Description

[Detailed Description of the Invention] This invention relates to a multi-light lighting fixture including a plurality of lamps such as a chanterlier.

As shown in FIGS. 1 and 2, among this type of multi-lamp lighting equipment, a plurality of lighting fixtures each containing built-in lamps are attached to the fixture body 7 via support arms 4, 5.6. This is what I did.

A ballast and other parts are accommodated in the instrument body 7.

Generally, an auxiliary lamp called a baby light bulb is housed in the main body 7 together with the lighting parts, and the light from this auxiliary lamp is transmitted to the outside through a translucent cover 8 provided below the main body 7. It is radiated.

Note that 9 is a light fixture cover, and 10 is a fixture hanging tool.

By the way, in the conventional multi-light lighting equipment with the above configuration,
Since the cover of the instrument body 7 is often formed of a translucent material, a portion of the light from the auxiliary lamp may be radiated to the outside through the cover of the instrument body 7.

In such a case, the shadow of lighting components such as a ballast housed in the appliance body 7 will be visible from the outside through the body cover.

Therefore, the appearance when lit is unfavorable, and there is a risk that the product quality may be impaired.

If an opaque agent is mixed into the cover forming material (usually a synthetic resin) of the main body 7 in order to compensate for this drawback, the strength of the material will decrease and it will become brittle.

Further, if a light shielding plate is provided separately, the number of parts will increase, and the number of assembly steps will increase.

This idea was made with these circumstances in mind,
The purpose of this is that even if the main unit cover is made of a translucent material, the shadows of the parts inside the main unit will not be cast when the main unit is turned on, and there is no need to provide a special light shielding plate, etc., and there is no risk of cost increase. An object of the present invention is to provide lighting equipment for lights.

The details of this invention will be clarified below with reference to embodiments shown in the drawings.

Figures 3 and 4 are diagrams showing one embodiment of this invention.
Reference numerals 1, 12 and 13 are lamps with a built-in fluorescent lamp L, and these lamps 11 to 13 are connected to support arms 14 and 13, respectively.
It is attached to the instrument body 17 via 15 and 16.

The main body 17 has lamp lighting parts attached to the lower surface of a plate-shaped holding base 18, and these parts are covered with a main body cover 19.

That is, one open end of a cylindrical body 20 formed of a light-shielding member is bonded and fixed to the center portion of the lower side surface of the holding base 18 in the figure.

The cylindrical body 20 is, for example, formed in the shape of a square tube or a triangular tube as shown in FIG. 5 or 6, and a mounting piece 21 is provided at one opening edge.

Further, a hole 22 for attaching a stabilizer is provided in a part of the peripheral wall.

A ballast 23, which is a lamp lighting component, is attached to the outer surface of the cylindrical body 20 using the attachment hole 22.

On the other hand, a mounting plate 24 is installed inside the cylinder 20, and a switch 25 and an auxiliary lamp 2 are mounted on this mounting plate 24.
6 is installed.

The other end opening of the cylindrical body 20 (lower opening in the figure) is close to or in contact with the bottom wall surface of the main body cover 19.

An opening is provided in the bottom wall of the main body cover 19 in close proximity to the opening of the cylinder 20, and an auxiliary lamp cover 27 is provided to cover this opening.

This cover 27 is for radiating the light from the auxiliary lamp 26 to the outside, and is made of a translucent material.

In the multi-lamp lighting fixture of the present invention configured in this manner, the light emitted by the auxiliary lamp 26 is exclusively transmitted to the auxiliary lamp cover 2.
It will be radiated to the outside through 7, and the body cover 1
This means that there is almost no intrusion into the interior of 9.

That is, since the cylindrical body 20 holding the stabilizer 23 is formed of a light-shielding member, the peripheral wall of the cylindrical body 20 functions as a light-shielding plate and prevents light from entering.

Thus, even if the main body cover 19 is made of a translucent material, the light from the auxiliary lamp 26 can illuminate the ballast 2.
The shadow of 3 is never reflected.

Further, since the cylinder body 20 is essential as a holder for holding the ballast 23, the switch 25, the auxiliary lamp 26, etc., providing the cylinder body 20 itself does not particularly increase the number of parts.

Therefore, it does not become a factor that increases costs.

Note that the stabilizer 23 is separated from the holding base 18 and the cylindrical body 20 is
Since the stabilizer 23 is attached to the peripheral surface of the stabilizer 23, there is also the advantage that the heat of the stabilizer 23 is less likely to be transmitted to the support arm or the like.

Note that this invention is not limited to the embodiments described above.

For example, in the above embodiment, a case has been described in which the shadow of the ballast 23 attached to the outer periphery of the cylindrical body 20 is not reflected on the main body cover 19. The situation is the same when the part is attached to the outer periphery of the cover 20, and it goes without saying that the shadow of the part can be prevented from being reflected on the cover 19.

Further, in the above embodiment, the case where the open end of the cylindrical body 20 is simply brought close to the bottom wall of the main body cover 19 has been described. A material or the like may be interposed.

In this way, it is possible to eliminate the gap caused by dimensional variations between the length of the cylinder 20 and the position of the bottom wall surface of the main body cover 19, and it is possible to more reliably prevent harmful effects caused by light leakage.

As explained above, according to this invention, a lamp lighting component is attached to the outer peripheral surface of a cylindrical body having a light-shielding property, and an auxiliary lamp is accommodated and installed inside this cylindrical body, so that the light of the auxiliary lamp is transmitted to the cylindrical body. Since it is led out from the body opening, even if the body cover is made of a translucent material, the shadows of the parts inside the body will not be visible from the outside when the light is turned on, and moreover, even if the body cover is made of a translucent material, the shadows of the parts inside the body will not be visible from the outside. There is no need to specifically provide
Therefore, it is possible to provide a multi-light lighting fixture that is free from the risk of cost increases.
