일반적으로 선풍기는 모터의 회전력을 날개로 전달하여 바람을 일으킴으로써 피사체인 신체의 열을 빼앗아 가도록 된 공랭식 냉각장치의 일종이다.In general, a fan is a type of air-cooled cooling device that takes the heat of the body as a subject by transmitting the rotational force of the motor to the wings to generate wind.

그러나, 이와 같은 종래의 선풍기는 실용적인 측면만을 고려하여 설계되어 왔기 때문에 선풍기본체에 대한 디자인의 변화는 많이 있었지만 선풍기날개 부분에 대한 시각적인 요소의 개선은 거의 이루어지지 못하는 실정이어서, 사용자에게 지루함을 주게 되고, 제품을 차별화 하는데 한계가 있었다.However, since the conventional fan has been designed in consideration of practical aspects only, there have been many changes in the design of the fan body, but the visual elements of the fan blades are hardly improved, which causes boring to the user. There was a limit to differentiating the product.

즉, 선풍기날개는 그 형상에 따라 에너지 변환효율이나 바람의 세기, 전력소모 등에 큰 영향을 미칠 수 있기 때문에 최적형상에서 큰 변화 없이 일정한 형태로 유지될 수밖에 없었던 것이다.In other words, since the fan blades may have a great influence on energy conversion efficiency, wind strength, power consumption, etc., the fan blades have to be kept in a constant shape without significant change in the optimum shape.

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 선풍기날개에 의한 선택적으로 시각적인 아름다움과 즐거움을 제공해 줄 수 있고, 제품을 차별화 할 수 있는 발광다이오드를 갖는 선풍기날개를 제공함에 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a fan fan having a light emitting diode that can provide a visual beauty and enjoyment selectively by the fan blade, the product can be differentiated .

이하 본 발명에 따른 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1에 도시된 바와 같이 선풍기모터(30)의 고정자(32)에 착탈되도록 설치되어 고정체 상에 서로 교번되게 다른 극성을 띄도록 설치되는 복수 이상의 영구자석(N)(S)과, 선풍기날개(40)의 콘(42) 후부에 상기 영구자석(N)(S)과 근접되도록 설치되어 회전력에 의해 유도전력을 발생시키는 코일(50)과, 상기 선풍기날개(40)의 콘(42)에 설치되고, 상기 코일(50)에 접속되어 유도전력에 의해 점등되는 발광다이오드(LED1)(LED2)(LED3)(LED4)로 구성하였다.1 and a plurality of permanent magnets (N) (S) installed so as to be detached to the stator 32 of the fan motor 30 is installed to have a different polarity alternately on the fixture, as shown in Figure 1, The coil 50 of the fan blade 40 is installed to the rear of the permanent magnet (N) (S) to be in close proximity to generate the induced power by the rotational force, and the cone 42 of the fan blade 40 ) And a light emitting diode (LED1) (LED2) (LED3) (LED4) connected to the coil (50) and lit by induction power.

여기서 상기 발광다이오드(LED1)(LED2)(LED3)(LED4)를 상기 콘(42)의 정면에 서로 다른 반경을 갖도록 설치하여 정면에서 링형태로 점등되는 패턴이 얻어지도록 구성하였으며, 서로 다른 컬러의 발광다이오드(LED1)(LED2)(LED3)(LED4)를 사용하여 다색(多色)으로 점등되도록 구성하였다.Here, the light emitting diodes LED1, LED2, LED3, and LED4 are installed to have different radii on the front of the cone 42 to obtain a pattern to be turned on in a ring shape on the front, and have different colors. The light emitting diodes (LED1) (LED2) (LED3) (LED4) were used to be lit in multiple colors.

