도광판을 이용한 엘이디전등{LED-LAMP OF USING LIGHT-GUIDING PLATE}LED lamp using light guide plate {LED-LAMP OF USING LIGHT-GUIDING PLATE}

본 발명은 엘이디 전등에 관한 것으로, 더욱 상세하게는 도광판을 이용하여 엘이디 광의 확산을 보조하고 다양한 색상을 발생할 수 있는 엘이디 전등의 구조에 관한 것이다.The present invention relates to an LED lamp, and more particularly, to a structure of an LED lamp that can assist the diffusion of the LED light and generate a variety of colors using a light guide plate.

형광등은 일반 슈퍼나 전파사에서 손쉽게 구입할 수 있을 뿐더러 가격도 저렴하고 남녀노소 설치방법이 쉬워 사인업계뿐 아니라 전 조명업계에서 가장 오랫동안 그리고 많이 사용한 광원이다. 그러나 흑점 현상, 짧은 수명 등으로 잦은 교체와 색, 형태 등 디자인 표현에 한계가 있고 형광물질 사용으로 친환경을 지향하는 미래 조명시장의 흐름에 반하므로 점차 타 광원으로 대치되고 있는 추세이다.Fluorescent lamps can be easily purchased from general supermarkets or radio companies, are cheap, and easy to install for both sexes. However, there are limitations in design expression such as frequent replacement and color and shape due to sunspot phenomenon and short lifespan, and it is gradually being replaced by other light sources because it is contrary to the flow of future lighting market that aims to be eco-friendly by using fluorescent materials.

타 광원으로 가장 주목받고 있는 것은 엘이디(Light Emitting Diode)로써, 1962년 GaAsP 화합물 반도체를 이용한 적색 엘이디가 상품화된 것을 시작으로 GaP:N 계열의 녹색 엘이디와 함께 지금까지 정보통신기기를 비롯한 전자장치의 표시용 광원으로 이용되어 왔다. 90년대 중반 이후, GaN 청색 엘이디가 개발되면서 천연색 디스플레이가 가능하게 되었다. The most popular light source is LED (Light Emitting Diode). In 1962, red LED using GaAsP compound semiconductor was commercialized, and along with GaP: N-based green LED, It has been used as a light source for display. Since the mid-90s, GaN blue LEDs have been developed to enable natural color displays.

대표적인 이용분야로는, 핸드폰의 액정표시소자와 키 패드용 백 라이트를 들 수 있으며, 이외에도 옥외용 대형 전광판, 교통 신호등, 자동차 계기판 및 후미등, 항만, 공항, 고층 빌딩의 경고 및 유도등 과 같은 다양한 곳에 사용된다. 또한, 엘이디는 반도체의 빠른 처리 속도와 낮은 전력 소모 등의 장점과 함께, 환경 친화적이면서도 에너지 절약 효과가 높아서 차세대 국가 전략 품목으로 꼽히고 있다. 또한 엘이디의 장점은 기존의 광원에 비해 극소형이며, 소비전력이 적고, 수명이 기존의 전구에 비해 10배 이상이며, 빠른 반응속도로 기존의 광원에 비해 매우 우수한 특성을 나타낸다. 또한, 자외선과 같은 유해파의 방출이 없고, 수은 및 기타 방전용 가스를 사용하지 않는 환경 친화적인 광원이다.Typical applications include cell phone LCDs and backlights for keypads, as well as outdoor large billboards, traffic lights, car dashboards and taillights, ports, airports, skyscrapers, warnings and induction lamps. do. In addition, LED is considered as a next-generation national strategic item because of its advantages such as high processing speed and low power consumption of the semiconductor, and environmentally friendly and high energy saving effect. In addition, the advantages of the LED is very small compared to the conventional light source, the power consumption is low, the lifespan is more than 10 times than the conventional light bulb, and shows a very excellent characteristics compared to the conventional light source with a fast reaction speed. In addition, it is an environmentally friendly light source that does not emit harmful waves such as ultraviolet rays and does not use mercury and other discharge gases.

그러나, 엘이디는 에너지가 빛의 형태 뿐만 아니라, 열의 형태로도 방출되기 때문에 고온이 되기 쉬운 단점이 있다. 고온을 냉각시키기 위하여 엘이디등 외부에 통공을 구성하는 등이 일부 있으나 통공을 통하여 유입된 먼지나 기타 해충 등에 의해 엘이디등의 효율이 현저히 감소하게 된다. 또한 고온이 됨으로써 엘이디의 수명이 줄어들며, 고온이 된 엘이디의 열을 식히려는 연구는 지속적으로 수행되고 있다.However, LEDs are disadvantageous in that they tend to become hot because energy is emitted not only in the form of light but also in the form of heat. In order to cool the high temperature, there are some parts such as a through hole formed outside the LED, but the efficiency of the LED is significantly reduced due to dust or other pests introduced through the through hole. In addition, the lifetime of the LED is reduced by the high temperature, and researches to cool the LED of the high temperature are continuously conducted.

또한, 엘이디 광은 직진성이 있어 엘이디 바로 아래는 상당히 밝은 편이나 주변은 약간 어두운 편이다. 따라서 일반 전등으로 사용하기 위해서는 엘이디 광을 확산시킬 수 있는 별도의 장치가 필요하다.Also, the LED light is straight, so it's fairly bright just below the LED, but slightly darker around it. Therefore, in order to use as a general lamp, a separate device that can diffuse the LED light is required.

