DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture.

[0002]

2. Description of the Related Art As shown in FIGS. 4 and 5, there is a lighting apparatus in which a main body 30 constituting each side of a mouth-shape has the same shape. 31 is a suspension bolt.

[0003]

However, this lighting fixture has drawbacks in that the number of hanging bolts 31 to be used is large and it is difficult to carry out construction work alone. There was also a lighting device in which the device body was integrally formed in a mouth shape, but had the same disadvantage.

Accordingly, it is an object of the present invention to provide a lighting fixture which can reduce the number of parts and can perform the installation work of the mouth-shaped fixture main body alone.

[0005]

A lighting fixture according to the present invention comprises:
A pair of elongated first instrument bodies having locking portions on both end surfaces, and locking receiving portions that are held in parallel in the lateral direction and lock the locking portions are provided at both ends of the opposite side wall. And a pair of elongated second device main bodies, and suspends the second device main body.
Suspended by bolts, two-light safety
A stabilizer is provided, and the ballast is run from the ballast to the first instrument body.
It is characterized by supplying a loop current .

[0006]

SUMMARY OF] According to the present invention, more kept bolt hanging parallel pair of second instrument body in the lateral direction, engagement of the first instrument body engaging portions of the second instrument body It is assembled and constructed in the shape of a mouth by locking the stop. Therefore, the number of parts can be reduced, and moreover, the construction work of the mouth-shaped appliance main body can be performed alone. Also, the second
A ballast for two lights is provided on the appliance body and
The first instrument body is reduced in weight to supply pump current.
To reduce the strength of the locking part without the need for hanging bolts.
The first device main body can be securely locked by the locking portion so that the second device
Can be locked to the tool body.

[0007]

An embodiment of the present invention will be described with reference to FIGS. That is, this lighting fixture has first fixture main bodies 1 and 2 and second fixture main bodies 3 and 4. The first instrument bodies 1 and 2 have a long shape having locking portions 5 on both end surfaces, and are shorter than the second instrument bodies 3 and 4. The first instrument bodies 1 and 2 are provided with a pair of lamp sockets (not shown) and a straight tube fluorescent lamp (not shown) mounted on the lamp sockets. Connector 6 (only part shown)
Is provided. In addition, a lead wire insertion hole 7 is formed on the end face, and a kick spring receiver 8 is formed on the inner wall as shown in FIG.
The lower surface accessory 10 is disposed in the openings of the instrument bodies 1 and 2 by locking the kick spring 9 of the lower surface accessory 10 to the kick spring receiver 8. The locking portion 5 is formed by bending a leaf spring, and one end thereof is connected to the first instrument main body 1.
2 is attached to the end face.

The second instrument bodies 3 and 4 are long and have locking receiving portions 11 which are held in parallel in the lateral direction and lock the locking portions 5 at both ends of the side wall 15 on the opposite side. , Is longer than the first device main bodies 1 and 2. Each of the second appliance bodies 3 and 4 has a hole through which two suspension bolts 16 pass, and a nut 17 is closed at the tip of the suspension bolt 16 to suspend the second appliance bodies 3 and 4. A ballast 18 for two lamps is attached to the center of the second fixture bodies 3 and 4, and a socket base 20 holding a lamp socket 19 is attached to both ends. The locking receiving portion 11 has a hole as an example, and the locking portion 5
To lock and fix the first instrument bodies 1 and 2,
It is formed in a squirt or mouth shape. Lock receiving part 1
1, a lead wire 21 for one lamp is drawn out of the ballast 18 from the lead wire insertion hole 13 and is inserted into the first instrument main body 1, 2 from the lead wire insertion hole 7. The connector 6 ′ is inserted and the connector 6 ′ at the tip is connected to the connector 6. A plurality of kick spring receivers 8 are provided on the inner side walls of the instrument bodies 3 and 4, and the kick springs 9 of the equipment plate 22 are provided at the ends.
And the kick spring 9 of the lower surface accessory 10
Is locked. The lock receiving portion 11 and the lead wire insertion hole 13 are formed on both side walls 15 and 23 of the second instrument bodies 3 and 4 for convenience of construction.

According to this embodiment, a pair of second instrument bodies 3 and 4 are held in parallel in the horizontal direction by hanging bolts 16 and the like, and the second By locking the locking portions 5 of the device main bodies 1 and 2, it is assembled and constructed in a mouth shape. Therefore, the means for holding the first instrument main bodies 1 and 2 becomes unnecessary, so that the number of parts can be reduced, and furthermore, the work for installing the mouth-shaped instrument main body can be performed alone.

That is, the number of the suspension bolts 16 can be reduced to only the second appliance main bodies 3 and 4, that is, four, so that the number of suspension bolts can be reduced by half as compared with the conventional example, and the first appliance main bodies 1 and 2 can be reduced. Can be attached to the second device main bodies 3 and 4 by locking them, thereby facilitating construction. Further, the first instrument bodies 1 and 2 can be used in place of the spacers of the second instrument bodies 3 and 4, and the space between the second instrument bodies 3 and 4 when the first instrument bodies 1 and 2 are locked. Easy to put out. Further, a ballast 18 for two lights is provided in the second appliance bodies 3 and 4, and the ballast is not provided in the first appliance bodies 1 and 2 and supplied from the second appliance bodies 3 and 4. Therefore, the first instrument bodies 1 and 2 can be significantly reduced in weight.

[0011]

The lighting fixture of the present invention has a pair of elongated first fixture bodies having locking portions on both end faces, and a pair of holding members which are held in parallel in the horizontal direction to lock the locking portion. Since a pair of elongated second instrument bodies having the receiving portions at both ends of the side wall on the opposite side are provided, the pair of second instrument bodies are held in parallel in the horizontal direction by hanging bolts or the like, By engaging the locking portion of the first device main body with the locking receiving portion of the device main body of No. 2 and assembling and constructing a mouth shape, the number of parts can be reduced, and the mouth shape device alone can be used. There is an effect that the construction work of the main body can be performed.
