Description

表示器display

　本発明は主に自動車などの移動体に取り付けられて、移動方向を表示する方向指示器(turn signal又はdirectional indicator)、及び後続車に注意を促すハザードランプ(warning light)の機能を果たす表示器に関する。 The present invention is mainly attached to a moving body such as an automobile, and displays a direction indicator (turn signal or directional indicator) that displays a moving direction, and a function that functions as a hazard lamp (warning light) that alerts the following vehicle. About.

　従来より、自動車及び自動二輪車には、橙色の点滅する電球が左右に設けられており、左右いずれか一方を点滅させることにより周囲に方向を伝える方向指示器として用いられるとともに、両方を点滅させることにより、周囲に危険を伝えるハザードランプとして用いられる表示器が取り付けられている。 Conventionally, automobiles and motorcycles have been provided with orange flashing light bulbs on the left and right, which can be used as a direction indicator to convey the direction to the surroundings by flashing either the left or right, and both flash Therefore, an indicator used as a hazard lamp for transmitting danger to the surroundings is attached.

　近年では上述のような表示器において、消費電力を減らすことができ、デザインの自由度が高い等の理由から電球に代えて複数のＬＥＤ（Light Emitting Diode）を光源とする表示器が知られている。このような表示器の光源となるＬＥＤは指向性が高く、また、このような表示器の中には、極めて多数のＬＥＤを配置するものもあることから、点滅するこの表示器を見た場合に、不能グレア(Blinding glare)、減能グレア(Disability glare)、又は不快グレア(Discomfort glare)が発生する問題があった。そこで、特に近年ではＬＥＤの指向性の高さから発生する不快グレア等の問題を解決するために、拡散性を高めたリフレクタ(Reflector)を用いた表示器が種々提案されている（例えば特許文献１）。 In recent years, there has been known a display using a plurality of LEDs (Light Emitting Diode) as a light source instead of a light bulb for the reason that power consumption can be reduced and the degree of freedom in design is high. Yes. The LED that serves as the light source for such a display has high directivity, and some of these displays have a very large number of LEDs. In addition, there is a problem that disabling glare, disability glare, or discomfort glare occurs. Therefore, in recent years, various displays using a reflector having improved diffusibility have been proposed in order to solve problems such as unpleasant glare caused by the high directivity of LEDs (for example, Patent Documents). 1).

特開２００８－０５３２３５号公報JP 2008-053235 A

　しかしＬＥＤは、熱慣性がほとんどなく電源の断続に対して応答性が高いので、方向指示器やハザードランプのように、点滅する表示器の光源として用いた場合、瞬時に点灯時と消灯時とを繰り返すため明暗の差が大きくなりグレアが発生し易い問題がある。特に、ＬＥＤを用いた表示器には多数のＬＥＤが用いられることが多く、多数のＬＥＤが同時に点灯及び消灯を繰り返すと、より明暗の差が大きくなるので、よりグレアが発生し易くなる問題がある。 However, LEDs have little thermal inertia and are highly responsive to power interruption, so when used as a light source for flashing indicators such as turn indicators and hazard lamps, Is repeated, there is a problem that the difference in brightness becomes large and glare is likely to occur. In particular, many LEDs are used in a display using LEDs, and when a large number of LEDs are turned on and off at the same time, the difference between brightness and darkness becomes larger, so there is a problem that glare is more likely to occur. is there.

　そこで、本発明は、消費電力が少なくデザインの自由度が高いＬＥＤを光源として用いた表示器であって、グレアの発生を抑え、点灯時に徐々に明るく点灯する表示器を提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a display using an LED with low power consumption and high design freedom as a light source, which suppresses the occurrence of glare and gradually lights up brightly when turned on. To do.

