용이하게 할 수 있게 된다. Accordingly, as the insertion bent portion 44 is formed at the lower end portion of the branch 41, the vertical height of the branch 41 is smaller than the height of the groove 30 so that the branch 41 is formed. The insertion into the groove 30 can be facilitated.
