Description

형광등타입 엘이디 조명기구{FLUORESCENT LAMP TYPE LED LAMP}Fluorescent type LED lighting fixtures {FLUORESCENT LAMP TYPE LED LAMP}

본 발명은 방열프레임에 ∧형 경사부를 구비하여 광원부가 양측에 경사배치됨으로써 조명기구의 폭이 현저히 좁아지므로 설치 및 공간활용을 용이하게 함과 아울러 조도를 균일하게 하며 조명범위가 획기적으로 확장되어 품질특성을 현저히 향상시키며 조명사각지대를 해소토록 하는 형광등타입 엘이디 조명기구에 관한 것이다.The present invention is provided with a U-shaped inclined portion in the heat dissipation frame so that the width of the light fixture is significantly narrowed by the inclined arrangement of the light source on both sides to facilitate the installation and use of space, uniformity of illuminance and the illumination range is greatly expanded quality The present invention relates to a fluorescent type LED lighting fixture that significantly improves the characteristics and eliminates the lighting blind spots.

엘이디(LED: Light Emitting Diode)는 종래의 광원에 비하여 소형이고 수명이 길뿐만 아니라 전기에너지가 빛에너지로 직접 변환되기 때문에 전력이 적게 소모되어 에너지 효율이 우수한 고광도를 발하는 특성을 지니고 있다.LED (Light Emitting Diode) is smaller and longer lifespan than the conventional light source, and because the electric energy is directly converted to light energy, it consumes less power and has a characteristic of emitting high brightness with excellent energy efficiency.

따라서, 이러한 엘이디를 광원으로 하는 다양한 조명기구가 개발되고 있으며, 근래에는 기존의 형광등을 대체할 수 있도록 하는 형광등타입의 엘이디 조명기구가 개시되고 있다.Accordingly, various lighting apparatuses using such LEDs as light sources have been developed, and recently, fluorescent light-type LED lighting apparatuses capable of replacing existing fluorescent lamps have been disclosed.

형광등타입의 엘이디 조명기구는 기존의 형광등 프레임 구조물에 상응하여 양측에 단자가 구비되는 케이싱 내에 엘이디를 포함하는 광원부가 설치되어 구성되며, 상기 광원부는 길이가 긴 피씨비 상에 설정간격으로 엘이디가 배열 실장되어 이루어진다.Fluorescent lamp type LED lighting fixture is configured by installing a light source unit including the LED in the casing having a terminal on both sides corresponding to the existing fluorescent frame structure, the light source unit is mounted on the long length of the PCB in the set intervals It is done.

또한, 조도를 높이기 위하여 일반 형광등에서 하나의 프레임 구조물 내에 두개의 램프를 나란히 설치하는 것과 같이 광원부를 두개 라인 설치하고 있기도 하다.In addition, in order to increase the illuminance, two lines of light sources may be installed, such as installing two lamps side by side in a frame structure in a general fluorescent lamp.

그런데, 종래기술(100)에서는 도 6에 도시된 바와 같이 프레임(120)에 광원부탑재대(121)가 수평으로 나란히 형성됨으로써 광원부(110)가 탑재되는 프레임의 폭(120W)이 넓게 형성되어야 하므로 설치공간을 크게 차지하여 공간활용을 어렵게하고 설치가 불편한 문제점이 있었다.However, in the prior art 100, as shown in FIG. 6, since the light source unit mounting base 121 is horizontally formed side by side in the frame 120, the width 120W of the frame on which the light source unit 110 is mounted should be widened. It occupies a large space for installation, making space utilization difficult and inconvenient to install.

또한, 광원부가 수평으로 나란히 배치됨에 따라 빛 확산 폭이 좁은 엘이디의 특성으로 인하여 도 7에 도시된 바와 같이, 조명영역의 조도가 불균일한 문제점이 있다.In addition, as the light source units are arranged side by side horizontally, as shown in FIG. 7 due to the characteristics of the LED having a narrow light spreading width, there is a problem that the illuminance of the illumination region is uneven.

즉, 엘이디는 조사각(L)이 대개 110° 내외로 되고 광량의 50%가 중앙 30° 범위(L1)에 집중되는데 상기와 같이 광원부가 수평설치됨으로써 전체적으로 30° 범위(L6) 내로 빛이 집중될 뿐만 아니라 광 발산 온각이 110° 범위(L7)에 그쳐 측방향은 조도가 떨어지고 외곽은 조명 사각지대로 되는 등 조도편차가 심한 문제점이 있다.That is, the LED usually has an irradiation angle L of about 110 °, and 50% of the light is concentrated in the center 30 ° range L1. As described above, the light source unit is horizontally installed, so that the light concentrates within the 30 ° range L6. In addition, the light divergence temperature is only 110 ° range (L7), the lateral roughness is lowered, the outer edge is a blind spot, such as the illumination roughness is a serious problem.

