발광효율이 우수한 엘이디램프{A LEDlamp with excellent luminous efficiency}LED lamp with excellent luminous efficiency

본 발명은 발광효율이 우수한 엘이디램프에 관한 것으로, 인도와 차도사이에 설치되는 엘이디램프의 반사판갓과 커버를 일정한 경사각으로 형성하여 엘이디램프에서 발산되는 빛이 반사판갓과 커버를 통해 다양한 각도로 고르게 반사되도록 하여, 차도방향으로 빛이 선명하면서도 골고루 퍼지도록 함으로써, 야간에 운전자들이 시야를 용이하게 확보할 수 있도록 하고, 반사판갓의 상, 하, 측판의 경사각을 각각 다르게 하여 사용자가 원하는 위치에 정확하게 불빛을 비출 수 있도록 한 발광효율이 우수한 엘이디램프에 관한 것이다.The present invention relates to an LED lamp having excellent luminous efficiency. The reflector lampshade and the cover of the LED lamp installed between the sidewalk and the roadway are formed at a predetermined inclination angle so that the light emitted from the LED lamp is evenly distributed through the reflector plate and the cover at various angles. By reflecting, the light is spread evenly and evenly in the direction of the roadway, so that drivers can easily secure the vision at night, and the angle of inclination of the upper, lower, and side plates of the reflector plate is changed differently to exactly the position desired by the user. The present invention relates to an LED lamp having excellent luminous efficiency that enables light to shine.

일반적으로 사용되는 엘이디램프는 특허등록번호 제10 - 921633호와 같이 개별적으로 위치되는 엘이디의 갯 수에 따라 해당 각각의 엘이디마다 개별 리플렉터를 설치하여 상기 개별 리플렉터의 각도를 조정하여 엘이디에서 발산되는 빛이 골고루 퍼지도록 사용하였다.Generally used LED lamps are provided with individual reflectors for each LED according to the number of individually positioned LEDs, such as Patent Registration Nos. 10-921633, and the light emitted from the LEDs is adjusted by adjusting the angle of the individual reflectors. This was used to spread evenly.

그리고, 특허등록번호 제10 - 916113호와 같이 램프의 조사각을 달리하여 불빛이 골고루 퍼지도록 사용하였다.And, as in Patent Registration No. 10-916113, by varying the irradiation angle of the lamp was used to spread the light evenly.

덧붙여, 특허등록번호 제10 - 740659호와 같이 다수개의 엘이디를 덮을 수 있는 렌즈와 렌즈커버의 내부각도를 조절하여 엘이디에서 발산되는 빛이 렌즈와 렌즈커버를 통해 일정하게 굴절되도록 하면서 빛이 골고루 퍼지도록 사용하였다.In addition, as shown in Patent Registration No. 10-740659, by adjusting the inner angle of the lens and the lens cover that can cover a plurality of LEDs, the light emitted from the LED is uniformly refracted through the lens and the lens cover, and the light is spread evenly. It was used to.

아울러, 엘이디의 후면에 반구형태의 반사판을 셜치하여 상기 반사판에 의해 엘이디의 불빛이 일정하게 반사되도록 사용하였다.In addition, a hemispherical reflector plate was placed on the back of the LED so that the light of the LED was constantly reflected by the reflector.

하지만, 상기와 같이 엘이디램프에서 발산되는 빛을 골고루 퍼지게 하기 위해서 다수개의 엘이디램프마다 별도의 다수개의 반사판을 제작하여야 했기 때문에, 제작공정의 증가와 제작비용이 증가되며, 사용자가 일일이 모든 반사판의 각도를 조절해야 하는 불편한 문제점이 있었다.However, in order to spread the light emitted from the LED lamps evenly, as described above, a plurality of separate reflectors must be manufactured for each of the plurality of LED lamps, thus increasing the manufacturing process and manufacturing cost, and the user can change the angle of all the reflecting plates. There was an uncomfortable problem to adjust.

