Description

자유로운 배광을 만들 수 있는 LED 가이드{LED guide to be able to make free distribution}LED guide to be able to make free distribution}

본 발명은 자유로운 배광을 만들 수 있는 LED 가이드에 관한 것으로, 보다 상세하게는 표준모듈의 LED 등기구를 단일 발광기구로 그대로 사용하면서도 별도의 칩을 부가하거나 혹은 별도의 확산판이나 반사갓을 사용하지 않고도 배광가이드의 높낮이 조절만으로도 자유로운 배광이 가능하고, 동시에 발광에 따른 방열효율도 향상시켜 배광성과 발광성이 양립 가능한 상태로 모두 높여 LED 등기구의 효율을 극대화시킬 수 있도록 개선된 자유로운 배광을 만들 수 있는 LED 가이드에 관한 것이다.The present invention relates to an LED guide that can make free light distribution, and more specifically, light distribution without adding a separate chip or using a separate diffuser or reflector while using the standard module's LED luminaire as a single light emitting device as it is. It is possible to freely distribute light only by adjusting the height of the guide, and at the same time improve the heat dissipation efficiency according to the light emission, so that both light distribution and luminous properties are compatible. it's about

LED(Light Emitting Diode) 등기구는 전기의 공급에 의해 소정의 파장을 가지는 광을 발광하는 LED를 이용한 조명장치이다.An LED (Light Emitting Diode) luminaire is a lighting device using an LED that emits light having a predetermined wavelength by supplying electricity.

이러한 LED 등기구는 전류 인가에 의해 P-N 반도체 접합(P-N junction)에서 전자와 정공이 만나 빛을 발하는 소자로서, 통상 LED 칩이 탑재된 패키지의 구조로 제작된다.Such an LED luminaire is a device that emits light when electrons and holes meet at a P-N junction by applying a current, and is usually manufactured in a package structure in which an LED chip is mounted.

이와 같은 LED 패키지는 일반적으로 인쇄회로기판(PCB:Printed Circuit Board) 상에 장착되어 그 인쇄회로기판에 형성된 전극으로부터 전류를 인가받아 발광 동작하도록 구성된다.Such an LED package is generally mounted on a printed circuit board (PCB) and configured to emit light by receiving a current from an electrode formed on the printed circuit board.

그런데, LED에서 방출되는 빛은 직진성이 매우 강하기 때문에 고정적인 배광에서 벗어날 수 없어 그 효율성을 100% 활용할 수 없다는 한계가 있다.However, since the light emitted from the LED has a very strong straightness, it cannot escape from the fixed light distribution, so there is a limitation that the efficiency cannot be used 100%.

때문에, 현존하는 LED 등기구는 렌즈를 이용하여 빛의 조사범위를 확장하거나 혹은 확산판이나 반사갓을 이용하여 고정적인 배광을 벗어나도록 다양한 시도들이 이루어지고 있다.Therefore, various attempts are being made to extend the light irradiation range using a lens or to deviate from a fixed light distribution using a diffuser plate or a reflector shade in existing LED luminaires.

결국, LED 등기구는 단일 발광기구로 구성되기 어렵고, 다수의 칩을 이용하여 렌즈를 통해 빛을 멀리 보내거나 혹은 반사판이나 확산판을 이용하여 조사범위를 높일 수 밖에 없다.As a result, it is difficult for an LED luminaire to be composed of a single light emitting device, and a plurality of chips are used to send light far away through a lens, or a reflection plate or a diffuser plate is used to increase the irradiation range.

이에 따라, [선행기술문헌] 처럼 등기구의 구조 자체가 변형되고 복잡해서 열발산, 즉 방열효율이 떨어짐으로써 등기구의 수명이 단축되는 한계에 도달해 있다.Accordingly, as in [Prior Art Document], the structure of the luminaire itself is deformed and complicated, so that heat dissipation, ie, heat dissipation efficiency, is reduced, and thus the life span of the luminaire is reduced.

