Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lighting fixture, and particularly to a lighting fixture that lights a fluorescent lamp using a high frequency lighting device.

[Conventional technology]

Conventionally, in lighting equipment equipped with a plurality of fluorescent lamps, a ballast for each fluorescent lamp is often used to turn on each fluorescent lamp.

By the way, in lighting fixtures using high-frequency lighting devices, which have been increasingly used recently, if one high-frequency lighting device is used for each fluorescent lamp as in the conventional lighting fixtures described above, direct mounting as shown in Fig. 4 is possible. It has a structure similar to a molded lighting fixture. That is, a plurality of lamp sockets 3 are arranged on the lower surface of a thin rectangular tray-shaped lighting device body 1 having a rising portion 11 on the periphery toward the upper surface side.
The single-cap fluorescent lamps 6 are mounted in parallel to each other in the lamp sockets 3, and the high-frequency lighting device 2' for one lamp, the power supply wire 10, and the wiring inside the fixture are installed between the single-cap fluorescent lamps 3. A plurality of single-cap fluorescent lamps are connected by connecting lighting parts such as a terminal block 8 to the lead wires 20, and connecting these lighting parts with the lead wires 20 to form a lighting circuit. Turn it on.

[Problem to be solved by the invention]

However, since the lighting equipment shown in Fig. 4 uses a high-frequency lighting device 2' for T-lights, not only does the wiring become complicated and unsightly, but the high-frequency lighting device 2' is There is a place where the lead wire 20 as the power input wire to the high-frequency lighting device 2' and the lead wire 20 as the output wire from the high-frequency lighting device 2' are adjacent and parallel to each other, and the output There is a risk that the high frequency of the electric wires will cause noise disturbances in the power supply line and cause problems with other electrical equipment, so it is necessary to take various noise countermeasures such as wiring methods, making the wiring even more complicated. There were problems such as impairing assembly workability and damaging the appearance. In addition, when trying to control the lighting of multiple single-cap fluorescent lamps using one high-frequency lighting device, as is often used in hanging lighting equipment, in a direct-mounted lighting equipment as shown in Figure 4, The light reflection situation differs between multiple single-cap fluorescent lamps with and without a high-frequency lighting device installed, and there is a risk of uneven brightness on the cover that covers the bottom of the lighting fixture. There is a problem.

The present invention has been made in view of the above background, and it is an object of the present invention to provide a lighting fixture that can reduce noise and improve ease of assembly and aesthetic appearance.

[Means for Solving the Problems] A lighting fixture according to the present invention has lighting components such as a high frequency lighting device and a lamp socket disposed on the lower surface of the lighting fixture body, and the lighting components are connected to each other to form a lighting circuit. In such lighting equipment, the lamp socket is placed closer to the L side of the lighting equipment body, and three or more single-cap fluorescent lamps are installed approximately parallel to each other, and the high-frequency lighting device is connected to the single-cap fluorescent lamp so that the output side is from the lamp socket. The high-frequency lighting device is arranged between the lights, and at least one of the high-frequency lighting devices is a high-frequency lighting device for two lights.

[Effect]

According to the present invention, the output side and the power input side of the high frequency lighting device can be separated, and wiring can be simplified.

〔Example〕

1 to 3 show one embodiment of the present invention, which will be explained below based on the drawings.

This lighting fixture is a direct-mounted lighting fixture that uses three single-cap fluorescent lamps as its light source.

The lighting fixture body 1, which is attached to a mounting surface such as a ceiling, has a thin rectangular tray shape with a rising part 11 on the periphery with a gap between the mounting surface and the top surface, and a high-frequency lighting device 2 for two lights on the bottom surface. Lighting components such as a high-frequency lighting device 2' for one lamp and a lamp socket 3 are provided, and the lower surface is covered with a cover (not shown). The lighting fixture body 1 has a circular power hole 12 in the center through which the ceiling cap 4 is inserted, and four mounting screws in which circular holes and circular arc holes are arranged at equal intervals around the power hole 12. After inserting the head of the mounting screw 5 screwed into the ear of the ear-equipped recessed rosette through the circular hole of the mounting screw hole 13 and rotating the lighting fixture body l. By tightening the mounting screws 5 and pushing up the lighting fixture body 1 onto the mounting surface, so-called simple installation without the need for electrical work in a house is possible. Further, a plurality of lamp sockets 3 are disposed on one side of the lighting fixture body 1, and a support spring 7 for holding the tip of a single-cap fluorescent lamp 6 attached to the lamp socket 3 is attached on the other side. There is.

High frequency lighting device 2 for two lights and high frequency lighting device 2 for one light
゛ is installed in different spaces between two single-cap fluorescent lamps 6, each with its output terminal facing the lamp socket 3 side, and the power input terminal facing the tip side of the single-cap fluorescent lamp 6. ing. ■High frequency lighting device for lights 2
A terminal block 8 is attached to the tip of the single-cap fluorescent lamp 6 between the same two single-cap fluorescent lamps 6 as shown in FIG. . These high-frequency lighting devices 2, 2°, lamp sockets 3, and other lighting components are connected by wiring to each other to form a lighting circuit by connectors 9, 9′ such as lead wires on the bottom surface of the lighting device main body 1. The connecting tool 9'' functions to supply power from the terminal block 8 to which the power wire 10 led out from the hook ceiling cassob 4 is connected to each high frequency lighting device 2, 2''. is connected between the output side of the high frequency lighting devices 2, 2' and the lamp switch 3.

In this lighting equipment, by taking the above-mentioned TL precept, the power input connector 9 of the high-frequency lighting device 2, 2" and the output connector 9 are not placed in close proximity, and there is no special problem in wiring. Noise countermeasures can be taken without the need for special consideration, wiring can be simplified, and the beauty of the lower surface of the lighting equipment body is improved when the cover of the lighting equipment is removed for replacing the single-cap fluorescent lamp 6, etc.

In addition, since this embodiment uses a single-cap fluorescent lamp 6, the output of the high frequency lighting device 2, 2° is transferred to the lamp socket 3.
The connecting tool 9 connected to the power source can be separated from the power source, and even more reliable noise countermeasures can be taken.

〔Effect of the invention〕

Since the present invention is structured as described above, noise countermeasures can be taken without the need for special consideration in wiring.
This simplifies wiring, improves assembly efficiency, and improves the appearance of the bottom surface of the lighting equipment when the cover of the lighting equipment is removed.
