Description

차량용 발광 다이오드 전구{Automotive LED bulb}Automotive LED Bulbs {Automotive LED bulb}

본 고안은 차량용 발광 다이오드 전구에 관한 것으로, 보다 상세하게는 차량의 후미측에 장착되는 방향 지시등, 브레이크 및 후미등, 후진등 등에 장착되는 발광 다이오드 전구에 관한 것이다.The present invention relates to a light emitting diode bulb for a vehicle, and more particularly, to a light emitting diode bulb mounted to a direction indicator light, a brake and a tail light, a reverse light and the like mounted on the rear side of the vehicle.

일반적으로, 차량의 후미측에는 후미 차량의 운전자에게 전방 차량의 운전 상태를 사전에 인지시켜 주는 방향 지시등, 브레이크 및 후미등, 후진등 등과 같은다양한 광학장치가 구비된다.In general, the rear side of the vehicle is provided with a variety of optical devices such as a turn signal, a brake and tail light, a reverse light, etc. to let the driver of the rear vehicle in advance know the driving state of the front vehicle.

종래에는, 이러한 방향 지시등, 브레이크 및 후미등, 후진등 등의 광학장치에는 통상적인 필라멘트 전구가 적용되었다. 그러나, 필라멘트 전구는 전력 소모가 상대적으로 매우 크며, 점등을 위한 반응시간이 상대적으로 긴 단점이 있었으므로 이에 대한 개선책으로 발광 다이오드 전구를 대체하여 사용하는 추세이다.Conventionally, conventional filament bulbs have been applied to such optical devices as turn indicators, brake and tail lights, and reverse lights. However, the filament bulb has a relatively high power consumption, and the reaction time for lighting has a relatively long disadvantage, so it is a trend to replace the light emitting diode bulb as an improvement.

하지만, 이러한 차량 후미측에 설치된 광학장치에 적용되는 종래의 발광 다이오드 전구는 전체적인 휘도(brightness)가 낮고, 태양광 아래에서는 국소 면적 밝기만을 밝혀주어 주변차량에게 방향 지시나 브레이크 동작 등을 제대로 전달시키지 못하며, 또한 그 최대 조사각이 30°정도에 불과하여 조사 범위가 매우 협소한 단점이 있었다.However, the conventional LED bulb applied to the optical device installed at the rear side of the vehicle has a low overall brightness and reveals only the local area brightness under sunlight, so that it does not properly transmit direction indication or brake operation to the surrounding vehicles. In addition, the maximum irradiation angle is only about 30 ° there was a very narrow range of irradiation.

또한, 종래의 발광 다이오드 전구는 발광 다이오드 자체에서 발생되는 빛의 떨림 현상 및 높은 발열의 현상을 효과적으로 제거하지 못하는 단점이 있었다.In addition, the conventional light emitting diode bulb has a disadvantage in that it does not effectively eliminate the phenomenon of shaking and high heat generated in the light emitting diode itself.

이에, 본 출원인은 이러한 종래의 단점을 극복하는 차량용 발광다이오드 전구를 국내등록실용신안공보 제316807호(이하, "선등록고안"이라 함)에 개시하였다.Accordingly, the present applicant has disclosed a light emitting diode bulb for a vehicle that overcomes these conventional disadvantages in Korean Utility Model Publication No. 316807 (hereinafter referred to as "pre-registration proposal").

그러나, 이러한 선등록고안에 의해서도 발광다이오드 자체에서 발생되는 빛의 높은 발열 현상이 효과적으로 제거되지 못하였고, 장착의 호환성이 용이하지 못한 단점이 있었다.However, even with this pre-registration proposal, the high heat generation phenomenon of the light emitted from the light emitting diode itself could not be effectively removed, and the compatibility of mounting was not easy.

본 고안은 상기와 같은 점을 감안하여 안출한 것으로, 발광 다이오드로부터 발생하는 높은 발열현상을 효과적으로 제거하며, 다양한 종류의 차량용 램프의 소켓 상에 호환이 용이하게 장착되는 차량용 발광 다이오드 전구를 제공하는 데 그 목적이 있다.The present invention has been made in view of the above point, to effectively remove the high heat generated from the light emitting diode, and to provide a vehicle light emitting diode bulb that is easily mounted on the socket of various types of vehicle lamps. The purpose is.

