Description

本発明は、ユニット化された蛍光灯用点灯装置及びこれを用いる照明器具に関する。   The present invention relates to a unitized fluorescent lamp lighting device and a lighting fixture using the same.

天井面に設置される引掛ローゼットと照明器具の間に介在されて使用されるリモコン受信器ユニットは周知であり、例えば特許文献１などで知られている。特許文献１のユニットは、上面に一対の引掛刃を設けた上ケースと、この上ケースと結合される下ケースと、上ケースと下ケースにより囲まれた空間に収納され、前記引掛刃から電気接続されリモコン受信部品を実装した回路基板とを備え、前記回路基板の上面側に主たる部品があり下面側は半田面を成し、弾性付勢されて上ケースの上面に突出され天井面に設置された引掛ローゼットの円弧孔に挿入可能な回り止め部材を備え、この回り止め部材を直交変換により下方に押し下げる水平方向の解除部材が前記回路基板の上面に通され、その操作端部が外側面に露出されている。

Japanese Patent Laid-Open No. 10-321038

しかし、前記解除部材は前記回路基板の上面側すなわち主たる部品がある側の面に通されているため、その解除部材が通る付近にはそのような部品を配置できなかった。そして、このようなユニットは蛍光灯用の高周波点灯回路基板を備えたものではなかったため、その回路構成が比較的単純であり、部品が配置されない空間を残すことは簡単であった。しかしながら、多数の実装部品を要する高周波点灯回路基板ではそのような許容空間が実質無く、解除部材を通すことは不可能である。本発明はこのような解決すべき課題を鑑み、高周波点灯回路基板を備えた蛍光灯用点灯装置において、点灯回路基板に沿って解除部材を通すことを可能とすることを目的とする。   However, since the release member passes through the upper surface side of the circuit board, that is, the surface on which the main component is present, such a component cannot be disposed in the vicinity of the passage of the release member. And since such a unit was not provided with the high frequency lighting circuit board for fluorescent lamps, its circuit configuration was relatively simple, and it was easy to leave a space where no parts were arranged. However, a high-frequency lighting circuit board that requires a large number of mounting parts does not have such a permissible space and cannot be passed through a release member. In view of such problems to be solved, an object of the present invention is to make it possible to pass a release member along a lighting circuit board in a lighting apparatus for a fluorescent lamp including a high-frequency lighting circuit board.

本発明を要約すると、上面に一対の引掛刃を設けた上ケースと、この上ケースと結合される下ケースと、上ケースと下ケースにより囲まれた空間に収納され、前記引掛刃から電気接続された蛍光灯用の高周波点灯回路基板とを備え、前記点灯回路基板の上面側は半田面を成し、弾性付勢されて上ケースの上面に突出され天井面に設置された引掛ローゼットの円弧孔に挿入可能な回り止め部材を備え、この回り止め部材を直交変換により下方に押し下げる水平方向の解除部材が前記点灯回路基板の上面に通され、その操作端部が外側面に露出された蛍光灯用点灯装置である。   To summarize the present invention, an upper case provided with a pair of hooking blades on the upper surface, a lower case coupled to the upper case, and a space surrounded by the upper case and the lower case are electrically connected from the hooking blade. A high-frequency lighting circuit board for a fluorescent lamp, and the upper surface side of the lighting circuit board forms a solder surface, which is elastically biased to protrude from the upper surface of the upper case and is installed on the ceiling surface. A fluorescent member having a detent member that can be inserted into the hole, a horizontal release member that pushes the detent member downward by orthogonal transformation is passed through the upper surface of the lighting circuit board, and its operation end is exposed to the outer surface It is a lighting device for a lamp.

本発明によれば、解除部材が点灯回路基板の上面すなわち半田面側に通され、多数の部品は点灯回路基板の下面側に実装されることになるため、点灯回路基板に沿って解除部材を通すことができる。なお、半田面側にチップ部品のような微小部品を半田付け実装することは解除部材を通す妨げにはならない。   According to the present invention, since the release member is passed through the upper surface of the lighting circuit board, that is, the solder surface side, and many components are mounted on the lower surface side of the lighting circuit board, the release member is disposed along the lighting circuit board. Can pass through. It should be noted that soldering and mounting a micro component such as a chip component on the solder surface side does not hinder the passage of the release member.

次に、本発明の実施形態を説明するが、それはあくまで本発明に基づいて採択された例示的な実施形態であり、本発明をその実施形態に特有な事項に基づいて限定解釈してはならず、本発明の技術的範囲は、特許請求の範囲の請求項に示した事項さらにはその事項と実質的に等価である事項に基づいて定めなければならない。   Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention should not be limitedly interpreted based on matters specific to the embodiment. The technical scope of the present invention should be determined based on the matters shown in the claims of the claims and matters substantially equivalent to the matters.

