And light is emitted through the circuit board 5 to illuminate the surroundings.

그러나, 이와 같은 기존의 LED형광등은 LED(7) 빛을 직접조명하기 때문에, LED(7)의 스폿(SPOT)이 보이는 문제가 있고, 눈이 부시며, 직접 눈으로 볼 때에 피로감이 발생한다는 문제가 있다. 이 때문에, 조명에 민감한 어린아이 및 병원의 환자들에게 사용하기에는 무리가 있다.However, since such conventional LED fluorescent lamps directly illuminate the LED 7 light, there is a problem that the spot of the LED 7 is visible, is dazzled, and a feeling of fatigue occurs when viewed directly by the eye. There is. Because of this, it is not suitable for use in light-sensitive children and patients in hospitals.

본 발명의 목적은 이와 같은 문제점을 해결하기 위한 것으로, LED 빛을 간접조명하여 눈부심 현상을 제거하고 눈의 피로감을 없애도록 하기 위한 간접조명 LED형광등을 제공하는데 있다.An object of the present invention is to solve such a problem, to provide an indirect illumination LED fluorescent lamp to indirectly illuminate the LED light to remove the glare phenomenon and eliminate eye fatigue.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 간접조명 LED형광등을 나타낸 사시도, 도 3은 본 발명의 간접조명 LED형광등을 나타낸 분리 사시도, 도 4는 도 2의 Ⅰ-Ⅰ선 단면도, 도 5는 본 발명의 간접조명 LED형광등의 사용상태도, 도 6은 본 발명의 변형예를 나타낸 도면이다.2 is a perspective view showing an indirect illumination LED fluorescent lamp of the present invention, Figure 3 is an exploded perspective view showing an indirect illumination LED fluorescent lamp of the present invention, Figure 4 is a cross-sectional view taken along line I-I of Figure 2, Figure 5 is an indirect illumination LED of the present invention 6 is a view showing a modified example of the present invention.

도면에 나타낸 바와 같이, 본 발명의 간접조명 LED형광등은 형광등 소켓(미도시)에 끼움 설치됨으로써 전기적으로 접속하여 빛을 조사하며, 개구된 양단을 가로질러 절개부(111a)를 형성한 U자형의 커버(111)와, 커버(111)의 절개부(111a)에 상부만이 노출되게 끼움 설치되어 커버(111)와의 단면을 원형으로 형성하는 금속체(130)를 구비한다.As shown in the figure, the indirect illumination LED fluorescent lamp of the present invention is fitted in a fluorescent lamp socket (not shown) to be electrically connected and irradiated with light, and U-shaped with a cutout 111a formed across both open ends. It is provided with a cover 111 and the metal body 130 is fitted so that only the upper portion is exposed to the cutout portion (111a) of the cover 111 to form a cross section with the cover 111 in a circular shape.

절개부(111a)는 커버(111)의 상부에 형성되며, 금속체(130)는 절개부(111a)가 형성하는 개구에 설치되어 커버(111)의 상부를 덮는다.The cutout 111a is formed at an upper portion of the cover 111, and the metal body 130 is installed at an opening formed by the cutout 111a to cover the upper portion of the cover 111.

즉, 금속체(130)는 절개부(111a)를 형성하는 커버(111)의 단부들에 끼워질 수 있는 끼움홈(131)을 좌우측에 요입 형성하여 커버(111)의 단부들에 슬라이드하게 끼워짐으로써 절개부(111a)를 덮어 커버(111)와 함께 원통형의 봉(棒)을 형성한다.That is, the metal body 130 slides into the end portions of the cover 111 by forming recesses on the left and right sides of the fitting groove 131 that can be fitted to the ends of the cover 111 forming the cutout 111a. By covering, the cover 111 is covered to form a cylindrical rod together with the cover 111.

즉, 금속체(130)는 외부로 노출되는 상부를 원호상으로 형성하여 커버(111)와 결합된 단면이 형광등과 같은 원형을 이루도록 하며, 이때 커버(111)는 단부들을 내측으로 ㄴ자형으로 절곡하여 금속체(130)가 절개부(111a)에 용이하게 끼워질 수 있도록 한다.That is, the metal body 130 forms an upper portion exposed to the outside in an arc shape so that the cross section combined with the cover 111 forms a circular shape such as a fluorescent lamp. In this case, the cover 111 is bent into the letter B shape inwards. The metal body 130 can be easily fitted to the cutout 111a.