뿐만 아니라, 과도하게 많은 칩을 이용한 배광기술은 균일한 조도를 형성하기 어렵고, 빛의 효율성을 나쁘게 하여 가로등, 보안등, 터널등, 경관조명 등으로 활용될 때 보행자 혹은 운전자의 국부적인 눈부심을 유발하여 안전사고를 발생시키고, 수면방해, 생태교란 등을 일으키기도 한다.In addition, the light distribution technology using too many chips makes it difficult to form a uniform illuminance, and causes local glare for pedestrians or drivers when used as street lights, security lights, tunnel lights, and landscape lights by worsening light efficiency. This can lead to safety accidents, sleep disturbance, and ecological disturbance.

특히, 배광성이 좋으면 방열성이 떨어져 수명이 단축되고, 방열특성이 향상되면 배광특성이 저하되는 등 배광성과 방열성을 서로 양립하기 어려운 것이 현재 LED 등기구의 한계이기도 하다.In particular, if the light distribution property is good, the heat dissipation property is reduced, and the lifespan is shortened. When the heat dissipation property is improved, the light distribution property is deteriorated.

Free light distribution is possible only by adjusting the height of the light distribution guide without doing so, and at the same time, the improved free light distribution can be made to maximize the efficiency of LED luminaires by improving the heat dissipation efficiency according to the light emission so that both light distribution and luminous properties are compatible.

또한, 상기 방열폭부(310)에는 상기 내측면과 직교되는 면 상에 형성된 다수의 방열구멍(320)을 더 포함하는 것에도 그 특징이 있다.In addition, the heat dissipation width portion 310 is characterized in that it further includes a plurality of heat dissipation holes 320 formed on a surface orthogonal to the inner surface.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of describing embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as being limited to the embodiments described herein.

도 1에 예시된 바와 같이, 본 발명에 따른 자유로운 배광을 만들 수 있는 LED 가이드는 본체하우징(100)을 포함한다.As illustrated in FIG. 1 , the LED guide capable of making free light distribution according to the present invention includes a body housing 100 .

상기 본체하우징(100)은 다양한 형상으로 제조될 수 있으며, LED 등기구에 맞도록 설계됨이 바람직하다.The body housing 100 may be manufactured in various shapes, and is preferably designed to fit an LED luminaire.

그리고, 상기 본체하우징(100)의 하면에는 적어도 2개 이상의 모듈홈(110)이 형성되고, 상기 모듈홈(110)에는 각각 LED모듈(200)이 장착된다.In addition, at least two or more module grooves 110 are formed on the lower surface of the main housing 100 , and the LED modules 200 are mounted in each of the module grooves 110 .

이때, 상기 LED모듈(200)은 인쇄회로기판에 다수의 LED가 실장된 것으로 본체하우징(100) 내부로 배선되어 전원을 공급받고 온오프 제어될 수 있도록 구성되어 있는데 이는 공지된 구조이므로 상세한 설명은 생략한다.At this time, the LED module 200 is configured such that a plurality of LEDs are mounted on a printed circuit board and are wired inside the main housing 100 to receive power and to be controlled on/off. omit

아울러, 상기 모듈홈(110)에는 도 2와 같은 배광가이드(300)가 고정된다.In addition, the light distribution guide 300 as shown in FIG. 2 is fixed to the module groove 110 .

상기 배광가이드(300)는 알루미늄으로 성형되며, 틀체 형태를 갖는다.The light distribution guide 300 is formed of aluminum and has a frame shape.

이러한 배광가이드(300)는 열전도율이 매우 우수한 알루미늄 재질로 되어 있고 또한 LED모듈인 LED칩과 접촉되어 있으므로 LED칩에서 발생된 열이 배광가이드(300)를 타고 전도되어 외부로 발산, 즉 방출됨으로써 LED칩을 식혀 주어 LED칩이 열에 의해 열화되는 것을 효과적으로 차단한다.Since the light distribution guide 300 is made of an aluminum material having very good thermal conductivity and is in contact with the LED chip, which is an LED module, the heat generated from the LED chip is conducted on the light distribution guide 300 and radiated to the outside, that is, the LED is emitted. By cooling the chip, it effectively blocks the deterioration of the LED chip by heat.

이와 같은 냉각기능을 효과적이고 효율적으로 수행하기 위해 배광가이드(300)의 두께도 특정범위 내에 이르도록 두껍게 설정된다.In order to effectively and efficiently perform such a cooling function, the thickness of the light distribution guide 300 is also set to be thick within a specific range.

