엘이디 형광램프{FLUORESCENT LAMP USING LED}LED Fluorescent Lamp {FLUORESCENT LAMP USING LED}

본 발명은 엘이디 형광램프에서 발산되는 빛이 외부에서 뚜렷하고 깔끔하게 입체조명되도록 하는 엘이디 형광램프에 관한 것으로, 더욱 상세하게는 엘이디 형광램프 내측에 길게 배치된 엘이디 어레이로부터 발광되는 엘이디 빛이 원형 확산커버에서의 전방측 빛확산부위와 후방측 차단커버에서의 빛차단부위간의 경계부위에서 자연스럽고 깔끔하게 보일 수 있도록 하는 개량 엘이디(LED) 형광램프에 관한 것이다. The present invention relates to an LED fluorescent lamp that allows the light emitted from the LED fluorescent lamp to be clearly and neatly stereoscopically illuminated from the outside. More specifically, the LED light emitted from the LED array long disposed inside the LED fluorescent lamp has a circular diffusion cover. The present invention relates to an improved LED fluorescent lamp which can be seen naturally and neatly at the boundary between the light diffusing portion in the front side and the light blocking portion in the rear blocking cover.

실내외를 밝혀주는 조명장치는 광원의 빛을 반사?굴절?투과시켜 광원을 고정하거나 보호하는 조명기구를 구비하고 있는바, 이 조명기구는 다양한 광원의 빛을 반사?굴절?투과시켜 광원을 고정하거나 보호하는 기구이다. 상기 조명장치의 광원으로는 실내에서 사용되는 백열등 및 형광등이 있으며, 또 공원 등이나 가로등과 같이 실외에서 사용되는 할로겐램프 등이 있다.The lighting device that illuminates the interior and exterior is provided with a luminaire that reflects, refracts, and transmits the light of the light source to fix or protect the light source. It is a mechanism to protect. Light sources of the lighting apparatus include incandescent and fluorescent lamps used indoors, and halogen lamps used outdoors such as parks and street lights.

상기 조명기구의 광원으로 사용되는 부품으로써 최근 엘이디(LED; Lighting Emitting Diode)가 널리 사용되고 있는 추세에 있는데, 엘이디는 빛을 내는 반도체로서, 낮은 전력소비(백열등의 1/6), 긴 수명(백열등의 8배) 및 친환경적 특성(수은 등 유해물질 미함유)으로 각종 LCD의 광원, 실내등, 가로등, 조명등 및 자동차 등 다양한 분야에서 각 용도에 맞게 응용되고 있다.As a light source of the lighting fixture, LED (Light Emitting Diode) has recently been widely used, LED is a light emitting semiconductor, low power consumption (1/6 of incandescent lamp), long life (incandescent lamp) 8 times) and eco-friendly properties (without harmful substances such as mercury), it is applied for various purposes in various fields such as light source, indoor light, street light, lighting and automobile of various LCDs.

이와 같은 엘이디 조명장치는 엘이디 소자나 엘이디 모듈을 이용하여 조명을 하는 조명장치인 데, 기존의 조명기구인 형광등, 백열등에 비하여 수명이 길고 소요전력이 낮은 이점이 있어 실내조명등은 물론 가로등 등으로서 다양하게 활용되고 있다. 특히, 현재 엘이디 조명장치는 백열등 또는 형광등이 사용되는 기존 조명장치를 대체하고 있다.The LED lighting device is a lighting device that uses the LED element or the LED module. The LED lighting device has a long life and low power consumption compared to the fluorescent lamps and incandescent lamps. It is utilized. In particular, the current LED lighting device is replacing the existing lighting device used incandescent or fluorescent lamps.

그런데, 엘이디 조명장치는 빛의 발산시 발생되는 열에 의해 효율이 많이 좌우되어 열의 방출을 위한 방열구조를 구비하여 중량이 상대적으로 높으며 구조적으로 복잡하다. 또한, 상기 엘이디는 빛의 세기가 매우 강하며 직진성이 있어 사용자의 눈을 피로하게 할 뿐만 아니라 빛의 확산 특성이 낮은 점도 있었다.By the way, the LED lighting device is highly dependent on the heat generated when the light is emitted and has a heat dissipation structure for dissipation of heat, which is relatively high in weight and structurally complicated. In addition, the LED has a very strong light intensity and straightness, which not only makes the user's eyes tired but also has a low light diffusion characteristic.

따라서, 엘이디의 빛 확산을 기하기 위해 확산커버를 이용하여 엘이디 형광램프로서의 최대한 조명역할을 수행하게 되지만, 상기 확산커버내의 엘이디 어레이 주변, 즉 양 측면으로 조명이 얼룩지는 현상이 발생되고 있음으로 외부에서의 입체조명으로 발휘하는 데에는 그 한계가 있었다. Therefore, in order to diffuse the light of the LED, the diffusion cover is used to perform the maximum lighting role as the LED fluorescent lamp, but the illumination is spotted around the LED array in the diffusion cover, that is, both sides. There was a limit to the three-dimensional illumination of Esau.

