도 1 내지 도 3을 참조하면, 본 발명의 제1실시예에 따른 창부재(100)는 제1투명부재(110)를 포함한다.1 to 3, the window member 100 according to the first embodiment of the present invention includes a first transparent member 110.
제1투명부재(110)는 특정 각도로 입사되는 빛에 대해서는 재귀반사를 시키고, 다른 각도로 입사되는 빛에 대해서는 투과시키는 특징을 지닌다.The first transparent member 110 has a feature of retroreflecting light incident at a specific angle and transmitting light incident at other angles.
여기서, 특정 각도로 입사되는 빛은 후술되는 전반사 조건에 해당되는 빛의 각으로 재귀반사시키고자 하는 빛이며, 다른 범위로 입사되는 빛은 전반사 조건을 벗어나 다른 각으로 투과시키고자 하는 빛을 말한다.Herein, light incident at a specific angle is light that is to be retroreflected at an angle of light corresponding to the total reflection condition described below, and light incident at other ranges is light that is to be transmitted at different angles beyond the total reflection condition.
이러한 제1투명부재(110)는 입사면(112)과 제1패턴면(115)을 포함한다. 입사면(112)은 평면으로 형성되어 외부에서 유입되는 빛이 굴절되어 입사된다. 그리고, 제1패턴면(115)은 입사면(112)의 이면에 구비되어 태양의 고도에 따라 빛을 재귀반사시키거나 투과시킨다.The first transparent member 110 includes an incident surface 112 and a first pattern surface 115. The incident surface 112 is formed in a plane such that light flowing from the outside is refracted and incident. The first pattern surface 115 is provided on the back surface of the incident surface 112 to retroreflect or transmit light according to the altitude of the sun.
제1패턴면(115)은 2개 이상의 전반사면이 반복 형성된다. 즉, 도 2에서 도시된 바와 같이 제1패턴면(115)은 제1전반사면(116a), 제1전반사면(116a)에 연이어 형성되는 제2전반사면(116b), 제2전반사면(116b)에 연이어 형성되는 제1연결면(117)으로 이루어진 패턴이 연이어 구성된다.Two or more total reflection surfaces of the first pattern surface 115 are repeatedly formed. That is, as shown in FIG. 2, the first pattern surface 115 includes a first total reflection surface 116a and a second total reflection surface 116b and a second total reflection surface 116b which are successively formed on the first total reflection surface 116a. ) Is a pattern consisting of a first connection surface 117 formed in succession.
도 1에서 도시된 바와 같이 하지의 태양 고도는 약 70° 내외이며, 동지의 태양 고도는 약 30°이다. 이로 인해 도 3에서 도시된 바와 같이 태양의 고도가 높은 하절기에는 입사되는 빛의 입사각이 임계각 보다 크게 되므로 제1,2전반사면(116a,116b)에 의해 전반사되고, 동절기에는 입사되는 빛의 입사각이 임계각 보다 작게 되므로 제1,2전반사면(116a,116b)을 통해 투과된다.As shown in FIG. 1, the sun altitude of the lower limb is about 70 ° and the sun altitude of the winter sol is about 30 °. As a result, as shown in FIG. 3, since the incident angle of the incident light is greater than the critical angle in the summer when the sun is high in height, the total reflection is performed by the first and second total reflection surfaces 116a and 116b, and the incident angle of the incident light is in the winter season. Since it becomes smaller than the critical angle, it is transmitted through the first and second total reflection surfaces 116a and 116b.