또한, 상기 발광다이오드(LED1)(LED2)(LED3)(LED4)는 코일(50)과 접속된 후 콘(42)의 후면으로부터 삽입되어 정면으로 노출되고, 코일(50)은 콘(42)의 내측에 위치된 리브에 삽입한 후 내부를 예컨대, 에폭시와 같은 몰딩재(90)로 채워서 발광 다이오드(LED1)(LED2)(LED3)(LED4)와 코일(50)이 움직이지 못하도록 고정하였다.Further, the light emitting diodes LED1, LED2, LED3, and LED4 are connected to the coil 50 and then inserted from the rear surface of the cone 42 to be exposed to the front, and the coil 50 of the cone 42 is exposed. After inserting into the rib located inside, the inside was filled with a molding material 90 such as epoxy to fix the light emitting diodes LED1 (LED2) (LED3) (LED4) and the coil 50 so as not to move.

또, 상기 영구자석(N)(S)을 설치하기 위한 고정체는 선풍기망(70)과 선풍기 모터(30)를 연결하는 너트(80)로 구성될 수 있으나 꼭 이러한 고정체에 한정하지 않고, 영구자석(N)(S)이 금속제 망체에 자력으로 부착되도록 하여, 착탈이 가능하도록 하므로 발광다이오드(LED1)(LED2)(LED3)(LED4)의 점등이 선택적으로 이루어 질수있고, 선풍기모터(30)나 선풍기망(70)에 직접 고정할 수도 있다.In addition, the fixture for installing the permanent magnet (N) (S) may be composed of a nut 80 for connecting the fan network 70 and the fan motor 30, but is not necessarily limited to such a fixture, Since the permanent magnet (N) (S) is attached to the metal mesh by magnetic force, so that detachment is possible, the lighting of the light emitting diodes (LED1) (LED2) (LED3) (LED4) can be selectively made, the fan motor (30) Or directly to the fan network 70.

즉, 필요에 따라 발광다이오드(LED1)(LED2)(LED3)(LED4)가 점등되지 않게 하거나 또는 점등되도록 할 수 있게 되는 것이다.That is, the light emitting diodes LED1, LED2, LED3, and LED4 may be turned off or turned on as necessary.

그리고, 첨부도면 도2에 도시된 바와 같이 발광다이오드(LED1)(LED2)(LED3)(LED4)를 일직선상에 배치하지 않고, 회전방향으로 일정한 각도로 등분할하여 배치할 수 있으며, 예들 들어서 발광다이오드(LED1)(LED2)(LED3)(LED4)가 4개인 경우 분할각도는 90°이다. (각 실시예에서 동일한 부분에 대해서는 동일부호를 사용하였음.)As shown in FIG. 2, the light emitting diodes LED1, LED2, LED3, and LED4 may be arranged in equal parts at a predetermined angle in the rotational direction, instead of being disposed in a straight line. When there are four diodes LED1, LED2, LED3 and LED4, the dividing angle is 90 °. (The same reference numerals are used for the same parts in each example.)

한편, 첨부도면 도3에 도시된 바와 같이 상기 발광다이오드(LED5)(LED6)는 광축이 선풍기날개(40)의 표면을 향하도록 상기 콘(42)의 외주면에 축의 직각방향으로 돌출되도록 설치하고, 그 선풍기날개(40)의 표면에는 발광다이오드(LED5)(LED6)로부터 방사된 빛을 전방 측으로 반사시키기 위한 반사시트(60)(62)를 설치하였으며, 코일(52)(54)도 각각의 발광다이오드(LED5)(LED6)에 대응하도록 설치할 수 있으며, 회전시 편심에 의한 진동을 방지하기 위해 코일(52)(54)을 대칭형태로 여러개 설치할 수 있다. (각 실시예에서 동일한 부분에 대해서는 동일부호를 사용하였음.)On the other hand, as shown in Figure 3, the light emitting diodes (LED5) (LED6) is installed so as to project in a direction perpendicular to the axis on the outer peripheral surface of the cone 42 so that the optical axis toward the surface of the fan blade (40), On the surface of the fan blade 40, reflecting sheets 60 and 62 were installed to reflect the light emitted from the light emitting diodes LED5 and LED6 to the front side, and the coils 52 and 54 also emitted respective light. It can be installed so as to correspond to the diode (LED5) (LED6), and in order to prevent the vibration caused by the eccentricity during rotation can be provided with a plurality of coils 52, 54 in a symmetrical form. (The same reference numerals are used for the same parts in each example.)

