Abstract

<P>PROBLEM TO BE SOLVED: To prevent thermal deterioration of a cushion resin material when a main body is made of a resin. <P>SOLUTION: This ceiling-mounted luminaire is provided with the main body 4 composed by sticking, to its upper surface, the cushion resin material 2 such as a sponge resin in contact with a ceiling 1, and by mounting a lamp 3 to its undersurface. In the luminaire, the main body 4 is made of a resin; and the cushion resin material 2 is stuck throughout the upper surfaces of ribs 5 erected with space on its upper surface. That is to say, although the main body 4 made of a resin remarkably heated by heat generation of the lamp 3 cause significantly large temperature rise because its heat radiation capability is low, thermal deterioration of the cushion resin material 2 can considerably be relieved because the cushion resin material 2 never directly touch the upper surface of the main body 4. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Utility Model Registration No. 2547275

しかし、最近では高ワットのランプを使用した照明器具が主流を占め、照明器具の内部温度上昇も著しいものがある。このような場合、本体が金属製であると放熱性が良好なため、本体の上面に貼り付けられたクッション樹脂材の熱的劣化には別段、関心が払われていない。本発明は、軽量化などの観点から、本体を樹脂製とした場合にクッション樹脂材の熱的劣化を防止することに着目しようとするものである。 However, recently, lighting fixtures using high-wattage lamps have become the mainstream, and the internal temperature rise of the lighting fixtures is remarkable. In such a case, since the heat dissipation is good when the main body is made of metal, no particular attention is paid to the thermal deterioration of the cushion resin material attached to the upper surface of the main body. In view of weight reduction and the like, the present invention aims to prevent thermal deterioration of a cushion resin material when the main body is made of resin.

本発明を要約すると、上面に天井に当接するクッション樹脂材を貼り付け下面にランプを設けた本体を備えた天井取付用の照明器具であって、前記本体は樹脂製であり、その上面に間隔を置いて立設したリブの上面に渡って前記クッション樹脂材を貼り付けている照明器具である。 To summarize the present invention, there is provided a lighting fixture for ceiling mounting provided with a main body in which a cushion resin material abutting on the ceiling is attached to the upper surface and a lamp is provided on the lower surface, the main body being made of resin and spaced on the upper surface. It is the lighting fixture which has stuck the said cushion resin material over the upper surface of the rib which stood and set up.

本発明によれば、樹脂製の本体の上面に、間隔を置いて立設したリブの上面に渡ってクッション樹脂材を貼り付けているため、クッション樹脂材の熱的劣化を相当に緩和できる。また、リブはたわみやすい樹脂製の本体の補強にもなっている。 According to the present invention, since the cushion resin material is affixed to the upper surface of the resin main body over the upper surfaces of the ribs erected at intervals, the thermal deterioration of the cushion resin material can be considerably mitigated. The ribs also reinforce the flexible resin body.

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.

まず、図１、２の第一実施形態を参照して説明すると、上面に天井１に当接するスポンジ樹脂などのクッション樹脂材２を貼り付け下面にランプ３を設けた本体４を備えた天井取付用の照明器具であって、前記本体４は樹脂製であり、その上面に間隔を置いて一体的に立設したリブ５の上面に渡って前記クッション樹脂材２を貼り付けている照明器具である。すなわち、ランプ３の発熱により相当に熱せられる樹脂製の本体４は、その放熱性が悪いために温度上昇が相当に大きくなるが、クッション樹脂材２は本体４の上面には直接触れることがないため、クッション樹脂材２の熱的劣化を相当に緩和できる。また、リブ５はたわみやすい樹脂製の本体４の補強にもなっている。なお、クッション樹脂材２としてはその下面にあらかじめ粘着剤を塗布したものを用い、リブ５の上端に粘着貼り付けするとよい。 First, referring to the first embodiment of FIGS. 1 and 2, a ceiling mounting provided with a main body 4 provided with a cushion resin material 2 such as sponge resin that abuts the ceiling 1 on the upper surface and provided with a lamp 3 on the lower surface. The main body 4 is made of resin, and the cushion resin material 2 is attached to the upper surface of the rib 5 which is integrally provided upright with an interval on the upper surface thereof. is there. That is, the resin main body 4 heated considerably by the heat generated by the lamp 3 has a considerably large temperature rise due to its poor heat dissipation, but the cushion resin material 2 does not directly touch the upper surface of the main body 4. Therefore, the thermal deterioration of the cushion resin material 2 can be relieved considerably. The ribs 5 also serve to reinforce the flexible resin body 4. In addition, as the cushion resin material 2, a material in which an adhesive is previously applied to the lower surface thereof may be used, and the adhesive may be attached to the upper ends of the ribs 5.

