Since the ballast insulating wall 116 of the insulating lid 100 is interposed between the terminals 134 of the terminals 134 of the terminals 134 of the 0 terminals, the insulation is completely isolated.

Next, the first case 140 is guided and positioned by the case positioning projections 4 of the reflector 1 and placed on the reflector 1 so as to cover the fixing member 100. In this state, the mounting hole 143 communicates with the case mounting hole 8 of the reflector 1 and the mounting hole 32 of the lamp holder 30, and the support arm 31 of the lamp holder 30 is held by the case mounting screw 162 while the reflector is fixed.

It is almost in contact with the periphery of 6. Finally, the assembly is completed by attaching the miniature bulb 180 and the glow starter 183 to the miniature bulb socket section 108 and the glow starter socket section 110, respectively. The lighting equipment assembled in this manner is used by being suspended from the ceiling with a chain or the like.

In the lighting equipment configured as above,
There are three main components that make up the wiring component: the reflector 1, the first case 140, and the conductive plate 50. The reflector 1 also has the function of an outer cover for a lighting fixture that has the function of reflecting light. When looking at the lighting equipment as a whole, the conventional reflector and the first or second substrate are integrated, and the number of parts can be reduced by one. In addition, there is no need to prepare a single completed intermediate part when assembling a lighting fixture, and it is possible to perform integrated production from basic parts such as conductive plates to lighting fixtures each time a lighting fixture is assembled. The inventory space is also small,
Inventory management is also easy. Furthermore, since the conductive plate 50 is placed on the protruding strips 15 of the reflector 1 formed of an insulating material, the spatial distance (the distance between the parts through the air) is However, the creepage distance (the shortest distance along the insulating material) is easier to secure than the conventional method by the height of the protrusion 15, and in particular dust can easily be It is easy to ensure safety when piled up on the bottom 2. Further, after cutting and bending the connecting portion 62 of the conductive plate 50, the connecting portion 62 is accommodated between the protrusions 15, so that cutting is easy, and at the same time, the connecting portion 62 is not completely cut off from the conductive plate 50. It is sufficient to accommodate the connecting portion 62 between the protrusions 15 while being connected to the conductive portion 50 at the wide portion, and there is no need to consider disposal of the connecting portion 62.

Furthermore, by supporting the conductive plate 50 with the protruding strips 15, the reflective plate 1 can be formed with a uniform and thin thickness, and sink marks and the like can be prevented from appearing on the outer surface of the reflective plate 1.

Furthermore, connection of the power source can be easily accomplished by simply inserting the plug 170, and no soldering work is involved.

In the above embodiment, since the insulating wall 115 of the fixing member 100 is interposed between the protrusions 15 via the circuit parts 51 of the conductive plate 50, the creepage distance between the circuit parts 51 can be increased, and at the same time, the connection Since lifting of the portion 62 is prevented, insulation is ensured at all times.