또한, 전원구동부가 프레임 외부에 별도 설치됨으로써 현장 설치작업 및 취급이 대단히 번거로운 어려움이 있다.In addition, since the power supply unit is separately installed outside the frame, the field installation work and handling are very troublesome.

본 발명은 상기한 문제점을 해소하기 위하여 안출된 것으로서,The present invention has been made to solve the above problems,

본 발명의 목적은 방열프레임에 ∧형 경사부를 구비하여 광원부가 양측에 경사배치됨으로써 조명기구의 폭이 현저히 좁아지므로 설치 및 공간활용을 용이하게 함과 아울러 조도를 균일하게 하며 조명범위가 획기적으로 확장되어 품질특성을 현저히 향상시키며 조명사각지대를 해소토록 하는 형광등타입 엘이디 조명기구를 제공함에 있다.An object of the present invention is to include a U-shaped inclined portion in the heat radiation frame, the light source is inclined on both sides, so the width of the lighting fixture is significantly narrowed, facilitates the installation and use of space, uniformity of illumination, and the illumination range is significantly expanded It is to provide a fluorescent lamp type LED lighting fixture that significantly improves the quality characteristics and eliminates the lighting blind spots.

본 발명에 따른 일 실시예로서, 도 4에 도시된 바와 같이, 상기 방열프레임(20)은 방열부(27)가 연장형성되어 내측에 전원구동부 수용공간(23)을 확보하여 광원부(10a)(10b)의 설치 및 방열과 전원구동부(70)의 수용을 단일체로 수행함이 바람직하다.As shown in FIG. 4, as shown in FIG. 4, the heat dissipation frame 20 has a heat dissipation part 27 extending to secure the power driver accommodating space 23 therein.

본 발명의 방열프레임(20)은 알루미늄 등으로 압출성형되고 보강 및 방열성 능을 높이기 위하여 요철이 길이방향으로 형성될 수 있다. The heat dissipation frame 20 of the present invention may be extruded from aluminum, etc., and the unevenness may be formed in the longitudinal direction to increase the reinforcement and heat dissipation performance.

이와 같은 구성을 지닌 본 발명에 따른 형광등타입 엘이디 조명기구(1)의 작용상태를 살펴본다.It looks at the working state of the fluorescent lamp type LED lighting device (1) according to the present invention having such a configuration.

본 발명은 방열프레임이 상부가 단면상 ∧형 경사부(20a)로 형성되고 상기 ∧형 경사부(20a)의 양측에 각각 광원부탑재대(21a)(21b)가 경사형성됨으로써 종래 기술에 비하여 방열프레임의 폭(20W) 및 조명기구의 폭이 현저히 좁아진다.According to the present invention, the heat dissipation frame is formed in the upper portion of the U-shaped inclined portion 20a on the cross-section, and the light source portion mounting bases 21a and 21b are inclined on both sides of the X-shaped inclined portion 20a, respectively. The width 20W and the width of the lighting fixtures are significantly narrowed.

따라서, 설치공간 폭이 좁아져 공간점유가 현저히 줄며 공간활용을 용이하게 한다. Therefore, the width of the installation space is narrowed, which significantly reduces the space occupancy and facilitates the space utilization.

또한, 본 발명은 광원부(10a)(10b)가 ∧형 경사부(20a)의 양측에 형성된 광원부탑재대(21a)(21b)를 이용하여 경사지게 설치됨으로써 빛의 조도가 조명영역 전체적으로 균일하게 된다.In addition, in the present invention, since the light source portions 10a and 10b are inclined using the light source portion mounting bases 21a and 21b formed on both sides of the X-shaped inclined portion 20a, the illuminance of the light is uniform throughout the illumination region.

