조사각 확장 엘이디 램프{SHEDDING AREA EXPANSION LED LAMP}Beam angle expansion LED lamps {SHEDDING AREA EXPANSION LED LAMP}

본 발명은 광유도 확산수단에 빛 확산을 위한 경사면이 형성됨으로써 엘이디 램프의 조사각 및 조사영역을 현저히 향상시켜 주도록 하는 조사각 확장 엘이디 램프에 관한 것이다.The present invention relates to a radiation angle extended LED lamp to significantly improve the irradiation angle and the irradiation area of the LED lamp by forming the inclined surface for light diffusion in the light guide diffusion means.

엘이디(LED: Light Emitting Diode)는 종래의 광원에 비하여 소형이고 수명이 길뿐만 아니라 전기에너지가 빛에너지로 직접 변환되기 때문에 전력이 적게 소모되어 에너지 효율이 우수한 고광도를 발하는 특성을 지니고 있다.LED (Light Emitting Diode) is smaller and longer lifespan than the conventional light source, and because the electric energy is directly converted to light energy, it consumes less power and has a characteristic of emitting high brightness with excellent energy efficiency.

따라서, 이러한 엘이디를 광원으로 하는 다양한 조명기구가 개발되고 있으며, 근래에는 기존의 백열전구 소켓 또는 12V 소형 할로겐램프 소켓에 호환설치가 가능한 소형 엘이디 램프가 큰 호응을 얻고 있다.Therefore, various luminaires using such LEDs as light sources have been developed, and recently, small LED lamps compatible with existing incandescent lamp sockets or 12V small halogen lamp sockets have gained great response.

그런데, 기존의 백열전구는 소켓이 위치하는 직상부를 제외한 전방향을 비추는데 비하여 엘이디는 조사각이 110°내외에 그쳐 둘레 측방향이 조명 사각지대로 되는 등 조명범위가 협소한 문제점이 있다.By the way, the conventional incandescent light bulb shines in all directions except the upper portion where the socket is located, LED has a narrow illumination range, such that the irradiation angle is only about 110 ° and the circumferential side is a blind spot.

도 1 내지 도 3에 도시된 바와 같이, 본 발명에 따른 일 실시예의 조사각 확장 엘이디 램프(1)는 하나 이상의 엘이디(LED: Light Emitting Diode)(11) 및 엘이디실장 피씨비(13)를 포함하는 광원부(10)와 상기 광원부(10)를 수용 지지하며 방열기능을 갖는 방열하우징(30)과 상기 방열하우징(30) 상부에 구비되며 할로겐램프형 또는 전구형으로 되는 전원연결부(50)를 포함하여 구성되는 엘이디 램프에 있어서, 상기 광원부(10) 하방에 투광커버를 겸하여 설치되고 엘이디 빛의 조사각을 확장하기 위한 광유도 확산수단(60)을 포함하여 구성되며, 상기 광유도 확산수단(60)은 투광체로 되고 엘이디(11)의 빛이 입사되는 수광부(61)와 빛이 발산되는 발광부(63)를 구비하되 상기 발광부(63)는 엘이디 빛을 외곽으로 확산시키기 위한 경사면(631)이 내측으로 형성되는 것이다.As shown in Figs. 1 to 3, the irradiation angle extended LED lamp 1 of one embodiment according to the present invention includes at least one LED (Light Emitting Diode) 11 and an LED mounting PC 13 The light source unit 10 and the light source unit 10 accommodates and supports the heat dissipation housing 30 having a heat dissipation function and the power supply unit 50 is provided on the heat dissipation housing 30, the halogen lamp type or bulb type; In the LED lamp is configured to include a light guide cover below the light source unit 10 and includes a light guide diffusion means 60 for extending the irradiation angle of the LED light, the light guide diffusion means 60 Is a light-transmitter and includes a light receiving part 61 to which light of the LED 11 is incident and a light emitting part 63 to emit light, wherein the light emitting part 63 has an inclined surface 631 for diffusing the LED light to the outside. It is formed inward.

여기서, 상기 광원부(10)는 엘이디(11)가 원형 또는 다각형 형태로 피씨비 둘레에 배열되고, 상기 광유도 확산수단(60)은 엘이디(11) 배열에 대응하여 경사면(631)이 형성되어 하방에 하광상협의 요입공간(633)이 형성됨이 바람직하다.Here, the light source unit 10 has an LED 11 is arranged around the PCB in a circular or polygonal shape, the light induction diffusion means 60 is inclined surface 631 is formed to correspond to the arrangement of the LED 11 below Preferably, the concave convex space 633 is formed.

엘이디(11)는 방열을 위하여 최대한 피씨비(13)의 가장자리에 근접위치됨이 바람직하며, 상기 경사면(631)은 엘이디 위치 하방에 위치하여 발광부(63)의 가장자리 내측에 둘러형성되고 이에 따라 광유도 확산수단(60)은 하광상협의 요입공간(633)을 형성하게 된다.The LED 11 is preferably positioned as close to the edge of the PC 13 as possible for heat dissipation, and the inclined surface 631 is positioned below the LED position to surround the inside of the edge of the light emitting part 63 and thus mineral oil. The diffusing means 60 also forms a concave convex space 633 of the lower light negotiation.

