Description

엘이디 평면조명등 {A LED lamp}LED flat lighting lamp {A LED lamp}

본 발명은 LED조명등에 관한 것으로, 특히 LED 빛을 평면상으로 분산을 위하여 또는 은은한 조명등을 제공하기 위하여 사용되는 일정한 면적을 갖는 아크릴판이 온도변화에 수축팽창되어지면서 발생되는 문제점을 해결하기 위한 것이다.The present invention relates to an LED lighting lamp, and in particular, to solve the problem caused by the shrinkage and expansion of the acrylic plate having a certain area used for dispersing the LED light in the plane or to provide a soft lighting.

현재 평면상으로 LED를 사용한 조명등의 빛의 분산이나 은은함 등을 제공하기 위하여 불투명의 아크릴판(일명 도광판)을 사용하고 있고 이러한 도광판의 측단면에 LED가 빛을 주사하면 도강판의 평면으로 빛이 비춰지면서 조명이 이루어지게 되는 것이다.Currently, an opaque acrylic plate (also known as a light guide plate) is used to provide light distribution or softness of a light lamp using an LED on a plane. As it is illuminated, it is illuminated.

따라서 통상 도1에 도시된 바와 같이 도광판(100)이 안착고정되어지기 위한 다각형의 틀(200)은 하나의 바(210)로 이루어져 LED(300)가 장착되어진 기판(310)이 전방으로 빠지지 않게 장착되어지기 위한 홈(220)을 형성하고, 상기 홈(220)의 전방으로는 도광판(100)이 놓여질 수 있는 받침면(230)이 형성되어진 상태에서 상기 받침면(230)에 도광판(100)이 놓여진 상태에서 다각형의 틀(200)로 조립되어짐으로써 도광판의 측단면으로 LED의 빛이 주사되어지면 도광판의 평면으로 빛이 비춰지게 되는 것이다.Therefore, as shown in FIG. 1, the polygonal frame 200 for fixing the LGP 100 is composed of one bar 210 so that the substrate 310 on which the LED 300 is mounted does not fall forward. A light guide plate 100 is formed on the support surface 230 in a state in which a groove 220 is to be mounted and a support surface 230 on which the light guide plate 100 can be placed is formed in front of the groove 220. In this state of being assembled into a polygonal frame 200, when the light of the LED is scanned to the side cross-section of the light guide plate is to shine the light in the plane of the light guide plate.

그러나 이러한 도광판이 대부분 아크릴판으로 이루어지고, 아크릴 판은 열에 의하여 측단면으로 수축팽창되어지고, 이러한 수축팽창이 정도에 따라 다르지만 공식적으로 알려진 바에 의하여 0.3%의 범위에서 수축팽창되어지는 것이기 때문에 이러한 수축팽창으로 인하여 LED와 도광판의 측단면이 밀착되지 못하고 일정거리 이격되어짐으로써 도광판과 LED와의 간격유지에 어려움이 있고, 또한 LED가 가장 우수한 밝기를 갖기 위하여는 아크릴판의 측단면과 밀착되어져야 하나 이러한 수축팽창으로 인하여 LED와 아크릴판의 측단면에서 일정거리 이격되어짐으로 밝기에서 떨어진다는 단점이 있는 것이다.However, such a light guide plate is mainly composed of an acrylic plate, and the acrylic plate is expanded and contracted to the side cross-section by heat, and this shrinkage is due to the expansion and contraction in the range of 0.3% according to the officially known, although this shrinkage expansion varies depending on the degree. Due to the expansion, the side sections of the LED and the LGP are not in close contact with each other and are separated from each other by a certain distance, which makes it difficult to maintain the gap between the LGP and the LED. Also, in order to have the best brightness, the LEDs must be in close contact with the sides of the acrylic plates. Due to shrinkage expansion, there is a disadvantage in that the brightness is lowered by being separated by a certain distance from the side surfaces of the LED and the acrylic plate.

따라서 대부분의 LED조명은 촘촘한 간격으로 다량의 LED를 사용함으로써 조명등으로써의 밝기는 어느정도 보완되었으나 LED에서 발생되는 열로 인한 안전성을 확보하지 못함으로써 실질적으로 사용치 못하게 되는 문제가 있는 것이고, 불필요한 에너지의 낭비는 물론 원가가 상승되어지는 문제점이 있는 것이었다.Therefore, most LED lights have a problem that the brightness of a lamp is compensated to some extent by using a large amount of LEDs at close intervals, but it is practically impossible to use because it does not secure safety due to heat generated from the LED, and wastes unnecessary energy. Of course, there was a problem of rising costs.