여기서, 전반사는 빛이 굴절률이 큰 매질에서 굴절률이 작은 매질로 진행할 때 입사각이 임계값보다 클 경우 경계면에서 전부 반사되는 현상이다. 일반적으로 굴절률이 큰 매질에서 굴절률이 작은 매질로 진행하면 경계면에서 일부는 투과해 나가고 일부는 반사된다. 그러나, 입사각을 점점 증가시키면 특정한 각 이상이 되었을 때 투과하는 빛은 전혀 없고 전부 경계면에서 반사한다. 이것을 전반사라고 하며, 이때의 입사각을 임계각이라고 한다. 따라서, 입사각이 임계각보다 큰 하절기에는 입사되는 빛이 제1,2전반사면(116a,116b)에 의해 전반사되고, 입사각이 임계각보다 작은 동절기에는 입사되는 빛이 제1,2전반사면(116a,116b)을 통해 투과될 수 있다.Here, the total reflection is a phenomenon in which the light is completely reflected at the interface when the incident angle is larger than the threshold value when the light proceeds from the medium having the large refractive index to the medium having the small refractive index. In general, when a medium with a high refractive index advances to a medium with a small refractive index, some of the light passes through the interface and some is reflected. However, if the angle of incidence is gradually increased, there is no light transmitted at a specific angle or more, and all of the light is reflected at the interface. This is called total reflection, and the incident angle at this time is called a critical angle. Therefore, the incident light is totally reflected by the first and second total reflection surfaces 116a and 116b in the summer when the incident angle is larger than the critical angle, and the incident light is the first and second total reflection surfaces 116a and 116b in the winter season when the incident angle is smaller than the critical angle. Can be transmitted through).
이는 제1투명부재의 굴절률을 n1, 제1투명부재의 외부매질의 굴절률을 n3라 하고, 평면으로부터 입사된 빛이 굴절되어 평면의 법선과 이루는 각을 Lin, 평면과 상기 제1전반사면(116a)이 이르는 각을 θ1, 제1전반사면(116a)과 제2전반사면(116b)의 사이각을 θ2 라고 할 때, 제1, 제2전반사면(116b)은 다음 조건을 만족하도록 구성된다. This means that the refractive index of the first transparent member is n1, the refractive index of the external medium of the first transparent member is n3, and the light incident from the plane is refracted to form an angle L in , the plane and the first total reflection surface ( When the angle reached by 116a is θ1 and the angle between the first total reflection surface 116a and the second total reflection surface 116b is θ2, the first and second reflection surfaces 116b are configured to satisfy the following conditions. .
제1전반사면의 구성조건 : θ1 > sin-1(n1/n3)-Lin Constituent conditions of the first total reflection surface: θ1> sin -1 (n1 / n3) -L in
제2전반사면의 구성조건 : sin-1(n1/n3)+θ1+Lin < θ2 < 130°Constituent conditions of the second total reflection surface: sin -1 (n1 / n3) + θ1 + L in <θ2 <130 °
그리고, n1 > n3 를 만족하여야 한다. And, n1> n3 must be satisfied.
상기한 식은 제1,2전반사면(116a,116b)의 구성을 나타낸 것으로서, 빛의 입사각(Lin)에 대해 제1전반사면(116a)의 각도 θ1이 결정되고, θ1에 의해 제2전반사면(116b)의 각도 θ2가 결정된다. 즉, 재귀반사시킬 빛의 각에 의해 제1전반사면(116a)의 각도가 결정되고, 제1전반사면(116a)에 의해 제2전반사면(116b)의 각도가 결정된다.As showing the configuration of the above expression the first and second total reflection surface (116a, 116b), the angle θ1 of the first total reflection surface (116a) is determined for the angle of incidence of light (L in), across the second surface by θ1 An angle θ2 of 116b is determined. That is, the angle of the first total reflection surface 116a is determined by the angle of the light to be retroreflected, and the angle of the second total reflection surface 116b is determined by the first reflection surface 116a.

도 4 내지 도 8을 참조하면, 본 발명의 제2실시예에 따른 창부재는 제1투명부재(110)와 제2투명부재(120)를 포함한다.4 to 8, the window member according to the second embodiment of the present invention includes a first transparent member 110 and a second transparent member 120.
