Description

엘이디 투광등LED floodlight

본 발명은 자연대류 방열부를 구비한 방열하우징과 광유도와 방열을 겸하여 수행하는 방열반사갓을 구비함으로써 방열성능이 획기적으로 향상되어 고 입력전력(W)급 엘이디 조명기구인 투광등에 필요ㆍ충분한 방열성능 확보를 통하여 품질특성을 현저히 향상토록 하는 엘이디 투광등에 관한 것이다.The present invention provides a heat dissipation housing having a natural convection heat dissipation unit and a heat dissipation reflector which performs both light induction and heat dissipation. Through the LED floodlight to significantly improve the quality characteristics through.

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 사용되고 있다.Floodlights are used as one of such LED lighting fixtures.

투광등은 일정 방향의 넓은 영역으로 빛을 조사하는 것으로서 광장, 경기장, 항만, 공항, 공사장 등에서 널리 사용되며, 일반 조명기구에 비하여 조명범위가 넓기 때문에 기기의 규모가 크고 엘이디 갯수 및 입력전력(W)이 높으며 이에 비례하여 많은 량의 열이 발생되므로 보다 높은 방열성능이 요구된다.Floodlight is a large area in a certain direction. It is widely used in plazas, stadiums, ports, airports, construction sites, etc., and its lighting range is wider than that of general lighting equipment, so the size of the device is large and the number of LEDs and input power (W ) Is high, and a large amount of heat is generated in proportion to this, and thus higher heat dissipation performance is required.

또한, 투광등을 비롯한 엘이디 조명기구의 방열구성은 엘이디 실장 피씨비가 장착되는 하우징의 일부로 형성되며 방열부를 갖는 하우징의 설계는 조명 발열량에 따라 대응하여 설계되고 조명 발열량은 1개 엘이디의 입력전력(W) 및 엘이디의 수량에 따라 결정된다.In addition, the heat dissipation configuration of the LED lighting fixture including the floodlight is formed as a part of the housing in which the LED mounting PC is mounted, and the design of the housing having the heat dissipation unit is designed according to the light heating amount, and the light heating amount is the input power of one LED (W). ) And the quantity of LEDs.

그런데, 조도를 높이기 위하여 1개 엘이디의 입력전력(W)을 높이거나 엘이디의 수량을 추가하는 설계변경이 이루어질 경우, 기본 설계안에 맞추어 제조된 하우징은 방열성능 문제로 사용이 불가능하여 사장, 폐기되고 새로운 구성의 방열하우징이 필요한 어려움이 있다.However, if a design change is made to increase the input power (W) of one LED to increase the illuminance or to add the quantity of LEDs, the housing manufactured according to the basic design cannot be used due to heat dissipation performance. There is a need for a new heat dissipation housing.

또한, 투광등에는 빛을 일방향으로 유도하기 위한 반사갓이 수반되는데 이 반사갓이 광유도 기능에만 머무르고 있어 아쉬움이 있었다.In addition, the floodlight is accompanied by a reflection shade for guiding light in one direction, which was regrettable because the reflection shade stays only in the light induction function.

본 발명은 상기한 문제점을 해소하기 위한 것으로서,The present invention is to solve the above problems,

본 발명의 목적은 방열하우징이 열기정체를 방지하고 자연대류작용 및 연통효과를 발휘하는 자연대류 방열부를 구비하며, 광유도와 방열을 겸하여 수행하는 방열반사갓을 구비함으로써 방열성능이 획기적으로 향상되어 고 입력전력(W)급 엘이디 조명기구인 투광등에 필요ㆍ충분한 방열성능을 확보토록 하고 이를 통하여 품질특성을 현저히 향상토록 하는 엘이디 투광등을 제공함에 있다.An object of the present invention is a heat dissipation housing has a natural convection heat dissipation unit to prevent thermal stagnation and exhibit a natural convection action and communication effect, and has a heat dissipation reflector that performs a combination of light induction and heat dissipation significantly improved heat dissipation performance is high input It is to provide the LED floodlight to ensure the necessary and sufficient heat dissipation performance for the floodlight, which is a power (W) class LED lighting fixture, and to significantly improve the quality characteristics.