그리고, 다수개의 엘이디램프의 조사각을 일일이 지정해서 설치해야 함으로써, 모든 엘이디램프의 조사각을 조정하기 불편한 문제점이 있었다.In addition, since the irradiation angles of a plurality of LED lamps must be specified and installed, there is a problem that it is inconvenient to adjust the irradiation angles of all the LED lamps.

또한, 모든 엘이디램프마다 각도가 개별적으로 형성된 렌즈나 렌즈커버를 별도로 제작하여 엘이디램프마다 별도로 지정해야 하는 불편함이 있었다.In addition, by separately manufacturing a lens or a lens cover formed with an angle for every LED lamp, there was an inconvenience to specify separately for each LED lamp.

아울러, 엘이디램프의 후면에 설치되는 반사판을 일정한 경사각으로 형성된 반구형태를 형성하게 되면, 엘이디램프에서 발산되는 빛 중에 반사되지 않는 부분이 발생하면서 빛이 비추지 않는 부분이 발생하는 문제점이 있었다.In addition, when forming a hemispherical shape formed with a predetermined inclination angle of the reflecting plate installed on the rear of the LED lamp, there is a problem in that the non-reflective portion of the light emitted from the LED lamp occurs while the light does not shine.

상기와 같은 구성을 가진 본 발명의 바람직한 실시 예에 따른 작용을 살펴보면 다음과 같다.Looking at the operation according to a preferred embodiment of the present invention having the configuration as described above are as follows.

우선, 상기 엘이디램프(11)를 방열판(12)에 결합한 후, 고정판(10)을 반사판갓(20)에 결합하도록 한다.First, the LED lamp 11 is coupled to the heat sink 12, and then the fixing plate 10 is coupled to the reflector plate shade 20.

그런 후, 상기 고정판(10), 반사판갓(20), 덮개(30)가 결합된 발광효율이 우수한 엘이디램프(100)를 도로에 설치된 지주(도면에 미도시)에 설치하도록 한다.Then, the fixing plate 10, the reflecting plate shade 20, the cover 30 is combined with the LED lamp 100 having excellent luminous efficiency to be installed on the post (not shown) installed on the road.

상기 발광효율이 우수한 엘이디램프(100)를 지주에 결합할 때, 전기적인 결합이나 기계적인 결합관계와 발광효율이 우수한 엘이디램프(100)에 형성되는 전기장치(도면에 미도시) 등을 비롯하여 일반적으로 가로등(도면에 미도시)을 설치하는 것과 유사하여 자세한 설명은 생략하도록 한다.When the LED lamp 100 having excellent luminous efficiency is coupled to a post, an electrical device (not shown) formed in the LED lamp 100 having excellent luminous efficiency and electrical coupling or mechanical coupling relationship is generally used. As similar to installing a street light (not shown in the drawing), detailed description thereof will be omitted.

여기서, 상기 반사판갓(20)의 상판(21)이나 하판(22) 중에서 고정판(10)과의 기울어진 경사각이 큰 방향을 차도방향으로 향하도록 하여 가로등 지주에 설치하도록 한다.Here, the inclined inclination angle with the fixing plate 10 of the upper plate 21 or the lower plate 22 of the reflecting plate shade 20 is directed toward the roadway direction so as to be installed on the street lamp post.

이처럼, 상판(21)이나 하판(22) 중에서 경사각이 큰 방향을 차도로 향하도록 한 이유는 상기 반사판갓(20)의 상판(21), 하판(22), 측판(23)의 제1, 2, 3경사각(θ1, θ2, θ3)에 따라 엘이디램프(11)에서 발산되는 빛의 반사각이 변경되는데, 차도와 인도의 경계에 설치되는 가로등의 불빛을 차도방향으로 일정한 지점에 넓게 비추도록 하기 위해 반사각이 상대적으로 큰 부분을 차도방향으로 향하도록 하기 위한 것이다.As such, the reason why the inclination angle of the upper plate 21 or the lower plate 22 is directed toward the road is the first and second of the upper plate 21, the lower plate 22, and the side plate 23 of the reflecting plate shade 20. The reflection angle of the light emitted from the LED lamp 11 is changed according to the three inclination angles θ1, θ2, and θ3, so that the lights of the street lamps installed at the boundary between the roadway and the sidewalk are widely illuminated at a predetermined point in the driveway direction. This is to direct the relatively large portion of the reflection angle toward the roadway direction.

