The lead wire connected to the terminal block is connected. Further, the lamp holder and the power factor improving capacitor are connected by a lead wire, and the power factor improving capacitor and the terminal block are connected by a lead wire and housed in a cylindrical case. The case is filled with a resin as a filler, and the discharge lamp ballast is fixed in a tubular case with a resin as a filler. However, since it takes time for the resin as the filler to harden, the discharge lamp ballast falls down due to the spring force of the lead wire or external vibration, and the terminal portion, which is the conductive part of the discharge lamp ballast, becomes cylindrical. May come into contact with the case. Further, there is a problem that the quality is not stable, such as the position of the discharge lamp ballast being shifted, the weight balance of the lighting fixture being lost, and the occurrence of vibration.

[0009] The present invention has been made in view of the above points, and it is an object of the present invention to provide a lighting fixture of stable quality.

[0010]

In the appliance, a spacer having a ballast insertion hole into which the discharge lamp ballast is inserted and positioned and a filler communication hole into which the filler flows are provided in the cylindrical case. is there.

In the above construction, a ballast insertion hole for temporarily positioning and fixing the discharge lamp ballast is provided in the spacer having the filler communication hole, and the discharge lamp ballast is inserted into the ballast insertion hole and inserted into the cylindrical case. While being stored, the cylindrical case is filled with resin as a filler.

Since the discharge lamp ballast is temporarily fixed by the spacers, the discharge lamp ballast is subjected to the spring force of the lead wire and external vibration until the resin is cured until the resin is cured. Even if it works, the discharge lamp ballast will not fall down and no displacement will occur.
