Description

전자제품 발광장치Electronic light emitting device

본 발명은 전자제품 발광장치에 관한 것으로서 특히, 발광체를 감싸고 있는 홀더(Holder)에 반사면을 설치하고, 상기 반사면을 사용자가 발광되는 빛을 인식하기에 최적의 각도인 42°31′이 되게 계단식으로 변형하여 사용자가 어느각도에서 발광장치를 보든지 명확하고 뚜렷히 보일 수 있도록 한 전자제품 발광장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic light emitting device, and in particular, a reflection surface is provided in a holder surrounding a light emitting body, and the reflection surface is 42 ° 31 'which is an optimal angle for a user to recognize emitted light. The present invention relates to an electronic light emitting device which can be clearly and clearly seen in a stepwise transformation so that a user sees the light emitting device at any angle.

일반적으로 전자제품의 발광장치라 하면, 제품의 버튼(Button) 부위가 어두운 곳이나 야간에 명확히 보이지 않는곳 등에 설치되어 사용자가 신속하고 정확하게 제품의 기능동작을 실행할 수 있도록 부착설치되어 있음은 이미 공지된 사실이다.In general, the light emitting device of an electronic product is already known that the button part of the product is installed in a dark place or a place that is not clearly visible at night, so that the user can quickly and accurately execute the function operation of the product. It is true.

또한, 일반적으로 발광체를 감싸고 있는 홀더는 그 재질의 대부분이 아크릴(Acryl) 수지로 구성되어 사용되고 있다.In addition, in general, the holder surrounding the light emitting body is mostly made of acrylic (Acryl) resin.

종래에는 도 1에서 보는 바와같이 아크릴(Acryl) 수지로 형성된 홀더(2)를 실크스크린인쇄(3)하여 사용자가 가시부(4)를 통하여 단순히 발광체(1)로 부터 발광되어 진행중인 빛을 식별하도록 하였다.Conventionally, as shown in FIG. 1, a silk screen printing 3 of a holder 2 formed of an acrylic resin is performed to allow a user to simply identify light that is being emitted from the light emitter 1 through the visible part 4. It was.

상기와 같은 종래의 빛 식별방법은 사용자의 위치와 보는 각도에 따라 빛의 밝기와 명확도가 변동하여 사용자가 제품을 동작시키기 위하여 버튼부위를 찾는 경우등과 같은 경우에 어둡거나 흐려서 정확하게 제품의 동작기능을 수행할 수가 없는 문제점이 있었다.In the conventional light identification method as described above, the brightness and clarity of the light vary according to the position and viewing angle of the user, so that the user can operate the product accurately in a dark or blurred case such as when the user looks for a button to operate the product. There was a problem that the function can not be performed.

본 발명은 상기와 같은 문제점을 개선하기 위하여 안출된 것으로서, 발광체를 감싸고 있는 홀더(Holder)에 반사면을 설치하고, 상기 반사면은 사용자가 인식하기에 좋은 동시에 최적의 각도인 42°31′의 각도로 꺽어지게 계단식으로 형성한 것으로서 이하, 첨부한 도면에 의거하여 본 발명을 상세히 설명하면 다음과 같다.The present invention has been made to solve the above problems, the reflection surface is installed in the holder (Holder) surrounding the light emitting body, the reflection surface is good for the user and at the same angle of 42 ° 31 ' The present invention will be described below in detail with reference to the accompanying drawings, which are formed stepwise at an angle.

도 2 내지 도 4에서 보는 바와같이 발광체(11)로 부터 발광되는 빛을 반사할 수 있고, 재질은 아크릴(Acryl) 수지로 형성된 홀더(Holder)(12)와, 상기 홀더(12)에 설치되어 발광체(11)로 부터 발광되는 빛을 사용자가 인식하기에 좋은 최적은 각도인 42°31′으로 반사시킬 수 있는 계단식으로 형성된 반사면(13)으로 형성된 것이다.As shown in FIGS. 2 to 4, the light emitted from the light emitter 11 may be reflected, and the material may be formed in a holder 12 formed of an acrylic resin, and installed in the holder 12. The most suitable for the user to recognize the light emitted from the light emitter 11 is formed by a stepped reflective surface 13 that can reflect at an angle of 42 ° 31 '.

