Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture in which a socket holder accommodating a lamp socket is attached to a fixture body.

[0002]

2. Description of the Related Art Conventionally, when a lamp socket is attached to a fixture body, a preset lamp socket is attached to a socket mount provided on the fixture body.

[0003]

However, when it is necessary to attach a lamp socket of another type to the instrument body, the structure of the instrument body such as the socket attachment hole must be changed, and the standardization of the parts is required. There is a problem that cannot be achieved.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a lighting fixture which can standardize parts.

[0005]

SUMMARY OF THE INVENTION A lighting fixture according to the present invention comprises a lamp socket, a socket accommodating portion having a front surface formed with an opening for accommodating the lamp socket, and the socket accommodating portion formed around the opening. A socket holder for holding the periphery of the lamp socket, and a locking portion provided at the base end of the socket accommodating portion so as to be removably engaged with the instrument body; and a base end of the socket holder. And an instrument main body having an engaging portion that locks the locking portion.

[0006]

According to the present invention, the lamp socket is accommodated in the socket accommodating portion of the socket holder having the opening formed in the front surface, and the periphery of the lamp socket is retained by the retaining portion formed around the opening of the socket holder. In addition, the lamp socket can be housed in the socket housing part regardless of the shape of the lamp socket and attached to the appliance body by locking with the locking part provided at the base end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the lighting equipment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes an instrument main body having an arc-shaped reflecting surface formed on its surface, and has end plate portions 2 at both ends in the longitudinal direction of the instrument main body 1. The cross section of the end plate portion 2 is the same as the cross sectional shape of the instrument body 1, and a mounting hole 3 opening in a rectangular shape is formed on the surface of the end plate portion 2. A wall surface portion 4 is formed on the surrounding four surfaces inside the mounting hole 3, and the wall surface portion 4 is composed of a front surface 5, side surfaces 6, 6 and a rear surface 7. Then, on both side surfaces 6 and 6, locking recesses 8 and 8 elongated in the insertion direction are formed.
And a wiring insertion recess 9 is formed in the front surface 5.

Reference numeral 10 designates a synthetic resin integrally-molded socket holder. This socket holder 10 has a circular circular portion 11 on the distal end side as a base end portion 12 on which the instrument body 1 is attached. A rectangular holding portion 15 is formed on the base end side, and a wall-shaped holding portion 15 rises around the bottom surface portion 14 in a keyhole-shaped bottom surface portion 14 in which the circular portion 11 and the rectangular portion 13 are combined. Has been done. This holding portion 15 has an arcuate portion 16,
It has a linear portion 17 and a bottom portion 18, an opening 21 is formed at the tip side of the holding portion 15, and the bottom surface portion 14 and the holding portion are formed.
The inside of the portion surrounded by 15 is a socket housing portion 22. An electric wire insertion recess 23 communicating with the opening 21 is cut out in the bottom portion 18, and the linear portions 17, 17 are respectively formed.
Are provided with slender U-shaped cut grooves 24, 24 toward the bottom portion 18 to form locking portions 25, 25, and the tips of the locking portions 25, 25 project outwardly on the base end side. The locking claws 26 are formed.

Reference numeral 31 is a so-called L-shaped lamp socket. This lamp socket 31 has an arcuate portion 32 on the tip end side and a rectangular base end portion 33 on the base end side, and a front surface of the arcuate portion 32. A connecting portion 34 is formed which is movable back and forth to which the straight tube type fluorescent lamp FL is connected.

The lamp socket 31 has a socket accommodating portion in which the rear surface of the lamp socket 31 is brought into contact with the bottom surface portion 14 from the opening portion 21 of the socket holder 10 so that the front surface is substantially horizontal with the opening portion 21. It is designed to be stored in 22.

In such a structure, the lamp socket
31 is stored in the socket holder 10, and this socket holder 10
The operation of attaching the to the instrument body 1 will be described.

First, the opening 21 on the front surface of the socket holder 10
Therefore, the lamp socket 31 is housed in the socket holder housing portion 22. With this lamp socket 31 housed,
The periphery of the lamp socket 31 is held by the holding portion 15 of the socket holder 10.

The lamp holder 31 is attached to the socket holder 10.
In the state where is stored, the base end portion 12 of the socket holder 10,
It is inserted into the mounting hole 3 formed on the surface of the end plate portion 2 pre-mounted on the instrument body 1. At the time of this insertion, the tips of the locking claws 26 formed on both sides of the socket holder 10 are inserted while being pressed inward by the both side surfaces 6, 6 of the wall surface portion 4 which is the edge portion of the mounting hole 3, respectively. .. When the locking claw 26 is located in the locking recess 8, the locking claw 26 returns to its original state because it is biased in the expanding direction, and this return force prevents the socket holder 10 from coming off the instrument body 1. To prevent. Also,
The wire (not shown) connected to the socket 31 is introduced into the instrument body 1 through the wire insertion recess 23 and the wire insertion recess 9.

After mounting the socket holders 10 on both ends of the appliance body 1 as described above, as shown in FIG. 2, the lamp sockets housed in the socket holders 10, 10 are accommodated.
A straight tube type fluorescent lamp FL is sandwiched between 31 and 31.

Further, as the lamp socket 31, the round lamp socket 41 shown in FIG. 3 can be used. This lamp socket 41 has a round portion 42 at the tip and a rectangular base end portion 43 provided on the base end side of the round portion 42, and the round portion 42 is provided with a connecting portion 44. ing. In this case, connect the lamp socket 41 to the circular portion on the tip side of the holding portion 15 of the socket holder 10.
11, the base end portion 43 is positioned between the linear portions 17 and 17, and the lamp socket 41 is positioned and retained while preventing the rotation thereof.

According to the above-described embodiment, any socket can be used as long as it can be accommodated in the socket accommodating portion 22 of the socket holder 10. Lamp socket can be selected according to the customer's approval, and any lamp socket specified by the customer can be used.

[0018]

According to the lighting equipment of the present invention, the lamp socket is accommodated in the socket accommodating portion of the socket holder having the opening formed in the front surface, and the holding portion formed around the opening of the socket holder. By holding the periphery of the lamp socket and locking it to the fixture body with the locking part provided at the base end, the lamp socket can be housed in the socket body regardless of the shape of the lamp socket and attached to the fixture body. In addition, the standardization of parts can be achieved.
