도 7은 본 고안의 LED 형광등의 사용상태도이다.7 is a state diagram used in the LED fluorescent lamp of the present invention.

도면에 나타낸 바와 같이, 본 고안의 LED 형광등은 형광등 소켓(미도시)에 끼움 설치됨으로써 전기적으로 접속하여 빛을 조사하도록 한 조명수단(110)을 구비한다.As shown in the figure, the LED fluorescent lamp of the present invention is provided with a lighting means 110 to be electrically connected by irradiating light by being fitted in a fluorescent lamp socket (not shown).

조명수단(110)은 양단이 개구된 원통형상의 커버(111)와, 형광등 소켓과 접속하는 단자(113a)를 갖고 커버(111)의 개구된 양단에 설치되어 커버(111)를 폐쇄 하는 캡부재(113)와, 커버(111)의 내부에 설치되어 캡부재(113)의 단자(113a)와 전기적으로 연결되는 바(bar)형상의 회로기판(115)에 길이를 따라 일정 간격을 두고 배열되는 LED(117)로 이루어진다.The luminaire 110 has a cylindrical cover 111 having both ends opened, and a terminal 113a connected to the fluorescent lamp socket, and installed at both ends of the cover 111 to close the cover 111 ( 113 and an LED installed in the cover 111 and arranged at a predetermined interval along a length on a bar-shaped circuit board 115 electrically connected to the terminal 113a of the cap member 113. It consists of 117.

이러한 조명수단(110)은 LED(117)가 형광등 소켓으로부터의 전원을 캡부재(113)의 단자(113a)와 회로기판(115)를 통해서 인가받아 발광함으로써 빛을 조사하여 주위를 환하게 한다.The lighting means 110 is the LED 117 is applied through the terminal 113a of the cap member 113 and the circuit board 115 by the power from the fluorescent lamp socket to emit light to illuminate the surroundings.

이 구조에서, 커버(111)에는 절개부(121)가 형성되고, 절개부(121)에는 금속체(130)가 설치된다. 절개부(121)는 커버(111)의 길이를 따라 형성되어 캡부재(113)에 의해 폐쇄되는 커버(111)를 개구하며, 금속체(130)가 LED(117)의 빛을 차단하지 않도록 커버(111)의 상부에 형성된다.In this structure, a cutout 121 is formed in the cover 111, and a metal body 130 is installed in the cutout 121. The cutout 121 is formed along the length of the cover 111 to open the cover 111 closed by the cap member 113, so that the metal body 130 does not block the light of the LED 117. It is formed on the top of 111.

금속체(130)는 절개부(121)가 형성하는 개구에 설치되어 커버(111)를 폐쇄하며, 절개부(121)와 대면하는 커버(111)의 단부들에 끼워질 수 있는 끼움홈(131)을 좌우측에 요입 형성하여 커버(111)의 단부들에 슬라이드하게 끼워짐으로써 절개부(121)를 덮어 커버(111)를 폐쇄한다. 이때, 커버(111)는 단부들을 내측으로 ㄴ자형으로 절곡하여 금속체(130)가 절개부(121)에 용이하게 끼워질 수 있도록 한다.The metal body 130 is installed in an opening formed by the cutout 121 to close the cover 111 and may be fitted into the end portions of the cover 111 facing the cutout 121. ) Is formed in the left and right sides by slidingly fitted to the ends of the cover 111 to cover the cut portion 121 to close the cover 111. In this case, the cover 111 bends the ends inward to the letter B so that the metal body 130 can be easily fitted to the cutout 121.

이와 같이 설치되는 금속체(130)는 외부로 노출되는 면을 원호상으로 형성하여 커버(111)와 결합되는 전체 단면이 형광등과 같이 원형을 이루도록 하고, 내부에 위치하는 면은 평면으로 형성하여 LED(117)를 배열한 회로기판(115)의 설치장소를 마련하여 견고히 지지한다.The metal body 130 installed as described above is formed in a circular arc shape on the surface exposed to the outside so that the entire cross section combined with the cover 111 forms a circle like a fluorescent lamp, and the surface located inside is formed in a flat LED shape. An installation place of the circuit board 115 having the arrangement of 117 is provided and firmly supported.

이러한 금속체(130)는 전열성이 큰 알루미늄과 같은 금속으로 이루어지고, LED(117) 발광시 발생되는 열을 외부로 노출되는 면을 통해 방열함으로써 LED(117)를 적정 온도로 유지시켜 주어 LED(117)의 수명을 크게 연장시킨다.The metal body 130 is made of a metal such as aluminum having high heat conductivity, and heats heat generated when the LED 117 emits through a surface exposed to the outside to maintain the LED 117 at an appropriate temperature. Significantly extends the life of 117.

