Description

천장형 ＬＥＤ 램프 본체{The ＬＥＤ lamp for ceiling model}Ceiling type LED lamp body {The LED lamp for ceiling model}

본 발명은 천장에 설치되어 실내를 밝히는 LED 램프에 관한 것으로서, 더욱 상세하게 설명하면 발광소자를 LED 소자로 형성하고 LED 소자가 발광을 할 때 발생하는 열을 자연냉각방식으로 발열을 할 수 있도록 한 천장형 LED 램프 본체에 관한 것이다.The present invention relates to an LED lamp that is installed on the ceiling to illuminate the room, and more specifically, the light emitting device is formed as an LED device, and heat generated when the LED device emits light can be generated by a natural cooling method. It relates to a ceiling type LED lamp body.

일반적으로 실내를 밝히는 램프는 양극에서 전기적 방전을 하여 방전관 내부에 삽입된 형광물질을 통해서 발광하는 형광등과, 양극에 발광체인 필라멘트를 구비하여 전기적 방전시 필라멘트가 발광하도록 한 전구가 있었다.In general, a lamp that illuminates a room includes a fluorescent lamp that emits light through a fluorescent material inserted into the discharge tube by electric discharge at an anode, and a light bulb having a filament as a light emitter at the anode to emit light when the filament is discharged.

이때, 상기 후자와 같은 전구는 유리관 내부에 충진하는 물질에 따라 수은등이나 아크등 및 할로겐 등으로 구분되고, 상기와 같은 등기구는 전압에 따라 야외에 설치되어 도로 및 인도를 밝히는 가로등이나 인도등으로 또는 저전압의 경우에는 실내를 밝히는 실내등으로 사용되고 있는 실정이다.At this time, the latter light bulb is divided into mercury lamp, arc lamp and halogen lamp according to the material to be filled in the glass tube, such a lamp is installed in the outdoor according to the voltage as a street lamp or sidewalk light to illuminate the road and sidewalks or In the case of low voltage, it is used as a room light to illuminate the room.

그리고, 전자와 같이 형광물질은 유리관 내부에 충진한 형광등을 주로 실내를 밝히는 실내등으로 사용된다.And, as in the former, the fluorescent material is mainly used as a fluorescent lamp filled inside the glass tube to illuminate the room.

따라서, 상기와 같은 등기구는 우리 생활에 있어서 없어서는 안 될 밀접한 관계를 가지고 여러 산업분야에 폭넓게 사용되고 있는 실정이다.Therefore, such a luminaire is used in a wide range of industries with a close relationship indispensable in our lives.

그러나, 상기와 같은 등기구를 사용전압이 높기 때문에 소비전력이 높아 전력을 생산하는 시설이 대형화되어야 하고 그에 따른 에너지소비가 높아 석유사용량이 증가함으로 환경오염의 하나로 지목되고 있는 실정이고, 이러한 종래의 램프는 한정된 수명이 있고 수명이 다한 램프를 폐기할 때에는 램프에 충진된 발광물질이 환경오염 물질일 뿐만 아니라 인체에 치명적인 악영향을 미치는 물질이기 때문에 별도의 분리수거를 거쳐 폐기하여야 하는 번거로움이 발생하였다,However, due to the high voltage used in such luminaires, the power consumption is high and the facilities for generating power must be enlarged, and the energy consumption is high, resulting in an increase in oil use, which is considered as one of environmental pollution. When you dispose of a lamp that has a limited lifetime and reaches the end of its life, the light emitting material filled in the lamp is not only an environmental pollutant but also a fatal adverse effect on the human body.

이러한 문제점을 감한하여 최근에서 고효율이면서 저소비할 수 있는 LED 소자를 이용한 램프의 개발이 활발하게 이루어지고 있는 실정이고 일부 상용화를 이룬 상태이다.In light of these problems, the development of lamps using LED devices that can be consumed with high efficiency in recent years has been actively conducted and some commercialization has been achieved.

그러나, 상기 LED 소자를 이용한 램프에서의 가장 큰 문제점으로서는 고효율의 LED 소자를 이용할 때에 발생하는 열을 외부로 방출하기 위한 수단을 강구하여야 하므로 LED 소자를 고정한 기판의 이면에 대단위의 방열판을 구비하고 상기 방열판과 접하여 팬을 구비하여야 하는 등 그 구조가 커서 일반 형광램프에는 적용하지 못하고 전구와 같은 형태의 램프에 적용되고 있는 실정이다.However, the biggest problem in the lamp using the LED element is to provide a means for dissipating heat generated when using a high-efficiency LED element to the outside, and a large heat sink is provided on the back surface of the substrate on which the LED element is fixed. The fan has to be provided in contact with the heat sink, so the structure is not applied to a general fluorescent lamp, but is applied to a lamp of the same type as a light bulb.