또한, 상기 광유도 확산수단(60)은 상부 외주면에 나사산(65)을 형성하여 이에 대응하는 나사부(35)가 형성된 방열하우징(30)에 나사결합됨이 바람직하다.In addition, the light guide diffusion means 60 is preferably screwed to the heat dissipation housing 30 is formed with a screw thread (65) formed on the upper outer circumferential surface.

한편, 도 1 내지 도 3은 전원연결부(50)가 나사결합되는 전구형으로 구성된 것이고, 도 4는 핀결합되는 할로겐램프형으로 이루어진 것을 도시한 것이다. On the other hand, Figures 1 to 3 are configured in the bulb type to which the power connection 50 is screwed, Figure 4 shows that made of a halogen lamp type to be pin-coupled.

상기 광유도 확산수단(60)은 유리, 아크릴, 폴리스틸렌 등으로 이루어지고, 상기 경사면(631)의 경사각(α)은 다양하게 형성될 수 있으며 아크릴로 형성될 경우 33.2°가 바람직하다.The light induction diffusion means 60 is made of glass, acrylic, polystyrene, etc., the inclination angle (α) of the inclined surface 631 may be formed in various ways, 33.2 ° is preferred when formed of acrylic.

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

빛은 그 경로를 최소화하여 진행하는 성질로 인하여 두 매질의 경계면에서 반사와 굴절을 일으키는데 이는 빛이 광학적으로 밀도가 다른 두 매질의 경계면에 닿으면 두 매질 속에서 진행 속도가 다르기 때문에 일어난다.Light causes reflection and refraction at the interface of the two media due to its minimal propagation, which occurs because the speed of propagation in the two media is different when light reaches the interface of two optically dense media.

광학적으로 소(疏)ㆍ밀(密)을 이룬 두 매질의 경계면에 빛이 입사할 때의 굴 절율은 두 물질의 소ㆍ밀의 차가 클수록, 또 입사각이 클수록 커지고, 입사각이 커져서 어떤 각도가 되면 굴절각이 90°가 된다. 이것은 굴절 빛살이 경계면을 따라 진행함을 의미한다.The refractive index when light enters the interface between two optically small and medium media is larger as the difference between the small and the two materials and the larger the angle of incidence becomes larger, and the angle of incidence becomes larger. Is 90 °. This means that the refraction light travels along the interface.

이 때의 입사각을 임계각이라 하고 임계각보다 큰 각도로 빛이 입사하면 빛은 경계면에서 100% 내부로 반사하게 되며, 이런 현상을 '내부전반사'라 부른다.At this time, the incident angle is called the critical angle. When light enters at an angle greater than the critical angle, the light is reflected 100% from the boundary surface. This phenomenon is called 'internal reflection'.

그리고, 빛의 굴절률은 매질에 따라 다르다(표 1 참조).In addition, the refractive index of the light depends on the medium (see Table 1).

Figure 112008070363450-pat00001
Figure 112008070363450-pat00001

엘이디(11)로부터 발사되는 빛은 광유도 확산수단(60)에서 110°내외 범위로 입사 확산되되 중심 30° 범위 안에 광량의 50% 이상이 집중되며(도 5 참조), 빛이 광유도 확산수단의 경사면(631)에서 매질이 다른 공기중으로 나갈 때 상기와 같이 반사 및 굴절이 발생되고 굴절각이 임계각 이상으로 될 경우 내부 전반사가 일어난다(도 6 참조). 도 6에서 가장 큰 각도로 굴절되는 광선(b1)이 전반사 임계광이다. The light emitted from the LED 11 is incident diffused from the light induction diffusion means 60 in the range of about 110 °, but more than 50% of the light is concentrated within the center 30 ° range (see FIG. 5), and the light is the light induction diffusion means. When the medium exits the other air in the inclined surface 631 of the above, reflection and refraction occur as described above, and the total internal reflection occurs when the angle of refraction exceeds the critical angle (see FIG. 6). In FIG. 6, the light ray b1 refracted at the greatest angle is the total reflection critical light.

이러한 빛의 굴절 및 반사원리를 이용한 본원발명의 빛 확산 과정을 빛의 임계상황을 도시한 도 7을 참고하여 구체적으로 살펴본다.The light diffusion process of the present invention using the refraction and reflection principle of the light will be described in detail with reference to FIG. 7 illustrating a critical state of light.

광유도 확산수단(60)이 굴절률이 약 1.5(실제는 1.49)인 아크릴로 형성될 경우, 임계상황의 전반사각은 θ=Sin-1(1/1.5)=41.8°로 된다.When the light guide diffusion means 60 is formed of acrylic having a refractive index of about 1.5 (actually 1.49), the total reflection angle of the critical situation is θ = Sin −1 (1 / 1.5) = 41.8 °.

