Description

차량용 램프 장치{A lamp apparatus for vehicles}[0001] The present invention relates to a lamp apparatus for vehicles,

본 발명은 차량용 램프 장치에 관한 것으로, 보다 상세하게는 렌즈에 균일한 이미지를 구현하기 위한 차량용 램프 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp unit for a vehicle, and more particularly, to a lamp unit for a vehicle for realizing a uniform image on a lens.

일반적으로 램프는 배터리 등으로부터 전원을 공급받아 빛을 발생시키는 장치로서, 자동차에 설치되는 차량용 램프 장치는 전방으로 빛을 조사함으로써, 운전자의 시야를 확보하도록 한다. 차량용 램프 장치의 광원으로는 보통 할로겐 램프나 가스방전식 램프를 주로 사용하였다. 그러나 최근에는 전력소모가 적으면서, 밝기가 뛰어난 LED(Light Emitting Diode)를 광원으로 많이 사용하고 있다.Generally, a lamp is a device that generates power by receiving power from a battery or the like, and a vehicular lamp device installed in a vehicle irradiates light forward to secure a driver's view. Halogen lamps or gas discharge lamps are mainly used as light sources for automotive lamp units. In recent years, however, LEDs (Light Emitting Diodes) having excellent brightness have been widely used as light sources while consuming less power.

또한, LED의 경우, 사이즈를 최소화함으로써 램프의 디자인 자유도를 높여줄 뿐만 아니라 반영구적인 수명으로 인해 경제성도 갖추고 있다.In addition, in the case of LEDs, the size is minimized to increase the degree of design freedom of the lamp, and it is also economical due to the semi-permanent lifetime.

이런 LED를 광원으로 사용하는 램프의 경우, 일반적으로 2가지의 방식으로 사용되고 있다.Lamps using such LEDs as light sources are generally used in two ways.

먼저, LED를 광축방향과 반사면의 광축방향과 동일하게 적용하는 직광 조명방식과 LED를 반사면의 광축에 90도로 배치하는 간접 조명방식이 있다.First, there are an orthodontic illumination system in which the LED is applied in the same direction as the optical axis direction and the optical axis direction in the reflection plane, and an indirect illumination system in which the LED is arranged at 90 degrees on the optical axis of the reflection plane.

직광 조명방식은 LED 광도에 의한 중앙부에 HOT ZONE이 발생한다. 또한, LED 주위는 상대적으로 어두우며, 렌즈 발광면적이 반사면의 오프닝 면적과 동일하여 LED의 수량을 증가시키는 문제점이 있었다.In the case of the direct lighting method, the HOT zone occurs in the center part due to the LED brightness. Further, the periphery of the LED is relatively dark, and the lens emission area is the same as the opening area of the reflection surface, thereby increasing the number of LEDs.

또한, 간접 조명방식은 반사면의 광축과 90도 방향으로 LED를 배치하여 LED의 HOT ZONE에 대한 이미지는 감소한다. 하지만, 간접 조명방식도 반사면의 오프닝 면적에 의해 LED 수량이 증가하는 문제점이 있었다.In addition, the indirect illumination method arranges the LEDs in the direction of 90 degrees with the optical axis of the reflection surface, so that the image for the HOT zone of the LED decreases. However, there is a problem that the indirect light method also increases the LED quantity due to the opening area of the reflecting surface.

본 발명이 해결하고자 하는 과제는 반사면의 중간 부분을 볼록하게 형성하여 렌즈에 균일한 이미지를 구현하고자 하는 것이다.A problem to be solved by the present invention is to form an intermediate portion of a reflective surface in a convex shape to realize a uniform image on the lens.

본 발명의 과제들은 이상에서 언급한 과제들로 제한되지 않으며, 언급되지 않은 또 다른 과제들은 아래의 기재로부터 당업자에게 명확하게 이해될 수 있을 것이다.The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.

