The substrate holder 9 is provided with a light diffusing cover 15 as shown in FIG.
LED照明装置1は、以上のような構成を有するので、LED照明装置1の現場での組み立ては、図3に示すように、例えば、天井16に取り付けられたベース3に対して、電源装置6及びLED基板11が装着された状態の基板ホルダ9及び拡散カバー15で構成される光源ユニット4を、矢印A方向に移動させる形で装着し、取り付けることで行う。なお、こうした組立態様は、本発明の要点では無く、各種の態様が考えられる。
Since the LED lighting device 1 has the above-described configuration, the assembly of the LED lighting device 1 in the field is performed, for example, with respect to the base 3 attached to the ceiling 16 as shown in FIG. The light source unit 4 composed of the substrate holder 9 and the diffusion cover 15 with the LED substrate 11 mounted thereon is mounted and attached in such a manner that it moves in the direction of arrow A. Such an assembly mode is not the main point of the present invention, and various modes can be considered.
光源ユニット4ベース3に取り付ける際に、図2に示すように、ベース3の配線取り入れ孔3bを介して天井16側から伸延して来ているアース線付きの3芯電源ケーブル2の先端を前述したように、基板ホルダ9に設けられた端子台12に接続し、電源ケーブル2から端子台12を介して直流電源装置6へ電力を供給しうるようにすると共に、電源ケーブル2のアース線を端子台12の図示しないアース端子に接続する。すると、基板ホルダ9の直流電源装置6及びLED基板11のアースは、3芯電源ケーブル2を介してアースに接続される。
When the light source unit 4 is attached to the base 3, as shown in FIG. 2, the tip of the three-core power cable 2 with the ground wire extending from the ceiling 16 side through the wiring intake hole 3b of the base 3 is described above. As described above, it is connected to the terminal block 12 provided on the substrate holder 9 so that power can be supplied from the power cable 2 to the DC power supply device 6 through the terminal block 12, and the ground wire of the power cable 2 is connected. The terminal block 12 is connected to a ground terminal (not shown). Then, the DC power supply device 6 of the substrate holder 9 and the ground of the LED substrate 11 are connected to the ground via the three-core power cable 2.
こうして電源ケーブル2を端子台12に接続した後、基板ホルダ9を図3矢印A方向に移動させてベース3に取り付けるが、この際、基板ホルダ9に立設されたアース接続金具13のピン13aが、ベース3設けられたナット13bに陥入係合することで、ベース3のアースはアース接続金具13を介して基板ホルダ9側のLED基板11及び直流電源装置6内の図示しない電源基板のアースと導通し、更に端子台12のアース端子と導通することとなる。
After connecting the power cable 2 to the terminal block 12 in this way, the substrate holder 9 is moved in the direction of arrow A in FIG. 3 and attached to the base 3. At this time, the pin 13a of the ground connection fitting 13 erected on the substrate holder 9 is attached. However, the base 3 is grounded and engaged with the nut 13 b provided on the base 3, whereby the ground of the base 3 is connected to the LED board 11 on the board holder 9 side and the power supply board (not shown) in the DC power supply device 6 via the ground connection fitting 13. Conduction with the ground and further with the ground terminal of the terminal block 12 are conducted.
すると、既に述べたように、端子台12は、3芯電源ケーブル2が接続されて、当該3芯電源ケーブル2を介して外部のアースに接続されているので、ベース3も同様に3芯電源ケーブル2を介してアースされることとなる。
Then, as already described, since the terminal block 12 is connected to the external ground via the 3-core power cable 2 and the 3-core power cable 2 is connected, the base 3 is similarly connected to the 3-core power supply. The cable 2 is grounded.
既に説明したように、光源ユニット4のベース3への装着に際しては、アース線が設けられた3芯電源ケーブル2を、基板ホルダ9に設けられた端子台12に接続するだけで、直流電源装置6への3芯電源ケーブル2の接続と、当該3芯電源ケーブル2を介した直流電源装置6とLED基板11のアースと、ベース3のアース接続が完了するので、端子台5をベース3に設けた場合のように、端子台5と直流電源装置6を接続する接続ケーブル7の接続作業を行う必要が無くなり、組立作業を効率的に行うことが出来る。
As already described, when the light source unit 4 is mounted on the base 3, the DC power supply device can be obtained simply by connecting the three-core power cable 2 provided with the ground wire to the terminal block 12 provided on the substrate holder 9. Since the connection of the three-core power cable 2 to 6, the grounding of the DC power supply device 6 and the LED board 11 and the base 3 via the three-core power cable 2 is completed, the terminal block 5 is attached to the base 3. As in the case where it is provided, it is not necessary to perform the connection work of the connection cable 7 for connecting the terminal block 5 and the DC power supply device 6, and the assembly work can be performed efficiently.
なお、アース接続金具13は、ベース3のアースと基板ホルダ9側のアースを接続することが出来ればどのような構成でも良いが、光源ユニット4の構成要素である基板ホルダ9をベース3側に移動させる基板ホルダ9のベース3への接近装着動作(従って、図3の矢印A.B方向への移動)により、アース接続金具13の接続動作が行われるように構成することが重要である。それには、基板ホルダ9の接近装着動作方向である図3の矢印A,B方向への移動により、アース接続金具13の電気的な接続・接続解除が可能な機構を備えることが望ましい。例えば、ピンジャック方式、板バネによる圧着方式等が考えられるが、それだけに限るものではない。
The ground connection fitting 13 may have any configuration as long as the ground of the base 3 and the ground on the substrate holder 9 side can be connected, but the substrate holder 9 that is a component of the light source unit 4 is placed on the base 3 side. It is important that the connection operation of the ground connection fitting 13 is performed by the close attachment operation of the substrate holder 9 to be moved to the base 3 (therefore, movement in the direction of arrows AB in FIG. 3). For this purpose, it is desirable to provide a mechanism capable of electrically connecting / disconnecting the ground connection fitting 13 by moving the board holder 9 in the directions of arrows A and B in FIG. For example, a pin jack method, a pressure bonding method using a leaf spring, and the like can be considered, but are not limited thereto.
