Description

조사각을 조절할 수 있는 엘이디 조명장치LED lighting device with adjustable irradiation angle
본 발명은 사용자가 원하는 조사영역에 맞게 조사각을 조절할 수 있음과 동시에 높은 배광효율을 가지는 LED 조명장치에 관한 것이다.The present invention relates to an LED lighting device having a high light distribution efficiency while being able to adjust the irradiation angle according to a user's desired irradiation area.
일반적으로 도로상에 설치되는 종래의 가로등은 도로를 따라서 대략 30M 내지 50M의 간격으로 일정하게 배치되고, 조명등으로서는 통상 나트륨등이나 일반 메탈 등을 사용하는 것이 일반적이었다. 그러나 이와 같은 종래의 나트륨등이나 메탈 등의 조명등은 방전식으로서 전력이 많이 소모되어 전기낭비가 심하였기 때문에 LED칩을 광원으로서 사용하는 가로등용 조명등이 개발되었다.In general, the conventional street lamps installed on the road are regularly arranged at intervals of approximately 30M to 50M along the road, and it is common to use sodium lamps or ordinary metals as lighting lamps. However, such a conventional lighting lamp such as sodium or metal, such as a discharge type consumes a lot of power and wasted electrical consumption, so a lamp for a street lamp using an LED chip as a light source has been developed.
이와 같이 LED 칩을 광원으로서 사용하는 가로등용 조명등은 대부분 용량이 높은 파워 LED 칩(power LED chip)을 광원으로서 사용하고 있으며, 이들을 다수 개 조립하여 패키지화하여 사용하는 것이었다. 그러나 LED를 광원으로 사용하는 가로등은 LED 광원의 특성이 직 방향성이므로 설치장소에 따라 조사각을 넓고 좁게 조절이 불가능하여 항상 일정한 각도로 밖에 비출 수 없는 문제가 따르게 되었다. As described above, the lamps for street lamps using the LED chip as a light source mostly use a high power LED chip as a light source, and many of them are assembled and packaged. However, the street light using LED as a light source has a problem that the characteristics of the LED light source are direct, so that the irradiation angle can not be adjusted widely and narrowly depending on the installation location, so that it can always be illuminated only at a certain angle.
더욱 상세하게 설명하면 LED 칩을 사용하는 조명등은 보통 가로등이 30M 내지 50M의 간격으로 설치됨에 비추어 볼 때, 가로등 사이에 조명이 비춰지지 않아 매우 어두운 소위 사각지대가 존재하게 된다. 즉 종래의 LED 칩사용 조명등은 LED의 확산성 부족으로 인하여 가로등과 가로등 사이에서는 광량이 아주 적어서 어두운 소위 사각지대를 빈번하게 형성하는바, 이와 같은 사각지대는 야간에 차량 통행의 어려움은 물론, 보행자들이 안전하게 이동하는데 큰 장애를 주었다.In more detail, lighting lamps using LED chips are usually installed at intervals of 30M to 50M, so that there is a very dark so-called blind spot because there is no illumination between the street lamps. In other words, the conventional LED chip lighting lamps have a very small amount of light between the street lamps and the street lamps due to the lack of diffusion of LEDs, and thus frequently form dark so-called blind spots. It gave them a big obstacle in moving safely.
본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로서, 사용자가 원하는 조사영역에 맞춰 조사각을 조절하여 사용할 수 있으며, 발열효율이 뛰어나 내구성이 우수하고 동일한 조도율에도 다른 조명장치에 비해 높은 배광율을 가질 수 있는 조사각을 조절할 수 있는 LED 조명장치의 마련을 목적으로 한다.The present invention has been devised to solve the above problems, and can be used by adjusting the irradiation angle according to the user's desired irradiation area, excellent heat generation efficiency, excellent durability and high light distribution in comparison with other lighting devices An object of the present invention is to provide an LED lighting device that can adjust an irradiation angle that can have a rate.
상기와 같은 목적을 달성하기 위하여 본 발명에서는 후단에 방열부가 구비되는 LED 조명등과 상기 방열부가 결합되는 설치홈이 형성된 방열판을 포함하되, 상기 방열판에는 상기 조명등의 설치각도를 조절하여 결합할 수 있는 조사각을 조절할 수 있는 LED 조명장치를 제안한다.In order to achieve the above object, the present invention includes a heat dissipation plate formed with an LED lighting lamp having a heat dissipation unit at the rear end and an installation groove to which the heat dissipation unit is coupled, and irradiating the heat dissipation plate by adjusting an installation angle of the light. We propose an LED lighting device that can adjust the angle.
본 발명은 설치 상황에 따라 조도 영역을 사용자가 선택적으로 조절하여 사용할 수 있음과 동시에 다른 조명등과 동일한 조도량에도 다량의 반사광을 외부로 방출하여 뛰어난 배광율을 가짐으로써 사용상 효용성이 뛰어나며 LED의 확산성 부족으로 인해 빛이 비춰지지 않는 조명 사각지대가 발생되는 것을 최소화할 수 있는 것이다. The present invention can be used by the user to selectively adjust the illuminance area according to the installation situation and at the same time as the other illumination lamps emit a large amount of reflected light to the outside to have an excellent light distribution rate and excellent in use efficiency and diffusion of LED It is possible to minimize the lack of light blind spots due to lack of light.