금속체(130)는 전열성이 우수한 알루미늄과 같은 금속으로 이루어지기 때문에 LED(141) 발광시 발생되는 열을 노출면인 상부면을 통해서 효과적으로 방열하여 LED(141)를 적정 온도로 유지시켜 줌으로서 LED(141)의 수명을 크게 연장시킨다.Since the metal body 130 is made of a metal such as aluminum having excellent heat conductivity, the heat generated when the LED 141 is emitted is effectively radiated through the upper surface, which is an exposed surface, thereby maintaining the LED 141 at an appropriate temperature. It greatly extends the life of the LED 141.

이때, 금속체(130)는 상부면에 일정 간격을 두고 홈을 파 다수의 방열핀(133)을 형성하여 방열 면적을 확대함으로써 방열 효율을 더 크게 높이고 있다.At this time, the metal body 130 increases the heat dissipation efficiency by increasing the heat dissipation area by forming a plurality of heat dissipation fins 133 through the groove at regular intervals on the upper surface.

이러한 금속체(130)에는 돌기(151)가 돌출 형성된다.Projections 151 are formed to protrude from the metal body 130.

돌기(151)는 커버(111)의 내부에 위치하는 금속체(130)의 하부로부터 돌출 형성되어 LED(141)를 배열한 인쇄회로기판(143)의 설치장소를 마련하여 지지함과 아울러 LED(141) 발광시 발생되는 열을 1차 방열하고 그 나머지 열은 금속체(130)가 2차 방열할 수 있게 전도한다.The protrusion 151 protrudes from the lower portion of the metal body 130 positioned inside the cover 111 to provide and support an installation place of the printed circuit board 143 in which the LEDs 141 are arranged. 141) The heat generated during light emission is primarily radiated, and the remaining heat is conducted to allow the metal body 130 to radiate secondary.

예컨대, 돌기(151)는 금속체(130)의 길이를 따라 돌조형으로 돌출 형성되어 바(bar) 형상의 인쇄회로기판(143)에 길이를 따라 일정 간격을 두고 배열된 LED(141)를 측면에 설치하여 LED(141)가 커버(111)의 측면 쪽으로 빛을 조사할 수 있도록 장소를 마련하며, 나아가 LED(141)가 빛을 조사하는 동안 발생되는 열을 1차 방열하고 그 나머지 열은 금속체(130)가 2차 방열할 수 있게 전도함으로써 LED(141)를 적정 온도로 더 유지시켜 주어 LED(141)의 수명을 더 크게 연장시킨다.For example, the protrusion 151 protrudes in the shape of a protrusion along the length of the metal body 130 to the side of the LED 141 arranged at regular intervals along the length of the bar-shaped printed circuit board 143. It is installed in the LED 141 to provide a place for irradiating the light toward the side of the cover 111, and further heat the heat generated while the LED 141 irradiates the light and the remaining heat is metal The body 130 conducts secondary heat dissipation to further maintain the LED 141 at an appropriate temperature, thereby extending the life of the LED 141 even more.

이와 같은 돌기(151)는 금속체(130)와 같은 재질로서 금속체(130)가 성형될 때에 같이 성형되어 형성됨이 좋다.The protrusion 151 may be formed of the same material as that of the metal body 130 when the metal body 130 is molded.

이에 의해 커버(111)의 측면 쪽으로 조사되는 LED(141) 빛은 반사 층(161,163)에 의해서 커버(111)의 하부 쪽으로 반사되어 간접조명을 이룬다.As a result, the LED 141 light emitted toward the side of the cover 111 is reflected toward the lower side of the cover 111 by the reflective layers 161 and 163 to form indirect illumination.

즉, 반사층(161,163)은 LED(141) 빛이 조사되는 커버(111)의 내측면 즉, 금속체(130)의 좌우측으로 부터 원주를 따라 커버(111)의 내측면에 설치되어, 커버(111)의 측면 쪽으로 조사되는 LED(141) 빛을 커버(111)의 하부를 통해서 형광등 아래에 놓이는 조사대상이나 조사공간으로 반사함으로써 간접조명을 이루도록 한다.That is, the reflective layers 161 and 163 are disposed on the inner surface of the cover 111 to which the LED 141 light is irradiated, that is, the inner surface of the cover 111 along the circumference from the left and right sides of the metal body 130, and the cover 111. By reflecting the LED (141) light irradiated toward the side of the cover through the lower portion of the cover 111 to the irradiation object or irradiation space placed under the fluorescent lamp to achieve indirect lighting.

