Description

분리형 ＬＥＤ 전구Detachable LED Bulb

본 발명은 LED 전구에 관한 것으로서, 보다 상세하게는 기존의 모듈 일체형 LED 전구보다 우수한 방열효과를 갖도록 구현할 수 있고, 각 모듈 간의 내구 수명 차이로 인한 경제적, 환경적인 폐해를 최소화할 수 있는 분리형 LED 전구에 관한 것이다.The present invention relates to an LED bulb, and more particularly, can be implemented to have a better heat dissipation effect than the conventional module-integrated LED bulb, and a separate type LED bulb that can minimize the economic and environmental damage due to the difference in endurance life between each module It is about.

일반적으로, LED(Light Emitting Diode)란 발광다이오드의 약자로서 빛을 발하는 반도체 소자를 말하여, 방출하는 빛의 색깔은 반도체 칩 구성원소의 배합에 따라 파장을 만들며, 이러한 파장이 빛의 색깔을 결정한다.In general, an LED (Light Emitting Diode) is an abbreviation of a light emitting diode and refers to a semiconductor device that emits light. The color of emitted light creates a wavelength depending on the composition of semiconductor chip components, and the wavelength determines the color of light. do.

이러한 LED를 사용하는 LED 전구는 열선(filament)을 가열하여 생기는 빛을 이용하는 기존의 일반 백열전구에 비하여 전력 소모가 1/5밖에 안되고, 반응시간은 1,000,000배나 빠르며, 수명은 반영구적인 장점을 가지기 때문에, 각종 적용 분야에 현저히 발달, 향상되어 정밀 반도체 장비 검사 기구, 자동차 계기판 등의 전자 표시판, 전광판, 산업기계 표시기 및 각종 교통 안전 신호등에 사용되고 있다.LED bulbs using these LEDs consume only 1/5 of the power consumption, 1,000,000 times faster, and have a semi-permanent advantage compared to conventional incandescent bulbs that use light generated by heating a filament. In addition, it has been remarkably developed and improved in various fields of application, and is used for precision semiconductor equipment inspection devices, electronic display panels such as automobile instrument panels, electronic signs, industrial machine indicators, and various traffic safety signals.

도 1은 종래의 일반적인 LED 전구 구조를 보여주는 것으로서, 도시된 바와 같이, 종래의 LED 전구(10)는 LED(1) 및 인쇄회로기판(2)으로 이루어진 LED모듈(3)과, 상기 LED모듈(3)을 보호함과 동시에 상기 LED(1)에서 발생한 빛을 확산시키는 돔(dome) 형태의 커버(4)와, 상기 LED모듈(3)에서 발생하는 열을 방열시키기 위한 방열부(5)로 구성된 LED발광모듈(6)과; 상기 외부의 전원장치로부터 전원을 제공받아 LED모듈(3)로 공급하는 전원공급모듈(PSU;Power supply unit;7)과; 전원공급모듈(7)을 외부의 전원장치와 연결된 설치 대상물에 연결하여 접속시키는 연결모듈(8)로 구성된다. 그리고, 상기 LED발광모듈(6)과 전원공급모듈(7) 및 연결모듈(8)은 서로 일체로 결합된 구조를 갖는다, 이러한 LED 전구(10)는 외면에 나사산 형태의 소켓부가 형성된 연결모듈(8)을 LED 전구의 설치 대상물에 나사체결 방식으로 결합하여 외부의 전원장치와 전기적인 접속이 이루어지도록 되어 있다.1 shows a conventional general LED bulb structure, as shown, the conventional LED bulb 10 is an LED module (3) consisting of an LED (1) and a printed circuit board (2), and the LED module ( 3) a dome-shaped cover 4 for protecting the light and diffusing light generated from the LED 1 and a heat dissipation part 5 for dissipating heat generated from the LED module 3. LED light emitting module 6 and configured; A power supply module (PSU; 7) which receives power from the external power supply and supplies the power to the LED module 3; It consists of a connection module (8) for connecting and connecting the power supply module (7) to the installation object connected to the external power supply. In addition, the LED light emitting module 6, the power supply module 7 and the connection module 8 has a structure that is integrally coupled to each other, the LED bulb 10 is a connection module formed with a threaded socket portion on the outer surface ( 8) is screwed into the installation object of the LED bulb to make electrical connection with the external power supply.

