Description

냉각 엘이디등Cooling LED light
본 발명은 냉각 엘이디등(LED 燈)에 관한 것으로서, 더욱 상세히는 내부에 냉각수가 순환하도록 구성하고, 상기 냉각수는 유입된 공기에 의해서 열교환 되도록 구성한, 냉각 엘이디등에 관한 것이다.The present invention relates to a cooling LED lamp (LED,), and more particularly to the cooling water circulated inside, and the cooling water is configured to heat exchange by the introduced air, the cooling LED lamp.
엘이디등(LED 燈)은 엘이디(LED; Light-Emitting Diode, 발광다이오드)를 사용하여 제작한 등(燈, light)으로서, 형광등이나 백열전구와 같은 종래의 조명등에 비해서 효율이 우수하기 때문에 상기 종래의 조명등은 엘이디등으로 대체되고 있는 추세에 있다.LED lamp is a light produced using LED (Light-Emitting Diode, LED), the efficiency is superior to conventional lighting such as fluorescent lamps and incandescent lamps, Lamps are being replaced by LEDs.
이렇게 효율이 우수한 엘이디도 전기의 인가로 인해서 저항열이 발생하게 되는데, 이 저항열은 엘이디의 수명을 단축시킬 뿐만 아니라, 엘이디와 기판을 연결하는 땜납을 녹이게 되어, 엘이디가 기판에서 이탈되도록 하는 문제점이 있었다.This highly efficient LED also generates heat of resistance due to the application of electricity, which not only shortens the life of the LED, but also melts the solder that connects the LED to the substrate, causing the LED to be released from the substrate. There was a problem.
이러한 문제점을 해결하기 위해 자체 냉각이 가능한 냉각 엘이디등(1)이 한국 특허등록 10-0854084호로 등록된 바 있다.In order to solve this problem, a cooling LED lamp (1) capable of self cooling has been registered in Korean Patent Registration No. 10-0854084.
상기 냉각 엘이디등(1)의 구성을 도 1을 통하여 살펴보면 다음과 같다.Looking at the configuration of the cooling LED lamp (1) as follows.
하바으로 개방된 용기 형상으로서 외측면에 방열핀(13)이 다수 개 형성된 후드(10)가 구성되고, 상기 후드(10)의 하방에는 투명 또는 반투명 재질의 투광판(20)이 커버된다. 그리고, 상기 투광판(20)의 상부에 배치되어 후드(10)에 고정되고 내부에 냉각수(R)의 수용이 가능한 판상의 엘이디 고정구(40)가 구성된다. 그리고, 상기 엘이디 고정구(40)의 하면에는 엘이디(30)가 장착되어 구성된다. 또한, 상기 후드(10) 내부의 상부에는 냉각수(R)를 수용할 수 있는 냉각수함(50)이 구획되어 구성된다. 그리고, 상기 냉각수함(50)의 내부에는 냉각수(R)를 순환시키는 순환펌프(60)가 내장되어 구성된다. 또한, 상기 냉각수함(50)과 엘이디 고정구(40)를 연결하는 파이프(70)가 구성된다.A hood 10 having a plurality of heat dissipation fins 13 formed on an outer surface of the container shape opened to the bottom is formed, and a light-transmitting plate 20 of transparent or translucent material is covered under the hood 10. In addition, a plate-shaped LED fixture 40 is disposed on the floodlight panel 20 and fixed to the hood 10 and accommodates the cooling water R therein. Then, the LED 30 is mounted on the lower surface of the LED fixture 40 is configured. In addition, the upper portion of the inside of the hood 10, the cooling water box 50 that can accommodate the cooling water (R) is partitioned. In addition, the cooling water box 50 has a built-in circulation pump 60 for circulating the cooling water (R). In addition, the pipe 70 is connected to the cooling water box 50 and the LED fixture 40.
상기 구성에 의한 냉각 엘이디등(1)의 작동 과정을 살펴보면 다음과 같다.Looking at the operation of the cooling LED lamp 1 by the above configuration.