図示の実施形態は、上面に一対の引掛刃１、１を設けた上ケース２と、この上ケース２と結合される下ケース３と、上ケース２と下ケース３により囲まれた空間に収納され、前記引掛刃１、１から電気接続された蛍光灯用の高周波点灯回路基板(以下、単に点灯回路基板と称する)４とを備え、前記点灯回路基板４の上面側は半田面(図の複雑化を避けるため半田は図示せず)を成し、コイルバネ２９などで弾性付勢されて上ケース２の上面に突出され天井面２１に設置された引掛ローゼット２２の円弧孔(下面から見て円弧孔状を成す)２７に挿入可能な回り止め部材２８を備え、この回り止め部材２８を直交変換により下方に押し下げる水平方向の絶縁性の解除部材２９が前記点灯回路基板４の上面(半田面)に通され、その操作端部が外側面に露出された蛍光灯用点灯装置である。これにより、解除部材２９が点灯回路基板４の上面すなわち半田面側に通され、コンデンサ、コイル、半導体などの多数の部品３０は点灯回路基板４の下面側に実装されることになるため、点灯回路基板４に沿って解除部材２９を通すことができる。なお、半田面側にチップ部品のような微小部品を半田付け実装することは解除部材２９を通す妨げにはならない。また、解除部材２９が通る付近には半田面を配置しない方が好ましい。そして、解除部材２９は上ケース２の下面に配置される第二絶縁板６に形成した複数のガイド部３１、３２により水平方向にガイドされている。これにより、第二絶縁板６を利用した解除部材２９の安定なガイドが可能となる。また、解除部材２９の下面に沿って垂直方向の補強リブ３３を一体に形成することにより、点灯回路基板４の半田面への近接部分を極細化できる。   The illustrated embodiment is housed in an upper case 2 provided with a pair of hooking blades 1, 1 on the upper surface, a lower case 3 coupled to the upper case 2, and a space surrounded by the upper case 2 and the lower case 3. And a fluorescent lamp high-frequency lighting circuit board (hereinafter simply referred to as a lighting circuit board) 4 electrically connected from the hooking blades 1, 1, and the lighting circuit board 4 has a solder surface (shown in the drawing). In order to avoid complication, the solder is not shown in the figure. The arc hole (as viewed from the bottom surface) of the hook rosette 22 that is elastically biased by the coil spring 29 or the like and protrudes from the upper surface of the upper case 2 and is installed on the ceiling surface 21. An anti-rotation member 28 that can be inserted into the circular arc hole 27 is provided, and a horizontal insulating release member 29 that pushes the anti-rotation member 28 downward by orthogonal transformation is provided on the upper surface (solder surface) of the lighting circuit board 4. ) And its operating end is exposed to the outer surface. It has been a fluorescent lamp lighting apparatus. Accordingly, the release member 29 is passed through the upper surface of the lighting circuit board 4, that is, the solder surface side, and a large number of components 30 such as capacitors, coils, and semiconductors are mounted on the lower surface side of the lighting circuit board 4. The release member 29 can be passed along the circuit board 4. It should be noted that soldering and mounting a micro component such as a chip component on the solder surface side does not hinder the release member 29 from passing therethrough. Further, it is preferable not to arrange a solder surface in the vicinity where the release member 29 passes. The release member 29 is guided in the horizontal direction by a plurality of guide portions 31 and 32 formed on the second insulating plate 6 disposed on the lower surface of the upper case 2. Thereby, the stable guide of the cancellation | release member 29 using the 2nd insulating board 6 is attained. Further, by integrally forming the reinforcing ribs 33 in the vertical direction along the lower surface of the release member 29, a portion close to the solder surface of the lighting circuit board 4 can be made extremely fine.

そして、このようにユニット化された蛍光灯用点灯装置はその引掛刃１、１により天井面２１に設置された引掛ローゼット２２に接続固定され、前記蛍光灯用点灯装置の外周縁には蛍光灯２３を接続した蛍光灯ソケット２４を備えた照明器具本体２５が着脱可能に係止され、前記蛍光灯ソケット２４には前記蛍光灯用点灯装置の点灯出力がリード線２６を介して接続された照明器具を構成している。   Then, the fluorescent lamp lighting device unitized in this way is connected and fixed to the hooking rosette 22 installed on the ceiling surface 21 by the hooking blades 1, 1, and the fluorescent lamp lighting device has a fluorescent lamp on the outer periphery thereof. A lighting fixture body 25 having a fluorescent lamp socket 24 connected to the lamp 23 is detachably locked, and a lighting output of the fluorescent lamp lighting device is connected to the fluorescent lamp socket 24 via a lead wire 26. Make up the instrument.

