종래에는 외장캡(12)이 짧게 형성되어 외장캡(12)의 외부로 전원모듈이 돌출된 형태로 구성되어 있었으나, 본원 발명은 외장캡(12)의 내부에 전원모듈이 완전히 수용되어 전원모듈이 외부로 노출되거나 시인되지 않도록 외장캡(12)의 길이를 길게 형성하는 것을 특징으로 한다.Conventionally, the outer cap 12 is formed in a short form so that the power module protrudes to the outside of the outer cap 12, the present invention, the power module is completely accommodated inside the outer cap 12, the power module is It characterized in that to form a long length of the outer cap 12 so as not to be exposed or visible to the outside.
외장캡(12)은 종래의 형광등과 같이 금속재질로 형성될 수도 있지만, 불투명한 합성수지 재질로 제작되어도 무방하다.The outer cap 12 may be formed of a metallic material as in a conventional fluorescent lamp, but may be made of an opaque synthetic resin material.

도 2는 본 발명의 제 1 실시예에 따른 막대형 LED 조명기구의 분리사시도이다.2 is an exploded perspective view of a bar-shaped LED lighting device according to a first embodiment of the present invention.
도시된 바와 같이, 본 발명의 제 1 실시예에 따른 막대형 LED 조명기구는 외장캡(12)의 내부에 에폭시로 밀봉되는 전원모듈(20)과, 복수개의 LED(L)가 기판의 표면에 배열되어 구성되는 발광모듈(22a, 22b)과, 발광모듈(22a,22b)의 길이에 대응하며 발광모듈(22a, 22b)에 밀착되어 열을 흡수 및 발산 시키는 히트싱크모듈(24)과, 발광모듈(22a, 22b)을 수용하도록 히트싱크모듈(24)에 슬라이딩 결합되고, 히트싱크모듈(24)과 결합된 상태에서 외장캡(12)과 결합되는 투광관(14)을 포함한다.As shown, the rod-shaped LED lighting device according to the first embodiment of the present invention is a power module 20 which is sealed with epoxy in the interior of the outer cap 12, a plurality of LED (L) on the surface of the substrate A heat sink module 24 corresponding to the lengths of the light emitting modules 22a and 22b and the light emitting modules 22a and 22b and arranged in close contact with the light emitting modules 22a and 22b to absorb and dissipate heat; Sliding coupled to the heat sink module 24 to accommodate the modules (22a, 22b), and includes a light-emitting tube 14 coupled to the outer cap 12 in a state coupled to the heat sink module 24.
전원모듈(20)은 전극단자(12a)에서 공급되는 전원을 발광모듈(22a, 22b)에 구비된 LED(L)을 구동하기 적합한 전원으로 변환해주는 역할을 수행한다.The power module 20 converts the power supplied from the electrode terminal 12a into a power suitable for driving the LED L provided in the light emitting modules 22a and 22b.
이때 전원을 변환하는 방식은 2가지가 있다.At this time, there are two ways to convert the power.
첫번째로는 종래의 안정기가 부착된 형광등 케이스에서 그대로 사용할 수 있도록 안정기를 거친 전원을 LED 구동에 적합한 전원으로 변환하는 방식이고, 두번째로는 안정기를 거치지 않은 교류전원을 직접공급받아 LED 구동에 적합한 전원으로 변환하는 방식이다.The first method is to convert the power passed through the ballast into a power suitable for driving the LED so that it can be used as it is in the fluorescent lamp case with the conventional ballast. The second is a power supply suitable for driving the LED by directly receiving AC power without the ballast. This is how you convert it.
전원모듈(20)은 전체 막대형 LED 조명기구의 좌우의 외관상의 대칭과 무게의 배분을 위하여 양측 외장캡(12)에 각각 설치되는 것이 바람직하다.The power supply module 20 is preferably installed on both exterior caps 12 for the distribution of the symmetrical appearance and weight of the left and right of the entire bar-shaped LED lighting fixtures, respectively.
물론, 경우에 따라서는 일측의 외장캡(12)에만 전원모듈(20)이 형성될수도 있다.Of course, in some cases, the power module 20 may be formed only on the outer cap 12 of one side.
전원모듈(20)은 외장캡(12)에 에폭시로 밀봉되는 것이 바람직하다. 이는 외부의 수분이나 이물질이 전원모듈(20)측으로 침투하는 것을 방지하여 전원모듈(20)의 고장을 방지하기 위함이다.The power module 20 is preferably sealed with an epoxy to the outer cap 12. This is to prevent failure of the power module 20 by preventing external moisture or foreign matter from penetrating into the power module 20 side.
전원모듈(20)이 양측으로 분리되어 설치되는 각각의 전원모듈(20)이 개별적으로 전원변환의 기능을 수행하는 형태가 될수도 있고, 전기적인 장치로서는 하나의 전원변환기능을 수행하는 데 양측으로 분리되어 형성될 수도 있다.Each power module 20, in which the power module 20 is separated and installed on both sides, may be in the form of individually performing power conversion, and as an electrical device, is separated on both sides to perform one power conversion function. It may be formed.
즉, 일측의 전원모듈(20)이 일측의 발광모듈(22a)에만 전원을 공급하는 방식으로 형성되거나, 양측의 전원모듈(20)이 전체의 발광모듈(22a, 22b)에 전원을 공급하는 방식으로 형성될 수 있다는 것이다.That is, the power module 20 on one side is formed in such a manner as to supply power only to the light emitting module 22a on one side, or the power module 20 on both sides to supply power to the entire light emitting modules 22a and 22b. It can be formed as.
도시된 바와 같이, 본 발명에 따른 LED 조명기구는 발광모듈(22a, 22b)이 복수의 기판으로 형성되어 발광모듈(22a, 22b) 상호간에 탈부착 가능하도록 형성되는 것을 특징으로 한다. 제1실시예의 경우 발광모듈(22a,22b)이 2개 형성된 타입을 나타낸 것이다. 3개 혹은 그 이상이 결합되는 형태로 형성될 수도 있다.As shown, the LED lighting device according to the present invention is characterized in that the light emitting modules 22a and 22b are formed of a plurality of substrates so that the light emitting modules 22a and 22b are detachable from each other. In the first embodiment, two light emitting modules 22a and 22b are formed. Three or more may be formed in a combined form.
정상적인 LED의 수명은 10년에 달하는 것으로 알려졌으나, 불량품인 경우에는 수명이 극히 짧을 수도 있다.The lifetime of a normal LED is known to reach 10 years, but in the case of a defective product, the lifetime may be extremely short.
그런데, 전체 발광모듈이 하나의 기판으로 형성되어 있는 경우에는 한두개의 LED에서 불량이 발생하더라도 전체 기판을 교체해야 하므로 수리에 과도한 비용이 소모되며 자원이 낭비될 수 있다.However, in the case where the entire light emitting module is formed of one substrate, even if a defect occurs in one or two LEDs, the entire substrate needs to be replaced, so excessive cost is required for repair and resources may be wasted.
본 발명은 발광모듈이 상호 결합하여 연결될 수 있도록 함으로써 불량 LED가 발생할 경우, 연결된 발광모듈을 분리하고 불량이 발생한 발광모듈만 교체할 수 있는 구조를 제공한다.The present invention provides a structure that allows the light emitting modules to be connected to each other to be connected to each other when a bad LED occurs, to separate the connected light emitting module and to replace only the light emitting module having a failure.
따라서, 자원의 낭비를 줄이고 수리 작업이 간편하고 신속하게 이루어질 수 있다.Therefore, the waste of resources and the repair work can be made easily and quickly.