반사층(161,163)은 반사지, 반사필름, 반사테이프 중 어느하나를 커버(111)의 내측면에 부착시킴으로써 형성될 수 있고, 이와 달리 반사도료를 도포함으로써 형성될 수 있다.The reflective layers 161 and 163 may be formed by attaching any one of a reflective paper, a reflective film, and a reflective tape to the inner surface of the cover 111, or may be formed by applying a reflective paint.

이때, 커버(111)는 LED(141) 빛이 투과하는 하부를 투명하게 형성하여 빛의 투과율을 높임으로써 빛의 효율을 더 높일 수 있다.In this case, the cover 111 may further increase the efficiency of light by forming the lower part through which the LED 141 light transmits transparently to increase the light transmittance.

이와 같은 간접조명은 도 5에 도시된 바와 같이 돌기(151)를 중앙에 형성하고 그 좌우측에 LED(141)를 설치하여 빛을 좌우 양방으로 조사하여 얻을 수 있고, 도 6에 도시된 바와 같이 돌기(151)를 어느 한쪽으로 치우치게 형성하고 그 치우친 반대방향으로 LED(141) 빛을 일방으로 조사하여 얻을 수 있다.Such indirect lighting can be obtained by forming projections 151 at the center as shown in FIG. 5 and installing LEDs 141 at the left and right sides thereof to irradiate the light to both the left and right sides, and as shown in FIG. 6. 151 is formed to be biased to one side, and can be obtained by irradiating LED 141 light in one direction in the opposite direction to the bias.

간접조명의 광원인 LED(141)는 형광등 소켓과 접속하는 단자(171a)를 갖고 금속체(130)와 커버(111)가 형성하는 개구된 양단에 설치되어 폐쇄하는 캡부재(171)로부터 전원을 공급받아 발광하여 빛을 조사한다.The LED 141, which is a light source of indirect illumination, has a terminal 171a for connecting to a fluorescent lamp socket and is installed at both open ends formed by the metal body 130 and the cover 111 to close the power supply from the cap member 171. It receives light and emits light.

즉, 캡부재(171)의 단자(171a)는 인쇄회로기판(143)과 전기적으로 연결되므로, LED(141)는 형광등 소켓으로부터의 전원을 캡부재(171)의 단자(171a)와 인쇄회 로기판(143)를 통해서 인가받아 발광하여 반사층(161,163)이 반사하여 간접조명을 이루는 빛을 조사한다.That is, since the terminal 171a of the cap member 171 is electrically connected to the printed circuit board 143, the LED 141 may supply power from the fluorescent lamp socket to the terminal 171a of the cap member 171 with the printed circuit. When the light is applied through the substrate 143 to emit light, the reflective layers 161 and 163 reflect the light to form indirect illumination.

이와 같은 본 발명은 LED 빛을 간접조명하기 때문에, LED 스폿이 보이는 문제를 해소하고, 눈부심 현상을 제거함과 아울러 직접 눈으로 볼 때에 그 피로감을 없앤다.Since the present invention indirectly illuminates the LED light, it eliminates the problem of seeing the LED spot, eliminates the glare phenomenon and eliminates the fatigue when viewed directly.

이 때문에, 조명에 민감한 어린아이나 병원의 환자들에게 사용하기데 무리가 없고, 간접조명 전용 인테리어용으로 사용이 가능하다.Because of this, it is easy to use for the light-sensitive infants or patients in the hospital, and can be used for interior lighting only.

또한, 본 발명은 가로등이나 방범등, 터널등에 적용되면, 눈부심 현상의 제거로 운전자의 피로감을 제거하여 이로 인해 사고를 크게 감소시킬 것이다.In addition, when the present invention is applied to street lights, security lights, tunnels, etc., by eliminating the glare phenomenon will eliminate the fatigue of the driver, thereby greatly reducing the accident.

또한, 본 발명은 LED 발광시 발생되는 열이 효과적으로 방열함으로써 LED 수명을 크게 연장시킨다.In addition, the present invention extends the LED life significantly by effectively dissipating heat generated when the LED emits light.

상술한 바와 같이 본 발명에 의하면, LED 빛을 간접조명함으로써 눈부심 현상을 제거하고 눈의 피로감을 없앨 수 있는 LED형광등이 제공된다.As described above, according to the present invention, there is provided an LED fluorescent lamp that can remove glare and eliminate eye fatigue by indirectly illuminating the LED light.
