본 발명은 LED 파일럿 램프에 관한 것이다. The present invention relates to an LED pilot lamp.

종래의 소켓 전구는 진공된 유리구 속의 필라멘트에 전기를 통하여 발광되도 록 하여 빛을 얻는 조명기구이다. 이러한 필라멘트 전구를 개선하여 절전 효과 및내구성을 향상시킬 수 있게 한 것이 LED 소켓전구 또는 LED 램프이다. Conventional socket bulbs are luminaires that emit light through electricity to the filaments in the vacuumed glass sphere. It is an LED socket bulb or LED lamp that has improved such a filament bulb to improve the power saving effect and durability.

종래 LED를 사용하는 파일럿 램프는 한국 실용신안공고 20-0210801호 등에 개시되어 있다. 종래의 파일럿 램프는 도 1 및 도 2에 도시된 바와 같이 LED 발광 소자가 실장된 PCB 기판(20)이 중간 결합부(30) 상에 올려 놓아지고 중간 결합부의 하측으로 소켓부(10)를 결합시켜 형성한다. 중간 결합부(30)의 외주면에는 소켓부와의 결합을 위한 수직 돌기(60)를 형성하여 소켓부의 상부 내측으로 중간 결합부를 강제 끼움시키면 수직돌기가 있는 부분이 다소 그 직경이 수축되면서 긴밀하게 끼워지게 되며 상호 결합된 후에는 상기 수축된 부분의 탄발력에 의하여 수직돌기(60)가 소켓부(10)의 내주면에 강력하게 밀착되게 된다. PCB 기판 하측으로 접속되어 연장되는 두 개의 리드선의 끝단은 소켓의 측면과 하부의 단자에 각각 납땜 결합된다. 그 후 에폭시 수지(40)를 충전하여 PCB 기판 전체가 에폭시 수지에 매립되게 하여 파일럿 램프를 완성한다. A pilot lamp using a conventional LED is disclosed in Korean Utility Model Publication No. 20-0210801. In the conventional pilot lamp, as shown in FIGS. 1 and 2, the PCB substrate 20 on which the LED light emitting device is mounted is placed on the intermediate coupling portion 30, and the socket portion 10 is coupled to the lower side of the intermediate coupling portion. To form. On the outer circumferential surface of the intermediate coupling portion 30 forms a vertical protrusion 60 for coupling with the socket portion, forcibly inserting the intermediate coupling portion into the upper portion of the socket portion, and the vertical protrusion portion is closely contracted while its diameter shrinks somewhat. After being coupled to each other, the vertical protrusion 60 is strongly adhered to the inner circumferential surface of the socket part 10 by the elasticity of the contracted portion. The ends of the two lead wires which are connected and extended under the PCB board are soldered to the terminals of the side and the bottom of the socket, respectively. After that, the epoxy resin 40 is filled so that the entire PCB substrate is embedded in the epoxy resin to complete the pilot lamp.

종래의 필라멘트 전구와 비교할 때 이러한 파일럿 램프는 LED 발광소자로부터 발광되는 빛이 한 방향으로 발산된다는 단점이 있다. Compared with the conventional filament bulb, such a pilot lamp has a disadvantage in that light emitted from the LED light emitting device is emitted in one direction.

본 발명은 종래의 LED 파일럿 램프의 방향성의 문제를 특수하게 디자인된 글 로브 캡에 의하여 극복하여 빛을 넓은 각도로 분산하여 발산시켜 주는 것을 그 목적으로 한다.
The object of the present invention is to overcome the problem of the directionality of the conventional LED pilot lamp by a specially designed glove cap to distribute the light at a wide angle to diverge.

한편 본 발명은 별도의 추가적인 구조 없이 글로브 캡의 형상만 변경하여 제조단가의 증가 없이 LED 파일럿 램프가 갖는 방향성의 문제를 극복하여 필라멘트 전구처럼 다방향 발광성을 갖게 하는 것을 그 목적으로 한다.

The present invention surrounds a PCB substrate 300 on which a socket portion 308, an LED light emitting element 302 electrically connected to the socket portion is mounted, and at least a portion of a hemisphere in the direction of light emitted from the LED light emitting element.

이하 첨부도면을 참조하여 본 발명을 상세히 설명한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명의 일 실시예의 사시개략도이고 도 4는 이의 분해 결합도이다. 이에 도시된 바와 같이 PCB기판(300)에 LED 발광소자(302)가 실장되어 있어서 LED 발광소자에서 빛을 발광하게 된다. 바람직하게는 LED 발광소자가 실장된 PCB 기판(300)은 합성수지재로 형성된 중간 결합부(304) 상에 올려 놓여진다. 중간 결합부의 상측으로는 글로브 캡(306)이 결합되고 하측으로는 소켓부(308)이 결합된다. 중간결합부(304)와 소켓부의 결합 등은 종래 기술과 동일하므로 자세한 설명은 생략한다. 3 is a perspective schematic view of one embodiment of the present invention and FIG. 4 is an exploded bond thereof. As shown therein, the LED light emitting device 302 is mounted on the PCB 300 to emit light from the LED light emitting device. Preferably, the PCB substrate 300 on which the LED light emitting device is mounted is placed on the intermediate coupling part 304 formed of a synthetic resin material. The glove cap 306 is coupled to the upper side of the intermediate coupling portion, and the socket portion 308 is coupled to the lower side. Since the coupling between the intermediate coupling portion 304 and the socket portion is the same as in the prior art, a detailed description thereof will be omitted.

