Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a downlight fixture whose reflection efficiency can be adjusted for a plurality of types of lamps and a method of mounting the same, and more specifically to light emission of a light bulb lamp having a plug electrode. The present invention relates to improvement of the mountability of a light emitting means having a plug electrode of an instrument which can be used for illumination by mounting the means in a replaceable manner.

[0002]

BACKGROUND OF THE INVENTION As a lighting fixture, a type called a downlight that is embedded in a ceiling is known. That is, in the downlight fixture, the main body of the fixture equipped with the reflector is fitted into the embedded hole portion provided in the ceiling and fixed by the mounting metal fitting such as the spring plate, and the light emitting means such as a light bulb lamp is attached to the socket electrode provided in the main body. It is designed to be replaceable and is designed to be flat so that it does not project from the ceiling. Then, a part of the light emitted from the light emitting means is directly emitted downward, and the other part is reflected by the reflector and emitted downward. Thereby, the light emitted from the light emitting means in all directions is condensed downward and is efficiently irradiated.

The socket electrode is often provided with, for example, an E26 standard socket electrode for the purpose of mounting a general light bulb lamp (incandescent light bulb) as a light emitting means. This is due to the widespread use of plug electrodes.

By the way, recently, instead of mounting a light bulb lamp that consumes a large amount of power because of incandescent light emission, a fluorescent tube lamp called a fluorescent bulb is being replaced as a light emitting means. Since it is much less, it is preferred in terms of energy saving.

On the other hand, in the case of the fluorescent light bulb, as shown in FIG.
As shown in (a) to (d), although the plug electrode adopts a general E26 standard or the like for replacement compatibility with a light bulb lamp, the plug electrode has a length, due to requirements such as light emitting performance and decorativeness. Various products having different sizes such as thickness and shapes are manufactured. There is also a fluorescent light bulb in which a fluorescent tube lamp shown in the drawing is surrounded by spherical glass so that the appearance is similar to a normal light bulb.

For this reason, there is a demand on the side of lighting fixtures to cope with various fluorescent lamps having different sizes and shapes, but it would be very costly to manufacture a dedicated fixture for each type, and countermeasures are required. Was there.

That is, if fluorescent bulbs having different lengths and the like are attached to the same device, and the fluorescent bulbs have a long dimension and a part of the fluorescent bulbs is located outside the reflector, The light emitted from the portion outside the reflector cannot be used as illumination. Also, if the fluorescent bulb is short and the relative positional relationship with the reflector is not appropriate, the reflected light from the reflector cannot take a desired optical path and cannot be efficiently condensed at a predetermined location. However, there is a problem that the reflection efficiency (use efficiency) is reduced. Of course, in the case of an ordinary incandescent light bulb, the same problem occurs when the size and shape are different.

The present invention has been made in view of the above background, and an object of the present invention is to solve the above problems and to easily mount and replace various fluorescent lamps and other light emitting means. Moreover, even with different light emitting means, the relative positional relationship between the reflector and the light emitting means can be made appropriate, the reflection efficiency can be improved, and the illuminance can be increased with a small wattage,
It is an object of the present invention to provide a downlight fixture whose reflection efficiency can be adjusted for a plurality of types of lamps having high versatility and cost advantage, and a method of mounting the downlight fixture.

[0009]

Further, the lighting fixture may be a downlight which is fitted and mounted in a buried hole portion provided in a ceiling, for example.

On the other hand, in the method of installing the downlight fixture according to the present invention, the plug of the downlight fixture, which is used for illuminating, is equipped with a light emitting means such as a light bulb lamp having a plug electrode in a replaceable manner. When the socket electrode for screwing the electrode and the reflector for reflecting the light emitted from the light emitting means are attached and supported, and the adjusting means for changing the position of the socket electrode is provided, when the lighting fixture is attached to the ceiling or the like. First, the position of the socket electrode is adjusted by the adjusting means according to the light emitting means to be mounted, and then the main body of the device is set at the mounting position such as the ceiling and the mounting metal fitting is locked and fixed. The light emitting means may be mounted after this, or may be mounted in advance.

Further, the main body, which has been installed by the above-mentioned installation work method, is once removed in the reverse order, and the position of the socket electrode is readjusted by the adjusting means in accordance with the light emitting means to be newly installed. It is also possible to perform the mounting work again.

In the present invention, since the adjusting means for changing the position of the socket electrode is provided, the position of the socket electrode is

The main body 1 does not support the fluorescent light bulb 30 or the like as a light emitting means coaxially inside the reflector 2 but supports the fluorescent light bulb 30 or the like in parallel with the opening surface of the rim ring 10. It is composed of. As a result, a thin (low height) structure is adopted in which the height of the portion embedded in the ceiling can be kept low.

The frame 11 is provided with a guide opening 14 extending in a longitudinal direction at a portion rising from the rim ring 10, and a mounting spring metal fitting (not shown) is guided to the guide opening 14.
It is mounted and thereby fixed in association with the edge of the embedding hole provided in the ceiling. The reflector 2 is formed in a substantially cup shape, a mounting hole is provided at the center of the substantially cup shape, and an opening 20 for passing the fluorescent bulb 30 is provided on the peripheral side.

The socket electrode 3 is attached to the bottom surface of a bracket 5 formed in a substantially box shape, and a terminal board 6 for connecting to a power supply line is provided on the back side of the bottom surface.

A guide plate 1 protruding from the central portion of the frame body 11.
As shown in FIG. 4, both sides of the bracket 2 are folded, and the side surfaces of the bracket 5 are fitted between the folded edges. That is, the bracket 5 is fitted between the folded edge portions of the guide plate 12, and is guided along this. Then, the guide plate 12 is provided with an elongated hole 120 along the folding direction, and the side surface of the bracket 5 facing the screw hole 50 is provided at a position corresponding to the elongated hole 120.

On the other hand, when the fluorescent bulb 30 is changed to a different size and shape, the adjustment may be performed again. That is, the main body 1 is embedded in the hole portion 8 in the reverse order of the mounting work.
5, remove the fixing screw 7 or loosen or remove the fixing screw 7 to move the bracket 5 along the gap between the folding edges of the guide plate 12, and the size of the newly installed fluorescent bulb 30. , Tighten the fixing screw 7 at an appropriate position that fits the shape and fix it.

As described above, by the linkage of the guide and the fitting of the bracket 5 with respect to the guide plate 12, the socket electrode 3 is
Since the position of can be moved to the frame 11 side, that is, the optical axis of the reflector 2 in a far and near direction, and can be adjusted appropriately, various fluorescent bulbs 30 and the like can be properly mounted. This adjustment is easy because it is only necessary to loosen the fixing screw 7 and change the linking relationship between the long hole 120 and the screw hole 50, that is, it is easy to replace various fluorescent light bulbs 30 having different sizes and shapes, which is a general purpose. It is highly likely. As a result, a sudden specification change at the construction site, that is, for example, the planned fluorescent bulb 30 is no longer brought in because it is out of stock, and it is possible to respond even if the specification is changed to another stock item, and a simple adjustment is performed. As a result, it can be used for general purposes, so there is an advantage in terms of cost, and the construction process can be protected without modification, and construction period management is also advantageous.
