* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 리모콘 본체 2, 2' : 발광다이오드1: Remote controller main body 2, 2 ': light emitting diode

3 : 윈도우 펠트 3' : 요입면3: window felt 3 ': recessed surface

4 : 지지판 5 : 반사판4: supporting plate 5: reflecting plate

5' : 요입면 6 : 반사벽5 ': recessed surface 6: reflective wall

본 고안은 리모콘의 윈도우 펠트 구조에 관한 것으로, 특히 윈도우 펠트의 내면에 반구형상 요입면을 형성하여 리모콘에서 발사되는 적외선의 발사각도를 180°범위까지 확산시킬 수 있게한 윈도우 펠트 구조에 관한 것이다.The present invention relates to a window felt structure of the remote control, and more particularly, to a window felt structure that can form a hemispherical concave indentation on the inner surface of the window felt to diffuse the firing angle of the infrared ray emitted from the remote control to a 180 ° range.

텔레비젼 수상기를 포함한 각종 전자제품을 원격제어하기 위해 사용되는 종래 리모콘은 통상 제1(a)도 제1(b)도에 도시한 바와 같이, 본체(11)의 내부기판(12)에 설치한 발광다이오드(13)(13')에서 소정의 잡동놉(도시되지 않음)을 누름에 따라 방출된 빛이 본체(11)의 일측단부에 부착고정된 윈도우 펠트(14)를 통하여 외부로 발산되도록 되어 있는바, 이와 같은 종래의 리모콘은 발광다이오드(13)(13')에서 방출된 적외선이 30°각의 범위에서 발사되어지므로, 사용자가 전자제품을 원격제어할 수 있는 발사각 30°의 범위에서 움직여야 하고, 각도를 맞추기 위하여 여러번 작동을 해보아야 하는 등의 불편함이 있었다.Conventional remote controllers used to remotely control various electronic products including television receivers generally emit light provided on the internal substrate 12 of the main body 11, as shown in Figs. 1 (a) and 1 (b). The light emitted by pressing a predetermined operation knob (not shown) from the diodes 13 and 13 'is to be emitted to the outside through the window felt 14 fixed to one end of the main body 11. Bar, such a conventional remote control is because the infrared light emitted from the light emitting diodes 13, 13 'is emitted in a range of 30 degrees, so that the user must move in a range of 30 degrees of launch angle to remotely control the electronics There were inconveniences such as having to operate several times to adjust the angle.

본 고안은 이와 같은 종래의 문제점을 해소하기 위하여 적외선 투광창 역할을 하는 윈도우 펠트의 내면에 반구형성 요입면을 형성하여 적외선이 발산각 범위를 확대시키고, 내부에 반사판을 설치하여 적외선이 윈도우 펠트를 통하지 않고는 외부로 방출되지 못하게 함으로써 적외선이 방출효율을 증가할 수 있게한 것인바, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention forms a hemispherical concave indentation surface on the inner surface of the window felt that serves as an infrared light emitting window to solve such a conventional problem, and the infrared rays extend the divergence angle range, and the infrared reflecting window felt Infrared radiation to increase the emission efficiency by preventing the emission to the outside without passing through, as described in detail by the accompanying drawings as follows.

제2(a)도 제2(b)도에 도시한 바와 같이 리모콘 본체(1)의 내부에 발광다이오드(2)(2')가 설치되고 본체(1)의 일측단부에는 발광다이오드(2)(2')에서 방출되는 적외선이 발산되는 윈도우 펠트(3)가 형성된 것에 있어서, 본체(1)의 내부 일측부에 지지판(4)을 고정하여 그 지지판(4)에 발광다이오드(2)(2')를 고정하고, 윈도우 펠트(3)의 내면에는 다수개의 반구형상 요입면(3')을 형성하는 동시에 지지판(4)의 외면에는 다수개의 반구형상 요입면(5')이 형성된 반사판(5)을 고정하고 반사판(5)의 둘레 가장자리와 윈도우펠트(3)의 둘레 가장자리간에는 반사벽(6)을 형성한 것으로, 도면 중 미설명 부호 7은 발광다이오드(2)(2')가 배설되는 인쇄회로 기판을 보인 것이다.As shown in FIG. 2 (a) and FIG. 2 (b), the light emitting diodes 2 and 2 'are provided inside the remote controller main body 1, and the light emitting diodes 2 are provided at one end of the main body 1, respectively. In the window felt (3) in which infrared rays emitted from (2 ') are emitted, the support plate (4) is fixed to one inner side of the main body (1), and the light emitting diodes (2) (2) are supported on the support plate (4). ') Is fixed, a plurality of hemispherical recesses 3' are formed on the inner surface of the window felt 3, and at the same time, a reflecting plate 5 having a plurality of hemispherical recesses 5 'is formed on the outer surface of the support plate 4; ) And a reflective wall 6 is formed between the circumferential edge of the reflector 5 and the circumferential edge of the window felt 3. In the drawing, reference numeral 7 denotes the light emitting diodes 2 and 2 ′. The printed circuit board is shown.

이와 같이 된 본 고안의 작용효과는 다음과 같다.The effect of the present invention thus obtained is as follows.

전자제품을 제어하기 위하여 리모콘의 작동놉을 눌러 발광다이오드(2)(2')로부터 적외선이 방출되는 경우에는 제2(a)도 제2(b)도에 도시한 바와 같이 적외선이 발광다이오드(2)(2')에서 30°각으로 방출되고 그 방출된 빛이 윈도우 펠트(3)의 방구형상 요입면(3')에 입사되어 그 요입면(3')에서 반사되어지므로 윈도우펠트(3)의 외부로 발사되는 적외선은 180°각까지 확산되어 발사될 수 있다. 한편 윈도우펠트(3)의 내부 발광다이오드(2)(2')가 고정된 지지판(4)에는 반사판(5)이 형성되고 그 반사판(5)과 윈도우 펠트(3)사이에는 반사벽(6)이 형성되어 윈도우 펠트(3)를 통하지 않고 외부로 방출되는 적외선을 차단하게 된다.When infrared rays are emitted from the light emitting diodes 2 and 2 'by pressing the operating knob of the remote controller to control the electronics, the infrared light is emitted from the light emitting diodes as shown in FIGS. 2) the light is emitted at a 30 ° angle at 2 'and the emitted light is incident on the far-end recessed surface 3' of the window felt 3 and reflected at the recessed surface 3 '. The infrared rays emitted to the outside may be diffused up to a 180 ° angle. On the other hand, a reflecting plate 5 is formed on the supporting plate 4 to which the internal light emitting diodes 2, 2 ′ of the window felt 3 are fixed, and a reflecting wall 6 between the reflecting plate 5 and the window felt 3. This is formed to block the infrared radiation emitted to the outside without passing through the window felt (3).

상기와 같은 본 고안은 리모콘에서 발사되는 적외선을 180°범위에서 확산되어 발사될 수 있게함으로써 리모콘 작동범위가 넓어지므로 발사각 30°범위내에서만 작동가능한 종래의 불편함을 배제하는 이점이 있고, 지지판과 윈도우펠트사이에 형성된 반사판과 반사벽에서 외부로 방출되는 적외선이 차단되므로 적외선 발산효율이 높은 이점이 있다.The present invention as described above has the advantage of eliminating the conventional inconvenience that can be operated only within the 30 ° range of the launch angle because the operating range of the remote control is widened by allowing the infrared rays emitted from the remote control to be diffused in the 180 ° range, and the support plate and Since infrared rays emitted to the outside from the reflective plate and the reflective wall formed between the window felt is blocked, there is an advantage of high infrared radiation efficiency.