본 발명에 따라, 엘이디를 광원으로 사용하는 전등에 있어서, 엘이디에서 발생하는 열을 효과적으로 냉각시킬 있으며 엘이디 광의 직진성의 단점을 극복할 수 있는 다색 선택 가능한 엘이디 전등을 제공하고자 한다.According to the present invention, in a lamp using the LED as a light source, to provide a multi-color selectable LED lamp that can effectively cool the heat generated from the LED and overcome the disadvantages of the linearity of the LED light.

One column of the two columns may use the general white LED element 10, and the other column may use the LED element 10 of various colors, that is, blue or green. In addition, a remote controller 70 such as a wireless remote controller is provided outside the LED lamp 1 to control the blinking of the LED lamp 1. In the exemplary embodiment of the present invention, the LED elements 10 of two rows are used, but if the space limitation is overcome, the LED lamps 1 of various colors may be implemented by using the LED elements 10 of the multi-row and the multi-color.

회로기판(15) 내부는 전기적인 회로로 구성되며 외부는 일자형 바(BAR) 형태로 구성되어 엘이디전등(1)의 길이와 대응되게 구성된다. 회로기판(15)에는 교류전류를 엘이디용 직류전류로 바꾸어 주기 위한 컨버터(미도시) 및 원격조정이 가능하도록 회로소자(미도시)가 내장되어 있다. 또한 회로기판(15)은 도 1에서 보이는 전원핀(43)에 전기적으로 연결되어 있다.The inside of the circuit board 15 is composed of an electrical circuit, and the outside is formed in the form of a straight bar (BAR) to correspond to the length of the LED lamp (1). The circuit board 15 includes a converter (not shown) for converting an AC current into a DC current for an LED and a circuit element (not shown) to enable remote control. In addition, the circuit board 15 is electrically connected to the power pin 43 shown in FIG.

엘이디소자(10)가 실장된 회로기판(15)의 반대면은 방열커버(20)와 열전도가 우수한 구리스(미도시) 등으로 밀착되어 엘이디소자(10)에서 발생하는 열을 방열커버(20) 및 방열핀(23)을 통해 외부로 방출하도록 구성된다. 회로기판(15)을 ㄷ자 형상으로 구성한 것은 그 내측면에 실장된 엘이디소자(10)에서 방출되는 빛을 도광판(60)으로 대부분 보내기 위함이다.The opposite surface of the circuit board 15 on which the LED element 10 is mounted is in close contact with the heat dissipation cover 20 and a grease (not shown) having excellent thermal conductivity, thereby dissipating heat generated from the LED element 10. And it is configured to discharge to the outside through the heat radiation fin (23). The c-shaped circuit board 15 is configured to send most of the light emitted from the LED element 10 mounted on the inner surface to the light guide plate 60.

도광판(60)은 빛을 전체 면에 균일하게 전달하는 역할을 하는 플라스틱 성형 렌즈의 하나로, 일반적인 사용분야는 엘시디 패널에 주로 사용된다. 본 발명에서는 도광판(60)을 사용하여 엘이디 광을 고르게 확산시킬 수 있도록 하였다. 도광판(60) 상부 표면에는 도광판(60)에서 방출되는 빛을 반사시키기 위한 반사판(65)이 부착되어 있고 도광판(60)은 회로기판(15)과 결합된다. 반사판(65)은 플라스틱 재질로 구성될 수 있으며 일반적인 반사시트(미도시)가 부착되거나 반사물질(미도시)이 도포되어 사용된다. 본 발명에서는 굴곡이 있는 면에 반사물질이 도포된 반 사판(65)을 사용하여 구성하였다. 이에 따라 엘이디소자(10)에서 방출되는 광은 도광판(60)을 통해서 유도되며, 도광판(60)으로부터 누출되는 일부의 광은 상부의 반사판(65)을 통해서 반사되어 하측으로 진행한다. 하측으로 진행된 빛은 확산커버(30)를 통해 외부로 방출되며 확산커버(30)는 엘이디 광의 확산을 배가하는 역할을 하게 된다.The light guide plate 60 is one of plastic molded lenses that uniformly transmit light to the entire surface, and a general field of use is mainly used for LCD panels. In the present invention, the light guide plate 60 is used to evenly spread the LED light. The upper surface of the light guide plate 60 is attached with a reflector plate 65 for reflecting light emitted from the light guide plate 60 and the light guide plate 60 is coupled to the circuit board 15. The reflector plate 65 may be made of a plastic material, and a general reflective sheet (not shown) is attached or a reflective material (not shown) is applied. In the present invention was configured using a reflecting plate 65 coated with a reflective material on the curved surface. Accordingly, the light emitted from the LED device 10 is guided through the light guide plate 60, and part of the light leaked from the light guide plate 60 is reflected through the upper reflector 65 and proceeds downward. The light propagated downward is emitted to the outside through the diffusion cover 30 and the diffusion cover 30 serves to double the diffusion of the LED light.

본 발명에 따라, 엘이디소자의 발열 단점을 극복하고 직진성의 단점을 극복한 다색 선택 가능한 도광판을 이용한 엘이디전등을 제공할 수 있다.According to the present invention, it is possible to provide an LED lamp using a multi-color selectable light guide plate which overcomes the disadvantages of heat generation of the LED element and overcomes the disadvantages of straightness.