상기 과제를 달성하기 위하여, 본 발명의 실시예에 따른 차량용 램프 장치는 빛을 투과시키는 렌즈와; 상기 렌즈의 중앙부에 배치되고, 빛을 투과시키지 않는 베즐과; 상기 베즐의 후방에 결합되고, 후방으로 빛을 조사하는 광원부와; 상기 광원부의 후방에 배치되고, 상기 광원부에서 조사되는 빛을 전방으로 반사시키는 반사면를 포함하고, 상기 반사면은 상기 렌즈와 대응되는 면이 전방으로 경사지게 형성되는 경사부와; 상기 베즐과 대응되는 면이 전방으로 볼록한 곡면으로 형성되어, 조사된 빛을 확산시키는 곡면부를 포함한다.According to an aspect of the present invention, there is provided a vehicular lamp unit including: a light-transmitting lens; A bezel disposed at a central portion of the lens and not transmitting light; A light source coupled to the rear of the bezel and configured to irradiate light backward; And a reflecting surface that is disposed behind the light source and reflects light emitted from the light source forward, wherein the reflecting surface has an inclined portion formed by inclining the surface corresponding to the lens forward; And a surface corresponding to the bezel is formed into a curved surface that is convex forward, and includes a curved surface portion for diffusing the irradiated light.

기타 실시예들의 구체적인 사항들은 상세한 설명 및 도면들에 포함되어 있다. The details of other embodiments are included in the detailed description and drawings.

본 발명의 차량용 램프 장치에 따르면 다음과 같은 효과가 하나 혹은 그 이상 있다.According to the lamp unit for a vehicle of the present invention, one or more of the following effects can be obtained.

첫째,　광원부 중심의 높은 광도에 의한 HOT ZONE 이미지를 감소시켜 렌즈에 균일한 이미지 구현이 가능한 장점이 있다.First, there is an advantage that a uniform image can be realized in the lens by reducing the HOT ZONE image due to the high light intensity in the center of the light source.

둘째,　일정 광도를 발생시키는 광원부의 경우, 위치고정을 위한 부품을 삭제할 수 있어 중량을 감소시키는 장점도 있다.Secondly, in the case of a light source generating a certain luminous intensity, it is possible to eliminate components for fixing the position, thereby reducing weight.

셋째,　하나의 광원으로 상하부 이미지를 구현함으로써 사용 광원의 수량을 줄여 비용을 절감할 수 있는 장점도 있다.Third, by implementing upper and lower images as a single light source, it is possible to reduce the number of used light sources, thereby reducing costs.

본 발명의 효과들은 이상에서 언급한 효과들로 제한되지 않으며, 언급되지 않은 또 다른 효과들은 청구범위의 기재로부터 당업자에게 명확하게 이해될 수 있을 것이다.The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

이하, 본 발명의 실시예들에 의하여 차량용 램프 장치(100)를 설명하기 위한 도면들을 참고하여 본 발명에 대해 설명하도록 한다.Hereinafter, the present invention will be described with reference to the drawings for explaining a lamp unit 100 for a vehicle according to embodiments of the present invention.

도 1은 본 발명의 일 실시예에 따른 차량용 램프 장치가 장착된 차량의 일부분을 나타낸 도면이다. 1 is a view showing a part of a vehicle equipped with a lamp unit for a vehicle according to an embodiment of the present invention.

도 1을 참조하면, 본 발명의 일 실시예에 따른 차량용 램프 장치(100)는 차량의 전방에 장착된다. 따라서, 밤에 차량의 전방을 밝혀주어 운전자가 안전하게 차량을 주행할 수 있도록 한다. 다만, 본 발명의 다른 실시예에서는 차량의 후방에 장착되어 후미등과 같은 역할을 할 수도 있다.Referring to FIG. 1, a vehicle lamp apparatus 100 according to an embodiment of the present invention is mounted in front of a vehicle. Therefore, the front of the vehicle is illuminated at night so that the driver can safely drive the vehicle. However, in another embodiment of the present invention, it may be mounted on the rear of the vehicle to serve as a tail lamp.

차량용 램프 장치(100)는 렌즈(110), 베즐(120), 광원부(130)와 반사면(140)을 포함한다. 자세한 사항은 도 2를 참조하여 후술한다.The vehicular lamp device 100 includes a lens 110, a bezel 120, a light source 130, and a reflecting surface 140. Details will be described later with reference to Fig.