In addition, the heat dissipation member 5 is made of the same aluminum material as the lower case 7 to be described later to effectively dissipate heat generated from the light emitting diodes 3 to be described later, the heat dissipation member 5 A plurality of heat dissipation fins 5a are integrally formed on the side thereof to provide a wider heat dissipation area, and a coupling jaw 5b to which the lens 1 to be described later is coupled is formed at an upper edge thereof.

다수의 회전결합돌기(6)는 열발산부재(5)의 방열핀(5a)이 형성된 상부측 외주면 상에 분리가능하게 장착되고, 이를 보다 상세히 살펴보면 열발산부재(5)의 방열핀(5a)이 형성된 상부측 외주면 상에 스크류탭 형상의 장착공(미도시)이 다수개 형성된 상태에서 이 장착공(미도시) 상에 수나사부를 구비한 회전결합돌기(6)가 차량용 램프의 반사경(미도시)에 대응되도록 선택적으로 장착됨으로써, 차량용 램프의 반사경(미도시) 후면측에 회전결합되도록 구성된다. 이 회전결합돌기(6)는 종래의 차량용 램프의 반사경(미도시)에 회전결합되는 소켓의 니플에 해당된다.The plurality of rotary coupling protrusions 6 are detachably mounted on the upper circumferential surface on which the heat dissipation fins 5a of the heat dissipation member 5 are formed, and in more detail, the heat dissipation fins 5a of the heat dissipation member 5 are formed.

A plurality of convex patterns (not shown, see the applicant's pre-registration design) may be formed to prevent glare that may occur when.

또한, 렌즈(1)의 상부측에는 반사캡(2)을 더 구비하여, 발광 다이오드(3)로부터 조사되는 빛을 차량용 램프의 반사경(미도시)측으로 반사시킴으로써 광원이 직접 조사됨에 따라 발생할 수 있는 눈부심을 방지할 수 있다.In addition, the upper side of the lens (1) is further provided with a reflective cap 2, by reflecting the light emitted from the light emitting diode (3) to the reflector (not shown) side of the vehicle lamp glare that may occur when the light source is directly irradiated Can be prevented.

대안적으로, 렌즈(1)는 도 3에 도시된 바와 같이, 그 전면 내측면에 발광다이오드(3)로부터 나오는 빛을 증폭시켜 전방으로 조사할수 있도록 볼록면(1a)을 구비한 형태로 이루어질 수도 있다.Alternatively, as shown in FIG. 3, the lens 1 may have a convex surface 1a on the inner surface of the front surface thereof so as to amplify the light emitted from the light emitting diodes 3 and irradiate it forward. have.

하부 케이스(7)는 도시된 바와 같이, 통상적인 전구의 케이스 형태와 유사하고, 상부는 개방되며, 후술하는 발광 다이오드(3)로부터 발생하는 열을 외부로 효과적으로 발산하도록 알루미늄 재질로 이루어진다. 이 하부 케이스(7)는 그 하부면 상에 차량용 램프의 소켓(미도시) 상에 돌려 끼워질 수 있도록 리벳(7a)이 구비되고, 그 하단면에 적어도 하나 이상의 (+)극 단자(7b)가 형성된다.The lower case 7 is similar to the case form of a conventional bulb, as shown, and the upper part is open, and is made of aluminum to effectively dissipate heat generated from the light emitting diodes 3 described later to the outside. The lower case 7 is provided with a rivet 7a on its lower surface so as to be screwed onto a socket (not shown) of a vehicle lamp, and at least one (+) pole terminal 7b on its lower surface. Is formed.

한편, 열발산부재(5) 및 하부 케이스(7)가 전열성이 높은 알루미늄 재질로 이루어져 있으므로, 발광다이오드(3)로부터 발생되는 열로 인해 빛의 밝기가 약해지고, 파장의 변화로 인해 색이 변화되는 것을 방지할 수 있으며, 더 나아가 발광다이오드(3)의 수명을 보다 연장할 수 있다.On the other hand, since the heat dissipation member 5 and the lower case 7 is made of a high heat transfer aluminum material, the brightness of the light is weakened by the heat generated from the light emitting diodes 3, and the color is changed due to the change of the wavelength.