PCB 기판 상의 LED 발광소자에서 발광되는 빛은 발광소자의 직상부측으로 진 행하는데 PCB 기판의 일측 방향으로는 도시된 바와 같이 글로브 캡(306)이 둘러싸고 있다. 도 4의 분해 결합도에는 글로브 캡의 부분단면이 도시되어 있다. 글로브 캡은 투명 소재의 합성수지재 또는 유리 등의 소재로 형성되는데 도시된 바와 같이 특수한 형상을 갖고 있다. 글로브 캡의 도면에서의 상측을 향하는 외측면의 적어도 일부에는 오목하게 함몰된 오목부(312)가 형성되어 있고 그 반대편 이에 대향하는 내측면에도 오목부(310)가 형성되어 있다. 즉, 글로브 캡의 외부를 향하는 외측면의 적어도 일부에는 오목하게 함몰된 오목부(312)가 형성되어 있고, 저면의 LED측을 향하는 내측면에도 도시된 바와 같이 오목하게 함몰된 오목부(310)가 형성되어 있다. 구분을 위하여 내측면에 형성된 오목부를 제 1 오목부(310)라고 하고 외부를 향하는 외측면에 형성된 오목부를 제 2 오목부(312)라고 한다. The light emitted from the LED light emitting device on the PCB board proceeds directly to the upper side of the light emitting device, and the globe cap 306 is surrounded as shown in one direction of the PCB board. 4 is a partial cross section of the glove cap. The glove cap is formed of a transparent resin material or a material such as glass and has a special shape as shown. In at least part of the outer surface facing upward in the figure of the glove cap, a recessed recess 312 is formed, and a recess 310 is also formed on the inner side opposite to the opposite side. That is, at least a part of the outer surface facing outward of the glove cap is formed with a recessed recess 312, and the recess 310 recessed recessed as shown in the inner surface facing the LED side of the bottom is shown. Is formed. The concave portion formed on the inner side for the purpose of division is called the first concave portion 310 and the concave portion formed on the outer side facing outward is called the second concave portion 312.

다시 말하면 글로브 캡의 내측면 즉 LED를 향하는 면의 적어도 일부에 제 1 오목부가 형성되고, 제 1 오목부의 반대편에 즉 글로브 캡의 외측면 적어도 일부에 제 2 오목부가 형성된다. 또한 필요에 따라 제 1 오목부가 LED에 충분히 가깝게 위치하도록 글로브 캡의 일부가 두껍게 형성되어 하측으로 연장되어 LED 광의 통로가 되는 광통로부(314)가 형성될 수도 있다. 또한 바람직하게는 제 2 오목부의 일부(316)는 표면이 거칠게 처리되어 빛의 방향을 더 극적으로 변화시켜 산란되게 한다. In other words, a first recess is formed on at least a portion of the inner side of the glove cap, that is, a surface facing the LED, and a second recess is formed on the opposite side of the first recess, that is, at least a portion of the outer surface of the glove cap. In addition, if necessary, a light path portion 314 may be formed so that a part of the globe cap is thickened so that the first recess is sufficiently close to the LED and extends downward to become a path of the LED light. Also preferably, a portion 316 of the second recess is roughened at the surface to more scatter the scattering of the light direction.

도 5에는 본 발명의 일실시예의 부분단면도가 도시되어 있으며 빛의 진행방 향의 예시도가 도시되어 있다. 이에 도시된 바와 같이 LED발광소자에서 발산된 빛은 상측으로 일정 방향으로 진행하나 1차적으로 제 1 오목부(310)에서 굴절되어 넓은 보다 각도로 퍼져 나가게 되며 2차적으로 제 2 오목부(312)에서 2차적으로 추가 굴절되면서 동시에 제 2 오목부에 형성된 미세하게 울퉁불퉁한 표면에 의하여 산란되어 다양한 방향으로 진행하면서 외부로 발산된다. 5 is a partial cross-sectional view of an embodiment of the present invention and an exemplary view of the direction of travel of light. As shown in the drawing, the light emitted from the LED light emitting device proceeds upward in a predetermined direction, but is first refracted by the first concave portion 310 to spread out at a wider angle, and secondly, the second concave portion 312. In the second refraction at the same time is scattered by the finely bumpy surface formed in the second concave portion is emitted to the outside while proceeding in various directions.

본 발명은 종래의 LED 파일럿 램프의 방향성의 문제를 특수하게 디자인된 글로브 캡만에 의하여 극복하여 빛을 넓은 각도로 분산하여 발산시켜 주는 효과를 갖는다.
