信号光の報知を行う回転警告灯として、従来、透光性を有するグローブと、第１シャーシに装着され、該グローブ内に内蔵した回転灯ユニットから光機部分を構成する。後ケースと、スピーカを一体的に形成した前ケースのそれぞれ上縁に該第１シャーシを、下縁に第２シャーシを介して組み付けた本体部分を構成する。回転警告灯は、上記光機部分と、本体部分を一体に組み立てて構成し、該後ケース内に配線や回路基板などを収容しうる適宜空間を設けたものが開示される（特許文献１参照）。上記の構成によって、大型のスピーカを採用しつつ、複数の回路基板を効率よく収容して、スピーカ内蔵の回転警告灯をコンパクトに提供することができた、とされる。 Conventionally, as a rotating warning lamp for reporting signal light, a light-transmitting globe and a rotating lamp unit mounted in the first chassis and built in the globe constitute an optical unit. A main body is formed by assembling the first chassis on the upper edge of the rear case and the front case integrally formed with the speaker, and the lower chassis via the second chassis. A rotation warning lamp is disclosed in which the above-mentioned optical device part and main body part are integrally assembled, and an appropriate space is provided in the rear case for accommodating wiring, a circuit board, and the like (see Patent Document 1). ). According to the above configuration, a large-sized speaker can be adopted, and a plurality of circuit boards can be accommodated efficiently, and a rotation warning light with a built-in speaker can be provided in a compact manner.

また従来、パネル式警告灯として、一方の平面に表面処理を施した両翼若しくは片翼の透光性材料からなる薄型導光板パネルと、天井面及び壁面に設置可能な本体取付台と、本体取付台を覆う化粧カバーと、本体取付台に化粧カバーを固定する固着具と、本体取付台上部にて薄型導光板パネルの内側端面から外側に向くように配置された複数のカラーＬＥＤ素子列及び制御回路で構成される光源と、電力を供給する電源装置とを具備したものが開示される（特許文献２参照）。地震通報システムを通じて地震の主要動が到達する前に警告を視覚に伝えるうえで、遠方からの視認性を得るだけの十分な光量を有し、また、どの方角からも良好な視認性を継続して有するとともに、人に対する威圧感がない警告灯を提供する、とされる。 Conventionally, as a panel-type warning light, a thin light guide plate panel made of a light-transmitting material of both wings or one wing with surface treatment on one plane, a main body mounting base that can be installed on a ceiling surface and a wall surface, and a main body mounting A decorative cover for covering the base, a fixing member for fixing the decorative cover to the main body mounting base, and a plurality of color LED element arrays arranged at the upper portion of the main body mounting base so as to face outward from the inner end face of the thin light guide plate panel and control A device including a light source configured by a circuit and a power supply device that supplies electric power is disclosed (see Patent Document 2).

しかしながら、上記特許文献１に開示されている回転警告灯をはじめ、従来のスピーカ一体型の警告灯の多くは、スピーカが本体下部に設けられるものであった。このため、本体下部に備えるスピーカの発生方向が限定されてしまい、報知音を取り付け面の正面（法線）側へ効率的に拡声することができなかった。
一方、上記特許文献２に開示されている警告灯のように横長のグローブを使用している場合、その形状から、報知光をその周囲から効率的に拡光することができなかった。なお、意匠登録１３９０８６４号に示されるように、横長のグローブの上部にスピーカが取り付けられることはあっても、その形態の多くは、横長のグローブを左右に分離させるようにして組み込まれるものであった。このため、報知音を取り付け面の正面（法線）側ないしその周囲へ効率的に拡声すると共に、報知光をその周囲から効率的に拡光することは、スピーカ及び発光部の配置上、困難であった。 However, many of the conventional speaker-integrated warning lights including the rotating warning light disclosed in Patent Document 1 have a speaker provided at the lower part of the main body. For this reason, the direction of generation of the speaker provided at the lower part of the main body is limited, and the notification sound cannot be efficiently amplified to the front (normal) side of the mounting surface.
On the other hand, when a horizontally long glove is used as in the warning light disclosed in Patent Document 2, the notification light cannot be efficiently diffused from its surroundings due to its shape. As shown in Design Registration No. 1390864, even if a speaker is attached to the top of a horizontally long glove, many of the forms are incorporated so that the horizontally long glove is separated into left and right. It was. For this reason, it is difficult to efficiently spread the notification sound to the front (normal) side of the mounting surface or its surroundings and to efficiently spread the notification light from the surroundings because of the arrangement of the speaker and the light emitting unit. Met.