이에 본 출원인은 상기와 같이 내장된 엘이디 어레이의 주변으로 빛이 투과되는 부위와 차단되는 부위간의 경계부위에서 발생되는 얼룩지는 조명을 해소하기 위해 빛의 샤프니스(SHARPNESS)와 라우드니스(LOUDNESS)를 고려하여 확산커버에서의 엘이디 빛 확산을 자연스럽게 연출될 수 있도록 다양한 수단을 강구하여 엘이디 형광램프에 적용하게 되었다. In this regard, the present applicant diffuses in consideration of SHARPNESS and LOUDNESS of light in order to solve the smudged light generated at the boundary between the light transmitting part and the blocking part around the embedded LED array as described above. Various measures were taken to apply LED light in the cover to the LED fluorescent lamp.

본 발명은 상기와 같은 제반 사정을 감안하여 원통형 커버에서의 빛 흡수 및 방열이 개선된 발명으로, 원통형 커버내에서 길게 배치된 엘이디 어레이로부터 발광되는 각 엘이디 빛들이 원형 확산커버에서의 전면 빛확산과 배면 차단커버에서의 바닥 양측면 빛차단을 자연스럽게 수행하게 됨으로 종래 특성보다 외부에서 엘이디 빛들이 뚜렷하고 깔끔하게 입체조명될 수 있는 엘이디(LED) 형광램프를 제공하고자 함에 그 목적이 있다. The present invention is an improved light absorption and heat dissipation in the cylindrical cover in view of the above circumstances, each LED light emitted from the LED array long disposed in the cylindrical cover and the front light diffusion in the circular diffusion cover and The purpose of the present invention is to provide LED fluorescent lamps that allow LED lights to be clearly and neatly stereoscopically illuminated from the outside by naturally blocking light on both sides of the bottom of the rear blocking cover.

상기 목적을 달성하기 위한 본 발명은, 길게 배치된 엘이디 어레이기판이 내장된 엘이디 형광램프에 있어서, 상기 엘이디 어레이기판을 감싸는 원통형 커버는 엘이디 빛을 광각으로 부드럽게 외부로 퍼지게 하는 원통형의 75 %를 차지하는 전방측 확산커버와 상기 엘이디 빛이 바닥 좌우측에서 얼룩지는 현상을 없애줄 수 있도록 빛의 투과를 완전히 차단하는 원통형의 25 %를 차지하되, 광원으로부터 발산되는 빛을 완전히 흡수하거나, 흡수 및 방열하는 후방측 차단커버를 구성하여, 상기 엘이디 어레이기판이 상기 후방측 차단커버 내측에 설치된 것을 특징으로 한다. The present invention for achieving the above object, in the LED fluorescent lamp with a long array of LED array substrate, the cylindrical cover surrounding the LED array substrate occupies 75% of the cylindrical to spread the LED light to the outside smoothly at a wide angle The front diffusion cover and the LED light occupy 25% of the cylindrical shape to completely block the transmission of light so as to eliminate the phenomenon of staining on the left and right sides, and the rear side completely absorbs, absorbs and radiates the light emitted from the light source. By constructing the blocking cover, the LED array substrate is characterized in that installed inside the rear blocking cover.

이상 설명한 바와 같이 본 발명에 의하면, 종래의 확산커버와 달리 엘이디 어레이상의 후방측 바닥커버를 이용하여 원통형 커버의 전방측 좌우 측면으로 얼룩지어지는 현상을 제거하여 외관상 미려한 조명상태를 유지해주는 효과가 있다. As described above, according to the present invention, unlike the conventional diffusion cover, by using the rear bottom cover on the LED array, the phenomenon of staining on the front left and right sides of the cylindrical cover is removed, thereby maintaining a beautiful lighting state in appearance. .

또, 본 발명은 기존 형광등이 가지는 조명기구의 특성을 최대한 자연스럽고 근접하게 구현함으로써 종래의 형광등과 같이 조명사용이 가능하여 사용자의 사용이 보다 편리한 이점이 있다. In addition, the present invention has the advantage that the user can be more convenient to use the lighting as a conventional fluorescent lamp by implementing the characteristics of the existing lighting fixtures as natural and close as possible.

도 2 는 본 발명의 엘이디 형광램프를 설명하기 위한 사용상태도이다. 1 is a perspective view showing an LED fluorescent lamp according to an embodiment of the present invention,
Figure 2 is a state diagram used for explaining the LED fluorescent lamp of the present invention.

