Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture using a fluorescent lamp.

Conventionally, in this type of lighting equipment, wiring parts such as a starter socket and a switch are assembled together with a ballast into a case of the lighting equipment, and a reflector is attached to cover the bottom surface of the case. Some of the wiring parts such as a starter socket and a switch incorporated in the case are unitized as shown in, for example, Japanese Utility Model Application Publication No. 56-153022. That is, each wiring component is integrally provided on one surface side of a first substrate made of an insulating material, and a conductive portion and a circuit portion that face into each wiring component and act as a contact piece or a switch contact are provided on the other surface of the substrate. A conductive plate formed in a series is disposed, and a second substrate covers the conductive plate so that undesired charged parts are not exposed, and holds the conductive plate together with the first substrate. It is something.

However, in such a configuration,
A first board as a main component constituting wiring components separately from the case body constituting the outer shell of the lighting fixture,
Three types of parts are required: a second board and a conductive plate, and the number of parts is large, and the above wiring parts must always be prepared as one completed intermediate part when assembling the lighting equipment. However, a large amount of inventory space was required, and inventory management was also troublesome. Furthermore, in order to ensure a sufficient insulation distance between the circuit parts of the conductive plate, it is necessary to directly space the circuit parts sufficiently, and it is important to ensure a sufficient insulation distance while downsizing the conductive plate. The drawback was that it was difficult.

This invention was made in view of the above points.The number of parts is small, it is easy to perform integrated production from basic parts such as conductive plates to assembly of lighting equipment, and inventory management is easy as no special intermediate parts are required. Another object of the present invention is to provide a lighting fixture in which insulation between circuit parts of a conductive plate is reliable and easy, and a sufficient insulation distance can be ensured while reducing the size of the conductive plate.

Next, the rotor 84 is fitted onto the drive rod 87 of the switch 95, and a switch drive device 94 is separately prepared in which a coil spring 91 is disposed between the sliding arm 88 of the drive rod 87 and the rotor 84. Then, the contact piece 80 is inserted into the drawstring connecting part 90 side of this, and the contact piece support protrusion 4
2 and the switch are inserted into the cylindrical portion 41 of the switch stand 40 placed on the common contact point 53, and the contact piece 80 and the rotor 84 are brought into contact with each other. After this, the fixing member 10
0 is placed on the conductive plate 50 so that the switch driving device 94 is housed in the switch housing 101, and the fixing member mounting screw 121 is inserted into the fixing member mounting boss 19 of the reflecting plate 1 through the mounting hole 107.

Note that a soldering device and solder (both not shown) are inserted through a bottom notch 132 and a side notch 133 of the outer panel 131. Furthermore, the height of the ballast positioning rib 22 of the reflector 1 is set so that the ballast 130 is approximately horizontal after soldering. Also, stabilizer 1
Since the ballast insulating wall 116 of the insulating lid 100 is interposed between the 30 terminals 134, they are completely insulated.
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. At this time, the back of the ballast 130 and the
The bottom surface of the cylindrical portion 142 of the case 140 is several millimeters apart.

Solder hole 65 of conductive plate 50 to which 34 is soldered
portion is separated from the switch base 40. Thereafter, by inserting the plug 170 through the plug insertion hole 146 of the case 140, the engaging portion 171 is connected to the plug locking claw 100 of the fixing member 100.
The contact piece is connected to the power supply connection pin 54 of the conductive plate 50, and the stopper 172 is brought into substantially contact with the periphery of the plug insertion hole 146. Finally, bean ball 1
80 and glow starter 183 to the bulb socket part 1
08 and glow starter socket 110, assembly is completed. 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 reflective plate 1 formed of an insulating material, the insulation distance between each circuit section 51 of the conductive plate 50 is determined by the spatial distance (the shortest distance in the air) However, the creepage distance (the shortest distance along the insulator) is easier to secure than the conventional method by the height of the protrusion 15. It is easy to ensure safety when piled up. Furthermore, the conductive plate 5
After the connecting portion 62 of 0 is cut and bent, it is accommodated between the protrusions 15, so cutting is easy, and at the same time, the connecting portion 62 is not completely cut off from the conductive plate 50, but is cut at a wide portion. It is sufficient to accommodate the connecting portion 6 between the protrusions 15 while connected to the circuit portion 50.
There is no need to consider the disposal process in step 2.

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.

In the above embodiment, since the insulating wall 115 of the fixing member 100 is interposed between the protrusions 15 between 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 part 62 is prevented from rising, so that the insulation is always ensured.

Since the present invention is configured as described above, the number of parts is small, integrated production from basic parts to lighting equipment is easy, and the insulation between the circuit parts of the conductive plate is reliable and easy, and the conductive plate can be made smaller. This has the effect of providing a lighting fixture that can ensure a sufficient insulation distance.