제1투명부재(110)는 제1실시예와 동일하다. 즉, 제1투명부재(110)는 입사면(112)과 제1패턴면(115)을 구비한다. 그리고, 제1투명부재(110)의 후측에는 제2투명부재(120)가 구비된다. 제2투명부재(120)는 출사면(122)과 제2패턴면(125)으로 이루어지며, 이는 제1투명부재(110)의 제1패턴면(115)이 외부로 노출되는 것을 방지할 수 있다.The first transparent member 110 is the same as the first embodiment. That is, the first transparent member 110 includes an incident surface 112 and a first pattern surface 115. Then, the second transparent member 120 is provided on the rear side of the first transparent member 110. The second transparent member 120 is composed of an emission surface 122 and the second pattern surface 125, which can prevent the first pattern surface 115 of the first transparent member 110 is exposed to the outside. have.
제2투명부재(120)에는 제1투명부재(110)의 제1패턴면(115)과 평행하게 마주보도록 제2패턴면(125)이 형성된다. 제1투명부재(110)의 제1패턴면(115)은 제1,2전반사면(116a,116b)과 제1연결면(117)이 연이어 형성되어 한 패턴으로 구성되어 연이어 형성되고, 제2패턴면(125)은 제1패턴면(115)과 모든 면이 평행하게 형성된다. 즉, 제2패턴면(125) 또한, 2개 이상의 대응면(126)과, 제2연결면(127)으로 이루어진다.A second pattern surface 125 is formed on the second transparent member 120 to face in parallel with the first pattern surface 115 of the first transparent member 110. The first pattern surface 115 of the first transparent member 110 is formed by forming a pattern in which the first and second total reflection surfaces 116a and 116b and the first connection surface 117 are formed in succession, and are formed successively. The pattern surface 125 is formed in parallel with all surfaces of the first pattern surface 115. That is, the second pattern surface 125 also includes two or more corresponding surfaces 126 and a second connection surface 127.
제1투명부재(110)와 제2투명부재(120) 사이에는 간극층(130)이 구비된다. 간극층(130)은 제1투명부재(110)와 제2투명부재(120)가 일정간격 이격되어 형성되고, 내부가 진공 또는 공기로 형성될 수도 있으며, 아르곤, 크립톤 중 적어도 어느 하나의 가스가 충진될 수도 있다.The gap layer 130 is provided between the first transparent member 110 and the second transparent member 120. The gap layer 130 may be formed by spaced apart from the first transparent member 110 and the second transparent member 120 by a predetermined interval, and may be formed by vacuum or air, and at least one of argon and krypton gas may be formed. It may be filled.
상기한 구조에 의해 도 5에서 도시된 바와 같이 특정한 각도로 입사되는 빛은 제1투명부재(110)에 의해 재귀반사된다. 재귀반사는 입사면(112)으로 입사된 빛이 제1,2전반사면(116a,116b)에 의해 전반사되어 입사면(112)을 통하여 투과되는 것이다. 특정한 각도를 벗어나 입사되는 빛은 제1,2전반사면(116a,116b)을 통해 굴절되고, 제2투명부재(120)를 통해 내부로 투과되어 출사면(122)으로 통해 출사된다.The light incident at a specific angle as shown in FIG. 5 by the above structure is retroreflected by the first transparent member 110. The retroreflective light is incident on the incident surface 112 to be totally reflected by the first and second total reflection surfaces 116a and 116b and transmitted through the incident surface 112. The light incident out of a specific angle is refracted through the first and second total reflection surfaces 116a and 116b, transmitted through the second transparent member 120, and emitted through the emission surface 122.
특정 각도의 입사되는 빛은 후술되는 전반사 조건에 해당되는 빛의 각으로 재귀반사시키고자 하는 빛이며, 다른 각도로 입사되는 빛은 전반사 조건을 벗어나 다른 각으로 투과시키고자 하는 빛을 말한다.The incident light at a specific angle is light that is to be retroreflected at an angle of light corresponding to the total reflection condition described below, and the light incident at another angle is light that is to be transmitted at different angles out of the total reflection condition.