먼저, 상기 냉각수함(50)에 냉각수(R)가 충전된 상태에서, 상기 엘이디(30)에 전기를 인가하여 빛을 조사(照射)하도록 한다. 그리고, 상기 순환펌프(60)에 전기를 인가시켜서 냉각수함(50) 내부에 수용된 냉각수(R)가 상기 파이프(70)를 통해서 엘이디 고정구(40)의 내부를 거쳐서 다시 복귀하도록 하는 순환 과정이 반복되도록 한다.First, in a state in which the cooling water R is filled in the cooling water box 50, electricity is applied to the LED 30 to emit light. Then, the circulation process is repeated by applying electricity to the circulation pump 60 so that the cooling water R accommodated in the cooling water box 50 returns back through the inside of the LED fixture 40 through the pipe 70. Be sure to
그러면, 상기 엘이디(30)에서 발생한 열은 엘이디 고정구(40)의 내부로 유입된 냉각수(R)에 의해 흡열된 후, 냉각수함(50)으로 복귀된다. 상기 냉각수함(50)으로 복귀된 냉각수(R)는 상기 후드(10)의 외측면에 구성된 방열핀(13)을 통해서 외부로 열을 발산하게 된다.Then, the heat generated by the LED 30 is absorbed by the cooling water (R) introduced into the interior of the LED fixture 40, and then returned to the cooling water box (50). The coolant R returned to the coolant box 50 dissipates heat to the outside through the heat dissipation fin 13 formed on the outer surface of the hood 10.
상기 배경기술에 의하면, 상기 엘이디 고정구 내부에서 엘이디에 의해 데워진 냉각수가 냉각수함으로 복귀된 후, 다시 엘이디 고정구로 유입되는 사이클이 반복하게 된다. 이때, 냉각수는 엘이디에 의해 지속적으로 데워지게 되어, 더 이상 엘이디에 발생한 고열을 외부로 방열할 수 없는 문제점이 있었다. 즉, 상기 냉각수함에서 효율적으로 방열할 수 없으므로 엘이디의 열이 계속 축열되는 문제점이 있었다. 물론, 상기 방열핀이 구성되어 있지만, 방열핀 쪽의 최외곽에 있는 냉각수의 열만 소량 방열될 뿐, 냉각수함에 수용된 전체 냉각수의 열을 효율적으로 방열시킬 수 없는 문제점이 있었다.According to the background art, after the coolant warmed by the LED inside the LED fixture is returned to the coolant, the cycle of inflowing to the LED fixture again is repeated. At this time, the cooling water is continuously heated by the LED, there is a problem that can no longer radiate heat generated outside the LED to the outside. That is, since the heat dissipation in the cooling water box can not be efficiently radiated, there is a problem that the heat of the LED is continuously stored. Of course, although the heat dissipation fin is configured, only a small amount of heat of the coolant at the outermost side of the heat dissipation fin is radiated, and there is a problem in that the heat of the entire coolant contained in the coolant can not be effectively dissipated.
본 발명에 의한 냉각 엘이디등은, 하방으로 개방된 용기 형상의 후드와, 상기 후드의 하방을 가리도록 상기 후드에 고정되고 하면에 엘이디가 장착되는 커버플레이트와, 상기 커버플레이트의 상면에 구성되어 상기 후드의 내부에 위치하고 냉각수를 수용하는 공간이 내부에 형성된 워터재킷과, 상기 워터재킷의 하면에 장착되는 엘이디와, 상기 워터재킷의 상면에 부착되어 상기 후드에 수용되고 내부에 공간이 형성되어 냉각수가 수용된 다수 개의 냉각키트와, 상기 후드에 관통되어 외부의 공기가 유입된 후 배출되는 통공을 포함하여 구성된다.The cooling LED according to the present invention includes a container-shaped hood opened downward, a cover plate fixed to the hood so as to cover the bottom of the hood, and an LED mounted on a lower surface thereof, and an upper surface of the cover plate. A water jacket formed inside the hood and containing a coolant therein, an LED mounted on the bottom surface of the water jacket, and an upper surface of the water jacket attached to the hood to form a space therein to form a cooling water. It includes a plurality of cooling kits accommodated, and through-holes through which the outside air is introduced and discharged through the hood.