한편, 상기 엘이디램프(11)에서 빛이 상, 하, 측판(21, 22), 23)으로 발산되게 되면, 상기 상, 하, 측판(21, 22, 23)에 부딪히게 되면서 빛이 반사되게 된다.On the other hand, when the light is emitted from the LED lamp 11 to the upper, lower, side plates (21, 22, 23), the light hits the upper, lower, side plates (21, 22, 23) to reflect the light do.

그러면, 상, 하, 측판(21, 22, 23)의 제1, 2, 3경사각(θ1, θ2, θ3)에 의해 상, 하, 측판(21, 22, 23)에서 반사된 빛이 도로의 일정한 지역에 발산되게 되는데 이때, 상, 하 측판(21, 22, 23)은 곡률(r)지게 형성되어 있어, 상, 하, 측판(21, 22, 23)에 의해 반사된 빛이 골고루 퍼지게 된다.Then, the light reflected from the upper, lower, and side plates 21, 22, and 23 by the first, second, and third inclination angles θ1, θ2, and θ3 of the upper, lower, and side plates 21, 22, and 23 The upper and lower side plates 21, 22, and 23 are formed to have a curvature r, so that the light reflected by the upper, lower, and side plates 21, 22, and 23 is spread evenly. .

덧붙여, 상기 제1, 2, 3경사각(θ1, θ2, θ3)을 동일하게 형성하여 엘이디램프(11)에서 발산되는 빛을 골고루 퍼지게 할 수도 있지만, 제1, 2, 3경사각(θ1, θ2, θ3)을 각각 다르게 형성하여 엘이디램프(11)에서 발산되는 빛을 일정한 지점에 보다 넓은 지역으로 퍼지도록 하며, 상, 하, 측판(21, 22, 23)을 곡률(r)지게 형성하여 상, 하, 측판(21, 22, 23)에서 반사되는 빛이 한방향으로만 겹쳐지거나 빛이 도달하지 않는 지역 없이 골고루 퍼지게 되는 것이다.In addition, the first, second, and third inclination angles θ1, θ2, and θ3 may be formed equally so as to spread the light emitted from the LED lamp 11 evenly, but the first, second, and third inclination angles θ1, θ2, θ3) is formed differently so that the light emitted from the LED lamp 11 is spread to a wider area at a predetermined point, and the upper, lower, and side plates 21, 22, and 23 are formed to have a curvature r. Lower, the light reflected from the side plates (21, 22, 23) is to be spread evenly without overlapping only one direction or the area does not reach the light.

여기서, 상기 엘이디램프(11)의 불빛은 보통 120°의 간격으로 발산되게 되는데, 커버(20)의 중간판(31)이 위치된 정면으로 발산되는 빛은 중간판(31)에 부딪히게 되어 엘이디램프(11)에서 발산되는 빛 중에서 중간판(31)이 형성된 위치는 빛에 그림자가 발생할 수도 있으나, 상기 중간판(31)은 일정한 제4경사각(θ4)으로 형성되어 있어, 중간판(31)의 경사진 양측면에 빛이 부딪히면서 상, 하, 측판(21, 22, 23)으로 반사되게 된다.Here, the light of the LED lamp 11 is usually emitted at intervals of 120 °, the light emitted from the front surface where the middle plate 31 of the cover 20 is located hits the middle plate 31 LED Where the intermediate plate 31 is formed of the light emitted from the lamp 11, the shadow may occur in the light, the intermediate plate 31 is formed with a constant fourth inclination angle (θ4), the intermediate plate 31 The light hits both sides of the inclined side of the upper, lower, and is reflected by the side plates (21, 22, 23).

