本考案は、鉄道用等の電球を光源とした既設の発光信号装置に互換使用される 発光素子を光源とした発光ユニット及びこの発光ユニットを備える発光信号装置 に関する。 The present invention relates to a light emitting unit using a light emitting element as a light source and a light emitting signal device including the light emitting unit, which is used interchangeably with an existing light emitting signal device using a light bulb for a railway or the like as a light source.
【０００２】[0002]
鉄道には、車両の安全運行を確保するためにね種々の保安用信号機や表示灯、 警報灯等の信号装置が線路に沿って設置されている。信号装置には、電車等の運 転手や自動車の運転手或いは歩行者等が夜間時等においても表示が確認可能なよ うに、内部に光源を備えた発光型信号装置が数多く設置されている。従来の発光 型信号装置は、一般に白熱電球、ナトリウム球管或いはその他の種々の電球が光 源として用いられている。 In railways, various security traffic lights and signaling devices such as indicator lights and warning lights are installed along the tracks to ensure the safe operation of vehicles. Many signaling devices are equipped with light-emitting signaling devices equipped with light sources so that drivers such as trains, drivers of automobiles, and pedestrians can check the display even at night. . Conventional light-emitting signal devices generally use an incandescent light bulb, a sodium bulb, or other various light bulbs as a light source.
【０００３】 例えば踏切に設置された従来の警報灯（閃光灯）５０は、図７及び図８に示す ように、背面部が裏蓋５２によって開閉される略筒状の筐体５１に、その前面開 口部を覆ってシールドビーム部材５３と拡散レンズ部材５４とが組み付けられる とともにシールドビーム部材５３の中心部に電球５５を取り付けてなる。シール ドビーム部材５３は、断面が略放物線形状を呈する略椀形に形成され、その中心 部に電球５５を内部空間５３ａに差し込む電球取付筒部５６が一体に形成されて いる。警報灯５０は、シールドビーム部材５３の内面に例えば赤色塗装を施すと ともに、赤色に着色した拡散レンズ部材５４が備えられる。For example, a conventional warning light (flash light) 50 installed at a railroad crossing has, as shown in FIGS. 7 and 8, a substantially cylindrical housing 51 whose back portion is opened and closed by a back cover 52, and a front surface thereof. The shield beam member 53 and the diffusion lens member 54 are assembled so as to cover the opening, and a bulb 55 is attached to the center of the shield beam member 53. The shield beam member 53 is formed in a substantially bowl shape having a substantially parabolic cross section, and is integrally formed with a bulb mounting tube portion 56 for inserting the bulb 55 into the internal space 53a at the center thereof. The warning light 50 is provided with, for example, a red coating on the inner surface of the shield beam member 53 and a diffusion lens member 54 colored red.
【０００４】 電球５５には、シングルフィラメント５５ａが採用され、ガラス球５５ｂを保 持する絶縁部材５５ｃから３本の端子片５５ｄ〜５５ｆが突設されてなるＦ型電 球が用いられている。電球５５は、発光部が電球取付筒部５６を介してシールド ビーム部材５３の内部空間５３ａに差し込まれるとともに、絶縁部材５５ｃの端 部が電球取付筒部５６の開口縁に係止される。電球５５は、この状態で電球取付 筒部５６の外周にねじ込まれる保持部材５７によって保持される。電球５５は、 各端子片５５ｄ〜５５ｆが裏蓋５２に取り付けた電源端子部５９に接続されたソ ケット部材５８に結合されて外部から電源が供給されるようにする。[0004] The bulb 55 employs a single filament 55a, and uses an F-type bulb having three terminal pieces 55d to 55f protruding from an insulating member 55c holding a glass bulb 55b. The light emitting portion of the light bulb 55 is inserted into the internal space 53a of the shield beam member 53 via the light bulb mounting tube portion 56, and the end of the insulating member 55c is locked to the opening edge of the light bulb mounting tube portion 56. In this state, the bulb 55 is held by a holding member 57 that is screwed to the outer periphery of the bulb mounting tube portion 56. The light bulb 55 is connected to a socket member 58 connected to a power terminal 59 attached to the back cover 52 so that power is supplied from the outside.