이처럼 제1투명부재(110)에 의한 재귀반사는, 도 4에서 도시된 바와 같이 제1투명부재(110)의 굴절률을 n1, 제2투명부재(120)의 굴절률을 n2, 간극층(130)의 굴절률을 n3라고 했을 때, n1 > n3, n2 > n3을 만족함으로써 가능하다.As described above, the retroreflection by the first transparent member 110 includes n1 as the refractive index of the first transparent member 110 and n2 as the refractive index of the second transparent member 120, as shown in FIG. 4. When the refractive index of is set to n3, it is possible by satisfying n1> n3 and n2> n3.
또한, 도 6에서 도시된 바와 같이 제1투명부재의 굴절률을 n1, 제2투명부재의 굴절률을 n2, 간극층의 굴절률을 n3라 하고, 평면으로부터 입사된 빛이 굴절되어 평면의 법선과 이루는 각을 Lin, 평면과 상기 제1전반사면(116a)이 이르는 각을 θ1, 상기 제1전반사면(116a)과 상기 제2전반사면(116b)의 사이각을 θ2 라고 할 때, 상기 제1, 제2전반사면(116a,116b)은 다음 조건을 만족하도록 구성된다.In addition, as shown in FIG. 6, the refractive index of the first transparent member is n1, the refractive index of the second transparent member is n2, and the refractive index of the gap layer is n3, and the light incident from the plane is refracted to form a normal line of the plane. When L in , the angle between the plane and the first total reflection surface 116a is θ1, and the angle between the first total reflection surface 116a and the second total reflection surface 116b is θ2. The second total reflection surfaces 116a and 116b are configured to satisfy the following conditions.
제1전반사면의 구성조건 : θ1 > sin-1(n1/n3)-Lin Constituent conditions of the first total reflection surface: θ1> sin -1 (n1 / n3) -L in
제2전반사면의 구성조건 : sin-1(n1/n3)+θ1+Lin < θ2 < 130°Constituent conditions of the second total reflection surface: sin -1 (n1 / n3) + θ1 + L in <θ2 <130 °
이로 인해 도 5에서 도시된 바와 같이 태양의 고도가 높은 하절기에는 입사되는 빛의 입사각이 임계각 보다 크게 되므로 제1,2전반사면(116a,116b))에 의해 전반사되고, 동절기에는 입사되는 빛의 입사각이 임계각 보다 작게 되므로 제1,2전반사면(116a,116b)을 통해 투과될 수 있다.As a result, as shown in FIG. 5, since the incident angle of the incident light is greater than the critical angle in the summer when the sun is high, the first and second total reflection surfaces 116a and 116b are totally reflected, and the incident angle of the incident light in the winter season. Since it is smaller than the critical angle, it can be transmitted through the first and second total reflection surfaces 116a and 116b.
도 8에서 도시된 바와 같이 제1투명부재(110)의 제1패턴면(115)과 제2투명부재(120)의 제2패턴면(125) 사이에는 간극층(130)이 형성되고, 제1패턴면(115)과 제2패턴면(125)이 평행하므로 굴절각이 일정하게 되어 왜곡이 일어나지 않고 가시성이 향상된다.As shown in FIG. 8, a gap layer 130 is formed between the first pattern surface 115 of the first transparent member 110 and the second pattern surface 125 of the second transparent member 120. Since the first pattern surface 115 and the second pattern surface 125 are parallel to each other, the angle of refraction becomes constant so that distortion is not generated and visibility is improved.
제1투명부재(110)와 제2투명부재(120)는 유리 또는 플라스틱 재질로 이루어진다. 즉, 제1,2투명부재가 동일한 유리나 플라스틱의 단일 재질로 이루어질 수도 있고, 제1,2투명부재가 서로 다른 재질로 이루어질 수도 있다.The first transparent member 110 and the second transparent member 120 is made of a glass or plastic material.

The reinforcing transparent member 140 may reinforce the mechanical properties of the window member 100 with a general window.
이하, 상기한 구조를 갖는 본 발명의 제1,2실시예에 따른 창부재(100)의 작용 및 효과를 설명하면 다음과 같다.Hereinafter, the operation and effects of the window member 100 according to the first and second embodiments of the present invention having the above structure will be described.