　上記の目的を達成するために、本発明の表示器は、移動体に取り付けられて所定の操作により点滅する表示器であって、中心から異径同心円状又は中心を同じくする異なる大きさの相似多角形状に配置される複数のＬＥＤと、該ＬＥＤの点灯及び消灯を制御する制御部と、を備え、前記制御部は、所定の操作が行われた場合に、前記ＬＥＤを中心から外周方向に順に点灯する制御を行うとともに、全てのＬＥＤが点灯した後、当該点灯した全てのＬＥＤを同時に消灯する点滅を繰り返すことを特徴としている。 In order to achieve the above object, the display device of the present invention is a display device that is attached to a moving body and blinks according to a predetermined operation, and is similar in concentric shape with different diameters from the center or of different sizes having the same center. A plurality of LEDs arranged in a polygonal shape, and a control unit that controls lighting and extinguishing of the LEDs, and the control unit, when a predetermined operation is performed, from the center to the outer peripheral direction of the LED In addition to performing control to turn on sequentially, after all the LEDs are turned on, the flashing of turning off all the turned on LEDs simultaneously is repeated.

　本発明によれば、複数のＬＥＤを中心から異径同心円状又は中心を同じくする異なる大きさの相似多角形状に配置するので、デザインに応じて様々な多角形状の表示器とすることができ、また、ＬＥＤを用いることで消費電力を少なくすることができる。そして、点灯時に中心に配置されたＬＥＤが点灯し、続いて外周方向に順に点灯するので、点灯が開始してから全てのＬＥＤが点灯するまでに時間があり、明暗差によるグレアが発生しにくい。また、このように点灯時に徐々に明るく点灯することにより、ＬＥＤと比べて熱慣性が大きい電球を用いた表示器に似た点灯をさせることができる。 According to the present invention, a plurality of LEDs are arranged in different polygonal concentric circles from the center or similar polygons of different sizes with the same center, so that various polygonal displays can be made according to the design, Moreover, power consumption can be reduced by using LEDs. And since the LED arranged at the center lights up at the time of lighting, and then lights up in order in the outer peripheral direction, there is a time from the start of lighting until all the LEDs are turned on, and glare due to light / dark difference is unlikely to occur. . In addition, by gradually illuminating brightly at the time of lighting, lighting similar to a display using a light bulb having a thermal inertia greater than that of an LED can be achieved.

　円盤状の回路基板２２の自動車に取付けたときに外側を向く面には、図２に示すように、中心に１つのＬＥＤが第１のＬＥＤ１８として配置されており、この中心のＬＥＤから等しい距離を離間させて、その外側に５個のＬＥＤが第２のＬＥＤ群１９として配置されている。そして、さらにこれらの第２のＬＥＤ群１９の外側に中心から等間隔であって、それぞれのＬＥＤの間隔も等しくなるように、１２個のＬＥＤが第３のＬＥＤ群２０として配置されている。そして、この１２個のＬＥＤの外側にも中心から等しい距離を離間させて等間隔に１２個のＬＥＤが第４のＬＥＤ群２１として配置されている。 As shown in FIG. 2, one LED is arranged at the center as the first LED 18 on the surface of the disk-shaped circuit board 22 that faces outward when mounted on the automobile, and is equal to the center LED. Are spaced apart from each other, and five LEDs are arranged as the second LED group 19 on the outside thereof. Further, twelve LEDs are arranged as the third LED group 20 on the outside of the second LED group 19 so as to be equidistant from the center and so that the intervals of the respective LEDs are also equal. The 12 LEDs are arranged as the fourth LED group 21 at equal intervals on the outside of the 12 LEDs at an equal distance from the center.

