Description

반사판을 가지는 ＬＥＤ 램프 등 기구{lighting instruments have reflecting plate}Lighting instruments have reflecting plate

본 발명은 LED 램프를 이용한 등 기구에 관한 것으로서, 더욱 상세하게는 중앙에 아크릴 도광판을 사용하고 상기 도광판의 양측으로 LED 램프를 구비한 등 기구에 적을 수의 LED 램프로도 빛의 조도를 높일 수 있도록 LED 램프 기판에 반사판을 구비한 등 기구에 관한 것이다.The present invention relates to a light fixture using an LED lamp, and more particularly, to increase the illuminance of the light even with a number of LED lamps using an acrylic light guide plate in the center and an LED lamp on both sides of the light guide plate. The invention relates to a luminaire having a reflector plate on the LED lamp substrate.

일반적으로 등 기구는 형광등이나 백열등과 같이 어두운 곳을 밝히기 위하여 사용하는 것으로서, 특히 실내의 천장에 설치되어 실내를 밝히기 위하여 사용되어 왔었다. 따라서, 이러한 등 기구는 이미 알려진 바와 같이 형광램프나 백열 램프를 광원으로 하여 등 기구에 결합한 후 전원을 인가하면 형광램프 또는 백열 램프가 발광함으로 실내를 밝혀 왔었다.In general, the lighting fixtures are used to illuminate a dark place such as a fluorescent lamp or an incandescent lamp, and have been used to illuminate an interior, especially when installed on the ceiling of a room. Therefore, such a lamp has been known as a fluorescent lamp or an incandescent lamp as a light source, and as a known light source, after the power is applied, the fluorescent lamp or the incandescent lamp emits light.

그러나, 상기와 같은 일반적인 등 기구는 광원인 램프의 수명이 한정되어 있어 램프를 교체하여야 하는 문제점이 발생하였고 등 구를 설치하기 위해서는 일정한 공간을 필요로 하기 때문에 최근에는 빛을 난반사하는 아크릴 도광판을 이용한 등 기구를 사용하고 있다.However, the above-described general lighting fixtures have a problem in that the lamps, which are light sources, have a limited life and have to be replaced. In recent years, acrylic light guide plates that diffusely reflect light have been used. I use a lamp.

따라서, 상기와 같은 아크릴 도광판을 이용한 등 기구는 광원으로서 LED 램프를 사용함으로 등 기구를 슬림화시키고 광원인 LED 램프의 수명이 반 영구적인 장점을 가지며, 광원인 LED 램프를 다양한 색상으로 발광하게 함으로 실내 인테리어 조명과 같은 용도로 사용하기 적합한 장점을 가진다.Therefore, the light fixture using the acrylic light guide plate as described above has the advantage of slimming the light fixture by using the LED lamp as a light source, and has a semi-permanent lifespan of the LED lamp which is the light source. It has the advantage of being suitable for use such as interior lighting.

그러나, 상기와 같은 LED 램프를 이용한 등 기구는 충분한 조도를 얻기 위해서는 많은 수의 LED 램프를 사용하여야 함으로 제품가격이 상승되는 문제점을 가지고 많은 수의 LED 램프를 사용함으로 인하여 많은 전력의 소비를 가져오는 문제점이 발생하였다.However, the luminaire using the above-described LED lamp has to use a large number of LED lamps in order to obtain sufficient illuminance, which leads to a problem that the product price rises and the consumption of a large amount of power due to the use of a large number of LED lamps. A problem occurred.

본 발명은 상기와 같이 종래에 LED 램프를 이용한 등 기구에서 발생하는 문제점을 해결하기 위하여 발명한 것으로서, 도광판을 사이에 두고 서로 마주하는 LED 램프 기판에 반사판을 구비함으로 마주하는 비교적 적은 수의 LED 램프로도 충분한 조도를 얻을 수 있도록 하기 위한 반사판을 가지는 LED 램프 등 기구를 제공하는데 본 발명의 목적이 있는 것이다.The present invention has been invented to solve the problems occurring in a conventional lighting device using an LED lamp as described above, a relatively small number of LED lamps facing by having a reflector on the LED lamp substrate facing each other with a light guide plate therebetween It is an object of the present invention to provide a mechanism such as an LED lamp having a reflecting plate so as to obtain sufficient illuminance.