그러나 상기와 같은 종래의 LED 전구(10)는 전구를 구성하는 LED발광모듈(6)과 전원공급모듈(7) 및 연결모듈(8)이 서로 일체로 연결된 일체형 구조로 되어 있었기 때문에 각 모듈별로 상대적인 수명차가 있어도 교체가 불가능한 불합리한 단점이 있었다. 즉, 일반적인 LED발광모듈(6)의 내구 수명이 10만 ~ 20만 시간인 반면, 전원공급모듈(7)은 2만 ~ 3만 시간 정도의 짧은 내구수명을 가지는데, 전원공급모듈(7)의 수명이 다하여도 교체가 불가능하였고, 이로써 기타 다른 모듈의 수명이 많이 남아 있음에도 불구하고 결국 LED 전구 전체를 폐기처리해야만 하는 경제적 손실과, 환경적 폐해를 야기하는 문제가 있었다.However, the conventional LED bulb 10 as described above has a relative structure for each module because the LED light emitting module 6 and the power supply module 7 and the connection module 8 constituting the bulb has an integral structure connected integrally with each other. There was an unreasonable disadvantage of not being able to replace it even with a lifespan difference That is, while the endurance life of the general LED light emitting module 6 is 100,000 to 200,000 hours, the power supply module 7 has a short endurance life of about 20,000 to 30,000 hours, the power supply module (7) It was impossible to replace the battery at the end of its lifespan.

이하, 본 발명의 바람직한 실시 예를 첨부 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 분리형 LED 전구의 구성을 도시한 구성도이고, 도 3은 도 2의 분해도이며, 도 4는 LED발광모듈과 전원공급모듈 사이의 간격조절 구조를 보여주는 예시도이다.2 is a block diagram showing the configuration of a separate LED bulb according to the present invention, Figure 3 is an exploded view of Figure 2, Figure 4 is an exemplary view showing a gap control structure between the LED light emitting module and the power supply module.

도 2 내지 도 4를 참조하면, 본 발명에 따른 LED 전구(100)는, LED발광모듈(110)과, 상기 LED발광모듈(110)과 연결되며, 외부에서 전원을 제공받아 상기 LED모듈(103)로 공급하는 전원공급모듈(120)과, 상기 전원공급모듈(120)을 외부의 전원장치(미도시)와 연결하는 연결모듈(130)을 포함하여 구성된다.2 to 4, the LED bulb 100 according to the present invention is connected to the LED light emitting module 110 and the LED light emitting module 110, and receives power from the external LED module 103. It is configured to include a power supply module 120 for supplying the power supply module 120, and a connection module 130 for connecting the power supply module 120 with an external power supply (not shown).

상기 LED발광모듈(110)은 빛을 발산하는 LED(101)와 상기 LED(101)가 장착되는 인쇄회로기판(PCB;102)으로 이루어진 LED모듈(103)과, 상기 LED모듈(103)을 보호함과 동시에 상기 LED(101)에서 발생한 빛을 확산시키는 돔(dome) 형태의 커버(104)와, 상기 LED(101) 및 상기 전원공급모듈(120)에서 발생하는 열을 외부로 방출시키기 위한 방열부(105)로 구성된다The LED light emitting module 110 includes an LED module 103 consisting of an LED 101 emitting light and a printed circuit board (PCB) 102 on which the LED 101 is mounted, and protecting the LED module 103. At the same time, a dome-shaped cover 104 for diffusing light generated from the LED 101 and heat radiation for dissipating heat generated from the LED 101 and the power supply module 120 to the outside. It is composed of a section 105

상기 연결모듈(130)은 외면에 나사산 구조를 갖는 소켓부(132)가 형성되어, 상기 소켓부(132)가 LED 전구(100)의 설치 대상물에 나사체결 방식(소켓 방식)으로 결합 됨으로써 외부의 전원장치와 전기적인 접속이 이루어지도록 되어 있다.The connection module 130 has a socket portion 132 having a thread structure on the outer surface, the socket portion 132 is coupled to the installation object of the LED bulb 100 in a screw fastening method (socket method) to the outside An electrical connection is made to the power supply.

이때, 상기 LED발광모듈(110)과 전원공급모듈(120) 상호 간에는 연결핀(106)과 연결홈(122)을 통해 서로 분리가능하게 연결된다.At this time, the LED light emitting module 110 and the power supply module 120 are connected to each other through a connecting pin 106 and a connecting groove 122 to be separated from each other.

즉, 상기 LED발광모듈(110)의 방열부(105)에는 한 쌍의 연결핀(106)이 형성되고, 상기 LED발광모듈(110)과 상호 연결되는 전원공급모듈(120)에는 연결핀(106)이 삽입되어 접속되는 한 쌍의 연결홈(122)이 형성된다. That is, a pair of connecting pins 106 are formed on the heat dissipation unit 105 of the LED light emitting module 110, and a connecting pin 106 is provided on the power supply module 120 interconnected with the LED light emitting module 110. ) Is a pair of connecting grooves 122 are formed to be connected.