여기서, 42°13′이라는 수치는 빛이 공기에 접촉하여 빛이 굴절하는 양을 빛이 아크릴(Acryl)에 접촉하여 빛이 굴절하는 양으로 나눈다음 Sin90°를 곱하면 되는 것이다.Here, the value of 42 ° 13 'is obtained by dividing the amount of light refracted by contacting air with the amount of light refracting by contacting acryl and then multiplying Sin90 °.

이를 식으로 나타내면If you express this as

빛이 공기에 접촉했을때 빛의 굴절률 : 1.00029Refractive Index of Light when Light Contacted Air: 1.00029

빛이 아크릴(Acryl)에 접촉했을때 빛의 굴절률 : 1.480Refractive Index of Light when Light Contacted Acrylic: 1.480

이 되는 것이다.It will be.

상기와 같은 수식에 의하여 계산된 42°31′의 수치는 홀더(12)의 재질이 아크릴(Acryl) 수지가 아닌 경우에는 수치의 변화가 있을 수 있다.The 42 ° 31 'value calculated by the above equation may be changed when the material of the holder 12 is not an acrylic resin.

또한, 반사면(13) 사이에 있는 간격부(13a),(13b)의 폭이 작으면 작을수록 빛의 전반사가 이루어지며 간격부(13a),(13b)의 폭이 작지않으면 전반사가 이루어지지 않는데 그 간격은 최대 0.3mm 이하라야 하는 것이다.In addition, the smaller the width of the gaps 13a and 13b between the reflective surfaces 13 is, the total reflection of light occurs. If the widths of the gaps 13a and 13b are not small, total reflection is not achieved. The gap should be less than 0.3mm.

상기와 같이 구성된 본 고안의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

제품의 동작을 실행시키기 위하여 전원을 온시키면 상기 전원의 신호가 발광체(11)에 전달하게 되어 발광체(11)가 발광하게 되고, 상기 발광된 빛이 홀더(12)에 설치되어 있는 42°31′으로 꺽이고 계단식으로 형성된 반사면(13)에 의하여 A방향으로 입사하여 진행하던 빛이 B방향으로 전반사되는 것이다.When the power is turned on to execute the operation of the product, the signal of the power is transmitted to the light emitting body 11 so that the light emitting body 11 emits light, and the emitted light is 42 ° 31 'installed in the holder 12. The light that has entered and traveled in the A direction is totally reflected in the B direction by the reflective surface 13 which is bent and cascaded.

여기서, 42°31′의 각도로 꺽인 반사면을 계단식으로 설치한 이유는 상기 홀더(12)가 아크릴(Acryl) 수지로 형성되어 있어서 아크릴을 42°31′의 각도로 성형가공할때 아크릴 자체에서 수축이 발생하여 최적의 각도인 42°31′의 각도에 도달하지 못하기 때문에 이것을 감안하여 계단식으로 반사면(13)을 설치하여 수축을 방지하였는데 상기 반사면(13)에 있는 간격부(13a),(13b)의 간격이 작으면 작을수록 빛의 전반사가 일어나게 되는 것이다.Here, the reason why the reflective surface bent at an angle of 42 ° 31 'is provided in a stepwise manner is that the holder 12 is formed of an acrylic resin, and thus the acrylic itself is formed when the acrylic is molded at an angle of 42 ° 31'. Since the shrinkage occurred and the optimum angle was not reached, the angle of 42 ° 31 'was set in consideration of this to prevent the shrinkage by installing the reflective surface 13 step by step. The gap 13a in the reflective surface 13 was prevented. The smaller the interval of, 13b is, the total reflection of light occurs.

이상에서 상술한 바와같이 본 발명에 의하면 발광체를 감싸고 있는 홀더에 반사면을 42°31′의 각도로 설치하는 동시에 계단식으로 형성하여 사용자의 위치와 보는 각도에 관계없이 발광장치를 신속하며, 정확히 식별할 수 있는 동시에 빛밝기를 균일하게 유지시키고 광원을 효율적으로 활용할 수 있는 효과를 나타낸다.As described above, according to the present invention, the reflective surface is installed on the holder enclosing the light emitting body at an angle of 42 ° 31 'and is formed stepwise to quickly and accurately identify the light emitting device regardless of the user's position and viewing angle. At the same time, it maintains the light brightness uniformly and effectively utilizes the light source.
