本考案は、光源にLEDを採用し、光源からの信号光を拡散して周囲に投光す るようにした信号報知表示灯に関する。 This invention uses an LED as a light source, diffuses the signal light from the light source, and projects it into the surrounding area. This invention relates to a signal notification indicator lamp.
【0002】0002
光源にLEDを採用した信号報知表示灯は、多くの種類が市場に提供されてき ており、構造的にもいろいろな工夫が凝らされている。これはLEDを光源に採 用すれば、電球交換が不要で、振動等の要因にも強いことによる。そこで、従来 の白熱球光源からLED光源への変更が模索されているのである。 There are many types of signal notification indicators that use LEDs as the light source on the market. It has been designed with a variety of innovations in its structure. This uses LED as the light source. If used, there is no need to replace light bulbs and it is resistant to factors such as vibration. Therefore, conventionally A change from an incandescent bulb light source to an LED light source is being explored.
【0003】 ところが、LEDは光量が少ないためにこれを補う工夫が必要になる。その工 夫として、使用LED個数を増やす、集光型LEDを使用して輝度を向上させる 、または、各種レンズを用いて光を拡散させて光源大きさを大きくする、等の手 段を単独、あるいは組合わせて使用していた。0003 However, since LEDs emit only a small amount of light, it is necessary to devise ways to compensate for this. That work As a husband, increase the number of LEDs used and use condensing LEDs to improve brightness. , or use various lenses to diffuse the light and increase the size of the light source. Stages were used singly or in combination.
【0004】 従来例として、実用新案出願公開昭和62年78770号がある。この構成は LEDを外周方向へ立設し、鼓状反射部によって光源光を増幅させようとしたも のである。このように、従来、LEDを単純に外周へ向けて設置することが普通 に用いられていた。LED単体を外周へ向けて設置すると看者には点状の光源が 視認される。この実施例では鼓状反射部で光源光を反射投光しているから看者に は線状の光源が視認される。視認範囲を広くするためや、鼓状反射部で光源光を 反射投光するためには拡散型のLEDを使用する。この欠点として、距離をおい て信号報知表示灯を視認するときに信号光が拡散されてしまい、遠方からの視認 性に劣る問題があった。0004 A conventional example is Utility Model Application Publication No. 78770 of 1988. This configuration is An attempt was made to erect LEDs toward the outer periphery and amplify the light source light using a drum-shaped reflective section. It is. In this way, conventionally, it was common to simply install LEDs facing the outer periphery. It was used in When a single LED is installed facing toward the outer periphery, a point-like light source appears to the viewer. Visible. In this embodiment, the light source light is reflected and projected by the drum-shaped reflection part, so it is not visible to the viewer. A linear light source is visible. To widen the visibility range, or to reflect the light source with a drum-shaped reflective part. A diffused type LED is used for reflected light projection. The disadvantage of this is that you need to keep your distance. When visually checking the signal notification indicator lamp, the signal light will be diffused and it will be difficult to see it from a distance. There was a problem with gender.
【0005】 他の従来例として、実用新案出願公開昭和63年176214号があり、信号 光をLEDの反射光にて得ようとしている。構成としては、鼓状の回転放物面反 射鏡の焦点位置にLEDを保持して成る。しかしながら、この構成も回転放物面 反射鏡の反射投光を利用するために拡散型のLEDを使用する。従って、遠方か らの視認性に劣る問題がある。また、視認される光源も線状の光源となる。これ に加えて、LEDを反射面から離して設けると表示灯全体として大きくなり、L EDを反射面の近傍に設けると鼓状の回転放物面反射鏡の曲面が大きくなるので 回転放物面反射鏡の周方向を大きくするか、回転放物面反射鏡の周方向を小さく して反射効率を下げるかを選択する必要がある。いずれにしても信号灯全体とし て大きくなる問題があった。[0005] Another conventional example is Utility Model Application Publication No. 176214 of 1988, which is a signal We are trying to obtain light from the reflected light of the LED. The composition is a drum-shaped paraboloid of revolution. It consists of an LED held at the focal point of a projecting mirror. However, this configuration is also a paraboloid of revolution. A diffused type LED is used to utilize the reflected light from the reflecting mirror. Therefore, is it far away? There is a problem with poor visibility. Furthermore, the visually recognized light source is also a linear light source. this In addition, if the LED is placed away from the reflective surface, the indicator light will become larger as a whole, and the L If the ED is installed near the reflecting surface, the curved surface of the drum-shaped paraboloid of revolution will become larger. Increase the circumferential direction of the paraboloid of revolution reflector, or reduce the circumferential direction of the paraboloid of revolution reflector. It is necessary to choose whether to lower the reflection efficiency by In any case, the entire signal light There was a growing problem.