따라서, 상기 LED발광모듈(110)은 상기 전원공급모듈(120)의 연결홈(122)에 연결핀(106)을 삽입 또는 분리하게 되는 간단한 과정을 통해 상기 전원공급모듈(120)과 전기적으로 접속 및 분리 가능하도록 연결될 수 있다.Therefore, the LED light emitting module 110 is electrically connected to the power supply module 120 through a simple process of inserting or removing the connection pin 106 into the connection groove 122 of the power supply module 120. And detachably connected.

이때, 상기 LED발광모듈(110)과 전원공급모듈(120) 사이는 일정한 스페이스(space)가 형성되도록 소정의 이격 간격(D1)을 두고서 연결하는 것이 바람직하다. 이렇게 되면, LED발광모듈(110)의 방열부(105)와 전원공급모듈(120)이 직접적으로 접촉되지 않기 때문에 상기 방열부(105)와 전원공급모듈(120) 사이의 열전달을 차단하여 방열효과를 현저하게 높일 수 있다. At this time, it is preferable to connect the LED light emitting module 110 and the power supply module 120 at a predetermined interval D1 so that a predetermined space is formed. In this case, since the heat dissipation unit 105 and the power supply module 120 of the LED light emitting module 110 are not in direct contact with each other, the heat dissipation effect is blocked by blocking heat transfer between the heat dissipation unit 105 and the power supply module 120. Can be significantly increased.

또한, LED발광모듈(110)과 전원공급모듈(120) 사이의 이격 간격(D1)이 LED발광모듈(110)의 방열부(105)의 대류효과를 향상시키므로 LED발광모듈(110)의 방열효과를 향상시킨다.In addition, the spaced apart interval (D1) between the LED light emitting module 110 and the power supply module 120 improves the convection effect of the heat radiating portion 105 of the LED light emitting module 110, so the heat radiation effect of the LED light emitting module 110 To improve.

아울러, 상기 전원공급모듈(120)과 연결모듈(130) 상호 간에도 LED발광모듈(110)과 전원공급모듈(120)의 연결구조와 같이 연결핀(124)과 연결홈(131)을 통해 서로 분리가능하게 연결된다.In addition, the power supply module 120 and the connection module 130 also separated from each other through the connection pin 124 and the connection groove 131, like the connection structure of the LED light emitting module 110 and the power supply module 120. Possibly connected.

이때, 상기 전원공급모듈(120)과 연결모듈(130) 사이도 일정한 스페이스(space)가 형성되도록 소정의 이격 간격(D2)을 두고서 연결함으로써, 상기 전원공급모듈(120)과 연결모듈(130) 사이의 열전달을 차단하여 방열효과를 높일 수 있다.At this time, the power supply module 120 and the connection module 130 by connecting a predetermined space (D2) with a predetermined distance (D2) so that a predetermined space (space) is also formed, the power supply module 120 and the connection module 130. By blocking the heat transfer between the heat dissipation effect can be enhanced.

그리고, 상기 각각의 모듈(110)(120)(130)을 연결하는 연결핀(106)(124)에 일정간격으로 이격된 복수의 홈(107)을 형성하고, 상기 연결핀(106)(1024)이 끼워지는 연결홈(122)(131)의 내측에 상기 홈(107)에 선택적으로 끼워지는 복수의 돌기(121)가 형성된다.In addition, a plurality of grooves 107 spaced at predetermined intervals are formed in the connection pins 106 and 124 connecting the respective modules 110, 120, and 130, and the connection pins 106 and 1024. A plurality of protrusions 121 are selectively inserted into the grooves 107 inside the connection grooves 122 and 131 into which the grooves are fitted.

이렇게 형성하게 되면, 연결핀(106)(124)과 연결홈(122)(131)에 의해 각각의 모듈(110)(120)(130)이 연결되는 경우 상기 복수의 홈(107)과 돌기(121)를 이용하여 각 모듈(110)(120)(130) 사이의 연결 간격을 자유롭게 조절할 수 있게 된다. 이에 따라, LED 전구(100)의 전체 길이가 조절 가능해지기 때문에 설치장소의 환경에 따라 LED 전구(100)의 길이를 적절히 가변시켜 설치할 수 있는 장점이 있다.When formed in this way, when each module 110, 120, 130 is connected by a connecting pin 106, 124 and the connecting grooves 122, 131, the plurality of grooves 107 and the protrusion ( By using 121, it is possible to freely adjust the connection gap between each module (110, 120, 130). Accordingly, since the entire length of the LED bulb 100 is adjustable, there is an advantage that the length of the LED bulb 100 can be appropriately changed according to the environment of the installation place.

