본 발명은 백색 발광다이오드를 이용한 조명등에 관한 것으로, 특히 고출력의 백색 발광다이오드를 이용하여 실내 조명으로 사용할 수 있는 조명등에 관한 것이다.The present invention relates to a lamp using a white light emitting diode, and more particularly to a lamp that can be used as indoor lighting using a high power white light emitting diode.

일반적으로, 실내 조명등은 벌브 내부의 필라멘트에 전류를 가하여 발열에 의해 방출되는 빛을 이용하는 백열전구와 수은 증기관 내에 필라멘트에서 방출된 전자와 수은 증기와의 충돌에 의해 빛을 방출하게 되는 형광등이 많이 사용되고 있다. 그러나, 이러한 종래의 실내 조명등은 전력 소모가 크고 조도가 낮은 문제점이 있으며, 수명이 짧은 문제점이 있다.Generally, incandescent lamps which use light emitted by heat by applying electric current to the filament inside the bulb and fluorescent lamps that emit light by collision of electrons and mercury vapor emitted from the filament in the mercury vapor tube are widely used. . However, such a conventional indoor lighting has a problem of high power consumption and low illuminance, and a short lifespan.

최근에는 백색 발광다이오드는 이용하여 조명기구에 이용하고자 하는 시도가 있으며, 이러한 백색 발광다이오드는 전력소모가 낮으면서도 일반 백열전구나 형광등과 비교하여 반영구적으로 사용이 가능한 장점이 있다. Recently, there is an attempt to use a light emitting device using a white light emitting diode, and the white light emitting diode has a low power consumption and can be used semipermanently compared to a general incandescent lamp or a fluorescent lamp.

그러나, 발광다이오드를 조명기구의 광원으로 이용함에 있어, 직접 조명용 광원으로 사용 시에 발광다이오드의 직진성으로 인해 조명기구의 조명갓을 투과하 게 되며, 발광다이오드의 빛이 주변으로 확산되지 못하는 문제점이 있다.However, when using the light emitting diode as a light source of the lighting fixture, when used as a direct light source, the light emitting diode is transmitted through the lamp shade of the lighting fixture due to the straightness of the light emitting diode, there is a problem that the light of the light emitting diode is not diffused to the surroundings. .

즉, 실내용 조명기구에서는 그 기능상 광원의 빛이 주변으로 충분히 확산되어 주변을 밝혀주어야 하나, 고휘도 백색 발광다이오드는 시야각(viewing angle)이 좁아서 광원의 빛이 주변으로 확산되지 못하여 실내용 조명기구에 적용 시에 문제점이 있다.That is, in the indoor lighting fixture, the light of the light source must be sufficiently diffused to illuminate the periphery, but the high brightness white light emitting diode has a narrow viewing angle, so that the light of the light source cannot be diffused to the ambient lighting fixture. There is a problem in the application.

본 발명은 상기의 결점을 해소하기 위한 것으로, 백색 발광다이오드를 이용한 조명등에 있어, 광원의 빛이 주변으로 확산되도록 하여 조명등 바깥으로 균일한 광분포를 얻을 수 있는 백색 발광다이오드를 이용한 조명등을 제공하고자 한다.The present invention is to solve the above-described drawbacks, in the lighting using a white light emitting diode, to provide a light using a white light emitting diode that can obtain a uniform light distribution outside the lighting by allowing the light of the light source to diffuse to the surroundings. do.

이러한 본 발명의 백색 발광다이오드를 이용한 조명등은, 표면에 다수의 돌기가 형성된 반사판과; 상기 반사판에 고정되는 1W 이상의 광출력을 갖는 백색 발광다이오드를 포함하는 광원부와; 상기 광원부를 덮도록 상기 반사판에 고정되는 유백 아크릴 또는 유백 유리 재질이되, 상기 광원부와의 최근거리가 4 ~ 10 ㎝ 범위 내에서 이격되어 위치하는 커버부로 구성되는 것을 특징으로 한다.Such a lamp using a white light emitting diode of the present invention, the reflection plate is formed with a plurality of projections on the surface; A light source unit including a white light emitting diode having a light output of 1 W or more fixed to the reflector; It is made of a milky acrylic or milky glass material fixed to the reflector to cover the light source, characterized in that the recent distance from the light source is composed of a cover part spaced apart in the range of 4 ~ 10 cm.