　各ＬＥＤスイッチ１４、１５、１６、１７は、ＣＰＵ１０からのコマンドにしたがって、これら第１のＬＥＤ１８、第２のＬＥＤ群１９、第３のＬＥＤ群２０、及び第４のＬＥＤ群２１に電力を供給し、又は電力を遮断するものである。カバー体２３は、第１のＬＥＤ１８、第２のＬＥＤ群１９、第３のＬＥＤ群２０、及び第４のＬＥＤ群２１を覆うように黄色半透明の樹脂により形成されている。このカバー体２３の各ＬＥＤの位置にはそれぞれ発光したＬＥＤの光を通過させて拡散させるレンズ２４が形成されている。 Each LED switch 14, 15, 16, 17 supplies power to the first LED 18, the second LED group 19, the third LED group 20, and the fourth LED group 21 in accordance with a command from the CPU 10. Or to cut off power. The cover body 23 is formed of a yellow translucent resin so as to cover the first LED 18, the second LED group 19, the third LED group 20, and the fourth LED group 21. At the position of each LED of the cover body 23, a lens 24 for allowing the emitted LED light to pass and diffuse is formed.

　なお、本表示機の周囲にはさらにテールランプ用ＬＥＤ２５が配置されており、これらのテールランプ用ＬＥＤ２５を覆うようにドーナツ状の赤色半透明の樹脂からなるテールランプ用カバー体２６が形成されており、リアコンビネーションランプ３を形成しているが、このようなテールランプ２と、方向指示器及びハザードランプとして用いる表示器１とは別体として自動車の後面にそれぞれ設けてもよい。 A tail lamp LED 25 is further arranged around the display unit, and a tail lamp cover body 26 made of a doughnut-shaped red translucent resin is formed so as to cover these tail lamp LEDs 25. Although the combination lamp 3 is formed, the tail lamp 2 and the indicator 1 used as a direction indicator and a hazard lamp may be separately provided on the rear surface of the automobile.

　次にこのような表示器１の点滅制御について、図３及び図４を参照しつつ説明する。なお、図４においては、説明を判り易くするために、図面上の発光する部分に斜線のハッチングを施している。図４（Ａ）に示すように、全てのＬＥＤ１８，１９，２０，２１が消灯された状態で、すなわち、全てのＬＥＤスイッチ１４，１５，１６，１７がＯＦＦの状態で、図示しない自動車のステアリングコラムに設けられた図示しない方向指示スイッチを例えば右折方向に作動させると、自動車の後部右側に取り付けられた表示器１に点滅操作をすべき旨の信号が送信される。そして、表示器１のＣＰＵ１０はインターフェース１３が点滅すべき旨の信号を受け取ると、ＲＡＭ１２の所定領域に設けられた点滅操作なされた旨のフラグをＯＮする。そして、ＣＰＵ１０は、図３に示すように、ＲＯＭ１１に記憶されている制御プログラムに基づいて、点滅操作がなされた旨のフラグがＯＮしているか否か判断する（Ｓ２００）。フラグがＯＮしていると判断すると（Ｓ２００：ＹＥＳ）、次に、ＣＰＵ１０は、第１のＬＥＤスイッチ１４をＯＮする処理を行う（Ｓ２０１）。第１のＬＥＤスイッチ１４がＯＮすると、図４（Ｂ）に示すように、第１のＬＥＤ１８に電源が供給され、第１のＬＥＤ１８が発光して、その光がカバー体２３のレンズ２４を通過して黄色に変換して拡散する。一方、点滅操作なされた旨のフラグがＯＦＦであると判断すると（Ｓ２００：ＮＯ）、そのまま、この処理を終了する。 Next, such blinking control of the display 1 will be described with reference to FIGS. In FIG. 4, in order to make the explanation easy to understand, hatched portions are given to light emitting portions on the drawing. As shown in FIG. 4A, in the state where all the LEDs 18, 19, 20, and 21 are turned off, that is, in the state where all the LED switches 14, 15, 16, and 17 are OFF, the steering of an automobile (not shown) When a direction indicating switch (not shown) provided in the column is actuated in a right turn direction, for example, a signal indicating that a blinking operation should be performed is transmitted to the display 1 attached to the rear right side of the automobile. When the CPU 10 of the display 1 receives a signal indicating that the interface 13 should blink, the CPU 10 turns on a flag indicating that a blinking operation is performed in a predetermined area of the RAM 12. Then, as shown in FIG. 3, the CPU 10 determines whether or not the flag indicating that the blinking operation has been performed is ON based on the control program stored in the ROM 11 (S200). If it is determined that the flag is ON (S200: YES), the CPU 10 next performs a process of turning on the first LED switch 14 (S201). When the first LED switch 14 is turned on, as shown in FIG. 4B, power is supplied to the first LED 18, the first LED 18 emits light, and the light passes through the lens 24 of the cover body 23. Then it turns yellow and diffuses. On the other hand, if it is determined that the flag indicating that the blinking operation has been performed is OFF (S200: NO), this process is terminated.