본 발명의 제1실시예에 따른 창부재(100)는 제1투명부재(110)로 이루어진다. 제1투명부재(110)는 입사면(112)과 입사면(112)의 이면에 형성되는 제1패턴면(115)으로 이루어지는데, 제1패턴면(115)에 의해 외부에서 유입되는 빛이 고도에 따라 재귀반사하거나 투과될 수 있다.The window member 100 according to the first embodiment of the present invention consists of a first transparent member 110. The first transparent member 110 is composed of the incident surface 112 and the first pattern surface 115 formed on the back surface of the incident surface 112, the light flowing from the outside by the first pattern surface 115 Depending on the altitude, it can be retroreflective or transmitted.
이러한 작용은 제1투명부재의 굴절률을 n1, 제1투명부재의 외부매질의 굴절률을 n3라 하고, 평면으로부터 입사된 빛이 굴절되어 평면의 법선과 이루는 각을 Lin, 평면과 제1전반사면(116a)이 이르는 각을 θ1, 제1전반사면(116a)과 제2전반사면(116b)의 사이각을 θ2 라고 할 때, 제1전반사면(116a)은 θ1 > sin-1(n1/n3)-Lin 를 만족하고, , 제2전반사면(116b)은 sin-1(n1/n3)+θ1+Lin < θ2 < 130°를 만족함으로써 가능하다. 이때, n1 > n 3를 만족하여야 한다.This action is referred to as the refractive index of the first transparent member n1, the refractive index of the external medium of the first transparent member is n3, the light incident from the plane is refracted to form the angle L in , the plane and the first total reflection surface When the angle reached by 116a is θ1 and the angle between the first total reflection surface 116a and the second total reflection surface 116b is θ2, the first total reflection surface 116a is θ1> sin −1 (n1 / n3 ) satisfies -L in, and the second total reflection surface (116b) is possible by satisfying sin -1 (n1 / n3) + θ1 + L in <θ2 <130 °. At this time, n1> n 3 must be satisfied.
이를 자세히 살펴보면, 도 3에서 도시된 바와 같이 태양의 고도에 따라 유입되는 빛의 입사각은 상이하며, 입사각에 따라 빛을 제1,2전면사면(116a,116b)에 의해 전반사하여 재귀반사하거나, 투사될 수 있는 것이다. 즉, 태양의 고도가 높은 하절기의 경우, 입사되는 빛의 입사각이 임계각 보다 크게 되므로 제1,2전반사면(116a,116b))에 의해 전반사되어 빛을 재귀반사시킴으로써, 차폐계수(Shading Coefficient:SC), 일사취득계수(Solar Heat Gain Coefficient:SHGC)를 낮출 수 있다.In detail, as shown in FIG. 3, the incidence angle of the light introduced according to the altitude of the sun is different, and the total reflection of the light by the first and second front slopes 116a and 116b is reflected back or the projection is performed according to the incidence angle. It can be. That is, in the summer when the sun is high altitude, since the incident angle of the incident light is greater than the critical angle, the total reflection by the first and second total reflection surfaces 116a and 116b) causes the light to be retroreflected so that the shading coefficient (SC) ), The solar heat gain coefficient (SHGC) can be lowered.
이로 인해, 실내의 냉방부하를 감소시킬 수 있고, 실내 눈부심을 줄일 수 있으며, 빛 반사 피해를 줄일 수 있다. 또한, 도시 열섬현상(heat island)을 감소시키고, 직접 자연광을 반사시키며, 간접 자연광은 적절히 유입되므로 조명부하를 감소시키는 효과를 지닌다.As a result, the cooling load of the room can be reduced, the glare of the room can be reduced, and the light reflection damage can be reduced. In addition, it reduces the city heat island (heat island), directly reflects the natural light, and indirect natural light is properly introduced has the effect of reducing the lighting load.
