Abstract

PROBLEM TO BE SOLVED: To overcome a problem on illumination capacity determined by the length of a circumference because light is emitted from a circumference part due to the annular shape of a circular fluorescent lamp suitable for a Japanese- style room. SOLUTION: A glass tube 1 of this fluorescent lamp is formed in spiral shape and arranged on the whole surface surrounded by the circumference to emit light. The illumination capacity is thereby enlarged.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent lamp in which a glass tube of the fluorescent lamp has a spiral shape.

[0002]

2. Description of the Related Art A conventional fluorescent lamp is a straight tube type fluorescent tube, an annular type in which a glass tube is bent annularly as a so-called circle fluorescent lamp, or a thin tube is bent into a U shape. It can be seen that the bundles are bundled together in the shape of a light bulb.

[0003]

Since the glass tube of the circline fluorescent lamp developed to have a structure suitable for a Japanese-style room is formed in an annular shape, it emits light from the circumference, and therefore the length of the circumference is small. Since the lighting capacity is determined, the circular diameter of the glass tube of the fluorescent lamp is made larger and smaller and arranged in a double ring, or multiple fluorescent lamps are arranged above and below to obtain the lighting capacity from a limited circular lighting fixture. Although it has been devised to increase the number, the illumination capacity is limited because the light is emitted from the circumference.

An object of the present invention is to provide a method for emitting light from the entire circular surface of a circular lighting fixture.

[0005]

In order to solve the above-mentioned problems, the present invention forms a long glass tube for a fluorescent lamp into a spiral shape so as to follow a circular shape toward the center of the circular shape. Since the curvature becomes larger with respect to the diameter of the glass tube, the electrodes are attached to both ends of the spiral shape to form an integral fluorescent lamp, so that it becomes a fluorescent lamp where it can be safely formed into a spiral shape. A glass tube having a diameter suitable for this curvature is formed into a spiral shape in the inner ring portion whose curvature increases toward the center further ahead, and this is arranged in the inner ring portion as the next spiral fluorescent lamp.

By the method as described above, the lighting equipment of the fluorescent lamp, which is the object of the present invention, for emitting and illuminating the entire circular surface can be obtained.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples with reference to the drawings. In FIG. 1, a glass tube 1 of a fluorescent lamp is bent and formed so as to be bent in a spiral shape toward the center, and the winding width of this spiral can be easily bent and formed according to the diameter of the glass tube 1, and an electrode is attached. When the outer peripheral edge 2 and the inner peripheral edge 3 are close to each other, bending is stopped to form an integral fluorescent lamp. Next, since the inner ring portion has a higher bending rate of the glass tube, the fluorescent lamp 4 formed by the glass tube having a diameter corresponding to this is arranged in the inner ring portion. In this way, a fluorescent lamp that illuminates the entire circular surface 1

In the embodiment shown in FIG. 2, the fluorescent lamps 1.4
The holding pieces 6 are provided at appropriate places from the disk-shaped base 5 so as to prevent the fluorescent lamps 1 and 4 from being fixedly held. Then, the sockets 7 and 8 are attached to the outer peripheral end 2 and the inner peripheral end 3 to which the electrodes are attached, and the sockets 9 and 10 are also attached to the fluorescent lamp 4 of the inner ring portion, and the wiring is concentrated from the socket 7 to the socket 8 through the disk-shaped base 5. In addition, wiring is similarly concentrated from the socket 9 to the socket 10, and the power socket 12 is connected to each socket 8.
・ Insert 13 to give the function of a fluorescent lamp.

Below the power sockets 12 and 13, a handle 19 is provided below the fluorescent lamps 1 and 4, and the handle 19 is pulled down with a fingertip to insert the power sockets 12 and 13 into the sockets 8 and 10. Keep the structure.

In the embodiment shown in FIG. 3, the fluorescent lamp 21.
The base for holding 24 is made into the shape of the inverted conical base 15, and the spiral fluorescent lamps 21 and 24 are formed in accordance with this, and the fluorescent lamps 21 and 24 are suspended by the holding piece 16 provided on the inverted conical base 15. To do.

In the embodiment shown in FIG. 4, in order to make the glass tube 31 of the fluorescent lamp into a rectangular spiral shape, each corner portion 33 is bent so as to have a spiral shape and is molded toward the central portion. In order to maintain the glass tube 31 in the shape of a square spiral, the shape maintaining protection piece 32 is inserted in an appropriate place between the glass tube and the adjacent glass tube. Sockets 37 and 38 are attached to the electrodes on both ends of the glass tube 31, and one socket 37 is connected to the other socket 38 by wiring, and a power socket 39 provided with a handle 49 is inserted into the socket 37 to function as a fluorescent lamp. give. A base 35 having the same shape as the outer contour of the glass tube 31 is provided above the glass tube 31, and the glass tube 31 is supported from below by a rigid rigid trunk 30 having a radial shape in order to hold the glass tube 31 by the base 35. The tip portion 29 of the thin rigid trunk 30 is hooked on the hanging piece 26 hanging from the outer edge of the base 35 to hold the glass tube 31 hanging from the base 35.

[0012]

Since the present invention is constructed as described above, it has the following effects.

Since a fluorescent lamp having a glass tube bent in a spiral shape is arranged over the entire surface from the outer circumference to the central portion to emit light, the lighting capacity is large, and since the fluorescent lamp has a spiral shape, it is divided into an outer ring portion and an inner ring portion. Can be arranged as spiral fluorescent lamps of different sizes.

[0014] One electrode of the fluorescent lamp is integrated into a socket attached to one electrode by wiring, and the power socket to be inserted into this is connected by pulling the handle provided below the power socket downward with your fingertips. Is easy.

Further, since the base is provided above the fluorescent lamp, it is easy to use this to centralize the wiring from one socket to the other. Moreover, the base is a long glass tube bent in a spiral shape and is subjected to gravity and vibration. It is possible to provide a holding piece at a suitable position so as to prevent the holding piece from being damaged by external force such as Although the base having the above-mentioned functions is circular, a cross-shaped base and covering the fluorescent lamp with this has the effect of having the above-mentioned functions. If the lower surface of the base is made glossy, the light emitted from the fluorescent lamp upward is reflected downward to increase the illumination capacity.

When the center portion of the spiral fluorescent lamp is lowered to form the inverted conical fluorescent lamp, the illumination light is radiated to the surroundings and the atmosphere of the illumination is good, and when the spiral fluorescent lamp is shaped into the inverted conical spiral lamp. Since a step is formed in the circumferential shape of the glass tube between the outer circumferential tube and the inner circumferential tube of the adjacent glass tube, it is possible to easily form the spiral shape of the glass tube.

When the fluorescent lamp is supported from below by a thin rigid trunk and is suspended from the bottom, the spiral glass tube is long and wound in a plurality of turns, so it is necessary to handle it carefully. However, this support method makes it easy to install a new fluorescent lamp or replace the fluorescent lamp. Furthermore, since a shape-maintaining protection piece is inserted between the spirally shaped glass tube and the adjacent glass tube, it is easy to handle because it is not damaged due to its long length of winding, and when it is attached to a lighting fixture. Even so, the shape of the fluorescent lamp is stable.
