Description

Fluorescent lamp device and lighting device

The present invention relates to a fluorescent lamp device and a luminaire using one clasp fluorescent lamp.

In recent years, compact and highly efficient luminaires have become mainstream. As a light source of such a luminaire, a compact and highly efficient one-clamp fluorescent lamp is used, and a configuration in which a starter is connected to the one-clamp fluorescent lamp and installed in the lighting fixture is known.

As the prior art using such a fluorescent lamp device, the contents disclosed in Japanese Patent Laid-Open No. 64-38904 are known. This prior art has integrally provided a lamp clasp accommodating portion having an upper opening and a terminal accommodating chamber in which connection terminals are housed on the bottom side of the lamp clasp accommodating portion. It consists of a socket which forms an insertion hole, and a pair of lead wires drawn outwards to be bent in an L-shape, the leading end of which is directly inserted into one insertion hole, and is connected to a connecting terminal.

As a result, since the main body portion of the starting capacitor is supported in contact with the side surface of the socket, the maximum external dimension of the starting capacitor can be made about the same size as the maximum external dimension of the lamp clasp. The starting capacitor can be arranged in the required space, so that restrictions on the arrangement of other electrical components can be alleviated.

However, in the prior art, since only the lead wire is inserted into the insertion hole, the lead wire is also greatly shaken when the start capacitor is shaken due to vibration from the outside, so that the lead wire is disconnected and the start capacitor and the connection terminal are pulled out, There has been a problem that a failure occurs in the mechanical connection and the electrical connection between the starting capacitor and the socket, such as an excessive contact terminal causing contact failure.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and an object thereof is to provide a fluorescent lamp device and a lighting device that can be mounted on a socket with a relatively simple configuration, and which can reliably maintain mechanical and electrical connections. .

A socket having a terminal accommodation chamber having an insertion hole formed therein, a starter body and a lead wire derived from a circuit board installed in the starter body, inserted into one of the insertion holes, and connected to the terminal accommodation chamber. In a fluorescent lamp device having a starter part directly connected to a terminal, at least one insertion hole is formed with a concave portion such that the diameter of the inner side of the terminal storage chamber is smaller than the diameter of the outer side of the terminal storage chamber. It is formed continuously with the starting part main body, and has the convex part which protrudes a lead wire from the front end, and this convex part and the concave part, Fitting is characterized in that the electrically and mechanically connected to the socket by a custom.

In the present invention, unless otherwise specified, definitions and technical meanings of terms are as follows.

The starting part body is preferably formed mainly of an insulating resin material. When formed in this way, it is easy to prevent electrical defects between the circuit board provided in the starter body and the other, and at the same time, it is easy to form.

On the other hand, in the present invention, the term "electrical defects from others" refers to an electrical defect caused by contacting a circuit board or a lead wire described later with a member having conductivity other than these, or by a dust board, dust, water droplets, or the like. It is assumed to include the electrical defect which a lead wire generate | occur | produces.

The convex portion of the starting part is formed so as to hardly plastic deformation. In this way, mounting of the starting part and the socket can be made easier, and the lead wire can also be prevented from greatly shaking due to shaking of the starting part.

According to the fluorescent lamp device of the present invention, at least one of the insertion holes is formed by a concave portion such that the diameter of the inner side of the terminal storage chamber is smaller than the diameter of the outer side of the terminal storage chamber, and the starter parts are formed continuously with the starter body. Moreover, it has the convex part which the lead wire protrudes from the front end, and it connects to a socket electrically and mechanically by the fitting of this convex part and concave part, and it can connect firmly and firmly at the same time which can easily mount a starting part to a socket. As a result, it is possible to prevent the starter component from being pulled out of the socket as it is shaken, and also to prevent the lead wire itself from greatly shaking, thereby preventing contact failure between the contact terminal and the lead wire.

In addition, since the convex portion is formed in the starting part, and the lead wire protrudes from the tip thereof, it is possible to prevent the electrical failure from occurring without causing the lead wire to be exposed to the outside, thereby preventing the electrical failure more reliably. .

In addition, since the convex portion does not greatly plastically deform, shaking of the lead wire can be suppressed and electrical connection can be made more reliable.

The fluorescent lamp device of claim 2 is the fluorescent lamp device according to claim 1, wherein the convex portion is formed in a direction perpendicular to the longitudinal direction of the starter body.

The starting part of the present invention is preferably provided so that the circuit board in the starting part main body is parallel to the longitudinal direction of the starting part main body, and the lead wire extends in the vertical direction from the circuit board. In this way, the starter body can be made thinner. In addition, when the fluorescent lamp device is attached to another member such as a luminaire, the space for installing the starter component having the circuit board can be minimized, so that the degree of freedom of arrangement of the components constituting the other member can be increased.

According to the present invention, since the convex portion is formed in the direction perpendicular to the longitudinal direction of the starting part body, the space for installing the starting part can be minimized, and the convex part is formed so as to be parallel to the longitudinal direction of the starting part. Since the starter parts themselves can be arranged so as to suppress the shaking of the starting parts themselves, mechanical and electrical connections can be more reliably achieved.

It has a convex portion, which is electrically and mechanically connected to the socket by fitting the convex portion and the concave portion, so that the starting part can be easily attached to the socket and firmly connected. It is possible to prevent the socket from being pulled out, and also to prevent the lead wire itself from shaking greatly. Because, it is possible to prevent the resulting poor contact between the contact terminal and the lead wire.

Moreover, since the convex part is formed in a starting part, and a lead wire protrudes from the front end, it can prevent that a lead wire is exposed to the outside, and can prevent electrical defects more reliably.

In addition, since the convex portion does not greatly deform plastically, the lead wire can be prevented from shaking, and electrical connection can be more reliably achieved.
