본 발명은 엘이디 조명기구에 관한 것으로서, 전기에너지 효율이 우수하고 수명이 반영구적인 엘이디에 광유도 확산수단이 결합됨으로써 엘이디 조명기구의 단점인 점광을 면광으로 전환하여 눈부심 현상을 방지하면서 엘이디 빛이 휘도 손실 없이 온전히 조명으로 구현되도록 하여 보다 적은 에너지로 고휘도 발산특성을 갖는 엘이디 조명기구를 상용화하도록 하는 광유도 확산수단을 구비한 엘이디 조명기구에 관한 것이다.The present invention relates to an LED lighting device, and the light induction diffuser is coupled to an LED having excellent electrical energy efficiency and a semi-permanent lifetime, thereby converting the point light, which is a disadvantage of the LED lighting device, into surface light, thereby preventing glare from occurring. The present invention relates to an LED luminaire having a light induction diffusion means for commercializing an LED luminaire having a high luminance divergence with less energy to be realized as a lighting without loss.

엘이디(LED: Light Emitting Diode)는 종래의 광원에 비하여 소형이고 수명이 길뿐만 아니라 전기에너지가 빛에너지로 직접 변환되기 때문에 전력이 적게 소모되어 에너지 효율이 우수하며 고속응답 특성을 지니고 있으므로 이러한 엘이디를 광원으로 하는 다양한 조명기구가 개발되고 있다.LED (Light Emitting Diode) is smaller and longer lifespan than the conventional light source, and because the electric energy is directly converted into light energy, it consumes less power, has high energy efficiency and has high-speed response characteristics. Various luminaires using light sources have been developed.

그러나, 엘이디는 빛이 한 점에서 '점광'되는 직진특성으로 인하여 눈부심이 매우 심하므로 시력을 손상시키는 등으로 전시장의 특수 조명 또는 차량의 전조등 등에 사용될 뿐 일반 조명기구로 사용하기에는 문제점이 있었다.However, LED has a problem in that it is used as a special lighting in the exhibition hall or the headlight of a vehicle only because the glare is very severe due to the direct characteristic that the light is 'pointed' at one point, and thus there is a problem to use it as a general lighting fixture.

또한, 이러한 눈부심 방지를 위하여 다중의 필터를 설치하기도 하지만 이 경우에는 휘도 및 전기 에너지 효율이 저하되는 문제점이 있었다.In addition, in order to prevent such glare, a plurality of filters may be installed, but in this case, there is a problem in that luminance and electrical energy efficiency are deteriorated.

본 발명은 상기한 문제점을 해소하기 위하여 안출된 것으로서,The present invention has been made to solve the above problems,

본 발명의 목적은 전기에너지 효율이 우수하고 수명이 반영구적인 엘이디에 광유도 확산수단이 결합됨으로써 엘이디 조명기구의 단점인 점광을 면광으로 전환하여 눈부심 현상을 방지하면서 엘이디 빛이 휘도 손실 없이 온전히 조명으로 구현되도록 하여 보다 적은 에너지로 고휘도 발산특성을 갖는 엘이디 조명기구를 상용화시키도록 하는 광유도 확산수단을 구비한 엘이디 조명기구에 관한 것이다.The object of the present invention is to combine the light induction diffusion means with LEDs having excellent electrical energy efficiency and lifespan semi-permanent, converting the point light, which is a disadvantage of the LED lighting fixtures into surface light, while preventing the glare phenomenon, the LED light is completely illuminated without loss of brightness The present invention relates to an LED lighting device having a light guide diffusion means for commercializing the LED lighting device having a high brightness divergence characteristics with less energy.

상기한 목적을 달성하는 본 발에 따른 광유도 확산수단을 구비한 엘이디 조명기구는 엘이디(LED: Light Emitting Diode)를 광원으로 이용하는 조명기구에 있어서,An LED lighting device having a light guide diffusion means according to the present invention for achieving the above object is a lighting device using a light emitting diode (LED) as a light source,

상기 피씨비에 접속설치되는 방열수단;을 포함하여 구성됨을 특징으로 한다.It is characterized in that it comprises a; heat dissipation means connected to the PC.

