Description
【0001】[0001]
本考案は音響再生装置等の電子機器操作押し釦装置にかかわり、特に押し釦を 後方から照明する押し釦照明装置に好適な光源取付装置に関する。 The present invention relates to a push button device for operating an electronic device such as a sound reproducing device, and more particularly to a light source mounting device suitable for a push button lighting device that illuminates a push button from the rear.
【0002】[0002]
電子機器を操作する押し釦は通常、操作面に押し釦の操作機能を表わす文字や 図形等が表示され、これら文字や図形等の表示部は押し釦の後方に配設されたラ ンプ光源やLED素子によって照明されるようになっている。 A push button for operating an electronic device usually has characters or figures indicating the operation function of the push button displayed on the operation surface, and the display part of these characters or figures is a lamp light source arranged behind the push button. It is designed to be illuminated by LED elements.
【0003】 図3は従来の押し釦照明用光源の取付状態を説明する斜視図であり、互いに色 彩の異なる複数の光源を用いて単一押し釦の複数表示部を照明する例を示してい る。図において、1は押し釦、2はプリント基板、3は照明用の導光体、4と5 は光源としてのLEDで、互いに異なる発光色の素子である。FIG. 3 is a perspective view for explaining a mounting state of a conventional push button illumination light source, and shows an example of illuminating a plurality of display portions of a single push button by using a plurality of light sources having different colors. It In the figure, 1 is a push button, 2 is a printed circuit board, 3 is a light guide for illumination, and 4 and 5 are LEDs as a light source, which are elements of different emission colors.
【0004】 押し釦1は通常アクリル等の光透過性樹脂により成形され、表面処理が施され た操作面1cには、剥離加工などにより文字表示部1aが形成され、その上方に は導光体3が嵌合するインジケータ窓1bが穿設されている。文字表示部1aは 円筒形のLED4により照明され、他方のインジケータ窓1bに嵌合された導光 体には、直方形のLED5の照明光が当てられる。また、押し釦1の背面側の中 央部には押圧棒(図示されない)が一体成形され、この押圧棒によって機器内部 のスイッチが押圧操作されるようになっている。この押し釦1は機器前面パネル の押し釦開口部に臨ませ取り付けられる。The push button 1 is usually formed of a light-transmissive resin such as acrylic resin, and the surface-treated operation surface 1c is provided with a character display portion 1a by a peeling process or the like. An indicator window 1b into which 3 is fitted is provided. The character display portion 1a is illuminated by the cylindrical LED 4, and the illumination light of the rectangular LED 5 is applied to the light guide body fitted in the other indicator window 1b. In addition, a push rod (not shown) is integrally formed in the center of the back side of the push button 1, and a switch inside the device is pushed by the push rod. The push button 1 is attached so as to face the push button opening on the front panel of the device.

図3の従来例は押し釦の文字表示部とインジケータ部の複数表示部を互いに異 なる色彩の2つのLED素子を応用して低電力で効率的に照明できるなど、多く りの利点が認められるが、他方では次のような問題点が指摘されていることも事 実であり、その改善が望まれていた。 The conventional example shown in FIG. 3 has many advantages such as efficient lighting with low power by applying two LED elements of different colors to the character display part of the push button and the plurality of display parts of the indicator part. On the other hand, however, the following problems were pointed out, and improvements were desired.