【０００５】 警報灯５０は、ソケット部材５８を介して外部から電源が投入されることによ って電球５５が点灯し、この電球５５から出射される出射光が拡散レンズ部材５ ４を介して外部に散光される。警報灯５０は、電球５５から出射される出射光の 一部がシールドビーム部材５３の放物内面５３ｂで反射されて拡散レンズ部材５ ４へと導かれ、この拡散レンズ部材５４を介して外部に散光される。警報灯５０ は、電球５５から出射される出射光が拡散レンズ部材５４に効率的に導かれて、 赤色の発光表示を行う。The warning light 50 turns on the electric bulb 55 when power is supplied from the outside via the socket member 58, and the emitted light from the electric bulb 55 is transmitted through the diffusion lens member 54. Light is scattered outside. The warning light 50 is configured such that a part of the light emitted from the light bulb 55 is reflected by the parabolic inner surface 53 b of the shield beam member 53 and guided to the diffusion lens member 54, and is externally transmitted through the diffusion lens member 54. It is scattered. In the warning light 50, the light emitted from the light bulb 55 is efficiently guided to the diffusion lens member 54, and a red light is displayed.
【０００６】[0006]
既設の警報灯５０は、光源として用いる電球５５の寿命が比較的短く、発熱量 も多く、消費電力も大きいといった問題がある。既設の警報灯５０は、上述した ように光源として１個のシングルフィラメントのＦ型電球５５を用いていること から、フィラメント５５ａの断芯、すなわち球切れが生じた場合に発光表示が行 われなくなって重大事故を引き起こす虞れや電車の運行に支障を来すといった問 題を生じさせる。 The existing warning light 50 has the problems that the life of the bulb 55 used as a light source is relatively short, the amount of heat generation is large, and the power consumption is large. As described above, the existing warning light 50 uses one single filament F-type bulb 55 as a light source, so that when the filament 55a is disconnected, that is, when the bulb is cut out, the light emission display is not performed. This can cause serious accidents and hinder train operation.
【０００７】 鉄道会社等においては、一般に所定の期間を定めて電球５５を光源とした発光 信号装置の電球を定期的に交換する対応を図っているが、電球５５の球切れの頻 度が多く緊急の保守対応を頻繁に余儀なくされ大きな負担となっている。発光信 号装置においては、上述した問題を解決するために、光源としてＦ型電球と比較 して寿命が長く、発熱量や消費電力も小さいといった特性を有する多数個の発光 素子（ＬＥＤ：ｌｉｇｈｔ−ｅｍｉｔｔｉｎｇ ｄｉｏｄｅ、発光ダイオード） を用いたものが提案されている。かかる発光信号装置は、表示特性の向上や省電 力化が図られるとともに、発光素子の一部に球切れを生じても直ちに表示作用が 損なわれることが無いので保守性にも優れるといった種々の利点がある。[0007] Railway companies and the like generally take measures to periodically replace the light bulb of the light emitting signal device using the light bulb 55 as a light source for a predetermined period of time. Emergency maintenance is frequently required, which is a heavy burden. In order to solve the above-mentioned problems, the light emitting signal device has a large number of light emitting elements (LED: light- Emitting diode (light emitting diode) has been proposed. Such a light-emitting signal device is not only capable of improving display characteristics and reducing power consumption, but also has excellent maintainability since the display operation is not immediately impaired even if a part of the light-emitting element is broken. There are advantages.
【０００８】 しかしながら、かかる新型の発光信号装置は、いずれも光源に発光素子を用い た独自の装置として開発されたものであり、既設の発光信号装置との互換性が図 られておらず全体交換が必要となる。新型の発光信号装置は、電球を用いた既設 の発光信号装置の変換のために、鉄道会社等に対して、装置費用、交換費用或い はケーブル交換等の莫大な設備投資を強いるでその対応がなかなか促進されてい ない状況にある。However, these new light emitting signal devices have been developed as original devices each using a light emitting element as a light source, and are not compatible with existing light emitting signal devices. Is required. In order to convert existing light-emitting signal devices using light bulbs, the new type of light-emitting signal devices will require a huge investment in equipment such as equipment costs, replacement costs, or cable replacement for railway companies, etc. Has not been promoted.
【０００９】 したがって、本考案は、既設の発光信号装置に対して互換使用を可能とする発 光信号装置用発光ユニット及びこの発光ユニットを備えることにより全体交換を 要せずに表示特性の向上や省電力化或いは保守性の向上が図られる発光信号装置 を提供することを目的に提案されたものである。Therefore, the present invention provides a light-emitting unit for a light-emitting signal device that can be used interchangeably with an existing light-emitting signal device, and by providing this light-emitting unit, it is possible to improve display characteristics without requiring replacement as a whole. It has been proposed for the purpose of providing a light emitting signal device capable of saving power or improving maintainability.

