Description

本発明の実施形態は、光源と電源部とを接続線で接続する照明装置に関する。 An embodiment of the present invention relates to a lighting device that connects a light source and a power supply unit with a connecting line.

従来、天井板に設けられた開口部に埋め込み設置するダウンライト等の照明装置がある。この照明装置では、放熱体の内側に配置される光源と放熱体の外側に配置または別置きされる電源部とを接続線で電気的に接続している。接続線は、放熱体の側面から放熱体の外側に引き出していることが多い。 Conventionally, there are lighting devices such as downlights that are embedded and installed in an opening provided in a ceiling plate. In this lighting device, a light source arranged inside the radiator and a power supply unit arranged outside the radiator or separately are electrically connected by a connecting line. The connecting line is often drawn from the side surface of the radiator to the outside of the radiator.

ところで、放熱性の向上を図るには、放熱体の径を天井板の開口部に挿入可能範囲内で大きくして放熱面積を増加させることが好ましいが、この場合、天井板の開口部に放熱体を挿入する際に、接続線が天井板に引っ掛かりやすくなって施工しにくくなるため、放熱体の径をあまり大きくすることができず、放熱性の向上が難しい。 By the way, in order to improve the heat dissipation, it is preferable to increase the diameter of the radiator within the range that can be inserted into the opening of the ceiling plate to increase the heat dissipation area. In this case, the heat is dissipated to the opening of the ceiling plate. When inserting the body, the connecting wire is easily caught on the ceiling plate, making it difficult to construct, so the diameter of the radiator cannot be made too large, and it is difficult to improve the heat dissipation.

このような作業において、電源部12に対して灯体11が吊り下がったり、灯体11に対して電源部12が吊り下がったりすることがある。このとき、灯体11（吊り具固定部39）と電源部12との間の吊り具14の長さL1は、灯体11（接続線固定部38）と電源部12との間の接続線13の長さL2よりも短い関係にあるため、灯体11または電源部12が吊り下げ状態となっても吊り具14を介して吊り下げることになり、接続線13やこの接続線13の接続箇所等に負荷が加わることがない。 In such work, the lamp body 11 may be suspended from the power supply unit 12, or the power supply unit 12 may be suspended from the lamp body 11. At this time, the length L1 of the hanger 14 between the lamp body 11 (hanging tool fixing portion 39) and the power supply unit 12 is the connecting line between the lamp body 11 (connecting line fixing portion 38) and the power supply unit 12. Since the length of 13 is shorter than L2, even if the lamp body 11 or the power supply unit 12 is suspended, it will be suspended via the hanger 14, and the connection line 13 and the connection line 13 will be connected. No load is applied to the parts.

さらに、放熱体17の同じ領域に接続線固定部38と吊り具固定部39とが設けられているため、灯体11または電源部12が吊り下げ状態となっても、確実に吊り具14を介して吊り下げることになり、接続線13やこの接続線13の接続箇所等に負荷が加わることがなく、しかも、接続線13と吊り具14とがまとまりやすく、作業しやすい。 Further, since the connection line fixing portion 38 and the hanger fixing portion 39 are provided in the same area of the radiator body 17, even if the lamp body 11 or the power supply portion 12 is in a suspended state, the hanger 14 can be reliably used. Since it is suspended via the connection line 13, no load is applied to the connection line 13 or the connection point of the connection line 13, and the connection line 13 and the hanger 14 are easily organized and work is easy.

Since 13 can be arranged along the wiring groove 43 so that the connecting wire 13 does not protrude from the side surface of the radiator body 17, the fin 27 is not sharply cut and the connecting wire 13 does not interfere with the construction and dissipates heat. It is possible to improve the workability and workability.

さらに、配線溝部43は、隣り合うフィン27間に、そのフィン27に沿って設けられるため、フィン27を大きく削ることなく、接続線13を配置でき、放熱体17の放熱性を確保することができる。 Further, since the wiring groove portion 43 is provided between the adjacent fins 27 along the fins 27, the connection line 13 can be arranged without significantly cutting the fins 27, and the heat dissipation of the radiator body 17 can be ensured. can.

また、灯体11（吊り具固定部39）と電源部12との間の吊り具14の長さL1は、灯体11（接続線固定部38）と電源部12との間の接続線13の長さL2よりも短い関係にあるため、灯体11または電源部12が吊り下げ状態となっても吊り具14を介して吊り下げることになり、接続線13やこの接続線13の接続箇所等に負荷が加わることがなく、接続不良などの発生を防止することができる。 Further, the length L1 of the hanging tool 14 between the lamp body 11 (hanging tool fixing portion 39) and the power supply unit 12 is the connecting line 13 between the lamp body 11 (connecting line fixing portion 38) and the power supply unit 12. Since the length is shorter than L2, even if the lamp body 11 or the power supply unit 12 is suspended, it will be suspended via the hanger 14, and the connection line 13 and the connection point of this connection line 13 will be suspended. It is possible to prevent the occurrence of poor connection, etc. without applying a load to the above.

さらに、放熱体17の同じ領域に接続線固定部38と吊り具固定部39とを設けているため、灯体11または電源部12が吊り下げ状態となっても、確実に吊り具14を介して吊り下げることになり、接続線13やこの接続線13の接続箇所等に負荷が加わることがなく、しかも、接続線13と吊り具14とがまとまりやすく、作業しやすくできる。 Further, since the connection line fixing portion 38 and the hanger fixing portion 39 are provided in the same area of the radiator body 17, even if the lamp body 11 or the power supply portion 12 is in a suspended state, the hanger 14 is surely used. The connection line 13 and the connection point of the connection line 13 are not loaded, and the connection line 13 and the hanger 14 are easily organized, which makes the work easier.

さらに、吊り具固定部39は、接続線固定部38よりも放熱体17の外側位置に配置されているため、吊り具14を介して灯体11が吊り下がる際、吊り具14によって接続線13に負荷を加えるのを防止できる。 Further, since the hanging tool fixing portion 39 is arranged at a position outside the radiator body 17 with respect to the connecting line fixing portion 38, when the lamp body 11 is suspended via the hanging tool 14, the connecting line 13 is provided by the hanging tool 14. It is possible to prevent the load from being applied to the body.

さらに、吊り具固定部39よりも放熱体17の内側位置に配置されている接続線固定部38には、接続線固定部材63が配置される一対の位置決め壁部41を設けているため、接続線固定部材63を位置決めできるとともに、ねじ68の操作によって接続線固定部材63が回転するのを規制でき、作業性を良好にできる。 Further, since the connection line fixing portion 38 arranged at the inner position of the radiator body 17 with respect to the hanger fixing portion 39 is provided with a pair of positioning wall portions 41 in which the connection line fixing member 63 is arranged, the connection is made. The wire fixing member 63 can be positioned, and the rotation of the connecting wire fixing member 63 can be restricted by the operation of the screw 68, so that workability can be improved.