본 발명은 상기와 같이 형광등 기구와 같이 길이방향으로 이루어진 등기구에 LED 소자를 이용한 램프를 적용하기 위한 발명으로서, 하부에 LED 소자를 가지는 기판이 구비되고 중앙에는 LED 소자에 안정적인 전원을 공급하는 회로부(SMPC)를 구비하며 상부에는 LED 소자가 발광할 때 발생하는 열을 외부로 방출하는 방열판을 가지도록 함으로 LED 소자에서 발생한 열을 자연냉각방식으로 방열을 할 수 있도록 하는 천장형 LED 램프 본체를 제공하는데 본 발명의 목적이 있는 것이다.The present invention is an invention for applying a lamp using the LED element to the luminaire made in the longitudinal direction, such as a fluorescent lamp as described above, is provided with a circuit board having an LED element at the bottom and a circuit unit for supplying a stable power to the LED element in the center ( SMPC) and the upper part to have a heat sink that emits heat generated when the LED element emits to the outside to provide a ceiling-type LED lamp body that can radiate heat generated by the LED element by a natural cooling method. It is an object of the present invention.

상기와 같은 실시 수단을 가지는 본 발명은 길이방향으로 발광체인 LED 소자를 구비하고 LED 소자가 발광할 때 발생하는 열을 방열판에 의하여 외부로 자연 발산시키도록 함으로 LED 소자가 발광할 때 빛의 직진력을 가짐으로 실내전체를 밝힐 수 없어 실내 천장에 복수의 LED 램프를 구비하여야 하는 문제점을 해결한 것이고, LED 소자가 발광할 때 발생하는 열을 자연냉각방식으로 방열시켜 램프 본체의 크기를 최소화할 수 있는 장점을 가지는 발명이다.The present invention having the above-described means is provided with an LED element which is a light emitter in the longitudinal direction, and the heat generated when the LED element emits light to the outside by the heat dissipation to the outside by the heat sink, the linear force of the light when the LED element emits light This solution solves the problem of having a plurality of LED lamps on the ceiling of the room because it cannot illuminate the entire room, and minimizes the size of the lamp body by dissipating the heat generated when the LED element emits by natural cooling. It is an invention having the advantages.

이하 본 발명의 실시를 위한 구체적 내용을 첨부된 도면과 같은 실시 예로 상세히 설명하면 다음과 같다.DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

실내 천장에 고정하도록 상부 양측으로 고정날개(101)를 형성한 본체(100)와;A main body 100 having fixed wings 101 formed on both sides of the upper part to be fixed to the indoor ceiling;

상기 본체(100)의 하부에 결합하고 복수의 LED 소자(201)를 가지는 기판(200)과;A substrate 200 coupled to a lower portion of the main body 100 and having a plurality of LED elements 201;

상기 본체(100)의 중앙에 형성된 수납공간(110)에 위치하고 LED 소자(201)에 안정적인 전원을 공급하는 회로부(300)와;A circuit unit 300 positioned in the accommodation space 110 formed at the center of the main body 100 and supplying stable power to the LED element 201;

상기 본체(100)의 상부에 위치하되, 상부에 형성된 고정날개(101)의 사이에 구비되어 LED 소자(201)에서 발생한 열을 외부로 방출하도록 하는 방열판(400)으로 구성한다.Located on the upper portion of the main body 100, provided between the fixed blade 101 formed on the upper is configured as a heat sink 400 for dissipating heat generated from the LED element 201 to the outside.

이때, 상기 본체(100)의 하부 양측에는 기판(200)을 고정하고 전원을 연결하는 고정수단(120)을 구비하되, 상기 고정수단(120)에는 회로부(300)로부터 안정적인 전원을 연결하기 위한 단자(121)를 형성하고, 기판(200)의 양단에도 상기 단자(121)와 접촉하는 단자(202)를 형성한다.At this time, the lower both sides of the main body 100 is provided with a fixing means 120 for fixing the substrate 200 and connecting the power, the terminal 120 for connecting a stable power from the circuit unit 300 to the fixing means 120 The terminal 121 is formed, and terminals 202 contacting the terminal 121 are formed at both ends of the substrate 200.