렌즈(110)는 원형상으로 형성되며, 광원부(130)에서 조사된 빛을 투과시킨다. 다만, 본 발명의 다른 실시예에서는 렌즈(110)는 타원형, 사각형, 삼각형 등으로 형성될 수 있다.The lens 110 is formed in a circular shape and transmits light irradiated from the light source unit 130. However, in another embodiment of the present invention, the lens 110 may be formed in an elliptical shape, a square shape, a triangular shape, or the like.

베즐(120)은 렌즈(110)의 중앙에 배치되고, 원형으로 형성된다. 또한, 베즐(120)은 빛을 투과시키지 않기에, 렌즈(110)를 통해 투과되는 빛은 도넛모양을 형성하게 된다. 다만, 본 발명의 다른 실시예에서는 베즐(120)은 타원형 등으로 형성될 수도 있다.The bezel 120 is disposed at the center of the lens 110 and is formed in a circular shape. In addition, since the bezel 120 does not transmit light, the light transmitted through the lens 110 forms a donut shape. However, in another embodiment of the present invention, the bezel 120 may be formed in an elliptical shape or the like.

베즐(120)은 후술할 엘이디(LED) 소자(132)의 성능을 고려하여 폭을 크기를 조절하는 것이 바람직하다. 따라서, 엘이디(LED) 소자(132)의 성능이 떨어진다면, 베즐(120)의 폭을 작게 하는 것이 바람직하다.The width of the bezel 120 is preferably adjusted in consideration of the performance of an LED element 132 to be described later. Therefore, if the performance of the LED element 132 deteriorates, it is preferable to reduce the width of the bezel 120.

도 2는 도 1의 A-A의 단면도를 나타낸 도면이다.Fig. 2 is a sectional view taken along the line A-A in Fig.

도 2를 참조하면, 차량용 램프 장치(100)는 렌즈(110), 베즐(120), 광원부(130)와 반사면(140)을 포함한다.Referring to FIG. 2, the vehicular lamp system 100 includes a lens 110, a bezel 120, a light source 130, and a reflecting surface 140.

렌즈(110)는 반사면(140)을 통해 반사된 빛을 투과시킨다. 따라서, 렌즈(110)의 형상에 따라 투과된 빛의 모양은 달라진다.The lens 110 transmits the light reflected through the reflecting surface 140. Accordingly, the shape of the transmitted light differs depending on the shape of the lens 110.

베즐(120)은 렌즈(110)의 후방면에 결합되며, 렌즈(110)의 중앙부에 배치된다. 또한, 베즐(120)은 후방에 광원부(130)가 결합된다.The bezel 120 is coupled to the rear surface of the lens 110 and disposed at the center of the lens 110. In addition, the light source unit 130 is coupled to the rear of the bezel 120.

베즐(120)은 원형상으로 이루어지며, 빛을 투과시키지 않기 때문에, 본 실시예에서는 렌즈(110)를 투과한 빛은 도넛모양을 형성한다.Since the bezel 120 has a circular shape and does not transmit light, the light transmitted through the lens 110 forms a donut shape in this embodiment.

또한, 베즐(120)은 크기는 후술할 반사면(140)의 곡면부(142)와 동일하게 형성된다. 다만, 본 발명의 다른 실시예에서는 광원부(130)의 성능에 따라 베즐(120)의 크기가 달라질 수 있다.The size of the bezel 120 is formed to be the same as the curved surface portion 142 of the reflecting surface 140 to be described later. However, in another embodiment of the present invention, the size of the bezel 120 may be changed according to the performance of the light source 130.

광원부(130)는 베즐(120)의 후방에 결합되고 후방으로 빛을 조사한다. 광원부(130)는 빛을 발생시키는 엘이디(LED) 소자(132)와 인쇄회로기판(131)을 포함한다.The light source unit 130 is coupled to the rear of the bezel 120 and irradiates light backward. The light source unit 130 includes an LED (light emitting diode) element 132 for generating light and a printed circuit board 131.

인쇄회로기판(131)은 배즐의 후방에 결합되고, 광원부(130)는 인쇄회로기판(131)에 장착된다. 인쇄회로기판(131)이 수직 방향으로 배치되므로 엘이디(LED) 소자(132)로부터 조사되는 빛은 수평방향으로 조사된다. 또한, 엘이디(LED) 소자(132)는 인쇄회로기판(131)의 중앙부에 배치된다.The printed circuit board 131 is coupled to the back of the jig and the light source unit 130 is mounted on the printed circuit board 131. Since the printed circuit board 131 is arranged in the vertical direction, the light emitted from the LED device 132 is irradiated in the horizontal direction. The LED element 132 is disposed at the center of the printed circuit board 131.