여기서 발광다이오드(LED5)(LED6)는 선풍기날개(40)의 개수에 대응하도록 설치될 수 있다.The light emitting diodes LED5 and LED6 may be installed to correspond to the number of fan blades 40.

도면중 미설명 부호 35는 모터축을 나타낸 것이며, 37은 콘(42)을 모터축(35)에 고정하기 위한 캡너트를 나타낸 것이다.In the figure, reference numeral 35 denotes a motor shaft, and 37 denotes a cap nut for fixing the cone 42 to the motor shaft 35.

이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1 및 도2에 도시된 바와 같이 선풍기모터(30)의 모터축(35)이 회전되면, 이 모터축(35)에 연결되어 있는 선풍기날개(40)를 비롯하여 콘(42)에 설치되어 있는 코일(50)과 발광다이오드(LED1)(LED2)(LED3)(LED4)가 함께 회전되는데, 이때 영구자석(N)(S)은 선풍기모터(30)의 고정자(32)와 함께 고정체에 고정되어 있고, 코일(50)은 이 영구자석(N)(S)과 근접된 상태에서 선풍기날개(40)의 회전력에 의해 고속으로 회전되기 때문에 전자기유도에 의해 코일(50)에 전류가 흐르게 된다.As shown in FIGS. 1 and 2, when the motor shaft 35 of the fan motor 30 is rotated, the fan shaft 40 connected to the motor shaft 35 is installed on the cone 42. The coil 50 and the light emitting diodes LED1, LED2, LED3, and LED4 rotate together, and the permanent magnets N are fixed together with the stator 32 of the fan motor 30. The coil 50 is rotated at a high speed by the rotational force of the fan blade 40 in the state adjacent to the permanent magnet (N) (S), so that current flows in the coil 50 by electromagnetic induction. do.

이때 코일(50)에서 발생되는 전류는 발광다이오드(LED1)(LED2)(LED3)(LED4)를 통해 소비되면서 발광다이오드(LED1)(LED2)(LED3)(LED4)를 점등시키게 되고, 점등된 발광다이오드(LED1)(LED2)(LED3)(LED4)는 선풍기날개(40) 및 콘(42)과 함께 고속으로 회전되고 있기 때문에 이를 보는 사람은 잔상에 의해 발광다이오드(LED1)(LED2)(LED3)(LED4)가 지나간 궤적이 마치 링모양의 점등패턴을 이루는 것처럼 착시를 일으키게 된다.At this time, the current generated in the coil 50 is consumed through the light emitting diodes LED1, LED2, LED3, and LED4 to light up the light emitting diodes LED1, LED2, LED3, and LED4. Since the diodes (LED1) (LED2) (LED3) (LED4) are being rotated together with the fan blades 40 and the cone 42 at high speed, the viewer sees the light emitting diodes (LED1) (LED2) (LED3) The trajectory of (LED4) passing through causes optical illusion as if it forms a ring-shaped lighting pattern.