또한, 금속체(130)는 외부로 노출되는 면에 일정 간격을 두고 홈을 파 다수의 방열핀(133)을 형성하여 방열 면적을 확대함으로써 방열 효율을 크게 높이고 있다.In addition, the metal body 130 increases the heat dissipation efficiency by forming a plurality of heat dissipation fins 133 having grooves at predetermined intervals on the surface exposed to the outside to enlarge the heat dissipation area.

이처럼 LED(117) 발광시 발생되는 열을 방열하여 LED(117)를 적정 온도로 유지시켜 주는 금속체(130)에는 돌기(135)가 형성된다. 돌기(135)는 LED(117)를 감싸듯이 금속체(130)의 좌우측으로부터 커버(111)의 원주를 따라 연장 형성되며, 그 표면은 도 4에 도시된 바와 같이 곡선으로 형성되거나, 도 5에 도시된 바와 같이 각지게 형성되거나, 도시하지는 않았지만 곡선과 각을 혼합해서 형성되거나, 요철 모양 등으로 형성되는데, 이와 같은 표면의 모양은 하기와 같은 반사를 고려해서 다양하게 형성된다.As described above, the projection 135 is formed on the metal body 130 that maintains the LED 117 at an appropriate temperature by dissipating heat generated when the LED 117 emits light. The protrusion 135 extends along the circumference of the cover 111 from the left and right sides of the metal body 130 so as to surround the LED 117, and the surface thereof is formed in a curve as shown in FIG. 4, or in FIG. 5. Although not illustrated as shown, or formed by mixing a curve and an angle, but not shown, or is formed in a concave-convex shape or the like, the shape of such a surface is formed in various ways in consideration of the following reflection.

즉 도 6에 도시된 바와 같이, 돌기(135)는 금속체(130)의 좌우측으로 조사되는 LED(117) 빛을 반사하여 커버(111)의 아래를 향하게 함으로서 빛의 효율을 크게 증대시킨다. 또한, 돌기(135)는 금속체(130)의 방열 면적을 더 확대하여 방열 효율을 크게 높이도록 한다.That is, as shown in Figure 6, the projection 135 reflects the LED 117 light irradiated to the left and right sides of the metal body 130 to direct the bottom of the cover 111 to greatly increase the efficiency of the light. In addition, the protrusion 135 further increases the heat dissipation area of the metal body 130 to greatly increase the heat dissipation efficiency.

한편, 금속체(130)의 좌우측으로 조사되는 LED(117) 빛을 더 효과적으로 반사하기 위해, 도 7에 도시된 바와 같이 돌기(135)를 포함하는 금속체(130)의 표면에는 제1반사층(141)이 형성된다.On the other hand, in order to more effectively reflect the LED 117 light emitted to the left and right sides of the metal body 130, as shown in Figure 7, the surface of the metal body 130 including the projection 135, the first reflection layer ( 141 is formed.

제1반사층(141)은 반사물질을 도포하여 형성되거나, 반사지 또는 반사필름 또는 반사테이프 등을 붙임으로써 형성되어, 금속체(130)의 좌우측으로 조사되는 LED(117) 빛을 더 효과적으로 반사함으로써 빛의 효율을 크게 증대시키도록 한다.The first reflection layer 141 is formed by applying a reflective material, or is formed by applying a reflective paper or a reflective film or a reflective tape, thereby more effectively reflecting the LED 117 light emitted to the left and right sides of the metal body 130. It will greatly increase the efficiency of the.

나아가, 회로기판(115)의 표면에도 반사지 또는 반사필름 또는 반사테이프 등을 붙임으로써 제2반사층(151)을 형성하여 금속체(130)의 좌우측으로 조사되는 LED(117) 빛을 더 효과적으로 반사함으로써 빛의 효율을 더 크게 증대시키고 있다.Furthermore, the second reflective layer 151 is formed on the surface of the circuit board 115 by attaching a reflective paper or a reflective film or a reflective tape to more effectively reflect the light of the LED 117 irradiated to the left and right sides of the metal body 130. It is increasing the efficiency of light even more.

상술한 바와 같이 본 고안에 의하면, LED 발광시 발생되는 열을 효과적으로 방열함으로써 LED 수명을 크게 연장시키고, LED의 좌우측으로 조사되는 빛도 효과적으로 반사함으로써 빛의 효율을 크게 증대시키는 LED 형광등이 제공된다.As described above, according to the present invention, there is provided an LED fluorescent lamp which greatly extends the LED lifetime by effectively dissipating heat generated during LED emission, and greatly increases the efficiency of light by effectively reflecting the light irradiated to the left and right sides of the LED.