図示の実施形態はまた、上面に導電性の一対の引掛刃１、１を設けた上ケース２と、この上ケース２と結合される下ケース３と、上ケース２と下ケース３により囲まれた空間に収納され、前記引掛刃１、１から電気接続された蛍光灯用の高周波点灯回路基板(以下、単に点灯回路基板と称する)４とを備え、前記上ケース２は、上面に露出される第一絶縁板５と、第一絶縁板５の下面に配置される第二絶縁板６と、第一絶縁板５と第二絶縁板６の間に挟まれた金属板７とを有し、前記点灯回路基板４は第二絶縁板６の下面に配置されたユニット化されている蛍光灯用点灯装置である。これにより、上ケース２は第一絶縁板５−金属板７−第二絶縁板６というサンドイッチ構造を備えているため、強度が向上する。また、点灯回路基板４の上面には第二絶縁板６が配置されているため、金属板７があっても内部絶縁性能も向上する。   The illustrated embodiment is also surrounded by an upper case 2 provided with a pair of conductive hooking blades 1, 1 on the upper surface, a lower case 3 coupled to the upper case 2, and the upper case 2 and the lower case 3. A high-frequency lighting circuit board (hereinafter simply referred to as a lighting circuit board) 4 for a fluorescent lamp that is housed in a space and electrically connected from the hooking blades 1, 1, and the upper case 2 is exposed on the upper surface. A first insulating plate 5, a second insulating plate 6 disposed on the lower surface of the first insulating plate 5, and a metal plate 7 sandwiched between the first insulating plate 5 and the second insulating plate 6. The lighting circuit board 4 is a unit for fluorescent lamp lighting arranged on the lower surface of the second insulating plate 6. Thereby, since the upper case 2 has a sandwich structure of the first insulating plate 5-metal plate 7-second insulating plate 6, the strength is improved. Further, since the second insulating plate 6 is disposed on the upper surface of the lighting circuit board 4, even if the metal plate 7 is present, the internal insulating performance is improved.

また、第一絶縁板５の下面に形成した複数のボス８を金属板７の上面に形成した複数の凹部９に各々位置決めしている。そうすると、金属板７を第一絶縁板５に位置決めできて組立作業が容易になる。また、凹部９の下面である突出部１０を第二絶縁板６の上面に形成した複数の第二凹部１１に各々位置決めしている。そうすると、第二絶縁板６を金属板７に位置決めできて組立作業が容易になる。また、第二凹部１１の下面である第二突出部１２を点灯回路基板４の複数の孔１３に各々位置決めしている。そうすると、点灯回路基板４を第二絶縁板６に位置決めできて組立作業が容易になる。また、引掛刃１、１に電気接続したコード１４を金属板７の上面に沿わせて点灯回路基板４の外周縁からこの点灯回路基板４に接続している。これにより、点灯回路基板４から発生する高周波がコード１４に飛び付いて引掛刃１、１から屋内配線側に帰還するノイズを抑制できる。また、第二絶縁板６に形成した窓孔１５に金属板７の下面に形成した凸部１６を挿入し、点灯回路基板４に実装した薄型パワー半導体素子などの発熱部品１７の発熱を電気絶縁性の導熱クッション部材１８を介して前記凸部１６に伝導放熱している。これにより、狭小空間に収められた発熱部品１７の発熱を効果的に放熱できるため、パワー半導体素子などの発熱部品１７の温度上昇を抑制でき、その熱的破壊を防止できる。また、第一絶縁板５の外側面から通したビス１９を下ケース３の側面を通して第二絶縁板６に螺合固定している。そうすると、ビス１９により、金属板７を挟んだ状態で第一絶縁板５と第二絶縁板６の相互固定ができるとともに、上ケース２と下ケース３の相互固定もでき、組立作業を効率化できる。また、ビス１９は第一絶縁板５の外周に形成した溝２０の底面に通されている。これにより、ビス１９が溝２０内に収まり、ビス１９の頭部に指先などを引っ掛けてしまって傷を負うというおそれがない。   Further, the plurality of bosses 8 formed on the lower surface of the first insulating plate 5 are respectively positioned in the plurality of recesses 9 formed on the upper surface of the metal plate 7. If it does so, the metal plate 7 can be positioned to the 1st insulating plate 5, and an assembly operation will become easy. Further, the protrusions 10 which are the lower surfaces of the recesses 9 are respectively positioned in a plurality of second recesses 11 formed on the upper surface of the second insulating plate 6. Then, the second insulating plate 6 can be positioned on the metal plate 7 and the assembling work becomes easy. Further, the second protrusions 12 that are the lower surfaces of the second recesses 11 are respectively positioned in the plurality of holes 13 of the lighting circuit board 4. If it does so, the lighting circuit board 4 can be positioned to the 2nd insulating board 6, and an assembly operation will become easy. A cord 14 electrically connected to the hooking blades 1, 1 is connected to the lighting circuit board 4 from the outer peripheral edge of the lighting circuit board 4 along the upper surface of the metal plate 7. Thereby, the high frequency generated from the lighting circuit board 4 jumps to the cord 14 and the noise returning from the hooking blades 1 and 1 to the indoor wiring side can be suppressed. Further, the projection 16 formed on the lower surface of the metal plate 7 is inserted into the window hole 15 formed in the second insulating plate 6 to electrically insulate the heat generated by the heat generating component 17 such as a thin power semiconductor element mounted on the lighting circuit board 4. Conductive heat is dissipated to the convex portion 16 via the heat conductive cushion member 18. As a result, the heat generated by the heat-generating component 17 housed in the narrow space can be effectively dissipated, so that the temperature rise of the heat-generating component 17 such as a power semiconductor element can be suppressed, and the thermal destruction thereof can be prevented. A screw 19 passed from the outer surface of the first insulating plate 5 is screwed and fixed to the second insulating plate 6 through the side surface of the lower case 3. Then, the first insulating plate 5 and the second insulating plate 6 can be fixed to each other with the metal plate 7 sandwiched by the screws 19, and the upper case 2 and the lower case 3 can be fixed to each other. it can. Further, the screw 19 is passed through the bottom surface of the groove 20 formed on the outer periphery of the first insulating plate 5. Accordingly, there is no risk that the screw 19 will fit in the groove 20 and a fingertip or the like will be caught on the head of the screw 19 to cause damage.