상술한 바와 같이, 엘이디(11)로부터 발사되는 빛은 광유도 확산수단(60)에서 110°내외 범위로 입사 확산되되 중심 30° 범위 안에 광량의 50% 이상이 집중되는데 설명을 위하여 광량이 집중되는 광집중범위를 'L1'이라 하고 상대적으로 광량이 적은범위를 'L2'라 할 때, 본 발명은 도 5에 도시된 바와 같이, 두 라인의 광원부(10a)(10b)가 대칭으로 경사형성됨으로써 조명 중앙부 하방은 양측 광원부(10a)(10b)의 광량이 적은 범위(L2)가 겹쳐져 광집중범위와 조도가 균등하게 되는 한편 광집중범위(L1)의 외향 각도가 현저히 확장되면서 전체 조명영역의 조도가 균일화되고 조명사각지대가 해소된다.As described above, the light emitted from the LED 11 is incident diffused in the light induction diffusing means 60 in a range of about 110 °, but more than 50% of the light is concentrated in the center 30 ° range, for which the light amount is concentrated. When the light concentration range is referred to as 'L1' and the range where the light amount is relatively small as 'L2', the present invention is as shown in FIG. 5 by forming the two light source portions 10a and 10b symmetrically inclined. Below the center of the illumination, the area L2 of both light sources 10a and 10b overlaps with each other so that the light concentration range and illuminance become equal, while the outward angle of the light concentration range L1 is significantly expanded, and thus the illuminance of the entire illumination area. Is uniform and the lighting blind spot is eliminated.

예컨대, ∧형 경사부(20a)의 경사각(θ1)이 45°일 경우 경사 형성되는 두 라인의 광원부(10a)(10b)가 형성하는 광집중범위 온각(L3)이 120°가 되고, 광량이 적은 범위(L2)를 포함하는 온각(L4)은 200°가 되어 빛의 조도가 균일하게 넓은 범위로 확산된다.For example, when the inclination angle θ1 of the X-shaped inclination portion 20a is 45 °, the light intensity range warm angle L3 formed by the light source portions 10a and 10b of the two lines which are inclined is 120 °, and the amount of light is The warm angle L4 including the small range L2 becomes 200 ° so that the illuminance of light is uniformly diffused over a wide range.

그리고, 상기 ∧형 경사부(20a)는 용도에 따라 경사각(θ1)을 달리 형성함으로써 조사각도를 조정할 수 있다.In addition, the angle of inclination of the X-shaped inclined portion 20a may be adjusted by forming an inclined angle θ1 differently according to a use.

한편, 광원부는 방열프레임(20) 광원부탑재대(21) 일측에 형성된 경사파지면(213)과 타측에 체결되는 스크류의 머리 경사면(41)에 의하여 파지되므로 피씨비(13) 폭방향 좌우 중에서 한쪽 방향 스크류(40) 체결만으로 고정이 이루어짐으로써 조립생산성을 높이고, 경사파지면(213) 및 스크류 머리의 경사면(41)을 이용함으로써 피씨비의 높이 차이가 날 경우에도 신축적으로 대응된다(도 3 참조).Meanwhile, the light source unit is gripped by the inclined wave surface 213 formed on one side of the heat dissipation frame 20 and the light source unit mounting base 21 and the head inclined surface 41 of the screw fastened to the other side. Fixing is performed only by fastening the screw 40, thereby increasing assembly productivity, and by using the inclined wave surface 213 and the inclined surface 41 of the screw head, even when there is a difference in the height of the PC, it is elastically supported (see FIG. 3). .

또한, 전원구동부(70)가 방열프레임 내에 형성되는 전원구동부 수용공간(23)에 내설됨으로써 구성이 간편해지고 설치공간을 줄여주는 장점을 갖는다(도 4 참조).In addition, since the power driver 70 is installed in the power driver accommodating space 23 formed in the heat dissipation frame, the configuration is simplified and the installation space is reduced (see FIG. 4).

또한, 주차장 등 공중에 설치시에는 상기 행거결합부(25) 및 상기 행거결합부에 끼워지고 건축물 천장에서 늘어뜨려지는 행거(3)를 이용한다.In addition, when installing in the air, such as a parking lot, the hanger coupling part 25 and the hanger 3 fitted to the hanger coupling part and hang down from the ceiling of a building are used.

이와 같은 본 발명은 방열프레임이 ∧형 경사부(20a)를 구비하여 광원부탑재대(21a)(21b)가 양측에 경사형성됨으로써 폭(20W)이 현저히 좁아지고 이에 따라 설치공간 폭이 좁아져 공간활용을 용이하게 함과 아울러 조도가 균일하게 조명범위가 획기적으로 확장되어 품질특성을 향상시키며 조명사각지대를 해소한다.In the present invention as described above, the heat radiation frame is provided with an inclined portion 20a so that the light source unit mounting bases 21a and 21b are inclined on both sides, thereby significantly narrowing the width 20W and thus narrowing the installation space width. In addition to facilitating application, the illumination range is evenly expanded to improve the quality characteristics and eliminate the lighting blind spots.