또한, 본 발명은 LED 전구(100)가 설치될 입력 전원의 형태에 따라 AC(교류) 또는 DC(직류)형 전원공급모듈(120)로 교체적용하여 사용할 수 있다.In addition, the present invention can be used to replace the AC (AC) or DC (DC) type power supply module 120 according to the type of the input power to be installed LED bulb 100.

한편, 도 5는 본 발명에 따른 연결모듈의 다른 형태를 보여주는 것으로서, LED 전구 설치 대상물에 플러그 방식으로 접속되는 연결모듈을 보여주고 있다.On the other hand, Figure 5 shows another form of the connection module according to the invention, it shows a connection module that is connected to the LED bulb installation object in a plug manner.

도 5에 도시한 바와 같이, 연결모듈(140)의 일측에는 전원공급모듈(120)의 연결핀(124)이 접속되는 한 쌍의 연결홈(141)이 형성되고, 타측에는 LED 전구(100) 설치 대상물에 접속되는 한 쌍의 플러그(142)가 형성된 구조를 갖는다. As shown in FIG. 5, one side of the connection module 140 is provided with a pair of connection grooves 141 to which the connection pins 124 of the power supply module 120 are connected, and the LED bulb 100 on the other side. It has a structure in which a pair of plugs 142 connected to the installation object are formed.

이와 같이, 본 발명에 따른 LED 전구(100)는 전원공급모듈(120)에 전술된 소켓형 연결모듈(130)이나 플러그형 연결모듈(140)을 자유롭게 교체 장착하여 사용하도록 되어 있기 때문에 설치 대상물의 접속부 형태에 맞는 연결모듈만을 교체함으로써 LED 전구(100)의 설치에 따른 호환성을 높일 수 있다.As such, the LED bulb 100 according to the present invention is free to replace and use the socket-type connection module 130 or the plug-type connection module 140 described above in the power supply module 120 of the installation target It is possible to increase the compatibility according to the installation of the LED bulb 100 by replacing only the connection module for the type of connection.

그리고, 도 6은 전술된 전원공급모듈(120)과 소켓형 연결모듈(130) 사이에 또 다른 형태의 연결모듈을 끼워 넣어 연결시킨 LED 전구의 모습을 보여주는 것이다.And, Figure 6 shows the appearance of the LED bulb connected by inserting another type of connection module between the power supply module 120 and the socket-type connection module 130 described above.

즉, 전원공급모듈(120)과 소켓형 연결모듈(130) 사이에 전술된 도 5의 형태와 유사한 플러그형 연결모듈(140)을 끼워 넣어 일렬로 결합시킨다. 이때, 상기 플러그형 연결모듈(140)의 일측에는 방열부(105)의 연결핀(106)이 끼워져 접속되고, 다른 일측에는 소켓형 연결모듈(130)의 연결홈(131)에 끼워져 접속되는 연결핀(144)을 형성하여 접속시키게 된다.That is, between the power supply module 120 and the socket-type connection module 130 by inserting the plug-type connection module 140 similar to the form of FIG. 5 described above are coupled in a line. At this time, one side of the plug-type connection module 140 is connected to the connection pin 106 of the heat dissipation unit 105 is connected, the other side is connected to the connection groove 131 of the socket-type connection module 130 is connected The pin 144 is formed and connected.

이와 같이, 서로 다른 형태를 갖는 연결모듈(130)(140)을 복수 개 구비하여 일렬로 결합하여 구성함으로써, 설치환경에 따라 연결모듈(130)(140)의 연결 개수를 달리하여 LED 전구(100)의 전체 길이를 자유롭게 조절해가면서 용이하게 설치할 수 있다.As such, by providing a plurality of connection modules (130, 140) having a different form and coupled in a row, LED bulb 100 by varying the number of connections of the connection module (130, 140) according to the installation environment It can be easily installed while adjusting the overall length of the product freely.

한편, 도 7은 본 발명의 다른 실시 예로서, 절곡형 연결모듈이 적용된 LED 전구의 모습을 보여주는 것이다. 도시된 바와 같이, LED 전구의 전원공급모듈(120)에 연결되는 연결모듈을 "L"자 형태의 플러그형 연결모듈(140)로 적용할 수 있다. On the other hand, Figure 7 is another embodiment of the present invention, shows a state of the LED bulb to which the bent connection module is applied. As shown, the connection module connected to the power supply module 120 of the LED bulb can be applied to the plug type connection module 140 of the "L" shape.

