It relates to the structure of the ultra-thin 7 segment used.

일반적으로 엘이디를 이용한 디스플레이라 함은 인간의 시각에 호소하는 일종의 정보전달장치로서 이는 계기판 및 가전제품에 장착되어 전기적 발광기능에 의해 다양한 형태의 문자나 숫자를 표현하며 정보전달의 매개체로 이용되는 것이다.In general, a display using an LED is a kind of information transmission device that appeals to the human vision. It is mounted on the instrument panel and home appliances, and expresses various forms of letters or numbers by an electric light emitting function and is used as a medium for information transmission. .

이와 같이 엘이디(124)를 이용한 종래의 7세그먼트(100)는 도6 및 7에 나타낸 바와 같이, 상부면으로 문자 혹은 숫자를 형성한 다수의 중공홀(112)이 천공 형성된 몸체(110)와, 다수개의 엘이디(124)를 본딩하여 구비하고, 상기의 엘이디(124)를 전기적으로 연결하는 단자(125)를 구비한 회로기판(120)을 결합하여 상기 중공홀(112)의 내부로 광발산이 이루어지도록 에폭시수지(119)를 충진하여 구성된다.As described above, the conventional seven segment 100 using the LED 124 has a body 110 formed with a plurality of hollow holes 112 formed with letters or numbers on the upper surface thereof, as shown in FIGS. 6 and 7, A plurality of LEDs 124 are provided and bonded, and a circuit board 120 having a terminal 125 for electrically connecting the LEDs 124 is coupled to thereby emit light into the hollow hole 112. It is configured by filling the epoxy resin 119 to be made.

상기와 같은 종래의 7세그먼트(100)는 엘이디(124)로부터 발광되는 빛이 몸 체(110)의 상부면까지 도달하여 중공홀(112)의 외부로 발산될 때 균일하게 발산되도록 하기 위하여 중공홀(112)의 깊이를 엘이디(124)로부터 최소한의 적정 거리를 유지하여야 했다.The conventional seven-segment 100 as described above is a hollow hole so that the light emitted from the LED 124 reaches the upper surface of the body 110 to be evenly emitted when it is emitted to the outside of the hollow hole 112 Depth of (112) had to be kept to a minimum appropriate distance from LED (124).

이와 같이 균일한 발광을 위해 최소한의 적정 거리를 유지하여 구성되는 7세그먼트(100)는 두께(t2)가 5mm 정도로 두껍게 제작되어 두께가 얇은 전자제품이나 가전제품에는 사용할 수 없는 결점이 있었다.As described above, the seven segments 100 configured to maintain a minimum appropriate distance for uniform light emission have a thickness (t 2 ) of about 5 mm, so that they cannot be used in thin electronics or home appliances.

따라서, 상기와 같은 결점을 적게 하기 위하여 7세그먼트(100)의 두께를 얇게 형성할 경우에는 엘이디(124)로부터 발광되는 빛이 몸체(110)의 상부면까지의 거리가 짧아 중공홀(112)의 외부로 발산될 때 엘이디(124)의 중심부분은 밝고 주변은 상대적으로 어두운 상태로 발산하는 불균일한 발산으로 발산효율이 반감되는 결점이 있었다.Therefore, when the thickness of the seven segments 100 is formed in order to reduce the drawbacks as described above, the light emitted from the LED 124 is shorter to the upper surface of the body 110 so that the hollow hole 112 may be The central part of the LED 124 when it is emitted to the outside has a defect that the divergence efficiency is halved by a non-uniform divergence that radiates in a relatively dark state around the bright.

따라서, 본 발명은 상기와 같은 종래의 결점을 해결하고자 한 것으로, 7세그먼트를 구성하는 몸체에 형성된 각각의 중공홀 내부 일측으로 공간부를 형성하여 엘이디를 설치함으로서, 상기 공간부에 설치된 엘이디에서 발광되는 빛이 중공홀을 통하여 간접발산되어 방사되면서 외부로 발산되는 빛이 균일하게 발산되도록 함으로써 7세그멘트를 형성하는 몸체의 두께를 얇게 형성하여도 균일한 밝기로 발산되도록 하여 발산효율을 증대함은 물론 제품의 슬림화로 인해 설치 장소에 제약이 없 는 간접 조명방식을 이용한 초박형 7세그먼트의 구조를 제공하고자 함이다.Accordingly, the present invention is to solve the above-mentioned drawbacks, by forming a space portion on one side of each hollow hole formed in the body constituting the seven segments by installing the LED, which is emitted from the LED installed in the space portion As light is indirectly diverged through the hollow hole and radiated outwardly, the light emitted to the outside is uniformly radiated, so that even if a thin thickness of the body forming the seven segments is formed, the light is emitted with uniform brightness to increase the divergence efficiency. It is intended to provide a structure of ultra-slim 7-segment using indirect lighting method that does not have a limitation on the installation place due to the slimmer.

도1은 본 발명의 7세그먼트의 평면도, 도2는 도1의 A-A선 단면도를 나타낸 것으로,1 is a plan view of the seven segments of the present invention, Figure 2 is a cross-sectional view taken along the line A-A of Figure 1,
