Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture equipped with an incandescent lamp and a fluorescent lamp.

[0002]

2. Description of the Related Art Conventionally, as a lighting fixture of this type, for example, there is one disclosed in Japanese Utility Model Publication No. 1-7939.
FIG. 3 is a vertical cross-sectional view of the lighting fixture, and FIG. 4 is a bottom view of the lighting fixture without gloves.

A reflector 3 is provided in the center of the lower surface of the luminaire main body 1 attached to the ceiling surface 10, an incandescent lamp 6 is attached to the inside thereof, and an outer surface of the reflector 3 has an open lower surface for heat insulation. 4 is attached. The heat shield cylinder 4 on the lower surface of the luminaire main body 1.
An annular fluorescent lamp 7 and a straight tube fluorescent lamp 9 are arranged outside the lamp, and a globe 8 is provided so as to cover the outside and the lower surface of the fluorescent lamp.
Is attached to the luminaire main body 1. The heat-shielding cylinder 4 is made of a light-shielding material, and the outside thereof is a mirror surface forming a reflection surface.

With the above construction, a relatively large amount of heat generated by the incandescent lamp 6 is carried away by the rising draft generated in the heat shield cylinder 4, so that the fluorescent lamp portion is overheated and the fluorescent lamps 7, 9 and the fluorescent lamps are heated. Does not overheat the ballasts and the like, and does not adversely affect them, and the light reflecting from the fluorescent lamps 7 and 9 is reflected by the reflection surface on the outside of the heat shield cylinder 4 to enhance the illumination effect of the fluorescent lamps. It has the aim of trying.

[0005]

However, in the above-mentioned prior art, when only the fluorescent lamp is turned on, the lower surface of the heat shield cylinder 4 is dark, and when only the incandescent lamps 6 and 9 are turned on. Only the lower surface of the heat shield cylinder 4 is bright and the gloves 8
The part was in a dark state. In recent years, it has been demanded that both a fluorescent lamp and an incandescent lamp be provided to enhance the effect of brightness and light color, and the lighting fixture itself looks more beautiful. The state is unfavorable because it impairs aesthetics and is a problem.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and is a lighting device provided with an incandescent lamp and a fluorescent lamp, and either the incandescent lamp or the fluorescent lamp is turned on. Therefore, it is an object of the present invention to provide a bright luminaire for both the globe portion that covers the bottom of the fluorescent lamp and the lower surface portion of the incandescent lamp.

[0007]

Therefore, the luminaire according to the present invention is provided with an incandescent lamp mounted on the lower surface of the central portion of the luminaire main body, and a heat shield for enclosing the outer peripheral portion of the incandescent lamp with the lower end surface opened. A lighting fixture comprising: a heat-shielding cylinder, a fluorescent lamp attached to the outside of the heat-shielding cylinder, and a translucent globe that covers a lower portion of the fluorescent lamp, the heat-shielding cylinder. An object of the present invention is to achieve the above-mentioned object by a structure characterized by being transparent and capable of illuminating the inside of the globe with the incandescent lamp and illuminating the inside of the heat shielding cylinder with the fluorescent lamp. It is a thing.

[0008]

[Operation] With the above configuration, the light rays from the incandescent lamp pass through the heat-shielding cylinder to illuminate the inside of the globe even when the fluorescent lamp is off, and the light rays from the fluorescent lamp even when the incandescent lamp is off. Can penetrate the heat shield cylinder to illuminate the inside of the heat shield cylinder, and if either the incandescent lamp or the fluorescent lamp is lit, the globe part and the incandescent that cover the bottom of the fluorescent lamp Both of the lower parts of the lamp are bright, and the aesthetics of the luminaire can be improved.

[0009]

EXAMPLES Illumination equipment according to the present invention will be described below with reference to examples. FIG. 1 is a vertical cross-sectional view showing the configuration of an embodiment of the present invention, and FIG. 2 is a side view of another embodiment in which a plurality of lighting fixtures of the embodiment are combined. The parts corresponding to the above-mentioned conventional example are denoted by the same reference numerals.

Reference numeral 1 is a main body of the luminaire, and 2 is a heat shielding tubular body, which is attached to the lower surface of the central portion of the luminaire main body 1 and is a tubular body which opens the lower end surface and surrounds the outer peripheral portion of the incandescent lamp. Ventilation openings are provided on the end faces or upper side faces. 3 is a holder for removably screwing and mounting the heat shield cylinder 2 on the instrument body 1, and 5 is an incandescent lamp socket, and the ventilation opening is provided in the central portion of the heat shield cylinder 2 on the lower surface of the instrument body. It is installed so that it will not be blocked. 6 is an incandescent lamp located inside the heat-shielding tubular body 2, 7 is a fluorescent lamp mounted outside the shielding tubular body 2, and 8 is a light-transmitting globe that covers the lower side of the fluorescent lamp. 10
Is a ceiling surface, 11 is an incandescent lamp for indirect illumination provided above the central portion of the instrument body 1, 12 is an indirect light cover, and 13 is a mounting arm.

The heat-shielding cylinder 2 is made of a light-transmitting material and is formed into a light-transmitting thin-walled cylinder having a cylindrical shape, a rectangular tube shape, or other cross-sectional shapes and side shapes. Coloring or design may be appropriately applied.

With the above structure, since the heat-shielding tubular body 2 has a light-transmitting property, the incandescent lamp 6 can be used even if the fluorescent lamp 7 is turned off.
From the fluorescent lamp 7 is transmitted through the heat-shielding cylinder 2 to illuminate the inside of the globe 8, and the light from the fluorescent lamp 7 is transmitted through the heat-shielding cylinder 2 even when the incandescent lamp 6 is turned off. The inside of the body 2 is illuminated and the lower part of the incandescent lamp 6 is also bright, and the aesthetics of the lighting fixture can be improved. It is also possible to enhance the effect by applying a light-transmitting coloring and design to the heat shielding cylinder 2.

Further, the incandescent lamp in the heat shielding cylinder is cooled by an ascending air current generated in the heat shielding cylinder from the open lower surface toward the upper ventilation opening, and at the same time, the fluorescent light is attached to the outside of the heat shielding cylinder. It is possible to prevent the lamp from being thermally affected.

Further, as in the other embodiment shown in FIG. 2, a lighting equipment having a further improved lighting effect and aesthetic appearance of the lighting equipment itself can be obtained by combining a plurality of the lighting equipment of the above embodiments. Can be provided.

Further, the fluorescent lamp is not limited to the annular fluorescent lamp and may be a straight tube fluorescent lamp, and the number thereof may be arbitrary. The incandescent lamp can also be implemented as a plurality of devices together with the heat shielding cylinder.

[0016]

As described above, according to the present invention, since the heat shielding cylinder attached to the lower surface of the central portion of the illuminator body has a light-transmitting property, the fluorescent lamp is turned off. The light from the incandescent lamp passes through the heat shielding cylinder to illuminate the inside of the globe, and even when the incandescent lamp is off, the light from the fluorescent lamp passes through the heat shielding cylinder and the heat shielding cylinder. It is possible to illuminate the inside of the lamp, and if either the incandescent lamp or the fluorescent lamp is lit, both the glove part that covers the bottom of the fluorescent lamp and the bottom surface part of the incandescent lamp are bright, and the appearance of the lighting fixture can be improved it can.