본 발명의 실시예를 첨부 도면을 참고하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1 및 도 2를 참고하면, 본 발명의 백색 발광다이오드를 이용한 조명등은, 표면에 다수의 돌기(111)가 형성된 반사판(110)과; 상기 반사판(110)에 고정되는 1W 이상의 광출력을 갖는 백색 발광다이오드를 포함하는 광원부(120)와; 상기 광원부(120)를 덮도록 상기 반사판(110)에 고정되는 유백 아크릴 또는 유백 유리 재질이되, 상기 광원부(120)와의 최근거리가 4 ~ 10 ㎝ 범위 내에서 이격되어 위치하는 커버부(130)로 구성되는 것을 특징으로 한다.1 and 2, a lamp using a white light emitting diode of the present invention includes a reflector plate 110 having a plurality of protrusions 111 formed on a surface thereof; A light source unit 120 including a white light emitting diode having a light output of 1 W or more and fixed to the reflective plate 110; Cover portion 130 is made of a milky acrylic or milky glass material fixed to the reflector 110 to cover the light source unit 120, the most recent distance from the light source unit 120 is spaced apart within the 4 ~ 10 cm range Characterized in that consists of.

반사판(110)은 표면에 다수의 돌기(111)가 돌출 형성된 평판 형상이며, 백색 발광다이오드 광원부(120)가 고정된다.The reflecting plate 110 has a flat plate shape with a plurality of protrusions 111 protruding from the surface thereof, and the white light emitting diode light source unit 120 is fixed.

반사판(110)은 커버부(130)에서 반사된 빛을 다시 반사시키게 되며, 표면에 돌출 형성된 돌기(111)에 의해 난반사가 발생한다.The reflecting plate 110 reflects the light reflected from the cover 130 again, and diffuse reflection occurs by the protrusion 111 protruding from the surface.

특히, 본 발명에 있어 반사판(110)은 알루미늄 재질을 사용함으로써, 발광다이오드 광원부의 작동 중에 발생하는 열이 주변으로 신속히 방출되도록 하는 것이 바람직하다.In particular, in the present invention, the reflective plate 110 is preferably made of aluminum so that the heat generated during the operation of the light emitting diode light source unit is quickly discharged to the surroundings.

도 2에는 반사판(110)에 단면이 곡면인 돌기(111)가 형성됨을 도시하고 있으며, 이 돌기(111)는 커버부(130)에서 반사된 빛을 다시 난반사시켜 커버부(130)로 조사되도록 한다.FIG. 2 illustrates that the projection 111 having a curved cross section is formed on the reflector 110, and the projection 111 diffuses the light reflected from the cover 130 back to the cover 130. do.

도 3은 본 발명에 있어 반사판에 형성된 돌기의 다른 예를 보여주는 도면으로, 반사판(110)에는 V 형상의 돌기(112)가 형성될 수가 있다. 이러한 V 형상의 돌기(112)는 반사판(110)으로 조사된 빛이 돌기에 의해 난반사가 이루어진다.3 is a view showing another example of the protrusion formed on the reflecting plate in the present invention, the V-shaped protrusion 112 may be formed on the reflecting plate 110. The V-shaped protrusion 112 is diffusely reflected by the projection of light irradiated to the reflecting plate 110.

본 발명에 있어 반사판에 형성된 돌기는 곡면 형상과 V 형상의 돌기가 조합 된 형태가 이용될 수도 있으며, 빛의 난반사가 이루어질 수 있는 다른 변형된 형태일 수가 있다.In the present invention, the protrusion formed on the reflector may be a combination of a curved shape and a V-shaped protrusion, or may be another modified shape in which diffuse reflection of light may be made.