이하, 본 발명의 광유도 확산수단을 구비한 엘이디 조명기구에 대한 실시예를 첨부도면을 참조하여 보다 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, an embodiment of the LED lighting device having a light guide diffusion means of the present invention will be described in more detail.

본 발명에서 광유도 확산수단으로 채용하는 아크릴의 빛 굴절 특성을 도 1을 참고하여 살펴본다.The light refraction characteristic of the acrylic employed as the light guide diffusion means in the present invention will be described with reference to FIG.

아크릴의 빛 굴절률 n=1.49이며,The light refractive index of acrylic is n = 1.49,

아크릴의 전반사각은 이론적으로 θc=42.155 °이 산출된다.The total reflection angle of acryl is theoretically calculated as θ c = 42.155 °.

그리고 전반사 조건은 θ>θc이다. 즉 전반사는 굴절각이 42.155 °보다 클 경우에 일어난다.The total reflection condition is θ> θc. That is, total reflection occurs when the angle of refraction is greater than 42.155 °.

도 1에서 입사각을 α라 할때 '면1'에서의 굴절 법칙은 When the angle of incidence in Fig. 1 is α, the law of refraction in 'plane 1' is

sin(90-α)= n sin(90-θ)sin (90-α) = n sin (90-θ)

⇒ cosα= n cosθ  ⇒ cosα = n cosθ

⇒ θ= cos-1(1/nㆍcosθ)⇒ θ = cos -1 (1 / ncosθ)

위 식에서 θ의 범위는 0°≤α≤90°에 따라In the above formula, the range of θ depends on 0 ° ≤α≤90 °

47.84°≤θ≤90°47.84 ° ≤θ≤90 °

따라서 반드시 θ>θc 조건을 만족하므로 아크릴의 경우 항상 전반사가 이루어져 입사된 빛이 '면2'로는 절대로 발산되지 않는다. 단 표면에 스크래치가 형성된 경우에는 스크래치 부분을 통하여 빛이 발산된다.Therefore, since the condition satisfies the condition θ> θc, the total reflection is always made in the case of acrylic, and the incident light is never emitted to 'plane 2'. However, if a scratch is formed on the surface, light is emitted through the scratch portion.

본 발명은 이러한 아크릴의 빛 굴절특성을 이용하는 것이다.The present invention utilizes the light refraction characteristic of such acrylic.

본 발명에 따른 일 실시예는 도 11에 도시된 바와 같이, 상기 피씨비(13)에 설치되는 엘이디(11)가 나사결합식 소켓에 대응 형성되는 나사식 소켓접속부(21)가 구비되는 하우징(20)에 설치되며, 상기 광유도 확산수단(30)은 상기 하우징(20)에 결합되는 원주형태로 형성되고 저면과 360° 전둘레가 발광면(32)으로 구성되는 것이다.According to an embodiment of the present invention, as shown in FIG. 11, a housing 20 having a screw socket connection portion 21 in which an LED 11 installed in the PC 13 corresponds to a screw-type socket is formed. The light guide diffusion means 30 is formed in a circumferential shape that is coupled to the housing 20, and the bottom surface and the entire 360 ° circumference are configured as the light emitting surface 32.

즉, 상기 실시예는 나사식 소켓접속부(21)가 구비된 하우징(20)을 이용하여 AC 전류 통전 나사결합식 소켓에 일반 전구를 대체하여 설치가능토록 구성된 것이 다.That is, the embodiment is configured to be installed to replace the ordinary bulb in the AC current-carrying threaded socket using the housing 20 provided with the screw socket connection 21.

상기 피씨비(13)에 설치되는 방열수단(50)은 하우징(20)과 접하여 외부로 방열이 이루어지도록 구성됨이 바람직하다.The heat dissipation means 50 installed in the PC 13 is preferably configured to radiate heat to the outside in contact with the housing 20.