광원부(130)는 후술할 반사면(140)의 곡면부(142)와 평행하게 배치된다. 다만, 본 발명의 다른 실시예에서는 광원부(130)는 후술할 곡면부(142)와 경사지게 배치될 수도 있다.The light source unit 130 is disposed in parallel with the curved surface portion 142 of the reflection surface 140 to be described later. However, in another embodiment of the present invention, the light source 130 may be inclined with respect to the curved surface 142, which will be described later.

광원(130)는 베즐(120)에 결합되는바, 렌즈(110)의 중앙부분에 배치된다. 따라서, 후술할 반사면(140)의 곡면부(142)와 경사부(141)에 의해 광원부(130)를 최소화하여 이미지를 구현시킬 수 있다.The light source 130 is coupled to the bezel 120 and is disposed at a central portion of the lens 110. Therefore, the light source unit 130 can be minimized by the curved surface portion 142 and the inclined portion 141 of the reflection surface 140, which will be described later, to realize an image.

반사면(140)은 광원부(130)의 후방에 배치되고, 광원부(130)에서 조사되는 빛을 전방으로 반사시킨다. 따라서, 본 발명은 간접 조명방식으로 분류된다.The reflecting surface 140 is disposed behind the light source unit 130 and reflects the light emitted from the light source unit 130 forward. Therefore, the present invention is classified into an indirect lighting method.

반사면(140)은 렌즈(110)와 대응되는 면이 전방으로 경사지게 형성되는 경사부(141)와 베즐(120)과 대응되는 면이 전방으로 볼록한 곡면으로 형성되는 곡면부(142)를 포함한다.The reflective surface 140 includes an inclined portion 141 having a surface corresponding to the lens 110 and a curved surface portion 142 having a curved surface that is convex on the surface corresponding to the bezel 120 .

경사면은 경사면과 대응되는 렌즈(110)로 빛을 집광시키고, 곡면부(142)는 광원부(130)에서 조사된 빛을 확산시킨다. 따라서, 렌즈(110)에 균일한 이미지를 구현한다.The inclined surface condenses light with the lens 110 corresponding to the inclined surface, and the curved surface portion 142 diffuses the light irradiated from the light source unit 130. [ Thus, a uniform image is realized on the lens 110. [

상기와 같이 구성되는 본 발명에 따른 차량용 램프 장치(100)의 작용을 설명하면 다음과 같다.The operation of the vehicular lamp apparatus 100 according to the present invention will now be described.

먼저, 차량의 시동 또는 램프 장치(100)에 전기를 인가하면, 전기를 인가받은 광원부(130)는 후방에 배치된 반사면(140)으로 빛을 조사한다. First, when the vehicle is started or electricity is applied to the lamp unit 100, the light source unit 130 to which electricity is applied irradiates light to the reflective surface 140 disposed at the rear.

빛은 반사면(140)의 경사부(141)와 곡면부(142)에 도달하게 된다. 이에 경사부(141)는 빛을 경사부(141)에 대응되는 렌즈(110)부분으로 집광시키며, 곡면부(142)는 빛을 렌즈(110)로 확산시킨다. The light reaches the inclined portion 141 of the reflecting surface 140 and the curved surface portion 142. The inclined portion 141 condenses the light into a portion of the lens 110 corresponding to the inclined portion 141 and the curved portion 142 diffuses the light into the lens 110.

집광되고 확산된 빛은 렌즈(110)를 투과하여 램프 장치(100)의 전방으로 확산된다. 다만, 빛은 베즐(120)을 투과하지 못하므로 투과된 빛은 도넛모양을 형성하게 된다.The condensed and diffused light passes through the lens 110 and diffuses toward the front of the lamp unit 100. However, since the light can not pass through the bezel 120, the transmitted light forms a donut shape.

또한, 곡면부(142)는 빛을 확산시키는바, 렌즈(110)를 투과시키는 빛의 양을 증대시킨다.Further, the curved surface portion 142 diffuses light, which increases the amount of light transmitting through the lens 110.