특히, 길이방향 양단, 즉 양측 단변에는 방열폭부(310)가 형성되는데, 상기 방열폭부(310)의 폭(W)은 10mm 내에서 형성될 수 있다.In particular, the heat dissipation width portion 310 is formed at both ends in the longitudinal direction, that is, both short sides, and the width W of the heat dissipation width portion 310 may be formed within 10 mm.

그리고, 상기 방열폭부(310)에는 각각 다수의 방열구멍(320)이 형성되는데, 상기 방열구멍(320)은 6mm의 직경을 가짐이 바람직하다.In addition, a plurality of heat dissipation holes 320 are formed in the heat dissipation width portion 310, respectively, and the heat dissipation holes 320 preferably have a diameter of 6 mm.

여기에서, 상기 방열구멍(320)은 외부 찬공기가 유입되어 LED칩, 즉 LED모듈로부터 전달되어 온 열과 원활하게 열교환되도록 유도하는 포켓이며, 방열폭부(310)를 빠르게 공냉시키므로 방열효율이 향상되어 배광성과 방열성을 모두 만족시킬 수 있게 된다.Here, the heat dissipation hole 320 is a pocket that induces external cold air to flow in and smoothly exchange heat with the hot heat transferred from the LED chip, that is, the LED module. Both light distribution and heat dissipation properties can be satisfied.

또한, 상기 방열폭부(310)는 일측 방열폭부의 높이인 제1높이(H1)가 타측 방열폭부의 높이인 제2높이(H2) 보다 높게 구성되어야 한다.In addition, the heat dissipation width portion 310 should be configured such that the first height H1, which is the height of the heat dissipation width portion on one side, is higher than the second height H2, which is the height of the heat dissipation width portion on the other side.

이 경우, 상기 제1높이(H1)와 제2높이(H2)는 서로 일정단차를 갖도록 하되, 최소 6mm에서 최대 20mm의 범위내에서 자유롭게 조절할 수 있다.In this case, the first height H1 and the second height H2 have a predetermined step difference from each other, and can be freely adjusted within a range of at least 6 mm to a maximum of 20 mm.

이렇게 조절하는 이유는 상호간의 두께 단차에 따라 배광폭, 즉 배광거리가 달라지기 때문에 다양하고 자유로운 배광이 가능하도록 하기 위한 것이다.The reason for this adjustment is to enable various and free light distribution because the light distribution width, that is, the light distribution distance varies according to the thickness step between them.

뿐만 아니라, 6mm 미만일 경우에는 배광효율이 떨어지고, 20mm를 초과하면 배광불량으로 LED 등기구를 구현할 수 없기 때문에 상기 범위로 한정해야 한다.In addition, if it is less than 6mm, the light distribution efficiency is lowered, and if it exceeds 20mm, the LED luminaire cannot be implemented due to poor light distribution, so it should be limited to the above range.

한편, 상기 방열폭부(310)의 내측면은 도 3 및 4의 예시와 같이, 마루(330)와 골(340)로 이루어진다.On the other hand, the inner surface of the heat dissipation width portion 310 is composed of a floor 330 and a valley 340 as shown in FIGS. 3 and 4 .

이때, 상기 마루(330)는 일정폭의 수평면을 갖고, 상기 골(340)은 'V'형상의 개선홈 형태를 갖는다.At this time, the floor 330 has a horizontal plane of a certain width, and the valley 340 has a 'V' shape improvement groove shape.

이에 따라, 상기 마루(330)의 수평면과, 상기 골(340)의 양측 경사면은 각각 반사면을 형성하게 되고, LED모듈(200)에 실장된 LED(210)로부터 출사된 빛이 반사되면서 배광폭을 크게 한다.Accordingly, the horizontal surface of the floor 330 and the inclined surfaces on both sides of the valley 340 form reflective surfaces, respectively, and the light emitted from the LED 210 mounted on the LED module 200 is reflected and the light distribution width make it large

이를 위해, 상기 골(340)의 개선각은 105-110°를 유지해야만 조도의 효율성을 높일 수 있다.To this end, the improvement angle of the valley 340 must be maintained at 105-110° to increase the efficiency of illumination.