상기와 같은 목적을 달성하기 위하여 본 발명이 실시하는 해결수단을 실시 예로 설명하면 다음과 같다.In order to achieve the above object, a solution implemented by the present invention will be described as an example.

외부 테두리를 구성하는 본체와;A main body constituting the outer frame;

상기 본체의 내부에 위치하여 빛을 난반사시키는 도광판과;A light guide plate positioned inside the main body to diffusely reflect light;

상기 도광판의 주변으로 본체의 내측에 위치하고 LED 램프를 일정한 간격을 가지게 복수의 수로 고정한 기판과;A substrate which is positioned inside the main body around the light guide plate and fixed to a plurality of LED lamps at regular intervals;

상기 기판의 표면에 마주하는 LED 램프의 빛을 반사시키는 반사판으로 구성한 것이다.It consists of a reflector which reflects the light of the LED lamp facing the surface of the said board | substrate.

이때, 상기 기판에 고정된 LED 램프는 마주하는 기판에 고정된 LED 램프와 서로 엇갈리게 고정되는 것이 바람직하다.At this time, it is preferable that the LED lamp fixed to the substrate is fixedly staggered with the LED lamp fixed to the facing substrate.

그리고, 상기 반사판은 기판의 표면에 부착되고 LED 램프가 위치하는 부위는 LED 램프를 삽입하여 돌출시킬 수 있도록 홀을 형성하는 것이 바람직하며, LED 램프의 높이와 동일 또는 유사한 두께를 가지는 것이 바람직하다.In addition, the reflecting plate is attached to the surface of the substrate and the portion where the LED lamp is located is preferably formed to form a hole so as to protrude by inserting the LED lamp, it is preferable to have the same or similar thickness to the height of the LED lamp.

상기와 같은 해결수단을 가지는 본 발명은 반사판이 마주하는 LED 램프에서 발광된 빛을 반사함으로 종래의 등 기구에 사용된 LED 램프의 수보다 적은 수로 동일한 조도를 얻을 수 있어 제품의 가격을 저렴하게 할 수 있는 장점을 가지고, 비교적 적은 수의 LED 램프를 사용함으로 등 기구의 소비전력을 절감할 수 있는 장점을 가지는 발명이다.According to the present invention having the above-described solutions, the same illuminance can be obtained by reducing the number of LED lamps used in the conventional lighting fixture by reflecting the light emitted from the LED lamps facing the reflector, thereby reducing the price of the product. It is an invention having the advantage that can reduce the power consumption of the fixture by using a relatively small number of LED lamps.

이하, 본 발명의 실시를 위한 구체적인 구성 및 작용을 첨부된 도면과 같은 실시 예를 통해서 상세히 설명하면 다음과 같다. Hereinafter, the specific configuration and operation for the implementation of the present invention will be described in detail with reference to the embodiments as shown in the accompanying drawings.

첨부된 도면 도 1과 같이 실시 예를 통하여 나타난 본 발명의 구성은,The configuration of the present invention shown through the embodiment as shown in Figure 1,

외부 테두리를 구성하는 본체(100)와; A main body 100 constituting an outer frame;

상기 본체(100)의 내부에 위치하여 빛을 난반사시키는 도광판(200)과;A light guide plate 200 positioned inside the main body 100 to diffusely reflect light;

상기 도광판(200)의 주변으로 본체(100)의 내측에 위치하고 LED 램프(310)를 일정한 간격을 가지게 복수의 수로 고정한 기판(300)과;A substrate 300 positioned inside the main body 100 around the light guide plate 200 and fixed to a plurality of numbers of the LED lamps 310 at regular intervals;

상기 기판(300)의 표면에 마주하는 LED 램프(310)의 빛을 반사시키는 반사판(400)으로 구성한 것이다.The reflective plate 400 reflects the light of the LED lamp 310 facing the surface of the substrate 300.

