Description

차량용 LED 램프 모듈Car LED Lamp Module
본 발명은 차량용 LED 램프 모듈에 대한 것으로서, 상세하게는 기존의 차량용 할로겐램프와 거의 동일한 배광 및 고휘도 구현이 가능한 차량용 LED 램프 모듈에 관한 것이다.The present invention relates to a vehicle LED lamp module, and more particularly to a vehicle LED lamp module capable of realizing the same light distribution and high brightness as a conventional vehicle halogen lamp.
차량용 전조등이나 안개등(이하 '차량용 헤드램프'로 통칭함)은 차량의 전방 진로를 비춰주는 기능을 수행하는 조명으로서 차량의 전방 양측 영역에 구비된다. Vehicle headlights and fog lights (hereinafter referred to as 'vehicle headlamps') are lights that perform a function of illuminating the front path of the vehicle and are provided in both front areas of the vehicle.
종래 차량용 헤드램프는 광을 차량의 전방으로 반사 집광시키기 위한 반사면을 갖는 하우징과, 하우징에 탈착 가능하게 장착되어 전원공급에 의해 광을 발산하는 광원 모듈을 포함하고 있다. 이때, 광원 모듈은 하우징의 후방 측에 형성된 램프 장착홀에 램프가 삽입되는 형태로 착탈 가능하게 결합된다. Conventional vehicle headlamps include a housing having a reflective surface for reflecting and condensing light toward the front of the vehicle, and a light source module detachably mounted to the housing to emit light by power supply. At this time, the light source module is detachably coupled in the form that the lamp is inserted into the lamp mounting hole formed in the rear side of the housing.
이러한 광원 모듈은 광원으로서 할로겐램프를 주로 이용하였지만, 최근 전력소모 및 수명에 있어서 기존 할로겐램프보다 큰 장점을 가지고 있는 LED(Light Emitting Diode)를 광원으로 하는 차량용 LED 램프 모듈이 주목받고 있다. The light source module mainly uses a halogen lamp as a light source, but in recent years, a vehicle LED lamp module using an LED (Light Emitting Diode), which has a great advantage over the existing halogen lamp in power consumption and life is attracting attention.
종래 차량용 LED 램프 모듈(101)의 일예가 도 1에 도시되어 있다. 이 도면에 도시된 바와 같이, 종래 차량용 LED 램프 모듈(101)은 헤드램프 하우징(도 5 및 도 6의 '5'참고)에 착탈 가능하게 결합되는 하우징결합부(110)와, 하우징결합부(110)의 전방에 마련되어 하우징(도 5 및 도 6의 '5'참고) 내부에서 전원공급에 의해 차량의 전방을 향해 광을 발산하는 LED광원부(120)와, 하우징결합부(110) 후방에 마련되어 하우징(도 5 및 도 6의 '5'참고) 외부에 위치하며 LED광원부(120)에서 발생하는 발열을 방열하는 방열부(130)를 가지고 있다. An example of a conventional vehicle LED lamp module 101 is shown in FIG. 1. As shown in this figure, the conventional vehicle LED lamp module 101 is a housing coupling portion 110 and a housing coupling portion (110) detachably coupled to the headlamp housing (see '5' of FIGS. 5 and 6) It is provided at the front of the 110 is provided in the housing (see '5' of Fig. 5 and 6) LED light source unit 120 for emitting light toward the front of the vehicle by the power supply, and the housing coupling unit 110 is provided in the rear Located outside the housing (see '5' in FIGS. 5 and 6) and has a heat dissipation unit 130 for radiating heat generated from the LED light source unit 120.
이와 같은 종래 차량용 LED 램프 모듈(101)은 LED광원부(120)에서 발생되는 고온의 발열이 방열부(130)로 열전도되면서 열교환이 이루어지며, LED광원부(120)에서 발산된 빛 중 전방을 향하지 못하고 사방으로 분산되는 빛이 헤드램프 하우징(도 5 및 도 6의 '5'참고)의 반사면에서 반사되어 차량의 전방으로 집광된다. Such a conventional vehicle LED lamp module 101 is heat exchanged as the high temperature heat generated from the LED light source unit 120 is thermally conducted to the heat dissipation unit 130, and does not face the front of the light emitted from the LED light source unit 120. Light scattered in all directions is reflected from the reflecting surface of the headlamp housing (refer to '5' in FIGS. 5 and 6) and is focused toward the front of the vehicle.