【0006】 第1に、LEDの光を効率よく押し釦に照射するためには、押し釦の押圧スト ロークを考慮した上でLEDをできるだけ押し釦に近付けることが望ましい。し かし、上記従来例はLEDを直接プリント基板に半田付けする構成であるため、 LEDを押し釦に近付けるための高さ調整が殆ど不可能である。第2に、互いに 発光色の異なるLED素子を相互に近接させると、光の干渉による混色が生じて 意匠効果を損なうおそれがある。第3に、LED素子は発光色が限定されており 、かつ、光量がタングステンランプより少ないという欠点がある。そして、従来 例の場合はインジケータ窓1bや導光体3などを成形するために成形金型が複雑 になり、コストアップの要因になっていた。First, in order to efficiently radiate the light of the LED to the push button, it is desirable to place the LED as close to the push button as possible in consideration of the press stroke of the push button. However, in the above-mentioned conventional example, since the LED is directly soldered to the printed circuit board, it is almost impossible to adjust the height for bringing the LED close to the push button. Secondly, when LED elements having different emission colors are brought close to each other, color mixing due to light interference may occur and the design effect may be impaired. Thirdly, the LED element has a drawback that the emission color is limited and the light quantity is smaller than that of the tungsten lamp. In the case of the conventional example, since the indicator window 1b, the light guide 3 and the like are molded, the molding die becomes complicated, which causes a cost increase.
【0007】 本考案は上記事情に鑑みなされたもので、光源の高さ調整が可能であるととも に、光漏れ防止可能の取付部材を介添して光源を取付け、押し釦を効率的に照明 することにより、優れた意匠効果が得られる光源取付装置を具備する押し釦照明 装置を提供することを目的としている。The present invention has been made in view of the above circumstances, and the height of the light source can be adjusted, and the light source is attached through an attachment member capable of preventing light leakage to efficiently illuminate the push button. By doing so, it is an object of the present invention to provide a push-button lighting device including a light source mounting device that achieves an excellent design effect.
【0008】[0008]
上記目的を達成するために本考案の光源取付装置では、単一押し釦の後方に複 数の光源を配設し、該押し釦の操作面に形成された複数の表示部を該光源により 個別に照明する押し釦照明装置の光源取付装置において、第1の光源を配設する 載置部と、該載置部と第1の光源に隣接して配置された第2の光源との間に立設 され光を遮断する遮光壁とを具備している。 In order to achieve the above object, in the light source mounting device of the present invention, a plurality of light sources are arranged behind a single push button, and a plurality of display portions formed on the operation surface of the push button are individually separated by the light sources. In a light source mounting device for a push-button lighting device that illuminates in a vertical direction, between a mounting portion on which a first light source is disposed and a second light source disposed adjacent to the mounting portion and the first light source. It has a light-shielding wall that stands upright and blocks light.
【0009】[0009]
載置部には第1の光源であるLEDが載置される。LEDは段差のある載置部 に押し釦に近接して配設され、押し釦のインジケータ部を効率的に照明する。第 2光源によるランプ光は文字表示部を直接照明するが、その側方への照射光は遮 光壁により完全に遮断され、2つの表示部と光源が互いに近接位置に設けられる 構成であっても光の干渉がなく、複数表示部は互いに異なる色彩で照明される。 The LED, which is the first light source, is mounted on the mounting portion. The LED is disposed in the stepped mounting portion in the vicinity of the push button, and efficiently illuminates the indicator portion of the push button. The lamp light from the second light source directly illuminates the character display portion, but the light irradiating to the side of the character display portion is completely blocked by the light blocking wall, and the two display portions and the light source are provided in close proximity to each other. However, there is no light interference, and the plurality of display parts are illuminated in different colors.
【0010】[0010]
以下、本考案を図面を参照して説明する。なお、図1は本考案の実施例を示す 組立斜視図、図2は図1の矢印A側から押し釦を見た断面図である。図中、10 は押し釦、20はプリント基板、30は光源をプリント基板20に取り付ける際 に介添して、補助アダプタとして機能する光源取付装置であり、以下光源取付部 材という。 Hereinafter, the present invention will be described with reference to the drawings. 1 is an assembled perspective view showing an embodiment of the present invention, and FIG. 2 is a sectional view of the push button viewed from the arrow A side in FIG. In the figure, 10 is a push button, 20 is a printed circuit board, 30 is a light source mounting device that functions as an auxiliary adapter when the light source is mounted on the printed circuit board 20, and is hereinafter referred to as a light source mounting member.
