이하, 본 고안의 일 실시예를 도면을 참조하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

도 1은 본 고안의 조명장치의 정면 사시도이고, 도 2는 본 고안의 조명장치의 배면 사시도를 나타낸 것이다.1 is a front perspective view of the lighting apparatus of the present invention, Figure 2 shows a rear perspective view of the lighting apparatus of the present invention.

도 1에 도시된 바와 같이, 본 고안은 LED(10)와, LED(10)로부터 방출된 빛을 모으는 수광부재(20)와, LED(10)의 빛을 외부로 방출하는 노광면(31)을 포함하는 반사부재(30)를 포함하여 구성된다.As shown in FIG. 1, the present invention provides an LED 10, a light receiving member 20 that collects light emitted from the LED 10, and an exposure surface 31 that emits light of the LED 10 to the outside. It is configured to include a reflection member 30 including a.

LED(10)는 발광소자의 일종으로, PCB(미도시) 상에서 수광부재(20)의 말단에 각각 배치된다.The LED 10 is a kind of light emitting device, and is disposed at each end of the light receiving member 20 on a PCB (not shown).

본 고안에서는 PCB 상에 2개의 수광부재(20)가 원형을 이루면서 설치됨에 따라서 LED(10)도 2개가 각각 설치된다.In the present invention, as the two light receiving members 20 are installed in a circular shape on the PCB, two LEDs 10 are also installed.

수광부재(20)는 LED(10)로부터 방출되는 빛을 모으는 것으로서 PCB 상에 배치된다.The light receiving member 20 is disposed on the PCB as collecting light emitted from the LED 10.

도 2에 도시된 바와 같이, 수광부재(20)는 LED(10)로부터 방출되는 빛을 모으로 이 빛이 수광부재(20)의 벽을 따라서 굴절될 수 있도록 일정각도로 굽어진 와형으로 형성된다.As shown in FIG. 2, the light receiving member 20 is formed into a vortex bent at an angle so that the light can be refracted along the wall of the light receiving member 20 by collecting the light emitted from the LED 10. .

각각 구부러진 와형의 수광부재(20) 2쌍은 서로 맞대게 되면 원형으로 이루어 지도록 형성된다.Two pairs of curved light receiving members 20 each bent are formed to be circular when they face each other.

수광부재(20)의 말단에 각각 LED(10)가 배치되고, LED(10)에서 방출되는 빛 은 굽어진 수광부재(20)의 형상을 따라서 굴절되게 된다.LEDs 10 are disposed at ends of the light receiving members 20, and the light emitted from the LEDs 10 is refracted along the shape of the curved light receiving members 20.

그리고, 수광부재(20)는 말단에서 와형의 중심으로 갈수록 그 폭이 점점 줄어들게 형성된다.In addition, the light receiving member 20 is formed such that its width gradually decreases from the end toward the center of the vortex.

즉, 수광부재의 말단에서의 폭(ta)이 가장 크게 형성되고, 수광부재의 와형의 중심에서의 폭(tb)이 가장 작게 형성된다.That is, the width t a at the end of the light receiving member is formed largest, and the width t b at the center of the vortex of the light receiving member is formed smallest.

수광부재의 말단에서 수광부재의 와형의 중심으로 향하면서 일정하게 그 폭이 줄어들게 수광부재(20)는 형성된다.The light receiving member 20 is formed so that its width is uniformly reduced from the end of the light receiving member toward the center of the vortex of the light receiving member.

이것은 수광부재(20)의 말단에 배치된 LED(10)로부터 방출되는 빛이 멀어질수록 조도가 약해지게 되므로, 수광부재(20)의 폭을 점점 줄여서 단면적의 크기를 줄어들게 하여 LED(10)로부터 방출되는 빛이 균일한 조도를 이룰 수 있게 한다.Since the light emitted from the LED 10 disposed at the distal end of the light receiving member 20 decreases in intensity, the width of the light receiving member 20 is gradually reduced to reduce the size of the cross-sectional area from the LED 10. It ensures that the emitted light has a uniform illuminance.

반사부재(30)는 수광부재(20)의 상부에 위치하는 사각형의 판재로서, LED(10)로부터 방출된 빛이 수광부재(20)를 지나서 반사부재(30)의 상부에 형성된 노광면(31)을 통하여 외부로 빛을 방출하게 된다.The reflective member 30 is a rectangular plate positioned on the light receiving member 20, and the light emitted from the LED 10 passes through the light receiving member 20 to the upper surface of the reflective member 30. ) To emit light to the outside.

여기서, 노광면(31)은 볼륨노브의 외주면의 형상에 따라서 형성되며, 볼륨노브의 외주면을 따라서 빛을 방출하게 된다.Here, the exposure surface 31 is formed according to the shape of the outer peripheral surface of the volume knob, and emits light along the outer peripheral surface of the volume knob.

이러한 구성요소로 이루어진 본 고안의 조립과정을 살펴보면 다음과 같다.Looking at the assembly process of the present invention consisting of these components are as follows.

먼저, PCB(미도시) 상에 수광부재(20) 각각 2쌍을 서로 원형을 이루도록 맞춘다.First, each pair of light receiving members 20 on a PCB (not shown) is fitted to form a circle with each other.

각각의 수광부재(20)의 말단에 LED(10)를 각각 배치한다.The LEDs 10 are disposed at ends of the respective light receiving members 20.

그리고, 수광부재(20)의 상부에 사각형의 반사부재(30)를 설치한다.Then, a rectangular reflective member 30 is provided on the light receiving member 20.

이때, LED(10)의 빛을 외부로 방출하는 노광면(31)은 볼륨노브의 외주면에 맞게 외부를 향하여 배치된다.At this time, the exposure surface 31 for emitting the light of the LED 10 to the outside is disposed toward the outside in accordance with the outer peripheral surface of the volume knob.

한편, 본 고안의 작동과정을 살펴보면 다음과 같다.On the other hand, look at the operation of the present invention as follows.

먼저, AV 기기에 전원이 들어오면, LED(10)로부터 방출된 빛은 수광부재(20)의 형상에 따라서 굴절된다.First, when power is supplied to the AV device, the light emitted from the LED 10 is refracted according to the shape of the light receiving member 20.

LED(10)로부터 방출되는 빛은 수광부재(20)의 폭의 일정한 변형에 따라서 균일한 조도를 유지하게 된다.The light emitted from the LED 10 maintains uniform illuminance according to a constant deformation of the width of the light receiving member 20.

그리고, 이 LED(10)의 빛은 수광부재(20)을 지나서 상부에 위치하는 반사부재(30)의 노광면(31)을 통하여 볼륨노브의 외주면을 균일한 조도로 방출하게 된다.The light of the LED 10 emits the outer circumferential surface of the volume knob with uniform illuminance through the exposure surface 31 of the reflective member 30 positioned above the light receiving member 20.

본 고안은 상기 실시예에 한정되지 않으며, 많은 변형이 본 고안의 사상 내에서 당 분야에서 통상의 지식을 가진 자에 의하여 가능함은 물론이다.The present invention is not limited to the above embodiments, and many variations are possible by those of ordinary skill in the art within the spirit of the present invention.