【００４６】 なお、第１の発光部３５乃至第４の発光部３８は、各プリントシートが配線基 板によって構成されてもよいことは勿論である。また、第１の発光部３５乃至第 ４の発光部３８は、各発光素子群を拡散レンズ部材６側に向けて各プリントシー トを連結部材３４に支持したが、上述した第１の実施の形態の発光ユニット２の ように、例えば第１の発光部３５と第２の発光部３６と及び第３の発光部３７と 第４の発光部３８とで対をなすようにし、それぞれの組の発光素子群が互いに対 向するようにして連結部材３４に支持するようにしてもよい。In the first to fourth light emitting units 35 to 38, each printed sheet may of course be constituted by a wiring board. In the first to fourth light emitting units 35 to 38, each print sheet is supported by the connecting member 34 with each light emitting element group facing the diffusion lens member 6 side. Like the light-emitting unit 2 of the embodiment, for example, the first light-emitting unit 35, the second light-emitting unit 36, and the third light-emitting unit 37 and the fourth light-emitting unit 38 form a pair. The light emitting element groups may be supported by the connecting member 34 so as to face each other.
【００４７】 以上のように構成された発光ユニット３１は、図５矢印で示すように、第４の 発光部３８側から発光ユニット取付筒部１２の発光ユニット取付孔１３内に差し 込まれる。発光ユニット３１は、発光素子駆動配線基板３３が発光ユニット取付 筒部１２の開口縁に突き当たって係止される。発光ユニット３１は、この状態で 発光ユニット取付筒部１２の外周ネジ１４にねじ込まれる保持部材８によって保 持される。保持部材８は、発光ユニット取付筒部１２の開口縁に突き当てられた 発光素子駆動配線基板３３を、この開口縁と底部８ｂとによって挟持することで 発光ユニット３１を保持する。The light emitting unit 31 configured as described above is inserted into the light emitting unit mounting hole 13 of the light emitting unit mounting cylinder 12 from the fourth light emitting unit 38 side, as shown by the arrow in FIG. In the light emitting unit 31, the light emitting element driving wiring board 33 abuts on the opening edge of the light emitting unit mounting tube portion 12 and is locked. In this state, the light emitting unit 31 is held by the holding member 8 that is screwed into the outer peripheral screw 14 of the light emitting unit mounting cylinder 12. The holding member 8 holds the light emitting unit 31 by sandwiching the light emitting element driving wiring board 33 abutting against the opening edge of the light emitting unit mounting tubular portion 12 between the opening edge and the bottom 8b.
【００４８】 発光ユニット３１は、上述したように第１の発光部３５乃至第４の発光部３８ がシールドビーム部材５の内部空間５ａに臨ませられるとともに、発光素子駆動 配線基板３３がソケット部材３２に結合されることによって外部電源が供給され る。ソケット部材３２は、図７によって説明したように、電球５５に設けられた 端子片５５ｄ〜５５ｆが直接嵌合されるソケット部材３２が共用される。ソケッ ト部材３２には、発光素子駆動配線基板３３に設けたプラグ片３９が嵌合される 所定個のプラグ孔４９が形成されるとともに、詳細を省略するが各プラグ孔４９ 内に設けた電極と接続されたリード線３２ａが引き出されている。各リード線３ ２ａには、それぞれ端子片３２ｂが接続されており、これら端子片３２ｂが図示 しない外部電源と接続されることによって発光ユニット３１に電源を供給する。As described above, the light-emitting unit 31 has the first light-emitting portion 35 to the fourth light-emitting portion 38 facing the internal space 5 a of the shield beam member 5, and the light-emitting element driving wiring board 33 is connected to the socket member 32. External power is supplied by being coupled to the power supply. As described with reference to FIG. 7, the socket member 32 in which the terminal pieces 55 d to 55 f provided on the light bulb 55 are directly fitted is used as the socket member 32. The socket member 32 is formed with a predetermined number of plug holes 49 into which plug pieces 39 provided on the light emitting element drive wiring board 33 are fitted, and an electrode provided in each plug hole 49 is omitted in detail. The lead wire 32a connected to is drawn out. Terminal strips 32b are connected to the respective lead wires 32a, and power is supplied to the light emitting unit 31 by connecting these terminal strips 32b to an external power supply (not shown).
【００４９】 発光信号装置３０においては、ソケット部材３２を介して発光ユニット３１に 電源が供給され、この発光ユニット３１の発光素子駆動配線基板３３の発光素子 駆動回路を介して第１の発光部３５乃至第４の発光部３８の各発光素子群が駆動 されて点灯する。発光信号装置３０においては、第１の発光部３５乃至第４の発 光部３８の各発光素子群から出射された出射光がシールドビーム部材５の放物内 面５ｂによって前面開口側へと効率的に導かれ、部拡散レンズ部材６から外部へ と散光される。In the light-emitting signal device 30, power is supplied to the light-emitting unit 31 through the socket member 32, and the first light-emitting unit 35 is driven through the light-emitting element drive circuit of the light-emitting element drive wiring board 33 of the light-emitting unit 31. The respective light emitting element groups of the fourth to fourth light emitting units 38 are driven and turned on. In the light-emitting signal device 30, the light emitted from each light-emitting element group of the first light-emitting unit 35 to the fourth light-emitting unit 38 is efficiently directed toward the front opening by the paraboloid inner surface 5 b of the shield beam member 5. And is scattered from the partial diffusion lens member 6 to the outside.