さらに述べると、天井１に設置された引掛ローゼット６に接続されるアダプタ７を備え、本体４の下面には、前記アダプタ７が通る前記本体４の孔８に向かってコイルバネ９などで弾性付勢され前記アダプタ７に係止される被係止部１０が設けられ、リブ５は前記被係止部１０の上方付近に位置している。これにより、樹脂製の本体４において被係止部１０のある付近をリブ５により補強できて、本体４のたわみを減少でき、本体４がソフトなクッション樹脂材２を介して天井１に接する場合において、本体４のたわみ減少により被係止部１０とアダプタ７との係止関係を安定化できる効果は大きい。 More specifically, an adapter 7 connected to a hooking rosette 6 installed on the ceiling 1 is provided, and the lower surface of the main body 4 is elastically biased by a coil spring 9 or the like toward the hole 8 of the main body 4 through which the adapter 7 passes. Then, a locked portion 10 to be locked to the adapter 7 is provided, and the rib 5 is positioned near the upper portion of the locked portion 10. Thereby, in the resin main body 4, the vicinity of the locked portion 10 can be reinforced by the rib 5, the deflection of the main body 4 can be reduced, and the main body 4 contacts the ceiling 1 through the soft cushion resin material 2. In this case, the effect of stabilizing the locking relationship between the locked portion 10 and the adapter 7 by reducing the deflection of the main body 4 is great.

さらに詳述すれば、アダプタ７上面に設けた引掛刃１１は引掛ローゼット６下面の円弧孔(図示せず)に差し込み回転されて受電されている。アダプタ７は、引掛ローゼット６から受電した交流電源を単に本体４側に中継するものであってもよいし、また、アダプタ７の内部にリモコン受信回路や高周波点灯回路などを実装した点灯制御回路基板を設けて、その制御出力でランプ３を点灯制御するものであってもよい。本体４をアダプタ７に取り付けるために本体４を押し上げると、アダプタ７は本体４の孔８に通される。その際、被係止部１０はコイルバネ９の弾性付勢に抗して後退してから、図１のように、コイルバネ９の弾性付勢により突出されてアダプタ７の上面に係止される。なお、本体４をアダプタ７から取り外すときは、被係止部１０の外側下部に連設された係止解除部１２をコイルバネ９の弾性付勢に抗して外向きに変位操作するとよい。また、被係止部１０・係止解除部１２及びコイルバネ９は本体４に固定したケース１３によりスライド可能に保持されている。次に、本体４の下面に設けたソケット１４からの図示されないリード線をコネクタを介して、アダプタ７の側面のコネクタ(図示せず)に接続し、次いでソケット１４にランプ３を装着する。なお、環状の蛍光ランプであるランプ３はソケット１４以外の箇所において他の支持具３０を介して本体４に支持されるものである。そして、グローブ１５を本体４の下面に適宜手段により取り付けて施工が完了する。 More specifically, the hooking blade 11 provided on the upper surface of the adapter 7 is inserted into a circular arc hole (not shown) on the lower surface of the hooking rosette 6 and rotated to receive power. The adapter 7 may simply relay the AC power received from the hooking rosette 6 to the main body 4 side, or a lighting control circuit board in which a remote control receiving circuit, a high-frequency lighting circuit, etc. are mounted inside the adapter 7 May be provided to control the lighting of the lamp 3 with the control output. When the main body 4 is pushed up to attach the main body 4 to the adapter 7, the adapter 7 is passed through the hole 8 of the main body 4. At that time, the locked portion 10 is retracted against the elastic bias of the coil spring 9, and then protrudes by the elastic bias of the coil spring 9 and is locked to the upper surface of the adapter 7 as shown in FIG. 1. When removing the main body 4 from the adapter 7, it is preferable to operate the unlocking portion 12 connected to the outer lower portion of the locked portion 10 outwardly against the elastic bias of the coil spring 9. The locked portion 10, the lock releasing portion 12 and the coil spring 9 are slidably held by a case 13 fixed to the main body 4. Next, a lead wire (not shown) from the socket 14 provided on the lower surface of the main body 4 is connected to a connector (not shown) on the side surface of the adapter 7 via the connector, and then the lamp 3 is mounted on the socket 14. The lamp 3 which is an annular fluorescent lamp is supported by the main body 4 via another support 30 at a place other than the socket 14. Then, the glove 15 is attached to the lower surface of the main body 4 by appropriate means to complete the construction.