また、仮に、周囲へ回転警告を行う特許文献１の形状のグローブの報知光において、グローブ中央上部にスピーカを一体的に取り付けようとすると、報知音の拡声のため、スピーカ取付け部に拡声孔を設ける必要が生じる。このため、屋外へ設置する際にこの孔からグローブ内に浸水して発光部が故障してしまうという問題があった。 In addition, in the notification light of the glove in the shape of Patent Document 1 that warns the rotation to the surroundings, if the speaker is to be integrally attached to the upper center of the globe, a speaker hole is provided in the speaker attachment portion for the purpose of sounding the notification sound. It is necessary to provide it. For this reason, when installing outdoors, there was a problem that the light emitting part would break down due to water being immersed in the globe from this hole.

そこで本発明は、スピーカと報知灯とを上部に一体化させたコンパクトな構成とすることで、報知音を取り付け面の正面（法線）側ないしその周囲へ効率的に拡声すると共に、報知光をその周囲から効率的に拡光することができ、さらに止水性に優れた報知灯を提供することを課題とする。 Therefore, the present invention has a compact structure in which the speaker and the notification lamp are integrated at the upper portion, so that the notification sound can be efficiently amplified to the front (normal) side of the mounting surface or the periphery thereof, and the notification light can be obtained. It is an object of the present invention to provide a notification lamp that can efficiently spread light from the surroundings and that is excellent in water stoppage.

上記課題に鑑みて、本発明においては、以下の手段を講じるものとしている。但し以下において構成の名称に続けて記載する数字乃至アルファベットは、図面の理解のために便宜的に付した符号であり、これによって構成の概念ないし形状、構造を限定する趣旨ではない。 In view of the above problems, the following measures are taken in the present invention. However, numerals or alphabets that are described after the names of the components in the following are reference numerals given for the sake of understanding of the drawings, and are not intended to limit the concept, shape, or structure of the configurations.

（１）本発明に係る報知灯は、
下面を取り付け面とした短筒体からなると共に、その上部に、プリズム放光体１３及び発光素子を含む発光装置を備えた本体部１と、
本体部１の上部を覆って取り付けられるドーム状のグローブ２と、
グローブ２の頂部中央に形成された中央孔２０の上方を覆って取り付けられる蓋状の拡声プレート３と、
グローブ２の前記中央孔２０の下方を覆ってグローブ２の内側に取り付けられる防水スピーカ４と、を具備してなり、
前記防水スピーカ４は、上方へ解放した円柱状のフレームと、フレームの上部周囲から円柱内を覆って取り付けられた振動板とを、連続した防水構造で有すると共に、フレームの上部周囲に環状の止水材４Ｇが係止され、
前記フレームの上部周囲の環状の止水材４Ｇがグローブ２の中央孔２０の周囲に圧着することで、止水構造をなすことを特徴とする。 (1) The notification lamp according to the present invention is:
A main body 1 comprising a short cylindrical body having a lower surface as a mounting surface, and having a light emitting device including a prism light emitter 13 and a light emitting element on the upper surface,
A dome-shaped glove 2 attached to cover the upper part of the main body 1;
A lid-like loudspeaker plate 3 that is attached to cover the upper part of the central hole 20 formed in the center of the top of the globe 2;
A waterproof speaker 4 that covers the lower side of the central hole 20 of the globe 2 and is attached to the inside of the globe 2,
The waterproof speaker 4 has a cylindrical frame released upward and a diaphragm attached to cover the inside of the cylinder from the upper periphery of the frame in a continuous waterproof structure, and an annular stop around the upper portion of the frame. Water material 4G is locked,
An annular waterproofing material 4G around the upper part of the frame is pressed against the periphery of the central hole 20 of the globe 2 to form a waterproofing structure.