만약, 개선각이 110°를 초과하게 되면 비록 배광폭이 더 커지기는 하지만, 조도의 균일성을 넘게 되어 불균일화됨으로써 어두워지는 단점이 있고, 105°미만이 되면 배광폭이 커지지 않아 배광효율을 높일 수 없다.If the improvement angle exceeds 110°, although the light distribution width becomes larger, there is a disadvantage that the light distribution becomes darker due to non-uniformity exceeding the uniformity of the illuminance. can't

그리고, 도 4와 같이, LED(210)로부터 발생된 열은 배광가이드(300) 자체가 열전도효율이 매우 높은 알루미늄으로 제조되어 있기 때문에 열전달이 잘되며, 특히 방열구멍(320)을 통해 외부공기와 쉽고 빠르게 접촉하면서 방열, 냉각되기 때문에 모듈의 장수명화도 달성하게 된다.And, as shown in FIG. 4 , the heat generated from the LED 210 is well heat-transferred because the light distribution guide 300 itself is made of aluminum having a very high heat conduction efficiency. Longer lifespan of the module is also achieved because heat is dissipated and cooled by contacting easily and quickly.

즉, 본 발명은 기존에는 얻을 수 없었던 배광성과 방열성 양자를 모두 향상시키는 효과가 있다.That is, the present invention has an effect of improving both light distribution and heat dissipation properties that were not previously obtained.

이를 더욱 가속화시킬 수 있도록 상기 골(340)의 중심에는 상기 방열구멍(320)과 연통되는 미세구멍이 더 형성될 수 있다.In order to further accelerate this, a fine hole communicating with the heat dissipation hole 320 may be further formed in the center of the valley 340 .

따라서, 모듈홈(110)을 다수개 형성하되, 다수의 갯수로 형성하여 배광가이드(300)를 대칭되게 배치해야 하며, 배광가이드(300)의 높이차를 점진적으로 다르게 한 것 다수개를 연속배치하게 되면 보다 자유로운 배광상태를 구현할 수 있게 된다.Therefore, a plurality of module grooves 110 are formed, but the light distribution guide 300 must be symmetrically arranged by forming a plurality of the number, and a plurality of the light distribution guides 300 with different height differences are sequentially arranged. By doing so, a more free light distribution state can be realized.

이러한 구성으로 이루어진 본 발명은 다음과 같은 작동관계를 갖는다.The present invention having such a configuration has the following operating relationship.

예컨대, 도 5의 예시와 같이 배광가이드(300)의 제1높이(H1) 반대쪽으로 빛의 반사, 분산이 이루어지기 때문에 제1배광선(B1)과 같이 도로노면에서의 배광폭이 제1배광폭(BW1)과 같이 일측으로 넓어진다.For example, as in the example of FIG. 5 , since light is reflected and dispersed opposite to the first height H1 of the light distribution guide 300, the light distribution width on the road surface like the first light distribution line B1 is the first light distribution width. It is widened to one side as in (BW1).

이때, 바닥에서의 조도는 제1조도(IL1)를 이룬다.At this time, the illuminance on the floor constitutes the first illuminance IL1.

또한, 도 6의 예시와 같이 배광가이드(300)의 제1높이(H1)가 도 5와 반대방향으로 배치하면 제2배광선(B2)과 같이 도로노면에서의 배광폭이 제2배광폭(BW2)와 같이 타측으로 넓어진다.In addition, as in the example of FIG. 6 , when the first height H1 of the light distribution guide 300 is arranged in the opposite direction to FIG. 5 , the light distribution width on the road surface is the second light distribution width BW2 like the second light distribution line B2 . ), as in the other side.

이때, 바닥에서의 조도는 제2조도(IL2)를 이룬다.At this time, the illuminance on the floor constitutes the second illuminance IL2.

따라서, 도 5,6에 예시된 2개의 배광가이드(300)를 서로 엇갈려 모두 사용하게 되면 도 7과 같이 배광폭이 현저히 넓어지고, 도로노면에서의 조도도 기본배광을 포함하기 때문에 전체적으로 균일하게 된다.Therefore, when the two light distribution guides 300 illustrated in FIGS. 5 and 6 are used alternately, the light distribution width is remarkably widened as shown in FIG. 7 , and the illuminance on the road surface is uniform as a whole because it includes the basic light distribution. .