図示の実施形態はまた、上面に一対の引掛刃１、１を設けた上ケース２と、この上ケース２と結合される下ケース３と、上ケース２と下ケース３により囲まれた空間に収納され、前記引掛刃１、１から電気接続された蛍光灯用の高周波点灯回路基板(以下、単に点灯回路基板と称する)４とを備え、前記点灯回路基板４の下面側に受け台３４を介してコネクター３５を設けて、このコネクター３５を下ケース３のコネクター用開口３６に臨ませ、前記コネクター３５には前記点灯回路基板４の点灯出力が供給されている蛍光灯用点灯装置である。このように、点灯回路基板４の下面側に受け台３４を介してコネクター３５を設けたため、コネクター３５とともに点灯回路基板４を下ケース３内に収めることを容易にできる。また、受け台３４を下ケース３にビス３７ａなどで固定している。これにより、受け台３４が安定に支持され、コネクター３５がコネクター用開口３６に整合位置決めされる。また、下ケース３の下側部を下方に向けて外径のすぼまるテーパ面３７に形成し、これに対応して受け台３４の下部外側を前記テーパ面３７にガイドされるガイドテーパ面３８としている。これにより、下ケース３を上ケース２に組み付ける際の下ケース３のガイド性が向上して組み付けが容易にできる。   The illustrated embodiment also includes an upper case 2 provided with a pair of hooking blades 1, 1 on the upper surface, a lower case 3 coupled to the upper case 2, and a space surrounded by the upper case 2 and the lower case 3. A fluorescent lamp high-frequency lighting circuit board (hereinafter simply referred to as a lighting circuit board) 4 housed and electrically connected from the hooking blades 1, 1 is provided, and a cradle 34 is provided on the lower surface side of the lighting circuit board 4. A connector 35 is provided, and the connector 35 faces the connector opening 36 of the lower case 3, and the lighting device for a fluorescent lamp is supplied with the lighting output of the lighting circuit board 4. Thus, since the connector 35 is provided on the lower surface side of the lighting circuit board 4 via the cradle 34, the lighting circuit board 4 can be easily housed in the lower case 3 together with the connector 35. Further, the cradle 34 is fixed to the lower case 3 with screws 37a or the like. Thereby, the cradle 34 is stably supported, and the connector 35 is aligned and positioned in the connector opening 36. Further, the lower side of the lower case 3 is formed as a tapered surface 37 whose outer diameter is narrowed downward, and a guide tapered surface that guides the lower outer side of the cradle 34 to the tapered surface 37 correspondingly. 38. Thereby, the guide property of the lower case 3 when the lower case 3 is assembled to the upper case 2 is improved, and the assembly can be facilitated.

