Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a lighting fixture using two annular fluorescent lamps.

[Background technology]

FIG. 2 shows a conventional lighting fixture. In the figure,
Reference numeral 21 denotes a main body of the apparatus, and lamp sockets 22 and 23 of a lamp holding type that also serve as glow sockets are provided. The outer lamp socket 22 is for the upper annular fluorescent lamp 24, and the inner lamp socket 23 is for the lower annular fluorescent lamp 25.
It is for use. The lower lamp socket 23 is attached to the appliance main body 21 via a mounting base 26. 27 and 28 are glow lamps, and 29 is a lamp holder. However, the lighting fixture configured in this manner has the following problems. Since the mounting base 26 is required for mounting the lower lamp socket 23, the number of parts increases. Further, when the terminal portion of the lower lamp socket 23 separates from the appliance main body 21, the lead wire 23a is drawn out, which also poses a problem in terms of process. Further, the lamp sockets 22 and 23 are connected to an annular fluorescent lamp 24,
25, uneven illuminance occurs on the irradiated surface. Furthermore, annular fluorescent lamps 24, 25
is provided parallel to the main body 21 of the device, so that it can be adjusted to fit the upper annular fluorescent lamp 24, which has a large diameter.
The device body 21 also becomes large.

[Purpose of invention]

The purpose of this invention is to provide a lighting fixture that can eliminate the socket mount, reduce the number of parts, facilitate wiring, prevent uneven illumination on the irradiation surface, and reduce the size of the fixture body. That's true.

[Disclosure of invention]

The lighting equipment of this invention includes a large-diameter annular fluorescent lamp disposed in front of the equipment body in an inclined position with the cap close to the equipment main body, and a large-diameter annular fluorescent lamp with the cap located inside the large-diameter lamp. a small-diameter annular fluorescent lamp disposed in an intersecting manner with an inclination in the opposite direction to the large-diameter lamp close to the lamp; and a ring-shaped fluorescent lamp of a small diameter arranged in an intersecting state inclined in the opposite direction to the large-diameter lamp; a large-diameter lamp socket and a small-diameter lamp socket; a large-diameter lamp holder that is attached to the apparatus main body on the outside of the small-diameter lamp socket and holds the side opposite to the base of the large-diameter lamp; The lamp holder includes a small-diameter lamp holder that is attached to the apparatus main body inside the lamp socket and holds the opposite side of the small-diameter lamp from the base.

According to the structure of this invention, the large-diameter and small-diameter annular fluorescent lamps are arranged in an intersecting manner with their bases close to the fixture body and inclined in opposite directions, so that the lamp sockets of both lamps can be connected directly to the fixture body. Can be installed on. Therefore,
The conventional socket head is no longer required, reducing the number of parts. Furthermore, since the lamp socket is directly attached to the appliance body, the lead wire does not float up and be pulled out from the appliance body, making the wiring process easier. In addition, since a small-diameter lamp and a large-diameter lamp are located in front of the large-diameter lamp socket and small-diameter lamp socket, respectively, it is possible to prevent the shadow of the lamp socket from forming on the irradiation surface, which can cause uneven illuminance. In addition, because the small-diameter lamp is placed inside the large-diameter lamp, and both lamps are arranged at an angle, the space required for installing the lamp is small, and the device itself can be made smaller. can.

Embodiment An embodiment of this invention will be described based on FIG. That is, a large diameter lamp socket 31 and a small diameter lamp socket 31 which also serve as glow sockets are provided in the main body 30 of the appliance.
32 are arranged diametrically apart from the annular fluorescent lamps 33, 34. Then, the ring-shaped fluorescent lamps 33, 34 of a small diameter and a large diameter are arranged in an intersecting state with their bases close to the instrument main body 30 and inclined in opposite directions to each other.
Connect each base of 4 to a small diameter lamp socket 3.
2 and large-diameter lamp socket 31.
Reference numeral 35 denotes a large-diameter lamp holding spring attached to the appliance body 30 outside the small-diameter lamp socket 32, and holds the lower end of the large-diameter lamp 34 on the side opposite to the base. Further, 36 is a small-diameter lamp holding spring attached to the fixture main body 30 inside the large-diameter lamp socket 31.
It holds the lower end on the opposite side from the cap part of No.3. Note that 37 is a glow lamp.

According to the lighting fixture constructed in this way, both lamp sockets 31 and 32 are attached directly to the fixture body 30, and both lamps 33 and 34 are attached in a crossed state, so that the conventional socket mounting base shown in FIG. 26 is no longer necessary, and the number of parts is reduced.

In addition, the lamp sockets 31 and 32 are connected to the appliance body 3.
Since the lead wire is directly attached to the main body 30, the lead wire is not lifted up and pulled out from the instrument body 30, and the wire connection process is facilitated.

Furthermore, since the small-diameter lamp 33 and the large-diameter lamp 34 are located in front (below) of the large-diameter lamp socket 31 and the small-diameter lamp socket 32, respectively, the shadows of the lamp sockets 31 and 32 are not cast on the irradiation surface. This prevents uneven illumination from occurring.

Further, the small diameter lamp 33 is arranged inside the large diameter lamp 34, and both the lamps 33 and 34 are arranged at an angle. Therefore, with the instrument main body 30 having a size to which the large-diameter lamp 34 in an inclined position can be attached, each of the large-diameter and small-diameter lamps 34 and 33
can be attached, and the instrument main body 30 can be made smaller.

Furthermore, since the large-diameter lamp holder 35 is located outside the small-diameter lamp socket 32, and the small-diameter lamp holder 36 is located inside the large-diameter lamp socket 31, it is easy to attach and remove the lamps 33 and 34. The lamp holders 35 and 36 do not get in the way, and the lamps 33 and 34 can be easily attached and detached. Moreover,
Since the lamp holders 35 and 36 each hold the lamps 34 and 33 from the outside, shadows of the lamp holders 35 and 36 are less likely to appear on the irradiation surface, and the lamp holders 35 and 36
It is possible to prevent uneven illuminance from occurring due to 5 and 36.

[Effect of idea]

According to the lighting equipment of this invention, the following effects can be obtained.

Since the large-diameter and small-diameter annular fluorescent lamps are arranged in an intersecting state with their bases close to the appliance body and inclined in opposite directions, the lamp sockets of both lamps can be directly attached to the appliance body. Therefore, the conventional socket base becomes unnecessary, and the number of parts is reduced.

Since the lamp socket is directly attached to the appliance body, the lead wire does not float up and be pulled out from the appliance body, making the wiring process easier.

Since a small-diameter lamp and a large-diameter lamp are located in front of the large-diameter lamp socket and the small-diameter lamp socket, respectively, it is possible to prevent the shadow of the lamp socket from forming on the irradiation surface, and uneven illuminance does not occur.

Place a small diameter lamp inside a large diameter lamp,
Moreover, since both lamps are arranged at an angle, the space required for installing the lamps is small, and the main body of the apparatus can be made smaller.