　第１のＬＥＤ１８を点灯すると（Ｓ２０１）、次に、ＣＰＵ１０は第１のＬＥＤ１８が点灯してから所定時間経過したか否か判断する（Ｓ２０２）。ここで所定時間は表示器１の所望の点滅速度から算出される時間が予め設定されており、例えば１０ミリ秒程度でよい。第１のＬＥＤ１８の点灯から所定時間経過したと判断すると（Ｓ２０２：ＹＥＳ）、次に、ＣＰＵ１０は、第２のＬＥＤ群スイッチ１５をＯＮする（Ｓ２０３）。第２のＬＥＤ群スイッチ１５がＯＮすると、図４（Ｃ）に示すように、第２のＬＥＤ群１９に電源が供給され、第２のＬＥＤ群１９が発光して、その光がカバー体２３のレンズ２４を通過して黄色に変換して拡散する。一方、第１のＬＥＤ１８の点灯から所定時間経過していないと判断すると（Ｓ２０２：ＮＯ）、所定時間経過するまで処理を待機する。 When the first LED 18 is turned on (S201), the CPU 10 next determines whether or not a predetermined time has elapsed since the first LED 18 was turned on (S202). Here, the time calculated from the desired blinking speed of the display 1 is set in advance, and may be about 10 milliseconds, for example. If it is determined that a predetermined time has elapsed since the lighting of the first LED 18 (S202: YES), the CPU 10 then turns on the second LED group switch 15 (S203). When the second LED group switch 15 is turned on, as shown in FIG. 4C, power is supplied to the second LED group 19, the second LED group 19 emits light, and the light is emitted from the cover body 23. It passes through the lens 24 and is converted into yellow and diffused. On the other hand, if it is determined that the predetermined time has not elapsed since the lighting of the first LED 18 (S202: NO), the process waits until the predetermined time elapses.

　第２のＬＥＤ群１９を点灯すると（Ｓ２０３）、次に、ＣＰＵ１０は第２のＬＥＤ群１９が点灯してから所定時間経過したか否か判断する（Ｓ２０４）。第２のＬＥＤ群１９の点灯から所定時間経過したと判断すると（Ｓ２０４：ＹＥＳ）、次に、ＣＰＵ１０は、第３のＬＥＤ群スイッチ１６をＯＮする（Ｓ２０５）。第３のＬＥＤ群スイッチ１６がＯＮすると、図４（Ｄ）に示すように、第３のＬＥＤ群２０に電源が供給され、第３のＬＥＤ１群２０が発光して、その光がカバー体２３のレンズ２４を通過して黄色に変換して拡散する。一方、第２のＬＥＤの点灯から所定時間経過していないと判断すると（Ｓ２０４：ＮＯ）、所定時間経過するまで処理を待機する。 When the second LED group 19 is turned on (S203), the CPU 10 next determines whether or not a predetermined time has elapsed since the second LED group 19 was turned on (S204). If it is determined that a predetermined time has elapsed since the lighting of the second LED group 19 (S204: YES), then the CPU 10 turns on the third LED group switch 16 (S205). When the third LED group switch 16 is turned ON, as shown in FIG. 4D, power is supplied to the third LED group 20, the third LED1 group 20 emits light, and the light is covered by the cover body 23. It passes through the lens 24 and is converted into yellow and diffused. On the other hand, if it is determined that the predetermined time has not elapsed since the lighting of the second LED (S204: NO), the process waits until the predetermined time has elapsed.