또한, 상기 워터재킷에 장착되어 상기 워터재킷 내부의 냉각수를 순환시키는 순환장치를 포함하여 구성된다.In addition, the water jacket is configured to include a circulation device for circulating the cooling water in the water jacket.
또한, 상기 순환장치는, 상기 워터재킷에 장착되어 냉각수를 순환시키는 펌프를 포함하여 구성된다.In addition, the circulation device includes a pump mounted to the water jacket to circulate the cooling water.
또한, 상기 순환장치는, 상기 워터재킷의 상면에 고정된 모터와, 상기 모터에 연결되어 상기 워터재킷의 내부에 수용된 팬(fan)을 포함하여 구성된다.The circulation device may include a motor fixed to an upper surface of the water jacket, and a fan connected to the motor and accommodated in the water jacket.
또한, 상기 냉각키트는 상방으로 적층하도록 구성된다.In addition, the cooling kit is configured to be stacked upwards.
본 발명에 의한 냉각 엘이디등은, 워터재킷에 장착된 순환장치에 의해서 신속하게 엘이디의 열이 냉각키트로 전달된다. 또한, 상기 냉각키트가 다수 개 구성되므로 통공으로 유입된 공기에 접하는 면적을 넓힐 수 있으므로 효율적으로 방열시킬 수 있다. 즉, 본 발명은 엘이디의 열을 적극적으로 후드의 외부로 방출시키는 열펌프의 역할을 하게 된다. 따라서, 효율적으로 엘이디를 냉각시킬 수 있으므로 엘이디의 수명을 연장시킬 수 있고, 엘이디를 기판에 밀착시키는 땜납이 녹아서 엘이디가 이탈되는 현상을 예방할 수 있는 효과가 있다.In the cooling LED according to the present invention, the heat of the LED is quickly transferred to the cooling kit by a circulation device mounted on the water jacket. In addition, since the cooling kit is configured in plural, the area in contact with the air introduced into the through hole can be widened, so that the heat radiation can be efficiently conducted. That is, the present invention serves as a heat pump to actively discharge the heat of the LED to the outside of the hood. Therefore, since the LED can be efficiently cooled, the life of the LED can be extended, and the solder that adheres the LED to the substrate is melted, thereby preventing the phenomenon of the LED from falling off.
또한, 본 발명은 상기 냉각키트를 다층으로 적층할 수 있으므로 방열면적을 확장시킬 수 있는 효과가 있다.In addition, the present invention can be laminated in a multi-layered cooling kit has the effect of expanding the heat dissipation area.

In addition, the upper surface of the cover plate 115 is configured with a pair of protrusions 116 so that the lower end of the cooling kit 160 is fitted.

It is configured to be.
상기 워터재킷(120)과 냉각키트(160)의 내부에는 냉각수(R)로서 물도 가능하지만, 에틸렌글리콜처럼 겨울에 동결되지 않고 부식성이 없으며, 열을 흡수하고 방열하는 효율이 뛰어난 전용 냉각수를 충전하여 구성하는 것이 바람직하다. 상기 에틸렌글리콜을 물과 혼합하여 구성할 수도 있다.Water inside the water jacket 120 and the cooling kit 160 may be water as the cooling water R, but it is not frozen in the winter like ethylene glycol, does not freeze in the winter, and is filled with dedicated cooling water having excellent efficiency of absorbing heat and radiating heat. It is preferable to construct. The said ethylene glycol can also be mixed with water and comprised.
상기 구성에 의한 본 발명의 작동례를 살펴보면 다음과 같다.Looking at the operation example of the present invention by the above configuration.
