As shown in Figures 1a to 6, the LED luminaire having a waterproof function according to the present invention, a thermal conductive panel (4) made of a plate having a thermal conductivity; The heat sink 62 coupled to the lower outer periphery of the heat conduction panel 4 by having a space in the center, and the PCB 72 coupled to the inner surface of the heat sink 62 and the LED 74 planted A light emitting unit 6 composed of a light emitting unit 7 having, and a light scattering panel 65 coupled to an inner space of the heat sink 62 so as to radiate light emitted from the LED 74 downward; A frame (8) in which the light emitting unit (6) is accommodated and coupled to the lower outer periphery of the heat conduction panel (4); It is configured to include; it is coupled to the upper and lower surfaces of the heat sink 62, the heat-conducting panel 4 or the waterproof member 9 in close contact with the outer surface of the frame 8 to provide water tightness.

상기 방수부재(9)는 단면이 직사각형이며 소정길이를 갖는 바(bar)타입이며, 방수부재(9)의 단부에는 끼움홈(93)이 형성된다(도 6 참조). The waterproof member 9 has a rectangular cross section and a bar type having a predetermined length, and a fitting groove 93 is formed at an end of the waterproof member 9 (see FIG. 6 ).

상기 복수의 방수부재(9) 각각의 단부를 연결하여 직각을 이루도록 하는 모서리 연결구(95)가 구비된다. Corner connectors 95 are provided to connect the ends of the plurality of waterproof members 9 to form a right angle.

상기 모서리 연결구(95)는 양측에 끼움편(952)이 90˚의 사잇각을 갖도록 형성되며 각 끼움편(952)이 각 방수부재(9)에 끼움결합된다. The corner connector 95 is formed so that the fitting pieces 952 on both sides have a 90-degree angle, and each fitting piece 952 is fitted to each waterproof member 9.

따라서 4개의 방수부재(9)가 각각의 단부끼리 모서리 연결구(95)와 각기 연결되어 사각형을 이루게 된다. Therefore, the four waterproof members 9 are respectively connected to the corner connector 95 between each end to form a square.

The heat sink 62 is an extruded product made of aluminum and has a rod shape but is formed with an inclined surface on the outside, and a coupling groove in which the PCB 72 and the light scattering panel 65 are combined is formed inside, and the upper surface And a waterproof member 9 is tightly coupled to the lower surface.

히트싱크(62)는 외측에 경사지게 경사면이 형성되어 전술한 프레임(8)의 내측 경사면을 따라 용이하게 삽입되어 결합될 수 있다. The heat sink 62 is formed with an inclined surface inclined on the outside, and can be easily inserted and coupled along the inner inclined surface of the frame 8 described above.

일 예에 따르면 도 2 및 도 3에 도시된 바와 같이, 4개의 히트싱크(62)가 연결되어 사각형상을 이루도록 한다. According to an example, as shown in FIGS. 2 and 3, four heat sinks 62 are connected to form a quadrangular shape.

이하 전술한 본 발명의 실시예에 대한 작용을 설명한다.Hereinafter, the operation of the above-described embodiment of the present invention will be described.

히트싱크(62)의 내측에 피씨비(72)를 결합하고, 피씨비(72)의 엘이디에 접하도록 하여 광분산패널(65)을 결합한다. The PCB 72 is coupled to the inside of the heat sink 62, and the light scattering panel 65 is coupled to contact the LED of the PCB 72.

이후 프레임(8)의 하부에 방수부재(9)를 결합하고, 그 상부에는 히트싱크(62)를 프레임(8)의 내부에 삽입하여 안착되도록 한 후 히트싱크(62)의 상부면에 다른 방수부재(9)를 안착시킨다. Thereafter, a waterproof member 9 is coupled to the lower portion of the frame 8, and a heat sink 62 is inserted into the frame 8 to be seated inside the upper portion of the frame 8, and then the other waterproof portion is applied to the upper surface of the heat sink 62. The member 9 is seated.

이후 열전도판넬(4)을 프레임(8) 및 상부측 방수부재(9)를 덮도록 배치한 후 프레임(8)을 관통하도록 나사(89)를 체결하여 결합시킴으로써 방수성능을 갖게 된다. Thereafter, the heat conducting panel 4 is arranged to cover the frame 8 and the upper waterproof member 9, and then, by fastening the screws 89 to penetrate the frame 8, the waterproof performance is obtained.

이후 열전도판넬(4)이 결합되고, 이렇게 조립된 등기구를 천장에 장착하게 된다. Thereafter, the heat conduction panel 4 is combined, and the assembled luminaire is mounted on the ceiling.

따라서 물 청소를 하더라도 수분 침투를 방지하여 성능이 안정적으로 유지될 수 있다. Therefore, even in the case of water cleaning, performance can be stably maintained by preventing water infiltration.