　第３のＬＥＤ群２０を点灯すると（Ｓ２０５）、次に、ＣＰＵ１０は第３のＬＥＤ群２０が点灯してから所定時間経過したか否か判断する（Ｓ２０６）。第３のＬＥＤ群２０の点灯から所定時間経過したと判断すると（Ｓ２０６：ＹＥＳ）、次に、ＣＰＵ１０は、第４のＬＥＤ群スイッチ１７をＯＮする（Ｓ２０７）。第４のＬＥＤ群スイッチ１７がＯＮすると、図４（Ｅ）に示すように、第４のＬＥＤ群２１に電源が供給され、第４のＬＥＤ群２１が発光して、その光がカバー体２３のレンズ２４を通過して黄色に変換して拡散する。一方、第３のＬＥＤの点灯から所定時間経過していないと判断すると（Ｓ２０６：ＮＯ）、所定時間経過するまで処理を待機する。 When the third LED group 20 is turned on (S205), the CPU 10 next determines whether or not a predetermined time has elapsed since the third LED group 20 was turned on (S206). If it is determined that a predetermined time has elapsed since the lighting of the third LED group 20 (S206: YES), the CPU 10 then turns on the fourth LED group switch 17 (S207). When the fourth LED group switch 17 is turned ON, as shown in FIG. 4E, power is supplied to the fourth LED group 21, the fourth LED group 21 emits light, and the light is emitted from the cover body 23. It passes through the lens 24 and is converted into yellow and diffused. On the other hand, if it is determined that the predetermined time has not elapsed since the lighting of the third LED (S206: NO), the process waits until the predetermined time elapses.

　第４のＬＥＤ群２１を点灯すると（Ｓ２０７）、次に、ＣＰＵ１０は第４のＬＥＤ群２１が点灯してから所定時間経過したか否か判断する（Ｓ２０８）。第４のＬＥＤ群２１の点灯から所定時間経過したと判断すると（Ｓ２０８：ＹＥＳ）、次に、ＣＰＵ１０は、第１のＬＥＤスイッチ１４、第２のＬＥＤ群スイッチ１５、第３のＬＥＤ群スイッチ１６、及び第４のＬＥＤ群スイッチ１７を全てＯＦＦにする処理を行う（Ｓ２０９）。全てのＬＥＤスイッチ１４，１５，１６，１７をＯＦＦにすると、図４（Ａ）に示すように、各ＬＥＤ１８，１９，２０，２１に対する電力の供給が遮断され、全てのＬＥＤ１８，１９，２０，２１が消灯する。一方、第４のＬＥＤ１７の点灯から所定時間経過していないと判断すると（Ｓ２０８：ＮＯ）、所定時間経過するまで処理を待機する。 When the fourth LED group 21 is turned on (S207), the CPU 10 next determines whether or not a predetermined time has elapsed since the fourth LED group 21 was turned on (S208). If it is determined that a predetermined time has elapsed since the fourth LED group 21 has been turned on (S208: YES), the CPU 10 then performs the first LED switch 14, the second LED group switch 15, and the third LED group switch 16. And a process of turning off all the fourth LED group switches 17 (S209). When all the LED switches 14, 15, 16, and 17 are turned OFF, as shown in FIG. 4A, the power supply to each LED 18, 19, 20, and 21 is cut off, and all the LEDs 18, 19, 20, 21 goes out. On the other hand, if it is determined that the predetermined time has not elapsed since the fourth LED 17 is turned on (S208: NO), the process waits until the predetermined time elapses.