한편, 차량용 헤드램프의 배광은 마주 오는 차량의 운전자 시야에 방해되지 않는 형태로 형성되어야 한다. 현재 널리 이용되는 로우빔용 할로겐램프를 이용한 차량용 헤드램프는 도 7에 나타낸 바와 같은 배광이 형성된다. On the other hand, the light distribution of the vehicle headlamp should be formed in a shape that does not interfere with the driver's view of the oncoming vehicle. In a vehicle head lamp using a low beam halogen lamp which is widely used at present, light distribution as shown in FIG. 7 is formed.
그러나 종래 차량용 LED 램프 모듈을 이용할 경우, 할로겐램프와 같은 배광이 나올 수 없게 된다. However, when using a conventional vehicle LED lamp module, light distribution such as a halogen lamp may not come out.
왜냐하면, 할로겐램프에서 광이 발산되는 방향은 360도 방향인 것에 비하여, 종래 차량용 LED 램프 모듈은 LED광원부가 지지부의 일면에 부착된 형태이면서 LED 램프 모듈의 광 발산 방향이 120도 범위이기 때문에, 할로겐램프와 같은 배광을 구현할 수 없는 것이다. This is because the direction in which light is emitted from the halogen lamp is 360 degrees, whereas in the conventional vehicle LED lamp module, since the LED light source is attached to one surface of the support portion, the light emitting direction of the LED lamp module is in the range of 120 degrees. It is impossible to implement light distribution like a lamp.
더불어 종래 차량용 LED 램프 모듈은 하우징의 반사면에서 반사되는 빛이 사방으로 반사되면서 빛의 반사각이 흩어지게 되어 난반사가 발생된다. 이에 의해, 차량 전방을 향한 빛의 집광효율이 저하되어 차량용 LED 램프 모듈의 휘도 저하의 원인이 될뿐만 아니라. 난반사에 의해 배광이 사방으로 퍼지면서 반대편에서 마주 오는 차량의 운전자에게 눈부심을 제공하는 문제점이 있다.In addition, in the conventional LED lamp module for the vehicle, the light reflected from the reflective surface of the housing is reflected in all directions, so that the reflection angle of the light is scattered and diffuse reflection occurs. Thereby, the light condensing efficiency of the light toward the front of the vehicle is lowered, which not only causes a decrease in the brightness of the vehicle LED lamp module. There is a problem of providing glare to the driver of the vehicle coming from the opposite side as the light distribution spreads in all directions by the diffuse reflection.
따라서 본 발명의 목적은 할로겐램프와 거의 동일한 배광 형태를 구현함과 동시에, 고휘도의 차량용 LED 램프 모듈을 제공하는 것이다. Accordingly, an object of the present invention is to provide a high-brightness automotive LED lamp module while at the same time realizing the same light distribution form as the halogen lamp.
또한 난반사가 최소화되어 마주 오는 차량 운전자의 눈부심을 방지할 수 있는 차량용 LED 램프 모듈을 제공하는 것이다.In addition, it is to provide a vehicle LED lamp module that can prevent the glare of the oncoming vehicle driver to minimize the diffuse reflection.

그리고 상기 각 LED광원의 LED소자는 한 쌍으로 마련될 수 있다. In addition, the LED device of each LED light source may be provided in pairs.
또한, 상기 중심광원결합면에 배치되는 LED소자는 상기 중심에 위치하며, 상기 양 측면광원결합면에 위치하는 LED소자는 상기 중심에 대해 0mm 내지 8mm 간격을 두고 위치하는 것이 바람직하다. In addition, the LED device disposed on the center light source coupling surface is located in the center, the LED device located on both side light source coupling surface is preferably located at 0mm to 8mm intervals with respect to the center.
또한, 상기 양 측면광원결합면은 3mm 내지 10mm 간격을 두고 상기 중심광원결합면 양측에 형성되는 것이 효과적이다.In addition, both side light source coupling surface is effective to be formed on both sides of the center light source coupling surface at intervals of 3mm to 10mm.
그리고 상기 각 광원결합면은 0mm 내지 4mm 함몰된 것이 바람직하다. And each of the light source coupling surface is preferably 0mm to 4mm recessed.
한편, 상기 광원열전도지지부의 자유단부에는 상기 LED광원으로부터 발생되는 빛이 전방으로 난반사되는 것을 차단하는 전방차단부가 구비되는 것이 보다 바람직하다.On the other hand, the free end of the light source heat conduction support portion is more preferably provided with a front blocking portion for preventing the light generated from the LED light source is diffusely reflected forward.