이때, 상기 기판(300)에 고정된 LED 램프(310)는 마주하는 기판(300)에 고정된 LED 램프(310)와 서로 엇갈리게 고정한다.In this case, the LED lamp 310 fixed to the substrate 300 is fixed to the LED lamp 310 fixed to the substrate 300 to face each other.

그리고, 상기 반사판(400)은 기판(300)의 표면에 부착되고 LED 램프(310)가 위치하는 부위에는 LED 램프(310)를 삽입하여 돌출시킬 수 있도록 홀(410)을 형성하며, 반사판(400)이 LED 램프(310)의 높이와 동일 또는 유사한 두께를 가진다.The reflective plate 400 is attached to the surface of the substrate 300 and forms a hole 410 to protrude by inserting the LED lamp 310 in the portion where the LED lamp 310 is located, the reflective plate 400 ) Has the same or similar thickness as the height of the LED lamp 310.

따라서, 전원을 인가하면 기판(300)에 고정된 LED 램프(310)가 발광을 하고 이러한 빛은 도광판(200)을 통하여 난반사 하면서 도광판(200) 전체가 밝아져 실내를 밝히는 것이다. Therefore, when the power is applied, the LED lamp 310 fixed to the substrate 300 emits light, and the light is diffusely reflected through the light guide plate 200 to brighten the entire light guide plate 200 to brighten the room.

이때, 도광판(200)을 사이에 두고 서로 마주하는 기판(300)에 고정된 LED 램프(310)의 빛은 반대편 기판(300)까지 전달되고 이와 같이 전달된 빛은 기판(300)의 표면에 부착된 반사판(400)에 반사되어 다시 도광판(200)을 전달된다.In this case, the light of the LED lamp 310 fixed to the substrate 300 facing each other with the light guide plate 200 therebetween is transmitted to the opposite substrate 300, and the light thus transmitted is attached to the surface of the substrate 300. The light reflecting plate 400 is reflected to the light guide plate 200 again.

따라서, 반사판(400)에 반사되는 빛을 활용함으로 비교적 적은 수의 LED 램프(310)만으로도 충분한 조도를 얻을 수 있는 것이며, 반사판(400)은 LED 램프(310)가 위치하는 부위에는 LED 램프(310)가 삽입되는 홀(410)이 형성되어 있어 기판(300)에서 LED 램프(310)가 고정된 다른 부위 모두를 반사판(400)이 가리고 있어 마주하는 LED 램프(310)의 빛을 반사시킨다.Therefore, by utilizing the light reflected on the reflector plate 400, a sufficient illuminance can be obtained with only a relatively small number of LED lamps 310, and the reflector plate 400 is an LED lamp 310 at a portion where the LED lamp 310 is located. ) Is inserted into the hole 410 so that the reflector 400 covers all other portions of the substrate 300 to which the LED lamp 310 is fixed, thereby reflecting light from the LED lamp 310 facing each other.

그리고, 반사판(400)이 기판(300)에서 돌출된 LED 램프(310)의 높이와 동일한 두께를 가짐으로 반사판(400)이 도광판(200)의 측면에 밀착되어 도광판(200)을 통해서 전달되는 LED 램프(310)의 빛을 효율적으로 반사시킴으로 적은 수의 LED 램프(310)로도 충분한 조도를 얻을 수 있는 것이다.In addition, since the reflector plate 400 has the same thickness as the height of the LED lamp 310 protruding from the substrate 300, the reflector plate 400 is in close contact with the side surface of the light guide plate 200 and is transmitted through the light guide plate 200. By reflecting the light of the lamp 310 efficiently, even a small number of LED lamps 310 can obtain sufficient illuminance.