すなわち、拡声プレートと止水材たるパッキンと防水スピーカとをドーム状のグローブの中央頂部に密着して組み合わせることで、コンパクトな全体形状からなる、止水性に優れた報知灯をなすことができる。 That is, by combining the loudspeaker plate, the waterproofing material packing, and the waterproof speaker in close contact with the central top of the dome-shaped glove, an information lamp having a compact overall shape and excellent in water-stopping property can be formed.

（２）前記報知灯において、防水スピーカ４は、フレーム上部周囲に鍔状の張出部が一体的に形成されると共に、この張出部の下面の一部分にて結線部を有し、また、前記張出部と当接してグローブの頂部内面に圧着固定される短環状の固定具５をさらに具備してなることが好ましい。
上記構造によって、グローブの中央孔を塞いで防水スピーカがグローブ上部内面に圧着状態で吊持されると共に、張出部の上面とグローブの内面との間に止水材４Ｇが介設されることで確実な止水構造をなす。また、張出部の下面にてスピーカ結線され、結線部を固定具５で圧着することで結線部の防水を保ちながら断線を防止することができる。 (2) In the notification lamp, the waterproof speaker 4 is integrally formed with a hook-shaped protruding portion around the upper portion of the frame, and has a connection portion at a part of the lower surface of the protruding portion. It is preferable to further comprise a short annular fixture 5 that is in contact with the protruding portion and is pressure-bonded to the inner surface of the top of the globe.
With the above structure, the waterproof speaker is suspended from the upper surface of the globe in a crimped state by closing the central hole of the globe, and the water stop material 4G is interposed between the upper surface of the overhanging portion and the inner surface of the globe. With a reliable water stop structure. In addition, the speaker is connected to the lower surface of the overhang portion, and the connection portion is crimped with the fixture 5 to prevent disconnection while keeping the connection portion waterproof.

（３）前記報知灯において、拡声プレート３は、複数の立設脚部を有した円板又は多角形板からなり、板中央に凹状の窪み部３０を有すると共に窪み部３０には多数の小孔３Ｈが形成されることが好ましい。中央の拡声プレートの上面窪みと多孔穴とにより、報知音が効率的に拡声される。 (3) In the notification lamp, the loudspeaker plate 3 is composed of a circular plate or a polygonal plate having a plurality of standing legs, and has a concave recess 30 at the center of the plate, and the recess 30 has a large number of small portions. It is preferable that the hole 3H is formed. The notification sound is efficiently amplified by the upper surface depression and the perforated hole of the central speaker plate.

また拡声プレート３の窪み部３０の中央部分にはさらに上面が凹状に窪んだ、矩形状の第二窪み３０１が形成され、また複数の立設脚部間には側方へ解放した側部開口３２０が複数個形成される。
矩形状の第二窪み３０１によって拡声プレート３の中央の窪み部３０の一部が薄板で構成され、グローブ２の中央孔２０からの報知音を薄板部分で乱反射させることができる。また、この乱反射した報知音を、複数の側部開口３２０から外部へ発生させることで、ドーム形状の周囲へ報知音を拡声させた状態で発音することができる。また、複数の小孔３Ｈや側部開口３２０によって、グローブ２内の放熱機能を備えたものとなる。なお、拡声プレート３がアルミニウム金属などの導電性材からなる場合、さらに放熱機能を備えたものとなる。 In addition, a rectangular second recess 301 whose upper surface is further recessed is formed in the central portion of the recess 30 of the loudspeaker plate 3, and a side opening opened laterally between the plurality of standing legs. A plurality of 320 are formed.
Part of the central depression 30 of the loudspeaker plate 3 is formed of a thin plate by the rectangular second depression 301, and the notification sound from the central hole 20 of the globe 2 can be irregularly reflected by the thin plate portion. In addition, by generating the irregularly reflected notification sound from the plurality of side openings 320 to the outside, the notification sound can be generated in a state where the notification sound is amplified around the dome shape. In addition, the plurality of small holes 3H and the side openings 320 provide a heat dissipation function in the globe 2. In addition, when the loudspeaker plate 3 is made of a conductive material such as aluminum metal, it further has a heat dissipation function.

