JP2003132853A - Reusable light bulb - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the problem of a light bulb, of which all parts except for a filament are usable, being discarded as being unusable only due to the filament being broken. SOLUTION: A reusable light bulb has two filaments, while the conventional bulbs have one filament in between two lead wires 4. Each of two filaments has two paths for the electrical current. The B-electrode of the bulb has two electrodes of B1-electrode 13 and B2-electrode. These electrodes are surrounded by a insulator 9 and are covered with rotational hemispherical cover 16 made of a conductor 15 and the insulator 9 capable of being turned on and off through rotation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is configured such that a conventional light bulb is composed of a necessary minimum amount, and one or all of the light bulbs cannot be used due to a failure or malfunction at one place.
The first relates to a technique for adding a spare part for a light bulb and a technique for using the spare part, which enables reuse by adding unnecessary spare parts.

[0002]

2. Description of the Related Art Conventionally, the current state of the art is that a light bulb is composed of the minimum necessary number of bulbs, and one of the bulbs cannot be used due to a failure or malfunction in one place.

[0003]

Light bulbs have been steadily improving since their invention, and the types thereof have been enormous. However, there is still room for improvement in self-help capacity related to breakdowns and malfunctions, and one failure or malfunction in one of them can render one or all of the light bulbs unusable, and in many cases, it is either abandoned or replaced. Even if it is used, its recycling is a considerable work, and it is difficult at present. By the way, although it has been described as "a failure or failure in one place", in the case of a light bulb, the failure or failure is almost the disconnection of the filament (2). The common, and almost only, cause of filament (2) breakage renders one bulb, all fully unusable, for other components. From the viewpoint of resource saving, which has become a problem in recent years, this is a point that improvement is desired, and it is possible to recognize the intermediate repair stage, which is the current perfect product or discarded product. It can be said that the absence of a state is one drawback in the present environmental society. The present invention has been made to solve this drawback.

[0004]

[Means for Solving the Problems] In a normal light bulb, one filament (2) is passed between two lead wires (4). All two of them, and finally the B pole and B1 pole (1
3) and B2 pole (14). The B1 pole (13) and the B2 pole (14) surrounded by the insulator (9) are
It is covered with a hemispherical conductor (15) and an insulator (9) and covered with a rotary cover (16) which can be turned on and off by rotation. The present invention is a "reusable light bulb" having the above-mentioned configuration.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. First, one filament (2) between two lead wires (4) of an ordinary light bulb is made into two filaments, and one electric path, that is, the lead wire (4) and the dumet wire (1)
1) and 2) are all used, and finally the electrodes also have two poles of B1 pole (13) and B2 pole (14). That is, A
The relationship between the poles (12) is the same as usual, but two parts, a B1 circuit and a B2 circuit, are prepared for the part preceding the filament (2), and while one part is working, the other part is a spare. The B1 pole (13) and the B2 pole (14) surrounded by the insulator (9) are connected to the hemispherical conductor (15) and the insulator (9).
(16) covered with a rotary cover that can be turned on and off by rotation. By the way, if the common filament (2) breaks while using a light bulb, there is no need to replace the light bulb itself as before.
The rotary cover (16) on the lower side of the light bulb can be rotated half a turn to switch from the previous B1 circuit to the spare B2 circuit, and the light bulb can be used as before. At this time, the number of anchors (3) is increased to two or more so that the cut filaments (2) do not overlap the spare circuit and interfere with it.

[0006]

By using the present invention, the life of a light bulb can be said to be approximately doubled. Of course, the number of circuits is not limited to two, but it is possible to increase it to three or more. , Space in the light bulb will be a problem. In order to make one light bulb, glass (1) is processed, and argon gas (10) is filled in it.
However, the present invention makes it possible to make the results of those operations longer and more effective.

Claims (2)

[Claims] 1. A filament of a light bulb and at least one spare lead wire and dumet wire, and a current wire leading to an electrode are provided, and even after a failure or malfunction occurs, the spare parts are used as they are before using a spare part. A reusable light bulb that provides functionality. 2. While the light bulb is performing its function, another
A rotating cover made of a hemispherical conductor and an insulator that prevents current from flowing in the other current line, and allows the bulb to function as before even after a failure or malfunction occurs.