【0011】 押し釦10は光透過性樹脂を成形したもので、その操作面11に表面処理を施 し、レーザ加工又は剥離処理により文字表示部12とインジケータ部13が形成 される。文字表示部12は必要に応じて光透過性の色彩が付加される。また、押 し釦10の背面側中央部にはスイッチ23を押圧する押圧棒15が一体成形され 、更に文字表示部12とインジケータ部13を互いに光学的に遮断するための隔 壁16が形成されている。押し釦10は機器の前面パネルであるエスカッション 25に開設された押し釦開口部26に操作面11を臨ませるとともに、押圧棒1 5の先端がスイッチ23の頭部に当接するように取り付けられる。The push button 10 is made of a light-transmissive resin, and its operation surface 11 is subjected to surface treatment, and a character display portion 12 and an indicator portion 13 are formed by laser processing or peeling treatment. The character display portion 12 is provided with a light-transmitting color as necessary. In addition, a push rod 15 for pushing the switch 23 is integrally formed in the central portion on the back side of the push button 10, and a partition wall 16 for optically blocking the character display portion 12 and the indicator portion 13 from each other is formed. ing. The push button 10 is mounted so that the operation surface 11 is exposed to the push button opening 26 formed in the escutcheon 25, which is the front panel of the device, and the tip of the push rod 15 contacts the head of the switch 23.
【0012】 光源取付部材30は第1の光源であるLED素子22を定位置に保持するLE D載置部31と、プリント基板20に直接取り付けられた第2の光源としてのタ ングステン型照明ランプ21の周囲をカバーするランプ保持部32が形成され、 その下方両端部には係合爪34を有す一対の支持脚33,33が一体形成されて いる。この取付部材30をプリント基板20に取り付ける際は両支持脚33,3 3を狭めながらプリント基板20の穴に挿入することにより係合爪34,34が 穴に係合し、取付部材30はプリント基板20上に固定される。The light source mounting member 30 is an LED mounting portion 31 which holds the LED element 22 which is the first light source in a fixed position, and a tungsten type illumination lamp which is directly mounted on the printed circuit board 20 and serves as a second light source. A lamp holding portion 32 is formed to cover the periphery of 21, and a pair of support legs 33, 33 having engaging claws 34 are integrally formed at both lower ends thereof. When the mounting member 30 is mounted on the printed circuit board 20, the supporting claws 33, 33 are narrowed and inserted into the holes of the printed circuit board 20 so that the engaging claws 34, 34 engage with the holes and the mounting member 30 is printed. It is fixed on the substrate 20.
【0013】 図2の断面図から理解されるように、LED載置部31は台座機能のある段差 が設けられ、LED素子22が押し釦10に近接する位置に1段高く、台座に位 置決めされるように取り付けられる。LED22の取付時にリード線22aは載 置部31の貫通穴を通してプリント基板20に半田付けし固定される。また、ラ ンプ保持部32とLED載置部31との間にはランプ光を遮断する遮光壁35が 立設されており、LED側への光漏れが防止される。As can be seen from the cross-sectional view of FIG. 2, the LED mounting portion 31 is provided with a step having a pedestal function, and the LED element 22 is raised by one step at a position close to the push button 10 and positioned on the pedestal. It is installed as decided. At the time of mounting the LED 22, the lead wire 22 a is soldered and fixed to the printed circuit board 20 through the through hole of the mounting portion 31. Further, a light blocking wall 35 that blocks the lamp light is erected between the lamp holding portion 32 and the LED mounting portion 31, so that light leakage to the LED side is prevented.