먼저, 상기 엘이디(140)에 전기를 인가한 후, 상기 순환장치(170)에 전기를 인가하여 구동시킨다. 상기 순환장치(170)가 펌프(171)일 때에는 냉각수(R)를 흡수하여 상기 관(173)을 통해서 배출하게 되는데, 관(173)이 휘어져 있으므로 도 6에서처럼 회전하게 된다. 또는, 순환장치가(170)가 모터(175)와 팬(177)으로 구성되었을 때에는 상기 모터(175)의 구동으로 팬(177)이 회전하므로 냉각수(R)를 회전시킬 수 있다.First, after the electricity is applied to the LED 140, it is driven by applying electricity to the circulator 170. When the circulator 170 is the pump 171, the cooling water R is absorbed and discharged through the tube 173, but the tube 173 is bent and rotated as shown in FIG. 6. Alternatively, when the circulation device 170 includes the motor 175 and the fan 177, the cooling water R may be rotated because the fan 177 is rotated by the driving of the motor 175.
따라서, 상기 엘이디(140)로부터 발생한 열은 커버플레이트(115)를 통해서 워터재킷(120)에 수용된 냉각수(R)로 전달된다. 이때, 상기 순환장치(170)가 없다면 맨 아래에서 상방으로 순차적으로 냉각수(R)가 데워지므로 상기 냉각키트(160)까지 열을 전달하는데 많은 시간이 소요된다. 그러나, 상기 순환장치(170)로 인해서 냉각수(R)가 회전하면서 혼합되므로 신속하게 냉각키트(160)로 열을 전달할 수 있는 이점이 있다.Therefore, heat generated from the LED 140 is transferred to the coolant R accommodated in the water jacket 120 through the cover plate 115. At this time, if there is no circulation device 170, since the cooling water (R) is sequentially heated from the bottom upward, it takes a lot of time to transfer heat to the cooling kit (160). However, since the coolant R is mixed while rotating due to the circulator 170, there is an advantage in that heat can be quickly transferred to the cooling kit 160.
이렇게 해서 워터재킷(120)에 전달된 열은 상기 냉각키트(160)에 수용된 냉각수(R)로 전달된다. 이때, 상기 후드(110)의 통공(113)을 통해서 유입된 공기는 냉각키트(160)의 사이로 통과하면서 열을 흡수한 후, 다시 통공(113)을 통해서 배출된다. 즉, 상기 워터재킷(120)과 냉각키트(160) 그리고 통공(113)은 엘이디(140)에서 발생한 열을 외부로 적극적으로 배출시키는 열펌프의 역할을 하게 된다. 따라서, 상기 엘이디(140)의 수명이 연장되고, 엘이디(140)를 부착시키는 땜납이 녹아서 엘이디(140)가 이탈되는 현상을 방지할 수 있는 이점이 있다.In this way, the heat transferred to the water jacket 120 is transferred to the cooling water (R) accommodated in the cooling kit (160). At this time, the air introduced through the through hole 113 of the hood 110 absorbs heat while passing through the cooling kit 160, and is then discharged through the through hole 113 again. That is, the water jacket 120, the cooling kit 160 and the through hole 113 serves as a heat pump actively discharging the heat generated from the LED 140 to the outside. Therefore, the life of the LED 140 is extended, there is an advantage that can prevent the phenomenon that the LED 140 is detached by melting the solder to attach the LED 140.
본 발명은 엘이디의 열을 적극적으로 후드의 외부로 방출시켜 효율적으로 엘이디를 냉각시킬 수 있으므로 엘이디의 수명을 연장시킬 수 있고, 엘이디를 기판에 밀착시키는 땜납이 녹아서 엘이디가 이탈되는 현상을 예방할 수 있고, 방열면적을 확장시킬 수 있어 냉각성이 우수한 엘이디등을 제공할 수 있다.According to the present invention, since the heat of the LED can be actively released to the outside of the hood to efficiently cool the LED, the life of the LED can be extended, and the solder that adheres the LED to the substrate is melted to prevent the phenomenon of the LED from falling off. In addition, the heat dissipation area can be expanded to provide an LED having excellent cooling ability.
