JPH067527Y2 - High frequency lighting type circular fluorescent lamp fixture - Google Patents

Description

TECHNICAL FIELD The present invention relates to an annular fluorescent lamp fixture having a high frequency lighting device.

2. Description of the Related Art As shown in FIGS. 3 and 4, a conventional device of this type has lamp supporting springs 3 at three positions on a side portion of a main body 2 of a suspension type suspended by a cord 1, and Lamp sockets 6 and 7 that support the annular fluorescent lamps 4 and 5 and supply power to these lamps are provided separately on one side and the other side of the main body 2. A high-frequency lighting device 8 composed of an electronic circuit is housed in the main body 2 substantially at the center. Further, 9 is a bean ball and 10 is a drawstring for a built-in switch.

Problems to be Solved by the Invention In the above configuration, since the lamp sockets 6 and 7 are provided separately on one side and the other side of the main body 2, there is almost no need to worry about the inclination when the device is hung. However, when the lamp sockets 6 and 7 are concentratedly provided on one side of the main body 2, the appliance tilts. To solve this, high frequency lighting device 8
The position change is also one means, but the position cannot be easily changed considering the positional relationship with the switch, the mini ball 9, etc. described above. For example, the above-mentioned switch or miniature ball socket is directly attached to the circuit board constituting the high-frequency lighting device 8, or a notch is provided at the center of the circuit board so that the above-mentioned switch or miniature ball socket is placed in this notch. It is attached to the main body 2 so as to be located at. Therefore, when the circuit board is moved, the position of the drawstring 10 deviates from the center of the lower surface of the main body 2, and the device is rocked by the operation of the drawstring 10. The mold cost for changing the position of the hole through which the miniature ball 9 is inserted becomes difficult.

According to the present invention, when a plurality of lamp sockets are centrally provided on one side of the main body, it is particularly preferable that the lamp sockets with resin-made outer grains are projected from the main body without depending on so-called lead wires. The line is not exposed,
In addition, when the lamp socket itself also serves as a lamp supporting device and has a structure advantageous in production, the above problems are all solved.

Means for Solving the Problems The present invention has a lamp supporting spring on one side of a hanging type main body and a plurality of lamp sockets heavier than the lamp supporting spring on the other side. It is characterized in that a structure is provided in which a high-frequency lighting device composed of an electronic circuit is housed substantially in the center, and a balancer is provided near the lamp support spring of the main body.

Effects According to the present invention, the inclination of the appliance can be eliminated very simply and at low cost by providing the balancer in the main body near the lamp support spring.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

In these figures, the parts common to FIGS. 3 and 4 are designated by the same reference numerals.

In this embodiment, the lamp support spring 3 is provided on one side of the main body 2.
On the other side, a plurality of lamp sockets 11, 12 that are heavier than the lamp supporting spring 3 are concentrated. These lamp sockets are those in which a resin outer grain is provided from the main body 2 without a so-called lead wire, and an electric circuit board formed by punching out a conductive plate is arranged inside, and the lamp socket is annular fluorescent. It also serves as a support device for the lamps 4 and 5. And
A balancer 13 made of metal is provided near the lamp support spring 3 in the main body 2.

According to the present embodiment, the balancer 13 which does not need to be so heavy does not cause an inclination when the device is suspended, and further, the position of the high frequency lighting device 8 does not need to be changed. For example, there is no occurrence of a swing of the device when the drawstring is operated due to the shift of the drawstring 10 from the center, and no cost due to the change of the manufacturing die of the main body 2.

In addition, as a typical modified embodiment of the present invention, there is an example in which the lamp support spring 3 is further increased to two, and these and the lamp sockets 11 and 12 are provided at 120 ° intervals in the peripheral portion of the main body 2. .

EFFECTS OF THE INVENTION From the above, it is clear that the present invention has a lamp support spring on one side of the suspended main body and a plurality of lamp sockets concentrated on the other side, which are heavier than the lamp support springs. The inclination of the high-frequency lighting type annular lamp fixture can be solved very easily and at low cost by the balancer, and there is no other problem.
