Description

[Detailed Description of the Invention] This invention relates to a lighting fixture that can provide illumination suitable for various uses.

Traditionally, lighting equipment uses incandescent bulbs or fluorescent lamps as a light source, and is designed to emit light from this light source in one direction, either upward, downward, or sideways, and its purpose is not specific. , therefore, they were selected and used according to their respective uses.

However, for example, when using a lighting fixture with an incandescent bulb or fluorescent lamp light source arranged to emit light upward, the downward luminous flux is insufficient, so it is necessary to install a recessed lamp to compensate for the downward luminous flux. Supplementary lighting such as type incandescent lamps had to be used together.

Furthermore, lighting fixtures equipped with light sources that emit light downward or to the sides have the disadvantage of creating a poor indoor mood.

In addition, considering the heat generated by lighting equipment, conventional methods have been used to improve the indoor environment by using incandescent bulbs in the winter and fluorescent lamps in the summer. Nothing was thought of.

Therefore, conventional lighting equipment could only have a single function, so when using one room for multiple purposes or changing and expanding the purpose of use, separate auxiliary lighting is required. , it was necessary to replace the lighting equipment with new ones.

This idea was made in view of the above points, and involves providing a lamp base made of non-transparent material so as to cross and partition the interior of the storage body that houses the light source, and changing the positional relationship of these light sources and blinking. By combining these, we provide a lighting fixture that can provide illumination for various purposes.

An illustrated example in which this invention is applied to a multi-lamp lighting fixture will be explained below. 1 is a base body with a switch 2 installed inside it, and 3 is a support body consisting of pipe-shaped arms extending radially around this base body 1. A through hole 4 is provided above the end.

Reference numeral 5 denotes a lamp base made of two disc-shaped non-light-transparent materials having a space in the center for storing electrical wiring such as electric wires, and as shown in the figure, this lamp base is connected to a cover 12.5 which will be described later. 13, which is provided so as to traverse and partition the inside of a lamp body 6, which will be described later, and in FIG. 1, two spaces are formed above and below by the lamp base 5.

Reference numeral 6 denotes a lamp body in which a fluorescent lamp part 8 having a fluorescent lamp 7 on one side and an incandescent lamp part 10 having an incandescent lamp 9 on the other side are arranged inside through the lamp base part 5. Irradiation of light from the light bulb 9 and the fluorescent lamp 7 is regulated in one direction by the lamp base 5.

Reference numeral 11 is provided between a cover 12 that covers the fluorescent lamp 7 and a cover 13 that covers the incandescent lamp 9, and a double-sided bar 12
An annular frame for constructing a storage body by joining ゜13, 1
Reference numeral 4 denotes a support member consisting of a pipe-shaped insertion shaft whose one end passes through and is attached to the space of the lamp base 5, and whose other end extends outward from the lamp body 6 and is inserted into the arm 3. Screw holes 15 and 16 are provided at the top and bottom of the end, and an electric wire passes through the inside.

Reference numeral 16 denotes a mounting member consisting of a thumbscrew that screws the through hole 4 and the screw hole 15 together. It is fixed to the base 1.

In the lighting fixture configured as described above, the insertion shaft 14
The fluorescent part 8 and the incandescent lamp part 10 can be turned upside down by turning the screw holes 15 upside down and fixing them to the support body 3 using thumbscrews, that is, mounting members 16.

Therefore, the mounting member 16 functions as a mounting member for mounting the support member 14 on the support body 3 reversibly with respect to the extending direction of the support body 3.

Then, in each of the two mounting modes, if three types are combined: both the fluorescent lamp 7 and the incandescent lamp 9 are turned on, only the fluorescent lamp 7 is turned on, and only the incandescent lamp 9 is turned on, as shown in Figure 2. ~Various types of illumination are possible, as shown in Figure 7.

For example, as shown in FIG. 2, if the upper part is illuminated with a fluorescent light part 8 and the lower part is illuminated with an incandescent light part 10, the ceiling surface will be bright and a warm light will be obtained in the lower part, resulting in indoor lighting that creates a pleasant atmosphere.

As shown in FIG. 3, when the fluorescent lighting unit 8 in FIG. 2 is turned off,
Only the downward lighting can be obtained by the incandescent lamp part 10, and the warm illumination of the incandescent light bulb 9 is obtained.

As shown in FIG. 4, when the incandescent lamp section 10 of FIG. 2 is turned off, only the upper part is illuminated by the fluorescent lamp 8, and indirect illumination is provided by the fluorescent lamp 7.

As shown in Figure 5, the upper part is the incandescent lamp part 10, and the lower part is the fluorescent lamp part 8.
When irradiated as a light source, the fluorescent lamp 7 provides unique illumination that illuminates the downward direction.

As shown in FIG. 6, when the incandescent lamp section 10 of FIG. 5 is turned off, only the downward lighting is obtained by the fluorescent lighting section 8, resulting in bright and cool illumination by the fluorescent lamp 7.

As shown in FIG. 7, when the fluorescent unit 8 in FIG. 5 is turned off,
The incandescent lamp unit 10 can illuminate only the upper part, and the incandescent lamp 9 can provide subdued illumination, and various other types of illumination can be obtained according to various uses.

In addition, it is possible to use fluorescent lamps 7 and incandescent lamps 9 depending on the heat generated by the lighting equipment in summer and winter, and it is also possible to use indirect lighting and direct lighting, improving the indoor environment. It is something.

Incidentally, since the incandescent lamp section 10 is provided on an example of the disk-shaped lamp base 5, sufficient light distribution can be ensured.

In the above embodiments, a multi-lamp lighting fixture has been described, but it goes without saying that a single-lamp lighting fixture also has the same function.

As mentioned above, this idea is based on a lamp base made of an opaque material that is provided across the inside of the lamp to form two spaces, with a fluorescent part in one and a fluorescent part in the other. By providing an incandescent lamp part and making it possible to change the positional relationship between the fluorescent lamp part and the incandescent lamp part, various types of illumination are possible by combining the flashing states of the fluorescent lamp and incandescent lamp. This has the effect of creating a variety of indoor environments with a single lighting fixture.

Furthermore, since the two light source sections are partitioned by the lamp base housing the electric wiring section, no special member is required for the partition.

Further, since the fluorescent part and the incandescent lamp part are provided in the space on both sides of the lamp base that crosses the lamp body, sufficient light distribution can be ensured even for the incandescent lamp part.