그러면, 상기 상, 하, 측판(21, 22, 23)에 부딪히게 된 빛이 외부로 발산되게 되면서 상, 하, 측판(21, 22, 23)의 내측의 곡률(r)반경에 의해 다양한 각도로 빛이 반사되면서 중간판(31)이 위치된 정면으로도 빛이 반사되어 빛이 비추지 않는 지역 없이 빛이 골고루 퍼지게 되는 것이다.Then, the light hitting the upper, lower, side plates 21, 22, 23 is diverted to the outside, and various angles are caused by the radius of curvature r of the inner side of the upper, lower, side plates 21, 22, 23. As the light is reflected, the light is reflected from the front surface where the intermediate plate 31 is located so that the light is spread evenly without a region where the light does not shine.

또한, 상기 커버(30)의 테두리(32)는 중간판(31)에서 제5경사각(θ5)으로 경사지게 형성되어 있어, 엘이디램프(11)의 정면방향뿐만 아니라 엘이디램프(11)의 정면에서 제5경사각(θ5)만큼 측면방향으로도 퍼지게 되기 때문에, 보다 넓은 방향으로 엘이디램프(11)의 빛이 분산되게 되는 것이다.In addition, the edge 32 of the cover 30 is formed to be inclined at the fifth inclination angle θ5 from the intermediate plate 31, so that not only the front direction of the LED lamp 11 but also the front of the LED lamp 11 is formed. Since it also spreads in the lateral direction by five inclination angles θ5, the light of the LED lamp 11 is dispersed in a wider direction.

이처럼, 상기 반사판갓(20)의 상, 하, 측판(21, 22, 23)의 제1, 2 3경사각(θ1, θ2, θ3)을 각각 다르게 형성하여, 엘이디램프(11)에서 발산되는 빛을 넓은 지역으로 분산시키면서 일정한 지역으로 집중하도록 하여 빛의 발광효율을 높임과 동시에, 엘이디램프(11)의 전방에 설치된 중간판(31)을 제4경사각(θ4)으로 경사지 게 하여 중간판(31)으로 발산되는 빛을 상, 하, 측판(21, 22, 23)으로 다시 반사시켜 상기 상, 하, 측판(21, 22, 23)에 의해 다시 외부로 넓게 퍼지게 하여 중간판(31)에 의한 빛이 비추지 않는 곳을 제거하며, 상, 하, 측판(21, 22, 23)에 형성된 곡률(R)을 중간판(31)과 테두리(32)의 길이의 합(h)보다 넓은 곡률(r)반경으로 제작하여 상, 하, 측판(21, 22, 23)에서 반사되는 빛이 사각없이 골고루 퍼지도록 할 수 있게 되는 것이다.As such, the first, second, and third inclination angles θ1, θ2, and θ3 of the upper, lower, and side plates 21, 22, and 23 of the reflecting plate shade 20 are formed differently, and the light emitted from the LED lamp 11 is different. The light emitting efficiency of light by dispersing the light into a wide area and increasing the light emitting efficiency of the light, and inclining the middle plate 31 installed in front of the LED lamp 11 to the fourth inclination angle θ4. By reflecting the light emitted by the back to the upper, lower, side plates (21, 22, 23) to spread out again by the upper, lower, side plates (21, 22, 23) to the outside by the intermediate plate (31) The curvature R formed on the top, bottom, and side plates 21, 22, and 23 is removed, and the curvature wider than the sum (h) of the lengths of the middle plate 31 and the edge 32 is removed. r) It is to be made to the radius so that the light reflected from the upper, lower, side plates (21, 22, 23) can be spread evenly without a square.

여기서, 상기 상, 하, 측판(21, 22, 23)에 형성된 곡률(R)을 중간판(31)과 테두리(32)의 길이의 합(h)보다 작게 형성할 경우, 엘이디램프(11)에서 발산되는 빛이 한 지점으로만 집중될 수 있기 때문에, 이를 방지하기 위해 상, 하, 측판(21, 22, 23)에 형성된 곡률(R)을 중간판(31)과 테두리(32)의 길이의 합(h)보다 크게 형성하는 것이다.Herein, when the curvature R formed on the upper, lower, and side plates 21, 22, and 23 is smaller than the sum h of the lengths of the intermediate plate 31 and the edge 32, the LED lamp 11 Since the light emitted from the light source can be concentrated only at one point, the curvature R formed on the upper, lower, and side plates 21, 22, and 23 to prevent the length of the intermediate plate 31 and the edge 32 is prevented. Is larger than the sum (h).