즉, 'L'자 형태로 절곡된 연결모듈(140)의 일측은 전원공급모듈(120)에 연결하여 접속하고 타측은 플러그(142)를 설치 대상물에 꼽아 외부의 전원장치와 접속시키게 된다. 이때, 상기 연결모듈(140)은 위의 "L"자형 이외에 다양한 형상으로 변경하여 적용할 수 있다.That is, one side of the connection module 140 bent in the 'L' shape is connected to the power supply module 120 and connected to the other side plug the plug 142 to the installation object to be connected to the external power supply. At this time, the connection module 140 may be applied to various shapes in addition to the above "L" shape.

이와 같이 본 발명의 LED 전구에 절곡형 연결모듈(140)을 연결하여 설치하게 되면, 설치환경에 크게 구애받지 않고서도 LED 전구(100)를 용이하게 설치할 수 있는 장점이 있다.As such, when the bend-type connection module 140 is connected to and installed in the LED bulb of the present invention, there is an advantage that the LED bulb 100 can be easily installed without being largely affected by the installation environment.

한편, 도 8은 본 발명의 또 다른 실시 예로서, AC 전원을 입력 전원으로 사용하는 LED 전구의 구성을 보여주고 있다. Meanwhile, FIG. 8 illustrates a configuration of an LED bulb using AC power as an input power as another embodiment of the present invention.

도 8에서 보는 바와 같이, 교류전원인 AC 전원이 입력 전원인 경우 전술된 실시 예의 전원공급모듈(120)을 사용하지 않고서 LED발광모듈(110)의 방열부(105)에 연결모듈(130)을 직접 연결하여 사용할 수 있다. As shown in FIG. 8, when AC power, which is AC power, is input power, the connection module 130 is directly connected to the heat radiating unit 105 of the LED light emitting module 110 without using the power supply module 120 of the above-described embodiment.

In addition, the connection module 130 is detachably connected in a state of maintaining a predetermined distance from the heat dissipation unit 105 as described above.

이와 같이, 본 발명은 LED 전구(100)가 설치될 입력 전원이 AC 전원일 경우, LED모듈(103)을 교류형(AC) LED모듈 패키지로 적용하게 되면 별도의 전원공급모듈을 설치하지 않고서도 방열성능이 우수한 LED 전구를 제공할 수 있다.As such, when the input power to be installed LED bulb 100 is AC power, the LED module 103 is applied to the AC-type (AC) LED module package without installing a separate power supply module LED bulbs with excellent heat dissipation can be provided.

상술한 구성을 갖는 본 발명의 LED 전구(100)는 전구를 구성하는 LED발광모듈(110), 전원공급모듈(120), 연결모듈(130)(140)이 서로 분리가능한 분리형으로 구성됨으로써, 필요 시 각 모듈별로 자유롭게 교체 사용할 수 있는 장점이 있다. 특히, 다른 모듈보다 내구 수명이 상대적으로 짧은 전원공급모듈(120)을 지속적으로 교체하면서 사용할 수 있기 때문에, 종래의 일체형 LED 전구와 같이 전원공급모듈의 수명이 다하면 LED 전구 전체를 폐기할 수밖에 없었던 불합리한 폐단을 극복할 수 있고, 전원공급모듈과 기타 모듈 간의 수명차로 인한 경제적인 낭비와 환경적 폐해를 최소화시킬 수 있다.The LED bulb 100 of the present invention having the above-described configuration is necessary by being configured as a separate type that can be separated from the LED light emitting module 110, the power supply module 120, the connection module 130, 140 constituting the bulb, There is an advantage that can be used freely for each module. In particular, since the power supply module 120, which has a relatively short lifespan than other modules, can be used continuously while being replaced, it is unreasonable to dispose of the entire LED bulb at the end of the life of the power supply module, such as a conventional integrated LED bulb. Overcoming closure can be avoided, and economic waste and environmental damage caused by the lifespan difference between power supply module and other modules can be minimized.

또한, 본 발명은 LED발광모듈(110)과 전원공급모듈(120), 전원공급모듈(120)과 연결모듈(130)(140) 사이에 일정한 이격 공간을 형성함으로써, 한쪽 모듈에서 발생하는 열이 다른 한쪽 모듈로 직접 전도되는 것을 차단할 수 있기 때문에 기존의 일체형 LED 전구에 비하여 방열효과가 매우 우수한 장점이 있다.In addition, the present invention forms a constant space between the LED light emitting module 110 and the power supply module 120, the power supply module 120 and the connection module 130, 140, the heat generated in one module Because it can block the conduction directly to the other module, the heat dissipation effect is very excellent compared to the existing integrated LED bulb.
