이하, 본 발명의 구성을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명의 LED(20)와 도광판(30)의 결합구조를 나타낸 사시도로서, 도광판(30)의 형태는 사출성형 가능한 반투명 또는 열가소성 합성수지재로 이루어 지고 LED의 빛을 수광하는 부위(31)는 등각으로 경사진 형태를 가지고 있다.Figure 2 is a perspective view showing a coupling structure of the LED 20 and the light guide plate 30 of the present invention, the shape of the light guide plate 30 is made of a semi-transparent or thermoplastic synthetic resin material capable of injection molding, and the part receiving the light of the LED (31) ) Has an isometric slope.
이러한 도광판(30)의 수광부(31)에 LED(20)가 일체로 사출성형되어 구조적으로 일체화 되어 있다.The LED 20 is integrally injection molded to the light receiving unit 31 of the light guide plate 30 to be structurally integrated.
한편, 상기 도광판(30)에 일체화 되는 LED(20)는 사출성형시 열에 결딜 수 있는 재질로 형성되고 그 양측부에 내부식성 강선으로 이루어진 솔더 단자(21)가 결합되어 있는 구조이다.Meanwhile, the LED 20 integrated into the light guide plate 30 is formed of a material capable of resisting heat during injection molding, and has solder structures 21 formed of corrosion resistant steel wires at both sides thereof.
본 발명은 상기와 같이 일체화된 도광판(30)을 PCB(10)상에 위치하여 솔더 단자(21)를 솔더링하면 최종적인 조립작업이 완료된다.In the present invention, when the integrated light guide plate 30 is placed on the PCB 10 and the solder terminal 21 is soldered, final assembly work is completed.
상기와 같은 본 발명의 LED(20)와 도광판(30)의 결합구조에 의하면 도광판(30)에 LED(20)가 구조적으로 일체화 되어 있으므로 기존의 공간에 의한 빛의 손실을 방지할 수 있고 구조적으로도 안정된 상태이다.According to the coupling structure of the LED 20 and the light guide plate 30 of the present invention as described above, since the LED 20 is structurally integrated in the light guide plate 30, it is possible to prevent the loss of light due to the existing space and It is also in a stable state.

이상에서 살펴 본 바와 같이 본 발명은 자체 발광 기능이 없는 액정 디스플레이의 배광(背光)을 위한 백라이트(Back Light)에서 광원(光源)을 형성하는 LED와 빛의 균일한 확산을 위한 도광판을 사출성형시 일체화 함으로써 조립의 간편성 및 구조적 안정성을 부여할 수 있다.As described above, the present invention is an injection molding process for LEDs forming a light source in a backlight for light distribution of a liquid crystal display without a self-luminous function and a light guide plate for uniform diffusion of light. By integrating, it is possible to provide simplicity of assembly and structural stability.
또한, LED와 도광판의 간극(間隙)을 배제함으로써 빛의 손실을 방지하여 보다 밝은 디스플레이 환경을 구현할 수 있는 효과가 있다.In addition, by eliminating the gap between the LED and the light guide plate, it is possible to prevent the loss of light to implement a brighter display environment.