　全てのＬＥＤ１８，１９，２０，２１を消灯すると、ステップＳ２００に処理を戻して、ＲＡＭ１２の所定領域に記憶された点滅操作がなされた旨のフラグがＯＮしているか否か判断する（Ｓ２００）。ここで、図示しないハンドル下に設けられたウインカースイッチが右折方向から戻されると、自動車の後部右側に取り付けられた表示器１に点滅操作を停止すべき旨の信号が送信される。そして、表示器１のＣＰＵ１０はインターフェース１３が点滅操作を停止すべき旨の信号を受け取ると、ＲＡＭ１２の所定領域に設けられた点滅操作なされた旨のフラグをＯＦＦする。 When all the LEDs 18, 19, 20, and 21 are turned off, the process returns to step S200, and it is determined whether or not the flag indicating that the blinking operation stored in the predetermined area of the RAM 12 is turned on (S200). Here, when the winker switch provided under the steering wheel (not shown) is returned from the right turn direction, a signal indicating that the blinking operation should be stopped is transmitted to the display 1 attached to the rear right side of the automobile. When the CPU 10 of the display 1 receives a signal indicating that the interface 13 should stop the flashing operation, the CPU 10 turns off the flag indicating that the flashing operation is performed in a predetermined area of the RAM 12.

　このように、本実施形態の表示器１は、ＬＥＤを用いることで消費電力を抑えつつ、第１のＬＥＤ１８の点灯から第２のＬＥＤ群１９、第３のＬＥＤ群２０、第４のＬＥＤ群２１の順に点灯させることで、光度を徐々に上げることができ、急激に光度を上げた場合に、当該表示器１の光を見た者の瞳孔が調節できないことにより発生するグレアを抑制することができる。また、このように点灯時に徐々に明るく点灯することにより、ＬＥＤと比べて熱慣性が大きく、従来から用いられている電球を用いた表示器１に似た点灯をさせることができる。 As described above, the display device 1 of the present embodiment uses the LEDs to suppress power consumption, and from the lighting of the first LED 18 to the second LED group 19, the third LED group 20, and the fourth LED group. By turning on the light in the order of 21, the luminous intensity can be gradually increased. When the luminous intensity is suddenly increased, glare generated due to the inability to adjust the pupil of the person who viewed the light of the display 1 is suppressed. Can do. Further, by gradually lighting up brightly at the time of lighting in this way, the thermal inertia is larger than that of the LED, and lighting similar to the display 1 using a conventionally used light bulb can be performed.

　なお、本実施形態においては、例えば、第１のＬＥＤ１８の点灯から第２のＬＥＤ群１９の点灯までの所定時間、第２のＬＥＤ群１９の点灯から第３のＬＥＤ群２０の点灯までの所定時間、第３のＬＥＤ群２０の点灯から第４のＬＥＤ群２１の点灯までの所定時間、第４のＬＥＤ群２１の点灯から全てのＬＥＤ１８，１９，２０，２１の消灯までの所定時間、及び全てのＬＥＤ１８，１９，２０，２１の消灯から第１のＬＥＤ１８の点灯までの所定時間を、それぞれ１０ミリ秒とした。このように設定すると、表示器１全体としては５０ミリ秒毎間隔で点滅することになり、一分当り１２０回点滅するので道路運送車輌法の保安基準をみたす。なお、点滅間隔はこれに限定されず道路運送車輌法の保安基準に定められた毎分６０回から１２０回をみたす点滅間隔であればよい。 In the present embodiment, for example, a predetermined time from the lighting of the first LED 18 to the lighting of the second LED group 19 and a predetermined time from the lighting of the second LED group 19 to the lighting of the third LED group 20 are used. A predetermined time from the lighting of the third LED group 20 to the lighting of the fourth LED group 21, a predetermined time from the lighting of the fourth LED group 21 to the extinguishing of all the LEDs 18, 19, 20, 21; and The predetermined time from the turn-off of all the LEDs 18, 19, 20, 21 to the turn-on of the first LED 18 was 10 milliseconds, respectively. If set in this way, the display 1 as a whole blinks at intervals of 50 milliseconds, and blinks 120 times per minute, thus satisfying the safety standards of the Road Transport Vehicle Act. Note that the blinking interval is not limited to this, and may be any blinking interval that meets 60 to 120 times per minute as defined by the safety standards of the Road Transport Vehicle Law.