따라서 본 발명은 이러한 문제점을 해결하기 위하여 LED와 도광판의 측단면이 서로 밀착된 상태를 유지토록 하면서도 수축팽창시에도 후레임이나 도광판의 손상이 발생되지 않토록 한 것이다.Therefore, in order to solve this problem, the present invention maintains the side surfaces of the LED and the light guide plate in close contact with each other, and does not cause any damage to the frame or the light guide plate even during shrinkage and expansion.

이를 위하여 본 발명은 다각형의 틀을 LED가 장착된 내측후레임과 외측후레임으로 구분하고, 상기 내측후레임이 스프링의 탄성력에 의하여 작동토록 함으로써 LED가 도광판의 측단면과 항상 밀착된 상태를 유지토록 한 것이다.To this end, the present invention divides the polygonal frame into an inner frame and an outer frame in which the LED is mounted, and the inner frame is operated by the elastic force of the spring so that the LED is always in close contact with the side surface of the light guide plate. .

따라서 LED가 아크릴판의 측단면에 밀착되어짐으로써 최소의 LED로 조명등의 원하는 밝기를 얻을 수 있음은 물론 LED를 적게 사용함으로써 원가를 절감토록 함은 물론 조립이 용이토록 함은 물론 열에 의한 안전성도 확보하게 되는 것이다.Therefore, because the LED is in close contact with the side surface of the acrylic plate, it is possible to obtain the desired brightness of the lighting lamp with the minimum LED, and to reduce the cost by using fewer LEDs, to facilitate the assembly, and to ensure thermal safety. Will be done.

이하 첨부도면에 의거 본 발명을 상세히 설명하면 다음과 같다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도2에 도시된 바와 같이 본 발명의 구조는 다각형의 틀(10)을 구성하는 외측후레임(11)의 좌우 또는 전후의 내측에 위치되는 내측후레임(12)이 스프링(20)에 의하여 다각형의 틀(10)의 내측으로 밀려난 상태에서 도광판(30)이 내측후레임(12)을 외측으로 밀어 내면서 탄력지지되게 장착되어 도광판(30)의 측단면이 내측후레임(12)에 장착된 LED(40)와 긴밀하게 밀착된 상태를 유지토록 하는 구성이다.As shown in FIG. 2, the structure of the present invention is that the inner frame 12 located in the left and right or front and rear of the outer frame 11 constituting the frame 10 of the polygon is formed by the spring 20. The light guide plate 30 is mounted to be elastically supported while the inner light guide plate 30 is pushed outward while being pushed into the inside of the 10 so that the side surface of the light guide plate 30 is mounted to the inner frame 12. It is a configuration to keep in close contact with.

이때 내측후레임(12)은 통상 도광판(30)의 좌우 측단면이나 전후 측단면에 위치되어짐으로 틀의 형태로 조립되어지는 것이 아니고 바의 형태로 이루어져 LED(40)가 기판(41)에 장착된 상태에서 기판(41)이 양면테이프(42)로 고정토록 되거나 또는 내측후레임(12)에 별도의 끼임홈을 형성토록 한 후 끼임에 의하여 고정토록 할 수 있는 것이다.At this time, the inner frame 12 is usually located on the left and right side cross-sections and front and rear side cross-sections of the light guide plate 30, and thus is not assembled in the form of a frame. In this state, the substrate 41 may be fixed by the double-sided tape 42 or by being clamped after forming a separate clamping groove in the inner frame 12.

그러나 이러한 고정이 본 발명의 목적을 변화시키는 것이 아니다.However, this fixation does not change the object of the present invention.

이때 내측후레임(12)이 다각형 틀의 내측에서 탄력작동될 경우에 정위치에서 탄력작동되기 위하여 외측후레임(11)에는 슬라이드홈(13)을 형성하고 이에 끼워지 는 내측후레임(12)에는 축(12a)을 형성토록 하여 전후진이 정확하게 이루어지도록 하고, 축(12a)의 직후방으로는 직각면(12b)을 형성하여 LED(40)가 장착된 기판(41)이 양면테이프(42)에 의하여 고정토록 하고, 이러한 기판(41)의 고정작업을 용이토록 하기 위하여 그 전방으로는 끼임홈(12c)을 형성토록 하며 그 전방으로는 도광판(30)이 놓여질 수 있도록 받침턱(12d)을 형성하고, 그 하측면으로는 슬라이드면(12e)을 구비토록 하는 것이다.In this case, when the inner frame 12 is elastically operated in the inner side of the polygonal frame, the outer frame 11 forms a slide groove 13 in the outer frame 11 so as to be elastically operated at the correct position. 12a) is formed so that forward and backward movements are made accurately, and a right angled surface 12b is formed immediately after the axis 12a, so that the substrate 41 on which the LED 40 is mounted is fixed by the double-sided tape 42. In order to facilitate the fixing operation of the substrate 41, a front recess 12c is formed in the front thereof, and a support step 12d is formed in the front so that the light guide plate 30 can be placed thereon. The lower surface is provided with the slide surface 12e.

