Description

전구형 엘이디 램프{Bulb-Shaped LED Lamp}Bulb-Shaped LED Lamp

본 발명은 광유도형 벌브가 빛의 굴절 및 내부전반사 특성을 이용하여 빛을 유도 확산시켜 둘레 측방향을 포함하는 전체 외표면으로 균일하게 발산시키므로 전구형 엘이디 램프에서도 전방향으로 조도가 균일하게 조사되는 동시에 눈부심이 없어 조명품질이 현저히 향상되도록 하는 전구형 엘이디 램프에 관한 것이다.In the present invention, the light-induced bulb is uniformly radiated in all directions because the light is uniformly radiated to the entire outer surface including the circumferential direction by inducing and diffusing light by using the refraction and internal reflection characteristics of the light. At the same time there is no glare and relates to a bulb-type LED lamp to significantly improve the lighting quality.

엘이디(LED: Light Emitting Diode)는 종래의 광원에 비하여 소형이고 수명이 길뿐만 아니라 전기에너지가 빛에너지로 직접 변환되기 때문에 에너지 효율이 우수한 특장점으로 조명기구의 광원으로 다양하게 개발되고 있다.LED (Light Emitting Diode) is small and long life compared to the conventional light source, and because the electrical energy is directly converted to light energy, it is a feature of excellent energy efficiency has been developed as a light source of lighting fixtures.

이러한 엘이디 조명기구 중 기존 사용하고 있는 전구용 소켓에 호환 가능하게 전원베이스가 구비된 전구형 엘이디 램프가 선호되고 있다.Among such LED lighting fixtures, bulb-type LED lamps having a power base compatible with existing bulb sockets are preferred.

그런데, 엘이디는 빛이 직진 및 집중되는 특성으로 인하여 직하방향과 둘레방향의 조도차가 심하여 조명품질이 현저히 떨어지는 문제점이 있다.However, the LED has a problem that the illumination quality is significantly lowered due to the severe difference in roughness between the direct direction and the circumferential direction due to the characteristic that the light is straight and concentrated.

즉, 백열전구 램프의 경우 빛이 램프의 직하방 공간이나 측방향 공간이 조도 차가 거의 없는데 반하여 종래기술에 따른 전구형 엘이디 램프는 빛 발산이 중앙부분으로 집중되면서 램프의 직하방 공간으로 광량의 대부분이 발산되어 직하방은 지나치게 밝고 눈부심이 강한 반면에 둘레의 측방향 부분은 현저히 어둡다는 단점이 있다.That is, in the case of incandescent bulb lamps, the light is directly below or near the lateral space of the illuminance difference, whereas the bulb-type LED lamp according to the prior art has a large amount of light into the space directly below the lamp while the light emission is concentrated in the center part. This divergence has the disadvantage that the downside is too bright and strong glare, while the lateral part of the circumference is significantly darker.

한편, 종래 기술에서는 광확산 및 눈부심 방지를 위하여 벌브에 광확산재를 코팅하거나 다중의 필터를 설치하기도 하지만 이 경우에는 휘도가 저하되는 문제점이 있다.On the other hand, in the prior art, although the light diffusion material is coated on the bulb or multiple filters are installed in order to prevent light diffusion and glare, in this case, there is a problem that the brightness is lowered.

이와 같은 구성을 지닌 본 발명에 따른 전구형 엘이디 램프(1)의 작용상태를 살펴본다.It looks at the working state of the bulb-shaped LED lamp 1 according to the present invention having such a configuration.

본 발명에서 광유도형 벌브(30)를 형성하는 아크릴의 빛 굴절 특성을 도 11을 참고하여 살펴보면,Looking at the light refractive characteristics of the acrylic forming the light-induced bulb 30 in the present invention 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 °가 산출되고, 내부전반사 조건은 θ>θc이다. 즉 전반사는 굴절각이 42.155 °보다 클 경우에 일어난다.The total reflection angle of acryl is theoretically calculated as θc = 42.155 °, and the internal total reflection condition is θ> θc. That is, total reflection occurs when the angle of refraction is greater than 42.155 °.

도 11에서 입사각을 α라 할때 '면1'에서의 굴절 법칙은 In FIG. 11, when the incident angle is α, the law of refraction at 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 평탄면을 정확히 유지할 경우, 항상 내부전반사가 이루어져 입사된 빛이 '면2'로는 발산되지 않는다. 단 표면에 스크래치가 형성된 경우에는 굴절각이 작아져 이 스크래치 부분을 통하여 빛이 발산된다.Therefore, since the condition satisfies the condition θ> θc, when the acrylic plane maintains the flat plane accurately, the internal reflection is always performed, and the incident light does not diverge to 'plane 2'. However, when a scratch is formed on the surface, the angle of refraction becomes small and light is emitted through the scratch portion.