　なお、本実施形態においては、第１のＬＥＤ１８、第２のＬＥＤ群１９、第３のＬＥＤ群２０、第４のＬＥＤ群２１を順に点灯する構成としたが、例えば、第１のＬＥＤ１８及び第２のＬＥＤ群１９は同時に点灯し、その後、第３のＬＥＤ群２０が点灯し、さらにその後、第４のＬＥＤ群２１が点灯するように構成してもよい。このように構成しても、表示器１全体としては、中心から順に外周方向に点灯することになり徐々に明るく点灯するので不快グレアを防ぐことができる。 In the present embodiment, the first LED 18, the second LED group 19, the third LED group 20, and the fourth LED group 21 are lit in order. For example, the first LED 18 and the second LED group 21 The second LED group 19 may be turned on at the same time, then the third LED group 20 may be turned on, and then the fourth LED group 21 may be turned on. Even if comprised in this way, since the indicator 1 whole will light in an outer peripheral direction in order from the center, and since it lights gradually brightly, an unpleasant glare can be prevented.

　また本発明の別の実施例として、図５及び図６に示すように、長方形状の回路基板２２に異なる大きさであって中心を同じくする相似形の長方形上にＬＥＤを配置してもよい。なお、図６は、説明を判り易くするために、図面上発光する部分に斜線のハッチングを施している。なお、この実施例においても、表示器１を制御する構成は、上述の実施形態のものと同様のものでよいため、制御ブロックの説明は省略する。本実施形態においては、消灯された状態から例えば図６（Ａ）に示すように、まず中心に配置された２個のＬＥＤ群に電力が供給され発光するように制御する。そして次に、図６（Ｂ）に示すように、中心の２個のＬＥＤ２７の外側に長方形状に配置されたＬＥＤ２７群に電力が供給され発光するように制御する。そして、さらに、図６（Ｃ）図６（Ｄ）に示すように、内側のＬＥＤ２７を先に点灯させ、徐々に外側に向かってＬＥＤ２７を点灯させる。このように、ＬＥＤ２７の配置は異径同心円上に限定されるものではなく、四角形その他の多角形状であってもよい。また、相似形の星型、ハート型などのように、ＬＥＤの配列を種々のデザインに構成することができる。 Further, as another embodiment of the present invention, as shown in FIGS. 5 and 6, LEDs may be arranged on a rectangular circuit board 22 on a similar rectangular shape having different sizes and the same center. . In FIG. 6, the hatched portions are hatched on the light emitting portions in the drawing for easy understanding. Also in this embodiment, the configuration for controlling the display device 1 may be the same as that of the above-described embodiment, and thus the description of the control block is omitted. In this embodiment, as shown in FIG. 6 (A), for example, control is performed so that power is supplied to two LED groups arranged at the center and light is emitted. Then, as shown in FIG. 6B, control is performed so that power is supplied to the LED 27 group arranged in a rectangular shape outside the two central LEDs 27 to emit light. Further, as shown in FIGS. 6C and 6D, the inner LED 27 is lit first, and the LED 27 is lit gradually toward the outer side. Thus, the arrangement of the LEDs 27 is not limited to a concentric circle with a different diameter, and may be a quadrilateral or other polygonal shape. In addition, the array of LEDs can be configured in various designs, such as a similar star shape or heart shape.