이하, 본 발명의 바람직한 실시예를 예시도면에 의거하여 상세히 설명한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 은 본 발명의 실시예에 관한 엘이디 형광램프를 도시해 놓은 사시도이고, 본 발명은 엘이디 형광램프를 외부에서 볼 때 엘이디 형광램프에서 발산되는 빛이 뚜렷하고 깔끔하게 보이도록 한 것이다. 1 is a perspective view showing an LED fluorescent lamp according to an embodiment of the present invention, the present invention is to make the light emitted from the LED fluorescent lamp to look clearly and neat when viewed from the outside.

본 발명의 엘이디 형광램프는 길게 배치된 엘이디 어레이기판(40)이 내장되고 있는 바, 즉 상기 엘이디 어레이기판(40)을 원통형 커버(10)가 감싸고 있음으로 엘이디 어레이의 주변으로 얼룩지는 조명을 해소하기 위해 본 발명의 원통형 커버(10)는 빛의 사프니스(SHARPNESS) 효과와 라우드니스(LOUDNESS) 효과를 고려하여 확산커버에서의 엘이디 빛 확산을 자연스럽게 퍼지도록 연출될 수 있다. The LED fluorescent lamp of the present invention has a long array of LED array substrate 40 is built-in, that is, the cylindrical cover 10 is wrapped around the LED array substrate 40 to eliminate the illumination stained around the LED array surroundings To this end, the cylindrical cover 10 of the present invention may be produced to naturally spread the LED light diffusion in the diffusion cover in consideration of the SHARPNESS effect and the LOUDNESS effect of light.

상기 확산커버에서 빛의 사프니스(SHARPNESS)는 서서히 어두워지게 함으로 전면의 전체로 부드럽게 변화를 주는 효과이고, 빛의 라운드니스(LOUDNESS)는 밝은 것을 밝게 하고 어두운 것을 어둡게 해주는 효과인 것이다. 따라서, 상기 원통형 커버(10)는 빛이 투과되어 확산되는 전방측 확산커버(20)와 빛을 완전히 차단하는 후방측 차단커버(30)가 결합되어 원형태의 커버로 사용되고 있다. The SHARPNESS of the light in the diffusion cover is to gradually darken the effect of smoothly changing the entire front, LOUDNESS of light is to brighten the light and darken the effect. Thus, the cylindrical cover 10 is used as a circular cover by combining the front side diffusion cover 20 through which light is transmitted and the rear side blocking cover 30 that completely blocks the light.

엘이디 광원에서 발생되는 빛을 광각으로 확산시켜 주는 확산커버(20)는 엘이디 빛을 부드럽게 외부로 퍼지게 하는 부분으로, 원형중 75 %를 차지하는 커버이고, 그 재질은 투명한 재질이나 불투명재질을 사용하여 광원으로부터 발산되는 빛에 부드러운 변화를 주어 외부로 퍼지도록 하고 있다.  Diffusion cover 20 that diffuses the light emitted from the LED light source at a wide angle is a part that gently spreads the LED light to the outside, occupies 75% of the circle, the material is a light source using a transparent material or an opaque material A soft change is made to the light emitted from the outside to spread out.

후방측 차단커버(30)는 엘이디 모듈에서 발생되는 빛이 전방측 확산커버(20)에 의해 반사되어 후방측 바닥부위, 특히 전방측 확산커버(20)와 후방측 차단커버(30)가 만나는 경계부위에서 얼룩지는 현상을 없애주기 위한 것으로, 원형중 대략 25 %를 차지하는 커버이다. 그러므로, 후방측 차단커버(30)는 광원으로부터 발산되는 빛을 흡수하거나, 흡수와 함께 방열할 수 있도록 된 것으로, 경우에 따라서는 내부 코팅을 하거나 흑색 천연소재(PLA)를 사용여 빛을 흡수하거나 빛을 차단하도록 할 수도 있다. The rear blocking cover 30 is a boundary portion where the light generated from the LED module is reflected by the front diffusion cover 20 so that the rear bottom portion, in particular, the front diffusion cover 20 and the rear blocking cover 30 meet. It is a cover that takes up about 25% of the original shape to eliminate the staining from above. Therefore, the rear blocking cover 30 is to absorb the light emitted from the light source, or to be radiated with the absorption, in some cases the internal coating or using a black natural material (PLA) to absorb the light You can also block the light.

본 발명의 원통형 커버(10)에서는 상기 엘이디 어레이기판(40)이 후방측 차단커버(30)의 내측에 설치되어 완성형의 엘이디 형광램프로 사용할 수 있게 된다. In the cylindrical cover 10 of the present invention, the LED array substrate 40 is installed inside the rear side blocking cover 30 to be used as a completed LED fluorescent lamp.