백색 발광다이오드 광원부(120)는 1W 이상의 광출력을 갖는 최소한 하나 이상의 고출력 백색 발광다이오드와, 이 고출력 백색 발광다이오드를 구동하기 위한 구동회로를 포함한다. 광원부(120)를 구성하는 발광다이오드의 숫자는 조명기구에서 요구되는 조도에 따라서 결정된다. 각각의 백색 발광다이오드는 직접 반사판에 설치된 수도 있으며, 다수의 백색 발광다이오드가 구동회로와 함께 PCB에 부착된 광원 모듈이 반사판에 설치될 수가 있다. The white light emitting diode light source unit 120 includes at least one high power white light emitting diode having a light output of 1 W or more, and a driving circuit for driving the high power white light emitting diode. The number of light emitting diodes constituting the light source unit 120 is determined according to the illuminance required by the luminaire. Each white light emitting diode may be directly installed in a reflector, and a light source module in which a plurality of white light emitting diodes are attached to a PCB together with a driving circuit may be installed in the reflector.

커버부(130)는 투명도가 낮은 유백 아크릴 또는 유백 유리로 제작되며, 백색 발광다이오드 광원부(120)를 감싸면서 반사판(110)에 고정된다. 커버부(130)는 조명등의 형상에 따라서 다양한 형태가 있을 수 있다.The cover part 130 is made of milky acrylic or milky glass having low transparency, and is fixed to the reflector 110 while surrounding the white light emitting diode light source part 120. The cover 130 may have various forms according to the shape of the lamp.

유백 아크릴 또는 유백 유리를 재질로 하는 커버부(130)는 유백색 안료 또는 미립자에 의해 불투명하며, 통상적으로 빛의 투과율이 50 ~ 60 % 정도이다. 따라서 커버부(130) 안쪽 면에서 반사된 빛은 일부만이 직접 커버부(130)를 투과하여 방출되며, 일부는 커버부(130)의 내측 면에서 반사되어 반사판(110)으로 조사된다.The cover 130 made of milky acrylic or milky glass is opaque by milky pigment or fine particles, and typically has a light transmittance of about 50 to 60%. Therefore, only part of the light reflected from the inner surface of the cover part 130 is emitted through the cover part 130 directly, and part of the light is reflected from the inner side of the cover part 130 and irradiated to the reflecting plate 110.

특히, 본 발명에 있어 커버부(130)는 백색 발광다이오드 광원부(120)와의 최근거리가 4 ~ 10㎝ 범위 내에 있는 것이 바람직함이 확인되었다.In particular, in the present invention, it was confirmed that the cover portion 130 preferably has a recent distance with the white light emitting diode light source portion 120 within a range of 4 to 10 cm.

예를 들어, 백색 발광다이오드 광원부(120)와 커버부(130) 사이의 최근거리가 4 ㎝ 이내인 경우에는 커버부의 내측에서 빛이 확산되지 못하고 광원이 외부로 직접 노출(커버부를 통해 광원이 점으로 나타남)됨을 확인하였으며, 이러한 경우에는 커버부(120) 바깥으로 확산된 균일한 광분포를 갖는 조명을 얻을 수 없으며, 따라서 실내용 조명기구로 적합하지가 않다. For example, when the most recent distance between the white light emitting diode light source unit 120 and the cover unit 130 is within 4 cm, light is not diffused inside the cover unit and the light source is directly exposed to the outside. In this case, it is not possible to obtain a light having a uniform light distribution diffused out of the cover portion 120, and thus is not suitable as an indoor lighting fixture.

특히, 1W 이상의 광출력을 갖는 고출력 백색 발광다이오드를 광원으로 사용하는 경우에는, 광원부(120)와 커버부(130) 사이의 최근거리가 4 ㎝ 이내인 경우에 광원이 외부로 직접 노출됨이 확인되었다.In particular, when using a high-output white light emitting diode having a light output of 1W or more as a light source, it was confirmed that the light source is directly exposed to the outside when the recent distance between the light source unit 120 and the cover unit 130 is within 4 cm. .

또한, 백색 발광다이오드 광원부(120)와 커버부(130) 사이의 최근거리가 10 ㎝ 이상 이격되는 경우에는 조도가 현저히 낮아져서 조명기구로써 사용이 적합하지가 않음이 확인되었다.In addition, when the recent distance between the white light emitting diode light source unit 120 and the cover unit 130 is more than 10 cm apart, the illuminance is significantly lowered, it was confirmed that it is not suitable for use as a lighting fixture.