히트싱크모듈(24)은 막대형 LED 광원장치 전체 길이에 대응하도록 1개 형성될 수 있도 있고, 발광모듈(22a, 22b)처럼 소정 길이로 형성된 것들을 길이방향으로 연결하여 조립되는 형태로 형성될 수도 있다.One heat sink module 24 may be formed to correspond to the entire length of the bar-shaped LED light source device, or may be formed in a form that is assembled by connecting those formed in a predetermined length such as light emitting modules 22a and 22b in the longitudinal direction. have.
다만, 히트싱크모듈(24)은 전기적인 접속이 필요치 않으므로 기계적으로 상호가 체결되는 것으로 조립된다.However, since the heat sink module 24 does not require electrical connection, the heat sink module 24 is assembled to be mutually mechanically fastened.
히트싱크모듈(24)은 도전성의 금속재질로 이루어지나, 전기적인 역할은 수행하지 않는 것이므로, 발광모듈(22a,22b)이나 전원모듈(20)과 통전되지 않도록 접촉부위에 절연층을 형성하거나 절연필름이 부착될 수 있다.Since the heat sink module 24 is made of a conductive metal material, but does not play an electrical role, the heat sink module 24 forms or insulates an insulating layer on the contact portion so as not to be energized with the light emitting modules 22a and 22b or the power module 20. The film can be attached.

It is preferable that the light-transmitting tube 14 itself is not discolored by external ultraviolet rays. In addition, it is preferable to give a shape capable of scattering and diffusing light on the inner surface of the light emitting tube 14 so as to uniformly diffuse the light emitted from the LED which is the point light source.
투광관(14)은 기초수지로는 투명한 합성수지를 기초수지로 제작되며, 상술한 바와 같은 빛의 확산기능을 수행하기 위한 확산제와, 자외선을 흡수 또는 차단하기 위한 자외선 흡수제 및 자외선 차단제가 첨가제로 혼합된 재질로 이루어지는 것이 바람직하다.The floodlight tube 14 is made of a transparent synthetic resin as a base resin, and a diffusion agent for performing the light diffusion function as described above, and an ultraviolet absorber and a sunscreen agent for absorbing or blocking ultraviolet rays as additives.