그리고, 엘이디 빛 발사각:π, 광유도 확산수단의 경사면 경사각:α, 최종 최대 굴절각:β라 할 때, A점에서 θ+π+α= 90°의 관계를 알수 있다(도 7의 A점을 발체 도시한 도 8 참조).In addition, when the LED light emission angle: π, the inclined plane inclination angle of the light-induced diffusion means: α, and the final maximum refraction angle: β, a relationship of θ + π + α = 90 ° from point A can be seen (point A in FIG. See Figure 8 in full body).

따라서, 엘이디(11)에서 발사되는 빛 중 발사각도가 π=90°-θ-α=48.2-α°보다 작은 광선은 모두 전반사 되고, π=15°이므로 α=33.2°가 된다.Therefore, among the light emitted from the LED 11, all light beams whose firing angle is smaller than π = 90 ° -θ-α = 48.2-α ° are totally reflected, and since π = 15 °, α = 33.2 °.

또한, B점에 입사되는 빛의 입사각(φ)은 도 7을 일부 발췌 도시한 도 9에서 알 수 있는 바와 같이, φ=π+2θ-90°=π-6.4°Incidentally, the incident angle φ of the light incident on the point B is φ = π + 2θ-90 ° = π-6.4 °, as can be seen in FIG.

Sinβ =1.5ㆍSin(π-6.4°)Sinβ = 1.5Sin (π-6.4 °)

β = Sin-1[1.5ㆍSin(π-6.4°)]β = Sin -1 [1.5Sin (π-6.4 °)]

π=15°를 대입하면 β= 13.0°가 된다.Substituting π = 15 ° results in β = 13.0 °.

상술한 빛의 굴절 관계를 정리하면 엘이디(11)의 집중 발사각 15°(온각 30°중 수직 이등분 된 부분) 범위의 빛을 반사ㆍ확산시키는 광유도 확산수단(60)의 경사면(631)의 경사각(α)은 33.2°가 바람직하며, 이때 광유도 확산수단(60) 외주면에서의 굴절각 (β)은 13.0°이므로 광유도 확산수단(60)의 빛 발사 온각(1θ)은 전방향에 가까운 154°가 되어 측방향 사각지대를 해소한다(도 3 참조).In summary, the inclination angle of the inclined surface 631 of the light guide diffusion means 60 for reflecting and diffusing light in the range of 15 ° (the vertically bisected portion of the warm angle 30 °) of the LED 11 is summarized. (α) is preferably 33.2 °, and the angle of refraction (β) at the outer circumferential surface of the light guide diffusion means 60 is 13.0 °, so that the light emission warm angle 1θ of the light guide diffusion means 60 is 154 ° close to the front direction. To eliminate the lateral blind spot (see Figure 3).

이상과 같이 본 발명은 엘이디(11)로부터 방사된 빛이 광유도 확산수단(60)으로 입사되고, 그 빛의 일부가 상기 경사면에서 내부반사되어 외주면으로 굴절됨으로써 조사각을 현저히 확장시킨다.As described above, according to the present invention, the light emitted from the LED 11 is incident on the light guide diffusion means 60, and a part of the light is internally reflected on the inclined surface and refracted to the outer circumferential surface, thereby significantly extending the irradiation angle.

즉, 엘이디(11)의 빛이 광유도 확산수단(60)에 일정각도(예: 110°) 범위로 입사되고 그 중 광량이 집중되는 30°범위의 절반량이 내부 전반사되어 외주면으로 굴절 확산되므로 엘이디 조사영역이 154°범위로 확장될 뿐만 아니라 빛의 중앙부집중을 방지하여 휘도를 균일하게 하고 엘이디 램프 측방향의 조명사각지대 발생을 해소시킨다.That is, since the light of the LED 11 is incident on the light induction diffusion means 60 at a predetermined angle (for example, 110 °), half of the 30 ° range in which the amount of light is concentrated is totally internally reflected and refracted to the outer circumferential surface. The irradiation area not only extends to the 154 ° range, but also prevents the central concentration of light, making the luminance uniform and eliminating the occurrence of lighting blind spots on the side of the LED lamp.

이상과 같이 본 발명은 광유도 확산수단*60)에 빛 확산을 위한 경사면(31)이 형성됨으로써 엘이디(11)의 빛이 램프의 전둘레 측방향으로 확산되어 조사각 및 조사영역이 현저히 확장됨으로써 엘이디 램프(1)의 조명성능 및 품질을 향상시켜 준다.As described above, according to the present invention, the inclined surface 31 for diffusing light is formed in the light induction diffusing means * 60, so that the light of the LED 11 is diffused in the lateral direction of the lamp, so that the irradiation angle and the irradiation area are significantly expanded. It improves the lighting performance and quality of the LED lamp (1).