이상과 같이 구성되는 본 발명은 종래의 확산커버와 달리 엘이디 어레이상의 후방측 바닥커버를 이용하여 원통형 커버에서 빛이 발산되는 부위와 차단되는 부위간의 경계부위에서의 좌우 측면으로 얼룩지어지는 현상을 제거하여 외관상 미려한 조명상태를 유지해줄 수 있다. The present invention configured as described above removes the phenomenon of staining on the left and right sides at the boundary between the light emitting portion and the blocked portion in the cylindrical cover by using the rear bottom cover on the LED array unlike the conventional diffusion cover. It can maintain a beautiful lighting condition.

도 2 는 본 발명의 엘이디 형광램프를 설명하기 위한 사용상태도이다. Figure 2 is a state diagram used for explaining the LED fluorescent lamp of the present invention.

본 발명의 엘이디 형광램프에서 원통형 커버(10)는 빛을 투과시켜 확산시키는 전방측 확산커버(20)와 빛을 완전히 차단하는 후방측 차단커버(30)를 원통형으로 체결한 것으로, 상기 원통형 커버(10)에 내장된 상기 엘이디 어레이기판(40)이 후방측 차단커버(30)에 설치되어 완성형의 엘이디 형광램프로서 사용할 수 있게 된다. In the LED fluorescent lamp of the present invention, the cylindrical cover 10 is to fasten the front side diffusion cover 20 for transmitting and diffusing light and the rear side blocking cover 30 for completely blocking the light, the cylindrical cover ( The LED array substrate 40 embedded in the 10) is installed in the rear blocking cover 30 to be used as a completed LED fluorescent lamp.

여기서, 원통형 커버는 길이나 구경의 크기에 구애받지 않고 사용 가능하고, 엘이디 형광램프를 점등/점멸시키는 작동관계는 통상의 공지 기술을 채용하고 있음으로 그에 대한 상세한 설명은 생략한다. Here, the cylindrical cover can be used irrespective of the length or the size of the aperture, and the operation relationship for turning on / flashing the LED fluorescent lamp adopts a conventionally known technique, so a detailed description thereof will be omitted.

또한, 원통형 커버에서의 확산 커버는 빛을 잘 방사하는 특성이 좋은 불투명 또는 투명 재질의 공지 기술인 것이다. Further, the diffusion cover in the cylindrical cover is a known technique of an opaque or transparent material having a good light emitting property.

그러므로, 본 발명은 원통형 커버내에서 길게 배치된 엘이디 어레이로부터 발광되는 각 엘이디 빛들이 원형 확산커버에서의 전방측 확산커버와 후방측 차단커버에서의 경계부위에서 명확한 명암부위를 형성함으로 빛이 발산되는 부위가 더욱 선명하게 보여지므로, 종래 조명특성보다 외부에서 엘이디 빛들이 뚜렷하고 깔끔하게 입체조명된다. Therefore, according to the present invention, each LED light emitted from an LED array arranged in a cylindrical cover forms a light and dark region at the boundary between the front diffusion cover and the rear blocking cover in the circular diffusion cover, whereby the light is emitted. Since it is seen more clearly, the LED lights are clearly and neat three-dimensional illumination from the outside than the conventional lighting characteristics.

한편, 상기 실시예에서 후방측 차단커버(30)는 전방측 확산커버(20)와 결합되어 원통형으로 결합되는 것으로 설명되었으나, 반드시 정확한 원형이 아니라 아크형으로 형성될 수도 있고 평면형으로 형성될 수도 있다.Meanwhile, in the above embodiment, the rear side blocking cover 30 has been described as being combined with the front side diffusion cover 20 in a cylindrical shape, but may be formed in an arc shape or a flat shape instead of an exact circular shape. .

이상 설명한 바와 같이, 본 발명은 기존 형광등이 가지는 조명기구의 특성을 최대한 자연스럽고 근접하게 구현함으로써 종래의 형광등과 같이 조명사용이 가능하여 사용자의 사용이 보다 편리한 이점이 있다. As described above, the present invention implements the characteristics of the lighting fixtures of the existing fluorescent lamp as close as possible to the natural, and can be used as a conventional fluorescent lamp, there is an advantage that the user is more convenient to use.

이상 본 발명의 엘이디 형광램프에 의해 구현될 수 있는 바람직한 실시예의 일부에 관하여 설명한 것에 불과하므로, 주지된 바와 같이 본 발명의 범위는 위의 실시예에 한정되어 해석되어서는 안 될 것이며, 위에서 설명된 본 발명의 기술적 사상과 그 근본을 함께하는 기술적 사상은 모두 본 발명의 범위에 포함된다고 할 것이다.Since only a portion of the preferred embodiment that can be implemented by the LED fluorescent lamp of the present invention described above, as is well known the scope of the present invention should not be construed as limited to the above embodiment, as described above It will be said that the technical idea of the present invention and the technical idea of the same together are all included in the scope of the present invention.