또한 이러한 슬라이드면(12e)이 슬라이드되도록 외측후레임(11)에도 슬라이드면(17)을 형성하고 이때 슬라이드면(17)은 직각으로 절곡된 내측후레임(12)의 슬라이드면(12e)이 슬라이드될 수 있는 공간확보를 위하여 절곡된 상태에서 이루어지는 것이고, 상기 슬라이드면(17)이 끝나는 부분에는 절곡면(14)에 의한 방열판(16)이 형성되어짐으로써 LED(40)에서 발열되어지는 열을 방열토록 하는 것이다.In addition, a slide surface 17 is also formed on the outer frame 11 so that the slide surface 12e slides. At this time, the slide surface 12e of the inner frame 12 bent at a right angle may slide. It is made in a bent state to secure the space, the heat sink 16 by the bent surface 14 is formed in the end portion of the slide surface 17 to dissipate heat generated in the LED 40 will be.

또한 이 상태에서 도광판의 후방으로는 빛의 손실을 방지하면서 도광판의 보호를 위한 반사판(50)이 장착되어지는 것이고, 이러한 반사판(50)의 고정을 위하여 절곡면(14)의 상면에는 턱(을 형성한 후 상기 턱에 의하여 반사판이 밀려나지 않토록 고정토록 한 것이다.In addition, in this state, the reflector plate 50 for protecting the light guide plate is mounted to the rear of the light guide plate while preventing light loss, and in order to fix the reflector plate 50, the upper surface of the bent surface 14 has a jaw ( After forming it is to be fixed so that the reflector is not pushed by the jaw.

또한 상기 내측후레임이 스프링(20)에 의하여 탄력지지될 경우에 도광판의 수축팽창에 따른 유동거리를 감안하여 스프링은 공간(21)에 위치되어지는 것이다.In addition, when the inner frame is elastically supported by the spring 20, the spring is positioned in the space 21 in consideration of the flow distance due to the expansion and contraction of the light guide plate.

또한 외측후레임(11)을 내측후레임(12)과 조립의 용이성을 제공하기 위하여 커버후레임(11a)과 덮개후레임(11b)으로 구분토록 하고, 이때 커버후레임과 덮개후레임의 고정을 위하여는 덮개후레임(11b)에는 커버후레림의 내입홈에 내입되어지는 보강살을 형성하여 내이토록 함으로써 외면이 돌출됨이 없이 매끄러움을 유지하게 되는 것이고, 그 상태에서 고정을 위하여 보강살을 관통하여 고정결합구로 조임토록 함으로써 고정이 되는 것이다.이때 고정결합구는 너트에 의한 고정결합구의 맞물림으로 너트의 빠짐이 방지되면서 고정토록 되는 것이다.In addition, the outer frame 11 is divided into a cover frame 11a and a cover frame 11b to provide ease of assembly with the inner frame 12. In this case, the cover frame and the cover frame are fixed to fix the cover frame ( 11b) is to maintain the smoothness without protruding the outer surface by forming a reinforcement to be indented into the inlet groove of the cover frame, so that the outer surface is not protruded, and tightened with a fastening fastener through the reinforcement for fixing in that state. In this case, the fixed coupler is fixed while preventing the nut from being pulled out by engaging the fixed coupler by the nut.

그러나 이러한 고정수단이 본 발명의 목적을 변화시키는 것이 아니다.However, such fastening means do not change the object of the present invention.

따라서 도광판이 항상 내측후레임의 LED와 밀착되어져 있기 때문에 빛의 밝기를 우수하게 하는 것이고, 그 상태에서 수축팽창될 경우에 스프링의 탄성력에 의하여 스프링이 공간에서 작동되어짐으로서 종래의 문제점을 해소하게 되는 것이다.Therefore, since the light guide plate is always in close contact with the LED of the inner frame, the brightness of the light is excellent, and when it is contracted and expanded in that state, the spring is operated in the space by the elastic force of the spring to solve the conventional problem. .
