Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a starting device for a fluorescent lamp connected to a single-cap compact fluorescent lamp or the like.

[Conventional technology]

Figure 5 shows a Mitsubishi Electric fluorescent lamp stand (model name).
BS3051) is a schematic structural diagram. In this diagram,
Reference numeral 1 designates a single-end compact fluorescent lamp, 2 a base with four base pins 3 protruding, and 4 a socket for the fluorescent lamp 1, the upper surface of the lamp base accommodating portion having an oval shape. Further, 5 is four base wires pulled out from the bottom surface of the socket 4, and 6 is a converter that converts the commercial AC voltage of the commercial AC power supply 7 into a high frequency voltage of about several tens of kilohertz, and lights the fluorescent lamp 1 with this high frequency voltage. The electronic ballast 8 is a starting capacitor as a starting component that is arranged separately from the electronic ballast 6. Further, numeral 9 indicates the main body of the fluorescent lamp stand that houses the above-mentioned parts.

FIG. 6 shows a wiring diagram of the fluorescent lamp stand shown in FIG. One side of each of the filaments 1a, 1b of 1 is connected, and the filaments 1a, 1b are connected to each other.
The other side of each of 1b is connected to a lead wire 8a of a starting capacitor 8 via an outlet wire 5.

[Problem that the invention seeks to solve]

In the fluorescent lamp having such a configuration, by separating the starting capacitor 8 from the ballast 6 and arranging it near the socket 4, only two lead wires 5 from the socket 4 are required to be wired to the ballast 6. This is particularly advantageous when the lead wire 5 passes through a thin pipe. However, on the other hand, the following problems arose.

Since the starting capacitor 8 is connected to the lead wire 5 of the socket 4 and placed near the socket 4, the area around the socket 4 in the instrument body 9 cannot be made compact.

In order to connect the lead wire 8a of the starting capacitor 8 and the outlet wire 5 of the socket 13, it is necessary to insulate this connection portion.

If the starting capacitor has a structure that touches a metal plate, take into account the possibility of damaging the surface of the starting capacitor 8 during assembly work.
surface insulation work is required.

If the structure is such that the starting capacitor 8 is not fixed to the socket 4 or the device body 9, the device body 9
The starting capacitor 8 interferes with the assembly work.

[Means for solving problems]

In the fluorescent lamp starting device according to the present invention, the lamp socket is integrally connected to the oval-shaped lamp cap accommodating portion, and the lamp socket has two opposite sides formed with a width substantially equal to the short side width of the lamp socket main body. Each side has a pair of lead wire insertion holes and a connection terminal is housed inside, and the lead wire of the starting component is inserted into the lead wire insertion hole formed on one side, and the lead wire of the starting component is inserted into the lead wire insertion hole formed on one side. Lead wires connected to the lighting circuit section are inserted into the lamp, and these lead wires are connected to connection terminals facing the lead wires.

[Effect]

In this invention, the respective lead wires from the starting component and the lighting circuit section are inserted through the lead wire insertion holes formed on the short side of the main body of the oval-shaped lamp socket. , within the range defined by a circle with the longitudinal dimension as the diameter, that is, one space created between both sides of the lamp socket and the above circle is used as the storage space for the starting parts, and the other space is used as the storage space for the leads from the lighting circuit. Can be placed within the line drawing space. Therefore, it is possible to eliminate the need for an installation space larger than the circle defined by the longitudinal dimension of each lamp, and to prevent complicated processing of the lead wires.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. In the figure, reference numeral 40 denotes a socket body, which includes an oval-shaped lamp cap accommodating portion 41 that is open at the top and has four cap pin insertion holes 10 formed in the bottom surface, and a lamp cap accommodating portion 41 on the bottom side of this lamp cap accommodating portion 41. A terminal accommodating chamber 42 communicating with the pin insertion hole 10 is integrally provided. This terminal accommodating chamber 42 includes a base accommodating section 4
The width between the side surfaces located on the short side of 1 is approximately equal to the width of the lamp accommodating portion, and furthermore, a pair of lead wire insertion holes 1 are provided on each side surface.
1 and 12 are provided. Reference numeral 15 denotes a connection terminal made of an elastic conductive material, whose upper surface side is disposed corresponding to each base pin insertion hole 10, and whose portion facing the lead wire insertion holes 11 and 12 is connected to the lead wire insertion hole 1.
The terminal structure is such that a starting component 8, which will be described later and which is inserted through terminals 1 and 12, can be quickly connected to a lead wire 8a and an outlet wire 5 which is connected to a ballast 6 and other circuit components. 8 is a starting capacitor configured as a starting component, and a pair of lead wires 8 lead out to the outside.
A is bent into an L shape, and its tip is directly inserted into the lead wire insertion hole 11 provided on the side of the socket body 40, and connected to the connection terminal 15. As a result, the main body portion of the starting capacitor 8 is brought into contact with the side surface of the socket main body 1. 5 is an electronic ballast similar to that shown in FIG.
This is a lead wire that connects the ballast 6 consisting of an inverter circuit of a starting type using LC resonance and the connection terminal 15 inside the socket body 40. In addition, 14
is the lighting equipment itself. The above constitutes a starting socket for a fluorescent lamp.

In FIG. 3, the bottom of the short side of the socket main body 40 is projected like a flange, and the insertion hole 1 is inserted into this projecting part.
1 and 12 are shown. In this way, since the position of the starting capacitor 8 can be reliably regulated, the member 14 to which the starting device is attached
Even if the starting capacitor 8 is made of a conductive material such as a metal plate, there is an advantage that insulation between the starting capacitor 8 and the mounting member can be ensured without requiring any special insulation means.

In FIG. 4, the shape of the lead wire insertion hole 11 is semicircular with a straight part arranged on the mounting surface side (lighting device main body 14 side), and the radius is the lead wire 8a of the starting component 8.
This is the maximum size that can be inserted. With such a hole shape, the straight part of the lead wire insertion hole 11 acts to direct the lead wire 8a without significantly impairing the insertability of the lead wire 8a. If the starting parts 8 fall down, some parts of the starting parts 8 may fall off the lighting fixture body 14.
prevent contact with This is particularly effective when the starting component 8 is a capacitor with no insulation on its surface and the illumination body 14 is made of metal.

〔Effect of the invention〕

This invention is as explained above, and has the following effects.

The maximum external dimension of the starter device can be made approximately the same size as the maximum external dimension of the lamp base. This allows the starter to be placed within the space required for attaching and detaching the lamp, thereby easing restrictions on the placement of other electrical components.

The lead wires to the ballast are brought out on the opposite side to the side where the starting parts are placed, so the lead wires can be wired freely and in the maximum space without being obstructed by the starting parts, and contact between the output wire and the starting parts is taken into account. You don't have to.

If the starting parts are lead wire type capacitors, connecting the starting parts to the socket will be easier by making the connection terminal of the socket a quick connection type.
Fixation can be made easier.