すなわち、拡声プレート３が複数の立設脚部を有し、板中央に凹状の窪み部３０を有した円板又は多角形板からなることで、中央孔の防水化だけでなく、中央孔２０からの拡声と放熱機能を備えた報知灯となる。 That is, the loudspeaker plate 3 has a plurality of standing leg portions and is made of a circular plate or a polygonal plate having a concave depression 30 at the center of the plate, so that not only the central hole is waterproofed but also the central hole 20. It becomes an information lamp equipped with a loud sound and a heat dissipation function.

（４）前記報知灯において、本体部１は、短筒体の上部に、拡散プリズム及び発光素子を備えた報知光の発光基板１２を有すると共に、短筒体の内部に、発光素子の発光及び防水スピーカの報知音を制御する制御基板１１を有し、これら発光基板及び制御基板とによって二重に離間配置された発光装置を構成することが好ましい。 (4) In the notification lamp, the main body 1 has a light emitting substrate 12 for notification light provided with a diffusion prism and a light emitting element at the upper part of the short cylindrical body, and the light emission of the light emitting element and the inside of the short cylindrical body. It is preferable to configure a light emitting device that has a control board 11 that controls the notification sound of the waterproof speaker and that is spaced apart from the light emitting board and the control board.

動作時に比較的高熱となる発光基板１２の下方に、高熱化しない制御基板１１が短筒内収容されることで、上下二重の離間基板によって発光装置を構成する。グローブ内に開放した上部に発熱基板を設け、非発熱基板と分離構成することで、上部では動作時にグローブ側へ排熱しやすく、内部に浸水しにくい構造となっている。発光基板１２はその上面に、基板配線された複数の発光素子を、板中心の周りに複数個離間配置してなると共に、この発光素子の上部を覆って、透明の三角柱体を放射状に組み合わせた上方凸状の立体からなる拡散プリズム１３が取り付けられる。これにより、万一発光基板１２まで浸水した場合でも、より下方への浸水を抑制することができる。すなわち、万一発光部へ浸水した場合でも発光基板１２上面の大部分を拡散プリズム１３が覆うことで基板の下方への浸水を妨げることができる。一方、拡散プリズム１３の三角柱体によって、発光素子の光をグローブ内で所定の方向を中心として拡散させるプリズム拡散効果を得ることができる。 The control board 11 that does not increase in heat is housed in the short cylinder below the light emitting board 12 that becomes relatively hot during operation, so that the light emitting device is constituted by the upper and lower double spaced boards. By providing a heat generating substrate in the upper part opened in the globe and separating from the non-heat generating substrate, the upper part is easy to exhaust heat to the glove side during operation, and it is difficult for water to enter inside. The light-emitting substrate 12 has a plurality of light-emitting elements wired on the top surface of the light-emitting substrate 12 spaced apart from each other around the center of the plate, and a transparent triangular prism body is radially combined to cover the top of the light-emitting element. A diffusion prism 13 made of an upwardly convex solid is attached. As a result, even when the light emitting substrate 12 is submerged, it is possible to suppress further downward water immersion. In other words, even if the light emitting unit is submerged, the diffusion prism 13 covers most of the upper surface of the light emitting substrate 12 so that water can be prevented from entering below the substrate. On the other hand, the triangular prism body of the diffusing prism 13 can provide a prism diffusing effect that diffuses light from the light emitting element around a predetermined direction in the globe.

（５）前記報知灯において、本体部１は、短筒体の下部の下枠１５内に、三方又は四方の部分方形状の嵌め込み枠１６１，１６２を設けると共に、当該嵌め込み枠に嵌め込まれる箱状の取付け板６を具備し、さらに、嵌め込み枠に嵌め込まれた取付け板を固定する固定ビス６２Ｂを具備した取付け構造を有することが好ましい。
この取付け構造は、取付け板６の周囲と下枠１５との間に下部空間１５０が形成される。またさらに、取付け板ないし嵌め込み枠の一部には、嵌め込まれた取付け板ないし嵌め込み枠の対応部分を互いに係止させる係止構造が設けられることが好ましい。 (5) In the notification lamp, the main body 1 is provided in the lower frame 15 at the lower part of the short cylindrical body with the three- or four-side partial fitting frames 161 and 162 and the box shape fitted into the fitting frame. It is preferable to have an attachment structure provided with a fixing screw 62B for fixing the attachment plate fitted in the fitting frame.
In this attachment structure, a lower space 150 is formed between the periphery of the attachment plate 6 and the lower frame 15. Furthermore, it is preferable that a part of the mounting plate or the fitting frame is provided with a locking structure for locking corresponding portions of the fitted mounting plate or the fitting frame.