이때, 상기 엘이디(11)는 하나만 설치되어도 무방하며, 상기 광유도 확산수단(30)은 저면과 360° 전둘레에 스크래치(35)가 형성된다.At this time, only one LED 11 may be installed, and the light guide diffusion means 30 has a scratch 35 formed on the bottom surface and 360 ° of the entire circumference.

이와 같은 구성을 지닌 본 발명에 따른 광유도 확산수단을 구비한 엘이디 조명기구(1)의 작용상태를 살펴본다.It looks at the operating state of the LED lighting device (1) having a light guide diffusion means according to the present invention having such a configuration.

본 발명은 직진 특성으로 점광되는 엘이디의 빛을 상기 광유도 확산수단을 통하여 넓은 면적으로 확산 면광되도록 하여 눈부심을 방지하고 엘이디의 빛 효율을 살리도록 하는 것이다.The present invention is to prevent the glare and to improve the light efficiency of the LED by allowing the light of the LED pointed to the straight characteristics to diffuse the surface light to a large area through the light guide diffusion means.

만일, 엘이디의 빛을 표면이 매끈한 아크릴부재 입방체에 투과시킨다면 빛은 아크릴부재 입사점 맞은편의 한 점으로 집중 점광되므로 눈부심이 심하여 바라볼 수가 없다.If the light of the LED is transmitted to the acrylic member cube having a smooth surface, the light is concentrated at one point opposite to the acrylic member incidence point, so the glare is hard to see.

본 발명은 아크릴의 전반사 특성을 이용한 것으로서, 엘이디(11)의 빛이 상기 렌즈부(31)에서 빛이 다각도로 굴절되면서 확산되어 스크래치(35)가 형성된 발광면(32)으로만 확산 산란이 이루어져 눈부심이 방지되고, 비발광면(34)에서는 전반사가 이루어지므로 빛이 누설되는 일 없이 발광면(32)으로만 온전히 유도되어 조명효율을 향상시킨다.The present invention uses the total reflection characteristic of the acrylic, the light of the LED 11 is diffused as the light is refracted in multiple angles in the lens 31 is diffuse scattering only to the light emitting surface 32, the scratch 35 is formed Since glare is prevented and total reflection is made on the non-light emitting surface 34, light is completely guided to the light emitting surface 32 without leakage of light, thereby improving lighting efficiency.

또한, 상기 렌즈부(33)가 볼록돌부(333)로 형성될 경우에는 빛이 볼록렌즈로 기능하는 볼록돌부를 통하여 모아졌다가 다시 확산 및 굴절이 이루어진다.In addition, when the lens unit 33 is formed as the convex protrusion 333, light is collected through the convex protrusion functioning as the convex lens, and then diffused and refracted.

이와 같은 본 발명은 스크래치(35)가 형성된 발광면(32)을 엘이디 접합면(31)보다 넓게 형성하여 확산율을 증대시킨다.In the present invention as described above, the light emitting surface 32 having the scratch 35 is formed to be wider than the LED bonding surface 31 to increase the diffusion rate.

또한, 발광면(32)은 엘이디 접합면(31) 맞은편이 바람직하나 측면을 포함할 수 도 있으며, 반사지를 이용하여 맞은편이 제외될 수도 있다.In addition, the light emitting surface 32 is preferably opposite the LED bonding surface 31 may include a side surface, it may be excluded from the opposite side using a reflective paper.

따라서, 이러한 점을 이용하여 조명 용도 또는 설치위치에 따라 광유도수단(30)의 모양을 다양하게 구성할 수 있다.Therefore, the shape of the light guide means 30 can be variously configured according to the lighting use or the installation position using this point.

그리고, 발광면(32)에 형성되는 스크래치(35)는 빛이 발광면 전체에 걸쳐 균등하게 발산되도록 균일하게 형성시켜 눈부심이 방지되도록 한다.In addition, the scratches 35 formed on the light emitting surface 32 are uniformly formed so that light is evenly distributed over the entire light emitting surface, thereby preventing glare.