그리고, 태양의 고도가 낮은 동절기의 경우, 동절기에는 입사되는 빛의 입사각이 임계각 보다 작게 되므로 제1,2전반사면(116a,116b)을 통해 투과됨으로써, 차폐계수(Shading Coefficient:SC), 일사취득계수(Solar Heat Gain Coefficient:SHGC)를 높일 수 있으며, 난방부하를 감소시켜 에너지 사용이 절감된다.In winter, when the sun's altitude is low, the incident angle of the incident light in winter is smaller than the critical angle, so that the light is transmitted through the first and second total reflection surfaces 116a and 116b, thereby obtaining shading coefficient (SC) and solar radiation. It can increase the Solar Heat Gain Coefficient (SHGC) and reduce the energy load by reducing the heating load.
또한, 자연 채광성능이 높아져서 조명부하가 감소된다.In addition, the natural light performance is increased, the lighting load is reduced.
도 13은 본 발명에 따른 창부재(100)에 의한 계절별 투과율을 보인 그래프로서, 태양의 고도가 낮은 겨울에는 투과율이 높아 난방부하를 감소시켜 에너지 사용이 절감될 수 있고, 봄과 가을은 적절한 투과율을 유지할 수 있으며, 태양의 고도가 높은 여름에는 투과율이 낮아 냉방부하를 감소시키고, 실내 눈부심을 방지할 수 있다.FIG. 13 is a graph showing seasonal transmittance by the window member 100 according to the present invention. In the winter, when the sun's altitude is low, the transmittance is high, and thus the heating load is reduced, and energy use is reduced in the spring and autumn. In the summer when the sun's altitude is high, the transmittance is low, reducing the cooling load and preventing indoor glare.

즉, 도 4에서 도시된 바와 같이 제1실시예와 달리 제1투명부재(110)의 제1패턴면(115)이 제2투명부재(120)에 의해 외부로 노출되지 않는 구조를 지닌다. 제1패턴면(115)이 외부로 노출되지 않으므로 청소 및 날카로운 면에 의한 안전사고를 방지할 수 있다.That is, as shown in FIG. 4, unlike the first embodiment, the first pattern surface 115 of the first transparent member 110 is not exposed to the outside by the second transparent member 120. Since the first pattern surface 115 is not exposed to the outside, safety accidents due to cleaning and sharp surfaces can be prevented.
그리고, 제2투명부재(120)에는 제1투명부재(110)의 제1패턴면(115)과 대응되게 형성되는 제2패턴면(125)이 형성된다. 제2패턴면(125)은 제1패턴면(115)에 평행하게 형성되며, 제1패턴면(115)과 제2패턴면(125)의 사이에는 간극층(130)이 형성된다.In addition, the second transparent member 120 has a second pattern surface 125 formed to correspond to the first pattern surface 115 of the first transparent member 110.

Assuming that n3 is satisfied, n1> n3 and n2> n3 are satisfied.
그리고, 제1투명부재(110)의 굴절률을 n1, 제2투명부재(120)의 굴절률을 n2, 간극층(130)의 굴절률을 n3라 하고, 평면으로부터 입사된 빛이 굴절되어 평면의 법선과 이루는 각을 Lin, 평면과 제1전반사면(116a)이 이르는 각을 θ1, 제1전반사면(116a)과 제2전반사면(116b)의 사이각을 θ2 라고 할 때, 제1전반사면(116a)은 θ1 > sin-1(n1/n3)-Lin 를 만족하고, 제2전반사면(116b)은 sin-1(n1/n3)+θ1+Lin < θ2 < 130°를 만족함으로써 가능하다.The refractive index of the first transparent member 110 is n1, the refractive index of the second transparent member 120 is n2, and the refractive index of the gap layer 130 is n3. When the angle formed by L in , the plane and the first total reflection surface 116a is θ1 and the angle between the first total reflection surface 116a and the second total reflection surface 116b is θ2, the first total reflection surface ( 116a) satisfies θ1> sin -1 (n1 / n3) -L in , and the second total reflection surface 116b satisfies sin -1 (n1 / n3) + θ1 + L in <θ2 <130 °.