すなわち、本体部１の下枠１５の底面形状よりも一回り小さな取付け板６をはめ込む取付け構造によって、取付け用のアングル部品や、壁面又は天井面から突出したりはみ出したりする部材を有することがない。このため、本発明の一体型の報知灯を、取付け面に沿って体裁よく取り付けることができる。また下枠内一杯に取付け板６が設けられるのではなく、下枠内と取付け板６との間に弦と円弧で囲われた部分円からなる下部空間１５０が複数個形成される。この下枠１５と下部空間１５０の形成によって、取付け面との間に止水ないし浸水防止スペースが確保され、取付け面の防水機能に優れたものとなる。 That is, the mounting structure that fits the mounting plate 6 that is slightly smaller than the bottom surface shape of the lower frame 15 of the main body 1 does not have an angle component for mounting or a member that protrudes or protrudes from the wall surface or ceiling surface. For this reason, the integrated notification lamp of this invention can be attached with good appearance along the attachment surface. In addition, the mounting plate 6 is not provided in the entire lower frame, but a plurality of lower spaces 150 formed of partial circles surrounded by strings and arcs are formed between the lower frame and the mounting plate 6. By forming the lower frame 15 and the lower space 150, a water stoppage or flooding prevention space is ensured between the mounting surface and the waterproof function of the mounting surface is excellent.

本発明は上記手段を講じることで、スピーカと報知灯とを上部に一体化させたコンパクトな構成とすることで、報知音を取り付け面の正面（法線）側ないしその周囲へ効率的に拡声することができ、また、報知光をその周囲から効率的に拡光することができる。また、スピーカと報知灯とを上部に一体化したコンパクトな構成でありながら、止水性に優れた報知灯をなすことができる。 In the present invention, by adopting the above-mentioned means, the speaker and the notification lamp are integrated into a compact structure, so that the notification sound can be efficiently amplified on the front surface (normal line) side of the mounting surface or around it. In addition, it is possible to efficiently spread the notification light from its surroundings. Moreover, although it is the compact structure which integrated the speaker and the notification lamp on the upper part, the notification lamp excellent in water-stopping property can be made.

本発明の主な特徴として、図２に示すように、本体部１は、短筒体の下部の下枠１５内に、三方の部分方形状の嵌め込み枠１６１，１６２を設けると共に、当該嵌め込み枠に嵌め込まれる箱状の取付け板６を具備し、さらに、嵌め込み枠を貫通して嵌め込まれた取付け板を外方からビス固定する固定ビス６２Ｂを具備した取付け構造を有する。この取付け構造はまた、取付け板６の周囲と下枠１５との間に下部空間１５０が形成される。すなわち、本体部１の下枠１５の底面形状よりも一回り小さな取付け板６をはめ込む取付け構造によって、取付け用のアングル部品や、壁面又は天井面から突出したりはみ出したりする部材を有することがない。 As a main feature of the present invention, as shown in FIG. 2, the main body 1 is provided with three partial rectangular fitting frames 161 and 162 in the lower frame 15 at the lower part of the short cylindrical body, and the fitting frame. And a mounting structure having a fixing screw 62B for fixing the mounting plate inserted through the fitting frame from the outside. In this mounting structure, a lower space 150 is also formed between the periphery of the mounting plate 6 and the lower frame 15. That is, the mounting structure that fits the mounting plate 6 that is slightly smaller than the bottom surface shape of the lower frame 15 of the main body 1 does not have an angle component for mounting or a member that protrudes or protrudes from the wall surface or ceiling surface.

