Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a composite lighting device using a plurality of ring-shaped fluorescent lamps and a plurality of incandescent lamps in combination.

(Prior art) A complex lighting device using a plurality of ring-shaped fluorescent lamps and a plurality of incandescent lamps has conventionally been used in such a manner that the incandescent lamps remain naked at the center of each ring-shaped fluorescent lamp or between the ring-shaped fluorescent lamps. It was common to attach. On the other hand, lighting fixtures directly mounted on the ceiling are often used in order to widely use the indoor space. However, the lighting equipment mounted directly on the ceiling tends to be dark near the lighting equipment on the ceiling surface. A method of covering the entire surface including the side of the fixture with a light-transmitting cover or providing an opening in a side wall of the lighting fixture to illuminate a ceiling surface has been performed. At this time, if the light illuminating from the side of the lighting fixture is the light of the bulb and the light illuminating the space below the lighting fixture is the light of the fluorescent lamp, the aesthetic effect of the lighting atmosphere can be created from the difference in the light colors of the two. Can be.

[Problems to be solved by the invention]

When the incandescent electric air is installed between the annular fluorescent lamps as in the prior art, the radiant heat generated from the incandescent lamp heats the fluorescent lamp bulb, and in particular, the fluorescent lamp and the incandescent lamp are connected to each other by one. When covered with a light cover,
Since the heat generated from the bulb is confined in the translucent cover, the temperature rise of the bulb of the fluorescent lamp is further increased, the lamp current of the annular fluorescent lamp is increased, and the winding temperature of the ballast is abnormally increased. In addition to being dangerous, there was a fear that the life of the fluorescent lamp would be shortened.

An object of the present invention is to suppress the influence of a ring-shaped fluorescent lamp due to heat generated by juxtaposed incandescent lamps, and to obtain a compact and easy-to-handle composite lighting fixture.

[Means for solving the problem]

The object is to mount a plurality of ring-shaped fluorescent lamps and a plurality of incandescent light bulbs, in a ceiling-mounted complex lighting fixture, between the ring-shaped fluorescent lamps arranged in a plane, to cover the periphery and open the opening. This is achieved by installing a plurality of light bulb cases provided on the side wall of the lighting fixture, and storing the incandescent light bulbs in the light bulb cases, respectively. Can be formed.

[Action]

The present invention arranges a plurality of annular fluorescent lamps in a plane,
In a combined lighting device used in combination with a plurality of incandescent lamps, incandescent lamps are respectively disposed in adjacent spaces between the ring-shaped fluorescent lamps facing the peripheral wall of the combined lighting device, and each incandescent lamp is covered to form an opening. In each of the provided light bulb cases, the opening was opposed to the side wall of the composite lighting fixture, so that the irradiation light of the incandescent light bulb illuminated the ceiling surface of the periphery of the composite lighting fixture, and the irradiation light of the ring-shaped fluorescent lamp was the composite light fixture. Along with illuminating mainly the lower space of the luminaire, the incandescent light bulbs are each opened only to the side wall of the composite luminaire and are surrounded by a light bulb case covering the other, so that the radiant heat of the light bulbs is transmitted to the annular fluorescent lamp. Heat is radiated to the outside of the lighting fixture by concealing direct influence and opening the above-mentioned opening directly to the outside of the lighting fixture, and the bulb temperature of the ring-shaped fluorescent lamp rises, and There can be prevented from increasing.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings. First
FIG. 2 is a structural view showing an embodiment of the composite lighting apparatus according to the present invention, FIG. 2 is a plan view showing the apparatus main body of the above embodiment, FIG.
The figure is a plan view showing a device main body of another embodiment, and FIG. 4 is a plan view showing a device main body of still another embodiment. FIG. 1 is a perspective view showing the interior of the fixture main body 1 with the translucent cover 6 of the composite lighting fixture according to the present invention opened. FIG. 2 is a plan view of the fixture body 1 of the above embodiment. Four ring-shaped fluorescent lamps 2 are arranged on the fixture body 1 in a plane, and the ring-shaped fluorescent lamp 2 faces the side wall of the lighting fixture. , Four bulb cases 4 each having a trapezoidal planar shape are attached to adjacent gaps. The light bulb case 4 is covered except for an opening facing the side wall of the lighting fixture (in this embodiment, the side wall of the fixture main body 1), and the incandescent lamps 3 are respectively installed inside. In addition,
In the present embodiment, a spotlight 5 surrounded by a cylinder is attached to the center of the above-mentioned instrument body, and its opening corresponds to the opening provided in the center of the light transmitting cover 6. Translucent cover 6
The spring metal fitting 7 attached to the device is a locking tool for locking the light transmitting cover 6 to the device main body 1. The opening provided in the device main body 1 of this embodiment is formed by arranging long and narrow slits to form a window. However, the opening may be covered with a light-transmitting plate made of plastic or the like, and a hole or a gap for heat radiation is provided. It is desirable.

In the embodiment shown in FIG. 3, three circular fluorescent lamps 2 are housed in a circular appliance main body 1, and a planar shape is trapezoidal in a space formed between the adjacent annular fluorescent lamps and the outer periphery of the appliance main body. Three light bulb cases 4 are arranged, and the incandescent light bulbs 3 are housed inside the case 4 respectively.

In another embodiment shown in FIG. 4, three light bulb cases 4 each having a semicircular planar shape are used instead of the light bulb case having a trapezoidal planar shape in the above embodiment.

As shown in each of the above embodiments, the plurality of light bulbs used in the composite lighting device according to the present invention are covered with a light bulb case except for the opening facing the side wall of the lighting device, so that the radiant heat of the incandescent lamp is reduced. Since the bulb of the ring-shaped fluorescent lamp is not heated, and the heat generated by the lighting of the incandescent lamp is prevented from directly affecting the temperature rise of the bulb, the lamp current of the ring-shaped fluorescent lamp can be prevented from increasing. Furthermore, a light bulb case is provided in the space adjacent to the side wall of the lighting fixture and the ring-shaped fluorescent lamp, and the planar shape of the light bulb case is trapezoidal or semicircular, while suppressing the influence of heat generation of the light bulb as described above, and Since the lighting fixture can be formed in a small size, it is lightweight and convenient in handling, so that workability can be improved in mounting.

〔The invention's effect〕

As described above, a plurality of lighting fixtures according to the present invention is provided with a plurality of ring-shaped fluorescent lamps and a plurality of incandescent lamps, and in a ceiling-mounted complex lighting fixture, between each ring-shaped fluorescent lamp arranged in a plane. By installing a plurality of light bulb cases with openings around the side walls of the lighting fixture to cover the surroundings and storing incandescent light bulbs in each of the light bulb cases, the bulb temperature of the ring-shaped fluorescent lamp rises and the lamp current increases. By increasing the shape of the bulb case for covering the incandescent bulb to a trapezoidal or semicircular shape, it is possible to obtain a compact and lightweight composite lighting fixture with good workability in mounting.
