Description

  The present invention relates to a cap diameter conversion device that converts a cap diameter of a light bulb or a bulb-type illumination (fluorescent lamp or LED).

  Conventionally, a base of a light bulb or a light bulb type illumination (fluorescent lamp or LED) (hereinafter referred to as a “light bulb” including a fluorescent lamp or LED) is a male spiral screw called “E26 type”. In general, an “E17 type” base having an outer diameter smaller than that of the “E26 type” has been used.

  Patent Document 1 proposes a lamp socket to which an English standard lampshade can be mounted and fixed and to which an “E17 type” light bulb can be mounted. Both the “E17 type” light bulb and the “E26 type” light bulb are proposed. It is not assumed to be used.

JP 2006-32306 A

  By the way, the “E17 type” light bulb cannot be mounted on the “E26 type” light bulb, and conversely, the “E26 type” light bulb is mounted on the “E17 type” light fixture. I can't.

  In this way, the light bulbs that can be installed differ depending on the lighting fixtures, which means that extra bulbs must be provided in excess of the necessary number in order to prepare for bulb breakage or failure due to their lifetime. is there.

  Then, an object of this invention is to provide the nozzle | cap | die diameter conversion apparatus which can use the light bulb with the same specification | standard of a nozzle | cap | die irrespective of the kind of lighting fixture.

  In order to solve the above-described problems, a cap diameter changing device according to the present invention has the following configuration.

[Configuration 1]
The first diameter female socket into which the first diameter bulb base is screwed and the second diameter bulb socket having a diameter larger than the first diameter are the same shape and are coaxial with the female socket. A first internal wiring connecting the male base with the second diameter, the central electrode of the female socket with the first diameter, and the central electrode of the second male base with the first diameter; And a second internal wiring connecting the outer peripheral electrode of the female socket of the diameter and the outer peripheral electrode of the male cap of the second diameter.

[Configuration 2]
A male cap of the first diameter, which has the same shape as the bulb cap of the first diameter, and a bulb cap of the second diameter, which is coaxially joined to the male cap and larger than the first diameter, are screwed. A female socket with a second diameter inserted therein, a first internal wiring connecting a center electrode of a male cap with a first diameter and a center electrode of a female socket with a second diameter, A second internal wiring connecting the outer peripheral electrode of the male cap with a diameter and the outer peripheral electrode of the female socket with the second diameter is provided.

  In the cap diameter changing device according to the present invention having the configuration 1, the bulb cap having the first diameter is screwed into the female socket having the first diameter, and the male cap having the second diameter has the second diameter. Since it is mounted on a lighting fixture for a light bulb having a male base, a light bulb having a light bulb base having a first diameter can be used in the lighting fixture for a light bulb having a male base having a second diameter.

  In the cap diameter changing device according to the present invention having the configuration 2, the bulb cap of the second diameter is screwed into the female socket of the second diameter, and the male cap of the first diameter is the first diameter. Since it is attached to a lighting fixture for a light bulb having a male base, a light bulb having a second diameter light bulb base can be used in the lighting fixture for a light bulb having a male base having a first diameter.

  That is, the present invention can provide a cap diameter changing device that can use a light bulb having the same cap standard regardless of the type of lighting fixture.

It is sectional drawing which shows the structure of 1st Embodiment of the nozzle | cap | die diameter converter which concerns on this invention. It is sectional drawing which shows the structure of 2nd Embodiment of the nozzle | cap | die diameter converter which concerns on this invention.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

[First Embodiment]
FIG. 1 is a cross-sectional view showing the configuration of a first embodiment of a cap diameter converting apparatus according to the present invention.

  As shown in FIG. 1, the cap diameter converting apparatus according to the present invention has a female socket 1 having a first diameter into which a bulb cap having a first diameter is screwed. In this embodiment, the “first diameter” is the diameter of the “E17 type” base.

  And this base diameter converter has the male base 2 of the 2nd diameter made into the same shape as the electric bulb base of a 2nd diameter larger diameter than a 1st diameter. In this embodiment, the “second diameter” is the diameter of the “E26 type” base. The male base 2 is coaxially joined to the female socket 1 by a main body case 3 made of a synthetic resin material.

  The center electrode of the female socket 1 and the center electrode of the male base 2 are connected by a first internal wiring 4. Further, the outer peripheral electrode of the female socket 1 and the outer peripheral electrode of the male base 2 are connected by a second internal wiring 5.

  In this base diameter changing device, a light bulb having an “E17 type” base is attached to the female socket 1, and a male base 2 is attached to a lighting fixture for a light bulb having an “E26 type” base. Therefore, a light bulb having an “E17 type” base can be used in a lighting fixture for a light bulb having an “E26 type” base.

[Second Embodiment]
FIG. 2 is a cross-sectional view showing the configuration of the second embodiment of the cap diameter converting apparatus according to the present invention.

  In addition, as shown in FIG. 2, the cap diameter conversion device according to the present invention has a male cap 6 having a first diameter that is the same shape as a bulb cap having a first diameter. Also in this embodiment, the “first diameter” is the diameter of the “E17 type” base.

  The cap diameter changing device has a female socket 7 having a second diameter into which a light bulb cap having a second diameter larger than the first diameter is screwed. Also in this embodiment, the “second diameter” is the diameter of the “E26 type” base. The female socket 7 is coaxially joined to the male base 6 by a main body case 3 made of a synthetic resin material.

  The central electrode of the male die 6 and the central electrode of the female socket 7 are connected by the first internal wiring 4. The outer peripheral electrode of the male base 6 and the outer peripheral electrode of the female socket 7 are connected by a second internal wiring 5.

  In this base diameter changing device, the male base 6 is mounted on a lighting fixture for a light bulb having an “E17 type” base, and the female socket 7 is mounted with a light bulb having an “E26 type” base. Accordingly, a light bulb having an “E26 type” base can be used in a lighting fixture for a light bulb having an “E17 type” base.

  The present invention is applied to a cap diameter conversion device that converts a cap diameter of a light bulb or a bulb-type illumination (fluorescent lamp or LED).