그리고, 상기 상, 하, 측판(21, 22, 23)의 제1, 2, 3경사각(θ1, θ2, θ3)과 제5경사(θ5)을 55 ~ 75°, 60 ~ 80°, 45 ~ 65°, 5 ~ 25°의 각도로 형성함으로써, 엘이디램프(11)에서 발산되는 빛이 상, 하, 측판(21, 22, 23)에 의해 반사될 때, 반사각을 최대로 활용하여 빛을 넓은 지역으로 분산시키면서 집중시킬 수 있게 되는 것이다.In addition, the first, second and third inclination angles θ1, θ2 and θ3 and the fifth inclination θ5 of the upper, lower and side plates 21, 22, and 23 are 55 to 75 degrees, 60 to 80 degrees, and 45 to 45 degrees. By forming at an angle of 65 °, 5 to 25 °, when the light emitted from the LED lamp 11 is reflected by the upper, lower, and side plates 21, 22, and 23, the light is maximized by utilizing the maximum reflection angle. It will be possible to concentrate while dispersing into regions.

덧붙여, 상기 엘이디램프(11)에서 발산되는 빛이 중간판(31)에 의해 흑점이 생기데 되는데 중간판(31)의 제4경사각(θ4)을 45 ~ 65°로 형성하여 엘이디램프(11)에서 발산되는 빛이 중간판(31)에서 반사되어 상, 하, 측판(21, 22, 23)으로 다시 반사되도록하고 상기 상, 하, 측판(21, 22, 23)에서 외부로 반사되도록 하여, 엘이디램프의 반사효율을 높이면서 중간판(31)에 의한 흑점을 보완하게 되는 것이다.In addition, the light emitted from the LED lamp 11 causes black spots due to the intermediate plate 31. The fourth inclination angle θ4 of the intermediate plate 31 is formed at 45 to 65 ° so that the LED lamp 11 The light emitted from the reflected by the intermediate plate 31 is reflected back and down to the upper, lower, side plates (21, 22, 23), and reflected from the upper, lower, side plates (21, 22, 23) to the outside, While increasing the reflection efficiency of the LED lamp is to compensate for the black spots by the intermediate plate (31).

여기서, 상기 중간판(31)을 형성하지 않고 엘이디램프(11)의 빛을 직접 중앙으로 발산시킬 수도 있지만, 엘이디램프(11)의 발광효율을 높이기 위해 엘이디램프(11)의 전면에 중간판(31)을 형성하여 상기 중간판(31)을 통해 엘이디램프(11)의 빛이 반사되도록 하여, 엘이디램프(11)의 불빛을 효율적으로 사용할 수 있게 되는 것이다.Here, the light of the LED lamp 11 may be directly emitted to the center without forming the intermediate plate 31, but in order to increase the luminous efficiency of the LED lamp 11, the intermediate plate () may be disposed on the front surface of the LED lamp 11. 31 is formed to reflect the light of the LED lamp 11 through the intermediate plate 31, so that the light of the LED lamp 11 can be used efficiently.

또한, 상기 커버(30)의 테두리(32)를 중간판(31)에서 일정한 제5경사각(θ5)으로 경사지게 함으로써, 엘이디램프(11)에 발산되는 빛을 보다 넓게 퍼지도록 하여 엘이디램프(11)에서 발산되는 빛을 일정한 지역에 넓게 골고루 퍼지도록 하면서 빛을 집중시켜 야간에 도로를 주행하는 운전자의 시야를 넓게 확보할 수 있게 한다.In addition, by inclining the edge 32 of the cover 30 to a constant fifth inclination angle θ5 in the intermediate plate 31, the LED lamp 11 to spread the light emitted by the LED lamp 11 wider than the LED lamp 11 By spreading the light emitted from a wide range evenly in a certain area to concentrate the light to ensure a wider view of the driver driving on the road at night.
