엘이디 투광등{LED FLOODLIGHT}LED Flood Light {LED FLOODLIGHT}

본 발명은 광유도와 방열을 겸하여 수행하는 방열반사갓을 구비하여 방열성능을 획기적으로 향상시킴으로써 종래기술에서 수반되던 별도의 방열부재를 배제시키고 경량 소형화되어 취급관리가 현저히 용이하며 제조비용 및 물류비용을 절감토록 하는 엘이디 투광등에 관한 것이다.The present invention is provided with a heat radiation reflector to perform a combination of light induction and heat dissipation to significantly improve the heat dissipation performance by eliminating the separate heat dissipation member that was involved in the prior art and lightweight and compact, significantly easier handling management and reduce manufacturing costs and logistics costs It's about LED floodlights.

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 특장점으로 조명기구의 광원으로 다양하게 개발되고 있다.LED (Light Emitting Diode) is a feature that emits high brightness with high energy efficiency because it consumes less power because electric energy is directly converted to light energy, and it is small and longer than conventional light sources. It is developed variously.

한편으로 엘이디는 점등시 열이 발생되고, 방열이 원활하게 되지 못할 경우 조도가 급격히 저하될 뿐만 아니라 수명이 현저히 단축되므로 엘이디 조명기구의 품질특성은 방열성능에 의하여 좌우된다고 할 수 있다.On the other hand, when the LED is turned on, heat is generated, and if the heat dissipation is not smooth, not only the illuminance is drastically reduced but also the life is remarkably shortened, so the quality characteristics of the LED lighting fixtures can be said to depend on the heat dissipation performance.

이러한 엘이디 조명기구의 하나로서 투광등이 있다.One such LED lighting device is a floodlight.

투광등은 일정 방향으로 빛을 조사하는 것으로서 특정 조형물에 투사하는 투광조명, 넓은 면적을 조명하는 광장조명, 경기장, 항만, 공항, 공사장 등에서 널리 사용되는 조명기구이다.Floodlight is a light fixture that irradiates light in a certain direction and is widely used in floodlights projecting on a specific sculpture, square lighting that illuminates a large area, stadiums, harbors, airports, and construction sites.

이러한 투광등은 일반 조명기구에 비하여 조명범위가 넓기 때문에 광원인 엘이디 모듈의 용량 및 기기의 규모가 크고 발열 또한 비례하여 많은 량이 발생되므로 보다 높은 방열성능이 요구된다.Since the floodlight has a wider lighting range than a general lighting device, the capacity of the LED module, which is a light source, and the size of the device are large, and a large amount of heat is generated.

본 발명의 다른 목적은 엘이디를 광원으로 하는 조명기구의 과제인 방열성능을 충분히 확보하여 품질특성을 현저히 향상토록 하는 엘이디 투광등을 제공함에 있다.Another object of the present invention is to provide an LED floodlight to ensure a sufficient heat dissipation performance of the luminaire using the LED as a light source to significantly improve the quality characteristics.

이와 같은 구성을 지닌 본 발명에 따른 엘이디 투광등(1)의 작용상태를 살펴 본다.Looking at the working state of the LED floodlight (1) according to the present invention having such a configuration.

본 발명은 투광등에서 방열반사갓(50)이 방열수단을 겸하도록 흡열접합부(51)를 구비하여 되고 방열하우징(30)에 열교환 가능하게 접합됨으로써 방열면적이 획기적으로 넓어지고 충분한 방열성능을 확보한다.In the present invention, the heat radiation reflector 50 is provided with a heat absorbing junction 51 to serve as a heat dissipation means in a floodlight, and the heat dissipation is joined to the heat dissipation housing 30 so that the heat dissipation area is significantly widened to ensure sufficient heat dissipation performance.

다시 말하면, 광원부(10)의 빛을 일정 방향으로 유도하기 위하여 넓은 면적을 갖는 방열반사갓(50)이 흡열접합부(51)가 광원설치부(311)에 인접 접합됨으로써 광원부로부터 발생된 열을 흡열하고 넓은 면적으로 열교환 방출하는 방열기능을 수행하여 광원부(10)의 방열이 효과적으로 이루어진다.In other words, the heat radiation reflector 50 having a large area absorbs heat generated from the light source unit by bonding the heat absorbing junction unit 51 adjacent to the light source installation unit 311 so as to guide the light of the light source unit 10 in a predetermined direction. By performing a heat dissipation function of heat exchange and release in a large area, heat dissipation of the light source unit 10 is effectively performed.

또한, 방열반사갓(50)에서 광원부(10)로부터 멀리 위치하는 선단(55)이 타원으로 형성될 경우 예컨대 건축물에 대한 투광시 배광곡선이 효과적으로 이루어진다. In addition, when the tip 55 located far from the light source unit 10 in the heat radiation reflector 50 is formed as an ellipse, for example, a light distribution curve is made when the light is emitted to the building.