【0006】 また、LEDには投光の方向性があるので、製造過程や使用中にLEDの投光 軸が振動等で変動すると、投光性能が低下し、信号報知機能の障害のひとつとし て指摘されていた。[0006] In addition, since LEDs have a directionality of light emission, it is important to note that during the manufacturing process and use, If the axis fluctuates due to vibration etc., the light projection performance will deteriorate and this can be a problem in the signal notification function. It was pointed out that

解決しようとする問題点は、信号報知表示灯を構成するにあたって視認される 光源大きさを大きくするとともに、信号光の拡散を小さくして遠方からの視認性 を向上させ、且つ小型の信号報知表示灯を提供せんとするものである。 The problem to be solved is visible when configuring the signal notification indicator. Increased light source size and reduced signal light dispersion to improve visibility from a distance It is an object of the present invention to provide a small-sized signal notification indicator lamp.
【0008】 また、LED、およびLEDを配設した基板の保護と、あわせてLEDを保持 することで投光軸の変動を防止して投光性能の維持を目的とする。[0008] In addition, it protects the LED and the board on which the LED is installed, and also holds the LED. The purpose of this is to prevent fluctuations in the light projection axis and maintain light projection performance.

【0015】 次に、第2図の投光状態の説明図と、第5図の光源の視認状態を示す説明図に 従ってLEDの投光状態、看者からの視認状態について説明する。[0015] Next, we will refer to the explanatory diagram of the light projection state in Fig. 2 and the explanatory diagram showing the visible state of the light source in Fig. 5. Therefore, the light emitting state of the LED and the visual recognition state from the viewer will be explained.
【0016】 まず、 LED1、1は、上下に対向配列されている。この信号光6をそのま まで視認すると大きい点状の光源として視認される。LEDが多数個ある場合、 多数の大きい点状の光源が視認されることとなる。[0016] First, the LEDs 1, 1 are arranged vertically facing each other. This signal light 6 is When visually recognized up to this point, it appears as a large point-like light source. If there are many LEDs, Many large point-like light sources will be visible.
【0017】 そして、信号光6は反射面31で周方向に反射投光される。反射面31は平面 ではなく、曲面のため信号光6は周方向に拡散されて投光されることとなる。L EDが多数個ある場合、縦長い線状の光源が横並びに多数視認される。[0017] Then, the signal light 6 is reflected and projected in the circumferential direction by the reflecting surface 31. The reflective surface 31 is a flat surface Rather, because of the curved surface, the signal light 6 is diffused in the circumferential direction and projected. L When there are a large number of EDs, a large number of vertically long linear light sources are visually recognized side by side.
【0018】 最後に、信号光6はグローブ4の拡散性レンズ41を透過して着色投光され、 このとき拡散性レンズ41によって更に横方向に拡散分光される。その結果、多 数個のLED光源を使用する本考案の信号報知表示灯にあっては、看者は面状の 光源として信号光6の集合を視認することとなる。更に、LED光は上下から反 射面31の上面側、下面側に反射投光して周方向に投光されるので、光源の視認 大きさは縦方向に2倍となる。第2図において、看者からみた光源は、仮想光源 11の位置にあることとなり、仮想光源11、11と、グローブ4の拡散性レン ズ41間の距離を長く確保できた。これによって、従来のLED式信号報知表示 灯のように光源が点状でなく、面状に視認できるので信号表示の視認性が向上し た。[0018] Finally, the signal light 6 passes through the diffusive lens 41 of the globe 4 and is colored and projected. At this time, the light is further diffused in the horizontal direction by the diffusive lens 41. As a result, many In the signal notification indicator lamp of the present invention, which uses several LED light sources, the viewer can A collection of signal lights 6 is visually recognized as a light source. Furthermore, the LED light is reflected from above and below. The light is reflected on the upper and lower sides of the projection surface 31 and projected in the circumferential direction, making it easy to visually recognize the light source. The size is doubled in the vertical direction. In Figure 2, the light source seen from the viewer is a virtual light source. 11, and the virtual light sources 11 and 11 and the diffusive lens of the globe 4 We were able to secure a long distance between the 41 zones. As a result, the conventional LED signal notification display The visibility of the signal display is improved because the light source can be seen as a surface rather than a point like a lamp. Ta.
