BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stand-type lighting device having a built-in electronic lighting device for lighting a lamp.

[0002]

2. Description of the Related Art FIG.
Shown in FIG. 3A is a front view, and FIG. 3B is a side view.
FIG. 4 is a sectional view of the main part. In this conventional stand-type lighting fixture, a lighting fixture main body 2 containing an electronic lighting device is attached to an upper surface of a base 1 which is installed on an installation surface to stabilize the installation, and a support 3 is provided above the lighting fixture main body 2.
Are rotatably projected via a support hinge 4 in a plane perpendicular to the installation surface. At the upper end of the support 3, two lamps 7 are arranged via a vertical hinge 5 and a horizontal hinge 6. Each of the two lamps 7 is equipped with a single-type fluorescent lamp, is rotatable in a plane perpendicular to the installation surface by a vertical hinge 5, and is arranged in parallel with each other by a horizontal hinge 6 so as to be substantially straight. It can be freely set between the arrangement and the lighting control.

The base 1 has a substantially circular base made of a steel plate base 8 serving as a weight for stabilizing the installation, and a plastic base cover 9 fixed to the base main body 8 and covering the upper surface. It is plate-shaped, and the base main body 8 and the lighting fixture main body 2 are directly screwed. The lighting fixture body 2 has a mounting plate 11 mounted substantially vertically including a center axis thereof in a substantially cylindrical bottomed cylinder formed by combining a pair of semi-cylindrical plastic body cases 10. The printed wiring board 13 of the electronic lighting device 12 connected to the two lamps 7 is attached to the lighting device 7, and the lower surface is covered with a main body attachment plate 14. The support hinge 4 is formed integrally with the lighting fixture body 2, a power cord 15 is introduced and connected to the electronic lighting device 12, and is wired from the electronic lighting device 12 to the lamp 7 through the support hinge 4. Lead wires have been derived. Further, a switch 16 is provided on the upper surface of the lighting fixture body 2 to control the lighting of the two lamps 7.

The mounting plate 11 is attached to the main body mounting plate 14 with a screw at a lower end, and is attached to one main body case 10 with a screw at one end. The printed wiring board 13 of the electronic lighting device 12 has a locking support 17 so that the printed wiring surface is perpendicular to the main body mounting plate 14.
To the mounting plate 11.

In recent years, with the development of electronic circuit devices, the number of devices for obtaining a DC power supply by full-wave rectification and smoothing of a commercial frequency has increased, and the increase in harmonics has become a social problem. There is a need to insert a harmonic suppression choke in an input circuit or to suppress harmonics by an electronic circuit.

[0006]

However, since the harmonic suppression choke uses a silicon steel plate as a core in consideration of the commercial frequency and the input current of the lighting device, it becomes heavier than other components of the lighting circuit. . For example, a lighting fixture for two 18W fluorescent lamps requires about 50 g of harmonic suppression choke. For this reason, when the harmonic suppression choke is mounted on the printed wiring board 13 shown in FIG. 4, solder cracks occur due to the weight of the harmonic suppression choke, or the copper foil is peeled off due to vibrations during transportation or the like. There is a problem that the board 13 is broken or an abnormality occurs in the printed wiring board.

In addition, there is a method in which the harmonic suppression choke is independently installed on the main body mounting plate 14 on which the mounting block of the electronic lighting device 12 is mounted. However, in this case, there is a problem that the number of assembling steps of the fixture increases. It is an object of the present invention to provide a stand-type lighting device that can mount a harmonic suppression choke without causing any trouble to a printed wiring board and without increasing the number of assembling steps.

[0008]

According to the stand type lighting apparatus of the present invention, a harmonic suppression choke is mounted on an end of a printed wiring board of an electronic lighting device, and the harmonic suppression choke is held by a bottom plate of the apparatus body. In this state, the printed wiring board is mounted perpendicular to the bottom plate of the appliance body.

[0009]

According to the structure of this invention, since the harmonic suppression choke is mounted on the printed wiring board of the electronic lighting device,
At the time of assembling, there is no increase in the number of assembling steps as in the case where the harmonic suppression choke is installed alone in the instrument body. In addition, the harmonic suppression choke is mounted on the end of the printed wiring board and is held by the bottom plate of the equipment body, so that the weight of the harmonic suppression choke is mounted on the printed wiring board mounted perpendicular to the bottom plate of the equipment body. Is not added, so that solder cracks occur and printed wiring boards
It is possible to prevent the printed wiring board from being troubled.

Further, since the harmonic suppression choke is held by the bottom plate of the appliance main body, heat generated by the harmonic suppression choke is radiated to the outside from the bottom plate of the appliance main body, and each component of the harmonic suppression choke and the electronic lighting device is formed. The service life can be extended and the ambient temperature fluctuation of the electronic lighting device can be suppressed, so that the reliability can be improved.

The overall appearance of this stand type lighting fixture is as follows:
This is the same as the conventional example shown in FIG. 3, in which a lamp 7 is supported by a column 3 protruding from a lighting fixture body 2 and hinges 4, 5, 6 are provided.
Thus, the position of the lamp 7 can be changed, and a detailed description thereof will be omitted. In FIG. 1, FIG.
Are denoted by the same reference numerals, and the following description will focus on those parts that are different from the conventional example.

As shown in FIG. 1, the lighting fixture body 2 includes
An electronic lighting device 12 in which electronic components are mounted on a printed wiring board 13 for lighting the lamp of the lamp 7 (see FIG. 3)
Built-in. A harmonic suppression choke 18 is mounted on an end of a printed wiring board 13 in the electronic lighting device 12 by soldering. And the harmonic suppression choke 18
The printed wiring board 13 is mounted by the locking support 17 so that the printed wiring board 13 is perpendicular to the main body mounting plate 14 in a state where the printed wiring board 13 is held by the main body mounting plate (bottom plate) 14 and the base main body (bottom plate) 9b via the insulating plate 19 It is attached to the plate 11. The mounting plate 11 is mounted perpendicular to the main body mounting plate 14.