또한, 방열반사갓(50)이 광확산을 위하여 예컨대 다이아몬드 패턴의 다면체로 형성되고 광원부(10)에 볼록렌즈로 기능하는 볼록돌기(71)가 엘이디 배열에 대응하여 배열형성된 렌즈(70)가 설치됨으로써 빛 집중특성을 갖는 엘이디(11)의 빛을 균일하게 확산시킨다.In addition, since the heat radiation reflector 50 is formed of a polyhedron with a diamond pattern for light diffusion, for example, a lens 70 having a convex protrusion 71 functioning as a convex lens arranged in correspondence with the LED array is installed in the light source unit 10. The light of the LED 11 having the light concentration characteristic is uniformly diffused.

또한, 방열하우징(30)에 형성되는 자연대류 방열부(33)는 도 1, 2, 6에 도시된 바와 같이, 광원설치부(311) 주위에 방사상으로 베이스방열핀(331)이 형성되고 수직관형태의 방열테(333)가 구비되어 방열테(333)와 본체부(31) 사이에 자연대류를 촉진시키는 수직방향 공기통로(335)가 형성됨으로써 방열성능을 획기적으로 향상시킨다.In addition, the natural convection heat dissipation unit 33 formed in the heat dissipation housing 30 has a base heat dissipation fin 331 formed radially around the light source installation unit 311 as shown in FIGS. The heat radiation frame 333 of the form is provided between the heat radiation frame 333 and the main body portion 31 is formed in the vertical air passage 335 for promoting natural convection to significantly improve the heat dissipation performance.

즉, 광원부(10)의 열을 흡수 방열하는 본체부(31) 주위에 수직방향 공기통로(335)가 형성되어 방열교환으로 데워진 공기가 상승하고 그 자리에 상온의 공기가 유입되는 자연대류가 이루어짐으로써 열기정체를 방지하고 방열이 신속하게 이루어진다.That is, a vertical air passage 335 is formed around the body portion 31 absorbing and radiating heat of the light source unit 10 so that the air warmed by heat exchange exchange rises and natural air flows into the air at room temperature. This prevents thermal stagnation and quickly dissipates heat.

이와 같이 상기 방열반사갓(50) 및 자연대류 방열부(33)를 구비하는 방열하우징(30)에 의하여 방열성능이 획기적으로 향상됨으로써 별도의 방열장치를 덧붙일 필요가 없어 중량이 현저히 경감되고 부피가 줄어 취급이 현저히 용이하며 제조비용 및 물류비용이 절감된다.In this way, the heat dissipation performance is dramatically improved by the heat dissipation housing 30 having the heat dissipation reflector 50 and the natural convection heat dissipation unit 33, so that it is not necessary to add a separate heat dissipation device, and the weight is significantly reduced and the volume is reduced. The handling is remarkably easy and the manufacturing and logistics costs are reduced.

또한, 이와 같은 방열성능 향상에 따른 경량화로 나사결합식 소켓에 리셉터클(60)을 이용하여 전기적 결합 및 지지가 가능하다.In addition, it is possible to electrically couple and support using the receptacle 60 to the screw-type socket due to the weight reduction according to the improvement of the heat dissipation performance.

또한, 본 발명은 방열하우징(30)에 힌지(91)결합되는 지지장치(90)를 통하여 기울기조정이 용이하게 구조물에 설치된다.In addition, the present invention is easily installed on the structure through the support device 90, the hinge 91 is coupled to the heat dissipation housing 30, the structure.

이상과 같이, 본 발명에 따른 엘이디 투광등은 광유도와 방열을 겸하여 수행하는 방열반사갓을 구비함으로써 방열성능이 획기적으로 향상되어 종래기술에서 수반되던 별도의 방열부재가 배제되고 경량 소형화되어 취급관리가 현저히 용이하며 제조비용이 현저히 절감됨과 아울러 엘이디를 광원으로 하는 조명기구의 과제인 방열성능을 충분히 확보하여 조도를 유지하면서 수명을 극대화시킨다.As described above, the LED floodlight according to the present invention is provided with a heat radiation reflector to perform both heat induction and heat radiation, the heat dissipation performance is significantly improved, eliminating the separate heat dissipation member that was involved in the prior art, and light weight and compact size, handling management significantly It is easy and the manufacturing cost is remarkably reduced, and the heat dissipation performance, which is the task of the luminaire using the LED as a light source, is sufficiently secured to maximize the life while maintaining the illuminance.

이상, 본 발명은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능하므로 전술한 실시예 및 도면에 한정되는 것은 아니다.As described above, the present invention may be variously substituted, modified, and changed within the scope without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains.