본 발명의 광유도형 벌브(30)는 이러한 빛의 굴절 및 내부전반사 특성을 이용하는 것이다.The light-induced bulb 30 of the present invention utilizes such light refraction and total internal reflection characteristics.

즉, 아크릴 등으로 이루어진 상기 광유도형 벌브(30)는 선단에 형성된 수광부(31)을 통하여 입사된 엘이디(11)의 빛이 내부전반사에 의하여 몸체의 두께부를 타고 유도되고 확산되어 외표면으로 발산된다.That is, the light induction bulb 30 made of acryl or the like is led through the light reflecting portion 31 formed at the front end of the light emitting part 11 is guided through the thickness of the body by the total reflection and diffused to the outer surface .

광유도형 벌브(30)는 평판체가 아닌 구형태로 형성되므로 엘이디의 빛 진행방향 대비 각도차가 크지 않은 주벽부분(32)은 돔부분(34)에 비하여 빛 확산 및 발산량이 적은데 상기와 같이, 수광부(31)가 요철 형성되거나 렌즈부(313)가 형성됨으로써 광유도형 벌브(30)에 대한 엘이디(11) 빛의 입사각이 현저히 확장되어 주벽부분(32)으로 유도되는 광량을 증대시키고 빛의 확산 및 조도균일화를 현저히 향상시킨다.Since the light-induced bulb 30 is formed in a spherical shape instead of a flat plate, the circumferential wall portion 32 having a large angle difference with respect to the LED's light propagation direction has a smaller amount of light diffusion and divergence than the dome portion 34. 31 is formed unevenly or the lens portion 313 is formed, the angle of incidence of the LED 11 light to the light-induced bulb 30 is significantly expanded to increase the amount of light that is directed to the main wall portion 32, the light diffusion and illuminance Significantly improves uniformity.

여기에 더하여 주벽부분(32)에 스크래치(33) 또는 샌딩요철 등이 형성될 경우, 엘이디 빛 발산량이 더욱 증대되고, 엘이디 빛의 직진방향 영역에 반사돗트(39)가 프린팅될 경우, 직진투과되는 빛이 내부로 반사 확산되어 전체적인 빛 확산 균일도를 극대화시킨다.In addition, when the scratch 33 or sanding irregularities, etc. are formed in the circumferential wall portion 32, the LED light divergence amount is further increased, and when the reflective dot 39 is printed in the LED light direction, the straight line is transmitted. Light is reflected diffused inside, maximizing the overall light spread uniformity.

따라서, 광유도형 벌브(30)는 돔부분(34)과 함께 둘레 주벽부분(32)으로 빛의 발산이 균일하게 이루어지며, 상기 반사부재(60)는 빛의 내부손실을 방지함과 아울러 조도 균일화를 강화시켜 준다.Accordingly, the light-induced bulb 30 is uniformly radiated to the peripheral circumferential wall portion 32 together with the dome portion 34, and the reflecting member 60 prevents internal loss of light and uniformity of illuminance. Strengthens.

이에 따라, 엘이디(11)의 빛이 램프의 직하공간은 물론이고 둘레의 측방향 공간으로 균일하게 발산되어 램프 설치공간의 조도가 균일하게 되고 눈부심을 방지 하는 전구형 엘이디 램프를 구현한다.Accordingly, the light of the LED 11 is uniformly radiated to the lateral space of the circumference as well as the space directly under the lamp, so that the illuminance of the lamp installation space is uniform and implements a bulb-type LED lamp to prevent glare.

이상과 같이 본 발명은 광유도형 벌브가 빛의 굴절 및 내부전반사 특성을 이용하여 빛을 유도 확산시켜 둘레 측방향을 포함하는 전체 외표면으로 균일하게 발산시키므로 전구형 엘이디 램프에서도 전방향으로 조도가 균일하게 조사되는 동시에 눈부심이 없는 고휘도를 구현하여 조명품질을 현저히 향상시킨다.As described above, in the present invention, since the light-induced bulb induces and diffuses light by using light refraction and total internal reflection characteristics, the light is uniformly radiated to the entire outer surface including the circumferential direction, so that even the bulb type LED lamp has uniform illumination in all directions. The lighting quality is greatly improved by realizing high brightness without glare while being irradiated.