このため、本発明の一体型の報知灯を、取付け面に沿って体裁よく取り付けることができる。また下枠内一杯に取付け板６が設けられるのではなく、下枠内と取付け板６との間に弦と円弧で囲われた部分円からなる下部空間１５０が複数個形成される。この下枠１５と下部空間１５０の形成によって、取付け面との間に止水ないし浸水防止スペースが確保され、取付け面の防水機能に優れたものとなる。 For this reason, the integrated notification lamp of this invention can be attached with good appearance along the attachment surface. In addition, the mounting plate 6 is not provided in the entire lower frame, but a plurality of lower spaces 150 formed of partial circles surrounded by strings and arcs are formed between the lower frame and the mounting plate 6. By forming the lower frame 15 and the lower space 150, a water stoppage or flooding prevention space is ensured between the mounting surface and the waterproof function of the mounting surface is excellent.

またさらに、取付け板及び嵌め込み枠の一部であって、固定ビス６２Ｂのビス固定方向と逆の位置には、嵌め込まれた取付け板ないし嵌め込み枠の対応部分を互いに係止させる係止突起構造が設けられる。実施例では短距の嵌め込み枠１６２の先側に、先折れ片からなる係止突起１６Ｔが設けられると共に、取付け板６には、これに係止する係止孔６Ｈが設けられる。 Furthermore, a locking projection structure that is a part of the mounting plate and the fitting frame, and that locks the corresponding portions of the fitting plate and the fitting frame that are fitted to each other at a position opposite to the screw fixing direction of the fixing screw 62B. Provided. In the embodiment, a locking projection 16T made of a bent piece is provided on the front side of the short-distance fitting frame 162, and a locking hole 6H for locking to the mounting plate 6 is provided in the mounting plate 6.

本発明の主な特徴として、図３に示すように、グローブ２の頂部には中央孔２０が形成されると共に、中央孔２０の周囲近傍の下部のグローブ２内側面に防水スピーカ４が固定され、中央孔の周囲近傍の上部のグローブ２外面に拡声プレート３が固定される。警告音の作動時には、防水スピーカ音が中央孔から拡声プレートによって拡声されることで、警告音を報知する。 As a main feature of the present invention, as shown in FIG. 3, a central hole 20 is formed at the top of the globe 2, and a waterproof speaker 4 is fixed to the inner surface of the lower globe 2 near the periphery of the central hole 20. The loudspeaker plate 3 is fixed to the outer surface of the upper globe 2 near the periphery of the central hole. When the warning sound is activated, the waterproof speaker sound is amplified by the loudspeaker plate from the central hole, thereby notifying the warning sound.

また、前記防水スピーカ４は、上方拡径した円錐状のフレームと、フレームの上部周囲から円錐内部にかけて取り付けられたすり鉢状の振動板と、振動板中央に取り付けられたセンターキャップとを、連続した防水構造で有すると共に、フレームの上部周囲に環状の止水材４Ｇが係止される。図４ないし５に示すように、防水スピーカ４の周囲を上方へ圧着する固定具５によって前記フレームの上部周囲の環状の止水材４Ｇがグローブ２の中央孔２０の周囲に圧着することで、上方からの浸水を確実に抑制する止水構造をなす。 The waterproof speaker 4 includes a conical frame having an enlarged diameter, a mortar-shaped diaphragm attached from the upper periphery of the frame to the inside of the cone, and a center cap attached to the center of the diaphragm. While having a waterproof structure, an annular water stop material 4G is locked around the upper part of the frame.

The light emitter 13 is fixed. When the warning light is activated, the eight light emitting elements emit light or blink in unison in order along the circumferential direction, and this light is reflected and emitted by the prism light emitter, thereby turning the warning light into a rotating lamp-like manner. Or notify the blinking indicator light.

以下、実施例の各構成について詳述する。 Hereinafter, each structure of an Example is explained in full detail.