　また、別の実施例として、図７に示すように、橙色に着色された正方形の内側透明板２８と、この内側透明板２８の周りに配列される複数の内側ＬＥＤ群２９と、中心部に内側透明板２８及び内側ＬＥＤ群２９を配置する正方形の穴が設けられ、外周も正方形に形成された中間部透明板３０と、この中間部透明板３０の外周に配列される中間ＬＥＤ群３２と、これら中間部透明板３０及び中間ＬＥＤ群３２を配置する正方形の穴が設けられた外側透明板３１と、この外側透明板３１の外側に設けられる外側ＬＥＤ群３３とを備えた表示器１であってもよい。なお、図７は、説明を判り易くするために、図面上の発光する部分に斜線のハッチングを施している。 As another embodiment, as shown in FIG. 7, a square inner transparent plate 28 colored in orange, a plurality of inner LED groups 29 arranged around the inner transparent plate 28, and a central portion. An intermediate transparent plate 30 provided with a square hole in which the inner transparent plate 28 and the inner LED group 29 are arranged and the outer periphery is also formed in a square shape, and an intermediate LED group 32 arranged on the outer periphery of the intermediate transparent plate 30 The display 1 includes an outer transparent plate 31 provided with a square hole in which the intermediate transparent plate 30 and the intermediate LED group 32 are disposed, and an outer LED group 33 provided outside the outer transparent plate 31. There may be. In FIG. 7, in order to make the explanation easy to understand, hatched portions are given to light emitting portions on the drawing.

　図８に示すように、内側透明板２８、中間部透明板３０、及び外側透明板３１の裏面には光を乱反射させる乱反射層３４が設けられている。内側ＬＥＤ群２９の各ＬＥＤ２９ａは隣接する内側透明板２８の端面方向を指向しており、中間ＬＥＤ群３２の各ＬＥＤ３２ａは隣接する中間部透明板３０の端面方向を指向しており、外側ＬＥＤ群３３の各ＬＥＤ３３ａは隣接する外側透明板３１の端面方向を指向している。そして、各ＬＥＤからの光はそれぞれ内側透明板２８、中間部透明板３０、及び外側透明板３１の端面からこれら透明板の内部に入射し、裏面に設けられた乱反射層３４によって入射した光を乱反射させ、各透明板の前面を出光面として外部へ出光させることで、面光源とすることができ、より一層グレアを軽減することができる。 As shown in FIG. 8, an irregular reflection layer 34 for irregularly reflecting light is provided on the back surface of the inner transparent plate 28, the intermediate transparent plate 30, and the outer transparent plate 31. Each LED 29a of the inner LED group 29 is directed toward the end surface direction of the adjacent inner transparent plate 28, and each LED 32a of the intermediate LED group 32 is directed to the end surface direction of the adjacent intermediate transparent plate 30, and the outer LED group Each of the 33 LEDs 33 a is oriented in the direction of the end face of the adjacent outer transparent plate 31. The light from each LED enters the inside of these transparent plates from the end surfaces of the inner transparent plate 28, the intermediate transparent plate 30, and the outer transparent plate 31, respectively, and the light incident by the irregular reflection layer 34 provided on the back surface. By irregularly reflecting and emitting light to the outside using the front surface of each transparent plate as a light exit surface, a surface light source can be obtained, and glare can be further reduced.

　そして、このような表示器１であっても、点滅操作は、まず内側ＬＥＤ群２９を発光させ、その１０ミリ秒後に中間ＬＥＤ群３２を発光させ、さらにその１０ミリ秒後に外側ＬＥＤ群３３を発光させて、その後、内側ＬＥＤ群２９、中間ＬＥＤ群３２及び外側ＬＥＤ群３３が全て点灯した状態で１０ミリ秒が経過してから全消灯する操作を繰り返して点滅させる。 Even in such a display device 1, the blinking operation first causes the inner LED group 29 to emit light, causes the intermediate LED group 32 to emit light 10 milliseconds later, and further causes the outer LED group 33 to activate 10 milliseconds later. Then, the operation of turning off all the lights after 10 milliseconds has elapsed with all of the inner LED group 29, the intermediate LED group 32, and the outer LED group 33 turned on is repeatedly blinked.