그리고, 상기 본체(100)의 중앙부위에 형성되어 회로부(300)를 수납하는 수납공간(110)은 본체(100)의 하부에 구비되는 기판(200) 및 상부에 구비되는 방열판(400)과 격리시키는 차단판(111)을 형성한다.In addition, the accommodation space 110 formed at the center of the main body 100 to accommodate the circuit unit 300 is isolated from the substrate 200 provided at the bottom of the main body 100 and the heat sink 400 provided at the top. The blocking plate 111 is formed.

이때, 상기 차단판(111)은 본체(100)의 하부와 중앙부위 전체로 형성한 것으로서, 양측면은 폐쇄하고, 회로부(300)가 놓이는 이외의 부분에는 LED 소자(201)가 발광할 때 발생한 열이 상부로 상승하여 배출되도록 일정한 간격을 가지고 배출 공(112)을 형성한다.At this time, the blocking plate 111 is formed by the lower portion and the entire center portion of the main body 100, both sides are closed, the heat generated when the LED element 201 emits light in a portion other than the circuit portion 300 is placed. The discharge hole 112 is formed at regular intervals to be discharged to the upper portion.

그리고, 상기 수납공간(110)의 다른 실시로서는 하부에 위치하는 차단판(111)은 본체(100)의 면적 전체를 차지하고 상부에 위치하는 차단판(111)은 회로부(300)의 크기보다 약간 큰 형태로 형성함으로 수납공간(110)의 양측으로 방열판(400)이 위치하도록 형성한다.As another embodiment of the storage space 110, the blocking plate 111 positioned below occupies the entire area of the main body 100, and the blocking plate 111 positioned above is slightly larger than the size of the circuit unit 300. The heat sink 400 is positioned on both sides of the storage space 110 by forming the shape.

또한, 상기 방열판(400)은 복수의 수로 형성하여 단위면적을 최대한 많은 면적을 가지도록 함으로 LED 소자(201)가 발광할 때 발생하는 열을 최대한 이른 시간에 방출하도록 하고, 이같이 LED 소자(201)에서 발생하는 열을 방출하기 위하여 상기 방열판(400)의 하단이 수납공간(110)의 상부 차단판(111)과 맞닿도록 한다.In addition, the heat sink 400 is formed of a plurality of numbers so as to have a unit area as much as possible so that the heat generated when the LED device 201 emits light as early as possible, the LED device 201 as described above The lower end of the heat dissipation plate 400 is in contact with the upper blocking plate 111 of the storage space 110 in order to discharge the heat generated from the.

이때, 방열판(400)의 양측은 실내 자연바람이 통과되도록 개방한 상태이고, 방열판(400)의 높이는 본체(100)의 상부 양측에 형성된 고정날개(101)의 높이보다 작도록 한다.At this time, both sides of the heat dissipation plate 400 is open to allow the natural wind to pass through, and the height of the heat dissipation plate 400 is smaller than the height of the fixing blades 101 formed on both upper sides of the main body 100.

그리고, 상기 LED 소자(201)에서 발생한 열은 방출시키기 위한 보다 효율적인 구성으로 본체(100)의 측면에 돌출돌기(130)를 형성함으로 본체(100)의 표면적을 극대화시켜 본체(100)의 측면이 방열판의 역할을 수행할 수 있게 한 것이다. In addition, the side surface of the main body 100 is maximized by maximizing the surface area of the main body 100 by forming the protruding protrusion 130 on the side of the main body 100 in a more efficient configuration for dissipating heat generated by the LED device 201. It will be able to act as a heat sink.

이때, 상기 본체(100)의 측면으로 돌출되는 돌출돌기(130)는 고정날개(101)가 돌출된 길이보다 작게 형성함으로 본체(100)를 천장에 도시하지 않은 고정수단으로 고정시킬 때 돌출돌기(130)에 간섭을 받지 않도록 한 것이다.At this time, the protruding protrusion 130 protruding toward the side of the main body 100 is formed by the fixing blade 101 is smaller than the protruding length so that when the main body 100 is fixed by fixing means not shown in the ceiling ( 130) to avoid interference.

이와 같이 본 발명은 LED 소자(201)가 발광할 때 발생한 열을 강제적으로 방출하는 것이 아니라 방열판(400)으로 열을 전달하고 방열판(400)이 외부에 노출되 어 있어 방열판(400)을 통과하는 자연바람에 의하여 방출되게 함으로 등기구의 크기를 최소화하면서 높은 방출효과를 가지는 것이다.As such, the present invention transmits heat to the heat sink 400 instead of forcibly dissipating heat generated when the LED element 201 emits light, and the heat sink 400 is exposed to the outside to pass through the heat sink 400.
