Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is an external perspective view of an embodiment of the present invention, and FIG. 2 is a diagram showing an equivalent circuit thereof, in which the same parts are designated by the same reference numerals.

The inverter power supply unit 1 has an integral structure with the socket 2.
Then, the transformer 11 converts commercial AC input power into AC power having a predetermined voltage value at a higher frequency, and also generates a preheating voltage for the filament on one end (one of the anode and the cathode) side of the slimline lamp 4. To do.

The inverter power supply unit 1 is provided with a pair of pins 3a and 3b protruding in parallel with each other. The pair of pins 3a and 3b are used to supply high frequency AC power from the transformer 11 to the outside. Has become.

The socket 2 integrated with the inverter power supply unit 1 is provided with a pair of holes 21 and 22 for supplying a preheating voltage to the filament at one end of the lamp 4. The filament preheating voltage is supplied to one end of the lamp 4 by fitting a protruding pin electrode from one end of the lamp 4 into 22.

The transformer unit 5 is also integrally formed with the socket 6, and has a pair of parallel pins 7a for receiving high frequency AC power supplied from the outside.
7b is attached so as to project. The transformer unit 5 is composed of a magnetic leakage transformer 51 to which the high frequency AC power supplied from the pair of pins 7a and 7b is input. The input AC power is stepped up (or stepped down) by this transformer 51 and also serves as a preheat voltage for the filament on the other end side (the other side of the anode and the cathode) of the lamp 4.

The socket 6 integrated with the transformer unit 5 has a pair of holes 6 for supplying a preheating voltage and step-up (or step-down) power to the other end filament of the lamp 4.
1, 62 are provided, and by fitting projecting pin electrodes from the other end of the lamp 4 into the holes 61, 62, filament preheating voltage and step-up (or step-down) power are supplied to the other end of the lamp. It is like this.

The inverter power supply unit 1 and the transformer unit 5 are connected to each other by a pair of pin receiving portions 8a, 8b arranged in parallel with each other and a pair of pins provided in each unit 1, 5 respectively. 3a, 3b and 7a, 7b.

That is, the pair of pin receiving portions 7a and 7b are
As shown in the enlarged view of the portion A in FIG. 1, the cross section is made of a conductive material having a substantially U-shaped groove, and the pins 3a, 3b and 7a, 7b of each unit can be fitted in the groove portion, respectively. It is also slidable.

The circuit operation will be described with reference to FIG. AC
The input is supplied to the inverter power supply unit 1, where high frequency AC power is generated by the transformer 11. A part of the voltage generated by the transformer 11 is sent to the holes 21 and 22 of the socket 2 for preheating the filament of the lamp 4 to heat the filament.

The other voltage is supplied to the pin receiving portions 8a and 8b through the pair of pins 3a and 3b. Then, it is taken out by the pair of pins 7 a and 7 b of the transformer unit 5 and supplied to the magnetic leakage transformer 51. In this transformer 51, this supply voltage is stepped up (or stepped down) and applied to the lamp 4. At this time, the transformer 51 has holes 61, 6 of the socket 6.
At the same time, the filament voltage required for the lamp is also supplied to 2.

In this case, one closed circuit is formed in the order of hole 21 → pin 3a → pin receiving portion 8a → pin 7a → hole 61 → lamp 4 → hole 21. With this closed circuit, the required voltage is continuously applied to both ends (anode and cathode) of the lamp 4, so that the lamp lighting can be continued.

Since the pin receiving portion has both the function of supplying the voltage generated by the inverter power supply unit to the transformer 51 and the function of flowing the lamp current flowing in the lamp, the wiring is extremely simplified. , Only the AC input wiring is required.

The pin receiving portions 8a and 8b are obtained by forming a pair of conductive members extending in parallel with each other in a substantially U-shaped groove as described above and molding the same with plastic. The slim line lamp 4 has various lengths, but even if the length of the lamp changes, by sliding one unit (the inverter power supply unit 1 or the transformer unit 5) along the pin receiving portion. The length of the lamp can be easily adjusted.

The pair of pins 3a, 3b and 7a, 7b
Are attached to the corresponding units 1 and 5, respectively, but may be attached to the sockets 2 and 6, respectively. Further, in the above embodiment, the sockets 2 corresponding to the units 1 and 5, respectively
Although 6 and 6 are integrated to improve the convenience of handling and the structural strength, they may be configured separately and connected to each other by wiring.

[0024]

As described above, according to the present invention, the inverter power supply unit, the lamp socket, and the external power supply pin are integrally structured, and the transformer unit, the lamp socket, and the external unit. Since the pins for receiving power from the unit have an integrated structure and are configured to transfer power between both units via a pin receiving portion into which these pins are slidably fitted, various types of slim line lamps can be used. The length can be flexibly accommodated, and the lamp mounting mode is not limited and complicated wiring is not required.