【００５０】 発光信号装置３０においては、上述したように第１の発光部３５乃至第４の発 光部３８が連結部材３４を介して同軸上に重なり合うようにして組み合わされて 構成されている。発光信号装置３０においては、第１の発光部３５乃至第４の発 光部３８の各発光素子群が各プリントシートに対してその外周部から放射状に突 出するように実装されてなる。したがって、発光信号装置３０においては、基端 側の発光部の発光素子群から出射される出射光が先端側の発光部に遮られること 無くシールドビーム部材５の内部空間に放射される。As described above, the light emitting signal device 30 is configured such that the first light emitting unit 35 to the fourth light emitting unit 38 are coaxially overlapped with each other via the connecting member 34. In the light-emitting signal device 30, each light-emitting element group of the first light-emitting portion 35 to the fourth light-emitting portion 38 is mounted on each print sheet so as to radially protrude from the outer peripheral portion thereof. Therefore, in the light emitting signal device 30, the emitted light emitted from the light emitting element group of the light emitting section on the base end side is radiated into the internal space of the shield beam member 5 without being blocked by the light emitting section on the front end side.
【００５１】 発光信号装置３０においても、それぞれ複数個の発光素子群を有する第１の発 光部３５乃至第４の発光部３８が、既設の電球５５に代えて光源として互換使用 される。発光信号装置３０は、発光素子群を光源として用いることで上述した発 光信号装置１と同様に、表示特性の向上や省電力化が図られるとともに、発光素 子の一部に球切れを生じても直ちに表示作用が損なわれることが無く保守性にも 優れるといった特性を有する。In the light emitting signal device 30 as well, the first to fourth light emitting units 35 to 38 each having a plurality of light emitting element groups are used interchangeably as light sources instead of the existing light bulb 55. By using the light emitting element group as a light source, the light emitting signal device 30 can improve display characteristics and save power similarly to the light emitting signal device 1 described above, and can cause a part of the light emitting element to be broken. However, it has the characteristics that the display function is not immediately impaired and the maintainability is excellent.
【００５２】 発光信号装置３０は、第１の発光部３５乃至第４の発光部３８を備えることか ら、発光信号装置１と比較してもさらに明るい警報表示が可能となる。発光信号 装置３０は、発光素子駆動配線基板３３のプラグ片３９をソケット部材３２のプ ラグ孔４９に対して直接嵌合するようにしたことにより、構造の簡易化が図られ るようになる。Since the light emitting signal device 30 includes the first light emitting unit 35 to the fourth light emitting unit 38, a brighter alarm display can be performed as compared with the light emitting signal device 1. The structure of the light emitting signal device 30 can be simplified by directly fitting the plug pieces 39 of the light emitting element drive wiring board 33 into the plug holes 49 of the socket member 32.
【００５３】 なお、本考案は、上述した各実施の形態に限定されるものではなく、電球５５ を光源とした種々の発光信号装置に互換適用されることは勿論である。発光ユニ ット２は、シールドビーム部材５や拡散レンズ部材６の着色に合わせて適宜の発 光色を有する発光素子を用いるようにしてもよいことは勿論である。The present invention is not limited to the above-described embodiments, but is of course applicable to various light emitting signal devices using the light bulb 55 as a light source. As a matter of course, the light-emitting unit 2 may use a light-emitting element having an appropriate emission color in accordance with the coloring of the shield beam member 5 and the diffusion lens member 6.
【００５４】[0054]
以上詳細に説明したように、本考案によれば、既設の発光信号装置に対して電 球との交換操作により、表示特性の向上や省電力化を図り、発光素子の一部に球 切れを生じても直ちに表示作用が損なわれることが無く保守性にも優れた発光信 号装置を得ることができる。発光信号装置は、既設の装置において、光源として 電球に代えて発光ユニットを用いることで、膨大な設備投資を不要とさせる。 As described above in detail, according to the present invention, by replacing the existing light emitting signal device with a light bulb, display characteristics are improved and power consumption is reduced, and a part of the light emitting element is cut off. Even if it occurs, it is possible to obtain a light emitting signal device which does not impair the display function and has excellent maintainability. The light-emitting signal device eliminates huge capital investment by using a light-emitting unit instead of a light bulb as a light source in the existing device.
