Description

[Detailed explanation of the idea] The present invention relates to a fluorescent lamp device.

Recently, from the viewpoint of energy saving, light bulbs have been replaced by 10
A ~20W non-linear fluorescent light is built into the globe, and a lighting device including a ballast and lighting tube is built in.
In addition, a fluorescent lamp device having a base for a light bulb, so-called a light bulb type fluorescent lamp, has been proposed or put into practical use.

This has the practical convenience of being able to turn on a fluorescent lamp by simply screwing the base into the light bulb socket, but the ones that have been proposed or put into practical use so far do not allow the fluorescent lamp to turn on once its lifespan is over. Most of the lamps are of the so-called disposable type, in which the entire lamp device is discarded. However, even after the lifespan of a fluorescent lamp has ended, the ballast and the like can still be used, so it is not a good idea from the standpoint of resource conservation to dispose of these as well. That is, the total price of the ballast, lighting tube, etc. that make up the lighting device accounts for more than 20% of the price of the entire fluorescent lamp device, and the price of the ballast accounts for a particularly large proportion.

The present invention was developed in view of these circumstances, and from the viewpoint of resource conservation, the fluorescent lamp side and the main lighting device, that is, the ballast side, can be separated at will, so that when the life of the fluorescent lamp ends, To provide a fluorescent lamp device which has a simple structure and is easy to handle so that only the fluorescent lamp side can be replaced and the ballast side can be reused.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a fluorescent lamp device, which is an embodiment of the present invention, comprises a fluorescent lamp storage section 1 and a cup with a cap 2. As shown in FIG. As shown in FIG. 2, the fluorescent lamp storage section 1 includes a globe 3 made of plastic or the like;
The main parts are a non-linear fluorescent lamp without a base, such as a ring-shaped fluorescent lamp 4, which is housed in the lamp, and an insulating base 5 provided in the opening of the globe 3. A fitting part 3a is formed in the opening of the glove 3 over the entire circumference thereof. In addition, four terminal pins 6a, 6b,
Terminals 6c and 6d are implanted, and one end of three hooks 7a, 7b and 7C are each fixed to the back surface of the base 5 on the outside with screws (not shown) or the like. The other ends are each bent into a hook shape,
A fluorescent lamp 4 is hooked to and supported by these.
Lead wires 8a and 8b connected to the electrodes (not shown) of the fluorescent lamp 4 are connected to terminal pins 6a and 6b, respectively, and lead wires 8c and 8d connected to the other electrode (not shown) are connected to the terminal pins 6a and 6b, respectively. It is electrically connected to the terminal pins 6c and 6d by soldering or caulking. Then, the base 5 is attached to the fitting part 3a of the glove 3.
The opening edges 5b of the two are fitted together, and both are screwed together with screws 9a, 9.
It is fixed at b.

The cap-equipped cup 2 includes a light bulb cap 10 provided at its top and a ballast 11 built into it.
, a lighting tube 12 also without a base, a noise prevention capacitor 13 connected in parallel with this, and a disc-shaped plate 1 provided at the opening of the cup 12 with a base.
4 is the main part. The stabilizer 11 is fixed to the capped cup 2 with rivets (not shown) or the like. The disc 14 is fixed to the cup 2 with a cap with screws 14a and 14b. The board 14 has four insertion holes 15a, 15b,
15c and 15d are provided, and each insertion hole, for example, the insertion hole 15a, faces a connecting portion, for example, a terminal plate 17a, which is fixed to the stepped portion of the insertion hole with a screw 16a, as shown in FIG. A split pin 18a is electrically connected to the terminal plate 17a by soldering or the like. For example, the portion of the insertion hole 15a into which the terminal pin 6 is inserted has a shape that changes continuously from wide to narrow (see FIGS. 4 and 5). Other insertion holes 15b, 15
The portions c and 15d into which the terminal pins are inserted also have a similar shape. One lead wire 19a of the ballast 11 is electrically connected by inserting its tip into the split pin 18a and being clamped, and the other lead wire 19b is similarly electrically connected to the split pin 18c. be done. In addition, the lighting tube 12
One lead wire 12a is connected to the split pin 18b, and the other lead wire 12b is connected to the split pin 18d in the same manner as described above.

Terminal pins 6a, 6a, 15b, 15c, and 15d are inserted into the insertion holes 15a, 15b, 15c, and 15d formed in the plate 14 of the capped cup 2, respectively, and are implanted in the base 5 of the fluorescent lamp housing 3.
6b, 6c, and 6d, and rotate the fluorescent lamp housing 3 in the direction of the arrow as shown in FIG. 4, the terminal pin 6a will be at position P ₁ as shown in FIG.
Move from to position P ₂ . As a result, the terminal pin 6a comes into contact with the terminal plate 17a and is electrically connected, and since the terminal pin 6a comes to be located on the narrow side of the insertion hole 15a, the expanded head of the terminal pin 6a is hooked onto the edge of the insertion hole 15. At the same time, the other terminal pins 6b, 6c, and 6d are also electrically connected to their corresponding terminal boards, and
Each is hooked into its corresponding insertion hole. Therefore, the lighting device is electrically connected to the fluorescent lamp 4, and the fluorescent lamp storage section 1 and the cup with cap 2 are combined. On the other hand, in the opposite direction from the above-mentioned combined state, the fluorescent lamp storage part 3 or the cup with cap 2
When rotated, the electrical connection between the fluorescent lamp 4 and the lighting device is disconnected, and the connection between the fluorescent lamp storage section 1 and the cup with cap 2 is released.

In the above embodiment, an annular fluorescent lamp was explained as a non-linear fluorescent lamp, but a U-shaped,
Of course, a non-linear fluorescent lamp such as a saddle-shaped one may also be used.

As explained above, the present invention is to detach and freely connect a fluorescent lamp storage part and a cup with a cap containing a lighting device including at least a ballast, and to connect a non-linear fluorescent lamp and a lighting device. The electrical connection of the device, the coupling of the fluorescent lamp housing and the cup with a cap, the disconnection of the electrical connection between the fluorescent lamp and the lighting device, and the coupling of the fluorescent lamp housing and the cup with a cap, respectively. Because they are constructed at the same time, the electrical connection structure and mechanical connection structure between the two are simple, and the operation of attaching and detaching the two is extremely easy. It is possible to provide a fluorescent lamp device in which the lighting device including the ballast can be reused by replacing parts with an extremely simple operation.