なお、図示した角型の引掛ローゼット６の代わりに丸型の引掛ローゼットが設置されていると、その高さは相対的に低いため、アダプタ７は図１の位置より高い位置になるため、被係止部１０はアダプタ７の上面より溝を挟んで一段低くなった係止段部１６に係止される。 If a round hook rosette is installed instead of the square hook rosette 6 shown in the figure, the height of the adapter 7 is higher than the position shown in FIG. The locking portion 10 is locked to a locking step portion 16 that is one step lower than the upper surface of the adapter 7 with a groove interposed therebetween.

次に、図３の第二実施形態は、天井１に設置され係止段部１７付きの引掛ローゼット１８を備え、本体４の下面には、前記引掛ローゼット１８が通る前記本体４の孔８に向かって弾性付勢され前記係止段部１７に係止される被係止部１０が設けられ、リブ５は前記被係止部１０の上方付近に位置している照明器具である。これにより、樹脂製の本体４において被係止部１０のある付近をリブ５により補強できて、本体４のたわみを減少でき、本体４がソフトなクッション樹脂材２を介して天井１に接する場合において、本体４のたわみ減少により被係止部１０と引掛ローゼット１８との係止関係を安定化できる効果は大きい。なお、引掛ローゼット１８は最近普及してきたタイプのものであるが、このように、前述のようなアダプタ７がなくても本発明が適用されるものである。また、引掛ローゼット１８の下面には引掛刃１１のある引掛プラグ１９が接続されて本体４側に交流電源が受電可能になっており、図示されない点灯回路などによりランプが点灯可能となっている。 Next, the second embodiment of FIG. 3 includes a hooking rosette 18 installed on the ceiling 1 and having a locking step 17, and the lower surface of the main body 4 is formed in the hole 8 of the main body 4 through which the hooking rosette 18 passes. A locked portion 10 that is elastically biased toward the locking step portion 17 is provided, and the rib 5 is a lighting fixture that is located near the locked portion 10. Thereby, in the resin main body 4, the vicinity of the locked portion 10 can be reinforced by the rib 5, the deflection of the main body 4 can be reduced, and the main body 4 contacts the ceiling 1 through the soft cushion resin material 2. In this case, the effect of stabilizing the locking relationship between the locked portion 10 and the hooking rosette 18 by reducing the deflection of the main body 4 is great. The catch rosette 18 is of a type that has recently become widespread, and thus the present invention can be applied without the adapter 7 as described above. In addition, a hooking plug 19 having a hooking blade 11 is connected to the lower surface of the hooking rosette 18 so that AC power can be received on the main body 4 side, and the lamp can be turned on by a lighting circuit (not shown).

次に、図４の第三実施形態について説明する。図４は、図１、２の照明器具を斜め天井２０に取り付けた状態を示したものである。そのための構成を要約すると、樹脂製の本体４を備えた天井取付用の照明器具であって、前記本体４には図２のように数箇所にて細筋２１で本体４につながって形成された複数のノックアウト片２２を備え、ノックアウト片２２を打ち抜いてできるノックアウト孔２３に筒体２４を差し込むことにより、筒体２４を通じてねじ２５を斜め天井２０に螺合できる照明器具である。この構成により、本体４には細筋２１で本体４につながって形成された複数のノックアウト片２２を形成しておき、通常の水平天井１の場合はノックアウト片２２を打ち抜かないで使用し、斜め天井２０の場合に打ち抜いてから、筒体２４とねじ２５により取り付けるとよい。なお、筒体２４の下端にはノックアウト孔２３より大径の鍔部２６を有し、筒体２４の内部にはねじ２５のねじ部のみ貫通でき頭部は貫通できない内周縁部２７が形成される。 Next, a third embodiment of FIG. 4 will be described. FIG. 4 shows a state in which the lighting fixtures of FIGS. 1 and 2 are attached to the oblique ceiling 20. To summarize, a lighting fixture for ceiling mounting provided with a resin-made main body 4 is formed on the main body 4 by being connected to the main body 4 at several points as shown in FIG. The lighting device includes a plurality of knockout pieces 22 and can be screwed into the oblique ceiling 20 through the cylinder body 24 by inserting the cylinder body 24 into a knockout hole 23 formed by punching out the knockout piece 22. With this configuration, the main body 4 is formed with a plurality of knockout pieces 22 connected to the main body 4 by the fine muscles 21. In the case of a normal horizontal ceiling 1, the knockout pieces 22 are used without being punched. After punching in the case of the ceiling 20, it may be attached by the cylinder 24 and the screw 25. The cylindrical body 24 has a flange portion 26 having a diameter larger than that of the knockout hole 23 at the lower end, and an inner peripheral edge portion 27 is formed inside the cylindrical body 24 so that only the screw portion of the screw 25 can be penetrated and the head portion cannot be penetrated.