（本体部１）本体部１は、下面を取り付け面として内部に上下二段の孔あき仕切り板を設け、上方に開放した円形断面の短筒体からなると共に、その上部に、プリズム放光体１３及び発光素子を含む発光基板を備え、その内部に、発光素子の発光及び防水スピーカの発声を制御する制御基板を備える。これら発光基板、制御基板及び各基板の附属品であるプリズム放光体１３によって発光装置が構成される。
また本体部１は、短筒体の上部に、拡散プリズム及び発光素子を備えた報知光の発光基板１２を有すると共に、短筒体の内部に、発光素子の発光及び防水スピーカの報知音を制御する制御基板１１を有し、これら発光基板及び制御基板とによって二重に離間配置された発光装置を構成する。基板上面は図６に示すように一部（図６の左部）が直線的に欠けた円板からなり、発音種類の切り替えスイッチ１２Ｓとボリュームスイッチ１２Ｖが端部に備えられると共に、矩形の中央孔１３０が設けられる。プリズム放光体１３は、中央孔１３０の周りを覆う、皿状の中央多角形板１３３と中央多角形板１３３の周囲に張り出した連接板１３２と、４つの三角柱が連接された８個の複合プリズム体１３１とを具備して一体的に構成される。 (Main Body 1) The main body 1 is composed of a short cylindrical body having a circular cross section opened on the upper side and provided with two upper and lower perforated partition plates with the lower surface as an attachment surface. 13 and a light emitting board including the light emitting element, and a control board for controlling the light emission of the light emitting element and the sound output of the waterproof speaker. The light emitting device is constituted by the light emitting substrate, the control substrate, and the prism light emitter 13 which is an accessory of each substrate.
The main body 1 has a light emitting substrate 12 for notification light including a diffusing prism and a light emitting element at the upper portion of the short cylindrical body, and controls light emission of the light emitting element and notification sound of the waterproof speaker inside the short cylindrical body. The light-emitting device which has the control board 11 to be disposed and is separated from each other by the light-emitting board and the control board is configured. As shown in FIG. 6, the upper surface of the substrate is formed of a disc with a part (left part of FIG. 6) that is linearly cut off, and is provided with a sound generation type changeover switch 12S and a volume switch 12V at its end, A hole 130 is provided. The prism light emitter 13 includes a plate-shaped central polygonal plate 133 covering the central hole 130, a connecting plate 132 projecting around the central polygonal plate 133, and eight composites in which four triangular prisms are connected. The prism body 131 is provided and is configured integrally.

動作時に比較的高熱となる発光基板１２の下方に、高熱化しない制御基板１１が短筒内収容されることで、上下二重の離間基板によって発光装置を構成する。グローブ内に開放した上部に発熱基板を設け、非発熱基板と分離構成することで、上部では動作時にグローブ側へ排熱しやすく、内部に浸水しにくい構造となっている。発光基板１２はその上面に、基板配線された複数の発光素子を、板中心の周りに複数個離間配置してなると共に、この発光素子の上部を覆って、透明の三角柱体を放射状に組み合わせた上方凸状の立体からなる拡散プリズム１３が取り付けられる。これにより、万一発光基板１２まで浸水した場合でも、より下方への浸水を抑制することができる。すなわち、万一発光部へ浸水した場合でも発光基板１２上面の大部分を拡散プリズム１３が覆うことで基板の下方への浸水を妨げることができる。一方、拡散プリズム１３の三角柱体によって、発光素子の光をグローブ内で所定の方向を中心として拡散させるプリズム拡散効果を得ることができる。 The control board 11 that does not increase in heat is housed in the short cylinder below the light emitting board 12 that becomes relatively hot during operation, so that the light emitting device is constituted by the upper and lower double spaced boards. By providing a heat generating substrate in the upper part opened in the globe and separating from the non-heat generating substrate, the upper part is easy to exhaust heat to the glove side during operation, and it is difficult for water to enter inside. The light-emitting substrate 12 has a plurality of light-emitting elements wired on the top surface of the light-emitting substrate 12 spaced apart from each other around the center of the plate, and a transparent triangular prism body is radially combined to cover the top of the light-emitting element. A diffusion prism 13 made of an upwardly convex solid is attached. As a result, even when the light emitting substrate 12 is submerged, it is possible to suppress further downward water immersion. In other words, even if the light emitting unit is submerged, the diffusion prism 13 covers most of the upper surface of the light emitting substrate 12 so that water can be prevented from entering below the substrate. On the other hand, the triangular prism body of the diffusing prism 13 can provide a prism diffusing effect that diffuses the light of the light emitting element around a predetermined direction in the globe.