즉, 영구자석(N)(S)과 코일(50)은 교류발전기의 역할을 하게 되고, 발광다이오드(LED1)(LED2)(LED3)(LED4)는 정류다이오드와 전등의 역할을 하게 되어 코일(50)로부터 흐르게 되는 정현파(正弦波)모양의 전류는 발광다이오드(LED1)(LED2)(LED3)(LED4)에 의해 반파정류되어 발광다이오드(LED1)(LED2)(LED3)(LED4)의 순방향으로 전류가 흐를 때만 점등되고, 그 반대방향으로 흐를 때는 소등상태를 유지하게 되며, 이러한 주기가 매우 빠른 속도로 전환되기 때문에 발광다이오드(LED1) (LED2)(LED3)(LED4)는 매우 빠른 속도로 점멸되어 육안으로는 이를 포착하지 못하고 발광다이오드(LED1)(LED2)(LED3)(LED4)가 항상 점등되어 있는 것처럼 느끼게 된다.That is, the permanent magnet (N) (S) and the coil 50 acts as an alternator, and the light emitting diodes (LED1) (LED2) (LED3) (LED4) acts as a rectifier diode and a lamp to the coil ( The sinusoidal current flowing from the 50 is half-wave rectified by the light emitting diodes LED1, LED2, LED3, and LED4, and forwards to the light emitting diodes LED1, LED2, LED3, and LED4. It only turns on when the current flows and stays off when it flows in the opposite direction, and the light-emitting diodes (LED1) (LED2) (LED3) (LED4) blink at a very high speed because these cycles are switched at a very high speed. This makes it impossible for the naked eye to capture this, and it feels as if the light emitting diodes LED1, LED2, LED3, and LED4 are always lit.

또한, 발광다이오드(LED1)(LED2)(LED3)(LED4)가 각기 다른 색으로 구성된 경우에는 다양한 컬러를 볼 수 있게 되어 보는 이에게 색에 대한 아름다움과 즐거움을 제공해 주게 된다.In addition, when the light emitting diodes LED1, LED2, LED3, and LED4 are configured with different colors, various colors can be seen, thereby providing beauty and fun to the viewer.

한편, 첨부도면 도3에 도시된 바와 같이 발광다이오드(LED5)(LED6)가 선풍기 날개(40)를 향해 방사상으로 설치된 경우에는 발광다이오드(LED5)(LED6)로부터 방사된 빛이 선풍기날개(40)의 표면에 부착되어 있는 반사시트(60)(62)에 의해 반사되어 전방측을 향해 광로가 변경되어 전방측에 위치된 사람이 마치 선풍기날개(40)에 점광원이 있는 것처럼 착각을 일으키게 된다.On the other hand, when the light emitting diodes (LED5) (LED6) is radially installed toward the fan blade 40, as shown in Figure 3 attached to the fan blades 40, the light emitted from the light emitting diodes (LED5) (LED6) Reflected by the reflective sheets 60, 62 attached to the surface of the light path is changed toward the front side, the person located in the front side will be mistaken as if there is a point light source on the fan blade (40).

또, 코일(52)(54)이 중심에서 대칭을 이루도록 설치된 경우에는 무게 밸런스를 유지하게 되어 회전 중에 발생될 수 있는 진동을 억제하게 된다.In addition, when the coils 52 and 54 are installed to be symmetrical in the center, the weight balance is maintained to suppress vibrations that may occur during rotation.

이상에서 설명한 바와 같은 본 발명은 선풍기날개가 회전될 때 발광다이오드가 이 선풍기날개와 함께 회전되면서 링형태의 점등패턴을 형성하도록 구성되어 있기 때문에 사용자에게 시각적인 아름다움과 즐거움을 제공해줄 수 있는 효과가 있으며, 필요에 따라 선택적으로 자석을 착탈하므로 점등과 소등을 설정할 수 있게 되고, 타제품과의 차별화로 인해 제품의 구매욕구를 향상시킬 수 있는 것은 물론이고, 제품에 대한 경쟁력을 크게 향상시킬 수 있는 효과가 있다.As described above, the present invention is configured to form a ring-shaped lighting pattern while the light emitting diode is rotated together with the fan blade when the fan blade is rotated, thereby providing visual beauty and enjoyment to the user. In addition, the magnet can be selectively turned on and off as needed to turn on and off the lights, and the product's purchase desire can be improved due to differentiation from other products, and the competitiveness of the product can be greatly improved. There is.

또한, 자체의 발전력으로 발광다이오드를 점등시키기 위한 전력을 얻을 수 있도록 구성되어 있기 때문에 전력을 공급하기 위한 구성이 간소화되는 효과가 있다.In addition, since it is configured to obtain power for turning on the light emitting diode with its own power generation, there is an effect of simplifying the configuration for supplying power.