따라서, 본 발명은 1W 이상의 광출력을 갖는 고출력 백색 발광다이오드 광원부(120)와 커버부(130) 사이의 최근거리가 4 ~ 10 ㎝ 범위인 것이 바람직하다.Therefore, in the present invention, it is preferable that the recent distance between the high power white light emitting diode light source unit 120 and the cover unit 130 having a light output of 1 W or more is in the range of 4 to 10 cm.

도 2에는 곡면 형태의 커버부(130)를 보여주고 있으며, 이러한 곡면 형태의 커버부(130)에서는 커버부(130)의 접선 방향으로의 광원부(120)와의 최단거리가 최근거리(D1)가 된다.2 shows a cover portion 130 having a curved shape. In this cover portion 130 having a curved shape, the shortest distance with the light source 120 in the tangential direction of the cover portion 130 is the latest distance D1. do.

광원부(120)와 커버부(130) 사이의 최단거리가 4 ~ 10 ㎝를 유지한다면 전체적인 커버부(130)의 형상은 자유롭게 변형이 가능하다.If the shortest distance between the light source unit 120 and the cover unit 130 maintains 4 ~ 10 cm, the overall shape of the cover unit 130 can be freely deformed.

도 5는 사각 단면 구조를 갖는 커버부(230)를 보여주고 있으며, 이러한 사각 단면 구조의 커버부(230)에서는 광원부(220)와 커버부(230) 사이의 수직 높이가 최근거리(D2)가 된다.5 shows a cover portion 230 having a rectangular cross-sectional structure, in which the vertical height between the light source 220 and the cover portion 230 has a recent distance D2 in the cover portion 230 having a rectangular cross-sectional structure. do.

도 6의 (a) 및 (b)는 단면이 반구 구조를 갖는 커버부(330)를 보여주고 있으 며, 반사판(310)에는 일렬로 배열된 백색 발광다이오드 광원부(320)가 고정되며, 반원통 형상의 커버부(330)가 반사판(310)에 고정된다.6 (a) and 6 (b) show a cover portion 330 having a hemisphere structure in cross section, and the white light-emitting diode light source portions 320 arranged in a line are fixed to the reflector plate 310 and have a semi-cylindrical shape. The cover part 330 of the shape is fixed to the reflecting plate 310.

도 6의 (b)에 도시된 바와 같이, 이러한 반원통 형상의 커버부(330)에서는 커버부(330)의 곡률 반경이 최근거리(D3)가 된다.As shown in FIG. 6B, in the semi-cylindrical cover portion 330, the radius of curvature of the cover portion 330 becomes the most recent distance D3.

도 4는 본 발명의 제1실시예에 따른 백색 발광다이오드를 이용한 조명등의 단면도이다.4 is a cross-sectional view of a lamp using a white light emitting diode according to a first embodiment of the present invention.

도 4에 도시된 바와 같이, 백색 발광다이오드 광원부(120)에서 조사된 빛은 커버부(130)에서 일부만이 투과(A 광로)되며 일부는 커버부(130)의 내측 면에서 반사되어 반사판(110)로 조사되며, 반사판(110)에서 반사된 빛은 확산되어 커버부(130)를 투과(B 광로)하게 된다.As shown in FIG. 4, light emitted from the white light emitting diode light source unit 120 is partially transmitted from the cover unit 130 (A light path), and part of the light is reflected from the inner surface of the cover unit 130 to reflect the plate 110. Irradiated with light) and reflected by the reflector 110 is diffused to transmit the cover portion 130 (B optical path).

즉, 백색 발광다이오드 광원부(120)에서 조사된 빛은 커버부(130)와 반사판(110) 사이에서 반사가 이루어지면서 확산되어 커버부(130) 바깥으로 균일한 광분포를 가지며 방출된다.That is, the light emitted from the white light emitting diode light source unit 120 diffuses while being reflected between the cover unit 130 and the reflector plate 110 and has a uniform light distribution to the outside of the cover unit 130.

한편, 반사판(110)에 돌출 형성된 돌기(111)는 빛을 난반사 시켜 빛의 확산의 돕는 기능을 한다.On the other hand, the protrusion 111 protruding from the reflecting plate 110 diffuses the light to serve to help the diffusion of light.