【0014】 押し釦装置の組立てに際して、スイッチ23、照明ランプ21、及び光源取付 部材30等の各部品はあらかじめプリン基板20に取り付けておくが、LED2 2は取付部材30の取付後LED載置部31に取り付けられる。そして、押し釦 操作面11をエスカッション25の内側から開口部26に挿通し、次にプリント 基板20をエスカッション25の後方に固定する。押し釦10の取付完了後は、 押し釦10を押圧操作すればスイッチ23が閉じられ、回路が動作する。ここで 、スイッチ23の回路がランプ21、またはLED22に接続されているならば 、押し釦10の操作とともにランプ21またはLED22が点灯し、押し釦10 の後方に照明光が照射される。LED22とランプ21が同時に点灯している場 合、ランプ光は遮光壁35に遮断され、側方すなわちLED22側へは照射され ない。そして、このランプ光は押し釦10の中央部隔壁16によっても遮光され 、文字表示部12のみを照明するが、インジケータ部13には届かない。したが って、ランプ光に照射された文字表示部12の色彩とLED22の光が互いに干 渉することはなく、混色が発生しない。At the time of assembling the push button device, the switch 23, the illumination lamp 21, the light source mounting member 30 and other components are mounted on the pudding board 20 in advance. It is attached to 31. Then, the push button operation surface 11 is inserted into the opening 26 from the inside of the escutcheon 25, and then the printed circuit board 20 is fixed to the rear of the escutcheon 25. After the push button 10 is attached, when the push button 10 is pressed, the switch 23 is closed and the circuit operates. Here, if the circuit of the switch 23 is connected to the lamp 21 or the LED 22, the lamp 21 or the LED 22 is turned on when the push button 10 is operated, and the illumination light is emitted to the rear of the push button 10. When the LED 22 and the lamp 21 are turned on at the same time, the lamp light is blocked by the light shielding wall 35 and is not emitted to the side, that is, the LED 22 side. The lamp light is also blocked by the central partition wall 16 of the push button 10 to illuminate only the character display portion 12, but does not reach the indicator portion 13. Therefore, the color of the character display portion 12 and the light of the LED 22 which are irradiated with the lamp light do not interfere with each other, and the color mixing does not occur.
【0015】 また、LED22は光源として長寿命である反面、ランプ21に比較して光量 が少ないが、LED22は段差があるLED載置部31に配設されているため、 近接位置からインジケータ部13をLED素子22の発光色で明るく効率的に照 明することができる。そして、第2の光源にはタングステン系ランプを用いたの で、文字表示部12の色彩を自由に変更することが可能である。Further, although the LED 22 has a long life as a light source, the LED 22 has a smaller amount of light than the lamp 21, but since the LED 22 is arranged in the LED mounting portion 31 having a step, the indicator portion 13 is located from the close position. Can be illuminated brightly and efficiently with the emission color of the LED element 22. Since the tungsten-based lamp is used as the second light source, the color of the character display portion 12 can be freely changed.
【0016】 なお、取付部材30は素材の色、または塗装の色を考慮することにより、ラン プ光を素材のもつ色彩で文字表示部12に反映させることができる。例えば、素 材が白色系であれば明るい色彩を選ぶこともできるし、逆に素材が黒色系であれ ば暗色系の色彩にすることも可能である。The mounting member 30 can reflect the lamp light on the character display portion 12 in the color of the material by considering the color of the material or the color of the coating. For example, if the material is white, a bright color can be selected, and conversely, if the material is black, a dark color can be selected.
【0017】[0017]
以上、説明したように本考案の光源取付装置は、第1光源を配設する載置部と 、遮光壁とを具備したので、第1の光源は押し釦のインジケータ部を近接位置か ら効率よく照明し、第2の光源は押し釦の文字表示部を直接照明し、その側方へ の照射光は遮光壁によって遮断され、第1の光源に影響を与えない。したがって 、複数表示部及び第1の光源と第2の光源を相互に近接位置に設ける構成であっ ても、互いに異なる色彩で照明される複数表示部は光の干渉がなく、意匠的に優 れた照明装置を提供することができる。 As described above, since the light source mounting device of the present invention includes the mounting portion for disposing the first light source and the light shielding wall, the first light source can efficiently move the indicator portion of the push button from the close position. Well illuminated, the second light source directly illuminates the character display portion of the push button, and the light emitted to the side thereof is blocked by the light shielding wall, and does not affect the first light source. Therefore, even if the plurality of display units and the first light source and the second light source are arranged in close proximity to each other, the plurality of display units illuminated with different colors do not cause light interference and are excellent in design. It is possible to provide a lighting device.
