Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a mounting structure for a round fluorescent lamp.

[Background technology]

Conventionally, as shown in FIGS. 1 and 2, the mounting structure for a round fluorescent lamp in a lighting fixture has been such that an arc-shaped support part 2 that holds the round fluorescent lamp extends from a spring leg 1. The three lamp support springs 3 are installed radially on the mounting surface 5 of the appliance main body 4 at approximately equal intervals with the openings of the arc-shaped support parts 2 facing outward. A round fluorescent lamp 6 is housed and supported in 2, and the supported state is maintained by the outward spring force of each spring leg 1, and the lamp socket 8 is fitted into the lamp pin 7 to obtain electrical connection. best known.

However, when installing this structure, first hook the round fluorescent lamp 6 onto two of the three lamp support springs 3, and then manually hold the remaining one lamp support spring 3-1. After bending it inward,
Next, the portion of the round fluorescent lamp 6 corresponding to the lamp support spring 3-1 is lifted upward (in the direction of the arrow indicated by a in the figure) to release the deflection of the lamp support spring 3-1. - Fit the support part 2 of 1 into the round fluorescent lamp 6, or after that, or the lamp support spring 3
-1, the lamp socket 8 must be inserted into the lamp pin 7, which requires time and effort to support the round fluorescent lamp, and in rare cases, when bending the lamp support spring 3-1, the lamp socket 8 must be inserted into the lamp pin 7. Lamp support spring 3
-1 may be repelled and damage the round fluorescent lamp 6, and since the lamp pin 7 is located slightly above the round fluorescent lamp 6 and is difficult to see, it is difficult to insert the lamp socket 8. Ta.

In addition, as shown in Japanese Patent Publication No. 27-2395, a pair of finger-like protrusions for engaging a light bulb is provided, one of the finger-like protrusions is provided with a contact socket, and one of the finger-like protrusions is further provided with a contact holder. It is known that the bulb is movable and biased by a spring to engage the annular bulb.In this case, the annular bulb can be easily installed, but it is difficult to guide the conductor from the contact holder. There was a problem in that the wire connection work when assembling the lighting equipment was complicated because it was connected to the internal circuit of the lighting equipment.

Furthermore, as shown in Japanese Utility Model Application Publication No. 52-15883, a ring-shaped fluorescent lamp is supported by a pair of lamp holders, and one lamp holder supports a socket. ,
The socket and the internal circuit of the lighting fixture are connected by a socket cord, and there is a problem in that the cord connection work when assembling the lighting fixture is complicated.

On the other hand, for example, the lighting device described in Japanese Patent Publication No. 39-26317 is known as a device in which a connection terminal for connecting to the internal circuit of the lighting device is provided at the base end of the lamp socket. By simply making it separable, it is easier to connect the cord when assembling the lighting equipment, but ensuring contact between the connection terminals depends only on the performance of the connection terminal itself, which improves performance when the connection is complete. If you try to do so, it becomes difficult to perform the connection work, and if you try to improve the workability of the connection, the reliability of the connection decreases.

[Purpose of invention]

The present invention has been developed in view of the above background, and provides a round fluorescent lamp that provides a reliable electrical connection without requiring any effort to connect the lamp socket and the internal circuit of the lighting device, and eliminates the risk of lamp damage. The purpose is to provide a mounting structure.

[Disclosure of invention]

The mounting structure of the round fluorescent lamp according to the present invention has a lamp socket connected to a socket connector attached to the fixture body and a lamp support spring arranged approximately symmetrically,
The lamp support spring is characterized in that the support portion holds the round fluorescent lamp, and the lamp pin of the round fluorescent lamp is inserted into the lamp socket and held by pulling the lamp pin of the round fluorescent lamp inward into the apparatus main body.

Embodiment FIGS. 3 and 4 show an embodiment according to the present invention, in which one lamp support spring 3 is mounted on the mounting surface 5.
And, in place of the lamp support spring 3, it has a pin insertion part 9 at the tip, which has approximately the same length as the spring leg 1 of the lamp support spring 3, and has a pin insertion part 9 at the proximal end, at a position symmetrical to the lamp support spring 3. A lamp socket 10 having a terminal 11 for connection to the internal circuit of the lighting device is installed diagonally toward the outside of the device body, and a socket connector 16 is installed inside the device body to make an electrical connection with the connection terminal 11. are doing. When installing a round fluorescent lamp, first insert the lamp support spring 3 so that the lamp pin 7 is aligned with the lamp socket 10.
Hang the round fluorescent lamp 6 on the lamp, pull the lamp support spring 3 slightly inward, and then, while releasing the inward tension, rotate the round fluorescent lamp 6 using the lamp support spring 3 as a fulcrum. When the lamp pin 7 is lifted upward, the lamp pin 7 is lifted diagonally upward from the bottom and outside and is inserted into the pin insertion part 9 of the lamp socket 10. When the lamp support spring 3 is completely released, the lamp support is removed. The outward spring force of the spring 3 firmly holds the lamp pin 7 inserted into the lamp socket 10 and secures the connection of the connection terminal 11 to the socket connector 16, so that the round fluorescent lamp 6 is Gain full mechanical support and electrical connections.

5 and 6 show different embodiments of the present invention, in which a socket connector 16 is provided on the mounting surface 5, and a connecting pin 17, which is a connecting terminal, is erected at the base end of the lamp socket 10. into the socket connector 16 and connect the lamp socket 1.
The lamp socket 10 in FIGS. 3 and 4 electrically connects and mechanically supports the lamp socket 10.
It is characterized in that the lamp socket 10 is removable from the mounting surface 5, and the lamp socket 10 can be changed arbitrarily to accommodate differences in lamp height depending on the appliance.

[Effect of idea]

As described above, the mounting structure of the round fluorescent lamp according to the present invention is such that the lamp socket connected to the socket connector attached to the fixture body and the lamp support spring are arranged approximately symmetrically, and the lamp support spring has a round shape at the support part. The device is characterized by holding a fluorescent lamp and pulling the lamp pin of the round fluorescent lamp inward into the apparatus main body and inserting it into the lamp socket and holding it therein. Just hook it up.
In addition, simply inserting the lamp pin into the lamp socket in this state completes the mounting support and electrical connection of the round fluorescent lamp, eliminating the hassle of lamp installation work and eliminating the risk of lamp damage. Since a terminal for connecting to the internal circuit of the lighting equipment is provided at the base end of the lamp, there is no need to insert the lead wire of the lamp socket into the main body of the lighting equipment as in the conventional case, making assembly and electrical connection operations easy. After the fluorescent lamp is installed, the outward spring force of the lamp support spring firmly holds the lamp pin inserted into the lamp socket, and also securely holds the connection terminal to the socket connector. Fluorescent lamps get full mechanical support and electrical connections.