さらに詳述すれば、引掛刃１、１を保持した台座４０は第一絶縁板５の中央に埋め込まれ、台座４０はビス４１により金属板７に螺合固定される。ガイド部３１の底面からコイルバネ２９を介して弾性付勢された回り止め部材２８は、第二絶縁板６、金属板７、台座４０に各々通されて上ケース２の上面に少し突出される。そして、本蛍光灯用点灯装置を引掛ローゼット２２に取り付ける場合は、手で下ケース３を保持して、引掛刃１、１を引掛ローゼット２２の円弧孔２７、２７に挿入して下から見て時計回りに回転する。この回転は引掛刃１、１と円弧孔２７、２７の終端との当接でストップされ、この際に前記突出部分が円弧孔２７の端部に滑り込み係止されることにより、本蛍光灯用点灯装置の引掛ローゼット２２からの脱落が防止される。本蛍光灯用点灯装置を引掛ローゼット２２から外す際は、解除部材２９の先端を指で押し込むと、解除部材２９の内端の斜め部分４２が回り止め部材２８の基部の斜め部分４３を直交変換により下向きに押し下げるため、回り止め部材２８と円弧孔２７の係止は解除され、本蛍光灯用点灯装置を反時計回りに回転するとよい。また、受け台３４はその外側上端付近が点灯回路基板４の外周縁の切り欠き４４に軽度に係止可能になっており、受け台３４の最終的な固定は前記ビス３７ａにより成される。点灯回路基板４はビスなどで第二絶縁板６の下面に固定される。照明器具本体２５の中央孔４５に臨む下面には図示されないバネで中心方向に弾性付勢された係止部４６が装備され、照明器具本体２５を押し上げると係止部４６が一度後退してから蛍光灯用点灯装置の上面すなわち上ケース２の上面に係止される。照明器具本体２５の取り外しは係止部４６の外側にあるつまみ４７を外向きに押して係止部４７を外向きに変位させて行う。また、照明器具本体２５の下面にはグローブ４８が着脱可能に取り付けられる。なお、引掛ローゼット２２の代わりに高さの低い丸型引掛ローゼットが設置されている場合は、係止部４６は溝２０に係止される。   More specifically, the pedestal 40 holding the hooking blades 1, 1 is embedded in the center of the first insulating plate 5, and the pedestal 40 is screwed and fixed to the metal plate 7 with screws 41. The anti-rotation member 28 elastically biased from the bottom surface of the guide portion 31 via the coil spring 29 is passed through the second insulating plate 6, the metal plate 7, and the pedestal 40, and slightly protrudes from the upper surface of the upper case 2. When attaching the fluorescent lamp lighting device to the hooking rosette 22, hold the lower case 3 by hand, insert the hooking blades 1, 1 into the arc holes 27, 27 of the hooking rosette 22, and look from below. Rotate clockwise. This rotation is stopped by the contact between the hooking blades 1, 1 and the ends of the arc holes 27, 27. At this time, the projecting portion is slid into and locked to the end of the arc hole 27. The lighting device is prevented from falling off the catch rosette 22. When the fluorescent lamp lighting device is removed from the hooking rosette 22, when the tip of the release member 29 is pushed with a finger, the oblique portion 42 at the inner end of the release member 29 is orthogonally transformed with the oblique portion 43 at the base of the rotation preventing member 28. Therefore, the locking member 28 and the circular arc hole 27 are unlocked, and the fluorescent lamp lighting device may be rotated counterclockwise. Further, the upper end of the cradle 34 is lightly engageable with a notch 44 on the outer peripheral edge of the lighting circuit board 4, and the cradle 34 is finally fixed by the screw 37 a. The lighting circuit board 4 is fixed to the lower surface of the second insulating plate 6 with screws or the like. The lower surface of the luminaire body 25 facing the central hole 45 is equipped with a locking portion 46 that is elastically biased in the center direction by a spring (not shown), and when the luminaire body 25 is pushed up, the locking portion 46 is once retracted. It is locked to the upper surface of the fluorescent lamp lighting device, that is, the upper surface of the upper case 2. The luminaire main body 25 is removed by pushing the knob 47 on the outside of the locking portion 46 outward to displace the locking portion 47 outward. A glove 48 is detachably attached to the lower surface of the lighting fixture body 25. In addition, when a round hooking rosette having a low height is installed instead of the hooking rosette 22, the locking portion 46 is locked in the groove 20.
